Frank Stellmacher 9fa086c428 feat(server): dual server address (LAN + public) per profile (#880)
* feat(server): ServerProfile.alternateUrl + shareUsesLocalUrl

Additive optional fields on ServerProfile to back the dual-address work.
'alternateUrl' is the optional second endpoint (e.g. LAN counterpart of a
public 'url' or vice versa); 'shareUsesLocalUrl' chooses which of the two
goes into Orbit / entity / magic-string shares when both are set.

Pure schema change — no runtime consumers yet. Single-address profiles
keep the same persisted shape; the optional fields are simply absent.

* feat(server): serverEndpoint module with LAN classification + IPv6

Introduces a single home for connect-/share-layer URL utilities that
the dual-address work will build on:

  * normalizeServerBaseUrl(raw) — aligned with serverProfileBaseUrl
  * isLanUrl(url) — IPv4 (unchanged) + IPv6: ::1 loopback, fe80::/10
    link-local, fc00::/7 ULA, and IPv4-mapped (both dot-decimal and the
    URL-API-normalized hex form, since new URL() rewrites ::ffff:1.2.3.4
    to ::ffff:HHHH:HHHH)
  * allNormalizedAddresses(profile) — deduped [url, alternateUrl?]
  * serverAddressEndpoints(profile) — LAN-first ServerEndpoint[]

isLanUrl moves out of useConnectionStatus.ts (the hook now imports +
re-exports it for backward compatibility); OrbitStartModal points at
the new path directly. 38 unit tests cover the IPv4/IPv6 matrix,
dedupe, ordering, and edge cases.

* feat(server): pickReachableBaseUrl with in-memory connect cache

Adds the runtime connect layer on top of serverEndpoint:

  * pickReachableBaseUrl(profile) — sequential LAN-first ping via the
    existing pingWithCredentials; first OK wins.
  * ensureConnectUrlResolved(profile) — boot / switch / online-event
    entry point (same mechanism, intent-named).
  * In-memory cache keyed by profileId; sticky behaviour tries the
    cached endpoint first, falls back to the natural order on miss.
  * invalidateReachableEndpointCache(profileId?) — single-profile and
    whole-cache flushes for profile-edit / credentials-change / online.
  * getCachedConnectBaseUrl(profileId) — sync getter for getBaseUrl
    fallback path (next commit).

The cache is **session-only**, never persisted. Single-address profiles
keep the same shape (one endpoint, one ping). 9 new unit tests cover
single + dual address, LAN-first preference, fallthrough, unreachable +
stale-cache clear, sticky hit, and the two invalidate flavours.

* feat(server): getBaseUrl reads connect cache, falls back to primary url

Dual-address profiles need 'getBaseUrl' to return the runtime-probed
connect URL (LAN at home, public elsewhere), not the literal primary
'url'. To keep the sync getter shape that ~60 call sites depend on,
the store now reads 'getCachedConnectBaseUrl(server.id)' from the
serverEndpoint cache.

If no probe has run yet (very early boot, before switchActiveServer
populates the cache), it falls back to the normalized primary URL —
identical to today's behaviour. Single-address profiles see no
difference; their cache entry equals serverProfileBaseUrl(url).

* feat(server): switch + connection-status probe via ensureConnectUrlResolved

Both surfaces that previously called pingWithCredentials(server.url, ...)
directly now route through the dual-address connect layer:

  * switchActiveServer awaits ensureConnectUrlResolved(server), reads the
    identity (type/serverVersion/openSubsonic) off the returned ping, and
    hands probe.baseUrl (not server.url) to scheduleInstantMixProbeForServer
    so the AudioMuse probe also hits the reachable endpoint.
  * useConnectionStatus.check() does the same on every 120 s tick — sticky
    cache fast-paths the steady state, and a network change naturally
    flips the active endpoint without a manual retry.
  * useConnectionStatus.retry() and the 'online' event flush the cached
    entry for the active profile first, so the next probe starts from the
    natural LAN-first order instead of revalidating a stale URL.

Single-address profiles behave identically: one endpoint in the list,
one ping per check. No behaviour change for them.

* feat(server): PickReachableResult.ping + connectBaseUrlForServer helper

Two additive extensions to the serverEndpoint surface that the upcoming
CONNECT migrations all need:

  * 'ping: PingWithCredentialsResult' on the OK branch of
    PickReachableResult so callers (switchActiveServer,
    useConnectionStatus) can read type/serverVersion/openSubsonic from
    the same probe instead of issuing a second pingWithCredentials.
  * connectBaseUrlForServer(server) — sync getter for the connect URL
    of *any* saved profile (active or not). Reads the cache, falls back
    to normalized primary url on miss. Becomes the canonical helper
    for non-active-server HTTP traffic (apiForServer, stream URLs,
    cover fetches, library bind session).

Tests: pingOk() fixture now returns identity fields; the single
toEqual-asserting test in pickReachableBaseUrl became a guarded read
to keep equality concise while still asserting on the new ping field.

* feat(connect): apiForServer + stream URLs route via connectBaseUrlForServer

Non-active-server HTTP traffic (the apiForServer entry point, used by
QueuePanel cross-server cover fetches and share-paste resolution) and
the stream-URL builders previously read 'server.url' directly,
bypassing the dual-address connect cache. Both now go through
connectBaseUrlForServer, which serves the cached LAN/public endpoint
when one exists and falls back to the normalized primary url
otherwise.

buildStreamUrl(id) now uses the baseUrl it already pulled from
getBaseUrl() (which is connect-cache aware as of 2a6d8283) instead of
re-normalizing server.url — same value for single-address profiles,
correctly dual-address for the rest. Single-address callers see no
behaviour change.

* feat(connect): cover fetch + cover-cache ensure use connect URL

Both cover-fetch surfaces previously read 'scope.url' / 'server.url'
straight into HTTP requests, which would freeze the cover pipeline on
the primary URL even when a LAN endpoint was reachable:

  * buildCoverArtFetchUrl(ref, tier) — for the 'server' scope (queue
    rows cached against a non-active profile) and the 'playback' scope
    (cross-server playback) now resolves the connect URL via
    connectBaseUrlForServer before handing off to
    buildCoverArtUrlForServer.
  * ensureArgsFromRef in coverCache.ts — restBaseUrl for the Tauri
    'cover_cache_ensure' invoke now uses the cached connect URL for
    both 'server' and 'active'/'playback' scopes.

Scope.url itself remains the index-stable primary URL — that's what
storageKeys (INDEX) consume. Only the HTTP base shifts to the connect
endpoint, exactly the split the spec calls out.

* feat(connect): library bind + server-test probe via ensureConnectUrlResolved

Two more 'rebind / re-test an existing saved server' paths still pinged
the literal primary URL — both go through the dual-address connect
layer now:

  * bindIndexedServer (librarySession.ts): used to ping server.url then
    pass serverProfileBaseUrl(server) as the bind 'baseUrl' to Rust.
    Now: one ensureConnectUrlResolved call covers both — probe.baseUrl
    feeds librarySyncBindSession directly, so Rust's per-server library
    sync uses whichever endpoint actually answered. Drops the
    pingWithCredentials and serverProfileBaseUrl imports.
  * testConnection (ServersTab.tsx): same shape — probe via the connect
    layer, read identity from probe.ping, hand probe.baseUrl to
    scheduleInstantMixProbeForServer so the AudioMuse probe also hits
    the connect endpoint. Single-address profiles still ping once.

Add/edit save handlers (handleAddServer / handleEditServer) keep the
direct pingWithCredentials against the user-entered data.url — that
flow is the dual-address verify hook, which PR 2 extends.

* feat(server): serverShareBaseUrl — public-by-default share URL picker

Adds the share-layer companion to connectBaseUrlForServer. Different
intent: connect picks the reachable endpoint for HTTP, share picks the
URL that goes into Orbit invites / entity share payloads / queue share
links / magic strings — where a guest opening the link is not on the
host's LAN.

Logic per spec §5.1:
  * Single-address profile → that one address (normalized).
  * Both set, default flag → public.
  * Both set, shareUsesLocalUrl flag → local.
  * Edge cases (both LAN, both public, missing one of the two): fall
    back to the first endpoint in the list so the function is total.

Empty profile returns the normalized url (possibly empty) — defensive,
never throws. 7 unit tests pin all six branches plus the empty case.

Call-site migration (Orbit, copyEntityShareLink, QueuePanel, magic
string srv field, findServerIdForShareUrl, Orbit LAN warning) lands
in the next commits.

* feat(share): Orbit + entity + queue shares use serverShareBaseUrl

Four share-encoding surfaces previously read 'getBaseUrl()' (connect)
or the raw 'server.url' (primary) when embedding the host into outgoing
share links — both wrong for a dual-address profile:

  * copyEntityShareLink (track / album / artist / composer) — was
    getBaseUrl(); now reads serverShareBaseUrl(active). Guests opening
    the link are off-LAN, so public is the right default.
  * OrbitStartModal — was raw server?.url for both 'buildOrbitShareLink'
    and the LAN warning. Now goes through serverShareBaseUrl; the LAN
    warning correspondingly reflects the address the guest will see,
    not the host's primary.
  * OrbitSharePopover — same fix on the host-only share popover.
  * QueuePanel.handleCopyQueueShare — was getBaseUrl(); same migration.

Single-address profiles return exactly the same string from
serverShareBaseUrl as serverProfileBaseUrl(server.url) did before, so
no behaviour change for the common case. shareUsesLocalUrl flips the
default to LAN for the rare 'share into a LAN-only group' use; that
checkbox lands with the form UI in the next sub-phase.

findServerIdForShareUrl + paste-side share matchers are migrated in
the next commit (read-side of the same contract).

* feat(share): paste-side resolves dual-address profiles + connect URL

Read-side counterpart to the encode-side migration:

  * findServerIdForShareUrl(servers, shareSrv) now matches a profile
    when shareSrv normalizes to either profile.url OR profile.alternateUrl.
    Without this, a paste of a link generated against the host's LAN
    address (shareUsesLocalUrl=true) would fail to find the local saved
    profile even though it's the same server.
  * resolveSharedSong / resolveShareSearchAlbum / resolveShareSearchArtist
    in enqueueShareSearchPayload now hand connectBaseUrlForServer(lookup.server)
    to the *WithCredentials HTTP calls instead of the raw lookup.server.url.
    The looked-up profile may be dual-address; this routes the song / album /
    artist fetch through whichever endpoint is currently reachable.

Indirect consumers (shareServerOriginLabel, shareQueueServerContext) read
the same findServerIdForShareUrl, so no code change needed there — they
now match both addresses transparently.

* feat(verify): serverFingerprint + same-server verification

Pure-logic core of dual-address verify. Three exports:

  * fetchServerFingerprint(baseUrl, user, pass) — one ping (envelope
    'version' extracted alongside type/serverVersion/openSubsonic) plus
    four soft-fail optional calls in parallel (getMusicFolders, getUser,
    getLicense, getIndexes). Optional failures collapse to null fields,
    not whole-fingerprint failure. Subsonic-generic — never branches on
    type === 'navidrome'. indexesDigest is a hash of letter-count plus
    sorted first 20 artist ids, so two probes against the same library
    see the same digest without comparing full payloads.

  * compareFingerprints(a, b) — strict on the ping triple
    (type case-insensitive, serverVersion exact, openSubsonic boolean);
    envelope apiVersion informational only. Body signals counted only
    when both sides have a non-null value; empty musicFolders [] on both
    sides still counts as a matching signal. Result: 'match' (>=1 common
    signal all agreeing) / 'mismatch' (any common differs) /
    'insufficient' (0 common). No 'save anyway' for insufficient in v1.

  * verifySameServerEndpoints(profile, user, pass) — single-address
    short-circuits to ok:true (nothing to verify). Otherwise parallel
    fingerprint probes, then pairwise compare. Ping-fail on any
    endpoint reports the offending host for the UI.

20 unit tests cover the compare matrix (every body signal in every
direction), Navidrome- vs minimal-Subsonic-shape probes, ping-fail,
and all four verify outcomes (ok / unreachable / mismatch /
insufficient). HTTP mocked via vi.stubGlobal('fetch') + plain-object
Response shape (avoiding any Response-polyfill dependency).

* feat(boundary): resolve_host_addresses Tauri command + TS wrapper

Adds one additive invoke for dual-address form hints. Spec §9.1
+ contracts.md §6.

Rust side (src-tauri/src/lib_commands/app_api/network.rs):
  * #[tauri::command] resolve_host_addresses(hostname: String) ->
    Result<Vec<String>, String>
  * tokio::net::lookup_host with a port suffix (':0'); discards the
    port from each SocketAddr, dedupes addresses via HashSet.
  * strip_port helper handles 'host:port', 'ipv4:port',
    '[ipv6]:port', '[ipv6]' (no port), and bare 'ipv6' (left as-is
    for lookup_host to wrap). 7 unit tests cover each shape.
  * Lookup failure → Ok(vec![]) so a DNS hiccup doesn't surface as
    an error toast or block the save flow — form-hint only.

Frontend wrapper (src/api/network.ts):
  * resolveHostAddresses(hostname) — trims, invokes, swallows errors
    to an empty array so consumers get a clean total function.

§04 boundary note: additive command, no breaking change. Added to
the invoke_handler! generate_handler list in lib.rs at the natural
alphabetical-ish slot near migration_run.

* feat(form): AddServerForm — second optional address + share flag + DNS hint

UI side of dual-address. AddServerForm now carries the four new
moving parts spec §6 calls out:

  * Second address field ('Second address (optional)') under the
    primary URL. Placeholder flips to suggest the opposite kind
    of address based on the primary's LAN classification.
  * Contextual hint under the second field when it's empty —
    'add a public address for outside-home use' (primary is LAN)
    or 'add a local address for faster home access' (primary is
    public). Hint disappears once the field has content.
  * Two-LAN client-side check on submit: when both addresses
    classify as LAN, save is blocked with a toast. Reverse case
    (both public) intentionally allowed per spec §6.3.
  * shareUsesLocalUrl checkbox — visibility rule per spec §5.3:
    hidden until the second address has content; shows with the
    persisted value on edit; cleared when the user empties the
    second address before save.

DNS hint: on primary-URL blur we call the Tauri
resolve_host_addresses command and classify the response by
isLanUrl. Literal IPs skip DNS (already classified locally). DNS
miss → no hint surfaces (never blocks save). Used only for the
hint text — connect still goes through pingWithCredentials.

i18n: 9 new keys in en + ru (serverAlternateUrl*, shareUsesLocalUrl*,
serverBothLanError). Other locales fall back to English.

onSave signature widened to 'void | Promise<void>' — ServersTab /
Login both accept that already. The save flow itself still calls
the legacy pingWithCredentials path; verify wiring lands in 2e.

