PR Summary

Low Risk
Infrastructure-only Blueprint addition with no runtime code changes; misconfigured env vars or migrations service behavior could affect production deploys but does not alter application logic in this diff.

Overview
Adds a new render.yaml Render Blueprint so Sim can be deployed from the dashboard with the same topology as docker-compose.prod.yml: shared Postgres (sim-db), Redis (sim-redis), web sim-app, web sim-realtime, worker sim-cron, and private sim-migrations running bun run db:migrate.

Env wiring uses groups for shared secrets (BETTER_AUTH_SECRET, INTERNAL_API_SECRET, ENCRYPTION_KEY, CRON_SECRET) and R2/S3 storage defaults; database and Redis URLs are linked via Blueprint references, with SOCKET_SERVER_URL / SIM_URL wired to internal hostport between services.

The file documents manual post-sync steps: enable pgvector, fill sync: false vars (public URLs, R2 credentials), align auth URLs across app and realtime, and validate whether sim-migrations as a private service matches desired one-shot migrate behavior vs a Render Job.

Greptile Summary

This PR adds a Render Blueprint for deploying the app, realtime service, cron worker, migrations, Postgres, and Redis. It also centralizes generated secrets and dashboard-supplied storage and URL configuration.

Provisions shared Postgres and Redis resources.
Defines app, realtime, cron, and migration services using the existing Dockerfiles.
Adds shared secret and R2 storage environment groups.
Requires several public URLs, credentials, and pgvector setup after the first Blueprint sync.

Confidence Score: 4/5

This PR should not merge until the internal realtime and app service references are converted into valid absolute HTTP URLs.

The Blueprint passes scheme-less hostport values directly to fetch and curl consumers, preventing realtime notifications and all cron-triggered endpoint requests from working on Render.

Files Needing Attention: render.yaml

Important Files Changed

Filename	Overview
render.yaml	Adds the complete Render deployment topology, but its internal service references provide bare host-and-port values where app and cron consumers require absolute HTTP URLs.

Scheme-less internal service URLs

When sim-app sends a realtime notification or sim-cron invokes a scheduled endpoint, Render supplies these hostport references as bare host:port values. The consumers interpolate them directly into fetch and curl URLs without adding a scheme, causing realtime notifications and scheduled processing to fail URL parsing.

+      # sim-app only, but kept here so it's generated once, in one place.
+      # Cannot be changed later without losing stored credentials.
+      - key: ENCRYPTION_KEY
+        generateValue: true


Invalid auto-generated encryption key

High Severity

ENCRYPTION_KEY uses generateValue: true, but Render generates a base64 256-bit secret (~44 chars), not the 64-character hex string the app requires. Credential encrypt/decrypt will throw at runtime once anything tries to use ENCRYPTION_KEY.

+          name: sim-realtime
+          property: hostport


Internal URLs missing HTTP scheme

High Severity

SOCKET_SERVER_URL and SIM_URL are wired from hostport, which is bare host:port with no scheme. Compose and Helm use full http://… URLs; server fetch and cron curl need a scheme, so realtime notifications and all scheduled jobs will fail to reach their targets.

Render's Blueprint schema has no service-level envVarGroups field — groups are attached per-entry inside a service's envVars list via fromGroup, not with a separate top-level key on the service. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Render removed the legacy Starter/Standard/Pro Postgres plan names for new databases in favor of Basic/Pro/Accelerated tiers named by RAM. basic-4gb is the closest match to the old 'standard' size. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

+    # replaced Starter/Standard/Pro with Basic/Pro/Accelerated tiers named by
+    # RAM. basic-4gb is the closest new-tier match to the old 'standard' size;
+    # resize up (pro-*) or down (basic-1gb/basic-256mb) as load requires.
+    plan: basic-4gb


Wrong Postgres plan for Standard

Medium Severity

The Blueprint replaces legacy standard with basic-4gb, and the comment calls that the closest match. Legacy Standard is 1 GB RAM; basic-1gb is the RAM- and price-aligned successor, while basic-4gb matches legacy Pro (4 GB). One-click deploys get roughly 4× the intended DB cost and capacity relative to the old plan this change claims to replace.
