 - ARCHITECTURE §3 topology diagram listed Crossplane, Flux, Harbor, grafana-stack INSIDE the Catalyst control-plane block. But §11 and PLATFORM-TECH-STACK §3 both classify these as per-host-cluster infrastructure (not Catalyst control plane). Topology diagram corrected; per-host-cluster infra now shown as a separate line referencing PLATFORM-TECH-STACK §3 for the full list. Also added the previously-missing `provisioning` row.
 - JetStream Account scoping was contradictory: ARCHITECTURE §5 said "Per-Org account: ws.{org}-{env_type}.>" (ambiguous), NAMING-CONVENTION §11.2 said "One JetStream Account scoped to ws.{org}-{env_type}.>" (per-Env), GLOSSARY+SECURITY+PLATFORM-TECH-STACK said per-Org. Reconciled to: one Account per Organization, subjects within use prefix `ws.{org}-{env_type}.>` for per-Environment partitioning. Fixed in ARCHITECTURE §5 and NAMING-CONVENTION §11.2.

+- SECURITY.md: clean. Multi-region OpenBao (§5), Keycloak topology (§6), rotation policy (§7) all consistent with each other and with NAMING / ARCHITECTURE / GLOSSARY.
+- platform/kserve: banner correctly identifies as Application Blueprint under bp-cortex. The example `namespace: ai-hub` is illustrative (AI Hub is a customer-chosen Application name); not a strict contradiction with the agreed naming convention.
