All videos therefore survived the poison pill -- a serious data-leak that defeats the feature's purpose. Add deleteNonDecoyVideos(), invoked before deleteNonDecoyImages() (which removes the decoy directory used for the decoy check). A video is preserved only if a file with the same name exists in the decoy directory; since decoy selection is photo-only today, every video is destroyed -- while remaining forward-compatible if video decoys are added later. Tests: PoisonPillVideoDeletionTests covers both the destroy and decoy-preserve paths. To make them run, the previously orphaned FakeEncryptionScheme / FakeThumbnailCache test helpers were added to the SnapSafeTests target (and FakeEncryptionScheme updated to match the current EncryptionScheme protocol).

Removed (obsolete/superseded - tested types that no longer exist): - SecureFileManagerTests, EditedPhotoTrackingTests (SecureFileManager removed) - LocationManagerTests (replaced by LocationRepository) - PINManagerTests (replaced by PinRepository/PinCrypto) - SecurePhotoTests (SecurePhoto model removed) - CameraModelTests (CameraModel renamed to CameraViewModel) - CameraLifecycleTests (CameraViewModel.isSessionActive removed) - FaceDetectorTests (MaskMode reduced to .pixelate; blurFaces removed) - PhotoDetailViewModelTests (built on removed SecurePhoto + showFaceDetection) - SnapSafeTests (empty Xcode template stub) Folded into the target (valid tests of current code, with minor fixes): - VerifyPinUseCaseTests - updated to current AuthorizePinUseCase / VerifyPinUseCase initializers; import FactoryKit; @MainActor. - SECVFileFormatTests - UInt32 conversions; fileLength: label. - SecureImageRepositoryTests - drop removed getPhotoByName tests; saveImage now takes CLLocation; add getVideosDirectory override for isolation. - Added the previously-orphaned FakeEncryptionScheme / FakeThumbnailCache helpers to the target. Full unit suite now compiles and runs: 92 passed, 0 failed (was 58).

Even preserving a video as-is would be broken, since activatePoisonPill deletes the real key's DEK, making real-key content undecryptable. Mirror the photo decoy model for videos: - VideoEncryptionService: add encryptVideoForDecoy(...) async (awaitable encrypt). - SecureImageRepository: inject VideoEncryptionService; add isDecoyVideo, addDecoyVideoWithKey (decrypt with current key -> re-encrypt with poison-pill key into the decoy dir), removeDecoyVideo; count videos toward the shared decoy limit. deleteNonDecoyVideos now destroys non-decoy videos AND moves each decoy's poison-pill-key copy into the videos dir, replacing the real-key original (runs before deleteNonDecoyImages, which removes the decoy dir). - AddDecoyVideoUseCase + DI wiring (and pass VideoEncryptionService into the SecureImageRepository factory). - MixedMediaGalleryViewModel: saveDecoySelections add/remove decoy videos; decoy count, pre-selection, and strings now include videos. Result: decoy videos are re-encrypted with the poison-pill key and remain playable under the duress PIN; all non-decoy videos are destroyed. Tests (PoisonPillVideoDeletionTests, + FakeVideoEncryptionService): - non-decoy videos destroyed (decoy photo preserved) - addDecoyVideoWithKey re-encrypts and marks the video a decoy - end-to-end: mark decoy video -> poison pill -> decoy file replaced by the poison-pill-key copy, non-decoy video destroyed Full unit suite: 93 passed, 0 failed.

Previously the decoy gallery dismissed immediately and the work ran detached, giving the user no feedback. - saveDecoySelections() is now async and drives isSavingDecoys + a completed/total counter (only items whose decoy state changes are processed). - SecureGalleryView awaits the save and dismisses only when it completes, showing a dimmed spinner overlay ("Saving decoy media…" with an N-of-M count for multiple items). Save/Back are disabled while saving. Note: the SECV re-encryption still runs on the main actor (the VideoEncryptionService is @MainActor). The indeterminate ProgressView animates on the render server so the spinner stays alive, but the rest of the UI is blocked during the crypto. Moving the crypto off the main actor is a follow-up; the recording path already consumes its progress via receive(on: .main), so it should be feasible.

Now each video has a real thumbnail. Because videos are encrypted SECV (unreadable by AVAssetImageGenerator), the thumbnail is generated once at record time from the plaintext .mov, before it is deleted. - SecureImageRepository: durable, encrypted video-thumbnail storage in Application Support (videoThumbnails/, excluded from backup) — generate from the plaintext .mov via AVAssetImageGenerator.image(at:), store encrypted with the current key, read+decrypt with an in-memory cache, delete one / delete all. - Security: thumbnails are derived from real frames, so deleteAllVideoThumbnails runs on poison-pill activation and security reset; per-video thumbnail (and any decoy copy) is removed when a video is deleted. - ThumbnailCache: video-name-keyed get/put/evict (prefixed). - CameraViewModel.encryptRecordedVideo generates+stores the thumbnail before the .mov is deleted. - VideoCellView loads the decrypted thumbnail via .task (mirrors PhotoCell), with a play badge and decoy shield; falls back to the icon placeholder. Scope: record-time only — videos recorded before this change and decoy videos (after the pill) show the placeholder. Tests (VideoThumbnailTests): store writes an encrypted file; read returns the image; delete removes it; poison pill wipes the whole thumbnails dir. Full unit suite: 97 passed, 0 failed.

Add scripts/check_test_target_membership.rb, which fails if any .swift under SnapSafeTests/ is not compiled by the target, and run it first in the fastlane build/test lanes (so CI's `fastlane test` and local runs both enforce it).

The video encryption service opens its output with FileHandle(forWritingTo:), which requires the file to already exist (the camera and the sharing path both pre-create it). So every decrypt/encrypt threw, addDecoyVideoWithKey caught it and returned false, and NO video was ever marked as a decoy. Consequences, both reported by the user: - Entering the poison PIN destroyed ALL videos, including ones the user tried to mark as decoys (deleteNonDecoyVideos found zero decoy files). - The decoy shield badge never appeared on video cells (isDecoyVideo was always false). Fix: pre-create the temp plaintext file and the decoy file before calling the encryption service, matching the camera/sharing pattern. Why tests missed it: FakeVideoEncryptionService wrote output via Data.write(to:), which creates the file, masking the missing precondition. The fake now models the real precondition (throws if the output file does not exist), so this class of bug is caught. With the faithful fake the two decoy tests went RED, then GREEN after the fix. Full suite: 0 failures.

