album page: the record gets a page of its own, under the same glass bar
The album page was a back link, a 150px cover and a list of titles — a
placeholder beside the artist page it is reached from. It is now built from the
same parts: the frosted glass header, a hero carrying the record's own art and
palette, the play-count bars, and the edition cards.
**The glass bar is the artist page's, not a copy of it.** Same 46px, same
rgba(20,20,24,0.28) over blur(12px) saturate(1.7), same sticky top:-24px with
the -24/-28/-22 bleed that spans the pane and leaves zero flow height. It is
meant to be the header every page navigates by, so it had to be the same
object rather than something that resembles it.
It gains one thing here: the record's cover, name and a play button fade into
the bar once the title itself has gone under it, so the bar always says where
you are. That watches the TITLE, not the identity block — watching the block
meant waiting for the artwork to clear too, about 240px of scroll on a page
that only has 199px of it, so it would never have fired on a ten-track album.
**The hero is one proportional block.** `--cover-scale` sizes the artwork
(282px) and everything beside it is `em` off that one root, so type, gaps, the
artist portrait, the pills and the stat divider all move by the same factor.
Two earlier attempts are worth naming because they both looked wrong:
- damping the type (0.6 + 0.4·s) made the words visibly lag the artwork;
- `space-between` filled the height but opened the gaps faster than the type
grew, so the block came apart as it got bigger.
The gap is 1.8em, which is what the five rows need to fill the cover exactly,
and being an em it keeps that fit at any size. Measured live: the label's top
and the buttons' bottom both sit 0px from the artwork's edges. The hero's own
height derives from the artwork (`--cover + 68px`), so the 24px under the glass
bar holds at every scale instead of being a second number that drifts.
**Editions come from src/lib/editions.js — the artist page's own grouping.**
`releaseFamilies`, `editionBaseTitle`, `isEdition` and `editionLabel` moved out
of CatalogArtist.svelte (143 lines deleted there, not duplicated) so both pages
fold a record's pressings the same way. Two implementations would have drifted
invisibly: each page would show a plausible edition list and disagree about
which pressings are one album.
The album payload has no siblings, so the family is rebuilt from the artist's
discography. It reads the FULL page rather than the overview — the overview is
the artist page's first-paint subset and both dropped the anniversary edition
and carried no track counts, so the rows read "1994" where the discography
reads "1994 · 50 tracks". Cached per artist, and already warm whenever this
page was reached from theirs. Live, the Blue Album now lists Original 10 /
Deluxe 24 / Anniversary Super Deluxe 50, matching the discography exactly.
One deliberate narrowing: the artist page buckets releases by category before
grouping, and that categorisation leans on page state this view does not load
(harvested description hints, MusicBrainz type hints). So a sibling is accepted
only when the backend LINKED it (`edition_group`, a verified ordered core-track
match) or it declares the same record type. That can only ever show fewer
editions than the discography, never promote a separate live album or
compilation into this record's edition list.
**Switching edition is a swap, not a navigation.** `openCatalogAlbum` grew a
`keepCurrent` option that holds the page already on screen instead of clearing
to the loading state; the incoming cover is decoded before the swap so the
artwork crossfades rather than blinking out; and the parts are re-dealt on the
same clock as the expander — 400ms quintOut, 7px lift, banner → cover → kind →
title → meta → stats → actions → tracklist → description → editions → credits.
Polled at 16ms through a swap: 0 blank frames. The blurred banner fades without
lifting, because sliding a 42px blur reads as a wobble, and every part animates
to its OWN resting opacity — the banner rests at 0.62 and animating it to 1
would have run the colour wash half again too bright for the whole swap. A
failed load under `keepCurrent` clears anyway, so a dead edition surfaces the
error instead of looking like the click did nothing.
**The byline shows the artist, not the album cover again.** The album payload
carries the artist's NAME and nothing else, so `resolveArtistSeedByName` reads
and fills the same cache `openArtistByName` uses: the click that navigates
there has usually already paid for it, in-flight lookups are deduped so the
page and its own back button cannot fire the same search twice, and a transport
failure stays retryable rather than being cached as "no artist". A neutral dot
holds the space until it lands, so the line never reflows.
Shuffle and Preview join Play and Save. Shuffle is an action on this record,
not a toggle — it always turns shuffle on rather than flipping a global and
silently starting the album in order — and stays lit while it is on so that
state is visible from here. Preview opens the same modal the artist page does;
`buildAlbumManifest` already existed in the preview layer with no caller, which
is what this surface was for. It reports partial availability the same way, and
the manifest is a snapshot so an edition swap cannot rewrite an open session.
Also: plays bars, the whole-track/listener totals, the editorial description
and a released/label line, all off data `catalog_album` was already returning
and the page was throwing away. The plays column hides below three tracks — a
bar measured against itself is not a comparison, and on a single it read as a
rating. Track counts are pluralised, so a single says "1 track".
No add-to-playlist button. `add_to_playlist` requires a file path per track, so
a catalog album can only be added once it is in the library; that is a playlist
decision, not something to slip in behind an icon.
150 Rust tests and 85 JS tests pass.

