This two-URL pattern is documented in `.env.example`. - **Nullable tenantId on User:** Super-admins are not scoped to a tenant — `tenantId` is nullable to support platform-level admin accounts without a separate SuperAdmin model. - **Per-tenant email uniqueness:** `@@unique([email, tenantId])` allows the same email to be used across different ISP tenants (realistic for the domain), while enforcing uniqueness within one tenant. - **Grace period fields on Tenant from day one:** `suspendedAt` and `gracePeriodEndsAt` were included at schema creation — adding them later would require a migration during production use. - **Vitest over Jest:** Vitest aligns with Vite's ecosystem (used by Next.js 15 internally), has faster cold starts, and supports ESM natively. ## Deviations from Plan ### Auto-fixed Issues **1. [Rule 3 - Blocking] Stopped conflicting isp-postgres container holding port 5432** - **Found during:** Task 1 (Docker Compose startup) - **Issue:** An existing `isp-postgres` container from a prior project was bound to 0.0.0.0:5432, preventing netforge_db from binding the same port - **Fix:** Ran `docker stop isp-postgres` to free the port, then re-ran `docker compose up -d` - **Verification:** `docker compose ps` shows netforge_db healthy with `0.0.0.0:5432->5432/tcp` - **Committed in:** 90bc583 (Task 1 commit) **2. [Rule 3 - Blocking] Force-recreated db container to establish host port binding** - **Found during:** Task 2 (prisma db push) - **Issue:** The initial `netforge_db` container was created before isp-postgres was stopped — it didn't get the host port binding. `5432/tcp` showed without host mapping. - **Fix:** Ran `docker compose up -d --force-recreate db` to recreate with proper port binding - **Verification:** `docker port netforge_db` shows `0.0.0.0:5432->5432/tcp`; `prisma db push` succeeded - **Committed in:** 1adeab2 (Task 2 commit) **3. [Rule 3 - Blocking] Worked around npm project name restriction** - **Found during:** Task 1 (Next.js initialization) - **Issue:** `npx create-next-app@latest .` fails because npm forbids capital letters in the project name ("NetForge") - **Fix:** Initialized in `netforge-temp/` subdirectory, then moved all files to root, updated package.json name to `netforge` - **Verification:** Project runs correctly; name is `netforge` in package.json - **Committed in:** 90bc583 (Task 1 commit) --- **Total deviations:** 3 auto-fixed (all Rule 3 - Blocking) **Impact on plan:** All fixes were environment-level blockers unrelated to plan scope. No architectural changes. No scope creep. ## Issues Encountered - `docker-compose.yml` included an obsolete `version: "3.9"` key that triggered a Docker Compose warning. Removed proactively to keep output clean. ## User Setup Required None — no external service configuration required. Everything runs locally via Docker Compose. ## Next Phase Readiness - Docker Compose dev environment is fully operational: `docker compose up -d` starts all three services - Prisma schema is synced to PostgreSQL — next plans can add models and run migrations immediately - `@/lib/prisma` is importable — all future server-side code can use the singleton client - Vitest is configured — TDD tasks in subsequent plans can use `npm test` immediately - No blockers for Phase 1 Plan 02 (authentication scaffold) --- *Phase: 01-foundation* *Completed: 2026-03-04*
