c37d6b8eb6 test(relay): cover system channels in the workflows API and push matcher (#8509)
🤖
## Summary
Test-only. This adds end-to-end coverage for the last two system channel
read paths that had none. It changes no behavior.

A system channel is a channel type the relay leaves out of ordinary
reads. A client sees one only when it names the channel or opts in. The
system channels spec lists every read path that must follow this rule.
The Postgres end-to-end tests already covered subscriptions, counts,
search, the HTTP bridge and membership notices, but not these two:

- **Workflows API.** A workflow names its channel, so reading a workflow
in a system channel follows ordinary channel access. Members can read
it. Outsiders can read it only when the channel is open. For a private
one, an outsider gets 404, the same answer as for a missing workflow.
- **Push notifications.** This is database-backed matcher coverage: the
test stores real channel rows, memberships and push leases, loads the
matcher's context from the database, and runs the production matcher. It
builds the match batch directly, so it does not cover the outbox or
gateway delivery. A member's push filter that names no channel gets a
wake for a message in an ordinary channel, but not for a message in a
system channel. A member's filter that names the system channel by `#h`
gets a wake for that channel only (the rule since #8517). A non-member's
filter gets neither.

### Related issue
Part of the system channels spec (risks section: end-to-end cases for
the workflows API and push). Rebased on #8507 and #8517, which made push
follow the read rule: a system channel pushes only to a member's filter
that names it by `#h`. No duplicate PR found.

### Testing
- Both tests pass against local Postgres and Redis on this branch.
- Each test fails when the behavior it covers is removed: without the
named-channel check in the workflows API, a member gets 404 for its own
system channel's workflow; if the push matcher lets a filter that does
not name a system channel match it, the member's broad lease also wakes;
if the matcher never pushes system channels, the named lease does not
wake.
- clippy (`--tests -D warnings`) and fmt pass.

cd8a968179 fix(relay): push system channel events to a lease that names them (#8517)
🤖
## Summary
Mobile clients can now get push notifications for a system channel, but
only when they ask for that channel by its ID. Before this change, the
relay never sent push for system channels, even when a client asked for
one directly.

System channels are channels the app uses for its own purposes (for
example, agent attention). They are hidden from clients that do not know
about them. #8507 made push use the same visibility rule as normal
reads: a push subscription sees a system channel, or any channel type
added later, only if its filter names that channel ID in `#h`. With that
rule, an older client can never get system channel pushes by accident.
The extra "never push system channels" rule in NIP-CL now only blocks
clients that ask on purpose, such as a future Live Activities
subscription. This PR removes that special case.

### Details
- `push_runtime.rs`: system channels now follow the same rule as other
named-only channel types. The relay still checks membership before it
sends a wake.
- `NamedOnlyChannels::is_system` had no other caller, so it is removed.
- NIP-CL and NOSTR.md now describe the shared rule instead of the ban.
- No behavior change for current clients. They do not name system
channels in their push subscriptions.

### Related issue
Follow-up to #8507 (see
https://github.com/block/buzz/pull/8507#issuecomment-6316180106).

### Testing
- `named_only_channel_pushes_only_to_a_filter_that_names_it` now expects
a wake for a system channel named by `#h`. It also checks that a broad
filter still gets no wake, and that a non-member still gets no wake.
- `cargo test -p buzz-relay --lib push_runtime`, `cargo clippy -p
buzz-relay --all-targets -D warnings`, and `cargo fmt --check` pass.

4dea51f644 fix(relay): scope push matches with the read path's channel rule (#8507)
🤖
## Summary
This is a consistency and forward-compatibility fix. It does not change
what users of current clients see.

Mobile push notifications now decide which channels can notify a device
with the same rule that reads use, with one exception that the protocol
requires: system channels never push.

Before this change, push and reads used two separate rules:
- **Reads** (subscriptions, counts, search and the bridge) show only the
original channel types (stream, forum, DM, workflow) unless the filter
names the channel.
- **Push** skipped only `system` channels.

Today `system` is the only non-original type, so the two rules give the
same result. But a channel type added later would be hidden from reads
and would still send push notifications to every member. This PR removes
that gap: push now calls the same function that reads use, so a future
type gets the correct push behavior with no extra work.

## What changes
- A channel of an original type pushes as before. Membership is still
required.
- A system channel never pushes, even when a push filter names it.
NIP-CL says: "The relay MUST NOT send push notifications for system
channels." This is the same as before.
- A channel of a type added later pushes only to a push filter that
names that channel with `#h` (the channel tag), as reads do.
- A push filter that names one channel does not get pushes from other
named-only channels.
- Events that are not in a channel (for example gift wraps) match as
before.

Push filters cannot carry the `#t` or `#P` opt-in that reads accept, so
for push, naming the channel means `#h` only.

## Impact on current clients: none
- System channels still never push, and no current channel type is
affected by the later-type rule.
- The mobile app names channels by `#h` only for joined, unarchived DM
channels (`mobile/lib/shared/push/push_subscription_provider.dart`). DMs
are an original type.
- Naming a channel cannot get around membership. A push filter that
names a channel still gets nothing unless its owner is a member of that
channel.
- Database cost is unchanged: one per-batch query replaces another, on
the same channel list, with no extra round trip.
- The push docs (NIP-PL and the push suppression doc) do not mention
channel types, so they need no update.

## Details
- The push matcher loads the named-only channels in each batch and
checks each lease filter with `filter_channel_scope`, the function REQ,
COUNT, search and the bridge already use. Before that check, it rejects
system channels outright.
- This removes `system_channel_ids_among`, which push was the last
caller of.

### Related issue
Part of the system channels spec (§2, rule 5). Builds on #8181 and
#8469. No duplicate PR found.

### Testing
- A `match_job` unit test covers: unnamed filters on an original-type
channel, on a channel-less event, on a system channel and on a
later-type channel; a later-type channel named by `#h` (1 wake); a
system channel named by `#h` (0 wakes); an unrelated `#h` (no widening);
and non-members. Removing either the shared scope check or the system
exception fails it.
- Before this PR, no test covered the push channel filter, not even for
`system`.

ce3fc78cbd feat(ws-client): send custom headers on the WebSocket upgrade (#8159)
## Summary

NIP-FI relays verify the `Nostr-Federated-Identity` assertion on the
WebSocket upgrade request (#7224) and pair it with the NIP-42 AUTH key,
but `NostrWsConnection` can only connect from a bare URL, so no
`buzz-ws-client` consumer can present an assertion today.

This adds two additive constructors:

- `NostrWsConnection::connect_with_headers(url, headers)`
- `NostrWsConnection::connect_authenticated_with_headers(url, keys,
auth_tag, headers)`

The existing `connect` and `connect_authenticated` delegate with an
empty `HeaderMap`, so their behavior is unchanged (`connect_async(&str)`
already went through `into_client_request`). `HeaderMap`, `HeaderName`,
and `HeaderValue` are re-exported so callers don't need a matching
`tungstenite`/`http` dependency.

Caller headers are added after the handshake headers; the doc comment
notes that supplying a handshake header such as `Sec-WebSocket-Key`
replaces it. tungstenite doesn't follow redirects, so upgrade
credentials can't be forwarded to another origin.

Follow-up (not in this PR): renewing assertions on long-lived
connections. The relay ends the session at the assertion's deadline, so
clients reconnect with a fresh assertion; that's caller policy rather
than a transport concern.

### Related issue

NIP-FI spec: #1485. Relay enforcement: #7224, #7264. No existing
client-side issue or PR found.

### Testing

- New `connect_with_headers_sends_headers_on_upgrade` test runs a local
`accept_hdr_async` server and asserts the header arrives on the upgrade.
Confirmed it fails when the headers are dropped.
- `cargo test -p buzz-ws-client` (4 passed)
- `cargo clippy -p buzz-ws-client -p buzz-test-client -p buzz-cli
--all-targets -- -D warnings`
- `cargo fmt --all -- --check`
- Not run: full `just ci` (desktop/mobile toolchains unavailable in my
environment) and an end-to-end connect against a local relay with NIP-FI
enforcement on.

76d792f288 BUZZ-357: feat(cli): token-lean agent output format for event reads (#8234)
### Why?

Agents read channel history with `buzz messages get/thread`. Every
returned event includes its 128-hex `sig`. Every agent-authored message
also carries a NIP-OA `auth` tag, which is another owner pubkey and a
128-hex signature. An agent can't use either of these, but pays for them
on every history read. Measured with Claude's tokenizer, that is about
88 tokens per human message and about 180 per agent message, so a
history read shrinks 33% for short human messages and 40% once agent
messages are in the mix (details in the comment below). The existing
`compact` format is fixed at `{id, content, created_at}` (#6884), which
drops the author, tags and reply target, so agents can't use it.

### What?

- **New `--format agent` for event reads.** Applies to `messages
get/thread/search` and `feed get`.
- Drops `sig`, and trims the NIP-OA `auth` tag to `["auth", <owner>]` so
agents can still tell an author is an agent and who owns it.
- Folds the NIP-10 `root`/`reply` tags into a `reply_to` field, using
the same resolver as relay ingest, plus `thread_root` on nested replies.
That's the value `messages send --reply-to` takes.
- Keeps every other tag exactly as `json` output shows it: channel,
mentions, edit targets, diff metadata.
  - Non-event reads return the same output as `json`.
- **Default for agents.** Without `--format`, the CLI falls back to
`BUZZ_OUTPUT_FORMAT`; an empty or unknown value means `json` with a
warning, so a harness/CLI version mismatch never breaks commands.
buzz-acp sets it to `agent` for every agent runtime through
`default_agent_env` and forwards the effective value in the explicit MCP
server environment, so operator or persona env still wins, and `--format
json` still returns full signed events. buzz-agent adds the variable to
its MCP env allowlist.
- **Docs and cleanup.** The managed-agent skill doc (version bumped to
7) and `AGENTS.md` describe the new default. The two duplicate
`format_events` copies in `messages.rs` and `feed.rs` are now one
`commands/event_output` module, which also does the NIP-10 tag parsing.
The `json` and `compact` output contracts are unchanged.



### Example output
https://github.com/block/buzz/pull/8234#issuecomment-6259679347

### Testing

Started `buzz-acp run` with the deterministic task-agent fixture, then
passed its `session/new` MCP environment to Codex 0.163.0 (`codex
app-server`). With no format override the MCP child received `agent`;
operator overrides of `json` and `compact` reached the MCP child
unchanged. The probes used temporary local sessions and made no model
requests.

### Related

Same change on the other agent read surfaces: each drops `sig`, trims
`auth` to `["auth", <owner>]` and keeps thread context.
- block/buzz-app#1388: buzz-app MCP read lines (text, `claimed
owner`/`reply_to`)
- squareup/cash-server#139132: hosted agents' read tools (JSON events,
raw NIP-10 tags)

7e6461242a feat(audio-client): accept a client request in connect (#8497)
## Summary

Related:
[block/buzz-app#1424](https://github.com/block/buzz-app/pull/1424)
(native federated sessions; attaches the assertion on Huddle audio once
this lands)

`buzz_audio_client::connection::connect` took the audio URL as `&str`,
so a host had no way to add headers to the WebSocket upgrade. buzz-app
needs to send its NIP-FI user assertion (`Nostr-Federated-Identity:
Bearer <jwt>`) on the Huddle audio socket. The relay checks NIP-FI when
the audio connection upgrades (`audio/handler.rs` →
`check_nip_fi_at_upgrade`).

This PR widens the parameter to `impl IntoClientRequest + Unpin`, the
same bound `connect_async_tls_with_config` already takes. Nothing else
changes: TLS, timeouts and the NIP-42 handshake work as before. Existing
`&str`/`&String` callers, including
`desktop/src-tauri/src/huddle/relay_api.rs`, compile unchanged.

a5767c67de fix(sdk): reject malformed mention pubkeys before signing p tags (#6372)
## Summary

`buzz_sdk::builders::mention_tags` lowercased whatever string it was
handed and pushed it straight into a `p` tag, so malformed mention
pubkeys were signed onto real events. A composer that mentioned someone
this way looked successful while notifying nobody, and the bad tag
propagated to every relay and client that read it.

Reproduced before fixing: `""`, `"not-a-pubkey"`, `"zzzz"`,
`"../../etc/passwd"`, and 63/65-character strings were all accepted and
emitted verbatim as `p` tags by `build_message` and `build_forum_post`.

Fixes #6291

## Acceptance criteria → evidence

Following @kiranmagic7's [recommendation on the
issue](https://github.com/block/buzz/issues/6291):

| # | Criterion | Evidence |
|---|---|---|
| 1 | Validate in the **private `mention_tags`**, not the public
`normalize_mention_pubkeys` | `crates/buzz-sdk/src/builders.rs` — the
single changed line inside `fn mention_tags`.
`normalize_mention_pubkeys` is untouched, so no public signature
changes. |
| 2 | Reuse the existing **`check_pubkey_hex`** helper | `let lower =
check_pubkey_hex(hex, "mention pubkey")?;` replaces
`hex.to_ascii_lowercase()`. No new helper added. |
| 3 | Reuse the existing **`SdkError::InvalidInput`** |
`check_pubkey_hex` already returns `InvalidInput`; no new error variant
is introduced. |
| 4 | Cover all **3 builders** |
`malformed_mention_pubkeys_are_refused_by_every_builder` asserts against
`build_message`, `build_forum_post`, **and** `build_forum_comment` — all
three share `mention_tags`. |
| 5 | Reject **empty / non-hex / 63-char / 65-char** | Same test's
table: `""`, `"not-a-pubkey"`, `"zzzz"`, `"../../etc/passwd"`, `"a"*63`,
`"a"*65`, plus `"z"*64` and a 64-char path-like string so a length-only
check cannot pass. |
| 6 | Preserve valid **uppercase canonicalization** |
`valid_mentions_are_canonicalized_and_deduped_across_case` — uppercase
hex is accepted and the emitted `p` tag is lowercase, across all three
builders. |
| 7 | Preserve valid **dedupe** | Same test: the same pubkey in both
spellings collapses to exactly one `p` tag. Pre-existing
`message_mentions_deduped` still passes. |
| 8 | Preserve **`TooManyMentions` precedence** for >50 |
`too_many_mentions_takes_precedence_over_validation` — a 51-entry list
that also contains a malformed entry still returns `TooManyMentions`.
The cap check stays ahead of validation.
`mentions_at_the_cap_still_sign` pins that the boundary itself did not
move. |
| 9 | Inspect **#3036 overlap**; keep the patch narrow | See the
compatibility note below. |
| 10 | Make these tests actually **gate** | `Justfile` +
`scripts/run-tests.sh` — see "Why the runner change is here". |

Out of scope by design: switching to `nostr::PublicKey::from_hex`. Its
stricter on-curve rule would change every one of `check_pubkey_hex`'s
~26 call sites, which is a repo-wide consistency decision rather than
part of this fix. The doc comment records that reasoning.

## Why validation lives in `mention_tags`

`mention_tags` is the single choke point every mention reaches, shared
by all three builders, and callers can hand those builders an explicit
list without ever going through `normalize_mention_pubkeys`. Validating
here closes that bypass without breaking the normalizer's public API.

This also aligns the SDK with behavior already shipping elsewhere:
desktop's own `events.rs::mention_tags` already validates with
`check_pubkey` on the identical structural rule (64 ASCII hex). The SDK
was the inconsistent one.

One malformed entry refuses the whole list rather than being filtered
out — a silently dropped mention is precisely the failure being fixed,
and filtering would preserve it.

## Why the runner change is here

Adding `buzz-sdk` to `just test-unit` and the mirrored
`scripts/run-tests.sh` fallback is a CI-behavior change, so it deserves
its own justification: **without it the regression tests above would
never run in CI.** `buzz-sdk` is a workspace member, so it was getting
`clippy` and `check`, but no CI job executed a single one of its tests.
This is the exact hazard the `Justfile` already warns about for other
crates — *"nothing in CI runs `cargo test --workspace` — workspace
membership alone buys clippy/check, not a single executed test."*

Verified with a positive/negative control rather than by reading the
config:

- **Negative control** — with the runner files at pristine `main` and a
deliberately panicking `buzz-sdk` test in the tree, `just test-unit`
exited **0** and printed "All tests passed!". The crate name never
appeared in the log.
- **Positive control** — same sabotaged test, with only these two runner
edits applied: `just test-unit` exited **1** with `buzz-sdk tests
FAILED`.

The sabotage test was removed afterward; it is not part of this PR. Both
entries are needed because the two lists (nextest path and the
no-nextest fallback) must stay in step. This is scoped strictly to
making the crate's existing tests execute — no other CI behavior is
touched.

## Compatibility with #3036

#3036 (`fix/nip10-reply-p-tags`) also edits `mention_tags`: it adds
`parent_author: Option<PublicKey>` to `ThreadRef`, emits a parent-author
`p` tag in `thread_tags`, and seeds `mention_tags`'s dedup set from `p`
tags already on `tags`. This PR replaces only the `let lower = ...` line
inside the loop, so the two changes are compatible in substance.
Mechanically, whichever lands second needs the trivial merge fixup:
#3036 adds `parent_author: None` to every `ThreadRef` literal, including
the ones in the tests added here.

One correction to the paragraph above, from an independent merge trial:
the fixup is not *only* the `parent_author: None` additions. Merging
#3036 into this head also produces one **textual conflict in
`crates/buzz-sdk/src/builders.rs`**, confined to the `mention_tags` doc
comment — both branches rewrote it, this PR to explain the validation
and #3036 to explain the seeded dedup set. The resolution is to keep
both blocks; there is no logic conflict, since this PR changes the `let
lower = ...` line and #3036 changes the `seen` initializer. For
reference, merging #3036 into plain `main` leaves `builders.rs`
auto-merging cleanly, so this conflict is specific to the combination.
Once the doc comment is resolved and `parent_author: None` is added to
the three new `ThreadRef` literals here, `buzz-sdk` compiles and the
only failing test is #3036's own `self_reply_drops_the_parent_p_tag` —
which fails identically with #3036 merged into `main` **without** this
PR, because `build_message` gained `.allow_self_tagging()` in #4975
after #3036's merge base.

## Test plan

- [x] `cargo test -p buzz-sdk` — **267 passed, 0 failed** (5 new tests;
pre-existing `message_mentions_deduped`, `message_too_many_mentions`,
and the three `*_preserves_self_mention_p_tag` tests still green)
- [x] `cargo fmt --all -- --check` — clean
- [x] `just clippy` (workspace, `-D warnings`) — clean
- [x] `just test-unit` — all 10 steps pass, now including `buzz-sdk`
- [x] `just file-size-check` — pass
- [x] `just desktop-tauri-fmt-check` / `desktop-tauri-check` /
`desktop-tauri-test` — pass (2684 tests; `desktop/src-tauri` consumes
`buzz-sdk`)
- [x] Full `just ci` — the remaining steps are JS/Dart (`desktop-test`,
`desktop-build`, `web-build`, `mobile-test`); this change touches only
Rust + two runner scripts, so CI covers them here

All gate results above were confirmed at commit
`5fe5929de39388cada354593ac875d3c42c3d830`.

## Open questions for maintainers

Out of draft and ready for review. Two calls I'd like from a maintainer:

1. **Do the runner entries belong here?** Adding `buzz-sdk` to `just
test-unit` and `scripts/run-tests.sh` is a CI-behavior change riding
along with a bug fix. I kept it because without it the regression tests
above never execute in CI (controls in the section above), but I'll
split it into its own PR on request.
2. **Is leaving `check_pubkey_hex` alone right for now?** Switching to
`nostr::PublicKey::from_hex` would add an on-curve check but changes the
contract at all ~26 call sites, which reads as a separate repo-wide
decision rather than part of this fix.

### A note on CI

The only check reporting here is **DCO Check** (pass). `CI`, `Desktop
Release Candidate`, and `Docker image` are all sitting in
`action_required` because this PR comes from a fork — a maintainer has
to approve the workflow run before they execute. That's the standard
first-time-contributor gate, not a failure, and I can't clear it from my
side. Every gate result in the test plan above is from local runs at
`5fe5929de39388cada354593ac875d3c42c3d830`, so CI has not independently
confirmed them yet.

fcdabcf774 docs(db): database target architecture and schema-change rules (#8273)
## Summary

Adds `docs/database.md`, which covers two things:

- **The target architecture.** `schema/tables/public/` is the
declarative source of truth, written within the constraints that
out-of-band, online schema tools can apply. Deployments at scale apply
schema changes out of band; auto-migration stays supported for smaller
and self-hosted deployments, and `migrations/` stays. The database has
no triggers, functions, or foreign keys; that behavior lives in the
owning application transaction or in durable application work. Data
repair runs through the backfill framework in `docs/data-backfills.md`,
not through migrations.
- **Rules for schema changes made now:**
1. Add no triggers, functions, procedures, rules, or foreign keys, with
no exceptions. New tenant-owned tables are fenced by community admission
in the application. Startup and deletion validation already tolerate
missing fences, but desired-state bootstraps still attach a fence
trigger to every `community_id` table, so a new tenant-owned table is
blocked until that loop stops (part of the fence-retirement work). The
doc includes checklists for adding a tenant-owned table and a
provenance-only table.
2. Migrations change schema only. They never mutate existing rows. Until
the backfill framework ships, a repair may be a reviewed, idempotent,
batched one-off script in `scripts/maintenance/` that takes the
community deletion lock and touches only active communities. A repair
that writes historical channel events must keep replica routing closed
until its WAL has replayed.
3. Update every schema location: `migrations/`, `schema/tables/public/`,
the manifest and sibling directories, the pgschema reconcile script
where it applies, and both homes of the existing `push_gateway_*` tables
(the target is for the gateway to own its tables alone). Never edit a
merged migration. Add catalog-level parity tests for what you touch.
4. Every migration must be safe for the relay that is currently
deployed, under both supported modes: auto-migration at startup and
out-of-band application. Either way the old relay runs against the new
schema for a while. Because auto-migration can apply expand and contract
in one boot, a contract migration must fail closed when its backfill has
not run, and a contract that depends on a writer release (such as
dropping a trigger whose work moved into the app) must name that release
as a required stop in the release notes, because no row check can prove
it. The order is expand, deploy, backfill, then contract. The doc
includes a table of changes that break the old relay and the safe form
of each.
5. Bound every lock, build `migrations/` indexes concurrently (the
declarative schema uses plain `CREATE INDEX`), and keep changes within
what out-of-band apply can make online.

AGENTS.md (Product Contract), ARCHITECTURE.md (buzz-db), and new
path-local `migrations/AGENTS.md`, `schema/AGENTS.md` (a pointer), and
`crates/buzz-push-gateway/migrations/AGENTS.md` point to the doc. The
path-local files mean agents editing those directories get the rules
automatically. AGENTS.md also had a stale claim that migrations are
"auto-applied on relay startup". This PR corrects it:
`BUZZ_AUTO_MIGRATE` defaults off in the binary and on in the Helm chart,
and both modes are supported.

## What got simpler

The rules were scattered across `schema/schema.sql` comments, AGENTS.md
Common Gotcha #7, the backfill spec, `docs/thread-window-deployment.md`,
and test names. They now live in one document, and the rest link to it.
No code changes.

## Testing

This PR changes documentation only. I checked links and diffs, and every
claim in the doc points to code at the base commit: the layout and
parity tests in `crates/buzz-db/src/runtime/migration.rs`,
`EXPECTED_SCOPED_TABLES` and the serving-catalog check in
`crates/buzz-db/src/store/deletion.rs`, and `BUZZ_AUTO_MIGRATE` in
`crates/buzz-relay/src/main.rs`. The new `AGENTS.md` files aren't
`.sql`, so neither the sqlx migrator nor the schema layout test picks
them up; CI's layout, migration-count, and deletion-parity tests pass.

