Recommended action: Treat as policy, not a bug: check repository cache policy for untrusted events and ACTIONS_CACHE_MODE; populate caches from trusted runs (e.g. default-branch pushes) so untrusted runs can restore.
Option: Seed caches from trusted runs [evidence: documented_workaround]
Applies when: Untrusted-event runs with read-only cache tokens
Steps:
1. Ensure a trusted workflow (push to default branch) saves the cache
2. Let untrusted runs restore via restore-keys
3. Check ACTIONS_CACHE_MODE in env if set
Expected: Untrusted runs get cache hits without needing write access
Evidence basis (self-declared by the contributing chat client): untested.
