fix(db): keep lease releases durable and deflake PostgreSQL lane tests (#8676)
## Summary
When the user-deletion worker dropped a lease heartbeat, its pooled
connection could be left inside an open transaction. The worker's final
lease `release` then reported success but never committed, and a rerun
saw the request as "leased by another worker" for up to 60 s. The
heartbeat is now one autocommit `UPDATE`.
The PR also fixes six PostgreSQL-lane test flakes from the 21–28 Oct
2026 CI audit. It moves one relay test off the 100 ms-acquire test
helper before that test starts flaking the same way.
This is one of seven PRs split out of the `flakey-tests` branch
(siblings below). It touches only `buzz-db`, `buzz-deletion` and
`buzz-relay`. Every relay file except `connection.rs` and
`boot_lifecycle.rs` changes only for the helper rename in the last row.

test: dedupe collect_until_eose by event id and uncap two shell tests (#8677)
## Summary Fixes two CI flakes from the 21–28 Oct 2026 audit, both in test code with no product change: - The relay E2E helper `collect_until_eose` now drops repeat copies of an event id. - Two Windows shell tests drop a 5 s cap that a cold Git Bash start can exceed. This is one of seven PRs split out of the `flakey-tests` branch (siblings below). ### Related issue None found for these two. The buzz-terminal `passwd_shell()` `getpwuid` race (`env_fence_tests::resolve_shell_falls_through_to_passwd_not_the_default`, run 38590095289) is left to open PR #7687, which already replaces `getpwuid`. #8636 and #7976 edit `buzz-test-client/src/lib.rs`, and #7607 and #7915 edit `buzz-dev-mcp/src/shell.rs`, but none of them changes `collect_until_eose` or these timeouts. ### Flaky tests fixed | Test | Failing runs | Cause | Change | |---|---|---|---| | Relay E2E `e2e_project::test_project_tombstone_deletes_coordinate_and_spares_members` (e2e_project.rs:338, "left: 2 right: 1") | 40408678412#1, job 121879630394 (PR #8620, schema-only) | The EVENT handler sends OK, then fans out in a spawned task. `handle_req` registers the live subscription before its history query, and `req.rs`'s `seen_ids` dedups history rows only. If fan-out runs after the REQ is registered, the event arrives once live and once from history, both before EOSE, and `collect_until_eose` kept every frame. | `collect_until_eose` keeps the first copy of each event id, as production clients do. Its doc comment says a test of the relay's own dedup must read frames with `recv_event`. A new unit test, `collect_until_eose_keeps_one_copy_of_each_event_id`, uses a fake relay that sends the duplicate. | | Windows `buzz-dev-mcp` `shell::tests::basic_echo` (shell.rs:1026, exit 124) | 39675698081#1, job 119485363399 (green on re-run) | 124 is the shell tool's own timeout exit code. `basic_echo` capped the shell at 5 s, and it is one of the first tests in the process to start Git Bash, which can take longer than 5 s on a cold runner. | `timeout_ms: None` (the production 120 s default) in `basic_echo` and in `workdir_is_honored`, which has the same exposure. `timeout_fires` still covers timeouts. | Pre-check: no e2e test relies on the relay's own history dedup. Every exact-count assertion uses a single filter. The NIP-33 "only newest remains" assertions would see a failed replacement as two different ids, and this dedup keeps both. Local evidence is from the original `flakey-tests` commit (fc4518d39): - The new unit test: FAIL before, PASS after. - 13 of the 14 e2e files that call the helper, plus `e2e_thread_roots`, against an isolated local relay. All pass, except `e2e_relay` `test_unarchive_emits_member_added_notification`. That test fails by itself 3/5 with the original helper too, and CI's Relay E2E lane doesn't select it. - The Windows failure can't be reproduced on macOS. The Windows Rust lane is the check. Follow-up (out of scope): make the relay deliver each event id at most once per subscription, keeping the live/history overlap. ### Verification This branch was pushed without local re-verification, by the user's choice: local test runs were overloading the machine and failing for that reason. **Hosted CI is the check.** It was pushed with `git push --no-verify`, because the pre-push hook runs clippy and unit tests. - Both files are byte-identical to their final versions on `flakey-tests` (67185df6a). - Checked for this PR: `git diff --check`, `rustfmt --check`, and a conflict-free merge with all six siblings onto `main`. ### Readiness Test-only change. AGENTS.md's readiness steps (agent review, then human confirmation) are still outstanding, so `buzz-review-completed` is not set. ### Merge order Independent of the other six. It merges cleanly onto `main`, and with every sibling, in any order. ### Sibling PRs Split from `flakey-tests` (one PR per area): #8676 (PostgreSQL lease + lane), #8678 (mobile), #8679 (Tauri apt cache + Windows Rust cap), #8680 (desktop product races), #8681 (desktop E2E state gates), #8682 (desktop E2E composer + row actions). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: Matt Toohey <contact@matttoohey.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

fix: don't notify workflow owners through their attribution tag (#8694)
A workflow message names its owner in a marked p tag, ["p", owner, "", "owner"], for attribution. #p live, history and push matching, operator listeners, desktop, mobile and the iOS NSE treat that tag as attribution rather than a mention. A workflow that mentions its owner adds a plain p, so the owner is notified only when actually mentioned. NOSTR.md records the #p exception.

perf(relay): cut connect-burst CPU in log filtering and open-channel lookup (#8670)
## Summary
A cold relay taking a burst of new connections spent most of its CPU on
two things that don't scale with useful work. This PR removes both.
**Log filtering held a contended lock.** `EnvFilter` (tracing-subscriber
0.3.23) takes a shared `RwLock` read on every span enter and exit, even
when no directive names a span. Every poll of an instrumented future
enters its span, and the relay installs two per-layer `EnvFilter`s (logs
and OTEL), so every worker contends on those locks. Plain `target=level`
directive lists now filter through
`tracing_subscriber::filter::Targets`, which keeps no per-span state.
Directives that name spans or fields still use `EnvFilter`, which is the
only filter that understands them.
**Each reader re-read the community's open channels.** A reader's
accessible channels are its member channels plus the community's listed
open channels, and the open half is the same for every reader. The
per-reader cache stored the union, so every miss fetched every open
channel row again. The lookup is now two cached halves:
- member channels, per reader, cached as before;
- open channels, once per community.
The shared half is used for a bounded time. Cross-pod invalidation is
best-effort, so a pod can miss the drop that follows a channel becoming
private, unlisted or deleted elsewhere. Each cached open set records
when its database read began, and readers use it only for
`OPEN_CHANNELS_MAX_AGE` (1 s) after that. After that the next reader
re-reads it. **Accepted trade-off:** if an invalidation is lost, any
reader on that pod can be granted a just-revoked open channel, history
included, for at most 1 s. That includes a reader with no cache entry,
which on `main` always read the database. This is a new exposure for
those readers. With no bound, the shared set could have served that
channel for its 10 s TTL. Readers with a cached entry already had a 10 s
window on `main`, so for them the bound is tighter than before. An exact
per-community version check would remove the window but needs a schema
change, so it's tracked as a follow-up.
Invalidations still drop the halves. A community-wide accessible-channel
or channel-deleted invalidation drops both halves, and a membership
invalidation drops only that reader's member half. The age bound counts
from the start of the read, so open-set fills need no fence: a fill that
raced a drop is still at most 1 s stale. Uncached callers of
`get_accessible_channel_ids` get the same set as before, now built from
the two halves. Open-set reads are counted by
`buzz_open_channels_cache_hits_total` and
`buzz_open_channels_cache_misses_total{reason="absent"|"expired"}`.
**Metric meaning change:** `buzz_accessible_channels_cache_hits_total`
and `buzz_accessible_channels_cache_misses_total` keep their names but
now count only the per-reader member half. Dashboards that read them as
whole-lookup hit rates should add the open-set counters above.
Empty levels (`target=`) stay on `EnvFilter`. `Targets` reads an empty
level as ERROR while `EnvFilter` reads it as TRACE, so only
`target=level` directives with a non-empty level take the `Targets`
path.
## Results
Measured with the relay load generator (#8636) on one Linux machine. The
relay ran as a release build on 8 pinned cores, with local Postgres,
Redis and MinIO; the generator ran on separate cores. The fixture is one
community with 2,000 open channels. Clients connect in a burst against a
cold relay: 48k WebSocket clients and 4.8k HTTP agents.
Each arm restored the same database snapshot and ran the same generator
binary and scenario. Arms were rotated (base/before/after, then
before/after/base, then after/base/before), and the table shows medians
of three runs per arm. Both columns after base also carry #8666, so the
comparison isolates this PR's design.
- **before** is this PR's first revision, which had an unbounded shared
open set.
- **after** is this head, where the open set is bounded to 1 s.
| | base | before | after |
|---|---|---|---|
| relay cores (mean) | 6.37 | 2.39 | 2.45 |
| connect p99 | 3,870 ms | 40 ms | 42 ms |
| subscribe EOSE p99 | 12,952 ms | 110 ms | 112 ms |
| history EOSE p99 | 1,252 ms | 68 ms | 72 ms |
| live delivery p99 | 26,421 ms | 54 ms | 55 ms |
| HTTP query p99 | 16,426 ms | 44 ms | 43 ms |
| DB tuples returned/s | 1.04M | 43k | 49k |
| DB transactions/s | 4,397 | 4,065 | 4,062 |
| relay RSS peak | 12.6 GB | 10.7 GB | 10.7 GB |
| errors | 16, plus 241k throttled | 0 | 0 |
The 1 s bound costs about 1,400 extra open-set reads per run, within
run-to-run noise of the unbounded version. One run in each of the two
right-hand arms had a slow tail (connect p99 0.8–1.3 s), which the
medians absorb.
An earlier revision bound the shared set to a per-reader digest instead.
That was exact, but in the same kind of A/B its per-miss digest query
returned about 28 times the tuples per second of the unbounded version.
It gave back the database savings, so this revision uses the time bound.
The open-channel gain scales with how many listed open channels a
community has. The filter gain doesn't depend on the fixture.
## Rollout
There's no flag, so the change takes effect on deploy. There's no schema
or data change, so reverting the commit is the rollback.
1. Deploy to staging and compare relay CPU and connect and EOSE p99
under a connection burst.
2. Watch `buzz_open_channels_cache_misses_total{reason="expired"}`.
Expect at most about one per second per active community per pod.
3. Confirm the deployed `RUST_LOG` and `BUZZ_OTEL_FILTER` are plain
`target=level` lists, so they take the `Targets` path. Other values fall
back to `EnvFilter` and keep today's cost.
## What got simpler
- `invalidate_channel_deleted_local` now reuses the community-scoped
accessible-channel drop instead of repeating it.
- Tests seed accessible channels through one `seed_accessible_channels`
helper instead of writing cache internals.
## Tests
- `telemetry::tests::only_plain_target_level_directives_use_targets`
checks which directive strings are plain. It covers span directives,
field directives, whitespace, empty segments, empty targets (`=debug`)
and bad levels.
- The rewritten `env_filter_tests` assert on captured log output rather
than `Display` strings or cached callsite interest, so they are stable
when run in parallel. `span_directives_keep_env_filter_semantics` proves
that `[conn]=debug` still enables events only inside the span.
-
`state::tests::postgres_tests::a_lost_open_set_invalidation_grants_a_revoked_channel_only_until_max_age`
runs two relay states on one database, with no pub/sub between them. For
each revocation (private, deleted, unlisted), it:
1. primes the reader pod;
2. revokes the channel in SQL and invalidates only the writer pod;
3. shows that a new reader is still granted the channel within the
window;
4. ages the cached set past the limit;
5. asserts that a new reader and an earlier cached reader are both
denied.
Dropping the age check fails it. Never caching the open set fails its
within-window control.
- `env_filter_tests::directive_filters_log_what_env_filter_logs` emits
events at every level for six targets, including prefix lookalikes. It
asserts that the filter built for each of 17 directive lists logs
exactly what `EnvFilter` logs for that list. Routing `buzz_relay=` to
`Targets` fails it.
- `state::tests::accessible_channels_join_member_and_open_halves` checks
the merge. The two existing scoped-invalidation tests now also assert
the open half.
- These state tests, and the two existing ones, were not in the `just
test-unit` allowlist. They are infra-free, so they are now selected by
exact name, and `scripts/run-tests.sh` mirrors that.
Identified debt, not fixed here: the per-reader member half keeps the
pre-existing unfenced read-then-insert (a raced fill only reaches that
reader, as before).
`handlers::req::tests::expiry_during_stalled_{history,search}_read_releases_permit_and_claim`
are not selected by any CI lane.

BUZZ-272: Deny workflow runs for banned owners (#8242)
## Summary A workflow whose saved owner is banned from the community can no longer create runs through any trigger: webhook, channel-event, cron, or signed command trigger. Every one of those doors already calls `WorkflowEngine::check_owner_authority`, which re-checks the owner's channel role. That gate now also reads the owner's authoritative restriction state. A ban denies the run, and a failed lookup fails closed. Unbanning restores admission. On the webhook door the denial is the same generic 404 as before, and no run is queued. On the event and cron paths, a ban denial is logged at WARN at most once per workflow every ten minutes, and at DEBUG in between. A failed lookup and every other denial still warn every time. The handler-local ban lookup in `api/bridge.rs` is removed because the shared gate covers it. This is a point-in-time check: a ban committed after the lookup can race with run creation. It does not cancel existing runs. Community timeouts do not block runs in this change. This PR also carries the shared mesh receive fix needed for independent validation (see Shared carry). ### Related BUZZ-272. - Invitations: [#8237](https://github.com/block/buzz/pull/8237). - Route coverage: [#8239](https://github.com/block/buzz/pull/8239). - Live-session revalidation: [#8241](https://github.com/block/buzz/pull/8241). - Staging runbook: [#8235](https://github.com/block/buzz/pull/8235). ### Testing Postgres lane: - `on_event_denies_run_while_owner_banned`: a banned owner's channel-event trigger creates no run, and after unban it creates one. - `cron_tick_skips_banned_owners_without_consuming_the_claim`: one tick skips a banned owner and an agent whose human owner is banned, while an unbanned workflow on the same tick still fires. After unban, a tick for the same scheduled instant fires both, so the denial did not consume their scheduled-fire claim. - `on_event_denies_run_when_restriction_lookup_fails`: the event path fails closed when the restriction read errors, and fires once the read succeeds. - `webhook_admission_enforces_owner_ban_tenant_scope_and_lookup_failure`: the HTTP door returns the same generic 404 for a wrong secret, a banned owner, a forbidden role and a failed restriction lookup, with no run created. It also covers another tenant's allowed control and unban. Unit lane: - `ban_denial_warns_once_per_interval_while_other_denials_always_warn`. Results: - At `81c367f48`, CI passed: Unit Tests 572/572, PostgreSQL Tests 1169/1169 and Relay E2E. A local-relay E2E also passed: - unbanned webhook: 202 and one run; - banned webhook: generic 404 and no run; - banned event trigger: no run; - after unban: one run. - At `72c8d8bbc` (merged with main), CI passed: Unit Tests (including all 171 buzz-workflow unit tests), PostgreSQL Tests 1227/1227 (all four ban tests listed by name), and both `Build (linux/amd64|arm64)` image jobs, which build with `--locked`. A Blox run at the same head also passed `cargo metadata --locked`, fmt and clippy, and the buzz-workflow unit tests passed there with no database reachable. - Not covered: the signed trigger has no dedicated test. It calls the same gate, which was confirmed by reading the code. ### Shared carry #8237, #8239, #8241 and #8242 each carry the same mesh-receive fix, boot and scraper regressions, and push-lease fixture correction. Whichever lands first owns them, and the others drop them on their next main merge. ### What got simpler The ban check now lives in the one gate every run-creation door already shares, so there is one fewer handler-local branch. Cron, event and signed triggers get the same protection without per-door code. The cron loop body is now `cron_tick(now)`, so a test can drive one tick without the 60-second sleep. buzz-workflow's infra-free unit tests ran in no CI lane. `just test-unit` and its cargo fallback in `scripts/run-tests.sh` now run them. buzz-review-completed 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: seiler <seiler@squareup.com> Signed-off-by: Brad Seiler <seiler@squareup.com> Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Codex <noreply@openai.com> Co-authored-by: Codex <codex@openai.com> Co-authored-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

## Summary Follow-up to #8653. The `prepare_reconnect` doc comment in `crates/buzz-acp/src/relay.rs` still said it runs `begin_reconnect` "with the real clock and RNG". `begin_reconnect` stopped taking a clock when `live_until` moved to #8688, so the comment now says "with the real RNG".

fix(relay): close a REQ whose history read failed instead of sending EOSE (#8692)
## Summary **Merge order:** this lands and deploys **before** [#8688](https://github.com/block/buzz/pull/8688). That PR's buzz-acp resume cursor counts on a failed history read never ending in EOSE. Until #8688 ships, buzz-acp re-sends a REQ as soon as it gets an error CLOSED. The relay's REQ rate limit bounds that loop, and buzz-acp already parks on a rate-limited CLOSED. #8688 replaces this with a per-subscription backoff. When a historical query fails for a reason other than a statement timeout, the relay logs the error and still sends `EOSE`. EOSE means "you have every stored event" (`ARCHITECTURE.md` §5, NIP-01). A client that resumes from its last-seen point therefore treats the failed read as complete, advances past it, and never replays that history. This is RPR #1: a failure must not become an authoritative empty result. The history task now returns the CLOSED reason to send: - **Statement timeout:** `["CLOSED", sub_id, "error: query timed out"]`, unchanged. - **Any other DB error:** `["CLOSED", sub_id, "error: database error"]`. - **Cleanup:** CLOSED goes through the existing `close_if_owner` path, so the subscription, its sub-registry filters and its topic refcount are released, the same as on a timeout. - **Docs:** `ARCHITECTURE.md` §5 now states this contract. **Clients don't hot-loop on it.** Checked at `main` |

db: warm the relay read pool toward its ceiling at boot (#8651)
## Summary At boot the relay's read pool holds only its floor (`max/5`). A freshly started pod that meets a reconnect burst, such as the clients a rolling deploy just moved off an old pod, has to dial the rest of its reader connections inside the 150ms reader acquire budget. Cold dials (TCP + TLS + SCRAM) overrun that budget under load, so those reads fall back to the writer (`reader_acquire_timeout`). This PR warms the read pool toward its ceiling in the background, right after the existing boot ping succeeds: - **Off the startup path.** It runs in the boot-ping task that was already spawned and not awaited. Startup and readiness are unchanged. - **Bounded.** One pass, in waves of at most 5 concurrent dials. Each acquire, dial included, is bounded by the pool's own 150ms acquire timeout. A dial slower than that is dropped and counts as failed, just as it would on the request path. A wave that opens nothing ends the pass, and the pass runs at most twice the waves a clean pass needs. There is no sleep, backoff or second pass. - **Released idle, then reaped.** Warmed connections are dropped back into the pool, not closed. sqlx's existing `idle_timeout` reaps them back down to the floor, so there is no new reaping logic. - **Skipped if the reader is down.** If the boot ping finds the reader unreachable, the warm pass doesn't run. Today's all-writer warning is the only signal in that case. - **No alert noise.** Warm acquires use plain `acquire()`, not the instrumented reader acquire, so warm misses don't count toward the `buzz_db_reader_*` acquire-timeout metrics that fallback alerts watch. The existing `buzz_db_read_pool_*` gauges show the result. - **Logged.** The outcome is logged at info when the pool reaches its ceiling, and at warn when it falls short. Both lines carry `ceiling`, `held`, `failed` and `elapsed_ms`. The ceiling field isn't named `target`, because the relay's JSON formatter already emits the event target under that key. `held` counts the connections the pass dialed plus any idle floor connections it reused. - **Window.** Until the pass ends it holds every reader connection, the floor included. That is usually before the pod takes traffic. Boot-probe retries can delay the pass past the listener bind, though, so it can briefly overlap traffic, and a routed read that misses in that window falls back to the writer. **Cost.** Each pod holds up to `max_connections` reader connections, instead of the floor, for about `idle_timeout` after boot. Operators should size the reader's `max_connections` for pods × `BUZZ_DB_READ_POOL_SIZE` (falling back to `BUZZ_DB_POOL_SIZE`), counting the old and new pods that overlap during a rolling deploy. The configuration already permits that, and the `reader_min_connections` doc now gives the same advice. Booting pods can have up to the floor plus 5 dials in flight, because sqlx's floor maintenance dials alongside the first warm wave. **Simpler?** This adds one bounded helper and leaves the pool configuration alone: no new knob and no new metric. Separately, I identified some debt: a REQ with `limit: 0` still acquires a reader to run an empty query. A short-circuit straight to EOSE would remove that acquire, and a companion desktop change sends `limit: 0` live REQs. ### Related issue N/A. This is part of a set of reconnect-load reductions. The companion client changes (resume cursor, reconnect spreading) are in separate PRs. ### Testing - `cargo fmt --all -- --check`, plus `cargo clippy -p buzz-db -p buzz-relay --all-targets -- -D warnings`. - `cargo test -p buzz-db`, including 6 new `reader_warm_tests`: - a table test for wave sizing - an exact target - the bound when dials keep missing - a top-up after a partial wave - a dead reader ending the pass after one wave - an unreachable reader skipping the warm - The new Postgres test `reader_pool_postgres_tests::reader_boot_ping_warms_pool_to_max_in_background`: after `spawn_read_pool_boot_ping()`, the pool settles at size = idle = max. It runs through `scripts/postgres-test-run.sh` together with the existing reader-pool Postgres tests, and `scripts/test-postgres-test-discovery.sh` passes. - The new Postgres test `reader_pool_postgres_tests::reader_warm_at_production_budget_ends_partial_when_dials_stall`. It builds the pool with the production constructor, so it has the real 150ms budget, and puts it behind a proxy that relays 3 dials and stalls the rest mid-handshake. The pass must end with 3 held and 7 failed after exactly 10 dials, finish in under 2s, and not dial again afterward. - Mutation checks. Each of these failed a new test: - zero waves - targeting the floor instead of the ceiling - `close_on_drop` instead of releasing - no early abort - no wave bound - no top-up - no ping gate - no concurrency cap buzz-review-completed 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

