Four-artifact update per the coupling rule, plus the audit. 07-backup-architecture.md: §10.1 retitled CLOSED with the ruling and the D5 sentence; the FileBrowser network-share row flipped YES->NO, closed at the PLACEMENT rather than at the bind; the exposure chain annotated with the fifth surface (decommission-with-migrate guarded only its source) and the correction that the boundary is the deploy POST, not the dropdown; §7.3 retitled UNBLOCKED; register row collapsed; open question F answered. 00-capability-map.md: new §D row PROVEN-LIVE, with the un-exercised legs named — the deploy-POST and decommission refusals are unit-tested, not live-fired. OPEN-ITEMS.md: R-108 dispositioned; D5 given its OWN row as READY/UNBLOCKED (it had existed only inside other rows' prose — the R-123 thread-loss pattern); R-126 registered. ROADMAP.md: R-108 collapsed to a shipped one-liner; R-126 added. R-126 filed not fixed: a .fab bundle (plaintext secrets, optional password) can be exported ONTO a NAS. Split out of R-108 rather than folded in — it is an explicit customer-chosen export destination, not a browsing surface reaching a backup tree, so it was never part of D5's precondition. Live evidence: same-box before/after on demo-felhom through the real authenticated endpoint, the network-specific refusal on demo-hp, non-effect verified in the registry, and R-67's share-root bind diffed byte-identical across the deploy.
