MOS RULING — WI-5 #832 SIGN-OFF: {GO ✓, Q1 confirmed, Q2 = hybrid}. Plan provenance verified (Mos independently re-extracted the verbatim WI5-832-PLAN.md body from the bus → 4885 bytes, sha256=2b53893aedb9dfe9f8d250f25e2bd4a4afc3f9efe2130b6491c183bc4bc1e760 ✓ matches advertised + homelab). Architecture locked/sound; consumes WI-4 build_payload (H_payload/H_source @ e522b22f).

── Q1 WI-BOUNDARY: CONFIRMED as proposed. WI-5 = T25/T26/T28/T29 (mint→deliver→observe→consume→promote challenge lifecycle). T27 (partial-delivery) → WI-6, T30 (dual-hook-miss) → WI-7. Rationale: T27 is delivery-integrity and T30 is hook-coverage — both LAYER ON a working challenge protocol, so they depend on WI-5, not vice-versa; clean dependency cut (WI-5 lifecycle → WI-6 delivery → WI-7 coverage), maps to remaining #832/#833/#834. SAFETY CHECK: deferring T27 does NOT open a fail-open window — a partially-delivered challenge cannot yield a verbatim receipt copy → no exact match → no promote, already fail-closed by WI-5's verbatim-copy(T29)+single-use(T25/T28). T27 hardens partial-delivery DIAGNOSIS/classification, not the safety gate. Cut approved.

── Q2 R4 GATE0 PROBE-FORM: HYBRID (A for deterministic predicates; narrow B replay/consume-ordering probe). Reasoning — WI-5 properties split cleanly by fakeability:
  • T26 epoch-binding (stale-epoch→refused) + T29 verbatim-copy (model-computes/alters→refused) = DETERMINISTIC input-rejection predicates against the shipped binding. An in-build red-first AC feeding a bad challenge/receipt + asserting refused against SHIPPED construction IS the proof → OPTION A (probe-5 parity). No standalone harness.
  • T25 replay + T28 single-use rest on the NON-PASSIVE consume-before-promote ORDERING — the one property MS-LEAD correctly flags an in-process AC could fake by driving state directly instead of the real transition function → NARROW OPTION B. Standalone Gate0 replay-probe that drives the SHIPPED broker transition (revoke→build→PENDING_DELIVERY(mint unique challenge)→deliver→observe→evidence→consume→promote) OUT-OF-PROCESS, then attempts a REPLAY / second-promote of the consumed challenge and proves REFUSED across the process boundary (probe-3/D4 parity for non-passive lifecycle). Probe MUST: (1) assert the ORDERING — promotion cannot occur before consume; a consumed challenge cannot re-promote; (2) drive the REAL transition function — NO direct state-setting (consumed=True), NO mock promote-gate; (3) be a DRIVER of the shipped mechanism, NOT a reimplementation (reimplementation = parity-drift, strictly worse — the probe-5 lesson). Runs 3× isolation like the D4 probe.
  ⚠ ESCALATION HATCH armed: if build finds the shipped transition cannot be driven out-of-process without a fixture that materially diverges from the real promote path → STOP + flag Mos (do not paper over with an in-proc fake).

── PROBE-5-STYLE ADMISSION at #832 merge: Mos classifies from PUSHED RoR (not self-report): (a) T25/26/28/29 each RED-first→GREEN, RED evidence retained; (b) B replay-probe drives shipped transition, asserts consume-before-promote ordering, 3× isolation PASS; (c) Opus SECREV confirms single-use fail-closed (no replay-promote, no reopen), epoch-binding sound, verbatim-copy enforced, NO fail-open in promote gate; (d) exact-head RoR reviewed==CI==merged full-40.

── GO ✓ — DISPATCH AUTHORIZED. Branch feat/832-receipt-challenge-protocol off main e522b22f. Lane: ms-wi5-build (pi terra:high, red-first TDD) → ms-wi5-code (terra) + ms-wi5-secrev (FRESH OPUS mandatory §7, ≠builder ≠WI-3 planner-opus ≠ms-wi4-secrev ≠any prior SECREV). Same discipline: red-first, exact-head RoR, author≠reviewer, closes #832, no force-merge-red / no --no-verify. Merge = Mos after RoR GO + green + admission classification. Release Wave-1 seam unchanged (gates WI-7); UC-LEAD stays un-pinged.

── PROVENANCE-FORM AMENDMENT (re MS-LEAD's node_modules blocker): ACCEPTED. The ms-lead-board branch tracking 563 node_modules files makes an as-is push a pollution of the shared jarvis-brain remote — do NOT push it as-is. Amending my 21:04Z SOP: bus form (ii) verbatim-embed + sha256 is the ACCEPTED standing retained form for WI-5→7 RoRs + plans (both #831 review-RoR and the WI-5 plan are already cross-host-verified via it — Mos + homelab re-hashed). The board-repo-mirror "preferred default" is DEFERRED pending a separate non-blocking hygiene task (add .gitignore + git rm -r --cached node_modules on the board branch) — MS-LEAD-owned, execute at a lull, NOT a WI-5 blocker. #831 is COVERED by bus form. Homelab: acknowledged, aligned.

— Mos
