feat(db): expose connection setup metrics (#7286)
## Why
Current pool metrics show checkout outcomes and pool state after the
fact. They do not show when a checkout began or which writer-connection
setup step failed. During startup and pool growth, operators need to
distinguish pool saturation from a slow or unsafe connection setup.
## What
- Count every instrumented database checkout when it starts, with a
fixed operation label.
- Measure writer-pool creation and every physical writer connection
across `physical_connect`, `created_at_floor`, `session_timeouts`,
`isolation`, and `ready`.
- Publish fixed-cardinality start, terminal-outcome, duration, and
waiter metrics without database URLs, SQL, raw errors, connection
ordinals, or per-connection lifecycle logs.
- Document how to identify the active setup bottleneck during a rollout
or incident.
## How
The existing typed checkout wrapper records starts and current waiters.
The huddle-history path uses that wrapper instead of a raw pool
checkout.
The production SQLx `after_connect` hook records start, terminal
outcome, and duration for each sequential safety step. A drop guard
records cancellation once if setup exits before a terminal result. Fixed
enums keep every label bounded.
For a phase, `started_total - sum(attempts_total)` is the number of
in-progress attempts on that pod. Because setup is sequential, a later
phase starting also proves the earlier phases succeeded.
The database path emits metrics only. This PR intentionally does not add
per-connection lifecycle receipts or direct `stderr` writes.
## Risk
Medium. This changes the production writer-pool `after_connect` hook and
adds one counter update to instrumented checkout paths. It does not
change the database safety statements or their failure behavior. The
telemetry has fixed labels and no per-connection identifiers.
## Testing
At exact head `ffb5fcb114a9c986ffd0cb2cfc9d413a32d5b1aa`, a release
relay was started against isolated local PostgreSQL, Redis, and MinIO
services. The main health endpoint returned `ok`, readiness returned
`{"status":"ready"}`, the connection-step metrics were exported, and no
database lifecycle receipts were emitted. A release CLI then created a
channel, sent a message, and read the same event back successfully.
The earlier staging deployment used pre-rebase head
`f58e9480a4f068db0c591f604fd6800fdd4bfc45`. The deployed
multi-architecture image came from [GitHub Actions run
33780888255](https://github.com/block/buzz/actions/runs/33780888255),
manifest
`sha256:b9351fa644e08376cbe1999f9bee311d33d1799a68eadef7929c4f862a832fec`.
The [staging
deployment](https://github.com/squareup/builderbot-platform-core-infrastructure/pull/317)
brought both pods in ReplicaSet `buzz-6c8758bd7d` to Ready with zero
restarts, and the connection metrics produced data in the [rollout
dashboard](https://app.datadoghq.com/dashboard/tm7-qxr-wt2/buzz-startup--rollout-safety).
That staging image predates the cleanup that removed per-connection
lifecycle logs; the metric schema and database safety statements are
unchanged.
## Verification
- `cargo test -p buzz-db -- --test-threads=1`: 128 tests passed across
the package and integration target; 255 opt-in tests remained ignored.
- Four opt-in production-path PostgreSQL regressions passed: initial
minimum connections, post-startup pool growth, isolation failure, and
session-timeout setup failure.
- All 35 relay media tests passed against the isolated PostgreSQL
database.
- Rust formatting, workspace clippy, desktop/Tauri clippy, web checks,
mobile analysis, security checks, and file-size policy checks passed.
- The repository-wide unit stage also exposed three unrelated existing
`buzz-acp` failures: one timing-sensitive keepalive test and two
environment-default tests.
## Bigger picture
This is the database-metrics part of the startup and rollout
observability work. The early-startup lifecycle foundation merged in
#7258, so the rebase removed that duplicate commit from this PR.

Isolate S3 storage metrics from the relay (#7543)
## Why **This PR moves the S3 storage scan out of the serving relay and into a separate batch job.** The job saves a complete result in PostgreSQL. The relay reads that result, exports the existing storage totals, and reports the snapshot's freshness and database-read health. ```text Today: relay -> scan S3 -> calculate totals -> Datadog metrics After rollout: CronJob -> scan S3 -> PostgreSQL snapshot -> relay -> Datadog metrics ``` The code in this PR is the new pipeline. It adds the worker, database snapshot, relay read mode, and Helm CronJob template. It does **not** enable the pipeline in production. The chart keeps the CronJob disabled, and the relay keeps its current inline mode by default. [squareup/builderbot-platform-core-infrastructure#244](https://github.com/squareup/builderbot-platform-core-infrastructure/pull/244) will set the production limits, enable the job, and switch the relay to the saved snapshot after this PR merges. The relay currently lists the media bucket once an hour and calculates storage totals inside the serving process. The production bucket now exceeds the relay's one million object cap, so each sweep fails and the last good per-community values remain stale. The Datadog dashboard can no longer show current storage use by community. Raising that cap inside the serving relay would move a larger, memory-heavy scan into the process that owns live WebSocket connections. The scan retains state for unique blob hashes and community bindings, so its memory use grows with the bucket. A large scan could raise relay memory use, trigger restarts, and drop user connections. The goal is to restore current metrics without putting a production-scale bucket scan in the relay's failure domain. No media objects move or change. Only the process that calculates the totals and the handoff to the relay change. ## What - Add `buzz-admin storage-snapshot`, a run-once worker that scans S3 and saves one complete accounting snapshot in PostgreSQL. - Add `external` relay mode to read the saved snapshot. Keep the current `inline` mode as the default, and add `off` as a fail-closed option. - Add an opt-in Helm CronJob for the worker. The 10 million object cap exists only on this Job. - Keep the current fleet and per-community gauges, and add snapshot age, generation duration, configured cap, cap utilization, and database-load health gauges. - Add an additive migration for the latest complete snapshot and its run metadata. ## Overall plan 1. Merge this PR to add the worker, database handoff, relay modes, and disabled-by-default chart support. This step does not change production behavior. 2. Publish the relay image and Helm chart `0.1.9` from `main`. 3. Update [squareup/builderbot-platform-core-infrastructure#244](https://github.com/squareup/builderbot-platform-core-infrastructure/pull/244) to pin those final artifacts and rerender its manifests. 4. Use the infrastructure PR to deploy the CronJob with a 10 million object cap, a one-hour deadline, and a 20 GiB memory limit. 5. Start one manual Job during a staffed window and verify its snapshot, duration, memory use, relay stability, and Datadog output. 6. Keep the daily schedule and `external` relay mode only after that gate passes, then add alerts for stale snapshots, snapshot-load failure, failed jobs, cap pressure, duration, and worker memory. The code and infrastructure remain separate so this PR can ship the mechanism without silently enabling a production-scale scan. The infrastructure PR owns the production settings and rollout gate. ## How ### Complete snapshot handoff The worker takes a deployment-wide PostgreSQL advisory lock before it lists S3. This prevents scheduled and manual workers from overlapping, even if Kubernetes starts both. The final database replacement runs through that same lock-owning session. If the session dies during the scan, publication fails instead of letting the stale worker overwrite its successor. A worker that no longer owns the lock cannot publish through another pooled connection. The worker reads S3 in pages of 1,000 objects and folds each page into physical totals, logical per-community usage, and anomaly counts. It stops before folding a page that would exceed `--max-objects` and emits structured progress every 100,000 objects. The worker replaces the singleton database row only after the full scan succeeds. A listing error, malformed page, cap breach, serialization error, lost lock session, or database error cannot publish a partial snapshot. The last completed snapshot stays available. Each stored result includes its completion time, duration, cap, and image or source revision. PostgreSQL is the handoff between the batch worker and the relay. The worker writes one complete deployment-wide snapshot, and the relay reads that snapshot on its normal leader metrics tick. No new network service or worker endpoint is required. ### Relay behavior `BUZZ_STORAGE_METRICS=inline` keeps the existing in-process sweep and its one million object default. `external` loads the newest completed worker snapshot on each leader metrics tick. `off` emits no storage-family metrics. An unknown value fails closed to `off`. External mode republishes the existing fleet, per-community, and anomaly metric names, so those current queries remain valid. Snapshot handoff health uses a separate family: `buzz_storage_snapshot_age_seconds`, `buzz_storage_snapshot_duration_seconds`, `buzz_storage_snapshot_max_objects`, `buzz_storage_snapshot_cap_utilization`, and `buzz_storage_snapshot_load_ok`. The `buzz_storage_sweep_*` gauges remain inline-only because they describe a scan attempted by the relay process. External mode does not synthesize `sweep_ok=1` from the last successful database row: an old row proves only that an earlier worker completed. Kubernetes CronJob/Job status is authoritative for the latest worker result, including non-zero exit, deadline expiry, and OOM termination. The relay keeps the last complete snapshot available when a worker run fails. Snapshot age shows that no replacement arrived on schedule, while `buzz_storage_snapshot_load_ok` distinguishes staleness from a missing row, database read failure, or invalid payload. If a community disappears, changes host, or leaves the configured emission scope, the relay zeroes the old labeled series instead of leaving stale values behind. Per-community bytes are logical referenced media usage. If two communities reference the same blob, each community receives the blob's bytes. Fleet physical totals still count each S3 object once. This PR preserves those existing metric semantics. ### Deployment boundary The CronJob is disabled by default. When enabled, it uses `concurrencyPolicy: Forbid`, no retry, a configurable active deadline, bounded history, explicit CPU and memory resources, a read-only root filesystem, and no Istio sidecar by default. The worker receives only `DATABASE_URL`, S3 settings, optional S3 credential references, and the code revision. It does not receive the relay private key, Git hook HMAC secret, Redis URL, or the full relay secret as environment variables. Operators may reuse the Buzz service account or select a dedicated one. ### Non-goals - This PR does not enable the worker or `external` mode in production. - This PR does not change media uploads, object ownership, retention, or deletion. - This PR does not change the names or meaning of the existing fleet, per-community, or anomaly storage gauges. - This PR does not add a lease service or allow multiple workers to publish concurrently. ## Risk The application and chart defaults do not enable the new worker or raise the serving relay's cap. The database change is an additive deployment-global singleton table. The relay's default remains `inline`, so merging this PR alone does not change the active metrics path. The main rollout risk is worker memory use because the fold retains state for distinct blob hashes and community bindings. The first production-sized run must confirm peak memory and duration before the schedule is trusted. The 10 million cap and one-hour deadline bound the first deployment, but they do not replace measurement. External mode also needs stale-snapshot, snapshot-load, and job-failure monitors because the relay intentionally keeps publishing the last complete result after a failed job or read error. This behavior avoids gaps and partial data, while snapshot age and load health tell operators when the result or PostgreSQL handoff needs attention. Job status remains necessary for immediate failures and termination reasons that a killed process cannot record itself. ## Testing No production S3 scan was run from this PR. Automated regressions verify that external mode keeps stale last-good totals visible without emitting inline attempt-health gauges, reports database-load failure while retaining the cache, and leaves inline telemetry unchanged. Mutation checks also prove those tests fail if external mode is routed through inline emission or a failed load is reported as healthy. After deployment, create one manual Job from the CronJob during a staffed window. Require a completed Job, exactly one new snapshot, fewer objects than the configured cap, acceptable duration and peak memory, no relay restart regression, restored Datadog points, and no OpenMetrics sample truncation. ## Next steps 1. Complete review and merge this PR. 2. Publish chart `0.1.9` and the final main-branch relay image. 3. Replace the provisional pins in [squareup/builderbot-platform-core-infrastructure#244](https://github.com/squareup/builderbot-platform-core-infrastructure/pull/244), rerender, and require clean CI. 4. Run the staffed manual Job gate and record object count, peak memory, duration, snapshot revision, and relay stability. 5. Confirm the relay reads the new snapshot in `external` mode and the existing `block.buzz_relay.*` storage series update again. 6. Enable the daily 03:17 UTC schedule and add dashboard panels and monitors for snapshot age, snapshot-load health, Job failures, cap pressure, duration, and worker memory. If production must roll back to an older relay image, set `BUZZ_STORAGE_METRICS=off` first. Older images do not understand `external` and would resume the failing inline scan. ## Bigger picture This is the application half of the storage-metrics repair. The paired infrastructure PR owns the production resource limits, schedule, artifact pins, secret boundary, and monitored rollout. Keeping those changes separate lets this PR remain safe by default while still providing a complete path to current per-community S3 totals. Related issue: N/A.

Add authenticated WebSocket recovery telemetry (#7546)
## Summary
Argo rollout recovery needs to distinguish an open WebSocket from a
connection that completed NIP-42 authentication and is usable. The relay
currently exposes total WebSocket connections, but it cannot answer
whether authenticated clients recovered after a pod drain or why
authentication failed.
This change adds a bounded recovery contract:
- `buzz_auth_attempts_total{method="nip42"}`
- `buzz_auth_outcomes_total{method="nip42",outcome}`
- `buzz_auth_duration_seconds{method="nip42",outcome}`
- `buzz_ws_authenticated_connections_active`
- `buzz_auth_post_terminal_frames_total{state}`
`buzz_auth_attempts_total` now has one consistent recovery-oriented
unit: a challenge lifecycle successfully queued to the connection
writer. This intentionally replaces the historical unit of AUTH frames
that reached the pending handler. AUTH frames received after a lifecycle
is already authenticated or failed are protocol noise; they use the
separate bounded post-terminal counter and cannot inflate rollout-gating
attempts or outcomes.
Each issued challenge reaches exactly one terminal outcome.
Authentication transitions and active-gauge changes share one short
synchronous state lock, cancellation can claim a pending database-backed
AUTH before a late handler result, and a drop guard reconciles aborted
or panicked connection futures. Accounting is terminalized before writer
joins, while terminal socket delivery has a one-second best-effort bound
so a stalled sink cannot retain the authenticated gauge or connection
permit indefinitely.
Dependency failures are distinct from policy verdicts: allowlist and
relay-membership lookup errors now emit `allowlist_check_error` and
`relay_membership_check_error`, never `allowlist_denied` or
`not_relay_member`. The fail-closed allow/deny policy is unchanged. All
rollout-facing labels come from fixed enums; identities, challenges,
URLs, and raw error strings are never exported.
All fixed counter and histogram label sets, including zero histogram
buckets, counts, and sums, are present on the first real exporter
scrape. This is the first implementation slice of the
rollout-reliability plan. A later PR will consume these metrics from
opt-in Argo Rollout analysis; merging this PR alone does not change
deployment behavior.
### Related issue
None found.
### Testing
Validated at final head `f9992cac835284c25ee0f99e17ddba0b932d7c69`,
which contains current `origin/main`:
- `cargo fmt --all -- --check`
- `cargo clippy -p buzz-relay --all-targets -- -D warnings`
- compiled every `buzz-relay` test target
- release builds for `buzz-relay`, `buzz`, `buzz-admin`, and
`buzz-test-cli`
- 16/16 connection lifecycle/writer/production-dispatch tests
- 7/7 AUTH handler tests
- bounded metric-contract exporter test
- 13/13 relay main-target tests (1 PostgreSQL-only test ignored)
- 9/9 real boot-lifecycle tests, including a production install and
first Prometheus scrape
Mutation checks proved that the production regressions fail when any of
these are removed or reintroduced:
- challenge attempt start in `handle_active_connection`
- authentication series initialization in the real metric installer
- separation of post-terminal AUTH floods from authoritative attempts
The exact-head release binaries were also exercised against the isolated
review database:
1. Started the release relay and verified health/readiness.
2. Created a channel with the regular CLI.
3. Held one authenticated WebSocket subscription open and authenticated
a second WebSocket publisher.
4. Published a message and read it back through the regular CLI.
5. Observed `attempt_delta=2`, `success_delta=2`,
`active_while_subscribed=1`, and `active_after_disconnect=0`.
6. Sent SIGTERM and waited for graceful relay shutdown.
### Local caveat
The full relay library target consistently reached 1,049 passes with 89
intentionally ignored tests, but the untouched
`api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo`
intermittently returned HTTP 504 instead of 200. One isolated rerun
passed; later isolated and full reruns reproduced the 504. No mesh files
are changed by this PR, and all changed-path, main-target,
boot-lifecycle, lint, build, mutation, and live-local checks above
passed at the final head.

