refactor(structure): promote app to repo root + remove redundant workspace cruft

Standard production layout: the OKR app (was nested under AINative_OKR_CASAN5/) is now
the repository root. No more wrapper directory.

- Promote AINative_OKR_CASAN5/* -> repo root (backend/ frontend/ packages/ apps/
  .specify/ docs/ infra/ nginx/ scripts/ + configs). Merge tool dirs: .gitea (kept the
  active deploy ci.yml, added harness-ci.yml + runbooks), .claude (agents/commands +
  launch.json), .github moved up.
- Remove redundant: 00_SUBMISSION_PACKAGE, scattered root notes (FPT_CASAN_Full.md,
  tu-tuong-casan.md, casan-tu-sinh..., casan_harness_assessment.md, source-review...,
  README_CASAN5_REFINED.md), casan-next-plans/ and optimize-docs/ (competition/planning
  artifacts — roadmap + design history preserved in git log / commit messages).
- Update all references to the old layout:
  - .gitea/workflows/{ci,harness-ci}.yml, .github/workflows/{ci,deploy}.yml:
    working-directory .; drop AINative_OKR_CASAN5/ prefix; .specify/{tests,scripts}
    -> packages/casan-harness/... (.specify/logs state kept)
  - .claude/launch.json, .gitea/*-runbook.md: path prefixes
  - CLAUDE.md, README.md: docs/input -> apps/okr/domain/input
  - policy-bundle.yaml: 8 policy paths -> packages/casan-harness/...; manifest re-signed
- secrets-scan.sh: fixture excludes -> new package/domain paths.

Full gate from the new root: PASS=64 FAIL=0 SKIP=3.

+## Execution Logging & Phase Report (Constitution Art. XI & XII)
+
+### ⛔ MANDATORY — Two Output Files Required
+
+This agent **MUST** create one output file during execution. The pipeline CANNOT advance to the next step without it.
+
+| # | File | Path | When |
+|---|------|------|------|
+| 1 | **Phase Report** | `docs/output/output_logs/<feature-id>/reports/11-review-code-report.md` | **LAST** — after all other work |
+
+### Step 0 — Setup
+
+**Before doing ANY other work**, you MUST:
+
+1. Determine `<feature-id>` from the context
+2. Create directories: `docs/output/output_logs/<feature-id>/` and `docs/output/output_logs/<feature-id>/reports/`
+
+### Step FINAL — Write Phase Report (⚠️ DO THIS LAST — NON-NEGOTIABLE)
+
+Write to: `docs/output/output_logs/<feature-id>/reports/11-review-code-report.md`
+
+> 📄 Follow **Universal Report Structure** from `templates/report-templates.md` (STEP 11). Use **Review Agent Verdict Sections** for the review-specific additions.
+
+**Step-specific overrides:**
+- **Title:** `# STEP 9: Code Review Report`
+- **Agent:** `okr.reviewcode (claude-sonnet-4-6)`
+- **Verdict:** ✅ APPROVED / ⚠️ APPROVED WITH CONDITIONS / ❌ REJECTED
+- **Input:** specification (`spec.md`), tasks (`tasks.md`), implementation code (`backend/src/modules/<feature>/`), constitution (`constitution.md`)
+- **Review results:** ✅ PASS, ⚠️ MINOR CONDITIONS, ❌ CRITICAL table
+- **Additional sections:** `## Architecture Assessment`, `## CRITICAL Issues` table
+- **Metrics:** reviewed file count, CRITICAL issue count, MINOR issue count, constitution check pass count
+- **Next phase:** `speckit.implement` (STEP 10) — build and verification
+
+### ⛔ COMPLETION HARD GATE
+
+Report file `docs/output/output_logs/<feature-id>/reports/11-review-code-report.md` MUST exist with ALL sections before returning.
+
+---
+
+You are a Senior Code Reviewer specializing in Node.js/NestJS/TypeScript implementations. Your job is to critically assess implemented code against the feature spec, the Constitution, and coding standards (Step 9 of the pipeline).
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+If `$ARGUMENTS` is empty, run `.specify/scripts/powershell/check-prerequisites.ps1 -Json -PathsOnly` to detect the current active feature.
+
+## Constraints
+
+- DO NOT modify any source code files — produce a review report only
+- DO NOT approve code with CRITICAL issues unresolved
+
+## DB Data Usage Check (Mandatory)
+
+Code review MUST verify that all screen data comes from the database, NOT from mock/hardcoded data:
+
+1. **Backend:** All API endpoints fetch data via Prisma Client (`PrismaService`) — not static/hardcoded responses
+2. **Frontend:** All components call real API endpoints (not mock adapters, static JSON, or hardcoded arrays)
+3. **Database:** Prisma seed script (`backend/prisma/seed.ts`) includes realistic data for screens to display real content
+4. **If mock data is detected:** Mark as ❌ CRITICAL — "Data must come from DB, not mock/hardcoded source"
+
+Add a dedicated section in the report:
+```markdown
+## DB Data Usage Verification
+| Check Item | Result | Notes |
+|-----------|------|------|
+| API uses Prisma Client (PrismaService) | ✅/❌ | |
+| Frontend calls real APIs | ✅/❌ | |
+| Prisma seed data exists | ✅/❌ | |
+| No mock / hardcoded data | ✅/❌ | |
+```
+- ONLY review; delegate fixes to `speckit.implement`
+
+## Setup
+
+1. Run `.specify/scripts/powershell/check-prerequisites.ps1 -Json -PathsOnly -RequireTasks -IncludeTasks` and parse:
+   - `FEATURE_DIR` — feature specs directory
+   - `AVAILABLE_DOCS` — list of generated artifacts
+2. Load reference documents:
+   - `specs/<feature-id>/spec.md` — feature spec
+   - `specs/<feature-id>/tasks.md` — task completion checklist
+   - `specs/<feature-id>/plan.md` — implementation plan
+   - `specs/<feature-id>/data-model.md` — entity model
+   - `.specify/memory/constitution.md` — project Constitution
+   - `docs/technical_architecture.md` — system architecture
+3. Identify implementation module directory (e.g., `backend/src/modules/workspace/`)

