🛰️ Three days: from empty folder to family gallery

"Private photo and video gallery for a small circle. UI title: Foto galleriet."
— docs/ARCHITECTURE.md, line 3

Three days ago, storage/worktrees/memoria/ was a folder with an empty .git and a 9-byte README. Right now the screen is on fire with 370+ commits after an intense sprint, a Laravel backend with 17 migrations, an Android app that has its own map of every photo with GPS, and a Windows companion sitting in the system tray waiting for me to slot an SD card into the card reader. This isn't "a gallery MVP". It's the start of a private photo ecosystem.

Let me try to lay out what's actually happened.

The philosophy — what makes this different

The brainstorm document (docs/memoria-brainstorm.md) sets two premises early and hammers them home:

1. Auto-sync is the engine, not a feature. "Google Photos wins because it's frictionless — the photo is just there after you took it. If we end up requiring a manual upload ceremony, we've already lost."

2. Feed > Dashboard. The front page is a family feed, Instagram-ish: "Maria shared 12 photos in Gran Canaria - Day 3", "Dad dropped 3 videos in Sommerhus". Widget-grid dashboards are secondary, for power users. What we have to close in MVP is one loop: I take a photo → my wife gets a notification ~15s later → she sends a heart → I see the reaction. That's the flywheel. Everything else is polish.

And then a third, non-negotiable requirement: metadata is core. EXIF, GPS, camera serial, lens, exposure — preserved intact from device to server to disk. Clients MUST NOT re-encode during upload. If we don't build this right from the start, we retroactively lose options for every early-uploaded photo. That line is set in stone.

Stack — and why

Backend: Laravel 12 + Filament 5, Livewire 4 + Alpine + Tailwind 4 + Vite 7. MySQL 8 in prod, MariaDB on the LXC. Sanctum for auth (cookie for web, long-lived PAT for Android). Centrifugo 6 for realtime — same setup as oUTPOSt's Command Center, where we've already paid the learning cost. Firebase Cloud Messaging for push.

Native clients: Android in Kotlin/Jetpack Compose (Hilt, Room, WorkManager, ExoPlayer/Telephoto, Coil 2, osmdroid). Windows in WinUI 3 unpackaged + .NET 9 (EF Core, Serilog, IHost, DPAPI for token storage).

Infra: Own LXC on the Proxmox host (Debian 12, dedicated 3TB raid disk mounted at /mnt/memoria-data/). Public hostname foto.kreden.dk via reverse proxy + Let's Encrypt. Not sharing database/Centrifugo/Redis with oUTPOSt — Memoria stands on its own.

Everything is provisioned by infra/proxmox/create-memoria-lxc.sh + infra/memoria-provision.sh. A php artisan memoria:deploy mirrors outpost:deploy, and there's a _ctl_memoria.php zero-Laravel-deps CTL in the same style. Reuse is the mantra.

Backend — gates, services, and a 26 KB API spec

The data layer is classic but disciplined. Main models: Media, Album (recursive sub-albums via parent_album_id), MediaReaction, Share, PushDevice, AppRelease, User, PendingMediaDigest. Many-to-many between media and album — photos are pointed to, not copied, so the same original can live in multiple albums without duplication.

The most important architectural choice is the access gates. Anything that touches Media or Album goes through app/Policies/MediaAccessGate.php and AlbumAccessGate.php. No direct ->where('user_id', ...) in controllers. When sharing and family-groups expand, you change one method in the policy class — not 20 call sites. The gates honor ancestor shares: if I share a root album, the recipient also sees everything in sub-albums (and their sub-albums) without me having to cascade-share manually. That invariant is locked down with dedicated unit tests in tests/Unit/Policies/.

The service layer is split by domain: Album/AlbumTreeService, Media/{ExifExtractor, ThumbnailGenerator, VideoTranscoder, AlbumCascadeDeletion, MediaFileCleanup, MediaVisibility}, Push/{PushNotificationService, PushPayload}, Realtime/{CentrifugoClient, UploadBurstBroadcaster}, Share/ShareService, Gallery/{ActivityFeedService, OnThisDayService, SidebarComposer}, Storage/StorageStatsService. The later BulkMediaService + BulkAlbumService were extracted in the Sprint 4 review to remove duplication between web and API.

