Updated code

Blockers:
- IYmtgTests: replace ScannerViewModel() (no-arg init removed) with CollectionViewModel() in testViewModelFiltering and testPortfolioCalculation
- IYmtgTests: fix property access — scannedList, librarySearchText, filteredList, portfolioValue all live on CollectionViewModel, not ScannerViewModel; inject test data after async init settles

Major:
- ContentView: update .onChange(of:) to two-parameter closure syntax (iOS 17 deprecation)
- ModelManager: add missing import FirebaseCore so FirebaseApp.app() resolves explicitly
- CollectionViewModel.deleteCard: call CloudEngine.delete(card:) to remove Firebase entry when a card is deleted (prevents data accumulation)
- CloudEngine: remove never-called batchUpdatePrices() — full backup already handled by backupAllToFirebase()

Minor:
- CardDetailView: move to Features/CardDetail/CardDetailView.swift; remove from ContentView.swift
- Delete PersistenceActor.swift placeholder (superseded by PersistenceController.swift)
- AppConfig.validate(): broaden placeholder-email guard to catch empty strings and common fake domains
- ModelManager: document OTA restart requirement in code comment

-## 3. Machine Learning Training
+---
 
-### **General Data Collection Protocol (CRITICAL)**
+## Part 3: Card Database (`cards.json`) — Mac Required
+
+**This is the most critical file in the project.** The app cannot identify any cards without it. It is a JSON file bundled inside the app containing a fingerprint (a mathematical representation) of every Magic card, generated from card images using Apple's Vision framework.
+
+### What `cards.json` Contains
+Each entry in the file represents one unique card printing and contains:
+- Card name, set code, and collector number
+- Whether the card has a foil or serialized printing
+- Pricing data
+- A `VNFeaturePrintObservation` (binary blob) — the visual fingerprint used for identification
+
+### Step 1: Write `IYmtg_Builder_Mac`
+
+`IYmtg_Builder_Mac/` is currently **empty**. This Mac command-line tool needs to be built before `cards.json` can be generated. It must:
+
+1.  Fetch the complete card list from the Scryfall API (`https://api.scryfall.com/bulk-data` → `default_cards` dataset)
+2.  Download a card image for each unique printing
+3.  Run `VNGenerateImageFeaturePrintRequest` (Apple Vision) on each image to produce a fingerprint
+4.  Archive the fingerprint using `NSKeyedArchiver` into a `Data` blob
+5.  Write all entries to `cards.json` using the `CardFingerprint` model defined in `IYmtg_App_iOS/Data/Models/Card.swift`
+6.  Place the output at `IYmtg_App_iOS/cards.json`
+
+**Data model reference** (`CardFingerprint` in `IYmtg_App_iOS/Data/Models/Card.swift`):
+```swift
+struct CardFingerprint: Codable {
+    let id: UUID
+    let name: String
+    let setCode: String
+    let collectorNumber: String
+    let hasFoilPrinting: Bool
+    let hasSerializedPrinting: Bool?
+    let priceScanned: Double?
+    let featureData: Data   // NSKeyedArchiver-encoded VNFeaturePrintObservation
+}
+```
+
+**To build `IYmtg_Builder_Mac`:** Give this README section to an AI (Claude or Gemini) along with the `CardFingerprint` struct and ask it to write a Swift command-line tool for macOS. The tool is straightforward — it is a single-purpose script that runs once and can take several hours to complete due to the volume of Scryfall image downloads.
+
+### Step 2: Run the Builder
+
+On your Mac, build and run `IYmtg_Builder_Mac`. The `weekly_update.sh` script automates this:
+
+```bash
+chmod +x IYmtg_Automation/weekly_update.sh
+./IYmtg_Automation/weekly_update.sh
+```
+
+This script:
+1.  Builds the builder app using `xcodebuild`
+2.  Runs it (this takes time — Scryfall has ~100,000+ card printings)
+3.  Moves the output `cards.json` into `IYmtg_App_iOS/` ready to be bundled
+
+**Run this script periodically** (e.g., weekly) to pick up newly released sets.
+
+### Step 3: Add `cards.json` to Xcode
+
+After the builder runs, `cards.json` will be at `IYmtg_App_iOS/cards.json`.
+
+In Xcode:
+1.  Drag `cards.json` into the project navigator under `IYmtg_App_iOS/`
+2.  Ensure **"Add to target: IYmtg"** is checked so it is bundled inside the app
+
+---
+
+## Part 4: Xcode Project Setup — Mac Required
+
+The source code in `IYmtg_App_iOS/` is complete. Follow these steps to create the Xcode project on your Mac.
+
+### Step 1: Create the Project
+
+1.  Open Xcode → **File → New → Project**
+2.  Choose **iOS → App**
+3.  Set:
+    - **Product Name:** IYmtg
+    - **Bundle Identifier:** `com.<yourname>.iymtg` (you choose this — note it down, you'll need it for iCloud)
+    - **Interface:** SwiftUI
+    - **Language:** Swift
+    - **Storage:** None (we use SwiftData manually)
+4.  Save the project **inside** `IYmtg_App_iOS/` — this places the `.xcodeproj` alongside the source files.
+
+### Step 2: Add Source Files
+
+1.  In the Xcode project navigator, right-click the `IYmtg` group → **Add Files to "IYmtg"**
+2.  Select all folders inside `IYmtg_App_iOS/`:
+    - `Application/`
+    - `Data/`
+    - `Features/`
+    - `Services/`
+    - `Firebase/`
+    - `AppConfig.swift`
+    - `ContentView.swift`
+    - `IYmtgApp.swift`
+    - `IYmtgTests.swift`
+    - `cards.json` (once generated)
+3.  Ensure **"Copy items if needed"** is **unchecked** (files are already in the right place) and **"Create groups"** is selected.
+
+### Step 3: Add Dependencies (Swift Package Manager)
+
+1.  **File → Add Package Dependencies**
+2.  Add the Firebase iOS SDK:
+    - URL: `https://github.com/firebase/firebase-ios-sdk`
+    - Add these libraries to your target: `FirebaseCore`, `FirebaseFirestore`, `FirebaseAuth`, `FirebaseStorage`
+
+### Step 4: Configure Signing & Capabilities
+
+1.  Select the project in the navigator → **Signing & Capabilities** tab
