## Thinking Path
> - Paperclip lets people manage agent work from tasks.
> - Agents can request app access in a task card.
> - Some apps first require Paperclip Cloud enrollment.
> - Enrollment could leave the task, and OAuth could lose the task
interaction ID.
> - This PR keeps enrollment in a separate window and retains the
interaction ID through OAuth.
> - The task can then recognize the connection and continue
automatically.
## Linked Issues or Issue Description
**What happened?**
A first Gmail connection could leave the task dialog during Cloud
enrollment. Setup resumed on the Apps page. Gmail connected, but the
task card could remain pending because OAuth did not retain its
interaction ID.
**Expected behavior**
Keep the task open and preserve its access choices. Resolve the card
after the server verifies connection access. Continue the agent
automatically.
**Steps to reproduce**
1. Start a fresh source test-drive instance without Cloud enrollment.
2. Ask an agent to read Gmail.
3. Open Connect on the task card.
4. Complete Cloud enrollment and Gmail authorization.
5. Check whether the task card updates without selecting the connection
again.
**Paperclip version or commit**
Reproduced on 35fdc0c66b. This branch
applies the fix to current master.
**Deployment mode**
Source test-drive in local-trusted mode. The shared setup code also
serves authenticated instances; live authenticated acceptance was not
performed.
Related PRs: #13058 introduced task connections. #12943 repaired expired
enrollment links. #12906 concerns Composio service matching and does not
fix this OAuth handoff.
## What Changed
- Open task enrollment in a reserved window, with a new-tab fallback.
- Refresh server enrollment status and the provider catalog while
keeping the task dialog and access choices.
- Return the enrollment callback to the verified task when available.
- Retain the interaction ID when OAuth resumes from the page host.
- Clear the server capability cache after enrollment and reject stale
cache writes.
- Close reserved popups on enrollment errors and invalid authorization
URLs.
- Add callback and setup regression tests, including blocked popups.
Update connection-intent documentation.
## Verification
- All 176 focused connector, enrollment, callback, OAuth, and setup
tests pass.
- Greptile gives commit `e58da6662` a 5/5 score. Both review threads are
resolved.
- `pnpm check:token-gates`, `pnpm build`, and `pnpm -r typecheck` pass.
- All CI checks pass for `e58da6662`, including the full test matrix,
browser tests, Runner verification, release registry, and canary dry
run.
- The serial local `pnpm test:run` was stopped after the complete CI
test matrix passed. It is not counted as a full local pass.
- Live browser test: fresh instance, native Codex runner, Gmail
read-only access, and a real Google account.
- Enrollment preserved the task dialog. The card changed to connected
and the agent called Gmail search and message-read tools without another
message or Run click.
- The connected card persisted after refresh. Google reused existing
consent during this attempt.
- The runner displayed only its completion summary. Full answer delivery
is a separate issue and is outside this PR.
## Risks
- Browsers can block or isolate authorization windows. The new-tab
fallback remains available, and the parent checks server state.
- Enrollment completion is only a prerequisite. It does not grant access
or resolve the task card by itself.
- No database migration, runner lifecycle change, or recovery UI is
included.
## Model Used
OpenAI Codex (GPT-6), with code editing, shell tools, and browser
automation. The session does not expose an exact runtime model ID or
context-window size.
