- CASAN_HARDENING_STATUS.md: canonical implemented/scaffold/planned record with per-control test mapping and test inventory (baseline 79 + 61 new = 140 checks). - README claim boundary: separate implemented+tested controls from planned; explicitly does NOT claim full production-readiness (Track B, C-Gov/Ops, true sandbox isolation, IdP/WORM still planned). - INDEX status table: Plan-07 Track A + C-MVP done, Plan-09 MVP done. - video guide: core demo battery counts unchanged (hardening lives in separate suites); added deep-dive commands + 3 Q&A rows + sandbox honesty note.

CASAN Production Hardening — Implementation Status
Live record of what has been implemented and tested from Plan-07 (Production Hardening) and Plan-09 (Evidence Pack), versus what is still planned. Honest by design: a control is only listed as done when it has an executable test that would fail if the control were removed.
Labels: [implemented+tested] · [scaffold+tested] (works, but a stronger production form is documented as TODO) · [planned] (not built).
1. What is implemented now
Phase 1 — Plan-07 Track A (low-risk hardening) — [implemented+tested]
| ID | Control | Where | Test |
|---|---|---|---|
| A1 | H4 semantic strict fail-closed (CASAN_SECURITY_STRICT=1): model unavailable ⇒ BLOCK, never silent SKIP; non-strict logs SEMANTIC_SKIPPED loudly |
security-check.sh |
phase1 A1 |
| A2 | H4 unicode/encoding normalization: NFKC + zero-width strip + homoglyph fold + base64/hex decode & rescan | security-check.sh, unicode-normalize.py, decode-suspicious.py |
phase1 A2 |
| A3 | H4 tool-output injection scan before output re-enters model context (mode off/warn/block; strict⇒block) | tool-output-scan.sh, casan-harness.sh |
phase1 A3 |
| A4 | H5 telemetry integrity: provider-usage + cost metrics bound to a signed manifest head (tamper ⇒ mismatch; re-forge ⇒ signature invalid) | telemetry-integrity.sh, sign-audit-head.sh |
phase1 A4 |
| A5 | H6 cost controls: absolute per-call cap + cumulative budget + cold-start protection, keeping median×mult spike | cost-spike-detect.sh |
phase1 A5 |
| A6 | Benign corpus (EN/VI/JA, 95 samples) + FP budget gate: FP ≤ 3%, adversarial block ≥ 95%, CRITICAL = 100% | benign-fp-report.sh, benign-corpus/, redteam-vectors.jsonl |
phase1 A6 |
Phase 2 — Plan-07 Track C-MVP (production minimum bar) — mixed
| ID | Control | Status | Where | Test |
|---|---|---|---|---|
| C1 | Tool authorization / action gating (ALLOW/WARN/REQUIRE_APPROVAL/BLOCK): sensitive-file writes, destructive/remote-exec commands, dep-install & network egress | [implemented+tested] | action-gate.sh |
phase2 C1 |
| C2 | Supply-chain gate: manifest diff, denylist + typosquat + dangerous lifecycle-script block, new-dep approval, dep-diff report | [implemented+tested] | supply-chain-gate.sh, supply-chain-scan.py |
phase2 C2 |
| C3 | Data-exfil guard: secret-to-cloud & artifact-leaks-env ⇒ BLOCK; PII-in-audit ⇒ mask | [implemented+tested] | data-exfil-guard.sh |
phase2 C3 |
| C6 | Runtime sandbox: static policy block (read ~/.ssh, net egress, fork bomb, write-outside-workspace, huge-file) + ulimit/timeout backstops | [scaffold+tested] | sandbox-run.sh |
phase2 C6 |
Phase 3 — Plan-09 Evidence Pack (MVP) — [implemented+tested]
| Control | Where | Test |
|---|---|---|
casan pack / casan verify-pack (mapped to evidence-pack.sh): standard 12-file pack, hash manifest, signed head, tamper-evident verify, certified-run gate (no false certification, no silent skip) |
evidence-pack.sh, evidence-pack-build.py, evidence-pack-verify.py |
phase3-evidence-pack |
2. Test inventory (all suites)
| Suite | Checks | Purpose |
|---|---|---|
run-casan4-harness-tests.sh |
35 | Baseline happy-path + Level-5 evidence (unchanged) |
adversarial-harness-tests.sh |
44 | Original adversarial battery (unchanged) |
phase1-track-a-tests.sh |
25 | New — Track A hardening |
phase2-track-c-tests.sh |
29 | New — Track C-MVP |
phase3-evidence-pack-tests.sh |
7 | New — Evidence Pack MVP |
| Total | 140 | Baseline 79 preserved; +61 new hardening checks |
Run order note: run-casan4-harness-tests.sh does rm -rf .specify/logs, so run it
first and never concurrently with the other suites.
3. What is NOT done (still planned — do not claim as production-ready)
| Area | Status | Plan ref |
|---|---|---|
| H4 multilingual detection (VI/JA injection block-patterns) | [planned] | Plan-07 B1 (V2) |
| Classifier-inject / split-injection resistance | [planned] | Plan-07 B2 (V5,V6) |
| HSM/rotation key management, TOCTOU re-verify | [planned] | Plan-07 B3 (V10,V11) |
| Model-digest pinning, sliding-window circuit breaker | [planned] | Plan-07 B4 (V15,V16) |
True runtime isolation (container --network=none --read-only --pids-limit, nsjail) |
[planned] — C6 is a static+ulimit scaffold only | Plan-07 C6 (V22) |
| Policy versioning + mandatory reviewer approval + rollback | [planned] | Plan-07 C4 (V20) |
| External append-only (WORM) audit | [planned] | Plan-07 C5 (V21) |
| Incident severity/kill-switch/runbook | [planned] | Plan-07 C7 (V23) |
| Telemetry signing under Vault KMS path | [partial] — local-key path done; KMS path signs unsigned | Plan-07 A4 follow-up |
| Live CVE/OSV scanning wired in | [partial] — availability detected; local denylist authoritative offline | Plan-07 C2 follow-up |
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.
