player bar: the album line survives library plays, and lands with the title
Two halves of one defect family. The meta line preferred the queue item's
artist/album fields as a PAIR whenever either existed — but a library play
(playAlbum) writes only `artist`, with the record's name living inside
`sub` ("artist — album"), so `album: null` was taken at face value and
every library album lost its name from the bar (and the morning comment
claiming local rows carry neither field was simply wrong). Each half now
falls back to the `sub` split on its own, here and in the rail's byline —
which also restores the album for continuation items whose `sub` is a
bare artist.
And the line no longer trickles in: the buffering branch used to render
the artist alone, so the album flashed in a beat after the title when
playback started. The status gate is replaced by a REAL distinction — a
resolver-phase track has no `path` (playQueueIndex always writes one), so
"finding best source…" still shows as a bare label, and the moment a real
queue item owns the transport the full clickable line renders, buffering
or not. Measured: the first frame carrying the new title already carries
artist · album; no artist-only frame exists.

player bar: the track-change morph stops being a coin flip
Two independent fragilities each collapsed the shape→shape morph back to a grow-from-dots, which is why it only sometimes worked. The hold was 600ms against an arrival whose timing is DECODE time: the same track costs ~5ms once the session holds its waveform in memory but hundreds of ms to over a second on the first cold decode. 2000ms covers the cold case with room; fresh-stream searches take well past that, so the loading story still gets the lane. And the hold bailed on a bar-count mismatch — but the lane's width follows the song TITLE now, so switching between a long and a short name resizes the lane mid-gap and the guard threw the held shape away. Held and morphed heights are refitted to the new count instead (nearest neighbour — it is a moving start point, on screen for under a second). Four consecutive cached switches measured after the fix: minimum lane height 15.1 on every one (dots are ~2, the old dip hit ~5). Gapless playback is untouched — the hold and morph are pure painting, and the sink-append path never waits on the lane. |

player bar: track changes morph shape into shape, not up from the dots
The arrival morph honestly started from whatever the lane showed — and on a track change the lane always showed dots, because the waveform empties the moment the queue moves. Every switch therefore played the same grow-from-zero, when the picked motion was one waveform transforming into another. A track change now HOLDS the outgoing shape for ARRIVE_HOLD_MS (600ms), painted in unplayed grey since the new track owns the transport. A quick arrival — a local file, a cached stream — lands inside the hold and the morph runs directly from the old bars into the new ones; a slow stream load falls to the dots-and-swell story when the hold expires, exactly as before. The rail mirrors the hold with the same shared constant, and suppresses the loading swell while holding so the keyframes cannot fight the held heights. Measured across a cached track switch: the lane's mean height never left 16.9-17.4 (the dots sit at 2, the old dip hit 5.2) while the per-column fingerprint changed — the shape transformed without ever falling. |

player bar: a complete waveform arrives as one motion instead of popping
Chosen on waveform-arrive.html (M2, direct morph, 1000ms): when a track has its whole waveform at once — a local file, a fully-cached stream, or the final decode replacing a stream's progressive peaks — every bar eases from whatever the lane currently shows straight into the new shape, all together. From the resting dots that reads as a uniform grow; from a mid-sweep swell or the previous track's bars it is literally one waveform transforming into another. The streaming rise keeps its left-to-right story untouched; the morph fires only on a peaks swap at coverage 1, and never on a resize, which re-lays the same shape and stays instant. The canvas keeps a record of what it actually painted last frame — dots, swell, rise, morph or settled — so the morph always starts from the truth on screen, and the fade colours (accent, boundary blend, hover wash) stay live through it. The rail mirrors the motion in CSS: an `arriving` class carries the same 1000ms house-ease height transition, placed after the rise rule so a stream's final decode arrives on this ease too. Measured live on a cached start: bar heights walked 5.2 → 8.2 → 10.6 → 12.3 → 13.6 → 14.6 → 15.0 and settled at 15.1 at the 1000ms mark — the ease-out curve, frame by frame. |