* feat(verify): wire verifySameServerEndpoints into add + dual-edit flows

Save flow now blocks persisting a dual-address profile that fails the
same-server check. Spec §6.4 + §7.4.

handleAddServer:
  * When data.alternateUrl is non-empty, runs verifySameServerEndpoints
    BEFORE the existing ping. mismatch / insufficient / unreachable each
    surface a localized toast and abort the save (no addServer call).
  * Single-address adds keep the legacy single-ping path — no extra
    network round-trip when there's nothing to verify.

handleEditServer:
  * Unconditional save remains the default — but if the edit either
    introduces / changes alternateUrl OR changes url / username / password
    while alternateUrl is set, verify runs first and may block.
  * After persist, invalidates the reachable-endpoint cache for this
    profile id so any sticky cached connect URL from before the edit is
    re-probed on the next access (credentials may have changed, alternate
    may have appeared).

i18n: 4 new toast keys in en + ru (dualAddressVerifying placeholder for
future progress UI, plus mismatch / insufficient / unreachable). Other
locales fall back to English.

announceVerifyResult helper keeps the toast routing in one place so
handleAddServer and handleEditServer share the same surface.

* i18n(settings): dual-address keys across all 9 locales

Adds the 13 new dual-address keys to the remaining 7 locales:
de · fr · es · nl · nb · ro · zh.

  * serverAlternateUrl + placeholderPublic / placeholderLocal
  * serverAlternateUrlHintAddPublic / HintAddLocal (contextual hints
    under the second-address field)
  * serverBothLanError (client-side two-LAN validation)
  * dualAddressVerifying / Mismatch / Insufficient / Unreachable
    (toast strings; Unreachable carries the {{host}} interpolation)
  * shareUsesLocalUrl + Desc (checkbox label + short description)

Placeholders (example.com URL / 192.168.1.100:4533) kept identical
across all locales — same shape the existing serverUrlPlaceholder
already uses.

Single coordinated sweep so every supported language ships dual-
address fully translated rather than falling back to English.

* feat(cover): cover_cache_rename_server_bucket Tauri command

Adds the disk-side companion to the upcoming URL-change remigration
flow (dual-server-address spec §8.3). When a user edits the primary
url so the derived index key changes, the SQLite migration already
re-tags rows via the existing migration_run command — this command
moves the cover-cache bucket on disk so cached WebP tiles stay
reachable under the new key.

Behaviour:
  * old_key == new_key → no-op.
  * Old bucket missing → no-op success (nothing to migrate).
  * New bucket missing → simple fs::rename (fastest path).
  * Both exist → recursive merge with 'prefer existing' on file
    collision (the newer bucket wins; data is never lost).
  * Emits 'cover:bucket-renamed' with {oldKey, newKey} on success
    so the frontend disk-src cache can invalidate stale URLs.

Sanitization: rejects empty, backslash, and '..' path segments at
the FS boundary. Forward slashes are legitimate (a Navidrome
mounted at a subpath like 'music.example.com/navidrome' produces
an index key with one); they're handled by Path::join.

4 unit tests cover key sanitization (accepts real keys, rejects
traversal/backslash) and the merge semantics (unique-file move +
prefer-existing on collision). Registered in lib.rs invoke handler.

* feat(remap): rewriteFrontendStoreKeysForRemap — explicit oldKey→newKey path

Adds the URL-change remigration entry point next to the existing
UUID→indexKey migration. Same plumbing (offline store, hot cache,
analysis-strategy maps) but driven by explicit { oldKey, newKey }[]
mappings instead of being derived from the current servers list.

Also folds in the player-side cleanup the existing path didn't have:
  * queueServerId — if currently bound to a remapped index key,
    repoint to the new one so playback continues through the rename
    instead of looking unbound.
  * analysisStrategyStore — runs the same map-key swap inline (the
    'migrateServerOverrides' helper handles UUID→indexKey, not
    indexKey→indexKey).

Same prefer-existing-on-collision semantics as the disk-side
cover_cache_rename_server_bucket — if a destination key already
carries data, we keep it. 8 unit tests cover no-ops, the four
store rewrites, the queue repoint, the 'leave other servers
untouched' guarantee, and the collision case.

* feat(remap): serverUrlRemigration orchestrator — 4-stage pipeline

Single-file orchestrator that runs the full URL-change remigration when
a profile edit shifts the primary url's derived index key. Spec §8 +
contracts.md §4.

Two exports:
  * indexKeyRemapForUrlChange(prev, next): IndexKeyRemap | null
    — short-circuits scheme-only edits ('http://x' ↔ 'https://x'),
      trailing-slash differences, and alternateUrl-only changes by
      normalizing both sides through serverIndexKeyFromUrl and
      returning null when they match. Empty urls also return null.
  * runIndexKeyRemigration(remap): Promise<IndexKeyRemigrationResult>
    — runs inspect → run → frontend-rewrite → cover-rename in order,
      aborts on the first failure and reports the offending stage.

Failure ordering rationale:
  * inspect / run failures stop the destructive step — DB is
    untouched, the caller can retry safely.
  * frontend rewrite swallows errors (best-effort; zustand persist
    catches up on rehydrate next session).
  * cover-rename failure is reported but does NOT roll back the DB
    rows (that would be even more destructive); covers under the
    old key recover via the existing cover backfill on next access.

10 tests cover the detect logic (5 cases including the path-suffix
case) plus all four pipeline stages with mocked Tauri invoke —
including verifying the legacyId/indexKey mapping shape lands on
both inspect and run calls.

* feat(remap): wire URL-change remigration into ServersTab edit flow

handleEditServer now detects a primary-url index-key change BEFORE
any other save logic (verify, persist, etc.) and orchestrates the
full remigration when one is needed.

Flow:
  * indexKeyRemapForUrlChange(prev, next) — null for scheme-only
    edits / alternateUrl-only edits / no-op edits, so the common case
    falls straight through without prompting the user.
  * On a real remap → confirm modal via useConfirmModalStore.request
    (danger style, plain-language oldKey → newKey copy, explicit
    'cannot be undone'). User cancel → abort save entirely.
  * On confirm → runIndexKeyRemigration pipeline. Failure surfaces a
    stage-specific toast (inspect / run / cover-rename — wording per
    spec §8.4 + the recoverability matrix in serverUrlRemigration.ts).
  * On success → fall through to the existing dual-address verify,
    then auth.updateServer + invalidate cache + ping (unchanged).

i18n: 7 new keys (urlRemigrationTitle / Message with oldKey + newKey
interpolation / Confirm / Progress / FailureInspect / FailureRun /
FailureCoverRename) — full sweep across all 9 locales (en, de, ru,
fr, es, nl, nb, ro, zh).

Test fixup: the offline-store collision test in rewriteFrontendStoreKeys
needed an 'as unknown as' cast — the existing OfflineTrackMeta type
doesn't carry the test-only marker property, and a one-step cast
TS rejected as not overlapping enough.

* feat(magic): magic-string v2 encode/decode with dual-address fields

Adds the v2 wire format for server invites. Spec §10 + contracts.md §5.2.

Encode is opportunistic: payloads with alternateUrl set OR
shareUsesLocalUrl=true emit v2; everything else stays v1 byte-identical.
This means single-address profiles keep producing exactly the same
invite they did before — older receivers can't tell the difference.

v2 shape: { v: 2, url, alt?, shareLocal?, u, w, n? }
  * url — the host's share URL (public by default; LAN if shareLocal),
    NOT necessarily the host's primary URL. Receiver treats it as the
    primary of the new profile (their own index key).
  * alt — the host's alternate address (the other half of the pair).
  * shareLocal — mirrors the host's shareUsesLocalUrl preference so
    onward shares from the receiver behave the same way.

Decode accepts both v1 and v2. v2-only fields are left undefined when
decoding a v1 payload (no '|| undefined' shim — kept absent so zustand
persist diffs stay clean). Defensive: an empty alt on a v2 invite
decodes as if the field were absent, never as ''.

Test updates: 'rejects a payload with the wrong version' now targets
v: 3 (v: 2 became valid). 7 new tests cover the v1/v2 wire-format
choice, both v2 round-trip shapes, the v1-decode-into-v2-fields-
undefined backward-compat case, and the empty-alt edge.

* feat(magic): wire magic-string v2 through invite-encode + paste consumers

Five surfaces now produce / accept v2 invites with the dual-address
fields end-to-end:

Encode side (admin → user invite):
  * MagicStringModal — looks up the saved profile that matches the
    serverUrl prop (primary OR alternateUrl normalize-match) and
    encodes through serverShareBaseUrl + alternateUrl + the share
    flag. Falls back to plain v1 for single-address profiles.
  * UserForm — same lookup + encode plumbing on the in-form
    'Save & get magic string' flow.

Decode side (paste invite into form):
  * AddServerForm useEffect (initialInvite from outer state) +
    handleMagicStringChange (live paste) both pull alternateUrl
    and shareUsesLocalUrl off the decoded payload into form state,
    so the second-address field + checkbox surface immediately on a
    v2 paste.
  * Login form state gains hidden alternateUrl + shareUsesLocalUrl
    fields (not user-editable — Login stays single-address by
    design); v2 paste / initial-invite both populate them so they
    persist with the new profile via addServer. handleQuickConnect
    likewise forwards the existing dual-address shape for
    already-saved profiles.
  * attemptConnect signature widened with the two optional fields;
    addServer / updateServer call sites conditionally include them
    only when alternateUrl is non-empty so single-address profiles
    keep their lean persisted shape.

Both encode helpers share the same magicPayloadAddressFields lookup
(MagicStringModal + UserForm) — the duplication is acceptable for
two co-located small files but a single shared helper would be the
natural place to consolidate if a third encoder appears.

* fix(form): magic-string submit forwards decoded alternateUrl + share flag

AddServerForm.submit's magic-string branch was forwarding only
name/url/username/password from the decoded payload, silently dropping
alternateUrl + shareUsesLocalUrl. A v2 invite pasted into the
magic-string field and saved would land in the store as a single-
address profile even though handleMagicStringChange had already
populated the dual-address fields into form state for display.

Now the magic branch picks the dual-address fields off the decoded
payload (same conditional spread as the non-magic branch a few lines
down) so v2 invites round-trip end-to-end through the form.

* fix(verify): extractUserId drops username fallback to avoid false mismatches

Spec §7.2 footnote: 'fallback (normalized username) only if no id on
either side'. The old extract unconditionally fell back to the
authenticated username whenever user.id was empty — but the
comparator can't tell username-fallback apart from a server-supplied
id. So a server pair where endpoint A returns user.id='42' and
endpoint B only returns user.username='frank' would land in compare
with userId values '42' vs 'frank' and report mismatch on what is
actually the same user on the same server.

Now extractUserId returns null when user.id is absent. Both sides
returning null means compareFingerprints skips userId as a common
signal (correct behaviour per the §7.3 'both sides have a value'
rule). One new test pins it; the call site drops the redundant
fallbackUsername argument.

* fix(remap): rewriteFrontendStoreKeysForRemap migrates coverStrategyStore

Spec §8.2 lists 'analysis/cover strategy maps' as targets of the
URL-change remigration. The For-Remap path covered analysis but
missed cover — a user-set cover strategy override (e.g. 'aggressive'
for one server) would silently drop when the user edited that
profile's primary URL, because the key tagged under the old index
key never made it to the new one.

Same shape as the analysis remap inline: prefer-existing on
collision (newer key wins), delete the legacy entry afterwards.
One new test pins the move; setup adds a fresh useCoverStrategyStore
reset between cases.

* fix(cover): is_safe_index_key rejects absolute paths + drive letters

Defense-in-depth gap in cover_cache_rename_server_bucket. The old
sanitizer only rejected backslashes and '..' segments — '/etc/passwd'
on Unix and 'C:\Windows' on Windows both passed. Path::join with an
absolute argument REPLACES the base path, so root.join('/etc/passwd')
on Unix would walk out of cover-cache entirely.

Real index keys never reach this state — they come out of
serverIndexKeyFromUrl which strips schemes and trailing slashes, so
no leading separator and no drive-letter prefix is ever produced.
But the comment promises 'defense in depth' and that defense is
worth completing.

Now rejects:
  * empty keys (would join to the cover-cache root itself)
  * leading '/' or '\'
  * Windows drive-letter prefix 'X:' (case-insensitive ASCII letter)
  * backslashes anywhere (separators are forward-slash only)
  * '..' segments after split('/')

One new Rust test covers all four cases.

* fix(connection): isLan badge reflects active endpoint, not primary url

useConnectionStatus.isLan was reading isLanUrl(server.url) — the
*primary* address — so a dual-address profile that had fallen over to
its public alternate kept advertising 'LAN' in the badge until the
user looked at the server URL itself. Spec call-site-checklist line
25: 'active endpoint kind for badge (LAN vs extern)'.

Now: ensureConnectUrlResolved returns probe.endpoint.kind on success;
the hook tracks the latest kind in local state and surfaces that.
Pre-first-probe fall-through keeps the old primary-URL classification
so the badge has something to render at mount time.

Three tests pin the three states (LAN-active after probe, public-
active after fallback, primary-fallback before first probe completes);
plus one for the online-event handler that invalidates the cache and
re-probes.

* fix(server): dedupe concurrent pickReachableBaseUrl calls for same profile

Multiple call sites probe on roughly the same beat — useConnectionStatus
120-s tick + online handler + initial mount, switchActiveServer,
bindIndexedServer, and ServersTab.testConnection. Two near-simultaneous
probes for the same profile both observed an empty cache, both pinged
every endpoint, and raced to write the sticky URL with last-write-wins.
On a dual-address profile the slower probe could stomp the correct
LAN sticky a millisecond after it was set.

Now: an in-flight Map<profileId, Promise<PickReachableResult>>; a
second call for the same id during an active probe returns the same
promise instead of starting a fresh one. The finally-clear keeps the
dedup window narrow (one settled probe → next call probes fresh).
invalidateReachableEndpointCache deliberately doesn't touch the
in-flight map — the racing probe's own finally will clean up.

Three tests pin it: two concurrent calls share one ping; a fresh
call after the previous settled does ping again; plus the existing
shareBaseUrl two-LAN-with-flag-on test + the two-public-default test
for completeness.

* refactor(magic): extract magicPayloadAddressFields to single shared helper

The lookup that turns a serverUrl into the v2-encode-ready
{ url, alternateUrl?, shareUsesLocalUrl? } shape was duplicated
byte-identically between MagicStringModal.tsx and UserForm.tsx —
both Navidrome admin user-mgmt encode sites. Workdocs §03 / §1a
'one source of truth for behavior'.

Now lives in src/utils/server/serverMagicString.ts as a named
export. Both call sites import + pass the current servers list
(via useAuthStore.getState().servers) — keeps the helper pure so
it's straight to unit-test if a third encoder ever appears.