loudness: a prefix may lower a track's volume but never raise it
A track that opens on a lone guitar and swells into a full chorus played that
chorus far too loud. The head of an unmeasured stream was being treated as a
measurement of the whole song: at ten decoded seconds the analyzer's running
integrated value became the gain for the entire play, and a quiet opening
under-reads, so the estimator asked to turn the track UP and the song then
arrived at its real level already amplified. `PRELIM_MAX_BOOST_DB = 3.0`
bounded that mistake without preventing it, and the three decibels land
exactly on the loudest part of the song.
Measured on the 69 complete tracks in the stream cache, with the app's own
meter and its own gain policy, comparing what the 10 s head asks for against
what the finished track asks for:
prefix error in applied gain (+ = plays too loud)
1s min -4.6 p50 +7.7 p95 +15.8 max +17.0 too loud: 61/69
3s min -0.9 p50 +5.2 p95 +15.7 max +17.0 too loud: 57/69
10s min -1.5 p50 +2.9 p95 +14.6 max +17.0 too loud: 57/69
The head is wrong in one direction and wrong by a lot. So it may only ever
cut: `PRELIM_MAX_BOOST_DB` is 0.0, and a boost has to be earned by a
measurement that reached the end of the media.
**Cuts-only rather than the flat unity the design called for.** The design
doc's stated first-release policy is that an unknown partial stream stays at
0 dB, with cuts-only left as a later experiment. Measured against this
corpus, unity is the worse of the two in the direction being complained
about — first-play loudness relative to the −14 LUFS target:
unity (doc's policy) p50 +5.6 p95 +8.5 LOUDEST +10.6 >3dB over: 57/69
cuts-only p50 +2.7 p95 +6.7 LOUDEST +8.0 >3dB over: 31/69
old policy, capped +3 p50 +2.7 p95 +9.5 LOUDEST +11.0 >3dB over: 32/69
verified (later plays) p50 +0.0 p95 +0.0 LOUDEST +0.0 >3dB over: 0/69
Unity would hand back the cut that loud-opening tracks already get today:
"Spread Eagle Cross the Block" reads −3.4 LUFS over its head and −3.4 over
the whole track, and is cut 10.6 dB — under unity its first play would be
10.6 dB louder than it is now, which is the reported bug wearing a different
hat. The tail risk that argues for unity is a loud opening over a quiet body,
where the head over-cuts; on this corpus that case tops out at 1.5 dB (My
Bloody Valentine, "Only Shallow": head −11.3, track −12.8) and the existing
−15 dB floor bounds it. The corpus is one library and contains no fortissimo
opening over a pianissimo body, so it bounds the error it can see, not the
error that exists. Revisit if a cut ever sounds wrong.
**Only a whole programme may be cached.** `analyze_loudness` returned the
same `Option<(f64, f32)>` whether it reached the end of the media or the
bytes simply stopped, and `on_track_started` stored it either way — with a
comment saying it was valid "whatever happened to this one". It is not:
`GrowingFile::read` maps an aborted transfer to `Ok(0)`, a graceful EOF, so
skipping a song mid-download recorded whatever its intro measured, filed
under the full declared remote size, and every later play boosted the whole
track off it by up to `MAX_GAIN_DB` — the same bug as above, but permanent
and three times larger. It now returns `Analysis::Complete | Incomplete`,
where completeness is decided by asking the transfer how it ended
(`StreamProgress::terminal`) rather than by asking a reader that cannot tell,
and only `Complete` reaches the cache, the preload boundary gain, or a
preview clip's gain.
That path was reachable but had not fired. Re-measuring every cached track
against its stored value found no disagreement, and of the ten interrupted
transfers still sitting in the stream cache, none had left a loudness entry
at all — the analyzer normally wins its race with the download and either
finishes properly or is cancelled before the abort reaches it. So the
existing cache is not quarantined and not wiped: of 141 entries only 6 ask
for any boost above 0.5 dB, four of those are present on disk and verified
correct by a fresh scan, and the other two ask +1.4 and +1.0 dB. Discarding
141 good measurements to protect against a hazard that measurement says is
not there would cost more than it saves, and any record that is wrong is
overwritten by the next complete play.
**The audible start is now bounded from the play request.** Both existing
windows are measured from the first measurement, and a track opening below
the −70 LUFS gate never produces one, so silence or a long fade-in held
playback until the analyzer found audio loud enough to measure — on a slow
stream, a wait with no upper bound. `PRELIM_HARD_DEADLINE` (2.5 s) releases
the start regardless, at the best cut the evidence so far justifies. This
costs nothing: the player blocks on the growing file anyway, so releasing
early hands it the start rather than making it wait. Verified against a
223 MB FLAC whose first bytes had not arrived at 2.2 s.
**Stop now cancels the measurement window.** Found while verifying the
deadline: `player_control("stop")` never touched the loudness generation, so
a track stopped during its window could be handed its deferred start a moment
later and begin playing after the user had stopped it. Pre-existing, but the
deadline makes it reliably reachable, so `on_playback_stopped` orphans the
analyzer and the held start.
Not done, and deliberately: true peak and the −1.0 dBTP ceiling (the meter
measures sample peak, so `PEAK_CEILING` is still 0.98 sample), the versioned
measurement cache with real asset identity, ReplayGain/R128 metadata, the
output limiter, track-bound gapless gain, and queue-ahead analysis. Those are
later phases and none of them is needed to stop the over-boost.
Verified live, driving the running app:
quiet intro, first play head −27.4 LUFS → 0.0 dB (was +3.0 dB)
quiet intro, second play track −6.0 LUFS → −8.01 dB from the cache
loud intro, first play head −3.4 LUFS → −10.64 dB cut still applied
Soulseek stream, cold head −18.8 LUFS → 0.0 dB, track measured −9.0
and cached for the next play without touching
the gain in force
stop mid-window no start behind the stop, no cache entry written
The debug overlay now names what the gain was decided from — "whole-track
measurement (cache)", "prefix (cut only)", "unity (nothing measured yet)" —
because the difference is invisible in the numbers alone, which is how this
went unnoticed. Settings no longer claims "boosts never clip", which nothing
in the output path enforces; it describes the actual guarantee instead. The
module header's claims that the gain glides mid-track and that previews are
not normalized were both false and are gone.

popular: let Last.fm decide what is popular, and Deezer only how to play it
Popular took Deezer's `/top` fifty and re-sorted it by scrobbles, so the LIST
could never be better than Deezer's catalogue. For most artists that is
invisible — measured against Last.fm's own top ten, Queen, Radiohead, Weezer,
Green Day, Fleetwood Mac and Tame Impala agreed on 56 of 60 rows. For an artist
Deezer carries badly it is the whole page. Deezer has no Loveless at all: 8 of
My Bloody Valentine's Last.fm top ten are absent from its catalogue outright,
so Popular filled up with b-sides, a compilation cut and a soundtrack cut, and
"When You Sleep" — the song with 1.28M listeners, more than any other they
recorded — could not appear at any position.
So Last.fm's ranking IS the list now, and each entry is resolved in preference
order: a Deezer track of the same `track_title_identity` when one exists, since
that brings a real album, cover, preview and duration and stays eligible for
attribution; otherwise a row built from the MusicBrainz recording, which
supplies the record it belongs to and the track length. Anything neither
provider can place is dropped, and Deezer rows Last.fm never ranked still
backfill from underneath so a thin Last.fm artist keeps a full list.
A synthesized row has no 30-second preview and that is the whole cost, because
playback never needed one: streaming resolves over Soulseek by artist and
title, and the Deezer id only ever marked the now-playing row. The previews
button already reports partial availability, so it reads "7 of 20 available"
rather than pretending.
Their albums come from ONE request. `release?artist={mbid}&inc=recordings+
release-groups` returns every release WITH its tracklist and names the work each
pressing belongs to — measured on My Bloody Valentine, 208 KB covering 64
releases that fold to 27 works. The alternative was a lookup per supplemented
album behind the 1 req/s gate. Only the full page pays for it; the overview
still just orders Deezer's pool and is replaced wholesale a moment later.
**And a relabel for songs whose record Deezer does not sell.**
`apply_original_album_attribution` can only move a track onto another DEEZER
album, because it swaps the row onto that album's real track — so when the
original is missing from Deezer entirely there is nothing to swap to and the row
keeps the pressing Deezer licensed, which is exactly the kind of record the rule
exists to remove. Deezer carries precisely two Loveless songs, "Only Shallow" on
the compilation *Amateur* and "Sometimes" on the *Lost In Translation*
soundtrack, so those two sat under a compilation and a soundtrack while the
eighteen tracks Deezer does NOT carry already showed Loveless.
That pass is a relabel, not a swap: album, album_id and cover follow
MusicBrainz while id, preview and duration stay on the Deezer pressing, which is
still the playable one. It may only take a row AWAY from a record that is not a
studio album, or it would overrule a correct attribution and trade a real album
card for a synthetic id with no card behind it — verified, Queen's "Bohemian
Rhapsody" stays on *A Night At The Opera* and the pass reports 0 relabelled for
Queen and Radiohead.
Mixtape/Street counts as a studio record for this, for the same reason it earns
its own tab: excluding it left "Guillotine" attributed to the SINGLE named after
it rather than to Exmilitary, which is the album it opens. Every other secondary
type still disqualifies.
POPULAR_KEEP 10 → 20, and the frontend's own `slice(0, 10)` is gone rather than
raised to match. There were two caps for one number and they disagreed the
moment either moved; the backend owns it now.
Measured live: My Bloody Valentine's Popular is Last.fm's ranking exactly —
When You Sleep, Only Shallow, Sometimes, Loomer, To Here Knows When, Soon,
Touched — all twenty on Loveless or Isn't Anything. Queen gains "We Will Rock
You" on *News of the World*, which the Deezer-pool list omitted because Deezer
sells it only as a Movie Mix. Death Grips' "Guillotine" moves to Exmilitary.
75 Rust tests and 85 JS tests pass.
Known, and older than this change: Radiohead's "No Surprises", "Karma Police"
and "Let Down" attribute to *OK Computer OKNOTOK 1997 2017* rather than *OK
Computer*. Deezer carries both and dates BOTH 1997-05-21, so the rule's date
tiebreak cannot separate them and the 23-track reissue wins; `is_edition_title`
does not recognise "OKNOTOK 1997 2017" as an edition marker. The relabel pass
reports 0 for Radiohead, so this is the existing attribution rule, not the new
one.

