Ports the relay's #18722 pattern to the gateway: DDL runs on a one-connection
pool with statement_timeout 0 that is closed before the serving pool opens, and
SQLSTATE 57014 joins the bounded transaction retry path.
- app.onError logs only the error name and answers a bare 500; hono's default
handler printed the whole error, and a pg error carries the row in detail
- a second per-IP bucket (240/min) runs ahead of the bearer lookup on every
authenticated route, so forged bearers cannot spend the two-connection pool
- one live session per host: minting deletes the host's earlier row
- device-less hosts are pruned after 1 h, not 30 d; any keypair mints one free
- notificationId is printable ASCII, since it becomes the APNs collapse header
- the impersonated FCM probe token is masked in the workflow log
- prevent_destroy on the Apple secrets and the orca_push database
- Roll traffic back on a failed post-shift check; delete a candidate that
never took traffic; retry the origin probe and the FCM probe.
- Assert Terraform-owned scaling instead of mutating it from the workflow.
- Build before taking the Cloud SQL rollout lease.
- Declare the database pool in Terraform (2 per instance, max 2 instances)
and add the gateway to the connection budget; the previous default put the
shared instance 65 connections over its ceiling.
- State plainly that the shared deploy identity's relay authority is inherited.
The production domain-restricted-sharing policy rejects an allUsers
run.invoker member, which the runbook anticipated. Opt the service out of
invoker IAM the way the relay director already does; the host proof is the
authentication either way.
Declares the Cloud Run service, runtime account, secrets, and orca_push
database behind push_gateway_enabled, true only in production. The deploy
workflow is gated like the relay's, deploys with no traffic, probes /ready
and a validate-only FCM send, then shifts traffic. It runs as the shared
production deploy account because the Cloud SQL rollout lease grant is
foundation-owned; its extra authority is three bindings on the push service.
docs/push-gateway.md carries the import commands for the resources created
by hand and the APNs key rotation procedure.
All 19 general cells on 4916ed67, selector gen 148 -> 186, 0 serving-process
exits across the roll. Three waves used the no-restart mode=rollback resume
(c13 transient trust-probe 409; c26/c21 post-apply runtime-status 503 shed).
Checklist: 2.3, 4.1, 4.3 relay side deployed; status header 2026-09-06.
Operator record for the 2026-09-04 relay reconnect incident and the Roll 1
same-cap cell image roll (complete 2026-09-05, selector gen 148), plus the
follow-up checklist, roadmap, and the Roll 2 implementation plan.
Docs only; split out of #18565 so the record merges independently of the code.
The global relay_cells FOR UPDATE lock made successful retries a
steady-state rate: fleet-wide p50 430 / p90 924 / p99 1320 / max 1504
per five minutes over the last 24 h, 55% of windows over the 300 bar,
only 22% of 15-minute gates clean. Three read-only dry-runs on
2026-09-04 froze on it, blocking the same-cap roll that carries #18521
and the beginProof crash guard to the 23 cells. 2000 clears every
measured healthy gate; the exhausted-retry, director concurrency, and
pool bars keep the incident discriminator role.
* fix(cloud): recalibrate the relay monitor's exhausted-retry freeze to a measured bar
The pre-drain dry-run froze at minute one on relayPostgresRetryExhausted: 0
in every run since #18521 reached the director, blocking the cell roll that
carries the same fix. #18521 made contended request-path waiters fail fast
(500 ms) instead of succeeding slowly, so exhaustion is now a steady
contention rate: 236/236 five-minute windows non-zero over 23 h; post-#18521
p50 42 / p90 147 / max 220 fleet-wide; the 2026-08-23 incident peaked at 467.
300 clears every measured healthy window and stays under the incident shape.
/v1/assign 503 share was unchanged by #18521 (13.9% vs 12.3%).
* test(cloud): pin the exhausted-retry freeze boundary at exactly 300
* docs(cloud): reword relay comments that still described the zero exhausted-retry bar
Phase 6 of the relay split: the relay's deploy/operate surface moves under cloud/ with 24 cloud-* workflows gated on ORCA_CLOUD_OPERATIONS_ENABLED, the Cloud SQL rollout lease action, the relay Terraform root (dual-accept identities for both repositories), scripts, docs, CODEOWNERS, and a terraform validate job in Cloud Verify.
