+# reviewable-cache-rfc
+
+A proposal for adding an offline cache to the Acme command line tool.
+
+The cache should let users repeat read-only commands while disconnected. Writes
+must continue to fail offline. Reviewers need to decide cache invalidation,
+maximum age, storage location, and the security treatment of cached responses.

+# Offline cache proposal notes
+
+Current behavior requires network access for every command.
+
+Proposed behavior:
+
+- Cache successful read-only responses for up to 24 hours.
+- Never cache credentials or write responses.
+- Add `--offline` to require cache-only reads.
+- Return a clear error when no eligible entry exists.
+
+Open decision: whether the default storage location should be user-wide or
+repository-local.