Instrument database pool roles (#7356)
## What
Name the relay's four Postgres pool roles—writer, reader, audit, and
search—and export one fixed-cardinality utilization metric contract for
all of them. Existing writer and reader gauges remain unchanged.
## Why
Audit and search already use separate pools, but they are missing from
pool pressure telemetry. Operators cannot see all process-level
connection demand before setting a deployment-wide connection budget.
## How
A closed `DbPoolRole` vocabulary now labels
`buzz_db_pool_connections{pool_role,state}` and
`buzz_db_pool_configured{pool_role}`. The relay retains cheap pool
clones for statistics only; ownership, capacities, timeouts, query
routing, and failure behavior do not change. The docs also replace the
stale async search-index description with the generated-column behavior
used today.
This simplifies four ad hoc observability states into one bounded model
without adding a pool manager or changing service boundaries.
## Risk
Low to moderate. This changes relay metrics and pool construction
plumbing, but not SQL execution or routing. Legacy metric names remain
available for current dashboards.
## Testing
- Push gate at `3f5468a0463bdfc5879bcdd3878fa06b42ca84c2`: all 14 Rust
test lanes passed; desktop Tauri checks passed.
- Blox: `cargo test --workspace --all-targets` with repository-declared
Postgres services.
- Blox: `cargo clippy --workspace --all-targets -- -D warnings`.
- Blox: `cargo fmt --all -- --check`.
## Bigger picture
Aggregate deployment budget enforcement remains deferred. This PR
exposes the per-role facts that a later deployment-policy change can
consume.

fix(db): allow naturally expired push lease replacement (#7653)
## Summary Allow a naturally expired push lease to be replaced by a newer lease for the same author and installation. ## Failure mode Expiry cleanup marked the old lease inactive but left active-only fields populated. The push_leases_check constraint requires those fields to be NULL when a lease is inactive. When the client later registered a replacement lease, the cleanup ran before the replacement and violated the constraint with SQLSTATE 23514. The transaction rolled back, so the replacement failed instead of taking over the expired lease. ## Fix Clear all active-only fields as part of natural-expiry cleanup, preserving the existing constraint and replacement flow. No schema change is required. ## Testing - Passed the focused Postgres regression test: cargo test -p buzz-db replacing_naturally_expired_lease_replaces_old_state -- --ignored - Passed scripts/test-postgres-test-discovery.sh - Ran just ci: formatting, lint, security, file-size, desktop, web, mobile, and 12 unit-test lanes passed. The overall run was red only because existing timing-sensitive buzz-acp tests failed. - The pre-push test-unit hook reproduced the same unrelated buzz-acp failures, so the already-run verification was documented and the branch was published with that hook bypassed. ## Related issue No matching open issue or pull request was found. ## Scope One file changed: crates/buzz-db/src/store/push.rs. The test uses the production accept_lease_event path and identifies the replacement by its cryptographic source event ID and generation. Signed-off-by: Jarrod Sibbison <jsibbison@squareup.com> |

feat(push): make gateway origin configurable (#7261)
Make the push gateway origin configurable across the relay, gateway, mobile client, and deployment chart. This is a fresh deployment. The gateway has only run on personal development infrastructure, and push has no existing enabled users. Legacy migration, configured-to-unconfigured mobile transitions, and rolling upgrades from pre-launch gateway binaries are not supported. Populated pre-launch databases are rejected with an informative error before migrations run; their data is untouched. Mobile builds may omit the gateway URL, leaving push unavailable. Once push is enabled, subsequent builds must retain that configuration. ### Validation - All applicable CI checks pass at `5f546cfaf403f0386f146d213adfb4392f4ec29c`, including Rust, mobile/Swift, desktop/integration, security, image builds, and Helm checks. An unrelated agent cancellation test passed on retry. - PostgreSQL CI passed 384 tests, including the production-entry-point regression for refusing populated pre-launch databases before migrations, fresh initialization, and subsequent initialized deployments. - Focused local validation passed all 10 gateway PostgreSQL tests under the CI discovery filter and all 3 unconfigured-mobile tests. Repository-wide PostgreSQL discovery validation and the complete pre-push hooks passed. - Physical-device APNs/App Attest behavior and deployment to a live cluster were not verified in this work. --------- Signed-off-by: Tom Brow <tomb@block.xyz> Co-authored-by: Codex <noreply@openai.com> |

Deduplicate thread context by ACP session delivery (#7620)
## Summary Buzz can repeat a thread reply in later prompts after the provider already received that event as context. The old fix treated every message signed by the agent key as retained by the current provider session. That could hide an unseen heartbeat reply because independent sessions share the same signing key. This PR now removes only exact event IDs already delivered to the live ACP session. It uses bounded overfetch so removed events do not shrink the new-context window, and it preserves unseen same-key replies from other sessions. The context header reports `truncated=true` whenever session history was omitted. The harness calls `/count` only when the relay query finds a sentinel beyond its fetch window. This deliberately does not parse event IDs from shell output. A reply that the agent just published may appear once in the next context delta; after that event reaches the provider as context, later prompts omit it. --------- Signed-off-by: Salman Mohammed <smohammed@squareup.com> |

feat(buzz-agent): add opt-in workspace-scoped Databricks reuse (#7606)
Posted by Brain, Wes Billman’s AI assistant, on behalf of `wesbillman`. ## Summary Add an opt-in `databricks::DatabricksConnection` over the existing PKCE/coordinator and v2 catalog machinery. It accepts an explicit HTTPS workspace origin, absolute caller-owned cache root, and browser opener; it does not start an agent or infer credentials/host from the environment. - Validate both OAuth endpoints on the actual discovery response used for grants; native HTTP redirects are disabled and requests have a 30-second timeout. - Keep strict cache/single-flight state in a separate namespace. Connect is explicit/user-initiated; catalog lookup and its one 401 refresh stay headless. Tokens are not exposed by the connection API. - Preserve existing legacy constructors, endpoint/redirect policy, cache layout, intents, and catalog filtering/pagination/partial/default semantics. No internal host default, credential migration, app integration or release configuration changes. ### Intentional shared changes OAuth success/discovery JSON is capped at 1 MiB; error JSON at 16 KiB. Oversized/malformed responses are infrastructure failures, while bounded client-error `invalid_grant` retains its existing classification. OAuth diagnostics omit raw bodies/URLs/opener/callback details. Overflowing token expiry returns an infrastructure failure. These changes affect legacy callers too and have synthetic regression coverage. See [the reuse contract](crates/buzz-agent/DATABRICKS_REUSE.md) for API, compatibility and caller obligations. Total operation deadlines, stale-result fencing, private root ownership, nonlogging opener behavior and credential-removal UX remain the caller’s responsibility. ### Related issue Related discovery work: #6918. Searched existing Databricks PRs and OAuth issues; no duplicate of this strict opt-in API was found among those results. This is a new reuse boundary, not a claim of a live credential leak. ### Testing Published head: `cf33eb2f4f267d5808e068e35127d5504f0bc674`, based on main `78618804ec86a014524ad7d1fb55928e8f5c3edf`. Two implementation/doc commits were transplanted from a release-derived local base to exclude unrelated release files. `git range-diff` reports both patches unchanged; independent source review of the transplant found no blocker. **At the published head:** normal pre-push hooks passed: branch skew, push-head scope, file-size checks, Rust test lane and desktop Tauri Clippy/tests. The fallback Rust lane actually ran `buzz-agent --lib`: 542 passed / 1 ignored, NOT the full package integration suite. Hosted full package/repository CI remains pending. The first push attempt was interrupted by the command runner’s 300-second limit; the second completed normally with all hooks enabled. **At reviewed implementation checkpoint `8cb3b72d4`:** 16 strict, 27 auth, 32 catalog and 63 coordinator/OAuth/CLI tests passed, independently rerun; 18 author-selected mutations and four independent reviewer mutations failed tests with passing restored controls. The subsequent `539319411` delta changed only two doc-comment blocks. These earlier test/mutation results are not silently attributed to the rebased head. Synthetic coverage includes HTTPS grants/catalog, off-origin endpoint and redirect rejection, cancellation/socket/listener cleanup, host/root/legacy namespace isolation, bounded declared/chunked bodies and exact-limit controls, redaction with positive log capture, malformed expiry, legacy endpoint/redirect controls, and real CLI cached-auth aliases. Desktop native checks used fail-closed sidecar stubs: compile/test evidence, **not** a runnable or packaged app. No real provider credentials, browser sign-in, app launch, or agent cutover was performed. Cross-platform execution and real-provider acceptance remain separate gates. No merge or downstream adoption is requested by this PR. --------- Signed-off-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz> Co-authored-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz> |

refactor(buzz-acp): point agents at buzz --help instead of a command table (#7586)
## Summary The ACP base prompt carried a `Group | Key commands` table for the `buzz` CLI — a second copy of a surface that already documents itself, with nothing tying it to the parser. It had already drifted: 16 of the CLI's 23 groups (missing `emoji`, `gifs`, `notes`, `patches`, `media`, `moderation`, `pack`) and 50 of the 91 subcommands under the groups it did list. The adjacent exit-code line stopped at 4; the CLI has a 5th (5 = write conflict, NIP-33 LWW). #7584 was the prerequisite: `buzz --help` now renders the full command tree — every group, its subcommands, and their descriptions — in one invocation (199 lines, 13 KB), generated from clap's own command definition, so it cannot drift. `buzz -h` still prints the group-level summary. Pointing the prompt at `--help` was not viable before that, because discovering `buzz messages send` cost a second call and discovering `buzz canvas set` exists cost a third. So this replaces the table with a pointer to `buzz --help`, fixes the exit codes, and adds the one CLI ergonomic that `--help` does not make obvious (`--format compact` is a global flag that goes before the subcommand). Everything after the table is kept verbatim — it is the non-discoverable semantics `--help` cannot express: multiline content through stdin, the `BUZZ_AUTH_TAG` requirement for agent drafts, `--channel` on `pr open`, the `link` field, mention and assignment rules.

feat(buzz-cli): render an agent-friendly command tree in --help (#7584)
## Summary
`crates/buzz-acp/src/base_prompt.md` carries a hand-maintained `Group |
Key commands` table of the `buzz` CLI. It is a second copy of a surface
that already documents itself, and it has drifted: it lists 16 of the
CLI's 23 groups (missing `emoji`, `gifs`, `notes`, `patches`, `media`,
`moderation`, `pack`) and omits roughly two-thirds of the subcommands
under the groups it does list. its hard to keep it in sync.
The reason the base prompt duplicates that inventory is that `buzz
--help` was not good enough to lean on. It listed 23 group names with
nothing under them, so finding `buzz messages send` cost a second
`--help` call and learning that `buzz canvas set` exists at all cost a
third. An agent paying per group reasonably prefers a stale table it
already has.
This PR fixes the help output so the prompt can point at it instead.
`buzz --help` now prints the whole tree — every group, its subcommands,
and their descriptions — in one invocation:
**Before**
```
Commands:
messages Send, read, search, and manage messages
channels Create, configure, and manage channels
canvas Get and set channel canvas documents
```
**After**
```
Commands:
messages Send, read, search, and manage messages
send Send a message to a channel
send-diff Send a code diff / patch to a channel
edit Edit a previously sent message
...
repos Announce and discover git repositories (NIP-34)
protect Manage branch and tag protection rules on one of your repositories
list List the repository's protection rules
```
This change is formatting only: it adds no new data and no new commands.

feat(git): add default-branch management to relay and CLI (#7562)
Authored by Brain and opened on behalf of Wes (`wesbillman`).
## Summary
Add `buzz repos default-branch get/set` and the relay operation it
needs. Git push changes branch tips but cannot select the server's
symbolic HEAD. This selects an existing branch without deleting
branches, moving refs, or changing packs.
- Reuse immutable Git manifests and captured-ETag CAS; concurrent
pushes/default changes conflict, including stale no-ops.
- Require request-specific NIP-98, body binding, fail-closed replay
protection, host tenancy, current channel membership and
repository-management authority. Push/project roles alone are
insufficient.
- Send the CLI mutation once, without redirects; ambiguous delivery
retains the observed digest and is non-retryable.
- Document the narrow HTTP exception to Nostr-first, delegation scope
and admission-time ACL revocation. Kind:30618 remains derived; the
manifest CAS is authoritative.
- Register the Postgres/Redis/MinIO route and fresh-clone tests in the
existing Backend Integration lane.
## Review fixes — `7457bda50afa6b52e36315572fa96928b2e21db6`
- Reject signed valueless `payload` tags when verifying a body; preserve
the shared verifier's intentional absent-payload compatibility. The real
settings route now proves 401, unchanged manifest pointer, and unchanged
kind:30618 event IDs for malformed and other invalid credentials.
- Require a nonempty returned branch and `head == refs/heads/{branch}`;
SET additionally requires the returned branch to equal the attempted
branch. Malformed/mismatched mutation responses remain non-retryable
`DeliveryUnknown`, retaining the attempted branch and original digest.
Invalid reads fail before any POST.
- Strengthen the later-push/fresh-clone regression to select
`release/v1` while `main` exists.
## Verification
At `7457bda50afa6b52e36315572fa96928b2e21db6`:
- Full pre-push passed (all 14 Rust test groups, serialized Tauri
tests/clippy, file-size and branch-skew gates; 522 seconds). No hooks
disabled.
- All four isolated Postgres/Redis/MinIO settings tests pass, including
real Smart HTTP `ls-remote --symref` and fresh clone on `release/v1`.
- All 15 focused NIP-98 verifier tests and three default-branch CLI
tests pass; malformed credentials and missing-branch responses were
reproduced failing before the fixes.
- Five targeted mutants are killed: restoring the valueless-payload
bypass, weakening canonical HEAD validation, accepting an empty branch,
dropping requested-branch confirmation, and omitting hydrated HEAD for
the selected non-main branch. Mutations ran in a separate worktree and
target directory; original patch bytes were verified restored.
- `cargo clippy -p buzz-auth -p buzz-cli -p buzz-relay --all-targets --
-D warnings`, formatting, diff and file-size checks pass on the fixed
tree.
Earlier validation at `bb195b140`: seven Git authorization database
regressions and 28 existing transport tests passed (three infrastructure
cases in that module not selected); four mutations killed
management/replay/CAS/redirect regressions. Full pre-push passed with
`RUST_TEST_THREADS=1` (all 14 Rust groups, Tauri clippy and 3,173 tests,
size/branch-skew gates). Serial execution avoids an unrelated
process-global Desktop discovery counter flake; no hooks disabled or
Desktop changes.
Carl and Jude's review findings are addressed in the new head; **fresh
reviewer and exact-head security confirmation remain required**. The
earlier source review is not approval of this revision. No claim of
green new-head CI.
## Rollout
Merge and **deploy the relay support first**, then build/use the updated
CLI and explicitly set/verify the desired default. No schema migration.
This PR does not deploy anything or change a live repository.

fix(acp): integrate the Buzz Pi adapter fork (#7552)
## Summary PR #7335 worked around missing Pi adapter support by generating a private Pi launcher and injecting Buzz's standing prompt and skills at process launch. The Buzz Pi fork now carries the required adapter extensions, so this removes that launcher and returns prompt construction to the normal ACP session path while retaining the base-prompt composition introduced by #7335. The Pi preset now installs `salman1993/pi-acp` and launches its renamed `buzz-pi-acp` binary. Buzz adds `-- --skill <harness-cwd>/.agents/skills` only when launching that binary, sends the complete composed prompt as the `_meta.systemPrompt` replacement string on `session/new` only when `initialize.agentInfo.name` is `buzz-pi-acp`, and sends the scoped title alongside it as `_meta.sessionTitle`. The fork identity is treated as system-prompt capable regardless of its reported ACP protocol version, which prevents duplicate legacy user-message framing. Upstream `pi-acp` does not receive either fork-specific behavior. Observer transcript projection accepts the string, `{ replace }`, and `{ append }` metadata forms. The fork now stores restore metadata in one atomic file per session under `~/.pi/buzz-pi-acp/sessions/`. This prevents concurrent Buzz workers from overwriting another session's prompt or title. The fix landed in [salman1993/pi-acp#9](https://github.com/salman1993/pi-acp/pull/9). This supersedes the closed #7508. No agent-configuration rules changed; this changes the Buzz Pi adapter contract and launch arguments. ### Related issue #7329 ### Testing Installed fork commit `09cf07e436b8f18e52401558f988f31a15702313` through the documented Git URL. The installed bundle matched the committed `dist/index.js` byte for byte and contained the `~/.pi/buzz-pi-acp` metadata path. The fork's 106 non-skipped tests, typecheck, and lint pass. Ran the ignored real-Pi integration test through Buzz's production session composer. The test exercised the renamed package, `agentInfo.name`, and the new per-session metadata store. Base, persona, team, core-memory, huddle, canvas, and skill markers each appeared once after switching sessions and again after restarting the adapter, while the other session and Pi's native default prompt were absent. Added regression coverage proving `buzz-pi-acp` receives fork-specific system-prompt metadata and managed skills while upstream `pi-acp` does not. `just ci` passes.

