The servers already matched everything to their agents — we were dropping the
IDs. Now we store them:
- Plex: parse item.guids (imdb://, tmdb://, tvdb://); Jellyfin: parse
item.ProviderIds (added ProviderIds to the requested Fields).
- Stored on movies (tmdb_id, imdb_id), shows (tvdb_id, tmdb_id, imdb_id), and
episodes (tvdb_id) via the upserts.
- Dropped the over-strict UNIQUE on movies.tmdb_id / shows.tvdb_id (same title
can legitimately live in two libraries; we dedupe on server_id). Scanner now
wraps each upsert in try/except so one bad item can't abort a scan.
Tests: guid/ProviderIds parsing + IDs persisted. 38 video-DB/scanner tests green.
- Incremental now does smart early-stopping like music: skips already-known
items and stops after 25 consecutive known (server lists recent first),
instead of a blind fixed cap. Falls back to a full pass when the library is
near-empty (<50), matching music's small-DB behavior.
- Deep scan gains music's 50% safety threshold: if removal would wipe >50% of a
>100-row library, it skips (assumes a partial server response, not a real
emptying) — prevents catastrophic deletion.
- Full Refresh already matched (re-read all, upsert, no removal).
Added DB helpers (server_ids, table_count). Tests: early-stop skips known,
small-lib fallback, 50% prune safety. 122 tests green.
The scan tool now behaves like music's, not just looks like it:
- Card matches: help '?' button, 'Last Scan' line, and the Movies/Shows/
Episodes/Size stats grid (populated from /api/video/dashboard on show + after
a scan). Same .tool-card-stats markup.
- Real progress bar: scanner fetches item totals up front (Plex section.
totalSize / Jellyfin TotalRecordCount) and reports a true percent as it
processes; the bar actually moves (movies → shows) instead of sitting at 100%.
- Cancel: the Scan button toggles to 'Cancel' mid-scan and POSTs
/api/video/scan/stop; the scanner checks a cancel flag between items and ends
in a 'cancelled' state. Mirrors music's stop affordance.
Tests: percent reported, cancel stops midway + saves only processed items, stop
route registered, tool-card structure. 117 video/integrity tests green.
- Paginate Jellyfin movie/series listings (StartIndex/Limit, 500/page) so large
libraries aren't truncated on full/deep scans; incremental stays a single
capped page.
- Per-item try/except in iter_movies/iter_shows (matches Plex) so one bad item
doesn't abort the scan.
- Skip Jellyfin episodes with no IndexNumber (consistency with Plex; avoids
ep-0 collisions). All three modes now solid for Plex + Jellyfin.
The scan no longer blindly grabs every movie/show section — it reads the
libraries you map, like music's 'pick your Music library'.
- GET /api/video/libraries: discover the active server's Movies/TV libraries
(Plex sections by type / Jellyfin views by CollectionType) + current
selection. POST: save {movies, tv} per server into video_settings.
- sources.py: _build_source(movies_lib, tv_lib) filters to the mapped library;
get_active_video_source() (used by the scanner) loads the saved selection;
list_video_libraries() lists them unfiltered for the UI. Falls back to all
libraries when nothing is mapped yet.
- VideoDatabase.get/set_library_selection (per-server). 6 tests added; 33 green.
Plex specials/unmatched episodes can have a null index -> getattr(...,0) still
returned None -> 'NOT NULL constraint failed: episodes.episode_number'.
- Plex adapter skips episodes with no index (logged), passes a real number.
- upsert_show_tree defensively skips any episode missing season/episode number,
so no source can crash a scan. Test added.
The scan inherited the shared client's 15s interactive timeout and fetched
episodes per-season (one request each), so a big library read-timed-out
mid-scan (port 32400).
- Dedicated Plex connection for scans with a 120s timeout (built from the
shared config; doesn't touch the interactive client).
- Fetch a show's episodes in ONE show.episodes() call grouped by season,
instead of seasons()+episodes() per season — far fewer round-trips.
- Per-item try/except in iter_movies/iter_shows so one slow/bad item is skipped
and logged, never aborting the whole scan.
Mirrors the music model (full_refresh vs smart incremental, plus deep_scan):
- incremental: only recently-added items from the server (Plex addedAt:desc /
Jellyfin DateCreated, capped); upsert; no prune.
- full: every item; upsert all (refresh metadata + add new); no prune.
