+- **Docker: reasoning mining found zero traces.** `docker-compose.surrealdb.yml`
+  now mounts the host's `~/.claude/projects` read-only into the dashboard
+  container at `/home/appuser/.claude/projects`. Without it the in-container miner
+  scanned an empty `~/.claude` and every dashboard "Mine" finished instantly with
+  0 traces (no error) — looking like nothing happened. Projects-only, read-only
+  mount (not the whole `~/.claude`); override via `HOST_CLAUDE_PROJECTS` in `.env`.