+2.  Set your **Team** and ensure **Automatically manage signing** is on
+3.  Set **Minimum Deployments** to **iOS 17.0**
+4.  Click **+ Capability** and add:
+    - **iCloud** → enable **CloudKit** → add container `iCloud.<your-bundle-id>`
+    - **Background Modes** → enable **Remote notifications**
+5.  Lock orientation: **General** tab → **Deployment Info** → uncheck Landscape Left and Landscape Right
+
+### Step 5: Add Privacy Descriptions
+
+In `Info.plist`, add these keys (Xcode will prompt on first run, but adding them manually avoids rejection):
+
+| Key | Value |
+| :--- | :--- |
+| `NSCameraUsageDescription` | `IYmtg uses the camera to scan and identify Magic: The Gathering cards.` |
+| `NSPhotoLibraryUsageDescription` | `IYmtg can save card images to your photo library.` |
+
+Also add `PrivacyInfo.xcprivacy` to the app target to satisfy Apple's privacy manifest requirements (required for App Store submission as of 2024).
+
+### Step 6: Build and Run
+
+1.  Select a connected physical iPhone as the build target (camera features do not work in the simulator)
+2.  Press **Cmd+R** to build and run
+3.  On first launch the app will show **"Database Missing"** until `cards.json` is bundled (see Part 3)
+
+---
+
+## Part 5: Machine Learning Training — Mac Required for Final Step
+
+> **In-App Training Guide (v1.1.0+):** The Library tab now includes a "?" button that opens a color-coded Training Guide. It shows every ML category with recommended image counts for three accuracy levels (Functional / Solid / High-Accuracy), so you can track collection progress directly from the app.
+
+**You do not need the app, Xcode, or a Mac to collect training images.** All you need is physical cards and a phone camera. The only Mac-required step is the final model training in Create ML (Step 6).
+
+> **The app ships and works without any trained models.** Foil detection defaults to "None" and condition defaults to "NM". You can release a working app first and add models later via OTA update. Do not let missing training data block your first build.
+
+---
+
+### Step 0: How to Create Training Images (No App Required)
+
+This is the complete workflow for preparing training data on any computer.
+
+#### What You Need
+- Physical Magic cards (see shopping lists in Steps 1–3)
+- A phone with a decent camera (iPhone, Android — anything works)
+- A plain background: white card stock or black felt works best
+- A free photo cropping tool:
+  - **Windows:** Photos app (built-in crop) or Paint
+  - **Any platform:** [Squoosh](https://squoosh.app) (browser-based, free, no install)
+  - **Bulk cropping:** [IrfanView](https://www.irfanview.com) (Windows, free) or [XnConvert](https://www.xnview.com/en/xnconvert/) (cross-platform, free)
+
+#### Photography Setup
+
+**For Foil Cards:**
+1. Place the card on a **black background** (black felt or black paper).
+2. Use a single directional light source — a desk lamp or window at 45°.
+3. Take **5 photos of the same card** rotating it slightly between each shot so the light catches the foil at different angles. The AI must learn how the foil *moves*, not just how it looks flat.
+4. Example angles: flat-on, 15° left tilt, 15° right tilt, 15° top tilt, 15° bottom tilt.
+
+**For Non-Foil Cards:**
+1. Place on **white or grey background**.
+2. Even, diffused lighting (avoid strong reflections on the surface).
+3. 1–3 photos per card is sufficient.
+
+**For Condition/Damage:**
+1. Use **raking light** (light source almost parallel to the card surface) — this casts shadows that highlight scratches, dents, and bends far more clearly than direct light.
+2. For edge whitening: photograph against a **black background**.
+3. For chipping: photograph against a **white background**.
+4. Take a close-up — fill the frame with the card.
+
+#### Cropping Rule — Critical
+The app scans **cropped card images only** (no table, no background, no hand visible). Your training images must match this exactly or the model will learn the wrong thing.
+
+After photographing:
+1. Open the photo in your cropping tool.
+2. Crop tightly to the card border — include the full card frame but nothing outside it.
+3. It does not need to be pixel-perfect. Within 5–10px of the edge is fine.
+4. Save as `.jpg` at any reasonable resolution (at least 400×560px).
+
+#### Naming and Sorting
+File names do not matter — only the **folder** they are in matters. Save cropped images directly into the appropriate `IYmtg_Training/` subfolder:
+
+```
+IYmtg_Training/Foil_Data/Etched/   ← drop etched foil photos here
+IYmtg_Training/Foil_Data/Traditional/  ← drop traditional foil photos here
+IYmtg_Training/Condition_Data/Edges/Whitening/  ← drop edge whitening photos here
+```
+
+#### How Many Images Do You Need?
+| Goal | Minimum | Recommended |
+| :--- | :--- | :--- |
+| Test that training works | 10 per class | — |
+| Functional model, limited accuracy | 20 per class | — |
+| Solid production model | 30–50 per class | 50+ per class |
+| High-accuracy model | — | 100+ per class |
+
+More is always better. Variety matters more than quantity — different cards, different lighting, different tilt angles.
+
+#### Using Scryfall Images as a Supplement
+For **NonFoil** training data you can download card images directly from Scryfall instead of photographing them. This is automated — run:
+
+```bash
+pip install requests pillow
+python3 IYmtg_Automation/fetch_set_symbols.py
+```
+
+This downloads and crops set symbol images automatically. For general NonFoil card images, you can query the Scryfall API directly (`https://api.scryfall.com/cards/random`) and download the `normal` image URI. Downloaded Scryfall images are already cropped to the card frame and work well as NonFoil training data. Do not use Scryfall images for foil or damage training — they are flat renders with no foil or physical damage.

