Adds a new Map sidebar entry that plots photos by their EXIF GPS
coordinates on a clustered Leaflet map. While wiring this up, the
metadata extractor was reading unprefixed GPS keys that never exist
in `exiftool -G -j` output AND assumed coordinates were already
floats — every photo silently lost its GPS. The new extract_gps
helper handles Composite/EXIF group prefixes and parses DMS strings,
and lat/lon are stored as first-class indexed columns so the map
can query them without parsing exif_json on every request.

The Duplicates section was useless: SHA-256-only detection only caught
byte-identical files, not the actual duplicates a real library
accumulates (re-encoded JPEGs, screenshots, resized exports), and the
view was a flat date-sorted list with no grouping or actions. This
replaces the whole flow.
Detection
- New phash + duplicate_group_id columns on Photo, added via an
idempotent ALTER TABLE pass in init_db (the project has no Alembic).
- Thumbs worker computes a 64-bit pHash from the original-resolution
decoded frame just before the destructive thumbnail loop. Falls back
silently — phash is nice-to-have, not a blocker for thumbnails.
- backfill_phashes Celery task fills in phashes for photos that
predated the column, reading the existing thumb_large rather than
re-decoding the original.
- regroup_duplicates service runs union-find over Hamming distance
(threshold 6), persists duplicate_group_id, and maintains is_duplicate
as derived state so existing badges/counts keep working. Chained
after scan_all_source_roots with a 60s countdown.
API
- GET /library/duplicates/groups returns all groups with members,
bucketed in Python from one query. Each group has a reason ("exact"
iff every member shares a SHA-256, "similar" otherwise).
- POST /library/maintenance/{regroup-duplicates,backfill-phashes}.
Frontend
- New DuplicatesView (sectioned grid, one section per cluster) replaces
the timeline when the user is in the duplicates section. Each section
shows a "Keep best, discard N" button that picks the highest-pixel
copy and reuses the existing undoable bulk-discard so Cmd+Z works.
- Manual best override: hover any non-best thumbnail and click "Keep
this" (Crown icon, top-right) to override the auto-pick. The header
annotates "(manual)" so it's obvious which copy will be kept.
- Keyboard nav within the duplicates view walks the flat member list,
with ↑/↓ jumping by the measured column count and scrollIntoView on
every move. Timeline's keyboard handler now early-returns in the
duplicates section so the two don't fight.
- BEST pill / Keep-this button live at top-right with a ring outline so
they don't collide visually with the cyan selection ring around a
selected cell. Dimensions chip moved to bottom-left to free both
right corners for the keep affordances.
- New "Duplicates" section in SettingsDialog: shows group/member counts
and exposes both backfill + re-detect actions, sharing a query cache
with DuplicatesView via DUPLICATE_GROUPS_QUERY_KEY.
- PhotoInfoPanel "Basic Info" section now shows the photo's full file
path in monospace below the size/dimensions/date grid.
- New imagehash==4.3.1 dep in requirements.txt.

prune_missing_photos() previously only deleted Photo rows whose files
were gone, leaving every folder row from the old library in the DB —
which made the sidebar tree wildly out of sync with the on-disk
structure (still showing /photos/2024/, /photos/2026/03/, etc. that
no longer exist).
Now also drops Folder rows whose path doesn't resolve under a mounted
source root, with the same defensive "skip if source root unmounted"
guard. The Settings orphan card surfaces both counts.

Adds /api/v1/library/maintenance/{missing-stats,prune-missing} backed
by a new cleanup helper that deletes Photo rows whose files no longer
exist on disk under a *mounted* source root. Skips photos under
unmounted roots so a temporarily-disconnected drive doesn't get
silently nuked.
Settings panel surfaces the orphan count with a destructive Prune
button, plus a "Kick pending" action that re-queues photos stuck in
processing_status='pending' (typically left behind when the scanner
created the row but the worker never picked up the thumbnail task).
Common trigger: PHOTO_DIRS in .env was repointed at a different
library root, leaving every old row dangling.

Diagnosis: every backend restart was dispatching watch_folders.delay()
unconditionally. watch_folders is an infinite-loop celery task
(for changes in watch(*paths)). With CELERYD_CONCURRENCY=4 and several
restarts during dev, all four worker slots ended up pinned by stale
watch_folders instances, leaving zero workers free for scan_folder.
The result: clicking "Scan all folders" successfully queued a task
that then sat in the queue forever, the new /photos/sub folder was
never walked, and the user's newly added photo never appeared.
The watcher was only opportunistically useful and the user already
triggers scans manually. Disabling it removes the foot-gun. Re-
enabling needs:
- a Redis lock so only one watcher runs at a time
- or a dedicated long-running container with concurrency=1
- or a celery beat schedule with a singleton flag
Until then, manual scans work. Cleared the backlog by wiping the
redis broker volume so the stale watch_folders tasks are gone.
Verified: post-fix, scan_folder runs in 0.12s and reports
"Processed 7/7 files. Errors: 0", picking up the previously missing
/photos/sub/Samuel_Colman... file.

