Off is an explicit opt-out of OS-backed approval. The implementation must not reintroduce Windows Hello for merge, human reply, close, delete, or any other action. + +Off also must not claim that caller-provided `explicitInstruction` or `exactTextConfirmed` booleans are independently trusted user-consent provenance. In Off mode, authorization is derived from the routed mutation profile and workflow policy, while the receipt records that trusted authority was disabled by user configuration. `high-assurance` and `all` keep their existing OS-backed grant semantics. + +## Findings covered + +### GD-AUDIT-003 — caller-attested lifecycle intent in Off mode + +Remove the misleading trust elevation of raw request booleans when no trusted grant exists. Add an explicit Off-mode authorization path that treats trusted authority as disabled by user configuration rather than synthesizing trusted user intent. Raw request booleans must not be reported as trusted provenance. High-assurance/all behavior remains unchanged. + +Acceptance: +- Off-mode execution never calls the Authority host or Windows Hello. +- Raw `explicitInstruction:true` / `exactTextConfirmed:true` are not treated as independently verified provenance. +- Allowed actions remain bounded by the routed mutation mode/action policy and the normal broker invariants. +- High-assurance/all still require scoped trusted authority where configured. + +### GD-AUDIT-018 — required probe clean evidence can omit trigger files + +A required triggered probe may report `clean` only when its evidence proves coverage of every triggering file. Missing, empty, duplicate, or partial file evidence fails closed. Non-triggered/advisory probes retain their existing semantics. + +### GD-AUDIT-006 — classic branch-pattern parity + +Stop pretending the custom matcher is fully GitHub-compatible. Support only a deliberately proven subset of classic branch patterns with semantics matching GitHub's documented `File.fnmatch` behavior; fail closed when a pattern uses unsupported/ambiguous syntax. Add parity fixtures for escaped characters, bracket classes, dot-leading names, and unsupported constructs. + +### GD-AUDIT-022 — issue-body/repository-text prompt injection + +Destructive routing authority must come from trusted user text, not attributed repository content. Expand the attributed-untrusted-text stripper to cover issue bodies/descriptions and generic repository-text attribution, and add neutral/adversarial twins proving that an embedded `merge PR #...` instruction does not route to merge while a real user instruction still does. + +### GD-AUDIT-023 — named GraphQL mutation detector bypass + +The mutation-boundary scanner must detect both anonymous and named GraphQL mutation operations. Prefer a small operation-header parser over a mutation regex that only recognizes anonymous forms. Privileged files remain limited to the registered GraphQL mutation names; non-privileged production helpers must reject any GraphQL mutation. + +### GD-AUDIT-015 — unresolved-review-thread merge TOCTOU + +Keep GitHub-side conversation-resolution enforcement as the hard server-side backstop, and make merge execution require evidence that this enforcement is active and non-bypassable before the final merge mutation. Perform a final unresolved-thread recapture immediately before authority/broker execution and bind its capture to the same head/base snapshot. If conversation-resolution enforcement cannot be proven, fail closed instead of relying on the client-side snapshot alone. + +### GD-AUDIT-021 — behavioral-eval self-attested transcripts + +A plain JSON transcript plus matching canonical hash is internally consistent but not trusted execution provenance. Preserve unsigned/local behavioral scores for diagnosis, but they must be marked untrusted and must not be accepted as release/merge gating evidence. Add an attested provenance form whose signature binds the canonical transcript hash plus run identity; only attested runs may claim `trusted:true` for gating. + +## Testing strategy + +Use TDD for every finding: + +1. Add focused failing regressions for the exact exploit/false-green case. +2. Run focused tests and preserve RED evidence. +3. Implement the narrowest production change. +4. Run focused GREEN tests. +5. Run canonical `npm run check` plus Windows authority build/self-test and repository-security checks through CI. +6. Re-review the exact final diff for security/spec/correctness before PR completion. + +The Off-mode suite must contain a direct assertion that no Authority-host client/redeemer/Windows Hello path is invoked when `authorityMode=off`. + +## Non-goals + +- Do not remove or weaken `high-assurance` or `all` authority protection. +- Do not add a replacement interactive confirmation prompt in Off mode. +- Do not broaden mutation profiles or bypass expected-head, ownership, idempotency, stack, ship-gate, or publication checks. +- Do not turn behavioral-eval attestation into a network dependency for ordinary offline unit tests.

It does not mean “the agent can do anything.” Direct merge instruction, exact-text confirmation for human replies, expected-head checks, ownership checks, idempotency, workflow routing, ship gates, and all other mutation-policy rules remain mandatory. +In `off`, caller-controlled mutation JSON is not provenance for those user-confirmation facts. Request fields such as `explicitInstruction` and `exactTextConfirmed` are ignored as authorization claims. A governing workflow that actually observed the current user instruction or exact outgoing text must provide that fact out-of-band through the mutation execution context. The generic mutation-document entrypoint cannot mint it. This preserves zero-Hello operation without turning a self-attested request boolean into consent. + Dry-run planning never requires trusted authority. When the selected mode requires authority at `--execute`, the trusted grant must contain `scopeSha256`; a legacy resource-only signature is not enough. A **PR session** is an opt-in Hello grant, distinct from a branch lease. After Windows Hello, the approval UI may start a 5–60 minute session bound to one allowlisted repo, one PR, one head branch, and the approved merge base for merge. Later exact-scope `push_code` and `merge_pr` batches on that tuple skip Hello (`approvalMethod: pr_session`) but still receive one-time redeemable grants. A retargeted base requires Hello again. Branch leases remain `push_code` only for 1–10 minutes. Comments, human replies, close, and delete still need Hello. Mixed-action batches are not session-eligible.
