[EPIC] M0 — Foundation & Developer Experience

[AKogut]

Tracking epic for the foundation milestone. Goal: a monorepo where pnpm i && docker compose up gives a working local platform, with shared type contracts and green CI.

Definition of done

• pnpm + Turborepo monorepo builds green in CI
• packages/contracts, packages/db, packages/core scaffolded
• docker compose up boots Postgres + MinIO + api + worker + web
• ADRs recorded for the load-bearing decisions (monorepo, OTel-native)
• Repo hygiene: README v1, CONTRIBUTING, templates, CODEOWNERS

Child issues

Linked below via the M0 milestone.

Architecture note

Monorepo is deliberate: the ingestion contract is shared across reporter → api → worker → web, and a single change must be atomic across all of them. See ADR-0001.

M0 is complete. Every child issue is closed and the definition of done is verified:

• ✅ pnpm + Turborepo monorepo builds green in CI — affected-only runs, node 20/22 matrix, required status checks on main
• ✅ contracts, db, core scaffolded — contracts and db fully implemented (zod contract with 21 tests, Prisma schema + migration + seed verified against Postgres 16)
• ✅ docker compose up boots Postgres + MinIO + api + worker + web with auto-migrate and seeded data visible
• ✅ ADRs 0001–0004 recorded with alternatives and consequences, plus docs/architecture.md
• ✅ Repo hygiene: README, CONTRIBUTING, CODEOWNERS, SECURITY, code of conduct, PR/issue templates

Beyond the original scope: changesets release pipeline (publish gated until #89), flakemetry.yml config-as-code, CLI scaffold with plugin-ready registry, and a hardened release workflow after the provenance incident.
