<objective>
Create the Docker container scaffold, FastAPI app shell with sidebar navigation, health endpoint, and all baked-in static assets (Pico CSS, HTMX, Alpine.js). This is the foundation every subsequent plan builds on.
Purpose: Establish the running container and app shell that satisfies INFRA-01 (single Docker container) and INFRA-02 (no Node.js, no external DB). All subsequent phases add features to this scaffold.
Output: A buildable Docker image that starts, serves the app shell on localhost:8000, and passes healthcheck.

Create the full project scaffold following the architecture from RESEARCH.md. The app package is `imptune/` (not top-level modules).
**Dockerfile** (python:3.12-slim-bookworm base):
- WORKDIR /app
- Single RUN layer: apt-get install curl, mkdir -p /app/imptune/static, download Pico CSS v2 (pico.min.css), HTMX 2.x (htmx.min.js), Alpine.js 3.x (alpine.min.js) into /app/imptune/static/ using curl with --fail flag, then purge curl and clean apt cache
- COPY requirements.txt and pip install --no-cache-dir
- COPY imptune/ into /app/imptune/ and other root files
- VOLUME ["/data"]
- HEALTHCHECK using python stdlib urllib (not curl): `python -c "import urllib.request; urllib.request.urlopen('http://localhost:8000/health')"`
- EXPOSE 8000
- CMD ["uvicorn", "imptune.main:app", "--host", "0.0.0.0", "--port", "8000"]
**docker-compose.yml**:
- Service `imptune`, build context `.`, ports 8000:8000, volume `imptune_data:/data`, restart unless-stopped, env DATA_DIR=/data
**requirements.txt** (all dependencies for phases 1-5):
- fastapi==0.115.*, uvicorn[standard]==0.30.*, jinja2==3.1.*, python-multipart==0.0.9, pycryptodome==3.20.*, python-dotenv==1.0.*, peewee==3.17.*
**imptune/config.py**:
- Load DATA_DIR from env (default "/data"), PORT from env (default 8000)
- Derive DB_PATH as DATA_DIR/imptune.db, DRIVERS_DIR as DATA_DIR/drivers
**imptune/main.py**:
- Create FastAPI app (title="ImpTune")
- Mount StaticFiles from pathlib.Path(__file__).parent / "static" at "/static"
- Set up Jinja2Templates pointing to imptune/templates/
- Include health router and pages router
- Add startup event that creates DATA_DIR and DRIVERS_DIR directories if they don't exist
**imptune/api/health.py**:
- GET /health returning {"status": "ok"}
**imptune/api/pages.py**:
- GET / returning dashboard.html template (sync def, not async)
- Pass empty recent_printers=[] and recent_packages=[] context for now
**imptune/templates/base.html**:
- html lang="en" data-theme="auto" (Pico CSS auto dark/light)
- Head: meta charset, viewport, title "ImpTune", link to /static/pico.min.css, link to /static/app.css, script defer for alpine.min.js, script for htmx.min.js
- Body: flex container with persistent left sidebar nav and main content area
- Sidebar: flat equal-weight nav links for Dashboard (/), Drivers (/drivers), Printers (/printers), Clients (/clients), Packages (/packages). Use semantic nav element. Active link highlighted.
- Main: container class wrapping {% block content %}{% endblock %}
**imptune/templates/dashboard.html**:
- Extends base.html
- Quick action buttons at top: "New Printer", "Upload Driver", "Export Package" (links, non-functional in Phase 1 — link to # with disabled state)
- Recent activity section below: empty state message "No printers configured yet" and "No packages exported yet"
**imptune/static/app.css** (under 50 lines):
- Sidebar layout: flex, sidebar fixed width ~220px, main flex-grow
- Sidebar nav styling: vertical link list, active state highlight
- Quick action button row styling
- Keep minimal — Pico CSS handles most styling
All __init__.py files: empty or minimal.

# Phase 1, Plan 01: Docker Scaffold and App Shell Summary
**FastAPI app with Pico CSS sidebar shell, offline-baked static assets (HTMX, Alpine.js), GET /health, and 3-test green suite — all in a single python:3.12-slim-bookworm container**
## Performance
- **Duration:** 3 min
- **Started:** 2026-04-10T09:23:15Z
- **Completed:** 2026-04-10T09:26:30Z
- **Tasks:** 2
- **Files modified:** 17
## Accomplishments
- Docker scaffold with python:3.12-slim-bookworm base; curl downloads Pico CSS v2, HTMX 2.x, Alpine.js 3.x at build time and purges curl — zero CDN at runtime
- FastAPI app with asynccontextmanager lifespan, StaticFiles mount, health router, and dashboard page router
- Sidebar layout template (`base.html`) with `data-theme="auto"` for OS dark/light preference and 5 flat equal-weight nav sections
- Test suite: 3 passing tests covering health endpoint, no-CDN-URLs scan, and dashboard 200 response
## Task Commits
1. **Task 1: Docker scaffold, FastAPI app shell, templates** - `bd4e132` (feat)
2. **Task 2: Test scaffold, health and static tests** - `34c7cb3` (feat)
## Files Created/Modified
- `Dockerfile` — python:3.12-slim-bookworm, curl-baked static assets, stdlib healthcheck, uvicorn CMD
- `docker-compose.yml` — imptune_data:/data volume, DATA_DIR env, restart unless-stopped
- `requirements.txt` — all phase 1-5 deps (fastapi, uvicorn, jinja2, peewee, pycryptodome, etc.)