+---

 ### Step 3: The "Damage Simulation Lab"
-Techniques to ethically create training data using "Draft Chaff" (worthless cards).
 
-| Category | Damage Type | Simulation Technique | Capture Tip (Crucial for ML) |
+#### Important: This Model Uses Object Detection, Not Image Classification
-| :--- | :--- | :--- | :--- |
+
-| **Surface** | Light Scratches | Rub foil surface gently with 0000 Steel Wool. | Use flash or moving light source to catch glint. |
+The `Condition_Data` model is trained as an **Object Detection** model, not an Image Classification model. This is a critical difference:
-| **Surface** | Clouding | Rub white eraser vigorously over foil surface. | Compare side-by-side with a clean card. |
+
-| **Surface** | Dirt | Smudge lightly with potting soil or cocoa powder. | Ensure contrast against card art. |
+- **Image Classification** (used for Foil and Stamp): drop images in a folder, Create ML labels them by folder name. Simple.
-| **Surface** | Dents | Press a ballpoint pen cap firmly into the surface. | **Raking Light:** Light from side to cast shadows. |
+- **Object Detection** (used for Condition): you must **draw bounding boxes** around each defect in Create ML. The model learns *where* damage is on the card, not just that damage exists.
-| **Edges** | Whitening | Rub card edges rapidly against denim jeans. | Photograph against a **Black Background**. |
+
-| **Edges** | Chipping | Flake off small bits of black border. | Photograph against a **White Background**. |
+When training in Create ML, you will annotate each training image by drawing a rectangle around the damaged area and labeling it (e.g., "LightScratches", "Whitening"). Create ML has a built-in annotation tool — click an image, draw a box, type the label.
-| **Edges** | Corner Wear | Rub corners against a rough mousepad. | Macro focus on the corner radius. |
+
-| **Structure** | Creases | Fold a corner until a hard line forms. | Catch the light reflection off the crease ridge. |
+**Folder naming maps directly to label names.** The labels must match the `Condition_Data` subfolder names exactly:
-| **Structure** | Shuffle Bend | Riffle shuffle aggressively to create an arch. | Profile view (side view) to show curvature. |
+`LightScratches`, `Clouding`, `Dirt`, `Dents`, `Whitening`, `Chipping`, `CornerWear`, `Creases`, `ShuffleBend`, `WaterDamage`, `Inking`, `Rips`, `BindersDents`
-| **Structure** | Water Damage | Mist with spray bottle, wait 60s, dry. | Catch the rippled surface texture with side light. |
+
-| **Critical** | Inking | Use a Black Sharpie to "fix" whitened edges. | Use UV/Blacklight if possible, or bright white light. |
+#### How the Grading Formula Works
-| **Critical** | Rips | Tear the edge slightly (approx. 5mm). | High contrast background. |
+
-| **Critical** | Binders Dents | Press a 3-ring binder ring into the card. | Raking light to show the circular crimp. |
+Understanding this helps you know what training data matters most. The app grades cards as follows (from `ConditionEngine.swift`):
+
+| Detected Damage | Grade Assigned |
+| :--- | :--- |
+| Any `Inking`, `Rips`, or `WaterDamage` detected | **Damaged** — immediately, regardless of anything else |
+| 0 damage detections | **Near Mint (NM)** |
+| 1–2 minor damage detections | **Excellent (EX)** |
+| 3 or more minor damage detections | **Played (PL)** |
+
+**Critical damage types** (`Inking`, `Rips`, `WaterDamage`) are the highest training priority — a single false positive will incorrectly grade a NM card as Damaged.
+
+#### Materials List
+
+| Item | Used For |
+| :--- | :--- |
+| 0000 (ultra-fine) steel wool | Surface scratches on foil cards |
+| White vinyl eraser | Clouding/surface haze |
+| Potting soil or cocoa powder | Dirt simulation |
+| Ballpoint pen cap (rounded end) | Dents |
+| Black Sharpie marker | Inking simulation |
+| Spray bottle with water | Water damage |
+| 3-ring binder | Binder dents |
+| Rough mousepad or sandpaper | Corner wear |
+| 50–100 bulk "draft chaff" cards | Cards to damage |
+| Black felt or black paper | Background for edge photos |
+| White card stock | Background for chipping photos |
+| Desk lamp | Raking light source |
+
+#### Sourcing Cards to Damage
+
+Buy bulk worthless cards — do not damage your own collection.
+- **eBay:** Search "MTG bulk commons lot" — 1000 cards for ~$10
+- **TCGPlayer:** "Bulk commons" listings, often $0.01/card
+- **Local game store:** Ask for "draft chaff" — often given away free
+
+Also buy **pre-damaged cards** — natural damage looks more authentic to the model than simulated:
+- **eBay:** Search "MTG damaged cards lot" or "heavily played bulk"
+
+Aim for **50 cards per damage type** minimum. One card can be used for multiple damage types since each photo annotates only one damage area.
+
+#### Raking Light Setup (Required for Surface and Structure Damage)
+
+Most damage is invisible under flat overhead light. Raking light reveals it.
+
+1. Place the card flat on a dark surface.
+2. Position your desk lamp so light hits the card at a near-horizontal angle (5–15° above the surface) from one side.
+3. The damage will cast visible shadows or catch the light clearly.
+4. For scratches: slowly rotate the card until the scratches "light up" — photograph at that angle.
+
+#### Damage Simulation Techniques
+
+| Category | Damage Type | Folder Name | Simulation Technique | Photography Tip |
+| :--- | :--- | :--- | :--- | :--- |
+| **Surface** | Light Scratches | `LightScratches` | Rub foil surface gently with 0000 Steel Wool in one direction. | Raking light from the scratched direction. Rotate until scratches catch light. |