playback: the album button and the background fill learn the cache too
The cached-source skip only covered single track clicks; pressing Play on an already-streamed album still resolved from scratch, and the background album fill searched for every remaining track it appended. Three closures: Play-album first asks the memory for every track of the record, and when all of them are still byte-complete in the cache it queues the whole album from memory — no search, no popup, playable offline. One unknown track falls through to the resolver as before. The resolver's own queue build now remembers EVERY track of the folder it picked, not just the one that plays — one album resolve teaches the whole record, so the next press of Play skips straight to the cache once the files have finished arriving. The background fill checks the memory before searching for each appended track, and remembers what it appends, so a record that has streamed before extends its queue instantly instead of running one 7-second search per remaining track. Verified live: the remembered track went from click to playing in 114ms with the resolver never activating. |

playback: a cached track plays without asking Soulseek where it lives
Hopping between songs of an already-cached album still ran the full "finding best source…" resolve for audio sitting complete on disk — a second of popup between every click. The player now remembers the source each stream item was queued from (localStorage, LRU-capped at 400) and, before any search, asks the backend whether that exact file is byte-complete in the stream cache. If it is, the track plays those bytes immediately: no resolver, no popup, and no online requirement — cached audio is playable offline, so the check sits before requireOnline. The memory is a hint, never a promise. It is written eagerly when an item is queued to PLAY, because a source that never delivers leaves no complete cache file and the byte-complete probe rejects it later at no cost; eviction and half-finished transfers fall back to the normal resolver the same way. First play of a track records it, every play after that is instant. |

player bar: the name sets the width, and the waveform stops flattering the clamp
The source chips are gone — the rail already tells that story — and with them the measured slot, its effects, and the bar's only container query. The now-playing cluster hugs the song name with no cap, giving ground only once the scrubber hits its 260px floor; the artist's 55% ceiling applies only when an album sits beside it, so a lone loading artist no longer renders as two letters in a twelve-pixel box. The waveform is rebuilt on honesty. WAVE_BUCKETS rises 400 → 2000 (~128ms per bucket — at 400, every display bar was ~2s of audio averaged twice), and one shared shaping in waveshape.js replaces both lanes' gain-into-clamp rule, which flat-topped 53.8% of the bars on a real decode and was propped up by per-bar noise in the rail — deleted; the lane shows the record, not a hash of the bar index. Bars fold with a mean+peak blend and stretch across the track's own p05–p97, so a loud master stops pinning to the ceiling and a quiet one stops vanishing. The playbar copies the rail's fade verbatim: whole bars blend accent→grey with cuts landing in the 4px gap, and the one bar under the playhead crossfades toward whatever its neighbours are — the wash while hovering, the muted grey otherwise. The redraw gate watches that blend instead of a 0.75px playhead move, so both lanes now step on every position event. Loading is drawn, not implied: the solid fallback bar is gone and the lane is always the bars, always seekable. Empty, it rests as the rail's dots; a swell crosses them while a waveform is computed (2s sweep, 0.5s rest); a streaming track's bars stand up left→right on a 40ms cadence, each rising over 2s. The rise frontier is the waveform's OWN coverage, reported by stream_waveform beside the peaks — the old contract zero-padded partial peaks to full length and let the UI fold them against a fresher byte count, which stretched the whole shape between refreshes. Where the bars end is how much of the track has actually loaded; cached and local tracks arrive at coverage 1 and pop in complete. The first partial is also requested eagerly (fresh refresh clock per track, 700ms retries until peaks exist), closing most of the audio-before-lane gap. |