- `requirements-dev.txt` — pytest, httpx
- `imptune/main.py` — FastAPI app with lifespan, StaticFiles, router registration
- `imptune/config.py` — DATA_DIR/PORT env loading, DB_PATH/DRIVERS_DIR derivation
- `imptune/api/health.py` — GET /health → {"status": "ok"}
- `imptune/api/pages.py` — GET / → dashboard.html (sync def, new TemplateResponse signature)
- `imptune/templates/base.html` — data-theme="auto", /static/ assets only, sidebar nav
- `imptune/templates/dashboard.html` — quick actions + empty state recent activity
- `imptune/static/app.css` — sidebar flex layout, active link highlight, quick action styling
- `tests/conftest.py` — client and tmp_data_dir fixtures
- `tests/test_health.py` — health endpoint 200 test
- `tests/test_static.py` — no-CDN-URL scan + dashboard 200 test
## Decisions Made
- Used `asynccontextmanager lifespan` instead of deprecated `@app.on_event("startup")` — avoids DeprecationWarning on FastAPI 0.115+ / Python 3.13
- Used `TemplateResponse(request=request, name=..., context={...})` signature — the old positional dict form triggers a `TypeError: unhashable type: 'dict'` on Starlette 0.40+ due to LRUCache key behavior
- Static directory resolved from `pathlib.Path(__file__).parent / "static"` — works in Docker and local dev without hardcoded paths
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 1 - Bug] Fixed Starlette TemplateResponse signature incompatibility**
- **Found during:** Task 2 (test_dashboard_returns_200 failed)
- **Issue:** `templates.TemplateResponse("dashboard.html", {"request": request, ...})` raises `TypeError: unhashable type: 'dict'` on Starlette 0.40+ — context dict used as LRUCache key
- **Fix:** Changed to `templates.TemplateResponse(request=request, name="dashboard.html", context={...})`
- **Files modified:** `imptune/api/pages.py`
- **Verification:** test_dashboard_returns_200 passes
- **Committed in:** `34c7cb3` (Task 2 commit)
**2. [Rule 1 - Bug] Replaced deprecated on_event with asynccontextmanager lifespan**
- **Found during:** Task 2 (DeprecationWarning on test run)
- **Issue:** `@app.on_event("startup")` is deprecated in FastAPI 0.95+ / Starlette 0.37+; triggers warning on every test run
- **Fix:** Replaced with `@asynccontextmanager async def lifespan(app)` passed to `FastAPI(lifespan=lifespan)`
- **Files modified:** `imptune/main.py`
- **Verification:** Tests pass with zero warnings
- **Committed in:** `34c7cb3` (Task 2 commit)
---
**Total deviations:** 2 auto-fixed (both Rule 1 - Bug)
**Impact on plan:** Both fixes required for compatibility with installed library versions. No scope creep.
## Issues Encountered
- Starlette's `TemplateResponse` API changed in 0.40.0 — old positional-dict form breaks silently until test run. Fixed inline.
## Next Phase Readiness
- App shell and health endpoint ready — next plan (01-02) can build the SQLite schema and Peewee models on this foundation
- Docker image can be built once assets are downloaded; local dev works without Docker via `python3 -m pytest` and direct uvicorn run
- No blockers for 01-02

<objective>
Create the full SQLite schema using Peewee ORM (all tables for phases 1-5) and the content-addressed driver storage abstraction. Wire database initialization into the FastAPI startup event.
Purpose: Establish the data layer that all subsequent phases depend on. The full schema is created upfront per the locked user decision, so later phases only add routes and logic — not schema changes. Satisfies INFRA-01 (SQLite auto-init) and INFRA-02 (no external DB).
Output: Working database module with all models, driver storage helper, and startup wiring.

Modify the existing imptune/main.py (created by plan 01-01) to add database initialization on startup:
- Import init_db from imptune.db.database
- In the existing startup event handler, add a call to init_db() AFTER the directory creation logic
- This ensures the SQLite database is created inside DATA_DIR (which was just created/verified)
- Keep all existing code (StaticFiles mount, router includes, directory creation) — only ADD the init_db() call
Do NOT use async def for the startup handler — Peewee is sync-only. Use regular def with FastAPI's @app.on_event("startup") which already exists from plan 01-01.

# Phase 1 Plan 2: Database Schema and Driver Storage Summary
**Peewee ORM with deferred SQLiteDatabase, full 4-table schema (Client/Driver/Printer/Icon) for all phases, and SHA256-deduplicating DriverStore — wired into FastAPI lifespan**
## Performance
- **Duration:** ~3 min
- **Started:** 2026-04-10T09:29:54Z
- **Completed:** 2026-04-10T09:32:07Z
- **Tasks:** 2 (Task 1 with TDD + Task 2)
- **Files modified:** 7
## Accomplishments
- Full Peewee ORM schema with 4 tables covering all phases 1-5 (locked-in upfront design decision)
- WAL journal mode and foreign_keys pragma enforced via init_db() on every startup
- Deferred database pattern allows tests to safely redirect DB_PATH to tmp dirs without module reloads
- DriverStore provides SHA256 content-addressed storage with automatic deduplication on write
- init_db() integrated into FastAPI lifespan — database auto-creates at DATA_DIR/imptune.db on startup
## Task Commits
Each task was committed atomically:
1. **Task 1: Peewee models, database init, and driver storage** - `dea4148` (feat — TDD GREEN)
2. **Task 2: Wire database init into FastAPI startup** - `88d9c5f` (feat)
**Plan metadata:** (docs commit follows)
_Note: TDD — tests written first (RED), then implementation (GREEN). No separate refactor pass needed._
## Files Created/Modified
- `imptune/db/__init__.py` - Package marker
- `imptune/db/database.py` - Deferred SqliteDatabase instance + init_db() with WAL/FK pragmas
- `imptune/db/models.py` - BaseModel, Client, Driver, Printer, Icon ORM models
- `imptune/storage/__init__.py` - Package marker
- `imptune/storage/driver_store.py` - SHA256 content-addressed DriverStore class
- `tests/test_db.py` - 7 TDD tests (table creation, WAL, FK, idempotency, save, dedup, get_path)
- `imptune/main.py` - Added import and call to init_db() in lifespan
## Decisions Made
- **Deferred database pattern**: Used `SqliteDatabase(None)` + `db.init()` at runtime so pytest's `monkeypatch` on `imptune.config.DB_PATH` works without module reload side effects.
- **Lifespan over @app.on_event**: Plan text referenced `@app.on_event("startup")` but 01-01 established the lifespan pattern. Followed existing code — no deviation registered as this was alignment with an existing decision.
- **Full schema upfront**: All 4 tables created in phase 1 per user's locked decision, so phases 2-5 only add application logic.
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 3 - Blocking] Installed missing peewee package**
- **Found during:** Task 1 setup
- **Issue:** peewee was in requirements.txt but not installed in the active Python environment
- **Fix:** Ran `python -m pip install peewee==3.17.*`
- **Files modified:** None (environment only)
- **Verification:** `import peewee` succeeds, all 7 tests pass
- **Committed in:** Not committed (environment dependency install)
---
**Total deviations:** 1 auto-fixed (1 blocking — missing dependency)
**Impact on plan:** No scope creep. peewee install was a prerequisite, not new scope.
## Issues Encountered
- Plan Task 2 referenced `@app.on_event("startup")` but the existing `main.py` from plan 01-01 already uses `asynccontextmanager lifespan` (per a decision recorded in STATE.md). Added `init_db()` to the lifespan function instead — no regression.
