fix(scanner): keep album tag order from the files instead of alphabetical (#5872)
Album-level tags were ordered by frequency and then alphabetically by value.
Album.Genre is just the first genre in that list, so any album whose genres tie
on frequency, which is the normal case, displayed the alphabetically first genre
rather than the first one in the file. A file tagged
"Native American New Age; Indigenous American Traditional Music; Ambient"
showed up as "Ambient".

Break frequency ties on order of appearance instead. This affects all
album-level tags, so mood tagged "Happy; Chill" now keeps that order too.
MediaFiles.ToAlbum already sorts the files by path before flattening their tags,
so the aggregated order stays deterministic across scans.

Only album genre was affected; media_file tags already preserved file order.

fix: add Navidrome UserAgent in all outgoing requests (#6020)
* There has been a report about navidrome hitting listenbrainz hard
and the listenbrainz guys wanting to be able to distinguish navidrome

* feat: apply Navidrome User-Agent to all outgoing HTTP requests

Add utils/httpclient, a shared http.Client factory whose transport sets
the User-Agent header (Navidrome/{version} - https://github.com/navidrome)
on any request that does not already have one, and use it at every place
the server builds an HTTP client: Last.fm, ListenBrainz and Deezer agents
and auth routers, insights collector, backgrounds handler, and the plugin
host HTTP service. Plugin-set User-Agent values are preserved. The
per-request header lines from the previous commit are superseded by the
transport.

82b9a44a1f fix(log): redact sensitive auth headers from request logs
The trace-level request log dumps all headers as a JSON blob, but the
redaction hook only had query-param patterns, so Authorization, X-Emby-Token,
X-MediaBrowser-Token and X-Nd-Authorization leaked their tokens in plaintext.
Add one pattern that blanks those header value arrays at the log sink.

feat: add optional natural sort order for names and titles (#6015)
* feat: add optional natural sort order for names and titles

Album, artist, song and playlist lists sort with a plain text comparison, so
names containing numbers come out as "Foo 1, Foo 10, Foo 2" instead of
"Foo 1, Foo 2, Foo 10" (issue #4554).

Adds an EnableNaturalSorting option, default off, that switches those sorts to
a NATSORT collation registered on every connection and backed by
natural.CompareFold. natural.Compare gained an ASCII case-folding variant
because it replaces 'collate nocase': sort_* columns hold raw tag values, so
without folding they would order uppercase before lowercase.

Applying the collation only inside mapSortOrder would have missed the default
configuration entirely, since that mapper runs only when PreferSortTags is on.
setSortMappings now also rewrites the order_* columns when natural sorting is
enabled on its own. Sorts over plain text columns that are not order_* columns
(playlist.name, album.name, media_file.title, playlist_tracks title) are
wrapped explicitly, and qualified with their table because 'user' is joined and
also has a 'name' column.

The option defaults to off because the collation cannot use the existing
indexes: measured on a synthetic 110k album library, the first page of an
album-by-name listing goes from 0.03ms to 14ms. Indexing the expression was
rejected outright - an index declared with a custom collation makes the whole
database unreadable to any tool that does not register it, including the
sqlite3 CLI, which fails even on 'select count(*)' and 'pragma integrity_check'.

* refactor: fold the two sort-order mappers into one

mapSortOrder and mapNaturalOrder shared the same regex and loop, differing only
in the expression they substituted, and setSortMappings picked between them with
a two-case switch. mapSortOrder now selects the column shape itself and defers to
collatedSort for the collation, so the 'collate' clause is emitted in one place
and the caller only has to decide whether any mapping is needed at all.

The mapper tests were three near-identical cases that each hard-coded one flag
combination; they are now a DescribeTable covering all four combinations of
PreferSortTags and EnableNaturalSorting, which the previous set did not. The
album sorting specs collapse the same way. Behavior is unchanged.

* fix: leave plain sort columns alone when natural sorting is off

collatedSort wrapped its column unconditionally, so the tiebreakers added for
plain text columns picked up 'collate nocase' even with EnableNaturalSorting
off. media_file.title, the playlist_tracks alias of it, and user.user_name are
all declared without a collation, so a default install would have silently
switched those tiebreaks from binary to case-insensitive ordering. Only
playlist.name was already NOCASE and genuinely unaffected.

The helper is now naturalSort and returns the column untouched unless the option
is on, so the default path keeps the collation each column was declared with.
sortCollation had a single remaining caller and folded into mapSortOrder.

Tests: the CompareFold table body was a verbatim copy of the Compare one, so
both now go through one expectOrder helper, and the album sorting specs inline
two single-use closures.

* fix(natural): defer the leading-zero tie-break to keep ordering transitive

Compare applied the padding difference between numerically equal digit runs only
when one side ended at the digit boundary, and ignored it mid-string. That made
the relation intransitive: CompareFold("1","1a") < 0 and CompareFold("1a","01a")
== 0, yet CompareFold("1","01a") > 0.

SQLite requires a collating function to be transitive and leaves ORDER BY
undefined otherwise, so registering this as NATSORT was not safe. Reproduced with
the real driver on three artist names that occur in practice - "3", "3 doors
down" and "03 greedo" - where paging one row at a time returned "03 greedo"
twice and dropped "3" entirely.

The padding difference is now carried as a tie-break that is applied only when
the strings are otherwise equal, which restores transitivity while keeping the
documented intent (a01 < a1, a0 < a00). Three existing entries changed: each
asserted that two distinct strings compare equal, which was the same defect seen
from the other side.

Found by the Codex review on #6015.

fix(plugins): read the loaded plugin from a local, not the shared map (#6014)
Plugins load concurrently through an errgroup. loadPluginWithConfig wrote
m.plugins under m.mu but read it back unlocked to pass to callPluginInit,
so one goroutine's write raced another's read. Caught by -race on master
(run 32608293134): all 640 specs passed, the job failed only on the race.

Capture the pointer while holding the lock and use the local. Holding m.mu
across callPluginInit would be wrong, since that runs arbitrary plugin code.

feat(jellyfin): non-expiring, audience-scoped tokens revocable by password change (#6013)
* feat(auth): add per-user token_epoch column and bump method

* feat(auth): add aud and ep claims, omitted when zero

* feat(auth): add CreateAPIToken for non-expiring, audience-scoped tokens

* feat(auth): add CheckClaims for epoch and audience validation

* feat(jellyfin): issue non-expiring, jellyfin-scoped access tokens

* fix(subsonic): reject API-scoped and revoked tokens on the jwt path

* fix(server): reject API-scoped and revoked tokens on the native API

* fix(server): pin the token-subject guard and stop leaking test config

Adds a regression spec for the DevAutoLogin/ExtAuth guard in
tokenAllowed, switches its comparison to case-insensitive to match
the user lookup's own COLLATE NOCASE semantics, and restores Subsonic
JWT test config after each spec instead of leaking SessionTimeout.

* feat(request): add a token epoch holder for handler-to-middleware signalling

* refactor(server): write the refreshed JWT header after the handler runs

* feat(auth): revoke all tokens for a user when their password changes

* fix(server): restore Unwrap on the JWT refresh writer so SSE write deadlines apply

* test(auth): pin that non-session tokens reject API access tokens

* test(jellyfin): pin token scoping and epoch revocation end to end

Exercises auth.CreateAPIToken and CheckClaims against the real Jellyfin
router and SQLite DB: the minted token has no exp and is aud-scoped to
jellyfin, and bumping token_epoch through the real UserRepository revokes
an already-issued token on the next protected request.

* test(nativeapi): pin the token-epoch handoff through a real password-change request

Drive a self password change through the real Authenticator/JWTRefresher
chain and a real SQLite-backed userRepository, so the epoch handoff between
Put and the refreshed-token writer is verified end to end, not as two
separately-tested halves. Also fix tokenAllowed to read the enriched ctx it
was given instead of r.Context(), so its warning log carries the username.

* refactor(server): drop tokenAllowed's now-unused request parameter

Finding-2 already moved every use to ctx; r was dead weight. Also note
in the new nativeapi test why it must stay the package's only real-DB
spec: db.Db() is a process-wide singleton its cleanup closes for good.

* refactor(auth): remove duplication in claim decoding and token minting

* refactor(auth): group aud with the standard JWT claims

* refactor(auth): read aud with the standard-claim accessor pattern

* fix(log): redact every api_key spelling the Jellyfin API accepts

* fix(auth): bind session tokens to the user id, not just the username

* fix(auth): return the token epoch from the same atomic increment

* fix(auth): bump the token epoch in the same statement as the password write

* chore(auth): trim comments to the why-only budget

feat(artwork): report what a config-fingerprint backfill enqueued (#6010)
* feat(artwork): report what a config-fingerprint backfill enqueued

A backfill re-resolves every entity, and on a large library that is tens of thousands of
external agent calls. It announced itself with a single line carrying nothing but an elapsed
time, so the size of the job was invisible until the request volume showed up hours later.

Log the item count, the per-kind breakdown, and a ceiling on the external lookups the queued
work can cost. The ceiling reuses ExternalLookupsPerItem, the same estimator behind the
`artwork reprocess` preview, so the two agree on what an item can cost.

backfill now returns a summary instead of a bare bool, which keeps the counts assertable
without capturing log output. Worker.Backfill keeps its (bool, error) signature, so its caller
is unchanged, and it reads the agent count off its own resolver.

* refactor(artwork): share the image-agent count and take it lazily

Counting image agents was written twice, once in the CLI for the `artwork reprocess` preview and
again as a resolver method for the backfill log. Two copies of "which agents count as image
agents" can drift, and the CLI estimate and the server log would then disagree silently.

Move the derivation next to the type it builds, as NewImageAgentCount, and call it from both.
The resolver method goes away with it: hanging the census on the resolver forced two nil guards
that its only caller could never trigger, because Worker always builds a resolver with agents.
The Worker keeps the *agents.Agents it is already handed instead of reaching through the
processor and resolver to find it.

Pass the count as a func. Building the agent list constructs every enabled agent (each one an
HTTP client and a cache goroutine) only to take its length, and a backfill returns early on an
unchanged fingerprint, which is what happens on nearly every restart.

* docs(artwork): say what the backfill lookup estimate does not bound

The comment called the number a ceiling, which the CLI comment on the same estimate already
contradicts: externalEstimate "claims no bound". Both are right about the local-source case and
only one of them mentions that a retried item asks its agents again.

perf(artwork): cap the stale-absent recheck at 100 items per kind per hour (#6007)
* feat(artwork): drip the stale-absent recheck instead of bursting it daily

Each hourly housekeeping tick now re-queues at most 100 absent states
per kind, oldest attempts first, instead of everything older than 24h
at once. External agents see a flat ~100 requests/hour per agent
instead of hourly bursts of ~2,000, and the effective recheck interval
self-scales with the size of the absent pool (~4 days at 10k absent
artists) while small libraries keep the 24h floor.

* feat(artwork): trust an absent artwork state for a week before rechecking

With the recheck now dripped at 100 items per kind per hour, the 24h
floor only governed small libraries, where the drip cap never binds;
they still re-asked every agent daily. A 7-day floor cuts that cost 7x
and, for large libraries, becomes the binding limit over the drip
cycle (~5.7k calls/day instead of ~9.6k at 10k absent artists).

Among comparable servers, this is still the second-most-eager recheck:
gonic retries misses every 30 days, Jellyfin and Funkwhale never do.

* refactor(artwork): state the drip's backpressure contract where it bites

Review follow-ups: the recheck limit deliberately caps the *selection*,
not the insertions — already-queued rows use up budget, so a stalled
drain admits no new work instead of building a recovery burst. Say so
in the interface doc, mirror it in the mock by truncating the sorted
candidates (matching the SQL's LIMIT-before-ON CONFLICT), and teach
`artwork status` and the worker doc the post-drip wording. Also pin
the one cmd fixture that still assumed a 24h recheck window.

feat(cli): add artwork cancel to call off queued artwork work (#6006)
* feat(cli): add `artwork cancel` to call off queued artwork work

A bulk backfill had no off switch. Changing an artwork setting bumps the config
fingerprint, which enqueues every entity in the library, and the only way to stop
it was to turn agents off -- which changes the fingerprint again and enqueues a
second full backfill. The escape hatch was the trap.

`artwork cancel` deletes pending queue rows selected by --kind and/or --priority,
with the --dry-run/confirm/-y flow `reprocess` already uses. Cancelling by
priority is the point: it drops a runaway backfill while leaving the bump-priority
rows an operator queued by hand.

It only touches the queue. Resolved artwork and the item_artwork state behind
`artwork explain` are left alone, and the trace of why a cancelled item last
failed goes with its row. Preserving that trace would mean writing it to
last_failure, which `explain` prints under "Gave up after" -- reporting a
cancellation as an exhausted retry budget. The help text says the trace is
discarded instead.

Two limits the help text states, because neither is guessable: work already
dequeued is not interrupted, and an item with no artwork state yet can be queued
again by the hourly missing-artwork recheck. Cancel calls off queued work; it
does not stop the worker.

--kind validates against RefreshableKinds, not the RecheckKinds `reprocess` uses:
the queue holds media file rows, so --all has to reach them. PurgeQueued follows
the repository's naming rule -- it finds its own rows and reports how many went --
and ignores retry_at, since a row still backing off is pending work. The preview
reuses CountByKindAndPriority rather than adding a counter. reprocessConfirm
became confirmUnlessYes(yes, in, verb) now that two commands prompt.

* refactor(cli): share the artwork queue filter between the preview and the delete

Follow-up cleanup on the previous commit; no change to what the command does,
apart from --all, noted below.

The "which rows does cancel touch" predicate was written three times: once as SQL
in PurgeQueued, once in Go in cmd's matchingQueueStats, and once more in the mock.
The preview and the delete could therefore drift, and the mock would keep the
tests green while they did. persistence now has one artworkQueueFilter, shared by
PurgeQueued and a new CountQueued, and cmd does no filtering at all.

That also makes the preview cheaper. It counted the whole queue and filtered in
Go, so `artwork cancel --kind al` scanned every row of every kind to print a
handful. CountQueued pushes the filter into SQL, which the drain index serves as a
range seek. CountByKindAndPriority is gone: it is CountQueued(nil, nil).

--all now selects with an empty filter instead of enumerating RefreshableKinds.
It is what the flag help already claimed, and the enumeration was narrower than
its own documentation -- a queue row whose item_kind this build does not know
survived `--all` with no flag combination able to remove it. It also restores
SQLite's truncate path: measured with EXPLAIN QUERY PLAN, a bare DELETE plans to
nothing, while `WHERE (1=1)` -- which an empty squirrel And renders -- plans to a
full index scan. A test pins the filter's emptiness so that cannot regress
silently.