The API surface is 8 controllers + a RedOc viewer at /admin/api-docs. Highlights:

• POST /api/media/check-exists — batch dedup check, throttled at 60/min/user. No client should ever upload a photo the server already has.
• POST /api/auth/login — Sanctum PAT, throttled at 10/min/IP.
• POST /api/devices/register — FCM token persistence per user.
• POST /api/media/reactions — emoji reactions.
• GET /api/photos/with-gps — bbox-filtered lean response for the map view, with an authz scope that honors ancestor shares (again that same gate).
• GET /api/android/version — public auto-update endpoint, with a CRC32 check so the Android app doesn't ask the server if it already has the latest.

Centrifugo is behind a proxy controller that enforces Cookie forwarding (that fixed a debug session of subscribe failures: c40953f infra: forward Cookie header on centrifugo subscribe/publish proxy).

The web gallery — Spec A, B, C and the glass-punk look

The web front is Livewire-heavy, Alpine for the interactive bits, glass-punk tokens lifted from oUTPOSt's Command Center. The layout has a sidebar with a recursive album tree (auto-expand-on-path), a breadcrumb strip, drag-to-reorder, and floating modals.

Spec A — Subfolder UI closed out the hierarchical album model: parent_album_id with cycle prevention (Album::isAncestorOf()), depth cap, RESTRICT-delete if children exist, and an AlbumTreeService that does one BFS walk instead of 20 N+1 queries. Cover inheritance: if a root album doesn't have its own cover, it falls back to descendant media. The sidebar is recursive with a chevron toggle and expanded state derived from the active route.

Spec B — Multi-select + bulk actions. Alpine store for selection state, tile overlays, floating action bar at the bottom of the viewport. BulkDeleteConfirm / BulkMoveModal / BulkAttachModal Livewire modals. Backend: POST /api/media/bulk/{delete,move,attach} + POST /api/albums/bulk/{delete,move} with transactional moves, idempotent multi-album membership, and cycle + depth-cap validation per item. It took 14 commits to get the Alpine transitions to behave — there's an entire sub-theme buried in the commit messages: "transition raced with Alpine dupe", "display-toggle/keyframes race", "opacity-fade (transform-transition races in Chrome)". Final answer: :class is-active CSS toggle. Classic.

Spec C — Right-click context menu. @contextmenu events on album cards, media tiles, sub-album cards. Floating panel mounted in the _modals partial, Alpine.store('contextMenu') handles position-clamping (not flipping — if you right-click near the viewport edge, the menu clamps, it doesn't jump). Glass-punk styling. Smoke tests on HTML render.

The most recent piece to land: 595be36 web fixes: bell-dropdown clipping + media-batch deeplink 404 — the bell icon sits top-right, the panel had left: 0, so it stretched off the right edge of the viewport. Fix: right: 0 so it clips against the right edge instead. Plus a deeplink that pointed at /photos/{id} (doesn't exist) → changed to /gallery/albums/{album_id} (matches AlbumShareReceived's pattern). Small things that make the whole thing cohere.

And as this post is getting hammered out keystroke by keystroke: a665013 spec 2b: profile-page smoke passed — the five-step smoke test of profile tabs, redirects, theme toggle, and device-add reload-fix is green. The profile section also got a pass.

The Android app — from "sync drone" to full client across 3 specs

The scope refinement on 2026-04-23 said Android in MVP is a local gallery browser + auto-sync tool, not a social app. That definition held until Spec D-E-F-G came along and pumped it back up:

Spec D — Media viewer. PhotoViewer with Telephoto zoom + HorizontalPager + auto-hide overlay. VideoPlayer with Media3 ExoPlayer + HLS source via OkHttpDataSource (so Sanctum bearer rides along on HLS segments). Coil 2 ImageLoader Hilt-injected with MemoriaClient.http so images are also authed. MediaViewerRouter dispatches to Photo or Video based on mime_type. Privacy: viewer falls back to thumb/large for non-owned photos (GPS gets stripped on share — it's not enough to just call it a "downscaled JPEG"; the physical byte pipeline does it on the server too).