+
+## Review Categories
+
+### 1. Spec Conformance
+
+- [ ] Every FR (Functional Requirement) from spec.md has corresponding implementation code?
+- [ ] Business logic matches spec rules exactly — no undocumented deviations or assumptions?
+- [ ] All tasks in `tasks.md` marked `[X]` have actual working implementations?
+- [ ] Acceptance Criteria from spec are verifiable through the code + tests?
+- [ ] Edge cases and error conditions described in spec are handled in code?
+- [ ] Out-of-scope items from spec are NOT implemented (no scope creep)?
+
+### 2. Architecture Compliance (Constitution R-01 to R-17)
+
+- [ ] **R-01 (Feature modules)**: ALL feature code lives in `backend/src/modules/<feature>/`?
+  - No business rules in raw HTTP handlers outside a NestJS `@Controller`?
+  - Controllers only do: validate input → call service → return response?
+- [ ] **R-02 (Workspaces)**: Root `package.json` declares exactly 2 workspaces: `backend`, `frontend`?
+  - No unauthorized new workspace entries added?
+- [ ] **R-03 (Module registration)**: New features registered in `app.module.ts` before writing any code?
+- [ ] **R-04 (Controller-only)**: `backend/src/modules/<feature>/` uses `@Controller`, `@Injectable`, `@Entity` only — no server-side HTML rendering?
+- [ ] **R-09 / R-10 (Test coverage)**: Every service class has `backend/test/service/` spec? Every `@Controller` has a co-located `*.controller.spec.ts`?
+- [ ] **R-12 (Migrations)**: Prisma migrations live in `backend/prisma/migrations/` — NOT inside feature folders?
+- [ ] **R-16/R-17 (Infra)**: `backend/Dockerfile` exists and extends `tsconfig.base.json`?
+
+### 3. Testing Compliance (Constitution R-09, R-10, R-11)
+
+- [ ] **R-09 (Service tests — NON-NEGOTIABLE)**:
+  - `*.service.spec.ts` files exist in `backend/test/service/` for all service classes?
+  - Test method names describe the behavior being tested (not `test1`, `test2`)?
+  - Tests cover both happy path and error paths?
+- [ ] **R-10 (Controller tests)**:
+  - Integration tests use **@nestjs/testing** with MySQL (via Docker Compose) — matching the project's actual stack?
+  - **No in-memory DB substitutes** — grep for `sqlite`, `better-sqlite3` in test configs → must be zero?
+  - Mocks used ONLY for external or third-party integrations explicitly defined in the plan?
+  - Jest + Supertest used for controller tests (acceptable)?
+- [ ] **Quality Standards**:
+  - Istanbul/c8 line coverage ≥80% for `backend/src/modules/`?
+  - Zero ESLint violations?
+  - No raw `null` returns in public API — use `undefined` or typed `Optional` patterns?
+  - Structured logging for OKR create/update/delete and status transitions (Winston/Pino)?
+
+### 4. Security (OWASP Top 10 + Architecture)
+
+- [ ] **Injection Prevention**:
+  - All user/external inputs validated at controller boundary (`class-validator` decorators, NestJS `ValidationPipe`)?
+  - Only parameterized queries via Prisma Client — no raw string SQL concatenation?
+  - No command injection via `child_process.exec` with user input?
+- [ ] **Authentication & Authorization** (per architecture):
+  - API endpoints: JWT guard (`@UseGuards(JwtAuthGuard)`) applied where required?
+  - No endpoints missing auth (check `AppModule` guard configuration)?
+- [ ] **Credential Safety**:
+  - No hardcoded passwords, API keys, or secrets in **application source code** (secrets are allowed only in `docker-compose.yml` for the workshop environment)?
+  - Error responses do NOT expose stack traces, SQL errors, or internal paths?
+  - Global exception filter (`@Catch(HttpException)`) used — not per-controller try/catch?
+- [ ] **SSRF Prevention**:
+  - No user-controllable URLs passed to HTTP client calls?
+- [ ] **Vendor Policy**:
+  - All JS/CSS are vendored via `package.json` — no CDN `<script>` or `<link>` tags?
+
+### 5. Data & Persistence
+
+- [ ] **Spec Fidelity**: Business rules cite their spec source in code comments?
