Author: Kyle Bolen <kbolen@amazon.com>
Date:   Tue Jul 28 03:04:05 2026 +0000

    Initial commit: PhotoPhetch v1.0.0
    
    Kotlin/Compose Multiplatform desktop app for importing photos from
    phones into PhotoPhile staging directory.
    
    Features:
    - Android support via ADB subprocess
    - iPhone support via gphoto2 subprocess
    - Smart filtering: excludes screenshots, received images, Live Photo MOVs
    - HEIC -> JPEG conversion via macOS sips (built-in)
    - SHA-256 verification of every copied file
    - Safe delete with explicit confirmation
    - Staging path convention: _staging/{date}_{device}/
    - Config persistence at ~/.photophetch/config.json

+# PhotoPhetch
+
+A macOS desktop app for importing photos from phones into [PhotoPhile](https://git.bolenpad.com/kbolen/photophile)'s staging directory.
+
+Solves the "messy phone import" problem: only grabs camera-roll originals, filters out screenshots and received images, optionally converts HEIC → JPEG, and SHA-256 verifies every file before optionally deleting it from the phone.
+
+## Features
+
+- **Android** support via ADB (`adb pull`)
+- **iPhone** support via gphoto2 (PTP over USB)
+- **Smart filtering**: excludes screenshots, WhatsApp/Telegram received images, and Live Photo motion clips
+- **HEIC → JPEG conversion** via macOS `sips` (built-in, no install needed)
+- **SHA-256 verification** of every copied file
+- **Safe delete**: explicit confirmation screen before removing files from the phone
+- **Staging path convention**: writes to `_staging/<YYYY-MM-DD>_<DeviceName>/`
+- Persists settings to `~/.photophetch/config.json`
+
+## Requirements
+
+- macOS (primary target)
+- Java 21+
+- [Homebrew](https://brew.sh) for dependencies
+
+### Install dependencies
+
+```bash
+# For iPhone support
+brew install gphoto2
+
+# For Android support
+brew install android-platform-tools
+```
+
+## Running
+
+### From source (development)
+
+```bash
+cd photophetch
+./gradlew run
+```
+
+### Build a fat JAR
+
+```bash
+./gradlew packageUberJarForCurrentOS
+# Output: build/compose/jars/photophetch-macos-*.jar
+java -jar build/compose/jars/photophetch-macos-*.jar
+```
+
+### Build a macOS .app bundle
+
+```bash
+./gradlew packageDmg
+# Output: build/compose/binaries/main/dmg/PhotoPhetch-1.0.0.dmg
+```
+
+## First-time setup
+
+1. Launch the app
+2. Go to **Settings** and set your staging root (e.g. `/Volumes/delphi/_staging`)
+3. Make sure your NAS is mounted at that path
+4. Connect your phone via USB
+5. Click **Scan for Devices** on the Connect screen
+
+## iPhone notes
+
+When you plug in an iPhone, macOS's built-in `PTPCamera` daemon may grab the device before gphoto2 can. If PhotoPhetch finds the device but shows no photos:
+
+```bash
+killall PTPCamera
+```
+
+Then rescan in the app.
+
+### HEIC settings
+
+If your iPhone is shooting in HEIC (the default), PhotoPhetch will warn you and convert to JPEG during import. To stop shooting HEIC:
+
+> Settings → Camera → Formats → **Most Compatible**
+
+## Android notes
+
+Enable USB debugging:
+
+> Settings → About Phone → tap Build Number 7 times → Developer Options → USB Debugging
+
+Accept the "Trust this computer?" prompt on the phone when connecting.

+
+## PhotoPhile integration
+
+PhotoPhetch writes directly to the mounted NAS path — no API calls. After import, PhotoPhile picks up the new folder in `_staging/` and runs it through its normal pipeline: configure → normalize → publish.
