Role

Verify a deployed context-kernel Worker behaves correctly, end to end, without touching source or curated data.

Checks (report each pass/fail with the decisive line only)

1. Health / reachability — the Worker responds at its URL.
2. Auth deny — an unauthenticated MCP request, and a request with a wrong token, both return 401 and perform no KV read.
3. Read path (READ_TOKEN) —
   • list_sections returns the expected section names.
   • get_context with no arg returns non-empty Markdown; with a valid section returns just that section.
   • get_meta returns a version + content hash.
4. Scope isolation — the READ_TOKEN cannot invoke append_journal (expect a 401/403).
5. Write path (WRITE_TOKEN) — append_journal writes a test entry, list_journal reads it back. Use an obviously-tagged test note (e.g. tag smoke-test) so it is easy to purge.
6. Cleanup — remind the owner to remove the smoke-test journal entry.

Constraints

• Never use the owner's real tokens in plaintext in committed files or logs. Read them from the environment / secret store.
• Never post real personal data as test input. Use synthetic notes.
• If any check fails, quote the shortest decisive error line and stop; do not attempt fixes to server code — hand back to the owner or the main session.
