+MOS -> MS-LEAD (cc homelab): WI-6 #833 CONSOLIDATED RE-HASH + P6 FIRE = PASS. AUTHORITY RECORD.
+
+RE-HASH (independent, off-source, NOT relay-accepted):
+- Head UNMOVED @ 3277faadecbe243e700b2fdc8112b90f85a19d23 (full-40, fetched feat/833 branch, git rev-parse match).
+- main UNMOVED @ 07553ead337a70a9241f826d27571650262b289c; merge-base(head,main)=07553ead = clean descendant, no divergence.
+- CODE RoR sha256=2aa438ccc778c4535d49b3e90462bea27d7c591c7573da95daa955ebe298464c VERIFIED (reviewer ms-wi6-code terra, distinct from builder; APPROVED; D1-D4 + R-B1/R-FIREWALL/R-B2/R-sec4 all Y).
+- SECREV RoR sha256=47f1c95628a351b2da62e7fa1edd7220ad2ff64fff10e239c05f255fdd92d747 VERIFIED (reviewer ms-wi6-secrev3 FRESH DISTINCT Opus sec7; APPROVED; S-B1 NON-WIDEABLE=Y 0 bypasses no surviving PoC; gate-byte-unchanged-from-b6deed04=Y; S1-S7=Y; hatch-tripped=N; P6 harness-valid+held-unfired=Y).
+- 3 security files (mutator-gate.py, daemon.py, recover-context.py) byte-UNCHANGED b6deed04..3277faad (git diff exit 0) => my prior 20-vector shell-probe carries forward.
+- author != reviewer both lanes (terra + Opus sec7, both distinct from builder). N-a/N-b concur non-blocking, NOT folded (per 021014Z ruling).
+
+P6 FIRE (Mos-gated, authorized + executed by Mos):
+- Fresh DETACHED worktree /home/hermes/agent-work/mos-p6-fire-3277faad (!= builder), out-of-proc `python3 -I -S -B docs/compaction-refresh/probes/p6_constrained_recovery.py`.
+- PRE-PIN 3277faad PASS; RESULT "P6 constrained recovery probe PASS: 3 isolated shipped recovery-command runs" exit 0; POST-PIN 3277faad PASS (head UNMOVED pre+post); no leaked temp dirs.
+- §4 respected: probe launches shipped daemon on PRIVATE ephemeral sockets in mkdtemp (torn down), NO live broker/systemd/model-stream activation. hatch NOT tripped (recovery fully drivable out-of-proc).
+- Proven end-to-end: recovery mints FRESH challenge (!= normal-path), consume-before-promote, normal-receipt replay REFUSED (RECEIPT_MISMATCH), consumed-challenge re-promote REFUSED (INVALID_LEASE_TRANSITION), across pi/claude/pi.
+
+MERGE-GATE STATUS: admission=ADMISSIBLE. 6-check items 3(reviewed=head)/4(closes#833 will be in PR body)/5(author!=reviewer both lanes)=SATISFIED. BLOCKING items: (1) NO PR open yet + (2) NO Woodpecker CI at 3277faad. Mos opening the PR now (routine) to trigger pull_request CI -> Gate-2 terminal-green at 3277faad is the last gate before squash-merge. 3277faad STAYS PINNED. Will merge on CI-green re-verify (reviewed-SHA=CI-SHA=merge-SHA) + queue-guard. Nothing banked til merge.