player bar: one row, aligned to the sidebar's column, and it says who is sending
88px becomes 62px and the two stacked rows become one. The 26px goes back to the content area on every screen, and the scrubber stops capping at 560px while the flanks stretch — a 1900px window used to put a small waveform adrift in the middle of an empty bar. The cover is 40x40 at 12px of padding, which lands its centre on x=40: the column every sidebar cover and nav icon already shares, and which the sidebar holds through its entire collapse. It was 56px at 16px, centre x=52 — twelve pixels out of a column the app is otherwise strict about. The waveform is drawn as discrete bars on the Now Playing rail's exact pitch, a 2px bar on a 4px gap with a 1px radius, both deriving their count from that one pitch so neither can drift from the other. Mirrored here, where the lane is short and wide; the rail stands its bars on the floor because it sits above a caption. The standing white playhead went with it — at this pitch it read as a seam through the bars, and the accent's own leading edge marks the position. Artist and album share one line as "Artist · Album", the `.who` idiom from the album page rather than a new one. They are read from the queue item's OWN artist/album fields now: `sub` is a display convenience that the album continuation fill writes as a bare artist while carrying the album right alongside, so a record played straight through lost its album name from the second track on. When the line must shrink the ALBUM shrinks — proportional shrinking turned a short artist into "Po…", which saves nothing and reads as nothing. New: the source line. Who is sending this track, how much has arrived, how fast and how long is left, then the format. Four states, derived exactly as NowPlaying derives its status line — two surfaces disagreeing about whether a track is cached would be worse than either being wrong. A library file reports NOTHING, because it has no peer and no transfer and zeroes would read as a stalled one. It sits in its own slot rather than inside the meta cluster: sharing that budget let a live transfer readout crowd the artist and album down to "Po… · Terrestria…". Its width is measured per STATE and never per value, so a ticking percentage and a counting-down ETA move nothing. The now-playing panel toggle is gone from the shelf — the panel carries its own collapse control, and two ways to do one thing is one too many. What replaces it is a single overflow menu, so landing lyrics, a mini player and output switching later costs no width; those three are present and disabled, marked SOON, rather than wired to nothing.

search: the results page, the typeahead, and a session that survives a reload
The page is the signed-off prototype built out: floating rounded hero, inline top-tracks panel, filter chips, two-column Songs|Albums beside Artists, and all seven states — results, searching, no results, one-kind-only, library-empty, provider-unreachable, first visit. MusicBrainz records are merged in silently behind the Deezer rows. The top result is ranked by POPULARITY, not by kind: each kind puts up its most popular exact match and the winner is whichever holds the largest share of its own kind's leader. A raw fans-vs-rank comparison was tried first and handed "panda bear" to an Owl City song. Two provenance traps are paid for here. Deezer's /search/album returns no release_date at all, so sorting newest-first ordered by PROVENANCE rather than by date; dates are backfilled from the artist overview, resolved PER ALBUM ARTIST because Deezer's artist search answers nothing for "weezer blue album". And the typeahead holds its keyboard selection as the row's KEY rather than its index, because the MusicBrainz supplement lands ~600ms later and re-orders the album group under the cursor. The hero's middle third is hidden on the width of the PANE, not the window. The sidebar and the now-playing rail take ~490px between them, so a 1504px window can leave the hero 1012px — a window-width media query cannot see that, and the "latest release" card ended up sheared down to 26px of itself. The budget is written out at the @container rule. Session restore rounds it off: reload or restart returns to the same place with the same track, everything but the transport coming from localStorage.

albums: ask the artist's own discography before deciding a record does not exist
"A ? of WHEN" opened as a bare local page — no plays, no listeners, no real release date — while the artist page's expander showed all three for the same record. The artist page was right and the resolve was wrong. Deezer's SEARCH index is not the discography. The artist page merges a MusicBrainz supplement on top of it, and MB-only records get a real id, a real release date and full Last.fm figures there; the Deezer search that openAlbumByName ran simply cannot see them. So the resolve now falls through to the artist's own album list before giving up. That list has to be the SUPPLEMENTED one. getCatalogArtistPage returns the raw Deezer page until the artist page has been visited and written the merged version back into the cache, so a cold click still missed. It now runs mergeArtistIdentity itself — the same pure merge the artist page and the Now Playing panel already share — instead of concluding the record is nowhere. Verified against the artist page's own numbers: id 5831190465731370, released 2026-07-10, 4,521 plays, 236 listeners, per-track 66/131/113/108 — identical to the expander. The local-composition path stays as the last resort for a record genuinely in neither catalogue, where it is still the only thing that can render at all. |

