Build Log
Added audit logging infrastructure — every admin mutation (28 total across Sanity CMS and Supabase) now records user ID, action, resource type/ID, and timestamp. Failed login attempts logged with email. Fire-and-forget design ensures audit failures never block user operations.
Security audit and hardening — Completed full security audit against OWASP standards. Implemented CSP headers, file upload validation, session idle timeouts, and serverless rate limiting. Documented remaining gaps (audit logging, resource-level auth) for follow-up.
Shipped 5 UX fixes to the Home Energy Load Calculator — sticky navigation, single-open accordions, collapsible schedule list, sticky column headers, and a branded PDF export that generates a professional energy profile report with logo, appliance breakdown, and actionable insights.
