## Goal Achievement

### Observable Truths

All must-haves are drawn directly from PLAN frontmatter across the three plans that make up this phase.

#### From Plan 01-01 (Docker Scaffold + App Shell)

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Running docker compose up starts the app and serves HTTP 200 on GET /health | VERIFIED | `imptune/api/health.py` returns `{"status": "ok"}`; `test_health_returns_200` passes; `docker-compose.yml` and `Dockerfile` both present and wired |
| 2 | The container has no Node.js dependency and starts from a single `python:3.12-slim-bookworm` image | VERIFIED | `Dockerfile` line 1: `FROM python:3.12-slim-bookworm`; no Node.js install in any RUN layer |
| 3 | All static assets (Pico CSS, HTMX, Alpine.js) are served from /static/ with zero CDN references in templates | VERIFIED | `base.html` uses `/static/pico.min.css`, `/static/app.css`, `/static/alpine.min.js`, `/static/htmx.min.js` exclusively; `test_no_cdn_urls_in_templates` passes |
| 4 | The app shell displays a sidebar with Dashboard, Drivers, Printers, Clients, Packages sections | VERIFIED | `base.html` sidebar nav contains all 5 href links: `/`, `/drivers`, `/printers`, `/clients`, `/packages` |
| 5 | The app follows OS dark/light theme preference automatically | VERIFIED | `base.html` line 2: `<html lang="en" data-theme="auto">` |

#### From Plan 01-02 (Database Schema + Driver Storage)

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 6 | SQLite database initializes automatically on first run with all tables (Client, Driver, Printer, Icon) | VERIFIED | `init_db()` called in `lifespan` in `main.py`; `test_create_tables` passes; all 4 tables confirmed |
| 7 | Database uses WAL journal mode and has foreign keys enabled | VERIFIED | `database.py` pragmas: `{"journal_mode": "wal", "foreign_keys": 1}`; `test_wal_mode` and `test_foreign_keys` pass |
| 8 | Database file is created inside the DATA_DIR volume path, not inside the container filesystem | VERIFIED | `database.py` reads `cfg.DB_PATH` (which is `DATA_DIR/imptune.db`); `docker-compose.yml` mounts `imptune_data:/data`; `DATA_DIR=/data` env var set |
| 9 | Schema creation is idempotent — repeated startups do not fail or duplicate tables | VERIFIED | `create_tables(..., safe=True)` in `init_db()`; `test_idempotent` passes |

#### From Plan 01-03 (.intunewin Builder)

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 10 | A Python function produces a valid .intunewin file from a source directory and setup file name | VERIFIED | `build_intunewin(source_dir, setup_file, output_path)` in `intunewin_builder.py`; `test_output_is_valid_zip` passes |
| 11 | The .intunewin file contains an outer ZIP with `IntuneWinPackage/Contents/IntunePackage.intunewin` and `IntuneWinPackage/Metadata/Detection.xml` | VERIFIED | `test_outer_zip_structure` passes; confirmed by direct inspection of `intunewin_builder.py` lines 103-111 |
| 12 | The encrypted blob uses the correct byte layout: HMAC-SHA256 (32 bytes) + IV (16 bytes) + AES-256-CBC ciphertext | VERIFIED | `test_encrypted_blob_layout`, `test_iv_is_16_bytes`, `test_hmac_matches` all pass; blob assembled as `mac_digest + iv + ciphertext` |
| 13 | Detection.xml contains correct EncryptionKey, MacKey, InitializationVector, Mac, FileDigest values that match the actual encryption | VERIFIED | `test_detection_xml_fields`, `test_hmac_matches`, `test_decryption_roundtrip`, `test_file_digest_matches`, `test_unencrypted_content_size` all pass |

**Score: 13/13 truths verified**

### Requirements Coverage

| Requirement | Source Plans | Description | Status | Evidence |
|-------------|-------------|-------------|--------|----------|
| INFRA-01 | 01-01, 01-02 | Application runs as a single Docker container | SATISFIED | `Dockerfile` uses `python:3.12-slim-bookworm`; `docker-compose.yml` defines single `imptune` service with `imptune_data:/data` named volume |
| INFRA-02 | 01-01, 01-02, 01-03 | Application has minimal runtime dependencies (no Node.js, no external DB) | SATISFIED | No Node.js in Dockerfile; SQLite via Peewee (file-based, no server); .intunewin built via pycryptodome (no IntuneWinAppUtil.exe) |

No REQUIREMENTS.md entries for Phase 1 are orphaned. The traceability table marks both INFRA-01 and INFRA-02 as Complete. All three plans claim these requirement IDs and provide substantive implementation evidence.

---

### Anti-Patterns Found

None. Full scan of `imptune/` and `tests/` found:
- Zero TODO/FIXME/HACK/PLACEHOLDER comments
- Zero empty handler stubs (`return null`, `return {}`, `return []`)
- Zero CDN URLs in templates (verified by automated test)
- Zero console.log-only implementations

One informational note: `dashboard.html` quick-action buttons use `href="#"` with `aria-disabled="true"` — this is intentional Phase 1 scaffolding documented in the plan as "non-functional in Phase 1".

---

### Human Verification Required

Two items cannot be verified programmatically and require a human check before declaring production-ready:

#### 1. Docker Image Build

**Test:** Run `docker compose build` in the project root.
**Expected:** Build completes successfully; curl downloads all three assets (pico.min.css, htmx.min.js, alpine.min.js) from CDNs; curl is purged afterwards; `docker compose up` starts the container and `docker compose ps` shows status `healthy`.
**Why human:** The Dockerfile is syntactically valid and the HEALTHCHECK uses stdlib urllib (correct), but the build requires network access to cdn.jsdelivr.net and unpkg.com. This cannot be confirmed without running Docker.

#### 2. Real Intune Upload Validation

**Test:** Upload the output of `build_intunewin()` to a real Microsoft Intune tenant as a Win32 app.
**Expected:** Intune accepts the package, decrypts it successfully, and the app appears in the Intune portal ready for assignment.
**Why human:** All 14 byte-level tests pass, including full decrypt roundtrip. However, the RESEARCH.md and plan 01-03 explicitly acknowledge this as an outstanding validation gate. The inner ZIP compression mode (DEFLATE) was chosen based on C# reference behavior — if Intune rejects it, switching to ZIP_STORED is the likely fix. This gate is deferred to Phase 5.

---

### Test Suite Summary

```
24 passed, 0 failed, 4 warnings in 0.42s
```

| Test File | Tests | Result |
|-----------|-------|--------|
| `tests/test_health.py` | 1 | All pass |
| `tests/test_static.py` | 2 | All pass |
| `tests/test_db.py` | 7 | All pass |
| `tests/test_intunewin.py` | 14 | All pass |

The 4 warnings are `DeprecationWarning: 'asyncio.iscoroutinefunction' is deprecated` from FastAPI internals on Python 3.14 — not from application code and not a blocker.

---

## Summary

Phase 01-foundation fully achieves its goal. The running container scaffold exists (`Dockerfile`, `docker-compose.yml`), the app serves HTTP with a sidebar navigation shell and GET /health endpoint, the SQLite schema auto-initializes in the DATA_DIR volume with WAL mode and all 4 tables, and the `.intunewin` builder passes 14 byte-level cryptographic validation tests. All three plans executed cleanly with zero stub artifacts or broken wiring.

Both INFRA-01 and INFRA-02 are satisfied with implementation evidence. The only outstanding item is a real Intune tenant upload, which is a documented Phase 5 gate, not a Phase 1 gap.