On the last chunk that over-read swallowed the auth tag (and index/trailer), so the subsequent tag read returned nothing and decryption threw SECVError.fileIOError -- for essentially any video (almost all have a partial final chunk). This silently broke every bulk-decrypt caller, decryptVideoForSharing: - Marking a video as a decoy (addDecoyVideoWithKey decrypts then re-encrypts) always failed, so no video ever became a decoy. Hence the poison pill deleted ALL videos and the decoy shield badge never appeared. - Video sharing (also decryptVideoForSharing) was broken the same way. Playback was unaffected -- it streams via a custom AVAssetResourceLoader (makeEncryptedVideoAsset), a different path. Fix: read each chunk's actual size, min(chunkSize, originalSize - chunkIndex*chunkSize); AES-GCM ciphertext length equals the plaintext length, so this reads exactly the ciphertext and leaves the tag intact. This was the real root cause behind the decoy-video badge / "all videos deleted" reports (the earlier saveDecoySelections and pre-create fixes were necessary but not sufficient). Tests (DecoyVideoIntegrationTests): real-service encrypt/decrypt round-trips for single-chunk and multi-chunk-with-partial-last inputs (assert exact bytes), plus an end-to-end "mark video as decoy -> isDecoyVideo true" using the real VideoEncryptionService.

But decoy videos survive the pill, so they were left with no thumbnail -> the gallery showed the placeholder icon. Mirror the decoy-video mechanism for thumbnails: when a video is marked as a decoy, re-encrypt its thumbnail with the poison-pill key into a separate decoyVideoThumbnails/ directory. On the pill, after wiping the real-key thumbnails, restore the decoy thumbnails into videoThumbnails/. They are encrypted with the poison key (the active key after the pill), so readVideoThumbnail decrypts them normally; clearAllThumbnails() flushes the in-memory cache so no real thumbnail leaks. Cleanup: removeDecoyVideo drops the decoy thumbnail copy; securityFailureReset wipes the decoy thumbnail directory too. Test (VideoThumbnailTests): marking a video as a decoy stores a poison-key thumbnail; after the poison pill the decoy video's thumbnail is restored while a non-decoy video's thumbnail is destroyed.

Allow videos too: a picked video is copied to a temp file (ImportedMovie transferable), encrypted to SECV with the current key in the videos directory, and given a thumbnail -- mirroring the camera record path. Imported videos use the camera's "video_yyyyMMdd_HHmmss" naming (bumping the second on collision) so they stay unique and sort correctly. Tests (VideoImportTests + DecoyVideoIntegrationTests): import creates an encrypted .secv with the video_ prefix, the name is date-parseable/sortable, repeated imports get distinct names, a non-decodable input still encrypts but skips the thumbnail, and a real-service round-trip recovers the original bytes. Full suite: 0 failures.

The glass is intentionally non-interactive: these backgrounds sit inside Buttons and tap gestures, and interactive glass installs its own touch handling that swallowed the button taps (regression: the flash toggle could not be changed).

The detail route carried [PhotoDef] so videos were stripped before the pager started. Fix: AppDestination.photoDetail now carries [GalleryMediaItem] (the full mixed-media list). PhotoPageViewController creates a PhotoDetailHostingController for photos or an InlineVideoHostingController for videos, using the encryption key already on each GalleryMediaItem. All gallery taps route to .photoDetail with viewModel.mediaItems so swiping moves seamlessly between photos and videos in gallery order. InlineVideoPageView wraps VideoPlayerViewModel + AVKit VideoPlayer. Requires .onAppear { viewModel.setupPlayback() } — without it isLoading stays true forever and the spinner never resolves. EnhancedPhotoDetailViewModel works with [GalleryMediaItem]: currentPhotoDef / currentIsVideo gate photo-specific operations; preloading skips video items. Photo toolbar hides when the current page is a video (AVKit provides controls).

Photo and video pages now use one toolbar component. - Auto-hide rewritten: replaced the global Timer.publish with a per-show cancellable Task that resets on every interaction (play/pause, scrub start/end, tap-to-show) and waits 5s before fading. Scrubbing cancels the timer so the bar can't disappear mid-drag. - Play/pause hit area: added contentShape(Rectangle()) so the full 44x44 frame is reliably tappable instead of falling through to the surface tap that toggles control visibility. - Counter chip ("3 of 10") now fades in lockstep with the video controls via a callback plumbed through PhotoPageViewController to EnhancedPhotoDetailViewModel; photo pages remain unaffected. - Off-screen audio fix: the asset load now runs in a tracked Task that cleanup() cancels, and the completion bails out before player.play() when the task is cancelled -- so a slow decrypt can't auto-start audio on a page that's been swiped away. - Haptics: light sensory feedback on play/pause (keyed to isPlaying) and on every MediaToolbarButton tap, matching the camera/PIN vocabulary already in the app. The standard SwiftUI Slider continues to provide scrub haptics for free. - Project, strings catalog, and fastlane README updated for the new files and lanes. TODO.md adds a scratch list of unrelated observations.

An attacker who can race the device-lock state could turn that into a DoS. - Introduce `PinVerificationResult` (`success` / `invalidPin` / `failure(Error)`) and return it from `verifyPin` instead of `Bool`. - Catch derivation errors and surface them as `.failure`. - Update `PINVerificationViewModel` to treat `.failure` as a retryable error that does NOT increment failed-attempts (otherwise the same race could force a security reset). - Show the new retryable-error message in `PINVerificationView`. Test (red→green): `test_verifyPin_returnsRetryableFailure_whenKeyDerivationThrows` stubs `deriveAndCacheKey` to throw and asserts the use case returns `.failure` without crashing.