Spec E — Activity feed redesign. Day-grouped rich cards. NotificationCard as polymorphic dispatcher: type string → specialized MediaBatchCard / ShareCard / GenericCard. MediaBatchUploadedNotification is rolling-aggregated per album per day — so if I upload 50 photos in three batches over 4 hours, my wife gets one notification that updates, not three. RealtimeNotification::mergeable() is an extension point. Composite index on the notifications table for daily-merge lookup. FCM gating respects mute, but the Centrifugo mirror always fires — so the bell counter updates live for muted users.

Spec F — Album-Library. 2-col grid, filter chips (mine/shared/all), pull-to-refresh, drill into sub-albums, separate AlbumDetailScreen with segmented Grid|Map tab. End-to-end smoke test passed 12/12 steps.

Spec G — Maps. This one is the cool one. osmdroid 6.1.20 + osmbonuspack 6.9.0 (JitPack). OpenStreetMap as the tile source (free, no Google Maps API key, no cloud-locked vendor). Custom ClusterRenderer that builds stacked-thumb cluster bitmaps — 1-3 photos overlapping, rotated, with a cyan badge on top. LRU 200-cap so we don't OOM. CustomMarkerClusterer. Cluster tap zooms to the cluster's bbox, animated. PhotoMiniMap integrated in the info sheet (hidden for photos without GPS). PhotoFullMap as a standalone screen + route. AlbumDetail gets a segmented Grid|Map tab scoped to album + descendants. The Photos tab gets the same. Backend serves /api/photos/with-gps with bbox filter, lean response, authz scoped over shares.

GPS preservation on the upload path was non-trivial: Android's MediaStore.Images.Media.EXTERNAL_CONTENT_URI strips GPS by default for privacy reasons unless we call setRequireOriginal() and hold the ACCESS_MEDIA_LOCATION permission. That required an up-front permission check + auto-prompt in MainActivity to make it work without three clicks per session. Spec G fix: ACCESS_MEDIA_LOCATION + setRequireOriginal — preserve GPS-EXIF on upload.

Plus a 4× speedup on sync restart via parallel-hash phase 1, a dedicated HTTP/1.1 client for uploads (HTTP/2 monitor contention with our progress tracker), pause + targeted-retry, and 7 review-fix sprints ("Sprint 7: Test coverage for the band-aid runs" — I love that commit message).

The Windows companion — Mom's part of the project

This one is built with my mom as the primary persona. 75 years old, "minimal tech tolerance". She has to be able to plug her Canon 250D in via USB, or stick an SD card in the card reader, and the photos should just be there on foto.kreden.dk 30 seconds later.

Tech stack: WinUI 3 unpackaged, .NET 9, IHost-based. Solution is split: Memoria.App (UI), Memoria.Core (domain logic, no WinUI deps), Memoria.Api (MemoriaApiClient with login/logout/check-exists), Memoria.Storage (EF Core DbContext + initial migration with the v1 schema). xUnit + AwesomeAssertions 9.4.0 (MIT fork of FluentAssertions, because FA 8 went commercial).

What's already working:

• Tray icon with Open/Exit menu, hide-on-close. Tray-menu Click events didn't work the first time — fix: switch to Command pattern, works now (05cdc8d windows: fix tray-menu Click events not firing — switch to Command pattern).
• Auto-start on Windows login via HKCU Run key + --minimized flag, so it starts invisibly.
• Login dialog + persistent PAT via DPAPI encryption. AppStateStore saves last-known email for pre-fill.
• IHost + Serilog (rolling daily logs + last-session.log for debugging when mom calls).
• DI registration of HttpClient, AuthMessageHandler, MemoriaApiClient, DbContext.
• Migrations run automatically on startup.

