test(#143): Validate 50% rule prevents context exhaustion
Following TDD (Red-Green-Refactor):
- RED: Created comprehensive test suite with 12 test cases
- GREEN: Implemented validation logic that passes all tests
- All quality gates passed
Test Coverage:
- Oversized issue (120K) correctly rejected
- Properly sized issue (80K) correctly accepted
- Edge case at exactly 50% (100K) correctly accepted
- Sequential issues validated individually
- All agent types tested (opus, sonnet, haiku, glm, minimax)
- Edge cases covered (zero, very small, boundaries)
Implementation:
- src/validation.py: Pure validation function
- tests/test_fifty_percent_rule.py: 12 comprehensive tests
- docs/50-percent-rule-validation.md: Validation report
- 100% test coverage (14/14 statements)
- Type checking: PASS (mypy)
- Linting: PASS (ruff)
The 50% rule ensures no single issue exceeds 50% of target
agent's context limit, preventing context exhaustion while
allowing efficient capacity utilization.
Fixes #143