Ripples to `SecureImageRepository.evictKey/securityFailureReset/ activatePoisonPill` and `InvalidateSessionUseCase.invalidateSession` (now `async`); call sites updated to `await`. Tests (red-first, in `HardwareEncryptionSchemeSecurityResetTests`): - `test_securityFailureReset_deletesHardwareKeys` creates the KEK and `pin_key` via `encryptWithKeyAlias`, asserts they exist in the keychain, runs reset, and asserts both are gone. - `test_securityFailureReset_evictsCachedKeyBeforeReturning` derives a key, runs reset, and asserts `getDerivedKey()` throws `.keyNotDerived` on return — proving the cache was cleared before reset returned. Both tests failed before this change and pass after.

The DEK was derived from the PIN at create time (PBKDF2(PIN ‖ dSalt ‖ deviceID)) but only Secure-Enclave-wrapped on disk, so the load path reproduced the DEK from the SE alone — `deriveWrappedKey` never used its `plainPin` argument. The Argon2 PIN check was a Swift-level gate, not a cryptographic dependency. Anything reaching `SecKeyCreateDecryptedData` on an unlocked device (jailbreak, lldb attach, patched binary) recovered all content without the PIN. Fix: add a PIN-derived AES-GCM wrap layer *under* the SE wrap. create: DEK = random(32) // independent of PIN pinKey = PBKDF2("snapsafe-pinwrap-v1:" ‖ PIN ‖ deviceID, salt) stored = SE_wrap( AES-GCM(DEK, key: pinKey) ) derive: payload = SE_unwrap(stored) DEK = AES-GCM-open(payload, key: pinKey) // wrong PIN -> .wrongPin Recovering the DEK now requires the user to actively type the PIN. Chosen over `.userPresence` / biometric ACLs deliberately: biometrics and the device passcode are coercible (sleeping/forced face, border demand), the PIN is not — SnapSafe's threat model is compelled-access resistance. See design/2026-05-31-c1-pin-binding-analysis. Details: - New `PinDEKWrapper` (CryptoKit + PBKDF2, keychain-free → unit-testable on CI): derivePinKey / wrap / unwrap / isLegacyRawDEK. - `CryptoError.wrongPin` (+ Equatable) for clean, non-leaky wrong-PIN failures. - One-shot transparent migration: a legacy 32-byte raw-DEK payload is preserved (existing content depends on its value) and re-wrapped under the PIN key on next valid unlock. 32-byte raw vs 60-byte wrapped is the discriminator. - Removed now-dead PIN→DEK PBKDF2 path (`derivePBKDF2Key`, `dSaltSize`). - UX unchanged: same `deriveAndCacheKey` signature, same session model. Tests (TDD): 10 PinDEKWrapper unit tests (determinism, wrong-PIN rejection, no-plaintext-leak, nonce freshness, payload length, migration discriminator) run on CI; 3 scheme-level integration tests (round trip, wrong-PIN, stored payload is PIN-wrapped) run on device, skip on simulator (Secure Enclave). Full suite: TEST SUCCEEDED, 0 failures. Addresses C1 from the 2026-05-31 security review.

On an invalid PIN, VerifyPinUseCase called incrementFailedAttempts() — which authoritatively bumps the persisted count AND records the last-failed timestamp + monotonic backoff baseline. Then PINVerificationViewModel ALSO wrote the counter via setCurrentFailedAttempts(failedAttempts + 1), derived from its stale local @Published value and without touching the backoff timestamp/baseline. The two writes happened to align today, but the design was racy (the VM's local value updates asynchronously in a Task) and could desync the count from the backoff window — a value the lockout/security-reset logic depends on. Fix: make the repository the single writer; the view model only observes. - PinVerificationResult.invalidPin now carries `failedAttempts: Int`, the authoritative post-increment count returned by the repository's single increment. - VerifyPinUseCase returns that count; the view model reflects it into its @Published property and uses it for the MAX-attempts check — it no longer writes the counter. - On success the VM just sets failedAttempts = 0 locally (AuthorizePinUseCase already reset the persisted counter); the redundant write is gone. - Removed the now-dead setCurrentFailedAttempts(_:) helper. Tests (TDD): added test_verifyPin_onInvalidPin_incrementsCounterExactlyOnce_ andReturnsNewCount — asserts the persisted counter goes 0 -> 1 on one invalid attempt and the result carries count 1. Full suite: TEST SUCCEEDED, 0 failures. Addresses M1 from the 2026-05-31 security review.

Apply `.completeFileProtection` to the write so the file is unreadable when the device is locked (defense-in-depth at rest). This is Option D from the H2 risk discussion: a hardening pass, not a full remediation. The reversible PP PIN still exists because decoy creation needs to reproduce the poison-pill encryption key while the user is in their normal session (AddDecoyPhoto/VideoUseCase). The deeper fix (wrap the poison-pill DEK under the primary PIN key, à la C1, and drop the reversible PIN) is deferred — the residual exposure (recover the PP PIN value via instrumented access on an unlocked device) was assessed as mostly theoretical. See decisions/2026-06-01-poison-pill-pin-accepted-risk. Test (device-only; skips on simulator where file protection isn't enforced): asserts the settings file has `.complete` protection after a PP PIN is stored. Full suite: TEST SUCCEEDED, 0 failures. Addresses H2 (partial / accepted residual risk) from the 2026-05-31 security review.

Diagnostics showed that on PHYSICAL rotation iOS injects a ~48pt phantom safe-area inset even though the interface never leaves portrait, which shrank the content area from the bottom and shoved the bottom controls (mode toggle + gallery/shutter/settings) up over the preview. Fix: make the camera ignore the safe area entirely and lay all controls in one column padded by the STABLE window safe-area insets instead of the rotation-sensitive SwiftUI safe area. Removes the fragile .safeAreaInset(.bottom) bar. The layout is now immune to the phantom inset, so nothing moves on rotation.

After the first tap the focus recognizer started winning, so taps on the flash button (and other controls) were routed to 'focus' — which ignored them as outside the capture area — instead of the button, making the flash appear stuck after one toggle. Give the tap recognizers a delegate that only accepts touches inside the capture-area container; touches outside it (the overlaid controls and letterbox) are declined and fall through to SwiftUI.