discography: give mixtapes a tab, and stop the provider spelling it twice
Death Grips' "Exmilitary" was missing from the app entirely. Deezer never
carried it, and MusicBrainz has it but types the release group Mixtape/Street,
which the studio-album supplement excluded along with every other secondary
type. The same exclusion hid Chance the Rapper's "Acid Rap" and "Coloring
Book" — records that outscrobble everything he has released as an album.
They cannot simply join Albums. MusicBrainz files 118 Mixtape/Street groups for
Gucci Mane and 51 for Lil Wayne, which buries a 15-record discography, and no
significance gate separates the canon from the ephemera: measured on Last.fm,
Exmilitary sits at 19% of Death Grips' biggest record while Gucci Mane's
"Chicken Talk" sits at 20% of his. The two are indistinguishable by weight
because both are real. So the answer is filing, not filtering — a tab of their
own, where volume costs nothing and nothing has to be hidden. It sits beside
Albums rather than down with the archival tabs because for the artists who have
any, the mixtape is usually the canon. Empty tabs are already dropped, so
Queen and Radiohead never see it.
A SEPARATE query rather than a relaxed filter, and the page cap is the reason.
MusicBrainz returns 100 items, and asking one query for both — via
`-secondarytype:live AND -secondarytype:compilation AND …`, the only form its
Lucene actually honours, since a bare
`(-secondarytype:* OR secondarytype:"Mixtape/Street")` returns either nothing
or mixtapes only — came back with Gucci Mane's 87 mixtapes and just 13 of his
15 studio albums. The mixtapes ate the page and pushed two real records off it.
Split, the album supplement is byte-for-byte what it was, and the cost is one
request on the DEFERRED identity pass, disk cached for a day like every other
MusicBrainz call.
The tab then exposed a dedup hole that had been there all along.
`normText` DELETES bracket contents, which is correct for the peer file
matching it was written for and wrong for release identity. MusicBrainz writes
a qualifier after a colon where Deezer puts it in parentheses, so
"World War 3 (Lean)" reduced to "worldwar3" while MB's "World War 3: Lean"
reduced to "worldwar3lean". They could never collide, so the supplement
injected a second card for a record already on the page — and with mixtapes now
filed apart, the same work appeared in Albums AND Mixtapes. Ten such pairs on
Gucci Mane, among them "Wilt Chamberlain (Pt. 5)" / "Wilt Chamberlain, Part
Five", "Bird Flu 2" / "Bird Flu, Part Two" and "Trap House 4" / "Trap House
Four".
The identity merge gets its own key, which keeps the qualifier and folds the
three things the providers genuinely disagree about: the separator, the words
introducing a number, and whether that number is a digit, a word or a roman
numeral. Single-letter romans are deliberately NOT folded — "X", "V" and "I"
are real album titles and reading them as 10, 5 and 1 would merge unrelated
records.
And a matched mixtape contributes its TYPE, not a card. The Deezer row keeps
the slot because it is the playable one — real album id, real tracklist — and
MusicBrainz's verdict re-files it, exactly as `type_hints` already re-files a
mislabelled compilation. That is what moves "World War 3 (Lean)" out of Albums
instead of leaving one copy in each tab. It is also why Gucci Mane's Albums
count falls 146 -> 73: those rows were ALREADY being swallowed by the old
title check and left sitting in Albums untyped, so this does not hide them, it
finally classifies them.
Every row sharing a key adopts together, not just the first. A provider
sometimes carries one record twice under its own spellings ("Brick Factory 2"
beside "Brick Factory, Vol. 2"); typing one of them and not the other put one
copy in Mixtapes and left the other in Albums, which is a worse page than
leaving both alone.
Measured live: Gucci Mane 252 -> 241 rows with cross-tab duplicates 10 -> 0,
Death Grips one mixtape and it is Exmilitary, Queen and Radiohead unchanged
with no Mixtapes tab rendered. 75 Rust tests and 85 JS tests pass.
Still open, and older than this change: Deezer carries "Brick Factory 2" and
"Brick Factory, Vol. 2" as two rows, and "Trap House 3" beside "Trap House
III". This key would collapse them, but that means deleting a row the page
currently shows, which wants measuring across a range of artists first.

artist page: open an album in place, and show what the numbers are worth
The discography grid gains an expander: click a record and it opens between the rows, with a rail carrying the art, the totals and the editions, and a track list beside it. Three strands landed on this file across as many sessions and they share the same DOM -- the row template the plays column widens is the one the expander draws, and the keying that attribution needs is what makes the cover crossfade possible -- so they arrive together. **Keeping the grid still while a panel grows inside it.** An expander opening mid-grid moves every row below it, and the naive version fights its own animation: the reserve is measured against a layout that is still collapsing. So each expander other than the one being kept is treated as mid-outro and discounted from the measurement, the grid's `min-height` glides to the new reserve rather than snapping, and a same-row switch keeps BOTH panels alive -- `panelLeave` takes the outgoing one out of flow so the two overlap instead of stacking, and the stage eases between their heights so the box never collapses to nothing on the way. `.xp-stage` exists to be the containing block for that. **The loading state only exists if the load is slow.** A warm open resolves in tens of milliseconds and used to flash a line of text on its way past, so nothing renders until the load has outlasted a 250ms grace -- and when it does render it is placeholder rows drawn in the track grid's exact geometry, so the real list replaces them in place rather than reflowing. **Cover tier follows DPR, not window size.** The rail art is a FIXED 209px -- the rail column is 250px regardless of monitor -- so a 4K display does not make the box bigger; only device pixel ratio does. 209px needs 418 device pixels at DPR 2, which the 500 rendition covers, and side by side at DPR 2 the 500 and 1000 sources are indistinguishable at actual size. At DPR 3 the 500 is visibly soft. So 500 below that line and 1000 above it, rather than paying 3.6x the bytes (148KB -> 501KB per cover) on every display to fix the top one. Coverart Archive has no 1000 rendition; its next step is 1200. **Popular rows are keyed on `origin_track_id ?? id`.** This is what lets the backend hand a row its original album without destroying it: the corrected row is REUSED rather than torn down and rebuilt, which keeps its save state and is the whole reason the cover can crossfade instead of popping. `nowPlayingTrack` matches either id, so a track that is playing stays marked as playing across the correction. The crossfade itself needs the proxied art SYNCHRONOUSLY -- one microtask is still a frame with the raw CDN url in `src`, which is a network request for a file already held -- hence `peekCatalogArt`, which returns the resolved data URL or null and never a promise. The replay recipe goes to v4 for the same reason it went to v3: a v3 replay carries Deezer's licensed attribution on every popular row -- Bohemian Rhapsody on the 2018 movie soundtrack, wearing that poster -- and painting a known-wrong album name instantly is worse than one ordinary load. **Plays, as a heat block rather than a bare number.** Bar length and colour both scale with the count, tinted with the OPEN album's accent so the column reads as this record's own. The header and the rows share one grid template, so the columns line up whether or not Last.fm knew the record -- and when it knew nothing the whole column, header included, stays out of the layout entirely. An unknown track is a dash, never a zero. Album totals sit between the meta line and the Play row, badged when they were summed from the tracklist because the provider's own figure could not cover its biggest track. The listener count in the Popular list needed the row wider: break-even was 833px for the column plus its gap, up from 760px, and the rest is air, so title and album each end up ~38px wider than before rather than narrower. That column is muted and deliberately NOT accent -- the row already spends the accent on `.now`, and a coloured column on every row drowns the one that means "playing". |