Also folded together three copies of the parse-and-dedup loop (parseAll), two
copies of the queue-stats table (printQueueStats, now shared with `artwork
status`), two copies of the stat sum (queueTotal), and four copies of the
kind-to-prefix mapping (model.KindPrefixes). The PurgeQueued specs became one
DescribeTable that asserts count and delete agree on every selection.

* docs(cli): say when `artwork cancel` evaluates its selection

The help text covered the two limits that surprise an operator after the fact, but
not the one that bites during the prompt: the count is a preview, and the filters
run again on confirm. A scan or a manual refresh landing in between is cancelled
without ever appearing in the table the operator agreed to.

Deleting only the previewed rows was considered and rejected. The exposure is one
item re-resolving on next view instead of immediately: clearing an item's artwork
state is what every recovery path selects on, so a lost Bump row from
artwork.Refresh comes back at the same priority via provisional() on the next
request, and otherwise within the hour via EnqueueAllMissing. Buying a guarantee
against that costs the truncate path on --all, the flag that exists for a
29k-item backfill.

* refactor(cli): share one set of flag targets across the artwork subcommands

reprocess and cancel each declared their own kinds/all/dry-run/yes variables, but
cobra only ever parses the one subcommand being run, so the two sets could never
hold values at the same time. backup.go already binds one backupDir across two
subcommands and one force across two more; this follows that.

Ten package-level variables become six. Each command keeps its own help string
and its own valid-kind list, so --kind still reports RecheckKinds for reprocess
and RefreshableKinds for cancel, and --source and --priority stay registered only
on the command that has them.

The priority lookup table is now knownPriorities, freeing the artworkPriorities
name for the flag. The new name also reads better against priorityName's fallback
for a value it does not know.

feat(artwork): store the resolution trace so artwork explain works offline (#5980)
* feat(artwork): record the resolution trace so explain works without --live

The worker never attached a ChainTrace, so `artwork explain` had to re-walk the
priority chain at CLI time. That reconstruction could disagree with what actually
happened, and without --live it could not report the external tier at all.

The worker now traces every acquisition and stores it. `explain` reads the stored
trace by default and reports when it was recorded; --live re-walks and calls the
agents. Disc artwork keeps no row, so it always walks live.

A chain trace alone would have explained almost nothing about failures: six of the
seven ways an item can fail happen after the chain has already picked a winner. The
trace now covers those stages too, and has somewhere to live when they fail: the
retrying queue row carries the last failure, and the state row keeps it in
last_failure once the retry budget is spent and the queue row is deleted.

Measured on a copy of a 682MB / 43.6k-item library: +9.7MB (+1.4%). No row crosses
the WITHOUT ROWID overflow threshold, so list hydration is unchanged; only full
scans of item_artwork, which no request performs, read more pages.

* test(artwork): pin the give-up ordering that keeps a failure for unresolved items

recordGiveUp updates an existing row, and for a kind with a recheck path that row is
only created moments earlier by the absent settle. Recording before the settle would
lose the failure for every item that never resolved, with nothing to catch it.

* refactor(artwork): tighten the trace code after review

Four fixes worth taking:

The doc comments on ChainTrace and chainState.trace still said the worker never
attaches a trace and resolution stays allocation-free — the exact invariant this
branch reverses.

explain's report field meant both "the chain shown was walked just now" and "go out
for real", and was being passed to loadPluginAgents, which --live documents as the
only thing that may open external connections. Renamed to `walked` and restored
explainLive as the sole input to that decision.

A stored Detail is an error string on the failure paths, with no bound. The measured
"no row reaches the WITHOUT ROWID overflow limit" only holds while it is bounded, so
cap it at 200 runes.

offlineGate was a factory returning a constant closure; make it a plain gateFunc like
its sibling passthroughGate. Collapse five copies of the age-a-queue-row loop in the
worker tests into one helper.

* refactor(artwork): drop the offline explain walk, now that traces are stored

`artwork explain` reported the external tier without calling it, so a diagnostic
could not add load to a provider already rate-limiting us. Reading the stored trace
answers that better: it reports what the agents actually returned, not what would
be tried.

Nothing could reach the offline gate any more. It was installed only for a walk
with --live unset, which now happens for disc artwork alone, and disc rejects the
external candidate before any gate call. That made the gate, its sentinel error,
the would-try outcome and two of explain's verdicts unreachable.

Removes offlineGate, errOfflineSkipped, OutcomeWouldTry, the NewTracingResolver
live parameter and the CreateArtworkResolver argument threaded through wire.

Verified against a copy of a real library: disc artwork with "external" first in
DiscArtPriority and external services enabled still records the skip and issues no
agent call.

* fix(artwork): make explain's no-network guarantee structural, not incidental

Serving falls back disc -> album and track -> disc -> album. The resolver layer
explain uses has no such fallback today, so dropping the offline gate did not leak.
But the guarantee rested on which chains happen to lack an external tier, and the
serving layer already shows the fallback shape someone could mirror.

Without --live the tracing resolver is now built with no agents at all, so no chain
and no fallback added later can reach a provider. That is stronger than the gate it
replaces, which only intercepted the call.

The test pins it against exactly that regression: with the guard removed and the
serving fallback mirrored into resolveDisc, it fails.

* refactor(artwork): trim the trace plumbing

EncodeTrace was exported for nobody: only this package writes traces, and cmd reads
them. It becomes a ChainTrace method, which also drops the copy Steps made for a
caller that only wanted to serialize.

explain's report carried queuedSteps and failureSteps, both pure functions of the
queue and state rows already in the struct, which let a test set the two out of step
with each other. formatExplain derives them, as it already does for every other
display value.

The trace row format and its tabwriter empty-cell rule lived in two places, and the
"nothing was ever recorded" predicate in three.

* fix(artwork): clear the queue trace on a fresh re-enqueue

Enqueue's conflict clause reset attempts to 0 but left the new trace
column, so after a scan or refresh re-enqueued a previously-failed item
artwork explain showed "Attempts: 0" next to the prior lifecycle's
"Last attempt failed" trace. Clear trace in Enqueue (a fresh lifecycle
has no last attempt); EnqueuePreservingBackoff still keeps it.

* fix(artwork): treat a processing-stage error as indeterminate in explain

A read/hash/decode/store failure records an OutcomeError step and writes an
absent row, but explainResult only mapped external errors and unreadable
candidates to indeterminate, so the default verdict read "not resolved" —
presenting a processing failure as a definitive miss. The worker retries
these exactly as it retries an unreadable candidate, so classify any
OutcomeError as indeterminate too.

* fix(artwork): record a trace step when a chainless resolver faults

Playlist and radio resolvers walk no priority chain, so a fault (unreadable
upload/sidecar, or an m3u fetch error with no grid) returned localError/extError
without recording any trace step. The attempt then encoded [], leaving artwork
explain with an empty "Last attempt failed" and "Gave up after". Record a
fallback step in the faulted-no-image branch when nothing else did, and carry
the source label through resolveLocalFile so the step can name it.

* fix(artwork): trace the m3u failure at its source, not via the empty guard

A playlist's grid sampling records album-chain steps into the shared trace, so
the processor's empty-trace fallback no longer fires when the m3u remote image
fetch failed — the error that forced the retry was omitted from explain. Record
it where it happens, in resolvePlaylist's external step, as external:m3u.

* test(artwork): skip the chainless-fault spec on Windows

The spec provokes an open fault with a non-directory parent, but Windows maps
that to a not-exist error, so localError is never set and the item resolves
absent instead of failed. The sibling failed-on-unreadable-upload spec skips
Windows for the same class of reason.

* fix(artwork): don't label an absent empty-chain row as pre-tracing

explain reported "resolved before traces were recorded" for any stored row
with an empty chain, but an empty CoverArtPriority records a real, empty [] chain
and resolves absent. A recorded resolution that finds an image always records its
winning candidate, so only a row with a hash and no chain predates tracing; split
on the hash and report an absent empty chain plainly instead.

* fix(db): retimestamp the artwork trace migration after rebase

master merged a 2026-08-18 migration, so the original 2026-08-16 timestamp is now
older than the newest on the base branch and Goose would silently skip it on an
already-upgraded database. Bumped past it; the SQL is unchanged.

* fix(artwork): keep the m3u error detail in the trace

The m3u trace step recorded OutcomeError with no detail because resolveExternalStep
collapsed the gate's error to a bool, so explain showed only "external:m3u error -"
and could not tell a timeout from an HTTP error or an open breaker. Return the error
(normalizing not-found to nil so it stays a definitive miss, not a failure) and store
its message as the step detail; encodeSteps already bounds it.

* docs(artwork): note the give-up write relies on serial draining

recordGiveUp writes last_failure unconditionally; that is only correct because
the drain resolves each item serially, so no concurrent success can store artwork
between the write and the queue delete. Record the invariant at the call site.

docs(plugins): document how a metadata agent signals "not found" (#6001)
A MetadataAgent plugin reports "I have no data for this item" by returning an empty response
with a nil error. Any error it returns instead is treated as a plugin fault and retried with
backoff. That rule was not documented anywhere, so an author naturally returns an error for a
missing item, and Navidrome then retries every item the plugin's source does not cover.

This is not hypothetical: the artist-nfo-metadata plugin returned an error for every artist
without an artist.nfo, which kept those artists in the artwork retry queue for hours and
tripped the artwork circuit breaker for the plugin as a whole.

Document the rule on the capability interface, which ndpgen copies into the Go PDK, and in the
MetadataAgent section of the plugin README.

ci: pull base images through mirror.gcr.io instead of ECR Public (#5997)
CI builds were failing at random with:

    buildx failed with: toomanyrequests: Rate exceeded

The 429 comes from public.ecr.aws, not Docker Hub. AWS caps unauthenticated
ECR Public pulls at 1 per second per source IP (authenticated: 10/s). The
build matrix starts 11 jobs at once and each resolves 4 base images, so
roughly 44 anonymous pulls land in a couple of seconds — from GitHub runner
IPs that are shared with every other GitHub customer.

Measured against public.ecr.aws with an anonymous token, 60 requests at
concurrency 30 returned 31x 429 in 0.48s.

The same probe against mirror.gcr.io (Google's Docker Hub pull-through
cache) returned zero errors: 750 manifest requests up to ~141 req/s, plus
120 layer blob requests at concurrency 60. Google publishes no rate limit
for it, so this is measured headroom, not a contract — but it is roughly
10x the pipeline's peak rate, and cached pulls do not count against Docker
Hub's limits either.

Authenticating to ECR Public was the alternative. It was rejected because
10 pulls/s is still under the ~44-pull burst, it needs an AWS account plus
a secret, and secrets never reach fork pull requests — so forks would keep
failing. The mirror fixes forks too.

Verified buildkit honours the mirror block by routing a build through a
local logging registry: all 6 requests (manifests and blobs) hit the mirror,
none went to Docker Hub directly. Confirmed mirror.gcr.io answers 200 for
buildkit's "?ns=docker.io" query form on all four images, for both GET and
HEAD. Confirmed buildkit falls back to Docker Hub when the mirror is
unreachable — the build still succeeds, but the resolve takes ~30s instead
of ~0.3s, so a mirror outage means slow builds, not broken ones. The
existing Docker Hub login covers that fallback on main-repo runs.

fix(cli): write pls -p playlist output to stdout (#5996)
The export path used the `println` builtin, which writes to stderr, so
`navidrome pls -p X > playlist.m3u8` produced an empty file while the M3U
body was interleaved with the startup logs on stderr.

`println` also appended a newline that `ToM3U8` already provides, so the
piped output had a stray trailing blank line that `-o file` did not. Both
destinations are now byte-identical.

The stdout/file choice moved into a `writePlaylist` helper shared by
`pls -p` and `pls export -p`, which both had the same bug. It takes the
destination as an `io.Writer`, matching the existing convention in
cmd/artwork.go.

ci: lint with the golangci-lint version the Makefile declares (#5994)
* ci: lint with the golangci-lint version the Makefile declares

The workflow asked for `version: latest` while the Makefile pins
`GOLANGCI_LINT_VERSION ?= v2.12.0`, so `make lint` and CI ran different
linters. golangci-lint v2.13.0 started reporting G404 on three existing
`rand.Shuffle` calls, which turned every PR red without a line of Go
changing.

Read the version from the Makefile instead of resolving `latest`, so the
two stay in step and a new release cannot break unchanged code.

feat(cli): let artwork explain/refresh accept an id without its kind (#5988)
* feat(cmd): make artwork explain/refresh accept an id without its kind

The kind can now come from the id itself: a full artwork id (al-<id>)
carries it in the prefix, and a bare id is resolved across tables via
GetEntityByID. The explicit <kind> <id> leader still works.

* fix(cmd): keep refreshing resolvable ids when others fail to resolve

resolveArtworkTargets now collects a self-describing id it cannot resolve
as a failure instead of aborting, so refresh reports and skips the bad ones
and still queues the rest, matching refreshItems per-item behavior. explain
stays strict and rejects any unresolved input.

perf(artwork): compute the blurhash DCT separably (#5989)
The cosine basis factors into cosX[i][x] * cosY[j][y], so the pixel loop
does not need to visit every (i,j) pair. Each row now collapses to xComp
dot products, folded over yComp once per row: w*h*xComp + h*xComp*yComp
multiply-accumulates instead of w*h*xComp*yComp.

Encoding is ~60% faster at every input size, and ~80% faster at the 128px
size the artwork pipeline actually feeds it (263us -> 53us). Hashes are
byte-identical, so the existing golden-value specs cover the rewrite.

count, size and modtime held constant, so dropping the filename from the hash
fails. Both mutations were verified to fail before this change and pass after.

fix(playlist): block track edits on synced playlists across all APIs (#5984)
* fix(playlist): block track edits on synced playlists across all APIs

A synced playlist's tracks come from its source file, so any track edit made
through the UI or an API was silently reverted on the next scan. Track mutations
funnel through two service guards, checkTracksEditable (incremental edits) and
Create (wholesale replace, used by Subsonic createPlaylist and Jellyfin's
replace path), which each duplicated the smart-playlist check. Both now consult
a shared model.Playlist.TracksEditable() predicate, so the native, Subsonic, and
Jellyfin paths are all locked: track edits return ErrNotAuthorized (403, or
Subsonic error 50) instead of being accepted and lost. Metadata-only edits
(name, comment, public, the sync flag itself) still go through checkWritable and
are unaffected. In the UI, a synced playlist's track list becomes read-only,
mirroring how smart playlists already behave.