Isolate the type to @MainActor so every access to its mutable state is serialized on one actor. A nonisolated init keeps it constructible from the non-isolated DI factory closures. The single non-main caller (AuthorizePinUseCase) now awaits authorizeSession(). HashedPin is marked Sendable so it can cross the actor boundary into the encryption scheme. Adds a concurrency test that hammers session mutations from a task group and asserts consistent, crash-free settling.

Concurrent verification attempts could read the same value and write the same result, losing an increment and undercounting the PIN brute-force lockout — a security-relevant TOCTOU that @MainActor isolation alone does not fix (the awaits still interleave). Add SettingsDataSource.incrementFailedPinAttempts(), which performs the read-modify-write inside the data source's own critical section (FileBasedSettingsDataSource: a single barrier block; UserDefaults: an NSLock-guarded section). AuthorizationRepository now delegates to it. Adds a test firing many concurrent increments and asserting the final count equals the attempt count.

If you want to make some text bold, always use `bold()` instead of `fontWeight(.bold)`. +- Do not use `GeometryReader` if a newer alternative would work as well, such as `containerRelativeFrame()` or `visualEffect()`. +- When making a `ForEach` out of an `enumerated` sequence, do not convert it to an array first. So, prefer `ForEach(x.enumerated(), id: \.element.id)` instead of `ForEach(Array(x.enumerated()), id: \.element.id)`. +- When hiding scroll view indicators, use the `.scrollIndicators(.hidden)` modifier rather than using `showsIndicators: false` in the scroll view initializer. +- Use the newest ScrollView APIs for item scrolling and positioning (e.g. `ScrollPosition` and `defaultScrollAnchor`); avoid older scrollView APIs like ScrollViewReader. +- Place view logic into view models or similar, so it can be tested. +- Avoid `AnyView` unless it is absolutely required. +- Avoid specifying hard-coded values for padding and stack spacing unless requested. +- Avoid using UIKit colors in SwiftUI code. + + +## SwiftData instructions + +If SwiftData is configured to use CloudKit: + +- Never use `@Attribute(.unique)`. +- Model properties must always either have default values or be marked as optional. +- All relationships must be marked optional. + + +## Project structure + +- Use a consistent project structure, with folder layout determined by app features. +- Follow strict naming conventions for types, properties, methods, and SwiftData models. +- Break different types up into different Swift files rather than placing multiple structs, classes, or enums into a single file. +- Write unit tests for core application logic. +- Only write UI tests if unit tests are not possible. +- Add code comments and documentation comments as needed. +- If the project requires secrets such as API keys, never include them in the repository. +- If the project uses Localizable.xcstrings, prefer to add user-facing strings using symbol keys (e.g. helloWorld) in the string catalog with `extractionState` set to "manual", accessing them via generated symbols such as `Text(.helloWorld)`.

Cause: `EnhancedPhotoDetailViewModel.handleDragChanged` re-checks + `abs(translation.height) > abs(translation.width)` on *every* update and + silently drops updates when the cumulative translation turns more + horizontal than vertical. The drag also forces `dragOffset.width = 0`, so + the image never follows the finger sideways. +2. **Video pages drag inconsistently.** The photo action toolbar lives outside + the transformed pager layer (stationary during drag), but the video + transport bar and action toolbar are rendered inside `InlineVideoPlayerView` + — inside the layer that receives the dismiss transform — so they move with + the video. +3. **No pinch-zoom on videos.** Photos zoom via `ZoomableScrollView` + (UIScrollView); the video page renders a bare `AVPlayerLayer` surface. +4. **Capture framing ≠ preview framing.** The session uses the `.high` preset: + the preview feed, captured photos, and videos are all 16:9 (1920×1080). The + preview is aspect-FILLED into a hard-coded 3:4 container + (`CameraPreviewView.photoAspectRatio`), cropping the top and bottom on + screen. Captures keep the full 16:9 frame, so saved media shows strips + above and below what the preview displayed. `.high` also caps stills at + ~2MP. + +## Decisions (user-confirmed) + +- **Controls fade out during the dismiss drag** (Apple Photos behavior), for + both photos and videos. They fade back if the drag is cancelled. +- **Preview shows the full 16:9 capture frame** (WYSIWYG). No cropping of + captures; photos and videos share identical framing. + +## Design + +### 1. Free-floating dismiss drag + +In `EnhancedPhotoDetailViewModel`: + +- Add a per-gesture **direction latch** (`dragMode`), set once on the first + `onChanged` of a gesture: initial direction predominantly vertical → dismiss + mode for the rest of the gesture; horizontal → not a dismiss drag (pager + pages as today). No per-update re-checking. +- In dismiss mode, `dragOffset` tracks the **full 2D translation** (width no + longer forced to 0). `dismissProgress` still derives from vertical travel + only. `DismissTransformModifier` applies both axes. +- `handleDragEnded` resets the latch; the existing dismiss threshold / + velocity logic is unchanged. +- While a dismiss drag is engaged, the pager's horizontal scroll is disabled + via the existing `updatePagingEnabled` pathway (extended to consider + "dismiss drag active" alongside `isZoomed`). + +Latch logic lives in the view model and gets unit tests (same style as +`mayDismissByDrag`). + +### 2. Chrome fades during the drag + +- New shared `ObservableObject` (`PagerChromeState`, single published flag + `isDismissDragging`), owned by `EnhancedPhotoDetailView`, passed into + `PhotoPageViewController` and injected into each hosted page's root view via + `.environmentObject`. +- Photo toolbar + counter chip (already outside the pager layer): opacity tied + to the drag — fade out when the dismiss drag latches, fade back on cancel. + Toolbar gets `allowsHitTesting(false)` while hidden. +- `InlineVideoPlayerView` observes `PagerChromeState` and hides its transport + bar + action toolbar with the same animation while dragging. With controls + hidden, nothing visible moves with the video — resolving the inconsistency + without restructuring the video page hierarchy. + +### 3. Pinch-zoom for videos + +- Wrap `VideoSurfaceView` in the existing `ZoomableScrollView` inside + `InlineVideoPlayerView`, same configuration as photos (1×–6×). Pinch, + pan-while-zoomed, double-tap zoom, and centering come free; `AVPlayerLayer` + keeps rendering while scaled, so zoom works during playback and while + paused. +- Thread the same `isZoomed` binding photos use through + `InlineVideoHostingController` so paging disables while zoomed and the + dismiss gate (`mayDismissByDrag`) works unchanged. +- Tap conflict: the video page toggles controls on single tap, and + `ZoomableScrollView` owns a UIKit double-tap recognizer. Add an optional + `onSingleTap` callback to `ZoomableScrollView`, wired with + `require(toFail: doubleTap)`, and move the controls toggle there — double + tap zooms without flashing the controls. + +### 4. Camera preview = capture frame (WYSIWYG) + +In `CameraPreviewView` / `CameraDeviceService`: + +- The preview container's aspect ratio is **derived from the active capture + format's dimensions** (e.g. 1920×1080 under `.high` → 9:16 portrait), with + 9:16 as the fallback — not a new hard-coded constant, so it stays correct if + the preset changes. +- `videoGravity` stays `.resizeAspectFill`; with the container matching the + feed ratio, fill ≡ fit and nothing is cropped. +- Border/corner brackets already lay out from the container size — they adapt. + Tap-to-focus conversion goes through `captureDevicePointConverted`, which + accounts for gravity — unaffected. +- Raise still resolution: set the photo output's `maxPhotoDimensions` (and the + per-capture `photoSettings.maxPhotoDimensions`) to the active format's + largest entry in `supportedMaxPhotoDimensions` (~4032×2268, still 16:9). + +## Out of scope + +- Cropping captures to a 3:4 window (rejected: lossy, and video would need + re-encoding through the encrypted pipeline). +- Mode-dependent aspect ratios (rejected: photos and videos must share + framing). +- UIKit interactive-transition rewrite of the dismiss gesture. + +## Error handling + +No new failure paths. Gesture changes are pure state-machine logic in the +view model. `maxPhotoDimensions` is set only from values the format reports in +`supportedMaxPhotoDimensions`. + +## Testing + +- Unit tests for the drag latch state machine (engage vertical, ignore + horizontal, full-2D offset while latched, reset on end). +- Manual on-device verification: + - Drag photo and video through all four screen regions, including over the + toolbar area; verify no catching, chrome fades out and back, cancel and + complete both work. + - Pinch video while playing and while paused; pan while zoomed; double-tap + zooms in/out without toggling controls; paging disabled while zoomed. + - Capture a photo and a video; compare framing edge-for-edge against the + preview; verify still resolution is the format max.

