docs: re-score from a real full run (155/0) after H5 hardening
Ran all 7 suites sequentially on 2026-07-04 @ 00aabfa with Vault dev live so KMS
runs (not skips): run-casan4 35 · adversarial 44 · phase1-track-a 25 ·
phase2-track-c 29 · phase3-evidence 7 · phase-h5-approval 8 · phase-h5-infra 7
= 155 PASS / 0 FAIL; security-gate PASS=11 FAIL=0.
- scoring-run-report.md: fair re-score — H5 76→80 (approval-identity + KMS live
rotate/non-exportable + WORM), lowest harness now H6=79, avg ~80.7/100, Level 4.
Evidence lists the live KMS + WORM results.
- CASAN_HARDENING_STATUS.md: new Phase 4 (C4 approval-identity, B3 KMS, C5 WORM =
implemented+tested); test inventory 140→155 (7 suites); planned→partial for
KMS/approval/WORM with honest remaining gaps (live IdP, S3 WORM store, KMS default).
- Plan-07 §2: key-mgmt 2.5→4, policy-approval 2.5→4, external-audit 1.5→3.5;
header now H5 76→80, lowest harness H6.
- INDEX row, README claim boundary, video-guide Q&A: 155 checks, H5=80, lowest H6=79.

## 4. Honest claim
|
||||
|
||||
Track A + Track C-MVP + Evidence Pack raise H4/H5/H6 from "PoC/demo (~3.0/5)" toward
|
||||
**early internal-production hardening (~3.8–4.0)**, with executable adversarial tests
|
||||
for every control. This is **not** full production readiness: serious production
|
||||
still needs Track B, Track C-Governance/Ops, true sandbox isolation, live IdP/WORM,
|
||||
and hosted telemetry — enumerated above and in `CASAN_PLAN_07_PRODUCTION_HARDENING.md`.
|
||||
Track A + Track C-MVP + Evidence Pack + H5 governance-hardening raise H4/H5/H6 from
|
||||
"PoC/demo (~3.0/5)" to **early internal-production hardening**, with executable
|
||||
adversarial tests for every control (155 checks, 0 fail — last full run 2026-07-04,
|
||||
KMS validated live via Vault). Fair maturity score (`00_SUBMISSION_PACKAGE/evidence/
|
||||
scoring-run-report.md`): per-harness **~80/100**, **H5 76→80** (approval-identity +
|
||||
KMS live + WORM), so the **lowest harness is now H6=79** (was H5=76) — CASAN **Level 4**,
|
||||
proven by attack. This is **not** full production readiness: serious production still
|
||||
needs live IdP (OIDC/JWT), a true WORM store (S3 Object Lock), KMS-by-default + HSM,
|
||||
true sandbox isolation, multilingual detection, and hosted telemetry — the [partial]/