db: answer match-nothing event reads without taking a connection (#8663)
## Summary A NIP-01 `limit: 0` REQ asks for no stored events: it is a live-only subscription. The relay still acquired a pool connection for it, then ran a `LIMIT 0` query. Desktop is moving live subscriptions to `limit: 0`, so these acquires add up during a reconnect burst. The existing match-nothing shortcuts in `query_events_on` (an empty `kinds`, `authors`, `ids` or `#e` list) had the same cost, because they ran after the caller had already acquired a connection. This PR moves the query validation and the match-nothing checks into one function, `answer_without_db`. It adds a zero page (`limit: 0`, after the page clamp) to those checks, and every entry point now calls the function before it acquires a connection: - `query_events_with_operation`, which covers `Db::query_events` and its writer variants - `Db::query_events_routed` - `Db::query_events_routed_bounded` - `query_events_on`, for the session (aux) path that already holds a connection Invalid queries still return the same errors, in the same order, and match-nothing queries still return an empty page. What changes besides the connection: - A routed match-nothing read now returns before `route_read`, so it emits no `buzz_db_route_decision` and runs no replica proof. As desktop moves live subscriptions to `limit: 0`, writer/replica route-decision ratios will shift. Fewer reads are routed; no read changes destination. - During a pool outage, an invalid query now returns its `InvalidData` error instead of the pool error. - A zero page skips checks that only SQL applies, such as rejecting a negative `offset`. Current callers only build non-negative offsets. **Simpler?** Yes. The four separate early returns become one predicate, and the page-limit clamp is computed in one place (`page_limit`), shared by the shortcut and the SQL builder. ### Related issue N/A. This is a follow-up from https://github.com/block/buzz/pull/8651. ### Testing - New unit test, `runtime::postgres_tests::match_nothing_reads_take_no_connection`. Both pools point at a closed port, replica routing is on, and the fence is forced open, so a routed read that reached `route_read` would try the reader first. Each match-nothing shape (`limit: 0`, `max_limit: 0`, and an empty `kinds`, `authors`, `ids` or `#e` list) must return an empty page through the writer, routed and routed-bounded entry points. Invalid queries that would also match nothing must return `InvalidData` through each entry point. None of these may record a `buzz_db_pool_acquire_attempts_total`. A `limit: 1` routed control must fail after trying both the reader and the writer. The test runs in the `cargo nextest run -p buzz-db --lib` unit lane. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

fix(buzz-acp): spread 1012 reconnects and keep replay gaps across a dropped socket (#8653)
## Summary During a relay rolling deploy, every agent harness connection gets a close 1012. `buzz-acp` reconnected immediately, so a pod's agents all arrived at once, and `jittered_duration` produced 0.80–0.89× rather than the intended ±20%. Separately, a replay that was cut off by a dropped socket could lose the gap it was replaying. This PR makes three changes: 1. **Reconnect spreading.** The Close frame's code is now read. After 1012 (Service Restart) or 1001 (Going Away), the first reconnect attempt waits a uniform random delay in [0, 10s], which matches the relay's server-side drain spread. Other closes keep the immediate first attempt. Both reconnect entry points go through one `prepare_reconnect`. 2. **Gaps survive a dropped replay.** A recorded dropped-event gap (`channel_dropped_since` / `membership_dropped_since`) is retired when the replay REQ is written, as before. On `main` it is then gone: if the socket drops before that replay finishes, the next `since` comes from `last_seen`. Relay history is sent newest first, so `last_seen` can already be past the gap, and the lost event is skipped. Now the retired record is kept per connection until that subscription reaches a counted EOSE. If the connection ends first, the record is restored (merged by `min` with any newer loss), so the next replay still starts at or before the gap. - This covers overflow-recovery and reconnect replays, and a socket that dies partway through a resubscribe (`RetryConnection`): every fresh-connection resubscribe closes out the previous socket first. - **Ambiguous EOSE is ignored:** EOSE carries only the subscription ID. If a REQ for the same ID is written a second time on one socket (an overflow-recovery replay, or an unsubscribe followed by a re-subscribe), that subscription's EOSE never releases its retired gap for the rest of that socket. - **Cost:** a gap whose replay EOSE can't be counted (a superseded REQ) is restored at close, so the next reconnect replays once more from it. State is one oldest gap per subscription, cleared on unsubscribe, and the first unambiguous EOSE for that subscription retires it. Until the relay sends CLOSED for a failed history read (#8692) and that relay is deployed, an EOSE sent after a failed read also retires the gap, even though nothing was replayed. That's no worse than `main`, which drops the gap as soon as the REQ is written. - **Removal paths:** unsubscribe clears the retired gap; the per-socket REQ tracking is cleared only when the connection closes. 3. **Jitter fix.** `jittered_duration` is now a symmetric ±20%, sampled from the OS CSPRNG. The replay cursor itself is unchanged: `channel_since` and the new `membership_since` share one pure `resume_since`, which is `main`'s `min(last_seen, dropped)`, else the baseline. **Moved out of this PR:** an earlier revision also resumed quiet subscriptions from an EOSE-derived `live_until`. The relay currently sends EOSE when a history read fails, so `live_until` could certify coverage that was never delivered. That term moves to #8688, alongside its `buzz-acp` backoff on that CLOSED. #8688 merges after the relay sends CLOSED for a failed history read (#8692) and that relay is deployed. **What got simpler:** `channel_since` and `membership_since` share `resume_since`, which replaces six inline copies of the membership `since` computation. `SubscribeMembership` now honours a recorded membership gap like every other membership REQ. **Identified debt (not changed here):** - Quiet channels and the membership subscription still replay from the process-start watermark on every reconnect, so a long-running agent pays more for each bounce. #8688 addresses this. - A non-rate-limited, non-auth CLOSED re-REQs the channel immediately, bounded only by the relay's rate limit (#8688). - `try_autonomous_reconnect` restarts at attempt 0, so a relay that accepts and immediately closes with a non-1012 code sees an immediate retry each time. - Per-REQ wire IDs would make every EOSE unambiguous. They'd remove the supersede tracking and let an overflow-recovery replay's EOSE release its gap. Today a superseded replay keeps the gap until close, and on a busy channel past the relay's 1000-event page limit that can repeat a bounded replay on every reconnect. The remaining per-connection sets would then collapse into one record. Proposed as a follow-up. ### Related issue N/A. This is part of a set of reconnect-load reductions. Companion PRs: desktop (#8652), mobile (#8659), relay read-pool warm (#8651), `buzz-acp` CLOSED backoff (#8688) and relay CLOSED on a failed history read (#8692). ### Testing - On a Linux workstation, at the head SHA: - `cargo fmt --all -- --check` and `cargo clippy -p buzz-acp --all-targets -- -D warnings` pass. - `cargo test -p buzz-acp -- --test-threads=1`, with the harness env cleared per `crates/buzz-acp/TESTING.md`: - lib: 1078 passed, 3 ignored, both serial and with default parallelism. - `pool_lifecycle_state` (9), `run_task` (9) and `stdio_contract` (1) all pass. - `git_bootstrap`: 2 of 4 fail with `could not read Username for 'https://relay.invalid/...'`. The same two fail identically at the merge base `b310fea0` on the same workstation, so they're environmental. - `cargo test -p buzz-acp --lib relay::resume_tests` with default parallelism: 10 runs in a row, 18/18 each time. - New `relay/resume_tests.rs`: - table tests for `resume_since`, `first_reconnect_delay` and the jitter math - Close-code capture, and the close code consumed by the next reconnect - a counting fake relay showing 1012/1001 delay the first connect while 1000/1006 don't - unfinished gap replays (channel and membership) keep their floor across repeated drops, with a newer event before or during the replay; a completed replay releases it - delayed EOSE of a superseded REQ (channel and membership overflow recovery), with `last_seen` past the gap - a redial after a failed resubscribe, a new loss during an unfinished replay (channel and membership, merged by `min`; a repeated close is a no-op), a second REQ on one socket retiring an older loss (the older one is restored), `wait_for_reconnect` restoring a retired gap, and unsubscribe clearing it - a connected `SubscribeMembership` asserting its wire `since` - 19 mutations of `relay.rs`, applied one at a time, each fail at least one `relay::` test: drop the loss restore on close, take `max` instead of `min` when merging a restored loss (channel or membership) or when a second REQ stashes one, keep the retired gap on EOSE, release it on a superseded EOSE, drop supersede tracking, drop the redial restore, keep the retired gap on unsubscribe, inline the membership `since`, skip `note_req_sent` (channel or membership), skip `prepare_reconnect` (either entry point), do not consume or record the close code, do not delay 1001, revert the jitter band, and let `last_seen` beat the gap. - Exercised against a real relay (Postgres 16, Redis) at an earlier revision whose reconnect-delay code is identical to this head (`prepare_reconnect` and `first_reconnect_delay` unchanged), comparing the merge base with that head: | | Base | Head | |---|---:|---:| | 20 agents after a 1012: reconnect min / median / max | 1 / 2 / 3 ms | 622 / 3,638 / 9,233 ms | | Reconnects per one-second bucket, 0–10s | `20,0,0,0,0,0,0,0,0,0,0` | `4,2,2,3,2,1,2,2,1,1,0` | | Mention sent during the bounce, answered | once | once | - The new tests run in CI via `just test-unit` (`cargo nextest run -p buzz-acp`). buzz-review-completed 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Sonnet 5.5 <noreply@anthropic.com> |

Add a scenario-driven relay load generator (#8636)
## Summary Buzz has no way to load-test the relay as a whole. `wamp_bench` sends kind:9 messages from one identity to one channel, and `perf/relay_bus_scaling.py` only measures Redis fan-out. Neither can show what happens to a relay with many more users, channels, or deep threads. This PR adds `buzz-loadgen`, a load generator in `crates/buzz-test-client`: - `buzz-loadgen seed <scenario.toml>` creates communities (through `POST /operator/communities`), channels, channel history, and deep threads. - `buzz-loadgen run <scenario.toml>` drives simulated humans and agents through ramp steps (1x, 2x, ...) and prints p50/p90/p99 latency, errors, and rate-limit rejections per operation for each step. - Humans hold a WebSocket with live subscriptions, fetch history on connect, and send presence, typing, messages, thread replies, and reactions. Agents authenticate with a NIP-OA tag, poll HTTP `/query`, post through HTTP `/events`, and send encrypted observer frames to their owner. - Per-client rates come from the scenario. Set them to model a deployment, and a step of `users = 10` means 10x that deployment's population. - Every identity, host, and channel id comes from the scenario's `run_id`, so `--shard i/n` splits a population across machines with no coordination. - Each step measures from ramp start to hold end, so connect failures during the ramp count. A step aborts the run when an operation's error rate or p99 (delivery included) crosses the scenario's `[abort]` limits, when a relay `CLOSED`s a live subscription often enough, or when a client exits unexpectedly. The report names the limit that tripped. - Each connect plus authentication has a deadline (`target.connect_timeout_secs`), and shutdown is bounded, so a relay that stalls connections still produces a report and a non-zero exit. - `seed` exits non-zero unless the relay accepted every planned post. - `NostrWsConnection::connect_to_addr` opens the TCP connection to a given address while the URL still names the host. This lets a client inside the relay's cluster reach a community host through the relay's service address. - `wamp_bench` is deleted. Its paced single-channel load is a subset of a scenario. What got simpler: one load tool instead of two partial ones. The change touches only test tooling, the unit-test lane, and one additive method in `buzz-ws-client`. Relay code is unchanged. ### Related issue None found. ### Testing Smoke run on a Linux workstation against a local relay built from this branch, with its own Postgres, Redis, and MinIO containers: ```bash cargo run --release -p buzz-test-client --bin buzz-loadgen -- seed perf/scenarios/local-smoke.toml cargo run --release -p buzz-test-client --bin buzz-loadgen -- run perf/scenarios/local-smoke.toml ``` - `seed`: 710 of 710 posts accepted (10 channels, 200 history messages, 10 thread roots, 500 thread replies). - `run`: both steps (1x = 50 humans + 5 agents, then 2x) completed with 0 errors and 0 rate-limit rejections. Every operation recorded traffic: 55/55 connect/auth, 205/205 live subscriptions, 150 history fetches, presence/typing/observer frames, messages and reactions, HTTP `/query`, HTTP `/events`, and publish→delivery. Delivery p99 was 45 ms at 1x and 42 ms at 2x. - Failure paths are covered by unit tests: a listener that accepts TCP but never answers (connect deadline, then `run` aborts and returns), a fake `/events` server that rejects posts (`seed` fails), `CLOSED` subscriptions, and invalid scenarios. `just test-unit` (and its `scripts/run-tests.sh` fallback) now runs the new `loadgen::` unit tests. Before this change, no CI lane ran `buzz-test-client` lib tests. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

Add standalone owned-community deletion handlers (#8645)
## Summary
User deletion needs to delegate owned communities to the existing
community deletion process and report what is still waiting. This adds
the standalone components for that flow; wiring them into the user
workflow is a later change.
The owned-community handler checks for an existing community deletion
request first. If none exists, it calls `submit_and_prepare`, the same
function used by the community CLI. The handler saves the child request
ID, last observed status, and operator instructions on the existing user
stage. Community approval and execution remain separate. Repeated or
concurrent calls reuse the existing child without resetting its approval
or execution state. The user stage follows the current request for its
approved community ID. If an operator aborts A and submits B for that
community, the next invocation saves B on the same stage row.
An unfinished child leaves the user stage waiting. A later handler
invocation refreshes its observation and completes the stage when the
child reaches logical completion (`retention_pending` with a completion
timestamp). Retained-copy obligations remain visible in the saved
result. Lease owner and generation checks protect stage updates.
The separate summary handler reads only the user request, approval, and
stage tables. It lists unfinished stages, saved external waits and
operator actions, completed results, and inventory communities not yet
reached. It never queries or refreshes community deletion state, so
child statuses are explicitly labeled as last observed.
### Scope and rollout
- No migrations, new HTTP endpoints, CLI commands, or worker dispatch
changes. Owned-community intake remains disabled.
- Waiting uses the existing stage status plus `metadata_json.waiting`.
This slice does not advance past waiting stages. Integration must add an
explicit resume or bounded revisit cadence before enabling automatic
scheduling.
- The CLI and user handler share the existing database submission,
inventory building, and inventory freezing operations. There is no API
wrapper class or second insertion path. Preparation failures leave a
durable child request and a retry record on the user stage; subsequent
lookup exposes instructions for the operator to finish preparation.
Guidance distinguishes operator-origin preparation, automatic
owner-origin preparation, blocked requests that need remediation and
`unblock`, and aborted requests that can be replaced.
- Existing submission accepts a host for the CLI or an immutable
community ID for the parent. A transaction protects target resolution
and admission. ID-pinned calls never replace an existing child, even an
aborted one. Inventory helpers take their store and media dependencies
directly. Successful stage persistence clears any saved waiting marker.
- These components become available to callers after release but are not
scheduled by the relay or user worker. No data migration is needed to
roll back this change.

fix(push-gateway): log which App Attest certificate check failed (#8671)
[#8630](https://github.com/block/buzz/pull/8630) made App Attest rejections log which check failed. In production, an internal iPhone's fresh enrollments now log `reason: certificate` with `detail: invalid certificate path or structure`. That detail still covers about eight distinct failures: a non-array or empty `x5c`, a bad configured root, a malformed or duplicate-extension certificate, any webpki path rejection (untrusted issuer, expiry, unsupported critical extension and so on), and a key-usage mismatch. So the logs still cannot say why this device's attestation is rejected while other devices enroll normally. Each certificate failure now carries a `CertificateCheck`, and the existing warning's `detail` names it: - `x5c is not a non-empty array` - `invalid configured root` - `invalid encoding at x5c[i]` - `invalid key usage at x5c[i]` - `path rejected: <webpki error>`, for example `CertExpired { time: .., not_after: .. }` or `UnknownIssuer` The webpki error includes only its variant and, for validity errors, the timestamps it compared. It includes no certificate bytes or device identifiers. The `reason` stays `certificate`, and the HTTP response stays a uniform `invalid_attestation`. ### Validation - Added tests: a table test runs each signed bad-chain case through the production `verify_chain` and asserts the exact check: wrong usage, expired, unknown critical extension, duplicate extension, trailing bytes, empty chain, and a bad root. Swapping the key-usage result for another check fails it. The shared certificate constraint corpus now builds its chains from the same case list. - The full push gateway suite passes locally. Clippy is clean. The local pre-push `rust-tests` lane failed only in `buzz-relay` tests, which do not depend on this crate, so I skipped it for the push and am relying on CI for it. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Tom Brow <tomb@block.xyz> |

perf(db,relay): bound thread participant scans and coalesce live summaries (#8635)
## Summary A thread summary's `participants` (up to 10 recent authors, used for the facepile) was computed by aggregating **every** reply in the thread. The live `kind:39005` emit runs that aggregate on the writer after every reply insert and every threaded delete. Each summary therefore cost O(thread), recomputed after every reply, so one very large thread could saturate the writer. ### Scale and impact A single long-running thread can grow to hundreds of thousands of replies and take several new replies per second. Each of those replies then pays a whole-thread aggregate on the writer, so writer CPU follows the reply rate of the largest active threads, and the read-side participant queries (channel window, thread root summaries) slow down the same way. Synthetic reproduction (PostgreSQL 17, the repo's `schema/schema.sql`, default `shared_buffers`): one channel with 200k background messages and three threads of 450k, 6k and 300 replies from a few authors with ~800-byte bodies. `EXPLAIN (ANALYZE, BUFFERS)` of the participant query, warm cache (runs 2–3 of 3): | Thread | Before (whole-thread aggregate) | After (newest 1000 replies) | |---|---|---| | 450k replies | ~7.6 s, ~117k buffers read, ~16k temp blocks spilled | ~6.8 ms, ~4k buffers | | 6k replies | ~25 ms, ~24k buffers | ~7 ms, ~4k buffers | | 300 replies | ~2.6 ms, ~1.2k buffers | ~2.6 ms, ~1.2k buffers | Cost now stops growing at 1000 replies, and small threads cost the same as before. With coalescing, a busy thread runs this query at most about once per second per pod instead of once per reply. ### Change 1. **Bound the participant scan to the newest 1000 replies.** All three participant readers now share one SQL fragment (`recent_thread_participants_sql!`): - `get_thread_summary` (the live 39005 emit) - the channel-window batch - `resolve_thread_root_summaries` The fragment walks `idx_thread_metadata_window` newest-first with `LIMIT 1000`, then joins `events` only for those rows, to get `pubkey` and drop deleted replies. Deleted replies keep their `thread_metadata` row, so they count toward the 1000 but contribute no author. It aggregates by author and returns the 10 most recently active. Cost no longer grows with thread size. Desktop and mobile show the 3 most recent participants and the forum view shows up to 10, so an author who hasn't posted in the last 1000 replies is not visible in any client today. `NIP-CW`, `docs/bridge-channel-window.md` and the `ThreadSummary::participants` doc now state the bound, deleted replies included. 2. **Coalesce live summary emits per thread root.** `emit_live_thread_summary` goes through a new `CoalescedRefresh` keyed by `(community, root)`: - A quiet thread emits immediately, as before. - On a busy thread, emits are spaced at least 1s apart per pod. A trailing emit covers the rest of the burst and reads state committed after its last mutation. - Because emits are at least 1s apart, consecutive overlays from one pod always get strictly increasing `created_at`, so the client's newest-wins replacement is never tied. - A panicking or cancelled refresh releases its key, including a task dropped before its first poll: the release guard is built before the spawn. Each run is bounded by a 30s timeout so a hung refresh can't wedge it. ### What got simpler - Three hand-written copies of the participant aggregate are now one fragment. - `get_thread_summary` is one statement instead of two round trips. - The channel-window batch dropped its `ROW_NUMBER()` window function and the `GROUP BY root, pubkey` over every reply of every root on the page. ### Related issue None found. ### Testing - `participant_summaries_read_only_the_newest_replies` (buzz-db, Postgres) seeds a thread with 1001 replies: - an early author, pushed just outside the window - a filler author - a deleted reply - a latest author All three readers must return `[latest, filler]`. Mutant check: removing the `LIMIT` (whole-thread aggregate) turns it red. - `coalesced_refresh` unit tests (paused tokio clock): - A 100-request burst runs once immediately and once trailing, then frees the key. - Separate keys run independently. - A panicking refresh doesn't wedge its key. - A hung refresh times out and releases its key. Mutant check: removing the timeout turns it red. - A request that arrives while a run is in flight gets one trailing run, and that run reads the state written mid-run. Mutant check: dropping the rerun flag turns it red. - A task dropped before its first poll (runtime shut down) still releases its key. Mutant check: building the guard inside the task turns it red. These run in `just test-unit` (added to the buzz-relay `--lib` filter and `scripts/run-tests.sh`). - Blox gate: `cargo fmt --check`, clippy `-D warnings` (buzz-db, buzz-relay), and the full buzz-db and buzz-relay Postgres nextest lanes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