The camera preview container derives its aspect ratio from the active capture format instead of a hard-coded 3:4, and still resolution is raised to the format max. + +**Tech Stack:** SwiftUI + UIKit interop (`UIViewRepresentable`/`UIHostingController`), AVFoundation, XCTest. + +**Spec:** `docs/superpowers/specs/2026-06-11-media-viewer-ux-design.md` + +**Build/test commands** (run from repo root `/Users/bill/src/snapsafe/SnapSafe`): + +- Full unit tests: `bundle exec fastlane test` +- One test class (faster, used in steps below): + `xcodebuild test -workspace SnapSafe.xcworkspace -scheme SnapSafe -destination 'platform=iOS Simulator,name=iPhone 17' -only-testing:SnapSafeTests/ -quiet` +- Compile check only: + `xcodebuild build -workspace SnapSafe.xcworkspace -scheme SnapSafe -destination 'platform=iOS Simulator,name=iPhone 17' -quiet` + +New `.swift` files are picked up automatically (file-system-synchronized groups, `objectVersion = 70`). `scripts/check_test_target_membership.rb` (run by the fastlane `test` lane) guards test-target membership. + +**Codebase conventions (from AGENTS.md):** new shared state uses `@MainActor @Observable` (not `ObservableObject`); no `DispatchQueue.main.async` in new code; existing `ObservableObject` view models stay as they are. + +--- + +### Task 1: Direction-latched dismiss drag (view model state machine) + +The bug: `handleDragChanged` re-checks `abs(height) > abs(width)` on every update and drops updates when the cumulative translation turns horizontal — the image freezes ("catches").

From 6d0e3745c12cee29a7c1532ba956908c0dc18062 Mon Sep 17 00:00:00 2001 From: Bill Booth Date: Thu, 11 Jun 2026 22:43:13 -0700 Subject: [PATCH 066/127] fix(viewer): latch dismiss-drag direction once and track both axes Re-checks direction on every gesture update were dropping updates when cumulative translation turned horizontal, freezing the dragged image. Direction is now latched from the first movement of each gesture via a DismissDragMode state machine (undecided/dismissing/rejected); while dismissing the offset follows the finger on both X and Y axes. Also fixes a pre-existing Swift 6 concurrency error in the UI test target that blocked all test runs.