fix(relay): reject presence updates when Redis storage fails (#7532)
## Summary
- Reject kind:20001 presence events with `OK false` / `error: presence
storage unavailable` when Redis SET or DEL fails, before publishing,
local fan-out, or local-event marking.
- Preserve the producer contract needed by snapshot-confirming
consumers: delivered live presence must follow successful mutation of
the Redis state read by snapshots.
- Classify those backend rejections with the existing `IngestError`
taxonomy so a presence storage outage counts as
`buzz_events_rejected_total{transport="ws",reason="error"}`, not client
`reason="invalid"`; genuine client-input refusals (verification failure,
membership gates) stay `invalid`, and every wire message is an unchanged
fixed sanitized string (review follow-up, no protocol wording change).
- Add actual `handle_event` integration coverage for rejected
online/offline transitions, healthy online→offline
accepted/stored/fanned-out behavior, and the rejection-counter routing
on storage failure with an invalid-signature control.
This is standalone on main; it does not depend on the mobile
implementation. Deploy this relay prerequisite before relying on #7526's
snapshot-confirmation policy. Existing
pubsub-failure-after-successful-storage behavior and disconnect TTL
cleanup are deliberately unchanged. A storage error may be an ambiguous
write outcome, not a rollback guarantee; the rejected event is not
published by this handler. Clients may retry the generic `error:`
rejection. Desktop's 60s heartbeat retries non-offline presence, not
every explicit offline transition.
### Related issue
Addresses the relay prerequisite identified in [#7526 review
5157607827](https://github.com/block/buzz/pull/7526#pullrequestreview-5157607827).
Searched open presence/storage PRs; no duplicate relay storage-error
rejection fix found. #7382/#7383/#7526 heads and bases are unchanged.
### Testing
Exact head: `389174df29cc02d0f885c03209eff661d8bb2ec0` (+380/-13; 393
total), one commit `389174df2` on top of the reviewed `c031d6eb1`
(DCO-signed; base `bfc384855889432df4a333a0edf3080f332ee169` unchanged).
- PASS: `cargo fmt --all -- --check`, `cargo clippy -p buzz-relay
--all-targets -- -D warnings`, `git diff --check`, `just
file-size-check`, PostgreSQL discovery validation — all run at the exact
final head with a clean tree before and after.
- PASS: documented native `scripts/postgres-test-run.sh -p buzz-relay
--lib --tests`: **89/89** actual integration tests, including the four
presence cases (online/offline storage rejection, healthy
online→offline, and the new rejection-classification case). Owned
PostgreSQL 17/Redis on isolated loopback ports, schema plus
reconciliation applied; no shared development database.
- PASS: explicit `cargo test -p buzz-relay presence_storage -- --ignored
--nocapture`: **4/4**, not skipped.
- Full isolated relay crate suite at the final head (`cargo nextest run
-p buzz-relay --lib --tests`): **1062 run: 1062 passed, 94 skipped**.
The previously failing
`api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo` passed
in this run (1.5s); it is a known timing-sensitive main baseline failure
tracked open in #7140 and untouched by this PR, so this single passing
run is reported as-is and does not claim environmental clearance or
close #7140. No full-suite-green claim is made beyond this run.
- Mobile is untouched; #7526's existing 2090-test/format/analyze
evidence remains scoped to its unchanged head. Its separate Desktop
Smoke E2E (2) failure remains red; no CI retries requested.

fix(buzz-acp): report missing models without retrying (#7538)
## Summary When an agent reports model-not-found, Buzz retries the unavailable model and delays the failure reply until retries are exhausted. Stop retrying this error and immediately post a threaded recovery notice. The notice tells users to select a different model in agent settings, save, restart the agent to apply the configuration, and re-send their request. This adds one error-handling branch and regression coverage in `buzz-acp`. It matches `-32002` errors containing `model not found`. Other resource-not-found errors, such as stale sessions, retain the existing retry behavior. Detailed error events remain available for diagnosis. The existing restart policy is unchanged. ### Related issue None found in existing issue/PR searches for model-not-found recovery. ### Testing Playwright captured and visually checked the thread UI with seeded conversation data and the exact recovery text. The check opens the request's thread, confirms no reply before the failure, injects the notice, and verifies the full text is visible. [Before/after screenshots](https://github.com/block/buzz/pull/7538#issuecomment-5608196506) show the corrected save-and-restart instructions. These are local test captures, not a deployed provider recovery flow. Generated with Codex --------- Signed-off-by: Diem Nguyen <diem@squareup.com> |

fix(acp): pace targeted overflow recovery on consumer capacity (#7325)
🤖 ## Summary When a Buzz agent falls behind on incoming messages, its connection can make the backlog worse while trying to recover. The connection buffers messages from the relay server until the agent is ready to process them; if that buffer overflows, recovery previously requested history for **every subscribed channel** and paused socket reads while sending those requests. That adds traffic to an already overloaded connection. This change requests history only for affected subscriptions, once the code consuming those messages has room, with at least five seconds between attempts. The recovery path now: - Combines repeated losses into one pending recovery per affected subscription, keeping the oldest dropped timestamp so replay starts early enough. - Waits until at least half the consumer queue is free and the relay's existing rate-limit delay has expired. The queue wakes recovery when space becomes available; recovery does not periodically sample capacity or hold queue space away from live messages. - Attempts one subscription at a time, choosing the least recently attempted so a busy channel cannot crowd out other channels or membership notifications. The five-second delay starts when an attempt finishes, including a failed write; failed writes leave recovery pending. Recovery is paced by available capacity, not by how often messages are lost. This is not a larger buffer or a cutoff that abandons recovery. Subscription identifiers, message filters, replay timestamp overlap and duplicate filtering are unchanged; no downstream agent changes are required. This targets a reproducible overload **amplifier**, not every cause of overload or every catch-up limitation. The initial live overload's cause has not been established. Recovery remains best effort: a successful request write is not proof of delivery, and existing history/retention limits, bounded duplicate tracking and replay limitations still apply. There is no exactly-once or complete catch-up guarantee. A stalled write can still pause socket reads for the existing ten-second timeout; the pacing bound does not cover initial subscriptions, reconnects or other retry paths. ### Related issue Closest related: #5014 (channel re-subscription); also #6661 (membership reconciliation) and #6090 (relay backpressure gap signaling). This addresses local overflow recovery scheduling, not those separate mechanisms. ### Testing Recorded offline comparisons against the previous behavior, with the final implementation at `8000636f3073167c5a5107bb179c7d91160f1729`: | Same fixture: 18 subscriptions, three overload rounds | Before | After | | --- | --- | --- | | Recovery history requests | 108 | 3 | | Ping-response delay | About 4.6 seconds | Below the measurement's 1 ms resolution | A separate bounded-history fixture delivered all 320 events plus subsequent live traffic in **both** versions. Regression coverage exercises the real socket-handling task, including intermittent consumer capacity, fairness, failed writes and cancellation of capacity waits before live delivery. These are synthetic results, not production throughput measurements or evidence of a deployed cure. The full local `RUST_TEST_THREADS=4 just ci` run passed on September 4, 2026. Earlier unsuccessful local runs remain part of the validation history. The [recorded validation evidence and separate desktop follow-up](https://github.com/block/buzz/pull/7325#issuecomment-5540592398) preserve the original desktop mock-history scroll failure, its passing rerun and the remaining investigation. That desktop path does not run the agent connection code; neither this repair nor the passing rerun fixes the observed scroll problem. --------- Signed-off-by: Logan Johnson <loganj@squareup.com> |

feat(mesh): upgrade to mesh-llm 0.76.0-rc8 and recommend Qwen3.8 27B (#6189)
Upgrades Buzz's mesh-llm dependencies through the released `v0.76.0-rc8` tag (`2040765d`), including the Qwen3.8 curated recommendation and rc8's scheduler/runtime improvements. **Scope note:** the earlier open-relay/unenforced-admission mode has been removed from this PR at Mic's direction — it is not a product mode we want. Mesh admission remains roster/allowlist driven, exactly as on `main`: on a relay with no NIP-43 membership snapshot the mesh runs self-only. No NIP-11 mode probing, no mode-transition restarts. A future perimeter/admission strategy for open relays will be designed separately. This PR also: - seeds `BUZZ_AGENT_LLM_TIMEOUT_SECS=660` for mesh agents, above MeshLLM's 600-second backend timeout; - makes `desktop-tauri-clippy` lint both default and `mesh-llm` cfg graphs; - runs the feature-enabled desktop test suite in CI; - recommends Qwen3.8 27B Q4_K_M for 64 GB-and-larger machines, then ladders down through Gemma 4 E4B and Qwen 9B for smaller machines; - keeps stored shared-compute `auto` translated to MeshLLM's supported wire model `mesh`. RC8 verification: - `just ci` passed locally at `92ecc7ec933bdd4df804cc9f28a2b51efa5313c5`. - Pre-push differential gates passed, including both desktop Tauri cfg graphs and package tests. - A prior isolated runtime smoke used the RC8 binary's OpenAI endpoint for a Buzz-shaped system/user/tool/tool-result/final-response loop; all assertions passed and the isolated process was shut down. Perf previously measured on M5 Metal, Qwen3.8-27B-Q4_K_M: TTFT 0.22–0.32 s, ~25 tok/s streaming; agent-shaped turns ~1 s to first token after the first (prefix cache). --------- Signed-off-by: Michael Neale <michael.neale@gmail.com> Signed-off-by: Jimmy <1fe240cd1a8cf775f6f3060f115e5a303181f3abf28ad4cb0c2515f4a02b36a8@meshllm.communities.buzz.xyz> Signed-off-by: Alessandro Joabar <sandro@squareup.com> Co-authored-by: Michael Neale <michael.neale@gmail.com> Co-authored-by: Jimmy <1fe240cd1a8cf775f6f3060f115e5a303181f3abf28ad4cb0c2515f4a02b36a8@meshllm.communities.buzz.xyz> Co-authored-by: Mic Neale <305999590+micspiral@users.noreply.github.com> Co-authored-by: Alessandro Joabar <sandro@squareup.com> |

fix(agent): route GPT-5+ model-service FQNs to Responses (#7358)
## Summary Route Databricks Unity Catalog model services to OpenAI Responses when their service name matches GPT-5 or newer. These models can reject tools plus reasoning on Chat Completions. Match only the service component, using the existing family-token boundaries and a numeric major version. Catalog and schema names cannot select the protocol. Keep neutral effort capabilities and the full model ID unchanged; other services still use MLflow Chat Completions. Keep the Rust and desktop resolvers in sync, add shared boundary cases and a captured-HTTP regression for completion and summarization, and update the documented FQN rule. ### Related issue No duplicate found in searches for “FQN responses” PRs or “astra” issues. Related: #6918 introduced Unity Catalog discovery.

feat(buzz-acp): update base prompt; add buzz context and skills to Pi agents (#7335)
## Summary - launch Pi through a private Buzz wrapper so managed Pi agents receive Buzz's base prompt plus the configured thread/channel session model via `--system-prompt` - load the Buzz workspace skill directory with Pi's repeatable `--skill` flag, making `~/.buzz/.agents/skills/buzz-cli` available alongside Pi's normal global skill discovery - report Pi and `pi-acp` installation states separately so setup guidance points to the missing component `pi-acp` does not currently consume the ACP `session/new` system prompt, but its normal new-session and restore paths do honor `PI_ACP_PI_COMMAND` as the executable used to launch Pi. Buzz reserves that variable and sets it to a private generated launcher. The launcher invokes `pi` from Buzz's effective `PATH`, adds `--system-prompt <file>` and `--skill <workspace>/.agents/skills`, and forwards `pi-acp`'s RPC and session arguments unchanged. This keeps the integration entirely in `block/buzz`, without changes to Pi or `pi-acp`. ### How PI_ACP_PI_COMMAND works in `pi-acp` `PI_ACP_PI_COMMAND` selects one executable; it does not accept arguments. Therefore: ```bash # Does not work PI_ACP_PI_COMMAND="pi --skill ~/.buzz/.agents/skills" ``` Buzz does not expose this variable as user configuration. It creates a private launcher and sets `PI_ACP_PI_COMMAND` only on the `pi-acp` child. Conceptually, that launcher executes: ```sh #!/bin/sh exec pi \ --system-prompt "$PRIVATE_SYSTEM_PROMPT" \ --skill "$HOME/.buzz/.agents/skills" \ "$@" ``` ### Related issue Follow-up to #7208. No duplicate issue or open PR found. ### Testing - `just ci` - `cargo test -p buzz-acp pi_launcher` - `cargo test --manifest-path desktop/src-tauri/Cargo.toml managed_agents::env_vars::tests` - `cargo test --manifest-path desktop/src-tauri/Cargo.toml managed_agents::discovery::presets::tests` - pre-push branch checks No screenshots: the UI change is state-dependent setup guidance only. --- **Update Sep 4, 13:35:** Made `PI_ACP_PI_COMMAND` entirely Buzz-owned. - Managed agent configuration now rejects the variable as a user override. - Buzz always launches `pi` from its effective `PATH` and rejects inherited values before creating its private launcher. - Removed the custom Pi executable discovery path and its internal environment alias. --- **Update Sep 4, 14:03:** Reject inherited `PI_ACP_PI_COMMAND` values instead of replacing them. - Pi startup now fails with an actionable message telling the user to unset the variable. - Removed the Pi-specific exception from the generic ACP environment injection path.

Verify ACP relay events before prompt routing (#7010)

Events with an invalid NIP-01 ID or Schnorr signature are dropped before subscription routing, deduplication, replay-watermark updates, membership handling, or either harness queue. ## Safety Signature verification runs on the blocking pool so cryptographic work does not block the relay task. A verification failure drops only that event and keeps the connection available for subsequent valid traffic. The existing observer-control verification remains as defense in depth.

fix(buzz-acp): bound busy-owner hold to prevent cross-channel starvation (#7337)
## Problem #6732 added a busy-owner hold to the ACP harness: when a scope's recorded session owner (`session_owners`) is checked out on **any** turn, `dispatch_pending` holds the scope's batch instead of dispatching it. The hold was added to keep one provider session per thread — but it is unconditional: it applies to `Conversation` scopes too, and it has no time bound. Under the default `session_policy=channel`, every channel collapses to a single `Conversation` scope, so once two channels' sessions land on the same worker (pass 2 of `try_claim` picks the first idle worker by index, so this happens quickly after any restart), channel A's mention starves behind channel B's in-flight turn — for up to the full `max_turn_duration` (7200s by default) — while other workers sit idle. The only signal is a DEBUG-level log, and the 👀 seen-reaction is added at queue admission *before* the hold decision, so the user sees the agent acknowledge the mention and then nothing. Observed in production on the first day of the v0.5.22 rollout: three separate incidents where a mention got 👀 but no turn started until an unrelated channel's turn ended on the shared worker (in the worst case the blocking turn sat in a single tool call for 6+ minutes). ## Fix One new seam, `AgentPool::hold_decision`, replaces the raw `should_hold_for_busy_owner` check in `dispatch_pending` (the predicate itself is unchanged and remains the inner check): - **`Conversation` scopes never hold.** Channel-policy channels and all DMs dispatch immediately; a busy owner means forking onto an idle worker, exactly the pre-#6732 behavior. This removes the cross-channel head-of-line blocking entirely for the default policy. - **`Thread` scopes hold for a bounded window.** `HOLD_BUSY_OWNER_TIMEOUT` (10s) is measured from the first time the batch is held (`held_since` stamp); once elapsed, the batch stops holding and forks a fresh session on an idle worker, rebuilding thread context from the relay. This preserves #6732's session-continuity intent for the momentary-busy case while capping the worst-case wait. No new timer is needed: held batches are requeued with preserved timestamps and re-evaluated on every dispatch trigger (turn end, relay event, 30s maintenance tick), so the effective worst-case re-check gap on a fully silent system is one maintenance tick. - **Holds are observable.** Holding logs at INFO and a hold expiry logs at WARN (previously DEBUG-only), and both emit observer-feed events (`busy_owner_hold`, `busy_owner_hold_forked`) with the scope, owner index, and held duration. `held_since` is derived state and is cleared on every removal path: dispatch/fork (inside `hold_decision`), `invalidate_channel_sessions`, `invalidate_scope_session`, and `switch_idle_agent_model`. ## Accepted trade-offs - A fork after an expired hold leaves the old owner's now-orphaned thread session in its session map until natural rotation/invalidation — benign, and identical to pre-#6732 fork semantics (`loadSession: false`; sessions are worker-pinned, so migration is not an option). - Under sustained pool exhaustion the hold stamp is cleared on the fork attempt and re-stamped next cycle, so the bound is effectively "timeout after a worker frees up," not absolute wall clock. ## Tests - New table test `hold_decision_covers_variant_session_busy_and_timeout` over the full input space (scope variant × idle-session presence × owner busyness × elapsed vs. window). The `Conversation` + busy-owner row is the cross-channel regression guard; the past-window row guards the bound. Both were mutation-checked: removing the variant gate or the timeout branch fails the suite. - `busy_session_owner_holds_batch_instead_of_forking_session` extended with the Hold → ForkAfterHold transition, the `Conversation` dispatch guard, and `held_since` pruning on channel invalidation. - Scope-invalidation and idle-model-switch tests extended to cover `held_since` cleanup alongside the existing `session_owners` assertions.

