-# Implementation Plan: First-Start Create Admin Modal 1.06 — Bootstrap Race Fix
-
-## 0. Status
-
-**[ALREADY_IMPLEMENTED]**
-
-The race described in Job 847 is already fixed in the current codebase. Two
-near-simultaneous `POST /api/v1/setup/create-admin` requests can no longer
-both succeed: exactly one returns HTTP 201 and the other returns HTTP 409
-`SYSTEM_INITIALIZED`. No new code or test work is required.
-
-## 1. Architectural Reconnaissance
-
-- **Codebase style & conventions:** TypeScript, NestJS 10+ (modular, DI,
-  controllers + services), class-based services, TypeORM with the
-  `DataSource.transaction` API, `zod` DTOs guarded by
-  `ZodValidationPipe`, a project-wide `ApiError` / `ERROR_CODES` enum,
-  and Argon2id password hashing.
-- **Data Layer:** SQLite (in-memory for tests, file-based for runtime),
-  TypeORM entities; the bootstrap flow wraps all admin creation inside
-  a single `DataSource.transaction` so the `adminCount > 0` guard and
-  the user insert commit atomically.
-- **Test Framework & Structure:** Jest. Tests live exclusively under
-  `/repo/tests/` (separated into `tests/backend/` and `tests/frontend/`),
-  never alongside source. Backed by a `csrfClient` helper in
-  `tests/backend/csrf-client.ts` and an `initDb(app)` helper that uses
-  SQL migrations to provision the in-memory database. Tests are
-  runnable from the repo root via the standard `npm test` pipeline.
-- **Required Tools & Dependencies:** None beyond the existing stack
-  (NestJS, TypeORM, better-sqlite3, argon2, zod, Jest, Supertest,
-  uuid). No new package, system tool, or `setup.sh` change is needed.
-
-## 2. Impacted Files
-
-The implementation already exists in these files; no further edits are
-required:
-
-- **To Modify:** None.
-- **To Create:** None.
-- **Existing files that already contain the fix (read-only references):**
-  - `backend/src/modules/setup/setup.service.ts:23,39-97,111-130` —
-    `SetupService.createAdmin` runs every bootstrap attempt through
-    `runBootstrap()`, which serializes callers on a per-process promise
-    chain (`#bootstrapChain`) so two concurrent transactions cannot
-    both observe an empty `user` table.
-  - `backend/src/modules/setup/setup.service.ts:60-95` — Each
-    serialized call executes inside `dataSource.transaction(...)`,
-    performs the `adminCount > 0` check first, throws
-    `ApiError(SYSTEM_INITIALIZED, 409)` on the loser, then performs the
-    `username` uniqueness check, Argon2id hash, and `UserEntity`
-    insert on the winner.
-  - `backend/src/modules/setup/setup.module.ts` — Wires
-    `RegistrationRateLimitService`, `JwtService`, `ConfigService`,
-    `DataSource`, and the user/refresh-token repositories into
-    `SetupService`.
-  - `backend/src/common/errors/api-error.ts`,
-    `backend/src/common/errors/error-codes.ts` — Provide `SYSTEM_INITIALIZED`
-    and the 409 mapping consumed by `GlobalExceptionFilter`.
-  - `tests/backend/setup-create-admin.spec.ts:121-149` — Existing
-    regression test `"only one of two concurrent first-admin requests
-    succeeds; the other receives a controlled conflict"` already
-    reproduces the race described in the Job and asserts
-    `[201, 409]`, the loser's `SYSTEM_INITIALIZED` code, exactly one
-    admin row, and exactly one `refresh_token` row.
-
-## 3. Proposed Changes
-
-No changes. The Job's expected behaviour is already enforced by two
-cooperating layers:
-
-1. **Database / Schema Migration:** None. The existing `user.role`
-   index plus the in-transaction `adminCount` check are sufficient.
-2. **Backend Logic & APIs:** `SetupService.createAdmin` already wraps
-   the whole bootstrap pipeline in `runBootstrap()` which serializes
-   callers on a single process-local promise chain, and each task
-   itself runs inside a `DataSource.transaction` whose first action is
-   the `adminCount > 0` guard. The controller path
-   `POST /api/v1/setup/create-admin` already maps the
-   `SYSTEM_INITIALIZED` `ApiError` to HTTP 409 via
-   `GlobalExceptionFilter`.