+
+For each damage type, capture:

+2. **10–20 completely clean (undamaged) cards** — include these in every subfolder so the model learns the baseline
+
+When annotating in Create ML, draw the bounding box **tightly around the damaged area only**. For shuffle bends, annotate the center of the arch. For edge damage, annotate the specific section of edge that is damaged, not the entire edge.

+
+---
+
+## Part 6: Community Feedback & Model Retraining
+
+The app has a built-in pipeline that collects user corrections and uses them to improve the ML models over time. This section explains how it works end-to-end.
+
+### How the Feedback System Works
+
+There are two data collection paths:
+
+**Path 1 — User Corrections (Community Data)**
+When a user corrects a mis-scan (wrong card identity, wrong foil type, or wrong condition), the app automatically uploads the cropped card image to Firebase Storage — but only if the user has opted in.
+
+The upload destination is determined by what was corrected:
+
+| What Changed | Firebase Storage Path | Used to Retrain |
+| :--- | :--- | :--- |
+| Card name or set | `training/Identity_<SETCODE>_<CollectorNum>/` | `cards.json` (re-fingerprint) |
+| Foil type | `training/Foil_<FoilType>/` | `IYmtgFoilClassifier.mlmodel` |
+| Condition grade | `training/Condition_<Grade>/` | `IYmtgConditionClassifier.mlmodel` |
+
+Example: A user corrects a card that was identified as "Traditional" foil to "Etched". The image is uploaded to `training/Foil_Etched/<UUID>.jpg`.
+
+**Path 2 — Dev Mode (Your Own Device)**
+When the `ENABLE_DEV_MODE` build flag is active and you tap the logo header 5 times, every raw scan frame is saved locally to `Documents/RawTrainingData/` on the device. Sync this folder to your Mac via Xcode's Devices window or Files app to retrieve images.
+
+### User Opt-In
+
+Users must explicitly opt in before any images are uploaded. The opt-in state is stored in `AppConfig.isTrainingOptIn` (backed by `UserDefaults`).
+
+You must expose a toggle in your app's Settings/Library UI that sets `AppConfig.isTrainingOptIn = true/false`. The app description mentions this as the "Community Data Initiative" — users are told their corrections improve the AI for everyone.
+
+**Firebase Authentication note:** `TrainingUploader` only uploads when `FirebaseApp.app() != nil` — meaning Firebase must be configured (`GoogleService-Info.plist` present) for community uploads to work. The app functions without Firebase, but no feedback is collected in that mode.
+
+### Firebase Storage Rules
+
+The rules in `IYmtg_App_iOS/Firebase/storage.rules` enforce:
+- `training/` — authenticated users can **write only** (upload corrections). No user can read others' images.
+- `models/` — anyone can **read** (required for OTA model downloads). Write access is developer-only via the Firebase Console.
+
+### Downloading Collected Training Data
+
+1.  Go to the **Firebase Console → Storage → training/**
+2.  You will see folders named by label (e.g., `Foil_Etched/`, `Condition_Near Mint (NM)/`)
+3.  Download all images in each folder — use the Firebase CLI for bulk downloads:
+    ```bash
+    # Install Firebase CLI if needed
+    npm install -g firebase-tools
+    firebase login
+
+    # Download all training data
+    firebase storage:cp gs://<your-bucket>/training ./downloaded_training --recursive
+    ```
+4.  You now have a folder of user-contributed cropped card images, organized by label.
+
+### Reviewing and Sorting Downloaded Images
+
+**Do not skip this step.** User uploads can include blurry photos, wrong cards, or bad crops. Review each image before adding it to your training set.
+
+1.  Open each label folder from the download.
+2.  Delete any images that are: blurry, poorly cropped, show background, or are clearly wrong.