refactor(relay): extract NIP-29 membership authorization (#7285)
## Why NIP-29 membership authorization for kinds 9000, 9001, and 9022 was embedded in a large async handler, requiring Postgres and Redis to test and repeating the last-owner rule across five call sites. This addresses [TheSentinel454/buzz#24](https://github.com/TheSentinel454/buzz/issues/24) without adding the broader state/repository abstraction suggested there because HTTP and WebSocket writes already share ingestion. ## What - Extract pure, typed membership authorization decisions while leaving database reads and mutations in `validate_admin_event`. - Preserve existing client-visible errors and independent database last-owner safeguards. - Collapse five last-owner policy restatements into one predicate and share the identical self-departure policy. - Include the relay decision modules in `just test-unit`, so these tests execute in CI. ## Risk Assessment Medium-low. This touches production relay authorization, but intentionally preserves wire behavior and database defense in depth; exhaustive decision tables and relay-backed tests cover the affected paths. ## Simplification This removes repeated policy from the orchestration path and makes the rule set directly testable without introducing a repository trait or second transport path. ## Verification Verified at `15255a090797f85874921120003c645962fefaed`: - `just test-unit` — all 10 package summaries passed. An initial run hit two unrelated timing-sensitive `buzz-acp` failures; the complete retry passed 905/905 in that package. - `cargo fmt --all -- --check` - `cargo clippy --workspace --all-targets -- -D warnings` - `just file-size-check` — 10/10 policy tests passed. - `just security-review-check` — 13/13 tests passed. - Push preflight — `push-head-scope`, `branch-skew`, `file-size-check`, `rust-tests`, and `desktop-tauri-checks` passed. - Blox Postgres relay lane — 84/84 at the byte-identical source patch; full live `e2e_relay` behavior matched the clean base (45 pass and the same pre-existing kind:9002 failure on each).

feat(relay): add early startup lifecycle logs (#7258)
## Why Early relay failures can currently appear as a container restart without a trustworthy in-process account of whether crypto, structured logging, configuration, relay identity, or the metrics listener failed. Most of those steps happen before the Prometheus exporter exists, so their chronology belongs in logs rather than metrics. Implements the logs-only early-startup slice of #7238. Post-bind Prometheus exporter supervision is tracked separately in #7284. ## What changed - create a process lifecycle recorder before the Tokio runtime and emit a fixed, versioned JSON schema directly to stderr; - record started and exactly one terminal event for `crypto_init`, `tracing_init`, `config_load`, `key_load`, `metrics_bind`, and the aggregate `process_telemetry` phase; - keep every status and reason bounded and suppress raw errors that could contain credentials, keys, URLs, or other secrets; - return typed metrics-install errors so `metrics_bind` can be classified without logging raw values, while preserving the existing public `metrics::install` API; - document the logs-only evidence contract and add real child-process regressions for success and failure paths. This PR adds **no startup metric families** and no dashboard contract. Existing application metrics remain unchanged. ## Verification Exact head: `8faf7526822a119efa035e58b2b3c59aa67fc81d` - `cargo fmt --all -- --check` - `cargo clippy -p buzz-relay --all-targets -- -D warnings` - relay binary target: 13 passed, 1 PostgreSQL-only test ignored - real relay child-process lifecycle target: 9 passed - full relay package library target: 1,023 passed, 89 ignored; the same six media tests failed at `crates/buzz-relay/src/api/media.rs:1145` with `Sqlx(PoolTimedOut)` because local PostgreSQL is unavailable - three independent exact-head reviews found no correctness, security, compatibility, lifecycle-accounting, logs-only-scope, or test-adequacy finding All exact-head GitHub CI gates are green, including lint, unit tests, PostgreSQL, relay/backend/desktop integration, both Linux server cross-compiles, Windows/macOS builds, and security checks. ## Staging verification - exact multi-architecture image: `dev-sha-8faf7526822a119efa035e58b2b3c59aa67fc81d-run-33708188952-1` - immutable manifest: `sha256:26cad28266a6bb0b0e7081eb6091d374e5489f8bb78c475a4a65737dee86cc67` - image workflow: https://github.com/block/buzz/actions/runs/33708188952 - focused staging deployment: https://github.com/squareup/builderbot-platform-core-infrastructure/pull/314 - replacement ReplicaSet `buzz-d68764bc7` has two Ready pods with zero restarts - Datadog received one complete, contiguous sequence 1-12 from each pod; both end with `process_telemetry/terminal/succeeded` at 3 ms - queries scoped to the replacement ReplicaSet return no data for the removed `buzz_startup_phase_terminal` or `buzz_startup_phase_duration_seconds` families The experimental Row 7 was removed from the Buzz Startup & Rollout Safety dashboard. This logs-only PR deliberately adds no replacement dashboard row. --- **Update Sep 3, 12:26 ET:** Clarified the review boundary: this PR does not close the broader #7238. Later exporter-task termination is pre-existing runtime behavior and is now explicitly tracked in #7284; no production code or staged image changed in this update.

perf(desktop): publish mention sends before waking agents (#7154)
## Summary Cuts perceived agent-mention send latency by publishing the message first and waking the agent afterwards, instead of blocking the send on a synchronous agent start/deploy round-trip. A send that mentions a stopped or undeployed managed agent now shows the message immediately; the wake runs fire-and-forget after the relay accepts the publish. The already-running-agent send also gets faster via revalidation dedupe and NIP-11 caching. ## Changes ### Publish-first agent wake - Wakes for mentioned managed agents are collected during send preparation and flushed fire-and-forget only after `await send(...)` resolves. No start can fire — and no "your message was sent" toast can appear — for a message the relay never accepted; every abort path (cancel, readiness error, publish rejection, dismissed non-member prompt) simply drops the queue. Persona-create wakes ride the pending draft behind the non-member prompt for the same reason. - Each wake is bound to the tenant scope captured at send time: the new `useDetachedAgentStart` hook passes `expectedRelayUrl` + `expectedSignerPubkey` with every start, so a wake that outlives a community switch fails closed at the backend instead of spawning against the new tenant. A wake whose scope has not resolved yet (identity query still loading, blank stored relay URL) is refused with a recoverable toast rather than fired unscoped. - In-flight wakes are deduped through a module-level map keyed by `(relay URL, pubkey)` — the same tenant pair the backend keys on — so two quick sends or two composers cannot double-spawn a cold agent during the seconds-long start window. Entries are deliberately retained across community switches (the key *is* the tenant scope, so a retained entry can never affect another community, and clearing it let an A→B→A round trip deploy a provider agent twice) and self-clean when the start settles. - Wake-failure toasts are fenced to the community they fired in via a module-level scope mirror: a start that settles after a community switch logs instead of rendering community A's failure over community B's UI, and an A→B→A return re-delivers the warning where it is actionable. - Membership attach and access-policy writes stay synchronous, so the harness's first kind-39002 read still sees the channel. ### Replay floor - The send timestamp travels with the wake as `BUZZ_ACP_REPLAY_FLOOR`, threaded through both local spawns (`spawn_agent_child`) and provider deploys (`deploy_to_provider` injects it into `launch.policy_env`), so the harness's startup watermark replays back past the just-published triggering message no matter how long the spawn takes. `buzz-acp` clamps the floor to `[now − 15min, now]`. - The floor is captured at enqueue time, not flush time — the flush runs post-publish, so a flush-time stamp could exceed the message's `created_at` and skip the very message the floor exists to cover. - On local spawns the caller's floor is asserted *after* the user env layering (and the ambient parent-process value is stripped unconditionally), so a saved persona/global/agent env entry cannot shadow this send's floor — mirroring the shadow-strip the provider path applies to `launch.env`. Both halves share one `REPLAY_FLOOR_ENV_VAR` const. ### Send-path latency reductions (already-running agents) - Mention revalidation is deduped: the publish-boundary pass reuses the pre-side-effect authorization pass unless an awaited round-trip actually separated the two (background upload, link-preview settlement, DM expansion, a real access-policy/membership write, or active-huddle enrollment). This preserves the #5681 authorization boundary while making the common send single-pass. - NIP-11 `self` lookups are cached per relay URL for 5 minutes. Only verified values are cached — non-2xx and malformed responses stay retryable — and URL keying keeps community switches from serving another relay's identity. - `applyReusableAgentAccessPolicy` now reports its relay write explicitly (`{ agent, wrote }`) instead of signalling through object identity, so the revalidation trigger above is load-bearing by construction. ### File splits Four files crossed the repository file-size ratchet during this work; one cohesive unit was extracted from each rather than raising a ceiling — `runtime/setup_payload.rs`, `commands/agents_create_fields.rs`, `app_state_accessors.rs`, and `useEnsureAgentMentionsReady.ts`. The ratchet is green at the tip. ### Review follow-ups The three concrete findings from the first review round are fixed at the tip: the pre-publish wake and its false "your message was sent" toast (fixed by queueing wakes behind the publish), the stale cross-community failure toast (fixed by the scope-mirror fence), and the A→B→A duplicate provider deploy (fixed by retaining the tenant-keyed in-flight entries across switches). The fast-path admission-staleness point is answered in the review thread: deferred paths already re-validate at the publish boundary, and the remaining fast-path window is milliseconds against an irreducible network-transit race. Mid-branch send-perf instrumentation was added to attribute the residual spinner latency and reverted once that analysis concluded — it is net-zero in this diff. ### Deferred follow-ups Durable mention catch-up via `event_mentions` (option 2 step 3) and backend deploy-epoch coalescing for the wake paths that do not funnel through `useDetachedAgentStart` (Agents-panel Start, restore, inbound-persona deploys) are intentionally left for separate changes. ## Testing - `cargo test --lib` on desktop/src-tauri: 3054 passed; clippy `-D warnings` + fmt clean - Desktop unit tests: 5856 passed (the 5 failures are the pre-existing `inboxReopenNavigation` / `useRetainedProjectGitViews` baseline, present on origin/main); `tsc --noEmit` and biome clean - Full mentions (87), channels (89), and community-rail (25) Playwright smoke suites against `pnpm build:e2e` bundles, with 3× stress reruns of each new spec - The load-bearing regression specs were confirmed red on the pre-fix code: publish-failure → zero starts and no false toast, the dedupe hold (1 call vs 2), the fail-closed scope refusal, the rail-switch toast fence, and the A→B→A retention spec (1 deploy vs 2) - New unit coverage pins the queue contract (enqueue-time floors, attach-seam queueing), the scope capture and verbatim relay-URL handoff, the dedupe map's keying and settle-then-repermit behavior, the unscoped refusal, the toast-scope mirror, the `{ agent, wrote }` contract, and the replay-floor env layering on both spawn paths 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Matt Toohey <contact@matttoohey.com> Co-authored-by: Claude Fable 5 <noreply@anthropic.com> |

feat(cli): add buzz gifs command group and NIP-30 emoji tags on messages (#7259)
## What Two new agent-facing capabilities in `buzz-cli`: ### 1. `buzz gifs` command group (agent KLIPY picker path) Agents can now search and share GIFs via the relay's authenticated KLIPY proxy without holding a provider credential. ```bash buzz gifs search # trending GIFs buzz gifs search --query "celebration" # search GIFs buzz gifs share --slug <slug> # report selection to provider Recents ``` Output is a JSON array of GIF objects. Paste the `cdn_url` field directly into `buzz messages send --content` — sending a GIF is a plain message containing the CDN URL, no special send-path handling. **Implementation details:** - Gates on NIP-11 `supported_extensions` containing `buzz-gif` and `gif.provider == "klipy"` - Uses relay-relative paths from the NIP-11 `gif` descriptor — no hardcoded paths; safe-path validation mirrors `desktop/src/features/gifs/api.ts` - New `post_json_authed` helper in `BuzzClient` handles NIP-98-signed JSON POSTs and 204 No Content responses - `customer_id` derived as `SHA-256(secret_key_bytes || '\0' || relay_url_bytes)[..16]` → 32 hex chars: stable, relay-scoped, not computable from public data, no storage needed - `locale` defaults to `$LANG` (stripped of encoding suffix) or `en_US` ### 2. NIP-30 custom emoji tags on outgoing messages `buzz messages send` now automatically attaches `["emoji", shortcode, url]` tags for any `:shortcode:` patterns in the content that resolve in the workspace palette — identical to the desktop composer behavior. ```bash buzz messages send --channel <uuid> --content "hello 👋 everyone 🎉" # → event carries ["emoji", "wave", "..."] and ["emoji", "tada", "..."] tags ``` **Implementation details:** - Hand-rolled single-pass scanner (no new dependency) implementing `:([a-z0-9_-]+):` case-insensitively with canonical lowercase output — mirrors `desktop/src/shared/lib/customEmojiTags.ts` exactly - Zero extra relay round-trips when content contains no `:` character; one `query` when candidates exist but none match - Palette fetch reuses the existing `union_custom_emoji` logic from `commands/emoji.rs` - `build_message` in `buzz-sdk` gains a new `emoji_tags: &[Vec<String>]` parameter (additive — all existing callers pass `&[]`); NIP-30 tag attachment lives in the SDK alongside `imeta` tags - MCP send path (`buzz-acp`) continues to pass `&[]` and is not affected; the MCP gap is noted in a comment ## Files changed | Crate | File | Change | |-------|------|--------| | `buzz-cli` | `src/commands/gifs.rs` | New — search + share handlers, NIP-11 gating, tests | | `buzz-cli` | `src/commands/mod.rs` | `pub mod gifs` | | `buzz-cli` | `src/lib.rs` | `Gifs(GifsCmd)` variant, dispatch arm, inventory test update | | `buzz-cli` | `src/client.rs` | `post_json_authed` helper | | `buzz-cli` | `src/commands/emoji.rs` | `scan_shortcodes` + `resolve_emoji_tags_for_content` + tests | | `buzz-cli` | `src/commands/messages.rs` | Emoji scan + tag injection in `cmd_send_message` + seam tests | | `buzz-cli` | `README.md` | `buzz gifs` section + emoji-in-messages note | | `buzz-sdk` | `src/builders.rs` | `build_message` gains `emoji_tags` param + tests | | `buzz-acp` | `src/pool.rs` | Update `build_message` call site (`&[]`) | | `buzz-acp` | `src/setup_mode.rs` | Update `build_message` call site (`&[]`) | | `countdown-bot` | `src/main.rs` | Update `build_message` call site (`&[]`) | Relates to: https://buzz.block.builderlab.xyz — buzz-team channel thread on agent GIF/emoji support --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> |