cover logo: fit the traced outline to lines and curves, not a decimated polyline
traceToSvg emitted polylines. Marching squares produced a sub-pixel contour and RDP threw points away at eps=0.2 until what was left could be joined with "L", so a curve arrived as facets and a straight edge arrived as a ripple. The ripple is the one that reads at hero size, and the reason is a measurement rather than a matter of taste: on these masks a mathematically straight edge still wanders through the alpha field -- print grain, JPEG ringing, and the shadow un-blend being a two-colour model of a soft gradient. Measured over the acceptance set that wander peaks around 0.15-0.3px across a 40px run on a clean source, so eps=0.2 sits BELOW the noise floor and RDP was faithfully reproducing the grain. Tightening it makes that worse; loosening it far enough to clear the noise starts cutting real curvature. Fitting cubics under a looser tolerance is the obvious answer and it does not work. Schneider pins each segment's endpoints to actual sample points, so every join inherits that one point's share of the noise; measured, the straight edges came out no better than RDP left them (ripple 0.56 -> 0.64px). Raising the tolerance does not help, because the endpoints are pinned regardless. What removes the noise is fitting a LINE to the whole run and throwing the samples away. A total-least-squares line over a few hundred points has an error of noise/sqrt(n) -- hundredths of a pixel, not tenths. Vertices then become the INTERSECTIONS of neighbouring primitives rather than sample points, which has a second payoff: the trace blur rounds every real corner into a small arc, and intersecting the two adjacent lines puts the sharp corner back. So the pass is corners, cut at them, maximal straight runs, cubics for the gaps, then resolve the joints. Prefix moments make a line fit over any index range O(1), which is what keeps growing a run near-linear rather than quadratic on exactly the long straight edges it exists for. Three things a straightness test cannot decide on its own, each found by looking at where the lines actually landed rather than at an aggregate. - A residual test admits CHORDS OF A BOWL. On a circle of radius R a chord of arc length L departs from its own best-fit line by only about 0.3 L^2/(8R), so at any tolerance loose enough to absorb grain a big enough bowl accepts straight pieces -- which is how the counters of Hot Toddy's O's came out as polygons, 73% of that outline drawn straight. The evidence lies OUTSIDE the run: fit a circle to a window extended past both ends, and if that window is a clean arc whose sagitta across the run exceeds arcSagitta, the run is a chord. On a loop with no corners the window has to WRAP, because the seam goes at the tightest bend and clipping there would exempt the one place that most needs the test. - The ends OVERRUN into the bend. RMS is an average, so a run absorbs the first few px of a curve and still passes; the line then chords the start of the bend and the cubic is left too little room, which is the kink at a stem-to-shoulder junction. Each end is trimmed back to where a window-fitted direction still agrees with the run's line. It has to be a WINDOW fit -- a point tangent over a few px of grainy edge carries several degrees of noise by itself and trims at random, which put the ripple back up from 0.19 to 0.48px -- and the threshold has to rise with the run's own measured noise, or it means something different on a clean print than on a rough one. An end sitting on a detected corner is not trimmed: the contour runs straight into a corner by definition, and that direction is what the corner is reconstructed from. - Extrapolating to an intersection is unbounded. As a wedge closes the legitimate apex offset grows without limit, and so does the error in it, because two nearly anti-parallel lines cross at a point a fraction of a degree can move a long way. The inside of Mildlife's M reconstructed 11px past its real apex and cut a white spike into the letterform. The shift is now bounded by what the rounding can explain -- r*(1/sin(theta/2) - 1) for a wedge of interior angle theta -- and CLAMPED rather than discarded, since a corner pulled back to the limit is still sharper than the blurred contour whereas falling back to the contour point throws the reconstruction away. Corner sharpness measures identical anywhere from a 2px to a 12px ceiling, so the ceiling costs nothing and only removes the failure. Acceptance over the eight-artist set, against the polyline it replaces: ripple on edges that are straight beyond argument 0.228 -> 0.015px, with 637 -> 8 interior vertices spent on them; curvature reversals 6.7 -> 1.5 per 100px; corner turn-arc 8.03 -> 5.48px; 1557 -> 276 segments and 21.2 -> 9.5KB of path. Hot Toddy, the mark whose terminals must not soften, goes 3.32 -> 0.25px with 0 of 34 corners softened. Men I Trust improves least (9.7 -> 6.1 reversals) because its print genuinely is crenellated and the path tracks it. Cost is 18-33ms in the app's own engine, against contours() at 90-140ms. The old polyline remains behind traceToSvg's `fit: false` for A/B. |

cover logo: supersample the winner, and scale to the target not past it
Five changes to the mask the tracer receives, plus the diagnostic needed to tell them apart. The alpha ramp's bottom now scales with the measured ink distance instead of sitting at a fixed 46. On a faint mark that constant ate the outer half of every edge gradient -- Wand's "Machine Man / M.E." inks at distance 97, so the pixel carrying ~20% coverage was forced fully transparent and the boundary quantised to whole source pixels. The finished alpha is then rescaled so the glyph body reaches opacity, bounded at 4x; narrowing the ramp onto the ink was tried instead and let paper grain bite the edges. A BLIND OCR read (zero lines, not "no match") retries once at 512px. Windows OCR is scale-sensitive on large display type and reads that cover at 512 and at no other size; gating on blindness rather than on no-match kept a 21-artist regeneration at 1m47s where the looser gate took ~6min. The winning cover is re-cut with the crop resampled up BEFORE the alpha ramp, so smoothstep evaluates interpolated colour and places the edge between source pixels. Selection still runs at native scale: extract_wordmark feeds MIN_MARK_H and the aa/coverage/bleed score, so supersampling during scoring changes which cover wins. That scale is fractional. A floored integer factor is 1 for every crop wider than half the target, so at 2400 a crop of 1201px was supersampled by nothing at all while 1200px got 2x -- and the covers on the wrong side of that cliff are the large printed wordmarks, where the staircase was worst. Measured over eight artists, Hot Toddy's zigzag share fell 0.312 -> 0.048 and Crazy P's 0.220 -> 0.021, with every other artist unchanged. 2400 itself is confirmed by sweeping 1200/3600/4800: past 2400 the mask overshoots the tracer's raster so the browser downscales what Rust just built, every shape measure goes flat and the data URL doubles. catalog_cover_logo_debug reports the rejection reason and the mask itself, and its cover cap follows COVER_LOGO_MAX_COVERS instead of undercutting it at 14 -- where it hid exactly the covers production relies on. The artist page also re-runs the logo pass when ownership changes the covers on offer; that pass races the identity merge and had been reading the unfiltered list, which is how Wand wore a wordmark lifted from a co-tenant's single. |