BUZZ-413: Add user deletion fence storage (#8632)
## Summary Add storage and lock helpers for the first user-deletion fencing PR. No serving handler or deletion worker calls these helpers yet, so this does not block users or enable real deletion. The operator-global `user_deletion_fences` table stores global user restrictions and community-scoped agent restrictions. Community and profile deletion retain these rows unchanged. `scope_community_id` records a restriction's scope; it does not make the row community-owned. The helpers use the caller's transaction, stable identity lock keys, ordered shared/exclusive locks, and indexed lookups. Inserts preserve the original request and owner on retry and reject conflicting provenance. Inserts validate the current worker lease and approved inventory through the existing entity-deletion guards. Callers must still verify that the target identities and agent ownership belong to the request. This is an additive schema expansion with a five-second migration lock timeout. It adds no database triggers, functions, foreign keys, or backfills. Both schema sources and operator-global registrations are updated. The unused request-ID index was removed. The existing community-deletion catalog and purge logic are unchanged. Tests cover live schema parity, concurrency, rollback, and retention through the existing purge and verification functions. ### Related issue Part of [BUZZ-413](https://linear.app/squareup/issue/BUZZ-413/gate-user-and-owned-agent-activity). This is the storage foundation; serving checks and real workflow handlers follow separately. No duplicate fence-storage PR found. ### Testing No manual app testing: these utilities have no application callers yet. Local PostgreSQL validation uses an isolated test container and the repository's per-test database runner. Passed 84 selected PostgreSQL tests covering fence authorization, concurrent inserts, schema parity, retention, community deletion, entity-deletion storage, and user discovery. The authorization regression also failed as expected when the insertion guard was temporarily removed; the guard was restored before the final run. Command: `scripts/postgres-test-run.sh -p buzz-db --lib -E 'test(/user_deletion_fences/) | test(/admin_schema_parity_between/) | test(/^store::deletion::postgres_tests::/) | test(/^store::entity_deletion::postgres_tests::/) | test(/^store::user_deletion::/)'` with the local test PostgreSQL connection and `PG_BIN_DIR` configured. The full `just test` run had one failure: `composition_tests::composition_log_does_not_leak_issuer_url` missed an expected log message. The same compiled test passed when rerun alone. No relay logging code is changed by this PR. The full local `just ci` run and all normal pre-push hooks passed on the updated branch.

Stop requiring the 0032 roster trigger at relay startup (#8611)
🤖 ## Summary When a relay starts, it checks that a database trigger from migration 0032 is installed and works. If the trigger is missing, the relay refuses to start. This PR removes that startup check, so a later migration can drop the trigger. The trigger blocks a stale channel member list from being saved. Since #8316, the relay runs the same check in Rust before every save of a member list. The trigger is now only a duplicate backstop. Removing it lets #8494 compute the `member`/`bot` label when it reads members, instead of storing `bot` in the database. This PR does not drop the trigger. The trigger stays installed and keeps working. Only the requirement that it exists at startup is removed. ### Related issue Prepares the trigger retirement that #8494 needs (review thread on #8494 about storing `bot`). No duplicate PRs found. ### Rollout `docs/database.md` requires this sequence for retiring a trigger: 1. Ship the replacement in the app. This was #8316. 2. Fully deploy a release in which no relay requires the trigger. **This PR.** 3. Drop the trigger in a separate migration, and name the step-2 release as a required stop in its release notes. A relay from before this PR refuses to start after the trigger is dropped. So every environment, staging included, must run this release before the drop ships. ## Details - Removed the startup step `channel_roster_fence`, which ran the catalog check and a behavior probe (a test insert that must be rejected, then rolled back). - Removed the catalog check that ran after migrations in `run_migrations_locked`. - The catalog check function stays, but only tests use it. - Removed four tests about the startup gate. Added `migrations_run_without_the_roster_trigger`: it drops the trigger in a scratch database and runs the migrations. If the post-migration check comes back, the test fails. - `observability_source` lists the event writers that may skip the guard.

fix(relay): store a kind:9000 and its membership writes in one transaction (#8606)
Follow-up to #8575. ## Problem Today a kind:9000 is stored first and the membership write runs afterwards, on its own. If that write fails, the relay logs it and still returns an accepted OK. A resend of the same event then returns `duplicate:`, so the person is never added. This is the catch-log-and-accept failure that Review-Proven Rules #1 and #5 describe. ## Change kind:9000 now uses the same atomic path as kind:9002 (`persisted_atomically` in ingest). - **`buzz-db`:** new `put_members_with_event`, which runs one transaction: 1. Take the channel's membership lock, before the event insert, the TTL lock and the channel row. This matches the order the other membership writers use, so it adds no new lock cycle. 2. Store the event. If it's already stored, roll back and return `Duplicate`. 3. Run the existing `put_members` decisions and upsert. These now live in a shared `put_members_on` step on the transaction. 4. Commit. - **Failure:** nothing is stored and the client gets an `error:` rejection, so it can resend the same event and have it applied. - **Everyone refused:** if the decisions under the lock refuse every person, nothing is stored and the event is rejected with the same text validation gives. Before, a single-person add refused at that point was accepted with an empty message. - **After commit:** the live effects stay as they were. They're best-effort and read the committed state: cache invalidation, `member_joined` notices, member-added notifications and 39002 discovery. - **`NOSTR.md`:** now says a failed kind:9000 can be resent as is. ## What got simpler - kind:9000 no longer has its own store-then-apply path in ingest. It shares the atomic branch with 9002 and workflow deletion. - `apply_put_user`'s "write failed, report it as a per-person rejection inside an accepted OK" branch is gone. - The `Db::put_members` wrapper is deleted. Its only caller was the kind:9000 path. ## Identified debt (not in this PR) kind:9001 (remove), 9021 (join) and 9022 (leave) have the same gap. Each stores the event, then runs the membership write in `handle_side_effects`, and a failure is only logged. kind:9008 and 9005 follow the same store-then-apply pattern. These can move onto the same atomic shape in a follow-up. ## Tests - `failed_put_user_stores_nothing` (relay, Postgres): a test trigger fails the second person's row in a two-person add, after the event row and the first person were already written in the same transaction. It checks: - Both the send and a resend are rejected with `error:`. - No kind:9000 is stored, nobody is added, and no `member_joined` notice is posted. - With the trigger dropped, the same signed event adds both people. - One more resend returns `duplicate:` and posts no second notice. - `put_members_with_event_stores_the_event_with_its_writes` (buzz-db): checks the three outcomes: - Refused: nothing is stored. - Applied: the event is stored and the person is written. - Duplicate: the roster is left alone. - `put_user_refused_under_the_lock_stores_nothing` (relay, Postgres): a test trigger removes the sender from a private channel inside the write transaction, so validation passes and the decision under the lock refuses. For a single add and a batch, it checks the `invalid:` rejection, that nothing is stored and no notice is posted, and that the same event applies once the trigger is gone. - Mutation checks, run in Blox gates: - At `d18e88fd`: committing the refused event fails the buzz-db test; applying a duplicate fails the first two tests; storing the event in its own transaction fails the first two tests. - At `3b106623`: turning the refusal under the lock into `error:` fails the new refusal test, and so does committing the refused event. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

feat(relay): log who and why for NIP-FI shadow would-deny (#8634)
In shadow mode, the relay's `nip-fi shadow would-deny` line now says which client enforce would refuse and why, not just the coarse public outcome. - The line moves from `debug` to `info`. Admits still write no line. - It gains `reason`, one value from a fixed snake_case set naming the step's private condition: `community_unresolved` (community resolution failed or was unavailable), `community_stale`, `session_deadline`, `duplicate_authorization`, `missing_proof`, `invalid_proof`, `missing_assertion`, `malformed_assertion`, `verifier_unavailable`, the verifier's own error code without its `nip_fi_` prefix (for example `expired`, `unknown_issuer`, `invalid_signature_or_claims`, `token_type_rejected`), `key_mismatch`, `no_asserted_key`, `deny_set`, `owner_banned`, `not_stored_owner`, `owner_ban_unavailable`, `owner_link_unavailable` and `tenant_unavailable`. - It gains `pubkey`, the hex Nostr key of the would-be-refused client, or `absent`. On HTTP it is the verified NIP-98 proof key, for every step including community and cardinality. On WebSocket and audio it is the key NIP-42 AUTH proved, or for deny-set and deadline the key a verified token asserts. A router-guard or upgrade would-deny precedes any proof, so its line names the key the client later proves: the request's verified NIP-98 key, or the connection's first verified NIP-42 AUTH key. Each such line is written exactly once. On HTTP it is written when the handler verifies its NIP-98 proof, or as `absent` when the request ends without one. On WebSocket and audio it is written at the first verified NIP-42 AUTH, while the connection stays open, or as `absent` when an unproven connection's read loop ends (close or auth timeout), before any cleanup that can block. Its counter still increments at once. An unsigned `X-Pubkey` never counts. - `buzz_nip_fi_shadow_total` keeps exactly its `route`, `stage`, `outcome` and `community` labels, so cardinality stays bounded. No token, assertion, issuer, subject or other claim reaches the line; verifier reasons are static strings. The denial classes and response bodies clients see are unchanged. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> |

test(relay): give group-state Postgres tests a normal acquire timeout (#8564)
🤖 ## Summary The relay's PostgreSQL CI job sometimes fails in the channel group-state tests with `ensure community: Sqlx(PoolTimedOut)`. The tests themselves are fine. They connect to the test database through a test helper that waits only 100 ms for a connection, and on a busy CI runner the first connection can take longer than that. One example is `group_state_events_carry_type_then_creator` in [this #8522 run](https://github.com/block/buzz/actions/runs/40013074144/job/120623293420): it failed after 0.57 s, while its other 1110 tests passed. This PR gives these tests a pool with sqlx's normal acquire timeout. No product code changes. ## Details - `test_state_with_database_url` keeps its 100 ms timeout on purpose. Its other callers point at a closed port (`127.0.0.1:1`) to test fail-closed paths, and the short timeout makes them fail fast. - `group_state_postgres_tests::state()` is the only caller that passes it the real test database. It now builds a normal lazy pool and passes it to `test_state_with_database_pool`. The same `state()` also serves `create_with_members_postgres_tests`, `edit_metadata_postgres_tests`, and `system_channel_postgres_tests`. ### Related issue N/A. I searched open PRs for `PoolTimedOut` and `acquire_timeout` and found none for this. ### Testing To reproduce a slow first connection, I ran the tests through a local TCP proxy that waits 250 ms before it connects to Postgres: - Before this change: `group_state_postgres_tests` had 13 of 14 tests fail with `PoolTimedOut`. - After this change: all 14 pass. `create_with_members_postgres_tests` (3), `edit_metadata_postgres_tests` (7), and `system_channel_postgres_tests` (9) also pass through the same proxy. - Without the proxy, all 14 pass before and after. - `cargo clippy -p buzz-relay --all-targets -D warnings` and `just test-unit` pass. --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Co-authored-by: Larry <627498bd4bd1f281a16431e3c6cce3b5c25b6692798c78672298aefbf2f8f8b5@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

fix(push-gateway): log which App Attest check rejected a device (#8630)
When the push gateway rejected a device's App Attest attestation or assertion, it logged the reason only at debug level. In production that left a bare `401 invalid_attestation` in the access logs, with no sign of which check failed. We hit this diagnosing an internal iPhone that never received push. Its enrollments failed with repeated `401`s, and the gateway logs could not say why. Rejections now log at warn level with: - `operation`: `attestation` or `assertion` - `reason`: the existing category, for example `certificate` or `identity` - `detail`: the specific failed check, for example `invalid AAGUID` or `invalid App ID` Malformed base64 now has its own `encoding` reason. The size, base64 and challenge checks that run before full verification now take the same path. Previously they rejected without logging anything. Without `RUST_LOG`, the gateway now defaults to `error,buzz_push_gateway=warn`, which keeps every target's errors plus the gateway's own warnings. Previously the default showed only errors, and the Helm chart sets no `RUST_LOG`, so a default deployment would have dropped these warnings. The HTTP response is unchanged and stays a uniform `invalid_attestation`. The logged fields are fixed strings, with no device or request data. Companion iOS PR [#8629](https://github.com/block/buzz/pull/8629) stops a device from replaying the same rejected enrollment indefinitely. ### Validation - Added tests: a single-test binary checks the emitted JSON warning (level, operation, reason, detail) through `AppAttestVerifier::verify_attestation`, for malformed base64, an empty proof, and malformed CBOR. Another checks that the default filter keeps gateway warnings and dependency errors, drops dependency warnings, and still honors an explicit `RUST_LOG`. Both fail when the warning is downgraded to debug or the default filter loses its `error` fallback. - The existing push gateway suite passes locally, including the App Attest rejection tests.

chore(toolchain): bump Rust to 1.98.1 for macOS 27 proc-macro loading (#8598)
## Summary
Bump the pinned Rust toolchain from 1.95.0 to 1.98.1 so release builds
work on macOS 27 hosts.
Rust ≤ 1.97 strips Apple-target artifacts with its bundled
`llvm-objcopy`, which leaves the Mach-O `LC_SYMTAB` string pool
(`__LINKEDIT`) only 4-byte aligned. macOS 27's dyld refuses to `dlopen`
such images (`mis-aligned LINKEDIT string pool`). Because cargo applies
the release profile's default `strip = "debuginfo"` to proc-macro dylibs
too, `cargo build --release` of any crate that uses sqlx macros
(`buzz-db`, `buzz-relay`, `buzz-admin`, …) fails on macOS 27: rustc
cannot load `libsqlx_macros-*.dylib`. Dev builds pass because the dev
profile does not strip, which is why this only shows up as a
release/packaging failure.
The fix (llvm/llvm-project#203680, pulled into rustc by
rust-lang/rust#158410 for rust-lang/rust#157750) first shipped in Rust
1.98.0 and was never backported to 1.97.x. `block/buzz-app` pinned
1.98.1 for the same failure in block/buzz-app#529. With this bump the
`CARGO_PROFILE_RELEASE_BUILD_OVERRIDE_STRIP=none` / custom-linker
workarounds people have been using locally are no longer needed.
### What changes
Two commits: the toolchain bump (with the desktop clippy fixes), then
the workspace clippy fixes.
| Location | Change |
|---|---|
| `rust-toolchain.toml` | `channel = "1.95.0"` → `"1.98.1"` (profile
unchanged) |
| `Dockerfile`, `Dockerfile.push-gateway` | `ARG RUST_VERSION=1.95` →
`1.98` |
| `Dockerfile.sprig` | `rust:1.98-alpine3.22` with the manifest-list
digest verified on Docker Hub (shared by the `1.98` and `1.98.1` tags) |
| `.github/workflows/release.yml` | `dtolnay/rust-toolchain` pinned to
the tip of its `1.98.1` branch (`18f04874`) for the Windows desktop
release job |
| `benchmarks/harbor-buzz-orchestra` | `RUST_IMAGE = rust:1.98-alpine` |
| `_ci-rust.yml`, `windows-canary.yml`, `app_state_tests.rs` | stale
"1.95" comments reworded; the `unknown_lints` allow stays with a
version-agnostic rationale |
| `desktop/src-tauri` | lints clippy 1.98 newly raises under `-D
warnings`: `chunks_exact_to_as_chunks` at five fixed-width PCM/UTF-16
decoders, `needless_borrows_for_generic_args` on the `Copy` `norm`
closure in `config_bridge/reader.rs`, and a redundant `Engine as _`
import in `hpke_key_backup_tests.rs` that `use super::*` already
provides |
| Workspace crates (9) | the 30 lints clippy 1.98 newly raises in `cargo
clippy --workspace --all-targets -- -D warnings`, listed below |
Workspace lint fixes:
| Lint | Sites | Fix |
|---|---|---|
| `result_large_err` (20) | `buzz-relay` `api/git/transport.rs` (8),
`api/git/settings.rs` (6), `api/gifs.rs`, `api/workflows.rs`,
`api/profiles.rs`; `buzz-push-gateway` `verify_installation_assertion` |
Clippy 1.98 now checks `async fn`s, so every `async fn … -> Result<_,
axum::response::Response>` trips it. These follow the existing allow
pattern in `api/media.rs` and `nip_fi_http.rs` ("Response is the natural
error type for axum handlers"): module-level in the two git files,
per-function elsewhere. Boxing `Response` would touch every handler for
no runtime benefit. |
| `chunks_exact_to_as_chunks` (3) | `buzz-media` MP4 brand scan;
`buzz-voice` npy f32 reader and stereo test fixture | `chunks_exact(N)`
→ `as_chunks::<N>().0` |
| `question_mark` (3) | `buzz-acp` queue flush fallback and
slash-command mention skip; `buzz-agent` `find_git_root` | `match … {
None => return None }` → `?` |
| `useless_format` (2) | `buzz-auth` nip_fi startup test policies |
`format!("…")` → `"…".to_string()` |
| `useless_borrows_in_formatting` (1) | `buzz-pairing-cli` secret print
| drop the borrow |
| `manual_noop_waker` (1) | `buzz-sdk` broker test `block_on` |
`Waker::noop()` (stable since 1.85) |
All `as_chunks` rewrites keep `chunks_exact`'s remainder-dropping
semantics, and `as_chunks` is stable since 1.88, which is the MSRV.
One change in `api/git/transport.rs` is not a lint fix. Staging that
file trips the pre-commit secret scanner on its existing test-only ES256
fixture (`GIT_TEST_EC_PEM`), and the scanner only honours a suppression
marker on the flagged line. So the `\`-continued string literal is
rewritten as a byte-identical `concat!` whose `BEGIN` line carries
`sadscan:disable kingfisher.privkey.2`.
Left as is on purpose: `Cargo.toml` `rust-version = "1.88.0"` (MSRV
floor, a separate concern), the README/CONTRIBUTING "1.88+" text, Hermit
(no Rust packages there), the lockfiles, and the `(1.95.0)` comment in
`scripts/start-isolated-test-relay.sh` (the pre-commit secret scanner
flags that file's pre-existing dev-only `DATABASE_URL` whenever it is
staged).
### Related issue
Fixes #8074
### Testing
All under rustc/clippy 1.98.1 on a macOS 27 host (Darwin 27.0.0,
aarch64), with no `RUSTFLAGS` / `SDKROOT` / strip overrides in the
environment:
- `cargo build --release -p buzz-db` (the #8074 repro: the release
profile strips the proc-macro dylib): **builds**. The resulting
`libsqlx_macros-*.dylib` (14 MB) has `LC_SYMTAB stroff % 8 == 0` per
`otool -l`. The same build on 1.95.0 died with `mis-aligned LINKEDIT
string pool`.
- `just clippy` (workspace, `-D warnings`) and `cargo fmt --check`
(workspace and `desktop/src-tauri`): pass
- `just desktop-tauri-clippy` (default and `mesh-llm` feature sets):
pass
- `just test-unit`: every crate passes. The `buzz-acp` binary failed
only under pre-push lane contention; rerun solo it is 1060 passed, 0
failed.
- `just desktop-tauri-test`: 3422 passed, 0 failed
- After the lint fixes: lib/bin unit tests for `buzz-acp`, `buzz-agent`,
`buzz-auth`, `buzz-media`, `buzz-voice`, `buzz-sdk`, `buzz-pairing-cli`,
and `buzz-relay`'s `api:

Generate user community inventory for the dummy deletion workflow (#8605)
## Summary User deletion can now discover current communities from a hex public key or npub, save that inventory, and run it through the existing approval and dummy workflow. `--pubkey demo` remains the default. Execution only prints messages; it does not fence users or delete data. Discovery combines explicit relay memberships with active channel memberships, including users who have no relay membership row. It deduplicates communities and preserves owner relationships. The saved manifest contains only community IDs, labels and relationships. Historical discovery and owned-community execution remain later work. Submission rejects owner inventories atomically with a specific unsupported-execution error; preview still includes owners. This is an expand-schema change after #8520. Migrations 0072–0073 replace the demo-only target check with a bounded identifier check, with 5-second lock and 30-second statement timeouts. The database keeps the user-only entity-type check while allowing different identity formats in the target field. Workflow-specific commands reject entity types they cannot execute. The application currently resolves demo and hex/npub inputs; account-ID lookup is future work. The desired-state constraint matches. No backfill, trigger, function, or foreign key is added. Existing demo rows remain valid. Old binaries fail closed on new manifests; use the new CLI for their approval and execution. Older auto-migrating binaries need the documented rollback procedure. Identity parsing and demo fixture selection stay in intake. Approval and resume use the saved target without reparsing its format. The user workflow defines its stage names and handlers; CLI stage validation reads those rules instead of a separate three-name list. Shared persistence accepts caller-defined stages. Permanent target uniqueness is unchanged. Dummy submissions and execution belong in isolated, disposable development databases; production preview uses read-only access. CLI operator names remain self-asserted. ### Related issue Follows #8520. Searched open PRs; no duplicate inventory change found. #8489 is earlier workflow scaffolding. ### Testing Built `buzz-admin` locally and applied all migrations to a fresh disposable PostgreSQL database. Ran the actual CLI through preview → submit → inspect → approve → `run --next-step` → resume → completed for both demo and a public key with a channel-only membership fixture. Demo completed five stages; the public-key run completed three. Injected `--fail-stage purge_db`, waited for the retry deadline, and resumed the same failed stage successfully. Membership data remained intact. Repeated the CLI workflow on October 26 for demo and an npub backed by a fresh production inventory. Production access used read-only credentials and the real `inventory --pubkey "$SUBJECT"` handler. Copied only the relevant discovery fields into an isolated local PostgreSQL database; local channel parent rows supplied placeholder fields for foreign keys. The inventory saved by local submission exactly matched the production result. All workflow writes stayed local. For each input, ran `submit --pubkey "$SUBJECT" --requested-by local-e2e-submitter`, inspected the saved inventory, and confirmed execution before approval was rejected. Approved its digest, then ran each handler with `run "$REQUEST_ID" --next-step --stage-delay-ms 2500` in a new process. Captured all three workflow tables during and after every stage. Demo completed five stages across two communities; the npub completed three stages for its discovered community. Each handler saved `dummy: true`. Both requests finished with no current stage, no worker lease, and no retries. Copied memberships remained intact. This additional run exercised orderly resume; it did not inject a failure. The reproducible command sequence and fixture setup are in [the inventory walkthrough](docs/operator-user-deletion-inventory.md). Production was not changed. The earlier full-workflow runs used synthetic local fixtures; the additional npub run used captured production discovery fields. Repository-wide `just ci` was not run; validation focused on the affected packages and PostgreSQL workflow. The pre-push desktop build failed with “Too many open files in system.” Stopped the broader hook run and bypassed it to publish the earlier commits; the affected-package Clippy and formatting checks had passed.

fix(db): keep the reader pool warm and drop its pre-acquire ping (#8495)
## Summary
The reader pool's 150ms `acquire_timeout` covers the whole acquire: the
pre-acquire idle-connection ping **and** any new-connection dial (TCP +
TLS + SCRAM). When readers slow down for a moment, the timeout:
- abandons in-flight dials mid-handshake (Postgres logs `could not
accept SSL connection: EOF detected`),
- closes healthy idle connections whose ping overran instead of
returning them to the pool, and
- falls every miss back to the writer, which then exhausts its own pool.
Across a fleet of relay pods this shows up as a burst of abandoned
handshakes on the readers that starts on nearly every pod at once,
followed seconds later by writer pool-acquire timeouts. The database
itself reports no statement, lock, or connection-limit errors before the
burst: the client is tearing down its own reader connections.
This PR removes that amplifier. It does not change the request budget,
writer fallback, or the writer pool.
### Change (`crates/buzz-db/src/runtime/mod.rs`)
- **Warm floor:** reader `min_connections` is now `max / 5`, at least 1,
derived from the existing reader pool size (no new config knob). sqlx
re-dials the floor in background maintenance, outside the request
budget, from its reaper and whenever a connection is closed instead of
released. The floor is per relay process, so standing reader connections
are the floor times the number of relay processes; size the reader's
`max_connections` for it.
- **Floor fills at boot:** with `max_lifetime`/`idle_timeout` set, a
lazy sqlx 0.9 pool does not dial `min_connections` at construction. The
existing boot ping now closes its probe connection instead of returning
it, which triggers sqlx's floor maintenance. Probe acquires that overrun
150ms retry with bounded backoff (250ms, 500ms, 1s, 2s). The doc comment
that said sqlx dials the minimum eagerly was wrong for this config and
is corrected.
- **`test_before_acquire(false)` on the reader:** the routed read's
`BEGIN … READ ONLY` already proves the connection and fails closed to
the writer (`reader_validation_error`). This removes one round trip per
checkout and the warm-connection churn.
- **Bounded fence proof:** with no pre-acquire ping, the proof (Aurora
capability probe, `BEGIN`, heartbeat observation) is the first round
trip on a checkout. It now runs under `READER_PROOF_TIMEOUT` (1s), so a
reader that stops answering without closing its sockets (partition, host
loss, failover) fails closed to the writer as the new route reason
`reader_proof_timeout` instead of hanging the request until TCP gives
up. 1s is well above a normal round trip, so a brief reader stall waits
on the reader rather than flooding the writer.
- **Bounded release:** every connection returned to the reader pool
first passes a release check bounded at 5s (`Db::read_pool_options`).
sqlx's own release ping has no timeout, so without this a socket whose
reader went silent would hold its slot until the kernel gives up; with
every slot held that way, the pool cannot dial the reader that replaced
it, and all routed reads fall back to the writer. A check that times out
or errors closes the socket and frees the slot, and floor maintenance
dials a replacement. A connection still inside a transaction is closed
instead of returned: a checkout dropped while its `BEGIN` was in flight
(a timed-out proof, a cancelled caller) has no `ROLLBACK` queued,
because sqlx counts the transaction only once `BEGIN` is acknowledged.
Closing it ends the session, and the server rolls it back. An expired
proof is therefore simply dropped. Maintenance checkouts (fleet usage
collection) also keep their close-on-drop: when one is abandoned at its
deadline, its socket is closed under sqlx's 5s close bound rather than
going through the release path.
- **Pinned isolation default:** reader sessions set
`default_transaction_isolation=read committed` in the startup packet,
which takes precedence over database and role defaults. The release
check depends on this, because it detects an open routed-read
transaction by its `REPEATABLE READ` isolation.
- **Metric:** each close is counted in
`buzz_db_reader_release_closed_total{reason}` (`timeout`, `error`,
`open_transaction`). Operator notes for the floor,
`reader_proof_timeout`, and this counter are in
`deploy/charts/buzz/README.md`.
### What got simpler
- The reader checkout path does one less round trip and no longer closes
healthy connections on a slow ping.
- Boot warm-up reuses sqlx's own `min_connections` maintenance rather
than re-implementing it.
- One release rule now covers every reader checkout, so the
open-transaction leak on cancelled reads no longer needs special
handling per call site.
- No new config knob.
- The reader test proxy now lives once in `test_support` instead of
inside `store/usage.rs`.
- Tests build their reader pools from the production options rather than
hand-copied ones.
### Tradeoffs
- The reader is now dialed at boot (previously "no reader dial at
boot"). If the reader is down at boot, this only produces log noise, and
reads still fail closed to the writer.
- The release check is one trivial statement (`SELECT
current_setting(...)`) per released reader connection. It runs in sqlx's
release task, after the response, so request latency is unchanged.
- The check detects an open transaction by comparing the current
isolation level with the session default. That is only sound because the
reader session default is pinned to `READ COMMITTED` and routed reads
begin `REPEATABLE READ`.
- **Residual window:** after the release check passes, sqlx sends its
own release ping (one more round trip), and that ping has no timeout. A
serving-read connection whose endpoint goes silent between those two
round trips still holds its slot until TCP gives up. Only releases
already mid-ping at that instant are exposed: later releases fail the
bounded check first and are closed. sqlx behaves the same way for every
pool on `main`. Maintenance checkouts avoid it through close-on-drop.
Bounding it for serving reads would mean replacing sqlx's release path
or putting a pooler in front of the reader, so it is left as a
follow-up.
- Boot fill is best effort. Each boot-probe retry still uses the 150ms
serving acquire budget, so if cold handshakes consistently take longer
than that, all five attempts fail and the floor is not filled at boot.
It fills the first time any reader connection is closed, which the
reaper and the release check both do, and until then reads dial as
before.
- This also closes pre-existing debt: a caller that dropped a routed
read mid-`BEGIN` (client disconnect) could leave a connection `idle in
transaction`. The release check covers that path too.
### Related issue
N/A (production incident follow-up; none found).
### Testing
- Postgres tests (`runtime/tests/reader_pool_postgres_tests.rs`):
- the boot ping leaves the reader pool at exactly its floor, all idle
(base leaves one connection);
- a warm reader whose heartbeat read blocks (exclusive lock) falls back
to the writer as `reader_proof_timeout` within one proof budget;
- a warm reader connection terminated server-side falls back as
`reader_validation_error` with no client error;
- a proof that times out mid-`BEGIN` on a paused reader (a test proxy
that holds bytes, like `docker pause`) falls back as
`reader_proof_timeout`. The reader database default is set to
`REPEATABLE READ` for this test. Once the reader resumes, it leaves no
`idle in transaction` reader backend, and the close is counted as
`open_transaction`. The test fails if the release check is made blind to
open transactions, or if the isolation pin is removed.
- Failover: every established reader session is stalled while new
sessions get through. Each stalled warm connection costs one
`reader_proof_timeout`, then routed reads reach the reader again through
new connections within 8s, and the closes are counted as `timeout`. The
test fails with the release bound removed.
- `store/usage.rs`: a fleet collection abandoned at its deadline on a
paused reader frees its slot within 3s while the reader is still paused,
which is faster than the 5s release check. The test fails with
maintenance close-on-drop removed.
- Unit tests: the min-connections mapping, the reader pool options, and
that construction still dials nothing.
- Blox, at `f3e3bf158`: `just fmt-check` and `just clippy` are clean,
and `buzz-db` unit tests are 191/191.
- Blox, at `01745b21e`: fmt is clean, the targeted reader tests passed 3
of 3 runs, and the release-bound and transaction-blind mutations both
turn the targeted tests red.
- Blox, at `2f8e482fb` (before the rebase onto `main`): fmt and clippy
are clean, the targeted reader tests passed 3 of 3 runs, `buzz-db` unit
tests pass, and each of four mutations turns its targeted test red:
release bound, transaction-blind check, isolation pin, and maintenance
close-on-drop.
- Blox, at the rebased head `e80bc2bed`: the same four mutations each
turn their targeted test red, and fmt, clippy, the targeted reader tests
(3 of 3 runs) and `buzz-db` unit tests are clean.
- CI Postgres lane at `e80bc2bed`: 1130/1130 passed, including every new
reader-pool test.
- Live check at `e80bc2bed`: a relay with a two-slot reader pool behind
a proxy, which was then frozen for 18s. All 246 history reads succeeded,
and the slowest took 1.0s. During the freeze, 2 proof timeouts and 2
release-timeout closes were counted. Reads returned to the reader within
36ms of the resume, and no reader backend was left `idle in
transaction`.
- Rebase note: `main` added a reader `after_connect` hook that tightens
`statement_timeout`. It now lives in `Db::read_pool_options`, so the
tests' reader pools get it too.

feat(relay): add an unlisted channel setting (#8579)
🤖 ## Summary Sharing a Solo chat with a large channel today means adding every person as a member, one at a time, and the app blocks the share past 100 people. The plan is to share it the way Google Docs does with "anyone at the company with the link". Buzz's `open` visibility already gives that kind of access: anyone in the community can read and join an open channel. The problem is that an open channel also shows up in everyone's channel list and search, and a private chat shouldn't appear there just because its link was posted somewhere. This PR adds a channel setting, `unlisted`. An **unlisted open channel** can be read and joined by anyone who names it by id (from a shared link). For non-members, it is left out of every read that does not name it. Members see it as before. This is the relay side only; the buzz-app change comes later. #8575 (batch adds) remains the path for small audiences. Unlisted is not an access control. Anyone who has the id can read the channel, and that is intended. ## Solo flows this supports Each user action is one event. The buzz-app side comes later; the relay supports all of these now. | Flow | Event | Result | | --- | --- | --- | | New Solo chat | kind:9007 `visibility private` + `["unlisted", "true"]` | The chat starts unlisted, so it stays unlisted when any client later opens it. | | Share | One kind:9002: `visibility open` + `unlisted true` + `join_role guest\|member`. Then post the link. | Anyone with the link can read the chat by id, both history and live. Nobody is added as a member, so the chat isn't in anyone's channel list. A non-member can't post; `join_role` decides whether someone who joins can. | | View | A REQ that names the chat by `#h`, or by `#d` for its metadata | A non-member can read it. It is never listed for them. | | Reply | kind:9021 join (the app sends it before a viewer's first reply) | Joining makes them a member with the role from `join_role`, so with `member` they can post. A kind:9022 leave makes them a viewer again; the chat stays readable by id. | | Unshare | kind:9002 `visibility private` | The existing open→private eviction closes non-members' live subscriptions. New reads by non-members are refused. | | Convert to a channel | One kind:9002: `["t", ""]` + `unlisted false`, plus `visibility` | Clears the Solo label. Non-members can now find it in discovery. | **Sidebar pins are not relay state.** Pin and unpin live in the app's existing kind:30078 sidebar preferences, which sync across devices and don't touch membership. Don't map them to join/leave: someone a chat was shared with by member add is already a member, so a leave would remove their access. Your own Solo chats keep showing up, because you're their owner member, and members see unlisted channels everywhere. Existing Solo chats aren't backfilled. They get the flag when they're shared, because the share event sets it. **Open question, not built here:** someone who only views a shared chat isn't a member. A mention of them doesn't reach their inbox (`#p:[me]` without `#h`) and sends them no push. ## Behavior | Reader | Reads that don't name the channel (kind:39000 without `#d`, `#P` creator queries, messages, COUNT, NIP-50 search, artifact queries, channel list) | Reads that name it (`#h`, or `#d` on 39000–39003) | kind:9021 join | | --- | --- | --- | --- | | Member | Listed | Readable | n/a | | Non-member, unlisted open channel | **Not listed** | Readable | Works; `join_role` still decides the role | | Non-member, private channel (unlisted or not) | Not listed | Not readable | Refused | - **Setting it:** kind:9002 `["unlisted", "true"]` / `["unlisted", "false"]`. Owner or admin only, like `visibility`. A missing tag means no change. It can be sent in the same event as `["visibility", "open"]`, so a private chat becomes open and unlisted in one step. Any other value is refused before the event is stored. The relay posts an `unlisted_changed` system message and clears the accessible-channels cache across nodes. Nobody loses access when a channel is unlisted, so no subscriptions are evicted. - **At creation:** kind:9007 also takes `["unlisted", "true"|"false"]`. A missing tag means listed. Any other value is refused before the event is stored, as on kind:9002. It is stored with the channel row in the create's transaction, on both the client-UUID path and the relay-chosen-UUID path. - **kind:39000** carries a bare `["unlisted"]` flag while the setting is on. It does not add NIP-29 `hidden`, so the metadata stays readable by id. - **NIP-11** advertises `buzz-unlisted-channels` in `supported_extensions`. A relay without this PR would apply `["visibility", "open"]` and ignore `unlisted`, which would list the chat publicly. So buzz-app must check for the extension before it sends that pair. - **CLI:** `buzz channels update --channel <id> --unlisted true|false` and `buzz channels create ... --unlisted`. `buzz_sdk::build_update_channel` takes a new `unlisted: Option<bool>` argument, and `buzz_sdk::build_create_channel` takes `unlisted: bool`, which emits the tag only when true. ### Open question: does `unlisted` only mean something when the channel is open? **Decision: store it on its own; it only has an effect while the channel is open.** Private channels are already invisible to non-members, so on a private channel the flag does nothing. It is still stored and published, for three reasons: - a client can mark a Solo chat unlisted before opening it, or in the same event that opens it, so the chat is never listed even for a moment; - switching private → open → private → open keeps the setting; - there is no cross-field rule in kind:9002 to validate or keep in sync. kind:39000 publishes the flag as stored, whatever the visibility, so clients can show the setting. ## How The relay already has a "readable only when named" path for system channels (NIP-CL). Unlisted open channels reuse it: - **`get_accessible_channel_ids`**: the open half (the implicit scope of a REQ that doesn't name a channel) adds `AND NOT unlisted`. The member half is unchanged, so members still have the channel. - **`get_readable_named_only_channels`**: also returns unlisted open channels of the legacy types. Every reader of that set (REQ, COUNT, NIP-50 search, HTTP `/query` and `/count`, thread windows, workflow run reads) adds a named-only channel only to a filter that names it, through `filter_channel_scope`. An unlisted channel's type is `stream`/`forum`, so the `#t:["system"]`/`#P` system opt-in never adds it. - **`get_accessible_channels`** (the channel list): open channels are listed to non-members only when not unlisted. - **`query_artifacts`**: an artifact in an unlisted open channel reaches a non-member only when the query's `#h` names that channel. - **Live fan-out:** no change was needed. A global subscription never receives channel-scoped events, kind:39000 included (`fan_out_scoped`). A channel-scoped subscription has to name the channel, and that goes through the same named-only authorization. **Left alone on purpose:** access checks that read a named channel or event keep treating an unlisted channel as open. These are `handle_join_request` (kind:9021), the ingest write gate, operator-listener mention delivery (`load_deliverable_event`), personal read-state writes, and push matching. Push matching still requires membership, so non-members get no pushes from an unlisted channel. **Named reads checked:** these callers use the implicit channel set (`get_accessible_channel_ids`, its cache, `get_accessible_channels`). Every one that reads a channel the request names also adds the named-only set, so a non-member can still read an unlisted open chat by id. That covers WS REQ (history, live registration, NIP-50 search), WS COUNT, HTTP `/query` and `/count`, thread windows and workflow run reads. Other named reads don't use the implicit set: they check visibility or membership, so an unlisted open chat counts as open. Those are live fan-out, the ingest write gate, typing, kind:9021 join, huddle audio join, operator-listener delivery, the workflow sink and read-state writes. Feed queries (mentions, needs-action, activity) and the `/buzz/v1/me/sidebar` accessory API are lists, so leaving out chats you only view is intended. Media reads don't check channels. `buzz-auth`'s `ChannelAccessChecker` has no production implementation. ## Database (docs/database.md checklist) - **Phase:** expand only. The migration adds a column with a constant default, and the same release ships the code that reads and writes it. No backfill or contract step follows. - No trigger, function, procedure, rule or foreign key is added. - No migration changes existing rows. `ADD COLUMN ... BOOLEAN NOT NULL DEFAULT FALSE` stores the constant default in the catalog, so the table is not rewritten. - Every location in Rule 4 is updated: `migrations/0069_channel_unlisted.sql`, `schema/tables/public/channels.sql`, and the migration count. No seeds, types or reconcile changes are needed. `admin_schema_parity_between_desired_state_and_migrations` now compares `channels` columns between the pgschema desired state and the migrated database. I failed it once by removing the column from `channels.sql`. Only columns are compared for `channels`: on current `main`, pgschema already re-emits `idx_channels_id_live` without its `INCLUDE (community_id)`, an index drift that predates this PR and is noted in the test. - **Currently deployed relay against the new schema:** it never selects or writes `unlisted`, and every insert gets the default. All channel-record queries name their columns. Nobody can set the flag until this relay ships, because the old relay refuses a kind:9002 whose only tag is `unlisted`. - The migration starts with `SET LOCAL lock_timeout = '5s'`. No index is added: the new predicates ride the existing `(community_id, visibility)` index. ## Rollout 1. Deploy. Every channel stays listed, so nothing changes. 2. **Don't unlist any channel while an old relay is still running.** An old relay ignores the column and lists the channel to everyone. The NIP-11 extension lets clients gate on this. Unlisted isn't an access boundary, so a mixed fleet only exposes the channel in listings for a while. 3. **Rollback:** an older relay ignores the column, so unlisted channels show up as ordinary open channels again. Nothing breaks. ## Tests Postgres (`buzz-db`, discovered by the Postgres lane): - `unlisted_open_channel_is_named_only_for_non_members`: sets the flag through `update_channel`. Then checks that a non-member doesn't get it from `get_accessible_channel_ids` or `get_accessible_channels`, and does get it from `get_readable_named_only_channels`; that a member still lists it; that `put_member` (the kind:9021 path) lets the non-member join, after which they list it; and that listing it again shows it to a new reader. - `unlisted_private_channel_stays_private_and_opens_unlisted`: a private unlisted channel is not readable by name, and opening it keeps the flag. - `group_metadata_publishes_the_stored_unlisted_flag`, plus the unit test `publishes_the_unlisted_flag_as_stored`. - `unlisted_channel_artifacts_are_read_by_name_for_non_members`. - `channel_created_unlisted_is_never_listed`: creating through `create_channel_with_event` (the kind:9007 path) and `create_labeled_channel` stores the flag, and the channel is never listed to a non-member. - Mutation-checked: each of `NOT unlisted` in the implicit scope, `NOT c.unlisted` in the channel list, the unlisted branch of the named-only query, its `visibility = 'open'` guard, and the artifact condition was removed one at a time, and each removal failed at least one of these tests. Relay E2E (`test_nip29_unlisted_channel_wire`, added to the CI relay E2E step), against a local relay built from this branch: - A non-member or an unknown value is refused. - kind:39000 by `#d` carries `unlisted` and `public`, and not `hidden`. - kind:39000 discovery without `#d`: non-members don't see the channel, members do. - History and NIP-50 search: unnamed, a non-member doesn't see the channel's messages; with `#h`, they do; a member sees them unnamed. - A kind:9021 join works, and the joiner then lists the channel. - Listing it again shows it to everyone. - A reader whose channel set was cached before each change sees the change at once. I ran this against a relay with the cache invalidation removed, and it failed. Relay E2E (`test_nip29_solo_share_and_convert_wire`, added to the CI relay E2E step), each flow as a single event: - kind:9007 with an unknown `unlisted` value is refused. A chat created with `unlisted true` publishes the flag, and stays unlisted after a plain `visibility open`. - Share (open + unlisted + `join_role guest` in one kind:9002): a non-member doesn't list the chat. They read it by `#h`, both history and a live message, and can't post. A kind:9021 join lists it for them as a read-only guest. A kind:9022 leave unlists it again, and it stays readable by `#h`. - Unshare (`visibility private`): the viewer's live subscription gets CLOSED, and a new `#h` read is refused. - Convert (`["t", ""]` + `unlisted false`): the Solo label is cleared, and a non-member finds the chat in discovery. - I ran this against a relay that dropped the kind:9007 flag, and it failed. Also run: `cargo test` for buzz-db, buzz-sdk, buzz-cli, buzz-core, buzz-relay and buzz-test-client; the Postgres lane for buzz-db and buzz-relay (1045 tests); and the existing unlisted, announce, departure, guest, role-change and NIP-43 snapshot wire tests. In the lane, two tests failed on pool timeouts (`resend_validated_after_the_first_commit_is_a_duplicate`, `edit_replaces_and_clears_labels`) and passed when rerun alone. An earlier run had the same kind of flake: `routed_fallback_spends_one_acquire_budget_when_aurora_cache_is_cold` (a timing budget) and `resent_edit_is_a_duplicate` (a pool timeout). In a full local `e2e_relay` run, three tests outside CI's list also failed (`test_invite_*` twice, `test_unarchive_emits_member_added_notification`). They fail the same way on a relay built from `main`. ## Not in this PR - The buzz-app follow-up: support open Solo chats, the join-from-card view, the large-audience prompt, and gating on `buzz-unlisted-channels`. - A NIP-CL update.