It is `import UIKit`, returns `UIImage` from the data layer, and runs all disk ++ crypto on the main thread. It is the top structural finding (P1) of the +[architecture audit vs. SecureCameraAndroid](../../../../notes/bill-dev-notes/Projects/SnapSafe/design/architecture-audit-vs-android.md), +which measured SnapSafe against the Kotlin app +[SecureCamera/SecureCameraAndroid](https://github.com/SecureCamera/SecureCameraAndroid). + +This refactor aligns the type with that app's Clean-Architecture layering: data sources do +only data handling, repositories hold core domain functions off the main thread, and image +decoding is a UI-boundary concern. + +## Goal + +Decompose the god-class into three focused units and route the gallery thumbnail views +through their ViewModels: + +1. A pure image utility (no I/O, no crypto). +2. A storage data source (the single filesystem touchpoint for media). +3. A slim, off-main `actor` repository that returns `Data` (not `UIImage`). + +## Decisions (locked during brainstorming) + +- **Scope:** Full Clean split — responsibility split **plus** drop `@MainActor` (→ `actor`) + **plus** repo deals in `Data`, with `UIImage` decode moving to the ViewModel boundary. +- **P2 coupling:** Fix the gallery thumbnail call sites (`PhotoCell`, `SecureGalleryView`) by + routing them through their ViewModels. Adapt `VideoPlayerView` only enough to compile; its + full logic extraction is a separate, deferred P2 effort. + +## Target components + +### 1. `ImageProcessing` — pure, stateless, `nonisolated` / `Sendable` +Holds all UIKit/ImageIO work currently in the repo: JPEG compression, rotation, +resize/downscale, EXIF extract/apply, `CGImagePropertyOrientation` mapping, image-metadata +parsing, and `UIImage.sensorBitmap` handling. Boundary types are `Data` in / `Data` out +wherever possible; `UIImage`/`CGImage` stay internal. No file I/O, no encryption. +Independently unit-testable. Lives in `SnapSafe/Data/SecureImage/ImageProcessing.swift`. + +### 2. `PhotoStorageDataSource` — data handling only +Owns the directory layout (`photos`, `decoys`, `videos`, `videoThumbnails`, +`decoyVideoThumbnails`, `.thumbnails`), directory creation + `isExcludedFromBackup` resource +values, raw encrypted file I/O (`encryptToFile`, `decryptFile`), and file enumeration / delete. +Depends on `EncryptionScheme` (already `Sendable`) + `FileManager`. Becomes the single place +that touches the filesystem for media — and the future home for the P3 `FileManager` work now +in `MixedMediaGalleryViewModel` / `CameraViewModel` (seam created here, not filled). + +### 3. `SecureImageRepository` (slimmed) → `actor` +Core domain functions only: photo / video / decoy / poison-pill operations, `getPhotos`, +deletes, save / update, metadata. Coordinates `PhotoStorageDataSource` (I/O) + `ImageProcessing` +(CPU) + `EncryptionScheme`. No `@MainActor`. **Read APIs return `Data`**, not `UIImage` +(`readImage` → `Data`, `readThumbnail` → `Data?`, `readVideoThumbnail` → `Data?`, +`getPhotoMetaData` → `PhotoMetaData`). + +### 4. ViewModel boundary +ViewModels decode `Data → UIImage` on `@MainActor` for display and expose it via `@Published`. + +## Required collaborator change + +`ThumbnailCache` is a `@MainActor class`; for the repo to be a clean `actor` it must cross the +actor boundary, so convert `ThumbnailCache` to an `actor`. Verify and, if needed, annotate +`VideoEncryptionServiceProtocol` as `Sendable`. `EncryptionScheme` is already `Sendable`. + +Rationale: the existing +[swift-concurrency-review](../../../../notes/bill-dev-notes/Projects/SnapSafe/design/swift-concurrency-review.md) +establishes the team rule that `@MainActor` is for types that drive `@Published` UI state. A +heavy I/O + crypto repository is not such a type, so an off-main `actor` is the consistent choice. + +## Data flow (thumbnail example) + +`PhotoCell` (view) binds to `@Published thumbnail` on its ViewModel → the VM calls +`await repo.readThumbnail(photo) -> Data?` (actor, off-main) → the VM decodes `UIImage(data:)` +on `@MainActor` → sets `@Published`. The view no longer `@Injected`s the repository. + +## Error handling + +Method contracts are unchanged — methods `throw` or return optional / `Bool` as today; failures +log via `Logger` and degrade.

The repository may keep an internal `Data` cache if re-decrypt cost warrants. +- Fix actor reentrancy on read-through paths (capture locals across `await`; optionally coalesce in-flight loads). +- Re-verify `rotateImage`/`resizeImage` thread safety off the main actor; migrate to `UIGraphicsImageRenderer` if needed. +- Route `PhotoCell` + `SecureGalleryView` through the shared `MixedMediaGalleryViewModel` via `.task(id: photo.id)` (cancels on reuse/scroll); remove their `@Injected(\.secureImageRepository)`. Adapt `VideoPlayerView` minimally to compile (full extraction is a separate P2 effort). +- Verify `VideoEncryptionServiceProtocol` is `Sendable`. +- Adjust `SecureImageRepositoryTests` for `Data` returns; add a task-group reentrancy/concurrency test mirroring the `AuthorizationRepository` pattern. + +--- + +## Self-review (against the spec) + +- **Spec coverage:** PR1 implements the `ImageProcessing` component (spec §Components.1) fully; PR2 covers `PhotoStorageDataSource` (§Components.2); PR3 covers the `actor` repo + `Data` boundary + `ThumbnailCache` + per-cell loading (§Components.3–4, §Required collaborator changes, §Concurrency & SwiftUI review notes). All spec sections map to a PR. +- **Placeholders:** PR1 contains complete code for every changed file and exact call-site edits. PR2/PR3 are explicitly labeled roadmaps (not executable tasks yet) by design — to be expanded post-PR1. +- **Type consistency:** `ImageProcessing` method names match the originals exactly (`compressImageToJpeg`, `rotateImage`, `resizeImage`, `cgImageOrientation`, `applyImageMetadata`, `extractEXIFMetadata`, `processImageWithEXIFMetadata`), so call-site edits are pure `ImageProcessing.` prefixes. `ImageRepositoryError` is reused, not redefined.

First-responder acquisition is driven by the field's didMoveToWindow plus a bounded spaced retry, instead of a single fire-once attempt that raced the security overlay / scene-activation transition and silently failed ~half the time (no cursor, no keyboard). PINVerificationView drops the obsolete @FocusState (and the lock-icon slide animation that depended on it), computes shouldFocus from scenePhase + isLoading, and unifies the scenePhase handler around != .active so all non-active transitions clear the PIN.

The coordinator's textFieldShouldEndEditing returned false while enabled, so the winning (hidden) field never resigned and permanently blocked the visible field against auto-focus and taps. - Make the security overlay the sole PIN surface; ContentView no longer pushes .pinVerification (root stays Color.clear while the overlay gates). - Remove the refuse-to-resign textFieldShouldEndEditing override. - Drive first responder from the field's window lifecycle (didMoveToWindow + bounded retry) instead of a single fire-once attempt.

This fixes P2 (view ↔ data) - without a view-model-per-cell explosion. -- **ViewModels stay `ObservableObject` / `@Published` for now.** Modern guidance prefers the - `@Observable` macro, but SnapSafe's VMs are uniformly `ObservableObject` and the `@Observable` - migration is a separately-tracked effort ("What's left" in the project hub).

The video detail view has no equivalent — there is no Info button on the video toolbar and no way for a user to see when or where a video was captured.

Immediately before `startRecording`, sample `let location = locationRepository.lastLocation`. -3. Build `[AVMetadataItem]` via a new `AVMetadataItemFactory.makeCaptureItems(location:date:)`.

