Consolidates

• test(unit): Add tests for unleashed-danger.py #1 — test(unit): Add tests for unleashed-danger.py
• test(integration): Complete unleashed.py pending scenarios #2 — test(integration): Complete unleashed.py pending scenarios
• chore: Add automated tests for core pattern matching and key handling #16 — chore: Add automated tests for core pattern matching and key handling

Scope

1. Unit tests — pattern matching (PERMISSION_PATTERNS, MODEL_PAUSE_PATTERNS), ANSI stripping (strip_ansi, mirror_strip_ansi), key mapping (VK_MAP), surrogate normalization
2. Integration tests — PTY spawn, approval flow, transcript save, mirror/friction logger output
3. unleashed-danger.py — approval without safeguards, edge cases

Notes

• research: How does the Claude Code team test their TUI? Terminal wrapper approaches #14 (research: how does Claude Code team test their TUI?) is labeled discuss and informs the approach here
• Consider pytest with mock PTY for unit tests, real PTY for integration
• Pattern matching tests are high value — they catch regressions when Claude Code updates their UI
