# TASK-007: View commit history and changes

Status: planned — depends on TASK-006 and Codex TASK-009
Owner: Claude
Reviewer: Codex

## Outcome

A user can inspect commit history, changed files, per-commit patches, and comparisons between refs in a read-only interface.

## Writable paths

- `app/src/main/java/com/ubisam/ubgitea/feature/history/`
- `app/src/test/java/com/ubisam/ubgitea/feature/history/`
- `app/src/main/res/values/strings_history.xml`
- TASK-007 evidence only

Shared domain, data, Gradle, manifest, and navigation changes must be requested from Codex instead of edited by Claude.

## Acceptance criteria

- [ ] Commit history supports pagination and clearly identifies the active ref.
- [ ] Commit details show metadata and changed files without exposing private data in logs.
- [ ] Added, modified, renamed, and deleted files are distinguished.
- [ ] Large or truncated diffs are explicitly identified and bounded for mobile rendering.
- [ ] Ref comparisons validate and encode both refs independently.
- [ ] Tests cover change mapping, rename/delete behavior, pagination, truncation, and error states.
- [ ] Resource names use the `history_` prefix.
- [ ] Evidence records the exact reviewed TASK-009 contract-freeze commit.
