Deterministic seeded PRNG verifies NavigationStack invariants across
200k+ operations: depth >= 1, push/pop identity, forward cleared,
jump list only tracks detail screens, reset clears all, breadcrumbs
match depth, no panic under arbitrary sequences.
- 6 deterministic snapshot tests at 120x40 with FakeClock frozen at 2026-01-15T12:00:00Z
- Buffer-to-plaintext serializer resolving chars, graphemes, and wide-char continuations
- Golden file management with UPDATE_SNAPSHOTS=1 env var for regeneration
- Snapshot diff output on mismatch for easy debugging
- Tests: dashboard, issue list, issue detail, MR list, search results, empty state
- TERMINAL_COMPAT.md template for manual QA across iTerm2/tmux/Alacritty/kitty/WezTerm

mode tabs, input bar, result rendering, and hint bar
- Search screen: full-text search with result list and scoring display
- Timeline screen: chronological event feed with time-relative display
- Trace screen: file provenance chains with expand/collapse, rename
