Decisions (ADRs)

Architecture Decision Records — one file per significant, hard-to-reverse choice. Each ADR captures the context, the decision, and the trade-offs so a future reader (human or agent) understands *why*, not just *what*. Numbered sequentially; superseded ADRs stay in place and link to their replacement.

📄️ADR-XXXX — Short title

Copy this file to start a new ADR. Number it sequentially and set the status.

📄️ADR-0001 — Gated CI/CD deploy pipeline for the backend

Backend deploys are controlled by GitHub Actions via Render deploy hooks — staging auto-deploys when checks pass, production runs the same checks behind a manual approval gate. render.yaml stays autoDeploy:false.

📄️ADR-0002 — Migrate the Postgres backend from Lightsail to ECS Fargate + RDS

Migrate the Postgres web backend off the single Lightsail box onto ECS Fargate + ALB + RDS PostgreSQL 16, run two environments (dev + prod, no staging) on a lean ~$118/mo profile, fix the iOS-ATS-blocking TLS cert with ACM, and decommission Lightsail after a rollback window.