Add operation-aware database pool acquisition metrics (#7195)
## Why
Buzz already reports coarse writer/reader database checkout waits, but
those
signals cannot explain which startup or serving operation is blocked by
pool
pressure. That makes rollout diagnosis and postmortems ambiguous: a
readiness
probe, NIP-42 authentication, authorization check, reconnect history
repair,
event write, and background maintenance can all wait on the same pool
while
appearing identical.
This PR implements Package 2A of the pod-handoff plan: operation-aware
pool
borrow causality. It is observability-only; it does not change
configured pool
sizes, SQL semantics, transaction ordering, or timeout policy. Physical
DNS/TCP/TLS/Postgres authentication and session initialization remain
the
separate Package 2B boundary.
## Metric contract
The final contract separates three questions:
| Question | Metric |
|---|---|
| How long did checkout wait? |
`buzz_db_pool_acquire_duration_seconds{pool_role,operation}` |
| How did the attempt end? |
`buzz_db_pool_acquire_attempts_total{pool_role,operation,outcome}` |
| Who is waiting now for a tracked operation? |
`buzz_db_pool_waiters{pool_role,operation}` |
Outcomes are `success`, `timeout`, `error`, and `cancelled`. Operations
are
`bootstrap`, `readiness`, `tenant_resolution`, `authentication`,
`authorization`, `subscription_history`, `event_write`, and
`maintenance`.
Only these eleven pool/operation pairs are constructible:
```text
writer/bootstrap reader/bootstrap
writer/readiness
writer/tenant_resolution
writer/authentication
writer/authorization reader/authorization
writer/subscription_history reader/subscription_history
writer/event_write
writer/maintenance
```
The duration histogram intentionally does not carry `outcome`. Result
data
remains available on the terminal counter for historical counts and
rates,
without multiplying the expensive histogram family. Nine finite buckets
plus
`+Inf`, sum, and count produce 12 duration series per valid pair.
Together with
four outcome counters and one waiter gauge, the new-family ceiling is
exactly
187 raw Prometheus series per pod, asserted from the production
exporter.
The existing coarse acquisition families remain temporarily for
dashboard
compatibility while the new series are validated in staging.
The operation-specific waiter family covers the explicitly routed,
deployment-critical operations above; it is not a census of every
possible
SQLx checkout in the process. The dashboard pairs it with SQLx pool
active/idle/max gauges for whole-pool capacity context, and treats a
missing
operation series as unknown rather than healthy zero.
## What changed
### Cancellation-safe acquisition ownership
- Add writer- and reader-specific typed operation APIs so invalid label
pairs
cannot be constructed and store modules cannot emit reader labels.
- Own every polled acquisition with one RAII terminal guard.
- Record exactly one duration and terminal outcome for success, timeout,
error,
or cancellation.
- Emit nothing for a future that is created but never polled.
- Balance the operation-specific waiter count exactly once on every
terminal or
dropped future.
- Periodically refresh every expected waiter pair, including healthy
zero, so
missing telemetry is not presented as zero. Reader pairs are emitted
only
when a distinct read pool is configured; a writer-only pod cannot
fabricate
healthy reader-zero state.
### Production attribution
Route the deployment-critical acquisition paths through caller-owned
semantic
entry points, including:
- writer and reader bootstrap;
- the real post-#7149 readiness acquisition and deletion-catalog
validation;
- tenant resolution and community lifecycle checks;
- NIP-42 allowlist authentication;
- membership, moderation, invite, operator, Git, agent-owner, and policy
authorization;
- operator community create/list/archive/unarchive, reverse host/channel
tenant
resolution, and REQ row-community conformance lookups;
- writer/reader subscription history, feed, thread, and routed fallback
paths;
- primary and command event writes, replaceable events, mention
indexing,
reaction/channel/member/archive side effects, and thread metadata;
- push matching, usage rollups/leadership, replica-fence startup and
recurring
probes, periodic reconciliation, channel/deletion reapers, partitions,
and
other bounded maintenance/bootstrap paths.
Shared helpers now accept caller-owned intent or expose named semantic
variants
instead of assigning one misleading operation to every caller. No known
P0 path
uses `other`.
### Readiness and size-one-pool correctness
- Rebase on the post-#7149 readiness implementation and instrument the
actual
`Db::readiness_check` acquisition rather than the superseded ping-only
seam.
- Acquire once for deletion-catalog validation and run its queries on
that
connection, preserving the shared readiness deadline.
- Scope the channel-roster catalog checkout before the behavior probe so
a
size-one writer pool cannot self-deadlock during startup verification.
### Exporter, documentation, and CI
- Register metric HELP/type/unit metadata through the production
Prometheus
builder.
- Configure dedicated checkout buckets at 1ms, 5ms, 10ms, 25ms, 50ms,
150ms,
500ms, 1s, and 3s.
- Add a production scrape-contract test for exact names, labels,
buckets,
valid pairs, sensitive-label exclusion, and the 187-series ceiling.
- Add source mutation guards for the P0 semantic entry points and
raw-checkout
bypasses.
- Add an exact backend-integration CI selector for the production
attribution,
cancellation, readiness, and size-one-pool PostgreSQL tests.
- Document the frozen label vocabulary, valid combinations, semantics,
and
cardinality budget in the Helm chart README.
## Dashboard intent
The new Stage 2 row in **Buzz Startup & Rollout Safety** is
deployment-first:
- baseline-versus-candidate attempts, failure rates, cancellation rates,
and
maximum wait by operation;
- outcome counts and percentages over time by SHA/ReplicaSet;
- acquisition wait heatmap, average, and maximum through the rollout;
- historical waiter pressure beside writer active/idle/max context;
- per-pod postmortem drilldown, including terminated pods;
- a smaller current-waiter table with explicit stale/missing semantics.
Percentile widgets remain disabled until Datadog metadata confirms
percentile
support for the new distribution. Current gauges use no fill,
interpolation, or
`default_zero`; missing means unknown.
## Risk assessment
Moderate. The patch touches many database acquisition call sites, but
preserves
the selected physical pool and executes the same SQL on the acquired
connection. The main risks are incorrect semantic attribution,
cancellation
double-counting, and a helper accidentally acquiring twice. Typed APIs,
production-method PostgreSQL tests, source guards, the raw scrape
contract, and
the size-one-pool regression cover those risks.
No tenant, community, user, pubkey, event, channel, SQL, URL, pod,
version,
ReplicaSet, or request-controlled value is emitted as an application
metric
label. Deployment identity is supplied by infrastructure enrichment.

chore(db): drop Phase-A NIP-FI relay-side authority ledger (#7221)
Removes the dead relay-side authority ledger introduced by migrations 0041 and 0042, and the dead `require_attested_key` verifier knob from `buzz-auth`. Both are unreachable by design under NIP-FI spec v2 (#7214, squash `d4420eb47`), which makes OSS Buzz stateless for identity: the relay neither stores nor verifies an authority chain. ## What changes **`migrations/0044_drop_nip_fi_ledger.sql`** Drops all fifteen NIP-FI ledger tables and their trigger functions using `CASCADE` to resolve the circular deferred FK between `identity_bindings` and `identity_lifecycle_history`. Drops proceed in FK dependency order: selectors → history/bindings → enrollment_policies/receipts → parallel drop of auth tables. Restores `community_write_fence_excluded_table` to its pre-0041 body (removes NIP-FI table names from the exclusion array). **`schema/schema.sql`** Removes the NIP-FI section (~1885 lines of tables, functions, and triggers) and updates `community_write_fence_excluded_table` to match. **`crates/buzz-db/src/runtime/migration.rs`** - Updates the `embedded_migrator_contains_consolidated_initial_schema` sanity check: count 43→44, adds 0044 assertion block (verifies `DROP TABLE` statements and absence of NIP-FI names from `schema.sql`). - Removes ~2580 lines of NIP-FI Postgres integration tests (all `#[tokio::test] #[ignore = "requires Postgres"]` from the 0041/0042 behavioral coverage). - Removes the `extract_excluded_table_array` drift check (0042 body no longer matches `schema.sql` by design). - Adds `migration_0044_drops_populated_nip_fi_ledger_cleanly`: runs migrations to 0042, seeds rows in `authorization_operation_receipts` and `authorization_invalidation_domains`, then runs to 0044 and verifies all fifteen NIP-FI tables are absent. **`crates/buzz-auth/src/nip_fi/config.rs`** Removes `require_attested_key: bool` from `IssuerPolicy` — field, constructor parameter, accessor, and its contribution to `derive_assertion_policy_id`. **`crates/buzz-auth/src/nip_fi/verifier.rs`** `parse_nostr_pubkey_claim` no longer takes a `policy` parameter. The `None` (absent claim) arm now returns `Err(VerifierError::ClaimRejected)` unconditionally instead of conditionally on `policy.require_attested_key()`. **`crates/buzz-auth/src/nip_fi/verifier/tests.rs`** - Removes `missing_nostr_pubkey_denies_under_attested_key_policy` (the sole `require_attested_key: true` call site). - Removes `false,` from all eleven `IssuerPolicy::new` call sites. - Injects `nostr_pubkey` by default in `mint_signed_by` (spec v2 requires it unconditionally). - Updates `valid_access_token_verifies` to assert `asserted_key().is_some()`. **`crates/buzz-auth/src/nip_fi/startup/tests.rs` + `jwks/tests.rs`** Removes `false,` from all `IssuerPolicy::new` call sites and adds `nostr_pubkey` to all token-minting helpers. ## Verification - Fresh-DB migration run to head: all migrations apply cleanly in sequence. - Populated-0041/0042-DB migration through 0044: seeds rows in live NIP-FI tables, verifies all fifteen are dropped without error. Closes the dead-code inventory item from the spec-v2 cleanup plan (channel `48374f48`).

feat(relay): add detailed readiness metrics (#7149)
## Summary
This PR makes relay readiness failures diagnosable without weakening the
existing fail-closed readiness contract. It distinguishes Postgres pool
acquisition from query execution, Redis pool acquisition,
deletion-catalog validation, and the overall two-second deadline;
exports a bounded Prometheus contract for rollout dashboards; and fixes
the concurrency, shutdown, and listener-boundary semantics needed for
those signals to be trustworthy.
## Why
The previous `/_readiness` implementation exposed only an aggregate
ready/not-ready result. During a rollout, operators could not tell
whether a pod was blocked on:
- acquiring a Postgres connection;
- executing the Postgres readiness query;
- acquiring a Redis connection;
- validating the deletion catalog; or
- the shared readiness deadline.
Adding metrics to the existing handler also exposed three correctness
hazards that this PR resolves:
1. the same handler is mounted on both the public application listener
and the private Kubernetes health listener, so public requests could
otherwise distort rollout telemetry;
2. concurrent probes can finish out of order, allowing an older result
to overwrite newer current-state gauges; and
3. a probe started before SIGTERM can finish afterward, incorrectly
return `200 ready`, and resurrect ready gauges while the process is
draining.
## Behavior
### Readiness evaluation
- Postgres, Redis, and deletion-catalog checks still run under one
shared two-second deadline.
- Postgres distinguishes pool acquisition timeout/error from query
timeout/error.
- Redis distinguishes pool acquisition timeout/error. This does not
claim a Redis command round trip.
- The deletion catalog distinguishes operation timeout/error.
- Multiple failures are reported as `multiple_dependencies_failed`;
exhaustion of the shared deadline is reported as `overall_timeout` when
no more specific completed outcome wins.
- Readiness remains fail-closed: every dependency must succeed for `200
{"status":"ready"}`.
### Ordered publication and shutdown
`ReadinessCoordinator` is process-owned and uses one mutex as the
linearization point for probe generations, current-state publication,
and terminal shutdown.
- Every completed dependency attempt may contribute its truthful counter
and duration observation.
- Only the newest admissible probe generation may publish current-state
gauges.
- An older, slower probe cannot overwrite a newer probe's gauges.
- `begin_shutdown()` and probe commit serialize through the same
coordinator.
- Once shutdown commits, an in-flight probe cannot return ready or
publish ready/current dependency gauges, even if its dependency work
later succeeds.
Shutdown without dependency evaluation records only:
- `buzz_readiness_checks_total{reason="shutting_down"}`; and
- `buzz_readiness_state{check="overall"} = 0`.
It does **not** fabricate dependency failures, dependency state changes,
or zero-duration latency samples. If shutdown wins after an in-flight
evaluation actually ran, those completed dependency attempts may remain
as attempt telemetry, but they cannot overwrite shutdown-dominant
current state.
### Listener and response contract
- The private health listener's `/_readiness` route is the sole
authority for rollout readiness telemetry.
- The public application listener retains `/_readiness` for
compatibility, evaluates the same dependencies, and preserves the
existing response shape, but it emits no `buzz_readiness_*` metrics.
- Ready responses remain `200 {"status":"ready"}`.
- Shutdown responses remain `503 {"status":"shutting_down"}`.
- Failed private-health responses include the bounded `reason` plus
`postgres`, `redis`, and `deletion_catalog` booleans.
- Failed public compatibility responses retain the dependency booleans
but omit the new detailed reason.
- No header, query parameter, path value, or other request-controlled
value becomes a metric label.
## Prometheus contract
The final schema is intentionally capped at **99 raw Prometheus series
per pod**.
| Metric | Type | Labels | Raw series/pod |
|---|---|---|---:|
| `buzz_readiness_checks_total` | counter | `reason` | 12 |
| `buzz_readiness_dependency_checks_total` | counter | `dependency`,
typed `outcome` | 11 |
| `buzz_readiness_check_duration_seconds` | histogram | `check` | 72 |
| `buzz_readiness_state` | gauge | `check` | 4 |
| **Total** | | | **99** |
### Closed label sets
`reason`:
```text
ready
shutting_down
postgres_pool_timeout
postgres_pool_error
postgres_query_timeout
postgres_query_error
redis_pool_timeout
redis_pool_error
deletion_catalog_timeout
deletion_catalog_error
overall_timeout
multiple_dependencies_failed
```
Valid `dependency` / `outcome` pairs are enforced by typed enums:
- `postgres`: `success | pool_timeout | pool_error | operation_timeout |
operation_error`
- `redis`: `success | pool_timeout | pool_error`
- `deletion_catalog`: `success | operation_timeout | operation_error`
`check` is `overall | postgres | redis | deletion_catalog`.
The readiness histogram has 15 configured buckets concentrated around
the two-second deadline:
```text
0.001, 0.005, 0.01, 0.025, 0.05, 0.1, 0.25, 0.5,
0.75, 1.0, 1.25, 1.5, 1.75, 2.0, 2.5, +Inf
```
The contract deliberately removes the redundant overall `result` label
and the histogram `outcome` label. Pod, ReplicaSet, version, rollout,
raw error, SQL, URL, tenant, user, community, pubkey, and
request-controlled values are prohibited application labels;
infrastructure enrichment can supply deployment identity outside the
application metric.
## Postgres production seam and CI
The real `Db::readiness_check` path now supports deterministic
production-seam testing while preserving the same acquisition/query
implementation used by the relay. The isolated PostgreSQL lane
automatically discovers and executes three ignored integration tests
covering:
- a held sole connection causing pool timeout, followed by recovery
after release;
- closed-pool acquisition error;
- acquisition success followed by query timeout;
- classified query error;
- cancellation while waiting for a connection;
- cancellation during an in-flight query; and
- eventual pool recovery with waiter/in-flight state balanced.
This prevents the central SQLx/Postgres behavior from being merely
compiled but never executed in CI.
## Tests and verification
- `cargo fmt --all -- --check`
- `./scripts/test-postgres-test-discovery.sh`
- complete `cargo test -p buzz-db`
- focused `cargo test -p buzz-relay readiness`
- real-router `cargo test -p buzz-relay real_health_route_`
- controlled PostgreSQL execution of all three ignored readiness tests
- production health router -> real `GET /_readiness` -> Prometheus
render assertions
- public-router requests proving zero rollout telemetry
- deterministic out-of-order A/B probe tests
- SIGTERM-during-probe tests proving shutdown dominance
- exported metric name/type/exact-label/bucket assertions
- exported raw-series allowlist and 99-series ceiling assertion
The route-to-scrape regression test uses the production Prometheus
builder and verifies the `2`, `2.5`, and `+Inf` readiness buckets. It
fails if the health recording call, health route, public/health
boundary, generation fence, shutdown fence, or bucket override is
removed.
## Risk assessment
**Medium.** This changes the live readiness publication path and adds
synchronization around probe commit/shutdown. The risk is bounded by:
- preserving the existing dependencies and shared two-second deadline;
- keeping readiness fail-closed;
- using a short, process-local mutex only at begin/commit linearization
points, not across dependency awaits;
- retaining the public compatibility endpoint while isolating its
telemetry;
- enforcing typed, low-cardinality labels and an exported series
ceiling; and
- covering the production router, Prometheus exposition, real PostgreSQL
seam, concurrency ordering, and shutdown races.
## Operational notes
- Dashboards should treat `buzz_readiness_state` as the latest sampled
current state, not as an event stream.
- `shutting_down` should be excluded from dependency-failure alerts
because no dependency failure is implied.
- Do not use `default_zero()` for missing current-state data;
missing/stale is unknown, not healthy.
- Use histogram buckets, heatmaps, max, or average until the Datadog
distribution metadata confirms percentiles are enabled; do not title a
widget p95 before that live readback.
## Non-goals
This PR does not add the broader process-startup lifecycle,
worker/listener supervision, shutdown coordinator, WebSocket/huddle
handoff, client recovery telemetry, dashboard mutations, Datadog
configuration changes, or deployment changes. Those remain separate
follow-up work.