albums: one page for every record, and streamed history rows that actually open
Three things were wrong with opening an album, and only one of them was the one that got reported. The reported half: clicking a local record in the sidebar's history went to the old in-library album view. Local albums carry no catalog identity of any kind -- `albums.mbid` is null and is not even in the DTO -- so there was nothing to route with. openAlbumByName already existed for exactly this (the now-playing links use it, and it requires BOTH artist and title to match normalized, which is the namesake guard); it now reports whether it resolved and caches settled answers, so a second click is instant. The unreported half, and the reason "half of them are not working": every STREAMED row was dead. catalog_album_id is TEXT in SQLite, so it arrives as a string, and `catalog_album` takes a u64 -- the invoke was rejected outright with "invalid type: string ... expected u64". Terrestrials, OK Human and 9 all failed silently on click. The id is coerced in checkedAlbumPayload now, where both other string sources (page seeds) pass through too. And the part that made the first half unfixable: a record no catalog carries had nowhere to go. Panda Bear's "A ? of WHEN" is not on Deezer, so no amount of resolving would ever open it. Local albums now render on the SAME page, composed from the library's own data -- its tracks, durations, bitrates and the cover already on disk -- under a namespaced `lib:` id that can never collide with a Deezer one. Playback stays local: Play and any row queue the files you already have rather than sending a record you own back through the resolver. Save is not offered (it is already saved), previews are absent (there is nothing to preview), and the attribution footer credits your library rather than claiming Deezer + MusicBrainz. With that, the old view has no callers and is deleted: the album-page block, its CSS, and the members that only it used. Nothing anywhere routes to it. Verified live: all six history rows open the new page, a Home card opens it, Play queues 14 local FLACs without streaming, and the back arrow returns. |

recents: a streamed album has no library id, so the key must not pretend it does
The sidebar history looked completely dead -- albums never appeared, the
list never updated, and often nothing was there at all. The backend was
fine the whole time: 460 play rows, recent_albums returning every album
correctly.
The list is a keyed each on `a:${album_id}`, but catalog-anchored rows --
every streamed play -- carry album_id NULL by design and are identified by
catalog_album_id. One streamed album in history keyed `a:null` harmlessly.
The second one collided with it, the keyed each threw, and the whole list
unmounted; every later refresh fed a dead component. It demoed clean
yesterday only because history had just been wiped and exactly one
streamed album existed.
Keys now carry the id realm, the same two-realm split isPlaying and
openRecent already used.

