- SessionManager: add flushed flag, _persist() flushes all entries when first assistant seen
- SessionManager: reset() now creates session header
- MomSessionManager: same pattern, remove pendingEntries/sessionInitialized/startSession/shouldInitializeSession
- log.jsonl is source of truth, context.jsonl syncs from it at run start
- Backfill fetches missing messages from Slack API on startup
- Messages sent while mom is busy are logged and synced on next run
- Channel chatter (no @mention) logged but doesn't trigger processing
- Pre-startup messages (replayed by Slack) logged but not processed
- Stop command executes immediately, not queued
- Session header written immediately on new session creation
- Deduplicate messages by timestamp
- Strip @mentions from backfilled messages
- Remove old slack.ts and main.ts, rename *-new.ts versions
- Remove user message logging from agent.ts (Slack handler already logs it)
- Add excludeTimestamp param to syncFromLog to skip current @mention
- Sync happens once before each prompt with current message excluded
- Ensures channel chatter and backfilled messages are in context
- Syncs on session creation and before each subsequent run
- User messages formatted as '[username]: text' in context
- Export AgentSession, SessionManager, SettingsManager, compaction from coding-agent
- Create MomSessionManager for channel-based context.jsonl storage
- Create MomSettingsManager for mom-specific settings
- Refactor agent.ts to use AgentSession instead of ephemeral Agent
- Split logging: tool results go to context.jsonl, human messages to log.jsonl
- Enable auto-compaction and overflow detection from coding-agent