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- Database layer complete — all ORM models importable and tested
- `init_db()` wired in — first app startup creates the database automatically in DATA_DIR
- DriverStore ready for driver upload routes (phase 3)
- All 24 tests pass (7 new + 17 existing), zero regressions

<objective>
Implement the Python-native .intunewin file builder as a time-boxed spike. This module generates .intunewin packages using AES-256-CBC encryption with HMAC-SHA256, producing the exact byte layout Intune expects.
Purpose: Validate the highest-risk unknown in the project — can Python generate a .intunewin file that Intune accepts? This spike runs independently of the web app and produces a standalone generator module reused in Phase 5. Supports INFRA-02 (no external binary dependencies like IntuneWinAppUtil.exe).
Output: A tested build_intunewin() function and comprehensive byte-level validation tests.

<action>
**imptune/generators/intunewin_builder.py**:
Implement build_intunewin(source_dir: str, setup_file: str, output_path: str) -> None following the skeleton from RESEARCH.md Pattern 3, with these specifics:
1. Create inner ZIP (DEFLATE compression) of all files in source_dir, preserving relative paths
2. Generate random keys: aes_key = os.urandom(32), mac_key = os.urandom(32), iv = os.urandom(16) — IV MUST be 16 bytes per the critical correction in RESEARCH.md
3. Encrypt with AES-256-CBC: cipher = AES.new(aes_key, AES.MODE_CBC, iv), ciphertext = cipher.encrypt(pad(plaintext, AES.block_size))
4. Compute HMAC-SHA256 of ciphertext using mac_key
5. Assemble encrypted blob: hmac_digest (32 bytes) + iv (16 bytes) + ciphertext
6. Compute file_digest = SHA256 of plaintext (the inner ZIP bytes before encryption)
7. Build Detection.xml with all required fields (see RESEARCH.md for exact schema). Use xml.etree.ElementTree for building and xml.dom.minidom for pretty printing. Set xmlns="http://schemas.microsoft.com/IntuneWin" on ApplicationInfo root.
8. Build outer ZIP (STORED compression) with two entries: IntuneWinPackage/Contents/IntunePackage.intunewin (the encrypted blob) and IntuneWinPackage/Metadata/Detection.xml
9. All base64 values in Detection.xml use standard base64 encoding (base64.b64encode)
**tests/test_intunewin.py**:
- Create a tmp_path fixture with a small test source directory (2-3 small text files, one named "install.ps1")
- Call build_intunewin(source_dir, "install.ps1", output_path) to generate the file
- Implement all tests from the behavior list above
- For the decryption roundtrip: extract EncryptionKey and IV from Detection.xml, use AES.new(key, AES.MODE_CBC, iv) to decrypt, unpad the result, verify it's a valid ZIP containing the original files
- For HMAC verification: extract MacKey from Detection.xml, compute hmac.new(mac_key, ciphertext, hashlib.sha256).digest(), compare to first 32 bytes of blob AND to Mac value in Detection.xml
The tests serve as the format specification — if they pass, the byte layout is correct. The only remaining validation is a real Intune upload (manual, Phase 5 gate).

# Phase 1 Plan 03: .intunewin Builder Summary
**Python-native .intunewin assembler using pycryptodome: AES-256-CBC encryption with HMAC-SHA256, producing the exact 48-byte header + ciphertext blob layout that Intune expects**
## Performance
- **Duration:** ~7 min
- **Started:** 2026-04-10T09:23:18Z
- **Completed:** 2026-04-10T09:25:32Z
- **Tasks:** 1 (TDD: RED + GREEN commits)
- **Files modified:** 4
## Accomplishments
- Implemented `build_intunewin(source_dir, setup_file, output_path)` as a standalone Python module requiring no external binary (INFRA-02)
- All 14 byte-level tests pass: outer ZIP structure, Detection.xml schema, IV/key sizes, HMAC-SHA256 verification, AES-256-CBC decryption roundtrip, file digest validation
- Confirmed critical RESEARCH.md correction: IV is 16 bytes (not 32 as incorrectly documented in STACK.md)
- Highest-risk unknown in Phase 1 is now validated at the byte-level; only a real Intune tenant upload remains outstanding
## Task Commits
Each task was committed atomically using TDD:
1. **RED — Failing tests** - `4d455e7` (test)
2. **GREEN — Implementation** - `25f82e6` (feat)
_TDD spike: failing tests committed first (RED), then implementation to pass (GREEN)._
## Files Created/Modified
- `imptune/generators/intunewin_builder.py` — build_intunewin() function, 111 lines, standalone module with no web framework dependency
- `imptune/generators/__init__.py` — generators package marker
- `tests/test_intunewin.py` — 14 byte-level tests organized into 4 test classes
- `tests/__init__.py` — tests package marker
## Decisions Made
- **IV is 16 bytes:** STACK.md stated 32 bytes — this is a documentation error. AES block size is always 16 bytes. pycryptodome raises `ValueError: IV must be 16 bytes long` with 32-byte IV. Implementation uses `os.urandom(16)`.
- **MacKey is 32 bytes:** svrooij articles do not specify exact MacKey size; chose 32 bytes (same as EncryptionKey) consistent with SvRooij.ContentPrep source behavior.
- **Inner ZIP uses DEFLATE:** Matches the C# reference implementation (.NET `ZipArchive` default). The conflicting "no compression" WebSearch result was treated as low-confidence (tertiary source); DEFLATE will be confirmed/corrected in the Phase 5 real Intune upload gate.
- **Real Intune validation deferred:** Pitfall 5 from RESEARCH.md is explicitly acknowledged — local byte-level tests confirm format structure, but the definitive validation requires a real Intune tenant upload in Phase 5.
## Deviations from Plan
None - plan executed exactly as written.
## Issues Encountered
None — all crypto operations succeeded on first implementation. pycryptodome correctly enforced 16-byte IV constraint (which would have caught the STACK.md documentation error if it had been used with 32 bytes).
## User Setup Required
None — no external service configuration required. The `.intunewin` format validation against a real Intune tenant is a manual gate in Phase 5, not a configuration step.
## Next Phase Readiness
- `build_intunewin()` is ready for use in Phase 5 (package export)
- Module is standalone — no dependency on FastAPI, SQLite, or any web framework
- Outstanding concern: byte-level format confidence is MEDIUM until a real Intune tenant upload confirms acceptance
- Blocker for Phase 5 only: access to a real Intune tenant for upload testing

# Phase 1: Foundation - Context
**Gathered:** 2026-04-10
**Status:** Ready for planning
<domain>
## Phase Boundary
A running Docker container with the app scaffold, SQLite data schema, and a validated .intunewin generation capability. This phase delivers the infrastructure skeleton that all subsequent phases build on. No user-facing features beyond the app shell.
