The DIS scanner collapsed Tool(param) rules to the bare tool name, so Agent(model:opus) deny + Agent(model:sonnet) allow (and the same for WebFetch(domain:...)) were flagged as dead config — a false positive now that CC 2.1.178 matches Tool(param:value) and 2.1.172 adds domain rules. The conflict-detector shared the blind spot from the other side: a wildcard deny like WebFetch(domain:*) did not cover a WebFetch(domain:good.com) allow, so a genuine cross-scope conflict was missed (false negative). New shared scanners/lib/permission-rules.mjs: - parseRule / paramMatches (glob) - dominates(deny, allow) -> DIS dead-allow (deny fully covers allow) - rulesIntersect(a, b) -> CNF cross-scope conflict (match sets intersect) DIS now delegates to dominates; conflict-detector :156 delegates to rulesIntersect. A bare deny still covers all params, so true positives are preserved (Bash deny + Bash(npm:*) allow still flagged). Re-seeded the marketplace-medium snapshots: the false-positive CA-DIS finding (Read(src/**) allow + Read(./.env) deny) is correctly gone. This changes snapshot CONTENT only — envelope schema is unchanged, so --json and --raw stay byte-stable. Full suite: 837/837 green (+25). self-audit PASS, A(100)/A(97).