* fix(cover): wire cover:bucket-renamed listener for URL-change remigration

cover_cache_rename_server_bucket emits cover:bucket-renamed on
successful rename / merge, but no frontend listener was wiring it in.
After a URL-change remigration the in-memory disk-src cache still
held entries pointing at `{root}/{oldKey}/…/.webp` paths the disk
no longer carries — the next read would serve a stale URL until
the entry naturally aged out.

New: forgetDiskSrcForServer(serverIndexKey) in diskSrcCache drops
every cover entry under one server key in one pass (the existing
forgetDiskSrcPrefix needs a non-empty coverArtId and can't blanket-
clear a server). useCoverArtBridge subscribes to cover:bucket-
renamed and calls it with oldKey.

Tests: forgetDiskSrcForServer happy path, empty-key defensive
no-op, no-match no-op; plus a regression-pin on the existing
forgetDiskSrcPrefix so the two helpers don't drift in semantics.

* test(dual-server): fill the high-impact coverage gaps from the branch review

Adds the tests the review identified as missing on the hot-path UI
flows + the partial-fail / alt-only edges:

  * AddServerForm.test.tsx (new) — five component tests:
    single-address save / dual-address save / two-LAN block-with-
    toast / v2 magic-string paste forwarding alt + share flag /
    edit-flow stripping alt+flag when the field is emptied.
  * Login.test.tsx (new) — v2 invite paste persists alternateUrl +
    shareUsesLocalUrl onto the saved profile; v1 invite leaves
    those fields undefined.
  * shareLink.test.ts — alternateUrl-only match for
    findServerIdForShareUrl (the dual-address paste case where the
    host shared the LAN URL via shareUsesLocalUrl=true); 'first hit
    wins' across two profiles where both match.
  * serverFingerprint.test.ts — partial-fail mix (folders+user ok,
    license+indexes rejected) so a Promise.allSettled regression
    wouldn't go silent.
  * cover_cache/mod.rs — rename_bucket_inner extracted as a
    testable FS-only helper (the Tauri command wrapper now just
    locks state + calls it + emits the event), plus six tests
    covering empty/unsafe keys, no-op-when-missing, no-op-when-
    equal, simple-rename, merge-with-prefer-existing.

Also: every test fixture that I authored on this branch using
'frank' / 'frank@example.com' as a stand-in username/email
swapped to 'tester' / 'tester@example.com' — keeping personal
names out of test data is the codebase convention (see
factories.ts) and is now a memory rule.

* fix(test): typed mock access for pingWithCredentials in useConnectionStatus

vi.mocked(...) returns the mock typed properly — bare .mock fails
tsc because the imported function signature isn't a vi.Mock at
import time.

* docs(changelog): dual server address (PR #880)

* fix(test): align diskSrcCache tests with main cover storage key API

After rebase onto main, forgetDiskSrcPrefix takes a CoverArtRef-shaped
argument and storage keys include cacheKind; merge coverDiskUrl tests
from main with dual-address forgetDiskSrcForServer coverage.

cucadmuh bc85065316 fix(analysis): persist failed tracks and reconcile progress counts (#867)
* fix(analysis): persist failed-track suppression and reduce aggressive polling

Persist unsupported/broken analysis tracks as failed entries and expose them in Settings with track metadata, export, and targeted rescan actions. Also make aggressive-mode completion checks cheap by gating re-entry on live track-count changes with a startup seed and 5-minute recheck cadence.

* fix(analysis): mark unsupported decode tracks as failed in cpu-seed

When full-seed falls back to waveform-only (no EBU loudness) or enrichment decode fails, persist analysis_track status as failed so aggressive backfill does not requeue the same unsupported tracks indefinitely.

* fix(analysis): reconcile legacy ready tracks without loudness

Auto-mark legacy ready tracks that only miss loudness as failed during needs-work checks so analysis progress converges instead of staying permanently pending.

* docs(changelog): add failed-analysis recovery notes for PR 867

Document persistent failed-track handling, analytics strategy controls, and low-cost aggressive-mode recheck behavior in the 1.47.0 changelog.

* fix(i18n): align settings locale coverage across all languages

Sync missing Settings keys for all shipped locales and replace recent English fallbacks with localized strings so analytics and backup UI text stays consistent outside en/ru.

cucadmuh e8e41752a7 feat(playback): global speed with three strategies (#852)
* feat(playback): global speed with three strategies

Add Settings → Audio and player-bar controls for global playback speed
(speed with auto pitch correction as default, varispeed, manual pitch shift).
Time-stretch runs on a background worker; Orbit sessions force 1.0× passthrough.

* fix(playback): align seekbar, seek, and progress on content timeline

Unify UI timebase across varispeed and preserve strategies: full-track
duration, speed-scaled progress for DSP paths, and content-timeline seeks
without varispeed scaling. Reset the sample counter after seek so clicks
land correctly; restart playback on strategy/enable changes instead of
fragile hot-switching.

* fix(ui): anchor playback speed popover like volume controls

Replace the centered EQ-style modal with a player-bar popover (outside
click, Escape, reposition on scroll). Show compact controls in the bar
and overflow menu; keep strategy hints and labels in Settings only.

* docs(release): CHANGELOG and credits for playback speed (PR #852)

* docs(changelog): add playback speed entry for PR #852

* fix(clippy): simplify raw_counter_samples branch for CI

Collapse duplicate if branches flagged by clippy::if-same-then-else.

* fix(ui): wheel on pitch slider adjusts pitch in speed popover

In compact player-bar controls, scroll over the pitch row changes pitch;
elsewhere in the panel changes speed. Stop propagation so overflow menu
wheel does not tweak volume.

* fix(playback): address PR #852 review and drop ineffective dynamic imports

Translate playback-rate strings for de/fr/es/zh/nb/nl/ro; restamp sample
counter on live preserve-path speed changes; use neutral rate atomics for
radio progress; static-import playerStore in playListenSession (move preview
volume sync to previewPlayerVolumeSync side-effect module).

* fix(i18n): translate playback-rate strategy labels in all locales

Replace leftover English Varispeed/Pitch strings in ru and other non-en
settings blocks so popover strategy buttons and hints read natively.

* fix(i18n): refine German varispeed label to "Tonhöhe folgt dem Tempo"

cucadmuh 5bf2441ccf feat(library): local library index and search (preview) (#846)
* feat(library): scaffold psysonic-library crate with v1 schema and store (#791)

Adds a new workspace crate that will host the unified track store and the
upcoming sync engine. PR-1a covers spec phases A1–A6:

- migrations/001_initial.sql: full v1 schema — sync_state, track, album,
  artist, track_fts (+ ai/ad/au triggers), track_extension, track_offline,
  track_id_history, track_fact, track_artifact, canonical_track,
  canonical_identity, track_canonical_link, canonical_enrichment_link, and
  all §5.2 partial indexes.
- store::LibraryStore: WAL + foreign_keys=ON SQLite connection rooted at
  app_data_dir/library.sqlite (distinct from the analysis cache, which
  uses app_config_dir). schema_migrations table + idempotent embedded
  migration runner; LIBRARY_DB_SCHEMA_VERSION = 1.
- repos::TrackRepository::upsert_batch: 35-column transactional upsert
  with ON CONFLICT(server_id, id) all-fields rewrite; FTS rows follow via
  the triggers.
- search::search_tracks: minimal bm25-ordered FTS5 helper scoped to a
  single server_id, filtering deleted rows.
- filter::FilterFieldRegistry: static v1 registry (text, genre, year,
  starred = V1; bpm = SchemaV1UiLater; user_rating/suffix/bit_rate =
  Planned). Entity routing is a silent skip per §5.13.3.

No Tauri commands, no frontend, no sync — those land in PR-2..PR-7.

PR-1b will follow with the migration-runner edge-case tests, the
initial_sync_cursor_json read/write API, and the breaking-migration hook
stub (P22).

* feat(library): A7 migration-runner safety net + initial-sync cursor API (PR-1b) (#792)

* feat(library): wire migration-runner safety net and initial-sync cursor API

PR-1b — Phase A7 infrastructure on top of PR-1a. Production behaviour
is unchanged at v1 launch; everything here is plumbing that PR-3 will
consume.

- store::run_migrations_with: testable entry point that takes an explicit
  migration slice, a min-compatible-version threshold, and a breaking-bump
  hook. The prod `run_migrations` fixes those to MIGRATIONS,
  LIBRARY_DB_MIN_COMPATIBLE_VERSION, and the no-op stub. The slice is now
  sorted defensively before applying.
- store::LIBRARY_DB_MIN_COMPATIBLE_VERSION: new public constant (currently
  equal to LIBRARY_DB_SCHEMA_VERSION). When a future release needs to
  invalidate v1 data, bumping this above the max applied version trips
  the hook on next open per spec §5.7 / P22.
- store::MigrationOutcome (Applied | BreakingBump): crate-internal signal
  callers can branch on. PR-1b consumers ignore it; PR-3 / Settings will
  surface the "library rebuilt after update" toast when it surfaces.
- store::handle_breaking_schema_bump: documented no-op stub. The drop +
  resync logic lands with the first real breaking bump.
- repos::SyncStateRepository: ensure(server_id, scope) idempotently
  inserts a default row; get_initial_sync_cursor / set_initial_sync_cursor
  read and write sync_state.initial_sync_cursor_json via
  serde_json::Value. The set uses ON CONFLICT … DO UPDATE scoped to the
  cursor column only, so phase / poll-stats / tier survive cursor writes
  intact.
- Tests cover: additive 002-style migration preserves prior data
  (spec §5.7 explicit integration test), runner sorts an unsorted source
  slice, breaking-bump hook fires when max applied < min_compatible,
  hook does not fire on a fresh DB, cursor round-trips a nested
  serde_json::Value, ON CONFLICT preserves sibling columns, library_scope
  separates rows per server.

End-to-end "kill mid-500k-sync → resume same cursor" stays out of scope
per the kickoff answer — it belongs to PR-3 / C2 where the
InitialSyncRunner lives.

* test(library): cover AC A3 — 500-row upsert_batch under perf budget

* feat(library): Subsonic REST client for the sync engine (Phase B, PR-2) (#793)

Phase B (B1-B9 per spec §10) — pure-Rust Subsonic client that the
library-sync engine (PR-3) will drive. No Tauri commands, no events;
the surface is added internally to psysonic-integration as a sibling
of the existing navidrome native-REST module.

- B1 — SubsonicClient + ping over /rest/{method}.view. Auth via the
  legacy salted-md5 token (spec v1.13+, advertised as 1.16.1). New
  SubsonicCredentials helper computes token = md5(password || salt)
  and ships a per-process unique salt nonce so back-to-back calls
  don't repeat.
- B2 — get_scan_status → ScanStatus { scanning, count, folder_count,
  last_scan }. Lightweight poll for the Huge-tier path (§6.2.2).
- B3 — get_album_list2(type, size, offset, musicFolderId?) +
  get_album(id). The two-call pattern the sync engine walks during
  initial ingest (§6.3).
- B4 — search3(query, songCount, songOffset, musicFolderId?). Empty
  query → all songs paged (Navidrome quirk, spec §2.4).
- B5 — get_indexes(musicFolderId?, ifModifiedSince?). Conditional
  fetch for file-tree fallback (S3 / §3.1).
- B6 — get_song(id). Error code 70 maps to the dedicated
  SubsonicError::NotFound variant so the tombstone reconciler can
  match on the variant instead of parsing strings.
- B8 — get_artists(musicFolderId?). ID3-path artist index; clients
  compare ArtistIndex.last_modified_ms against the local watermark
  to decide if a delta pass is needed (§2.2.1).
- B9 — fingerprint_sample helper picks every-Nth track id for the
  server-fingerprint verify pass. Sampling is deterministic so
  reruns probe the same tracks. The verify-and-compare glue itself
  is library-side (PR-3 territory, deps on the store).

Tests cover envelope parsing (status=ok/failed, code 70 → NotFound,
missing body key), credentials (md5 vectors, salt uniqueness across
1k rapid calls, salt differs per from_password call), each endpoint
end-to-end through wiremock with query-param matchers, OpenSubsonic
forward-compat (unknown fields ignored on Song), and the trailing-slash
base-URL normalisation.

Cargo.toml — adds query + form + multipart to psysonic-integration's
reqwest feature set. PR-2's client needs `query`; the other two were
already used by existing navidrome::covers / remote::lastfm code and
only worked via top-crate feature unification. Aligning the crate's
own deps means `cargo test -p psysonic-integration` now compiles
without depending on the workspace build.

Out of scope: capability detection (C1 / PR-3), Navidrome native
bulk path (uses existing psysonic-integration::navidrome::queries),
fixtures harness expansion (G1).

* feat(library): subsonic client follow-ups from PR-2 review (PR-2b) (#794)

Picks up the three non-blocking items from cucadmuh's PR-793 review
(handoffs/2026-05-19-pr-793-review.md) before PR-3 starts on top.

- Fresh `(token, salt)` per request. `SubsonicClient` now caches the
  plaintext username + password and derives a new `SubsonicCredentials`
  inside `send()` for every endpoint call — matches the frontend's
  `subsonicClient.ts` `getAuthParams()` lifecycle and follows Subsonic
  replay-resistance guidance. Test path keeps a `with_static_credentials`
  constructor so wiremock matchers stay deterministic. New
  `build_credentials` (`pub(crate)`) routes the two modes.
- `SUBSONIC_CLIENT_ID` now carries the crate version
  (`psysonic/<CARGO_PKG_VERSION>`) — aligns with the frontend's
  `psysonic/${version}` so Navidrome log lines correlate across the
  WebView and Rust sync paths.
- `Song.mbid_recording` gains the `musicBrainzId` serde alias (plus the
  schema-column spelling) so the OpenSubsonic field lands on the same
  hot column the §5.1 schema names. P13 strong-key matching can now key
  off it on ingest.
- `get_song_with_raw` / `get_album_with_raw` return both the typed
  projection and the raw `serde_json::Value` body sub-tree. PR-3 ingest
  will write that raw value verbatim into `track.raw_json`, so
  OpenSubsonic extensions (`contributors`, `replayGain`, future fields)
  survive without manual field mirroring. Internal `parse_envelope_body`
  extracts the validation + body-key lookup once; `parse_envelope` and
  the new `parse_envelope_with_raw` share it.

Tests cover: `from_password` produces unique salt/token across two
back-to-back calls (direct + over-the-wire via wiremock
`received_requests`), static mode returns the same triple,
`c` query param starts with `psysonic/` and equals `SUBSONIC_CLIENT_ID`,
`get_song_with_raw` preserves untyped fields (`replayGain`,
`contributors`) in the raw value, `get_album_with_raw` keeps per-track
extensions in `raw.song[i]`, error 70 still maps to `NotFound` on the
raw variant, and `Song` deserializes `musicBrainzId` and
`mbid_recording` interchangeably.

