Implement session rotation that spawns fresh agents when context reaches
95% threshold.
TDD Process:
1. RED: Write comprehensive tests (all initially fail)
2. GREEN: Implement trigger_rotation method (all tests pass)
Changes:
- Add SessionRotation dataclass to track rotation metrics
- Implement trigger_rotation method in ContextMonitor
- Add 6 new unit tests covering all acceptance criteria
Rotation process:
1. Get current context usage metrics
2. Close current agent session
3. Spawn new agent with same type
4. Transfer next issue to new agent
5. Log rotation event with metrics
Test Results:
- All 47 tests pass (34 context_monitor + 13 context_compaction)
- 97% coverage on context_monitor.py (exceeds 85% requirement)
- 97% coverage on context_compaction.py (exceeds 85% requirement)
Prevents context exhaustion by starting fresh when compaction is insufficient.
Acceptance Criteria (All Met):
✓ Rotation triggered at 95% context threshold
✓ Current session closed cleanly
✓ New agent spawned with same type
✓ Next issue transferred to new agent
✓ Rotation logged with session IDs and context metrics
✓ Unit tests with 85%+ coverage

Add comprehensive test suite for OrchestrationLoop class that integrates:
- Queue processing with priority sorting
- Agent assignment (50% rule)
- Quality gate verification on completion claims
- Rejection handling with forced continuation prompts
- Context monitoring during agent execution
- Lifecycle management (start/stop)
- Error handling for all edge cases

Fixed code review findings:
- Removed unused imports (AsyncMock, MagicMock)
- Fixed line length violation in test_forced_continuation.py
All 15 tests still passing after fixes.
Implement comprehensive test suite for four core quality gates:
- BuildGate: Tests mypy type checking enforcement
- LintGate: Tests ruff linting with warnings as failures
- TestGate: Tests pytest execution requiring 100% pass rate
- CoverageGate: Tests coverage enforcement with 85% minimum
All tests follow TDD methodology - written before implementation.
Total: 36 tests covering success, failure, and edge cases.

Add comprehensive cost optimization test scenarios and validation report.
Test Scenarios Added (10 new tests):
- Low difficulty assigns to MiniMax/GLM (free agents)
- Medium difficulty assigns to GLM when within capacity
- High difficulty assigns to Opus (only capable agent)
- Oversized issues rejected with actionable error
- Boundary conditions at capacity limits
- Aggregate cost optimization across all scenarios
Results:
- All 33 tests passing (23 existing + 10 new)
- 100% coverage of agent_assignment.py (36/36 statements)
- Cost savings validation: 50%+ in aggregate scenarios
- Real-world projection: 70%+ savings with typical workload
Documentation:
- Created cost-optimization-validation.md with detailed analysis
- Documents cost savings for each scenario
- Validates all acceptance criteria from COORD-006
Completes Phase 2 (M4.1-Coordinator) testing requirements.

- Integration with QueueManager from #159
- Active agent tracking for future agent management
Configuration settings added:
- COORDINATOR_POLL_INTERVAL (default: 5.0s)
- COORDINATOR_MAX_CONCURRENT_AGENTS (default: 10)
- COORDINATOR_ENABLED (default: true)
Tests: 27 new tests covering all acceptance criteria
Coverage: 92% overall (100% for coordinator.py)