+3.  Move the accepted images into the corresponding `IYmtg_Training/` subfolder:
+
+| Downloaded Folder | Move to Training Folder |
+| :--- | :--- |
+| `Foil_Traditional/` | `IYmtg_Training/Foil_Data/Traditional/` |
+| `Foil_Etched/` | `IYmtg_Training/Foil_Data/Etched/` |
+| `Foil_<Type>/` | `IYmtg_Training/Foil_Data/<Type>/` |
+| `Condition_<Grade>/` | Inspect condition grade — map to `Condition_Data/` subfolder by damage type visible |
+
+> **Identity corrections** (`training/Identity_*/`) are not used to retrain ML models. They indicate that the visual fingerprint for that card may be wrong or ambiguous. Review these separately and consider re-running the Builder for those specific cards.
+
+### Retraining the Models
+
+Once you have added new images to `IYmtg_Training/`:
+
+1.  Open **Create ML** on your Mac.
+2.  Open your existing project for the model you want to update (e.g., `IYmtgFoilClassifier`).
+3.  The new images in the training folders will be picked up automatically.
+4.  Click **Train**. Create ML will train incrementally on the expanded dataset.
+5.  Evaluate the results — check accuracy on the **Validation** tab. Aim for >90% accuracy before shipping.
+6.  Export the updated `.mlmodel` file.
+
+### Pushing the Updated Model via OTA
+
+You do not need an App Store update to ship a new model version. Use Firebase Storage:
+
+1.  In the **Firebase Console → Storage**, navigate to the `models/` folder.
+2.  Upload your new `.mlmodel` file with the **exact same filename** (e.g., `IYmtgFoilClassifier.mlmodel`).
+3.  On the next app launch, `ModelManager` detects the newer version, downloads and compiles it, and swaps it in automatically.
+
+> **Important:** The new model takes effect on the **next app launch after download**, not immediately. Users may need to relaunch once.
+
+### Recommended Retraining Schedule
+
+| Trigger | Action |
+| :--- | :--- |
+| 50+ new correction images accumulated | Review, sort, retrain affected model, push OTA |
+| New MTG set released with new foil type | Add training folder, acquire cards, retrain FoilClassifier |
+| New MTG set released | Rebuild `cards.json` via `weekly_update.sh` |
+| Significant accuracy complaints from users | Download corrections, review, retrain |
+
+---
+
+## Part 7: Backend & Security
+
+### Cloud Storage Architecture
+The app uses a two-tier cloud strategy:
+
+| Tier | Technology | What it stores | Cost |
+| :--- | :--- | :--- | :--- |
+| **Primary** | iCloud + CloudKit (SwiftData) | All card metadata, synced automatically across devices | Free (user's iCloud) |
+| **Secondary** | Firebase Firestore | Metadata only — no images — optional manual backup | Free (Firestore free tier) |
+
+Card images are stored in the user's iCloud Drive under `Documents/UserContent/` and are **never** uploaded to Firebase.
+
+### iCloud / CloudKit Setup (Required for Primary Sync)
+1.  In Xcode, open **Signing & Capabilities**.
+2.  Add the **iCloud** capability. Enable **CloudKit**.
+3.  Add a CloudKit container named `iCloud.<your-bundle-id>`.
+4.  Add the **Background Modes** capability. Enable **Remote notifications**.
+5.  Set the minimum deployment target to **iOS 17** (required by SwiftData).
+
+Without this setup the app falls back to local-only storage automatically.
+
+### Firebase Configuration (Optional Secondary Backup)
+Firebase is no longer the primary sync mechanism. It serves as a user-triggered metadata backup.
 1.  **Create Project:** Go to the Firebase Console and create a new project.
 2.  **Authentication:** Enable "Anonymous" sign-in in the Authentication tab.
 3.  **Firestore Database:** Create a database and apply the rules from `IYmtg_App_iOS/Firebase/firestore.rules`.
-4.  **Storage:** Enable Storage and apply the rules from `IYmtg_App_iOS/Firebase/storage.rules`.