release ownership: one Deezer id can be seven artists
There is exactly one Deezer artist called "Wand" (1213178) and it holds the LA psych band, a Brazilian funk MC, an Indonesian act, an Indian one, a 2020 house project and whoever released Hard Knox in 2009 — 46 of its 72 rows are somebody else's. Ranking search results cannot help (there is one candidate) and neither can credit role (every row is primary-credited to it). The Apple namesake filter that should have caught this switched itself off: APPLE_EXACT_ARTIST_CANDIDATE_LIMIT is 8 and Apple has TEN artists named Wand, so the candidate fetch failed closed and every catalogue came back empty. It fails closed for a good reason at page-load time — it picks the winner by overlap with the requested artist's own Deezer releases, which on a fused record are partly the co-tenants'. Circular evidence has to fail closed. So the answer is not to raise that cap but to stop asking the fused list. artist_release_ownership runs in the DEFERRED identity pass, where the linked MBID has already named the artist, and picks the Apple performer that reproduces THAT catalogue. Non-circular, so 20 candidates is safe. Evidence is MB release groups of every type, the verified Apple catalogue, and the label sets of both (MB at one sighting, Apple at two — Apple files two rafftheraff singles under the LA band). Pruning only runs where a row is provably carried by a different same-named Apple artist, so the gate opens on 4 of the 55 artists measured and stays shut on Wednesday's twenty namesakes, Jungle's sixteen and Roosevelt's fourteen. The same evidence repairs the opposite failure. The guest guard keeps an appears_on row only if MB credits it to the artist's own MBID, which assumes MB mirrors collaborations. It does for Watch the Throne, whose artist CREDIT names both. It does not when the collaboration is its own entity: VULTURES 1, VULTURES 2 and KIDS SEE GHOSTS appear nowhere in Ye's 315 release groups, and all three were being erased from his page. Apple's artistName credit, read as a list of principals, restores them without restoring guest spots — Estelle's "American Boy (feat. Kanye West)" is still hers. A fused record's PORTRAIT is wrong for the same reason its releases are: it is whichever co-tenant uploaded last, a real photograph of the wrong person, so deezerPortraitMissing cannot see it. The verdict is persisted, because the search dropdown is typed against per keystroke and can never afford the lookups that produced it. Its store is deliberately not in net-cache-v1 — prune_disk_cache deletes every json there by mtime, and a verdict is not a cached response. Measured live: Wand 72 -> 26, Hot Toddy 36 -> 16, Crazy P 68 -> 51, Turnover 30 -> 25, Kanye 50 -> 64; Weezer, Pond, Billy Cobb, JPEGMAFIA and Daft Punk untouched. The page's "wand." wordmark went with the co-tenants and should have: it was traced from the Indonesian single's cover. |

artist page: put the load status in the chip row it hands over to
The floating pill worked but sat in the wrong place and at the wrong scale: top right of the pane, far from the content it describes, 30px tall with 12px text against a row of 27px chips at 11.5px. The stat chips are gated on `!page.art_preview` -- they do not exist yet while the page resolves. So the status simply takes their slot and hands the row over when they arrive: same container, same `.chip` metrics, with only a spinning accent ring and a softer label colour of its own. Measured across the handover, the status chip and the first real chip occupy the identical box (x 230, y 1145, height 27), and neither the row top nor the play button moves. That also keeps the property the floating version was chosen for. Nothing reflows when the status goes, because it is the only thing in the row and the chips that replace it start at the same origin -- no absolute positioning, no z-index fight with the sticky .results-head, and no element parked outside the layout it belongs to. |

artist page: float the load status instead of shoving the page down
"Refining release details…" rendered as a paragraph in the content flow, above the action row. It cost about 32px of layout, so the play button and everything under it visibly jumped up the instant the page finished resolving -- a shift announcing nothing more than that a background stage had ended. It also read as debug output: 12px secondary text and a bullet, in a page that otherwise speaks in pills and chips. It is now an absolutely positioned pill at the pane's top-right with a spinning accent ring. Measured: the play button and the Popular heading sit at identical offsets whether it is showing or not, so appearing and resolving move nothing. Two placement constraints, both found the hard way: - It must NOT live in .fade-flow with the rest of the body. That carries a transform, so the pill would anchor to it rather than the page, and it sits inside the clipped .fade-frame, which would mask it. - z-index has to clear 40, not merely .scrollbody's 3. The sticky .results-head shares this top band, and at any lower value it paints straight over the pill -- which looks exactly like the pill failing to render, with no other symptom. .artist-page was already position:relative, so this introduces no new containing block into a scroll pipeline that is sensitive to exactly that. The pill is pointer-events:none since it is never a target, carries role="status" aria-live="polite" so the stage change is announced rather than silently repainted, and holds the spinner still under prefers-reduced-motion rather than dropping the only sign that work is happening. |

cover logo: fix the two ways artists silently lost their wordmark
Both regressions were invisible because the pipeline's failure mode is a shrug:
no logo, no error, fall back to plain text.
1. The dominance guard was resolution-dependent. It bins the crop into a coarse
16-cubed RGB histogram and rejects when the dominant colour holds under half
the pixels ("text over a photo"). A BIGGER source resolves more grain and
JPEG texture, which spreads pixels across bins and shrinks that share -- so
the identical crop of Alvvays' "Blue Rev" measures dominance 0.746 at 1000px
and 0.226 at 3000px. Once the upgrade path started supplying hi-res artwork,
covers that had segmented cleanly for months began failing a guard that had
not changed; its input grew. The histogram and guard now read a copy
normalised to the 1000px they were calibrated at, while the alpha ramp still
runs at full resolution -- which is the whole reason for fetching the larger
cover.
2. Only the top 14 covers were ever offered. The rank puts albums first and
penalises remix/mix/edit/live titles, but a prolific artist's wordmark is
often on exactly those: Poolside has 74 releases and SEVEN covers that OCR
reads as "POOLSIDE", every one of them outside a 14-cover window. The cap
goes to 40 on both sides (the frontend list must not undercut the backend's,
since whatever it trims the extractor can never see). This is free for
artists that hit early -- the locate loop stops at COVER_LOGO_MAX_HITS -- and
is paid once, then cached, by artists with no wordmark at all.
Recovered: Alvvays (nothing -> 871x173), Poolside (nothing -> 528x225),
Men I Trust, and Motor City Drum Ensemble now extracts too. Verified no
regression across the rest of the research roster: Camping in Alaska, Crazy P,
Folamour, Hot Toddy, Mildlife, Session Victim, Turnover, Knocked Loose,
Snail Mail, Spiritbox and Todd Terje all still extract at their previous sizes.

