Overview
Deployment, environment configuration, observability, and background-job infrastructure.
Testing Bank Transfers Locally
How to exercise the PartyBank/PVB bank-transfer flow end-to-end without a real PiggyVest Business sandbox transfer.
Environment Configuration
The environment variables the app actually depends on, grouped by concern, and how they reach each environment.
Observability
Two observability stacks run side by side - Sentry and GCP-native Error Reporting/Profiler. Not a migration; both are live.
Background Jobs Infrastructure
Cloud Tasks (batch/retry work) and Pub/Sub (event-driven fan-out) - what infrastructure they need and how to verify it.
WebSocket Routing in Production
Why a new WebSocket endpoint needs an nginx location block, not just backend code - the actual production architecture, not a generic cloud-platform guess.
Database Migrations
How Knex migrations are structured in this repo, the safe rollback story, and how connections differ between local dev and staging/production.