* fix(playlist): return 409 Conflict for non-editable playlist track edits

The previous commit rejected track edits on smart and synced playlists with
ErrNotAuthorized (403). That conflates two different things: a 403 says the
caller lacks permission, but a synced or smart playlist's tracks are immutable
for everyone, including the owner and admins. It is a property of the resource,
not the caller.

Introduce ErrPlaylistNotEditable and return it from both track-edit guards. The
Native and Jellyfin APIs now map it to 409 Conflict; Subsonic maps it to error
50, the closest code it has (it has no read-only concept). The Native track
handlers previously mapped this rejection inconsistently (400 on add, 500 on
remove, 403 on reorder) through a new shared writePlaylistError helper. Genuine
authorization failures (non-owner, non-admin) still return ErrNotAuthorized.

* fix(playlist): surface synced read-only state in picker, Jellyfin, and OpenSubsonic

Follow-up to the track-edit lock: the read-only state was enforced but not
advertised consistently, so clients still offered edits that the server rejects.

- UI: the Add to Playlist picker filtered targets by isWritable only, offering
  synced playlists that then 409 on add. It now filters with canChangeTracks.
- Jellyfin: addToPlaylist/removeFromPlaylist hard-coded every error to 404, so a
  locked playlist reported "not found" instead of 409. They now return 409 for
  ErrPlaylistNotEditable while keeping the deliberate anti-probing 404 for every
  other error (a non-owner never reaches ErrPlaylistNotEditable, so 409 leaks
  nothing).
- OpenSubsonic: buildOSPlaylist marked only smart playlists readonly; owned
  synced playlists advertised readonly=false. Readonly now also covers
  !TracksEditable(), matching the existing smart-playlist treatment.

* fix(jellyfin): report CanEdit from playlist editability in permission probes

getPlaylistUsers and getPlaylistUser returned CanEdit: true unconditionally, so
Finamp (which probes this before showing edit controls) offered track editing on
synced/smart playlists whose add/remove requests now return 409. Both handlers
now fetch the playlist and set CanEdit from TracksEditable(), keeping the
deliberate non-owner looseness (CanEdit stays true for a normal playlist a
non-owner views) and mapping any lookup error to 404 like the sibling probes.

* fix(playlist): check ownership before editability when replacing tracks

Create checked TracksEditable() before ownership, so a non-owner replacing
another user's public smart/synced playlist (Jellyfin updatePlaylist with a
non-empty Ids list) received a 409 read-only conflict instead of a 403
authorization failure. The incremental guards check ownership first via
checkWritable; Create now matches that order. Subsonic is unaffected (both errors
map to code 50). Owners of their own smart/synced playlists still get the
read-only conflict.

* fix(jellyfin): return 403 for locked playlists, matching Jellyfin

Jellyfin itself refuses edits on its file-backed playlists with Forbid() (403):
PlaylistsController gates every mutation on OwnerUserId == caller or a share with
CanEdit, and playlists imported from .m3u files satisfy neither. Its CanEdit is
an ACL field, not a read-only marker, and Jellyfin core has no server-managed
playlist type at all.

Our Jellyfin routes exist to imitate that API, so ErrPlaylistNotEditable now maps
to 403 there instead of 409. The native API keeps 409 (a resource-state conflict
is the accurate REST answer where we define the contract) and Subsonic keeps
error 50, its closest code.

* chore(playlist): trim comments added by this branch

Several comments ran to three or four lines and carried rationale that belongs in
the commit history rather than the code: what Jellyfin does with its own
file-backed playlists, and restatements of the expressions directly below them.
Each block is now one or two lines covering only the non-obvious why.

fix(jellyfin): honor the Filters, SortBy and MaxHeight params clients actually send (#5981)
* fix(jellyfin): honor Filters=IsFavorite on /Artists and /Artists/AlbumArtists

listArtistsByRole hand-built its itemsQuery and never set favOnly, so the
favorites filter was silently dropped on both artist routes while /Items
honored it. Finamp's home screen asks for favorite artists once per load and
was served the entire artist list instead: 10,298 artists, 6.15 MB, 2.7s on
a real library, and the wrong data on screen.

Extract the favOnly parsing that parseItemsQuery already did into
parseFavOnly and use it in both places. listArtists now adds the starred
predicate to notMissing rather than replacing it, matching listAlbums and
listSongs, so a favorite artist whose files are gone stays excluded.

* fix(jellyfin): map SortBy=Runtime to duration for albums and songs

sortColumnsByType had no runtime/runtimeticks key for any type, so Finamp's
"Duration" sort silently misbehaved in two different ways.

Albums: Finamp sends a bare SortBy=Runtime. Nothing matched, opts.Sort stayed
empty, and applyOptions skips OrderBy entirely when Sort is empty — so the
query ran with no ORDER BY at all and Ascending and Descending returned
identical lists.

Songs: Finamp sends SortBy=Runtime,AlbumArtist,Album,SortName. applySort takes
the first *recognized* key, so Runtime was skipped and the list came back
sorted by album artist while looking correct.

Both repos already accept a duration sort (mediafile_repository maps it
explicitly; album_repository falls through to the column name), so no
migration is needed. Sorting 97k songs by duration costs a temp B-tree
(~114ms on a prod-sized copy) — the same cost the Subsonic and UI duration
sorts already pay, and correct where the previous behaviour was merely fast.

* fix(jellyfin): apply the played/unplayed filters and MaxHeight image bound

Filters was matched with a substring test for IsFavorite, so every other token
Jellyfin defines was silently dropped and the response kept rows it should
have excluded. Finamp sends Filters=IsUnplayed in normal use.

Replace the bool with a parsed itemFilters carrying nullable favorite and
played flags, so isFavorite=false and isPlayed=false are real filters rather
than indistinguishable from an absent param. Standalone params are read first
and the Filters list overrides them, the precedence real Jellyfin has.
IsFavoriteOrLikes now maps to favorites deliberately instead of by substring
accident; Likes, Dislikes, IsFolder, IsNotFolder and IsResumable have no
Navidrome equivalent and are dropped rather than half-applied. The negative
cases match NULL as well, since annotations are LEFT JOINed and an untouched
item has no row.

getItemImage read only maxwidth, so a client sending just MaxHeight got the
full-size original: measured against a real cover, maxHeight=100 returned
82,570 bytes where maxWidth=100 returned 3,316. Use the tighter of the two
bounds.

* refactor(jellyfin): share the plain-param parser between /Items and /Artists

listArtistsByRole hand-listed the itemsQuery fields it happened to need, which
is exactly how the favorites filter went missing: the literal has been amended
in four of the five commits that touched it. Extract listParams for the fields
that come straight from query params so both paths read one parser, and the
next supported param reaches every list path instead of only /Items.

Also from the cleanup pass: collapse imageSize to a single clamped comparison
and read its bounds through req.Params like the rest of the package, which
drops the strconv import; build the artist and playlist filter lists with the
flat append shape the album and song paths already use, instead of re-wrapping
opts.Filters into a nested And per predicate; drop a nil guard in
listPlaylists that no caller can reach, since both paths into queryItemsOfType
build QueryOptions without Filters.

applySort now logs when no SortBy key resolves at all — a miss inside a
fallback list is normal, but none matching means a silently ignored sort, the
failure mode that hid the Runtime bug. Its doc comment records why the
remaining keys cannot simply be joined.

Folds three duplicated test bodies into the tables that already parameterize
them, and covers the artist-parent album branch, which reaches notMissing
through filter.AlbumsByArtistID rather than the default branch.

* docs(jellyfin): correct how applySort describes Jellyfin's SortBy semantics

The comment claimed SortBy is a comma-separated fallback list. It is not:
RequestHelpers.GetOrderBy (10.10) builds one (ItemSortBy, SortOrder) pair per
key, so Jellyfin orders by every key in turn. Navidrome applies only the first
recognized one, which is a real divergence — secondary keys never break ties —
not the intended reading of the parameter.

The assertion that the keys cannot be joined was also wrong. buildSortOrder
does split its input on commas; what it maps is the whole string, so joining
raw Jellyfin key names misses the mappings. Mapping each key first and joining
the results would work, which makes multi-key sorting a real option rather
than a blocked one. Documenting the current behaviour as a known divergence
until then.

* fix(jellyfin): order by every recognized SortBy key, not just the first

Jellyfin orders by each SortBy key in turn, so "DatePlayed,SortName" means
break ties by name. Navidrome applied only the first recognized key and dropped
the rest, which is 28% of the sort traffic on a real server (23 of 82 requests
in 12h carry 2-5 keys). Most were harmless because the primary key dominates,
but PremiereDate,Album,ParentIndexNumber,IndexNumber,SortName came back
unordered within a year.

The keys cannot simply be joined: sortMapping keyed on the whole Sort string,
so a joined value missed every mapping and fell through to raw column names.
Make it resolve a comma list per part, but only when every part is a known key
— the four existing callers that pass raw column lists (core/matcher,
core/lyrics, core/maintenance, subsonic/browsing) all carry a part that is not
a mapping key, several with their own direction, so they keep falling through
exactly as before. Verified each one.

applySort now collects every recognized key, skipping duplicates so
ParentIndexNumber,IndexNumber does not repeat a column. random stays alone: the
repo matches it by exact string equality, so joining it would both break that
path and emit a bare 'random' column into the ORDER BY.

Verified against a prod-sized copy: every multi-key combination seen in real
traffic returns 200, and a secondary key now changes the order within a tied
year for songs. Albums are unchanged there, because their max_year mapping
already ended in ", name".

* fix(persistence): resolve sort mappings exactly once

Making sortMapping resolve a comma list per part broke an invariant it had
been relying on: idempotence. sanitizeSort mapped the sort key up front and
applyOptions then ran buildSortOrder over the result, so sortMapping was
already being handed its own output. That was harmless only while a mapped
value could never look like a key list.

media_file's rated_at maps to "rating, rated_at", and both parts are keys, so
the second pass expanded it to "rating, rating, rated_at". Found by
round-tripping every mapping in all four repositories; it was the only
collision, and the duplicate sort key was benign in SQL, but any future mapping
of that shape would silently change meaning.

sanitizeSort now validates without resolving, leaving buildSortOrder as the
single mapping point. The generated SQL is unchanged — the whole suite passes
apart from the two specs that asserted the old return value, which are updated
and joined by a round-trip guard covering exactly the rated_at shape.

Also use the paren-aware splitFunc that buildSortOrder already uses, so an
expression carrying commas inside its parentheses cannot be split apart.

* refactor(jellyfin,persistence): flatten the sort resolution paths

Cleanup pass over the branch, no behavior change.

sortMapping loses the len(parts)>1 guard, which existed only to pick between
two identical toSnakeCase exits; the single-key case now falls through the same
loop. lookupSortMapping hands back the snake_case form it had to derive so the
fallback stops recomputing it — toSnakeCase is two regexps, and on a miss it was
running twice per call. sanitizeSort now asks lookupSortMapping instead of
probing the map itself, so "is this a known sort key" has one answer; the two
had already drifted, since sanitizeSort tried one casing where the resolver
tries three.

applySort folds the nested random branch into the skip condition and the two
trailing length tests into one switch. setSortMappings documents the invariant
the comma-list rule depends on, where someone adding a mapping will read it.

The README line describing SortBy still said only the first key applied, which
the commit before last made false.

Tests: the twelve near-identical sorting specs become one DescribeTable of
(itemType, SortBy, want) triples, 124 lines to 36, and the applyOptions
round-trip assertion collapses to the buildSortOrder call its sibling uses.

* fix(jellyfin): keep annotation filters out of search, resolve sorts per part

Two findings from the Codex review on #5981.

The played/unplayed filters turned working requests into 500s when combined
with SearchTerm. Search runs a two-phase FTS query whose first phase selects
rowids with no annotation join, so a starred or play_count predicate there is
"no such column", not a filter. Measured against master: MusicAlbum with
SearchTerm and Filters=IsUnplayed went 200 -> 500, likewise IsPlayed and the
Audio equivalents. listAlbums and listSongs now skip those predicates on the
search path, matching what listArtists already did. That also clears the same
500 master already had for Filters=IsFavorite with SearchTerm.

sortMapping resolved a comma list only while every part was a known key, so a
list mixing a plain column with a mapped key kept neither: MusicAlbum
SortBy=Runtime,SortName arrives as "duration, name", and duration is a plain
album column, so name stayed raw instead of expanding to order_album_name.
Albums whose name differs from its sort form — 1,366 of 6,987 on a real
library — then ordered by the wrong secondary key, and PreferSortTags was
ignored. Each part is now resolved on its own, which is what setSortMappings
already documents for a single field. Verified every in-tree caller that passes
a raw column list still produces its original ORDER BY.

Codex also asked for the artist search path to apply the same filters. It
would 500 for the reason above, and wrapping the library scope in a compound
filter makes requestedLibraryIDs stop recognizing it, silently widening the
search past the requested ParentId.

* fix(jellyfin): honor the first SortOrder value for a multi-key sort

applySort compared the whole SortOrder string with "Descending", so a per-key
list like SortOrder=Descending,Ascending failed the match and every key,
including the primary, sorted ascending — the exact opposite of the request.
Take the first comma-separated value, which Jellyfin also uses for any key past
the end of the SortOrder list. True per-key directions can't be expressed
through the single opts.Sort string and are left out; no observed client sends
a SortOrder list.

* fix(playlist): preserve smart playlist counters on re-import (#5907)

* perf(playlist): skip re-importing unchanged NSP files (#5907)

* feat(playlist): also store content hash for M3U imports (unused for now)

* fix(playlist): return stored record when skipping unchanged NSP import

Skipping before copying the stored identity broke the ImportFile(sync=false)
contract: callers received an ID-less playlist and the requested Sync change
was silently dropped.

* refactor(playlist): hash imports once at the caller; protect smart counters in Put

Move content hashing out of both parsers into the code that owns the file
(parsePlaylist and ImportFile), removing the NSP double-buffer and the
duplicated hashing idiom. Put now drops song_count/duration/size for smart
playlists (PostMapArgs), disarming the counter-zeroing trap for all callers.

* fix(playlist): invalidate imported hash when rules are edited via API

Without this, a rules edit through the REST API kept the stored file hash,
so every scan skipped the unchanged file and never restored the file-backed
rules while sync was on.

* test(playlist): verify smart counters survive a re-import, end to end

The existing Put test seeds the stored counters with a raw SQL update, so it
pins the guard in PostMapArgs but not the pipeline around it. This test drives
the counters through a real evaluation instead: it saves a smart playlist, reads
it with GetWithTracks to populate song_count/duration/size, then saves the
playlist the way the scanner rebuilds it after parsing the .nsp file, with the
counters back at zero. Both routes fail without the guard, and the new one
covers the exact sequence reported in #5907.