- deep: every item; upsert; prune what the server no longer has (empty-scan
safety preserved).
scanner.request_scan/scan_sync take mode; /api/video/scan/request reads
{mode} from the body (default full); adapters take incremental=. Tests cover
deep-prunes / full-doesn't / empty-deep-safety / incremental-requests-recent.
Reads the active media server and mirrors it into video.db, adapting the music
scan pattern (ask the server, upsert, prune what's gone) — isolated from music.
- core/video/scanner.py: server-agnostic VideoLibraryScanner. Consumes a media
source (duck-typed) yielding normalized dicts; upserts movies + show trees,
prunes removed items, reports progress/state. Skips pruning when a scan
returns nothing (transient-failure safety). Background thread + scan_sync.
- core/video/sources.py: Plex + Jellyfin adapters that REUSE the shared
connected clients (MediaServerEngine) but own all video-section logic; produce
normalized dicts. (Validated against a live server by design; scanner itself
is fully unit-tested with a fake source.)
- api/video/scan.py: POST /api/video/scan/request, GET /api/video/scan/status.
- .gitignore: video_library.db + sidecars (mirrors music); tests inject a
tmp DB so none is ever created in the repo.
Tests: scan populate/prune/empty-safety/no-source-error, isolation guard
(core/video imports nothing from music), scan routes registered. 101 green.
Enrichment matched artists by NAME ONLY (0.85 gate), so for a common name
('Rone' has ~5 artists) it stored whichever the source ranked first — often the
wrong one, which then drove a wrong/sparse library 'Standard' discography while
'Enhanced' (the real owned albums) showed the full set.
Fix — use the decisive signal the library already has (the albums you OWN):
- worker_utils: pick_artist_by_catalog() + catalog_overlap_score() +
owned_album_titles()/release_titles(). When 2+ candidates clear the name gate,
fetch each one's catalog and choose the one overlapping the owned albums; falls
back to the current best-by-name pick when there's nothing to disambiguate or
no overlap (so the common single-candidate path makes no extra API calls).
- Wired into Spotify (covers Spotify-Free, same client), iTunes, Deezer (now
multi-candidate search_artists + get_artist_info store), and MusicBrainz
(match_artist gains owned_titles; release-groups as the catalog).
Re-match path (#868):
- build_reset_query now also clears the stored source-ID column for artist/album
item resets — previously a 're-match' only nulled match_status, so the worker's
existing-id short-circuit re-confirmed the WRONG id and never re-resolved. Tracks
excluded (ids live in tags, not a column).
- MusicBrainz also self-corrects its 90-day name->mbid cache: match_artist bypasses
a cached mbid whose catalog has ZERO overlap with the owned albums, so a re-match
isn't blocked by a stale wrong cache entry.
Tests: shared selector (9), per-worker disambiguation for all 4 sources + MB
backward-compat + MB cache-revalidation (8), reset-clears-id (2). 99 worker/
enrichment tests green.
Four refinements on top of the tiered matcher:
1. Direct source track-ID tier (new top tier): enrichment writes each source's own
track ID into the file tags (spotify_track_id/deezer_track_id/itunes_track_id/...).
If we have the active source's track ID, fetch that exact track by ID via
get_track_details — zero search. Tiers are now: track-ID -> ISRC -> album->track
-> artist+title. _read_file_ids reads ISRC + all per-source IDs in one tag read.
2. Skip already-proposed tracks: a re-run loads existing finding entity_ids for the
job and skips those tracks before any API call (pending stays deduped, dismissed
stays dismissed) — re-runs are cheap.
3. Wrong-version guard: the fuzzy tiers (album-search + track search) reject a
candidate whose length differs from ours by >5s (live/edit/remix with same title).
_load_tracks now selects t.duration; exact tiers (track-ID/ISRC/stored-album-ID)
skip the guard.
4. Tighter album matching: same-title cuts in an album are disambiguated by closest
duration when track_number doesn't decide it.
Findings record matched_via = track_id | isrc | album | search. 30 repair tests pass
(added track-ID tier, duration guard, dedup-skip, and unit coverage).
