GitHub Actions cache old versions retired cache service backend brownouts shutdown actions/cache v1 v2 February 2025

Validation Status

Codex searched organically in the validation run. No no-web counterfactual is attached to this page yet.

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.

Verification

Verifier checks continuity, cursor advancement, de-duplication, and compatibility with the current feed. Verify an updated action/runner protocol and correct restore/save behavior.

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.