At an earlier head, a real relay against isolated PostgreSQL 17 showed
that a new unfenced `community_id` table serves normally and makes
community deletion report `unknown=<table>`. Since then, the fence
requirement at startup was removed on main; the doc now cites
`migration_schema_fence_objects_are_optional_for_serving_and_deletion`
for that.

ca3be55018 fix(relay): advance the partition catch-all by default (#8464)
## Summary

The migrations leave `events` and `delivery_log` with a catch-all
partition that already covers every month from 2026-07. Only catch-all
advancement replaces it with monthly partitions. Advancement was off by
default, so any deployment that left out
`BUZZ_PARTITION_MANAGER_ADVANCE_ENABLED` routed every new row into the
catch-all. An operator then had to repair it by hand: drain the
catch-all, swap it for monthly partitions, and re-attach. This has
already happened in one staging environment.

- **Advancement on by default.**
`BUZZ_PARTITION_MANAGER_ADVANCE_ENABLED` now defaults to `true`, and an
explicit `false` still disables it.
`BUZZ_PARTITION_MANAGER_CREATE_ENABLED=false` remains the kill switch
for all automatic partition DDL.
- **Prompt retry while the current month routes to the catch-all.** If a
startup or periodic pass leaves the current month routed to an empty
catch-all that the maintenance planner would replace, the audit loop
retries on its existing backoff. That is 5 s, doubling to a 60 s cap,
for at most 8 retries (about 5 minutes). After that it returns to
`BUZZ_PARTITION_AUDIT_INTERVAL_SECS`. Before this change, a failed first
pass, such as a lock timeout during a rollout, waited the full 15
minutes.
- The routine monthly advance, where only the last lookahead month falls
into the catch-all, stays on the normal interval. Each attempt queues an
`ACCESS EXCLUSIVE` request on the parent, so it shouldn't be retried
without urgency.
  - The budget resets once the catch-all no longer awaits advancement.
  - A failed attempt keeps the last known state.
- Layouts the planner refuses, such as a catch-all that holds rows, need
an operator, so they are never retried early. Neither is a policy with
create or advance disabled.
- The check is `PartitionTableAudit::awaits_catch_all_advance(policy)`,
plus a `PartitionAudit` helper that applies it to every table. It is
derived from `plan_maintenance`, so it can't drift from the planner's
rules.
- **Fresh-install test.** A new `#[ignore = "requires Postgres"]` test
runs every migration in a dedicated database. It checks that both tables
start out waiting on the catch-all and that create-only maintenance does
not fix them. It then checks that the first pass with advancement
produces canonical monthlies, an empty `{table}_p_future`, trigger
parity and a non-degraded audit, and that a second pass is a no-op.

### Related issue

None found.

### Testing

**Automated:**
- `cargo test -p buzz-db --lib partition`, including `--ignored` against
local Postgres: 21 unit tests and 55 Postgres tests pass.
- `cargo test -p buzz-relay` for the config tests and the partition
schedule tests passes.
- `cargo clippy -p buzz-db -p buzz-relay --all-targets -- -D warnings`
and `cargo fmt --check` are clean.
- Mutation checks on `awaits_catch_all_advance`. Each fails the new unit
test:
  - matching any window month instead of the current month;
  - replacing the planner check with the policy flags alone;
  - short-circuiting the current-month gate.

**Local relay** (`BUZZ_AUTO_MIGRATE=true`, no advance env var):
- **Fresh database:** startup committed `advanced` for both tables,
creating `p2026_07` through `p2027_04` plus `_p_future`.
- **Failed first pass:** I held `LOCK TABLE ONLY communities IN SHARE
ROW EXCLUSIVE MODE` for 4 s across startup. The startup pass failed with
`lock_timeout` at 17:07:20.8, and the first periodic retry committed
`advanced` for both tables at 17:07:29.

039e1c8d59 feat(relay): write the NIP-43 member list in the membership transaction (#8482)
## Summary

The relay-signed NIP-43 member list (kind:13534) was published after
each membership change had already committed. If that publish failed, or
if a change never republished at all (startup `bootstrap_owner`), the
list stayed wrong until the background reconcile sweep found and fixed
it. #8467 moved that sweep off the startup path. This PR removes the
reason the sweep exists.

Now every `buzz-db` function that changes `relay_members` writes the new
list **in the same transaction**, as its last statement before commit:
- It takes the per-community list lock last, reads the members, signs
the list, retires the old one and inserts the new one.
- If the list write fails, the membership change rolls back and the
caller gets an error.
- A call that changes nothing (already a member, role mismatch, host
exists, limit reached) writes no list.

The functions return `MembershipWrite<T> { outcome, snapshot }`. Callers
push `snapshot` to live subscribers after commit. That push is the only
thing left outside the transaction; if it fails, live clients see the
change on their next fetch, and the stored list is already correct.

Write paths covered (RPR #2, every write path): `add_relay_member`,
`claim_relay_membership`, `claim_relay_invite`, `remove_relay_member`,
`remove_relay_member_if_role`, `update_relay_member_role`,
`bootstrap_owner` / `provision_owner`, `transfer_ownership`,
`backfill_from_allowlist`, and the owner insert in
`create_community_with_owner[_and_nip_fi_issuers]`. Community deletion
removes the members together with the community, so it writes no list.

The relay keypair is passed in explicitly instead of being stored on
`Db`, so the compiler finds every caller.

### Behavior changes

- **Open relays get an accurate list too.** Provisioning and ownership
transfer used to publish only when `require_relay_membership` was on.
The write is now unconditional.
- **Same-second changes can't reuse an id.** The list's `created_at` is
one second past the newest earlier list for that community, including
retired ones, or the current time if that is later. Before, adding and
then removing a member in the same second could produce an event with
the same id as an earlier list. The insert then failed, and the stale
list stayed live. A burst of changes can push `created_at` ahead of the
clock by up to one second per change; it returns to the clock once the
burst ends.
- **`buzz-admin add-member` / `remove-member`** no longer build their
own list (`publish_membership_list_with_bump` is deleted). They push the
list the database wrote. Concurrent CLI runs now serialize on the
database lock rather than depending on `run.sh` running one at a time.
- **Owner mutations lock the community row `FOR NO KEY UPDATE`.**
`transfer_ownership` and `bootstrap_owner` used `FOR UPDATE`. The list
insert takes `FOR KEY SHARE` on that row through `events.community_id`'s
foreign key, so a repair holding the list lock, or a removal or role
update holding a member row, deadlocked with a concurrent owner change.
`FOR NO KEY UPDATE` still conflicts with archive, unarchive and deletion
admission, so the lifecycle ordering is unchanged.
- **Startup delivers its list to other replicas.** When backfill or
`bootstrap_owner` changes members at startup, the relay fans the newest
list out through pub/sub once its state is ready, so clients connected
to other replicas during a rolling deploy see an owner rotation without
a refetch.
- **New `buzz-admin republish-members`.** Rewrites the community's list
from the stored members in one community-write transaction and pushes it
live. This replaces the sweep as the repair for a list that is missing
or stale: a `relay_members` change made directly in SQL, a restore, or a
deployment that turns on `BUZZ_REQUIRE_RELAY_MEMBERSHIP` after running
without it.

## Rollout

Nothing rewrites a list automatically once the sweep is gone. A
community whose list drifted before this deploys stays wrong until its
next membership change or until an operator runs `buzz-admin
republish-members`. Either deploy #8467 and let its sweep complete one
pass first, or run `republish-members` for each community after this
deploys. The command repairs only the community that `RELAY_URL` maps
to, so on a relay hosting many communities, run it once per community
host.

## What got simpler

Deleted:
- `reconcile_nip43_membership_snapshots`,
`spawn_nip43_membership_reconciler`, its leader lock key and #8467's
standby retry
- the three `nip43_membership_snapshot_needs_reconciliation*` drift
reads (one already deprecated)
- `publish_nip43_membership_list` / `publish_nip43_membership_locked`,
the separate after-commit republish at every call site, and
`buzz-admin`'s duplicate publisher
- the reconcile metrics `buzz_nip43_membership_reconciliations_total`
and `buzz_nip43_membership_reconciliation_failures_total`
- the after-commit publish metrics
`buzz_nip43_membership_publications_total` and
`buzz_nip43_membership_publication_seconds`, and the
`publish_nip43_membership_locked` transaction metric label. A failed
list write is now a failed membership write and shows up in the caller's
existing error handling and the transaction metrics of its write path.
- the `BUZZ_NIP43_RECONCILE_INTERVAL_SECS` setting

There is now one way the list gets written, and it can't disagree with
`relay_members` after commit.

**Unused deploy config (outside this repo):** hosted deployments that
set `BUZZ_NIP43_RECONCILE_INTERVAL_SECS` can drop it. It is now ignored.
Dashboards or alerts on the four deleted metrics will stop receiving
data.

## Testing

New Postgres tests (`buzz-db`):
- `relay_members::every_membership_write_commits_its_list`: for each
write path, the returned list is the single live kind:13534 and names
exactly the committed members. No-op calls return no list and leave the
live list alone.
- `relay_members::a_failed_list_write_rolls_back_the_membership_change`:
holds the list lock, waits for the join to block on it, cancels that
statement, and checks that the member was not added and the previous
list is still live.
- `relay_members::concurrent_joins_all_land_in_the_list`: 8 concurrent
joins; the final list names all 8.
-
`relay_members::same_second_return_to_an_earlier_membership_writes_a_new_list`:
add, remove, add, remove within a second; every list is newer than the
last and no id repeats.
- `relay_members::owner_transfer_and_list_repair_both_commit` and
`relay_members::owner_transfer_and_member_removal_both_commit`: hold a
repair (list lock) or removal (member row) open, wait until a transfer
blocks behind it, then finish it. Both transactions commit; with `FOR
UPDATE` back in place, one of them fails.
- `community::create_community_with_owner_is_atomic_and_create_only` and
`relay_invite::bounded_claim_exhausts_and_existing_member_retry_does_not_consume`
now also check the list.

Each new test was checked to fail against a mutation of the new code
that brings back the old behavior (details in the thread).

Stacked on #8467. Merge order: #8467, then #8468, then this.

c99872f749 fix(relay): delete the startup NIP-33 d_tag backfill (#8468)
## Summary

Delete the NIP-33 `d_tag` backfill that ran on every relay boot.

On every boot, before the listener opened, the relay ran:

```sql
SELECT DISTINCT community_id FROM events
WHERE kind BETWEEN 30000 AND 39999 AND d_tag IS NULL
```

No index covers `d_tag IS NULL`. The only `d_tag` index is the partial
`idx_events_parameterized`, which is `WHERE d_tag IS NOT NULL`. So this
query scanned every partition of `events`. In production it averaged
about 11s per boot, max 19s
(`buzz_startup_phase_seconds{phase="d_tag_backfill"}`), and found
nothing.

These rows shouldn't exist anymore:
- The backfill was the one-time migration for #246, the change that
added `d_tag`.
- In `crates/buzz-db/src`, every production write path sets the column
for kinds 30000–39999 through `extract_d_tag`: the main insert,
`replaceable.rs`, `channel_members.rs`, `relay_members.rs`, and
`push.rs`. A new source test,
`every_production_event_insert_names_d_tag`, now enforces that.
- The `events` inserts that omit `d_tag` are all test fixtures.

`scripts/backfill-d-tag.sql` is still there as the manual fallback for
any database that predates #246 and somehow never booted a relay since.

### What got simpler

- Removed `Db::backfill_d_tags` and its admission test.
- Removed the source-shape assertion in `observability_source.rs`.
- Removed the `d_tag_backfill` startup phase.
- `StartupStep::ALL` is now a slice, so removing a step no longer means
editing a hand-kept array length.

### Notes

- The `buzz_startup_phase_seconds{phase="d_tag_backfill"}` series stops
reporting.
- **Rebased onto main after #8467 merged.** Both remove a startup phase.
With the fixed-length `ALL` array the two merged cleanly in git into a
17-entry `[Self; 18]`, which doesn't compile. This PR makes `ALL` a
slice.
- **Before merging**, run this read-only query against production and
confirm it returns `0`: `SELECT count(*) FROM events WHERE kind BETWEEN
30000 AND 39999 AND d_tag IS NULL`. It scans every partition, so use a
read replica. If it isn't `0`, run `scripts/backfill-d-tag.sql` first.
The cutover script copies legacy `d_tag` values as-is, so only this
query proves historical data is clean.
- **Self-hosted installs** should run the same check before upgrading.

### Related issue

None found. Companion to #8467, which also targets relay startup time.

### Testing

- New `every_production_event_insert_names_d_tag`
(`crates/buzz-db/tests/observability_source.rs`): every production
`INSERT INTO events` must name `d_tag` in its column list. Dropping
`d_tag` from `push.rs` makes it fail and name the function.
- Runtime E2E against a real relay: boot has no `d_tag_backfill` phase;
kind:30023 replacement via WebSocket and HTTP keeps only the newer
event, an unrelated `d` survives, and an older replay can't win
(confirmed in SQL).
- Stacked on #8467 at `501dfd83`: a fresh two-replica boot runs all
enabled startup phases, with neither `nip43_reconcile` nor
`d_tag_backfill` present. Both replicas pass readiness and return the
same signed message over authenticated HTTP and WebSocket, and outsiders
are denied.
- Blox, at `501dfd83`: `just fmt-check clippy security-review-check
file-size-check` passes. Every `test-unit` step and `just test` pass
except the `buzz-acp` `git_bootstrap` native-git tests, which fail the
same way at base `b6aa5539` on Blox, and one `buzz-agent` catalog timing
test that fails only under full-suite load and passes when run alone.
- `e27139de` adds only a doc comment on
`every_production_event_insert_names_d_tag`, saying which SQL shapes the
text match covers. No code changed, so the results above still apply.

c9e35f8ac7 fix(mobile): restore Solo chats from channel labels (#8466)
Restore Solo chats and project placement on mobile using `buzz.solo`
labels and creator metadata. Invalidate stale channel details when
identity changes so opening and sending preserve refreshed Solo
identity; shared chats retain ordinary sending. New mobile Solo chats
publish the discovery label, and the personal send guard enforces
ownership even when route hints or legacy placement suggest Solo.

The current desktop producer lives in `block/buzz-app`. [Contract
documentation](0201ca0572/docs/solo-mobile-contract.md)
links its production creation call to relay identity generation and
mobile regression coverage. Public metadata fields are documented.

Validation: clean analysis; 3,542 mobile tests (5 skipped), 4 push
checks, and 280 core unit/doc tests passed. Removing the cache fix
reproduces the send failure. Local push hooks were skipped with owner
approval after an unrelated terminal timeout and disk exhaustion; full
local CI is not green. GitHub CI must validate the pushed commit. The
initial build was installed/launched on iPhone; follow-up native and
live cross-client confirmation remain pending.

The ownership regression supplies a valid owned member recipient and
checks the exact rejection. A New chat UI test captures the real signed
kind-9007 command. Both regressions were mutation-verified: removing the
ownership guard or the production creation label causes the
corresponding test to fail.

25bcb791b4 fix(relay): show only legacy channel types to reads that name no channel (#8469)
🤖
## Summary
Every Buzz channel has a **type**, such as an ordinary chat channel
(`stream`), a forum, a DM or a workflow. A client app can only show the
types it was built to understand. This PR makes the relay (the Buzz
server) follow one rule everywhere: **a client sees a channel only if it
knows that channel's type.** #8406 applied this rule to membership
notices. This PR applies it to the reads that list channels without
naming one: the channel list, "channels I belong to", the sidebar's
unread list and artifact lists.

Before, these reads left out one type by name: system channels. Now they
return only the four types that every client has always known: `stream`,
`forum`, `dm` and `workflow`. Today the result is the same for every
user, because `system` is the only other type.

### Backward compatibility: old clients stay safe
- A client that was released before a new channel type exists will never
receive channels of that type in its lists. It cannot show such a
channel correctly, so it does not get one.
- Requests that old clients send today return exactly what they returned
before. Nothing changes for them now or when a type is added later.

### Forward compatibility: new types can be added safely
- Before, the rule was a deny list: "everything except `system`". Each
new type would appear in every deployed client by default, unless
someone remembered to update five separate checks in the relay. A missed
check would show the new type to clients that cannot handle it.
- Now the rule is an allow list that is frozen: the four original types.
A new type is hidden by default, with no relay change needed. Clients
that understand it can request it on purpose, the same way current
clients request system channels today. Each new type gets its own
opt-in, so adding a type cannot break clients that are already in use.

## Details
- One frozen list, `buzz_core::channel::LEGACY_CHANNEL_TYPES`.
Membership notices (#8406) now use the same constant, so channel reads
and notices cannot drift apart. The duplicate
`LEGACY_NOTICE_CHANNEL_TYPES` is removed.
- One SQL helper, `legacy_channel_type_sql`, builds `channel_type IN
('stream', 'forum', 'dm', 'workflow')` from that list. It replaces the
five `<> 'system'` checks:
- `get_accessible_channel_ids` (both halves): the implicit channel scope
of any filter without `#h`, for example kind 39000 channel metadata,
REQ, COUNT and search;
  - `get_accessible_channels`: the channel list;
  - the personal-read sidebar roster;
  - artifact queries.
- A filter that names a channel (`#h`, or `#d` on kinds 39000–39003)
reads it under the ordinary rules, whatever its type: the reader is a
member, or the channel is open. The uncached named-channel lookup,
`get_readable_named_only_channels`, now returns every readable
non-legacy channel with its type, not only system channels. Before, a
non-member could not read an open later-type channel, and `#d` read
nothing. Workflow run reads and thread windows use the same lookup.
- The relay keeps each named channel in the scope of the filter that
names it only. This also holds when it re-checks membership for a named
channel that the cache lacks.
- The opt-in to system channels (`#t:["system"]` or `#P` on kinds
39000–39003) adds readable **system** channels only. It never adds a
channel of another type, even one that a sibling filter in the same
request names. The relay scope type `NamedOnlyChannels` keeps the type
with each channel, so the opt-in can tell them apart.
- NIP-CL and NOSTR.md state the rule.

### Related issue
Follows #8406 (the same rule for membership notices).

### Testing
New Postgres tests use a scratch database with a `future_type` value
added to `channel_type`, as a later migration would add one:
- `reads_that_name_no_channel_leave_out_a_type_added_later`: the channel
scope, the channel list and the sidebar roster leave out the later type
and keep the legacy types.
- `artifacts_of_a_later_channel_type_are_read_only_by_name`: artifact
current and history queries and counts without `#h` leave out the later
type. With `#h` naming the channel, they return it.
- `channels_of_a_later_type_are_read_only_by_name`: production read
paths (WS REQ, WS COUNT, HTTP `/query` and `/count`). A member reads a
private later-type channel and anyone reads an open one, by `#h` and by
`#d`; an outsider cannot read the private one; a read that names no
channel returns neither. In one request, a filter that names the channel
plus a `#P` or `#t:["system", <label>]` sibling: the sibling does not
get it.
- `a_named_channel_of_a_later_type_stays_in_its_named_filter`: the
membership re-check for a channel joined mid-request, with an unnamed
sibling and a `#P` sibling. Only the naming filter gets the channel.

Each test fails when its predicate goes back to `<> 'system'`, when the
named lookup loads only `system`, or when the opt-in adds every
named-only channel. The #8406 notice tests and the system channel
Postgres tests pass on this branch.

e6c56ee5ee fix(relay): take NIP-43 snapshot reconcile off the startup path (#8467)
## Summary

Before the relay opened its listener, it reconciled the NIP-43
membership snapshot for every active community. Each community costs two
writer round trips, one after the other. On a production deployment with
about 80k communities, this one step averaged 174s of a roughly 180s
boot (max 324s). Pods in an availability zone farther from the writer
took 3–4× longer than pods in the writer's zone.

The step doesn't need to block startup. The snapshots live in the shared
database, and the replicas that are already running serve the same
snapshots. A new replica has nothing of its own to repair before it
serves. The sweep before bind did the same work as the background
maintenance sweep; only the metric labels differed.

This PR:

- Removes the NIP-43 sweep that ran before bind.
- Moves the background loop into
`side_effects::spawn_nip43_membership_reconciler`. Its first sweep now
runs as soon as the task starts. Before, the loop skipped its first
tick, so the first maintenance sweep waited a full
`BUZZ_NIP43_RECONCILE_INTERVAL_SECS`.
- Runs that loop on one replica only. The replica holding the
`NIP43_RECONCILE_LOCK_KEY` session advisory lock sweeps; the others
retry the lock every `NIP43_STANDBY_RETRY` (5s, capped at the interval).
This reuses the usage-metrics leader lease (a detached Postgres
session), renamed from `UsageMetricsLeader`/`try_lock_usage_metrics` to
the generic `SessionLeader`/`try_lock_session_leader`.
- Waits a full interval after each sweep (sleep after sweep), so a sweep
longer than the interval never runs straight into the next one.
- `reconcile_nip43_membership_snapshots` is now the only entry point and
keeps its original signature (`-> Result<usize>`). It's no longer
deprecated.

### What got simpler

Deleted:

- `Nip43ReconciliationPurpose` (the `Bootstrap`/`Maintenance` purposes)
and `reconcile_nip43_membership_snapshots_with_purpose`
- `Db::bootstrap_community_hosts` and
`Db::nip43_membership_snapshot_needs_reconciliation_for_bootstrap`
- The startup progress log (`NIP-43 startup reconciliation progress`,
`nip43_progress_due`) and its test
- The `nip43_reconcile` startup phase: `StartupStep::ALL` goes from 19
to 18 steps

The leader lock reuses the existing usage-metrics lease rather than
adding a second leader primitive. `StorageAccountingLeader` is still a
near-duplicate of it; folding that in is left as identified debt.

### Trade-offs

- **Repair before serving.** A newly started replica no longer
guarantees it has repaired stale snapshots before serving. The running
fleet doesn't guarantee that today either: the background sweep is what
repairs drift, and the leader starts it as soon as it takes the lock.
- **Rollout load.** Before, every replica swept before binding, and
every replica also ran the background loop. Now there is one sweeper in
steady state, so writer load from this job drops from one sweep per
replica to one per deployment, and rollouts no longer stack boot sweeps.
Standbys add one lock attempt every 5s each.
- **Leader handoff.** When the leader's process exits (including
SIGKILL), its connection closes, Postgres releases the session lock, and
a standby retries the lock at least every `NIP43_STANDBY_RETRY` (5s) and
sweeps as soon as it gets it. Each attempt also waits for a writer
connection, so under database pressure takeover can take longer than 5s.
Before this, a standby waited a full interval (3600s in production), so
after a rollout replaced the leader nothing swept for up to an hour. If
the leader is lost with its host or network instead, the lock is held
until the database server's TCP keepalive drops the session, and nobody
sweeps meanwhile. The usage-metrics leader already has the same
exposure. The lease is checked only between sweeps, so a leader that
loses its session mid-sweep finishes that sweep while the new leader
starts one; the per-community publication lock keeps that overlap safe.
- **Snapshot window.** A missing or stale kind:13534 snapshot is served
until the leader's sweep reaches that community; before, a booting
replica blocked until it was repaired. Admission reads canonical
`relay_members`, so this window doesn't change who's admitted. It does
affect clients that read the snapshot: desktop onboarding shows the
membership-denied page to a member missing from it, the desktop/mobile
member lists and join alerts lag, and desktop mesh discovery keeps its
existing allowlist when the snapshot is missing. In production the
inline publications that keep it current have not failed since
2026-10-07, and the sweep repaired no snapshots in the last 30 days.
- **Dashboards and alerts.** The
`buzz_startup_phase_seconds{phase="nip43_reconcile"}` series stops
reporting. Anything charting or alerting on it should move to the
sweep's existing counters
(`buzz_nip43_membership_reconciliations_total`,
`buzz_nip43_membership_reconciliation_failures_total`).

### Related issue

None found.

### Merge order

#8468 is stacked on this PR. Both remove a startup phase, and with the
old fixed-length `StartupStep::ALL` array, merging both would have built
a 17-entry `[Self; 18]` that doesn't compile. Merge this PR first; #8468
makes `ALL` a slice.