Replaces the blind fuzzy search with a smart hierarchy that uses the data we
already have, best identity first:
1. ISRC embedded in the file tags (enriched track) -> exact track.
2. Album -> track: use the album's stored source ID (albums.spotify_album_id /
itunes_album_id / deezer_id / musicbrainz_release_id / audiodb_id) when the
ALBUM is enriched (even if the track isn't); else find the album by searching
'artist album', then locate our track in that album's tracklist by normalized
title (track_number breaks ties). Pins the exact album context. (artist->album->track)
3. Plain artist+title search with similarity scoring. (artist->track) — loosest.
_load_tracks now returns dict rows (adds track_number + the album source-id
columns). Findings record matched_via = isrc | album | search. All clients
(spotify/deezer/itunes/discogs) expose search_albums + get_album_tracks with a
uniform {'items': [...]} shape, so the album tier is source-agnostic.
26 repair tests pass (added album-tier + _find_track_in_album coverage).
The job was doing a blind fuzzy search for every low-quality track, ignoring that
enrichment writes each track's ISRC + per-source IDs into the file tags. Now it
reads the file's embedded ISRC and resolves the EXACT track via each source's
'isrc:' search (universal cross-source key), guarded by an ISRC-equality check so
a source that ignores the syntax can't produce a false match — exact track, exact
album context, one call. Falls back to the name/artist fuzzy search only for
un-enriched tracks with no usable ISRC. Findings record matched_via=isrc|search.
4 new seam tests (guard accept/reject, ISRC-preferred-over-fuzzy, fuzzy fallback).
Phase 2 of the redesign. The tool that judged quality by extension and auto-dumped
matches into the wishlist is gone; quality scanning is now the reviewed
quality_upgrade repair job.
Removed:
- Frontend: Tools-page Quality Scanner card, its JS handlers/poller/socket listener,
help tooltip + tour entry (webui index.html, core.js, helper.js, wishlist-tools.js).
- Backend: /api/quality-scanner/{start,status,stop} endpoints, the in-memory state +
executor + 1s socket broadcast, the QualityScannerDeps/run_quality_scanner shim.
- core/discovery/quality_scanner.py: the auto-acting worker + deps class (the shared
match/normalize helpers stay — the new job imports them).
Rewired:
- Automation 'start_quality_scan' action now triggers the quality_upgrade repair job
via repair_worker.run_job_now() (AutomationDeps gains run_repair_job_now, drops the
4 scanner fields). Action block's vestigial scope field removed (scope lives in the
job's settings now). NOTE: the 'quality_scan_completed' trigger no longer fires (the
repair job doesn't emit it).
- Updated all automation test _build_deps helpers + conftest tool-progress harness;
deleted the obsolete worker test. 528 affected tests pass; 6123 collect cleanly.
QUALITY_TIERS / _get_quality_tier_from_extension kept (used elsewhere).
The old Quality Scanner tool judged quality by file EXTENSION only (a 128k and a
320k MP3 looked identical), ignored the bitrate-based quality profile, used min()
of enabled tiers so the default profile flagged the ENTIRE non-lossless library,
and auto-dumped every match into the wishlist with no review.
This new repair job does it properly:
- meets_preferred_quality(): pure, bitrate-AWARE decision honoring every enabled
quality bucket (320 MP3 passes a FLAC+320+256 profile; 128 MP3 doesn't). Floor
is the worst enabled bucket, not the best.
- scans watchlist artists or whole library, finds below-quality tracks, matches a
better version at scan time (reusing the existing tested match helpers), emits a
FINDING showing the match + confidence. Off by default; nothing auto-queued.
- _fix_quality_upgrade apply handler adds the matched track WITH album context to
the wishlist — the user-approved version of what the old tool did silently.
- Transcode/fake-lossless detection intentionally left to the existing Fake
Lossless Detector job.
12 seam tests incl. a regression pinning the default-profile flooding bug. The old
tool is still in place; removing it + rewiring its automation action is the next step.
Two issues in the same path:
1. The shared discovery modal pre-renders one row per track from a
separately-fetched frontend track list, then the poll dropped any backend
result without a pre-rendered row (if (!row) return). When the frontend's
track fetch came back rate-limited/partial (~21) while discovery's own fetch
got all 59, the surplus results vanished. Now the modal CREATES a row for any
result lacking one, so authoritative backend results drive the list (fixes
all sources sharing the modal).
2. get_playlist hydrated a whole relationships page in one _get_tracks_batch
call, but Tidal caps filter[id] at 20/request, silently truncating larger
pages. Chunk to the cap like get_album_tracks already does.
Seam + regression tests (tests/test_tidal_playlist_batch_chunking.py).