Test taken from #5970, which diagnosed the same root cause independently.

Co-authored-by: Junker der Provinz <133605895+junkerderprovinz@users.noreply.github.com>

* test(playlist): build the service with artwork.NewUploader

The artwork pipeline in #5847 replaced core.NewImageUploadService() with
artwork.NewUploader(ds) and updated every call site it could see. The five call
sites this branch adds were written against the old constructor, so the merge
applied cleanly but left the package uncompilable.

* fix(db): re-stamp the imported_hash migration after the master merge

Master gained three migrations while this branch was open, the newest being
20260816180040. The original 20260808200333 stamp now sorts before them, so any
database already upgraded past that point would skip this migration entirely and
never get the imported_hash column. Same SQL, current timestamp.

* refactor(playlist): hash imported playlists with xxh3 and the id encoding

ImportedHash is a change detector, not a security boundary, so it does not need
a cryptographic digest. xxh3 is already a direct dependency and is used the same
way to fingerprint files in the artwork image store. Encoding the 128-bit digest
with id.Encode stores it in the same 22-char base62 form as every other id in the
schema, down from 64 hex chars.

No migration is needed: the imported_hash column has not shipped in a release, so
no database holds a value in the old format.

* refactor(playlist): extract the imported-playlist fingerprint helper

Both import paths encoded the hash inline, so how a playlist file is fingerprinted
lived in two places. A third import path that encoded it differently would silently
never match the stored value, turning the unchanged-file skip into a no-op.

feat(ui): show translation completion percentage in the language selector (#5979)
The language selector now shows how complete each translation is, so users
can see at a glance which languages are lagging behind English. The native
API's translation resource gained a termCount field holding the number of
non-empty terms in each language file; the UI divides that by the term count
of the bundled English file to get the percentage.

The percentage is wrapped in a Unicode left-to-right isolate, otherwise it
renders as "(%61)" beside right-to-left names such as Arabic and Persian.
Sorting runs on the plain language name, before the percentage is appended.

This also fixes prepareLanguage() mutating the bundled English translations:
for the English locale it received the shared en object and aliased albumSong
and playlistTrack onto it, growing en by 94 keys at runtime. That inflated the
denominator and made every language read about 14 points low. The aliases now
go on the merged copy instead.

fix(playlists): chunk track deletes to stay under the SQLite variable limit (#5977)
PlaylistTrackRepository.Delete built a single IN clause with one bind variable per
track, so removing more tracks than SQLITE_MAX_VARIABLE_NUMBER (32766) failed with
"too many SQL variables". Clients that sync a large playlist by adding the desired
tracks and then removing the stale ones would get the add committed and the removal
rejected, leaving the playlist with both sets of tracks and growing it on every sync.

Delete now works in chunks of 200, the same size addTracks already uses, and renumbers
once after the last chunk. Both callers already run inside a transaction, so the
delete stays atomic.

fix(artwork): re-resolve artwork when image files change on disk (#5965)
* fix(artwork): re-resolve artwork when image files change on disk

An image-only folder change (replaced, added, or deleted cover/artist
images, with no audio files touched) was detected by the scanner but never
reached the artwork queue, so clients kept seeing the old coverArt hash
until something else forced a re-resolution.

Phase 1 now diffs each changed folder's image list and imagesUpdatedAt
against the previously persisted folder row, and at the end of the phase
bulk-enqueues re-resolution for the affected entities: albums with tracks
in the folder or its direct children (covering disc subfolder layouts),
and, when an artist-pattern image is involved, artists with albums under
the folder's subtree, mirroring the artist resolver's upward search. The
artist mapping mirrors the resolver's sole-album-artist album selection.

New repository helpers keep the mapping set-based and light: folder
GetAllIDs, media_file GetAlbumIDsByFolder (distinct, indexed by
folder_id), and album GetSoleAlbumArtistIDs.

* refactor: simplify the image-change artwork enqueue after review

Load the previous folder image state through the existing GetFolderUpdateInfo
bulk pre-pass instead of a per-folder SELECT inside the persist transaction,
and skip the diff for new folders, whose artwork the scanner already enqueues
inline. Move the artist-image classification into core/artwork
(IsArtistImageFile) so the scanner shares the resolver's ArtistArtPriority
token grammar instead of re-parsing it (the copy mistreated image-folder as a
filename glob). Move the folder-subtree query into the folder repository
(GetSubtreeIDs) with LIKE escaping and expression-tree batching, share the
sole-album-artist predicate between the resolver and the album repository
(model.SoleAlbumArtistFilter), extract a chunked single-column query helper,
and deduplicate the ArtworkQueueItem literals behind scanArtworkItem.

* fix(persistence): keep slash-form paths in GetSubtreeIDs subtree predicates

The scanner hands GetSubtreeIDs io/fs slash-form paths, but filepath.Clean
rewrites them with backslashes on Windows while folder.path is stored with
forward slashes, so the descendant predicates matched nothing and nested
artist folders were never re-enqueued there. Normalize with path.Clean, like
HasAudioOutsideFolders does, and cover a nested path in the repo test.

* refactor(persistence): move the sole-album-artist rule into the album repository

SQLizer filters belong in the persistence package, not model. The rule
becomes an unexported filter shared by GetSoleAlbumArtistIDs and a new
GetBySoleAlbumArtist repository method, which the artist artwork resolver now
calls instead of building the squirrel filter itself.

* perf(scanner): resolve image-change artists in one query over album.folder_ids

The artist half of the image-change enqueue walked folder subtree IDs, then
media_file rows, then album rows, marshalling thousands of bound IDs through
the driver on each hop. Matching albums by their own folder_ids instead is one
statement, and folder_ids is the same source the artist resolver uses to
compute an artist's folders.

Benchmarked against a copy of the production DB (97k tracks, 10k folders,
7k albums): 87ms +/-196% -> 17.4ms +/-8%, 7.1MB -> 172KB, 103k -> 1.5k allocs.
The subtree predicate becomes a shared folderSubtreeFilter, so Folder
GetSubtreeIDs and Album GetSoleAlbumArtistIDs are no longer needed.

* fix(scanner): persist ancestor folders discovered by a quick scan

A quick scan skipped any new folder with no files of its own, so an artist
folder holding only album subfolders never got a row. Adding artist.jpg to it
later then produced no artwork enqueue: the entry was new, so the image diff
was skipped, and it has no tracks, so nothing was enqueued inline either.

Skip only genuinely empty new folders, matching what a full scan already
persists. This also fixes artist artwork resolving as absent for artists first
imported by a quick scan, since the resolver's folder climb needs that row.

Also normalizes the selective-scan preload paths with path.Clean, so its
descendant predicates match the stored slash-form paths on Windows.

* fix(persistence): chunk subtree paths and match artist globs by basename

Two regressions from earlier commits on this branch.

Collapsing the subtree query into a single statement dropped the chunking the
old GetSubtreeIDs had: each path expands into 3 OR terms and SQLite rejects an
expression tree deeper than 1000, measured at 166 paths. A library with more
artist-image folders than that (the prod copy has 158) would fail the whole
collect, dropping the album items with it, so the scanner now keeps them when
the artist query fails.

The artist-image classifier compared whole tokens after stripping album/, so a
directory-bearing glob like images/artist.* never matched the basenames the
scanner has. Match on path.Base, which is what album/artist.* already reduced
to; the resolver climbs parent folders, so an exact prefix is not knowable
here and a conservative match is the right failure direction.

* refactor(persistence): halve the repository surface this PR adds

Research on the four new repository methods found two were avoidable.

GetAlbumIDsByFolder now expands the changed folders to their direct children
in its own subquery, so Folder.GetAllIDs has no callers and is deleted, one
round trip per scan disappears, and the previously unchunked id/parent_id IN
lists are covered by the existing chunking.

GetBySoleAlbumArtist becomes an exported SoleAlbumArtistFilter, matching the
ParticipantIDFilter precedent for sharing a Sqlizer with core/, so the rule
still lives in persistence but AlbumRepository gains nothing and the mock shim
that ignored the artist filter is gone.

Also drops queryAllSliceChunked, now callerless, in favour of the file-local
slices.Chunk convention used by the sibling folder queries.

Rejected on measurement: matching the album path by album.folder_ids is exactly
equivalent (13975 pairs, zero difference) but has no index, so it scans every
album and runs 5-200x slower than the media_file route.

* refactor(persistence): stop reading the deprecated album_artist_id column

Both artist lookups this PR touches now go through participation, matching
the precedent in core/archiver.go and share_repository.go.

SoleAlbumArtistFilter uses ParticipantIDFilter, which is also faster: the
album_artists unique constraint is a covering index for it, while the old
column needed album_artist_album_id plus a row fetch.

GetSoleAlbumArtistIDsInSubtrees reads the sole artist out of the participants
JSON it already parses for the sole-artist check, rather than joining back to
album_artists, which measured ~1.6x slower on a prod-sized copy.

Verified equivalent on that copy: 6828 sole-artist albums and 1088 subtree
artists resolve identically via the column, the join and the JSON. The tests
now set a deliberately wrong album_artist_id so they fail if either query
starts reading it again.

* docs: trim comments that carry rationale belonging in commit messages

Five comments had grown past the budget with benchmark numbers, rejected
alternatives, and a duplicate of the constant's own explanation.

* refactor(scanner): move the image-change enqueue into phase_1_folders

The three functions were methods on phaseFolders, so they belong with the
type; phase_1_image_changes.go also read like a fifth phase, which it wasn't.

* refactor(scanner): extract the image-change collector into its own type

phaseFolders no longer owns the per-library map and the mapping methods; it
records into a collector and asks it to enqueue once. The collector keeps the
library alongside the folders, so enqueue needs only ctx and the datastore.

* refactor(scanner): simplify enqueue method by removing redundant datastore parameter

Signed-off-by: Deluan <deluan@navidrome.org>

* docs(scanner): drop the stale zero-value claim on imageChangeCollector

The collector now takes its datastore at construction, so the zero value is
no longer usable.

* fix(scanner): pin the persist stage to concurrency 1 and guard the collector

The stage relied on go-pipeline defaulting to one worker; stating it at the
stage makes the constraint visible where someone would change it. The
collector takes a mutex too, so the type is safe on its own terms rather than
by configuration.

feat(lyrics): support [bg:] tag and skip unknown tags in LRC files (#5966)
Unknown [name:value] tag lines (e.g. [al:], [by:]) were being glued onto the previous lyric line, producing junk cues like "\n[bg: " and stretching the line's timing. Now any unrecognized tag line is skipped whole, and the non-standard [bg:] background-vocal tag is parsed into cues attached to the preceding line under a bg agent, using the same agents representation the TTML parser emits for Apple-style background vocals.

feat(scrobbler): add per-user scrobble filter (#5964)
* feat(scrobbler): add scrobble_filter column to user

* feat(scrobbler): validate scrobble filter criteria on user save

* refactor(persistence): make smart playlist join helpers package-level

* feat(scrobbler): add MediaFileRepository.MatchesCriteria

* feat(scrobbler): filter external scrobbles with per-user criteria

* feat(ui): add scrobble filter field to user form

* fix(scrobbler): default scrobble_filter to empty string for existing users

* refactor(scrobbler): also gate playback reports on the scrobble filter

Playback reports carry the same track metadata to plugin scrobblers, so a
filtered track leaked through that third dispatch path. Skip the filter
evaluation entirely when no scrobbler is active.

* refactor(persistence): move criteria join building into criteria_sql.go

The join set a criteria needs was decided in criteria_sql.go but built in
smart_playlist_repository.go, so both callers had to pair the two by hand.

* refactor(persistence): unexport smartPlaylistCriteria methods

The type never leaves the package, so the exported names advertised an API
that callers outside persistence could never reach. Also disambiguates
where/orderBy from squirrel's SelectBuilder methods of the same name.

* fix(ui): cap the scrobble filter field width

fullWidth stretched it across the whole page next to 256px inputs. Bounded
at 40em, with two rows and a resize handle so JSON rules stay readable.

* refactor(ui): move scrobble filter input in UserEdit component

* feat(ui): add pt-BR translations for the scrobble filter

* fix(scrobbler): take the filter verdict before incPlay

incPlay mutates play counts and dates a filter can test on, so evaluating at
dispatch time let one play decide differently on either side of the increment:
a track could be scrobbled despite matching, or lose only its stopped report
and strand presence plugins. Reject limit/offset too, rather than silently
ignoring part of a rule copied from a smart playlist.

* fix(scrobbler): filter the report from an expired session

The expiry callback runs with a stub user carrying no filter, so evaluating
there always returned false and leaked the track to plugin scrobblers. That is
the normal path for clients that never send stopped, such as legacy Subsonic
now-playing. Carry the last verdict on the session instead.

* refactor(scrobbler): skip the now-playing enqueue instead of threading the verdict

Queuing an entry only to drop it at dispatch also cancelled a pending
announcement for the previous, unfiltered track, since the queue is keyed by
player and a new entry replaces the old one.

* fix(scrobbler): evaluate the filter regardless of active scrobblers

The verdict is stored on the session and dispatched at expiry, so skipping
evaluation when no scrobbler was active let a plugin enabled mid-session
receive a filtered track. The empty-filter guard above already gives servers
without scrobbling the same free path, so the shortcut only ever applied to
users who had a filter set.

fix(plugins): load plugin agents in CLI commands (#5959)
* feat(plugins): load plugin agents in CLI commands

A CLI that goes through core/agents saw only built-in agents: getEnabledAgentNames asks
Manager.PluginNames, which reads a map populated solely by Manager.Start, and only the
server calls that. On a plugin-using install the CLI's agent list was quietly short —
artwork explain --live could name deezer for an artist whose stored source was
external:apple-music, because apple-music was invisible to it.

Adds Manager.LoadPlugins, the read-only counterpart to Start: extism/wazero init plus
loadEnabledPlugins, without the folder sync, the error clearing, the cache purge or the
watcher. It follows what the read-only plugin commands already do — list, info and
validate read the DB and never start the manager — except that capabilities are detected
from the WASM exports, not declared in the manifest, so instantiating is the only accurate
source for what a plugin provides.

loadEnabledPlugins disabled a plugin and recorded LastError when a load failed. That is
right for the server and wrong for a diagnostic, so it is now gated on the read-only flag:
inspecting a plugin must not disable it.

No Subsonic router is required. Start log.Fatals without one, but the host function it
feeds already nil-checks and reports 'SubsonicAPI router not available' at call time, so a
plugin that reaches for it gets an error instead of the process dying. That Fatal's message
also claimed the DataStore was missing; it checks the router.

