+# Implementation Plan: Test Regression Verification (test_regression_verification_20260307)
+
+> **Reference:** [Spec](./spec.md)
+
+## Phase 1: Test Discovery
+Focus: Find all test files
+
+- [ ] Task 1.1: List all test files
+    - Run: `pytest --collect-only`
+    - Document test count
+
+## Phase 2: Run Tests
+Focus: Execute full test suite
+
+- [ ] Task 2.1: Run unit tests (models, conductor)
+- [ ] Task 2.2: Run GUI tests
+- [ ] Task 2.3: Run integration tests
+
+## Phase 3: Analyze Results
+Focus: Review test outcomes
+
+- [ ] Task 3.1: Document pass/fail counts
+- [ ] Task 3.2: Identify any failures
+- [ ] Task 3.3: Determine if regressions or pre-existing
+
+## Phase 4: Fix Failures (if any)
+Focus: Resolve test issues
+
+- [ ] Task 4.1: Fix regressions from recent changes
+- [ ] Task 4.2: Document pre-existing failures
+
+## Phase 5: Verification
+Focus: Confirm 0 regressions
+
+- [ ] Task 5.1: Re-run tests after fixes
+- [ ] Task 5.2: Final verification

+# Track Specification: Test Regression Verification (test_regression_verification_20260307)
+
+## Overview
+Verify that all existing tests pass with 0 regressions after recent track implementations (Kill/Abort, Block/Unblock, Pause/Resume, Per-Ticket Model Override).
+
+## Recent Changes
+
+### Tracks Implemented Recently
+1. **Kill/Abort Running Workers** - Added worker termination with abort events
+2. **Manual Block/Unblock Control** - Added manual block with cascade
+3. **Pipeline Pause/Resume** - Added global pause/resume
+4. **Per-Ticket Model Override** - Added model selection per ticket
+
+## Current Test Status
+
+### Known Test Files
+- tests/test_conductor_engine_abort.py
+- tests/test_conductor_abort_event.py
+- tests/test_run_worker_lifecycle_abort.py
+- tests/test_gui_kill_button.py
+- tests/test_manual_block.py
+- tests/test_pipeline_pause.py
+- tests/test_per_ticket_model.py
+- And many more in tests/
+
+## Requirements
+
+### FR1: Full Test Suite Run
+- Run ALL tests in tests/ directory
+- Verify no regressions introduced
+
+### FR2: Test Categories
+- Unit tests for models, conductor, gui
+- Integration tests (if any)
+- Simulation tests
+
+### FR3: Fix Any Failures
+- If tests fail, investigate and fix
+- Document any pre-existing failures
+
+### FR4: Test Coverage Verification
+- Ensure new features have test coverage
+
+## Acceptance Criteria
+- [ ] All tests pass
+- [ ] No new regressions
+- [ ] Test results documented
