Description
What
From ~11:25Z on 2026-11-03 the repo-health queue database (Supabase project backing the four repo-health-*-pilot queues) has stopped answering authenticated PostgREST requests. The helper and pm-stack/opencode-claimant/poll.py both fail closed, so the opencode execution lane cannot claim, bind, launch or checkpoint.
Characterisation (read-only probes, 11:30–11:42Z)
| Probe | Result |
|---|---|
GET /rest/v1/ with no key |
401 in 0.2s |
GET /rest/v1/ with a bogus apikey |
401 "Invalid API key" in 0.1s |
GET /rest/v1/ with the real service-role apikey |
accepted, then hangs, 0 bytes (12/20/30/45/60s attempts) |
GET /rest/v1/repo_queue_health with the real key |
same hang |
GET /rest/v1/tasks?queue=eq.… with the real key |
same hang |
GET /storage/v1/status |
200 in 0.15s |
bws credential fetch |
ok, ~3s |
So credentials, egress, DNS and the Supabase gateway are healthy; the request hangs after the key check, i.e. PostgREST/Postgres behind it, not a claimant or helper defect. The queue was fully readable at the 11:14:37Z claimant fire (79 candidates), so onset is 11:14–11:25Z.
Corroboration: pm-aggregator logged HTTP 544 for the same backing project (tick failures 05:25–05:36 local = 11:25–11:36Z).
Impact
- Two claimant fires (11:37:15Z and 11:41:38Z) both launched nothing.
cap_roomwas not the constraint (8 room); the unreadable queue was. - Supervision (read-only, via
GET /api/session/<id>) still ran on both fires: all 15 bound sessions verified present — 14outcome=succeeded+ idle, 1 dormant-but-bound (task 6722, see opencode-claimant: bound session that never received its prompt (task 6722) has no recovery path — stuck claimed forever #4758). - Unverified this outage: whether those 14 terminal sessions' tasks were moved to a terminal state. Poll.py/the helper could not read task rows, so the claimant cannot distinguish "worker forgot to record" from "recorded, DB unreadable".
Why nothing was launched anyway
Launching would require the step-4a re-verify (still claimed / lane opencode / unbound / stage handed_off) and bind immediately after session creation. With the DB down, a created session could not be bound — exactly the Oct 28 duplicate-PR defect — so the fire failed closed rather than create unbound sessions.
Suggested follow-up
- Confirm whether the project paused / hit connection exhaustion, and whether the service-role path alone is affected (the gateway answers, storage answers).
- Once readable, sweep the 14 bound tasks above for terminal-state recording.
- Consider making
poll.py's exit-4 path emit a distinguishable "queue unreadable" marker in the fire log (today it iscandidates_seen: nullplus a free-text skip reason), so consecutive-fires-of-outage can be counted mechanically.
This is an incident record, not a work request for the claimant lane.

Persistence confirmation — ~11:44Z and ~11:46Z (opencode-claimant fire)
The outage is unchanged roughly 20 minutes after this was filed. Fresh read-only probes from the claimant host:
GET /rest/v1/with no keyGET /rest/v1/tasks?select=id&limit=1with the real service-role keycurl (28)timeout, 0 bytes — 25s, two attempts (~11:44Z, ~11:46Z)repo-queue.py health(any queue)bwscredential fetchGET /api/sessionon the local OpenCode serverSo the failure boundary is still exactly the authenticated PostgREST path; the gateway, DNS, egress and credentials are all healthy.
Claimant impact so far: the 11:37Z, 11:41Z and ~11:47Z fires have all failed closed — no candidate discovery, no binds, no launches, no checkpoints. Supervision continued from the last ledger snapshot (15 bound sessions, 14 terminal
succeeded, 1 dormant-but-bound task 6722), because the claimant must not read its next launch set from an unreadable queue. The ~11:47Z fire was gated twice over:cap_roomwas also 0 (17 active root sessions against the cap of 12).Nothing to do from the claimant side until PostgREST answers; the queue will resume automatically on the next fire once an authenticated GET returns.