previews: the glow goes, the eq steps, and every clip lands before you scroll to it
The track preview modal could hold a machine at 25% GPU. Three separate causes, each measured in isolation with a kill-style ladder and, once the GPU-engine counter proved to be clock-relative (a lighter workload read HIGHER), with clock-immune process CPU-seconds. Idle drain. The scrim's backdrop-filter is re-executed on every presented frame -- a backdrop filter is never cached -- so its cost is presents/sec times window area. Two infinite animations kept the modal presenting at the display's refresh rate forever: the eq capsule's bars animated `height` (a layout property, so style/layout/paint on the main thread every vsync) and the cover glow's halo-breathe kept a blur(48px) copy recompositing. Either one alone kept the pipeline hot, which is why killing one changed nothing. The glow is deleted outright at Kyle's request; the eq bars now scale with a stepped transform whose three delays are multiples of the step interval, so all three jump on the same instants and one present serves them all. Playing steady state: 7.2-10.5% of a core down to 1.4-2.2%. Paused: 0.2%. Scrolling. The animations turned out to be innocent here -- reverting them moved the number not at all. The cost was per-step work: re-decoding the full artwork for the background wash, a main-thread accent scan, a new cover mount, three times a second. The wash is now a 96x58 canvas with the blur/saturate/brightness baked in at draw time and cached per artwork, and an overlay preloader walks the manifest once at open -- nearest to the active card first, capped at 60 -- filling the decoded-image, wash and accent caches ahead of the user. A rapid-nav jump-cut was tried and rejected on sight; the animations stay full at every rate. Backend. preview_resolve swept the clip directory on every call, and any landing outside the +/-1 prefetch window paid a full Deezer mint, download, validate, write and loudness measure. The fetch-store-measure core is factored out and a new preview_prewarm walks the session's track ids at open, paced 250ms on top of the existing Deezer throttle and starting 1.5s in so the first clip owns the network, halted by a generation guard on dispose. A burst landing on a never-visited track is now audible in 154ms off local disk. The sweep is throttled to ten minutes, and dispose deletes prewarmed files instead of orphaning them until the hourly reap. The debug overlay's GPU row was summing the counters machine-wide, so it read roughly double the app's share with Discord and DWM folded in. It now reports `app X% - sys Y%`, the app figure restricted to our process tree, matching Task Manager's per-process rows. |

loudness: a first play starts three quarters of a decibel under the prefix
The prefix estimator is BIASED, not merely noisy, and the sign is known: a quiet opening under-reads the track, so the head asks for too much gain far more often than too little. Subtracting a constant moves the whole distribution toward the truth, so a first play begins nearer its real level and the correction that follows has less ground to cover. Measured by a new `head_start_offset_sweep` over 1046 tracks sampled across 182 artists — at most six per artist, spread across each discography rather than taken from the front, since openers are where intros are least typical and intros are the whole source of the bias. The cached corpus it replaces was a dozen artists and put the median at +3.48 dB. Sampled diversely it is +1.55, so the old number was overstating the bias by more than double. The size comes from the MARGINAL trade, not the smallest mean error: step loud fixed quiet created ratio 0.0 -> 0.5 -89 +41 2.2 : 1 0.5 -> 1.0 -83 +85 1.0 : 1 1.0 -> 1.5 -61 +132 0.5 : 1 Only the first step is clearly worth taking. mean|err| bottoms out at 1.5 dB instead and is the wrong objective: it weights an error that begins decaying at once the same as one that waits for Analysis::Complete, which on the streamed first plays this path exists for is download-bound and therefore late. A constant is deliberately a weak lever. The per-artist median error runs from -4.58 dB (Boards Of Canada) to +7.03 dB (Ponytail); no single number fits everyone, and an offset shifts that spread without narrowing it. The levers that would are letting the follow recover UPWARD, and predicting the offset per track from the prefix. Both still open. The overlay reports it as a MOVE — what the prefix asked for, where the track actually started, and a ghost tick on the dB scale at the prefix position, so the gap to the applied gain IS the head start. Gated on `analyzing`: at Analysis::Complete the player releases to the whole-track gain while loudness.gainDb goes on reporting the prefix value, which it keeps for the next play. Without that condition the line advertised a correction that had already been released. |

