Summary

• Task 1: built a DB-only Polymarket-style web UI (Fastify + Prisma API, Next.js 14 web) on branch claude/jun-19-verex; both builds pass.
• Task 2 prep: added deploy scaffolding (env templates + DRAFT scripts/deploy.sh for 2 Cloud Run services + Cloud SQL), held for review as a PR.
• Added local dev tooling (scripts/dev-local.sh) and educational scripts/README.md.
• Fixed API 500 (DATABASE_URL not found) via import "dotenv/config", and hardened deploy.sh (multi-stage Dockerfiles, runtime API_URL, 365 fewer packages).
• Deploy succeeded end-to-end after 3 cloud fixes (Cloud SQL edition, ADC quota-project, missing @types/node); site live on *.run.app, custom domain pending.
• Post-merge fix: gitignored auto-generated next-env.d.ts that blocked git pull on main.

Verex Task 1: basic prediction-market web UI (DB-only)

• Implemented the Polymarket-style web UI per docs/tasks/jun-19-verex-design.md on branch claude/jun-19-verex; DB-only — no smart-contract integration yet (per spec).
• API (packages/api, Fastify + Prisma): switched from contract-backed to Postgres-backed — added prisma/schema.prisma (Market + Outcome, categorical = N outcomes), a Prisma client (src/db.ts), DB-backed endpoints GET /markets (?category=), GET /markets/:slug, GET /categories, plus CORS; dropped the @verex/sdk dependency for v1.
• Seed (prisma/seed.ts): 10 categorical markets across Politics, Sports, Crypto, Economy, Geopolitics with static seeded prices (idempotent re-seed). Web (packages/web, Next.js 14): homepage (category tabs, featured market, market grid) + market detail page (/market/[slug]) with outcome probability bars, reading the API via NEXT_PUBLIC_API_URL; plain CSS (no Tailwind), pages force-dynamic.
• Verified: pnpm --filter @verex/api build and pnpm --filter @verex/web build both pass; live UI not run here (needs the DB, deferred to deploy).

Verex Task 2 prep: deploy scaffolding

• Added env templates (scripts/deploy.env.example, packages/api/.env.example, packages/web/.env.example + NEXT_PUBLIC_API_URL) and a DRAFT scripts/deploy.sh (two Cloud Run services + Cloud SQL, modeled on rabbit); scripts/deploy.env (project ID + REGION=asia-northeast3) is gitignored.
• Live deploy held for review — it creates billable resources and needs the DNS record + domain verification + migrate/seed against Cloud SQL. Opened as a PR for review (not merged); the live GCP deploy will be done together.

Local dev tooling + learning docs

• Added scripts/dev-local.sh — one command for local setup (Docker Postgres → prisma db push → seed 10 markets → write local .env files).
• Added a "Run the web UI locally / Deploy" section in the README and an educational scripts/README.md explaining every Docker / Postgres / GCP command.

Bug fix: API 500 — Environment variable not found: DATABASE_URL

• Symptom: pnpm --filter @verex/api dev returned 500 on every request with PrismaClientInitializationError: Environment variable not found: DATABASE_URL.
• Root cause: the Fastify API (tsx watch) does not auto-load .env at runtime (only the Prisma CLI does), so even though dev-local.sh writes packages/api/.env, the server never read it and DATABASE_URL was undefined (Next.js auto-loads .env.local; bare Fastify doesn't).
• Fix: added import "dotenv/config"; as the first line of packages/api/src/index.ts and added dotenv to API deps. To apply: pnpm install, then restart the API; Postgres must be running (dev-local.sh), else the next error is "Can't reach database server at localhost:5432". Uncommitted on claude/jun-19-verex — to fold into PR #7.

Deploy hardening — made deploy.sh actually runnable

• Reviewed deploy.sh and fixed blockers that would fail / leave half-built billable resources.
• Web build blocker: dropped @verex/sdk (workspace:*) plus unused wagmi/viem from packages/web (none imported in v1) → standalone build works, 365 fewer packages. Container builds: added multi-stage Dockerfiles for packages/api and packages/web (copy-only-artifacts) + a .dockerignore each (no .env leaks); next.config.js → output: "standalone", added public/.gitkeep.
• API URL chicken-and-egg: web now reads a runtime API_URL (server-side fetch) instead of build-time NEXT_PUBLIC_API_URL, set after the API deploys (no rebuild). deploy.sh rewrite: auto-generates the DB password → Secret Manager (reused on re-runs, never printed); runs prisma db push + seed through the Cloud SQL Auth Proxy; deploys API → web (with runtime API_URL) → prints the domain-mapping step.
• Verified: both packages build; web produces .next/standalone (what the Dockerfile expects). The Cloud Build / proxy / gcloud flow is reviewed, not run — to be exercised on the first *.run.app deploy (before the domain); needs gcloud auth application-default login. Still uncommitted on claude/jun-19-verex — to fold into PR #7.

Deploy prerequisites — quick check (before the first run)

deploy.sh is now runnable; before the first run, confirm:

First run is a fix-as-you-go on the *.run.app URL; do not map verex.jaylabs.xyz until that URL works. Run it watched, not unattended.

Deploy run #1 — fixes as they surfaced

• Cloud SQL edition error — db-f1-micro was rejected: the instance defaulted to the Enterprise Plus edition, which only allows pricey db-perf-optimized-* tiers. Fix: added --edition=ENTERPRISE to gcloud sql instances create (Enterprise allows the cheap shared-core db-f1-micro, ~$8–10/mo). Failure was at instance-create → nothing billable created; script is idempotent → just re-run.
• ADC quota-project warning — "active project does not match the quota project in your Application Default Credentials." Harmless, but can bite the Cloud SQL Auth Proxy step later. Fix: gcloud auth application-default set-quota-project <PROJECT_ID>. Note: ADC is a local credential file (~/.config/gcloud/application_default_credentials.json), not a Console setting — changed via gcloud, not the web Console.
• API container build failed at npx tsc: Cannot find type definition file for 'node' / Cannot find name 'process'. Cause: @types/node was missing from packages/api — it built locally (pnpm hoists @types/node from the workspace) but the standalone Docker npm install didn't have it. Fix: added @types/node to packages/api devDeps. (Lesson: per-package Dockerfiles need each package to declare all its own types — no hoisting.) The cloud-sql-proxy binary is downloaded to the repo root by deploy.sh → added to .gitignore.

✅ Deploy succeeded

• After the three fixes, ./deploy.sh ran end-to-end: Cloud SQL (verex-db, Enterprise/db-f1-micro) → Secret Manager (DATABASE_URL) → migrate + seed (10 markets via the proxy) → verex-api and verex-web deployed to Cloud Run; site reachable at the *.run.app URL.
• Pending — go-live: map verex.jaylabs.xyz (domain mapping + DNS record at the registrar + SSL) — deliberately the last step, after the *.run.app URL is confirmed working.

Post-merge fix — next-env.d.ts blocked git pull

• Symptom: after merging PR #7, git pull on main aborted: "untracked working tree files would be overwritten by merge: packages/web/next-env.d.ts."
• Cause: next-env.d.ts is auto-generated by Next.js (every build) and shouldn't be committed, but git add -A had grabbed it because verex's .gitignore didn't list it; the locally-generated untracked copy then collided with the committed one on pull.
• Fix: removed the local copy → pulled to fast-forward main; then gitignored next-env.d.ts + *.tsbuildinfo and git rm --cached-ed it (untracked, file kept on disk). Committed directly to main (trivial), per jay.