-5.  **Setup:** Download `GoogleService-Info.plist` from Project Settings and drag it into the `IYmtg_App_iOS` folder in Xcode (ensure "Copy items if needed" is checked).
+5.  Users trigger backup manually via **Library → Cloud Backup → Backup Metadata to Firebase Now**.
+
+The app runs fully without `GoogleService-Info.plist` (Local Mode — iCloud sync still works).

+# AI Blueprint: Full Project Readiness Audit
+
+## Goal
+
+To perform a comprehensive audit of the `IYmtg_App_iOS` project to ensure it can be compiled without errors and to identify any missing or incomplete features before handing it off to a human developer.
+
+## Audit Steps for Claude
+
+1.  **Dependency Verification:**
+    *   Review the project's dependencies. Since this is a Swift project, check for any package manager configurations (like Swift Package Manager, CocoaPods, or Carthage). If any are found, ensure all required dependencies are listed and correctly configured.
+    *   Verify that all required versions of dependencies are compatible with the project's Swift version.
+
+2.  **File and Resource Integrity Check:**
+    *   Scan the project for any missing files or broken links. Pay close attention to assets, storyboards, and any other resources referenced in the code.
+    *   Ensure all necessary `.swift` files are included in the build targets.
+
+3.  **Static Code Analysis:**
+    *   Perform a static analysis of the entire Swift codebase in `IYmtg_App_iOS/`.
+    *   Look for common compilation issues such as:
+        *   Syntax errors.
+        *   Type mismatches.
+        *   Unresolved identifiers (e.g., variables or functions that are used but not defined).
+        *   Incorrect use of optionals.
+        *   API deprecation warnings.
+
+4.  **Feature Completeness Review:**
+    *   Examine the code for any features that are stubbed out, marked with `// TODO:`, `// FIXME:`, or are otherwise incomplete.
+    *   Pay special attention to the `Features` directory (`IYmtg_App_iOS/Features/`) to assess the state of each feature (CardDetail, Collection, Help, Scanner).
+    *   Check for any disabled or commented-out code that might indicate an incomplete feature.
+
+5.  **Audit Summary Report:**
+    *   Create a summary of all findings in a new file named `claude_review_summary.md`.
+    *   For each issue, provide a description, the file path, and the relevant line number(s).
+    *   Categorize the issues by severity (e.g., Blocker, Critical, Major, Minor).
+
+6.  **Update README.md:**
+    *   Add a new section to the `README.md` file titled "Project Audit".
+    *   Under this section, add a brief summary of the audit's outcome and a link to the `claude_review_summary.md` file.
+
+7.  **Create Git Commit:**
+    *   Stage all the changes (the new `claude_review_summary.md` and the updated `README.md`).
+    *   Create a Git commit with the message: "feat: Complete project readiness audit".
+
+8.  **Increment Project Version:**
+    *   If the audit reveals significant issues that require code changes, increment the project's build number. If no significant issues are found, this step can be skipped. The location of the version number is likely in the project's settings or an `Info.plist` file.

+# Architect AI Instructions
+
+This document contains the instructions for the Architect AI (Roo).
+
+## My Role
+
+My primary role is to act as a technical planner and architect. I do not write implementation code. My goal is to understand the user's request, analyze the existing codebase, and produce a clear, step-by-step plan for another AI (Claude) to execute.
+
+## My Process
+
+1.  **Information Gathering:** I will use the available tools to explore the codebase and gather context relevant to the user's request. This includes reading files, searching for code, and listing files.
+2.  **Clarification:** If the user's request is ambiguous, I will ask clarifying questions to ensure I have all the necessary details before creating a plan.
+3.  **Planning:** I will create a detailed, step-by-step plan. This plan will be written to the `ai_blueprint.md` file, and will overwrite the file if it already exists.
+4.  **Plan Contents:** Each plan I create in `ai_blueprint.md` must include:
+    *   A high-level overview of the goal.
+    *   A sequential list of tasks for the implementation AI.
+    *   Specific file paths that need to be created or modified.
+    *   High-level descriptions of the changes required.
+    *   A mandatory step to update the `README.md` if necessary.
+    *   A mandatory step to create a Git commit with a descriptive message.
+    *   A mandatory step to increment the project version number.
+5.  **No Coding:** I will not write or modify any code files (e.g., `.swift`, `.py`, `.js`). My modifications are restricted to markdown files (`.md`). Providing code snippets within markdown files is acceptable for planning purposes, but I will not directly execute or create code files.
+6.  **Handoff:** Once the plan is written to `ai_blueprint.md`, my task is complete. I will inform the user that the plan is ready for the implementation phase.

