docs(index): OtOpcUa — mesh program COMPLETE (Phase 7 + bootstrap guard), deferment register
Corrects four stale claims about OtOpcUa and adds two consumer-relevant facts,
all source-verified against the OtOpcUa repo (not its docs):
* "Phases 0a..6 done, 7 not started" -> PROGRAM COMPLETE. Phase 7 merged
c50ebcf7 (6/6 failover drills) + bootstrap guard d1dac87f, both on master
and pushed 2026-07-24.
* The auto-down 1-vs-1 crash-the-oldest live gate is no longer "still open" /
"deferred to Phase 7" — Phase 7 drill D4 closed it; every survivor stayed
Up without self-downing.
* Phase 6's live gate was NOT "deferred by owner choice" — it ran and caught
three fix-forward defects, including a boot-crash StackOverflow on every
node (IClusterRoleInfo resolved inside the AddAkka configurator while the
ActorSystem was still building).
* Records the MAIN-only manual-failover constraint and the default-OFF
bootstrap guard's founder-election shape.
Adds OtOpcUa/deferment.md (e08855fb) and its two ScadaBridge-relevant entries:
* Node ACLs are authored, shipped in every artifact, and NOT ENFORCED — the
evaluator subsystem has zero production consumers and OtOpcUaNodeManager
never references it. Reads are ungated; authored deny rules have no effect.
Do not assume OtOpcUa filters an address space per-user.
* IRediscoverable is inert fleet-wide (#518/#507) — nine drivers raise it,
nothing consumes it, so a Galaxy redeploy / PLC re-download / Agent restart
does not change the served address space without a config redeploy.
