Devin FoleyandPaperclip 6c198d616e fix(issues): preserve human handoffs from the active agent run (#16082)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Tasks have one owner, and the server records assignment changes.
> - An agent can finish its work by handing the task to a human for
review.
> - The assignment route stops the active run before it saves that
handoff.
> - When the caller is that run, a slow workspace restore can exceed the
stop timeout and prevent the assignment from saving.
> - Recovery can then mark the task Blocked while its comment says the
handoff succeeded.
> - This pull request lets the authenticated legacy run save a human
handoff and finish its turn normally.
> - Other actors and transfers to executable agents keep the verified
stop requirement.

## Linked Issues or Issue Description

Refs #13730. Related: #13782, #14700, and #15094.

**What happened?**

An agent posted its review handoff, then sent `PATCH /api/issues/{id}`
to assign the task to its human creator with status `in_review`. The
route cancelled that same run before saving the assignment. Workspace
restore took 66 seconds. The stop limit is 60 seconds. The assignment
never committed. Recovery marked the task Blocked, and it stayed
assigned to the agent.

**Expected behavior**

The authenticated active legacy run can hand its own task to a human and
finish normally. The human assignment and requested review status must
save without waiting for workspace restore. Native runs, board
reassignment, agent API keys, and transfers to another agent still
require a verified stop.

**Steps to reproduce**

1. Run a legacy agent on its assigned task with a signed run token.
2. Send a task PATCH from that run with a human `assigneeUserId`, a null
`assigneeAgentId`, and status `in_review`.
3. Make stopping the sandbox take more than 60 seconds. Before this fix,
the handoff fails before the task update. With this fix, the update
saves and the run finishes normally.

**Paperclip version or commit**

Reproduced in hosted execution. The patch is based on master at
`56a0bf0d492`.

**Deployment mode**

Hosted authenticated server with a legacy agent in a remote sandbox. The
same route serves local deployments.

PR #13782 proposes a broader exemption for all self-handoffs. This
focused change limits the exemption to human recipients and legacy runs.
It checks the exact active run, agent, company, and task, and it retains
the stop requirement before an executable successor can take ownership.
PRs #14700 and #15094 address later wake and recovery behavior after a
reassignment stop.

## What Changed

- Skip the reassignment cancellation only for an authenticated legacy
run handing its own task to a human.
- Reject later mutations from the outgoing run against its human-owned
task, both in route authorization and under the update transaction
locks.
- Keep assignment permission checks, goal control, and queued human
response protection.
- Add route regressions for slow stops, active-run lookup, actor and
runtime boundaries, recipient types, permission denials, and follow-up
edits, completion, and reassignment.
- Update the real HTTP low-trust handoff test to prove the run stays
alive, its late edit fails, and the human wake receipt remains
invalidated.
- Add Postgres tests for saved assignment, former-owner rejection, and
review state after the outgoing run succeeds or fails.
- Document the handoff rule and update the task feature and agent access
maps.

## Verification

- 328 relevant tests passed across the route, issue service, low-trust
HTTP, and legacy recovery suites. The route suite passed all 160 tests,
and all 13 low-trust HTTP tests passed after updating the obsolete
cancellation expectation.
- Removing the production guard makes both slow-shutdown handoff
regressions fail with HTTP 500.
- `pnpm -r typecheck` passed.
- `pnpm build` passed.
- `node scripts/check-maps.mjs` passed.
- `git diff --check` passed.
- All 54 current-head checks passed; 2 optional Storybook checks were
skipped. The CI lanes cover the full Vitest suite, typecheck/build,
Runner checks, and product E2E checks.
- Apex reviewed `c68fbfb356c3d80eb7136babb49940709a3c3459` at 5/5 with
no findings; both earlier review threads are resolved.
- The complete test lanes passed in CI. The duplicate local full `pnpm
test:run` was stopped after CI completed; it did not finish locally. All
328 focused local tests and full local typecheck/build passed.

## Risks

- The outgoing legacy turn stays alive after the human takes ownership.
Route and transactional ownership checks reject its later mutations of
the human-owned task. Read and comment access follows normal policy.
Goal control still runs before the handoff.
- This exemption does not apply to native runs or another agent as
recipient. Those paths still stop the old execution before assignment.
- This fix prevents future failed handoffs. It does not infer or replay
old assignment requests.
- There is no schema change or API shape change.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, repository tools, and code
execution. The session does not expose a more specific runtime model ID
or context window size.

Raw Blame History

Task creation and lifecycle

People create, assign, organize, discuss, and finish tasks. A task retains its owner, project, priority, history, and outputs as it moves through the work lifecycle.

Implementation: new task, task list, task detail.

Agent access: companion.

Sub-features

  • create: capture a title/request with the intended agent, project, and attachments.
  • organize: filter, sort, group, and navigate tasks without losing the selected context.
  • properties: change status, priority, assignee, project, and relationships where authorized.
  • discussion: persist comments, references, and files on the task.
  • completion: distinguish backlog, active work, review, blocked, done, and cancelled outcomes.

How to get to it (user POV)

new-task

Use New task from the global launcher, task list, or project task view.

task-list

Open /issues or a project’s Issues view; legacy /tasks links redirect.

task-detail

Open /issues/:issueId from a row, mention, or direct link.

Driving it with Playwright and the Paperclip CLI

Preconditions: follow the baseline. Use a disposable project. Persistence checks can assign work to Me or leave it unassigned; execution checks additionally need an invokable test agent. Record whether a real or simulated harness handles execution.

new-task

Automated: creation dialog is component coverage with mocked requests.

Manual: Create a uniquely named task with an agent and project. Open its resulting link and reload. Confirm text, attachment, assignment, and project persisted, and verify execution started only when the task and agent are eligible.

Creation is request-first: enter Describe a task…, choose the assignee and project, and submit Create task. A standalone title field is not always shown. Use a human/unassigned task to verify persistence without invoking a model.

task-list

Automated: task-list helpers cover search URLs, pagination, deduplication, and presentation constants. The suite does not render the page or exercise filtering, grouping, opening a task, and returning; those interactions still need a running-browser check.

Manual: Filter by status and assignee, change grouping/sort, open a task, and return. Verify the correct records and selected view survive navigation and reload. Include an empty result and a failed request.

task-detail

Automated: task detail covers component behavior, while issue service covers server contracts.

Manual: For a disposable task owned by a legacy agent, have its current run assign the task to a human with status In review. Verify that assignment and status persist, that the current run finishes without issue_reassigned, and that slow workspace restoration does not turn the task Blocked. Try a later edit from the outgoing run and verify rejection. Repeat a board reassignment and confirm that the outgoing run still stops.

Manual: Add a comment and edit authorized properties. Reload and verify history, actor, and values. Complete a disposable task and inspect its deliverable; reopen through an available action and confirm the next execution follows current policy.

Gotchas

  • Priority remains an API field, but ordinary priority UI editing is hidden.

  • A status label alone does not prove that the requested work exists.

  • Single-assignee and atomic checkout rules still apply when tasks are created from different hosts.

  • Use coordination, steering, and documents for their distinct workflows.
