 ### Assistant outcome
 Updated the Mastodon post formatter to emit `Logged on 2026 August 29 - 21:10 from: <url>` using the saved link timestamp in UTC, preserving the surrounding title/comment/tag layout and leaving the existing Mastodon posting path unchanged. Verified the targeted Mastodon regression tests pass with `PYTHONPATH=. pytest backend/tests/test_api.py -k mastodon -q`.
+
+### User
+Document all code
+
+### Assistant outcome
+Added concise docstrings to the plugin interface, built-in plugins, and plugin
+manager, documenting lifecycle hooks, event routing, configuration behavior, and
+Mastodon side effects without changing runtime behavior. Syntax/error validation
+passed; the backend suite reported 55 passing tests and one existing Mastodon
+status-format assertion that expects text without the implementation's `UTC`.