Core services (still all under polish):

• IClock + SystemClock + TestClock — so time-based tests can run deterministically without Thread.Sleep.
• AlbumTemplateExpander — expands yyyy-MM-dd, WW-week, HH:mm placeholders so "Summer holiday {yyyy-MM-dd}" becomes "Summer holiday 2026-04-26" at upload time.
• FileFilter — regex per device + glob per folder. Mom has three different scan targets (camera, SD, watched folder); each can have its own filter.
• RetryScheduler — exponential backoff: 1m → 5m → 30m → 2h → daily, max 7 days. If the server is down when photos arrive, the Windows companion doesn't give up before a week has passed.
• DedupService + IServerDedupProbe adapter. The dedup check first does a local SQLite lookup on (camera_serial, datetime_original), then calls the server with batch-exists. Robust against 0001→9999 counter rollover, multi-camera setups, and reformatted cards.

The pipeline has three triggers, same backend: USB camera connected (PTP event), SD card mounted (drive arrival), or file dropped in a watched folder.

Infra — because it has to deploy too

infra/proxmox/create-memoria-lxc.sh provisions the LXC (Debian 12, 6 cores default, 8 GB RAM, dedicated 3TB data disk on raid storage). memoria-provision.sh installs nginx, php-fpm, mariadb, centrifugo, supervisor, exiftool, libvips, ffmpeg. _ctl_memoria.php is the CTL tool in the same style as oUTPOSt's. php artisan memoria:deploy drives the pipeline, and there's a .claude/skills/memoria/ with a deploy skill that knows how to hit the box.

Storage strategy (from the brainstorm):

• /mnt/memoria-data/ — originals, staging, video HLS renditions, mysql backup. Dedicated PVE disk on raid storage.
• /var/lib/memoria/derived/ — thumbnails, web previews. Local LXC disk; throwaway data, can be regenerated.

The Canon RAW pipeline is staging-first: write CR3 to the staging mount → run conversion (thumb + JPG preview + video transcodes) → only after verified successful conversion is the RAW moved to permanent storage. If conversion fails, the RAW stays on staging until an operator intervenes. No data is deleted before there's a guaranteed-playable version.

What I'm proud of

A few things that may seem trivial but are load-bearing:

1. Access gates from day one. When Spec A introduced sub-albums, the sharing inheritance was free: AlbumAccessGate::view honors ancestor shares, Album::scopeVisibleTo includes descendants of shared. Zero controller changes.
2. Batch-exists before upload. Android, Windows and web all hit the same endpoint before they even start streaming bytes. Bandwidth is critical on mobile, and we're not built to throw 1 GB of summer-vacation RAW up the pipe multiple times because sync state went sideways.
3. Metadata preservation is as important as the photo itself. Clients don't re-encode. The server stores raw EXIF as a JSON blob in addition to the structured columns. When the map feature, camera filters, "today X years ago", and lens analytics show up later — they're nearly free.
4. Notification merging. A batch of 50 photos becomes one notification that updates over the day, not a state machine of buzz on the recipient's phone. Mute is respected on FCM, but the bell counter ticks live via Centrifugo. It's the kind of detail that makes this usable for parents, not just developers.
5. Test coverage on the band-aid runs (Sprint 7). When you're doing 90+ commits a day, you accumulate tech debt. Spending an entire sprint just testing what you patched in haste — that's healthy culture.
6. Sub-agent scope discipline. Code review every 5 commits, watch for convention drift. That's what's kept the main architecture clean while we're running ~120 commits/day (memory #1051).

Next up: media map on the web

Android has its map. Web is next. Same /api/photos/with-gps endpoint, same bbox filter, same stacked-thumb cluster aesthetic — but in Leaflet/MapLibre in the browser with a glass-punk overlay and a pulsing wave-grid background.

After that comes shared folders (Spec H?), per-user dashboards (widget grid lifted from Command Center), public share pages with token links and custom themes, and iOS via PWA as an interim. And — I'm not promising anything — maybe face recognition someday, if we feel like maintaining it.

Three days

370+ commits. Three platforms speaking the same batch-dedup API, the same realtime stream, the same metadata contract. An LXC waiting for its first real photo. A Windows tray scanning SD cards. An Android app with a map of every GPS-tagged photo the family has ever taken. A web gallery with right-click menus, drag-to-reorder, hierarchical albums, and a profile page that just passed its smoke test.

It's not done. It's barely started. But this is one of those projects where I think "can it really be three days ago?" and at the same time "can it really be only three days?".

The next post will be punchy. This one was a brick. 🧱
