## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Managed workspaces run local web services and embedded PostgreSQL
databases
> - A listening process could return an unhealthy response and still be
reused
> - Embedded PostgreSQL failures had no bounded restart owner
> - Cleanup inferred ownership from a branch slug instead of exact
persisted instance data
> - This pull request validates runtime health, supervises database
recovery, and uses exact cleanup ownership
> - The benefit is reliable replacement of degraded services without
deleting active instances
## Linked Issues or Issue Description
**What happened?**
Workspace reconciliation could reuse a degraded Paperclip process after
any successful HTTP response. Embedded PostgreSQL could stop without
bounded recovery. Cleanup could infer database ownership from a branch
slug and select the wrong instance.
**Expected behavior**
Paperclip must require a semantic healthy response from the assigned
loopback listener. It must replace degraded processes. It must supervise
embedded PostgreSQL with bounded restarts. Cleanup must use exact
persisted worktree and instance-root ownership.
**Steps to reproduce**
1. Start a managed workspace runtime.
2. Make its health endpoint return HTTP 200 with an unhealthy status, or
stop its embedded PostgreSQL process.
3. Reconcile the workspace or run instance cleanup.
4. Observe that the old implementation can reuse the degraded runtime or
infer ownership from its branch slug.
**Paperclip version or commit**
Current `master` before this pull request.
**Deployment mode**
Local dev with managed workspace services.
## What Changed
- Require `{ "status": "ok" }` from the assigned loopback health
endpoint before runtime reuse or adoption.
- Refresh persisted runtime health and replace degraded managed
processes.
- Add bounded embedded PostgreSQL restart supervision with coordinated
shutdown and hot-restart support.
- Stop the unhealthy web process when PostgreSQL recovery is exhausted
so reconciliation can replace it.
- Require exact persisted instance-root ownership before cleanup can
reclaim an embedded database.
- Add focused regression tests for degraded HTTP responses, ownership
mismatches, bounded recovery, active instance preservation, and
confirmed orphan reclamation.
## Verification
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm --filter @paperclipai/server test --
src/embedded-postgres-supervisor.test.ts
src/services/workspace-instance-cleanup.test.ts
src/services/workspace-runtime.test.ts
src/services/execution-workspaces-service.test.ts`
- `pnpm -r typecheck`
- `pnpm build`
- `git diff --check`
- The full local stable test runner also found host-owned listeners on
ports 42000 and 52000. Those listeners conflict with the exposure test
fixture. The focused changed suites pass, and CI runs on a clean host.
## Risks
- A custom process that returns HTTP 2xx without the Paperclip health
contract is now degraded by design.
- Restart exhaustion terminates the managed web process. The runtime
reconciler then starts a clean process.
- Cleanup now fails closed when persisted ownership is missing. This can
retain an ambiguous orphan for manual review.

## Model Used
- OpenAI GPT-5 Codex. The exact serving revision and context-window size
are not exposed. The model used agentic reasoning, repository tools,
code execution, and test execution.