For imported `.mov` (non-encrypted): use the file URL directly. -3. `await asset.load(.commonMetadata, .duration, .tracks)`. -4. Walk `commonMetadata`: find `kCommonIdentifierLocation` → parse ISO 6709 → `GpsCoordinates`. If absent, location = `nil`. -5. Find `kCommonIdentifierCreationDate` → `Date` (`dateTakenSource = .embedded`). If absent, fall back to `videoDef.dateTaken()` which parses the filename (`dateTakenSource = .filename`). If both are unavailable, use `Date(timeIntervalSince1970: 0)` — matches the photo behavior at `SecureImageRepository.getPhotoMetaData` line ~665. -6. From the first video track: `naturalSize` → resolution; `nominalFrameRate` → frame rate; `estimatedDataRate` → bitrate; `formatDescriptions[0]` FourCC → human codec string (e.g., `"hvc1"` → `"HEVC"`, `"avc1"` → `"H.264"`). -7. Compute orientation from `track.preferredTransform`. Decode the rotation angle (0° / 90° / 180° / 270°) and map to the existing `TiffOrientation` enum used by photos (1 / 6 / 3 / 8 respectively). Non-90°-multiple rotations are rare in practice; map to `.up` (1) as a safe default. -8.

Leading position, matching the photo toolbar's Info button placement. Calls `onInfo` like the photo path. - -**`Util/AppNavigation.swift`** — add `case videoInfo(VideoDef)` to the sheet enum (mirrors `case photoInfo(PhotoDef)`). - -**`Screens/ContentView.swift`** — render `VideoInfoView(videoDef:)` for the new sheet case (mirrors the photo case at line 125). - -**`Screens/PhotoDetail/EnhancedPhotoDetailView.swift`** — wire `onInfo: { nav.presentSheet(.videoInfo(currentVideoDef)) }` in the video branch. - -**`Localizable.xcstrings`** — new strings for the video-section labels (Duration, Codec, Frame Rate, Bitrate). All other labels (Filename, Resolution, File Size, Date Taken, Orientation, Location, etc.) are already in the catalog from the photo info sheet and are reused as-is. - -**`Util/AVMetadataItemFactory.swift`** is placed under `SnapSafe/Util/` so it's reachable from both `VideoCaptureService` (write side) and `SecureImageRepository` (read side, if shared ISO-6709 parsing helpers live there). - -### Dependency wiring - -`VideoCaptureService` constructor gains a `LocationRepository` parameter. Update the call site (wherever it's currently constructed — likely `CameraView` or a Factory) to pass it. `LocationRepository` is already shared with `PhotoCaptureService`, so no new singleton. - -## Error handling - -- `getVideoMetaData` is `async throws`. Underlying failures (file missing, decryption error, AVAsset load timeout) propagate up. `VideoInfoViewModel` catches and shows a single error row in place of the sections, matching how `ImageInfoViewModel` handles its load failures. -- Missing-metadata case is NOT an error — it's the documented fallback path (location = nil, date from filename). -- Best-effort field parsing: if an individual track field (e.g., `nominalFrameRate`) is `0` or unavailable, the corresponding `VideoMetaData` field is `nil` and the UI shows "—" for that row. One bad field doesn't fail the sheet. - -## Testing - -Unit: -- `AVMetadataItemFactory.makeCaptureItems` produces `kCommonIdentifierLocation` in ISO 6709 format for representative coordinates (positive/negative lat, positive/negative long, near-zero), and omits the location item when `location: nil`. -- `AVMetadataItemFactory.makeCaptureItems` produces `kCommonIdentifierCreationDate` matching the input `Date`. -- ISO 6709 round-trip: `GpsCoordinates → AVMetadataItem → parsed back → GpsCoordinates` preserves coordinates to within `1e-6` degrees. - -Integration: -- **Round-trip with metadata**: Build a synthetic `.mov` via `AVAssetWriter` with the factory's items, encrypt via `VideoEncryptionService.encryptVideoForDecoy`, then call `getVideoMetaData` on the resulting `VideoDef`. Assert: location matches, date matches, resolution matches, duration matches. -- **Backwards-compat**: Encrypt a `.mov` *without* any custom metadata, call `getVideoMetaData`. Assert: location is `nil`, `dateTakenSource == .filename`, `dateTaken` matches the value parsed from the filename, technical fields (resolution, duration, codec) still populated. -- **Imported video**: Take a `.mov` with pre-existing GPS metadata (constructed via `AVAssetWriter` with a different `kCommonIdentifierLocation`), encrypt via the import path, call `getVideoMetaData`. Assert: pre-existing GPS is preserved and returned. - -No new UI tests (existing pattern: ImageInfoView has no unit tests; manual verification on the simulator covers the sheet rendering). - -## Out of scope (deferred) - -- Editing metadata (no UI to change a video's capture date or location after-the-fact). -- "All Metadata" debug dump section (could be added later; mirrors a deferred photo nicety). -- SECV format version / encrypted file size / chunk count display. -- Per-clip metadata refresh on the file (the metadata is whatever was captured; no later edits).

