- Settings STARTUP MODE chips (AsyncStorage startup_mode): default = clean camera
+ PROVIA neutral 4:3, last = restore full session look.
- initSession: resolve sim-* recipe ids via FILM_SIMS (fix clobber of session
ratio/adjustments to 4:3 canonical); restore via setSelectedRecipe not
applyRecipe so user tweaks (frame/geotag/ratio) survive restore.
- applyDefaultStartup turns GPS watermark OFF (user-requested default).
- Shutter: OFF must not play click on must-play-policy devices. VisionCamera
v5.2.3 HybridPhotoOutput.kt plays MediaActionSound itself gated by
(enableShutterSound ?: true) || mustPlayShutterSound — on Xiaomi mustPlay=true
so OFF still clicked. Both capture paths now gate on enableShutterSound != false.
node_modules patch not trackable -> artifacts/patches/vision-camera-shutter-silent.patch.
Verified on Xiaomi 12S Ultra: log SND user=false -> play=false; cold-start
DEFAULT shows GPS WATERMARK OFF.
Local Kotlin module modules/recipescam-export (autolinked via expo ./modules)
exposes decodeEncodeAsync — BitmapFactory decode -> JPEG q95 encode -> file,
all on Dispatchers.IO off the JS/main threads. EXPO_PUBLIC_BENCH=1 builds run
src/dev/nativeBenchProbe.ts: 3 timed decode+encode passes on the bundled
wallframe artwork plus a JS-timer gap check proving the JS thread never
blocks during native rendering. Legacy Skia engine untouched (reference).
Lightroom-style 'Screen' output sharpen (unsharp mask, 3x3 convolution
via Skia ImageFilter.MakeMatrixConvolution, amount 0.5, kernel sums to
1) applied to final pixels before JPEG encode. Camera-capture branch
passes { dpi: 300, sharpen: true }; library-mode export untouched.
Export pixels were already full resolution - sharpen is a new final
GPU pass, no pixel-count change.
Skia JPEG re-encode drops original header (72dpi camera default). New
src/utils/jpegDpi.ts rewrites JFIF APP0 density + EXIF X/YResolution
(endian-aware) or inserts minimal JFIF when neither exists; applied via
processAndExportPhoto options.dpi in the camera-capture branch only.
Library-mode exports untouched. Pixels never change - metadata only.