B9 fingerprint-verify glue and the wider raw-ingest call sites stay
with PR-3 / C2 as the review's §5 / §7 checklist directs.

* feat(library): capability probe + sync_state accessors (Phase C1+C7, PR-3a) (#795)

First sub-PR of Phase C (sync orchestrator). Lands the foundation that
PR-3b's InitialSyncRunner consumes — pure plumbing, no runners or
background tasks yet.

- C1 capability probe. `psysonic_library::sync::CapabilityProbe::run`
  drives the §6.1 probe chain: Subsonic ping (captures `ServerInfo`
  envelope metadata for server-type / OpenSubsonic detection), then
  best-effort probes for search3 / getScanStatus / getIndexes, plus an
  optional Navidrome native bulk probe (caller passes
  `NavidromeProbeCredentials`). `CapabilityFlags(u32)` matches the
  §6.1.1 bitfield: NavidromeNativeBulk / SubsonicSearch3Bulk /
  ScanStatusAvailable / OpenSubsonic / UnstableTrackIds / FileTreeBrowse.
- C7 sync_state accessors. `SyncStateRepository` gains get/set
  capability_flags, get/set sync_phase (idle / probing / initial_sync
  / ready / error), and column-scoped setters for server_last_scan_iso,
  indexes_last_modified_ms, artists_last_modified_ms, library_tier.
  Every setter uses `ON CONFLICT … DO UPDATE` scoped to its own column
  so concurrent watermark writes don't clobber each other.
- Supporting additions in `psysonic-integration`:
  - `subsonic::SubsonicClient::server_info()` extracts `ServerInfo`
    from the ping envelope (server_type, server_version, api_version,
    open_subsonic). Re-uses `send()` so auth lifecycle is the same.
  - `navidrome::probe::native_bulk_available(url, token)` does the
    `GET /api/song?_start=0&_end=1` Bearer-auth probe. Returns
    Ok(true) on 2xx, Ok(false) on 4xx (auth ok but endpoint missing),
    Err on 5xx. Probe-only — full nd_list_songs port is PR-3b.
- `psysonic-library/Cargo.toml` gains a `psysonic-integration`
  dependency (sync calls into Subsonic + Navidrome probes). DAG stays
  acyclic: integration does not depend on library.

Per cucadmuh's PR-3 kickoff answer (handoff `2026-05-19-pr3-kickoff.md`):
- Crate placement: option A — sync lives in `psysonic-library/src/sync/`,
  no new psysonic-sync crate.
- N1 gate: probe is `/api/song?_start=0&_end=1` only; `nd_list_artists_by_role`
  is NOT required (Q3 answer + N1 ingest port lands in PR-3b).
- UnstableTrackIds: set for Navidrome via `ServerInfo.server_type`,
  cleared for generic Subsonic.

Tests added: 23 across library/sync, library/repos/sync_state,
integration/subsonic, integration/navidrome/probe. Cover bitfield
contains/insert/remove + spec bit values, probe across mixed-capability
servers (full Navidrome, minimal Subsonic, broken endpoints), ping-failure
short-circuit, optional Navidrome creds gating N1, sync_state column-scoped
upserts (capability_flags / sync_phase / watermarks / library_tier),
cross-column independence (capability writes don't reset cursor),
ServerInfo extraction from ping envelope, Navidrome bulk probe across
2xx/4xx/5xx.

* feat(library): InitialSyncRunner + C12 backoff + C13 id remap (Phase C2/C12/C13, PR-3b) (#796)

Second sub-PR of Phase C — wires the actual ingest path on top of
PR-3a's capability + sync_state foundation. Runner is pure async Rust:
PR-3d will spawn it inside a tokio task and emit Tauri progress events
on top.

- C2 InitialSyncRunner. Drives spec §6.3 IS-1 → IS-6: probe-derived
  IngestStrategy (enum N1/S1/S2/S3, selector picks N1 → S1 → S2 chain
  per kickoff Q3), per-page upsert loop, cursor flush after every
  successful batch, IS-4 best-effort getArtists watermark, IS-5
  getScanStatus.lastScan capture, IS-6 phase=ready + cursor cleared.
  Resume is automatic: a non-empty initial_sync_cursor_json restarts
  at the persisted offset; a strategy mismatch between cursor and
  capability flags surfaces as SyncError::CursorIncompatible.
- C12 backoff. sync::backoff::Backoff implements the §6.8 schedule
  (2s → 4s → … cap 120s) with ±25% jitter via deterministic salt.
  retry_with_backoff wraps every endpoint call: transport / Navidrome
  failures retry up to MAX_ATTEMPTS_PER_BATCH (5), the cursor never
  advances on failure, success resets the counter. Cancellation
  AtomicBool is checked between attempts.
- C13 id remap. TrackRepository::upsert_batch_with_remap performs the
  §6.9 detect-and-rebind pass inside the same SQLite transaction as
  the upsert: a content_hash or server_path collision on a different
  existing id triggers UPDATE of child tables (track_offline,
  track_extension, track_fact, track_artifact, track_canonical_link),
  INSERT INTO track_id_history, DELETE old track row. Off when
  UnstableTrackIds is clear (generic Subsonic). New
  TrackIdHistoryRepository read-side helper for forward lookups
  (analysis cache reuse, Phase E).
- IngestStrategy enum + selector (sync::strategy) — N1 → S1 → S2;
  N1 requires Navidrome bearer credentials at runtime (skipped when
  None). S3 is enumerated for future file-tree fallback but returns
  StrategyUnsupported in v1 per kickoff Q3.
- InitialSyncCursor (sync::cursor) — JSON-serialisable
  { strategy, phase, library_scope, ingested_count, strategy_state }.
  StrategyState tagged enum: LinearOffset { offset } for N1/S1,
  AlbumCrawl { album_offset, current_album_id } for S2.
- mapping::subsonic_song_to_track_row + navidrome_song_to_track_row
  centralise the JSON → TrackRow projection. Subsonic path also reads
  replayGain.{trackGain,albumGain} from the raw value so PR-3b doesn't
  drop the columns that PR-2b reserves on TrackRow.
- Supporting bits in psysonic-integration:
  - subsonic types now derive Serialize so the runner can round-trip
    a typed Song back into raw JSON when feeding upsert.
  - navidrome::queries gains nd_list_songs_internal — pure async
    function (no #[tauri::command] decorator) that the N1 ingest
    loop calls directly. The existing Tauri command wraps it.

Tests added across sync::* and repos::track_id_history. Wiremock
covers S1 happy-path, mid-cursor resume from a persisted offset,
strategy mismatch → CursorIncompatible, 503 transient → retry-then-
succeed, AtomicBool cancellation → Cancelled, N1 paginated /api/song
ingest, S2 album crawl, and §6.9 remap firing under UnstableTrackIds
during an actual sync. Backoff schedule + jitter formula pinned.
TrackRepository remap path covered by content_hash collision,
server_path collision, hash+path-missing skip, identity-noop, and
remap-off compatibility with the existing upsert_batch contract.

Also fixes cucadmuh's PR-3a review minor 1: drops the dead
`mount_ok` scaffolding from sync::capability tests.

Out of scope per kickoff Q2:
- DeltaSyncRunner + tombstones → PR-3c
- Background task lifecycle, cancellation wiring, progress emit
  throttle, adaptive scheduler, request budget, bandwidth lane → PR-3d
- Tauri command surface for "sync now" / progress events → PR-5

* feat(library): search3 raw envelope fidelity for S1 ingest (PR-3b follow-up) (#797)

Picks up cucadmuh's PR-3b review minor 1: the S1 path in
InitialSyncRunner was reserialising the typed `Song` for
`track.raw_json`, dropping unknown OpenSubsonic extensions
(`replayGain`, `contributors`, …). N1 and S2 already carry the raw
sub-tree verbatim through `nd_list_songs_internal` and
`get_album_with_raw`; S1 now matches via the new
`SubsonicClient::search3_with_raw` mirror of the PR-2b pattern.

- subsonic::SubsonicClient::search3_with_raw — returns
  `(SearchResult, serde_json::Value)`; uses the existing
  `parse_envelope_with_raw` so error 70 / `Api { code, .. }` mapping
  stays consistent.
- sync::initial::run_s1 now calls `search3_with_raw` and feeds the
  per-song raw sub-tree (`raw_body.song[i]`) into
  `subsonic_song_to_track_row` instead of a typed reserialise.

Tests cover `search3_with_raw` round-trip on a payload with
`replayGain` + `contributors` (verifies the raw value preserves both)
and the empty-result case where the body is `searchResult3: {}`.
Plus an end-to-end S1 ingest test that asserts the persisted
`track.raw_json` column contains the OpenSubsonic extensions after a
full runner pass, and that `replay_gain_track_db` / `_album_db` still
land on the typed columns via the mapping helper.

* feat(library): DeltaSyncRunner + TombstoneReconciler (Phase C3/C4, PR-3c) (#798)

Third sub-PR of Phase C — drives targeted delta passes on top of
PR-3a/b's foundation. Pure async; PR-3d will spawn it inside the
background scheduler.

- C3 DeltaSyncRunner. Walks spec §6.4 DS-0 … DS-9:
  - DS-0/1/2/3 cheap probe via `getArtists` (small/medium tier) or
    `getScanStatus` (huge tier when `ScanStatusAvailable`). Server
    watermark match → up_to_date short-circuit, scan-in-progress →
    deferred_scanning report; zero further requests in either case.
  - DS-4 targeted ingest. Strategy from capability_flags: N1-delta
    when NavidromeNativeBulk is set, otherwise S2-delta. S1 has no
    delta semantic so it's not used here.
    - N1-delta: GET /api/song _sort=updated_at _order=DESC, pages
      until rows fall under the local `MAX(server_updated_at)`
      watermark; out-of-band rows in the same page are dropped.
    - S2-delta: getAlbumList2 type=newest then type=recent, up to
      a small page cap; getAlbum is fetched only for album_ids the
      local store doesn't already have. Known albums are skipped
      so a play-bump under "recent" doesn't re-ingest the whole
      tracklist.
  - DS-6 id remap reuses TrackRepository::upsert_batch_with_remap.
  - DS-9 stamps next watermark (artists_last_modified_ms or
    server_last_scan_iso) + last_delta_sync_at.
  - DS-5 canonical matcher (Phase H) and DS-7 starred delta are out
    of scope for PR-3c.
- C4 TombstoneReconciler. Caller-driven streaming: each
  `reconcile_chunk(budget)` picks the next `budget` ids ordered by
  synced_at ASC, calls getSong, marks deleted=1 on code 70, and
  refreshes synced_at on every checked id so the queue rotates.
  Mode A (manual integrity) loops until checked == 0; Mode B
  (auto-threshold) tests `should_auto_reconcile(local, server, pct)`
  per delta tick and runs a small budgeted chunk. Memory bounded —
  no full local-id list ever held in RAM.

- SyncStateRepository: new getters for artists_last_modified_ms,
  server_last_scan_iso, library_tier; new
  set_last_delta_sync_at stamp helper. All column-scoped upserts
  preserve neighbouring fields.

Tests cover DS-2 short-circuit (watermark match), DS-3 defer
(scanning=true), N1-delta watermark cutoff (3 fresh + 2 stale rows →
only 3 upserted), S2-delta known-album skip (mock 404 on al_known
guards the assertion), DS-9 watermark + last_delta stamping,
should_auto_reconcile threshold cases (gap, tolerance, server=0,
local<=server), reconcile_chunk code-70 → deleted=1, budget +
ordering (oldest first, newest untouched), empty-store noop, and
cancellation.

PR-3d (background task, probe→flags wiring, progress emit, adaptive
scheduler, request budget, bandwidth throttle) lands next on the
same integration branch.

* feat(library): sync supervisor + progress channel + DS-8 wiring (Phase C5/C6, PR-3d1) (#799)

First half of PR-3d (cucadmuh-approved split per kickoff Q2).
Pure-Rust lifecycle + progress infrastructure on top of the runners
from PR-3a/b/c. Tauri events stay in the top crate (PR-5); this PR
only ships the channel the top crate will subscribe to.

- C5 SyncSupervisor. Spawns a sync workload inside a tokio task,
  owns the cancellation AtomicBool, and exposes a single-consumer
  mpsc receiver for ProgressEvent. join() returns the inner
  Result<(), SyncError>; panics surface as Storage so callers
  never need to know about tokio internals.
- C6 progress channel. New sync::progress module:
  - ProgressEvent enum — lean variants
    (PhaseChanged / IngestPage / Remapped / Tombstoned /
    Completed / Error). Server / scope context lives on the
    channel side (one supervisor = one scope).
  - Progress trait + NoopProgress default + ChannelProgress
    forwarding through tokio mpsc. Throttle is the simple
    last-emit-timestamp gate; terminal events (Completed /
    Error) bypass it.
- InitialSyncRunner + DeltaSyncRunner gain with_progress(...)
  builders. IS-1 / IS-6 emit PhaseChanged + Completed; delta
  emits PhaseChanged at strategy pick, Tombstoned at DS-8, and
  Completed at DS-9. Defaults to NoopProgress so existing call
  sites keep working.
- DS-8 wired. DeltaSyncRunner::with_tombstone_budget(n) drives
  TombstoneReconciler::reconcile_chunk(n) after DS-4 ingest;
  shares the runner's cancellation flag + sleep override. The
  DeltaSyncReport gains tombstones_checked / tombstones_deleted
  so callers can act on the counts.
- capability::probe_and_persist helper. Chains
  CapabilityProbe::run with sync_state writes: sets phase to
  "probing" before the probe, persists capability_flags, then
  drops back to "idle". PR-3d2 (the scheduler) will call this in
  front of every initial / delta run so the stored flags reflect
  the live server.

Tests cover: ChannelProgress throttle (zero-interval pass-through,
terminal bypass, non-terminal collapse, sender alive after
receiver drop), SyncSupervisor task completion + cancel +
panic-as-Storage + receiver-take-once, probe_and_persist
round-trip through SyncStateRepository (flags persisted, phase ends
at "idle"), DS-8 reconcile-after-ingest landing tombstones on
code 70 returns.

PR-3d2 follows with the adaptive scheduler (C8), request budget
(C9), poll EWMA (C10), and the bandwidth / queue priority lane
(C11).

* feat(library): adaptive scheduler + request budget + EWMA poll + bandwidth (Phase C8/C9/C10/C11, PR-3d2) (#800)

Second half of PR-3d per cucadmuh's kickoff-Q2 split. Wraps the
runners + supervisor from PR-3a/b/c/d1 into a tick-driven background
scheduler. Top crate (PR-5) plumbs the timer.

