# TASK-010: Implement pull-request and issue API contracts

Status: planned — depends on TASK-004
Owner: Codex
Reviewer: Claude

## Outcome

Provide frozen read-only domain and data contracts for pull requests, issues, reviews, and comments so Claude can implement TASK-008 without editing shared layers.

## Writable paths

- `app/src/main/java/com/ubisam/ubgitea/domain/workitems/`
- `app/src/main/java/com/ubisam/ubgitea/data/workitems/`
- `app/src/test/java/com/ubisam/ubgitea/domain/workitems/`
- `app/src/test/java/com/ubisam/ubgitea/data/workitems/`
- `tasks/010-work-items-api-contract.md`

## Acceptance criteria

- [ ] Pull requests and issues use separate immutable domain models.
- [ ] Lists, reviews, and comments have explicit immutable pagination contracts.
- [ ] Nullable or deleted authors map without crashes or invented identity.
- [ ] 401, 403, 404, 422, rate-limit, network, parse, and server failures map to typed results.
- [ ] Endpoint DTOs remain outside domain and UI packages.
- [ ] Representative JSON and fake-server tests cover lists, reviews, comments, deleted users, pagination, and failures.
- [ ] No create, edit, merge, close, comment, or notification-write endpoint is exposed.
- [ ] Evidence records the reviewed contract-freeze commit for TASK-008.