-3. **Frontend UI Integration:** No change needed. The frontend service
-   `frontend/src/app/features/setup/setup-create-admin.service.ts`
-   already switches on `CreateAdminResult` and surfaces 409 as the
-   "system already initialized" inline error with a Retry affordance.
-
-## 4. Test Strategy
-
-The required regression test already exists and is the test that proves
-the fix. No additional tests are planned because:
-
-- The failing scenario in the Job (two concurrent `adminAlpha` /
-  `adminBeta` requests both returning 201 with admin rows + two
-  `refresh_token` rows) is exactly the scenario covered by
-  `tests/backend/setup-create-admin.spec.ts:121-149`.
-- Adding a second concurrent-race test would duplicate coverage without
-  exercising new behavior, violating the "minimal, highly-focused tests"
-  constraint.
-
-If a future run of `npm test` ever fails this spec, the implementer
-should investigate `SetupService.runBootstrap` and the transactional
-`adminCount` guard (not add tests).
-
-### Verification commands (for the implementer only — not for execution here)
-
-- `npm test -- tests/backend/setup-create-admin.spec.ts` — confirms
-  201/409 outcome, single admin row, single `refresh_token` row.
-- `npm test` — full Jest run from the repo root.

+# Implementation Plan: Job 848 — First-Start Create Admin Modal 1.07
+
+## Status
+
+**[ALREADY_IMPLEMENTED]**
+
+The First-Start Create Admin Modal feature is fully implemented end-to-end in
+this repository. The user-facing symptom reported in the job ("HIPCTF heading +
+'Frontend not built.' paragraph, no bootstrap dialog, no form controls, no
+submit button") is produced by the SPA fallback in
+`backend/src/frontend/spa.controller.ts:27` whenever
+`frontend/dist/browser/index.html` does not exist on disk at the moment
+the request is served.
+
+That `dist/browser/index.html` is now present (rebuilt during the current
+session), so navigating to `http://localhost:3000/` will serve the Angular
+SPA, which redirects to `/bootstrap` and renders the create-admin modal.
+
+No source code changes, no schema changes, and no new tests are required.
+
+## 1. Architectural Reconnaissance
+
+- **Codebase style & conventions:**
+  - Monorepo with npm workspaces (`backend/`, `frontend/`).
+  - Backend: NestJS controllers + services, TypeORM repositories,
+    `@nestjs/config`, argon2 for password hashing, class-validator /
+    `ZodValidationPipe` for input, `ApiError` + `GlobalExceptionFilter`
+    for the uniform `{ code, message }` error envelope.
+  - Frontend: Angular 17+ standalone components, `ChangeDetectionStrategy.OnPush`,
+    Angular Signals, reactive forms (`ReactiveFormsModule`), HTTP via
+    `HttpClient` with `withCredentials: true`, separate
+    `BootstrapService` (initialised flag) and `AuthService` (session token).
+  - Persistence: SQLite via TypeORM, file path comes from
+    `process.env.DATABASE_PATH` (default `/data/hipctf/hipctf.db`),
+    `FRONTEND_DIST` env var names the built SPA directory.
+- **Data Layer:** SQLite (TypeORM). No schema change is needed.
+- **Test Framework & Structure:**
+  - Jest with two projects (`backend`, `frontend`) configured in
+    `tests/jest.config.js`.
+  - Backend tests use `ts-jest` against an in-memory SQLite DB
+    (`process.env.DATABASE_PATH = ':memory:'`) via
+    `tests/backend/db-helper.ts`.
+  - Frontend tests use `jest-environment-jsdom` with
+    `tests/frontend/jest.setup.ts` providing Angular `TestBed` +
+    `provideHttpClientTesting`.
+  - All tests live under `tests/` and run via a single root command:
+    `npm test` (alias for `jest --config tests/jest.config.js`).
+- **Required Tools & Dependencies:** No new tools. Existing `npm run build`
+  in `setup.sh` rebuilds `frontend/dist/browser/index.html`, which is the
+  actual fix for the symptom. No new packages are required.
+
+## 2. Impacted Files
+
+- **To Modify:** None.
+- **To Create:** None.
+
+### Where the feature already lives (for reference / verification)
+
+Backend:
+- `backend/src/modules/setup/setup.module.ts`
+- `backend/src/modules/setup/setup.controller.ts` — `POST /api/v1/setup/create-admin`.
+- `backend/src/modules/setup/setup.service.ts:39-97` — `createAdmin()` inside a
+  TypeORM transaction with serialized bootstrap via `runBootstrap()`
+  (lines 99-130) — guarantees that two concurrent callers cannot both
+  observe an empty admin table; the loser gets
+  `409 SYSTEM_INITIALIZED`.
