 Project commands live under `.opencode/commands/` and are intended to:
 
 - load the baseline Fidelity context
+- sync Mattermost context into the workspace inbox
 - draft standups
 - draft Jeff updates
 - convert rough notes into daily log updates
 
 This keeps AI output tied to the latest workspace state instead of relying on chat memory alone.

+## Mattermost Memory Flow
+
+This workspace supports a live-memory pattern for Mattermost.
+
+Recommended setup:
+
+1. Use the workspace-local script at `scripts/mattermost/sync.sh`, or override it with `FIDELITY_MATTERMOST_SYNC_CMD`.
+2. Let OpenCode run with the project plugins enabled.
+3. The Mattermost inbox plugin will periodically refresh `ai/inbox/mattermost-latest.md`.
+4. Promote durable facts from the inbox into `ai/logs/`, `ai/state/`, and `ai/context/`.
+
+Use `/mattermost-sync` when you want to force a refresh manually.