- C8 BackgroundScheduler. Tick-based — caller drives the interval,
  scheduler decides whether the tick should run. is_due(now_ms)
  checks sync_state.next_poll_at; tick(now_ms) either skips
  (not due / PrefetchActive pause), or runs a DeltaSyncRunner with
  the right budget + tombstone trigger, then stamps the next
  poll_at via the adaptive formula. No tokio task ownership —
  tests stay deterministic, PR-5 plugs spawn behaviour to taste.
- C9 RequestBudget. PassKind enum (PollTick / DeltaLight /
  DeltaMismatch / InitialSync) with caps per spec §6.2.5
  (1 / 50 / 200 / unlimited). RequestBudget::has_room(used) gates
  the runner; PR-3d2 ships the data type, runner enforcement of
  the cap is a future tightening (DeltaSyncRunner already has its
  own page cap so the soft cap mostly informs Settings).
- C10 PollStats EWMA. New sync::poll_stats with PollStats
  (artist_count, ewma_bytes, ewma_duration_ms, library_tier),
  observe()/set_artist_count()/reclassify() helpers, the §6.2.2
  tier table (<2k / 2k-15k / >15k or ewma_bytes >2MB), and
  next_interval_ms following the spec formula
  (base * load_factor * artist_factor, load_factor clamped
  [1, 10]).
- C11 PlaybackHint + ParallelismBudget. PlaybackHint enum
  (Idle / Playing / PrefetchActive) resolved to a
  ParallelismBudget { max_concurrent, min_request_gap_ms }.
  PrefetchActive pauses bulk (`max_concurrent = 0`) per
  §6.2.4; the scheduler honours it via tick short-circuit.
- Auto-tombstone wire. Before running the DeltaSyncRunner the
  scheduler tests `should_auto_reconcile(local, server, pct)`
  against the persisted counts; on threshold trip it sets
  `with_tombstone_budget(200)` (the §6.2.5 DeltaMismatch cap).
- SyncStateRepository gains poll_stats_json get/set,
  next_poll_at get/set, local_track_count get/set, and
  server_track_count get/set — all column-scoped upserts.

Tests: ~30 new across poll_stats / budget / bandwidth / scheduler.
EWMA seed + smoothing, tier-classification edges (artist + size
overrides), next-interval formula bounds (idle base, slow-network
load_factor clamp), RequestBudget caps per pass, ParallelismBudget
resolution, scheduler is_due (no schedule / future schedule),
tick short-circuit (not due, PrefetchActive pause), tick runs
delta and persists next_poll_at, auto-tombstone trigger above
5 % threshold, PollStats round-trip through SQLite.

Together with PR-3d1 this finishes Phase C — Tauri command surface
(D1-D4) lands with PR-5.

* feat(library): read-only Tauri command surface (Phase D1 part 1, PR-5a) (#801)

First sub-PR of Phase D per cucadmuh's kickoff Q1 split. Lands the
LibraryRuntime Tauri State plus the 8 read-only library commands
from spec §7.1. No SyncSupervisor spawn, no sync lifecycle commands,
no credentials store — those land in PR-5b.

- New psysonic_library::runtime::LibraryRuntime — Tauri State
  wrapping Arc<LibraryStore>. Top crate's lib.rs setup() now calls
  LibraryStore::init(app), wraps the result in the runtime, and
  app.manage's it. Mirrors the AnalysisCache wiring above it.
- New psysonic_library::dto module — camelCase wire DTOs per
  src-tauri/CLAUDE.md: SyncStateDto, LibraryTrackDto (flat
  projection over the track hot columns + raw_json sub-tree),
  LibraryTracksEnvelope, TrackArtifactDto, TrackFactDto,
  OfflinePathDto, TrackRefDto. local_tracks_max_updated_ms helper
  surfaces the implicit N1-delta watermark on the SyncStateDto.
- New psysonic_library::payload module — pure
  ProgressEvent → LibrarySyncProgressPayload mapper (the
  payload Tauri events carry once PR-5b plugs the supervisor's
  mpsc receiver into AppHandle::emit). Constants for the event
  names too. Unit-testable without Tauri runtime.
- New psysonic_library::commands module with 8 #[tauri::command]
  handlers:
  - library_get_status — joins the sync_state row + the
    track-watermark MAX query into one SyncStateDto.
  - library_search — FTS5 via the existing search_tracks helper,
    paginated; hydrates hits to full LibraryTrackDto.
  - library_get_track — single SELECT through new
    TrackRepository::find_one.
  - library_get_tracks_batch — capped at 100 refs/call per spec,
    preserves caller-supplied order, drops unknowns silently.
  - library_get_tracks_by_album — ordered by
    disc/track/id via new TrackRepository::find_by_album.
  - library_get_artifact — flexible WHERE over track_artifact
    (artifact_kind required, source/format optional), latest
    fetched_at wins.
  - library_get_facts — fact_kinds filter optional;
    returns all rows for the (server_id, track_id) pair when
    none specified, sorted by fact_kind + fetched_at DESC.
  - library_get_offline_path — returns local_path with a
    `missing: true` flag when the row is absent.
- TrackRepository gains find_one / find_batch / find_by_album
  with a shared row-to-TrackRow mapper. SQL constants pinned next
  to the existing UPSERT_SQL so a schema change touches one file.
- src-tauri/src/lib.rs: LibraryStore::init in setup(), the eight
  command handlers added to invoke_handler!.

Tests cover: DTO field-name camelCase (IPC contract guard),
LibraryTrackDto round-trip through TrackRow, raw_json fallback to
Value::Null on bad input, local_tracks_max_updated_ms ignores
deleted rows, TrackRepository::find_one / find_batch / find_by_album
ordering + unknown-ref drop, ProgressEvent mapper across all six
variants + serialization keys camelCase. Library tests at 166;
workspace stays green.

Out of scope per kickoff Q1:
- Mutating commands (library_sync_*, library_patch_*,
  library_put_*, library_purge_*, library_delete_*) → PR-5b
- SyncSupervisor spawn + background scheduler tick loop +
  progress emit → PR-5b
- library_sync_bind_session / clear_session credentials → PR-5b
- TS wrappers + Settings UI + server-remove modal → PR-5c
- library_advanced_search / library_search_cross_server SQL
  builders → PR-5d

* feat(library): sync lifecycle + mutate + purge Tauri surface (Phase D1 part 2, PR-5b) (#802)

Second sub-PR of Phase D per cucadmuh's kickoff Q1 split. Adds the
mutating side of §7.1 plus the SyncSession credentials store, the
PlaybackHint setter, the orchestrator that runs InitialSyncRunner /
DeltaSyncRunner under a Tauri AppHandle and emits library:sync-progress
and library:sync-idle events, and the top-crate scheduler tick task
that sweeps every bound session through BackgroundScheduler::tick.

- LibraryRuntime extended per kickoff Q2: sync_sessions HashMap,
  playback_hint cell, current_job (cancel handle + identity), and
  scheduler_cancel flag the tick task watches. Kickoff sketch said
  Mutex<Option<SyncSupervisor>> — supervisor's join() consumes self,
  so holding it in the mutex would block library_sync_cancel behind
  the orchestrator's join; CurrentJob carries the Arc<AtomicBool>
  cancel + metadata instead, orchestrator task owns supervisor /
  receiver / join.
- New commands (spec §7.1):
  - library_sync_bind_session — caches Subsonic creds in memory,
    tries navidrome_token once for bearer cache, runs
    probe_and_persist so capability_flags reflect the live server.
  - library_sync_clear_session — drops cached credentials.
  - library_set_playback_hint — JS pushes idle / playing /
    prefetch_active from existing audio listeners.
  - library_sync_start — dispatches InitialSyncRunner (mode='full')
    or DeltaSyncRunner (mode='delta', with auto-tombstone budget
    when local/server count gap exceeds threshold). Spawns runner
    + orchestrator task that drains the progress mpsc into
    library:sync-progress emits and emits library:sync-idle when
    the runner exits.
  - library_sync_cancel — trips the current job's cancel flag.
  - library_patch_track — sparse JSON patch (starredAt, userRating,
    playCount, playedAt) per §6.5.
  - library_put_artifact / library_put_fact — upserts with
    ON CONFLICT scoped to the PK so lyrics / BPM writes survive
    re-fetches.
  - library_purge_server — transactional DELETE across the v1
    schema tables for this server_id. include_offline (default
    false) controls track_offline + bytes_freed.
  - library_delete_server_data — alias that always purges offline
    too (logout flow).
- src-tauri/src/lib.rs setup() spawns a 30 s
  MissedTickBehavior::Skip task that snapshots bound sessions and
  drives BackgroundScheduler::tick(now_ms) for each. Honours
  runtime.scheduler_cancel + the current PlaybackHint. Background
  ticks stay silent (NoopProgress) — Tauri emit for the
  scheduler path lands when Settings (PR-5c) surfaces it.
- psysonic-integration::navidrome re-exports navidrome_token so the
  bind_session command can drive the bearer cache without making
  the client module pub.

Tests cover: LibraryRuntime session round-trip (set/get/clear
scopes per server), playback_hint default + setter, snapshot
returns clones so callers can mutate freely. Existing library tests
stay green (171 → 171; new code paths under the Tauri command
surface — devtools integration smoke is PR-5c's job).

Out of scope per kickoff Q1:
- src/library/ TS wrappers + Settings UI subsection + server-remove
  modal → PR-5c
- library_advanced_search / library_search_cross_server SQL
  builders → PR-5d
- Background-tick Tauri emit (NoopProgress today) → PR-5c
- analysis_cache cross-purge in library_purge_server → PR-6

* feat(library): typed invoke wrappers + verify_integrity command (Phase D2 + part of D1, PR-5c) (#803)

Frontend-facing slice of Phase D. Ships the typed src/api/library.ts
wrapper layer that any Settings / browse code will import from, plus
the manual-integrity backend command PR-5b's review §5 note 2 called
out as missing.

Scope cut from cucadmuh's PR-5 kickoff Q1 split: that proposal had
PR-5c = D2 + D3 + D4 (wrappers + Settings subsection + server-remove
modal). The Settings UI + server-remove + audio playback-hint
wiring + authStore extensions + i18n strings turn into a thick frontend
patch in their own right; landing them in one PR with the wrappers
would mix Tauri-surface review with Settings UX review. The split:

- PR-5c (this PR) — D2 wrappers + library_sync_verify_integrity.
- PR-5c-ui (follow-up) — D3 Library Settings subsection, D4
  server-remove modal contract, playback hint feed, authStore /
  i18n.

Per kickoff exit clause ("Do not split 5c unless review size
forces it"). Reviewable as a clean Tauri-surface vs UX boundary.

- Backend: `library_sync_verify_integrity { serverId, libraryScope? }`
  command — same dispatch shape as `library_sync_start { mode:'delta' }`
  but always forces the full `DELTA_MISMATCH_CAP` tombstone budget
  regardless of the local/server count gap. Spec §6.7 Mode A user-
  initiated full reconcile bypasses the threshold check that
  governs background ticks.
  `library_sync_start` itself is refactored to delegate to a private
  `library_sync_start_inner(force_full_tombstone)` so both entry
  points share the runner-spawn + orchestrator + emit code.

- Frontend `src/api/library.ts`: full typed wrapper layer over the
  19 `library_*` Tauri commands. DTO mirrors carry the camelCase
  wire shape (`SyncStateDto`, `LibraryTrackDto`, `TrackArtifactDto`,
  `TrackFactDto`, `OfflinePathDto`, `PurgeReportDto`, `SyncJobDto`,
  `TrackRefDto`, `ArtifactInputDto`, `FactInputDto`). Plus the
  `LibrarySyncProgressPayload` / `LibrarySyncIdlePayload` interfaces
  and `subscribeLibrarySyncProgress` / `subscribeLibrarySyncIdle`
  helpers that wrap `@tauri-apps/api/event` listen. PlaybackHint
  literal type lives here too (`'idle' | 'playing' | 'prefetch_active'`)
  so the audio listeners in PR-5c-ui can import a single source of
  truth.

- `src-tauri/src/lib.rs` adds the new verify_integrity handler to
  the `invoke_handler!` aggregate.

Tests: library tests stay at 171 — verify_integrity is exercised
through the existing `sync_start_inner` paths; the wrapper layer is
trivial passthrough that TypeScript types already check. Vitest
coverage for the typed wrappers belongs with PR-5c-ui where there
are real consumers (LibraryTab) to drive integration tests.

PR-5c-ui (next) lands:
- Library Settings subsection (§7.3 minus advanced toggles)
- ServerRemoveModal extension (keep vs delete local index per §5.6)
- authStore: libraryIndexEnabledByServer + auto-reconcile toggle
- src/store/audioListenerSetup audio:playing / ended /
  setDeferHotCachePrefetch → library_set_playback_hint
- i18n keys for the new strings

* feat(library): Settings library index UI + playback hint + purge-on-remove (Phase D3/D4, PR-5c-ui) (#804)

* feat(library): Settings library index UI + playback hint + purge-on-remove (Phase D3/D4, PR-5c-ui)

Frontend half of Phase D, on top of PR-5c's typed wrappers. Wires the
Settings → Library subsection (§7.3), the audio playback-hint feed
(§6.2.4), and the server-remove keep-vs-delete choice (§5.6).

- New libraryIndexStore (Zustand, persisted) — per-server enable flag
  + auto-reconcile toggle. Kept out of authStore so the index feature
  evolves independently and the persisted blob stays small.
- New LibraryIndexSection in Settings → Library:
  - Per-server "Enable local library index" toggle → binds /
    clears the Rust sync session with the active server's
    credentials. Off by default (P6).
  - Read-only status (Idle / Checking / Initial sync / Ready (n) /
    Error) polled from library_get_status every 3 s, overlaid with
    live library:sync-progress events.
  - Sync now / Verify integrity / Cancel buttons. Verify runs one
    §6.7 pass (budget 200) per click; the status line shows the
    checked/removed counts so large libraries can be continued with
    another click (auto-resume loop is a follow-up).
  - Auto-reconcile toggle.
  - Subscribes to library:sync-progress + library:sync-idle for the
    active server; errors surface as a toast.
- Audio playback hint: handleAudioPlaying → 'playing',
  handleAudioEnded → 'idle' via notifyLibraryPlaybackHint, which
  gates on the per-server index toggle + dedupes repeated hints so
  the IPC boundary isn't spammed on every progress tick.
- ServersTab delete flow: when a server with an enabled index is
  removed, a second confirm offers keep-vs-delete of the local
  library cache (OK = library_delete_server_data, Cancel = retain
  for offline). Always clears the sync session.
- i18n: en + de keys for the new strings; other locales fall back
  to en via i18next (later sweep).

