# TASK-006: Browse trees and source code by ref

Status: planned — depends on TASK-005
Owner: Codex
Reviewer: Claude

## Outcome

A user can navigate directories and view source files at an explicit branch, tag, or commit without silently changing refs.

## Acceptance criteria

- [ ] Repository, selected ref, and current path remain visible.
- [ ] Directory navigation is deterministic and safely handles encoded names.
- [ ] Text files render with bounded memory use and copy support.
- [ ] Binary, Git LFS, submodule, unsupported encoding, and oversized-file states have explicit fallbacks.
- [ ] Loading, empty, offline, authentication-expired, not-found, and server-error states are localized and accessible.
- [ ] Tests cover ref preservation, path navigation, content classification, and size limits.