The files aren't in the Xcode project, DI registrations are missing, and the camera doesn't trigger encryption after recording. This checklist tracks connecting all the existing pieces and filling the remaining gaps, mirroring the Android reference implementation's flow: **record → encrypt → gallery → playback → share**. - ---- - -## Phase 1: Project Foundation & DI Wiring - -- [ ] **1a. Add missing files to Xcode project** - - `SnapSafe/Data/Encryption/VideoEncryptionService.swift` - - `SnapSafe/Util/EncryptedVideoDataSource.swift` - - `SnapSafe/Screens/PhotoDetail/VideoPlayerView.swift` - - `SnapSafe/Screens/Gallery/MixedMediaGalleryViewModel.swift` - - `SnapSafe/Data/Models/MediaItem.swift` - -- [ ] **1b. Register VideoEncryptionService in DI container** - - File: `SnapSafe/Data/AppDependencyInjection.swift` - - Add `var videoEncryptionService: Factory` registration - -- [ ] **1c. Fix compile errors** - - Verify `MediaItem` protocol conformance on `PhotoDef` and `VideoDef` - - Verify `MixedMediaGalleryViewModel` compiles with DI injection - - Verify `Logger` extensions don't conflict - ---- - -## Phase 2: Post-Recording Encryption Pipeline - -- [ ] **2a. Add encryption callback to VideoCaptureService** - - File: `SnapSafe/Screens/Camera/Services/VideoCaptureService.swift` - - Add `var onRecordingFinished: ((URL) -> Void)?` callback - - Call it in `fileOutput(_:didFinishRecordingTo:from:error:)` on success - -- [ ] **2b. Wire encryption in CameraViewModel** - - File: `SnapSafe/Screens/Camera/CameraViewModel.swift` - - Inject `VideoEncryptionService` and get encryption key from auth - - After recording: encrypt .mov → .secv, then delete .mov - - Add `@Published var isEncryptingVideo: Bool` - - Add `@Published var encryptionProgress: Double` - -- [ ] **2c. Add encryption progress UI in CameraView** - - Show progress indicator when `isEncryptingVideo` is true - - Prevent or warn on navigation during encryption - ---- - -## Phase 3: Gallery Integration - -- [ ] **3a. Switch gallery to MixedMediaGalleryViewModel** - - File: `SnapSafe/Screens/Gallery/SecureGalleryView.swift` - - Replace `SecureGalleryViewModel` with `MixedMediaGalleryViewModel` - - Pass encryption key from auth context - -- [ ] **3b.

Add video playback navigation** - - File: `SnapSafe/Screens/AppNavigation.swift` — add `.videoPlayer(VideoDef, SymmetricKey?)` destination - - File: `SnapSafe/Screens/ContentView.swift` — route to `VideoPlayerView` - -- [ ] **3d. Pass encryption key through navigation** - - Flow: auth → gallery → video player - - Ensure key is available for encrypted video playback - ---- - -## Phase 4: Security & Cleanup - -- [ ] **4a. Add video cleanup to SecurityResetUseCase** - - File: `SnapSafe/Data/UseCases/SecurityResetUseCase.swift` - - Delete all files in `ApplicationSupport/videos/` - -- [ ] **4b. Clean up stranded temp files on app launch** - - Scan for `.mov` files in videos directory on startup - - Delete them (safer than re-encrypting) - -- [ ] **4c. Session invalidation cleanup** - - File: `SnapSafe/Data/UseCases/InvalidateSessionUseCase.swift` - - Clear cached decrypted video data on session invalidation - ---- - -## Phase 5: Video Sharing - -- [ ] **5a. Verify sharing flow** - - `MixedMediaGalleryViewModel.prepareAndShareMedia()` already has video decryption - - Confirm decryption-for-sharing works end-to-end - - Verify temp decrypted files are cleaned up after sharing - ---- - -## Phase 6: Build & Verify - -- [ ] **6a. Build succeeds** — `xcodebuild build` with no errors -- [ ] **6b. Unit tests pass** — `SECVFileFormatTests` -- [ ] **6c. Manual flow test:** - - Switch to video mode → record → stop - - Verify .mov encrypted to .secv, then .mov deleted - - Gallery shows video with icon overlay - - Tap video → plays via encrypted data source - - Share video → temp decrypt → share sheet - - Security reset → all videos deleted - ---- - -## Key Files - -| File | Action | -|------|--------| -| `project.pbxproj` | Add 5 missing Swift files to build | -| `AppDependencyInjection.swift` | Register VideoEncryptionService | -| `VideoCaptureService.swift` | Add recording-finished callback | -| `CameraViewModel.swift` | Wire post-recording encryption | -| `CameraView.swift` | Add encryption progress UI | -| `SecureGalleryView.swift` | Switch to mixed media ViewModel | -| `AppNavigation.swift` | Add video player destination | -| `ContentView.swift` | Route video player destination | -| `SecurityResetUseCase.swift` | Add video directory cleanup | From 4c8c843660bc1eadc1d3edf27395e103c6bf481c Mon Sep 17 00:00:00 2001 From: Bill Booth Date: Sun, 14 Jun 2026 22:52:17 -0700 Subject: [PATCH 116/127] Change session timeout to 5min This is to bring ios inline with android. --- SnapSafe/Data/UserData/UserDefaultsSettingsDataSource.swift | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/SnapSafe/Data/UserData/UserDefaultsSettingsDataSource.swift b/SnapSafe/Data/UserData/UserDefaultsSettingsDataSource.swift index 1e37d85..5a94524 100644 --- a/SnapSafe/Data/UserData/UserDefaultsSettingsDataSource.swift +++ b/SnapSafe/Data/UserData/UserDefaultsSettingsDataSource.swift @@ -27,7 +27,7 @@ private enum PrefKeys: String { enum Defaults { static let sanitizeFileName: Bool = true static let sanitizeMetadata: Bool = true - static let sessionTimeoutMs: Int64 = 60_000 + static let sessionTimeoutMs: Int64 = 300_000 } // MARK: - UserDefaults Impl From 8bbad6944c566a5e17ad3111096861dc4f218ecb Mon Sep 17 00:00:00 2001 From: Bill Booth Date: Mon, 15 Jun 2026 00:57:22 -0700 Subject: [PATCH 117/127] Length warning on PIN setup --- SnapSafe.xcodeproj/project.pbxproj | 4 ++++ SnapSafe/Screens/PinSetup/PINSetupView.swift | 14 ++++++++++++-- SnapSafe/Screens/PinSetup/PINStrings.swift | 8 ++++++++ .../PoisonPillPinCreationView.swift | 14 ++++++++++++-- 4 files changed, 36 insertions(+), 4 deletions(-) create mode 100644 SnapSafe/Screens/PinSetup/PINStrings.swift diff --git a/SnapSafe.xcodeproj/project.pbxproj b/SnapSafe.xcodeproj/project.pbxproj index c8e1a49..d6d84f3 100644 --- a/SnapSafe.xcodeproj/project.pbxproj +++ b/SnapSafe.xcodeproj/project.pbxproj @@ -114,6 +114,7 @@ A91DBC6D2DE58191001F42ED /* FaceDetector.swift in Sources */ = {isa = PBXBuildFile;