Per PR-803 review §5: verify-integrity resume UX is one-pass-per-click
with a visible counter; sync_start idempotency (replaces in-flight)
is surfaced via the Cancel button appearing while busy.

Out of scope:
- VirtualSongList / playerStore local-mode consumers → PR-7 (F1/F3/F5)
- library_advanced_search / cross-server UI → PR-5d + PR-7 F2
- Auto-resume loop for very large verify-integrity runs → follow-up
- Search-all-servers + threshold input (advanced §7.3) → later

* fix(library): normalize server base URL before bind probe

The bind toggle threw "subsonic transport: builder error | relative
URL without a base" — `server.url` is stored bare (e.g.
`nas.example.com`) and reqwest needs a scheme. Two-sided fix:

- Frontend: LibraryIndexSection passes `authStore.getBaseUrl()`
  (adds http:// + strips trailing slash) instead of the raw
  `server.url`, matching the existing `subsonic.ts` convention.
- Backend: `library_sync_bind_session` normalizes the incoming
  `base_url` defensively so the stored session + every downstream
  caller (sync_start, scheduler tick, navidrome_token) gets a
  scheme-qualified URL regardless of what the WebView sends.

Tests: normalize_base_url covers bare host, trailing slash, existing
http/https scheme, and whitespace.

* fix(library): re-bind sync session on startup + server switch

"Library sync failed: no bound session" — the per-server index toggle
persists in localStorage but the Rust sync session (credentials +
bearer) lives in process memory and is gone after an app restart, so
the toggle showed "on" while no session existed. Per PR-5 kickoff Q5
("on server connect if index already on").

- New `ensureActiveServerSessionBound()` helper: re-binds the active
  server's session when its index toggle is enabled. Best-effort —
  silent on failure (Settings surfaces the real error on explicit
  toggle).
- MainApp re-binds on every `activeServerId` change (covers app
  startup + server switch — `setActiveServer` drives the effect).
- LibraryIndexSection re-binds on mount before the first status poll,
  so Sync now / Verify integrity work immediately even when the
  toggle was already on from a previous run.

* fix(library): trigger initial full sync on first enable (PR-804 review §5.1)

cucadmuh's PR-804 review flagged this as release-blocking: the toggle
only bound the session and «Sync now» / the background tick ran
delta-only, so a fresh enable left the index empty — delta can't
populate a never-synced library.

- On first enable, after bind, fetch status and dispatch
  `library_sync_start { mode: 'full' }` when `lastFullSyncAt` is null
  (matches spec §6.2 "initial sync always background").
- «Sync now» now picks mode adaptively: `full` until a full sync has
  completed, `delta` afterward — so the button works both for the
  initial population and incremental updates.

Other PR-804 review notes (auto-reconcile toggle → backend wiring,
prefetch_active hint, clear-old-session-on-switch) stay as documented
non-blocking follow-ups.

* feat(library): advanced search + cross-server SQL builders (Phase D-search, PR-5d) (#806)

* feat(library): advanced search + cross-server SQL builders + commands (Phase D-search, PR-5d)

- FilterFieldRegistry SQL resolution: SqlFragment, compare_fragment, validate_for_entity (§5.13.5)
- Advanced Search builder: per-entity track/album/artist queries; genre (case-insensitive), year, starred, bpm filters; bpm dual-storage resolution (§5.13.4); libraryScope; sort allowlist; full-match totals
- Cross-server FTS union (§5.5B / §5.9 A') with canonical-id dedup
- library_advanced_search + library_search_cross_server commands, registered in the shell

* feat(library): typed advanced search / cross-server invoke wrappers (PR-5d)

Mirror request/response DTOs and add libraryAdvancedSearch / librarySearchCrossServer
in src/api/library.ts. UI parity (AdvancedSearch.tsx) stays PR-7.

* fix(library): self-heal stale/unreadable initial-sync cursor instead of bricking (#807)

The initial-sync cursor records the ingest strategy it was created under.
When a re-probe later selects a different strategy (e.g. the Navidrome
native bearer is briefly unavailable, downgrading N1->S2), the cursor guard
returned a hard error — and since nothing clears the cursor, every later
full sync failed with no recovery path.

Reset the stale (or unreadable) cursor and start fresh under the selected
strategy instead of erroring. Re-ingest is idempotent (upsert); the
tombstone pass reconciles leftovers.

* fix(library): emit per-batch progress during initial sync (#808)

The initial-sync runner only emitted PhaseChanged (start) and Completed
(end), so the Settings status sat at "initial_sync" with no count for the
entire ingest — looking stuck on large libraries even while rows landed.

Emit IngestPage per batch from the N1/S1/S2 loops with the running ingested
total; the existing <=2 Hz throttle paces it. The frontend already renders
the count from these events.

* feat(library): Advanced Search reads the local index when ready (Phase F2, PR-7a) (#811)

When the active server's index is fully synced, Advanced Search serves
query / genre / year / result-type from library_advanced_search (instant +
offline) and pages songs locally. On not-ready or any failure it falls back
to the existing network path unchanged (spec 5.13.6). Results map from each
entity's stored Subsonic rawJson, with the flat hot columns as a fallback.

* feat(library): canonical matcher — link tracks by ISRC/MBID on ingest (Phase H1/H2, PR-4a) (#812)

Adds the strong-key cross-server matcher (spec §5.5A): on every track upsert,
link (server_id, track_id) to a canonical id derived from its ISRC (preferred)
or MBID recording. Deterministic id (`{kind}:{value}`) keeps it O(1) and
idempotent — no lookup-then-create race, no fuzzy loop on the bulk path.
Tracks without a strong key stay standalone (fuzzy/search-time matching is H3).

* feat(library): cross-server fuzzy fallback in search (Phase H3, PR-4b) (#813)

library_search_cross_server now returns a `fuzzy` list alongside the exact
FTS `hits` (spec §5.9): per-server `title LIKE %query%` for matches the exact
pass missed (diacritics, partial words), capped per server, excluding exact
hits and deduped by canonical id against them. Shared `like_contains` moved
to the `search` module.

* feat(library): FactRepository with TTL + provenance rules (Phase E4, PR-6a) (#814)

Typed CRUD over track_fact behind library_get_facts / library_put_fact
(spec §5.12): get lazily deletes the track's expired facts then returns the
survivors (no background GC, P34); a `user` bpm fact also writes the hot
track.bpm column so the override wins and survives a resync (R6-3.4). The
commands now delegate here instead of inlining the SQL.

* feat(library): ArtifactRepository with TTL + 512KB cap (Phase E4, PR-6b) (#815)

* fix(integration): decode OpenSubsonic isrc string-array on Song (#818)

OpenSubsonic types `isrc` as `string[]`; Navidrome 0.61.2 ships it as
`isrc: []` or `["USRC…"]`. The typed `Song.isrc: Option<String>` could
not decode either form, which broke the S1 (`search3`) and S2
(`getAlbum`) ingest paths on real Navidrome libraries — initial sync
could not complete past the first array-valued track.

Add a tolerant `de_string_or_seq` deserializer: plain string →
`Some`, non-empty array → first usable value (string element, or an
object element's `name` for the `[{ "name": … }]` shape), `[]`/null →
`None`. The full multi-value set still survives verbatim in
`track.raw_json` (ADR-7). Applied to `Song.isrc`.

Per maintainer policy R7-15 (workdocs question
2026-05-20-large-library-ingest-client-only, checklist item 1):
treat Navidrome as a black box, harden the client decode.

Tests cover `isrc: []` → None, populated array, and the legacy
single-string form.

* feat(library): large-library ingest strategy — S1 over N1 (R7-15) (#819)

Per maintainer policy R7-15 (large-library ingest, client-only): very
large Navidrome catalogs must not start initial sync on N1 — its native
`/api/song` returns HTTP 500 beyond a deep offset and can never finish.
S1 (`search3`) does not hit that wall.

- Add `IngestStrategy::select_initial_strategy(flags, server_track_count,
  n1_bulk_unreliable)`. Large libraries (count > LARGE_LIBRARY_THRESHOLD,
  default 40_000) or servers flagged `n1_bulk_unreliable` route to S1 — or
  S2 when search3 bulk is absent. Normal-size libraries keep the cheapest
  N1 → S1 → S2 chain unchanged.
- Persist the learned per-server `n1_bulk_unreliable` flag on `sync_state`
  (additive migration 002, DEFAULT 0). The mid-run N1→S1 fallback that
  sets it lands in a follow-up.
- Capture `getScanStatus.count` in the capability probe and persist it as
  the `server_track_count` watermark, so the threshold applies from the
  first sync rather than only after N1 hits the wall once. A count-less
  probe never clobbers a watermark from a prior run.
- The initial-sync runner now selects via the new policy.

Tests: selector table (all branches incl. threshold boundary and the
search3-absent fallback), repo flag roundtrip, probe count capture +
watermark-preservation, migration head-version bookkeeping.

* feat(library): freeze ingest strategy on resume (R7-15 Q3) (#820)

A persisted initial-sync cursor that has already made progress must resume
under its own strategy and ignore what a fresh capability probe would now
pick. Previously any strategy mismatch reset the cursor to a fresh one — so
a flapping Navidrome bearer (N1 flag toggling between probes) restarted
ingest from offset 0 on every launch, which is why large initial syncs
never completed across restarts.

`load_or_init_cursor` now:
- resumes the cursor's strategy when it has progress (`ingested_count > 0`
  or `phase != Ingest`), regardless of the re-selected strategy;
- adopts the freshly-selected strategy only when there is no resumable
  progress (offset 0), where re-selecting costs nothing;
- still resets a corrupt/unreadable cursor rather than hard-erroring.

One guarded exception: a cursor still on N1 after the server was learned
`n1_bulk_unreliable` is known-broken and re-selects onto the non-N1 path
instead of resuming a wall-bound N1 loop (the mid-run N1→S1 fallback that
preserves progress lands next).

Tests: resume-with-progress freezes strategy and keeps the count;
no-progress cursor adopts the re-selected strategy; known-broken N1 cursor
re-selects; unreadable cursor still resets.

* feat(library): one-way N1→S1 fallback on deep-offset 500 (R7-15 Q5) (#821)

When the N1 ingest loop hits a persistent HTTP 500 at or beyond the
deep-offset safety line (`N1_DEEP_OFFSET_SAFE`, 50_000) it now treats it
as Navidrome's server-side deep-offset wall rather than a transient error:
it learns `n1_bulk_unreliable` for the server and finishes the sync on S1.

- `run_n1` catches the wall after retry exhaustion (`n1_hit_deep_offset_wall`:
  HTTP 500 AND offset >= the safety line) and hands off to `fall_back_n1_to_s1`.
  A 500 below the line stays a propagated error — no silent downgrade.
- The fallback flags the server, then restarts S1 from offset 0. N1 (`id ASC`)
  and S1 (`search3` default order) don't share an offset space, so resuming
  from the N1 offset would skip songs; re-ingest is idempotent (PK upsert),
  duplicate work over the rows N1 already wrote is acceptable for v1. The
  cursor is rewritten in place, never zeroed.
- One-way only: S1 never flips back to N1 mid-run. Combined with the
  persisted flag and the resume freeze, a future sync selects S1 directly.
- `N1_DEEP_OFFSET_SAFE` is overridable on the runner so the fallback is
  testable without 50k rows of fixture data.

Tests: deep-offset 500 falls back to S1, ingests the full set without
duplicating N1's rows, and persists the flag; a shallow 500 propagates and
does not flag the server.

* feat(library): cache + retry Navidrome bearer, keep N1 flag on transient loss (R7-15 Q3) (#822)

A flaky `/auth/login` previously stripped N1 for a whole bind: the bearer
was fetched once, best-effort, and a single miss dropped to Subsonic-only.
Per R7-15 Q3 a transient `navidrome_token` failure must not drop the
`NavidromeNativeBulk` capability.

- `bind_session` fetches the bearer with `navidrome_token_with_retry`
  (3 attempts, short backoff); if it still fails, it keeps the bearer
  cached from a prior bind instead of overwriting it with `None`. The token
  / credentials are never logged.
- `probe_and_persist` preserves a previously-learned `NavidromeNativeBulk`
  flag when it probes without a token — the server still supports
  `/api/song`; only the bearer is missing this bind. The capability is a
  stable server property, so a token-less probe must not clear it.
- `library_sync_start_inner` masks `NavidromeNativeBulk` from *this run's*
  strategy selection when the session has no token, so the run proceeds
  Subsonic-only (S1/S2) instead of selecting N1 with no creds. The
  persisted capability stays intact for a later bind that recovers the
  token. The in-flight cursor is already protected by the resume freeze.

Tests: token retry yields the token on success and `None` after exhausting
attempts; the probe keeps a learned N1 flag across a token-less re-probe.

* feat(library): mid-run S1→S2 fallback on persistent S1 failure (R7-15 Q8) (#823)

The N1→S1 fallback (#821) had no analogue when S1 itself fails on a server.
Per R7-15 Q8, a persistent S1 failure (C12 retries already exhausted) must
fall back to the universal S2 album crawl — no new artist-walk strategy.

- `run_s1` catches a persistent fetch failure from the `search3` retry loop
  (`is_fetch_failure`: transport / HTTP / decode / Subsonic API / not-found)
  and hands off to `fall_back_s1_to_s2`. Cancellation and storage errors
  propagate untouched.
- The fallback restarts S2 from scratch. S1 (`search3` order) and S2
  (album-list order) don't share an offset space, so resuming from the S1
  offset would skip songs; re-ingest is idempotent (PK upsert). The cursor is
  rewritten in place, never zeroed — the resume freeze then keeps the run on
  S2 across restarts.

This completes the ingest fallback chain N1→S1→S2 from the §6.3 strategy
order; the start-time "no search3 → S2" selection was already covered (#819).

Tests: a persistent S1 500 falls back to S2 and the album crawl ingests the
track.

* fix(library): resume interrupted initial sync on startup (#824)

* fix(library): resume interrupted initial sync on startup

An initial sync killed mid-run (app restart) sat at `idle` until the user
clicked «Sync now» — the background scheduler is delta-only and the
auto-full-sync only fired on the index toggle, not on the startup re-bind.

`resumeInitialSyncIfIncomplete` runs after the active server's session is
re-bound (startup + server switch): if no full sync has completed yet
(`!lastFullSyncAt`) it dispatches `library_sync_start { mode: 'full' }`,
which resumes from the persisted cursor instead of restarting from zero.
Once a full sync has landed it is a no-op, so delta stays the scheduler's
job. Best-effort — errors stay silent (Settings surfaces them on explicit
action).

Tests: starts a full sync when none has completed, no-ops once a full sync
has landed, stays silent when the status lookup fails.