</domain>
<decisions>
## Implementation Decisions
### App shell & navigation
- Persistent left sidebar with flat, equal-weight sections: Dashboard, Drivers, Printers, Clients, Packages
- Dashboard is the landing page: quick action buttons at top ("New Printer", "Upload Driver", "Export Package") plus recent printers/packages list below
- System/auto theme — follow OS dark/light preference (two color schemes)
### CSS & offline access
- Air-gapped deployment — no CDN access from the server, all assets must be bundled in the Docker image
- Use a lightweight pre-built CSS framework (e.g., Pico CSS) instead of Tailwind — no build step, just a static CSS file
- HTMX and Alpine.js downloaded during Docker image build (ADD/curl), baked into the image as static files
- All JS/CSS served from the container's static files directory — zero external requests at runtime
### Database schema
- Full schema created upfront in Phase 1 — all tables for phases 2-5 (drivers, printers, clients, icons)
- Peewee ORM for all database operations — matches SQLite single-writer model
- Schema auto-created on first run via Peewee's `create_tables()`
### Driver storage
- SHA256 content-addressed storage for driver files on the Docker volume
- Deduplication: same file uploaded twice results in one copy on disk
- SQLite stores the hash reference + original filename + metadata; filesystem stores the actual files
### Claude's Discretion
- Specific lightweight CSS framework selection (Pico CSS, Simple.css, or similar)
- Dashboard layout details and empty state design
- Exact color scheme for light and dark themes
- Project directory structure (guided by ARCHITECTURE.md research)
- .intunewin spike implementation details
</decisions>
<specifics>
## Specific Ideas
- Sidebar sections ordered as flat equals, not by workflow hierarchy — Dashboard is just another section, not a special landing
- Dashboard should get technicians moving immediately — quick actions are the primary UI element, recent activity is secondary
- The app runs on private MSP networks that may have no internet access at all — everything must work fully offline after the Docker image is built
</specifics>
<code_context>
## Existing Code Insights
### Reusable Assets
- None — greenfield project, no existing code
### Established Patterns
- None yet — Phase 1 establishes all patterns
### Integration Points
- ARCHITECTURE.md proposes the project structure: api/, services/, generators/, templates/, db/, storage/
- STACK.md defines all dependencies and version constraints
- .intunewin format documented in STACK.md (inner ZIP + AES-256-CBC encryption + Detection.xml + outer ZIP)

## Phase Requirements
| ID | Description | Research Support |
|----|-------------|-----------------|
| INFRA-01 | Application runs as a single Docker container | Docker scaffold plan (Dockerfile + docker-compose.yml); python:3.12-slim-bookworm base; no sidecar services |
| INFRA-02 | Application has minimal runtime dependencies (no Node.js, no external DB) | Pico CSS + HTMX + Alpine.js baked into image at build time; SQLite via Peewee (stdlib + one pip package); no Node build pipeline |
</phase_requirements>
---
## Summary
Phase 1 delivers three things: a running Docker container with the app scaffold, the complete SQLite schema initialized via Peewee, and a validated Python-native .intunewin generator. These are independent workstreams that can be built in parallel but must converge before Phase 2 starts.
The Docker scaffold is low-risk and well-understood. The base image is `python:3.12-slim-bookworm` (never Alpine — C-extension wheels fail on musl libc). All frontend assets (Pico CSS, HTMX, Alpine.js) are downloaded with `curl` during the Docker build and served as static files. There are zero external HTTP requests at container runtime — a hard requirement for air-gapped MSP networks.
The SQLite schema via Peewee is also straightforward, but the Phase 1 decision to create the full schema upfront (all tables for phases 2-5) means the models file must define every table now. The `.intunewin` format spike is the highest-risk item: the format is reverse-engineered (MEDIUM confidence), AES-256-CBC with HMAC-SHA256, and the Python implementation must be validated against a real Intune tenant before Phase 5 export work begins. A known documentation error exists: STACK.md states "32-byte IV" but the actual AES-CBC standard IV is 16 bytes — use 16 bytes in the implementation.
**Primary recommendation:** Build the Docker scaffold and schema in parallel. Treat the .intunewin spike as a time-boxed investigation (max 2 days) that ends in a real Intune upload test — not just local file creation.

## Standard Stack
### Core
| Library | Version | Purpose | Why Standard |
|---------|---------|---------|--------------|
| python:3.12-slim-bookworm | 3.12 (Debian 12) | Docker base image | LTS Python, Debian glibc (not musl), slim keeps image under 200 MB, pre-built C-extension wheels always work |
| FastAPI | 0.115.x | HTTP framework | Async-capable, Pydantic v2 validation, `TemplateResponse`, `FileResponse`, `StreamingResponse` built in |
| Uvicorn | 0.30.x | ASGI server | FastAPI's recommended server; `uvicorn[standard]` pulls in uvloop + httptools |
| Jinja2 | 3.1.x | HTML templating | Ships with FastAPI's template support; used for both HTML pages and PS script generation |
| Peewee | 3.17.x | ORM for SQLite | Sync-only ORM perfectly matched to SQLite single-writer model; `create_tables()` for schema auto-init |
| pycryptodome | 3.20.x | AES-256-CBC + HMAC-SHA256 | Required for .intunewin inner package encryption; import as `from Crypto.Cipher import AES` |
| python-dotenv | 1.0.x | Env-var config | Docker-level overrides without rebuilding (data dir, port, base URL) |
| python-multipart | 0.0.9 | Multipart file uploads | Required by FastAPI's `UploadFile`; always install alongside FastAPI for file upload routes |
### Supporting (Phase 1 specific)
| Library | Version | Purpose | When to Use |
|---------|---------|---------|-------------|

### Pattern 1: Docker Offline Asset Baking
**What:** Download CSS/JS assets with `curl` during `docker build` so they are baked into the image. No CDN access at container runtime.
**When to use:** Always — this is a hard requirement for air-gapped MSP networks.
**Example Dockerfile snippet:**
```dockerfile
FROM python:3.12-slim-bookworm
WORKDIR /app
# Install system deps and download frontend assets in one layer
RUN apt-get update && apt-get install -y --no-install-recommends curl \
&& mkdir -p /app/static \
&& curl -sLo /app/static/pico.min.css \
"https://cdn.jsdelivr.net/npm/@picocss/pico@2/css/pico.min.css" \
&& curl -sLo /app/static/htmx.min.js \
"https://unpkg.com/htmx.org@2/dist/htmx.min.js" \
&& curl -sLo /app/static/alpine.min.js \
"https://cdn.jsdelivr.net/npm/alpinejs@3/dist/cdn.min.js" \
&& apt-get purge -y curl && apt-get autoremove -y \
&& rm -rf /var/lib/apt/lists/*
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
COPY . .
