Suggested labels: Merge Risk: 🟡 Moderate · up to The PR adds configurable execution of locally selected binaries and forward decoding, but malformed narration may be accepted, unsafe configuration-home values may allow unintended repository-controlled execution, and disabling the registration can falsely report that the pinned binary is active while an environment override remains selected.

Do not report the pinned binary after removing only the registration.
If GENTLE_PI_GENTLE_AI_DEV_BINARY is set, this command removes the registration file but the environment override remains selected. The current message says that the pinned binary is active while later resolution still executes the environment binary.
Resolve and report the override state after removal. Tell the user to unset GENTLE_PI_GENTLE_AI_DEV_BINARY when it remains active.
Proposed fix
if (argument === "off") {
const removed = unregisterGentleAiDevBinary();
- ctx.ui.notify(removed ? "Gentle AI dev binary registration removed; the pinned binary is active again." : "No dev binary registration to remove.", "info");

Reject empty and relative configuration homes. GENTLE_PI_CONFIG_HOME="" or "." makes dev-binary.json cwd-relative. A repository-controlled registration file can then activate an absolute executable override. This changes the override from a user-level opt-in to repository-controlled execution for processes with an empty or relative configuration-home value.

Validate the complete forecast narration sequence. The predicate accepts any collection of individually valid lines. It accepts a trailer without a horizon and a terminal horizon followed by the partial-only trailer. invoke then bypasses unexpected-stderr rejection for malformed output.
lib/native-review-cli.ts#L242-L245: parse the required line order and horizon-specific trailer rules.runtime/native-review-cli.mjs#L243-L245: keep the runtime parser equivalent.

Inherited-property lookup on CAPABILITIES_SCHEMA_IDENTITIES in lib/review-integration-v2.ts and runtime/review-integration-v2.mjs. Both files index the frozen identity map with the advertised schema string, so Object.prototype keys such as constructor resolve to a defined value and skip the unknown-identity guard. The shared root cause is the missing own-property check.
lib/review-integration-v2.ts#L816-L818: guard the lookup withObject.hasOwn(CAPABILITIES_SCHEMA_IDENTITIES, advertisedSchema)before readingidentity.runtime/review-integration-v2.mjs#L817-L819: regenerate this mirror from the corrected source so the same own-property guard applies.

Resolve the pinned fixture root from the module directory.
Line 31 resolves the dev-binary fixtures from import.meta.dirname. Line 33 resolves the pinned v2 fixtures from process.cwd(). If the test runner starts outside the repository root, v2Fixture throws ENOENT while fixture still works. Derive both roots from the module directory.
♻️ Proposed fix
-const v2FixtureRoot = join(process.cwd(), "contracts", "review-integration", "v2", "fixtures");
+const v2FixtureRoot = join(import.meta.dirname, "..", "contracts", "review-integration", "v2", "fixtures");📝 Committable suggestion
