Add the 7 per-domain design+implementation plans (archreview/plans/) with
an index, produced from the 2026-07-08 architecture review.
Fix two confirmed doc drifts the review flagged (theme #5):
- CLAUDE.md KNOWN LIMITATION 2: the continuous-historization historized-ref
feed IS wired (AddressSpaceApplier.FeedHistorizedRefs -> UpdateHistorizedRefs
-> recorder); rewrite to reflect that value-capture is code-complete and only
the live end-to-end + restart-convergence verification remains.
- CLAUDE.md ScriptAnalysis gating: endpoints use Roles=Administrator,Designer
via RequireAuthorization, not the FleetAdmin policy.