+# Claude Review Summary
+**Review Date:** 2026-03-05 (Revision 2 — Full Compilation Readiness Audit)
+**Blueprint:** `ai_blueprint.md` — Full Project Readiness Audit
+
+---
+
+## Executive Summary
+
+The source code is architecturally complete and well-structured. Two **Blocker** issues will prevent the test target from compiling. One **Critical** issue (missing `cards.json` generator) means the scanner cannot function at all at runtime. Four **Major** issues represent deprecation warnings and a Firebase data-leak bug. The app target itself will compile once Firebase imports are confirmed.
+
+---
+
+## 1. Dependency Verification
+
+### Package Manager
+No `Package.swift`, `Podfile`, or `Cartfile` exists in the repository. Swift Package Manager dependencies are managed through the Xcode `.xcodeproj` file, which lives on the developer's Mac (not in this repo). Dependency versions cannot be verified from source alone.
+
+**Required SPM packages (must be added in Xcode):**
+
+| Package | Required Modules | Min Version |
+|---|---|---|
+| `firebase-ios-sdk` | FirebaseCore, FirebaseAuth, FirebaseFirestore, FirebaseStorage | ≥ 10.x |
+| SwiftData | Built-in (iOS 17+) | iOS 17 SDK |
+
+**Minimum Deployment Target:** iOS 17 is required by `SwiftData`, `@ModelActor`, and `ModelContainer`. This must be set in Xcode → Build Settings.
+
+---
+
+## 2. File & Resource Integrity
+
+### Missing Runtime Files (excluded by `.gitignore` — must be added before shipping)
+
+| File | Referenced In | Status |
+|---|---|---|
+| `cards.json` | `ScannerViewModel.swift:96` | ❌ **CRITICAL** — Generator (`IYmtg_Builder_Mac/`) is empty |
+| `GoogleService-Info.plist` | `IYmtgApp.swift:9` | ⚠️ Expected missing — handled gracefully with local-mode fallback |
+| `IYmtgFoilClassifier.mlmodel` | `FoilEngine.swift:12` | ⚠️ Expected missing — app degrades gracefully (foil = "None") |
+| `IYmtgConditionClassifier.mlmodel` | `ConditionEngine.swift:17` | ⚠️ Expected missing — app degrades gracefully (grade = "Ungraded") |
+| `IYmtgStampClassifier.mlmodel` | `StampDetector.swift:8` | ⚠️ Expected missing — app degrades gracefully |
+| `IYmtgSetClassifier.mlmodel` | `SetSymbolEngine.swift:8` | ⚠️ Expected missing — app degrades gracefully |
+
+### Missing Image Assets (must exist in `Assets.xcassets` inside Xcode project)
+
+| Asset Name | Referenced In | Notes |
+|---|---|---|
+| `scanner_frame` | `ContentView.swift:114` | Required — scanner overlay frame |
+| `logo_header` | `ContentView.swift:147` | Required — header logo |
+| `empty_library` | `ContentView.swift:230` | Required — empty state illustration |
+| `share_watermark` | `ContentView.swift:334` | Optional — has fallback text if missing |
+
+### Placeholder / Orphan Files
+
+| File | Issue |
+|---|---|
+| `Data/Persistence/PersistenceActor.swift` | Empty placeholder — must be **removed from Xcode project navigator** (note inside the file confirms this) |
+| `Features/CardDetail/` | Directory is empty — `CardDetailView` is defined in `ContentView.swift` instead |

+
+## 3. Static Code Analysis
+
+### BLOCKER Issues (prevent compilation)
+
+#### B1 — `IYmtgTests.swift:113` — `ScannerViewModel()` no-arg init does not exist
+**Severity:** Blocker | **File:** `IYmtg_App_iOS/IYmtgTests.swift` | **Lines:** 113, 137
+
+`ScannerViewModel` only exposes `init(collectionVM: CollectionViewModel)`. The test file calls `ScannerViewModel()` with no arguments in two test functions (`testViewModelFiltering` and `testPortfolioCalculation`). The Swift compiler will reject this.
+
+```swift
+// Current (BROKEN):
+let vm = ScannerViewModel()
+
+// Fix:
+let colVM = CollectionViewModel()
+let vm = ScannerViewModel(collectionVM: colVM)
+```
+
+#### B2 — `IYmtgTests.swift:118-148` — Accessing non-existent properties on `ScannerViewModel`
+**Severity:** Blocker | **File:** `IYmtg_App_iOS/IYmtgTests.swift` | **Lines:** 118, 121, 126, 137, 143
+
+The test directly assigns/reads `vm.scannedList`, `vm.librarySearchText`, `vm.filteredList`, and `vm.portfolioValue` on a `ScannerViewModel` instance. None of these are forwarded computed properties on `ScannerViewModel` — they belong to `CollectionViewModel`. The compiler will produce unresolved identifier errors.
+
+**Fix:** Obtain these properties from `vm.collectionVM` instead:
+```swift
+vm.collectionVM.scannedList = [card1, card2]
+vm.collectionVM.librarySearchText = "Alpha"
+// etc.
+```

