16 tasks across 4 phases, each with explicit Red-Green-Refactor TDD steps: - Phase 1 (1.1-1.16): Library + dry-run. 20 unit tests across categorizer, batcher, plugin. New run_tests_batched.py has --plan/--audit only. - Phase 2 (2.1-2.3): Shadow run via CI. Compare new vs old plan output. - Phase 3 (3.1-3.4): Switch default. Full CLI with --tiers, --durations. Old script becomes .legacy. Update docs/guide_testing.md. - Phase 4 (4.1-4.6): Populate registry, gitignore durations, delete legacy, archive track. 1-space indentation per project style guide. No placeholders. All test code is concrete.