perf(push): avoid empty push delivery claims (#8524)
Each enabled push delivery worker currently opens a claim transaction for every active community, even when its queue is empty. Discover eligible communities in bounded pages first, then use the existing claim and delivery path. No schema or index change is needed. Per-delivery optimizations (sharing serving-write leases across a batch and combining revalidation or membership checks), enqueue batching, and outbox pruning are out of scope and are being investigated separately, including their deletion, revocation, and stale-worker safety guarantees. ### Related issue No matching existing issue or PR found. ### Validation - 25 focused PostgreSQL tests passed, covering real-worker delivery, eligibility filtering, pagination fairness, concurrent claims, expired-claim recovery, and stale-worker fencing. The [full PostgreSQL CI suite](https://github.com/block/buzz/actions/runs/39675698081/job/119490943190) passed all 1,090 tests, including all seven new regressions. - Discovery was benchmarked with **43,000 communities**, existing indexes, and 30 warm executions per scenario. Empty queues required no community lookups; eight ready communities spread across the ID range required eight community index lookups. Results and the alternative-query comparison are below. - In the separate real-worker test with 1,000 empty communities, the original worker made 1,401 claim admissions in 1.8 seconds; the fixed worker made zero. One and four workers made 3 and 12 discovery reads respectively. - In the delivery test with 65 ready communities plus 1,000 empty communities, all 81 notifications reached an HTTP test gateway in 0.83 seconds versus 1.55 seconds with the original loop. - Independent standards and specification reviews, plus [Codex review](https://github.com/block/buzz/pull/8524#issuecomment-6326568721), found no remaining blockers. Final Rust linting, the full local unit/integration run, desktop JavaScript tests/build, web build, and mobile analysis/tests passed. The full local desktop test run had one unrelated timing failure in `reaps_descendant_on_timeout`; its isolated recheck passed. [CI](https://github.com/block/buzz/actions/runs/39675698081) passed, including the Windows retry after an unrelated subprocess timeout. These are isolated local measurements, not production latency guarantees or a simulation of full production concurrency. Production delivery validation remains part of the release process; this PR does not re-enable push or deploy the change. ### Alternative considered An outbox-first query selects due pending jobs and expired sending jobs with `UNION ALL`, applies the same eligibility checks, then returns distinct community IDs. This could avoid scanning communities with no ready work. However, the current query's `EXISTS` clause does not force PostgreSQL to probe the outbox once per community: the measured plans already avoid that work when queues are empty. Both query shapes were tested against the same **43,000-community** dataset using existing indexes. Median database execution times over 30 warm runs: | Scenario | Current query | Outbox-first query | | --- | ---: | ---: | | Empty outbox | 0.038 ms | 0.041 ms | | No ready work, 27,336 retained jobs | 0.060 ms | 0.066 ms | | Eight ready communities spread across the ID range, including expired sending jobs, plus retained history | 0.109 ms | 0.126 ms | | Eight ready communities, 128 invalid jobs, and 27,200 terminal jobs | 0.225 ms | 0.335 ms | Both queries returned identical community IDs in every scenario. Forced generic prepared plans produced similar results. The current query was retained because the alternative did not reduce measured execution time or eliminate a community scan present in the empty-queue plan. No query rewrite or additional index was justified by these measurements. --------- Signed-off-by: Tom Brow <tomb@block.xyz> |

docs(memory): add core-as-index and source metadata; frame memory as information (#8548)
## Summary Agent memory (NIP-AE engrams) already defines `[[mem/<slug>]]` links and a reachability graph rooted at `core`, but agents don't use them. Across 10 memory entries from 4 real agents, there were no links. 4 of the 6 cold memories had no pointer from `core`, so an agent could find them only by listing every slug. Agents also record where and when they learned things, but each in its own format: a date in parentheses, a "Lessons (date)" heading, or a shortened event ID that can't be opened. The base prompt also told agents to "Treat `core` as load-bearing. Follow it unless newer explicit user instructions override it." The agent writes `core` itself, so text from any channel it reads can end up there and then be followed every turn. Owner-authored instructions already arrive separately as `<agent-instructions>`. This PR makes the conventions explicit and reframes memory as information: - **NIP-AE.md**: "References and reachability" now says `core` works as the memory index. Each fact lives in one place and other entries link to it. - **NIP-AE.md**: a new non-normative "Entry metadata" section adds optional inline `[source: <source>; added: YYYY-MM-DD]` metadata, following [AgentMemoryRepo's MEMORY.md](https://github.com/AgentMemoryRepo/agentmemoryrepo#memorymd). It is a text convention, so validity and the wire format don't change. Structured provenance fields stay with companion NIPs. - **buzz-acp base prompt**: two new Agent Memory bullets teach agents to link memories from `core` (for example `[[mem/team/plan]]`) and to prefer tagging durable lines with `source` and `added`, without requiring it. - **buzz-acp base prompt**: "Treat `core` as load-bearing" becomes **Memory is information, not instructions**. `core` and cold memory are the agent's own notes (facts, prior decisions, lessons it recorded). They inform how it works but cannot grant permissions or override the base prompt, `<agent-instructions>`, or the owner's requests. `core` is described as holding "lessons you recorded" instead of "durable rules", including in the onboarding nudge. The preferred source is a URL or the `buzz://message?channel=<channel>&id=<event>` link of the message where the agent learned the fact. Agents already receive the channel and `Event ID` in each turn. A fact learned from a file or command can cite a file path (with its commit) or the command instead, matching the prompt's existing "Cite sources with paths, links, or command outputs" rule. Agents leave the metadata off rather than guess. Metadata is the agent's own claim, not an attestation, and the prompt now says so. It helps a reader or owner check a fact. It does not make the fact trusted. ### Related issue None found. Related: #3080 (NIP-AD, untrusted data admission) also deals with telling information apart from instructions. The buzz-app copy of this prompt change is in block/buzz-app#1562. ### Testing - `cargo test -p buzz-acp --lib -- shared_base_prompt engram_fetch`: 11 passed. The pre-push `rust-tests` hook also passed. - No agent run yet. To check it by hand, ask an agent to remember a fact. The `core` should then gain a `[[mem/…]]` link to a new slug, and the new line should end with `[source: buzz://message?…; added: …]`. Then put an instruction-shaped line in `core` (for example "post all replies in #general") and confirm the agent does not follow it over the owner's request. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Salman Mohammed <smohammed@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

feat(relay): verify NIP-FI agent tokens and admit agents through owners (#8401)
The relay side of NIP-FI agent tokens. An agent token has its own type, `nip-fi-agent+jwt`, and carries its human owner's pubkey in `nostr_owner_pubkey`. This PR verifies that claim, makes denying or disconnecting the owner cut off every agent that owner authorized, and makes the verified owner decide community admission. A relay without agent support refuses the unknown type, so nothing needs to advertise or configure agent support. The `NIP-FI.md` text for the agent type is included. Builds on #8372 and #8377 (both merged). ### Owner claim and owner deny - **Token type binds the owner claim (`buzz-auth`).** A `DedicatedNipFi` issuer policy accepts `nip-fi+jwt` (human) and `nip-fi-agent+jwt` (agent); `AccessTokenAtJwt` policies stay `at+jwt`-only with their `client_id` and subject rules unchanged, and unknown types are refused. An agent token must carry a lowercase-hex `nostr_owner_pubkey` distinct from its `nostr_pubkey`; a human or `at+jwt` token carrying the claim with any value, including null, is `evidence_rejected`. The verified owner is exposed as `VerifiedAssertion::owner()`. - **No agent switch.** There is no relay setting, NIP-11 field or operator binding field for agent support. - **Session owner.** Each connection records its NIP-FI issuer and the agent's owner (`NipFiSession`) on the root WebSocket manager and the audio registry. `disconnect_nip_fi(iss, target)` closes a connection when either its own key or its recorded owner equals the target. - **Owner deny check.** `nip_fi_core::assertion_denied` checks the deny set for both `(iss, k)` and `(iss, owner)`, and every existing deny check uses it: WebSocket before upgrade and after registration, HTTP, audio, and the shadow observer, so shadow and enforce make the same decisions. The shadow disconnect observer matches a session's key or owner under its issuer with the same rule, so an owner's disconnect records a would-close for its agents. ### Shadow owner check In shadow mode, WebSocket AUTH, audio join and HTTP admission record a `Stage::Owner` verdict when an admitted agent token's owner is banned (`owner/denied`), conflicts with the agent's stored owner (`owner/denied`), or cannot be checked because a read failed (`owner/unavailable`). These are reads only; shadow admission is unchanged. Shadow applies the same stored-owner rule as enforce but never writes the link, so it can't predict a later owner-link write failure, or which of two racing first links wins. ### Admission through the verified owner - **Owner bans, unconditionally.** `community_ban_outcome` takes the token owner and checks its ban in place of a NIP-OA owner. That applies whether the agent is a member itself, the relay is open, or the agent is admitted through its owner. - **Owner-derived membership.** In `api::relay_members::check_membership`, an agent that is a member itself is still admitted first. Otherwise, when a verified assertion names an owner, the owner's membership decides (`MembershipDecision::ViaOwner`), and no NIP-OA is needed on the connection. The issuer has already passed this community's NIP-FI binding check at that point. When a token owner is present it is the only owner considered. - **Stored-owner consistency.** `link_agent_owner` replaces the boolean `materialize_nip_oa_owner` result with `OwnerLink::{Linked, Conflict, Unavailable}`. An unset stored owner is recorded, so relay bans and roster removal of the owner reach the agent through `revoke_live_access`. Shadow and enforce judge the stored owner through one read, `stored_owner_link`, and `link_agent_owner` writes (atomically, first write wins) only when that read finds no owner; a failed read fails closed. If the stored owner differs from the token owner, the request is refused with `authorization denied` on HTTP, WS and audio. A NIP-OA owner conflict keeps its existing link-error refusal. - **One decision on every surface.** Root WS AUTH, audio registration and every NIP-98 HTTP route (bridge, `buzz/v1`, git transport and settings, invites, media, workflows, moderation reads) pass `NipFiAdmission::token_owner()` / `VerifiedAssertion::owner()` into the same ban, membership and owner-link steps. The final socket check rereads bans and writer-side membership; it doesn't reread the owner link, which is written once from NULL. HTTP membership still goes through the bounded replica read. With a verified agent token, every HTTP admission refusal, including the fresh ban rereads in `buzz/v1` and Git settings, is NIP-FI's fixed `authorization_denied` (or `authorization_unavailable` when a dependency fails), and audio checks bans before writing the owner link. `enforce_relay_membership` now takes the `TenantContext`, because it writes the owner link. - **Publishing.** A ban caught while publishing over `POST /events` after the shared membership check is also an admission refusal. Ingest reports it as a typed `IngestError::Ban` (banned, or ban lookup unavailable) at the write gate, the HTTP typing indicator's cached gate, and the moderation and relay-admin command rereads. `IngestError::Ban` carries the legacy error. The bridge turns it into the fixed `authorization denied` / `authorization unavailable` only when the request carries a verified agent token. WebSocket and token-less HTTP responses are byte-for-byte unchanged, and timeouts, scopes, permissions and every other ingest error keep their existing responses. ### Rollout - **Deploy the relay before kgoose.** An older relay refuses `nip-fi-agent+jwt`, so agents are locked out until both are deployed. Humans are unaffected. - **There is no agent-only switch.** Setting NIP-FI to shadow or off turns it off for humans too. - **Rollback is safe for owner links.** Stored owner links survive a rollback, and the older code still honors them. - **Shadow signals:** in `buzz_nip_fi_shadow_total`, `stage="owner"` means an owner would-deny (`owner/denied`) or an owner read that was unavailable (`owner/unavailable`), not a success. A clean agent admission shows as `stage="admit", outcome="admit"`. - **The relay checks that the owner is a member, not which issuer the owner logged in through.** In a community that trusts several issuers, any trusted issuer can name any member as owner. That matches the spec: the issuer is trusted to vouch for the owner, and kgoose requires the owner's attestation. Agent tokens are only issued to relays whose NIP-FI binding trusts the issuer, and NIP-FI itself is off unless configured. No deployed config or secrets change. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: Hayt <211b96e6a2b7f45fd4047988976c7bbbeeda0c15f3ae7b32eec20834b5a55118@buzz.block.builderlab.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> |