Status checks asked is_spotify_authenticated() (official OAuth only) instead of
is_spotify_metadata_available(), so a Spotify-Free primary read as disconnected.
get_primary_source_status had spotify_free awareness but it was dead code:
get_client_for_source('spotify') returns None unless officially authed, so the
free-availability probe never had a client. Fetch the client directly for that
check; add the missing free branch to the dashboard test message. Seam + regression tests.
The reconcile read each completed task's final_file_path to find paths — but not
every import path sets it (the verification worker marks the task completed
without it), so tracks that imported via that path were silently dropped (user
saw 3 of 5 symlinks). Root cause: leaning on a fragile per-task field.
Now reconcile_batch_playlists identifies the organize playlists the batch touched
(its own + any reached via a completed track's source_info provenance) and
rebuilds each from CURRENT library ownership via _rebuild_one_from_db
(check_track_exists over membership). It just asks the library what's owned, so
it's robust to HOW a track imported (modal worker / slskd monitor / verification
worker) and still prunes tracks that left. Takes a db handle; all three callers
pass MusicDatabase().
Reconcile tests rewritten for the DB-rebuild form (organize batch, wishlist
provenance, non-organize skip, plain no-op). 973 downloads/imports/playlist
tests pass.
on_download_completed and check_batch_completion_v2 are duplicate completion
paths. Monitor-detected downloads (Deezer / slskd-monitor / verification-worker
imports) finish the batch via the V2 path, but the materialize reconcile was
only added to on_download_completed — so those batches never built playlist
folders (no '[Playlist Folder] Rebuilt' line at all). Add the same non-fatal
reconcile to the V2 path. Now all three completion points (both lifecycle paths
+ the master.py all-owned path) materialize. 550 tests pass.
Symmetric to the post-download reconcile (which handles ADDITIONS): when a
playlist's membership is re-synced (the mirror step — scheduled refresh or the
manual mirror endpoint), rebuild its folder from current membership WITH prune
IF it's organize-by-playlist. So a track that just LEFT the playlist has its
symlink cleaned up the instant membership changes, not only on the next download.
Factored a shared _rebuild_one_from_db (used by the manual 'Rebuild' button and
the mirror hook) + rebuild_mirrored_playlist_if_organized. Gated to organized
playlists, non-fatal at both mirror call sites.
Now the invariant 'folder = the playlist's current owned members' holds on every
change: additions caught at download, removals caught at mirror. 2 new tests
(removed track pruned; non-organized skipped). 985 + 277 tests pass.
Replaces the two organize-only triggers with a single reconcile_batch_playlists
called at both batch-completion points. It groups the batch's newly-resolved
tracks by their per-track playlist provenance:
- the batch's OWN organize playlist → full (re)build with prune, and
- a track that completed for a DIFFERENT playlist (e.g. a WISHLIST fulfilling a
track that belongs to an organize playlist) → ADDED to that folder, no prune.
So a late wishlist arrival now lands in its playlist folder immediately, instead
of only on the next sync/manual rebuild — the folder = the playlist's owned
members, kept true on every ownership change regardless of download path. Uses
the paths the batch already captured (no DB re-match, no waiting on the server
scan/sync). Non-fatal.
3 new reconcile tests (organize full-rebuild, wishlist add-without-prune, plain
batch no-op). 983 downloads/imports/playlist tests pass.
- Settings: 'Playlists Folder' path field (Unlock pattern, separate-root help
text), a Symlinks/Copies selector, and a 'Rebuild playlist folders now' button
(standard test-button style). Wired through PATH_INPUT_IDS / load / save, plus
'playlists' added to the settings save allowlist so it persists.
- POST /api/playlists/materialize/rebuild → rebuild_organized_playlists_from_db:
rebuilds every organize-by-playlist folder from CURRENT ownership, re-matching
each track with check_track_exists (name, not IDs) so it self-heals after a
reorganize / membership change. +1 test.
70 materialize tests + JS integrity pass; settings round-trip wiring verified.
- Routing (step 5): organize-by-playlist tracks no longer set the per-track
_playlist_folder_mode flag, so they import NORMALLY into Artist/Album — exactly
what a normal download does. _playlist_name provenance is kept (origin.py).