+- `backend/src/modules/setup/dto/create-admin.dto.ts`
+- `backend/src/common/errors/error-codes.ts` — `SYSTEM_INITIALIZED`,
+  `USERNAME_TAKEN`, `WEAK_PASSWORD`, `VALIDATION_FAILED`, `RATE_LIMITED`.
+- `backend/src/frontend/spa.controller.ts:11-28` — SPA fallback that emits
+  the placeholder HTML **only** when no built `index.html` is found.
+
+Frontend:
+- `frontend/src/app/features/setup/setup-create-admin.component.ts` — the
+  modal component (`data-testid="setup-submit"`, `setup-retry`, etc.).
+- `frontend/src/app/features/setup/setup-create-admin.component.html`
+- `frontend/src/app/features/setup/setup-create-admin.component.css`
+- `frontend/src/app/features/setup/setup-create-admin.service.ts` —
+  `POST /api/v1/setup/create-admin` with CSRF preflight + error mapping.
+- `frontend/src/app/features/setup/setup-create-admin.validators.ts` —
+  `passwordMatchValidator`.
+- `frontend/src/app/features/setup/setup-create-admin.field-errors.ts` —
+  pure helpers `usernameError`, `passwordError`, `confirmError`.
+- `frontend/src/app/core/services/bootstrap.service.ts` — exposes
+  `initialized()`, `markInitialized()`, and `passwordPolicy()`.
+- `frontend/src/app/core/services/auth.service.ts` — `setSession()` used
+  on success.
+- `frontend/src/app/app.routes.ts` — `/bootstrap` route, guarded by
+  `authGuard` which redirects to `/bootstrap` while `initialized() === false`.
+
+Existing tests that already cover this Job:
+- `tests/backend/setup-create-admin.spec.ts`
+- `tests/backend/bootstrap.integration.spec.ts`
+- `tests/backend/registration-rate-limit.spec.ts`
+- `tests/backend/api-error.spec.ts`
+- `tests/frontend/setup-create-admin.spec.ts`
+- `tests/frontend/guard-bootstrap-race.spec.ts`
+- `tests/frontend/auth-restore.spec.ts`
+
+## 3. Proposed Changes
+
+No code changes. The only operational fix is to keep
+`frontend/dist/browser/index.html` in place.
+
+If a fresh container runs without it, `setup.sh` already invokes
+`npm --workspace frontend run build` (line 11) which produces the Angular
+bundle under `frontend/dist/browser/index.html`. The
+`SpaFallbackMiddleware` looks for the file in both
+`frontend/dist/index.html` and `frontend/dist/browser/index.html`, so the
+standard build output is resolved without any extra wiring.
+
+## 4. Test Strategy
+
+No new tests. The relevant behaviour is already covered:
+
+- **Backend:** `tests/backend/setup-create-admin.spec.ts` exercises
+  `POST /api/v1/setup/create-admin` happy path + each documented error
+  (`SYSTEM_INITIALIZED`, `USERNAME_TAKEN`, `WEAK_PASSWORD`,
+  `VALIDATION_FAILED`, `RATE_LIMITED`).
+- **Backend concurrency:** the `runBootstrap()` chain in
+  `SetupService` is what serializes concurrent first-admin requests;
+  `tests/backend/bootstrap.integration.spec.ts` exercises the bootstrap
+  endpoint end-to-end.
+- **Frontend:** `tests/frontend/setup-create-admin.spec.ts` covers the
+  modal's reactive form, server-error states, retry button, and the
+  post-success navigation. `tests/frontend/guard-bootstrap-race.spec.ts`
+  covers the `authGuard` redirect race with `BootstrapService`.
+
+Run the existing suite from the repo root with:
+
+```
+npm test
+```
+
+## 5. Why this is reported as "not built"
+
+`SpaFallbackMiddleware` (`backend/src/frontend/spa.controller.ts:27`)
+sends:
+
+```
+<!doctype html><html><body><h1>HIPCTF</h1><p>Frontend not built.</p></body></html>
+```
+
+when neither `frontend/dist/index.html` nor `frontend/dist/browser/index.html`
+exists. The Angular CLI's `application` builder writes to
+`dist/browser/index.html`, so after `npm --workspace frontend run build`
+the file is present and the SPA is served. The reported symptom was a
+snapshot taken before the build artefact existed; rebuilding resolves it.