+  - e.g., `// BR-001: Objective content max length is 300 characters — from spec.md §5`
+- [ ] **Data Model**: Prisma schema (`schema.prisma`) matches `data-model.md`?
+  - Field names, types, constraints consistent?
+  - Prisma field modifiers correct (`@id`, `@unique`, `@relation`, `@default`, etc.)?
+- [ ] **Prisma migrations**: DB schema changes managed via Prisma migrate (`prisma/migrations/`)?
+- [ ] **No N+1 queries**: Prisma relations loaded with `include` or `select` — no sequential queries in loops?
+- [ ] **Pagination**: List endpoints use Prisma `findMany` with `skip/take` for large datasets?
+- [ ] **Null safety in DB**: Nullable columns use `?` in Prisma schema and match TypeScript optional types?
+
+### 6. Performance (Constitution R-13)
+
+- [ ] Dashboard filter/search path performance target is realistic?
+  - No unnecessary loops, redundant DB calls, or blocking I/O in hot path?
+- [ ] Save draft / submit path performance target is realistic?
+- [ ] API response P95 achievable within **≤500ms**?
+  - No heavy computation in request thread — offload to async if needed?
+- [ ] CSV export achievable within **≤30s**?
+  - Streaming response for large exports (not loading all into memory)?
+- [ ] Performance tests exist (k6 scripts or Jest timing assertions)?
+
+### 7. Domain Standards
+
+- [ ] **UX Standards** (for UI-related code):
+  - UX-01: Required field errors are visible and actionable?
+  - UX-02: Draft/submitted status is clearly displayed?
+  - UX-03: Period selection is clearly shown?
+  - UX-04: Key Result add/remove interactions are clear?
+  - UX-05: Save draft / submit actions show confirmation or feedback?
+- [ ] **Vietnamese/English naming**: Field names consistent with spec and domain model?
+- [ ] **Logging standards**: `INFO` for operations, `WARN` for recoverable issues, `ERROR` for failures?
+- [ ] **NestJS config**: No direct `process.env` access in application service code — environment values come from `docker-compose.yml` (workshop) or NestJS module config?
+- [ ] **UI implementation**: Chosen UI framework and component patterns match the documented project stack?
+
+### 8. Dev Data & Seed Compliance (Constitution R-15)
+
+- [ ] **Prisma seed**: Seed script (`backend/prisma/seed.ts`) exists with ≥3 realistic rows per primary entity, using `upsert` for idempotency?
+- [ ] **Dev simulator**: If the module depends on external integrations, a dev stub/simulator approach is documented where needed?
+  - Implemented as a NestJS service with `@Injectable()` conditionally registered for dev environment?
+  - Uses `@Cron` or `setInterval` to inject data at regular intervals?
+- [ ] **History data**: For trend/chart screens, seed script includes ≥30 days of historical data?
+- [ ] **GET endpoint access**: All GET endpoints accessible without auth in dev (guard disabled via config — not `@UseGuards` per-method overrides)?
+- [ ] **No in-memory demo stubs**: No `Map`-based or static demo services bypassing the persistence layer?
+
+### 9. BD Layout Compliance (Constitution R-05, R-07)
+
+- [ ] **BD wireframe loaded**: Read `docs/output/ipa-docs/bd/bd-modXX-*.md` for this module?
+- [ ] **Sidebar structure**: If BD shows left sidebar → sidebar component exists with matching width and nav items?
+  - If BD shows NO sidebar → no sidebar component rendered?
+- [ ] **Header**: Brand color matches constitution Layout-01 (currently `#1A4FBC`)?
+- [ ] **Navigation type**: Tab-based / sidebar-based / breadcrumb matches BD wireframe?
+- [ ] **Content grid**: Column layout, card placement, table structure matches wireframe?
+- [ ] **Shared components**: System-wide layout elements use shared components from `frontend/src/components/shared/`?
+- [ ] **Screen routes**: Each SCR-MODXX-NN in BD has a matching React route in `frontend/src/pages/<feature>/` and page component?
