+-- Chat messages, owned by the `chat` worker. One row per message posted to a thread;
+-- columns rather than a JSON blob (mirroring the reference model), since every field is a
+-- scalar the server reads: threads are listed newest-first by (chat_thread_id,
+-- chat_message_id), and `time_sent` is carried for display only.
+--
+-- `chat_message_id` is server-assigned (AUTOINCREMENT) so ids are unique across every
+-- thread, matching the client's expectation of a global message id. `contents` is the
+-- client's envelope — `{"Type":0,"Version":1,"Data":"..."}` — stored verbatim as an
+-- opaque string and served back untouched, so new message types need no schema change.
+-- `moderation_state` is the ChatModerationState enum (0 = none). Kept in sync with
+-- SCHEMA_DDL in src/message-db.ts.