VOLUME ["/data"]
HEALTHCHECK --interval=30s --timeout=5s --start-period=10s --retries=3 \
CMD python -c "import urllib.request; urllib.request.urlopen('http://localhost:8000/health')"
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000"]
```
**docker-compose.yml:**
```yaml
services:
imptune:
build: .
ports:
- "8000:8000"
volumes:
- imptune_data:/data
restart: unless-stopped
environment:
- DATA_DIR=/data
volumes:
imptune_data:
```
### Pattern 2: Peewee Schema Auto-Init
**What:** Define all tables (all phases) in `models.py`, auto-create on startup via `create_tables(safe=True)`.
**When to use:** On every container start — `safe=True` is idempotent (no-op if tables already exist).
**Example:**
```python
# db/database.py
from peewee import SqliteDatabase
import os
DB_PATH = os.environ.get("DATA_DIR", "/data") + "/imptune.db"
db = SqliteDatabase(DB_PATH, pragmas={"journal_mode": "wal", "foreign_keys": 1})
def init_db():
from db.models import Driver, Printer, Client, Icon
db.connect(reuse_if_open=True)
db.create_tables([Driver, Printer, Client, Icon], safe=True)
```
```python
# db/models.py
from peewee import *
from db.database import db
import datetime
class BaseModel(Model):
class Meta:
database = db
class Client(BaseModel):
name = CharField(unique=True)
created_at = DateTimeField(default=datetime.datetime.utcnow)
class Driver(BaseModel):
sha256 = CharField(unique=True, index=True) # content-addressed key
original_filename = CharField()
size_bytes = IntegerField()
uploaded_at = DateTimeField(default=datetime.datetime.utcnow)
# Phase 2 fields (populated during INF parsing):
driver_desc = CharField(null=True) # parsed DriverDesc from INF
inf_filename = CharField(null=True) # which INF file inside the ZIP
architecture = CharField(null=True) # x64, x86, arm64
has_cat_file = BooleanField(default=False)
class Printer(BaseModel):
name = CharField()
ip_address = CharField()
port_name = CharField()
client = ForeignKeyField(Client, backref="printers", null=True)
driver = ForeignKeyField(Driver, backref="printers", null=True)
duplex_mode = CharField(default="OneSided") # OneSided|TwoSidedLongEdge|TwoSidedShortEdge
color_mode = BooleanField(default=True)
paper_size = CharField(default="A4")
collate = BooleanField(default=True)
created_at = DateTimeField(default=datetime.datetime.utcnow)
updated_at = DateTimeField(default=datetime.datetime.utcnow)
class Icon(BaseModel):
printer = ForeignKeyField(Printer, backref="icons", unique=True)
sha256 = CharField()
original_filename = CharField()
size_bytes = IntegerField()
uploaded_at = DateTimeField(default=datetime.datetime.utcnow)
```
### Pattern 3: .intunewin File Assembly (Python-Native)
**What:** Assemble a valid .intunewin file in Python without IntuneWinAppUtil.exe.
**Verified byte layout (from svrooij.io decryption article):**
```
Encrypted blob layout:
[0:32] — HMAC-SHA256 of the ciphertext (32 bytes)
[32:48] — AES-256-CBC Initialization Vector (16 bytes — standard AES block size)
[48:] — AES-256-CBC ciphertext (padded to 16-byte boundary)
IMPORTANT: The IV is 16 bytes, not 32. STACK.md has a documentation error on this point.
```
**Detection.xml schema:**
```xml
<ApplicationInfo xmlns="http://schemas.microsoft.com/IntuneWin">
<Name>install.ps1</Name>
<UnencryptedContentSize>12345</UnencryptedContentSize>
<FileName>IntunePackage.intunewin</FileName>
<SetupFile>install.ps1</SetupFile>
<EncryptionInfo>
<EncryptionKey>base64(32-byte AES key)</EncryptionKey>
<MacKey>base64(32-byte HMAC key)</MacKey>
<InitializationVector>base64(16-byte IV)</InitializationVector>
<Mac>base64(32-byte HMAC-SHA256)</Mac>
<MacAlgorithm>SHA256</MacAlgorithm>
<ProfileIdentifier>ProfileVersion1</ProfileIdentifier>
<FileDigest>base64(SHA256 of plaintext ZIP)</FileDigest>
<FileDigestAlgorithm>SHA256</FileDigestAlgorithm>
</EncryptionInfo>
</ApplicationInfo>
```
**Outer ZIP structure:**
```
IntuneWinPackage/
├── Contents/
│ └── IntunePackage.intunewin ← the encrypted blob
└── Metadata/
└── Detection.xml ← encryption metadata
```
**Python assembly skeleton:**
```python

### Anti-Patterns to Avoid
- **Alpine Linux base image:** musl libc breaks pycryptodome and other C-extension wheels; use `python:3.12-slim-bookworm` only.
- **Downloading assets at container runtime:** Never use CDN links in HTML templates; all assets must be served from `/app/static/` which is baked into the image.
- **Tailwind CDN Play script in templates:** Per Tailwind docs, Play CDN is development-only. The locked decision already chooses Pico CSS — a pre-built static file that needs no CDN at runtime.
- **Storing the SQLite file inside the container filesystem:** Always mount `/data` as a named volume; SQLite must persist across container restarts.
- **`peewee.database.connect()` without WAL mode:** SQLite default journal mode is DELETE; enable WAL (`"journal_mode": "wal"`) so reads don't block writes during generation.
- **32-byte IV in .intunewin:** Standard AES-CBC IV is 16 bytes (AES block size). Using 32 bytes will produce a non-compliant file that Intune will reject. The STACK.md documentation has this wrong — use 16 bytes.
---
## Don't Hand-Roll
| Problem | Don't Build | Use Instead | Why |
|---------|-------------|-------------|-----|
| AES-256-CBC encryption | Custom AES implementation | `pycryptodome` (`from Crypto.Cipher import AES`) | Padding edge cases, IV handling, block alignment — stdlib `hashlib` does not provide AES |
| HMAC-SHA256 | Custom HMAC | Python stdlib `hmac.new(key, data, hashlib.sha256)` | Already in stdlib, correct constant-time comparison built in |
| SQLite schema management | Raw `CREATE TABLE IF NOT EXISTS` strings | Peewee `create_tables(safe=True)` | Migration safety, model-to-SQL mapping, foreign key management |
| Serving static files in FastAPI | Custom file-serving route | `app.mount("/static", StaticFiles(directory="static"))` | FastAPI's built-in `StaticFiles` handles ETags, range requests, content-type detection |
| Docker healthcheck HTTP request | curl (which may not be in final image) | Python one-liner: `python -c "import urllib.request; urllib.request.urlopen('http://localhost:8000/health')"` | Uses stdlib; no curl dependency in the slim image |
**Key insight:** pycryptodome handles all the crypto complexity. The hard part of the .intunewin spike is not the encryption itself — it's assembling the exact byte layout Intune expects and validating the output against a real tenant.