now playing: the transfer moves into the bar, and the panel speaks the app's headings
The hover popover is deleted. It showed the peer, the rate, a percentage and a second progress bar — every one of which the status line and the hairline beside it already carry — so it was a duplicate you had to hover for. The two things unique to it move up: the save action into the bar, and nothing else. Deleted with it, the reveal action, its 250ms close grace and the `.np-statuswrap` hit area, all of which existed only to make a popover reachable across the 25px gap between the status line and itself. Release sections were the one heading in the app that was 13px, Title Case, full white on an opaque sticky bar; every other one — `.lab` here, `.disc-head` and `.rail-lab` on the catalog pages — is 11px uppercase muted. They now match, with the hairline rule the catalog pages use, and they no longer pin: the bar existed only to hide rows sliding under a sticky heading. Those headings sit on the blurred record, not a flat page, so `--text-muted` and #5c5c5c were chosen against a background that is not there. Each carries a dark plate now, years get the album page's over-artwork treatment, and the hairline goes 0.07 -> 0.14, which over a bright cover was the difference between a faint line and no line. "From the album" rendered `player.queue`, which the album fill grows ONE TRACK AT A TIME as each Soulseek source resolves — a nine-track record read "5 tracks" while you watched the rest arrive. It renders the record's own tracklist now, matched to queue items by provider id, and a row with no source yet resolves on demand when clicked. The About pane gains a record head, a lede, stat tiles, pills and a source line, all re-laid-out from data already in hand. The artist page's expander gets the same lede and pills — no record head or tiles there, because its rail already carries them. |

album page: the record's own shape while it loads, and prose that waits its turn
The loading state was one line of grey text, then the whole page at once. It is now the page with its words removed — the same hero, identity, cover and copy elements, so the artwork does not move when the fetch lands. The cover is real from the first frame: `albumSeed` carries what the card you clicked already knew, painted in 10ms, and the skeleton row count comes from the seed's track count so the tracklist grows 370 -> 377px instead of 296 -> 377. Three bugs found by measuring the handoff frame by frame: - Every dealt part rendered once at full opacity and then snapped to zero. `element.animate()` returns a PENDING animation whose start time is not resolved until the next frame, so `fill: backwards` never covered the first paint. Hiding each part inline is synchronous and closes it. - The deal was animating the SKELETON. `openCatalogAlbum` assigns `albumPage` and clears `albumLoading` only in its `finally`, so for one flush the new record was live while the placeholder was still on screen — and it has a `.tracklist` of its own. - The artwork could blink on a cold cache: the skeleton seeds the 500px grid cover and the page asks for the master. The seed now sits underneath as a background until the master decodes, on the banner too, where the blur applies to it and the colour wash survives the swap. The deal also only ran once, against a snapshot, so `.about`, `.eds`, `.stats` and `.credits` — all gated on network data — were never animated at all. Parts now record which generation dealt them and a later pass picks up whatever was missing. The description moves BELOW the tracklist. Above it, it pushed the tracks ~180px down and re-flowed them on arrival, measured at 81.5px; nothing above that point depends on `info` now, so the tracklist cannot move (measured 0). It gains the page's own `.disc-head` idiom, a promoted lede, and the bottom credits block becomes pills plus who said so. |

state: one identity merge, one description splitter, and a record named at click time
Three separate things the panel and the pages were doing differently. The MusicBrainz merge lived inside `applyArtistIdentity`, which only the artist page calls, so the Now Playing panel showed the raw provider list: My Bloody Valentine appeared with four releases because Loveless and Isn't Anything exist only as supplements, and Weezer filed differently because the panel never received `type_hints`. The merge is now `mergeArtistIdentity`, a pure function both surfaces run. `applyDiscoveryIdentity` deliberately does not write `catalog.artistPage` — that would overwrite whatever page the user is looking at — and is guarded on the normalized artist name so a track change mid-flight cannot land one artist's supplement on another's list. `streamSong` knew the record all along and never said so. Every caller passes `album` and `albumId`; the queue item was built with `sub: artist`, and the panel splits `sub` on the dash to find its album line, so a single track could never name the record it came from. `catalogRef` was also assigned AFTER the Soulseek resolve, so the panel could not start loading the record until a peer had been picked — that wait was the "why does it take time to show the rest of the album" delay, with the id in hand the whole time. It is now set before the resolve, and handed back if no source is found. `splitDescription` promotes a description's own first sentence to a lede. It lives here beside the other release-identity helpers because three surfaces need it and a copy in each is how they start disagreeing. The abbreviation guard is worth keeping: written as `Nov\.` the lookbehind consumed the very period it was meant to protect, and "released 4 Nov. 1991" split after "Nov.". |

