- SEC-12: drift-detect adds semantic invariants — negation-flip detection (a dropped "not" now FAILS despite high char-similarity) + env must-keep patterns. - SEC-29 (X-05): governance-check audit write fails CLOSED — an unwritable audit log denies the action and empties the output (no unaudited output). - SEC-30 (X-06): approval-verify records a one-time-use nonce (sha of token/sig) and rejects replays (enforced mode / when a nonce ledger is set); dev unchanged. - SEC-15 (low): typosquat distance<=2 with the levenshtein length-sentinel bug fixed (no false positives); tool-exec fails closed with no timeout backend in enforced mode; validate-tool-input now validates nested objects/arrays recursively. Verify: new SEC suites all green via gate, run-casan4 0-FAIL, adversarial 44/44, track-c 29/0, h5-approval 12/0, no regressions. Plan-16 P2 remaining: infra-gated only (SEC-14/22/23/24/25/26).

# CASAN Plan-16 SEC-12 — drift-detect semantic invariants (beyond char-similarity).
|
|
#
|
|
# Char-similarity alone misses a SEMANTIC inversion: dropping a negation
|
|
# ("must NOT deploy" -> "must deploy") keeps similarity ~0.97 but flips the meaning,
|
|
# and previously passed. Now a candidate that removes negations present in the
|
|
# golden, or that drops a must-keep invariant, FAILS. Proves the flip is caught and
|
|
# identical/benign content still passes.
|
|
#
|
|
# Deterministic; hermetic.