The frontend AddSourceFolderDialog let users register source roots
from inside the app, but with the bootstrap auto-creating one for
the /photos mount on first boot, the dialog was redundant in the
common case and confusing in every other (users had to know which
container path corresponded to their host directory). Going
config-driven matches Plex/Photoprism/Immich and matches the
mental model "the docker mount IS the library".
Frontend
- Deleted components/dialogs/AddSourceFolderDialog.tsx entirely.
- LeftSidebar drops the "+ Add Source Folder" button + bottom-bar
layout, the addFolderMutation, the dead Plus action button on
the (no-longer-existing) folders/heaps tree headers, and the
Plus icon import.
- api.ts: removed sourceFolders.add(), library.browse(), and the
BrowseChild / BrowseResponse types. The remaining sourceFolders
surface is read-only (list + manual scan).
- LeftSidebar bottom strip is now just the "Scan all folders"
button when there's at least one source root.
Backend
- Dropped POST /folders (no consumers) along with FolderCreate /
FolderResponse pydantic models. The folders router header now
documents the config-driven approach.
- Dropped GET /library/browse (no consumers). Removed the unused
os/HTTPException/SourceRoot imports it brought in.
- cleanup_data_integrity now also walks the source roots and logs
a warning for any whose path is missing on disk. Doesn't auto-
delete (a missing path could be a temporarily unmounted drive)
but surfaces enough hint to fix it. Returns the count in the
summary dict alongside merged-duplicates.
Docs
- README "How libraries are managed" section rewritten to spell
out that mounts ARE source roots, edit .env + restart, no UI for
managing source roots. New "Changing or adding libraries"
section walks through the typical edit-restart loop including
the optional volume-nuke for a clean slate.
- "Adding more libraries" subsection covers multi-mount via
edited compose with a note that auto-registration is roadmap.

Cleans up the maze of overlapping ways folders entered the app, plus
removes the dead trash plumbing left over from the soft-discard
refactor.
Setup model (now)
- ONE env var: PHOTO_DIRS in .env, set to the host path of your
library. Compose mounts that at /photos. That's the entire setup.
- On first boot, the backend auto-creates a SourceRoot row named
"Library" pointing at /photos so the user sees their photos
immediately without configuring anything.
- Source roots and discard live in the database; mulita.yml only
carries operational settings (thumbnails, scanner, performance).
- The "Add Source Folder" dialog is now a directory browser
restricted server-side to /photos and any existing source root —
the user clicks through actual mounted directories instead of
typing container paths they can't possibly know.
Backend
- New services/scanner.bootstrap_default_source_root(): if no
SourceRoot rows exist and /photos is mounted, create one. Wired
into the lifespan handler before cleanup + initial scan.
- New GET /library/browse?path= returning the immediate child
directories of `path`, validated to live under one of the allowed
roots (default mount + every active SourceRoot). Hidden entries
are filtered. Children are tagged with is_existing_root so the UI
can show an "Added" badge. Returns parent path for up-nav, or
null when at the top of the allowed scope.
- scan_all_source_roots now reads from the DB instead of the YAML
config so DB-managed source roots are honoured by initial scan.
- Dropped the placeholder source_roots block from mulita.yml — the
paths /photos/main and /photos/iphone never existed and just
produced startup warnings.
- Dropped TrashSettings, settings.trash, settings.source_roots,
and the SourceRoot pydantic model from config.py. Soft discard
has owned this for a while; it was dead code.
Compose
- Single ${PHOTO_DIRS:-./photos}:/photos:rw mount in both backend
and worker.
- Removed the hardcoded ~/Pictures:/host/Pictures:rw mount — the
PHOTO_DIRS variable is the single source of truth now.
- Removed the trash_data named volume + mounts (no consumers).
- backend/Dockerfile no longer creates /data/trash; it now creates
/data/proxies (which the proxy endpoint actually uses).
Frontend
- AddSourceFolderDialog rewritten as a directory tree picker:
loads /library/browse on open, lets the user navigate up via a
ChevronUp button or down by clicking subfolders, shows the
current path inline, and adds whatever directory is currently
shown. Existing source roots are tagged "Added" so the user
knows what's already registered. Errors from the backend (e.g.
trying to navigate outside the allowed scope) surface inline.
- New library.browse() helper + BrowseChild / BrowseResponse types
in services/api.ts.
Docs
- README Quick Start rewritten around the single PHOTO_DIRS env
var, with macOS/Linux/Windows examples.
- New "How mounted folders and source folders relate" section that
spells out the two-layer model (mount = visibility, source root
= scanning) so the most common confusion is addressed up front.
- Added a "Read-only libraries" subsection that lists exactly which
endpoints fail under :ro.
- "Configuration" section reframed: source roots are managed by the
UI/API now, mulita.yml is operational settings only.
- .env file now has examples for the common host paths.

Two related fixes:
1. Prevention — scanner now normalizes paths before lookup/insert
in get_or_create_source_root and get_or_create_folder. Trailing
slashes, redundant separators, and `.` segments all collapse to
the same row. _normalize_path uses os.path.normpath; symlinks
are intentionally NOT resolved so mount paths stay intact for
cross-machine portability.
2. Cleanup — new app/services/cleanup.py runs on backend startup
(idempotent) and merges any pre-existing duplicates left over
from older scanner versions:
- Groups source_roots by normalized path. Picks the canonical
row (preferring one with a non-empty name and the earliest
added_at), re-points child Folder rows via UPDATE, and
deletes the duplicates.
- Same for folders, with photo_count as the tiebreaker. Photos
get re-pointed to the canonical folder via UPDATE.
- Recomputes folder.photo_count from the actual non-discarded
photo membership so the sidebar count matches reality.
Wired into main.py's lifespan handler. On the dev DB this merged
the empty-name "/host/Pictures/MulitaTest/" duplicate that was
showing up alongside the canonical MulitaTest source root.
