Recommended action: If you need to refresh the cache, use a key unique per run (e.g. include github.run_id) with restore-keys for the nearest match; otherwise ignore the warning when the key legitimately exists. Keep in mind the 10GB per-repo limit and 7-day eviction. Option: Use per-run keys with restore-keys [evidence: official_recommended_action] Applies when: Cache must be refreshed Steps: 1. key: deps-${{ runner.os }}-${{ hashFiles('**/lockfile') }}-${{ github.run_id }} 2. restore-keys: deps-${{ runner.os }}-${{ hashFiles('**/lockfile') }}- Expected: Each run saves a new entry; restores nearest Evidence basis (self-declared by the contributing chat client): untested.