---
## Common Pitfalls
### Pitfall 1: Wrong IV Size in .intunewin (CRITICAL)
**What goes wrong:** Using a 32-byte IV instead of the correct 16-byte AES block size. The encrypted blob format is `[HMAC-SHA256 (32 bytes)] + [IV (16 bytes)] + [ciphertext]`. The total overhead is 48 bytes, not 64. Files built with a 32-byte IV will fail to decrypt on the Intune side.
**Why it happens:** STACK.md states "32-byte IV" — this is a documentation error. The decryption article confirms 16 bytes via `.NET's aes.IV.Length` (which is always 16 for AES).
**How to avoid:** Always use `iv = os.urandom(16)` and `AES.new(key, AES.MODE_CBC, iv)` where `len(iv) == 16`.
**Warning signs:** `ValueError: IV must be 16 bytes long` from pycryptodome if you use 32.
### Pitfall 2: Storing State in Container Filesystem
**What goes wrong:** Writing the SQLite file or driver ZIPs to `/app/` or `/tmp/`. Data disappears on container restart.
**Why it happens:** Default working directory in Docker is the app folder; developers forget to configure the volume.
**How to avoid:** Set `DATA_DIR=/data` env var. `docker-compose.yml` mounts `imptune_data:/data`. SQLite path must derive from `DATA_DIR`. Driver files go to `DATA_DIR/drivers/`. Never write persistent data outside the volume mount.
**Warning signs:** Fresh database on every `docker compose restart`.
### Pitfall 3: Alpine Base Image Breaking pycryptodome
**What goes wrong:** Using `python:3.12-alpine` as the Docker base. pycryptodome requires C extensions; the pre-built wheels target glibc, not Alpine's musl libc. pip will try to compile from source (requiring gcc/musl-dev) and often fails silently or produces a broken install.
**Why it happens:** Alpine is smaller, so it seems attractive for Docker images.
**How to avoid:** Use `python:3.12-slim-bookworm` (Debian 12). The final image will be slightly larger (~150-200 MB vs ~80 MB for Alpine) but will reliably install all C-extension packages.
### Pitfall 4: CDN Assets Requested at Runtime
**What goes wrong:** HTML templates reference `<link rel="stylesheet" href="https://cdn.jsdelivr.net/...">`. The container starts but the browser gets no CSS/JS when running on an air-gapped network.
**Why it happens:** Developers test on internet-connected machines where CDN works; the failure only manifests on offline deployments.
**How to avoid:** All `<link>` and `<script>` tags in templates must reference `/static/...` paths. The `curl` downloads in the Dockerfile must complete successfully — add `--fail` flag to `curl` so the build fails if a download fails rather than producing an empty file.
**Warning signs:** `curl` in Dockerfile without `--fail`; template contains `jsdelivr.net`, `unpkg.com`, or `cdnjs.com` URLs.
### Pitfall 5: .intunewin Spike Validated Only Locally
**What goes wrong:** The spike "works" because the developer verifies the file structure locally (zip contents, XML fields look right) but never uploads to a real Intune tenant. The actual validation — Intune accepting the file and successfully deploying it — is skipped. Phase 5 export is then built on an unvalidated format assumption.
**Why it happens:** Intune tenant access may not be immediately available; local file inspection seems sufficient.
**How to avoid:** The spike's only valid success criterion is: "file uploaded to a real Intune tenant, application shows as successfully uploaded (no format error)." Create a simple test package (one small file) and upload it. This validates the format; full driver packaging validation comes in Phase 5.
**Warning signs:** Spike task marked done without a real Intune upload test result.
### Pitfall 6: Peewee Called from FastAPI Async Context Without Executor
**What goes wrong:** Calling Peewee's synchronous ORM methods directly from a FastAPI `async def` route causes blocking of the event loop.
**Why it happens:** FastAPI encourages `async def` routes; Peewee is sync-only.
**How to avoid for Phase 1:** Use regular `def` (not `async def`) for FastAPI route handlers that touch the database. FastAPI runs sync handlers in a thread pool automatically. This is the correct pattern for Peewee + FastAPI — do not fight it with `run_in_executor`.
```python
# Correct: sync handler — FastAPI runs this in a thread pool
@router.get("/")
def dashboard():
recent = list(Printer.select().order_by(Printer.updated_at.desc()).limit(5))
return templates.TemplateResponse("dashboard.html", {"request": request, "printers": recent})
# Wrong for Phase 1: async handler calling sync Peewee
@router.get("/")
async def dashboard():
recent = list(Printer.select()...) # blocks the event loop
```
---
## Code Examples
### FastAPI App Entrypoint with Static Files and Templates
```python
# main.py
from fastapi import FastAPI
from fastapi.staticfiles import StaticFiles
from fastapi.templating import Jinja2Templates
from db.database import init_db
from api import pages
app = FastAPI(title="ImpTune")
# Serve baked-in static assets (pico.min.css, htmx.min.js, alpine.min.js)
app.mount("/static", StaticFiles(directory="static"), name="static")
# Register page routes
app.include_router(pages.router)
@app.on_event("startup")
def on_startup():
init_db() # creates all tables on first run, no-op if they exist
```
### Pico CSS Dark/Light Theme (OS preference)
```html
<!-- templates/base.html -->
<!DOCTYPE html>
<html lang="en" data-theme="auto">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>ImpTune</title>
<link rel="stylesheet" href="/static/pico.min.css">
<script defer src="/static/alpine.min.js"></script>
<script src="/static/htmx.min.js"></script>
</head>
<body>
<div style="display:flex">
<nav><!-- sidebar --></nav>
<main class="container">{% block content %}{% endblock %}</main>
</div>
</body>
</html>
```
`data-theme="auto"` instructs Pico CSS to follow the OS `prefers-color-scheme` media query automatically. No JavaScript needed.