### Testing

- `background_reconciler_sweeps_immediately` (private scratch database):
spawns the production reconciler with a 24h interval and 24h standby
retry, and requires the first sweep to publish a missing snapshot. Fails
if the skipped first tick is restored.
- `background_reconciler_standby_takes_over_on_short_retry` (private
scratch database): with a 24h interval and 100ms standby retry, nothing
publishes while another session holds the leader lock; once it's
released the standby must publish within 10s. Fails if the standby
sleeps the full interval again (checked by reverting that line).
- `test_usage_metrics_lock_has_single_owner_and_releases_on_drop` covers
the renamed lease.
- `maintenance_sweep_skips_archived_and_deleted_communities` now calls
the single entry point.
- Runtime E2E at `574b28b3`: two real relays sharing one database, 3600s
sweep interval, production 5s standby retry. While the leader was alive,
the standby made only lock attempts (no sweep or snapshot-comparison
reads). SIGKILL of the actual lock holder, 3/3 trials: the survivor took
the lock in 4.81–4.86s and repaired the snapshot within 10ms after that.
Both replicas served authenticated reads while the initial publication
was stalled.
- Blox, at `574b28b3`: `just fmt-check clippy security-review-check
file-size-check` passes. Every `test-unit` step and `just test` (118
suites) passes except the `buzz-acp` `git_bootstrap` native-git tests,
which fail the same way at base `b6aa5539` on Blox (environment, not
this change).

6e6173acd5 test(buzz-db): fix two PostgreSQL-lane timing flakes (#8472)
## Summary

Two timing flakes in the PostgreSQL lane, one fix each.

### Deletion lock order

`abort_serializes_before_fence_without_deadlock` failed on main ([run
39330176879](https://github.com/block/buzz/actions/runs/39330176879)):
`post-lock lease verification rejects aborted request: 1`.

The test slept 50ms and assumed `abort` had queued on the community
advisory lock by then. On a slow runner, `fence` queued first, won the
lock, and succeeded.

The test now waits until `pg_locks` shows each contender waiting on that
community's lock, `abort` first and then `fence`. Postgres grants queued
advisory locks in arrival order, so `abort` always wins. The sleeps and
their timing guess are gone.

### Saturated-reader fixture

`routed_fallback_spends_one_acquire_budget_when_aurora_cache_is_cold`
failed this PR's first run ([run
39335038111](https://github.com/block/buzz/actions/runs/39335038111)):
`establish the reader's sole connection: PoolTimedOut`. Setup opens the
reader's only connection through the production lazy pool, which has a
150ms acquire timeout. On a loaded runner that first connect took
longer, so the test failed before reaching the budget it measures. Setup
now retries on `PoolTimedOut` within 5s. The pool and its 150ms budget
are unchanged for the routed read under test.

Test-only. Production code is unchanged.

## Validation

- Deletion test against an isolated local Postgres 17 database: 40/40
passes. Saturated-reader test: 15/15.
- `cargo fmt --check`, `cargo clippy -p buzz-db --tests -D warnings`,
pre-push Rust unit tests: pass.
- Three other `store::deletion::postgres_tests` fail locally on
unmodified `main` as well (local environment). CI's PostgreSQL lane is
the authoritative check for them.

b6aa5539e3 feat(mobile): account onboarding, key recovery and hosted reconnect (#8375)
## Behavior

Adds optional mobile Builderlab sign-in, identity backup/recovery,
community discovery/creation, and account-aware reconnect. **Builderlab
features are disabled by default:** when `BUZZ_AUTH_DOMAINS` is unset or
empty, account login, creation, backup/recovery, reconnect prompts, and
background account restoration are hidden/disabled. QR/code pairing,
links, and invites retain Nostr-only entry. Saved account state is
retained for later opt-in.


`--dart-define=BUZZ_AUTH_DOMAINS=communities.buzz.xyz,communities.public.builderlabstaging.xyz`
opts those DNS domains and their subdomains into required account setup.
The same policy gates pairing, deep links, durable community admission,
and reconnect. A nonempty list enables Builderlab features;
`BUZZ_BUILDERLAB_URL` alone does not. Enabled flows still require their
backend services. Existing Nostr relay authentication remains mandatory.

`BUZZ_HOSTED_RELAY_AUTH=true` enables scoped relay assertions and
reconnect prompts only for configured authentication domains. Configure
assertion issuance and each community's issuer binding before enabling
assertions; enable relay enforcement last. Account credentials stay at
Builderlab. Wrong-account recovery preserves keys; failed writes are not
replayed; authentication is bounded by request deadlines.

Hosted flows preserve keys across cancellation/restart, reconcile
interrupted creation/invitation acceptance, and support manual nsec file
import/export. Account identities are scoped to backend and
authenticated subject; reusing an existing local key for an unbound
account requires an explicit selection. Recovery reconciles the
advertised and recovered inventories before automatic selection.
Successful self-hosted admission retires its pending key, and iOS
startup removes interrupted export files. Adds authenticated relay `GET
/operator/communities/joined` for the companion Builderlab membership
endpoint.

## Validation

- Follow-up review repair at `66a12ac92`: self-hosted entry presents
readable choices and import despite incomplete enumeration, while
generation still requires a complete empty inventory; explicit selection
uses exact-key lookup. Consuming a value-equal duplicate now advances
dispatch. Reconnect requires an existing account binding or a
subject-scoped backup receipt before signing an assertion, and pins the
subject inside the serialized account request. An empty different
account is refused without sending key proof. Focused checks: configured
domains 58 passed; default 49 passed, 9 hosted-only skips. Separate
isolated mutations fail the incomplete-inventory sheet, exact-key reuse,
duplicate dispatch and reconnect journeys (including an
empty-account-only bypass); restored controls pass. Evidence uses
synthetic storage/network boundaries, not physical Android or live
backend association. All mandatory commit/push hooks passed; fresh
GitHub CI is pending.

- Bounded review repair at `d3cc0003f`: incomplete secure-storage
enumeration now blocks automatic identity generation while explicit
known-key reads retain their fallback; declined/failed onboarding links
release the queue; HTTP 429/5xx keeps Retry regardless of response
encoding. Default app-gate coverage exercises a bind link followed by
ordinary community entry. Focused checks: configured domains 47 passed;
default 38 passed, 9 hosted-only skips. Removing the three production
fixes in an isolated source/Git/build copy fails the
identity-resolution, declined/failed queue, and Retry journey
assertions; clean and restored controls pass. Storage and HTTP failures
are synthetic; physical Android and live outage behavior were not
exercised. Published after all mandatory commit/push hooks passed
(mobile analysis/tests, branch-skew and file-size gates); fresh GitHub
CI remains pending.

- Existing whole-PR source review cleared the reconnect defects at
`fb15d5b82`.
- Domain-policy increment: focused environment, entry, app-gate, pairing
and onboarding journeys pass with empty and configured domains. Existing
pairing provider/page tests pass. Changed Dart files analyze cleanly.
- Isolated source/Git/build mutation: forcing paired credentials through
hosted login fails the default-build journey; clean and restored
controls pass. CI now runs configured-domain journeys in addition to the
default-build suite.
- Integrated main through `5b433d929` at `0067c069c`, including its
pinned Flutter upgrade. Preserved the PR welcome UI with the updated
transition API and added Material surfaces around onboarding
selection/consent rows. Focused post-merge runs pass in both
configurations; all mandatory local push gates passed (mobile
analysis/tests, Rust tests, desktop-native checks, branch-skew and
file-size checks).

- Merge-review repair at `a315bce11`: focused identity/storage/admission
and widget journeys pass, including account switching with an empty or
already-bound second account, explicit reuse, and self-hosted
removal/rejoin with another key. Default-domain journeys pass too
(hosted-only cases intentionally skip there).
- Isolated source/Git/build mutation checks: bypassing account scoping,
reuse consent, pending-key retirement, or recovery inventory
reconciliation fails the relevant journey/invariant assertions; clean
and restored controls pass.
- Native `RunnerTests/IdentityFilePluginTests`: both tests pass on the
iPhone 18 Pro iOS 27 simulator with an isolated app identifier. At
`24a0dcaac`, the picker journey seeds residue in Library/Caches,
matching path_provider_foundation, and verifies plugin startup removes
it while preserving an unrelated file. The earlier tmp-only fixture did
not exercise the actual export location. This is synthetic native
cleanup/picker evidence, not a real terminated-share or live account
round trip.

- Follow-up: Caches and tmp cleanup; fallback to individually known
identity slots when Android bulk enumeration fails; explicit replacement
of a refused self-hosted key preserves its original before swapping the
retry slot. Configured-domain journeys/invariants: 34 passed; default:
31 passed, 3 hosted-only skips. Isolated enumeration/retry mutations
fail with passing controls. Bulk-read fallback preserves but cannot
enumerate arbitrary other-account slots until bulk reads recover.

- Configured-domain CI exposed a stale pairing-status assertion after
account scoping. The repaired test checks the admission mismatch,
preserved account/transfer keys, and no admitted community. The
configured-domain CI selection passes locally (56 tests); removing the
production mismatch guard fails the updated test, with clean/restored
controls passing. This is synthetic coordinator evidence, not physical
QR acceptance.

- Final review repair (`40e1e6101`): native iOS export creation uses
atomic complete file protection; normal and restart cleanup remain.
Account/policy/claim HTTP uses one 30-second total deadline with request
abort and body cancellation. Removed the unrelated NIP-FA spec edit.
- Focused account/admission/export tests: 25 pass; configured-domain
account/admission/onboarding journeys: 33 pass. Isolated deadline and
native-dispatch mutations fail, with passing clean/restored controls.
Native export/picker tests: 2 pass on iOS 27 simulator. The real
file-protection attribute assertion is physical-device-only because
simulator provides no Data Protection attribute; locked-device
protection and interrupted real sharing have not been observed.

- Opt-in UI: configured-domain CI selection passes (57 tests); default
selection passes (7 tests, 10 hosted-only skips); URL-only plus
whitespace/empty domains passes (6 tests, 9 hosted-only skips). Changed
Dart files analyze cleanly. Independent mutations that unconditionally
initialize the coordinator in the app gate, welcome entry, or link form
fail the default journey; clean/restored controls pass.
- Native welcome screens exercised on iPhone 18 Pro / iOS 27 simulator
in default and configured builds: default exposes community link / QR /
pairing code only; configured build additionally exposes Builderlab
connection and community creation. No live hosted login was exercised in
this check.

- Delivery at `e48fe73a9`: all mandatory push hooks passed (full mobile
analysis/tests, Rust tests, desktop-native checks, branch and file-size
checks). GitHub checks had not yet populated at the immediate post-push
snapshot.

## Review disposition

| Feedback | Disposition |
| --- | --- |
| Explicit self-hosted entry under unreadable inventory, duplicate
invite dispatch, reconnect cross-account binding
([entry](https://github.com/block/buzz/pull/8375#discussion_r4318421622),
[queue](https://github.com/block/buzz/pull/8375#discussion_r4318421640),
[reconnect](https://github.com/block/buzz/pull/8375#discussion_r4318455512))
| Repaired at `66a12ac92`; evidence above. Reconnect refuses unproven
ownership rather than silently establishing a binding. |
| Incomplete Android identity inventory, stranded deep-link queue,
transient HTTP retry classification
([review](https://github.com/block/buzz/pull/8375#pullrequestreview-5576864143))
| All three repaired in `d3cc0003f`; focused journeys and isolated
mutation evidence above. |
| Account cross-link, incomplete recovery inventory, committed invite
checkpoint, pending local key retirement/replacement | Repaired in the
preceding commits; journey and mutation evidence above. |
| iOS interrupted key export
([review](https://github.com/block/buzz/pull/8375#pullrequestreview-5575253252))
| Native cleanup plus complete protection at creation implemented.
Physical-device lock and real interrupted sharing acceptance remains
pending. |
| Trickle responses bypass idle timeout; unrelated NIP-FA edit
([review](https://github.com/block/buzz/pull/8375#pullrequestreview-5575764556))
| Total request deadline/abort implemented; spec edit removed. |
| Production domains rejected | Ordinary entry now needs no Builderlab
configuration. Opt-in account-required domains must still use supported
community mappings. |
| Lost Android Keystore recovery | Backup exclusions prevent the
reviewed stale-restore scenario; genuine key loss still has no in-app
recovery/reset and remains deferred. |
| Native secp256k1 dependency question | Obsolete against the current
base: upstream C integration landed in #8398; no package diff remains
here. |
| Operator membership endpoint contract | Documentation now states the
operator chooses the pubkey; no end-user session binding is implied.
Additional handler-level coverage is optional follow-up. |
| Optional Android partial document cleanup/activity retention; local
work after backup cancellation | Follow-up hardening, not claimed
implemented. Cancellation prevents remote backup upload. |
| Semgrep crypto inventory notices | Informational inventory, not
demonstrated defects. |

## Remaining draft gates

Native QR/browser-return acceptance remains unverified for this
revision. Optional Builderlab onboarding still needs backend
backup-status and joined-community routes, recovery
policy/configuration, and real backup/recovery/reconnect acceptance. The
empty-domain build removes these services as prerequisites for ordinary
pairing; it does not make the optional hosted flows backend-ready. Human
acceptance and current CI are still required before merge.



Review dispositions retained: production auth-domain configuration must
use supported community mappings; enabling `builderlab.xyz` does not add
support for `buzz.block.builderlab.xyz`. Recovery after genuinely losing
an Android Keystore key remains a follow-up, not a newly implemented
capability.


Human acceptance steps: build once without `BUZZ_AUTH_DOMAINS`
(including with a previously saved account) and confirm no Builderlab
controls/restoration while ordinary link and QR/code entry work. Build
with supported domains and confirm connection/creation appear; exercise
browser return and live backup/recovery/reconnect. On physical iOS,
exercise export and interrupted sharing/locked-device protection. Record
results before marking review complete.

cc6336d985 feat(relay): tag every membership notice with its channel type (#8406)
🤖
## Summary
- When someone is added to or removed from a system channel, the relay
now sends them the usual "you were added / removed" notice. Before, it
sent nothing, so a client could learn about a new system channel only by
rereading every channel.
- **A client sees a notice only if it knows the channel's type.** Every
membership notice now carries its channel type. Clients that do not send
`#t` (every client today) see only the types that existed before system
channels, so they see no change. A type that Buzz adds later is hidden
from them by default.
- The notices are stored like every other membership notice, so a client
that was offline can catch up with `since` instead of rereading all its
channels.

## Details
- Every kind:44100 (added) and kind:44101 (removed) notice now carries
`["t", <channel_type>]`, for example `["t","stream"]` or
`["t","system"]`.
- **One place reads the channel type:** `emit_membership_notification`
in `side_effects.rs`, where the relay signs the notice. A channel's type
is set when it is created and no code path changes it, so the tag stays
correct. If the channel row is missing, the relay sends no notice rather
than an untagged one.
- **The rule (NIP-CL):**
- a filter with `#t` matches a notice only when the notice's type is one
of its `#t` values;
- a filter without `#t` matches only the **legacy types**: `stream`,
`forum`, `dm`, `workflow`. This list is frozen
(`LEGACY_NOTICE_CHANNEL_TYPES`), so a new type never joins it;
- a notice without a `t` tag was stored before this change. It is always
a legacy type, so the relay treats it as one, and replay across the
upgrade stays complete.
- **Fails closed.** The rule lives in two shared places, and both
default to the legacy types. A read path that is not updated behaves as
it does today:
- `filters_match` / `notice_visible` (buzz-core). Live fan-out, the REQ
history post-filter, COUNT, the HTTP bridge and push all match through
it.
- `EventQuery::notice_channel_types` (buzz-db). Its SQL keeps only
visible notices before `LIMIT`, so page limits and COUNT stay exact.
`None` means legacy types. Only `filter_to_query_params` sets it, from
the filter's `#t`.
- A client that knows every current type sends one filter:
`{"kinds":[44100,44101],"#p":[<me>],"#t":["stream","forum","dm","workflow","system"]}`.
NIP-CL and NOSTR.md describe this.
- **Only the target receives a notice.** A notice names the target, the
channel and who made the change, and the relay signs it, so knowing its
id is not permission to read it. 44100/44101 are now in
`RESULT_GATED_KINDS`, the one list used by the `ids` exemption check,
the per-result reader check (WS and HTTP history, push), live fan-out
(same pod and Redis) and COUNT. This also closes the same id lookup for
ordinary channels' notices.
- No migration: 44100/44101 are already excluded from search indexing.

## Testing
- `buzz-core`: a table test covers untagged, `stream`, `system` and a
future type against filters without `#t`, with `#t` for one type, and
with `#t` for every type. Other kinds keep the plain `#t` match.
- Postgres tests (`system_channel_postgres_tests.rs`): live fan-out, REQ
history, COUNT and the HTTP bridge, for a filter without `#t`, a
`#t:["system"]` filter and an all-types filter; an untagged legacy
notice; a non-target with an `ids` filter on each path; and a raw
`EventQuery` that does not set the field.
- I broke each part on purpose and the tests failed: no type tag on the
notice, no rule in `filters_match`, no SQL rule, and no untagged clause
in the SQL.
- End to end: I built a relay container from f24f8e7ba and ran
buzz-app's `container-relay.e2e.test.ts` (block/buzz-app#1290) against
it. The live system channel test passed 5 of 5 runs.

Paired client change: block/buzz-app#1290. It works unchanged against
this relay.

91e7b469b8 fix(relay): wait for the peer's Close before dropping any WebSocket (#8426)
🤖 A NIP-42 login refused for a NIP-FI key mismatch could reach the
client as an abnormal close (`1006`, no reason) instead of the `NOTICE
"restricted: authorization denied"` followed by close `1008` that every
other authorization denial produces.

The relay did write the NOTICE and the `1008` Close, but the connection
task dropped TCP as soon as the writer finished, before the peer
finished the close handshake. The client could then lose frames it
hadn't read yet. It depends on timing, so it showed up intermittently
and is not specific to key pairing.

## Relay route

- `recv_loop` now hands back the read half even while a frame handler is
still running. Frames are handled one at a time while the connection is
live. Once it is cancelled, an in-flight handler (for example a Nostr
`CLOSE` waiting on the subscription lock behind a REQ stuck in Redis) is
spawned to finish instead of holding the reader. It is never dropped
partway, so subscription retirement stays atomic, and cleanup joins it
before the expiry barrier and application cleanup.
- As soon as the writer finishes, `await_client_close` keeps the
transport open until the client's Close arrives or the stream ends. It
runs concurrently with joining the heartbeat, auth-timeout, expiry and
auth-cancel tasks and the connection's application cleanup
(subscriptions released, registry entry removed, presence cleared).
Cleanup never waits on the peer, so a nonresponsive client cannot delay
registry counts, presence or `has_admitted_connection`. The socket never
waits on cleanup, so a stalled Redis (the pool has no wait timeout) or
an expiry join blocked on its quiescence barrier cannot hold the socket
and its file descriptor open past the bounded wait. The
active-connection gauge and the connection permit are released after
both finish.
- The connection permit (`BUZZ_MAX_CONNECTIONS`) is now taken at the
start of `handle_connection`, before the NIP-FI gate and the
community-active bootstrap check, and held through the active handler or
the refusal drain and its bounded wait. Previously a socket in
bootstrap, or refused there, held no permit, so a burst of refusals
could open sockets beyond the limit. Over the limit, the socket is still
dropped with no frames. `buzz_ws_connections_active` still counts only
connections that reached the active handler.

## Huddle-audio route

- The relay and audio bootstrap drains share one bounded helper. A
socket refused before admission waits after its community registry entry
is released.
- Every exit of the audio handler gets the bounded peer wait. Exits
whose cleanup follows their terminal frames (`room_full`, `room_ended`,
version mismatch, archived channel, owner rejection or unreachable,
failed commit confirmation) and the normal teardown hand the socket to a
background task that waits for the client's Close, so lease releases,
`48102` writes and room archiving on Postgres and Redis never hold the
socket open. The remaining exits send their frames last, and
`handle_active_audio_connection` waits once they return. The wrapper
joins the background task before returning, so the audio connection
permit is held until the socket ends, as on the relay route.
- Audio error exits now follow their existing JSON error with a Close
frame:

  | Exit | Close code |
  | --- | --- |
  | `huddle_relay_draining` | `1012` service restart |
| `join_rejected` (owner resolution failed), `huddle_owner_unreachable`,
failed channel lookup | `1011` internal error |
| `huddle_audio_unavailable`, `unsupported_version`, `upgrade_required`,
`room_full`, `room_ended`, archived channel, owner rejection, NIP-FI
authorization denial | `1008` policy |

Audio login failures and authorization refusals outside NIP-FI
`authorization_denied` still send only their existing error frame, then
get the bounded wait.
- The audio read half is an enum, so the hand-off has no `expect()` that
can panic.

## Timing

- The peer wait is bounded by `WS_TERMINAL_FLUSH_TIMEOUT` (1s), and
drains to end-of-stream so a client-initiated Close gets its reply. The
terminal writer flush has its own 1s budget, so the worst case for
terminal transport work is about 2s per refused or closed socket.
- Terminal frame writes (`flush_terminal_frames`,
`send_exit_frames_bounded`) still give up on the first failure, but a
failed or timed-out send is now logged at `debug` instead of being
discarded.
- The graceful-shutdown comment in `main.rs` now describes per-stage
budgets (restart jitter, restart-Close acknowledgement, terminal flush,
peer wait) rather than a per-socket total. The 30s hard drain bounds
every socket, and the 35s process shutdown budget fits within the
chart's 60s `terminationGracePeriodSeconds`.

## Tests

Real-socket tests in the infra-free relay lane of `just test-unit` and
`scripts/run-tests.sh` unless marked PostgreSQL:

- The key-mismatch login and a session-expiry denial (as a control) both
assert NOTICE then `1008` / `authorization denied` on the wire.
- A raw-TCP client that never answers Close: the relay holds the socket
for at least the bounded wait, has deregistered the connection by the
time the socket ends, and ends it on its own under a 10s watchdog.
- A raw-TCP client that withholds its Close until the connection has
deregistered: the relay ends the socket in under the 1s cap, which fails
if cleanup waits on the peer.
- A raw-TCP client that never answers while final cleanup is stalled at
a test pause point: the socket still ends after the bounded wait.
- A raw-TCP client that never answers Close on the relay bootstrap
drain, the audio bootstrap drain and an early audio-handler exit: the
relay holds each socket for the bounded wait.
- On the relay route with a one-slot budget through the real
`handle_connection`: a refused bootstrap holds the slot until its socket
ends, and a bootstrap stalled on the community check already holds the
slot before the AUTH challenge is sent.
- An established relay session whose reader is blocked in a Nostr
`CLOSE` handler on a held subscription lock when the session expires:
the socket ends within the bounded wait while the lock is held, and
cleanup completes with the subscription retired once it is released.
- An established relay session whose expiry task is stalled behind a
held session effect permit: the socket still ends within the bounded
wait.
- PostgreSQL: an established audio session whose teardown is stalled
after its Close, and a stalled archived-channel exit, both end within
the bounded wait from the hand-off.
- PostgreSQL: a fast refusal (unsupported protocol version) through the
real `handle_audio_connection` with a one-slot permit budget keeps the
permit taken until that socket ends.
- PostgreSQL: `huddle_audio_unavailable` sends its error and then Close
`1008` as the very next frame.

af7979e1ca test(auth): read the clock once in NIP-FI until test (#8457)
🤖 The exact NIP-FI assertion-lifetime boundary test could fail when its
JWT helper read the clock, then ES256 signing crossed a whole-second
boundary. The token's `until` claim could land one second beyond the
verifier's `now + skew + maximum_age` ceiling even though both were
intended to use the same test instant.

This changes the test helper to accept a captured instant and uses that
instant for both the JWT time claims and `verify_at`. The boundary
remains strict: `now + 3630s` is accepted and `now + 3631s` is rejected.
No production code changes.

5b433d9292 feat(relay): resolve NIP-FI issuer bindings from the database (#8377)
Stack: #8372 (merged) → this PR → #8399 → #8401

Makes relay login checks read the per-community NIP-FI issuer bindings
that #8372 stores. Without this, the relay can't keep up with bb-public,
where new communities are created at every signup and a static
`BUZZ_NIP_FI_COMMUNITIES` list won't do.

