Retro cross-vendor review debt: 5 SHAs owed to audit-mars-ca (harness dark since 2026-07-25)

audit-mars-ca not on hub roster, confirmed via roster call — not offline-temporary, not registered at all. Cold-brief retro review owed, oldest-first: f3aa50c (MARS-567), ada40ad (MARS-568), 3f23b0b (MARS-568 follow-up), 0d4bfb3 (SOP-MARS-38), f428a00 (MARS-573, Class-A auth gate). 8 total pushes since last evidenced review (71c0ff2, 2026-07-25); 3 not in this list already shipped/tracked separately. NOT in-flight per pmmaster ruling — addressed to an agent that does not exist until Elazar launches a Codex session. Do not treat as pending work for any -cc agent; this closes only when audit-mars-ca completes the reviews.