cover logo: keep the source's anti-aliasing, then trace it lightly
The wordmark segmentation mapped alpha with smoothstep(46, 120) over distance from the background colour. That ceiling is fixed, but the ink distance is not: white text on a black band sits at ~438, so every edge pixel brighter than about 27% grey saturated to fully opaque. A hard threshold wearing a smoothstep's clothing. Measured on Camping in Alaska's "Needlemouth" cover, the extracted mask's edges transitioned over 0.10px against the source's 0.88px -- nine times harder than the artwork it came from. The ramp's top now tracks the measured ink distance (95th percentile of distance-from-background, so it reads the glyph body rather than the brightest speck), with the old constant kept as a floor so low-contrast marks are untouched. Retained anti-aliasing on that cover goes from 10.4% of inked pixels to 22.2%, and the glyphs thin back toward the source instead of being dilated by the saturation. That unlocks the trace side, which is the visible half. The blur there was never a goal -- it exists to synthesise anti-aliasing a mask lacks, and it melts serif terminals into blobs. With real gradients in the alpha, the cover-logo branch drops from ~0.93px of blur to a 0.5px floor and from eps 0.5 to 0.2, at a 2400px raster instead of 1400. Lowering eps ALONE was tried and rejected: against the old near-binary mask it just captured the pixel staircase in finer detail. Camping in Alaska's traced path goes 900 -> ~2500 vertices with no staircasing, and the serif terminals keep their shape. Cost is 35ms -> 65ms of main-thread work, once per cover-derived logo at page load, not per frame. |

discography: drop guest appearances, but only where MusicBrainz can arbitrate
Deezer's /artist/{id}/albums returns records the artist merely contributed to,
alongside their own. Mid-Air Thief's page carried four Rooby Jeantal lo-fi EPs
that way -- his real discography is two albums.
This is not the namesake bug that was hardened in July. Every identity step here
is correct: MusicBrainz links the artist to Deezer 51082452, that is the id we
open, and the MB supplement injects both real albums. The leak is credit ROLE,
which is why an identity fix never touched it.
Deezer cannot answer it alone. Album details expose the primary artist, so a
guest spot is visible -- but every contributor is marked role "Main", so Kanye
West on "Watch the Throne" (primary artist JAY-Z) is byte-for-byte the same
shape as a guest EP. A "not primary, therefore drop" rule deletes a real album.
MusicBrainz separates them, because it credits a genuine collaboration under
BOTH artists: Kanye's own MBID returns "Watch the Throne", Mid-Air Thief's
returns only his two albums. So the backend only FLAGS (`appears_on`, set from
the details pass where the release's primary artist is finally visible) and the
frontend drops a flagged row at the identity merge only when MB answered for
this artist and does not credit the row. No MB albums means no arbiter and
every row is kept -- thin-coverage artists never silently lose real releases.
EPs now enter the album-details pass, which is what made this invisible: the
pass was album-only, and all four guest releases are typed "ep". They already
sort ahead of singles for the details cap.
Replay recipe bumped to v2: pages cached before this are stamped
identity_merged and would skip the pass that drops the rows.
Verified live -- Mid-Air Thief 6 albums -> 2 (무너지기/Crumbling, 공중도덕);
Kanye West keeps "Watch The Throne (Deluxe)", flagged appears_on but MB-credited,
with all 58 rows intact.

artist page: keep the album reveal's target reachable
Opening an album juddered: the page ran at the clicked row, then stopped dead just short of it. revealIntoView lifts the row to the banner line, which needs a pane-height of content beneath that row. Until the previous commit the pane's ~2000px of dead scroll always supplied it. With the range ending at the content, a row in the last screenful no longer has it, so the reveal eased toward a scrollTop the range could not hold and slammed into the clamp — measured on a 29-album artist: target 1846 against a max of 1594, 272px in a single frame, then 39 frames pinned, and the row parked 598px below the line instead of on it. Not a race with the expander either; it finishes growing at ~500ms and the target is still 252px out of reach. Reserve the row's own pane-height, the same way the grid already reserves one for the tab bar so a tab switch cannot clamp the scroll — extended to the open expander's row and released when it closes. - On the grid's min-height, because that is what moves this page: .scrollbody's height does not answer to padding at all (border-box against a fixed height — 0px, 200px and 600px of padding-bottom all measured the same 1787px box). - Reserved, not predicted. The expander's height is not the page's growth: the slack in this very reserve swallowed 435 of a 486px panel, so a 486px expander grew the page by 66. - Stood up synchronously by the reveal as well as by measureCols, which only recomputes off a ResizeObserver — that fires after the 420ms animation has already parked against the old clamp. - Released on the expander's destroy. measureCols cannot notice the panel leaving: the raised min-height is exactly what stops the grid's box from changing, so the observer sees nothing and the reserve would stick for the rest of the visit, leaving a screenful of empty page under the grid. - Re-measured across the settle after an open. What moves the target row is the card art this very click asked for; those images land over the following few hundred ms and rows above the row grow as they do (measured: the row sat 488px into the grid when the reveal read it, 555px once settled). Only the first open of a page pays this. - The reveal clamps its target regardless and idles on it for up to a second, so a corrected reserve still completes the travel instead of ending short. Verified on a 29-album artist and an 11-album one: every open lands the row at exactly the 280px line, first open of a fresh page included, with no direction reversals and no frames against the clamp. Frame timing improves on both — cold 13 frames over 16ms (worst 79.6) to 2 (worst 60.6, the album fetch and decode, which predates this), warm 2 (worst 18.4) to 0 (worst 9). The pane's scroll range still ends exactly at the content with no expander open, and returns to it on close. |

artist page: always open at the top
.content is the app's one scroll pane and it outlives the view swap, so its scrollTop was inherited by whatever loaded next: leave one artist 900px down their discography, open another, and you arrived 900px down the new one — mid-grid, hero already squeezed into the bar, with no hint the page had a top. Reset it on catalog.artistOpenSeq, a counter bumped once per openCatalogArtist call, rather than on the artist's id. The id cannot distinguish a re-open of the artist already on screen — clicking their name from Now Playing while parked deep in their own page, where nothing moved and the click read as dead — from no navigation at all. Nor can this key on the page object: the cold path replaces it stage by stage under the same id, which would haul a reader back to the top mid-read. The counter bumps once per open and never per stage. The bump sits after openCatalogArtist's invalid-id bail-out, so a request that never opens anything cannot scroll the page the reader is still on. Verified live: three artist-to-artist hops parked at 1222 each land at 0 and stay 0 through every cold stage; re-opening the artist already on screen from 1070 lands at 0; mounting from another view with the pane genuinely parked at 1500 mounts at 0; and a reader parked at 600 on the artist they are already on holds at 600 through six seconds of stage churn. |