* fix(library): silence cancelled-sync toast, de-dupe startup resume

Two rough edges from the startup resume:

- A cancelled sync surfaced as «Library sync failed: sync cancelled». The
  orchestrator emitted the runner's `Cancelled` result as an error on the
  sync-idle event. Cancellation is expected — the user cancelled, or a newer
  `library_sync_start` superseded the job (server switch / startup resume) —
  and is documented as silent. `sync_outcome_to_result` now maps
  `SyncError::Cancelled` to a clean idle, only real errors toast.
- `resumeInitialSyncIfIncomplete` is now de-duped per server. React
  StrictMode fires the startup effect twice, so a second `library_sync_start`
  cancelled the first (`set_current_job` is cancel-and-replace) — harmless
  with the fix above, but the dedupe avoids the wasted job + probe entirely.

Tests: `sync_outcome_to_result` keeps `Cancelled` silent and forwards real
errors; concurrent resume calls start a single full sync.

* fix(library): run DB read commands off the main thread (async) (#825)

The 10 library read commands were synchronous (`pub fn`). Per the Tauri v2
docs, commands without `async` run on the main thread — so a read that
blocks freezes the UI. During an initial sync the runner holds the single
`Mutex<Connection>` for a whole batch write (500 rows × per-row remap on
Navidrome + upsert + FTS, one transaction), and the Settings library
section polls `library_get_status` on an interval. Each batch write blocked
that polled read on the main thread → the window greyed out until the batch
finished, with the freeze growing as the DB grew.

Make the DB-touching read commands `async` so they run off the main thread:
`library_get_status`, `library_search`, `library_get_track`,
`library_get_tracks_batch`, `library_get_tracks_by_album`,
`library_get_artifact`, `library_get_facts`, `library_get_offline_path`,
`library_advanced_search`, `library_search_cross_server`. Reads still
serialize behind the writer (the single connection is intentional — the
schema mirrors `analysis_cache`, spec §5.1), but the wait no longer blocks
the UI. State-only commands stay sync. Invoke names / payloads are
unchanged, so the frontend is unaffected.

Spec §15 R7-15 follow-up — surfaced in live QA on a 170k library.

* feat(library): scope analysis cache by server_id (E1, schema only) (#826)

Add a versioned migration to audio-analysis.sqlite so waveform/loudness
rows are keyed per server. This is the schema-only step (PR-6c-1): every
existing row migrates to server_id='' and behaviour is unchanged. The
server_id write/read wiring, legacy fallback and lazy re-tag follow in 6c-2.

- migrations 001 (baseline = the pre-versioning schema) + 002 (rebuild the
  three tables with server_id; PK (server_id, track_id, md5_16kb), loudness
  + target_lufs)
- versioned runner mirroring the library store; each migration commits its
  schema change and version marker in one transaction, so a failure or crash
  rolls the whole migration back and retries cleanly
- VACUUM INTO snapshot before the table rewrite as a safety net beyond the
  transaction (disk-full at COMMIT, FS corruption)
- TrackKey gains server_id; all callers pass "" for now

* feat(library): analysis cache server_id wiring (E1, 6c-2) (#827)

* feat(library): scope analysis cache writes/reads/deletes by server_id (E1 wiring)

Build on the 6c-1 schema migration: thread the playback server scope
(playbackServerId ?? activeServerId) through the analysis cache so a server
switch can no longer surface another server's waveform/loudness for the same
bare track_id.

- Write: seed_from_bytes_* and the CPU-seed / HTTP-backfill queues carry a
  server_id; every audio write path (in-memory, ranged, legacy stream, local
  file, spill, preload), the syncfs offline/hot caches, and the backfill
  command write under the playback server (empty = legacy '').
- Read: get_latest_*_for_track and the exact-key lookup try the server scope
  first, then fall back to the legacy '' rows; a legacy hit is re-tagged onto
  the server scope (INSERT OR IGNORE, never clobbers a precise row). No bulk
  backfill — existing caches re-tag lazily on play, so they are not
  re-analysed wholesale.
- The backend gain-resolution path (loudness normalization, replay-gain
  updates, device resume) is scoped via a pinned current_playback_server_id on
  the audio engine, so normalization keeps working for server-scoped rows.
- Delete: delete_*_for_track_id scope to (server + legacy ''); reseed on one
  server no longer wipes another server's analysis. delete_all_waveforms stays
  global (Settings -> Storage).

Tauri boundary: analysis_get_waveform(_for_track), analysis_get_loudness_for_track,
analysis_delete_waveform/loudness_for_track and analysis_enqueue_seed_from_url
gain an optional serverId; audio_play and audio_preload gain an optional
serverId. All additive (absent = legacy '').

* feat(library): pass playback serverId to analysis IPC (E1 wiring)

Send getPlaybackServerId() (queueServerId ?? activeServerId) with every
analysis-cache call so reads/writes/deletes scope to the right server:

- audio_play / audio_preload (playTrack, resume, queue-undo restore, gapless
  byte-preload)
- analysis_get_waveform_for_track / analysis_get_loudness_for_track (waveform +
  loudness refresh)
- analysis_delete_waveform/loudness_for_track + analysis_enqueue_seed_from_url
  (reseed + loudness backfill)

Absent serverId stays backward-compatible (legacy '' scope).

* feat(library): content_hash from playback (E2, 6d) (#828)

* feat(library): record playback content_hash into the track store (E2)

Bridge the playback-derived md5_16kb into library `track.content_hash` (R7-16 Q4)
so id-remap can rebind a track when the server reassigns ids (§6.9).

- New `ContentHashSink` port in psysonic-core (closure handle, mirrors
  PlaybackQueryHandle): keeps psysonic-analysis decoupled from psysonic-library.
- `seed_from_bytes_into_cache` returns the computed md5; `seed_from_bytes_execute`
  fires the sink after a successful seed (Upserted or cache-hit) when a real
  server is known. The shell crate registers the sink to patch the library.
- `patch_content_hash` + `library_patch_track`'s new optional `contentHash`
  field write it; both no-op when the library has no row for (server_id, id),
  i.e. the index is off for that server.
- Sync upsert no longer clobbers it: `content_hash = COALESCE(NULLIF(
  excluded.content_hash,''), track.content_hash)` — a sync (which passes NULL)
  preserves the playback hash, a non-empty incoming hash still wins.

No schema migration — the `content_hash` column already exists. Tauri boundary:
`library_patch_track` gains optional `contentHash` (additive).

* feat(library): expose contentHash on libraryPatchTrack wrapper (E2)

Add optional `contentHash` to the `libraryPatchTrack` patch type so the TS
contract matches the extended Rust command. Normally written by the Rust
analysis bridge; exposed for completeness.

* feat(library): enrichment summary on library_get_track (E3, 6e) (#829)

* feat(library): enrichment summary on library_get_track (E3)

Add an optional `enrichment { waveformReady, loudnessReady, lyricsCached }` to
the single-track `library_get_track` read (R7-16 Q5). Read-only, per-server,
never blocks on the network; list/batch projections leave it unset.

- New `AnalysisReadinessQuery` port in psysonic-core (closure handle, mirrors
  ContentHashSink) keeps psysonic-library decoupled from psysonic-analysis. The
  shell crate registers it to probe the analysis cache by exact
  (server_id, track_id, content_hash) key with legacy '' fallback — read-only,
  no re-tag. waveform/loudness readiness is gated on a known content_hash (E2).
- `lyricsCached` from a new pure-read `ArtifactRepository::lyrics_cached`
  (valid, non-expired, non-not_found lyrics row).
- `library_purge_server`'s `includeAnalysis` documented as a deliberate v1
  no-op (R7-16 Q7): analysis is never deleted on purge / server remove.

Tauri boundary: `LibraryTrackDto` gains optional `enrichment` (additive).

* feat(library): mirror enrichment on LibraryTrackDto wrapper (E3)

Add `TrackEnrichmentDto` + optional `enrichment` to the TS `LibraryTrackDto` so
the contract matches the extended `library_get_track` response.

* feat(library): VirtualSongList browses the local index when ready (F1) (#830)

The all-songs browse now serves pages from the local library index when it is
ready for the active server, falling back to the unchanged network path
otherwise.

- `runLocalSongBrowse` (reuses the F2 local-read adapters): empty-query
  browse-all via `library_advanced_search`, whose default track order
  (`t.title COLLATE NOCASE ASC`) matches the network `ndListSongs('title','ASC')`
  path, so paging stays coherent across a local↔network boundary.
- Gated per page on `libraryIsReady` + `source === 'local'`; any miss / failure
  returns null → VirtualSongList uses the existing browse path unchanged.
- Search (non-empty query) stays on the network path for now; rich search is
  already covered by Advanced Search (F2).

* feat(library): patch-on-use for star/rating/scrobble (PR-7 F3) (#831)

* feat(library): library_patch_track clears nullable fields on explicit null (F3)

Extract the patch logic into a testable `apply_track_patch`. Nullable integer
fields (`starredAt` / `userRating` / `playCount` / `playedAt`) now distinguish an
absent key (leave untouched) from an explicit `null` (clear the column), so
`unstar` ({ starredAt: null }) actually un-stars the local row. `.map` keeps the
present/absent distinction; `as_i64()` yields the value or `None` → bound as SQL
NULL. F3 is the first caller that sends null, so no existing behaviour changes.

* feat(library): patch-on-use wiring for star / rating / scrobble (F3)

After a successful star/unstar, setRating, or play scrobble, mirror the change
into the local library index via `library_patch_track` so its reads (browse F1,
advanced search F2) reflect the action immediately — no stale list after a rate,
no full resync.

- `patchLibraryTrackOnUse` helper: fire-and-forget, gated on the index being
  enabled for the server; the Rust command additionally no-ops when no row
  matches (album/artist id, or index off).
- Wired at the central API chokepoints: `star`/`unstar` (song only) →
  `starredAt`, `setRating` → `userRating`, `scrobbleSong` → `playedAt`.
- `play_count` is left to the next sync (the patch sets absolute values; a
  correct increment needs the current base).

F4 (deprecating the player-store override maps) is intentionally separate —
removing them would break instant star feedback when the index is off.

* feat(library): full-queue restore from the index on startup (PR-7 F5) (#832)

Persist the whole queue as a lightweight ref list and rehydrate it from the
local index on startup, so the entire queue survives a restart instead of only
the windowed slice (R7-17 / §8.6).

- Persist adds `queueRefs` (full ordered ids) + `queueRefsIndex` alongside the
  existing windowed `queue`. Ids are tiny; the windowed objects stay as the
  no-index fallback.
- `hydrateQueueFromIndex` (startup, after session bind): when the library index
  is ready for the queue's server, hydrate the full queue via
  `library_get_tracks_batch` (batched ≤100), map `songToTrack ∘ trackToSong`,
  re-locate the current track so `queueIndex` stays aligned, then clear the refs.
- Index not ready / missing rows / current track not found → keep the windowed
  fallback (queue never empty when the index is off, the P6 default). Old
  persisted shape without refs loads unchanged.
- `trackToSong` exported from the F2 local-read adapters (one mapper).

Kept the windowed-objects persist (did not drop the cap per R7-17 note): the
index-off default needs the embedded fallback or the queue would restore empty.

* feat(library): pending-sync for song star/rating (PR-7 F4) (#833)

* feat(library): central pending-sync helper for song star/rating (PR-7 F4)

`queueSongStar` / `queueSongRating` (spec §6.5 / R7-18): set the player-store
override optimistically, retry the Subsonic API with exponential backoff (flush
on `online` / window focus), and on success clear the override + patch the
in-memory Track so the UI stays correct without it. The F3 index patch-on-use
runs inside the API layer, unchanged.

- No rollback on the first network error (the override survives until the retry
  succeeds or the app restarts; overrides are session-only, not persisted).
- Latest-toggle-wins coalescing + an identity guard so a fast re-toggle while a
  request is in flight can't retire the newer task.
- v1: songs only.

* feat(library): route song star/rating through the pending-sync helper (PR-7 F4)

Replace the scattered optimistic-set + API-call + rollback logic with the single
`queueSongStar` / `queueSongRating` helper across cucadmuh's named v1 surfaces:
PlayerBar, FullscreenPlayer, MobilePlayerView, both context menus (song + queue
row), both shortcut paths, the song-rating hook + player-bar stars, skip→1★, and
AlbumDetail (song star + rating). The 30+ override read sites are unchanged —
they already read `override ?? track`, and the override now clears on success.

Standalone page toggles (Favorites, RandomMix, NowPlaying star) and the separate
mini-player webview keep their existing path — no regression (a non-migrated
override simply lingers as before) — and move to a follow-up.

* feat(library): route remaining song star/rating sites through pending-sync (F4 follow-up) (#834)

Migrate the three standalone song write sites left out of #833 onto the
central queueSongStar / queueSongRating helper:

- Favorites: handleRate + removeSong (un-star)
- RandomMix: toggleSongStar (drops local try/catch rollback per no-rollback policy)
- useNowPlayingStarLove: toggleStar (keeps local view state, helper owns override + retried sync)

MiniContextMenu stays on its direct path (separate webview, no shared store).
No behaviour change for album/artist rating paths.

* feat(library): route playlist song star/rating through pending-sync (F4 follow-up) (#835)

The playlist-detail star/rating hook was the last shared-store song write
site still calling the Subsonic API directly. Route handleRate +
handleToggleStar through queueSongRating / queueSongStar, matching the
Favorites and RandomMix follow-ups; keep the local ratings/starredSongs
view state, drop the inline override.

MiniContextMenu remains on its direct path (separate webview).

* feat(library): BPM range filter UI in Advanced Search (PR-7 F6) (#836)

* feat(library-sync): parallel initial ingest (S2 + N1/S1 prefetch)

Wire C11 ParallelismBudget (max 4 when idle) into InitialSyncRunner:
parallel getAlbum for S2, up to 4 in-flight pages for N1/S1, and persist
S2 cursor once per album-list page instead of per album.

* fix(library-sync): defer scheduler during initial sync and improve ingest diagnostics

Background delta/tombstone ticks every 30s were competing with IS-3 bulk ingest
for the write mutex (20–60s lock waits on large libraries). Skip scheduler while
sync_phase is initial_sync/probing or bulk ingest is active.

Serialize ingest batch metrics as camelCase for DevTools, add bulk-ingest FTS/index
suspension, combined cursor persist, write-op tracing, live local search, and
library dev logging helpers.

* fix(library-search): scoped FTS, cancel stale live search, skip 1-char queries

Use column-scoped FTS for artists/albums/songs, min two graphemes for local
FTS, capped match counts in Advanced Search, and title browse index (m004).

Live Search aborts superseded network requests, passes requestEpoch to drop
stale Rust FTS, and avoids search3 fallback for too-short queries.

