Stands up the LambdaMail monorepo per PLAN.md's F0 milestone: local dev scaffolding (.env.example, Makefile, .gitignore excluding PLAN.md/docs/ .superpowers/), the full initial Postgres schema as a golang-migrate migration, the complete Go domain layer for services/protocols (value objects, entities, domain events - zero external imports beyond github.com/google/uuid) with unit tests, health-checked service skeletons for auth/storage (TypeScript) and webmail (Next.js), a local docker-compose.yaml wiring all services together, a language-enforcement lint script, and a GitHub Actions CI workflow. Built via 11 sequential tasks under subagent-driven development, each with an independent implementer + reviewer cycle. Fixes applied during review: DomainName.IsPunycode() added to satisfy the promised interface; ioredis default-import typing under NodeNext; next.js bumped 15.0.3->15.5.21 to resolve high/critical CVEs; lang-lint.mjs corrected to not flag its own banned-terms list; web service healthcheck added so compose --wait actually waits on it; webmail Dockerfile's missing public/ directory: protocols go.mod version aligned with CI's Go 1.22 pin. Known follow-ups for later phases (not blocking F0): go-arch-lint isn't wired into CI yet; live docker compose up and migration apply have not been exercised in this dev environment (no Docker/psql available here) and will get their first real run in CI, which does have Docker.