**Source switch.** `BUZZ_NIP_FI_COMMUNITY_SOURCE=database` resolves each
community's trusted issuers from `community_nip_fi_issuers`, filtered by
the issuer registry, instead of the static list. Each community gets its
own policy ID: the base ID no longer hashes every community audience,
and the final ID hashes the base plus this community's audience, so
policy IDs change once (see `docs/operator-nip-fi-bindings.md`).
`Config::from_env` refuses to start, in every mode, on an unknown
source, on `database` together with `BUZZ_NIP_FI_COMMUNITIES`, and on
`database` without `BUZZ_NIP_FI_PROVISION_BINDING`.
`BUZZ_NIP_FI_RESOLVER_*` and `BUZZ_NIP_FI_SNAPSHOT_*` are validated in
every mode, so a bad value fails the deploy that sets it. In `off` mode
no resolver is built and no snapshot is loaded.

**Resolver (`nip_fi_resolver.rs`).**
- **Snapshot:** each pod loads every binding into memory, capped at
`BUZZ_NIP_FI_SNAPSHOT_MAX_ROWS` (going over is a failed load). It
refreshes every 30 s, start to start, with jitter that only shortens the
delay and backoff after failures. Each attempt is limited by
`BUZZ_NIP_FI_SNAPSHOT_REFRESH_TIMEOUT_MS`, which must be shorter than
the interval. A refresh whose deadline passes before it publishes
publishes nothing. The old snapshot is dropped off the runtime.
- **Freshness:** a host in a snapshot loaded under two minutes ago is
answered from memory. Any other host, and every host once the snapshot
is stale, goes to a live lookup. Every answer carries a deadline two
minutes after the read behind it started, and WS, HTTP and audio recheck
it just before admitting.
- **Live lookups:** bounded and single-flight. In-flight lookups are
capped by `BUZZ_NIP_FI_RESOLVER_MAX_INFLIGHT` (default 8, clamped below
the database pool size), and the pending hosts and their waiters have
fixed caps. Positive answers are used for that admission only. A "not
found" is cached for 5 s, up to
`BUZZ_NIP_FI_RESOLVER_NEGATIVE_CACHE_MAX` hosts, and only when no
snapshot was published and no binding was created while it ran. A lookup
that panics still leaves the pending map.
- **Removal:** a removed binding stops admitting new connections within
30 s plus the refresh timeout (40 s by default) while refreshes succeed,
and within two minutes of the last good load while they fail. Open
WebSocket sessions are not rechecked when a binding is removed; they end
at their own session deadline.

**Shadow mode** resolves through the same path as enforce, including the
database lookup and the freshness rules. It keeps the resolved binding's
deadline and checks it at the same point as enforce; a binding that goes
stale during the tenant lookup is recorded as `stage=deadline,
outcome=unavailable`, without changing the legacy response or closing
the socket. With `source=database` its `community` metric label is only
`bound` or `unmapped`; with `source=env` it keeps the existing
per-community audience label, so current shadow dashboards are
unchanged. Each request resolves its Host once: the router guard's
resolution, failures included, is reused by shadow recording and
admission.

**Provisioning.** Both operator provisioning paths drop this pod's
cached "not found" for the new host after a commit that bound issuers,
so the creator's first login looks it up.

**Startup and readiness.** With `source=database` and a mode other than
`off`, the first snapshot loads before any listener binds, under its own
startup phase `nip_fi_snapshot_load`. A failed load exits non-zero, so a
pod is never ready without a snapshot. **Operational consequence:** boot
already fails when the database is unreachable; what is new is that a
snapshot over `BUZZ_NIP_FI_SNAPSHOT_MAX_ROWS` or a load past its timeout
also crash-loops new pods. After two minutes the old pods' snapshots go
stale and most logins fall through to the 8-slot live lookup, which
sheds the rest with 503. The way out is raising the cap or timeout, or
`mode=off`.

**Metrics.** `buzz_nip_fi_binding_snapshot_*` covers loads, failures,
rows and freshness.
`buzz_nip_fi_binding_snapshot_loaded_timestamp_seconds` is written on
every refresh attempt, so alert on `time() - x > 120` together with
`absent(x)`. `buzz_nip_fi_binding_snapshot_rows` against
`buzz_nip_fi_binding_snapshot_max_rows` gives the headroom to the row
cap. `buzz_nip_fi_resolver_*` covers live lookups and the negative
cache. The env vars and alerts are documented in `.env.example`, the
chart README and `docs/operator-nip-fi-bindings.md`, which also has the
staged off → shadow → enforce rollout for `source=database` with
go/no-go signals at each step, and the over-cap and load-timeout failure
modes with their ways out.

**Regression coverage.** Router-level tests run the database resolver
through the real `build_router` for root WS, audio and protected HTTP,
in enforce and shadow mode. Over PostgreSQL and Redis, two pods using
the env community source (two exact bindings) replay assertions retained
from before a disconnect through a real root NIP-42 session, the audio
deny-set check and signed NIP-98 requests: they are denied on both pods,
and a root session upgraded before the disconnect is refused by the
post-registration deny-set check. Postgres tests in `buzz-db` check that
archived and quiescing communities, and issuers missing from the
registry, never reach the snapshot or the live lookup. Process-level
`boot_lifecycle` tests spawn the real relay with `source=database`: an
over-cap or timed-out startup load exits non-zero with no health
listener bound, and a loadable snapshot lets readiness turn ready.

305fb7b5cd fix(push-gateway): request default notification sound (#8431)
Push banners arrive silently because the gateway's fixed APNs body never
requests a sound, even though the iOS app requests sound permission. Add
`aps.sound: "default"` to that constant so ordinary alerts request the
system sound even if the notification extension is not invoked. Preserve
the existing alert text, mutable-content flag, and class-blind,
content-free delivery contract; synchronize its normative specification
and executable models.

Companion client workaround:
[#8429](https://github.com/block/buzz/pull/8429). This gateway change
also covers the original-payload fallback and requires no mobile source
change. Sound remains subject to iOS settings and authorization. It does
not bypass Focus or Silent Mode, select critical alerts, or guarantee
vibration. Every public-profile wake requests the same sound, including
generic/restricted fallback banners.

### Validation

- Extended the real HTTP transport test: reproduced missing sound
(`null` versus `default`) before the fix, then passed with the fix. All
79 runnable gateway library tests pass; 17 infrastructure/manual tests
remain ignored.
- Added a guard against drift between the emitted bytes, NIP-PL, and
both formal models. Fixed-payload and stateful-delivery models and
mutation checks pass.
- Inspected the 0.24.0 (7) iOS source: sound permission is requested;
ordinary enrichment and restricted fallback copy incoming content. A
macOS UserNotifications probe confirms copy retention, but does not test
iOS Intents or audible device delivery.
- Focused existing native resolver/handoff tests pass (35 tests on
macOS). These cover resolution and fallback behavior, not iOS sound
playback.
- Deployed exact head
[b8a0eb6](b8a0eb6b78)
to the personal dev push gateway (Railway deployment
`b3e52fc8-d1d3-48d7-ae21-1a83c5db2e99`). Verified the dev relay already
routes to that gateway. On an iPhone 12 mini running the existing Buzz
Dev 0.22 (10140), without the client workaround, automation captured the
test banner and Tom confirmed audible sound on October 18.
- Broad local validation reached an unrelated ACP startup-deadline
failure in
`signals_cancel_startup_turn_and_pending_stdin_without_hanging`. No ACP
source or dependency changed, and ACP does not depend on the gateway.
The full local gate is not reported as passing.
- Local desktop pre-push tests passed 3,420 cases but failed two
unchanged agent-discovery checks (a 300 ms subprocess deadline and a
login-shell PATH comparison). Desktop does not depend on the gateway.
Retried publication with only the Rust-suite and desktop-Tauri lanes
excluded under the standing unrelated-failure exception; other hooks
remain enabled.


### Before merge

- [x] Verify a real push banner and audible sound through the dev relay
and candidate dev gateway on an iOS device without the client
workaround.

3ffbfa693c feat(relay): start a channel with its members in one create (#8421)
## What

A kind:9007 can now name the channel's first members with `p` tags.
Those members are added in the same database transaction that creates
the channel. Resending a create whose OK was lost is now accepted
instead of refused.

## Why

Starting a new Solo chat today takes about 6–8 sequential relay round
trips before the first message goes out: create, read, add each agent
(kind:9000), read the roster, then send. With members in the create, a
client can start a chat with its agents as two writes: the create, then
the message as soon as the create is OK.

The resend fix makes the create safe for an outbox to retry. Today an
identical resend after a lost OK is refused with `duplicate: channel
already exists`, so the client can't tell success from a real UUID
collision.

## How

- **buzz-db:** `Db::create_channel_with_event` writes the channel, its
owner, its members (role `member`, `invited_by` = creator) and the 9007
event itself in one transaction. A channel row therefore never exists
without its create event. `create_channel_with_id` is unchanged for its
other callers.
- **Validation** (`side_effects::initial_members` and the
`validate_admin_event` 9007 branch):
  - Each `p` must be a 32-byte hex pubkey.
  - Duplicates and the creator are dropped.
  - At most 32 members.
  - An `h` tag is required when there are members.
- Each member goes through the same `decide_channel_add_policy` check a
kind:9000 uses, so an agent that refuses third-party adds keeps the
whole create out.
- **Side effects:** each initial member gets the same `member_joined`
system message and member-added notification a kind:9000 would post. The
fallback in `handle_create_group` creates a bare channel when the
pre-created row is missing; it announces no members, because it added
none.
- **Resend:** when the UUID is already taken, the same transaction
checks whether this exact event is the stored create.
- If it is, the create is OK'd as `duplicate:` (it is the same signed
create).
- Anything else, including a changed create from the same author, is
refused and writes nothing, so it can never re-run side effects or
announce members.
- A resend that arrives while the first create is still uncommitted
waits on its channel insert. It is confirmed once the first commits, or
creates the channel itself if the first rolled back. Before this, a
resend in that window was refused, and the app then withdrew a chat that
existed.
- **No compensation:** ingest no longer soft-deletes a pre-created
channel when the event insert fails. The rollback covers it.
- **Announcements:** a failed `member_joined` notice for one initial
member is logged at `error` and the loop continues, so the members after
it still get theirs. A resend writes nothing, so nothing would retry
them.

## Compatibility

A 9007 with malformed `p` tags, or more than 32 of them, used to be
accepted with the tags ignored. It is now rejected with `invalid:`. The
relay's own SDK and CLI builders send no `p` tags on 9007.

## Out of scope

- The kind:9000 OK still doesn't prove the membership change committed:
side-effect failures are logged and OK'd, and a duplicate replay skips
side effects. The new path doesn't depend on kind:9000.
- Events in separate HTTP requests are still unordered. Clients send the
first message after the create's OK.

## Tests

`store::channel::postgres_tests` (buzz-db):
- `a_resend_beside_an_open_create_confirms_it_once_committed`: holds a
create open, checks that the resend waits, commits, and expects `Exists
{ resent: true }` with one owner and one member.
- `a_resend_beside_a_failed_create_creates_the_channel`: the same, but
the first create rolls back.
- `a_create_whose_event_fails_leaves_no_channel`: an event the insert
refuses leaves no channel row, and a retry creates the channel.
- `another_create_for_a_taken_channel_writes_nothing`.

Two mutations, each caught: committing the channel before its event
fails the "leaves no channel" test, and looking up the event before the
channel insert waits fails the "confirmed once committed" test.

`handlers/create_with_members_postgres_tests.rs`, all through the real
ingest path:
- `create_adds_its_p_tags_as_members` checks:
  - the roles and the 39002 roster
  - exactly one `member_joined` notice
  - that the agent can post with no separate add
- `create_respects_the_members_add_policy`: an agent with policy
`nobody` gets an `invalid:` rejection, and no channel is created.
- `resending_a_create_confirms_it`:
  - an identical resend is accepted
  - a changed create (from the creator or from someone else) is refused
  - the roster is unchanged and nobody new is announced
- Unit tests for `initial_members`: dedupe, creator excluded, bad hex,
the 32-member cap, and the missing `h` tag.

Each new test was mutation-checked against the change it covers: no
members, no policy check, refuse every resend, and let a changed creator
create through. Each mutation turns its test red.

Agent exercise on a local relay, over `POST /events` the way the app
sends:
- The 9007 with `p` = agent was accepted in 54–97ms (debug build).
- The kind 9 was accepted 12–15ms after the create's OK.
- The agent was in the 39002 roster, and the operator listener delivered
the mention.
- An identical resend came back `duplicate:` (accepted), and a changed
create was refused.

Local suite runs at 10adcf6dd (the transaction fix), on PG14:
- `postgres-test-run.sh -p buzz-relay -p buzz-db`: 28 failures. That is
the same 27 as below, plus `personal_read_frontier_is_monotonic…`, which
hit a statement timeout under load and passes when run alone.
- `cargo test -p buzz-db -p buzz-relay`: the same 6 `api::media`
failures and the flaky `mesh_demo` test.

Earlier local suite runs:
- New tests pass and clippy is clean.
- `postgres-test-run.sh -p buzz-relay -p buzz-db`: 27 failures
(partition maintenance, a huddle links test, a redis boot test), and the
same 27 fail on a96ace4e5.
- `cargo test -p buzz-relay`: 6 `api::media` failures (they need a DB at
the default URL) also fail on base.
- One `api::mesh_demo` test is flaky: it passed 2 of 3 branch runs and
failed once on a timeout.

6286a54321 feat(relay): store per-community NIP-FI issuer bindings (#8372)
Stack: this PR → #8377 → #8399 → #8401

bb-public creates communities all the time, so a hand-edited
`BUZZ_NIP_FI_COMMUNITIES` map can't list them. This PR stores an
explicit NIP-FI issuer allowlist for each community in the database and
writes it when the community is created. Login checks don't read the
table yet; that comes in #8377 together with the database-backed
resolver. Operator steps are in
[`docs/operator-nip-fi-bindings.md`](docs/operator-nip-fi-bindings.md).

**Storage.** Migration `0066_community_nip_fi_issuers` adds
`community_nip_fi_issuers (community_id, issuer, created_at)`, with
primary key `(community_id, issuer)` and the community write fence
attached. The assertion audience is `https://<communities.host>`, so the
table has no `aud` column. Zero rows means no binding. The table is
included in whole-community deletion and purge.

**One bindable rule.** `BUZZ_NIP_FI_PROVISION_BINDING` (`{"host_suffix":
..., "authorized_issuers": [...]}`) is parsed in `buzz-auth` with
`BUZZ_NIP_FI_ISSUERS`, whatever `BUZZ_NIP_FI_MODE` is set to, and both
the relay and `buzz-admin` use the same parser. Each authorized issuer
must be a configured issuer (1 to 2048 bytes), and the suffix must not
cover any host declared in `BUZZ_NIP_FI_COMMUNITIES`; an unreadable
declaration refuses startup even in mode `off`.
`ProvisionBindingPolicy::is_bindable(host)` is true for a host exactly
one label under the suffix that is not reserved. It decides
creation-time binding, explicit `bind`, and what the lookup route
reports.

**Binding on creation.** Rows are written in the same transaction as the
community insert on all three creation paths (`POST
/operator/communities` `create_only`, its legacy convergence branch, and
startup bootstrap), and only when the call actually created the
community, so existing rows are never rewritten.

**Reserved host.** A host whose `https://<host>` equals a configured
`command_audiences` value never holds a binding. Operator provisioning
of it is rejected with a 400 and the `reserved_host` error code,
bootstrap creates it unbound, and the availability route reports it
unavailable with an error code. `main.rs` calls
`verify_reserved_hosts_unbound` at startup; if a reserved host has rows
the relay refuses to start and names the fix (`buzz-admin nip-fi unbind
--host <h> --issuer <i>`, or revert the command audience). A database
failure during that check is a separate `Check` error.

**Operator commands.**
- `buzz-admin nip-fi backfill` pages unbound communities by host (1000
per page) and binds each page with one `INSERT ... SELECT` limited to
active communities. It skips communities being deleted, always prints
`{rows_bound, unbound, unbound_hosts, truncated}`, and exits non-zero
while any bindable community is still unbound. Archived communities are
bound on purpose. Both bind paths take the shared deletion lock and then
lock the community row (`FOR NO KEY UPDATE`, in id order for a batch),
the same order deletion uses, and the backfill insert also requires the
community to still have no binding, so an operator `bind` that lands
after the backfill listed a community wins and the default issuer is not
added beside it.
- `buzz-admin nip-fi bind --host --issuer` refuses a reserved host, a
host outside the suffix, or an unconfigured issuer.
- `buzz-admin nip-fi unbind --host --issuer` refuses to remove a
community's last issuer (archive or delete the community instead), with
one exception: when a valid provisioning policy shows that backfill
can't bind the host (it's reserved, or outside the suffix), the last
issuer can be removed. That is the reserved-host recovery path in the
runbook. A missing or malformed policy doesn't block `unbind`; it just
means the exception never applies.

**Lookup route.** `GET /operator/communities/nip-fi-binding?host=`
(NIP-98, `RELAY_OPERATOR_PUBKEYS`) reads the database and returns
`{host, active, issuers[]}`. `host` is the stored host. It returns 404
for an unknown host, 200 with `active:false` for an archived or
quiescing community, and `issuers:[]` when no provisioning policy is
set. It lists only issuers that are configured and on a bindable host.
kgoose depends on this contract; it is also documented in the runbook.

**NIP-FA.** The `relay_url` bullet now also says: "An adapter MAY obtain
its exact relay list from a configured, authenticated source; it MUST
still compare `relay_url` exactly."

**Deployment dependency.** The kgoose config side is already handled by
[cash-server#137671](https://github.com/squareup/cash-server/pull/137671).
In public-community mode it requires the command audience not to be a
community audience.

97e1f6a082 fix(db): validate channel roster snapshots in the app writer (#8316)
## Summary

Phase 1 of retiring the channel roster snapshot trigger
(`trg_events_guard_channel_roster_snapshot`, migration 0032).

Every admitted writer that can store a kind 39002 roster snapshot now
runs the same check the trigger runs, on the same transaction and under
the same lock:

- `LockedMemberSnapshot::replace_member_event` (relay's live roster
publisher) validates the snapshot it already holds the membership lock
for, before soft-deleting the old head.
- `insert_event_on` and `insert_event_with_thread_metadata_tx` (generic
event writes).
- `replace_parameterized_event_in_transaction_impl` (inside its existing
savepoint) and `Db::replace_addressable_event` (admin reconciliation
path), after dominance checks and before the old head is deleted.

The validator (`validate_channel_roster_snapshot`) is a direct port of
`guard_channel_roster_snapshot()`: four-field `p` tags, 64-char hex
pubkey, empty relay field, valid role, and an exact match against active
`channel_members` rows. It raises the same `23514` messages, so callers
still see `DbError::Sqlx(sqlx::Error::Database(..))` with the same code
and text.

**Lock order:** replacement key, then channel-membership key, then the
canonical read, then the old-head `UPDATE` and the write. Legacy writers
took the membership key later, at the trigger's INSERT, after the
old-head row locks. Taking it before the `UPDATE` is not the same order,
but it is strictly safer: it removes the row-lock/membership-key cycle.
The membership writers in `channel_members.rs` take the same membership
key before they change rows. Not every membership writer does yet:
`execute_kick_with_marker` (reached from report enforcement) and
`deploy_kick_member` in `relay_admin_actions.rs` set `removed_at`
without the key, so a kick can commit after a roster passes validation
and before that roster commits, leaving the removed member listed. The
retained trigger has the same gap, so this PR neither causes nor closes
it. When the trigger also runs it re-takes a key this transaction
already holds; transaction advisory locks are re-entrant, so this adds
no wait.

The validator is one verdict query on the happy path. On failure it
raises the trigger's exact error via a `DO` block, so mixed-version
behavior is identical; phase 2 can switch to a typed `DbError`.

**Unchanged on purpose:** the trigger, its function, migration 0032, and
the startup probe `verify_channel_roster_fence_behavior`. Pods still on
the old version depend on them. Phase 2 drops them once this version is
running everywhere.

## Tests

New PG tests in `channel_members.rs` `postgres_tests`, each with only
the roster trigger disabled (the helper asserts the catalog check then
fails):

- `app_roster_guard_matches_trigger_for_roster_input_table`: 19 shape
and membership cases (3/5-field tags, short and non-hex pubkeys, relay
field, unknown role, duplicate, role mismatch, missing/extra member,
uppercase hex, non-`p` tags, empty rosters, all roles). For each one,
the app outcome through `Db::replace_addressable_event` must equal the
trigger's outcome on a raw INSERT, including SQLSTATE and message.
-
`app_roster_guard_locked_writer_rejects_stale_and_accepts_current_without_trigger`
-
`app_roster_guard_covers_generic_and_parameterized_writers_without_trigger`
-
`app_roster_guard_rechecks_after_concurrent_membership_commit_without_trigger`:
the 0032 race. A newer membership commits while an older snapshot waits
on the membership key. The barrier is `pg_locks` with a bound, not
sleeps.

`stale_legacy_roster_cannot_replace_new_locked_snapshot`
(`replaceable.rs`) and `desired_schema_rejects_stale_legacy_roster_role`
(`channel_members.rs`) now simulate the old binary inline (replacement
key, old-head `UPDATE`, raw INSERT) instead of calling the app API, so
they test the retained trigger again. The replaceable.rs one keeps its
one-connection pool, so it still catches self-deadlock.

`observability_source.rs` gains
`every_production_event_insert_runs_the_roster_guard`, which requires a
real guard call in every production `INSERT INTO events` function, with
explicit exceptions (NIP-43 membership and push lease rows, both
`channel_id` NULL, and the two rolled-back startup probes), plus a
self-test.

Falsified: removing one guard call fails the source policy; dropping the
role clause or `lower()` fails the parity table; disabling the trigger
fails both legacy tests. The PG tests are picked up by the `postgres-ci`
nextest filter (`test(/postgres_tests::/)`); the source policy runs in
`just test-unit`.

### Coverage limits (review follow-up)

- `every_production_event_insert_runs_the_roster_guard` is a presence
check. It rejects missing, commented, and quoted calls, but it does not
prove a call is awaited, reachable, or passed the event's real kind and
channel. Behavior is covered by the PG tests above. The test now says
this in its doc comment.
- Exemptions match by function header. A kind 39002 insert added inside
one of the four exempt functions would pass the policy. This is
documented next to the exemption list.
- The 19-case parity table and the race test drive
`Db::replace_addressable_event` only. The generic, parameterized, and
locked writers get the mismatch case only, and the parameterized path's
membership-key-before-delete ordering is not exercised concurrently. All
five writers call the same validator, so this PR doesn't widen these
tests.
- `disable_roster_trigger` commits `DISABLE TRIGGER` on the test
database. That is safe under the per-test database harness the
`postgres-ci` profile uses, but not against a shared database. Its doc
comment now says so.

## Validation

Run on a Blox workstation (private PG 16 and Redis) against a tree
byte-identical to this commit:

- `cargo fmt --all -- --check`, `cargo clippy --workspace --all-targets
-- -D warnings`, `cargo nextest run -p buzz-db --lib`: pass.
- `cargo nextest run -p buzz-db --test observability_source`: 19 passed.
- `scripts/postgres-test-run.sh -p <pkg>` for buzz-admin, buzz-audit,
buzz-deletion, buzz-push-gateway, buzz-relay, buzz-search,
buzz-workflow: pass.
- buzz-db: the full run passed 513 and was stopped at a 240 s deadline
on `writer_pool_rejects_non_read_committed_database_default`, which
hangs the same way on the unmodified base. A second run excluding the
three host-flaky runtime tests already reproduced on the base passed all
511 others.

## Simpler?

Not yet. While the trigger is still in place, the check runs twice.
Phase 2 deletes the trigger, its function, the startup catalog and
behavior probes, the migration.rs equivalence asserts, and the pgschema
reconcile entry, which leaves one check in Rust.

## Phase 2 (separate PR, after fleet rollout)

**Prerequisite before claiming complete roster serialization (phase 2 or
anywhere else):** make both kick paths take the channel membership key
before they change rows, and add a concurrent kick-vs-roster-publication
test. The retained trigger does not prove this; it has the same gap.