artist page: end the pane's scroll at the content (clip the 300vh sheet out of the scroll range)
The pane could scroll ~850px (1971px at a tall window) past the last content pixel: at max scroll ZERO of 11 release rows were on screen, the whole viewport empty page. The sheet is 300vh of absolutely positioned decoration, and an abs-positioned descendant extends its scroller's scrollable overflow. .content's scrollHeight tracked the sheet's box — pin flow origin + the sheet's live translate + 300vh — instead of the page. Because that translate is scroll-driven, the range also breathed with scroll position and depended on scroll history: the same scrollTop measured 4167, 4329 and 4368 depending on the route taken. Hiding the sheet gave exactly 1797, the page plus the pane's padding-top. Wrap the sheet in a .sheetclip box with overflow: clip, sized to the pane's client box, so the sheet paints exactly the region the pane can show and contributes nothing to the scroll range. - The clip box is ABSOLUTE and the pin stays height: 0. Sizing the pin itself and cancelling with a negative margin-bottom leaves +24px behind — the margin collapses against the neighbouring height-0 pins and walks the hero zone from 24 to 48. Out of flow there is no margin to collapse, and the sticky constraint is untouched. - overflow-clip-margin is not an option for the sheet's 28px bleed: it re-expands the overflow region right back to 2440. The bleed moves onto the clip box instead. - The sheet's offsets are now clip-box relative. --band-from-pin is pin-relative and the box sits --pin-origin above the pin, so the two cancel: --band-from-pin + --pin-origin is --band-top. - --frame-h (measure()'s scroller.clientHeight) becomes unconditional. It fed the scroll-driven-only .fade-frame; .sheetclip needs it on both branches. Setting it on the fallback path is inert — .fade-frame's rule lives inside the @supports block and never matches there. Verified live against the pre-change rendering at identical scrollTop, each comparison bracketed by two baseline captures so the hero's 20s rotation could not be mistaken for a difference: 0 differing pixels at four of five stops (the fifth is one chip's hover ring, 83px), hero zone and scrollbody unmoved at every stop. Scroll range is now content-exact with the clip box flush to the pane at 1280x800, 1600x1100, 1100x620 and 1920x1400, and across artists with 4, 10, 11 and 22 rows. At max scroll all 11 rows are on screen instead of none. |

artist page: compositor scroll pipeline + final hero design (crossfade twins, mirror seam, bloom retired)
Scroll-driven animation conversion - apply() writes nothing per frame on the supported path; the hero squeeze, fade line and header curves all ride scroll-driven animations on the compositor. - Section boundaries flip via IntersectionObserver sentinels; the scroll listener is gone from the hot path. - The scrollbar thumb rides its own scroll-driven animation. - @supports-not fallback keeps the previous rAF --p path verbatim, so unsupported engines render identically. - Curves verified exact to 1e-6 against the old path, 0.000px continuity across boundary flips, correct retarget on resize. Perf fixes - Forced-layout reads pulled out of both scroll handlers. - Resize settle-reflow: a second reflow 200ms after resize quiesces, and the pane is observed too. This was the root cause of the fullscreen fade-wedge and of the long-standing intermittent where rows stayed hidden after a resize. Glass - backdrop-filter removed from chips and preview surfaces. - Bar glass blur 20 -> 12. - Choose-hero pill removed from the UI; pickArtistHero/clearArtistHero backend is untouched and the control can be re-homed later. Hero design (final) - Crossfade twins are permanent. Twin blur is baked via bakeBlur() (clamp-to-edge pad -> blur -> crop) so the frames stay pixel-aligned with no edge fringe and no geometry scaling. - Bloom strip retired everywhere; HeroGpuCanvas's internal bloom canvases are hidden by one scoped rule and the component is unchanged. - Seam is a pure mirror: the artwork's top strip flipped inside the glass band, clipped at the bar's top line, riding the squeeze with the hero and dissolving in lockstep on rotation. - GPU twin overlay crossfades on rotation instead of snapping — the incoming baked frame fades in on hero-banner-in with a 2-frame cap. - ~930 lines of experimental variants and the perf-flag system deleted; the surviving path is a pixel no-op against the approved configuration. Debug overlay - PERF/SEAM rows dropped; the overlay keeps stats plus an FPS/drops/worst counter (Ctrl+Shift+D). |

fix: artist page fade line no longer lags fast scroll (compositor-driven)
The content fade mask on .scrollbody lives in the scrolling element's local box, so its cut stop (--flow-cut) must ride scroll to stay at a fixed screen line. Driving that from heroScroll's rAF lagged the native compositor scroll by a frame on fast flicks, so the cut slid up and rows briefly showed above where they should clip (user-reported). Move --flow-cut to a CSS scroll-driven animation (@property + @keyframes + animation-timeline: scroll(nearest block), @supports-gated), so it's a pure function of scroll position evaluated on the compositor and can't lag. The keyframe delta and animation-range share one oversized constant (100000px) so the value is base + scrollTop for ANY scroll distance — necessary because the artist page changes its own content height as it scrolls, making the total range non-constant. apply() keeps the per-frame path only as the unsupported-engine fallback. Verified live: screen cut constant at 217px across scrollTop 300..2500, --flow-cut == base+scrollTop exactly. |

fix: preview crossfade no longer strands the main volume (silent playback)
Clicking a track could play silently: the store showed status=playing with the position advancing and no error, but the sink was at volume 0. The open/close crossfade ramped the main player's USER VOLUME as its fade channel and left it at 0 on an ack timeout (or when a track change suppressed the close resume). User volume persists across tracks and a new Play doesn't reset it, so every later click played at 0 while the slider still read 0.7. Give the main player a separate fade_gain channel (Cmd::SetFadeGain, sink = volume * norm * fade_gain), reset to 1 by every Play/Stop. The open/close fades ramp fade_gain instead of set_volume (their volume arg is gone, JS callers too), so the user volume is never touched -- store and backend can't desync -- and a clicked track always resets fade_gain to 1, so it can never be stranded silent. fade_resume lands exactly at 1. Player::fade_gain() mirrors it into a report atomic; debug overlay shows main fade + this proved the fix live (open 1->0, close 0->1, new track 1.0, volume steady at 0.7). 39 app + 12 player + 85 JS tests pass. |

feat: normalize preview clips to -14 LUFS to match the library
Deezer preview clips are cut from the raw master (not pre-normalized), so they played several dB hotter than the user's normalized -14 LUFS files — measured across one artist the previews ranged -0.1 to -8.8 dB from target, an 8.7 dB spread, so a flat offset would have been wrong either way. Each clip is now measured with the same BS.1770 meter the main player uses (preview.rs measure_clip_gain -> loudness::normalization_gain_db) right after it is written in preview_resolve -- off the async worker, and fully off the playback path on a prefetched neighbour. The linear gain is stored in the lease and the reuse cache, and rides UNDER the app-volume mirror per voice (effective = target_vol * clip_gain), so it composes with the slider, mute and the crossfade (each clip crosses in at its own matched level). Gated on the volume_normalization setting; reset on dispose. Debug overlay PREVIEW row now shows the active clip's norm dB. Verified live: per-clip gains -0.1..-8.8 dB applied; mute still zeroes the preview; 39 app + 12 player tests pass. |

fix: defer the open crossfade so main no longer fades into a gap
Opening the preview faded the main track out at focus-acquire time, but the first preview clip only becomes audible after resolve/load/decode — so on the way IN the 340 ms main fade completed into silence before the preview arrived (a gap the user heard; the exit was already fine). The main fade is now deferred: focusBridge.requestSilence only arms the commitment and grants; coordinator.beginMainSilence performs the actual fade-pause, and the service fires it from afterChange on the opening session's first audible clip (or ITEM_FAILED). Main-cos-out then overlaps preview-sin-in — a true cross. resumeMain skips the fade-resume when the fade never fired (close before audible), and beginMainSilence re-checks the main is sounding before fading. The focus coordinator's acquisition logic and tests are untouched. Verified live: preview audible at 275 ms, main played until then, faded ~343 ms, paused at 618 ms and held frozen; close resumed from the exact position in 15 ms. |

fix: previews follow the app volume; volume bar fill always accent
The preview backend never received a volume — clips played at the crate default (0.7) regardless of the slider, even muted. The session now sets the preview volume from the app store (mute → 0) before the first load and mirrors it live while the modal is open; the debug overlay's PREVIEW row exposes the backend's resting volume as proof. The player-bar volume (and fallback seek) fill is now always the accent color — matching the waveform scrubber's played region — stepping up to the hover shade on hover instead of white-until-hover. Also syncs package-lock to the soulstream name + alpha version. |