* fix(cli): correct the reprocess estimate's plugin caveat

imageAgentCount now receives a manager with plugins loaded, so the external estimate
already includes plugin image agents — but the disclaimer still said they were not
counted, which told operators the opposite of what the number meant.

Replaced rather than dropped: loadPluginAgents warns and continues when LoadPlugins
fails, and LoadPlugins is a no-op when plugins are disabled or no folder is set, so
there are still runs where plugin agents genuinely are not counted. The wording now
covers all three cases, and the stale comment above it said the CLI never starts the
plugin manager, which is what this branch changed.

Found by Codex on 648cf38e9.

* fix(plugins): load only the configured agents, and gate plugin init

Loading a plugin is not free: the service constructors create a KVStore or TaskQueue
database and a Storage directory for any plugin whose manifest declares those
permissions, and the plugin's own init then runs arbitrary code. loadEnabledPlugins
loads every enabled plugin, so inspecting artwork was starting scrobblers, schedulers
and lyrics plugins that could never supply an image.

Measured on a copy of a production library: 'artwork explain' created
apple-music/kvstore.db, nd-lyrics/kvstore.db and listenbrainz-daily-playlist/taskqueue.db.
The last one matters most — CreateQueue resets rows with status='running' to 'pending',
which against a live server sets up its in-flight tasks to run twice.

LoadPlugins now takes the names to load, and the artwork CLI passes the Agents list: a
plugin that is not a configured agent can never win, so there is nothing to gain by
instantiating it. The same two runs now create only apple-music, which is a configured
agent and therefore the cost of answering the question.

Init is gated separately on the caller's intent rather than on read-only. 'explain --live'
already means 'reach the provider', so it runs init; plain 'explain' and 'reprocess'
promise no external requests and must not. Documented in the --live flag help.

Found by Codex on 28eb39ac4.

* perf(cli): load plugin agents only when the selection can consult one

Explaining disc or media file artwork loaded every configured metadata plugin, though
neither resolver ever reaches an agent: resolveMediaFile is embedded-only and
discArtworkReader.selectImage refuses external outright. With --live that also ran plugin
init for a walk that provably cannot reach the network. The load now sits inside the
artist/album branch that already exists, so it is a move rather than a new condition.

reprocess did the same for a radio-only selection, whose estimate is unconditionally zero.
It is gated on needsImageAgents, which asks exactly what ExternalLookupsPerItem asks, so
the two cannot disagree. An artist/album test would look equivalent and would silently
zero the playlist estimate, whose generated grid resolves album art through those agents;
a test pins that, and reverting the predicate to a whitelist fails it.

Found by Codex on b78e67b07.

* docs(artwork): trim the comments this branch added to the project budget

Six blocks ran past the one-to-two line limit. The LoadPlugins doc was eleven lines over
three paragraphs, needsImageAgents spent two of its four explaining an alternative that was
rejected, and inspectOpts restated what LoadPlugins already says.

What went is reviewer-facing prose that belongs in a commit message: the enumeration of
what Start does that this skips, and why an artist/album predicate would have been wrong.
What stayed is the reasoning a future reader needs at that line, notably that instantiating
a plugin creates its declared services, and that playlists consume the album agent count.

* docs(artwork): correct the breaker comment after the recovery ramp

It still said a success re-closes the breaker, which stopped being true when closing
started requiring breakerRecoveries consecutive answers.

* refactor(plugins): rename the scoped-load options to transientLoad

inspect claimed the load was only looking, which is false when runInit is true: it
instantiates the plugin and runs its init, which may open sockets. transient is accurate
for every use of the field, and explains all three behaviours it gates. A load that will
not outlive the command has no business persisting findings, instantiating plugins it will
never consult, or starting background work it is about to tear down.

fix(artwork): ramp the external circuit breaker back up instead of closing on one answer (#5961)
* fix(artwork): ramp the external circuit breaker back up instead of closing on one answer

The breaker went straight from open to fully closed on a single non-transient response,
so recovery was a burst: the agent resumed at the limiter's full rate until five
consecutive failures reopened it. A not-found counted as that response, and a provider
that is blocking still answers the occasional request, so the cycle never settled.

Observed on a production library over 100 minutes with apple-music blocked. Of 232
responses, 228 were 403 and 4 were not-found, and those four closed the breaker four
times. Each close was followed by another open 1 to 3 seconds later, with about five
requests in between:

  00:59:05 closed -> 00:59:06 opened
  01:23:13 closed -> 01:23:16 opened
  01:41:21 closed -> 01:41:24 opened

Closing now needs breakerRecoveries consecutive answers, one per probe interval, and any
failure discards the count. A not-found still counts, because the provider did answer, but
it can no longer close the breaker by itself.

Unrelated to the plugin loading in the rest of this PR; it came out of investigating why
iTunes kept returning 403 while the breaker was open.

* fix(artwork): count only current-episode probes toward breaker recovery

The worker drains concurrently, so when the breaker opens there are already calls past
allow(), queued in the rate limiter or waiting on a response. Their answers arrive after
the open and reached the recovery counter, so breakerRecoveries of them closed the breaker
with no probe interval elapsed at all: the burst the ramp exists to prevent.

allow() now returns the open episode a call was admitted under, zero when the breaker was
closed, and only an answer whose generation matches the current episode counts. The
generation also invalidates a probe whose answer lands after the breaker closed and
reopened, which a plain probe flag would credit to the wrong episode.

The token never crosses the gateFunc seam: allow and record are both called inside
Worker.gate, so passthroughGate, tracingGate and offlineGate are untouched.

The regression test needs no fake clock. The race is an ordering, not a duration, so it is
reproduced by calling allow and record in the order concurrency produces, which is
deterministic where a goroutine-based test would pass on a lucky schedule.

Found by Codex.

* test(artwork): move the breaker ordering spec into the Ginkgo suite

The ordering regression does not need a fake clock, so it does not need the plain
testing.T runner either. That runner is only used here because testing/synctest requires
it; every other spec belongs in the Ginkgo suite.

The three specs left in worker_timing_test.go all drive the fake clock.

feat(cli): add an artwork command group for diagnosing and re-driving artwork (#5957)
* feat(artwork): add a resolution chain trace collector

* feat(artwork): trace the local priority chain

* fix(artwork): record priority candidates the chain never evaluated

* refactor(artwork): report never-evaluated candidates as skipped

* feat(artwork): trace external agents at the gate seam

* feat(artwork): add repository queries to enqueue by current source

* feat(artwork): expose a tracing resolver for the CLI

* feat(artwork): read a single queue row by item

The explain CLI must report whether an item is queued, at what priority and when it
retries; the queue repository could only be drained in eligibility batches, which
cannot see a row that is still backing off.

* feat(cli): add artwork explain

Prints why an item has the artwork it has: the stored state, its queue row, the
governing config, the resolver's priority-chain walk and the verdict. Offline by
default so a diagnostic run cannot add load to an external provider; --live asks
the agents for real. Playlists and radios do not walk a priority chain, so they
report that instead of an empty chain table.

* fix(artwork): trace an external tier that never reaches an agent

A configured 'external' token vanished from the chain when no enabled agent provided
images for that entity type, and for synthetic artists, leaving the trace unable to
say whether the tier was even considered.

* fix(cli): never state an artwork outcome the walk did not observe

A transient external failure traced as 'error' fell through to 'not resolved', which
is the most common state behind a missing-artwork report. It is now indeterminate, and
an offline win that a skipped higher-priority external candidate could have taken says
so instead of naming a winner the live chain might not pick.

* feat(cli): add artwork refresh

* feat(cli): add artwork reprocess

Bulk re-enqueues artwork by kind and/or by the source an item currently
resolves from, previewing the matched count and confirming before queueing.

The preview counts with CountBySource (rows matched) and reports separately
what EnqueueBySource inserted: its DO NOTHING conflict policy leaves an
already-queued row untouched, so the two numbers differ and the output must
not claim the skipped rows were re-queued.

An unknown --source is rejected against the sources present in item_artwork,
rather than silently matching nothing and printing a reassuring 0.

* fix(cli): cover the reprocess selection rule and validate sources table-wide

The reconciliation that makes --source alone target every kind was only
exercised through runReprocess, which no test calls: mutating it to
`all := reprocessAll` left the suite green. It is now reprocessSelectsAll,
covered for all three selectors.

Scoping source validation to the selected kinds made the same well-formed
filter valid or invalid depending on which other kinds were selected, and its
error read the same for a typo as for a source that simply does not apply to
the chosen kind. Validation is now table-wide: a typo still aborts, while a
valid-but-inapplicable source falls through to "Nothing matches".

Also: the prompt now counts only the kinds that reach an external agent as
external cost, and --dry-run on an empty selection reports a dry run.

* fix(cli): cover the reprocess --yes guard and preview the external cost

Mutating the --yes check to `if true` left the suite green, so the one bypass
of the confirmation was unverified. The choice is now reprocessConfirm(yes, in),
covered in both directions.

The external estimate only reached the operator through the prompt, which
--dry-run skips — hiding the number in the one mode that exists to show it
before committing. The preview now carries it, and the prompt drops the clause
when no lookup will be made.

An empty selection says so again under --dry-run.

* feat(artwork): add read-only queue and absent counters

Both are needed by the artwork status CLI: a queue breakdown by kind and priority, and
the absent totals split against the recheck cutoff.

* feat(cli): add artwork status

Reports the queue, where artwork currently resolves from, absent counts against the 24h
recheck window, and the stored config fingerprint versus the current one — the line that
turns 'why is my server re-resolving everything?' into one command.

fingerprint() and staleAbsentAge are exported so the CLI reports the values backfill
itself compares, instead of a second copy of the formula that can silently drift.

* fix(cli): lead the artwork status backfill line with the queued backlog

By the time anyone runs a diagnostic, backfill has usually already stored the new
fingerprint, so 'up to date' was printed while thousands of items churned through external
providers. The backlog is the finding; the fingerprint is context.

Also echoes the config inputs the fingerprint covers, so a change can be traced to the
setting that caused it, and pins the rendered rows: the Absent values, the queue TOTAL and
a queue-scoped kind/priority pair were all unasserted, so kindName and priorityName were
effectively untested. FingerprintInputs is now the single listing ConfigFingerprint hashes;
a pinned hash proves the value did not change.

* refactor(artwork): export the trace outcome vocabulary

The CLI hardcoded the outcome literals and the "external:" prefix, so renaming a
constant's value in core/artwork left cmd compiling and the suite green while
`artwork explain` silently degraded its verdict.

Renaming a value now fails the golden vocabulary test in core/artwork and the
explainResult tests in cmd.

* fix(cli): keep the re-enqueue warning when a backfill is already running

A stale stored fingerprint with items already queued is the worst state the
system can be in: a second full re-enqueue is pending on top of the one running.
The line carried the weakest wording of the three, and was untested.

* refactor(artwork): drop the unreachable breaker branch from the tracing gate

--live wires the tracing gate straight to passthroughGate, so errBreakerOpen can
never reach it; the test only passed by injecting a fake gate.

* refactor(artwork): delete the never-emitted not-reached outcome

Candidates after the winner are lower priority and say nothing about why a source
won; the ones that matter sit above it and are already recorded.

* refactor(artwork): make the trace nil-safe in one place only

add already handles a nil trace, so record's own guard was dead; Steps was the
odd one out and would panic where every other method tolerates nil.

* refactor(artwork): export the trace types directly

ChainTrace and TraceStep were unexported types re-exported through aliases,
which existed only so the CLI had a name to refer to them by. The types are
public API — Resolver.Steps returns []TraceStep and the CLI constructs a
ChainTrace — so name them that way and drop the indirection.

Encapsulation is unchanged: add, mu and steps stay unexported, so only this
package can write a step.

* refactor(cli): simplify parseArtworkKind with slices.Contains

Replaces a nested loop and a manual append with slices.Contains and the
repo's slice.Map helper. Same behaviour, same error message.

* fix(cli): print the absent artwork source under the name --source accepts

`artwork explain` rendered the stored empty source as "(absent)", while
`artwork reprocess --source` only accepts "absent", so pasting what explain
printed straight back into reprocess was rejected as an unknown source.

* refactor(artwork): own the kind list and the chain predicate in the package

Export RecheckKinds and add WalksPriorityChain so the CLI stops keeping its
own copies of both, and unexport externalCandidate, which nothing outside the
package consumes.

* refactor(cli): drop the artwork command's duplicated state and formatting

Reuse artwork.RecheckKinds and artwork.WalksPriorityChain, extract
newTabWriter and externalEstimate, fold reprocessSelectsAll into
selectedKinds, and derive the queue total and the walks-chain flag instead of
carrying them in the report structs.

* test(persistence): drop two artwork-queue specs that cannot fail

One seeded hash and source together and then asserted the two counts agree,
so its setup guaranteed the result; the other repeated the count-does-not-
enqueue property already covered by the CountBySource spec.

* refactor(artwork): rename Resolver to TracingResolver for clarity

* fix(cli): count playlists in the artwork reprocess external estimate

The estimate used WalksPriorityChain, which is true only for artist and album,
so a playlist-only reprocess reported "External lookups: none" and the
confirmation prompt dropped the external-cost warning. Playlists do reach the
network: through the m3u ExternalImageURL fetch when EnableM3UExternalAlbumArt
is on, and — verified by test — through the generated grid, whose tiles resolve
album art via the full album priority chain.

Adds artwork.MayFetchExternal, a config-aware predicate for "can this kind's
resolver reach the network", and uses it for the estimate. WalksPriorityChain
keeps its separate job of deciding whether explain prints a chain block.

* fix(cli): estimate artwork reprocess external lookups per agent, not per item

The reprocess prompt billed one external lookup per externally-capable item.
fetchArtistImage/fetchAlbumImage try every enabled image agent and stop early
only on a hit, and resolvePlaylist can fetch the m3u image and then resolve up
to four sampled albums for the grid, each walking the album agents again. The
number the operator confirmed could understate real provider traffic several
fold, in the prompt whose whole job is to stop a provider flood.

ExternalLookupsPerItem now multiplies by the visible image-agent count and adds
the playlist grid factor. It stays a floor: the CLI never calls Manager.Start(),
so the plugin registry is empty and plugin-provided agents are dropped by
getEnabledAgentNames. On an install with 5 agents of which 3 are plugins the
count is well under the truth, so the wording is now "at least N" rather than
"up to N" — a zero visible count still bills one lookup for the same reason.