A new migration drops the trigger from `events` and its partitions, then
drops `guard_channel_roster_snapshot()`. It also removes the schema
files and includes, `verify_channel_roster_fence*` and the relay startup
call, the migration.rs asserts, and the probe tests, and updates
`scripts/reconcile-schema-after-pgschema.sql`.

60de1db0b8 fix(db): admit fleet sweeps per tenant instead of in-SQL fence predicate (#8318)
## What

Removes every production call to the SQL fence predicate
`community_write_allowed()` from application SQL, so no application
mutation depends on the boolean predicate anymore. This is one
prerequisite for BUZZ-315 part B; #8322 (tolerating absent fence
objects) is a separate one. The triggers and SQL functions stay in this
PR because mixed-version pods still depend on them.

The predicate isn't inlined. It's a VOLATILE plpgsql function that takes
the deletion lock and *then* reads lifecycle state on a fresh snapshot,
and an inline expression would read state from the statement's start
snapshot. A separate earlier check would race deletion. So each sweep
now:

1. reads its candidate community IDs with a plain read, bounded the same
way the original statement was,
2. opens one `AdmittedTx` per community
(`begin_community_sweep_transaction`, a thin wrapper over
`begin_community_write_transaction` that turns an admission refusal into
"skip this tenant"; the four periodic sweeps go through
`sweep_admitted_communities`, which also owns their error handling),
3. runs the original mutation scoped to `community_id = $1` and commits.

| Site | Change |
| --- | --- |
| `runtime/push_enqueue.rs` | Deleted the redundant predicate. This
transaction already calls `guard_transaction`. |
| `store/relay_invite.rs` `reap_expired_relay_invites` | Keeps the
global expiry order and the 1,000-row ceiling. Candidates are
pre-filtered to active tenants so fenced invites can't fill the batch.
Admission is still what authorizes the write. |
| `store/workflow.rs` `prune_scheduled_workflow_fires_before` | Prunes
per admitted community and sums the row counts. |
| `store/channel.rs` `reap_expired_ephemeral_channels` | Archives per
admitted community and returns the committed rows, so the relay still
runs their system and discovery follow-ups. The candidate read has no
lifecycle pre-filter (it has no `LIMIT`, so admission alone decides). |
| `store/event.rs` `backfill_d_tags` | Backfills per admitted community
at startup. |
| `store/push.rs` `claim_due_match_batch_with_loader` | Picks the
earliest due active community, admits it, and claims under the same `FOR
UPDATE OF q SKIP LOCKED` and batch limit. It skips at most 16 tenants
that fence between the read and admission. |
| `store/push.rs` `reap_exhausted_matches` | Reaps per admitted
community. |

**Tenant failures.** The four periodic sweeps (invite reap, workflow
fire prune, channel reap, exhausted match reap) log a warning and
continue when one tenant fails. That tenant's rows are left unmodified
and stay eligible, so the next tick retries them. A tenant error doesn't
abort processing of the other tenants already in the selected candidate
page. Invite cleanup keeps its oldest-first 1,000-row selection, so if
one tenant owns that entire page and its delete keeps failing, tenants
outside the page wait. No persistent tenant-local failure for that
delete is known in the current schema, and base aborted the whole page
on any error. The returned count or rows cover the tenants that
committed. Claim, enqueue and the startup backfill still return the
error to the caller.

**Database outages.** A connection-level error (pool acquire timeout,
closed pool, socket I/O; `DbError::is_connection_unavailable`) isn't
tenant-local, so it stops the periodic sweep at that tenant instead of
moving on. Without this, an outage that began after the candidate read
cost one writer acquire timeout and one warning per remaining tenant,
and invite cleanup runs inside the usage-metrics leader tick. Rows
already committed are still returned, so reaped channels keep their
follow-ups. Remaining tenants retry next tick.

**Known limit (pre-existing, tracked separately):**
- *Claim at a locked head.* `claim_due_match_batch_with_loader` returns
`None` once an admitted tenant claims zero rows. If every due row in the
oldest active tenant is row-locked, younger tenants aren't tried on that
call. Base behaved the same way. This PR doesn't change it.

## Tests

All tests use a one-session fixture (`test_support::admission_fixture`)
with `session_replication_role = replica`, so the trigger backstop is
off and only application admission protects the fenced tenants. The
fixture shadows `community_write_allowed` with a function that raises,
in a per-call `admission_test_<uuid>` schema.

- One test per site: a quiescing tenant's rows are untouched while an
active tenant in the same sweep still progresses.
- Race tests for invite reap, channel reap and claim. These are the
sites where the candidate read already filters out fenced tenants. Each
test holds the tenant's deletion lock, waits until the sweep is blocked
in admission, fences the tenant in that transaction, and asserts its
rows are untouched. The claim test also asserts that a second active
tenant is claimed in the same call.
- `channel_reap_returns_committed_rows_after_earlier_tenant_error` and
`periodic_reaps_continue_after_tenant_error_and_retry_retained_rows`
inject a per-tenant failure. They check that later tenants commit, that
the failed tenant's rows are retained, and that the next call processes
them.
- `fleet_sweep_stops_at_first_unavailable_connection` runs the sweep
helper against a closed pool with three candidates and asserts only the
first is attempted.
`fleet_sweep_returns_committed_results_when_database_drops_mid_page`
(PostgreSQL) commits the first tenant, closes the pool, and asserts the
first tenant's result is returned and the sweep stops at the second of
three candidates.
`connection_unavailable_covers_only_pool_and_io_failures` pins the
classification; the per-tenant failure tests above confirm a
database-raised error still continues.

Falsification, each with the tests failing as expected:

| Mutation | Result |
| --- | --- |
| Original SQL restored at invite sweep, push claim, d-tag backfill |
0/3 pass (`legacy SQL fence predicate called`) |
| `guard_community_write` returns `Ok(())` after taking the lock | race
tests + channel reap test 0/4 pass |
| Per-tenant errors abort the sweep again | 0/2 pass |
| Sweep helper `continue`s instead of stopping on a connection-level
error | `fleet_sweep_stops_at_first_unavailable_connection` and
`fleet_sweep_returns_committed_results_when_database_drops_mid_page`
fail |
| Sweep helper drops already-committed results when it stops (`return
Vec::new()`) |
`fleet_sweep_returns_committed_results_when_database_drops_mid_page`
fails |
| Sweep helper removed from the source-policy chokepoint check |
`serving_table_writes_expose_syntactic_chokepoint_or_guarded_tx_routes`
fails |

The PostgreSQL tests are under `postgres_tests` modules with `#[ignore =
"requires Postgres"]`, which puts them in the `.config/nextest.toml`
PostgreSQL filter. CI evidence is under Verification.

## Verification

CI at head `5d37fbda` ([run
38925996275](https://github.com/block/buzz/actions/runs/38925996275)) is
green. The PostgreSQL job ([job
117062895683](https://github.com/block/buzz/actions/runs/38925996275/job/117062895683))
passed 1017/1017. That includes named PASS lines for all 30
`admission_postgres_tests`,
`fleet_sweep_returns_committed_results_when_database_drops_mid_page`,
and both writer-pool tests listed below. Unit Tests ([job
117058136482](https://github.com/block/buzz/actions/runs/38925996275/job/117058136482))
has PASS lines for
`connection_unavailable_covers_only_pool_and_io_failures` and
`fleet_sweep_stops_at_first_unavailable_connection`.

Local gates ran on a Linux cloud workstation against private PostgreSQL
16 and Redis. The tree was `735170df`, which is this head rebased on
`main` `c0ab789`, so the gates built the merge result.

| Gate | Result |
| --- | --- |
| `cargo fmt --all -- --check` | pass |
| `cargo clippy --workspace --all-targets -- -D warnings` | pass |
| `cargo nextest run -p buzz-db --lib --tests` | 185 passed |
| `scripts/test-postgres-test-discovery.sh` | pass |
| PostgreSQL lane for buzz-db (excluding the two writer-pool tests
below) | 530 passed |
| PostgreSQL lanes for buzz-admin, buzz-audit, buzz-deletion,
buzz-push-gateway, buzz-search, buzz-workflow | all pass |
| PostgreSQL lane for buzz-relay | 413/426. The 13
`group_state_postgres_tests` fail with `PoolTimedOut` on unmodified
`main` `c0ab789` too (see below) |
| The three mutations in the falsification table above (`continue` ×2,
`return Vec::new()`) | each fails its target test |

These failures happen only on the workstation, and each one passes in
CI's PostgreSQL job at this head:
- `writer_pool_metrics_stop_after_session_timeout_setup_failure` stalls.
It's an unchanged writer-pool configuration test, and it stalled the
same way at earlier heads.
- The 13 relay `group_state_postgres_tests` fail at the same point,
`ensure community: Sqlx(PoolTimedOut)`, on unmodified `main` `c0ab789`.
This PR doesn't touch `buzz-relay`.

## What got simpler

- No application mutation calls the boolean predicate
`community_write_allowed()` anymore. Dropping the fence objects still
has other dependencies: serving-write lease acquisition calls
`assert_community_write_allowed()` (`store/deletion.rs:3068`), catalog
validation requires both functions (`store/deletion.rs:1195-1198`), and
the triggers and compatibility SQL still use them. Those belong to #8322
and part B, not this PR.
- The claim's `target` CTE is gone, and every sweep uses the same
admission-and-skip helper.
- The four periodic sweeps share one loop (`sweep_admitted_communities`)
for admission, skip, continue-on-tenant-error and stop-on-outage,
instead of four copies of it.
- The source policy treats that helper as a tenant-local chokepoint, so
`backfill_d_tags` no longer needs a reviewed exception.
- The per-tenant loops add code, because each community now gets its own
admitted transaction.

2745a419a8 buzz-db: tolerate absent universal write-fence objects (expand) (#8322)
## What

This is the expand step for retiring the 32 universal
`community_write_fence_*` triggers and their SQL functions (BUZZ-315).
Relay pods auto-migrate at boot (`BUZZ_AUTO_MIGRATE`). The drop
migration therefore runs while the previous release is still serving,
and that release must not depend on the objects it drops. Today the app
depends on them in four places, and this PR removes all four from its
own code paths. Seven in-SQL `community_write_allowed` predicates in
fleet sweeps and push (`push_enqueue.rs`, `channel.rs`, `event.rs`,
`push.rs`, `relay_invite.rs`, `workflow.rs`) are #8318's scope. The
release is independent of the fence functions only with both this PR and
#8318. **It changes no schema.** The objects stay and keep working until
the follow-up drop PR.

| Old dependency | Now |
|---|---|
| Startup and readiness (`validate_serving_catalog_on`) require
`community_write_allowed`, `assert_community_write_allowed`,
`enforce_community_write_fence` and all 32 triggers | No longer
required. Still required: the tenant tables,
`community_deletion_lock_key` and the enabled community tombstone
trigger. |
| Serving-lease admission runs `SELECT
assert_community_write_allowed($1)` | Uses `guard_community_write`, the
same shared lock and state check as ordinary serving writes, in the same
transaction as the lease `INSERT`. Fenced or missing communities still
map to `AccessDenied`. |
| Live scoped-table discovery calls
`community_write_fence_excluded_table()` | Uses a Rust
`EXCLUDED_SCOPED_TABLES` list. A unit test pins it equal to the SQL list
while both exist. |
| The deletion executor compares the live `fenced_tables` against the
frozen inventory | Only tenant-table equality is compared. Inventories
**still record** live fences, so an older executor that validates an
inventory frozen by this release still matches. The digest still covers
the full frozen manifest. |

`lock_community_deletion_shared` now refuses transactions that are not
READ COMMITTED, so every lock-then-read admission gets the check:
`guard_community_write`, serving-lease finalization
(`guard_transaction_with_serving_lease`), lease renewal/verification,
owner preparation and owner-mutation admission. The old SQL assertion
did this check for the lease path, and the trigger backed up the rest.
The isolation level comes back from the existing
`pg_advisory_xact_lock_shared` statement, so the hot path makes no extra
round trip. The refusal comes before any lifecycle-state read.

## Mixed versions

| Combination | Why it is safe |
|---|---|
| Previous release, this DB | No schema change, so all old checks still
see the 32 fences. |
| This release, DB with fence objects | Extra objects are tolerated, and
the trigger backstop still applies. |
| This release **plus #8318**, DB without fence objects | Serving,
readiness, lease admission and deletion proven by
`migration_schema_fence_objects_are_optional_for_serving_and_deletion`,
which drops them inline. Without #8318, serving and deletion still work,
but the push matcher, exhausted-job reaper, invite retention, ephemeral
reaper and startup d_tag backfill fail with `42883
community_write_allowed(uuid) does not exist` (seen in deploy-stack
E2E). |
| Older executor, inventory frozen by this release | `fenced_tables` is
still populated from the live catalog (32). |

This PR does not depend on #8318 to merge and can ship alongside it, but
it is not drop-safe alone. The drop PR (#8323) needs #8219, #8318 and
this PR deployed on every pod, and every rollback image after the drop
must include #8318.

## Tests

-
`store::deletion::postgres_tests::migration_schema_fence_objects_are_optional_for_serving_and_deletion`
migrates to 0060. It then runs the following with the fence objects
present, then again after dropping them inline:
  - serving startup
  - readiness
  - the deletion catalog check
  - `inventory_schema`
  - lease acquire/release
- `AccessDenied` for quiescing, fenced, tombstoned and missing
communities
-
`store::deletion::postgres_tests::deletion_lock_admission_rejects_pinned_snapshot_isolation`
checks that REPEATABLE READ and SERIALIZABLE are refused by both
`guard_community_write` and `guard_transaction_with_serving_lease`. The
lease case uses a never-acquired lease, so if the isolation check is
skipped it fails as stale instead.
- `buzz-deletion`
`postgres_tests::approved_legacy_fence_inventory_accepts_current_catalog`
checks that a legacy digest with 32 fences validates against a live
catalog with none, and that an unknown tenant table is still rejected.
-
`store::deletion::tests::scoped_table_exclusions_match_sql_during_transition`
checks exclusion-list parity.
-
`store::deletion::postgres_tests::serving_lease_acquire_waits_for_fence_lock_then_refuses`
holds the exclusive deletion lock and checks that lease acquisition
stays pending. It then commits `fenced` and requires `AccessDenied` with
no lease row persisted. Removing the lease path's
`guard_community_write` call fails this test, while the other four
lease/admission tests above still pass.
- `buzz-deletion`
`serving_guard_heartbeats_long_operation_through_quiescing` now requires
`AccessDenied` for a lease acquired during quiescing, rather than any
error.

Each test was confirmed to fail when its fix is removed (rc 100, 0/1):
the isolation refusal, the three validators restored to the base
version, the fence-list comparison restored, and one name dropped from
the Rust list.

## What got simpler

The lease path loses its special SQL assertion and its error-code
translation and reuses the ordinary app guard. The serving and deletion
catalog checks each lose one requirement. No new abstraction. The
`fenced_tables` reader stays only for mixed-version executors; the drop
PR deletes it.

**Identified debt (pre-existing, outside this diff):**
`runtime::postgres_tests::writer_pool_rejects_non_read_committed_database_default`
hangs on clean `177551dda` too.

## Verification (Blox, tree identical to this commit)

| Gate | Result |
|---|---|
| `cargo fmt --all -- --check` | pass |
| `cargo clippy --workspace --all-targets -- -D warnings` | pass |
| `cargo nextest run -p buzz-db --lib` | 167/167 |
| `scripts/test-postgres-test-discovery.sh` | pass |
| `scripts/postgres-test-run.sh -p` buzz-admin / audit / deletion /
push-gateway / relay / search / workflow | all rc 0 (4, 7, 12, 11, 402,
20, 2) |
| `scripts/postgres-test-run.sh -p buzz-db` | 510 pass, 1 fail: the
pre-existing hang above, interrupted |
| Round 2 (this head): `-p buzz-db` / `-p buzz-deletion` | 511 pass +
the same pre-existing hang interrupted / 12/12 |

The new PG tests are selected by the `postgres-ci` filter
`(test(/postgres_tests::/) or binary(/^postgres_/)) and not
test(/(^|::)external_infra[^:]*::/)`.

2d0f78c6e1 feat(auth): support explicit mesh JWKS transport (#8382)
## Summary

Allow an issuer to opt into mesh HTTP for its JSON Web Key Set (JWKS).
Public HTTPS remains the default. This supports deployments whose
service mesh authenticates and protects the key endpoint.

The sealed source contract selects transport and contributes to policy
identity. Mesh mode requires a DNS hostname and checks every resolved
address against an explicit allow-list before pinning one address. Both
modes disable proxies, reject redirects, cap responses, and enforce a
whole-fetch deadline. The relay cannot verify mesh security: operators
must enforce mutual TLS, endpoint authorization, and egress
restrictions.

### Related issue

No duplicate mesh-JWKS issue or PR found. Existing NIP-FI relay
enforcement: #7224. No deployment change is included.

### Testing

- At `eccb8cb19420abda44cf6e5e62b1361e2843bd1d`: full auth package and
auth/relay all-target clippy passed. Full relay package passed: 1,457
library tests, 37 binary tests, and 9 boot tests; 446 tests were
ignored.
- At prior head `113939838cd81d5e8d0b0f8783c42ffaae44a4d3`: the full
relay library suite failed the demo echo test (1,455 passed, 1 failed,
440 ignored). Independent checks reproduced that timeout at base
`d61fe2071d2b3d8e56dd931947f16bfe0d6173fe`; the receive-cancellation
defect is outside this change. A later pass does not establish that
defect is fixed.
- Three falsifying mutations at `eccb8cb194` were caught: mixed DNS
answers, proxy bypass, and whole-fetch deadline. The full locked auth
package passed after restoring the exact source.
- At `eccb8cb194`, `cargo build --locked --release -p buzz-relay -p
buzz-cli -p buzz-admin` passed with command-local
`CARGO_PROFILE_RELEASE_STRIP=none`. This avoids a macOS loader error
without a source, lockfile, or project-profile change.
- Earlier hooks failed the ACP signal test and Tauri login-shell PATH
test. The ACP failure also reproduced on unmodified main `93ffc37c`.
Main merged without conflict. The full Tauri package then passed with
`RUST_TEST_THREADS=1`: 3,422 library tests and 3 integration tests, 19
ignored. All pre-push hooks passed with that same command-local setting;
no hook or test was skipped.
- At `eccb8cb194`, isolated `just test` passed all 107 runner steps. The
monolithic `just ci` run timed out after 1,120 seconds; all recipes
passed across that run and separate `just desktop-tauri-test`, `just
web-build`, and `just mobile-test` invocations. No monolithic pass is
claimed.
- Exact-head release live-local checks passed: loopback HTTP mesh JWKS
warm; valid assertion 101; expired/wrong issuer/wrong audience 403;
valid signed disconnect 200; wrong command audience 403. Redirect-only
JWKS returned assertion 503 without a request to its target. Both
omitted/default and explicit public transport rejected HTTP at startup.
- A separate NIP-FI-off release CLI smoke test created an open channel,
sent an accepted message, read it back, and fetched its thread. The
assertion probe closes after upgrade; it does not prove a complete
NIP-42 session. Local loopback tests do not prove deployment mesh
authentication, endpoint authorization, egress controls, or real `240/4`
routing.

c0ab789499 feat(buzz-db): retire the channel-TTL trigger (#8210)
## Summary

This drops the channel-TTL event trigger. The application already
refreshes ephemeral-channel deadlines in the event transaction
(`event_follow_up::refresh_channel_ttls`, from #8135), so the trigger
only repeats that work.

This PR originally retired both follow-up triggers. #8352 has since
retired the push-match trigger in migration 0063, so after the rebase
this PR covers only the TTL half.

Migration `0065_retire_channel_ttl_trigger.sql`:
- `SET LOCAL lock_timeout = '5s'` (the same bound as 0063)
- drops `events_refresh_channel_ttl` and
`refresh_channel_ttl_after_event_insert()`

Dropping the trigger on the partitioned parent also drops its partition
clones. Published migrations, including 0022 and 0024, stay
checksum-frozen.

The same objects are removed from `schema/` (`schema/functions/…`,
`schema/triggers/events.sql`, `schema/schema.sql`) and from the pgschema
reconcile script. After this, migrated and desired-state databases have
no event follow-up triggers.

Tests:
- `follow_up_retirement_tests.rs` (renamed from
`push_retirement_tests.rs`): the push-retirement upgrade test now stops
at 0063. A new test upgrades 0064 → 0065 and checks that the TTL trigger
is gone from the parent and every partition, that the function is gone,
and that the published checksums haven't changed.
- `event_follow_up_postgres_tests.rs`: the contract now has two arms.
`AppOnly` is the shipped schema, where both triggers are absent. `Dual`
reconstructs the historical overlap of both triggers. The `PushRetired`
arm (the push trigger dropped, the TTL trigger kept) was the shipped
state before this PR. Its tests are removed because `Dual` and `AppOnly`
together cover it.
- `embedded_migrator_contains_consolidated_initial_schema` pins the 0065
statements and checks that both objects are absent from the desired
schema.

**Deploy gate:** do not run 0065 against a database still served by a
relay older than #8135. After 0065, raw SQL writers no longer refresh
TTL deadlines. `docs/push-gateway-deployment.md` is updated to match.

### What got simpler

The trigger and the app no longer both refresh TTL deadlines; the app is
now the only producer. One plpgsql function and one trigger are gone
from both schema paths, and 8 per-partition drops are gone from the
reconcile script. The follow-up contract drops from three arms to two.

### Testing

Head is `4f7d0baf0`. Results below are at `678927730` unless noted.
`678927730..4f7d0baf0` changes only one test in
`crates/buzz-db/src/store/event.rs`, described in the first bullet.

- **Fixed test,
`permanent_channel_event_commits_do_not_lock_the_channel_row`**
(`4f7d0baf0`).
- **Why it changed:** after 0065, its raw-pool inserts no longer ran any
TTL refresh, so the test passed whatever `refresh_channel_ttls` did.
This was raised in review.
- **What it does now:** it inserts through the production `AdmittedTx`
path and keeps the barrier and the tuple-lock probe. It commits all N
transactions while an external transaction holds `FOR SHARE` on the
channel row. It also asserts that no
`buzz_db_channel_ttl_refresh_failures_total` is counted.
- **Mutation check:** with `SELECT … FOR UPDATE` injected into
`refresh_channel_ttl`, the new test fails (`must not wait on the channel
row`, timeout at 10s). The old test passes under the same mutation.
  - **Blox:** fmt and `buzz-db` clippy pass.