loudness: correct the gain during the track instead of only guessing at its start
A streamed first play is gained from a prefix; every later play is gained from the whole track. Measured across the 89 cached tracks, a 10s head asks for a median 3.4 dB too much gain and is more than 1 dB hot on 68 of them — that gap is the "first track is so much louder" complaint. The curve never flattens either: even a 60s head is still ~1 dB out with a 6 dB worst case, so no window size fixes it. Live traces then showed something worse. The hard deadline was anchored to the play REQUEST, so on a peer that took a moment to start sending, the 2.5s ran out before a single gating block existed and the track began at unity — no normalization at all, three plays out of four on one run. Releasing early bought nothing in exchange: playback is blocked on the same bytes, so the gate was discarding the measurement without making sound arrive sooner. - The deadline now starts at the first byte, with an absolute 4s ceiling from the request so a slow peer cannot hold audio that is ready to play. - The audio thread's slew drops 2.5 -> 0.25 dB/s. Mid-track correction was switched off in July because the glide was audible; at a tenth the rate it is not, and being 3 dB wrong for a whole track is the larger error. - The correction follows the running measurement from its first publish and may only ratchet DOWN until the track completes. A convergence test lived here and was deleted: an integrated average over 30s cannot move much when one more second is added, so "3 publishes within 0.3 dB" was measuring the inertia of a long average, fired at its floor every time, and declared settled while 1.5 and 2.1 dB from truth. The protection was never the gate — it is the slew rate and the ratchet. - Seeking lands the pending correction immediately. The slew is slow only because a gain change is audible against continuous music, and a seek is already a discontinuity. Observability: SOULSTREAM_LOUDNESS_TRACE=1 reports every commit with the seconds analyzed, which limit fired, the hold, and the bytes received; the debug overlay gains a SLEW line showing applied gain, target, distance and ETA, because one number cannot distinguish "settled" from "in flight". Also adds an #[ignore] corpus harness that sweeps head-window bias in 30s. |

now playing: the drag tracks the pointer, and the panel stops fighting its width
The resize grip. The panel already left the 0.28s ease for a drag, but the grid column it lives in did not -- and an eased track list cannot follow a pointer, because the grip moves the target every frame and each move restarts the ease from wherever it had crawled to. Measured on the real gesture: the column ran 122.6px behind the pointer and the panel overran the window on 29 of 30 frames, which is why the release grid was sliced off at the right edge. With the column leaving the ease alongside the panel: 0px lag, 0 frames clipped, 4.6ms worst frame. onGripUp is bound to lostpointercapture as well, because a release the grip never sees would leave the app root pinned at transition:none and kill every collapse animation for the session. The header status re-ran its 300ms entry slide on every progress event. It was keyed on the text, and the text carries the percentage, rate and ETA -- so it replayed several times a second and the header flashed. Keyed on the transfer PHASE now: 2 rebuilds across a real transfer instead of one per tick. The waveform lane was unmounted while peaks were absent. player.waveform empties the instant a track changes and a partial FLAC decode can take seconds, so the times, the chips and the whole pane below jumped 54px up and then back on every track change. It holds its space as a flat baseline, with the same bar COUNT either way so peaks arriving restyle the existing elements rather than replacing them. The bar count is derived from the panel width at a 6px pitch as well -- a fixed 78 bars was a 310px block that overflowed the 272px panel and left a third of the 560px one empty. Now 41 bars at 272 and 89 at 560, never more than 4px of the lane unused. Fans also like was a fixed row of four circles spaced evenly: every name truncated to "The Sma..." however wide the panel got, because the circles stayed 64px and only the gaps grew. Name-sized pills that wrap use whatever width there is, carry eight artists in less height, and truncate nothing at any width. Show all releases dumped 68 records in one flat date-sorted grid. It is filed by the artist page's own ten categories now, empty ones dropped, editions folded into their base, as dense rows with the year printed only where it changes. NOTE: this panel classifies with less evidence than the artist page -- no description hints, no MusicBrainz type map -- so a record whose kind is only knowable from its description will file differently here until those are routed through. Commented at the source. Full-screen artwork from the panel opened playerArtSource, a string rewrite of the provider URL to 1000x1000, with no coverUpgrades lookup at all -- while the same record opened from a page gave the master. On the Red Album that is 1000x1000 against Apple's 3000x3000. It opens on the best it has and swaps the master in when it resolves, guarded on the viewer still showing what it opened. Releases grid: cards align on their artwork again (a button centres its content, so beside a four-line title the short card's whole stack sat lower), titles clamp to two reserved lines, the hover outline samples the record's own colour, and clicking one opens the album page instead of streaming it. The artist chip's name was centred because a button centres text while the stats row below is flex-aligned; it reads as left-aligned with them now. waveDragging is $state, so class:scrubbing actually applies. The pane never scrolls sideways. |