feat(buzz-agent): add DatabricksAuthCoordinator single-flight OAuth (#5545)
## What
Consolidates all Databricks OAuth acquisition behind one coordinator on
`PkceOAuthTokenSource`. Every entry point — the four `TokenSource`
methods (`bearer`, `bearer_no_browser`, `refresh_now`,
`interactive_login`) plus the public `acquire_with_intent` — routes
through a single `acquire()`/`acquire_locked()` core that owns browser
and cooldown policy.
Before this, acquisition logic was scattered across those methods with
no coordination: concurrent callers (Desktop discovery, the saved-agent
model picker, managed-runtime inference) could each pop their own
browser, and a just-denied attempt would immediately re-prompt on the
next passive read.
## How
- **Intent policy.** `AuthIntent::{Auto, UserInitiated, Headless}`
decides whether a caller may open a browser and whether it honors the
cooldown. `Headless` never browses; `Auto` browses but honors an
unexpired cooldown; `UserInitiated` browses and bypasses+clears the
cooldown.
- **Two-layer single-flight per cache key.** An in-process registry
(`INFLIGHT`) coalesces same-key, same-intent callers onto one leader's
attempt before the file lock. The slot key is `(lock_path, AuthIntent)`,
so a `UserInitiated` sign-in never inherits an `Auto` leader's result. A
joined result is revalidated against the waiter's own contract. Across
processes, callers serialize on a `flock`-based advisory lock and share
success through the on-disk cache. RAII `Drop` releases both lock and
leader slot.
- **Joiner credential-state reconciliation.** `SlotPublish` carries the
full `CachedToken` on success. Each joiner reconciles its own
independent `state` cell under `state.lock().await` before returning:
adopt when absent, expired, or matching the joiner's rejected
credential; preserve any distinct newer usable credential. On a matching
shared failure, neutralize the joiner's in-memory rejected entry under
lock via `expire_rejected_memory` — durable disk mutation is reserved
for `acquire_locked` under the cross-process file lock. Without this, a
joining source's state remains stale or empty and subsequent plain
`bearer()` calls resurface the rejected or absent credential.
- **Validate-before-persist boundary.** `finish()` is the
candidate-token persistence boundary for refresh and browser results.
Before a token is written to cache or the cooldown is cleared, a bearer
equal to the caller's rejected bytes yields a typed failure.
- **Token neutralization.** When `acquire_locked` enters with `rejected
= Some(bytes)`, it calls `expire_rejected()` under the state lock before
any cache check.
- **Cross-process failure single-flight.** An `AttemptRecord` sidecar
records a monotonically-increasing generation, intent, result code, and
SHA-256 digest of the completing caller's rejected token. Adoption is
temporal (pre-queue snapshot predates current generation) and
digest-matched.
- **Typed outcomes.** `AuthError` with stable `code()`/`from_code()`
replaces display-text matching.
- **Durable cooldown sidecar.** Every failed browser attempt is recorded
next to the cache key. 5-minute expiry.
- **Windows disk persistence disabled.** On non-Unix platforms,
`persist()` is a no-op. Lock, cooldown, and attempt sidecars are active
on all platforms. Tests that seed or assert on the on-disk token cache
are `#[cfg(unix)]`-gated.
- **Injected browser opener** invoked while the localhost callback
listener is live.
## Tests
- `crates/buzz-agent/tests/databricks_auth_coordinator.rs`:
browser/cooldown/classification acceptance matrix with a scripted
`BrowserOpener` and stub OIDC provider. P1 regressions exercise the full
`finish()` → `acquire_locked()` → `acquire_leader()` →
`LeaderGuard::complete()` → joiner wiring:
- `test_inprocess_joiner_reconciles_stale_state_after_shared_success`
(Unix): two real sources both loaded locally-fresh-but-rejected X; after
shared success Y, subsequent plain `bearer()` on both returns Y, not X.
-
`test_inprocess_joiner_neutralizes_rejected_on_matching_shared_failure`
(Unix): B's matching rejected X is force-expired in memory after shared
`RefreshRejected`; subsequent read cannot return X.
- `test_inprocess_joiner_populates_empty_state_no_second_acquisition`
(non-Unix): empty A/B join a browser success; B's subsequent headless
read returns Y without a second browser (no disk fallback on non-Unix
exposes the regression).
- `test_crossprocess_userinitiated_waiter_adopts_predecessor_denial`
(snapshot-marker barrier replacing an earlier sleep for deterministic
generation ordering).
- `auth.rs` in-crate tests: lock-primitive edges, disk-recheck on shared
failure (`#[cfg(unix)]`), and:
- `test_joiner_reconciliation_blocked_until_state_lock_released`:
deterministic direct-poll proof that awaited reconciliation requires
`state.lock().await`. The test task holds B's state mutex and manually
polls a pinned real `acquire()` future — Poll 2 (slot published, mutex
still held) must return `Pending` because `lock().await` blocks; with
`try_lock` instead, Poll 2 returns `Ready`, failing the assertion.
- `test_joiner_preserve_distinct_newer_credential`: deterministic direct
polling parks B at `slot.wait()`, then writes Z directly into B's state
in the same task, then publishes Y and awaits completion. B must return
Y but leave state == Z. Mutation check: unconditional adoption
overwrites Z with Y, failing the state assertion.
- `test_joiner_shared_failure_recovers_disk_replacement` (Unix): the
matching-failure joiner enters the recovery branch — after
`expire_rejected_memory` (in-memory, empty state no-op) it reads a
sibling-written disk replacement via `usable_from_disk` and returns it.
Mutation check: removing the `usable_from_disk` recovery branch returns
`Err(RefreshRejected)`.
- `test_joiner_failure_does_not_write_disk` (Unix): byte-for-byte
disk-invariance regression — a matching-failure joiner calls
`expire_rejected_memory` and must not touch the on-disk cache. An
independent process C may write a valid replacement between A's failure
and B's reconciliation; this guard ensures B's unfenced in-memory
neutralization cannot overwrite C's concurrent disk write. Mutation
check: reverting to `expire_rejected` rewrites the file (`expires_at =
0`), changing the bytes and failing the assertion.
- `test_lock_timeout_leaves_cooldown_sidecar_byte_for_byte_untouched`: a
waiter past its deadline returns `LockTimeout` before entering
`acquire_locked`; the cooldown sidecar bytes are unchanged. Documents a
pre-lock limitation: `LockTimeout` callers do not neutralize state or
sidecars.
## Scope / follow-ups
- **Runtime 401 handling is deferred.** This PR owns acquisition
single-flight and policy.
- **Desktop wiring is Phase 2** (not in this PR's boundary). Confined to
`crates/buzz-agent/`.
- **Windows DACL** is a follow-up once the `windows-sys` binding is
available.

fix(dev-mcp): extend shell timeout cap to 20 minutes and align outer budgets (#7185)
Raise the `buzz-dev-mcp` shell timeout ceiling to 1,200,000 ms (20 minutes) while keeping the omitted-value default at 120,000 ms (2 minutes), and align the two outer timeout layers that bound every MCP tool call. ## What changed **`crates/buzz-dev-mcp`** — shell timeout cap raised to 1,200,000 ms; tool and parameter descriptions updated to match. **`crates/buzz-agent`** — `BUZZ_AGENT_TOOL_TIMEOUT_SECS` default raised from 660 s to 1,260 s (20-min cap + 60 s cleanup headroom). The old 660 s default would have killed the MCP server at 11 min, before a 20-min shell call could finish. README updated. **`crates/buzz-acp`** — `DEFAULT_IDLE_TIMEOUT_SECS` raised from 900 s to 1,500 s and its doc comment updated (1,200 s max shell + 300 s breathing room). The old value was documented as "600 s max shell + 300 s" — stale arithmetic. ## Tests - Existing boundary tests in `buzz-dev-mcp` (default, exact-cap, over-cap, `u64::MAX`) all pass. - `default_idle_timeout_is_1500_seconds` — pinned constant replaces old 900 s assertion. - `default_tool_timeout_is_1260_seconds` — new pinned constant in `buzz-agent`. - `budget_ordering_invariant_shell_cap_plus_headroom_fits_within_idle_timeout` — new const assertion in `buzz-acp` that encodes the full three-layer ordering: shell cap (1,200 s) ≤ agent tool timeout (1,260 s) < ACP idle timeout (1,500 s) < max turn duration. A future edit that inverts any tier fails to compile. --------- Signed-off-by: Alia <d32955ad69077062930cc46cfe2df30ca9aaf6f8e76422681265e9e9af704d78@buzz.block.builderlab.xyz> Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Co-authored-by: Alia <d32955ad69077062930cc46cfe2df30ca9aaf6f8e76422681265e9e9af704d78@buzz.block.builderlab.xyz> Co-authored-by: Hayt <9e1c23a3fd83f61da34420e4e88ff1b16e45cafcc0cd9019eb07d4ecfa8ca9b0@buzz.block.builderlab.xyz> |

feat(buzz-auth): add production NIP-FI federated assertion runtime (#7109)

Stack: PR 2 #6994 (merged) → this PR (#7109) → PR 4 #7148 → PR 5 ## What Production assertion runtime for NIP-FI Phase A: JWKS caching layer, SSRF-hardened HTTP fetcher, startup validation gate, NIP-11 discovery serialization, federated assertion verifier with sealed key-source authority, and supporting invariant tests. ## Changes ### `crates/buzz-auth/src/nip_fi/jwks/` `ProductionJwksSource<F>` implements the sealed `IssuerKeySource` trait: - `HttpJwksFetcher`: reqwest-backed fetch with SSRF protection — URI validation (HTTPS, no credentials, no fragment, no host matched by the shared enumerated deny policy), per-fetch DNS resolution rejecting any resolved address matched by the shared enumerated deny policy, address pinning to prevent DNS rebinding TOCTOU, redirect denial, incremental body streaming capped at 512 KiB before any parse - IPv6 host extraction via typed `Url::host()` accessor (strips brackets before SSRF check and provides the correct bare input form for reqwest `resolve()` pinning; the bracketed form from `host_str()` fails `IpAddr::parse` and does not match the URL authority key) - Complete-operation deadline via `tokio::time::timeout` covering DNS resolution through body streaming - Bounded periodic refresh with configurable interval and hard snapshot deadline - Cancellation-safe RAII refresh permit: dropped on future cancellation so the next caller can re-fetch - Content-digest-gated generation counter: identical re-fetches preserve generation; key rotations advance it - Injectable clock (`now_fn: Arc<dyn Fn() -> DateTime<Utc> + Send + Sync>`): production uses `Arc::new(Utc::now)`; all four deadline creation and expiry checks use `(self.now_fn)()`, enabling controlled-time testing without wall-clock sleep `JwksSourceContract`: a closed value type that is the single source of truth for the three deployment fields whose change alters which keys the runtime trusts and how long it trusts them: - `jwks_uri` — selects the authenticated key source; validated at construction (HTTPS, no credentials/fragment, no bare private-IP host); stored as the `Url`-normalized form so that equivalent spellings (uppercase host, explicit default port `:443`, dot-segment paths like `/.well-known/./jwks.json`) converge to the same `AssertionPolicyId` - `refresh_interval_seconds` — defines bounded refresh behavior; positive, ≤ 1 year, strictly < `key_snapshot_hard_deadline_seconds` - `key_snapshot_hard_deadline_seconds` — defines the source's accepted time rule; every `VerifiedAssertion.revalidation_dependencies` deadline derives from this `JwksSourceContract` is a required `IssuerPolicy` input and is included in `derive_assertion_policy_id` after a domain separator. `IssuerJwksConfig` embeds the contract instead of independently restating these fields — startup validation rejects any contract mismatch (`NipFiStartupError::JwksContractMismatch`). ### `crates/buzz-auth/src/nip_fi/verifier.rs` - `FederatedAssertionVerifier<S>`: provider-neutral verifier over a closed multi-issuer registry and sealed `IssuerKeySource` - `Arc<S>: IssuerKeySource` forwarding impl (blanket seal for `Arc<S>` in the sealed module) — one `Arc<ProductionJwksSource>` can be shared across multiple verifiers; all observe JWKS refreshes through the shared cache without rebuilding the verifier - `AssertionKeySet`: crate-private constructor seals issuer binding — no external crate can relabel issuer B's JWKS as issuer A - Sealed `IssuerKeySource` trait closes the authority-construction seam at both ends ### `crates/buzz-core/src/network.rs` Renamed `is_private_ip` to `is_not_global_unicast` (compat alias retained) and restored the complete IANA deny/exception table from this branch's own history (`272dacadb`). The predicate is an enumerated deny/explicit exception policy: addresses covered by a named deny rule are rejected; addresses not covered by any explicit deny rule (e.g. `fe00::1`) pass through. Deny rules are derived from the IANA Special-Purpose Address Space registries (last updated 2025-10-09), with globally-reachable exceptions carved out explicitly (e.g. PCP/TURN anycast inside 2001::/23). Blocked IPv4 classes: loopback (127/8), private RFC 1918 (10/8, 172.16/12, 192.168/16), link-local (169.254/16), unspecified (0/8), broadcast, CGNAT/RFC 6598 (100.64/10), benchmarking/RFC 2544 (198.18/15), IETF Protocol Assignments (192.0.0.0/24, globally reachable exceptions: 192.0.0.9 PCP anycast RFC 7723 and 192.0.0.10 TURN anycast RFC 8155), documentation/RFC 5737 (192.0.2/24, 198.51.100/24, 203.0.113/24), deprecated 6to4 relay anycast (192.88.99.0/24, RFC 7526, global=None → conservative deny), multicast/RFC 5771 (224/4), reserved class-E (240/4). Blocked IPv6 classes: loopback (::1), unspecified (::), ULA (fc00::/7), link-local (fe80::/10), deprecated site-local (fec0::/10, RFC 3879), multicast (ff00::/8), IETF Protocol Assignments envelope (2001::/23, globally reachable exceptions: 2001:1::1–::3 PCP/TURN/DNS-SD anycast, 2001:3::/32 AMT RFC 7450, 2001:4:112::/48 AS112-v6 RFC 7535, 2001:20::/28 ORCHIDv2 RFC 7343, 2001:30::/28 DETs RFC 9374), documentation (2001:db8::/32 RFC 3849, 3fff::/20 RFC 9637), 6to4 (2002::/16, RFC 3056), Discard-Only (100::/64, RFC 6666), Dummy IPv6 Prefix (100:0:0:1::/64, RFC 9780), SRv6 SIDs (5f00::/16, RFC 9252), NAT64 local-use (64:ff9b:1::/48, RFC 8215). IPv4 embedded in mapped, compatible, NAT64 well-known (64:ff9b::/96), and SIIT IPv4-translated (::ffff:0:0:0/96) forms is checked recursively. All three callers (JWKS boundary, webhook SSRF, link-preview SSRF) inherit the complete predicate through the inline `is_private_ip` compatibility alias. ### Invariant coverage **Canonical URI convergence.** `jwks_contract_uri_canonicalization_convergence_and_divergence` asserts that uppercase host, explicit `:443`, and dot-segment path (`/.well-known/./jwks.json`) each produce the same `AssertionPolicyId` as the canonical form; a genuinely different host or path diverges. Mutation: storing raw input bytes instead of `parsed.to_string()` turns the three convergence assertions red. **Resolved-target and pin-input seam.** `resolved_target_and_pin_key_seam_public_ipv6_and_fec0_rejection` carries a public `2606:4700::1` URI through all three stages of `fetch_jwks_inner`: `extract_url_host_and_port` yields the bare host (no brackets), `resolve_and_check_ssrf` takes the IP-literal fast path and returns the accepted `IpAddr`, and the extracted host string equals the URL authority form (verifying the correct bare input to reqwest's `resolve()` pin call). `fec0::1` traverses the same extraction and SSRF stages and is rejected as `InvalidUri`. Network-free: both addresses are IP literals with no DNS lookup. Mutation: restoring `host_str()` brackets the address, `IpAddr::parse` fails, the SSRF fast path is unreachable, and all three assertions flip red. **Controlled original-deadline rotation.** `shared_arc_source_verifier_rejects_expired_a1_accepts_a2` uses an `AtomicI64`-backed injectable clock to advance past A1's original absolute deadline without wall-clock sleep. A1's deadline is computed at T0 and never mutated. The clock advances to T0 + HARD_DEADLINE_SECS + 1; `get_snapshot` fires a re-fetch and installs A2. One unchanged `FederatedAssertionVerifier` then rejects A1-signed tokens (deadline enforced by the `key_set` read path) and accepts A2-signed tokens, proves A2's generation is strictly greater, and confirms A2's deadline is later than A1's original. Mutation oracle: replace the shared `Arc` with an independently constructed source built from the same configs and sharing the same controlled clock, warmed with a separate A1 fetch before advancement. Post-advancement, `key_set()` on the verifier's independent source filters the expired A1 snapshot (`filter(|c| now < c.hard_deadline)`) and returns no keys — the verifier never re-fetches and never observes A2. A1-reject stays green (the independent cache is also expired, so no A1 keys are served), but A2-accept flips red, because the verifier never observes A2. A2 acceptance is the reliable shared-source oracle. **Complete SSRF classifier boundary.** JWKS-boundary tests cover every newly restored class through `validate_jwks_uri` (URI-validation path): `192.0.0.1` (IETF Protocol Assignments interior), `192.0.0.9`/`.10` (PCP/TURN anycast global exceptions), `192.88.99.1` (deprecated 6to4 anycast), `2001:2::1` (2001::/23 interior), `2001:1::1` (2001::/23 global exception), `100::1` (Discard-Only), `3fff::1` (documentation), and `5f00::1` (SRv6 SIDs). URI validation and resolved-target enforcement share the same `is_not_global_unicast` predicate, so these URI-path tests exercise the complete classifier table. All pass mutation: removing any deny branch makes the rejection assertion red; removing any exception branch makes the acceptance assertion red. The resolved-target enforcement path is covered separately by `resolved_target_and_pin_key_seam_public_ipv6_and_fec0_rejection` for `::1` (loopback), public `2606:4700::1`, and `fec0::1`. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: Cea Stapleton Cordasco <261786559+cea@users.noreply.github.com> |

