## Thinking Path
> - Paperclip is an open source app that manages AI agents for work.
> - The server manages execution workspaces and their worktrees.
> - The terminal workspace reaper removes a workspace when its issue
tree reaches a terminal state.
> - Immediate removal prevents a person from reopening recently
completed work.
> - This pull request adds a configurable cooldown before the reaper
archives the workspace.
> - The cooldown keeps recent work available and keeps immediate cleanup
available with value `0`.
## Linked Issues or Issue Description
Refs: #7790
**Problem**
The reaper archives an execution workspace and deletes its worktree as
soon as the issue tree becomes terminal. A person cannot reopen recent
work without extra effort.
**Expected behavior**
The reaper should keep a recently completed workspace during a
configurable cooldown window. It should archive older work and support
immediate cleanup when the value is `0`.
**Proposed solution**
Read the cooldown from `PAPERCLIP_WORKSPACE_REAPER_COOLDOWN_DAYS`. Use a
seven-day default. Use the latest terminal timestamp in the source issue
tree as the cooldown anchor.
## What Changed
- Add `PAPERCLIP_WORKSPACE_REAPER_COOLDOWN_DAYS` with a seven-day
default.
- Treat `0` as no cooldown and use the default for negative or
non-numeric values.
- Use the latest `completedAt` or `cancelledAt` value in the source
issue tree.
- Use `updatedAt` when a terminal timestamp is null.
- Skip candidates inside the cooldown and report them in
`skippedCooldown`.
- Recheck the cutoff during the guarded archive operation.
- Document the environment variable and add focused tests.
## Verification
- Run `npx vitest run
server/src/__tests__/execution-workspaces-service.test.ts`.
- Confirm that the test run passes 66 tests.
- Confirm that the tests cover a recent tree, an old tree, value `0`,
and a null terminal timestamp.
- Confirm that the changed files pass `tsc --noEmit`.
## Risks
The default changes terminal workspace cleanup from immediate removal to
a seven-day delay. A value of `0` preserves immediate cleanup. The
guarded archive check limits race risk during concurrent lifecycle
changes.
