Dotta 4a641d0980 fix(ui): default human task replies to the latest assigning agent (#15594)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Tasks let agents ask a person for input.
> - The reply composer needs a useful default recipient.
> - A recent comment does not identify the agent that assigned the task.
> - The old fallback can select the person who is writing the reply.
> - This change uses the latest agent assignment and keeps manual
choices.

## Linked Issues or Issue Description

**What happened?**
When an agent assigns a task to a person, the reply composer can select
that person or a different commenter. A data refresh can also replace a
manual selection.

**Expected behavior**
For a task assigned to the current person, select the latest agent that
assigned it to them. If no such assignment exists, use the latest other
commenter. If neither exists, leave the recipient empty. Keep explicit
choices during refreshes.

**Steps to reproduce**
1. Have agent Alpha assign a task to a person.
2. Assign it to agent Beta, then have Beta assign it to the same person.
3. Open the task as that person.
4. Check that the reply composer selects Beta.
5. Select another recipient. Refresh task data. Check that the selection
stays.

Related work: #15091 shares task composer controls. This change fixes
recipient defaults.

## What Changed

- Read real assignment changes from REST and native runner task
activity, in time order.
- Record human assignee fields in native create and reassign activity.
- Ignore unchanged assignment fields and assignments to other people.
- Use the assigning agent before comment hints for human-owned tasks.
- Connect the suggestion to current and classic task composers and
pipeline replies.
- Keep manual selections when suggestions change.
- Add regression tests and document the fallback.
- Use tasks with no assignee in the attachment receipt tests. This keeps
the tests on the comment route. Dismiss announcements through the real
UI.
- Record human and agent assignees in REST creation receipts. Include
child creation in the assignment history resolver.

## Verification

- Focused tests cover assignment order, creation, other recipients,
unchanged fields, fallback, and manual selections.
- Browser fixture uses the real composer and assignment resolver. It
selects Beta and keeps a manual human selection after history refresh.
- Passed: 223 focused tests across four suites.
- Passed: `pnpm --filter @paperclipai/ui typecheck`.
- Passed: `pnpm --filter @paperclipai/ui build`.
- Passed: `pnpm check:token-gates`.
- The initial CI run passed full build, typecheck, Rust, unit tests and
seven E2E shards. The attachment shard exposed tests that relied on the
old self-selection default. The tests now select the recipient
explicitly.
- Native assignment regression tests and resolver tests pass: 40 tests.
- Attachment E2E suite: 10 passed; one page-load timing failure passed
on an isolated rerun. All 11 cases passed across the suite and rerun.
- Previous full CI passed at cc7ed05. New CI must pass on the current
head.
- Latest local checks: 16 resolver tests and 7 workspace policy tests
pass. REST creation audit tests cover both creation routes.
- The latest browser check could not start. The UI build exceeded the
local memory limit (exit 137). Full typecheck, tests, build, and browser
checks will run in CI.

## Risks

- Old activity rows without previous assignment values cannot prove a
reassignment. They use the comment fallback.
- An empty fallback requires the person to choose a recipient or use the
existing no-assignee flow.
- No database or API schema changes.

## Model Used

OpenAI Codex, GPT-6. The session does not expose an exact model build or
context window. Used code editing, shell tools, tests, and browser
verification.

## Checklist

- [x] I have included a thinking path that traces from project context
to this change
- [x] I have specified the model used (with version and capability
details)
- [x] I have checked ROADMAP.md and confirmed this PR does not duplicate
planned core work
- [x] I have searched GitHub for duplicate or related PRs and linked
them above
- [x] I have either (a) linked existing issues with `Fixes: #` / `Closes
#` / `Refs #` OR (b) described the issue in-PR following the relevant
issue template
- [x] I have not referenced internal/instance-local Paperclip issues or
links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip`
URLs)
- [x] My branch name describes the change (e.g. `docs/...`, `fix/...`)
and contains no internal Paperclip ticket id or instance-derived details
- [x] I have run tests locally and they pass
- [x] I have added or updated tests where applicable
- [x] I have updated relevant documentation to reflect my changes
- [x] I have considered and documented any risks above
- [x] All Paperclip CI gates are green
- [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups
- [x] I will address all Greptile and reviewer comments before
requesting merge


Final validation at f83f2f6: 55 checks passed. Two optional Storybook
checks were skipped. All browser shards passed. Both review threads are
resolved. Classic attachment tests use the real no-assignee
confirmation.