ci: run PostgreSQL tests in isolated lane (#6730)
## Why PR #6660 introduced four PostgreSQL-backed persistence tests and a focused CI selector, but an exact test-name list does not automatically cover future database tests. Broad ignored-test execution also exposed shared-schema races and ambiguity between desired-state and migration-applied schema expectations. ## What - Establish a discoverable convention: PostgreSQL unit modules use `postgres_tests`, PostgreSQL integration binaries use a `postgres_` prefix, and unrelated external-infrastructure tests use an `external_infra_` prefix. - Add a dedicated nextest PostgreSQL profile and archive-backed CI job covering the relevant crates without enumerating test names. - Create a run-scoped desired-state source database and a unique PostgreSQL database per test process for parallel-safe isolation, with cleanup on success, failure, or interruption. - Route destructive migration and migration-parity tests to clean `template0` databases while desired-state tests clone the desired-state database. - Document discovery, schema modes, required role privileges, and a bounded portable local runner. - Keep the existing infrastructure-free unit-test jobs unchanged. This is intentionally limited to test and CI harness behavior. It does not move production database code, change persistence semantics, or implement issue #20's broader shared test-utility refactor. ## Risk Low production risk because all changes are confined to tests, CI configuration, documentation, and test harness scripts. Remaining operational risks: - Cleanup retries `dropdb --force` five times across roughly four seconds. Exhaustion warns with the database name but deliberately does not mask the test result; individual PostgreSQL diagnostics are suppressed. - The seven-package boundary is duplicated between the runner and CI archive and must remain synchronized if PostgreSQL tests move to a new crate. - Portable SHA fallback branches were exercised on Linux; no macOS Blox workstation was needed for this Linux CI artifact. - GitHub's unchanged generic Unit Tests job currently fails while cold-linking `buzz-voice` because `sherpa-onnx-c-api` is absent. The branch changes no voice/build/toolchain inputs; the exact parent previously passed that job, and Blox passes the same infrastructure-free suite (1,450/1,450). A prior-head one-job retry and the final-head run both reproduced the hosted-runner failure. ## Verification Author Blox workstation `2020088`: - `cargo fmt --all -- --check` - `just clippy` - `just test-unit`: 1,450 passed; PostgreSQL tests remain skipped in fast jobs - PR #6660 focused tests: 4/4 passed through the final runner - Full lane: 282/282 passed in 10.087s with a non-superuser role limited to `CREATEDB`, `CREATEROLE`, and `pg_read_all_stats` - 272 desired-state tests - 10 migration-applied tests - 6 explicitly filtered external-infrastructure tests - Cleanup fault injection: a deliberately underprivileged 282-test run produced the expected 277 passes and 5 failures, and the post-run catalog audit found zero lane databases after retry cleanup. The restored successful run also left zero lane databases. GitHub exact final head `92c231e48f299ea2af23817763f5ae80ac013d68`: - [PostgreSQL Tests](https://github.com/block/buzz/actions/runs/32789030203/job/97630827823): 282/282 passed across 10 binaries in 98.886s; 1,240 skipped, including 6 via the profile filter - The shared relay/PostgreSQL archive predecessor completed successfully - [Unit Tests](https://github.com/block/buzz/actions/runs/32789030203/job/97626930420): unrelated `sherpa-onnx-c-api` native-link failure described above - Independent exact-head review on separate Blox workstation `2022762`: no substantive findings after all initial findings were addressed. The reviewer independently verified cleanup retry behavior, exit-status preservation, shell portability, syntax, and a clean exact-head worktree. ## References - Stacked on #6660 at exact head `561de54be4d9c2b622b7c2aa5b61bc3068f47e2a` - https://github.com/TheSentinel454/buzz/issues/20 - https://github.com/TheSentinel454/buzz/issues/20#issuecomment-5398526792 Generated with Codex. ## Update — August 24, 2026 review follow-up - Centralized the repeated PostgreSQL test URL resolution in crate-local, test-only helpers without introducing the broader shared utility refactor from issue #20. - Restored descriptive hybrid/Redis test function names. Structural `external_infra_*_tests` modules now own exclusion, and the nextest filter only recognizes module path segments. - Added a three-second source guard that scans every Rust file and fails CI when an ignored PostgreSQL test would be omitted or an external-infrastructure test would be included. Fixture tests cover accepted modules/binaries and both failure modes. - Removed the two implementation-plan documents. Performance profiling on Blox workstation `2027352` (same prebuilt archive and cargo-nextest 0.9.143 for every comparison): - Current per-test database model, 8 workers: 10.15–10.40s across three runs. The 283 `createdb` calls and 284 `dropdb` calls consumed 28.85–29.46 aggregate seconds, about 39–40% of aggregate test-process duration. - Reusing one database per worker without cleanup: 6.55–6.84s, about 35% faster, but all three runs failed because global matcher-queue tests inherited a quiesced community from an earlier test; the failing test varied with scheduling. - Reusing workers with `TRUNCATE … RESTART IDENTITY CASCADE`: all 282 tests passed, but total time regressed to 10.47–10.67s. The 265 truncate calls consumed 24.34–25.45 aggregate seconds, so truncation merely replaced most clone/drop cost. - Raising concurrency to 16 workers reduced one isolated-database run to 8.79s, but 24 workers exposed a cluster-global `pg_stat_activity` race. The profile remains at the proven-safe 8 workers. Decision: retain unique per-test databases. Harness cleanup uses `dropdb --if-exists --force`; it drops the database rather than truncating tables or deleting rows. Verification at local branch head `60086c1f6ee34a193c342255a5e8e6293b60e988`: - Discovery inventory: exactly 282 intended tests; all 6 hybrid/Redis tests present and structurally excluded. - PR #6660 focused persistence tests: 4/4 passed. - Full PostgreSQL lane: 282/282 passed three times; 1,240 skipped each run; wall time 9.72–9.96s without profiling shims. - Non-ignored tests with a desired-state database: 1,234/1,234 passed; one mesh-demo timeout from the first run passed immediately in isolation. - `cargo fmt --all -- --check` and all-target/all-feature clippy for `buzz-db`, `buzz-deletion`, and `buzz-relay` passed. Final independent re-review at exact head `42097c0136ab3fa8f0efe5720ae829c04575b9b6` on separate Blox workstation `2028455`: no substantive residual findings. The reviewer independently exercised ordinary strings, zero/one/three-hash raw strings, line/block comments, and string-contained lookalikes, then reran the full 353-file scan, shell syntax, Python AST parsing, and diff check. Independent review found that the source guard's initial regular expression could miss raw-string ignore reasons and treat a commented attribute as real. Final head `42097c0136ab3fa8f0efe5720ae829c04575b9b6` parses valid ordinary/raw Rust string literals only at attributes found in comment-sanitized source; regression fixtures cover both cases. The fixture suite, Python compilation, shell syntax, diff check, and full 353-file repository scan pass on Blox. ## Update — August 25, 2026 restack PR #6660 merged, so this follow-up was rebased from its former exact parent onto current `origin/main` (`8d2d0ff5ad42733e9949442c4b6358d0ba87f9a8`). The final candidate head is `05dcc2ab28948e3ab79bb44839a69f2ba44648a2`; the PR no longer carries #6660's pre-squash history. Fresh exact-head verification on Blox workstation `2028572`: - Discovery guard passed across 353 Rust files; inventory remained exactly 282 intended PostgreSQL tests. - PR #6660 focused persistence tests: 4/4 passed. - Full PostgreSQL lane: 282/282 passed three times; 1,243 skipped each run; wall time 9.70–9.87s. - `cargo fmt --all -- --check` and all-target/all-feature clippy for `buzz-db`, `buzz-deletion`, and `buzz-relay` passed. ## Update — August 25, 2026 final hosted verification - [GitHub PostgreSQL Tests](https://github.com/block/buzz/actions/runs/32801679226/job/97667835080): 282/282 passed in 53.787s; 1,243 skipped. - The final guard scanned all 353 Rust files successfully before the hosted lane ran. - The shared relay/archive prerequisite and infrastructure-free Unit Tests job both passed at exact final head `42097c0136ab3fa8f0efe5720ae829c04575b9b6`. --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Signed-off-by: tornquist <tornquist@squareup.com> |

feat(desktop): add thread-scoped ACP session experiment (#6909)
## Why Thread-scoped ACP sessions from #6732 need an opt-in desktop rollout that preserves today’s channel policy by default. ## What - Add the default-off “Thread Scoped ACP Sessions” toggle under Settings → Experiments using the existing feature-override persistence. - Map the persisted setting to `BUZZ_ACP_SESSION_POLICY=channel|thread` for every local and provider-backed managed ACP launch. Changes apply when managed agents next start; DMs remain conversation-scoped by the backend. - Keep the desktop setting authoritative over descriptor environment and cover the UI, persistence, local spawn, provider payload, and existing Projects/Workflows experiments. ## Risk Assessment Low. The experiment defaults off and explicitly preserves `channel`; changes are limited to managed-agent launch configuration. Existing running agents are unchanged until their next start. ## Testing - `. ./bin/activate-hermit && just ci` — passed on the final restacked tree, including 5,674 desktop tests, 2,796 Tauri tests, and 1,860 mobile tests. - `cd desktop && pnpm build:e2e && pnpm exec playwright test tests/e2e/experimental-features.spec.ts --project=smoke` — 1 passed. - `. ./bin/activate-hermit && cargo test --manifest-path desktop/src-tauri/Cargo.toml session_policy --lib` — 4 passed. - `. ./bin/activate-hermit && cargo test --manifest-path desktop/src-tauri/Cargo.toml commands::agents::deploy::tests --lib` — 15 passed. - `. ./bin/activate-hermit && cargo test -p buzz-backend-kubernetes --test wire_fixtures` — 4 passed. ## Stack Info Stacked on #6732.

feat(desktop): add isolated named demo builds (#6407)
🤖 I’m Larry, updating this description on Logan’s behalf. ## Summary Build named macOS demo apps without Finder automation or collisions with installed Buzz. `just desktop-demo-build "PR 6407 Demo"` produces a matching app and DMG, with a fresh build identity even when the same display name is reused. - The headless DMG packager uses `hdiutil`; optional Finder styling is bounded. The existing production release recipe is unchanged. - Each demo has independent app data, keychain, nest, CLI name, voice-model storage, repository discovery, and agent OAuth/config storage. Reset preserves production and sibling-demo state, and retains retry intent when credential removal or root resolution fails. - Native links accept only the active build’s registered scheme, then translate validated entity links into the frontend’s canonical `buzz:` format. - The recipe builds all six executable sidecars. Display names are capped at 31 ASCII characters so the generated identity fits Rust’s build-time limit. **Open delivery requirement:** downloaded demos must run without a Gatekeeper security override. The current recipe is ad-hoc signed and unnotarized; it does **not** satisfy this requirement. Trusted branch-demo signing/distribution remains blocked on establishing an approved signing path. This PR is not being presented as complete download-and-run delivery. ### Related issue N/A — reported in the Buzz DMG-packaging workstream. ### Testing At `11ce21ff97cb387ad676e7caa65b00964097d0bb`, macOS Blox passed the Tauri workspace suite and compiled-flags gate (including the full named-demo state; each library pass: 2,992 passed, 19 ignored), Tauri all-target clippy, the full `buzz-agent` package suite, and frontend lint/typecheck plus 5,733 tests. Regression coverage includes cold-start/running entity-link handling, wrong-build rejection, OAuth deletion failure and retry, unresolved credential roots, and production/sibling preservation. At the same head, an extra full named-demo/mesh-enabled run had 3,092 passing tests and one failure: a pre-existing shared-compute `auto` versus `mesh` expectation, also reproduced on the old published head `a77b25eca`. The ordinary and demo-state matrix above passes; this is not an all-features-green claim. Live macOS Launch Services delivery remains unverified. GitHub CI completed with 30 successful checks and 9 skipped. The exact-range security review has not run; its authorization notice remains open. CI success does not establish trusted signing or downloaded-app launch. Earlier demo artifacts established matching app/DMG names, side-by-side launch, and six non-empty executable arm64 sidecars. These screenshots show an earlier artifact, not a new build of the final repair commit. Signature-integrity checks are not Gatekeeper/notarization evidence. <img width="1032" height="548" alt="Buzz PR 6407 Demo disk image containing the matching app" src="https://github.com/user-attachments/assets/bca0277e-db03-4308-b280-fcad55e6d601" /> <img width="1186" height="821" alt="Buzz PR 6407 Demo running alongside other Buzz installations" src="https://github.com/user-attachments/assets/b4bf4ae5-c341-4e15-8090-9d2ea7c623b6" /> --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Signed-off-by: Larry <8cf5a83f590ec0955b11647d1c88f796a98e088c30a492c58e0e46c3026ae7a4@buzz.block.builderlab.xyz> Co-authored-by: Other Brother Darryl <cee32d92756729ee0c097c5661b879c6199931cd25315c8cf398dcbf0f155cf1@buzz.block.builderlab.xyz> Co-authored-by: Larry <loganj+sandbox-larry@squareup.com> Co-authored-by: Larry <8cf5a83f590ec0955b11647d1c88f796a98e088c30a492c58e0e46c3026ae7a4@buzz.block.builderlab.xyz> |

fix(model-capabilities): humanize databricks goose model names (#7135)
🤖 ## Summary - add curated human-readable labels for Databricks Goose models that otherwise render as fully qualified identifiers - render `data_workflow_tools.goose.goose-glm-5-3` as `GLM-5.3` - render `goose-claude-4-6-sonnet`, `goose-claude-4-7-opus`, and `goose-kimi-2-7` as `Claude Sonnet 4.6`, `Claude Opus 4.7`, and `Kimi 2.7` - make the Global Defaults closed model picker use the provider-scoped display label while preserving the raw discovered model ID as the persisted value - remove the obsolete `keepSelectedModelValueLabel` escape hatch and its raw-label override path so selected discovered models have one consistent display behavior - classify the exact discovered Goose Claude IDs with their canonical adaptive-thinking capability axes, including Sonnet 4.6's exclusion of `xhigh` - expand Rust and TypeScript alias coverage and regenerate the shared 139-vector capability corpus ## Test plan - `cargo test -p buzz-agent --lib` — 517 passed, 1 ignored - `cd desktop && pnpm test` — 5,821 passed - Desktop TypeScript typecheck — passed - Biome on the changed component — passed - `git diff --check` — passed - targeted Playwright Global Defaults regression — passed on the preceding implementation head; the subsequent commit only removes dead picker-prop plumbing Verified at `b9609d12696173aa309d2dbaf4f093a502756c36`.

