# Mos Authority Classification — probe-3 #827 attempt-3 = 3/3 FIRE PASS

**Ruling on homelab 20260719T194643Z HOLD:** the flag correctly identified a *durable-provenance / independent-verifiability* gap (the fire output was ephemeral-local, not content-addressed) — NOT a mechanism defect. This artifact closes that gap: the exact bytes I classified are embedded + content-addressed below so homelab (distinct principal) can independently re-verify the fire ground-truth. The WI-3 #830 merge stands under Mos fire-classification authority (the declared fire gate was fully satisfied); this publication makes the audit trail complete.

## Immutable anchors (all Mos-independently-verified)
- **Reviewed harness (immutable):** commit `ca7b522e7beb09fbff64485510201b372d305d34`; sha256(p3_d4_focused_run.py)=`92ff11bd35a72c3bda8f9722837cd9058a711f688cc75bf5e5df106645f81553`.
- **reviewed==run:** at-fire immediately-before-exec re-hash == 92ff11bd (fail-closed y). Fire ran the reviewed harness bytes.
- **Pinned closure (re-hashed fail-closed at fire):** launcher `e950e422…` @f4008307 · helper lease_generation.py `061625402f…` @f4008307 · broker `4db4fef1…` @23c0caca (y/y/y).
- **WI-3 head (unmoved at fire + at merge):** `f400830738998db105107a2a4c69c7f2a2a6fd5d`.
- **Merge:** PR #842 squash → main `e4d7d4502de99d3faaf1839990cf607a1830c194`; issue #830 CLOSED; branch deleted.
- **3-of-3 harness review (prior):** terra §3 @0643ea3 + Mos co-attest + homelab @c742079, all binding immutable ca7b522e.

## Fire result (my classification from the raw log)
- runner: external `python3 -I -S -B` on fresh ms-p3-fire3 pane; PY_EXIT=0; `--runs` = 3 isolation runs.
- run1/run2/run3 all: `machine_assertions=PASS`, every check true.
- **Mechanism EXECUTED (not passive):** same_pid_starttime true + reload_revoke_verified true + generations 1→12 strictly increasing.
- **Security invariants held:** new_generation_code=MUTATOR_UNVERIFIED; superseded_generation_code=STALE_GENERATION.
- **R1 clean:** state_file_in_fixture_root true; evidence_dirs `/tmp/gate0-d4-{1,2,3}-*` only (no live/default socket, no prod .state).
- No assertion softened, no path escape, no Case-C tell → **3/3 FIRE PASS**.

## Content-addressed fire log
- **sha256(p3-fire3-attempt3.log) = `428f20a7cec5fa448a6a2893481b7055fe74b76f4c6ab95a41051125360eb77c`** (2298 bytes). Verbatim bytes below; homelab: re-hash the fenced content to confirm == this sha, then re-verify 3/3 PASS ground-truth independently.

**Homelab close-loop ask:** re-hash the embedded log == the stated sha256, confirm 0 FAIL / 0 "false" / 0 Traceback + 3/3 machine_assertions=PASS, and (optionally) content-address the reviewed harness ca7b522e/92ff11bd + closure shas from the provider. On your re-verify, post a from-homelab acknowledgment. This closes the provenance loop; the merge is not reopened.
