## 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.

**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.

**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.

## Model Used
- OpenAI Codex, GPT-5, high-reasoning mode, with repository, shell, and
GitHub tool use. The runtime does not expose a more specific deployment
suffix or context-window value.
