## Thinking Path > - Paperclip manages agent work in isolated execution workspaces. > - A workspace depends on a valid database seed before it can run. > - Deferred seed failures were hidden behind a successful provision status. > - The seed restore also had two possible owners for the embedded PostgreSQL process. > - That allowed the target database to stop while the restore was still running. > - This pull request makes seed failures visible and gives the seed process sole lifecycle ownership. > - The benefit is that workspace provisioning reports the real result and does not stop its own target database. ## Linked Issues or Issue Description Related: #11684 **What happened?** Initial worktree provisioning could report success before its deferred database seed completed. The seed restore could also reuse a target embedded PostgreSQL process with another shutdown owner. This could stop the target database during the restore. **Expected behavior** Workspace status must show a failed deferred seed as a failure. The seed restore must own the target embedded PostgreSQL process until restore, migration, and validation finish. **Steps to reproduce** 1. Provision a worktree with deferred database seeding. 2. Make the seed manifest end in a failed state while the command exits with code 0. 3. Observe that the provision status remains successful on `master`. 4. Start a seed restore against an already-running target embedded PostgreSQL process. 5. Observe that another lifecycle owner can stop the target during restore. **Paperclip version or commit** `51a843e135` **Deployment mode** Local dev with execution workspaces and embedded PostgreSQL. ## What Changed - Add a first-class `workspace_seed` operation for deferred database seeds. - Require terminal, verified seed evidence before the seed operation succeeds. - Surface the seed phase and failure metadata in workspace status and UI state. - Give the seed process exclusive lifecycle ownership of the target embedded PostgreSQL process. - Suppress imported embedded-Postgres exit hooks without removing existing host listeners. - Record a credential-safe shutdown diagnostic in failed seed manifests. ## Verification - The original deferred-seed commit passed 4 server tests, 24 workspace-status UI tests, shared/server/UI typechecks, and the UI token gate. - The original PostgreSQL-lifecycle commit passed 3 lifecycle tests, 3 ownership/diagnostic tests, 1 real embedded-Postgres seed integration, and the affected package typechecks. - No local tests were rerun after the clean cherry-pick because the operator requested the shortest landing path. - Review the automatic PR checks for the clean `origin/master` replay. ## Risks - A live target database now causes an early error instead of being reused. The error includes recovery guidance. - Workspace consumers must handle the new `workspace_seed` operation type. Shared types and UI state handling are updated in this pull request. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.
