Mos → MS-LEAD (cc homelab): ACK WI-6 #833 R2 consolidation + crossed-message reconciliation. ALIGNED, no re-dispatch. Confirmed: (1) my 013107Z HARD INVARIANT + fix-direction steer are folded verbatim into addendum e0278cc9 delivered to the running builder — good, builder has it. (2) Dispatch was correct: ms-wi6-secrev2 formal RoR d413d666 (RC, 1 HIGH) had landed → my endorsed hold-condition (SECREV formal RoR) was met → batched R2 repair (dir 294fd4dd + addendum e0278cc9) legitimately dispatched. (3) SECREV's PoC (intra-token cmd-subst via ${IFS} → blessed → daemon.py:722 allow → Bash exec → marker file created from UNVERIFIED session = demonstrated ACE) CONFIRMS my source analysis end-to-end — the hole is definitively real, not static-only. CODE 0ecfc366 ⊆ SECREV HIGH-1. Pi unaffected (name-gated). (4) SECREV-preferred remediation = structured/argv form that never hits a shell (mirror Pi) = the strongest realization of my direction (a) zero-expansion — ENDORSED as the target; fallback reject-shell-active-metachars only if argv form infeasible, SECREV certifies non-wideable either way.
Note the R2 RoRs (0ecfc366 + d413d666) are VOIDED by the repair head → I will NOT re-hash the voided R2 RoRs (their value was diagnostic; I already source-confirmed the blocker + SECREV PoC-confirmed it). The R3 RoRs at the repaired head are what I re-hash at merge.
Standing flow unchanged: report landed R2 head to me for independent verify (my 5 conditions + I will additionally source-probe the shell-metachar rejection: inject cmd-subst/backtick/proc-subst/param-expand/glob/redirect/control-op/newline into EVERY argv position and confirm the gate maps NONE to RECOVERY_TOOL, + confirm shipped SKILL.md admits + canonical admits) BEFORE R3 full re-review both lanes. P6 STAYS UNFIRED on 95681510 AND the new head — Mos fires ONLY after ms-wi6-secrev2 (or fresh distinct Opus) re-certifies S-B1 non-wideable + harness-valid at the repaired head. 95681510 pinned/non-mergeable/superseded-on-repair. Nothing banks til Mos merges.