feat(db): add NIP-FI identity and final-admission schema foundation (#6994)
PR 2 of the NIP-FI plan: the schema foundation. Establishes the durable server-side identity ledger and final-admission surface that the runtime phases build on. All of Phase A's migrations live here; later phases own their own deltas. Depends on nothing — PR 1 (#6776, merged) owned zero migration files. This PR's relations are shaped to store exactly what PR 1's verifier produces: issuer-qualified identity and the four denial classes. They meet in a later PR that writes a verified assertion into these tables in one transaction. ## Two internally-ordered migrations - `0041_nip_fi_identity_foundation.sql` (migration A) — core identity + base-lifecycle relations (5 tables): issuer-qualified `(iss, sub)` bindings, lifecycle history/selectors, enrollment policies, and operation receipts. Applies cleanly to current `main`. - `0042_nip_fi_authorization_foundation.sql` (migration B) — the final-admission surface (10 tables): authorization events + capacity, admission results, replay/receipt guards, audit, invalidation domains/floors, protected-object authority, authority epochs, and restore version deltas. Applies to A's resulting state. Fifteen NIP-FI relations total, zero dangling foreign keys. Identity is issuer-qualified throughout — no single-global-issuer assumption in any relation, no `Block`-hardcoding. A single deployment may run one issuer; that is config, not schema. ## Durable, immutable ledger posture All 15 relations are append-only (immutable `no_delete`/`no_truncate` triggers) and carry `community_id` as provenance, not ownership. Both migrations widen the single SQL source of truth `community_write_fence_excluded_table` so the relations are never fence-attached, never purged on community deletion, and never counted as tenant-scoped drift by the deletion control plane's exact-set catalog check — the same posture main already applies to `product_feedback` and `rate_limit_violations`. `schema/schema.sql` keeps one consolidated definition of that function whose exclusion array byte-matches `0042`, guarded by a parity assertion so a future consolidation cannot silently drop NIP-FI relations from the ledger. This makes a tenant's identity/authorization ledger survive community deletion, per the spec's `FI-INV-02` (durable binding) and `FI-INV-03` (tombstone monotonicity) and `NIP-FI.md`'s "durable server state" ruling. `communities(id)` FK never dangles: community rows become permanent tombstones, never hard-deleted. ## Authorization shape and cardinality contracts Authenticated `OperatorDenied` events (`actor_kind` 1–3, non-null `request_fingerprint`) carry a null `semantic_fingerprint` and commit without a denial-attempt row. The denial-attempt cardinality and shape guards are scoped to unresolved pre-auth kind-9 events (`actor_kind = 4`). Applied and no-op lifecycle receipts (`outcome_code IN (1, 3)`) require exactly one mapped success-transition event; denied lifecycle receipts (`outcome_code = 2`) require zero events from the complete core lifecycle success-transition class (kinds 1, 2, 3, 6: enrolled, revoked, rotated, retired) — any such event paired with a denied receipt would record a transition that never occurred. ## Mined vs. new Re-cut from Franco's #1476 (`0029`/`0030`) and Cea's #4772 committer schema, re-cut along FK topology and renumbered above the live `main` tip. The buzz-auth core of #1476 is Cea-authored; `Co-authored-by` reflects verified per-commit authorship of the mined schema. Zero Rust/`deletion.rs` edits — the migration-only exclusion widening keeps `EXPECTED_SCOPED_TABLES` untouched. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Hayt <9e1c23a3fd83f61da34420e4e88ff1b16e45cafcc0cd9019eb07d4ecfa8ca9b0@buzz.block.builderlab.xyz> Co-authored-by: Cea Stapleton Cordasco <261786559+cea@users.noreply.github.com> Co-authored-by: Hayt <9e1c23a3fd83f61da34420e4e88ff1b16e45cafcc0cd9019eb07d4ecfa8ca9b0@buzz.block.builderlab.xyz> |

feat(buzz-acp): give each channel thread its own agent session (#6732)
## What this does In a channel, people often run several unrelated conversations at once (separate threads). Today the agent treats the whole channel as one conversation, so unrelated threads share the same running session — their context bleeds together and independent tasks can step on each other. This change gives the agent a **separate session per thread** inside a channel. Direct messages stay as one conversation (unchanged). The channel is still the boundary for who is allowed in and what is visible — only the agent's working context is now split by thread. ## How it is turned on Off by default. Operators opt in with one setting: - `BUZZ_ACP_SESSION_POLICY=channel` — default, current behavior - `BUZZ_ACP_SESSION_POLICY=thread` — new per-thread behavior Being behind a flag means we can enable it for a few agents, watch how it behaves, and roll back instantly without a code change. ## Key design decisions - **Decide the thread once, up front.** When a message arrives we work out which thread it belongs to a single time and tag it. Everything after that (which line it waits in, which session runs it, what history it sees) uses that tag instead of re-guessing later, which avoids mismatches. - **Default stays identical to today.** Under the default setting a "thread" is just "the whole channel," so existing behavior and every existing test are unchanged. The new, riskier behavior is strictly opt-in. - **Give the agent only its thread's history.** On a reply the agent sees that thread's messages (including ones that did not mention it), not the whole channel transcript — less noise and smaller prompts. - **Don't let one channel use more memory than before.** More threads means more live sessions, so the existing per-channel limit now caps all of a channel's threads together — splitting into threads can't multiply how much work is held. ## Bugs found and fixed while iterating (from review) - **Same thread, two sessions.** If the worker already holding a thread's session was busy, a new message for that thread could start a *second* session on another worker and split its history. Now it waits for the right worker instead of forking. - **Interrupting the wrong thread.** A follow-up meant for thread A could interrupt thread B in the same channel. Interrupts now target the exact thread. - **Stuck thread after a crash.** If a thread's turn crashed, its slot wasn't cleared and stayed blocked for up to ~2 hours. It now clears right away and retries. - **Lost the original request.** When a thread was interrupted and then had to wait for a busy worker, only the follow-up was kept and the original request was dropped. The full request is now preserved on retry. - **Same thread seen as two.** Two spellings of the same thread id (upper/lower case) could be treated as different threads. Normalized so they count as one. ## Not in this PR - The desktop Settings toggle and rollout wiring for managed agents — https://github.com/block/buzz/pull/6909 - One pre-existing retry edge case (present today without this flag, unrelated to this change) — tracked separately so this PR stays focused. ## Testing The full `buzz-acp` test suite passes (830+ unit and integration tests), plus new focused tests for thread routing, session reuse, interrupt targeting, crash recovery, and request preservation. Behavior with the flag off is unchanged. --------- Signed-off-by: Salman Mohammed <smohammed@squareup.com> Signed-off-by: Leo <5faf251baee50ee6bcde338aef6acdd70bb3e60115664c2cd490d94a55dfc488@buzz.block.builderlab.xyz> Co-authored-by: Leo <5faf251baee50ee6bcde338aef6acdd70bb3e60115664c2cd490d94a55dfc488@buzz.block.builderlab.xyz> |

fix(relay): reject a frame on its own acknowledgement channel (#6961)
Pinky, an AI agent, updated this description on Wes's behalf after
taking over the startup investigation.
**Category:** fix
**User Impact:** An EVENT refused by WebSocket admission or handler
saturation receives a correlated `OK(event_id, false, reason)` instead
of an uncorrelated NOTICE, so the client can settle that refusal without
waiting for its publish timeout. Rate-limited refusals also arm client
backoff. This fixes a protocol failure mechanism; it does not establish
that every startup send will succeed or that the reported Desktop
startup incident is fully resolved.
**Problem:** Startup opens several live subscriptions and publishes at
once, and the relay's WebSocket admission gate is a fixed 5-second
window (`ws_admission_budget` = `human_ws_events_per_sec * 5`). If that
shared per-principal quota is exhausted, `enforce_ws_admission`
previously rejected an EVENT with a bare `["NOTICE", reason]`. Quota
pressure is a possible trigger, not proof of the original incident's
complete cause.
A NOTICE carries no event id. Both clients settle a pending publish
*only* from an `OK` keyed by event id (desktop `pendingEvents`, mobile
`_pendingEvents`), so nothing settled — and `handle_text_message`
returns early, so no `OK` ever followed either. The send **could not
fail**; it could only time out at `PUBLISH_TIMEOUT_MS` = 25s. That
explains how this rejection mechanism can produce a roughly 25-second
timeout; attributing the original report to it still requires the actual
startup/send workflow.
The handler-semaphore saturation path had the identical defect, and that
one needs no quota burst to fire.
**Solution:** NIP-01 gives each request type its own acknowledgement
channel, and a rejection is only actionable on the same one. Reject a
REQ with `CLOSED`, an EVENT with `OK(id, false, reason)`, and fall back
to `NOTICE` only where no per-request correlation exists. COUNT refusals
now also use `CLOSED(query_id, reason)` per NIP-45, covering both quota
admission and handler saturation (added in
`cd12c93804b87a24b61075dfd171dc471a0a527f`).
Reason strings are unchanged, so the `rate-limited:` prefix and `retry
in {N}s` hint that existing client gates parse keep working (desktop
`parseRateLimitHint`, mobile `RelayRateLimitGate`, buzz-acp
`set_rate_limit_gate`). Only the frame *type* changes, so
`docs/multi-tenant-relay.md` L7 stays satisfied.
Two notes on how this landed, both worth a reviewer's attention:
1. **A survived mutation became a design change.**
`send_admission_result` originally took a `RejectionTarget` parameter,
and reverting the *second* call site (the per-minute message quota)
survived the whole suite — with Redis unreachable the first quota check
short-circuits, so that line is unreachable in test. Rather than test
around it, the parameter is gone: the target is derived from the frame,
so no call site can name the wrong channel.
2. **The relay fix would have caused a client regression on its own.**
Gate arming lived only in the NOTICE branch. Once rejections arrive as
`OK:false`, `handleOk` failed the send without ever backing off — the
client would retry straight into the same quota. Desktop and Mobile now
arm on a `rate-limited:` OK rejection. ACP was subsequently fixed in
`3b06dd32493596ec650f20abf8805791c50fdc24`: it arms the gate and
re-parks only the refused observer frame, preserving other in-flight
frames. Desktop gets `activateRateLimitIfSignalled` as the single owner
of that prefix test, called from both `handleOk` and the NOTICE branch.
<details>
<summary>File changes</summary>
**crates/buzz-relay/src/rejection.rs** (new)
Owns the admission-rejection concern: `RejectionTarget`,
`rejection_target_for`, `request_rejection_message`,
`send_admission_result`, and `enforce_ws_admission`, moved out of
`connection.rs`. Six tests, two of which drive the real
`enforce_ws_admission` against a real `AppState`.
**crates/buzz-relay/src/connection.rs**
Fix the EVENT handler-semaphore rejection to correlate to the event id;
delegate admission to the new module. Add two tests that drive the real
`handle_text_message` with every handler permit held. Down from 1319 to
1116 lines.
**crates/buzz-relay/src/state.rs**
Widen the existing `test_state` helper to `pub(crate)` so the rejection
tests reuse it rather than adding a ninth copy of `AppState`
construction.
**desktop/src/shared/api/relayRateLimitGate.ts**
Add `activateRateLimitIfSignalled` — one owner for the `rate-limited:`
prefix test, since three inbound frame types now carry it.
**desktop/src/shared/api/relayClientSession.ts**
Arm the gate on a rate-limited OK rejection; route the NOTICE branch
through the same helper. Net zero lines, which keeps this
already-oversized file within the differential ratchet.
**desktop/src/shared/api/relayClientPublishRejection.test.mjs** (new)
Four tests against the real `RelayClient`: a rate-limited OK settles the
pending publish and arms the gate; an ordinary rejection does not arm
it; an accepted OK still resolves.
**mobile/lib/shared/relay/relay_session.dart**
Arm the gate in `_handleOk` for a rate-limited rejection.
**mobile/test/shared/relay/relay_session_test.dart**
Two tests driving the real `publish` + `debugHandleMessage` path.
</details>
<details>
<summary>Validation</summary>
**Mutation-tested — 5 mutations, all now killed.** Each production call
site was reverted to the defective behaviour to confirm a test fails.
This caught two false-negative tests:
| # | Mutation | Result |
|---|----------|--------|
| 1 | `rejection_target_for`: EVENT → `Connection` | 4 tests fail |
| 2 | EVENT handler-semaphore call site → bare NOTICE | **survived at
first** |
| 3 | per-minute quota call site → `Connection` | **survived**; fixed by
removing the parameter |
| 4 | desktop `handleOk` gate arming removed | 1 test fails |
| 5 | mobile `_handleOk` gate arming removed | 1 test fails |
Mutation 2 is the lesson: my first saturation test called
`request_rejection_message` directly, so reverting the real call site
inside the `match` arm left it green. It now drives
`handle_text_message` itself and dies on that mutation.
- `cargo test -p buzz-relay` — 928 passed, 1 failed:
`api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo`,
**pre-existing**, reproduced with all changes stashed at `4dd4d73de`.
- `cd desktop && npm test` — 5721 passed, 0 failed (full suite).
- `cd mobile && flutter test` — 1876 passed, 0 failed (full suite).
- `just fmt-check`, `just clippy`, `just desktop-check`, `just
mobile-check`, `just file-size-check` — clean. Desktop's 5 biome
warnings are pre-existing (reproduced with changes stashed).
- All 9 pre-push lanes green, including `rust-tests` and
`desktop-tauri-checks`.
**Not verified:** not reproduced end-to-end against a live relay under a
forced quota burst. The causal chain is source-proven and
mutation-proven at the frame level; the ~25s attribution follows from
`PUBLISH_TIMEOUT_MS` but is not directly measured. A packaged-build
click-through would close that gap.
</details>
Related work: #6957 bounds Desktop HTTP event submission, but safe
retained-operation recovery after exhausted/ambiguous outcomes remains
unfinished. #6998 is the separately reviewable Desktop
readiness/duplicate-subscription slice. Neither is claimed to complete
native before/after startup-send validation.

## Current review disposition (2026-08-28)
The [review on
`cd12c938`](https://github.com/block/buzz/pull/6961#pullrequestreview-5052902510)
identified ACP's missing rate-limited-OK handling. Commit
`3b06dd32493596ec650f20abf8805791c50fdc24` fixes gate arming, re-parking
the specifically refused observer frame, and the stale NOTICE comment.
Two regressions drive the real frame dispatcher. See [the implementation
and validation
response](https://github.com/block/buzz/pull/6961#issuecomment-5455032054).
The Mobile generation-check inline thread is resolved: its `async
publish` returns a failed Future when superseded; it does not throw
synchronously at invocation. No further production change was indicated
by that comment.
The validation counts above describe the original slice, not a new
rerun. At `3b06dd324`, the current GitHub check rollup has successful
completed test/build checks (non-applicable jobs skipped). The
security-review comment still requires review for the current base/head
range; do not read a green authorization job as a completed security
review. Approval and merge remain human decisions.

fix(acp): wake agents from workflow messages (#6953)
> Pinky, an AI agent, is opening this PR on Wes's behalf.
## Summary
Workflow-generated messages can contain a valid agent mention but still
fail the ACP inbound author gate because the relay signs the event. This
keeps the existing wake policy and gives ACP a narrowly verified
effective author:
- preserve the workflow owner's existing `p` tag and all
rendered-mention `p` tags
- add explicit `["buzz:workflow-owner", <owner hex>]` provenance to
relay-generated workflow messages
- add `["buzz:workflow-mention", <agent hex>]` authority only for
mentions resolved from the stored, unrendered workflow step template
- accept that owner only for a verified kind-9 event signed by the
relay's current NIP-11 `self` key, with unique canonical workflow
metadata and an explicit workflow mention for the receiving agent
- route the verified owner through the existing author and in-flight
mode policies in both normal and setup listeners
- refresh relay identity after reconnects, retaining the last verified
key on transient fetch errors while treating a successful response
without `self` as definitive removal
Malformed, duplicate, forged, tampered, wrong-kind, and wrong-relay
attribution all fail closed to the raw event signer. `respond-to=nobody`
remains absolute. Old/mixed-version messages without the explicit
provenance retain their current fail-closed behavior.
## Trust boundary
The workflow owner means **“scheduled by,” not “authored every rendered
word.”** Trigger-controlled substitutions may still produce ordinary `p`
mention routing for compatibility, but they cannot mint
`buzz:workflow-mention` authority. Only a target named in the durable
owner-authored step template can receive that authority.
The author gate is not bypassed: after relay signature/provenance
verification, the effective owner is evaluated under the same
`owner-only`, `allowlist`, DM, and `nobody` policies used for ordinary
messages. Owner control commands continue to use the raw event signer.
## Why this PR
This is the focused immediate fix for waking an **online** agent from a
stored workflow mention. Earlier attempts were not a finished mergeable
fix and had materially different or incomplete trust designs. Larry's
larger draft stack addresses durable delivery across restarts; that
remains valuable future work and can supersede this effective-author
path when it lands.
## Validation
At exact clean commit `fe5b55619fe44176343eefb4cb7fe180df45a7d8`:
- `buzz-relay workflow_sink`: 25/25 passed, including all four ignored
PostgreSQL cases
- `buzz-acp --lib`: 845/845 passed
- `buzz-workflow --lib`: 169/169 passed (2 unrelated PostgreSQL tests
ignored)
- warnings-denied Clippy passed for the changed Rust packages
- `cargo fmt --all -- --check` passed
- `git diff --check` passed
- repository pre-push gates passed, including branch-scoped Rust tests
- CI now selects the ACP library tests and the relay's pure + PostgreSQL
workflow-sink tests so these guards cannot silently remain unexecuted
The production event-to-author gate is shared by normal and setup
listeners and has biting regression tests for accepted explicit
attribution, legacy owner-`p` rejection, and forged-attribution
rejection.
## Exact-head local relay + ACP proof
Following the release-binary/local-relay shape in `TESTING.md`, the
exact commit above passed a fresh isolated real-process matrix using:
- a freshly recreated Postgres database with migrations
- isolated Redis
- exact-head release `buzz-relay`, `buzz`, `buzz-admin`, and `buzz-acp`
binaries
- newly provisioned owner, channel, and bot member through the CLI
- workflow creation and triggering through the running relay
- a deterministic ACP protocol subprocess capturing actual
`session/prompt` dispatches
- a NIP-11 `self` value verified against the running relay signer
Cases:
1. A stored explicit workflow mention woke an `owner-only` agent exactly
once.
2. A workflow message without an agent mention did not wake it.
3. A non-relay signer forging every workflow authority tag did not wake
it.
4. Trigger-controlled `{{trigger.text}}` containing `@Wake Agent`
retained ordinary `p` routing but received no authority-bearing
workflow-mention tag and did not wake the agent.
5. `respond-to=nobody` remained absolute for a valid relay-authenticated
workflow mention.
The deterministic ACP subprocess isolates and directly proves relay →
ACP authorization and prompt dispatch without depending on external
model behavior.
## Deployment and residual risk
Relay and ACP changes must be deployed together for the new wake
behavior; mixed versions fail closed. Production paired-deployment proof
remains distinct from the successful local integration run. Setup-mode
behavior has automated coverage but was not a separate case in the
five-case local matrix. Relay-key rotation is observed at ACP
startup/reconnect; transient NIP-11 errors retain the last verified key,
an intentional availability tradeoff documented in code.