### Docker healthcheck without curl
```dockerfile
HEALTHCHECK --interval=30s --timeout=5s --start-period=10s --retries=3 \
CMD python -c "import urllib.request; urllib.request.urlopen('http://localhost:8000/health')" || exit 1
```
### FastAPI health endpoint
```python
# api/health.py
from fastapi import APIRouter
router = APIRouter()
@router.get("/health")
def health():
return {"status": "ok"}
```

## State of the Art
| Old Approach | Current Approach | When Changed | Impact |
|--------------|------------------|--------------|--------|
| IntuneWinAppUtil.exe (Windows-only binary) | Python-native .intunewin (zipfile + pycryptodome) | 2023 — svrooij reverse-engineered format | Linux containers can now generate .intunewin without Wine or Windows base |
| Tailwind CDN Play in templates | Pre-built CSS framework (Pico CSS) served as static file | Phase 1 decision (2026-04-10) | Zero CDN dependency; air-gapped compatible |
| Gunicorn + Flask | Uvicorn + FastAPI | 2022-2024 ecosystem shift | Async-capable, Pydantic validation built in, less boilerplate |
| SQLAlchemy async | Peewee sync | Phase 1 decision | No async overhead for SQLite single-writer; simpler code |
**Deprecated/outdated:**
- `pycrypto`: Unmaintained since 2012, known CVEs. Use `pycryptodome` (maintained drop-in, `from Crypto.Cipher import AES`).
- `Tailwind Play CDN`: Explicitly marked as development-only by Tailwind docs. Not suitable for production or air-gapped environments.
- `Alpine Linux base image`: Avoid for any Python project using C-extension packages (pycryptodome, lxml, etc.).
---
## Open Questions
1. **Inner ZIP compression method (DEFLATE vs STORED)**
- What we know: The outer ZIP uses ZIP_STORED; the inner ZIP content appears to use DEFLATE (C# default, `volodymyrsmirnov/IntuneWin` uses default `.NET ZipArchive`). STACK.md says DEFLATE.
- What's unclear: Whether Intune requires DEFLATE specifically or accepts ZIP_STORED for the inner package. One search result stated "no compression used" which conflicts with STACK.md.
- Recommendation: Implement with `ZIP_DEFLATED` first (matches the reference implementation behavior). If Intune rejects it, try `ZIP_STORED`. The real Intune upload test in the spike will resolve this definitively.
2. **MacKey vs EncryptionKey sizes**
- What we know: EncryptionKey is 32 bytes (256-bit AES). MacKey is also described as a separate key for HMAC-SHA256. Standard HMAC-SHA256 can use any key size (SHA-256 block size is 64 bytes, but 32 bytes is common).
- What's unclear: Whether MacKey must be exactly 32 bytes or can differ. The svrooij articles don't state the MacKey size explicitly.
- Recommendation: Use `mac_key = os.urandom(32)` (32 bytes) — same size as the AES key, consistent with svrooij ContentPrep behavior.
3. **Pico CSS v2 sidebar layout**
- What we know: Pico CSS v2 is a classless/minimal framework with a `container` component and grid support. It does not have a built-in sidebar layout.
- What's unclear: Whether additional CSS will be needed for the persistent sidebar, or if Pico's grid/flex utilities suffice.
- Recommendation: Add a small `app.css` static file alongside `pico.min.css` for layout overrides (sidebar width, flex container). Keep it under 50 lines. This is Claude's discretion per CONTEXT.md.

- Docker scaffold pattern: HIGH — standard FastAPI Docker deployment, well-documented
- Peewee schema pattern: HIGH — official Peewee docs, straightforward sync ORM usage
- .intunewin format: MEDIUM — format confirmed by reverse-engineering; IV size corrected (16 bytes); inner ZIP compression TBD; must validate against real Intune tenant

**Research date:** 2026-04-10
**Valid until:** 2026-05-10 (stable ecosystem; .intunewin format validity: confirm during spike)
**Critical correction flagged:** STACK.md states "32-byte IV" for .intunewin encryption. Multiple sources (AES standard, svrooij.io decryption article citing `.NET aes.IV.Length = 16`) confirm the IV is 16 bytes. The planner must use 16 bytes in the spike implementation.

## Wave 0 Requirements
- [ ] `tests/__init__.py` — package marker
- [ ] `tests/conftest.py` — shared fixtures (temp dir, test DB path)
- [ ] `tests/test_health.py` — covers INFRA-01 HTTP health check
- [ ] `tests/test_db.py` — covers INFRA-01 schema init (all tables created, WAL mode)
- [ ] `tests/test_static.py` — covers INFRA-02 no-CDN-URLs assertion
- [ ] `tests/test_intunewin.py` — covers spike byte layout validation
- [ ] Framework install: `pip install pytest httpx` — add to `requirements-dev.txt`
*Existing infrastructure covers: None (greenfield project)*
---
## Manual-Only Verifications
| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| No Node.js in container | INFRA-02 | Requires running container inspection | `docker exec imptune which node` — should return nothing |
| .intunewin uploads to real Intune | (spike) | Requires Intune tenant access | Upload generated .intunewin via Intune portal, verify "successfully uploaded" status |

## Nyquist Record
> Audited 2026-04-13 by Claude (gsd-executor, plan 08-01). One row per Phase 1 success criterion derived from `milestones/v1.0-ROADMAP.md` Phase 1 goal + plan outcomes, cross-checked against `01-VERIFICATION.md` (13/13 observable truths verified on 2026-04-10) and `REQUIREMENTS.md` (INFRA-01, INFRA-02). Evidence cites committed tests, source lines, or the dated VERIFICATION report. Status values: `pass` / `fail-fix-v1.1` / `deferred-v1.2` / `wont-do`.
