fix(ci): wait for Go release checksum readiness

[sunib]

Release 0.7.0 initially failed because Go's checksum service returned unknown revision gateway/v0.7.0 immediately after Release Please created the tag. This blocked the consumer check and npm publication; the same release passed on rerun.

After validating the release tags, preparation now waits for checksum records for both Go modules before starting CI. It checks the lookup responses once a minute within a 30-minute deadline, covering the Go module services' cache window. Only an exact missing-tag response for that module and version permits waiting. Unexpected responses and network failures stop preparation immediately, including when the other module is still propagating.

The readiness command requires the version explicitly supplied by release preparation, so it never reads the local manifest into an outbound lookup URL. The consumer check runs once with normal Go checksum verification. Release Please continues to own versions, changelogs, and tags. The preparation job has a 40-minute timeout, and the release guide describes the readiness step and recovery.

Validation:

• task fixtures-check, task test, task lint, actionlint, and all 20 release regression tests passed.
• Regression coverage includes a missing tag alongside an unrelated error, wrong module/version responses, combined error text, immediate readiness, eventual readiness, and a deadline that includes request time.
• A CLI regression test confirms readiness rejects a missing version before reading a local manifest.
• The readiness command succeeded against the published 0.7.0 checksum records.

📝 Walkthrough

Walkthrough

The consumable CI job now retries specific Go module revision errors during release runs and has a 40-minute timeout. The release guide documents the retry limit, checksum verification, and recovery steps.

Changes

Release CI module-fetch retries

Layer / File(s)	Summary
Module-fetch retry behavior .github/workflows/ci.yml, docs/releasing.md	The consumable job retries matching checksum lookup errors during release runs, up to 30 attempts with 60-second waits. Other errors fail immediately, and successful output is printed. The job has a 40-minute timeout. The release guide documents the retry behavior and recovery steps.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 43042

A mixed-error release fetch can be retried instead of failing immediately, delaying the consumer check by up to the bounded retry window. The impact is limited to release-CI time, so the merge risk is low.

Security Architecture Review

Security architecture risk: ⚪ Minimal · up to 43042

The retry extends recovery time without granting additional privileges, disabling checksum verification, or allowing publication after failed validation. No material security risk was found in the changed release behavior.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The changed behavior affects validation duration and publication availability for this repository's selected release. It does not expand the validation job's authority to publish packages or modify release state.

Trust Boundaries and Controls

• inferred — External fetch diagnostics influence whether validation waits, not whether it passes. Even misleading matching text cannot directly cross the publication boundary: successful module retrieval, consumer checks, and the downstream CI dependency remain required.

Resilience and Maintainability Implications

• inferred — Partial fetch attempts occur in a temporary consumer module workspace rather than modifying tags or publication state. Persistent failures remain fail-closed, with the job timeout limiting interruption and recovery duration.

go-get.log so it retries only when the checksum lookup and this release’s
unknown revision form the expected error, and immediately fails when the log
also contains any unrelated failure. Do not treat separate substring matches
anywhere in the log as sufficient to retry.
