## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Isolated workspaces give each task a safe and reproducible checkout.
> - The existing setup cloned the development database before an agent
needed to run the app.
> - This made worktree creation slower and heavier for tasks that never
start a service.
> - Runtime services already use one server start path for heartbeat,
operator, and startup recovery flows.
> - This pull request moves heavy setup to that start path and keeps
worktree creation lean.
> - The benefit is faster isolated workspace creation with the same
reliable runtime setup when a service starts.
## Linked Issues or Issue Description
Related pull request: #10652 covers the initial deferred
database-seeding slice. This pull request supersedes it with end-to-end
runtime provisioning and safe cleanup.
**What existing behavior does this improve?**
This improves isolated worktree creation, runtime service startup, and
isolated instance cleanup.
**Subsystem affected**
Cross-cutting: CLI worktree setup, server runtime orchestration, shared
workspace contracts, and development scripts.
**Current behavior**
Paperclip seeds an isolated development database during worktree
creation. It can also leave an isolated instance directory after
workspace teardown. This work happens even when no runtime service
starts.
**Proposed behavior**
Paperclip creates the worktree with a lean eager setup. It runs an
idempotent runtime provision command before the first managed service
spawn. Concurrent starts share one provision attempt. Teardown removes
the isolated instance safely.
**Reason and benefit**
Many agent tasks only edit and test code. They do not need a running
Paperclip instance. Deferring the database seed reduces workspace
startup cost while preserving automatic setup for tasks that start the
app.
**Breaking changes**
None. The new runtime provision command is optional. Existing workspace
behavior is unchanged when it is absent.
## What Changed
- Split Paperclip worktree setup into a lean eager script and an
idempotent runtime provision script.
- Added `runtimeProvisionCommand` to project, issue, realized workspace,
and persisted workspace contracts.
- Added a per-workspace provision mutex before local service spawn for
heartbeat, operator, and startup recovery flows.
- Added a persisted `provisioning` service state and the
`workspace_runtime_provision` operation phase.
- Kept provision time outside the service readiness timeout and made
failed attempts visible and retryable.
- Reclaimed isolated instance data during safe workspace teardown.
- Serialized deferred database seeding across processes and bound
teardown to the instance root captured in persisted workspace metadata.
- Added tests for config flow, concurrency, retry, no-op behavior,
readiness timing, scripts, CLI commands, and cleanup.
- Documented the eager and runtime provisioning contracts.
## Verification
- `pnpm -r typecheck`
- `pnpm build`
- `pnpm test:run` (server: 3,201 passed; UI: 3,345 passed; the CLI phase
exposed one environment-sensitive AWS doctor assertion because the agent
runtime injects static AWS credentials)
- `env -u AWS_ACCESS_KEY_ID -u AWS_SECRET_ACCESS_KEY pnpm exec vitest
run cli/src/__tests__/secrets.test.ts -t 'passes AWS doctor checks when
non-secret provider config is present'`
- Focused runtime tests cover serialized provisioning, retry after
stderr failure, absent-command no-op behavior, operation logging,
persisted state order, and readiness timeout exclusion.
- Focused CLI and cleanup tests cover concurrent seed serialization,
stale-lock fail-closed behavior, persisted instance ownership, and
rewritten sibling pointers.
## Risks
- A faulty runtime provision script blocks service startup. Paperclip
records stderr, marks the service failed, and retries on the next start.
- Concurrent service requests share an in-process provision attempt,
while the seed command uses an atomic filesystem lock across processes.
A stale lock fails closed and requires an operator to verify no seed is
running before removing it.
- Isolated instance cleanup is destructive. The cleanup service
validates ownership and path containment before removal.

## Model Used
- OpenAI Codex, `gpt-5.6-sol`, with agentic reasoning, tool use, and
code execution. The service does not expose the context-window size.