**Phase 1 goal (v1.0-ROADMAP.md):** *"A running Docker container with the app scaffold, data schema, and validated .intunewin generation capability."*
| # | Success Criterion | Observable Check | Evidence | Status | Notes |
|---|-------------------|------------------|----------|--------|-------|
| 1 | `docker compose up` starts the app and serves HTTP 200 on `GET /health` | `pytest tests/test_health.py::test_health_returns_200` returns the health payload | `tests/test_health.py::test_health_returns_200`; `imptune/api/health.py` (router returns `{"status": "ok"}`); 01-VERIFICATION.md row 1 (2026-04-10) | pass | INFRA-01. Docker image build itself is a human check (network to pico/htmx/alpine CDNs); covered by 01-VERIFICATION.md §"Human Verification Required" #1 and later exercised end-to-end during Phase 10 RTVAL-01 tenant upload (commit 7b37bdb referenced build 1c3f458). |
| 2 | Container has no Node.js dependency and starts from a single `python:3.12-slim-bookworm` image | `grep -n "^FROM" Dockerfile` returns only `FROM python:3.12-slim-bookworm`; no `node`/`npm` install layer | `Dockerfile` line 1; commit 34c7cb3 (`feat(01-01)`); 01-VERIFICATION.md row 2 | pass | INFRA-02 — "no Node.js" arm. |
| 3 | All static assets (Pico CSS, HTMX, Alpine.js) are served from `/static/` with zero CDN references in templates | `pytest tests/test_static.py::test_no_cdn_urls_in_templates` | `tests/test_static.py::test_no_cdn_urls_in_templates`; `imptune/templates/base.html` (4 `/static/` refs, zero `https://`); 01-VERIFICATION.md row 3 | pass | INFRA-02 — offline static arm. |
| 4 | App shell displays a sidebar with Dashboard, Drivers, Printers, Clients, Packages sections | Grep `imptune/templates/base.html` for the 5 nav hrefs (`/`, `/drivers`, `/printers`, `/clients`, `/packages`) | `imptune/templates/base.html` sidebar nav; 01-VERIFICATION.md row 4; Phase 7 `GET /packages` closure (commit landed under phase 07) proves the link is live | pass | Dashboard quick-action buttons intentionally `aria-disabled` in Phase 1 — documented, not a gap. |
| 5 | App follows OS dark/light theme preference automatically | Grep `imptune/templates/base.html` line 2 for `data-theme="auto"` | `imptune/templates/base.html` line 2; 01-VERIFICATION.md row 5 | pass | UI polish criterion from 01-01 plan frontmatter. |
| 6 | SQLite database initializes automatically on first run with all 4 tables (Client, Driver, Printer, Icon) | `pytest tests/test_db.py::test_create_tables` | `tests/test_db.py::test_create_tables`; `imptune/db/database.py::init_db`; `imptune/main.py` lifespan call (commit 88d9c5f); 01-VERIFICATION.md row 6 | pass | INFRA-01 — schema arm. Full 4-table upfront schema decision (v1.0 key decision). |
| 7 | Database uses WAL journal mode and has foreign keys enabled | `pytest tests/test_db.py::test_wal_mode` and `::test_foreign_keys` | `tests/test_db.py::test_wal_mode`, `::test_foreign_keys`; `imptune/db/database.py` pragmas `{"journal_mode": "wal", "foreign_keys": 1}`; 01-VERIFICATION.md row 7 | pass | |
| 8 | Database file is created inside the `DATA_DIR` volume path, not inside the container filesystem | Grep `imptune/db/database.py` for `cfg.DB_PATH`; grep `docker-compose.yml` for `imptune_data:/data`; grep for `DATA_DIR=/data` env | `imptune/db/database.py` (`db.init(cfg.DB_PATH, ...)`); `docker-compose.yml` named volume + env; 01-VERIFICATION.md row 8 | pass | Persistence-across-restart property. |
| 9 | Schema creation is idempotent — repeated startups do not fail or duplicate tables | `pytest tests/test_db.py::test_idempotent` | `tests/test_db.py::test_idempotent`; `create_tables(..., safe=True)` in `init_db()`; 01-VERIFICATION.md row 9 | pass | |
| 10 | A Python function produces a valid `.intunewin` file from a source directory and setup file name | `pytest tests/test_intunewin.py::test_output_is_valid_zip` | `tests/test_intunewin.py::test_output_is_valid_zip`; `imptune/generators/intunewin_builder.py::build_intunewin`; commit 25f82e6; 01-VERIFICATION.md row 10 | pass | Python-native .intunewin core decision (pycryptodome, no IntuneWinAppUtil.exe). |
| 11 | `.intunewin` output contains outer ZIP with `IntuneWinPackage/Contents/IntunePackage.intunewin` and `IntuneWinPackage/Metadata/Detection.xml` | `pytest tests/test_intunewin.py::test_outer_zip_structure` | `tests/test_intunewin.py::test_outer_zip_structure`; `imptune/generators/intunewin_builder.py` outer-ZIP assembly lines 103-111; 01-VERIFICATION.md row 11 | pass | |
| 12 | Encrypted blob uses correct byte layout: HMAC-SHA256 (32 bytes) + IV (16 bytes) + AES-256-CBC ciphertext | `pytest tests/test_intunewin.py::test_encrypted_blob_layout tests/test_intunewin.py::test_iv_is_16_bytes tests/test_intunewin.py::test_hmac_matches` | `tests/test_intunewin.py` (`test_encrypted_blob_layout`, `test_iv_is_16_bytes`, `test_hmac_matches`); `imptune/generators/intunewin_builder.py` (blob = `mac_digest + iv + ciphertext`); 01-VERIFICATION.md row 12 | pass | HMAC-over-IV+ciphertext scope later hardened in commit 74535ea during Phase 10 RTVAL-01 debug — but the byte-layout contract verified here is still the canonical one. |
| 13 | `Detection.xml` contains correct `EncryptionKey`, `MacKey`, `InitializationVector`, `Mac`, `FileDigest` values matching the actual encryption | `pytest tests/test_intunewin.py::test_detection_xml_fields tests/test_intunewin.py::test_decryption_roundtrip tests/test_intunewin.py::test_file_digest_matches tests/test_intunewin.py::test_unencrypted_content_size` | `tests/test_intunewin.py` (5 tests listed); 01-VERIFICATION.md row 13 | pass | Detection.xml field ordering also re-aligned with IntuneWinAppUtil.exe reference format in commit 7716246 (Phase 10 debug); byte-level equivalence preserved. |
| 14 | `.intunewin` output is accepted by a real Microsoft Intune tenant end-to-end (decrypt + app registration) | Dated runtime check recorded in Phase 10 `RUNTIME-VALIDATION.md` (RTVAL-01) | Phase 10 `RUNTIME-VALIDATION.md` RTVAL-01 PASS (2026-04-13, re-test on fixed build after ISSUE-01 resolved via commits 74535ea + 7716246); artifact `.planning/phases/10-real-world-runtime-validation/evidence/Copieur_2eme.intunewin`; STATE.md decision log [Phase 10-01 / 10-02 RTVAL-01 PASS] | pass | Was the single Phase 1 Nyquist gap ("Upload to real Intune tenant" spike in the Manual-Only Verifications table above). Resolved by Phase 10 (NYQ→RTVAL-01) on 2026-04-13; originally would have been `fail-fix-v1.1` → Phase 10 / RTVAL-01, now closed as `pass` citing the Phase 10 sign-off. |
**Audit outcome:** 14/14 rows `pass`. No `fail-fix-v1.1`, `deferred-v1.2`, or `wont-do` rows. Phase 1 is Nyquist-compliant: every success criterion has exactly one observable check with cited, committed evidence.

---
### 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.