Fixing the plugin visibility is out of scope: Manager.Start() needs a Subsonic
router and writes to the DB via syncPlugins, breaking this command group's
read-only guarantee.

* fix(cli): state the artwork reprocess estimate as an estimate, not a bound

Neither bound is true. A ceiling is false because plugin agents are invisible to
a CLI that never starts the plugin manager, and a floor is false because a local
hit ends the walk before any agent is asked and a hit on the first agent skips
the rest. "at least N" traded one wrong claim for another.

The line now names its blind spots instead:

  External lookups: ~340 estimated (plugin agents not counted; local hits may
  need fewer).

The same line is reused in the confirmation prompt, and the zero case still
reads "External lookups: none." with the prompt dropping the clause entirely.
The count itself is unchanged.

* fix(cli): account for every configured agent in artwork explain

The Agents: line printed the raw config while the Chain only showed the agents the CLI could
construct, with nothing explaining the gap: plugin agents are never registered in a CLI that does
not start the plugin manager, and a built-in without credentials returns nil. Three of five agents
could vanish, including ones ranked above the one shown.

Also treat a live external error before the winning hit like the already-handled would-try case:
the resolver serves such a hit provisionally and retries later, so the verdict is indeterminate.

The Result line is still not qualified when an unavailable agent might have won; that needs agent
ranking, and is left to the follow-up that makes the CLI load plugin agents for real.

* fix(cli): do not call an external artwork win indeterminate

explainResult qualified the verdict whenever an external OutcomeError
appeared before the winning hit. When a later external agent returns an
image, fetchArtistImage/fetchAlbumImage discard the earlier error, so
extError is false: the worker settles the item and schedules no retry.
Telling the operator it may resolve differently on a retry was wrong.

The warning is only correct when a lower-priority local source won while
an external error was recorded, which is the case that carries extError.

* fix(cli): accept --source absent when nothing is currently absent

validateSources checks the requested sources against the ones item_artwork
actually uses, to catch a typo. The reserved empty source (spelled 'absent' on
the CLI) is a valid filter even when it matches nothing, so a scheduled
'artwork reprocess --source absent --yes' stopped working the moment the
library finished resolving. Treat it as intrinsically valid and let the
existing zero-match path report it.

* feat(artwork): explain disc and media file artwork from the CLI

`artwork explain` rejected `dc` and `mf` because it validated against RecheckKinds,
the list of kinds the backfill revisits. Those are different questions: a kind with no
recheck path still has artwork someone can report as wrong.

Disc artwork now walks DiscArtPriority under a trace, so explain reports which entry won
and why the others lost, including entries that map to no source at all (external is
unsupported, a disc with no subtitle, an album folder with no images). Media file artwork
traces its single embedded candidate, separating "EnableMediaFileCoverArt is off" from
"the track has no embedded art" — stored state cannot tell those apart.

Each command now validates against the kinds it can actually serve: explain takes all six,
refresh takes artwork.RefreshableKinds (which nativeapi now shares instead of keeping its
own copy), reprocess still takes RecheckKinds. Disc artwork stays out of refresh: the
worker cannot resolve it, so the queue row would be rejected on every drain.

WalksPriorityChain becomes Explainable, and ResolveArtist/ResolveAlbum collapse into
Resolve(kind, id).

* refactor(artwork): one disc-artwork walk for serving and explain

resolveDisc duplicated the loop selectImageReader already ran: try each source in
priority order, take the first that yields an image. The serving path and the CLI
diverged on two details as a result — only selectImageReader checked ctx between
candidates and logged each attempt.

Both now call discArtworkReader.selectImage, which takes the chainState the CLI already
uses for the other kinds. The serving path passes an untraced one, whose nil trace makes
recording a no-op. selectImageReader had no other caller and is gone.

The disc tests move from fromDiscArtPriority to discCandidates, so they assert the skip
reason for an entry that maps to no source rather than that it silently vanished, and
cancellation mid-walk is now covered.

* fix(artwork): reject a nil reader in the resize cache instead of panicking

resizedItem.Reader closes what open() hands back, so an open() that reports "no image"
as (nil, nil) rather than an error takes the request down with a nil-pointer panic. Every
caller returns an error today, and no test covered it: the resolution e2e harness stubs
the resize reader out entirely, so no e2e path reaches this code at all.

Guard it and cover Reader directly.

* refactor(artwork): move the keeps-state fact into core, drop a redundant guard

keepsArtworkState lived in package cmd and re-derived by hand what RefreshableKinds
already encodes: the same five-of-six kinds. It is now artwork.KeepsState, beside the
list, with a test pinning the two together — nothing else stopped them drifting, and a
drift would have explain report stored state for a kind that keeps none.

serveDisc's closure also hand-rolled a nil-reader error that both consumers of open()
now produce themselves: serveSource for a full-size request, resizedItem.Reader for a
resized one.

* fix(artwork): route disc candidates through the shared resolvers

openCandidate ran its own source loop and threw the error away, so a disc track that
exists but cannot be parsed traced as "miss" — indistinguishable from a track with no
embedded art. fromTag and fromFFmpegTag already report that case as errSourceUnreadable;
only this loop was discarding it. Telling those two apart is what the trace is for.

Candidates now carry a resolve func instead of raw sources: embedded goes to
resolveEmbedded, and the folder-backed entries to resolveFolderSource, extracted from
resolveFolderFile so both callers classify an unopenable file the same way. openCandidate
and its absolute-path special case go away with it.

Disc's own fromExternalFile and fromDiscSubtitle still swallow open errors, so folder
candidates cannot report unreadable yet; that is a change to their error contracts.

* fix(artwork): report an unreadable local candidate as indeterminate

processor.acquire treats resolution.localError exactly as it treats extError: a fault is
not a definitive "no image", so it retries instead of settling absent. explainResult
qualified only the external case, so a chain that ended on an unreadable local candidate
printed "not resolved" — the one verdict that says the walk was conclusive.

The qualification belongs only to the unresolved branch. chainState.try stamps extErr onto
a hit and deliberately drops localErr, so an unreadable step followed by a hit is settled
as found and must not carry a warning; a test pins that.

feat(insights): report the app store or hosting platform via ND_PLATFORM (#5956)
* feat(insights): report the app store or hosting platform via ND_PLATFORM

Insights had no way to tell where an instance is deployed. The existing `os.package` field is written only by our own packagers and holds just `deb`, `rpm` or `msi`, so it answers "which installer", not "which platform". Overloading it would mix two unrelated dimensions in the same field.

This adds a separate top-level `platform` field, self-declared by the deployer through the `ND_PLATFORM` environment variable. App stores and hosting providers (ZimaOS, PikaPods, TrueNAS, Unraid, and others) generally deploy our container image unmodified and can only inject environment variables, so an env var is the one marker they can all set. It is deliberately not a config option: it is a packager marker, not something users should tune, and it stays out of the config surface.

Both values are now whitespace-trimmed. The msi packager writes the file with `echo`, so `os.package` has been arriving as `"msi\n"` and sorting separately from `"msi"` in any aggregation.

* test(insights): isolate hostingPlatform specs from an inherited ND_PLATFORM

The spec asserting an empty result read the real environment, so it failed on any machine that already had ND_PLATFORM set. Unset it per-spec, using Setenv first so Ginkgo restores the original value on cleanup.

fix(artwork): serve images whose format has no registered decoder (#5952)
* fix(artwork): serve images whose format has no registered decoder

The new pipeline derives dimensions, mime and the placeholder hashes at
resolution time, so a decode became a precondition for recording artwork at
all. An image in a format Go has no decoder for therefore failed acquisition,
retried until the 12h budget ran out, and then settled as absent, serving a
placeholder from that point on. The old pipeline decoded only to resize and
fell back to the original bytes when that failed, so these covers used to work.

A local file is picked by matching an image extension, so bytes it cannot
decode are most likely a codec we lack: image.ErrFormat on a folder, upload or
embedded source now yields an Artwork row carrying just the hash and mime, and
the bytes stay servable. An external response carries no such guarantee, so it
still fails and retries rather than pinning a non-image body as a cover. A
corrupt image of a known format and an over-cap declared size still fail, so
the decompression bomb guard is unchanged. Absent rows recorded by earlier
builds are re-resolved by the existing stale-absent recheck within a day, so
no epoch bump is needed to repair them.

Reusing a stored image now re-decodes when it carries no dimensions, so a
row recorded while a decoder was missing can still be upgraded later.

Registers jxl, heic and heif in mime_types.yaml: image detection resolves the
extension through the host MIME table, and the Alpine release image ships no
/etc/mime.types, so those covers were never recorded in folder.ImageFiles
there and never reached the pipeline at all.

* fix(artwork): never record empty bytes as artwork

image.DecodeConfig returns image.ErrFormat for an empty payload just as it
does for a codec with no registered decoder, so a zero-byte cover file was
recorded as found artwork and served as an empty response instead of falling
back to the placeholder. A truncated image of a known format already fails
with unexpected EOF rather than ErrFormat, so only the empty case needed the
guard.

feat(jellyfin): add System/Endpoint so Finamp's connection test passes (#5955)
Finamp's connection test GETs /System/Endpoint and treats anything other
than a 200 carrying an IsInNetwork key as "not a Jellyfin server", so the
test failed against Navidrome and dual-connection setups could never
switch to the local address.

IsInNetwork mirrors Jellyfin's default LAN set (NetworkManager with no
LocalNetworkSubnets configured): loopback, the RFC 1918 ranges, fc00::/7
and fe80::/10. Notably that set omits 169.254.0.0/16, so Go's
IsLinkLocalUnicast is deliberately restricted to its IPv6 half.

IsLocal mirrors HttpContext.IsLocal(): the caller shares the connection's
local address, not merely "is loopback". It falls back to the loopback
check when the local address is unavailable.

fix(plugins): stop reporting plugin call failures as not-found (#5953)
* fix(plugins): stop reporting plugin call failures as not-found

MetadataAgent joined agents.ErrNotFound onto every failed plugin call, so a
transport fault was indistinguishable from a definitive miss. The artwork
circuit breaker treats a not-found as a successful, definitive answer and
resets its failure counter, so it never opened for a failing plugin and kept
calling it on every request. Observed with the apple-music plugin against
prod: ~900 iTunes 429s in 27 minutes with the breaker never tripping.

Return the underlying error instead. The genuine empty-result branches still
return agents.ErrNotFound, and agent fallback is unaffected because
callAgentMethod/callAgentSliceMethod continue on any error, not only on
ErrNotFound.

* test(plugins): fold duplicate metadata agent error specs into one table

The error-handling container drove all 11 MetadataAgent methods twice: once
to assert the message, once to assert the failure is not an ErrNotFound. The
argument lists were identical, so each method cost two WASM instantiations for
one method's worth of coverage, and a new capability had to be registered in
two places to stay guarded.

Fold both assertions into a single DescribeTable, document the ErrNotFound
contract at the sentinel where agent implementers will read it, and collapse
breaker.record's hand-inlined predicate onto isTransientExternal, which it
already duplicated by hand with a keep-in-sync comment.

* fix(plugins): keep an unimplemented plugin method a definitive miss

Returning the raw plugin error made errNotImplemented and errFunctionNotFound
look like provider faults. Every MetadataAgent satisfies ArtistImageRetriever
and AlbumImageRetriever regardless of what the plugin actually exports, so
artwork resolution calls those stubs on a partially-implemented plugin: each
call counted toward the artwork circuit breaker and kept the item in the retry
queue instead of settling it absent.

Map both sentinels back onto agents.ErrNotFound, joined so the underlying
reason survives for diagnostics, and leave real call failures untouched. This
matches what ScrobblerPlugin already does for the same two sentinels.

The partial-implementation specs asserted only MatchError(errNotImplemented),
which the previous errors.Join satisfied incidentally, so nothing caught the
lost not-found semantics. They now assert both and are folded into one table.

* test(plugins): cover the missing-export arm of agentErr

The partial-metadata-agent fixture registers through the Go PDK, which exports
every method and answers with the not-implemented code, so no fixture reaches
the errFunctionNotFound branch. Building one would mean hand-writing Extism
exports to deliberately omit a function, which tests the manager's function
lookup rather than the mapping this PR added.

Cover agentErr directly instead: both sentinels classify as a definitive miss,
a call failure and a non-zero exit stay faults, and the underlying reason
survives in every case.

* fix(artwork): stop counting a cancelled run against the circuit breaker

callPluginFunction returns ctx.Err() when a plugin call is cancelled, and that
reached breaker.record as an ordinary error, so cancellations counted toward
the five consecutive failures that open a gate. A cancellation says nothing
about the provider, so it now neither counts nor clears the failure run.

Deliberately scoped to breaker.record rather than isTransientExternal: the
latter also drives whether the queue item is rescheduled, and a cancelled item
must still be retried rather than settling absent. context.DeadlineExceeded is
left counting as a fault, since a provider that blows the budget is one worth
backing off from.

Reachable today only at shutdown, where the in-memory breaker state is
discarded anyway. It becomes live the moment Worker.gate is used on a
request-scoped context, which is why it is worth closing now.

fix(instant-mix): top short mixes up instead of returning what the first source found (#5951)
* fix(instant-mix): top short mixes up instead of returning what the first source found

SimilarSongs returned the first non-empty source's tracks, however few. For a
thinly-represented artist that meant a 3-track mix no matter the requested count:
the artist agent found nothing, the similar-artists fallback matched 3 library
tracks, and `len(res) > 0` kept seed-track sampling from ever running.

Clients treat that as a failed mix and retry with a bigger limit forever. Finamp
cycles limit 34 through 472 and starts over, ~1 request every 2s indefinitely,
each one re-hitting Last.fm, Deezer and AudioMuse.

Sources are now chained rather than raced: each one tops the mix up until it
holds count tracks, so the agent's picks, the similar-artists fallback and
seed-track sampling all contribute instead of the first one winning outright.

* refactor(external): move similar-songs code to its own file

provider.go held two distinct concerns: artist/album external metadata and the
similar-songs mix pipeline. The mix code was already one contiguous block, and
maxSeeds, maxSimilarSongs and dedupByID were used by nothing else.

Moved SimilarSongs and its helpers to provider_similarsongs.go, matching the
existing provider_similarsongs_test.go. Pure code motion: the moved block is
byte-for-byte unchanged and provider.go has no additions, only deletions.

* fix(instant-mix): dedup before deciding a mix is full

topUp measured res before deduplicating it. Matcher.MatchSongs deliberately
re-emits a library track when the same input song repeats, and the similar-artists
fallback can reach one track through several artists, so len(res) could equal count
while holding fewer unique tracks. That returned a mix with duplicates in it and
stopped the top-up early; the caller then deduplicated and handed back a short mix,
which is the client retry loop this branch set out to fix.

