 - If you create ephemeral files, you MUST delete them when you're done with them.
 - Use Docker to build and run the Slack bot in development mode, K8S for production.
-- NEVER create files unless they're absolutely necessary for achieving your goal. Instead try to run the code on the fly for testing reasons.
 - NEVER proactively create documentation files (\*.md) or README files. Only create documentation files if explicitly requested by the User. If you need to remember something, add it to CLAUDE.md as a a single sentence.
 - ALWAYS ignore `/dist/` directories when analyzing code - these contain compiled artifacts, not source
 - If you're referencing Slack threads or users in your response, add their direct links as well.

 ## Persistent Storage
 
-Worker pods now use persistent volumes for data storage:
+Worker deployments use persistent volumes for session continuity across scale-to-zero:
 
-1. **Persistent Volumes**: Each worker pod mounts a persistent volume at `/workspace` to preserve data across pod restarts
-2. **Auto-Resume**: The worker automatically resumes conversations using Claude CLI's built-in `--resume` functionality when continuing a thread in the same persistent volume
-3. **Data Persistence**: All workspace data is preserved in the persistent volume, eliminating the need for conversation file syncing
+1. **Per-Deployment PVC**: Each worker deployment gets its own PersistentVolumeClaim (1 thread = 1 PVC) mounted at `/workspace`
+2. **Session Storage**: Claude SDK sessions are stored in `/workspace/.claude/` (via `HOME=/workspace` environment variable)
+3. **Auto-Resume**: When a worker scales back up, it automatically detects existing sessions in `/workspace/.claude/` and uses Claude CLI's `--continue` flag to resume
+4. **Cleanup**: PVCs are automatically deleted when deployments are cleaned up after thread inactivity
+5. **Docker Mode**: Uses host directory mounts at `./workspaces/{threadId}/` for equivalent persistence
