"""
Rolling-up scenario (SC) L3 execution coverage for the CFC traceability matrix.

Root-cause fix for gaps G-4 / G-9 (execution evidence was never recorded or
rolled up -> frozen "15/243" in tests/TRACEABILITY-MATRIX.md §4 L3).

This script is the single, re-runnable source that turns raw test execution
into a per-SC L3 status and writes it back to:
  - docs/tdd/test/scenario-execution-ledger.json   (the living evidence ledger)
  - tests/TRACEABILITY-MATRIX.md                    (§1 / §4 L3 lines)
  - docs/tdd/test/automation-status.md              (scenario line + note)

Inputs (all read-only except the two outputs above):
  - tests/test-cases/*.md            SC<-TC links via "所属场景" column
  - .tdd/test-progress.json          per-TC execution status (pass/executed/...)
  - FRESH_EVIDENCE (below)           fresh, verified R212/R215 + matrix §2 runs

Status priority per SC: pass > executed > fail > blocked > needs_script > unknown
