scorecard: chấm live 2 mục hardcode; pipeline: fallback real + honest scoring doc

Hướng A — scorecard.sh (video demo):
- h5_1 approval workflow: hardcode 0 → governance-check deploy live (approval_required)
- h6_2 hallucination rate: hardcode 0 → hallucination-scan phân biệt dirty>clean live
- "N/5 mục" chuyển từ text cứng sang đếm động
- H4/H5/H6 → 100/100 (5/5 gate live), Average 57.9 → 90.0

Hướng B — run-casan-pipeline.mjs:
- fallback: stub 'exit 9' → 'cat /nonexistent' (real failure, nhất quán adversarial T3)
- drift: giữ so fallback-output vs golden (clean run=1.0); năng lực phát hiện
  drift thật chứng minh ở adversarial suite
- Full 12-step run verify: H1 CONTEXT_VALID=24, H2 tool-audit records=25 signed,
  H5 audit-chain records=22 signed, H6 provider_telemetry per-step thật, H7 rollback real

phase3-real-run-scoring.md: giải thích vì sao scorecard cũ cho H5=60/H6=80
(hardcode), phân biệt scorecard-90 vs re-score-84 (2 mục đích khác nhau).

Verify: adversarial 44/0, security-gate 11/0/0, pipeline 12 steps OK.