+
+### CRITICAL Issues (app non-functional at runtime)
+
+#### C1 — `cards.json` generator is missing (`IYmtg_Builder_Mac/` is empty)
+**Severity:** Critical | **File:** `IYmtg_Builder_Mac/` (directory) | **Line:** N/A
+
+`ScannerViewModel.init` attempts to load `cards.json` from the app bundle. If absent, the app immediately shows a "Database Missing" alert and the scanner is permanently non-functional. The `IYmtg_Builder_Mac/` directory — which should contain the Swift CLI tool that generates this file — is completely empty. This is the single most important missing piece before any developer can test the scanner.
+
+---
+
+### MAJOR Issues (warnings or significant functional gaps)
+
+#### M1 — Deprecated `.onChange(of:)` API (iOS 17 deprecation warnings)
+**Severity:** Major | **File:** `IYmtg_App_iOS/ContentView.swift` | **Lines:** 172, 237
+
+The single-parameter closure form of `.onChange(of:)` was deprecated in iOS 17. Since the app targets iOS 17+, Xcode will emit deprecation warnings on every build.
+
+```swift
+// Line 172 — DEPRECATED:
+.onChange(of: scenePhase) { newPhase in ... }
+
+// Fix:
+.onChange(of: scenePhase) { _, newPhase in ... }
+
+// Line 237 — DEPRECATED:
+.onChange(of: vm.selectedCurrency) { _ in vm.refreshPrices(force: true) }
+
+// Fix:
+.onChange(of: vm.selectedCurrency) { _, _ in vm.refreshPrices(force: true) }
+```
+
+#### M2 — `ModelManager.swift` missing `import FirebaseCore`
+**Severity:** Major | **File:** `IYmtg_App_iOS/Services/CoreML/ModelManager.swift` | **Lines:** 1–3, 35
+
+`ModelManager.swift` uses `FirebaseApp.app()` (a `FirebaseCore` type) but only imports `FirebaseStorage`. In Swift, each file must explicitly import the module it uses. This may compile in some Xcode/SPM configurations where `FirebaseStorage` transitively links `FirebaseCore`, but it is not guaranteed and should be made explicit.
+
+```swift
+// Add to ModelManager.swift imports:
+import FirebaseCore
+```
+
+#### M3 — `CloudEngine.delete(card:)` never called — Firebase data leak on card deletion
+**Severity:** Major | **File:** `IYmtg_App_iOS/Features/Collection/CollectionViewModel.swift` | **Line:** 271–278
+
+`CollectionViewModel.deleteCard(_:)` removes the card from SwiftData (via `saveCollectionAsync()`) and deletes the local image, but never calls `CloudEngine.delete(card:)`. Any cards that were previously backed up to Firebase Firestore will remain in the user's Firestore inventory forever after deletion. The method to fix this already exists — it just needs to be called.
+
+```swift
+// In CollectionViewModel.deleteCard(_:), after removing from scannedList:
+Task { await CloudEngine.delete(card: card) }
+```
+
+#### M4 — `CloudEngine.batchUpdatePrices()` is dead code
+**Severity:** Major | **File:** `IYmtg_App_iOS/Services/Cloud/CloudEngine.swift` | **Lines:** 49–69
+
+`CloudEngine.batchUpdatePrices(cards:)` is fully implemented but never called anywhere in the codebase. Price updates are reflected in SwiftData + CloudKit automatically, making this function either redundant or an incomplete feature. It should either be wired into the price-refresh flow or removed.
+
+---
+
+### MINOR Issues (low impact, housekeeping)
+
+#### m1 — `Features/CardDetail/` directory is empty
+**Severity:** Minor | **File:** `IYmtg_App_iOS/Features/CardDetail/` (directory)
+
+`CardDetailView`, `DashboardView`, `ScannerView`, `WelcomeView`, and `FeatureRow` are all defined in `ContentView.swift`, making it a 469-line monolith. The `CardDetail/` directory exists but holds no files. This violates the project's modular structure intent but does not affect compilation.
+
+#### m2 — `PersistenceActor.swift` placeholder in Xcode project
+**Severity:** Minor | **File:** `IYmtg_App_iOS/Data/Persistence/PersistenceActor.swift`
+
+This file contains only a migration comment and no executable code. It must be manually removed from the Xcode project navigator to avoid confusion (the file itself documents this).
+
+#### m3 — `AppConfig.swift` not configured for production
+**Severity:** Minor | **File:** `IYmtg_App_iOS/AppConfig.swift` | **Lines:** 24, 27
+
+| Setting | Current Value | Required |
+|---|---|---|
+| `contactEmail` | `"support@iymtg.com"` | Real developer email (Scryfall policy) |
+| `tipJarProductIDs` | `[]` | Real App Store Connect product IDs |
+| `buildNumber` | `"2"` | Increment with each App Store submission |
+
+The `validate()` function checks for `"yourdomain.com"` but not for `"iymtg.com"`, so the fatalError guard will not fire in DEBUG with the current placeholder.
+
+#### m4 — OTA model updates require app restart (undocumented)
+**Severity:** Minor | **File:** `IYmtg_App_iOS/Services/CoreML/ModelManager.swift` | **Line:** 16
+
+`FoilEngine.model`, `ConditionEngine.model`, `StampDetector.model`, and `SetSymbolEngine.model` are all `static var` properties evaluated once at class-load time. When `ModelManager.checkForUpdates()` downloads a new `.mlmodelc` to Documents, the running app will not use it until restarted. This is expected behavior but should be documented in the README or in-app release notes.