Preview modal audio, five rounds: - True track-change crossfade: scheduleSettle no longer silences the outgoing clip at t=0; preview_load's equal-power fade owns both ramps, gated on the incoming voice's first Playing event (audible_marks), with failure/overstay fallbacks. CROSSFADE_MS = 340 — locked to the reel's card-slide so audio and visuals land together. - Two-neighbour lease prefetch + a 15-min on-disk clip byte-cache (recent_clips): steps in BOTH directions crossfade in ~15 ms; revisits never re-download. - Adaptive settle (isolated steps fire immediately, bursts coalesce) and anticipatory auto-advance (step at clip end minus 400 ms) so auto-play crossfades over the tail instead of gapping. - Session resume memory: revisited tracks continue where they left off (decoder-level start offset via play_local_from/resume_at); finished tracks restart from the top. - Open/close crossfades with the MAIN player: fade-pause with the desired-paused latch landing at ramp end, fade-resume from the paused position; MAIN_FADE_GEN guards; focus handshake relaxation documented in focusBridge. Volume normalization (Settings > Playback, default on): - Dependency-free BS.1770/EBU R128 meter in the player crate (K-weighting, 400 ms gated blocks, incremental) + analyzer that reads the same growing file playback streams from — first plays are measured at download speed. - Gain layered under user volume; audible start GATED on a preliminary measurement (10 s of audio or 800 ms budget) so the level is right from the first sample and never changes mid-track; prelim boosts capped 3 dB, peak-aware clipping guard, persistent loudness-cache.json. - Gapless boundaries get their own sample-accurate gain via SetNextNormGainDb, fed by preload analysis. Debug overlay (Ctrl+Shift+D): process-tree CPU / PDH GPU / working-set + private-commit RAM / network rates / FPS / current-track download progress read from the backend's own StreamProgress / live normalization state / preview session phase. Polls only while visible. 131 JS + player + app tests green; every path verified live over CDP. |

Phase 2C: fix reel centering via window-relative card positioning
The transitioned track translateY collapsed to 0 in Chromium (percent- translated zero-height track), leaving the active cover one stride low per step. The track is now a fixed anchor at the reel centre; each card positions itself at (index - activeIndex) * stride and animates its own small `top`, so no coordinate ever exceeds +/-RENDER_RADIUS * stride. Verified with the transition ON: centre offset 0 at every index in the 12- and 500-item fixtures, 5 cards in the DOM at scale, wheel gates, dialog semantics, Tab containment, focus restore, and polite announce all pass. Dev window.__preview*/__ui handles removed from App.svelte. |

Phase 2C WIP: PreviewOverlay modal + root integration (reel centering bug)
Working: - PreviewOverlay.svelte mounted at app root; opens over a fixture manifest (window.__previewFixture(n) in dev), inert background, player bar hidden, focus trap, keyboard nav, F3 rail, T3 swaps, R1b capsule, accent extraction. - previewSession.svelte.js: store + service wiring (production + fixture). - Root integration in App.svelte; revision-gateway bumps + notePlaybackGeneration threaded through state.svelte.js player entry points; api.win guarded so plain vite browser mounts. - Launcher on the artist page builds a real artist manifest and opens the modal with a play-full starter. - 70 JS tests still green. Two bugs found and fixed during bring-up: - effect_update_depth_exceeded: bleed-crossfade and bump effects read AND wrote the same $state; wrapped writes in untrack(). This loop was breaking Svelte's scheduler globally (even ui.* stopped reacting). - accentFromImage now sets crossOrigin for remote covers. KNOWN BROKEN (handoff): reel vertical centering. The active card stays centred at index 0 but drifts by one stride per step. Root cause isolated — see TODO-Feature-Docs/scrollable-track-previews/HANDOFF-PHASE2C.md. |

Phase 2A+2B: native preview backend and renderer glue
Rust (2A):
- metadata: deezer_track_uncached (fresh mint, cache-updating, paced) and
fetch_preview_media — dedicated client whose custom redirect policy
re-validates every hop against the media allowlist; bounded body read
(cap enforced on received bytes, not Content-Length's promise); Date
header captured for provider-clock lease math. httpdate dep added.
- src-tauri/preview.rs: second Player instance + soulstream:preview event
channel; preview_resolve (fresh mint → host gate → MIME gate → ID3v2
shell strip → MPEG sync check → clip file + opaque lease id → safe_for_ms
mirroring lease.js); preview_load with start_paused via the
desired-paused latch; preview_control/dispose; player_pause_acked
exposing the Phase 0.4 ack on the MAIN player. 9 unit tests.
JS (2B):
- api.js: preview command surface (opaque lease ids only).
- nativeTransport.js: stamps {sessionId, generation, sessionKey} onto
backend events; cleared context makes stragglers dispatch nothing.
- productionResolver.js: DTO → MediaLease, failure classes preserved.
- focusBridge.js: production coordinator binding with the documented
renderer-side generation invariant (buffering counter + gateway).
- service.js: the orchestrator — settle window, resolve→load→play under
focus, single capped retry, one forward lease prefetch with safe-window
expiry, stale re-checks before every transport command, close/handoff.
The service constructs its transport around its own dispatch — the
factory signature exists because a pre-built transport silently loses
the event wiring (caught by test).
70 JS tests passing (npm test); metadata 46 + app preview 9 in cargo.

Phase 1: preview contracts and pure session core, 61 tests
src/lib/preview/ — framework-free ESM modules, per design §12–14: - contracts.js: versioned manifest/item/source-ref factories; signed URLs structurally excluded from manifests; Apple identity first-class. - lease.js: discriminated MediaLease union; computeSafeForMs derives lifetimes provider-clock-first with fallback/contradiction handling (margins are ADRs backed by Phase 0 soak evidence). - redact.js: URL redaction (host+hash+exp only) and the HTTPS + exact host allowlist gate applied to initial URLs and every redirect. - manifest.js: artist (rank order, exact-id dedupe), album (disc/track sort, context inheritance) and fixture builders — pure, no fetching. - session.js: reducer with session/generation guards on every async action; keyed active item with derived playable indices/cursor; auto-advance under fresh generations; close is terminal. - resolver.js: PreviewResolver contract + scripted fixture resolver with classified failures (stale_lease/not_found/network/…). - transport.js: transport seam + deterministic fake (manual ticks). - focus.js: revision gateway (all main-player entry points; focus- internal tag) and the coordinator — acquisition only via a generation-bound silence ack, restore only with revisions unchanged. tests/preview/*.test.mjs run via `npm test` (node --test): 61 passing, covering the full Phase 1 list in IMPLEMENTATION-PLAN §6 including the exit gate: stale lease/play events are inert, no restoration after any simulated main command, and no component renders anywhere. |

Baseline: full tree snapshot after git repository loss
The previous .git directory was found gutted (only info/ remained), so history is unrecoverable locally. This commit restores version control with the tree exactly as it stands: the working app, the preview-tracks launcher on the artist hero, the scrollable-track-previews design bundle (docs + approved mockups), and the Phase 0 validation artifacts. |
