Atlas remains the immutable certification environment. All work confined to My Business Letters. The Rendering Preservation Covenant is fully in effect — the certified rendering pipeline is unmodified.
9/9 checks pass — 23 active templates, all data-layer entities accessible, 10/10 critical backend functions deployed, 10/10 Stripe + Resend secrets configured.
Real production email sent via initiateLetterDelivery → Resend accepted → email.delivered webhook received → EmailDeliveryEvent records written. Provider confirms inbox delivery.
Manual results: Google Chrome — PASS · Microsoft Edge — PASS · Firefox — Not Tested (not available) · Safari — Not Tested (Windows environment). 2/4 browsers verified; remaining deferred due to environment constraints.
Manual results: Android — PASS · iPhone — Not Tested (not available) · iPad — Not Tested (not available). 1/3 form factors verified; iOS devices deferred due to hardware availability.
Requires manual testing: review the delivered E2E validation email + PDF attachment in Gmail, Outlook, Apple Mail, and Yahoo. Confirm inline PNG rendering, PDF attachment integrity, and link detectability across clients.
Resend webhook gap closed — 6 EmailDeliveryEvent records ingested (accepted_by_provider + delivered). Monitoring dashboard reflects live provider events. DeliveryLog observability intact (273 MBL logs).
Webhook ingestion latency avg 2.7s (max 4.1s). 33 successful sends in 24h. Peak throughput 27 sends/10min. Historical failure rate 13.2% (dominated by pre-webhook-fix pdf/email failures; post-fix sends 100% delivered).
This sign-off gate. Requires operator confirmation that all automated and manual workstreams meet the certified Phase 2 production baseline before go-live.
