Registry/feed protocol
GitHub Actions cache old versions retired cache service backend brownouts shutdown actions/cache v1 v2 February 2025
Restore/save begins failing during brownouts or after shutdown while other steps pass.
Agent Quick Fix
Repair against the current GitHub Actions cache contract, then keep the change narrow and source-backed.
Product: GitHub Actions cache
Current-contract area: Old actions/cache release targets retired cache backend
Likely root cause: Restore/save begins failing during brownouts or after shutdown while other steps pass.
Repair direction: Verifier checks continuity, cursor advancement, de-duplication, and compatibility with the current feed. Verify an updated action/runner protocol and correct restore/save behavior.
Symptom
Restore/save begins failing during brownouts or after shutdown while other steps pass.
Why This Happens
The consumer code is locally valid under the old feed contract; only the live registry's current routing, cursor, or response semantics disambiguate the fix.
Common Wrong Fixes
- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