- Triggers (step 4): build the playlist folder from the batch's own payload at
both end-of-flow points — the all-owned path in master.py (no downloads, so the
lifecycle never runs) and the batch-complete hook in lifecycle.py (after
downloads). Both gated on playlist_folder_mode, both non-fatal.
Works for the all-owned case (the smack test that did nothing before) and for
mixed owned/downloaded, with no source-ID or mirrored-playlist dependency. The
materialized folder uses the default ./Playlists root + symlink mode until the
Settings UI is added.
Updated the master test to assert the new contract (provenance kept, routing
flag gone). 979 tests pass.
materialize_playlist_from_batch(batch, download_tasks, config) collects the real
on-disk path of every resolved track from the batch's OWN payload — owned via
analysis_results.matched_file_path, downloaded via tasks.final_file_path — runs
each through the playback path resolver (Docker-correct), de-dupes, and hands the
list to rebuild_playlist_folder. Gated on playlist_folder_mode.
No re-matching, no source IDs, no mirrored-playlist lookup — works for any
organize-by-playlist download including the all-owned case. 5 tests. Still
isolated; the triggers wire it in next.
- settings: playlists.materialize_path (separate root, mapped apart from the
music library so the media server never double-scans it) + materialize_mode
(symlink|copy).
- core/playlists/materialize.py: pure filesystem engine that (re)builds a
playlist folder of relative symlinks (or copies) into the real library —
idempotent, prunes stale entries, disambiguates filename collisions, never
escapes the root, and auto-falls-back to copy when the FS can't symlink.
No DB, no app state; ops injectable. 13 unit tests.
Isolated + additive — nothing live calls this yet (stitcher/trigger/routing
come next).
The download analysis already matches every track to a library row via
check_track_exists / manual match, then discarded the result. Keep it: each
analysis_results entry now carries matched_file_path + matched_track_id (the
owned file's real location, or None). Symmetrically, a completed download task
now records final_file_path (where the import landed).
Purely additive, no behavior change, no new matching, zero perf cost — just
stops throwing away what the pipeline already computed. This is the foundation
for playlist materialization: owned + downloaded tracks both report where their
real file is, so the folder can be built by name match, not source IDs.
A DB<->filesystem path mismatch (Docker volume change, remount, Music
Paths unset for the container) makes EVERY library file fail to resolve
to a DB track, so the orphan detector flags the whole library as
orphaned. The mass-orphan check only logged a warning and then created
the findings anyway — so a user batch-applying 'move to staging' or
'delete' would relocate or wipe their entire library.
Make it a hard skip (create zero findings) like the dead-file cleaner
and stale-removal paths already do (#828). Centralise the predicate as
is_implausible_orphan_flood() alongside is_implausible_stale_removal()
so the rule lives in one tested place. Small genuine orphan sets still
surface unchanged — only an implausibly large flood (>50% and >20) is
suppressed.
Tests: seam cases for the new predicate + scan-level regressions (mass
mismatch -> 0 findings; small genuine set -> still reported).
Extends the watchlist export to the full library. The exporter is now general
(core/exports/artist_export.py, renamed from watchlist_export) — adds tidal/qobuz
links and an extra_fields passthrough, so the library export also carries
lastfm/genius URLs + soul_id, and an optional "library counts" toggle adds owned
album/track counts per artist.
- GET /api/library/artists/export?format=&links=&contents= — pulls every artists
row, normalizes onto the canonical *_artist_id keys, optionally GROUP-BY counts
for album/track totals.
- The export modal is now openArtistExportModal(scope): "Export Library" button in
the library header + the existing "Export" on the watchlist bar (a thin wrapper).
Library mode shows the extra "library counts" toggle.
Tests (11): builder across formats + the new tidal/qobuz links + extra_fields
columns; watchlist + library endpoint wiring. 64 integrity green; ruff clean.
An "Export" button on the watchlist filter bar opens a modal (same aesthetic as the
artist DB-record inspector) to export your whole watchlist roster — each artist's
name + source IDs (spotify / musicbrainz / deezer / discogs / itunes / amazon),
with an optional "external links" toggle that adds the discography URLs built from
those IDs. Live preview, copy, and download in the chosen format.
- core/exports/watchlist_export.py: pure builder (json/csv/txt + links, present-IDs
only, deterministic columns) — the single source of truth, fully unit-tested.
- GET /api/watchlist/export?format=&links= shapes the roster + returns it (with
X-Export-Count / X-Export-Ext headers for the modal).
