201 relay cell process exits over 48h on 2026-09-04 paged nobody. Adds a log metric on the Docker `container die` event for the orca-relay container, an alert at >3 exits per instance per 15 min, and a four-chart incident dashboard covering the signals that had to be assembled by hand during the outage.
* feat(relay-infra): dynamic NAT ports and alerts for the 2026-09-04 stall signals
Relay cells reach Cloud SQL's public IP through Cloud NAT. The static default
of 64 ports per VM filled on 2026-09-04 and every cell's proxy dial timed out
at once, which read as a fleet-wide SQL stall against a healthy database.
Switch both regional NATs to dynamic port allocation (64..4096 per VM).
Add the three alerts that would have paged inside the first ten minutes:
- Cloud SQL WAL-triggered checkpoint loop (log metric on
"checkpoint starting: wal", > 3 in 5 min)
- Cloud SQL disk utilization > 70%
- Cloud NAT OUT_OF_RESOURCES packet drops on the relay gateways
No workflow applies google_monitoring_* or the NAT resources today; every
relay workflow is target-scoped to cells. Apply is a reviewed targeted plan
(see PR body).
* test(cloud): register the three new relay alert policies in the root partition fixture
The five `node ... | tee` steps in cloud-operate-relay-production-rehome-job.yml
reported tee's exit code, so a thrown inspect or apply passed green. The Aug 28
21:25Z and Aug 29 inspects and today's first inspect all printed
"director returned an invalid regional rehome control" (the durable control had
moved to generation 12 when the Aug 28 rehome aborted) and still succeeded.
`shell: bash` adds `-o pipefail`. A test pins the default and the tee count.
Mirrors stablyai/orca-cloud#470. The private relay workflows are retired, so
the dual accept has one live arm left. Add `github_workflow_file_prefix` for
the primary repository's workflow filenames, point `github_repo`/
`github_repo_id` at `stablyai/orca` (`1183888342`), and empty
`github_accepted_repositories` in both environments. Every relay provider goes
back to a single arm naming `cloud-` prefixed workflow refs.
`cloud/infra/terraform` stays byte-identical to the private branch. The two
identity tests diverge here as they already did, so they take the same change
rather than the same bytes: both now render the trusted ref head from the
Terraform variable instead of this checkout's own workflow filenames, which is
what lets the length pin be the same 791 characters in either repository.
* chore(cloud): pin staging relay c3 to the director's image
Mirrors stablyai/orca-cloud#468. c3 stayed on sha-c91439af after the
director and c4 moved to sha-e3e92d95, so the staging capacity proof's
compatible-director-image check has failed since 2026-08-14.
* test(cloud): scope the launch-image pin to staging C4 now that C3 shares the digest
* test(cloud): keep the public workflow assertions; scope only the launch-image pin to C4
The relay root does not declare it (it belongs to the private apps root), and
Terraform rejects an undeclared -var, so the first public Deploy Relay Staging
run failed at the C4 image bind.
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.