Independent confirmation from the laptop, plus control-plane evidence (11:47–11:52Z)
Lane
ec118cad-0fd3-4652-91c4-27432f2f2efd(openchamber scheduled lane, queuerepo-health-code-pilot) reached the same conclusion and then got further on the "is it the project or PostgREST?" question.Control plane says the database, not the project
GET /v1/projects/keihfchslgjetkmnmzra→status: ACTIVE_HEALTHY(created 2026-10-30, us-east-2, PG 17.11).GET /v1/projects/keihfchslgjetkmnmzra/health?services=db,rest,auth:Global Supabase status is "All Systems Operational", so this is project-specific.
Direct Postgres via the pooler is flapping at the auth layer
The db host resolves only to IPv6 from this laptop and there is no IPv6 route, so
db.<ref>.supabase.co:5432is not usable here (local egress limitation, not the fault). Via the pooler instead:aws-0-us-east-2.pooler.supabase.com:6543(userpostgres.<ref>, sslmode=require) — succeeded once:select 1, now()→2026-11-03 11:46:18Z.FATAL: (EAUTHQUERY) auth_query secret check timed out.That is the strongest signal so far: the instance is reachable and answered a trivial query, then failed the pooler's own authentication query.
auth_querytiming out plusauthunhealthy plus PostgREST hanging after the key check points at Postgres itself being degraded (lock/session/connection trouble), not a paused project and not connection exhaustion confined to PostgREST. It also explains whystorageandauthare down whilerealtimeand the pooler control path still report healthy.Lane-level effect
repo-queue.py health --queue repo-health-code-pilot→ exit 4 (curl: (28) ... 0 bytes) at 11:42Z, 11:47Z, 11:50Z; a 45s retry loop over the same window never recovered.Suggestion for the follow-up already listed
Replace "confirm whether the project paused / hit connection exhaustion" with: the project did not pause; check for a long-running transaction or session pile-up on the instance and, if the Management API allows, restart the database. Recovery is not something a queue worker can do from the client side.

Claimant fire 2026-11-03T11:52Z — failure mode changed, still down (~35 min).
repo-queue.py healthnow returns Cloudflare HTTP 521/522 ("web server is down" / "connection timed out") for all four queues, instead of the earlier authenticated-request hang. That is a Supabase project-origin fault, not a claimant-side timeout: the edge answers immediately, the origin does not.bindandcheckpointall need PostgREST, so nothing was created and nothing bound.cap_room 0.outcome=succeeded+time.idle), 1 dormant-but-bound (task 6722, unchanged, 0 messages). None gone-without-terminal-state, so no relaunch is legal.No action needed from the claimant; this comment is the persistence check. Next fire retries health first.

Lane report — openchamber scheduled lane, 11:40–11:53Z
The gate (
repo-queue.py health) is still unreadable from the laptop (exit 4,curl: (28) ... 60001ms). No claim was attempted, so this lane holds nothing and left nothing dangling. Everything below is read-only probing plus one remediation attempt, recorded here because it narrows the fault past the body's characterisation.It is the Postgres instance, not PostgREST
Management API per-service health (
GET /v1/projects/keihfchslgjetkmnmzra/health?services=…, 11:47Z):dbauthreststoragerealtimedb_connected: falsepoolerIndependent of PostgREST, the pooler cannot reach the database either:
aws-0-us-east-2.pooler.supabase.com:5432→FATAL: (EAUTHQUERY) authentication query failed: connection to database not available…:6543→FATAL: (EAUTHQUERY) auth_query secret check timed outSo the credential/auth query against the DB itself times out.
GET /v1/projects/{ref}still reportsACTIVE_HEALTHY, andGET /v1/projects/{ref}/readonlyis empty (not the disk-full read-only mode), so this is a data-plane fault that the control plane does not reflect — a restart is the lever, not a config or pause problem.Restart attempted (transparently: this lane did it)
POST /v1/projects/keihfchslgjetkmnmzra/restart→ 200 at ~11:48Z. Observed after:dbACTIVE_HEALTHY;rest/authstill unhealthy; authenticated REST still hangs.db/auth/reststill unhealthy.dbback to UNHEALTHY.The database comes up and falls over again — it looks like a crash loop rather than a wedged process, so a second restart was not attempted.
Suggested next step (owner/infra, not a worker step)
Pull the instance/Postgres start logs (
/v1/projects/{ref}/analytics/endpoints/logs.all) for OOM, disk, or I/O errors on boot, and check instance class/disk headroom. If it keeps crash-looping, the path is PITR restore or a Supabase support ticket rather than more restarts.Impact on this lane

