"""Empirical test implementation for TRACE_TEST_PLAN.md.

Phase 1 unit tests: TEST-01, TEST-03, TEST-05, TEST-09, TEST-11, TEST-12.
Phase 2 trace-infra tests: TEST-02, TEST-06, TEST-08.
Each test is a function that prints structured JSON results.
Run the whole file or individual tests via --test flag.

Usage:
    python tests/test_trace_plan.py                  # run all
    python tests/test_trace_plan.py --test 01        # run TEST-01 only
    python tests/test_trace_plan.py --test 01 03 05  # run selected
    python tests/test_trace_plan.py --test 02 06 08  # run Phase 2