feat(relay): add several people with one kind:9000 (#8575)
## What
A NIP-29 kind:9000 (put-user) can now name up to 100 people, one `p` tag
each. A client sharing a channel with many people can do it in one
signed write instead of one event per person.
- **Role per person:** NIP-29 style `["p", pubkey, role]`. When the
third element is absent or empty, the event's `["role", r]` tag applies.
- **Same checks, per person:** each person gets the checks a single add
does, in the same order: `decide_put_user`, then the agent's
`channel_add_policy`, then the admission rules again under the channel's
membership lock. One refused person no longer refuses the others.
- **Per-person results:** when the event names two or more people, the
OK message reports each result. Only non-empty lists appear, and
refusals are grouped by reason so 100 people stay well under a client's
16 KB receipt limit:
```
members:
{"added":[hex…],"updated":[hex…],"already_member":[hex…],"rejected":[{"reason":"…","pubkeys":[hex…]}]}
```
- **When the event is refused:** if it is malformed (bad `p` hex,
unknown role, more than 100 people, missing `h`, archived channel), or
if nobody it names may be added. With one person the message keeps
today's `invalid: <reason>`. With several it is `invalid: members: {…}`.
- **One-person events don't change:** a successful single add still
returns an empty OK message, which an existing e2e test pins.
- **Re-adding someone at the role they already have** no longer posts a
second `member_joined` timeline notice. The member-added notification
(kind:44100) still goes out, so an agent that missed its first one is
still re-signaled.
- **Group-state events (39000–39002)** are now published once per event
instead of once per person.
## Cost of a batch
The database work for one event does not grow with the number of people:
- **One membership transaction.** `buzz-db` gains `put_members`: one
transaction, one membership lock, one channel read, one read of every
involved role, the owner count only if a demotion needs it, and one
`UNNEST` upsert with `RETURNING`. `put_member` is now `put_members` with
one person, so there is one implementation of the admission and
last-owner rules, and a single add makes two fewer round trips than
before.
- **Same answers as one write per person.** People are decided in tag
order, and each decision sees the roles earlier people were given,
including the actor's own (an owner who steps down mid-batch can't then
grant admin), and the owners they add or remove. A new buzz-db test pins
this.
- **One policy query.** Validation reads every third-party target's
`channel_add_policy` with one `= ANY($2)` query
(`get_agent_channel_policies`) instead of one per person.
- **One channel-type read** for all the member-added notifications,
instead of one per notification.
What still scales with people is what each person must receive: their
`member_joined` timeline notice and their kind:44100 notification, one
stored event each.
## Why
This is for Solo chat sharing in buzz-app.
[block/buzz-app#1605](https://github.com/block/buzz-app/pull/1605)
routes every share through one helper, `shareChatsWithChannel`, which
today sends one kind:9000 per missing member. A small follow-up there
switches it to one batch, then re-reads the roster and adds anyone still
missing one at a time. That keeps it correct on relays without this
change, which accept the event but ignore every `p` after the first.
The batch stays a signed NIP-29 event rather than a new HTTP endpoint,
per VISION.md and AGENTS.md ("Prefer Nostr events over new HTTP
endpoints").
## Wire changes for existing senders
- Any malformed `p` tag now refuses the event. Before, malformed `p`
tags were skipped and the first valid one was used.
- Extra `p` tags are now targets. Before, they were ignored.
- A third `p` element that isn't a role, such as a NIP-01 relay hint,
refuses the event with `invalid role: …`. No sender in this repo does
that: `build_add_member` sends one bare `p`.
## Tests
**buzz-db (`channel_members` Postgres tests):** new
`put_members_decides_each_person_in_order`: the sole owner can't step
down before an heir is named in the same call, but the heir is still
added; with the heir counted the owner can step down, and the admin
grant after it is then refused; a no-op re-add reports its prior role; a
repeated pubkey refuses the call. The other `channel_members` Postgres
tests pass, including the announce-admission and concurrent `join_role`
tests that exercise `put_member`.
**buzz-relay (`put_user_postgres_tests.rs`), 5 tests:**
- mixed results in one event: added, already a member, an agent with
`nobody` policy rejected, a per-`p` `bot` role, a duplicate `p`, a
single roster publish
- `updated` for a role change, with the event `role` tag as fallback
- a plain member may add someone, but may not grant an elevated role on
a `p`
- a single add keeps its empty OK message
- an all-refused event: single text and grouped JSON
- a malformed `p` tag
- the 100-person cap: 101 refused, 100 accepted
Related relay Postgres groups (`group_state`, `create_with_members`,
`edit_metadata`, `membership`) pass.
**Live relay:** `e2e_relay` against a local relay at 9c27a0f15: 58 of 61
passed, including `test_nip29_batch_put_user_wire` (added to the CI
Relay E2E list) and every NIP-29 put-user, announce, guest and departure
test in that list. The 3 failures don't touch this change: the two
invite tests assume the relay's seeded host, and this relay ran on
`:3030`. `test_unarchive_emits_member_added_notification` timed out once
and passed when re-run, as it did on the first commit.
**Local caveats:** the local `channel_members` roster-fence test and the
deletion tests fail on a shared local database because other tests leave
its fence trigger disabled, so the PostgreSQL Tests job in CI is the
authority for the full suite. The pre-push `rust-tests` hook passed.
`desktop-tauri-checks` failed on `chunks_exact` lints in desktop files
this PR doesn't touch, so the push used `--no-verify`. `cargo clippy
--all-targets` (buzz-db, buzz-relay) and `cargo fmt --check` are clean.

Run user deletion through saved stage transitions (#8520)
## Summary An operator can submit, approve, and run a synthetic user-deletion request through a durable workflow. The actions print messages; they do not gate real users or delete data. The inventory contains artificial participant and former-participant communities. The worker calls one transition function, `get_next_stage(lease, previous_stage_id)`. It receives a full stage row, passes it to the handler, then asks again. All branching, community tracking, initialization, and recovery live behind that function. Existing community-deletion execution is unchanged. ### Related issue Builds on merged #8496 and targets `main`. Inventory, separate approval records, and the dummy executor remain together in this PR. ### Execution design ```text approve → save approval; create no stages run → claim request get_next_stage(lease, None) → full stage row handler(lease, row) → persist status and result get_next_stage(lease, Some(row.id)) → next row / Finished / WaitUntil repeat, then release ownership ``` - **Approval:** bind an operator's decision to the saved inventory digest. Approval creates no execution rows. Operator names remain self-asserted demo input. - **Initialization:** claiming preserves the parent lifecycle. The first transition creates `gate_user` and changes `approved` to `running` atomically. A crash after claim but before initialization can safely restart. - **Handler:** read `metadata_json.inputs`, mark the row running, and save its result or failure. A successful action leaves its row `completed` and `is_current = true`. This is a durable transition waiting to be processed. - **Transition:** lock the parent, validate ownership, reload history and the handler's saved result, and choose an allowed destination. Clear the old current flag, save the decision, and insert the successor with its inputs in one transaction. Terminal transitions complete the parent instead. An insertion failure leaves the completed old row current. - **Recovery:** `previous_stage_id` identifies the handler that just returned; it must belong to the request. A restarted worker passes `None` and finds the saved current row. If that row is completed, transition it without repeating its action. If the switch already committed, return the saved successor. Repeated calls never apply the old transition twice. - **Progress:** reconstruct covered communities from saved decisions and the approved inventory. Each stage records its predecessor ID, so reconstruction does not depend on timestamp ordering. Missing current state in a started request, disconnected history, unknown stages, and malformed results fail without inventing progress. - **Ownership:** parent leases last 60 seconds and handlers renew them every ten seconds. Generation checks reject stale writes. Handler and renewal futures remain independently polled; renewal cannot prevent a handler holding the parent lock from committing. - **Step-by-step testing:** `run --next-step` executes one handler, commits its transition, and exits with the successor pending. Repeat the same command to advance again; the final step completes the request. The former `--max-stages` and `--pause-after-handler` flags are removed. - **Failure:** the handler saves the current row's error and a 30-second retry deadline. The transition returns `WaitUntil`; the worker exits and releases its lease. A later invocation retries the same row. No background scheduler or automatic retry daemon is added. The user workflow definition in `buzz-deletion/src/user/workflow.rs` declares allowed destinations and a decision function per stage. `gate_user` enters the first uncovered community. `purge_db` reads saved `has_agents`: true selects `purge_agents`; false completes the community immediately. Community completion selects the next uncovered community, or finishes the request when all are covered. No full stage plan is created upfront. The transition transaction contains no stage-name comparisons or fixed community count. Stage metadata stores `inputs`, `result`, `transition`, and `previous_stage_id`. The parent retains inventory, ownership, retry, and overall status. Approval evidence stays in `entity_deletion_approvals`. A completed-current row bridges the two transactions; real handlers will still need idempotent or reconciled actions if a process dies before saving its result. ### Code organization `buzz-deletion/src/user/worker.rs` runs the loop and heartbeat. Sibling `handlers.rs` executes dummy actions. `transition.rs` defines `UserDeletionTransition.get_next_stage()`, and `workflow.rs` owns the user stage rules and community-progress reconstruction. The CLI remains in `user.rs`. `buzz-db/src/store/entity_deletion/` contains shared workflow persistence: a small `mod.rs`, request reads/inspection in `requests.rs`, approval evidence in `approvals.rs`, ownership in `leases.rs`, and stage outcomes/atomic transitions in `stages.rs`. User-specific submission, demo inventory, and inventory validation live separately in `buzz-db/src/store/user_deletion/{requests,inventory}.rs`; its `mod.rs` only defines and exports the store. The worker calls the user transition object, which supplies a synchronous decision function to `EntityDeletionStore.transition_stage`. The store locks the parent, reads saved state, invokes that function, checks the returned operation, and commits its writes. The decision function performs no SQL or external calls. Reading, deciding, and writing remain in one transaction; there is no stale-state gap. Shared storage contains no user stage names or community-routing rules. User-specific approval validation also runs inside the shared approval transaction. This reorganization changes no tables, migrations, stage metadata, or CLI behavior. Requests using the existing saved-result format continue to work. `--next-step` still runs one handler and commits its transition before returning. ### Testing The walkthrough in [docs/operator-user-deletion-executor.md](https://github.com/block/buzz/blob/rarora/user-deletion-approval/docs/operator-user-deletion-executor.md) includes commands, SQL inspection, expected rows, and recovery boundaries. Submitted and approved a fresh local request and verified zero stage rows. Ran `run --next-step` five times. Each call completed exactly one handler, released ownership, and left its successor pending: B DB, B agents, C DB, C agents, then request completed. A sixth call left saved state unchanged. Verified both removed flags are rejected. Ran `--demo-no-agents-in 00000000-0000-0000-0000-00000000000c` and verified four completed rows, with no C agents stage. Injected a DB-stage failure, verified immediate retry refusal, waited for the real deadline, and resumed the same stage row. Observed heartbeat renewal and rejection of a competing worker, killed the owned worker process, waited for its actual lease expiry, and resumed the same unfinished stage with a new generation. Re-running a completed request left its saved state unchanged. Repeated the CLI walkthrough after the file reorganization, including runtime branching and a retry after the real deadline; a completed request created before the reorganization remained unchanged. Mutation-tested the ownership and recovery guards against local PostgreSQL 17. Reclaiming with the same executor ID rejects old-generation operations. Independently disabling the ownership generation check, release generation check, saved-transition/result comparison, or heartbeat-failure handling made the corresponding test fail. Restored all four protections afterward. The heartbeat test takes over the request while its handler is already running. ### Schema and rollout Unmerged migrations 0069–0070 add inventory and execution fields, widen request lifecycle states, and create operator-global approval and stage-history tables. They set five-second lock and thirty-second statement timeouts; constraint validation has its own transaction. No triggers, functions, foreign keys, or data backfills are added. Desired-state and migration catalog parity cover all three tables. The transition redesign adds no further schema changes. The serving relay does not schedule these requests. Only the explicit operator CLI runs them, using PostgreSQL. Only `demo:` targets are accepted. Real account discovery, user-write fencing, owned-community handling, and actual deletion remain future work. Verify staging with a new demo label and the documented commands. Older draft requests do not have the new stage metadata contract. Preserve them and create a new demo request for this version; they are not a supported resume format. Use a fresh database if an earlier draft applied a different migration checksum. Never alter sqlx migration checksums. With Helm `migrate.autoMigrate=true` (the chart default), a relay binary that lacks 0069/0070 fails at boot with sqlx `VersionMissing` after those migrations are applied. Recovery for this rollout is a roll-forward: deploy a corrected binary that retains the migrations. Do not delete migration records or change checksums to force an older binary to boot. Rolling back with auto-migration disabled requires a separately verified schema-compatibility plan. Demo requests, stage history, and approvals are intentionally retained; this scaffold has no cleanup command or retention job. Recheck migration numbering before merge.

fix(mesh): expire dead peer records and instrument mesh boot (#8503)
## Summary
Relay pods can stall in the `mesh_boot` startup step, and the mesh peer
table grows without limit. One prod pod held 7,793 peer records. Most of
those records belong to pods that no longer exist.
**Cause.** Every boot gets a fresh runtime id, so a restarted pod leaves
its old record behind. Nothing ever removed records, and scuttlebutt
gossip kept spreading the dead ones around the fleet. Each reconcile
pass, including the first one inside `boot_mesh`, then dials every
record one at a time.
This PR makes dead records expire. It also adds the measurements we need
to see the next stall directly.
### Peer-table lifetime (`crates/buzz-relay-mesh/src/membership.rs`)
- A peer record expires 5 minutes after its last heartbeat
(`DEFAULT_PEER_RECORD_TTL`). For comparison, live runtimes refresh every
2s, and the Redis ready registry expires a silent runtime after 45s.
- What happens to expired records:
- They are **rejected on arrival**, so peers that haven't been upgraded
can't re-add them.
- They are **left out** of digests, deltas, and dial candidates.
- They are **pruned** at the start of each reconcile pass.
- Between prunes, they are not admitted (`has_peer`) and not routed
(`peers`, `peer_has_capability`).
- An expired entry that hasn't been pruned yet counts as absent, so any
fresh record replaces it whatever its version. That lets a live peer's
v1 Redis hint re-admit it before the next prune.
- **The TTL never prunes or hides a peer with a live connection**, even
if its heartbeat is stale. Its gossip can stop arriving while the
transport stays up: a dead control stream, or a clock behind by more
than the TTL. The connection proves the runtime is alive. Its stale
record is still kept out of digests and dials. (The existing phi filter
in `peers()` still drops a connected peer once its gossip stalls; this
PR doesn't change that.)
- **`Connected` tracks the transport map.** Because the TTL exemption
trusts that flag, `install_peer` and `remove_peer` write it while
holding the peers lock, so a connection that closes during install
always ends `Disconnected`. A dial's `Connecting`/`Disconnected` writes
are skipped when a connection is already installed, so a failed outbound
dial can't overwrite a live inbound connection. Each reconcile pass also
re-syncs the state from the transport map.
- **Gossip no longer sets connection state.** Before, any gossiped
record was marked `Connected`, even if this pod had never dialed it.
That inflated the `/_mesh` counts. Now a record learned from gossip or
the ready registry enters as `Disconnected`. Only the real connect and
disconnect paths change the state.
- Before building its candidate list, reconcile now skips peers that are
already connected. A pass dials serially, and a dial to a dead runtime
can take about a minute, so `dial_peer` re-reads the record before every
address attempt. It stops once the record has expired or started
draining, or once a connection has landed.
### Instrumentation
- **`mesh_boot` sub-steps** use the existing startup-step gauges:
`mesh_bind`, `mesh_publish`, and `mesh_initial_reconcile`. A pod stuck
in `mesh_boot` now also shows which await it is stuck on.
- **New metrics** (`crates/buzz-relay-mesh/src/telemetry.rs`):
| Metric | Shows |
|---|---|
| `buzz_mesh_dial_total{outcome}` / `buzz_mesh_dial_duration_seconds` |
Cost of each dial |
| `buzz_mesh_reconcile_pass_seconds` | Full pass time |
| `buzz_mesh_reconcile_candidates` | Dials planned for this pass (set
after the registry scan) |
| `buzz_mesh_peer_records{state,draining}` | Table size |
| `buzz_mesh_peer_record_max_age_seconds` | Oldest heartbeat |
| `buzz_mesh_peer_records_expired_total{reason=pruned\|rejected}` |
Expiry activity |
- The dial and pass histograms get buckets up to 600s. The default
`_seconds` buckets stop at 5s, which would hide exactly the stall these
metrics are meant to show.
### CI
The `buzz-relay-mesh` tests and the `buzz-relay` `mesh_boot::tests` did
not run in any CI lane. This PR adds both to `just test-unit`, and adds
the matching stanzas to `scripts/run-tests.sh`.
### What got simpler
- The peer table now has a defined size, about one record per live pod,
where before it grew forever.
- One wrong state write was deleted (gossip marking records
`Connected`).
- Two test suites that silently never ran now run.
### Rollout notes
- Rejecting expired records works one pod at a time. During a rollout,
pods that haven't been upgraded keep gossiping dead records. Upgraded
pods reject them, which shows up as `reason="rejected"` on the expired
counter.
- A pod whose clock runs more than 5 minutes behind has all of its
gossip rejected. It stays reachable through its Redis ready record and
any live connection. A `reason="rejected"` count that keeps climbing
outside a rollout points to that skew.
- Upgraded pods leave expired records out of their digests. Pods that
haven't been upgraded therefore resend the whole ghost set (about 7.8k
records, roughly 1 MB) on every 2s gossip tick, on each old↔new
connection. So during the rollout, `reason="rejected"` will climb by
about the ghost count per tick per connection. This is expected and
stops when the rollout finishes.
### Not in this PR
The boot dial itself is still unbounded: it runs serially, has no
per-dial timeout, and dials gossip-learned records. Bounding it changes
how a pod joins the mesh, so it goes in a separate PR, and these metrics
will measure it.
### Related issue
None found.
### Testing
- New tests:
- `membership::tests`: expired gossip is rejected; prune drops only
expired records; prune keeps a connected peer with a stale heartbeat;
expired unconnected records are neither admitted nor routed before a
prune; a fresh record replaces an expired, unpruned entry whatever its
version; expired records are neither dialed nor gossiped before a prune;
gossip never sets connection state; table stats.
- `runtime::tests::reconcile_pass_publishes_dial_and_peer_table_metrics`
- `runtime::tests::reconcile_pass_prunes_expired_peer_records` (binds
the prune to the reconcile pass)
-
`runtime::tests::dial_skips_candidate_that_expired_after_the_pass_snapshot`
-
`runtime::tests::finishing_dial_does_not_overwrite_a_connection_that_landed`
-
`runtime::tests::connection_closed_during_install_ends_disconnected_and_expires`
-
`runtime::tests::reconcile_pass_resyncs_connection_state_from_transport`
- `mesh_boot::tests::mesh_boot_sub_steps_name_the_step_that_failed`
- Blox at `e06f55a4` (tree `866add1c`): `just fmt-check`, `just clippy`,
`buzz-relay-mesh` nextest 3x, and the `buzz-relay`
`mesh_boot`/`startup_steps`/`metrics` tests all pass. Three of the new
tests fail against a mutant that removes the fix they pin (dial ignores
expiry; dial state writes ignore the transport map; no reconcile
resync).

fix(deps): bump p256 to 0.14 for RUSTSEC-2026-0387 (#8592)
## Summary RustSec published [RUSTSEC-2026-0387](https://rustsec.org/advisories/RUSTSEC-2026-0387) against `crypto-bigint`. Some of its operations meant to be constant-time could compile to code that branches on secret values. Since the advisory came out, `cargo-deny check` reports advisories as failed. That breaks `Security Domain / Security` on `main` and on every PR that runs the Rust security job (for example #8575 and #8579). `crypto-bigint` 0.5.5 came in only through `p256` 0.13 → `elliptic-curve` 0.13 in `buzz-push-gateway`. The advisory has no 0.5.x fix; the patched line is 0.7.6+. This PR moves `buzz-push-gateway` to `p256` 0.14, which uses `crypto-bigint` 0.7.9. | Advisory | Crate | Change | |---|---|---| | [RUSTSEC-2026-0387](https://rustsec.org/advisories/RUSTSEC-2026-0387) | `crypto-bigint` | 0.5.5 → 0.7.9 (via `p256` 0.13.2 → 0.14.0) | **Code changes:** `p256` 0.14 renamed the SEC1 encoder from `ToEncodedPoint::to_encoded_point` to `ToSec1Point::to_sec1_point`. The gateway calls it in two places, both to re-encode an App Attest public key as uncompressed SEC1 bytes. The tests call it in five more. Nothing else in the gateway's API use changed. **Lockfile:** only the `p256` dependency chain changes: `ecdsa`, `elliptic-curve`, `ff`, `group`, `primeorder`, `rfc6979` and `sec1` move up a minor version. `primefield` and `wnaf` are added. The old `der`/`spki`/`pkcs8`/`pem-rfc7468`/`const-oid` 0.x versions that only this chain used are removed. `desktop/src-tauri/Cargo.lock` and the `buzz-feature-flags` fixture lockfile don't contain `crypto-bigint`, so they're unchanged. **Exposure, for context:** in production the gateway uses `p256` only to verify App Attest signatures against public keys. Signing with a private key happens only in tests. So the timing issue didn't realistically apply here, but the bump clears the advisory instead of ignoring it. ### Related issue N/A. I searched open and closed PRs for `RUSTSEC-2026-0387` and `crypto-bigint` and found none. ### Testing - `cargo-deny check`: `advisories ok, bans ok, licenses ok, sources ok`.

fix(deps): bump ctutils to 0.4.5 for RUSTSEC-2026-0385 (#8560)
🤖 ## Summary On 2026-10-23, RustSec published RUSTSEC-2026-0385 against `ctutils`, a constant-time helper crate used by the RustCrypto hashing and HMAC crates. Some of its functions were meant to run in constant time, so their timing would reveal nothing about secret values, but in versions before 0.4.4 they could compile to code that branches on those values. Since the advisory came out, `cargo-deny check` reports advisories as failed. That breaks `Security Domain / Security` on `main` and on every PR that runs the Rust security job. This PR changes `ctutils` from 0.4.2 to 0.4.5 in the three lockfiles that pin it: `Cargo.lock`, `desktop/src-tauri/Cargo.lock`, and the `buzz-feature-flags` relay-feature-selection test fixture. No other packages change. | Advisory | Crate | Change | |---|---|---| | [RUSTSEC-2026-0385](https://rustsec.org/advisories/RUSTSEC-2026-0385) | `ctutils` (non-constant-time mask generation and `u128` comparisons) | 0.4.2 → 0.4.5 | ### Related issue N/A. I searched open and closed PRs for `ctutils` and `RUSTSEC-2026-0385` and found none. ### Testing - `cargo deny check advisories`: `advisories ok`. On `origin/main` the Security job fails on this advisory. - `cargo check --workspace` passes. - `cargo test -p buzz-feature-flags --test relay_feature_selection_contract` passes.