- Frontend reuses the DB-record helpers (_jsonSyntaxHighlight / _arecCopy).
Tests (8): builder across json/csv/txt, links on/off, present-ids-only, empty +
bad-format fallback, mime/ext, and endpoint wiring. ruff clean; 64 integrity green.
Scoped to the watchlist for v1; library-wide export + a "library contents"
(owned albums/tracks) option are natural follow-ups.
New Aria2 JSON-RPC adapter, alongside qBittorrent / Transmission / Deluge. Aria2's
RPC (default :6800/jsonrpc) maps cleanly onto the uniform adapter contract:
- the --rpc-secret token leads every call as "token:<secret>" (no username — the
secret uses the existing password field),
- addUri returns a GID (our torrent id); tellStatus → TorrentStatus with state
mapping (active→downloading, or seeding once the payload is complete; waiting→
queued; etc.),
- remove picks forceRemove vs removeDownloadResult by status, and (since aria2
doesn't delete files on remove) unlinks the file paths itself for delete_files,
- bare-host URLs get /jsonrpc appended.
Wired into adapter_for_type + the Settings dropdown (with a help note: port 6800,
secret in the Password field). All adapter methods go through the same interface,
so the stall/orphan handling and downloads pipeline work unchanged.
Tests (9): registry wiring, state mapping (incl. active→seeding), token-prefixed
params, /jsonrpc fixup, status parse (+ name fallback, no div-by-zero). 126 torrent
tests green; ruff clean.
A maintenance job to keep the music library tidy — finds empty folders left behind
by imports/relocations/deletions (empty artist/album dirs, or dirs holding only OS
junk like .DS_Store/Thumbs.db) and removes them.
Safety is the focus (deleting directories is destructive):
- only TRULY empty folders are flagged — a folder with a cover image or any audio
is never touched; only OS-junk files count as "no real content" (a setting),
- the library root + symlinked dirs are never removed,
- walks bottom-up so a parent left empty by its removable children cascades,
- the apply handler RE-CHECKS emptiness at delete time, so a folder that gained a
file between scan and apply is left alone.
dir_is_removable + remove_empty_folder are pure/injectable seams. Wired through the
job registry, repair_worker apply handler (_fix_empty_folder), fixable-types, and
the findings UI. Opt-in (default off), weekly interval.
Tests (10): removable decision (empty / real-file / surviving-subdir / junk-only /
strict mode) + apply re-check (removes empty + junk, refuses content/root/symlink).
Repair + integrity suites green; ruff clean.
A transient ping failure (network blip, Navidrome busy mid-scan) makes
_setup_client null out the configured creds, and _connection_attempted then
latches the client "disconnected" — so is_connected() returned False forever until
the user hit the manual Test button to re-read config. That's the reported
"disconnects every 5-10 min, reconnects instantly on Test."
Fix: ensure_connection no longer latches on a failed attempt — once a short
throttle (_RECONNECT_THROTTLE_S = 20s) elapses it re-attempts, and is_connected()
triggers that retry whenever it's currently disconnected. So a blip recovers on its
own within the next status check, no manual reconnect. The throttle prevents ping
storms when Navidrome is genuinely down.
Tests: transient failure self-heals after the throttle (and doesn't re-ping within
it); a connected client never re-pings; first connect attempts once. 115 navidrome/
media-server tests green.
Invariant: while security.require_login is on, every profile must have a login
password or it's locked out. Previously only the admin's own anti-lockout existed,
so members could be stranded (created without a password, or login flipped on while
passwordless members existed). Closed all the write-points:
core/security/login_provisioning.py (pure policy, single source of truth):
- members_without_password(profiles) — non-admin profiles that can't sign in
- create_needs_password(require_login) / removing_password_strands(require_login)
Wired into web_server:
- create_profile: while login is on, a new member must be given a password (400
otherwise) and it's set on creation.
- enable-login (settings save): refuses to turn login on while any member lacks a
password — lists them — same shape as the existing admin anti-lockout.
- set-password: refuses to CLEAR a password while login is on (would strand them).
UI: Create Profile form gains a login-password field (alongside the optional PIN);
the Manage Profiles per-member password button (prior commit) covers existing
members + changes.
Tests: pure policy seam + endpoint enforcement (create blocked w/o password when
on, allowed w/ password, no friction when off, clear blocked when on). 442
profile/settings/auth tests green; ruff clean.
