## Thinking Path
> - Paperclip separates workspace provisioning lifecycle from whether
the work was actually delivered.
> - Git ancestry alone cannot recognize squash merges or deliveries into
a branch other than the workspace base.
> - A merged pull request linked from a terminal issue is stronger
delivery evidence for those cases.
> - The read contract should expose that evidence without changing
persisted workspace schema.
> - Cleanup must remain conservative: terminal descendants, delivered
work, and no active run checkout are all required.
> - Reusing the existing cleanup primitives keeps service shutdown,
lease cleanup, activity logging, and archival behavior consistent.
> - Focused regression coverage locks in both the honest read signal and
the fail-closed reaper guards.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
Execution workspace close-readiness payloads and terminal workspace
cleanup.
**Current behavior**
Delivered squash-merged or cross-branch workspaces can remain `active`
and report a permanent “not merged” warning because git ancestry does
not contain their original commits.
**Proposed behavior**
Read payloads distinguish PR-confirmed delivery, ancestry delivery,
unmerged work, and unknown state. Fully terminal delivered workspace
trees are archived only when no active run holds the checkout.
**Reason and benefit**
Operators and automation receive an honest delivery signal, while
shipped worktrees stop looking active forever and genuinely unmerged
work retains its warning.
**Breaking changes**
The workspace payload gains a derived field. Existing fields and
persistence remain unchanged; no database migration is required.
**What happened?**
A delivered workspace can remain `active` and warn that it is not merged
forever after its issue ships through a squash or cross-branch pull
request.
**Expected behavior**
Pull-request delivery should be represented honestly, and a fully
terminal delivered workspace should become cleanup-eligible when no run
holds its checkout.
**Steps to reproduce**
1. Create an issue workspace with commits ahead of its configured base.
2. Deliver those commits with a squash merge or into a different target
branch.
3. Mark the source issue and descendants done, then read workspace close
readiness.
Before this change, the workspace remains active with a “not merged”
warning indefinitely.
## What Changed
- Added the derived `deliveryState` workspace contract: `merged_via_pr`,
`merged_by_ancestry`, `unmerged`, or `unknown`.
- Extracted a shared GitHub pull-request merge classifier and reused it
for merge confirmations and workspace delivery checks.
- Suppressed false ancestry warnings when a terminal issue has
ground-truth merged-PR evidence.
- Added an idempotent terminality reaper with descendant-terminal,
active-run, and delivered-work guards.
- Restricted PR delivery evidence to the source issue, then required
live merged state plus matching GitHub repository, head branch, and
current workspace HEAD; persisted status, stale PRs, lexical mentions,
inbound references, and descendant PRs cannot authorize cleanup.
- Preserved workspaces with modified or untracked files even when their
committed HEAD was delivered.
- Bounded both long-lived pull-request state caches to 1,000 entries
with oldest-entry eviction.
- Routed eligible workspaces through existing runtime shutdown, lease
cleanup, activity logging, and archival machinery with exclusive Git
index, HEAD, and branch-ref locks plus non-forced removal.
- Added regression coverage for delivery derivation, warning behavior,
reaper guards, scheduler wiring, and squash/cross-branch delivery.

## Risks
The reaper intentionally fails closed when issue terminality,
pull-request state, git ancestry, or checkout ownership cannot be
proven. GitHub lookups can delay classification and cleanup but cannot
cause an unproven workspace to be archived. Automated terminal archival
holds exclusive Git index, HEAD, and branch-ref locks across validation
and removal, skips configured destructive hooks, and uses non-forced
removal so dirty writes fail closed. Reopening a source issue does not
restore an archived workspace; it emits an audit event so a human or
agent can re-provision explicitly.
## Model Used
OpenAI Codex, GPT-5. The runtime did not expose a more specific model ID
or context-window size. Reasoning, tool use, repository editing, test
execution, and GitHub CLI access were enabled.

## Thinking Path
> - Paperclip agents do real work in project and execution workspaces.
> - Operators need workspace state to be visible, navigable, and
copyable without digging through raw run logs.
> - The branch included related workspace cards, navigation, runtime
controls, stale-service handling, and issue-property visibility.
> - These changes share the workspace UI and runtime-control surfaces
and can stand alone from unrelated access/profile work.
> - This pull request groups the workspace experience changes into one
standalone branch.
> - The benefit is a clearer workspace overview, better metadata copy
flows, and more accurate runtime service controls.
## What Changed
- Polished project workspace summary cards and made workspace metadata
copyable.
- Added a workspace navigation overview and extracted reusable project
workspace content.
- Squared and polished the execution workspace configuration page.
- Fixed stale workspace command matching and hid stopped stale services
in runtime controls.
- Showed live workspace service context in issue properties.
## Verification
- `pnpm install --frozen-lockfile`
- `pnpm exec vitest run
ui/src/components/ProjectWorkspaceSummaryCard.test.tsx
ui/src/lib/project-workspaces-tab.test.ts
ui/src/components/Sidebar.test.tsx
ui/src/components/WorkspaceRuntimeControls.test.tsx
ui/src/components/IssueProperties.test.tsx`
- `pnpm exec vitest run packages/shared/src/workspace-commands.test.ts
--config /dev/null` because the root Vitest project config does not
currently include `packages/shared` tests.
- Split integration check: merged after runtime/governance,
dev-infra/backups, and access/profiles with no merge conflicts.
- Confirmed this branch does not include `pnpm-lock.yaml`.
## Risks
- Medium risk: touches workspace navigation, runtime controls, and issue
property rendering.
- Visual layout changes may need browser QA, especially around smaller
screens and dense workspace metadata.
- No database migrations are included.
> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.
## Model Used
- OpenAI Codex, GPT-5.4 tool-enabled coding model, agentic
code-editing/runtime with local shell and GitHub CLI access; exact
context window and reasoning mode are not exposed by the Paperclip
harness.