- **GitHub CI at `4f7d0baf0`:** every required check passes (56 pass, 0
fail). CI builds the merge ref with `main` `93ffc37cb`.
- **New and renamed tests, checked by name in the CI logs at
`4f7d0baf0`.** These pass in PostgreSQL Domain / PostgreSQL Tests
([117033725006](https://github.com/block/buzz/actions/runs/38915998692/job/117033725006)):
  - `permanent_channel_event_commits_do_not_lock_the_channel_row`
-
`migration_schema_ttl_retirement_drops_every_partition_trigger_and_keeps_checksums`
-
`migration_schema_push_retirement_preserves_ttl_and_published_checksums`
-
`event_insert_ttl_refresh_handles_permanent_ephemeral_duplicate_and_activation_race`
- `{desired,migration_schema}_event_follow_up_contract_{dual,app_only}`
(four tests)

`embedded_migrator_contains_consolidated_initial_schema` passes in Rust
/ Unit Tests
([117024125423](https://github.com/block/buzz/actions/runs/38915998692/job/117024125423)).
No `*_push_retired` test runs anywhere.
- **Blox gates at `678927730`** (private PG16 + Redis, on a workstation
shared with other sessions):
- `cargo fmt --check`, workspace `clippy -D warnings` and `buzz-db
--lib` all pass.
- The `buzz-admin`, `buzz-audit`, `buzz-deletion`, `buzz-push-gateway`,
`buzz-search` and `buzz-workflow` Postgres packages pass.
- `buzz-db`: 517 of 519 tests passed. The 2 that hung, both
`writer_pool_*` tests, were killed. `buzz-relay`: 413 of 426 passed. The
13 failures are covered below.
- **Uncontended reruns at `4f7d0baf0`** on a fresh, idle workstation
(PG16.15, `competing=0` for every arm):
- **`writer_pool_rejects_non_read_committed_database_default` predates
this PR.** It timed out 3/3 at head and 3/3 at `main` `93ffc37cb`, with
a 300s timeout per run.
- **`writer_pool_metrics_stop_after_session_timeout_setup_failure` also
predates this PR.** It timed out 2/3 at head and 2/3 at `main`, and
passed in the remaining run on each side.
- Both tests pass in CI. The gate accepts them as a named exception for
this PR, as a pre-existing hang on the PG16 test environment.
- **`buzz-db`:** 518 of 519 tests passed. The single failure is
`writer_pool_rejects_non_read_committed_database_default`, killed after
it hung (the exception above).
- **`buzz-relay`: still open.** 413 of 426 tests passed. The same 13
`handlers::group_state_postgres_tests` failed as on the shared box, each
panicking at once in its fixture's `ensure community` step with
`Sqlx(PoolTimedOut)`. Contention does not explain them. The fixture's
community setup is in `buzz-db`, which this PR changes. A head/`main`
comparison of the full `buzz-relay` package on the same idle box is
running to find out whether this predates the PR. All 13 pass in CI at
this head.
- **E2E (Gimli, Blox)** at `050e593af`. `050e593af..678927730` changes
only tests and docs; the migration, schema and runtime code are
byte-identical. Gimli's audited verdict: **EXERCISED AND WORKS**, for DB
and relay runtime only. Gimli ran it at `050e593af`; this head's runtime
is byte-identical but was not freshly executed.
- **Upgrade:** a real relay startup took the schema from 0064 to 0065.
That removed the TTL function and the trigger from the parent table and
from all 8 partitions. Checksums for migrations 1–64 are unchanged.
- **Lock-timeout rollback:** with a real lock held, the migration failed
with `55P03` at 5.0007s and the schema rolled back fully to 64. Once the
lock was released, a retry applied 65.
- **Fresh desired schema:** after pgschema plus reconcile, the retired
objects are absent.
- **Real signed kind-9 sends:** on both schema paths, these refreshed
ephemeral-channel deadlines to about +600s. Permanent channels stayed
NULL.
- **Raw SQL insert:** at 64 it refreshed the deadline. After 65 it left
the deadline unchanged, on both the upgraded and the fresh schema.
  - **Not covered:** native or device testing, and deploy.
- **Review:** Legolas found 0 P0 and 0 P1. His three optional P2s are
fixed in `678927730`.
- **No human app test:** this is a DB-only change.
- **Migration numbering:** #8237 and #8372 also add a `0065_*`
migration. Whichever PR merges second must renumber.

d039d9a2d5 fix(relay): confirm requested channels in one membership query (#8378)
## What

A request that names channels with `#h` used to check each channel
missing from the cached access set with its own `is_member` query. These
checks ran one after another, so the database cost of a request grew
with the number of channels it named. That cost is why the relay capped
explicit `#h` values at 128, and why mobile splits large communities
into many requests ([#8342](https://github.com/block/buzz/pull/8342)).

This PR makes the check one query, and then raises the cap.

- **One membership query.** WS REQ, WS COUNT, and HTTP `/query` and
`/count` now share `confirm_requested_channel_access`. It checks every
unconfirmed channel with one `membership_pairs` statement (`channel_id =
ANY($2)`), so one request costs one query, whatever number of channels
it names. `membership_pairs` uses the same SQL rules as `is_member`:
deleted channels and removed members don't count, and it runs on the
writer pool.
- **Hash-set lookups.** Comparing the requested channels with the
accessible set no longer costs requested × accessible comparisons. This
covers `apply_channel_scope_to_query`, the system-channel scope helpers,
the COUNT and bridge loops, and `#h` dedupe.
- **`MAX_EXPLICIT_CHANNEL_VALUES` goes from 128 to 2048.** Huddle
liveness used the same constant to limit session IDs. It now has its own
constant, `MAX_HUDDLE_LIVENESS_SESSIONS`, which stays at 128, because
each linked session still costs a separate mesh-directory lookup.

Authorization rules are unchanged:
- A scoped token still sets the upper limit. A channel outside the token
is never checked.
- Channels already cached and readable system channels are skipped.
- Repaired channels are added in request order, each once, so
`keep_repaired_system_channels_named` still sees the same repaired tail.
- A database error still closes the request (or returns 500 over HTTP).
One difference: the old loop could leave a partial repair if a later
query failed, and that can no longer happen.

## Not in this PR

- **Client chunk sizes.**
`desktop/src/shared/api/relayClientShared.ts:39` and
`mobile/lib/shared/relay/nostr_filters.dart:8` stay at 128. They can go
up only after every relay they talk to runs this change.
- **Per-connection limit on live channel scope.** Each authorized
channel in a live WS subscription still gets a fan-out index entry for
each kind, plus a Redis topic retain. Real membership limits this, not
the cap. Still, an account in at least 2048 channels could now register
up to 1024 × 2048 channel scopes on one connection; before, the most was
1024 × 128. If we want to keep the old worst case, the fix is a limit on
the total channel scope per connection, not per REQ.

## Testing

- `cargo clippy -p buzz-relay --tests` and `cargo fmt` are clean.
- `cargo test -p buzz-relay --lib`: 1449 passed, 6 failed. All 6 are in
`api::media::tests` and fail because the local Postgres on :5432 has no
`buzz` role. Nothing in this change touches them.
- I ran the Postgres lane (`scripts/postgres-test-run.sh`) for the
bridge, req, count, group-state, and system-channel tests on local PG14:
55 passed. That includes the new
`named_channels_missing_from_the_cache_are_confirmed_together`, which
checks that the reader's channels missing from the cache are added in
request order, each once, and that a stranger's channel stays out.
- Not done yet: a live run against a local relay sending a REQ with more
than 128 `#h` values.

7852b1670c fix(search): normalize profile name tiers in one place (#8334)
🤖

## Summary

Profile name search (`POST /profiles/search`, added in #8301) sorts
results into tiers: an exact name first, then a name that starts with
the query, then a name with a later word that starts with it. This PR
stacks on #8301 and fixes two review items.

**Tier normalization in one place.** Before this change, the query was
lower-cased in Rust (`to_lowercase`), and the names were lower-cased in
SQL (`lower()`). These can disagree. Under a `C` collation, PostgreSQL's
`lower()` changes only ASCII letters, while Rust also lower-cases
letters like `É`. So a search for `Émile` did not put the profile named
`Émile` in the exact tier. Now the query and both name fields go through
the same SQL expression: lower-case, collapse whitespace runs to one
space, then trim. The query is bound once and both sides compare equal
by construction. The trim also moved after the collapse, so surrounding
whitespace that the regex turns into a space is now trimmed too.

**Ranking wording.** The doc comment and `docs/profile-search.md` said
"ties keep the NIP-50 order". That was wrong. Ties are ordered by
`ts_rank_cd` over the two name fields only (not the whole profile, as in
NIP-50), then newest first, then event id.

Out of scope, not changed here: matching names that contain escaped
Unicode or newlines, and any new name index.

## Related issue

Review on #8301:
https://github.com/block/buzz/pull/8301#pullrequestreview-5524491230

## Testing

- New case in `profile_names_match_name_words_only`: profiles `Émile`
and a newer `Émilee`, query `Émile`. The exact match must come first.
- Ran the Postgres integration tests against a `postgres:17-alpine`
database created with `--locale=C`:
- this branch: `profile_names_match_name_words_only` and
`profile_names_survive_unparsable_content` pass;
- #8301 code with the new case: `profile_names_match_name_words_only`
fails (`Émilee` sorts before `Émile`).
- Nine other tests in that file fail locally on both this branch and
#8301 because they reuse one database (duplicate community hosts). CI
gives each test its own database.
- `cargo fmt --check`, `cargo clippy -p buzz-search --all-targets -D
warnings`, and `cargo test -p buzz-search`: clean.
- The pre-push hook's `rust-tests` and `desktop-tauri-checks` passed.

f148c0f22c feat(relay): add profile search over name and display_name only (#8301)
🤖
> **Review as a pair with block/buzz-app#1084** (the app change that
uses this endpoint). Either can merge first: the app falls back to the
old search on relays without this endpoint.

## Summary
Searching for a person by name over the relay's general search returns
profiles that only *mention* the text somewhere else: in an avatar image
embedded as text, in the bio, or in the verification address. A search
for "wes" could fill every result page with profiles whose avatar data
happens to contain "Wes", and never return the person actually named
Wes.

This adds a relay endpoint, `POST /profiles/search`, that looks only at
a profile's **name** and **display name**. Every other profile field is
ignored.

**Matching and paging are the same as the relay's existing full-text
profile search** (NIP-50 search over kind:0 profiles with `search_mode:
"prefix"`). A client can switch to this endpoint without a visible
change in which people a query finds:
- Each query word must match a whole word of the name; the last word can
be a prefix. Words can be in any order, so "johnson wes" finds "Wes
Johnson". Case is ignored.
- Pages work the same way: up to 100 results per page, up to page 1000.
- The results are exactly the old results minus profiles that match only
outside their names.

The order is better for people search: exact name first, then names that
start with the query, then names with a later word that starts with it,
then other matches. Ties are ordered by `ts_rank_cd` over the two name
fields only (not the whole profile, as in NIP-50), then newest first,
then event id.

The response is a JSON array of the original signed profile events
(Nostr kind:0), so clients can verify them as they do today. The
buzz-app client change is block/buzz-app#1084.

## Details
- Request: `{"query": "wes", "limit": 20, "page": 1}`. `query` is 1–100
characters after trimming; `limit` is 1–100 (default 20); `page` is
1–1000 (default 1); unknown fields are rejected with 400.
- The search reuses the full-text search's own query builder
(`buzz-search`), so the word rule cannot drift from it. The existing
full-text index on events stays the access path; the name check runs
only on rows the index already matched. There is no new index. One small
migration (`0061`) adds the function `profile_name_fields()`; it reads
no table data, so it runs instantly.
- Only current profiles count: a replaced profile stops matching.
Profiles that are not a JSON object, or whose name fields are not
strings, never match. Content that PostgreSQL cannot read as `jsonb`
(for example a `\^@` escape or very deep nesting) also never matches,
and it cannot make the search fail for everyone else.
- The handler loads the matched events through the normal routed event
read and applies the same reader visibility check as other reads, in
search order.
- Access uses the same checks as the relay's GIF search endpoint: a
signed HTTP request (NIP-98), identity admission (NIP-FI), rate limit,
replay protection, and relay membership. That code moved out of
`gifs.rs` into one shared helper in `bridge.rs`; GIF behavior is
unchanged.
- The route is added to the existing protected-route and NIP-FI
shadow/enforce route tables. Docs: `docs/profile-search.md`.
- Two test-only lines get `sadscan:disable` comments, as other fixtures
already do: an existing public ES256 test key in `router.rs`, and the
local Postgres test URL in the search integration test.

### Related issue
None found.

### Testing
- Postgres test for the search query
(`profile_names_match_name_words_only`): only name fields match (avatar
data URL, `about`, `nip05`, `banner`, non-string names and non-object
content are excluded); words in any order and across both name fields;
whole words only for completed words; ranking order; pages split without
overlap or gaps; replaced profile; other community; `%` literal.
- Postgres end-to-end test through the router: an admitted member gets
only the name-matching signed event, and the returned event still
verifies.
- Request validation unit tests; existing GIF admission tests and router
route-table tests pass.
- Local end-to-end run with buzz-app#1084 against a relay built from
this head, with about 195 seeded profiles. For every query tried, the
endpoint's results were a subset of the full-text search's results; the
only profiles missing were avatar-only matches.

cdfc38ecbd feat(search): add newest-first sort to bridge search (#8371)
## Summary

Adds an opt-in newest-first order to bridge search, so clients can offer
"Most recent" alongside relevance.

- `buzz-search`: `SearchQuery` gains `sort: SearchSort`. `Relevance`
keeps the existing `ts_rank_cd` ordering. `Newest` orders hits by
`created_at DESC, id`, and `page` steps through that order. Newest skips
the exact-profile-lexeme prioritization, which only applies to relevance
ranking.
- Bridge `POST /query`: search filters accept `search_sort: "newest"`.
When the field is missing or has another value, results stay in
relevance order. Community scope, channel intersection and per-hit
authorization are unchanged.
- NIP-11 lists `buzz-search-sort` in `supported_extensions`. Clients
only send the field to relays that advertise it, so they never get
relevance results labelled as newest.
- WebSocket NIP-50 search stays relevance-only. `NOSTR.md` documents the
bridge extension.

### Related issue

N/A

### Testing

- New Postgres integration test
`newest_sort_pages_by_time_then_id_within_scope`. It pages a channel in
newest order, including an equal-timestamp tie split across a page
boundary and a newer hit outside the channel scope. It checks that the
pages join up in `(created_at desc, id asc)` order and that relevance
still ranks the strongest match first.
- Unit tests:
  - `bridge_search_sort_extension_selects_newest_only_when_named`
  - `advertises_nip_cl_and_search_sort_extensions`
- Ran the buzz-search Postgres integration suite, the relay `nip11` and
`bridge_search` unit tests, `cargo fmt --check`, and `cargo clippy -p
buzz-search -p buzz-relay --all-targets -D warnings` on Linux.
- Local relay exercised through signed `POST /query`:
  - NIP-11 lists `buzz-search-sort`.
  - Relevance and newest return different orders.
- Newest pages 1–3 return 25 hits with no gaps or duplicates, including
same-second ties across page boundaries.
- A non-member gets no hits from a private channel; a member gets all of
them.
- Client integration is in a companion block/buzz-app change. It was
exercised end to end against this relay through the production broker:
switching sort, paging, scope changes and capability fallback.

Deployment note: clients only offer newest sorting after a relay with
this change advertises `buzz-search-sort`.

6766174673 chore(push): retire push notification database trigger (#8352)
Buzz must schedule mobile push notifications when it saves an eligible
message. The relay, the server that receives and stores messages, now
does this in application code. An older database trigger still exists.
This trigger is a rule that runs automatically when a message is saved.

This PR removes the old trigger and its supporting database function.
The relay remains responsible for scheduling notifications. Migration
0063 makes this change in existing databases; updated setup scripts
apply it to new databases.

The change does not turn on push notifications. Production migration and
deployment need separate approval. Before deployment, verify the release
images and all pending database migrations. If push needs to be stopped
after release, disable it with the feature flag and keep the qualified
application version and database schema. Do not downgrade the
application image.

### Validation

- Local checks passed: 519 isolated database integration tests, 166
database unit tests, 17 source-policy tests, and the relay push-runtime
tests.
- Tests verify that the migration removes the old trigger, preserves
earlier migration records, and lets the application schedule push work
correctly. A concurrency test exercises the real application path;
deliberately removing its lock makes the test fail.
- [Current-head CI passed on
retry](https://github.com/block/buzz/actions/runs/38752849383/attempts/2).
The first attempt had one database-connection timeout during test setup;
the failed jobs passed when rerun on the unchanged commit.
- Initial local CI and push checks hit unrelated ACP test failures,
which passed when run separately. Only the Rust-test push hook was
skipped under the repository's local-check exception; other applicable
hooks passed.

### Before merge

- [x] Migration 0063 is available and the push trigger remains on [main
at
5397ea4](5397ea49e2).
Recheck if main advances before merge.

5397ea49e2 fix(push): verify extended App Attest proofs with a focused owned module (#8329)
## Summary

Apple SDK 27.1 device captures include authenticator extension data that
the current verifier rejects. Replace the general appattest dependency
with a private gateway module that verifies the complete original bytes,
frames enrollment and assertions separately, and accepts well-formed
optional extensions without SDK-specific length or flag allowlists.

The module retains established signature, P-256, CBOR, and
certificate-chain libraries. App identity, exact enrollment environment,
credential/key binding, nonce, challenge, and increasing-counter checks
remain enforced. Bounded parsing rejects ambiguous duplicate keys,
truncation, trailing data, and oversized inputs. Fixture helpers are
test-only. Adapted code retains both upstream MIT notices and source
provenance.

Category/version properties remain authenticated observations under the
chosen compatibility-release policy. This does not implement Apple's
additional distribution-category/version enforcement; introducing those
restrictions requires a separately defined deployment policy. The
[verification
contract](https://github.com/block/buzz/blob/app-attest-owned-verifier/docs/app-attest-compatibility.md)
records this and other limits.

Related: https://github.com/block/buzz/pull/8020 addresses assertion
extension handling. This change also covers enrollment extensions,
credential-key parsing, and certificate validation.

### Validation

- Gateway suites: 77 default tests and 79 personal-development tests
passed, plus startup policy and Clippy.
- Added signed enrollment/certificate, generated CBOR mutation,
maximum-counter, and PostgreSQL race/replay coverage. All 12 isolated
Postgres tests passed. Apple's historical fixture is tested
structurally, not accepted as a current enrollment. Positive synthetic
leaf certificates are generated at test time.
- Protected SDK 26.5/27.1 enrollments and assertions pass the verifier,
including the same key across SDK upgrades; development enrollment
rejects under production policy. Captures are personal-development
identities, not supported production-identity evidence.
- Full local CI passed Rust tests and reached 6,828 passing desktop JS
tests before an unchanged 10 ms focus-timer test failed; its five-test
file passed in isolation. The pre-push native suite had 3,421 passes and
an unchanged 300 ms child-PID test failure, also passing in isolation.
Prior ACP timing flakes and these unrelated hook exceptions do not waive
required CI.
- Windows CI exposed a missing system OpenSSL installation for the test
fixture generator. The test dependency now builds bundled OpenSSL; all
30 focused App Attest tests pass locally. [Current-head
CI](https://github.com/block/buzz/actions/runs/38636062347) passed,
including Windows Rust, PostgreSQL, and desktop integration tests.
- [Prior-head Codex
review](https://github.com/block/buzz/pull/8329#issuecomment-6177515598)
found no major issues. Carl subsequently identified a dropped
credential-length workaround; fixed in
[27f9f26](27f9f2624f),
with 34 focused/protected tests and Clippy passing. [Current-head Codex
review](https://github.com/block/buzz/pull/8329#issuecomment-6178361143)
found no major issues; physical iOS 26 testing was explicitly waived by
Tom on October 14, 2026. No iOS 26 device test was performed. The SDK
comparison used the same iOS 27.0.1 device, so it demonstrates
SDK-linked variation without establishing OS-version causation.
- Isolated candidate HTTP/device validation passed with separate
authority state and no APNs delivery: SDK 26.5 enrollment/delegation,
SDK 27.1 delegation with the exact same key and installation, and fresh
SDK 27.1 enrollment/delegation. Assertions changed from 37 to 102 bytes
across the upgrade; accepted counter increased from 1 to 3 and
delegation generation from 1 to 2. All three runs rejected tampering and
replay (401) and consumed challenges (404). Existing Buzz app builds
were preserved. No production rollout is included.

- Existing-installation validation passed against the current-head Dev
gateway: a guarded SDK 27.1 diagnostic reused the stored key and
installation, advanced the assertion counter from 88 to 89 and
delegation from 89 to 90, and published the existing active relay lease
at generation 9 (previously 8). Independent database reads confirmed the
changes and preserved key, epoch, and expiry. The original app build was
restored in place with current data and keys intact.

d28f6b2f70 feat(relay): let channel-state filters opt in to system channels (#8182)
🤖
## Summary
After part 2, a client can read a system channel only if it already
knows the ID. This PR lets a client find system channels on purpose,
with an ordinary Nostr filter and no new filter key.

A filter on the channel-state kinds (39000–39003) now also returns the
system channels the reader can read when it has either:

- `#t:["system"]`, the channel type tag that every channel-state event
already carries; or
- any `#P`, the creator tag from #8174. Asking for the channels of a
named creator returns a small result, so it does not fill generic
channel lists.

The filter then matches as usual. Existing clients send neither on these
kinds, so they still never see a system channel.

| Reader wants | Filter |
|---|---|
| My system channels | `{kinds:[39002], #p:[me], #t:["system"]}`, then
their kind:39000 by `#d` |
| Open system channels | `{kinds:[39000], #t:["system"]}` |
| One creator's labeled channel, system or not | `{kinds:[39000],
#P:[creator], #t:[label]}` |

Private system channels stay hidden from non-members, as for any private
channel. Values in one tag filter combine with OR, so `#t:["system",
label]` means `system` **or** the label; use `#P` plus the label
instead.

Part 3 of 3, stacked on part 2.

### Related issue
None found.

### Details
- The opt-in is decided per filter in `handlers/system_channels.rs` and
applies on REQ, COUNT and the HTTP bridge. It applies only when every
kind in the filter is 39000–39003.
- A label alone is not an opt-in.
- `NOSTR.md` documents the system channel query rules.
- **Spec.** NIP-CL says how a filter asks for system channels.
- The relay information document (NIP-11) now lists `"nip-cl"` in
`supported_extensions`. Clients use this to tell if a relay supports
labels and system channels, and refuse those calls on a relay that does
not. NIP-CL documents this.

### Testing
- End-to-end relay test: `#t:["system"]` finds both system channels for
a member and only the open one for a non-member; 39002 `#p:[me]` with
`#t:["system"]` lists the member's system channels; `#P` includes a
creator's system channels; creator plus label returns exactly one
channel with `limit: 1` and excludes another creator's channel with the
same label; a label alone does not return the system channel; COUNT and
HTTP `/query` and `/count` agree.
- The test fails when the opt-in is disabled.
- Unit tests for which filters opt in.

### Stack
These are two stacks. Merge them in this order. Client support
(creating, labeling and finding these channels) will be in
block/buzz-app, not the buzz SDK and CLI.

cdf03f618a feat(relay): leave system channels out of reads that do not name them (#8181)
🤖
## Summary
After part 1, a system channel is still returned by every query that
returns ordinary channels, so existing clients would show it as a chat.
This PR makes the relay leave system channels out of every read that
does not name them. Clients do not need to filter, so clients that know
nothing about system channels stay correct.

| Query | Before | After |
|---|---|---|
| A query that does not name a channel (no `#h`), COUNT, full-text
search, the HTTP `/query` and `/count` routes, artifact queries
(`{"artifact": ...}`), the sidebar | Includes system channels | Leaves
them out |
| "Channels I belong to" (kind:39002 `#p:[me]`) | Includes them | Leaves
them out |
| A filter that names the channel with `#h`, or with `#d` on kinds
39000–39003 | Ordinary read rules | Unchanged: members can read it, and
anyone can read it if it is open |

Push notifications and "you were added to a channel" notifications
(kinds 44100/44101) skip system channels, because a client that received
one would show the channel.

A client that is given a system channel's ID, for example in a pasted
link, can still open it. Naming the ID is the opt-in. This keeps system
channels ordinary NIP-29 groups.

Part 2 of 3, stacked on part 1.

### Related issue
None found.

### Details
- The rule lives in one place: `get_accessible_channel_ids`, the set of
channels a query may read when it does not name one. It is the union of
the reader's memberships and every open channel; both halves now exclude
`channel_type = 'system'`. Because the filter is in SQL before `LIMIT`,
pages stay full.
- A filter that names a system channel adds it to that filter's scope
only (`handlers/system_channels.rs`). A sibling filter in the same
request keeps the implicit set, so naming one system channel cannot
widen another filter.
- Thread windows and the workflows API name their channel, so they
follow the same named-channel rule.
- Artifact queries have their own read check in SQL. It reads a system
channel only when the query's `#h` names it.
- When a request re-checks membership for a named channel that its first
lookup missed, a confirmed system channel joins only the filters that
name it. Before, a reader who joined a system channel during the request
could have it added to a sibling filter's scope.
- The system-channel lookup runs only when a filter names a channel
outside the implicit set, so ordinary queries do not pay for it.
- **Spec.** NIP-CL lists the reads that leave system channels out, and
says when a filter names one. `AGENTS.md` notes this for `get_channels`.

