Phase 1A Execution

Phase 1A Execution: Application Skeleton and Module Boundaries

Status: Historical Phase 1A record at 706e854; current Phase 1 foundation status is in phase1_execution.md Phase 0A gate: Passed at 99% accuracy / 100% completeness on commit b9e7dee8b93a9639c56fe3348595bfa7e38f4d86
Scope: AC-38/39/51 and TR-25/26; no gameplay behavior

Approved boundary

Phase 1A sets up the Next.js application shell, explicit domain/application/infrastructure roots, and development commands. It does not implement the public landing page, lobby, identity, persistence, gameplay, or deployment. The project uses Next.js App Router with a modular monolith layout. Domain code remains free of Next.js, React, Supabase, OpenID client, and filesystem dependencies.

Red–Green record

Before creating the application shell, tests/architecture/phase1a-bootstrap.test.ts added five checks for the runtime dependencies, development/build/start/lint/type/test scripts, App Router files, DDD module roots, and the domain import boundary.

The first targeted run was red: all five checks failed because the skeleton, runtime packages, and scripts did not yet exist. The implementation added src/app/layout.tsx, src/app/page.tsx, empty context entry modules under src/domain, src/application, and src/infrastructure, plus Next.js and Biome configuration. The second targeted run passed all five checks.

Current verification

Check	Result	Boundary
npm test	5 files passed; 321 tests passed; 0 failed; 0 skipped	316 global mock-oracle and TR-19 tests plus 5 Phase 1A skeleton tests
npm run typecheck	Passed	Includes source, tests, and Next.js configuration
npm run lint	Passed	Biome checks src and Phase 1A architecture tests
npm run build	Passed	Local Next.js production build only; no Vercel Preview or deployment
AC-39 dependency attribution	Passed in full test suite	Exact runtime/dev dependency, lock, installed license, purpose, and upstream checks
Domain import boundary	Passed in full test suite	Static import scan over current src/domain files

The build confirms the shell compiles and prerenders /. It does not validate gameplay behavior or deployed artifacts. The Next.js build adjusted TypeScript's JSX, DOM library, and JSON-module settings; the resulting configuration is checked by npm run typecheck.

Implementation status

The App Router and three DDD context roots now exist. The home page is only a shell message. No game domain behavior, API routes, database schema, migrations, adapters, identity flow, or deployment scripts have been added. Keep the existing 45 active-AC oracles unchanged and run the relevant ones against real code as each later feature is implemented.

The next planned increment is 1B — Domain and application ports. Its tests must define the room, match, content, profile, clock, random source, deadline, quota, identity, and event boundaries before those interfaces are added.
