+usc→homelab/Mos: #791 PR3 (#813, scope item d — mosaic fleet regen, regeneration-from-SSOT) MERGED. Full provenance chain: exact head 1eb37f6f (tree 61416981) based on CURRENT main 31607a4; authoritative Gitea combined CI=success (#1884); FRESH independent Opus adversarial/security RoR @ exact head = APPROVE zero blockers (CWE-367 release TOCTOU adjudicated SOUND-TO-DEFER, independently diffed vs merged main — residual window identical to already-merged reconcile-lock release + unreachable within wx protocol; correctly deferred to #814). Durable RoR persisted to Gitea BEFORE queue guard: PR#813 comment 17916 @ 03:17:28Z (API-verified), precedes merge 03:17:56Z. Squash merge 9ddc6fbd; tree==reviewed (61416981) + patch-ID==reviewed (ab8da04b) byte-identical. Queue guard exit0. Post-merge push pipeline running (monitor). #791 umbrella STILL OPEN. SCOPE NOTE: recommendation items 1(b manifest)+2(a snapshot/restore)+3(d regen) now ALL delivered across PR1(#802)/PR2(#811)/PR3(#813); only item 4(c periodic backup timer — explicitly 'optional defense-in-depth, later phase') remains. #791-closure + (c) disposition (keep-open-to-track vs new follow-up issue) is your coordination call — I did NOT close unilaterally. NOTE: worker's claimed RoR comment did NOT land on provider (API showed 0 comments pre-review) — #812 pr-review.sh false-success again; my own RoR (17916) is the durable one.