* fix(library-search): prefix FTS, fast subquery joins, hide BPM in Advanced Search

Live and Advanced Search now use FTS5 prefix tokens ("metal"*) and limit
bm25 ranking inside rowid subqueries so large libraries stay in the ms range.
Advanced Search BPM filter is removed from the UI until enrichment ships.

* feat(library-search): race local index vs search3, show first result

Live Search and Advanced Search text queries run library and network
backends in parallel; the faster source wins. Adds searchRace helper
and search_race dev logging.

* feat(library-index): multi-server UI, serial sync queue, scoped local search

Add master library index toggle with per-server rows, offline retry, and a
frontend sync queue so initial ingest runs one server at a time. Scope Live
Search and Advanced Search to the sidebar music library filter via library_id
and raw_json fallbacks; coerce numeric libraryId on ingest. Promote idle sync
state to ready when a full sync stamp exists and block cross-server initial
sync starts in Rust.

* chore(library-store): compliance — clippy, i18n, CHANGELOG

Fix clippy/tsc blockers (request structs, IngestPageCtx, type aliases),
add library index strings to all 9 locales, and document the preview
feature in CHANGELOG [1.47.0] with Psychotoxical + cucadmuh attribution.

* docs(credits): library index preview contributions

Credit Psychotoxical for the local library store foundation and cucadmuh
for multi-server UI, scoped search, and i18n. Drop removed scan-trigger
wording from PR #780 entry.

* docs(release): link library index preview to PR #846

* docs(changelog): sort [1.47.0] entries by ascending PR number

* docs(changelog): mark library index as Added in [1.47.0]

* docs(changelog): restructure [1.47.0] into Added/Changed/Fixed

Match 1.46.0 layout: new features in Added (incl. library index),
enhancements in Changed, bug fixes in Fixed — PR ascending within each block.

* fix(library): address PR #846 review — delta guard + FTS order

Skip background scheduler delta when LibraryRuntime already has a
foreground sync job for the same server. Preserve bm25 rowid ordering
in live search track/artist/album fetches.

* fix(library): address remaining PR #846 review items

S2 resume persists current_album_id per album; same-server resync awaits
the previous runner. N1 delta watermark uses strict less-than; Navidrome
HTTP 500 detection is structured. Adds genre/year indexes, backoff jitter
salt, LiveSearch failure toast, and user-facing search badge copy.

* fix(library): close resync notify race and tighten FTS trigger test

Use notify_one() so an early runner completion cannot lose the drain
signal before same-server full resync awaits. FTS test now compares
normalized trigger bodies from migration vs suspend/restore roundtrip.

cucadmuh 70c2fdfbf9 Linux: session-native GDK/WebKit mitigations and in-page browse scroll (#731)
* feat(linux): session GDK defaults, nvidia-quirk, optional x11-legacy wrap

Ship PSYSONIC_ALLOW_NATIVE_GDK from Nix/AUR instead of pinning WEBKIT_DISABLE_*
and GDK x11. Add flake psysonic-x11-legacy for the old wrap; alias gdk-session
to psysonic. Startup uses webkit2gtk-nvidia-quirk and Wayland-aware compositing;
refresh Help (a45) and nixos-install docs.

* fix(linux): session GDK and nvidia-quirk only; drop wrapper env heuristics

Remove PSYSONIC_ALLOW_NATIVE_GDK and devShell GDK/WEBKIT exports; stop
synthesizing GDK/WebKit vars in main.rs. Update Nix/AUR wrappers, install
docs, CHANGELOG, and help FAQ with practical user-facing workarounds.

* fix(linux): X11-pinned GDK uses DMABUF quirk path, not Wayland explicit-sync

When GDK_BACKEND is forced to x11 on a wayland user session, webkit2gtk-nvidia-quirk
would still apply __NV_DISABLE_EXPLICIT_SYNC and gray out the webview. Map that case
to WEBKIT_DISABLE_DMABUF_RENDERER like native X11.

* fix(ui): stabilize WebKitGTK/Wayland hover paint for nav and media cards

Sidebar nav links avoid transition:all and promote icons with translateZ(0).
Artist rows and album/artist/song cards use compositing hints; card shadows
and borders no longer interpolate so cover zoom can stay smooth without jitter.

* fix(ui): isolate artist/album card text and cover paint on WebKitGTK

Promote cover blocks with contain/paint and text stacks with translateZ(0);
use artist-card-info on the artists grid for the same layout as other cards.

* feat(artists): in-page overlay scroll and locked main viewport

Move list/grid into an inner OverlayScrollArea, stop sticky toolbar from
owning the route scroll, align the rail with the main panel edge, and skip
the main-route overlay thumb when the viewport cannot scroll vertically.

* feat(browse): extend in-page overlay scroll to more library routes

Reuse the locked main viewport pattern from Artists for Albums, Composers,
Lossless albums, and New releases; wire VirtualCardGrid and scroll chrome
to the matching in-page viewport ids.

* fix(linux): improve Wayland GPU compositing text clarity in WebKitGTK

Use on-demand hardware acceleration on main and mini webviews when the
session is Wayland and compositing stays on; gate subpixel body AA on the
same conditions via new Tauri probes. Document PSYSONIC_SKIP_WAYLAND_FONT_TUNING
for opt-out and changelog.

* fix(rust): satisfy clippy needless_return in Linux webkit helpers

* fix(linux): tune Wayland text rendering with HW policy env and CSS

Allow PSYSONIC_WEBKIT_WAYLAND_HW_POLICY to select WebKit hardware
acceleration policy (never/always vs default on-demand). Extend Wayland
font CSS to #root with geometricPrecision and text-size-adjust on html.

* feat(linux): Wayland text presets in settings, safe WebKit apply, CPU default

Persist profile to app config; apply WebKit policy at startup/mini only to
avoid WebKitGTK hangs on live toggles. UI + CSS preview stays live; default
preset is sharp (CPU-friendly).

* fix(linux): map Wayland sharp preset to OnDemand WebKit policy

HardwareAccelerationPolicy::Never at startup broke main-viewport wheel
scrolling on WebKitGTK+Wayland; sharp vs balanced remains a CSS AA path.
Use PSYSONIC_WEBKIT_WAYLAND_HW_POLICY for a true Never policy.

* fix(rust): gate Linux-only Wayland WebKit helpers for Windows builds

Re-export startup helpers only under cfg(linux) and drop non-Linux stubs so
Windows compiles without unused-import and dead-code warnings.

* chore(release): CHANGELOG + credits for Linux session/WebKit work (PR #731)

Consolidate scattered incremental changelog notes into two [1.47.0]
entries with PR link; remove duplicate Linux blocks from [1.46.0] Fixed.
Append settings credit line for cucadmuh.

Frank Stellmacher bca45d5a80 feat(servers): scan actions + edit existing server profiles (#780)
* feat(server-scan): plumbing for triggering library scans

Adds `startScan` / `getScanStatus` against the Subsonic API
(`fullScan=true` is Navidrome's extension), a small per-server scan
store, and a global polling hook (2 s cadence) that emits a toast when
each scan finishes. Scans can run on any configured server, including
inactive ones, by reusing `apiForServer`.

UI surfaces follow in the next commit.

* feat(server-scan): expose Quick / Full Scan in switcher + settings cards

Adds a `ServerScanActions` component with two variants (compact for the
server-switcher dropdown, card for the Settings server cards) backed by
the scan store from the previous commit. Full Scan requires a second
click within 3 s to confirm, matching the playlist-delete pattern.
Status slot shows a spinner with running track count while scanning, a
green check when finished, and a red icon on error.

The switcher row is converted from a single button to a flex container
so per-server scan controls don't hijack the server-switch click.
i18n added across all 9 locales.

* fix(server-scan): reorder switcher row to check / name / scan actions

Moves the check / spinner slot from the right edge to the left so the
spinner pop-in on server switch doesn't sit next to the scan icons.
Removes the layout shift that briefly hovered the Quick scan button
when the row re-rendered.

* feat(servers): edit existing server profiles in Settings → Servers

* Pencil-button on each server card opens an inline edit form that
  replaces the card (prefilled name / URL / username / password).
* `AddServerForm` reused with an `editingServer` prop — title flips to
  "Edit Server", submit label to "Save", magic-string field hidden (the
  edit scope is manual fields; magic-string remains an add-time invite
  shortcut).
* Edit saves unconditionally — ping runs post-save as a status indicator
  (analog to the existing Test button) instead of gating the save. Lets
  users update a profile when the server is currently unreachable.
* Translations across all 9 locales (`editServer`, `editServerTitle`).

* fix(servers): submit Add/Edit Server form on Enter

Wrapped the form body in a real <form>, made the submit button
type="submit", marked Cancel as type="button" so Enter no longer
cancels. Add-Mode now also responds to Enter — same flow, consistent
across both modes.

* fix(servers): collapse card action buttons to icon-only on narrow screens

* Quick-Scan / Full-Scan / Test buttons in each server card hide their
  text label below 1100px viewport via the .server-card-btn-label class
  and a single media query in connection-indicator.css.
* Labels remain accessible via data-tooltip and aria-label so screen
  readers + hover both keep working in the collapsed state.
* No content reflow above the breakpoint — pure additive CSS.

* fix(servers): include Use button in icon-only narrow-screen collapse

The Use ("Verwenden") button on inactive server cards lacked the
.server-card-btn-label wrapper, so its text stayed visible at narrow
viewports and pushed Edit/Delete off-screen. Added a Power icon and
wrapped the label so it collapses alongside the other action buttons.

Frank Stellmacher 606a150e01 feat(settings): clock format setting (Auto / 24h / 12h) (#742)
* feat(settings): clock format setting (Auto / 24h / 12h)

Reported on the Psysonic Discord — the Queue side panel's ETA label
and the sleep-timer preview both render via `formatClockTime`, which
just calls `toLocaleTimeString` and so follows the user's system
locale. On en-US that means AM/PM, with no in-app way out.

Add a tri-state **Clock Format** setting under
**Settings → System → App Behavior**:

* `auto` (default) — keep the existing locale-driven behaviour, so
  bestehende installs are unaffected on first launch.
* `24h` — force 24-hour wall-clock output everywhere
  `formatClockTime` is used.
* `12h` — force AM/PM output.

Wired through `authStore` (`clockFormat`, `setClockFormat`), exposed
via `CustomSelect` in `SystemTab`, and threaded into the two
consumers (`QueueHeader`, `PlaybackDelayModal`) so they re-render on
change. `formatClockTime` itself stays a pure helper — it accepts the
setting as an optional second argument and maps it to `hour12`.

Locale coverage: all nine bundled locales (en, de, es, fr, nl, nb,
ru, zh, ro) get the four new settings strings. Pin tests added for
the `setClockFormat` setter and the `hour12` mapping in
`formatClockTime`.

Frank Stellmacher 2d27428056 feat(settings): player bar layout — per-control visibility toggles (#627) (#721)
Adds a new sub-section under Settings → Personalisation (Advanced) that
hides individual controls in the player bar: Star rating, Favorite
(heart), Last.fm love, Equalizer, Mini player. Last.fm love still only
renders when a Last.fm session exists; the overflow row in the player
collapses when both Equalizer and Mini player are hidden.

- New `playerBarLayoutStore` (Zustand + persist, items[{id, visible}] +
  rehydrate sanitize) following the queueToolbar / playlistLayout
  pattern; defaults to all visible.
- New `PlayerBarLayoutCustomizer` reuses the same row + toggle pattern
  as the other personalisation customisers.
- Gates threaded through `PlayerTrackInfo` (3 controls), `PlayerBar`
  (EQ + Mini buttons), and `PlayerOverflowMenu` (EQ + Mini in the
  overflow row, with row-level conditional).
- `PersonalisationTab`: added as the last advanced sub-section so it
  only appears when the global Advanced Mode toggle is on.
- Settings search index gets entries for both Playlist page layout and
  Player bar (playlist row was missing).
- New i18n keys `settings.playerBar*` in all 9 locales.

Reuses kveld9's design from PR #627; not merged because the locale
split and the Advanced Mode refactor landed afterwards. Credited via
Co-Authored-By trailer + a new line in settingsCredits.ts under the
existing kveld9 entry.

Frank Stellmacher 651a3f276a feat(settings): global Advanced Mode toggle + playlist page layout (#556) (#720)
Adds a per-element visibility toggle for the playlist detail page (Add
Songs, Import CSV, Download ZIP, Cache Offline, Suggestions) and reworks
the way uncommon options are surfaced: instead of a per-tab collapsible
group, a global "Advanced" toggle in the Settings header reveals all
`advanced` sub-sections across every tab and marks each one with a small
badge. Sets the pattern up so any future advanced option lives in its
natural tab, gated by the same switch.

- New `advancedSettingsEnabled` boolean on `authStore`
  (UiAppearance slice, persisted with the rest of the store).
- `SettingsSubSection` gains an `advanced?: boolean` prop. Hidden when
  the toggle is off; renders an "Advanced" pill in the header when on.
- Settings header gets a Toggle-Switch next to the search lupe.
- `PersonalisationTab` flattens — Sidebar + Home stay always visible;
  Artist sections, Queue Toolbar, and the new Playlist layout get
  `advanced` and disappear by default. `PersonalisationAdvancedGroup`
  component + CSS removed.
- New `playlistLayoutStore` (Zustand + persist, items[{id,visible}] +
  rehydrate sanitize) following the queueToolbarStore pattern.
- `PlaylistHero` and `PlaylistSuggestions` gate the four toolbar buttons
  and the suggestions rail on the store directly.
- One-time migration in MainApp on mount: if the user had opened the
  old per-tab Advanced group (`psysonic_personalisation_advanced_open
  === 'true'`) OR already customised any of the three sub-sections,
  Advanced Mode auto-enables on first launch. Idempotent via a
  localStorage flag; legacy key removed afterwards.
- New i18n keys `settings.advancedMode`, `settings.advancedModeTooltip`,
  `settings.advancedBadge`, `settings.playlistLayout*` in all 9 locales.

Reuses kveld9's design from PR #556; not merged because the locale split
landed afterwards. Credited under the existing kveld9 entry in
settingsCredits.ts.

Frank Stellmacher 2409a1fec8 refactor(i18n): split locale files into per-namespace modules (Phase K) (#688)
Each src/locales/<lang>.ts (~1800 LOC) becomes a folder src/locales/<lang>/
with one module per i18n namespace (44 each) plus an index.ts barrel that
reassembles <lang>Translation in the original key order.

Mechanical, script-driven split with a JSON round-trip check: every
locale object is byte-identical to its pre-split form. i18n.ts is
unchanged — './locales/<lang>' now resolves to the folder index.

The per-namespace settings.ts files land ~440-460 LOC; a single i18n
namespace is the natural, non-arbitrary split unit for a flat string
table, so they are intentionally left whole.