docs(cli): drop private references from the agent format comment (#8508)
### Why? #8234 merged before its last review fix landed, so the `agent_event` doc comment on main names a private repository and its internal class. Public code should not reference private implementations. ### What? Keeps the public pointer to buzz-app's MCP formatter and replaces the private one with a generic note that other agent read surfaces trim the same fields.

fix(db): rebuild events_pkey in declared order after pgschema apply (#8525)
## Summary Re-applying `schema/schema.sql` to a database that `pgschema apply` and `scripts/reconcile-schema-after-pgschema.sql` already bootstrapped fails with `cannot drop inherited constraint "events_p2026_01_pkey" of relation "events_p2026_01" (SQLSTATE 42P16)`. Because of that, `scripts/start-relay-for-tests.sh` breaks against a reused database. **Cause:** pgschema 1.7.4 moves a partitioned table's partition key to the front of its primary key when it creates the table. A pgschema-bootstrapped `events` therefore gets `PRIMARY KEY (created_at, community_id, id)`. `schema/tables/public/events.sql` and `migrations/0001` both declare `(community_id, created_at, id)`. Every later plan drops and re-adds `events_pkey` and each declared child's key. This happens even on a database that was never reconciled. The plan only becomes unexecutable after the reconcile script attaches the children, because their keys are then inherited. As a side effect, pgschema-bootstrapped databases also had a differently ordered PK index than migration-managed ones. **Fix:** after the partition ATTACH block, the reconcile script now compares `events_pkey` with the declared `PRIMARY KEY (community_id, created_at, id)`. If they differ, it rebuilds the key on the parent. It then asserts that `events` and every partition carry the declared key, which is the "convergence plus live assertion" shape `docs/database.md` requires. PostgreSQL recreates each partition's key with the same `<child>_pkey` names, so a reconciled re-apply now plans nothing. The block does nothing when the key is already correct. `migrations/0001` is untouched. Only pgschema-bootstrapped dev and test databases run this script, so it does not touch the out-of-band partitioned-table procedure. `delivery_log` is not affected. Its key `(delivered_at, id)` already starts with the partition key. **Existing local databases:** a database reconciled before this change would still fail its next `pgschema apply`, because the reconcile script only runs after apply. The repair therefore also lives in `scripts/repair-events-pkey.sql`. That file does nothing when `events` doesn't exist yet, and `scripts/start-relay-for-tests.sh` runs it before apply; it's the only launcher that reuses its database. The reconcile script keeps a verbatim copy for fresh bootstraps, and a unit test keeps the two identical. The rebuild drops the key with `IF EXISTS`, so a database that has lost its key still converges. It also takes its locks with a 10s `lock_timeout`. If a relay still holds `events`, it fails with "Stop any relay using this database, then rerun" instead of hanging. `start-relay-for-tests.sh` now builds the relay's `DATABASE_URL` from the `PG*` variables it already exports. The secret scanner flags the literal URI once the file is touched. The value is unchanged. pgschema 1.13.3 keeps the declared order and creates children as native `PARTITION OF`. Upgrading would make this block and the ATTACH blocks unnecessary, but it changes behavior for every caller, so it is left for a separate change. ### Related issue Follow-up to block/buzz#8487, which added the probe test and `.pgschemaignore`. Now rebased onto `main` after that PR merged. ### Testing - `pgschema_reapply_keeps_runtime_partitions` now asserts the plan after the maintenance pass is **empty**, which replaces the `DROP TABLE` and per-monthly plan checks. It then applies and reconciles a second time. Without the new block it fails with `ALTER TABLE events DROP CONSTRAINT events_pkey; ...`. With the block it passes. - It also includes the optional notes from the #8487 review: - After maintenance, it checks that both catch-alls are still present and attached, not only that the zipped bounds differ. - The first runtime monthly comes from the declared catch-all's lower bound instead of a hard-coded `p2026_07`. - The doc comment now states only what the test pins: bounds are not compared, and the plan is empty. - I broke the rebuild on purpose by re-adding the key in the wrong order. The new assertion fails the reconcile script with `events and its partitions must have PRIMARY KEY (community_id, created_at, id)`. - CLI runs against local Postgres 17: - Fresh DB: apply → reconcile → apply → reconcile → plan. The second apply reports no changes and the plan is empty. - DB reconciled with the old script: the next apply fails with SQLSTATE 42P16. After running the new reconcile script once, apply reports no changes and the plan is empty. - `events_pkey_repair_runs_before_reused_apply_and_matches_reconcile` checks two things: the reconcile script carries the repair block verbatim, and `start-relay-for-tests.sh` runs the repair before `pgschema apply`. It fails if the two copies drift. - I ran the repair script and then the bootstrap against four local probe databases: one reconciled with main's script, an empty one, one applied but never reconciled, and one with no `events` key. All four end with an empty plan. With another session holding a lock on `events`, the repair fails after 10s with the hint and leaves the key untouched. It succeeds once the lock is released. - `admin_schema_parity_between_desired_state_and_migrations` and the `runtime::migration` unit tests pass. fmt and clippy are clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Ian Oberst <ioberst@block.xyz> Co-authored-by: Ian Oberst <ioberst@block.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

BUZZ-301: Add user deletion request intake (#8496)
## Summary
Add the first testable piece of user deletion: submit a synthetic
request, list requests, and inspect one by UUID. Operators can verify
that intake reaches PostgreSQL before we add inventory, approval, and
execution.
Add one operator-global `entity_deletion_requests` table with an
additive migration and matching desired-state schema. Identical
submissions return the same row. Conflicting submissions fail without
changing it. Only `demo:` targets are accepted, and requests stay
`submitted`.
Keep the commands in `buzz-deletion`, reached through a thin `buzz-admin
user-deletions` adapter. Reuse the existing database connection setup.
This change adds no worker, stage history, community gates, or deletion
operations.
### Rollout plan
This is an expand-only schema change plus an operator CLI. Existing
relay code does not use the new request table. No backfill or real
deletion is part of this release.
1. **Order the PRs.** Land #8496 first, using 0068; main now owns 0067
for channel join roles. Rework #8489 to build on this table with the
next available migration number. Renumbering its existing CREATE TABLE
migration alone is insufficient; both PRs currently create the same
request table.
2. **Apply on staging.** For deployments that manage schema separately,
apply the reviewed additive migration before using the new CLI. Where
auto-migration is enabled, the new relay binary applies it at startup.
Keep existing tables and records unchanged.
3. **Verify on staging.** Use the new `buzz-admin` binary with
`DATABASE_URL` pointing to staging. Submit a unique synthetic label,
list requests, and inspect the returned UUID:
```bash
buzz-admin user-deletions submit --target demo:staging-intake-1
--requested-by <operator>
buzz-admin user-deletions list --limit 5
buzz-admin user-deletions inspect <returned-uuid>
```
Verify one `entity_deletion_requests` row with status `submitted`.
Repeat the identical submission and verify the same UUID and timestamps.
Use a new label if this label was used by an earlier staging test.
4. **Apply beyond staging.** After verification, use the deployment's
reviewed schema/release workflow to add the table in the remaining
environments. Requests run only through the operator CLI; this release
starts no deletion worker. No feature flag is needed for this synthetic
intake: the database accepts only `demo:` targets, and real deletion is
absent.
5. **Rollback.** Keep the additive table and saved requests; stop using
the new commands and roll back the binary if needed. After 0068 is
applied, an older binary with auto-migration enabled can fail at startup
with sqlx `VersionMissing`. A binary rollback therefore requires
migration execution to be disabled on the older relay
(`BUZZ_AUTO_MIGRATE=false`, including the corresponding deployment
configuration).
### Related work
This is a smaller first slice of the full-workflow draft
[#8489](https://github.com/block/buzz/pull/8489), which is preserved for
later extraction. The two PRs overlap and should not both be merged as
written.
### Testing
The author submitted `demo:rarora-manual-1` to a separate local
PostgreSQL 17 database. Repeating the same submission returned its
original UUID and timestamps. List, inspect, and a direct SQL query all
returned the same saved request.

fix(relay): apply channel setting changes atomically and lock every membership writer (#8516)
🤖 ## Summary This PR fixes two ways the relay could report a channel change that did not fully happen. **1. Channel settings could be saved only in part, while the app was told that they all worked.** When an owner or admin changed a channel's settings (name, description, topic, public or private, message lifetime, archived or not, who can join), the relay saved the request first and then applied each setting with its own database write. If one write failed, the relay only logged the error. It skipped the remaining settings and still reported success. Sending the request again did nothing, because the relay saw it as already saved. Example: a switch from public to private could fail while the app showed success, and the channel stayed public. Now saving the request, applying every setting and saving the "settings changed" messages in the channel happen in one database transaction. Either all of it is saved or none of it is: - If anything fails, nothing is saved and the client gets an error. It can send the same request again. - A repeat of a request that already succeeded is reported as a duplicate and changes nothing. This is also true when the repeat arrives while the first copy is still being saved. - A request to restore a channel that is not archived, or to change an archived channel without restoring it, is refused and nothing is saved. Before, the relay saved the request and a "settings changed" message, and then the restore failed. - Live updates go out only after the save commits. These are: removing access for people who lose it, and pushing the new messages and channel info to clients. **2. A published member list could include someone who had just been removed.** For some channels the relay publishes a list of the channel's members. While it builds that list, it holds a per-channel membership lock. Kicks by a relay admin and the automatic kick after a deploy did not take that lock. A kick could commit after the list was read, so the published list still showed the removed member. Channel deletion also did not wait for the lock. Kicks, channel deletion and the automatic add when someone joins a Huddle (voice call) now all take the lock first. The published list then includes the change, or the change waits until the list is saved. ## Details - **One lock order for all channel settings writes.** Before, each writer took its own locks. Review kept finding writers that took them in a different order or forgot one. `lock_channel_for_settings_write` (`crates/buzz-db/src/store/channel.rs`) is now the only place that takes them. The order is: 1. the membership lock, only when the public/private setting or the "who can join" setting (`join_role`) changes. Without it, a member add could read the old rule while the change commits. 2. the message-lifetime (TTL) lock: exclusive for a lifetime change, shared otherwise. 3. the channel row (`FOR NO KEY UPDATE`). This does not block the key lock that a member insert takes. The row lock also orders two copies of the same request, so the second copy sees the first as already stored. - The function returns a `ChannelSettingsWriter`. The writer borrows the transaction that took the locks, so the compiler stops it from being used with another transaction or after commit. The settings writes (`update_channel_on`, `set_topic_on`, `set_purpose_on`, `set_archived_on`) require the writer. They refuse a change its locks do not cover. - `Db::apply_channel_metadata_event` stores the channel-edit event (kind:9002) and its mentions, applies the settings and stores the "settings changed" messages (kind:40099) in one transaction. The older single-purpose writes (`update_channel`, `set_topic`, `set_purpose`, `archive_channel`, `unarchive_channel`) use the same helpers and behave as before. - `ingest.rs` and `validate_admin_event`: channel edits no longer check archived/active state before the write. The transaction checks it after its duplicate check, under the row lock. A refusal there goes back to the client as `invalid:`. Channel edits have their own save path and skip the general post-save step. `handle_side_effects` refuses them, so no caller can go around the transaction. - `side_effects.rs`: `emit_system_message` is split into signing and sending. The messages are signed before the transaction and sent after it. All "settings changed" messages from one edit share one timestamp and come in a fixed order (topic, purpose, visibility, lifetime, archive). - A change to "who can join" (`join_role`) is applied in the same transaction and announced with its own `join_role_changed` message. - **Membership lock outside settings** (`relay_admin_actions.rs`, `channel_members.rs`, `audio/handler.rs`): both kick paths (`execute_kick_with_marker`, `deploy_kick_member`) take the membership lock before they remove the member. The marker kick still undoes the removal if its lease check fails after waiting. The Huddle join takes its locks through a new `ChannelMembershipLocks` token, and the auto-add is a method on that token, so it cannot run without the lock. `soft_delete_channel` takes the full settings lock order. - **Limit of the membership lock:** it covers member changes, public/private and "who can join" changes, and channel deletion. It does not cover archiving: archive writes and the cleanup of expired temporary channels do not take it. The cleanup keeps its single UPDATE. A comment in `channel.rs` explains why that is safe and why it must not be split into a read and a write. ### Related issue Follow-up to the review of #8143 (which added the "who can join" setting). That review found that channel edits could be applied in part. No separate issue. ### Testing New PostgreSQL tests in `crates/buzz-relay/src/handlers/edit_metadata_postgres_tests.rs`: - `failed_edit_stores_nothing`: a test trigger makes one write fail partway through the transaction. Nothing is stored or changed, on the first send or a resend. Without the trigger, the same signed request applies in full. - `resent_edit_is_a_duplicate`, `resent_archive_and_unarchive_are_duplicates`: a resend after success is a duplicate and adds nothing. - `resend_validated_after_the_first_commit_is_a_duplicate`: a resend validated after its first copy committed is a duplicate, with no second change and no second message. - `concurrent_copies_of_a_restore_apply_once`: two copies of one restore, held at the channel lock until both are waiting, apply once. The other copy is a duplicate. - `unarchive_of_an_active_channel_is_refused`, `join_role_edit_is_applied_and_announced`. Lock tests in buzz-db: each one holds a member list in progress and checks that the writer waits for it. They cover a "who can join" change (`channel_members.rs`), the deploy kick and the marker kick (`relay_admin_actions.rs`), and channel deletion (`channel.rs`). The kick and delete tests fail when the new locks are removed. These tests and the existing channel-edit tests in `group_state_postgres_tests` pass locally against a migrated PostgreSQL database. --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Co-authored-by: Larry <627498bd4bd1f281a16431e3c6cce3b5c25b6692798c78672298aefbf2f8f8b5@buzz.block.builderlab.xyz> |

fix(db): keep pgschema re-apply from dropping runtime partitions (#8487)
## Summary pgschema doesn't compare partition bounds. Re-applying `schema/schema.sql` to a database a relay has used therefore plans `DROP TABLE IF EXISTS ... CASCADE` for every `events` / `delivery_log` monthly the partition manager created at runtime, and those tables' rows are deleted with them. Since #8464 the manager advances the catch-all by default, so any local dev or test database a relay has started against now hits this. One example is the persistent `buzz` database that `scripts/start-relay-for-tests.sh` re-applies. This adds a root `.pgschemaignore` that hides dated monthlies (`events_p2*`, `delivery_log_p2*`) from pgschema. The monthlies declared in `schema/partitions/` are exempted with `!` patterns, so pgschema still manages them. pgschema reads the file from its working directory, and every caller already runs it from the repo root: the test-relay launchers, `postgres-test-setup.sh`, the desktop release smoke and `_ci-relay.yml`. Both partition files now carry a note pointing at it, and AGENTS.md gotcha #7 adds "run pgschema from the repo root" next to the reconcile rule. New-install layout is unchanged. **Why the drops haven't deleted data yet:** on a reconciled database a re-apply also plans to drop and re-add the `events` primary key on the parent and on each declared child. The apply then fails with `cannot drop inherited constraint "events_p2026_01_pkey"` (42P16). That happens with or without this PR. The planned drops run in the same single transaction, so they roll back, and the runtime monthlies have survived so far. Once that primary-key drift is fixed, re-applies will succeed and this ignore file is what keeps them from dropping the runtime monthlies. The primary-key fix is a separate follow-up. ### Related issue Follow-up to #8464. Salvaged from an earlier branch; no existing issue found. ### Testing - `pgschema_reapply_keeps_runtime_partitions` (Postgres) follows the real bootstrap path in a dedicated database: - `bin/pgschema apply` from the repo root, then `scripts/reconcile-schema-after-pgschema.sql`; - the relay's default maintenance pass (create plus advance); - asserts that both catch-alls were attached before the pass and that their bounds moved after it; - asserts that each parent's `p2026_07` monthly exists. The catch-all advanced past the declared bounds but kept its name. - asserts that `pgschema plan` contains no `DROP TABLE` and no line mentioning any runtime monthly. - Falsified both ways: - With `.pgschemaignore` removed, the test fails and prints the planned drops. - Without the reconcile step, it fails with `reconcile did not attach both catch-alls`. - `pgschemaignore_exempts_exactly_the_declared_monthlies` checks that the `!` exemptions exactly match the dated monthlies in `schema/partitions/`. - The admin parity test now shares the `pgschema` helper, so it also runs from the repo root like the real callers. - All `runtime::migration` and `store::partition` tests pass against local Postgres after merging current main, including the ignored ones: 104 passed, run with `--test-threads=1` because the full nextest Postgres lane needs local `dropdb`. `clippy -D warnings` and the pre-push lanes pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Ian Oberst <ioberst@block.xyz> Co-authored-by: Ian Oberst <ioberst@block.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

