Re-ran all seven domain reviews at master f6eaa267 (reports rewritten in
place, each with a prior-finding status table): all 4 round-1 Criticals
verified closed; new top findings are the S7 connect-timeout OCE regression
(05/STAB-14), the ResilienceConfig operator-authorable brick (01/S-6), and
a batch of resilience-seam Mediums. 00-OVERALL.md carries the updated
maturity matrix + 12-item action list.
Adds R2-01..R2-12 design/implementation plans (one per action item, house
format + bite-sized TDD task breakdowns + co-located .tasks.json; 193 tasks,
~18-24 dev-days). STATUS.md updated: round-1 topology marked historical
(all merged+pushed), re-review findings table + plan pointers added.
