## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Paperclip gives operators a summary for each workspace.
> - An execution workspace detail page used the parent project-workspace
summary slot.
> - Two execution workspaces under one project workspace could therefore
show the same summary.
> - This pull request gives each execution workspace its own summary
scope.
> - It also limits the summary snapshot and generated issue to that
execution workspace.
> - The benefit is that a new or parallel execution workspace cannot
inherit unrelated status.
## Linked Issues or Issue Description
**What happened?**
An execution workspace detail page read and refreshed the summary slot
for its parent project workspace. Parallel execution workspaces could
show the same status and include issues from each other.
**Expected behavior**
Each execution workspace must have one isolated summary slot. Its
generated snapshot must include only issues assigned to that execution
workspace.
**Steps to reproduce**
1. Create two execution workspaces under one project workspace.
2. Add different issues to each execution workspace.
3. Generate the summary in the first execution workspace.
4. Open the second execution workspace.
5. Observe that the old implementation could reuse the first summary.
**Paperclip version or commit**
The problem exists on `master` before this pull request.
**Deployment mode**
The issue affects both local trusted and authenticated deployments.
## What Changed
- Added `execution_workspace` to the shared summary-slot scope contract.
- Validated execution-workspace ownership and stored generated summary
issues on the correct execution workspace.
- Limited execution-workspace snapshots to issues with the matching
execution workspace ID.
- Updated the execution workspace page to use its own summary slot.
- Updated Summarizer instructions, routine options, catalog metadata,
documentation, and regression tests.
## Verification
- `NODE_ENV=test pnpm exec vitest run
packages/shared/src/summary-slot.test.ts
server/src/__tests__/summary-slots.test.ts
ui/src/pages/ExecutionWorkspaceDetail.test.tsx` — 30 focused tests
passed; the embedded-Postgres server tests were run outside the
process-restricted sandbox.
- `pnpm check:token-gates` — passed.
- `pnpm --filter @paperclipai/skills-catalog validate` — passed with 17
catalog skills.
- [Latest-head GitHub
Actions](https://github.com/paperclipai/paperclip/actions/runs/31491475405)
— all 22 jobs passed on `beea14cbaf`, including typecheck, build,
server/workspace tests, serialized suites, e2e, canary, and aggregate
verification. One unrelated adapter cleanup test initially hit an
`ENOTEMPTY` temp-directory race; its single permitted rerun passed.
- Greptile — 5/5 confidence on `beea14cbaf`, 12 files reviewed, zero
comments added, and zero unresolved threads.
## Risks
- Low risk. The new scope is additive.
- Existing project and project-workspace summary slots keep their
current keys and behavior.
- A summary generated for an execution workspace now excludes sibling
workspace issues by design.
> 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 with GPT-5. The deployment does not expose a more
specific model ID or context-window value. It used agentic reasoning,
repository tools, code execution, and GitHub tooling.
