+# Gate0 Probe-3 (D4) Amendment — Adjudicator Ratification Record
+
+**Ratifies pin:** `9ac9ff873fad41a6e15763cc89cb94d0bc4a6b0cf9b6770561d1781b03f63276`
+(`GATE0-PROBE3-EXEC-AMENDMENT.md`, 7699 bytes, this branch).
+**Supersedes:** prior candidate pin `8fca5b7a` (never executed against; withdrawn on scope + durability grounds).
+
+## Re-scope-verify — PASSED
+Verified by **Mos (`web1:mos-claude`)**, acting as independent adjudicator (author ≠ verifier: MS-LEAD
+authored, Mos verified), 2026-07-18. SHA256 recomputed = pin (exact). Scope checks, all PASS:
+- §3 = Option A, D4-focused: harness spawns ONLY `p3_generation_broker.py`; minimal promotion-to-VERIFIED
+  is a FIXTURE PRECONDITION only (not P2 evidence-banking); D4 gen-bump revoke observation
+  (new→`MUTATOR_UNVERIFIED`, prior→`STALE_GENERATION`); **P5/P6 explicitly excluded + unauthorized**;
+  verbatim intrinsic-precondition boundary line present.
+- §1 binding model explicit; §2 charter provisions pinned unmutated; §4/§5 invariants intact.
+- No scope creep beyond the owner-authorized narrow class.
+
+## Authority binding
+- **Owner class-authorization (PRE-SHA):** Jason (owner) — "amend the charter" (option B), `#mos`
+  2026-07-18 17:28Z. Authorized the amendment class before these bytes existed.
+- **Independent-adjudicator byte-verification:** Mos scope-verified the exact bytes.
+- No single "Jason-signs-the-SHA" artifact exists or is required under this binding model.
+
+## Round-trip integrity (this branch/commit)
+All three files fetched back via the Gitea raw API and SHA-matched (each > 200B, no not-found sentinel):
+- `GATE0-PROBE3-EXEC-AMENDMENT.md` → `9ac9ff87…f63276` ✓
+- `charter-BUILD-BRIEF.md`         → `89fdbc27…71b` ✓
+- `charter-SPEC-RATIFICATION.md`   → `bac58319…67` ✓
+
+## Status: RATIFIED — probe-3 execution remains HELD
+Publication here closes the governance-infra gap (the charter provisions were previously local-only,
+not inspectable). Probe-3 execution stays HELD pending both: (1) homelab independent verification of
+these published bytes; (2) owner transparency window. On both clearing → ms-rev-826 builds + runs the
+§3 D4-focused harness (3× isolation, non-destructive) → PASS/FAIL to Mos → WI-3 (#830) chain per §6.
+
+*Note: the amendment file's own status line reads "DRAFT (revision 2)"; that internal text is
+superseded by THIS external ratification record (the pinned bytes are deliberately not edited, so the
+SHA stays stable). Ratification status lives here, not in the pinned artifact.*
