Coverage audit

Google Cloud Well-Architected Framework — 6 pillars, 174 recommendations, from the live documentation index, snapshot 2026-10-02 (0 days old).
Assessed 174 recommendations: 9 with diagram evidence, 165 cannot be determined.
Evidence sources: architecture diagram (services, boundaries, relationships).
Corpus read from a committed snapshot of the live documentation index (not re-fetched during this review). Re-read it with `archify-gcp wa corpus --refresh`. Statuses reflect what the diagram and spec show. Process, configuration and runtime evidence are not observable here, so those recommendations are 'Cannot Determine' rather than guessed.

Executive summary

This Google Cloud Well-Architected Framework review of Clinical notes pipeline (standard criticality) assessed the architecture diagram only. 9 of 174 framework recommendations have diagram evidence; the rest are Cannot Determine because process, configuration and runtime evidence is not in the diagram. It found 0 critical, 0 high, 1 medium and 0 low risk.

To confirm not drawn, so not counted as gaps

No private access or VPC Service Controls shown for managed data services SEC-2.1, SEC-7.10 — Reach Google APIs and managed data services through Private Google Access or Private Service Connect and put sensitive projects inside a VPC Service Controls perimeter.
No Cloud KMS shown for data at rest SEC-1.4 — Use Cloud KMS customer-managed keys (CMEK, Cloud HSM or EKM where required) with rotation and key-access audit logging for data at rest, and enforce TLS in transit.
No threat detection or posture management shown SEC-2.3, SEC-4.1 — Enable Security Command Center (Premium where justified), Cloud Audit Logs including Data Access for sensitive services, and Cloud IDS; route security logs to a central, access-restricted sink.
No backup or recovery capability shown REL-8.2, REL-8.1 — Protect data with Backup and DR Service or automated backups with point-in-time recovery, snapshots, object versioning and cross-region replicas, and test restores against your RPO/RTO.
No cost visibility shown COST-2.1, COST-2.6, COST-2.7 — Apply a consistent label scheme, export billing data to BigQuery and set Cloud Billing budgets with alert thresholds so spend maps to this workload and its owner.
Region choice is not tied to carbon intensity SUS-1.1, SUS-1.2 — Compare candidate regions by carbon-free energy percentage and grid carbon intensity (Google Cloud region picker) and use the Carbon Footprint report to track emissions.