Deduplicate first, so the length check counts what the client will actually receive.

* perf(instant-mix): skip a fallback once the mix is already full

The artist path nested one topUp inside another, so the inner one measured only
similarSongsFallback's own result against the full count. With 49 agent matches and
one fallback match for count=50 the mix was already full, yet seed-track sampling
still ran and fired up to five GetSimilarSongsByTrack calls whose results the outer
topUp then truncated away.

topUp now takes the sources as a variadic list and re-checks the accumulated mix
before each one, so a later, costlier source only runs while the mix is still short.
That also flattens the artist case: the agent, the similar-artists fallback and
seed-track sampling are now three peers in one chain instead of two nested calls.

* fix(instant-mix): count distinct tracks when picking the fallback mix

similarSongsFallback stopped after count picks from the weighted chooser, but a
track can sit in that chooser once per artist listing it in their top songs, and
Pick removes the entry it returns. Repeats therefore consumed pick slots and left
unique candidates stranded, so the batch could come back short of count. On the
track path this is the only source, so that short mix reached the client and kept
the retry loop alive.

Track the ids already picked and keep drawing until count distinct tracks are held
or the chooser is empty.

* fix(instant-mix): match the whole agent response before trimming

MatchSongs was capped at count, and it re-emits a track when the same song repeats,
so [A, A, B] with count=2 returned [A, A] and never reached B. topUp then shrank
that to [A] and, with an empty or overlapping fallback, the mix stayed short even
though B had been available all along. seedMix already matched its full merged set
for this reason; mixFromAgent now does the same and leaves the trim to topUp.

Also drop the capacity hint on the picked-ids map. It was sized from the caller's
count, which CodeQL flags as an allocation sized by user input (go/uncontrolled-
allocation-size). SimilarSongs clamps count to maxSimilarSongs long before this
point, so the hint bought nothing worth the alert.

* refactor(instant-mix): tidy the mix chain and its specs

Quality pass over the new code, no behaviour change:

- topUp: drop the first-vs-last error bookkeeping (the value is only read when the
  mix is empty, so the distinction is unobservable) and the redundant nil guard
  (dedupByID returns nil for an empty result, so both branches already agreed).
- mixFromAgent: assign through the if-scoped err instead of a second error name.
- Hoist the similar-artists fallback closure written verbatim in two switch arms.
- Use map[string]struct{} in the pick loop, matching dedupByID in the same file.
- Trim three comments back within budget; two restated the line below them and one
  carried commit-message rationale.
- Tests: add an ids() helper for the ID assertion repeated seven times, and fold
  the track-entity stub block copied into three specs into stubTrackEntity. The
  block hard-coded .Twice() on GetEntityByID, which pinned an implementation
  detail no spec asserts.

* revert(instant-mix): inline the similar-artists fallback closure again

Hoisting it to a shared artistFallback var moved the call away from the arm that
uses it and saved nothing: each arm reads better spelling out its own sources.

feat(instant-mix): support album, playlist and genre sources (#5948)
* feat(agents): local agent genre-hint similar songs fallback

* feat(external): playlist instant mix via seed-track sampling

* test(external): cover playlist mix never-empty fallback and maxSeeds cap

Adds coverage for the empty-match seed fallback and the maxSeeds
call cap on GetSimilarSongsByTrack, per code review finding.

* feat(external): genre instant mix via seed-track sampling

* feat(external): album instant mix falls back to AudioMuse track similarity

* feat(external): artist instant mix falls back to seed-track sampling

* fix(jellyfin): route genre seeds through instant mix instead of empty

* feat(jellyfin): add /Albums/{id}/Similar route for albumMix radio

* perf(external): bound playlist seed sampling to a random N

samplePlaylistTracks loaded an entire playlist's joined rows just to keep
5 random seeds; push the bound and randomization into the query instead,
matching the other samplers (GetRandom/GetAllByTags with Max).

Fixing this surfaced a real bug: resetSeededRandom's SEEDEDRAND rewrite
assumed every table's id is TEXT, but playlist_tracks.id is an INTEGER
position, so the random sort silently dropped every row. Cast the id to
TEXT before hashing (no-op for the other, TEXT-id tables).

Also trims a changelog-flavored comment and a duplicated rationale in
server/jellyfin/similar_test.go.

* refactor(external): parallelize seed mix and dedup mix helpers

Run the up-to-5 per-seed GetSimilarSongsByTrack calls concurrently (errgroup),
route the four container cases through a shared seedMix helper, flatten the
genre lookup, and sample playlist seeds without forcing a smart-playlist
rebuild. Share the media-file->Song mapping in the local agent.

* perf(agents): use the indexed genre filter for local similarity

Replace GetAllByTags (a json_tree scan of every media_file row) with the
media_file_tags semi-join from #5940, deriving the seed's genre tag ids
locally since they hash from (name, value).

Also carry the library id and the recording MBID on the returned songs:
the matcher resolves by id first and looks up mbz_recording_id, so the
release-track id it got before matched nothing and the local fallback
silently returned no songs.

* refactor: drop redundant MBID and fold mixFromSeeds into seedMix

The local agent returns library tracks, so the id alone resolves them in the
matcher's first phase; the MBID was never consulted. mixFromSeeds had no
caller other than seedMix.

* docs: trim redundant comments

* fix(jellyfin): adopt the GUID id codec in the merged similar routes

getSimilarAlbums still used resolveItemID/DecodeID, which #5942 replaced with
itemIDParam; its tests passed raw ids that the strict codec now rejects.

* fix(external): guard non-positive counts and blend every seed

A negative Subsonic count reached matched[:count] and panicked. The matcher
also keeps input order and stops at count, so seed-grouped results let the
first seed fill the whole mix; interleaving gives every seed a share.

Drops the duplicate playlist-track mock in favour of tests.MockPlaylistTrackRepo,
which pages like the real repository and records the query options.

* fix(external): refresh smart playlists before sampling seeds

A smart playlist materializes no playlist_tracks until it is evaluated, so
sampling without the refresh mixed an empty seed set. The refresh is a no-op
for regular playlists, inside the refresh delay, and for non-owners.

* fix(external): skip missing tracks and a nil playlist-track repo when sampling

Tracks() logs and returns a nil repository when its own lookup fails, so the
chained GetAll panicked. Seeds can also reach the mix verbatim when the agents
find nothing, so a missing file would surface as an unplayable entry.

* fix(jellyfin): never report the seed album as its own similar album

The sampled-seed fallback returns the album's own tracks, which similarAlbums
mapped straight back to the requested album, often as the only result.

* test(agents): assert the genre predicate instead of relying on the mock

MockMediaFileRepo ignores QueryOptions.Filters, so the spec passed even with
no genre filter at all. It now checks the generated predicate carries the
seed's own tag id, the indexed join and the missing exclusion.

* fix(external): clamp the requested count before it becomes a query limit

Subsonic passes the client's count through unbounded. At MaxInt64 the local
agent's count+1 overflows negative, and GetRandom omits the SQL limit unless
Max is positive, so one request would hydrate every matching track. 500 is
what the widest caller (similarAlbums, limit*5) legitimately asks for.

* fix(external): deduplicate playlist seeds by media file

A playlist can hold the same file at several positions, so sampling its rows
could seed the mix twice: a wasted agent call, and a duplicate track whenever
the seed fallback kicks in.

* fix(external): drop tracks two seeds both recommend

The matcher re-emits a track when two inputs are identical, so overlapping
recommendations took several slots in the mix. Match the whole merged set and
dedup before trimming. Playlist sampling now over-fetches before its own
dedup, so repeated positions cannot collapse the seed count.

* test(external): make the seed-blend assertion independent of the shuffle

It matched four tracks and kept two at random, so both could come from the
first seed once in six runs. Keeping three of the four makes a seed-two track
unavoidable.

* fix(external): seed artist mixes from every credited role

media_file.artist_id is the deprecated primary artist, so an artist credited
only on the album, as on compilations, sampled no seeds at all. Use the same
participant filter the artist listings use.

* refactor(external): drop the now-vestigial seed interleaving

Matching the whole merged set removed the early truncation the interleave
guarded against, and the shuffle before the trim makes input order irrelevant.
Its comment described the old behaviour.

* test(agents): give the id-mapping fixture a matching genre

The related track carried no genre, so the real query would never return it;
the spec only passed because the mock ignores QueryOptions.Filters.

* test(agents): drop the MBID from the id-mapping fixture

Local agent candidates are non-missing library rows, so the matcher always
resolves them in its id phase and never reads the MBID. The field guarded a
regression that could not change behaviour.

* test(agents): remove unnecessary comment about MBID in GetArtistTopSongs test

* fix(jellyfin): only let a not-found entity fall through in getInstantMix

Discarding the error conflated a genre id, which never resolves, with a real
lookup failure, which then made a provider call that fails the same way.

* test: pin the invariants the specs only appeared to cover

The missing filter was asserted by substring, so flipping it to true passed
everywhere, including the spec named for it. Matching the whole merged set,
the local agent's over-fetch, and its no-genres early return had no coverage
at all; each is now pinned by a spec that fails when the code is broken.

* test: make the remaining specs say what they actually guard

The playlist-track spec named a sort whitelist it does not exercise; it guards
the integer-id CAST, so it now asserts no rows are dropped. The maxSeeds cap
passed with either bound removed, and the over-fetch was pinned by its literal
value rather than the duplicate positions it exists for. Also drops setup the
count guard returns before reaching.

* fix(external): fall back when the agent's picks are not in this library

A non-empty answer whose songs are all absent locally matched nothing and was
returned as-is, so the mix came back empty with sampleable source tracks
sitting right there.

* refactor(external): name the agent-then-fallback flow once

Each entity case repeated the same error and emptiness plumbing around the
matcher. mixFromAgent states it once and each case supplies only what differs:
how to ask, and what to do when the answer is unusable.

refactor(jellyfin): emit real 128-bit GUIDs as item ids (#5942)
* test(jellyfin): use canonical ids in dto fixtures

Fixtures used short placeholder strings, which are not valid Navidrome ids. Deriving them from
id.NewHash keeps the labels readable while exercising the real id shape.

* test(jellyfin): use canonical ids in handler fixtures

Fixtures used short placeholder strings, which are not valid Navidrome ids. Deriving them from
id.NewHash keeps the labels readable while exercising the real id shape. Playlist entry positions
stay decimal, matching the integer playlist_tracks.id column.

* test(jellyfin): use canonical ids in e2e fixtures

Fixtures used short placeholder strings, which are not valid Navidrome ids. Deriving them from
id.NewHash keeps the labels readable while exercising the real id shape.

* test(jellyfin): use canonical ids in audiomuse fixtures

audiomuse_test.go passes ids as bare function args (mf(id, ...), call(query, user)) rather than
via ID: struct-literal fields, so the original grep-built file list missed it. Same conversion as
the rest of the fixtures: fake labels through id.NewHash via testID.

* test(jellyfin): convert remaining nonexistent-id sentinels in e2e tests

Reviewer swept for enc("literal") sites the brief's dto.EncodeID grep missed. These "does not
exist" fixtures must stay well-formed GUIDs under the strict codec, or the test degrades from
"resolves to nothing" to "empty path segment".

* refactor(jellyfin): emit real 128-bit GUIDs as item ids

Navidrome ids are now a canonical 22-char base62 encoding of exactly 128 bits, so they map
losslessly onto Jellyfin GUIDs. Previously the API hex-encoded the id string itself, producing
44 hex chars where Jellyfin uses 32.

Integer library ids, the synthetic playlists folder, and playlist entry positions (a
playlist_tracks.id, an integer column) aren't 128-bit values, so they get a reserved GUID space
tagged by kind. DecodeID is now strict: malformed input returns an empty string instead of
passing through unchanged.

BREAKING: Jellyfin clients see entirely new item ids.

* fix(jellyfin): 404 malformed playlist ids instead of silently creating

updatePlaylist decoded a malformed playlistId to "", the same sentinel core/playlists.Create
uses to mean "make a new playlist" — the overload createPlaylist deliberately relies on. A
malformed id now 404s before reaching Create.

Also tightens id-codec test fixtures: several tests set chi params to a raw canonical id, which
now decodes to "" and only passed because the fakes ignore the id argument; and a batch of
not-found sentinels now use well-formed-but-nonexistent GUIDs so they exercise the intended path
instead of the malformed-id path. READMEs "lossless" claim softened to note the reserved space.

* refactor(jellyfin): drop the id truncation workaround

Finamp's saved-queue packing keeps the first 16 bytes of each item id. That was lossy only
because our ids were 44 hex chars; now they are 32, so the packing round-trips exactly and the
server-side prefix recovery is dead code.

Removes an indexed range scan per restored queue and the ambiguous-prefix path that could
resolve to the wrong item.

* fix(jellyfin): emit ServerId and PlaySessionId in Jellyfin's id format

Jellyfin serializes GUIDs without dashes; ServerId was emitting the dashed UUID form. A
ServerId persisted before this change is normalized on read rather than rewritten.

PlaySessionId was emitting a raw internal id instead of the encoded form.

BREAKING: the ServerId change makes clients treat the server as new, so users re-login once.

* fix(jellyfin): 404 on undecodable id filters instead of widening the query

DecodeID collapsed an absent param and an undecodable one into the empty string, and downstream
an empty id means no filter. A client sending a stale pre-upgrade id therefore had its filter
silently dropped: ParentId, ArtistIds and AlbumArtistIds each returned the whole library instead
of a scoped result. Every existing client hits this on first launch after the id format changes.

Scalar id params now distinguish the two cases and report not-found. List-valued params already
failed closed. EncodeID logs a diagnostic when a non-empty id is not canonical, which should not
happen post-migration and would otherwise ship an unaddressable item silently.

* test(jellyfin): drop comments that restate the spec names

* refactor(jellyfin): decode reserved GUIDs from bytes, not hex strings

DecodeID already had the 16 decoded bytes, then re-derived the kind tag and payload by slicing the
hex string and parsing it a second time. Reading them off the byte slice matches how the format is
specified and removes the duplicate parse.

Bounding the payload inside encodeReserved gives both encoders the 32-char guarantee, which only
EncodePlaylistEntryID enforced before.

Playlist entries now decode through DecodePlaylistEntryID, which rejects other kinds. The tag was
being encoded and then discarded, so a song id passed as an EntryId reached RemoveTracks as a
playlist_tracks position.

Drops the per-field log.Warn from EncodeID: it sat in a leaf codec without a ctx and would emit
once per item per request on exactly the bad-data population it was meant to surface.