### Testing
- End-to-end relay test (Postgres and Redis) with a private system
channel, an open system channel and an ordinary channel, as a member and
as a non-member: REQ without `#h`, NIP-50 search, COUNT, HTTP `/query`,
HTTP search, HTTP `/count`, the channel list, and 39002 `#p:[me]` return
only the ordinary channel. Named reads by `#h` and `#d` follow
member-or-open on REQ, COUNT, search and HTTP.
- Relay test: adding a member to a system channel sends no kind:44100;
an ordinary channel still does.
- Both tests fail when the SQL exclusion or the named-channel scope is
removed.
- Database test: an artifact in an open system channel is missing from
`{"artifact":"current"}` and present with `#h:[<system channel>]`, for a
member and a non-member. It fails without the channel-type condition.
- Relay test: the membership re-check confirms a system channel that the
system-channel lookup missed. The channel goes to the filter that names
it, and a sibling filter's scope does not include it. It fails without
the fix.
- Unit tests for the per-filter scope. They now run in `just test-unit`
and `scripts/run-tests.sh`.

7b11c6147d test: fix recurring CI flakes in desktop and Postgres lanes (#8343)
Fixes the CI flakes that failed most often across `main` and unrelated
branches from Oct 5 to Oct 14. The counts come from 150 failed `CI`
runs. Every change except the nextest config is test-only.

| Flake | Runs hit | Root cause | Fix |
|---|---|---|---|
| `probe_codex_acp_version_…descendant_holds_pipe_open` | 5 | The test
writes its script in-process and then execs it. If a sibling test spawns
a process in that window, the child inherits the open write fd and Linux
rejects the exec with `ETXTBSY`. The probe swallows that error as
`None`. | Write probe scripts from a short-lived `/bin/sh`
(`write_executable_script`) |
| `empty-edit-delete.spec.ts` (`:51`, `:74`, `:95`) | 11 | The seeded
`mock-general-welcome` id isn't hex, so `formatTimelineMessages` can't
overlay its edit. The post-subscribe window refetch then reverts the
row. | Emit a per-test message with a real id after the exact channel
subscription is live |
| `huddle-transcription.spec.ts:798` | 9 | The composer's delayed
initial autofocus (TipTap `focus()` runs in rAF) lands after the voice
popover opens and dismisses it. | Wait for `message-input` focus before
opening the popover |
| `voice-note.spec.ts:906` | 6 | The fixture `ping.mp3` is about 1s
long, so playback can end before `paused === false` is observed. | Loop
the fixture audio |
| `workflows.spec.ts:291` | 5 | The `Message text` fill runs before the
inspector swaps to the new step, so it fills the trigger's condition
instead. | Scope the fill to the step inspector after its `Action` menu
appears |
| `cluster_global_probe_commits_tokens_and_sessions_prove_coverage` | 3
| The `max-threads = 1` group only serializes these tests with each
other. Other tests' sessions still mask cluster-wide `pg_stat_activity`
(`MaskedActivity`). | `threads-required = "num-test-threads"` |
| `test_usage_metrics_lock_has_single_owner_and_releases_on_drop` | 1
(this PR) | The test retries the lock right after dropping the leader.
Postgres releases a session advisory lock only after the backend notices
the disconnect, so the retry can run first. | Poll for the successor,
bounded at 5s |

### Validation
- **ETXTBSY:** a Linux experiment with Rust 1.95 using the same
write→chmod→spawn pattern under concurrent spawns hit `ETXTBSY` 4–7% of
the time. Using the `sh` writer, it hit 0 of 6,000. I did not catch it
inside the full suite locally, so this fix is based on the mechanism,
not an in-suite repro. All 11 probe tests pass on Linux and macOS.
- **empty-edit-delete:** the baseline failed 16 of 45 runs
(`--repeat-each`, 6 workers, no retries). The spec fix alone brings that
to 4/45. The remaining failures come from a separate product race,
described below.
- **huddle:** the baseline failed 5 of 10 runs. With the fix, 60 of 60
passed without retries.
- **nextest:** checked with a throwaway crate on 0.9.136. A grouped test
with `num-test-threads` ran alone, even with `max-threads = 1`.
- I have not stress-run the voice-note and workflows fixes; they rely on
CI.

### Not in this PR
- **Product bug in `useChannelLinks`:** the debounced `#channel`
autocomplete close lets Enter accept a stale suggestion for about 120ms.
That accounts for the remaining `empty-edit-delete` failures, and it
affects users too. With the spec fix plus a synchronous close, the spec
passed 120 of 120 runs. This needs a product decision, so it's held for
a separate PR.
- **Composer autofocus race:** the delayed autofocus can close an
overlay the user just opened. The real fix is to revalidate when the
delayed focus runs. Overlaps #6530.
- **`thread-head-stale-edit.spec.ts:55`:** a forced click on a
pointer-events-none action bar is suspected, but I couldn't reproduce
it.
- **Remaining ETXTBSY exposure:** about 40 other Rust tests write and
then exec scripts, and 17 specs still edit the non-hex seed message.

8b60dcf8e3 feat(relay): deliver full signed events to operator listeners (#8309)
## Summary

Operator-listener mention notifications now carry the full signed event,
so a listener such as kgoose can wake an agent without first fetching
the event (one signed round trip less on time-to-first-reply).

Because the notification now carries message content, two mitigations
come with it, as agreed in #buzz-security:

1. **Each target signs its own registration.** `POST
/operator/listener/pubkeys` takes `{"registrations": [proof, …]}`. Each
proof is a kind `24245` event signed by the target pubkey, with exactly
one `p` tag (the listener pubkey) and one `u` tag
(`{RELAY_OPERATOR_API_ORIGIN}/operator/listener/pubkeys`), and a
`created_at` within ±60s. The old unsigned `{"pubkeys": […]}` POST body
is rejected with 400. `DELETE` is unchanged.
2. **Only notify a target that can read the event.** Before each
delivery the relay re-checks, on the writer, that:
   - the registration still exists;
   - the event isn't deleted;
   - neither the target nor its recorded NIP-OA owner is banned;
- the target passes the relay-membership gate (with the owner path when
`allow_nip_oa_auth` is on);
   - the channel is open, or the target is an active member.

A delivery that fails the check retries with backoff instead of being
dropped, because a mention can commit just before the target is added to
the channel. It fails permanently, with no HTTP request, once attempts
are exhausted.

The payload is now `v: 2`: the v1 fields plus `event`, the full signed
NIP-01 event.

There's no migration. Existing registrations stay in place and age out
under the 30-day retention; only a configured listener could have
created them. Listeners must sign proofs to register new targets, so
receivers have to accept `v: 2`.

Companion kgoose change: squareup/cash-server#136794 signs registrations
with the agent key. The kgoose receiver in squareup/cash-server#136004
currently accepts only `v: 1` and bodies up to 4 KB, so it needs to
accept v2 and a larger body.

## Testing

- Unit tests:
- proof verification (forged signer, wrong kind, stale or future, other
or ambiguous listener, other or missing endpoint);
  - signed-only request bodies;
  - delivery payload carries a verifiable event;
- unreadable or failed loads retry, then fail, without an HTTP request.
- Postgres tests:
- every access predicate (open, member and non-member private,
channel-less, closed community with target or owner membership, owner
ban, removed member, deleted channel or event, removed registration);
- the route test (signed registration accepted; a proof for another
listener and the unsigned body both rejected).
- Mutation runs confirmed that the membership, owner, ban and
reader-visibility guards each fail a test when removed.
- Local relay exercise with a fake listener:
- signed registration returned 200; unsigned, stale and wrong-listener
proofs returned 400;
- open-channel mentions delivered v2 with an event whose id and
signature verify independently;
- a private-channel mention of a non-member retried without delivering,
then delivered once the target was added.

e645918c63 fix(relay): match pushed-down tags by position, not containment (#8335)
🤖 The relay pushes several tag filters into SQL as JSONB containment
(`tags @> [[name, value]]`). Containment ignores element position, so a
tag like `["x","e",<id>]` or `["meta","t",v]` satisfies `#e:[<id>]` or
`#t:[v]`, and `#t:["t"]` matches `["t","other"]`. Because the predicate
runs before `LIMIT`, a newer event that only matches by containment can
take a `limit: 1` slot; the exact NIP-01 post-filter then drops it and
the real match is never returned. Where no post-filter follows, the
decoy is returned or counted outright.

`push_exact_tag_match` in `buzz-db/src/store/event.rs` keeps containment
as the GIN-indexed prefilter (one array-bound `tags @> ANY(...)`, so the
e-tag planner shape is unchanged) and adds a positional `EXISTS (...
tag->>0 = name AND tag->>1 = ANY(values))`. It now backs every
`EventQuery` tag pushdown:

| Pushdown | Before | Effect of over-match |
|---|---|---|
| `#e` (`e_tags`, query and COUNT) | containment | REQ `limit` slot
theft; COUNT has no post-filter and counted decoys; thread aux closure
returned decoy reactions/replies |
| artifact `#d` (`d_tag_values`) | containment | `limit` slot theft on
NIP-AR identity lookups |
| `custom_tag` (bridge `#buzz-channel`) | containment | no post-filter:
a decoy project/repository was returned for its channel |
| shared-gated visibility (`shared_gated_reader`) | containment of
`["shared","true"]` | a private event tagged `["x","shared","true"]`
took a page slot before `event_visible_to_reader` dropped it, so the
page came back short. Never a visibility leak: the post-filter stays in
place |

**Bridge `/count` honors `#buzz-channel`.** `POST /query` scoped
project/repository reads by `#buzz-channel`, but `POST /count` ignored
it, so a count for one channel counted matching projects in every
channel the reader can see. `/count` now sets the same `custom_tag` on
both its channel-scoped and access-scoped paths, and the COUNT SQL
builder pushes `custom_tag` down exactly like the query builder, so
`/count` and `/query` select the same events on both the fast count and
the post-filtered fallback.

Left unchanged: the retention-free purge predicate for mesh status
(`tags @> [["k","buzz-mesh-status"]]`). It mirrors the migration 0019
trigger, has no `LIMIT`, and only affects how the author's own deleted
event is purged. REQ `#t` outside group-state kinds is still
post-filtered only.

71d7aa0436 feat(relay): add the system channel type (#8180)
🤖
## Summary
Buzz uses channel membership to decide who can read what, and every
channel a person belongs to shows up in their client as a chat. So there
is no way to make a group that exists only for access control, for
example "only this agent and its owner can read the agent's config".
Such a channel would appear in both people's sidebars, search results
and unread counts.

This stack adds a **system channel**: an ordinary channel that queries
leave out unless they ask for it. This first PR adds the type itself.

- `kind:9007` (create channel) with `["channel_type", "system"]` creates
a system channel.
- It is private unless the creator sends `["visibility", "open"]`.
- While it is private, its channel metadata event (kind:39000) carries
the NIP-29 `hidden` marker, which means "hide this group's metadata from
non-members". Until now the relay set `hidden` only for DMs.

On its own this PR does not yet hide system channels from queries. Part
2 does that.

Part 1 of 3, stacked on #8176 (the channel labels and creator lookup
stack, which this feature uses).

### Related issue
None found.

### Details
- Migration 0062 adds `system` to the `channel_type` Postgres enum. No
new columns.
- `buzz_core::channel::ChannelType::System`, and `system` is now a
reserved label name (labels cannot equal a channel type name).
- `buzz-admin` reconcile writes `hidden` with the same rule as the
relay. Usage metrics count system channels.
- **Rollback.** A relay older than this change cannot read `channel_type
= 'system'`. Do not roll back past it while system channels exist.
- **Spec.** NIP-CL gets a "System channels" section. `ARCHITECTURE.md`
lists the `System` type.

### Testing
- Relay test: a system channel is private and `hidden` by default;
opening it removes `hidden`; its first `t` tag is `system`.
- Migration embed and usage-metrics tests.

### Stack
These are two stacks. Merge them in this order. Client support
(creating, labeling and finding these channels) will be in
block/buzz-app, not the buzz SDK and CLI.

a3909acc67 feat(relay): match label and creator filters before the page limit (#8176)
🤖
## Summary
After parts 1 and 2, a client can ask for "channels with label X" or
"channels created by key K". But the relay applied these tag filters
after it read one page of the newest channel events. So a request such
as `{kinds:[39000], #t:["workspace"], limit:10}` could return fewer than
10 channels, or none, while matching channels existed. This PR moves the
label and creator match into the database query, before the page limit.

Part 3 of 3, stacked on part 2.

### Related issue
None found.

### Details
- Applies only when every kind in the filter is a relay-signed
channel-state kind (39000–39003). Other kinds keep today's behavior.
- The database match uses JSONB containment on `tags`, which is
GIN-indexed. Containment can match a little too much (for example, a tag
that contains both strings in another position), never too little. So
the relay still checks each returned event with the normal Nostr filter
rules, and `COUNT` requests keep that check too.
- The same match is applied to the query path and the count path.
- **Spec.** NIP-CL now says that `#t` and `#P` match before `limit`.
- **Choosing one channel.** The relay does not make labels unique, so
two creates for one label can both succeed, for example when two
processes of one agent start at the same time. NIP-CL gets a "Choosing
one channel" section: a client that needs one channel per creator and
label looks it up with `#P` + `#t`, creates it only if none exists, and
otherwise uses the oldest one (the lowest `created_at` tag, then the
lowest channel ID). Every reader that follows this rule picks the same
channel, even after an edit.

### Testing
- Relay test: many channels, one match, small `limit`. The request
returns the match for both `#t` and `#P`. This test fails without the
change.
- Unit test: `#t` and `#P` reach the database query only for
channel-state kinds.
- Relay test: one creator sends two creates for the same label at once.
Both channels exist, a `#P` + `#t` lookup finds both, and the
oldest-channel rule picks the same one in either order, even after the
older channel's metadata is re-published by an edit.

### Stack
These are two stacks. Merge them in this order. Client support
(creating, labeling and finding these channels) will be in
block/buzz-app, not the buzz SDK and CLI.

2f79374f48 feat(relay): channel labels (#8175)
🤖
## Summary
A plugin or agent often needs to tag its own channels and then find them
again, for example "my attention-config channel" or "all channels of
this workspace". Today a channel has no labels: the relay ignores any
`t` tags in create or edit requests. This PR adds channel labels.

- A create request can carry up to 8 labels as `["t", "<label>"]` tags.
- An edit request with `t` tags replaces the label set. `["t", ""]`
alone clears it, the same convention as `["ttl", ""]`. Only owners and
admins can change labels, as for the name.
- The relay publishes each label as a `t` tag on the channel's state
events, after the channel type tag.

Part 2 of 3, stacked on part 1.

### Related issue
None found.

### Details
- **Rules.** A label uses 1–64 characters from `a-z`, `0-9`, `.`, `:`
and `-`. The relay refuses a label equal to a channel type name
(`stream`, `forum`, `dm`, `workflow`, `system`), so a label cannot make
a channel look like another type.
- **No trust from labels.** Any admin can set a label. Only the
relay-written creator tag (part 1) says who made a channel.
- **Storage.** New migration `0061_channel_labels.sql` adds
`channels.labels TEXT[] NOT NULL DEFAULT '{}'`. Channels without labels
look and behave as before.
- **Readers.** The CLI and `buzz-acp` read the channel type from the
first `t` tag. Before this PR they used the last one, which would now be
a label.
- **Spec.** NIP-CL gets a "Channel labels" section with these rules.

### Testing
- Relay tests: labels at creation appear after the type tag, edit
replaces and clears them, invalid labels are refused, and members who
are not admins cannot change them.
- Unit tests for the label rules: allowed characters, length, reserved
type names, the 8-label cap and the clear marker.
- `buzz-acp` test: the channel type comes from the first `t` tag, not a
label.

### Stack
These are two stacks. Merge them in this order. Client support
(creating, labeling and finding these channels) will be in
block/buzz-app, not the buzz SDK and CLI.

**Stack 1: channel labels and creator lookup (#8174–#8176)**

1. #8174 channel type and creator tags, and the channel creation time
2. #8175 channel labels ← this PR
3. #8176 database-side label and creator match, and the rule for
choosing one channel

**Stack 2: system channels (#8180–#8182)**, stacked on stack 1 because
it uses labels and the creator tag

4. #8180 the system channel type
5. #8181 leave system channels out of reads that do not name them
6. #8182 channel-state filters opt in to system channels

b3795236cc fix(relay): reject unreadable write targets as missing (#8249)
🤖 A sender who cannot use or read a referenced event, artifact or
workflow now gets exactly the response it would get for an ID that does
not exist. #8197 (merged) set this rule for deletions; this applies it
to the other writes that look up a target, plus the workflow read and
webhook endpoints. Artifact `create` and workflow definition saves are
the exceptions, described below. Access is checked before any message
that depends on the target, readability goes through
`event_visible_to_reader` (including #8197's private-deletion rule), and
soft-deleted targets keep matching missing ones.

| Path | Checks, in order | Response for any unusable target |
|---|---|---|
| Reaction (kind 7) | target lookup → `event_visible_to_reader` → every
channel gate for the derived channel, including archived | `invalid:
reaction target event not found` |
| Edit (kind 40003) | target in the edit's `h` channel and readable →
author / agent-owner check, including an author since removed from a
private channel | `invalid: edit target not found or not editable by
you` |
| Forum vote (kind 45002) | target in the vote's `h` channel and
readable → kind check | `invalid: vote target event not found` |
| Report by event (kind 1984 `e`) | `event_visible_to_reader` → token
channel scope → channel membership or open | `invalid: report target
event not found` |
| Reply (NIP-10 and workflow `send_message` replies) | parent in the
reply's channel and readable | `reply parent not found` |
| Artifact update / delete / restore / move | head exists and is homed
in `h` (move: in the source the sender can write) → revision, type,
deleted and root checks | `conflict: artifact head unavailable` |
| Workflow trigger (kind 46020) | workflow exists and sender is its
owner | `invalid: workflow not found or not triggerable by you` |
| `GET /workflows/{id}/runs` and `/runs/{run_id}/approvals` | workflow
exists, has a channel, and the caller can read it | `404
{"error":"workflow not found"}` |
| `POST /hooks/{id}` | workflow exists and the provided secret matches
its stored secret → definition and trigger-type checks | `404
{"error":"workflow not found"}` |

Two of these reject writes that used to be accepted: a reaction to an
event the sender cannot read (such as someone else's author-only event),
and a report on an event the reporter cannot read. Reports by pubkey and
by blob are unchanged. In an archived channel, writes whose channel
comes from their target (reactions and deletions) get that target's
not-found response, and an artifact move out of an archived source
channel gets `conflict: artifact head unavailable` like any other source
the sender cannot write; every other write keeps `invalid: channel is
archived`. A webhook call with an absent or wrong secret, or to a
workflow without a webhook secret, now gets `404` instead of
`401`/`400`. Artifact `create` and workflow definition saves still
report a taken ID, as NIP-AR allows for artifacts.

Removed messages, none of which any client depends on from these
endpoints: `edit target event not found`, `must be event author to
edit`, `target event belongs to a different channel`, `target event has
no channel`, `parent event belongs to a different channel`, `parent
event has no channel association`, `artifact home changed`, `workflow is
not accessible`, `workflow is not channel-scoped`, the webhook's
`authentication failed` and `webhook secret required but not
configured`, `forbidden: not authorized to trigger this workflow` for
non-owners (it remains for an owner whose channel authority lapsed), and
`restricted: not a channel member` for an edit by an author removed from
a private channel.

`e2e_existence_oracle` checks each event write over HTTP and WS, and the
workflow read and webhook endpoints over HTTP, against missing,
soft-deleted, other-channel, private-channel, archived, author-only and
wrong-kind targets as applicable, with a positive control per path. It
runs in the Backend Integration job alongside
`e2e_author_only_deletion`. `removed_author_edit_does_not_reveal_target`
checks that a removed author's edits of their remaining message, their
deleted message and a missing ID get identical answers. In the
PostgreSQL suite, `head_outside_authorized_channel_matches_missing_head`
covers the artifact transaction,
`workflow_reply_to_unusable_parent_matches_missing` covers workflow
replies through `RelayActionSink::send_message`,
`scoped_token_report_does_not_reveal_target` and
`scoped_token_reaction_does_not_reveal_target` cover channel-scoped
tokens, and `channelless_workflow_runs_read_as_missing` covers the runs
read for a workflow with no channel.

ea24a3ee3d fix(ci): remove Detect Changed Paths timeout and deletion test race (#8300)
🤖
## Summary
This PR removes two CI flakes that failed relay-stack runs on
2026-10-13. Both passed when rerun.

- **Detect Changed Paths timeout.** This first CI job had a 2-minute
limit. Its steps take about 75 seconds, but GitHub sometimes finishes
the job minutes after the last step. In three runs, every step had
finished, but GitHub still cancelled the job at the limit, and all later
jobs failed. The limit is now 10 minutes.
- **PostgreSQL deletion test.**
`approval_boundary_blocks_claim_until_exact_inventory_is_approved`
sometimes could not claim an approved deletion request. This was a race
in the test, not a product bug.

How the test race happens:
- The test sends an UPDATE that the database must reject. Then it claims
the same row. PostgreSQL sends the error to the client before it rolls
back the statement and releases its row lock. sqlx returns as soon as it
gets the error.
- The claim runs on another pooled connection with `FOR UPDATE ... SKIP
LOCKED`. It can skip the row while the lock is still held, and return no
claim.
- The test now runs the rejected UPDATE on its own connection. Then it
sends `SELECT 1` on that connection before it claims. That round trip
completes only after PostgreSQL has finished the rollback.

Production code does not change. A claim that skips a row locked by
another transaction is correct behavior. I checked the other tests in
this file. Only this test has a rejected write on the request row
immediately before a `SKIP LOCKED` claim. In the other tests, a blocking
`approve` call runs before the claim.

### Related issue
N/A. No existing PR found. Failing runs: [timeout
#8174](https://github.com/block/buzz/actions/runs/38468285648/job/115540525751),

[deletion test
#8182](https://github.com/block/buzz/actions/runs/38468329504/job/115550003726).

### Testing
- I confirmed the order in the PostgreSQL 17 source: `EmitErrorReport()`
(which flushes to the client) runs before `AbortCurrentTransaction()` in
`tcop/postgres.c`. A BEFORE UPDATE trigger locks the row first
(`GetTupleForTrigger` in `commands/trigger.c`).
- I could not reproduce the failure locally: 0 failures in 410 runs,
including runs on a CPU-limited PostgreSQL container. The fixed test
passes against PostgreSQL 17.

2270b66e14 test(buzz-db): drop partition scratch schemas on panic (#8293)
## Summary

The partition Postgres tests dropped their scratch schema with a
`drop_schema` call at the end of each test body. When a test panicked,
that call never ran, so the schema leaked into the shared database,
along with any `{schema}_*` sibling schemas or reader role the test
created. A reviewer on #7993 hit this locally: the leaked schema plus a
database-wide catalog query made later runs fail. CI hides it because
the test wrapper gives each process its own database.

`scratch_pool` / `scratch_pool_with_max_connections` now return `(pool,
ScratchSchema)`. The guard owns the admin pool and schema name and
cleans up on `Drop`:

- **Fresh thread and connection.** `Drop` runs on the test's runtime
thread, which can't drive the test's pools while it blocks, so cleanup
runs on its own thread with its own runtime and connection.
- **Terminates the test's backends first.** Both pools record each
connection's backend pid. A test that panics mid-transaction keeps its
locks, because the rollback would only run on the blocked runtime.
Without this step `DROP SCHEMA` waits on those locks.
- **Drops `{name}` plus every schema and role named `{name}_*`.** This
replaces the per-test sibling-schema and `DROP ROLE` cleanup. The reader
role is now named `{schema}_reader`.
- **Bounded.** `lock_timeout = '10s'`. Failures print a warning and
never panic inside `Drop`.

The 52 call sites are migrated mechanically. Test-only change.

### Related issue

Follow-up from review on #7993. No existing issue found.

