- SEC-08 pii-mask: fail-closed on missing rules / broken regex (no unmasked leak) - SEC-09: input-size cap + fail-closed reads (security-check/drift-detect/context-compress); non-UTF8 no longer crashes - SEC-19: control-plane store POSIX flock + atomic tmp+rename write - SEC-20: new toolchain-verify.sh (missing/PATH-shadowed/in-workspace binary -> refuse); wired into harness-preflight - SEC-21: model-call timeout 180->60s configurable + per-run call budget - SEC-11 realized by SEC-17 prod profile (no code) - 5 fail-able test suites wired into ci-harness-gate.sh; test-integrity manifest regenerated Verify: SEC+integrity gate 16/0, run-casan4 0-FAIL, adversarial 44/44, no regressions.

# security-check / drift-detect / context-compress ran superlinear passes (regex,

# SequenceMatcher) with no size cap (DoS) and crashed on missing / non-UTF8 input

# instead of returning a fail-closed verdict. This proves oversize input is blocked,

# Cap overridable via CASAN_MAX_INPUT_BYTES.