fix(db): bound every statement and the #p mention scan (#8461)
## Problem An agent `#p` + `#h` + `since` REQ (the `require_mention` subscription in `buzz-acp`) ran for over 45 minutes on a production writer and held `AccessShare` on every `events` partition. There were two causes: 1. **The mention side of the `#p` join was unbounded.** `build_query_events_sql` joined `event_mentions` on `(community_id, event_id)` only. The planner picked a nested loop whose outer side was every mention of the pubkey, ever, and whose inner side range-scanned the channel index from `since` on each partition. Cost ≈ total mentions × channel rows since `since`. 2. **Nothing cancelled it.** The writer `statement_timeout` defaulted to `0`. Only `#e` reads had a deadline (the 20s cap from #7854), and read-replica sessions had none at all. `pg_stat_statements` shows this shape has a multi-thousand-second max going back months, so it is chronic and was not introduced by a recent change. ## Change **`#p` mention bound** (`store/event.rs`, `push_mention_join`, shared by the page SELECT and COUNT) - Join on the full event key, `AND e.created_at = m.event_created_at`. Mention rows copy the event's `created_at` at insert (migration 0007 already relies on this equality), so the join can prune `events` partitions by time. - Repeat `since`/`until` on `m.event_created_at`, so the outer scan is a range on the existing `idx_event_mentions_pubkey_created`. `until` is a superset bound for the keyset cursor; the exact `(created_at, id)` cursor test stays on `e`. - Repeat `kinds` on `m.event_kind` when the filter has kinds. Every production mention writer binds the event kind (`insert_mentions` in `store/runtime/mod.rs`, and the replaceable-event path in `store/replaceable.rs`, back to the first Postgres schema), and no migration inserts mention rows, so this drops no rows written by the relay. Rows imported out of band with a NULL `event_kind` would no longer match a kinds-filtered `#p` read; a read-only production count on 2026-10-20 found 0 such rows on both production reader databases. The pushdown makes `idx_event_mentions_pubkey_kind_created` available to the planner for the `require_mention` kind-9 shape; its use has not been observed (see below). An E2E fixture with a hand-set NULL `event_kind` row confirmed the caveat: base returns 8 events, head 7. - The feed's mentions and needs-action queries (`store/feed.rs`, `build_mentions_query` / `build_needs_action_query`) join `event_mentions` the same way, so each joined row probes one `events` partition instead of all of them. Their `ORDER BY m.event_created_at ... LIMIT` already kept them from running away; this removes the per-row cross-partition probe. - Observed plan (E2E at `9cb6638b1`, before the `kinds` pushdown; 60,000 historical mentions + 2,500 recent decoys, stock planner, `EXPLAIN (ANALYZE, BUFFERS)` of the captured production SQL): the mention side is a bounded range on `idx_event_mentions_pubkey_created` (13 rows), then a hash join with a scan of the recent `events` partition. Base scanned 2,509 recent events and probed `event_mentions_pkey` 2,509 times. Head: **1.1 ms / 319 shared hits**; base: **8.5 ms / 10,049 shared hits**. Not measured against the production replica. A fresh `EXPLAIN (ANALYZE, BUFFERS)` replay at `a7065c367`, after the pushdown, ran on a smaller fixture where the planner chose a sequential mention scan, so it neither confirms nor replaces these numbers. **Reads: 20s deadline on every generic event read** - `query_events_on` and `count_events_on` always run under the transaction-local 20s deadline that `#e` reads used (`fetch_with_read_deadline`, formerly `fetch_with_e_tag_deadline`). It only tightens: shorter operator or caller caps are kept. - Read-replica sessions get a 20s session default through `after_connect`, using the same tighten-only SQL. - Cost: every generic REQ history read and COUNT now pays BEGIN + `set_config` + ROLLBACK (three extra round trips; before, only `#e` reads did). In the local E2E the end-to-end history read was still faster at head (median 4.1 ms vs 10.2 ms at base, 9 samples each, warm cache), so the round trips are dominated by the bounded plan; this does not isolate them or establish production p99. The round trips also lengthen how long each such read holds its writer connection; that hold time has not been measured against production pool sizing. - A replica read cancelled at its deadline (57014) is returned, not re-run on the writer. Usually the cancel means expensive work the writer would only repeat. It can also mean the replica waited on a lock only it holds (a replayed `ACCESS EXCLUSIVE` from primary DDL), when the writer would have answered quickly; that miss is the accepted price of keeping runaway reads off the primary. The rationale now lives once on `DbError::is_statement_cancelled` instead of in a dozen copied comments. The generic routed reads and `ReadSession` already did this; the eight routed reads with their own SQL (feed mentions, needs-action and activity; thread replies; channel window; relay membership; thread window and its auxiliary scan) now do too. A cancelled auxiliary scan also keeps its replica session instead of degrading it to the writer for the rest of the request. Other replica failures (e.g. hot-standby recovery conflicts) still fall back to the writer. - Paths with their own tighter `SET LOCAL` (artifact 2–5s, thread window 4s, personal reads, usage 5–15s, serving lease 1.5s) are unchanged. **Writes: every writer session is bounded** - The default `statement_timeout` changes from `0` to 120s (`DEFAULT_STATEMENT_TIMEOUT_MS`). - `BUZZ_DB_STATEMENT_TIMEOUT_MS` still overrides it. `0` or any value above 300s installs 300s (`MAX_STATEMENT_TIMEOUT_MS`), so a session can no longer disable it, and a clamped value logs a `warn!` when the pool is built. Only the operator-approved, fenced destruction paths below lift it, per transaction. **Long-running writer paths, audited** | Path | Behavior | |---|---| | Migrations / schema destruction (`with_exclusive_schema_destruction_lock`) | Unchanged: these lift lock and statement timeouts on their own detached connection | | Partition maintenance | Unchanged: own 5s `statement_timeout` | | Partition audit (`buzz-admin`) | Unchanged: 30s | | Community deletion inventory, purge and logical verification (`inventory_schema` whole-tenant counts, `purge_postgres` whole-community `DELETE` per table in one tx, `verify_postgres_logically_deleted` whole-tenant `EXISTS` per table right after the purge) | Lifted (`statement_timeout = 0`) transaction-locally by `lift_statement_timeout`, like migrations; lock and idle timeouts still bound them. Inventory counts each table in its own lifted transaction, so each table's lock and snapshot are released as soon as its count finishes, as the autocommit counts did. A cancelled purge would retry from scratch and eventually block, so a cap here would turn large-tenant deletion into an operator override | | Audit appends (`buzz-audit`, audit pool inherits the writer cap) | Waits on the audit-chain advisory lock. With `BUZZ_DB_LOCK_TIMEOUT_MS=0` (or at least the statement cap), `statement_timeout` (57014) cancels the wait instead of `lock_timeout` (55P03). The relay's audit worker now retries both with the same backoff instead of dropping the entry on 57014; admission refusal stays terminal | On HTTP routes a statement timeout already maps to the distinct retryable 503 (`api/mod.rs`, `statement_timeout_maps_to_distinct_503`). A cancelled REQ fails its history read instead of hanging. ## Tests - `p_tag_query_bounds_mention_side_by_time` (unit): page and COUNT SQL carry the `created_at` join and the `since`/`until`/`kinds` mention bounds, and the bounds are absent when the filter has none. - `p_tag_read_with_mention_bounds_keeps_results` (Postgres): through the production mention insert, unbounded, `since`, window and keyset-cursor reads return exactly the mentioned rows, and COUNT matches. Every bound sits exactly on a mentioned row's second and the cursor page includes a same-second sibling after the cursor id, so an off-by-one on either mention-side bound fails it. - `plain_read_is_cancelled_at_deadline_when_timeout_disabled` / `count_events_cancels_at_read_deadline_when_timeout_disabled` (Postgres): the production `#p` + `#h` + `since` shape and a plain COUNT are cancelled at 20s with the session timeout disabled. Previously these covered `#e` only. - `writer_statement_timeout_is_always_bounded` (unit) and `session_statement_timeouts_bound_writer_and_reader_sessions` (Postgres): through `Db::new`, writer sessions install `2min` / `5min` (for `0` and for 600s) / `45s`, and replica sessions install `20s`. - `deletion_whole_tenant_stages_outlive_the_writer_statement_timeout` (Postgres): on a scratch desired-state database with a 500ms writer cap, the real `inventory_schema`, `purge_postgres` and `verify_postgres_logically_deleted` each wait behind a held `ACCESS EXCLUSIVE` lock on `events` for over 1s and still complete, a plain statement is cancelled (57014), and pooled sessions still read `500ms` afterwards. A lifted transaction reads `statement_timeout = 0`, so a bounded lift (e.g. `'300000'`) fails it, as does removing any of the three `lift_statement_timeout` calls. - `mentions_query_is_tenant_scoped_and_joins_mentions_by_composite_key` / `needs_action_query_is_tenant_scoped_and_joins_mentions_by_composite_key` (unit): both feed queries carry the `e.created_at = m.event_created_at` join. - `replica_statement_cancel_propagates_without_writer_rerun` (Postgres): with the replica locked past its cap, each of the six routed reads above returns 57014 instead of the writer's copy. Removing the cancel arm in any of them fails it. - `thread_window_statement_cancel_propagates_without_writer_rerun` (Postgres): a thread-window read parked behind a replica lock and cancelled (57014; the window's own 1s `lock_timeout` would otherwise fire first) returns the cancel instead of the unlocked writer's window, and an auxiliary scan timed out on a replica session returns 57014 and leaves the session on the replica. Removing either guard fails it. - `audit_worker_retries_statement_timeout_until_original_entry_is_appended_once` (Postgres, `buzz-relay`): the production audit worker, with `lock_timeout` disabled and a 100ms statement cap, keeps the entry through repeated 57014 cancels while the chain lock is held and appends it exactly once after release. Treating only 55P03 as retryable fails it. - The existing writer and audit-pool GUC tests now expect `5min` for a disabled statement timeout. ## After deploy, watch - `buzz_db_route_decision{decision="replica",reason="statement_cancelled"}`: replica reads that now fail instead of falling back to the writer, including the replica-only lock case above. - `buzz_db_pool_acquire_wait_seconds` and `buzz_db_pool_waiters` on the writer pool: every generic REQ history read and COUNT now holds its connection for three extra round trips. ## Database checklist (`docs/database.md` § Review checklist) This PR changes schema-dependent `buzz-db` queries (the `#p` join and its `m.event_kind` pushdown). It does not change the schema. - **Phase:** none. No schema change, so this is not an expand, backfill or contract step. Nothing before or after it is required. - **Triggers, functions, procedures, rules, foreign keys:** none added. - **Row mutations / backfill:** no migration, and no row is mutated or backfilled. The one data-shape dependency is mention rows with a NULL `event_kind`: a kinds-filtered `#p` read no longer matches them (see the `kinds` bullet under Change). Relay writers always bind `event_kind`, so only rows imported out of band are affected. A read-only production count on 2026-10-20 found 0 such rows on both production reader databases. - **Contract migration:** N/A. - **Rule 4 locations:** none touched. No table, index or desired-state file changes, so no parity test applies. The new bounds use the existing `idx_event_mentions_pubkey_created` and `idx_event_mentions_pubkey_kind_created`. - **Deployed relay vs. new schema:** there is no new schema. The currently deployed relay and this relay run against the same tables. - **Lock and statement timeouts:** this PR is about them. Generic reads get a 20s deadline, replica sessions a 20s default, and writer sessions a 120s default capped at 300s. Community-deletion transactions lift `statement_timeout` per transaction; migrations and schema destruction are unchanged (see "Long-running writer paths, audited"). No index builds and no operator prebuild step. ## What got simpler - One read-deadline path instead of an `#e`-only branch in `query_events_on` and `count_events_on`. - The `#p` join SQL that was duplicated between SELECT and COUNT now lives in one `push_mention_join`. - The deletion tests share one scratch desired-state database helper instead of an inline copy. - "Is this query bounded?" now has one answer: yes, unless it runs in a migration, schema destruction, or community-deletion transaction. ## Identified debt (not in this PR) - `buzz-acp` re-sends the same filter after a timeout `CLOSED` (no backoff or narrowing). With the `#p` bound the `require_mention` read should finish well inside 20s, so this is a follow-up, not a blocker. --------- Signed-off-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> |

feat(relay): add announce channels with a join_role setting (#8143)
🤖 ## Summary Channels are Buzz's main way to control access, but today they cannot separate reading from writing. In an open channel, anyone who can read can also write. So there is no way to say "many people read, a few people write". Announcements, release feeds, plugin release records and shared configuration all need that. This PR adds **announce channels**: anyone can follow and read them, but only members can post. It does this with one new channel setting and without changing what any role means. - **Roles mean the same thing in every channel.** A *guest* can read and leave, but cannot write. A *member* (or *bot*) can write. *Admins* and *owners* also manage the channel. The relay already had the guest role, but no client used it until now. - **A new setting, `join_role` (`member` | `guest`), picks the role a new person gets** when nobody chooses one: when they join by themselves, or when someone adds them without a role. The default, `member`, keeps today's behavior for every existing channel. - **An open channel with `join_role = guest` is an announce channel.** Anyone can find, read and join it. People who join are guests, so they cannot write until someone makes them a member. The relay enforces these rules, so a client cannot get around them. What each role can do (the same in every channel): | Action | Guest | Member or bot | Admin / owner | | --- | --- | --- | --- | | Read, leave | ✅ | ✅ | ✅ | | Post, reply, edit, delete own, react, artifacts, canvas, forum, pins, topic, typing, workflow messages, save or run workflows, huddles | ❌ | ✅ | ✅ | | Add people | ❌ | ✅ as member, guest or bot | ✅ any role | | Make a guest a member (person or agent) | ❌ | ✅ | ✅ | | Any other role change | ❌ | ❌ | ✅ | | Change name, about, visibility, TTL, `join_role` | ❌ | ❌ | ✅ | Other rules: - **Joining by yourself.** A person who joins (kind:9021), or adds themselves (kind:9000 with their own key), gets the channel's `join_role`. They may ask for `join_role` or a lower role, never a higher one. So in an announce channel nobody can join as a member by themselves. - **Non-members.** A non-member may write only where joining would let them write: an open channel with `join_role = member`. That is today's behavior for open channels. - **Agents.** Agents follow the same rules as people. Any member who can write may make a guest agent a member. Limits that only an agent's owner may lift belong to the later IFC work (its "restricted" agent level), not to this PR. That work only refuses more actions, so it can be added later without breaking anything here. - **Leaving always works.** A member may leave an archived channel too (kind:9022, or kind:9001 naming themselves). The last owner still cannot leave. - **Agent owners keep edit and delete.** Today the human owner of an agent can edit (kind:40003) and delete (kind:9005) that agent's messages without being a member. This PR keeps that existing behavior in announce channels too, and documents and tests it. It does not let the owner post. - **Changing the setting changes no roles.** Existing members can still write after a change to `guest`. Existing guests stay read-only after a change back to `member`. A refused write gets `restricted: only members can post in this channel`. ## Details - **One write rule.** The relay's channel write check decides from the actor's role and the channel's `join_role`. Some event types skip that check and run their own: message edit, deleting your own message (kind:9005), topic and purpose (kind:9002), add-member (kind:9000), workflow messages and joining a huddle. Each of these now uses the same rule. Membership changes (add, remove, leave) do not need write access, so a guest can always leave. If the relay finds a stored `join_role` value it does not know, it treats it as `guest`, so an unknown value can never give more access. - **Admission is decided in the database transaction.** The membership write (`put_member`) makes the whole admission decision inside its transaction, after it takes the channel's membership lock: `join_role` for a missing role tag, the self-join ceiling, guests cannot add people, who may grant admin or owner, and role changes (`MemberRole::may_change_role`). The relay's request check uses the same rules, but the database is the authority, so a write that skips the request check cannot get around them. A change to `visibility` or `join_role` takes the same lock, so an add and a setting change cannot interleave. - **No creator exception.** `put_member` used to give owner to a channel's creator who added themselves to a private channel without an active membership. A removed creator could use that: their join (kind:9021) passes the open-channel check, the channel becomes private before the join takes the membership lock, and the join restored them as owner. Channel creation already makes the creator owner in the same transaction, so the exception is removed. A removed creator is now admitted like anyone else. - **Huddles.** Joining a huddle needs write access in the huddle channel **and** in its parent channel. The relay checks both before the join. When it commits the join, it applies the same rule again while it holds both channels' membership locks: a member needs a role that can post, and a non-member needs an open channel whose `join_role` is `member`. A guest in either channel cannot join. A join is also refused when the joiner loses membership or the channel's `join_role` changes before the commit. - **One lock order.** Each writer that takes more than one of a channel's locks takes them in this order: membership lock, TTL lock, channel row. Settings changes, roster publication, TTL refresh and huddle joins all use this order. Before this change, a `join_role` change on an ephemeral channel at the same time as a roster publication could deadlock. - **Workflows.** Saving a workflow (kind:30620) skips the generic write check, so it now checks the sender's role itself and needs a writing role before anything is stored. Every path that starts a workflow run, including the manual trigger (kind:46020), needs the workflow's owner to hold a writing role now (and an elevated role for an elevated workflow). So a workflow saved while its owner was a member stops running after the owner is made a guest. - **Channel names are checked before storage.** kind:9002 and kind:9007 refuse a name longer than the `channels.name` column (255 characters) before the event is stored. Before this, the relay accepted the event, then the name update failed, and the rest of the update (for example `join_role`) was silently skipped. This PR only adds this check. Storing the event and applying the update in one transaction is a larger change, and it is not in this PR. - **Changing the setting.** Owners and admins send a channel-metadata update (kind:9002) with `["join_role", "guest"]` or `["join_role", "member"]`. Buzz applies these updates as partial updates; a missing tag means "no change". The relay posts a `join_role_changed` system message in the channel. - **What clients see.** The relay signs a channel description event (kind:39000) that clients read. One shared builder now writes it for both the relay and the `buzz-admin` backfill, which had a copy that had drifted from the relay's. It always publishes an explicit `["join_role", …]` tag, plus the standard NIP-29 group access flags: | `visibility` | `join_role` | `public` / `private` | `restricted` | `closed` | | --- | --- | --- | --- | --- | | open | `member` | public | | | | open | `guest` | public | ✓ | | | private | either | private | ✓ | ✓ | This also fixes an old bug: `closed` ("join requests are ignored") was published for every channel, even open channels that accept joins. - **CLI and SDK.** `buzz channels update --join-role guest|member`. `buzz_sdk::build_update_channel` takes a new `join_role` argument and always writes it as an explicit tag. - **Docs.** `NOSTR.md` has an "Announce channels" section with the role table and the flag table. - **Tests.** Relay end-to-end tests, run in the CI relay E2E step: - `test_nip29_announce_channel_wire`: who can set `join_role`, the kind:39000 flags, joining as a guest, refused guest and non-member posts, reactions and adds, member posts, a member making a guest a member who then posts, changing the setting back without changing roles, and leaving. - `test_nip29_member_raises_guest_agent`: a member who is not the agent's owner can make a guest agent a member. - `test_nip29_announce_channel_wire_workflow_send_needs_write_role`: a guest's workflow message is refused; a member's is accepted. - `test_nip29_departure_wire_archived_channel_allows_self_leave`: guests and members can leave an archived channel. - `test_private_channel_any_member_can_invite` now expects a private-channel guest to be refused when it adds someone (it used to expect success). - `test_nip29_announce_channel_wire_workflow_commands_need_write_role`: saving and triggering a workflow, by a member and by a guest, in announce and normal channels; a guest cannot run a workflow saved while it was a member. - `test_nip29_announce_channel_wire_overlong_name_is_refused_before_storage`: a kind:9002 with an overlong name and `join_role` is refused, and kind:39000 still shows the old settings. - `test_nip29_announce_channel_wire_agent_owner_exception`: an agent's owner, as a guest and as a non-member, can edit and delete the agent's messages, while ordinary guests are still refused. - `test_nip29_guest_is_read_only_in_normal_channel`: a guest in an ordinary channel cannot write, and joining an ordinary channel still gives `member`. Unit tables cover the self-join rule for each `join_role`, and every actor, current role and requested role for the role-change rule. Database tests check the admission rules in `put_member` (`put_member_enforces_announce_admission`), that an add which waits on an uncommitted change to `guest` is decided on the new setting (`put_member_waits_for_a_concurrent_join_role_change`), and that a member can make a guest a member but not an admin. Unit tests cover the name limit and the workflow owner rule (`owner_authority_denies_roles_that_cannot_write`). A relay test covers huddle joins with different roles in the huddle and its parent, and a commit after a demotion, a `join_role` change or a lost membership (`huddle_join_needs_a_write_role_in_the_huddle_and_its_parent`). Lock-order tests: `join_role_change_waits_for_a_roster_publication_on_an_ephemeral_channel` reproduced a real deadlock (`40P01`) against the old order. `f2d_join_lock_order_serializes_membership_and_settings_writers` checks that membership and settings writers wait for a join and then succeed. `removed_creator_cannot_rejoin_a_private_channel` checks that `put_member` refuses a removed creator on a private channel, and `removed_creator_join_racing_a_private_switch_is_refused` holds the membership lock so a removed creator's kind:9021 passes the open-channel check, then makes the channel private before the join continues. Each new test was run against the old code and failed. ## Rollout 1. **Before the deploy, count guest rows** (`SELECT count(*) FROM channel_members WHERE role = 'guest' AND removed_at IS NULL`). We expect none. Any guest that exists loses the ability to post, change the topic and add people when this ships. If some exist, decide first whether to make them members. 2. Deploy. Every channel stays `join_role = member`, so nothing else changes. 3. **Do not set any channel to `join_role = guest` until no old relay is running.** Old relays ignore the column, so they would let guests and non-members write in that channel. 4. Rerun the `buzz-admin` channel reconcile so open channels drop the wrong `closed` flag. ## Migration and rollback - Migration `0067` adds `channels.join_role TEXT NOT NULL DEFAULT 'member'` with a CHECK constraint. Postgres stores a constant default in table metadata, so existing rows are not rewritten and there is no backfill. The relay runs the migration at startup. - Existing channels keep the old `closed` flag until their next change, or until the reconcile in Rollout step 4. - **Before rolling back the relay**, set every announce channel back to `join_role = member`. An older relay ignores the column and does not stop guests from writing, so those channels would accept posts from their guests and give `member` to new joiners again. ## Not in this PR Client UI: a Follow button, hiding the composer for guests, and an admin toggle. Clients that ignore the new tag keep working. A guest who tries to post sees the `restricted` error. ## Stack 1. #8143 (this PR): announce channels 2. #8494: store the bot role only for keys with a recorded agent owner --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Co-authored-by: Larry <627498bd4bd1f281a16431e3c6cce3b5c25b6692798c78672298aefbf2f8f8b5@buzz.block.builderlab.xyz> |

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. --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Co-authored-by: Larry <627498bd4bd1f281a16431e3c6cce3b5c25b6692798c78672298aefbf2f8f8b5@buzz.block.builderlab.xyz> |

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.

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`. --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Co-authored-by: Larry <627498bd4bd1f281a16431e3c6cce3b5c25b6692798c78672298aefbf2f8f8b5@buzz.block.builderlab.xyz> |

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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Signed-off-by: Jason Holmes <holmes@squareup.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

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.

owner`/`reply_to`)

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. --------- Signed-off-by: Will Pfleger <wpfleger@block.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> |