* refactor(jellyfin): make DecodeID report whether the id was decodable

DecodeID returned the empty string for both an absent param and an undecodable one, and
downstream an empty id means no filter. That conflation is what let a stale id widen /Items to
the whole library; it had been patched at two call sites, leaving three different policies for an
undecodable id in one package and ~16 handlers correct only because a repo Get("") happens to fail.

Returning (string, bool) makes the ambiguity unrepresentable, and the compiler forces each of the
~22 sites to decide. URL params share one itemIDParam helper that 404s; id lists go through
DecodeIDs, which is all-or-nothing because dropping bad entries would empty a list and make its
len() > 0 filter gate vanish — the original bug by another route.

A well-formed but unknown id is still 200 with zero results; only malformed ids 404. Malformed
ids now also 404 on the image and similar/instant-mix routes, which previously answered with a
placeholder or an empty list.

fix(cli): accept absolute paths in selective scan --target (#5947)
* fix(scanner): accept absolute paths in selective scan --target

The scanner's fs.FS only accepts paths relative to the library root, so an
absolute --target path (e.g. 2:/jukebox/collection) failed with an opaque
"invalid argument" error. Rebase absolute targets onto the library root
before scanning; relative paths are unchanged.

Fixes #5943

* refactor(scanner): simplify libraryRelativePath with IsLocal and slice.ToMap

* fix(scanner): make libraryRelativePath cross-platform

Windows CI failed: the tests hardcoded Unix-style absolute paths, which are
not absolute on Windows, and filepath.Rel yields backslash-separated paths
that the io/fs-based scanner FS rejects. Build the test paths with
filepath.Abs so they are absolute on every OS, and normalize the rebased
result with filepath.ToSlash.

* fix(scanner): resolve relative library root before rebasing target

filepath.Rel cannot rebase an absolute target onto a relative library root
(e.g. the default MusicFolder=./music), so an absolute --target was left
unchanged and rejected by the rooted io/fs. Make the library root absolute
first; it resolves against the same cwd as the scanner's fs.

feat(artist): add Share and Download actions to the Artist detail page (#5944)
* feat(ui): add Share button to artist detail page

* feat(ui): add Download button to artist detail page

* fix(ui): scope artist share/download to album-artist content

Gate the artist Share/Download actions on album-artist stats and show the
album-artist size, since ZipArtist and the share query only cover
album_artist_id songs. Previously the total (role-inclusive) size was shown
and guest-only artists could produce an empty archive. Applies to the artist
toolbar, the shared context menu, and the download dialog title.

* fix: match artist download/share to album-artist participation

ZipArtist and the artist share query filtered the deprecated album_artist_id
column, which only stores the first album artist of a track. Secondary
album-artists (co-credited but not first) got an empty download/share even
though the UI offered it. Filter by the album-artist role participation
instead, matching the artist's album-artist stats used to gate the actions.
Also cover the artist-specific size branch of the download dialog.

* fix(share): scope artist shares to the owner's libraries

The artist share query broadened to album-artist participation, which could
pull a secondary album artist's tracks from libraries the (non-admin) share
owner cannot access into the public share. Load the artist share as the owner
so their library access is applied, mirroring how playlist shares already work.
Adds a repository test covering co-album-artist inclusion and library scoping.

* test(share): assert album participation branch of artist shares

Link the co-album-artist fixtures to albums and assert share.Albums (used by
Subsonic getShares) includes the accessible album and excludes the one in a
library the owner cannot access, so the album participation + scoping branch
is covered too.

* fix: exclude missing files from artist download/share actions

An artist's stats still count files that went missing, so the toolbar/context
menu could offer Download/Share for an artist whose files are all gone, while
the share query (missing=false) returns nothing and downloads open dead paths.
Hide the actions when the artist is missing and exclude missing files from
ZipArtist, matching the share semantics.

* refactor: dedupe artist download-size and share-owner lookups

Extract the 'album-artist download size (or none when missing)' rule into a
single artistDownloadSize() helper shared by the toolbar, context menu, and
download dialog, and factor the duplicated share-owner context lookup into a
shareRepository.ownerContext() method used by both the artist and playlist
share cases.

* refactor(ui): move artistDownloadSize helper to common

utils is for domain-agnostic, potentially portable code; this helper is
Navidrome-specific (artist stats shape), so it belongs in common. Consumers
import it directly from common/artist to avoid pulling in the common barrel.

feat(jellyfin): send a synthetic placeholder blurhash for unresolved artwork (#5941)
* refactor(artwork): let callers pin the blurhash component counts

* feat(artwork): synthesize a unique placeholder blurhash from a seed

* fix(artwork): base the synthetic-hash no-collision guarantee on the prefix, not length

The prior comment and test claimed a synthetic value could never collide with a
real one because it's always shorter. That's false: components() targets ~16
tiles by scaling one axis down as the other hits the 9 cap, so an extreme
aspect ratio (e.g. 10x200) collapses to 1x9 = 9 components, which encodes to
the same 22 characters as a 3x3 synthetic hash. The old test only exercised a
square 64x64 gradient, so it never caught this.

The real guarantee is structural, not length-based: the first character encodes
shape as (xComp-1)+(yComp-1)*9, and components() derives xf*yf = 16 exactly
before flooring/capping (xf = sqrt(16w/h), yf = xf*h/w = sqrt(16h/w), so
xf*yf = sqrt(256) = 16). Two factors both in [2,3) can't multiply to 16, so
Encode can never derive 3x3 - the synthetic prefix 'K' is structurally
exclusive to Synthetic. Replaced the length-based test with one that sweeps
extreme aspect ratios and asserts no real encode ever produces prefix 'K',
alongside the assertion that Synthetic always does.

* feat(artwork): tint a synthetic blurhash from a base colour

Parses baseColor into HSL and clamps saturation/lightness so the tint
stays muted; per-cell hashing (unchanged) is what keeps a shared tint
across an album's tracks from colliding, as the new 1M-seed spec
proves under a single fixed colour.

* fix(artwork): trim over-long comment in synthetic blurhash test

Review flagged the collision spec's comment for exceeding the 2-line
budget; the Finamp rationale it restated already lives in the design
doc and commit history.

* feat(jellyfin): send a synthetic blurhash for unresolved artwork

Clients render nothing where a placeholder belongs when ImageBlurHashes
is omitted for pending artwork. primaryImage now synthesizes a value
(seeded on the tag, so a cover swap re-keys it) whenever a tag is
present but no blurhash has been computed yet. Known-absent artwork
(ImageAbsent) is unaffected: it still emits neither tag nor blurhash,
since GetOrPlaceholder would otherwise pin a shared placeholder under a
distinct cache key for a year.

* fix(jellyfin): avoid computing a synthetic blurhash when a real one exists

cmp.Or evaluates both arguments before choosing between them, so
blurhash.Synthetic ran (and was discarded) on every call even when
img.BlurHash was already set. That's the common case in production:
artwork_repository.go populates BlurHash from persisted values once a
scan resolves it, so a healthy library paid the synthesis cost (xxh3
hashing, HSL conversion, image alloc, DCT encode) on every mapped item
for a value it never used. Branch on emptiness first instead.

* feat(jellyfin): tint a pending track's placeholder with its album's colour

primaryImage never reaches the embeddedArtPending branch of
SongToBaseItem, since there is no resolved image yet to feed it. Seed
the synthetic blurhash on mf.ID (so the value stays unique and the
client still issues the read-through request) but tint it with the
album's DominantColor, which is already hydrated on MediaFile at no
extra cost.

* style(artwork): trim synthetic blurhash comments to the budget

* docs(jellyfin): fix stale blurhash README bullet + two review nits

The "Blurhashes are synthetic" bullet under Known limitations described
dto/blurhash.go, which was deleted when the real core/artwork-computed
blurhash + synthetic-fallback pipeline landed; every claim in it was
false. Replaced it with an accurate paragraph in the Images section,
since the described behaviour is now the finished design, not a gap.

Also: fix a doc/body comment mismatch in blurhash.go (component counts
are 2..9, not 1..9), and deduplicate the inline DC-extraction logic in
synthetic_test.go by reusing the existing dcOf helper.

* refactor(artwork): slice the synthetic cell jitter on byte boundaries

The three perturbations came off one hash with mismatched masks and shifts
(0xFF at 0, 0x3F at 8, 0x3F at 14), so a reader had to do the arithmetic to
confirm the fields did not overlap. Only 20 of the 64 bits were in use either
way, so the narrower fields bought nothing.

Uniform byte slices at 0/8/16 are non-overlapping by inspection and give each
field the full 8 bits. Both 1,000,000-seed collision specs still measure
1,000,000 distinct values. Also drops the local `n` alias, which was a second
name for synthComponents inside a 15-line function.

* docs(jellyfin): fix the blurhash paragraph's opening sentence

It opened with "follow the same principle", pointing back at the preceding
paragraph on admin-context artwork resolution — an unrelated subject, so the
reader looks for a connection that is not there.

* fix(artwork): render the synthetic grid larger than its component count

The 3x3 cell grid was handed straight to the encoder as a 3x3 image, so the
source had exactly as many samples as basis functions. Blurhash normalises its
coefficients by 1/(w*h) and 2/(w*h), which assumes many samples per component,
so the AC terms came out far too large. At the bottom-right corner the x and y
bases are both [1, -0.5, -0.5], everything lines up negative, and the result
clamped to black — a dark blob on every synthetic placeholder.

Rendering the same nine colours bilinearly at 8x8 first removes it: measured
over three seeds, the darkest corner goes from 13 to 74 and the darkest pixel
from 1 to 63. 8px is the smallest size that clears the artefact; 12 and 16 are
visually indistinguishable and cost 1.7x and 2.7x more.

The interpolation is hand-rolled rather than x/image's scaler, which allocated
528 times per call against 14 for this. Both 1,000,000-seed collision specs
still measure 1,000,000 distinct values.

* refactor(artwork): tidy the synthetic upscale helpers

cellWeight nudged its upper bound with a 1e-9 epsilon so int() could never
land on the last cell. Clamping the coordinate and then the index says the
same thing without a magic constant, and makes the clamp-don't-extrapolate
intent explicit — edge pixels map outside the cell centres, so the fraction
would otherwise run past 1.

The grid type is spelled once as colorGrid rather than repeated in the local
and the upscale signature, and encodeAt's doc now states the source-size
contract that Synthetic depends on, so the next caller sees it at the
function rather than only in synthetic.go.

Output is unchanged: all seven sample hashes match byte for byte.

* perf(artwork): make the synthetic upscale separable

Both axes are square and constant-sized, so the per-pixel cell index and
weight were the same 8 values recomputed 64 times per call. They are now
built once by sync.OnceValue, matching the srgbToLinearTable pattern.

The interpolation is also separable: stretching each of the 3 grid rows
horizontally once and then blending rows vertically does 264 lerps where
the per-pixel form did 576.

upscale drops from 347ns to 260ns, Synthetic from 1780ns to 1669ns. Output
is byte-identical across all seven sample hashes — same operations in the
same order, only hoisted.

* refactor(artwork): let a caller supply the cosine basis

encodeAt built its cosine tables inline, so Synthetic rebuilt bit-identical
ones on every call — its shape is always 3 components over 8 pixels. Splitting
the table construction into cosBasis and the encoder proper into encodePixels
lets Synthetic build the basis once via sync.OnceValue, and leaves encodeAt's
signature and behaviour untouched.

Synthetic drops from 14 allocations to 6 (1669ns to 1508ns). The time saving
is small and this path only runs while artwork is still unresolved; the
allocation cut is the point, alongside a shorter encodeAt.

Every hash is unchanged: nine real Encode outputs spanning square, 10x200,
200x10, 1x50 and a real JPEG, plus all seven synthetic samples, all byte for
byte identical before and after.

feat(artwork): make the artwork image size cap configurable (#5931)
* feat(artwork): make the artwork image size cap configurable

Replace the hardcoded 20MB cap on resolved image reads with a new
MaxImageSize config option. Load floors it at MaxImageUploadSize so an
accepted upload can never be too large for the resolver to read back.

* fix(conf): reject zero-valued byte-size options at startup

ParseBytes accepts "0", but parseSize silently substitutes the default
for it, so the accepted config would differ from the effective limit.

* fix(conf): reject byte-size options that overflow int64

A raw value above math.MaxInt64 parses as a valid uint64 but wraps to a
negative int64 in parseSize, giving readCapped a non-positive LimitReader
bound so every artwork read comes back empty.

c4126fa674 fix(jellyfin): emit SortName for artists and albums, honoring PreferSortTags
Finamp's A-Z fast scroll re-derives each item's sort key client-side from
SortName, paging until it reaches the tapped letter. We only emitted SortName
for songs, so Finamp fell back to reconstructing a key from the display name,
which diverges from the order_* key the list is actually sorted by (curly
quotes, non-English articles). The scan then believed it had passed the
letter and scrolled back to the top instead of loading further pages.

Emit SortName for artists and albums using the same key the persistence
layer sorts by, via a sortName helper that mirrors Subsonic's PreferSortTags
handling: order_* names by default, sort tags when the config is enabled.
The song mapper now honors the config too, instead of always preferring the
sort tag. Also parse Fields in the /Artists* handlers, which ignored the
parameter entirely, so no field-gated data could ever be returned there.

perf(genre): index genre filtering via join tables across all APIs (#5940)
Filtering by genre scanned every media_file/album row and JSON-parsed its
`tags` column (a per-row json_tree(tags) EXISTS) with no usable index, so
Finamp's genre screen took 1.9-6.5s per tap against a ~97k-track library.
Album and album-artist genre queries had the same unindexed shape.

Add normalized media_file_tags and album_tags join tables (genre only for
now, via an indexedTagNames allowlist), populated by a new updateTags in
Put (mirroring updateParticipants) and backfilled in the migration. Genre
filtering across the Jellyfin, Subsonic and native APIs now runs as an
index-backed semi-join through shared TagIDSemiJoin/TagNameSemiJoin helpers
instead of a full scan. On a copy of the production DB the per-request cost
for a typical genre drops from ~330ms to sub-millisecond, adding ~10MB.

8e0ff1a235 fix(jellyfin): resolve genre id as a MusicGenre item
The Jellyfin /Items/{id} endpoint resolved albums, artists, songs and
playlists by id but not genres, so a genre id returned 404. Finamp's
genre "See all" fetches the genre as the track list's parent item, and
that 404 crashed its screen to a blank page after the tracks flashed in.

Add a Genre lookup to resolveItemByID (backed by a new GenreRepository.Get)
so a genre id returns its MusicGenre BaseItemDto, matching real Jellyfin.