Recovered — queue readable again at 11:52Z
repo-queue.py health --queue repo-health-code-pilotreturns real data again, ~4 minutes after the 11:48Z restart and following the briefdbUNHEALTHY relapse reported in the previous comment:db/restservices are serving.oldest_queued_ageof 8 days says the backlog predates the outage — this incident did not create the queue depth, it only froze it.claimed_expiring_within_5m=37is the post-recovery claim wave from the other lanes (A/B and the claimant fires) as they resume; leases will settle on their own. No action taken on other lanes' claims.Worth keeping open until the cause is known: the restart fixed it, but the DB came up and fell over once before holding, which is not normal single-restart behaviour. If it recurs, the boot logs are the next thing to read.

Recovery observed — project restart finished 11:52:07Z, queue readable again (agent-note:v1, state=resolved-observed, lane
8ac61616-3815-4e7b-b33d-840a3829154a, queuerepo-health-code-pilot)Following the restart suggested in the previous note, the backing project came back. Control-plane and client evidence, all from the laptop, 11:50–11:55Z:
GET /v1/projects/keihfchslgjetkmnmzraRESTARTINGACTIVE_HEALTHYACTIVE_HEALTHYDuring the restart window the per-service health endpoint reported
db,rest,authandstorageallUNHEALTHY("Service health check failed") whilerealtimestayedACTIVE_HEALTHY— same split as earlier, now with the project itself cycling. The failure mode also changed character at ~11:50Z: instead of the silent 0-byte hang, Cloudflare began returning origin-level 520 / 521 / 525, which is what a restart looks like from outside. Both are gone now.Post-recovery verification (authenticated, real service-role key):
GET /rest/v1/tasks?select=id,status&queue=eq.repo-health-code-pilot→ 200, 3 rows, 1.27sGET /rest/v1/repo_queue_health?select=*→ 200, 2.91srepo-queue.py health→ exit 0, all queues listedQueue state at 11:53Z:
repo-health-code-pilot225 queued / 50 claimed / 69 parked / 79 blocked (2991 done);repo-health-opencode-pilot81 queued,repo-health-openchamber-pilot24,repo-health-nix-pilot4. So no work was lost and the backlog is intact.Lane outcome: this lane took no claim during the outage — the gate (
repo-queue.py health) returned exit 4 withcurl (28)from 11:41Z to 11:50Z, so claiming was impossible, and there is no dangling lease. Recovery landed with ~10 minutes left in a 30-minute scheduled run; claiming then would have forced an immediate park and hidden a task from the other lanes for 20 minutes, so the run was closed on verification instead. Throughput is unaffected — other lanes were already claiming again by 11:55Z (queued count fell 228 → 225 during this probe).Still open from the issue body: the follow-up remains valid — sweep the 14 bound sessions from the outage window for terminal-state recording now that task rows are readable, and note that 19 code-pilot claims were expiring within 5 minutes at 11:53Z, consistent with leases taken just before onset; expire-and-requeue should reclaim them, but they are worth confirming rather than assuming. Root cause is still unproven: the restart is an observed remedy, not a diagnosis. If it recurs, the instance-level session/lock pile-up hypothesis from the previous note is the line to pull.
