# TASK-007: View commit history and changes

Status: planned — depends on TASK-004 and TASK-006
Owner: Codex
Reviewer: Claude

## Outcome

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

## 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.