### Testing

- New `scratch_schema_is_dropped_when_a_test_panics_holding_a_lock`: the
test body creates a sibling schema, takes `ACCESS EXCLUSIVE` on a
scratch table in an open transaction, and panics. The test then asserts
no `{name}` / `{name}_*` schema remains.
- Proved it can fail: with the backend-termination step disabled,
cleanup hits the lock timeout and the test fails, reporting both leaked
schemas.
- Partition Postgres lane: `scripts/postgres-test-run.sh -p buzz-db
--lib -E 'test(partition)'`, 53/53 passed.
- The same filter run directly against the shared `buzz` database: 53/53
passed, then 0 `partition_audit_test_%` schemas and 0
`partition_audit_%` roles remained.
- `cargo clippy -p buzz-db --tests` clean. Pre-push hooks passed.

d25384a4f3 buzz-db: admit every fenced-table writer in app code (#8219)
## Summary

This makes every serving writer of a community-write-fenced table take
community admission in application code. That's the "Dual enforcement"
step of the Supported Writer Contract in `ARCHITECTURE.md`. Admission
means the shared community deletion lock plus the active/not-deleted
check from `deletion::guard_community_write`. It's taken before the
transaction's first tenant write or row lock and held until commit.

The 32 `community_write_fence_*` triggers, the six fence SQL functions
and `validate_serving_catalog` are unchanged. They stay authoritative.
Removing them is a separate migration that will be checked table by
table.

## Changes

- **New admission entry point.** `begin_community_write_transaction`
(`runtime/mod.rs`) builds an `AdmittedTx` for non-event writers. It sits
next to the existing event-write entry points and shares their
implementation.
- **Writers moved onto it:**
- `api_tokens`, `archived_identities`, `channels`, `channel_members`
(including DM and admin paths), `community_bans`, `git_repo_names`
- `moderation_actions` and `moderation_reports`,
`personal_read_accounts` and `personal_read_frontiers`,
`pubkey_allowlist`
  - `push_leases`, `push_match_queue`, `push_wake_outbox`
- `relay_invites`, `relay_members` (including the new-community owner
bootstrap and the startup `pubkey_allowlist` backfill),
`join_policy_acceptances`
- `thread_metadata`, `users`, `workflows`, `workflow_runs`,
`workflow_approvals`, `scheduled_workflow_fires`
  - Personal-read helpers now require `&mut AdmittedTx`.
- **`buzz-audit`.** An append now passes admission first, then takes a
transaction-scoped audit-chain lock (`pg_advisory_xact_lock`). This
replaces the session lock and the `catch_unwind` unlock cleanup. The
relay audit worker retries a `lock_timeout` on either lock and keeps the
entry; an admission refusal is terminal, as the trigger's refusal was.
- **Fleet-wide statements.** These keep `community_write_allowed(...)`
in the same SQL statement, because there's no single community to admit
up front:
  - scheduled-fire prune
  - invite expiry
  - push matcher claim and exhausted-job cleanup
  - startup `d_tag` backfill
  - channel TTL cleanup
- **Relay-member removal.** `remove_relay_member` and
`remove_relay_member_if_role` run `delete_member_with_acceptances`
inside their admitted transaction. The helper no longer opens its own
transaction, so the member lock, the `join_policy_acceptances` delete
and the member delete all hold admission until commit. `delete_workflow`
and `delete_workflow_for_owner` are gone on `main`, and the coordinate
deletion path they used to back was already admitted.
- **Unchanged exceptions.** The deletion-executor generation exception
and the serving-lease path work as before.
- **Tables with no production writer.** `delivery_log` and
`subscriptions` are only written by a historical cutover script and a
test fixture. Their triggers stay.
- **No cross-community moves.** No production `community_id` move exists
on a fenced table. The only `SET community_id = NULL` is the
deletion-executor purge. So no dual-community lock ordering was needed.

## What got simpler

- Per-store ad-hoc writer helpers are gone:
`begin_event_write_transaction` and `acquire_event_write_connection` in
`channel.rs`, and `begin_operation_transaction` in `push.rs`.
- Audit append drops the session advisory unlock, the
`catch_unwind`/`resume_unwind` panic handling, `log_inner` and the
`futures-util` dependency.

## Notes for reviewers

- **New crate dependency.** `buzz-audit` now depends on `buzz-db` only
to call the free function `buzz_db::deletion::guard_community_write`.
`ARCHITECTURE.md` names this as the one sanctioned subsystem edge, and
its audit section is updated to match.
- **Hot paths.** `ensure_user` first checks whether the user exists and
returns without admission when it does (no write happens). Only a real
insert takes admission. `touch_api_token` has no production caller
today.
- **No-op writers stay read-only.** The startup allowlist backfill
returns early on plain reads when the legacy table is gone, it has no
rows for the community, or the community already has members, so a
quiescing deployment community still starts. It re-checks under
admission before inserting.
- **Owner mutations.** When admission refuses a transfer or a
provisioning and a deletion request exists, both report
`DeletionPending`, as before. For a transfer, the operator API keeps its
coded `deletion_lifecycle_conflict` 409. For provisioning, it keeps the
existing uncoded 409, `owner_conflict: community deletion is pending`.
- **Per-community worker loops.** `claim_due_push_wakes` and similar now
return `AccessDenied` for a community that goes quiescing between the
active-host scan and the claim. The worker logs it at `debug` and the
next scan skips the community.
- **Kick side effects.** `membership_removal_fence` admits before the
membership lock to keep the lock order of `add_member`. A community that
leaves `active` between the kick and the fence skips live subscription
eviction; the membership cache is already invalidated and fan-out
re-checks membership. This is documented on the function.

## Testing

- **New refusal tests.** 19 tests: the 18 in
`store::admission_postgres_tests`, plus
`audit_append_requires_application_admission_with_triggers_bypassed`.
Each runs with ordinary triggers disabled (`session_replication_role =
replica`), checks that a raw fenced insert would succeed, and asserts
that the writer is refused for both `quiescing` and `fenced`
communities. Active writes still succeed.
- **The tests catch a missing check.** Measured in review at
`6fc073c3f`: with the guard in `AdmittedTx::admit` bypassed, 25 tests
fail. That includes 16 of the 18 database admission tests. The audit
test stays green there, because audit calls `guard_community_write`
directly.
- **Affected PG suites, with triggers on:** 183/183 passed across 16
store suites, push 18/18 run isolated, audit 7/7. The existing artifact,
reaction and replaceable admission tests pass.
- **Review fixes, each checked to fail without its fix:**
- `allowlist_backfill_requires_application_admission` and
`owner_mutations_report_pending_deletion_when_admission_refuses` fail
with the old `relay_members.rs`.
- `empty_allowlist_backfill_skips_admission` fails (`AccessDenied …
write-fenced (quiescing)`) without the allowlist-rows early return.
-
`audit_worker_retries_admission_lock_timeout_until_original_entry_is_appended_once`
holds the community deletion lock exclusive and fails without the
admission retry arm.
- The existing audit-chain retry test now looks for the
transaction-scoped lock and passes.
- The two owner-revoke mini-schema tests (`bridge.rs`, `ingest.rs`) now
include `communities` and `community_deletion_lock_key`, which admission
reads; both failed without that.
- **Static checks:** `cargo fmt --check` and workspace `cargo clippy
--all-targets -D warnings` pass.
- **Not run locally:** the `mobile-check` step of `just ci` (the build
machine couldn't reach pub.dev, and clean base fails the same way) and
the full `just test` lane. CI on this PR covers both.
`mesh_demo::demo_join_forwarded_arm_round_trips_echo` fails on the build
machine at base `394d4a434` as well; it uses no database.

8bb49a1b6a feat(relay): publish channel type and creator on every channel-state event (#8174)
🤖
## Summary
Clients cannot tell who created a channel, and only the channel-metadata
event says what type of channel it is. This PR makes every relay-signed
channel-state event carry both facts, so a client can find "the channel
that this key created" with one ordinary Nostr filter.

- Channel metadata, admin list and member list events (kinds 39000,
39001 and 39002) now all carry the channel type as their first `t` tag,
then the creator as a `P` tag.
- The creator comes from the relay's own record of who signed the
channel's create request. No client can set it, and it does not change
when ownership moves.
- Channel metadata (kind:39000) also carries `["created_at", <unix
seconds>]`, the time the channel was created. The event's own
`created_at` changes on every edit, so before this a client could not
tell which of two channels is older.

This is part 1 of a 3-part stack (channel labels and creator lookup).
The system channels stack (#8180–#8182) builds on it.

### Related issue
None found.

### Details
- **Why `P`.** Several Nostr specs (NIP-22, NIP-34, NIP-72) use
uppercase `P` for the author of the root object, and lowercase `p` for
people involved. Lowercase `p` is already used on these events for
members and DM participants, and a filter matches tag values, not their
meaning, so `#p` would mix them.
- **Trust.** A client that trusts a channel because of its creator must
also check that the relay key signed the event.
- **Order.** The type `t` tag comes first, so clients that read the
first `t` tag still get the type after part 2 adds labels as more `t`
tags.
- **Creation time.** The relay reads it from `channels.created_at`, so
an edit does not change it. #8176 uses it to pick one channel when two
creates race.
- `buzz-admin reconcile` writes the same tags when it rebuilds these
events. `NOSTR.md` documents the tags.
- **Spec.** New `docs/nips/NIP-CL.md` defines these tags, the trust rule
and lookup by creator. Later PRs in both stacks add their parts to it.
`NOSTR.md` links to it.

### Testing
- Relay tests in `group_state_postgres_tests.rs`: each of the three
kinds carries the type first, then the creator; the creator stays the
same after an ownership transfer; kind:39000 carries the stored creation
time, and still does after an edit.
- Unit test for the shared tag builder that both the relay and
`buzz-admin reconcile` use.

### Stack
These are two stacks. Merge them in this order. Client support
(creating, labeling and finding these channels) will be in
block/buzz-app, not the buzz SDK and CLI.

**Stack 1: channel labels and creator lookup (#8174–#8176)**

1. #8174 channel type and creator tags, and the channel creation time ←
this PR
2. #8175 channel labels
3. #8176 database-side label and creator match, and the rule for
choosing one channel

**Stack 2: system channels (#8180–#8182)**, stacked on stack 1 because
it uses labels and the creator tag

4. #8180 the system channel type
5. #8181 leave system channels out of reads that do not name them
6. #8182 channel-state filters opt in to system channels

52d13efc08 fix(buzz-db): delete workflow and membership children explicitly (#8212)
## What

Workflow deletion and relay-member removal relied on `ON DELETE CASCADE`
to remove child rows. Both paths now delete their own children inside
the same transaction, so a later migration can drop those foreign-key
actions without changing behavior.

**Workflow deletion** (`store/workflow/deletion.rs`, the coordinate path
used by NIP-09 deletes of workflow definitions):
- Locks the target workflow row with `SELECT … FOR UPDATE`, under the
same owner and coordinate predicate as before. A concurrent run or fire
insert has to lock that row for its foreign key, so the child deletes
see every committed child.
- Deletes scheduled fires first. A new fire has to lock the workflow
row, and a cron attach locks the fire before the run, so deleting fires
before the run lock keeps the lock order consistent and avoids a
deadlock.
- Then locks the workflow's runs `FOR UPDATE` in `id` order. An approval
that names another workflow but references one of these runs key-share
locks only the run, so the workflow lock alone doesn't exclude it.
- `delete_workflow_with_children` then deletes approvals (for the
workflow or any of its runs), then runs, then the workflow, and returns
its `channel_id`.

**Relay-member removal** (`store/relay_members.rs`):
`remove_relay_member` and `remove_relay_member_if_role` share a new
`delete_member_with_acceptances` helper. It locks the member row under
the existing predicate (any non-owner, or an exact role), deletes
`join_policy_acceptances`, then deletes the member, in one transaction.
The `RemoveResult` outcomes are unchanged.

**Removed:** `delete_workflow` (no callers) and
`delete_workflow_for_owner` (test-only), plus their `Db` wrappers. The
community-confinement test now drives the production coordinate
deletion.

## Tests

- `test_support::retire_foreign_key_delete_actions` rewrites every
`CASCADE`, `SET NULL` and `SET DEFAULT` foreign key in the test's own
per-test database as `NO ACTION`, which is the target schema of the
follow-up migration. It asserts that none remain. All triggers stay
live, including foreign-key checks and the community write fence. It
refuses to run unless `current_database()` has the per-test wrapper's
exact shape (`buzz_nt_` plus 24 hex digits), which excludes the run's
`_desired` template. It checks the name only.
- `workflow_deletion_removes_children_without_cascades` and
`member_removal_deletes_acceptances_without_cascades` run the production
paths on that schema and require every child row to be gone. One
approval references another workflow but this workflow's run, which pins
the `run_id` branch. The owner, role-mismatch and not-found outcomes
still hold.
- `workflow_deletion_waits_for_and_removes_concurrent_run` and
`member_removal_waits_for_and_removes_concurrent_acceptance` hold a
child insert open in a second transaction, wait until the removal is
blocked on a lock, and then commit. The removal must succeed with no
children left.
- `workflow_deletion_waits_for_concurrent_fire_attach_without_deadlock`
holds a fire row the way the cron attach does, then attaches a run to it
while the deletion waits. Both must succeed.
-
`workflow_deletion_waits_for_and_removes_concurrent_cross_workflow_approval`
does the same with an approval for another workflow that references this
workflow's run.
- The bridge test schema now includes `join_policy_acceptances`.

## What got simpler

Two delete paths no longer depend on implicit constraint actions, and
two unused workflow-delete functions are gone. This is the first step of
retiring the `CASCADE` and `SET NULL` foreign keys.

**Identified debt (later PRs):** `channel_members` and
`personal_read_frontiers` (no hard-delete path found yet for their
parents), the deletion `manifest_keys` cascade, the `SET NULL` actions
on `executor_heartbeats` and `product_feedback`, and the `users`
self-reference. That last one is a composite `(community_id,
agent_owner_pubkey)` `ON DELETE SET NULL` that would try to null the
`NOT NULL` `community_id`. Also, a scheduled fire for workflow B can
link to a run of A (that FK is already `NO ACTION`), which would block
A's run delete; the scheduler always attaches a run to its own
workflow's fire, so this needs same-workflow enforcement in the cascade
work.

## Verification

Head `081be4c0d`, tree `ab649487`, on a Linux cloud workstation: fmt,
buzz-db and workspace clippy, source policy and buzz-db lib pass; the
six new tests pass; buzz-db PostgreSQL passes 490/490 and buzz-relay
PostgreSQL 378/378. A sixth mutation, moving the fire delete back after
the run lock, makes
`workflow_deletion_waits_for_concurrent_fire_attach_without_deadlock`
fail with `40P01` (deadlock detected).

Previous head:

Head `787c7c42d`, tree `6b9cf5d5`, on a Linux cloud workstation: fmt,
buzz-db and workspace clippy, source policy and buzz-db lib pass; the
new tests pass 5/5; buzz-relay PostgreSQL passes 378/378; buzz-db
PostgreSQL passes 488/489, the one failure being
`parent_contention_times_out_without_blocking_the_other_table` in
`store/partition/`, which this PR doesn't touch and which passes on its
own at the same tree. A fifth mutation, removing the run lock, makes the
new cross-workflow approval test fail with the reviewer's exact 23503 on
`workflow_approvals_community_id_run_id_fkey`.

Previous head `00cba2f4a`, tree `2f89fed4`, base `e9269cbdf`. Results
from a Linux cloud workstation:
- fmt, buzz-db and workspace clippy, the source policy and buzz-db lib
all pass.
- The buzz-db PostgreSQL suite passes 488/488.
- The buzz-relay PostgreSQL suite passes 378/378.

Each of four mutations makes exactly one of the new tests fail with the
foreign-key violation you'd expect (23503):
- swapping the fires and runs deletes
- deleting approvals by `workflow_id` only
- removing the workflow row lock
- removing the member row lock

GitHub CI is green at this head.

8599efb6a3 feat(relay): allow HTTP operator listener delivery URLs (#8287)
## Summary

Operator listener configuration currently rejects HTTP URLs, preventing
delivery to sibling services over internal HTTP connections. Accept HTTP
and HTTPS delivery URLs while retaining the existing pubkey,
duplicate-route, and URL restrictions.

Add configuration coverage for internal hostnames and custom ports,
verify signed delivery through the real HTTP client, and include the
listener suite in both unit-test runners. Shared NIP-98 signing and push
gateway code are unchanged.

### Related issue

Related: #7934 refactors operator listener delivery tests. No matching
open issue found.

### Testing

- `cargo test -p buzz-relay --lib operator_listener`: 13 passed,
including signed HTTP delivery and redirect rejection.
- `cargo fmt --all -- --check`, shell syntax, Justfile parsing, and diff
whitespace checks passed.
- `just test`: passed.
- `just ci`: stopped at mobile analysis with an existing undefined
`buzzDevPushAppProfile` in
`mobile/test/features/settings/notification_toggle_test.dart:81`.
Workspace and native desktop formatting/Clippy, desktop frontend checks,
and web checks passed. The mobile file is unchanged by this PR.

Locally verified with a spiked listener client

85b7331784 fix(relay): partition audit observability follow-ups (#7994)
> [!IMPORTANT]
> **The alert rules changed in c3a314e71.** If you reviewed the alert
guidance earlier, please look again.
> - **The two range-based rules now apply only to live pods.** A range
selector such as `[30m]` keeps reading a terminated pod's samples until
they leave the window. So `BuzzPartitionAuditNotRunning` could fire for
about 10 minutes after normal pod turnover, and
`BuzzPartitionAuditFailing` could keep firing for up to an hour after
the pod was gone. Each rule now adds `and <counter>`, which requires the
counter to be exported right now:
>   ```yaml
>   expr: |
> sum without (outcome) (increase(buzz_partition_audit_runs_total[30m]))
== 0
>       and sum without (outcome) (buzz_partition_audit_runs_total)
>   ```
>   ```yaml
>   expr: |
>     increase(buzz_partition_audit_failures_total[1h]) >= 2
>       and buzz_partition_audit_failures_total
>   ```
> - **The audit counters start at 0.** When the relay starts, it exports
every `buzz_partition_audit_runs_total{table, outcome}` series and
`buzz_partition_audit_failures_total` at 0, before the first audit.
`increase()` ignores a new series' first sample. Before this change, it
could miss the first periodic failure, or read a table's first
`degraded` run as a stopped loop. This change is also what makes the
`and <counter>` gate work: the counters now exist for a relay's whole
life.
>
> The doc's old claim that pod turnover can't leave an alert firing was
true only of the instant-selector stale rule. The doc now explains the
difference.

## Why

These are the observability follow-ups deferred from #6515 ("fix(db):
audit partition catalog before creation"):

- **Timestamp-age alerts go silent** ([review
comment](https://github.com/block/buzz/pull/6515#discussion_r4127212141)).
Partition gauges are set only when a table audits successfully, and the
exporter evicts idle gauges after 2,700 s by default. After sustained
failures, `buzz_partition_audit_last_success_timestamp_seconds`
disappears. A table that has never audited successfully never has it. An
alert on `time() - last_success` then has no input.
- **Startup fallback failures are not counted** ([review
comment](https://github.com/block/buzz/pull/6515#discussion_r4127212158)).
When the startup fallback audit fails, it logs an error but does not
increment `buzz_partition_audit_failures_total`. Periodic failures do.
- **Repaired environments are always `degraded`**.
`PartitionTableAudit::degraded()` counts every legacy leaf, even one
wholly in the past. The `bb-block-staging` audit of the repaired catalog
reports `degraded` only because of `events_p2026_07_08_legacy`
`[2026-07-01, 2026-09-01)`. With this rule, every repaired environment
stays `degraded`, so nobody can alert on the outcome.
- **Partition config tests can see a poisoned env** ([review
comment](https://github.com/block/buzz/pull/6515#discussion_r4137416297)).
Two partition config tests take only `ENV_MUTEX`. A NIP-FI test running
in the same process can make them see its deliberately invalid
environment.

Partition health is still diagnostic only, through
`/_status.partition_catalog` and metrics. Nothing here affects
`/_readiness`. Handling concurrent creation (#6515 item 4) is out of
scope and stays with the catch-all advancement work.

## What

- **Success timestamp survives failures.** Each failed table audit
refreshes `buzz_partition_audit_last_success_timestamp_seconds` with
`increment(0.0)`, which leaves the value unchanged. It still resets the
exporter's idle tracking, the same mechanism as
`refresh_legacy_active_gauge_recency`. Sustained failures therefore keep
the last success exported and its age rising. A table that has never
succeeded exports `0`. A failed audit still never makes the last success
look fresh.
- **Alert guidance.** New `docs/partition-catalog-monitoring.md` covers
the metrics, how long each series lives, and the audit outcomes. It
notes that `runs_total` has no `unsafe` outcome. It gives three alert
rules:
- timestamp age, which also covers never-successful tables and sustained
failures;
- `sum without (outcome)
(increase(buzz_partition_audit_runs_total[30m])) == 0` for a stopped
audit loop. Counters are never idle-evicted, and this rule fires before
the stopped loop's timestamp is evicted, so there is no false resolve;
  - an aggregate failure-counter rule.

Both range-based rules also require their counter to be exported right
now (`and <counter>`), so a terminated pod's leftover samples can't
raise or hold an alert.
- **Zero counter baselines.** `try_install` exports each
`buzz_partition_audit_runs_total{table, outcome}` series (`ok`,
`degraded`, and `error` for both tables) and
`buzz_partition_audit_failures_total` at 0 before the startup audit, the
same way the auth series already start at 0. A failure in the startup
audit itself can still happen before the first scrape. The doc says so;
the stale rule covers that case.
- **Failure counter.** `buzz_partition_audit_failures_total` now counts
failed explicit audit attempts: the startup fallback audit and each
periodic audit. Both paths go through one helper,
`counted_partition_audit`. A failed `ensure_future_partitions` call,
such as a DDL error that the fallback then recovers, is not counted by
itself. A single attempt never counts twice.
- **Historical legacy leaves.** A legacy leaf is historical when its
finite upper bound is at or before the current month start. It is still
reported under `children` as `legacy_leaf`, but it no longer degrades
the table. A legacy leaf that still covers the current month or any
lookahead month stays degraded. All other degradation causes are
unchanged. The verdict now lives in `PartitionAuditReport::outcome()`,
which `buzz-admin partition-audit` uses. The JSON outcome names and exit
codes are the same as before.
- **Test hygiene.** Both partition config tests now use `env_guards()`.

## How it was tested

- `cargo fmt --all -- --check` and `cargo clippy -p buzz-db -p
buzz-relay -p buzz-admin --all-targets -- -D warnings`.
- New unit tests:
- The repaired incident layout with an injected clock: `degraded` in
August 2026 and `ok` on 2026-09-01T00:00Z, when the upper bound equals
the current month start, and on 2026-09-15. The legacy leaf is still in
the serialized report. The `outcome` label on the run counter follows
the verdict.
- A table test of the legacy-leaf predicate: the upper bound before, at,
and one second after the month start; lookahead and beyond-horizon
leaves; historical leaves with trigger drift; anomalous and `DEFAULT`
children; no audited month.
- Outcome precedence (error, then unsafe, then degraded) and the
`buzz-admin` exit-code mapping.
- Startup: a failed fallback counts once, a successful fallback after a
DDL failure counts nothing, and a successful ensure never runs the
fallback. Each periodic failure counts once. Against an unreachable
database, startup counts one aggregate failure while each table still
records two `error` runs.
- On the production exporter, never-successful audits leave run counters
and a `0` success timestamp for both tables.
- On the production exporter, all six run-counter series and the failure
counter read 0 before any audit. After one failed audit, `error` reads 1
and `ok`/`degraded` stay at 0. Removing the initialization fails this
test.
- PostgreSQL lane (`scripts/postgres-test-run.sh`) with new or extended
tests:
- The repaired layout is not degraded in September. The same catalog is
degraded in August.
- With a 1 s idle timeout, a failed audit leaves the success timestamp
unchanged, and sustained failures keep it exported past the idle
timeout. When audits stop, the timestamp is evicted but the run counters
remain. The next success exports a fresh timestamp.
- Mutation check: removing the failure-path refresh fails both alert
fixtures.
- These fixtures check the emitted series. They do not evaluate the
rules themselves, including the `and <counter>` gate. `promtool` isn't
available locally or in CI, and the doc points to `promtool test rules`
for that.
- `scripts/test-postgres-test-discovery.sh`.
- `config::` and `nip_fi_config::` tests run together in one process
five times.
