W2-2: Integration test for quickfix mode

[darksheer]

Quick Fix Mode — Wave 2, Item 2

Weight: M (15-40 turns)
Gate: none
Deps: W1-1 (#160)
Initiative: Quick Fix Mode

Task

Create comprehensive integration test for quickfix mode:

1. Create tests/test-quickfix-mode.sh

2. Test cases:

   • is_quickfix_mode returns 0 when .quickfix-mode exists and is fresh
   • is_quickfix_mode returns 1 when .quickfix-mode does not exist
   • is_quickfix_mode returns 1 when .quickfix-mode is older than 4h (mock with touch -t)
   • /quickfix skill creates the file when absent
   • /quickfix skill removes the file when present
   • session-end.sh removes .quickfix-mode
   • Safety-critical gates still deny in quickfix mode (nuclear deny, force-push)
   • Bypassed gates allow in quickfix mode (plan-check, @Decision, proof-gate)

3. Test sources core-lib.sh directly and mocks hook invocations

4. Follow existing test patterns in tests/ directory

Acceptance Criteria

• All 8 test cases pass
• Test cleans up after itself (no leftover .quickfix-mode files)
• Test can run in CI environment
• Test validates both bypass and non-bypass behavior

Critical Files

• tests/test-quickfix-mode.sh (new)
• hooks/core-lib.sh (sourced by test)