player: fill the album, report a cached track honestly, and stop double-appending
The album continuation appended exactly ONE track and then waited for the next track start to append the one after, so a song started from search or an artist page showed a queue of one or two entries however long the record was. It still resolves one at a time -- a track cannot be queued before a peer with it is found -- but it no longer stops after the first. My Name Is Jonas cold: 1 to all 10 in under 12 seconds, in album order. The resume anchor moved to the LAST queued track so a fill cut short by going offline picks up where it stopped instead of being locked out by the "next already queued" guard. An adversarial review of that change found the hole it opened, and it is fixed here rather than shipped: dropping the second clause of the bail-out was wrong. streamSong installs autoAlbum only AFTER waitForStreamStart, which polls the GLOBAL player status, so a second play issued during that buffering window nulls autoAlbum and streamSong then re-installs its own context over the top -- and the fill would go on appending one album's tracks to the other album's live queue. The anchor must also still BE in the queue, which survives our own appends and disappears exactly when the queue is replaced; and streamSong no longer installs a context it no longer owns. advanceGaplessly reported a pre-buffered track as zero-of-zero. streamTotal === 0 is the UI's "no byte counts yet" state, so a finished track showed the indeterminate "Streaming from <peer>" sweep with no further event ever coming to correct it. Gapless is only offered for a fully cached file, so its size IS its received count. The buffering handler mirrors the store rather than zeroing it for the same reason -- those counters are what a window restore copies back, and zeroing them turned a complete transfer back into the sweep on minimize and restore. tryAppendNext set its appendedNextPath guard AFTER its await -- check then act. Harmless with one caller; the moment the cached-play event gave it a second same-tick caller both passed the guard and appended the same source to the sink twice, which puts the panel a whole track ahead of the audio from the next boundary on. It claims the slot before awaiting and gives it back on failure. ui.nowPlayingDragging is here because App.svelte's grid column has to leave the 0.28s ease at the same instant the panel does. |

artist hero: the blurred layers ride with the photograph
Two layers were left behind when the hero rides up on scroll, both of them blurred copies of it, so both read as "the blur does not line up". The load seed and its mono twin were never in the squeeze-ride rule -- they got a filter on scroll and no transform at all, so at scrollTop 600 they sat 132px below where the photograph had gone. They were left out because hero-squeeze-ride sets transform outright and would drop the scale(1.06) they are built on; hero-seed-ride is the same translate composed AHEAD of that scale, so the offset stays in unscaled pixels and matches the banner's rather than being 1.06x it. Measured 0px drift at scrollTop 0, 300, 600 and 900. The mono twin is a BAKED copy of the hero canvas and snapshotGpuTwins only ever ran on a hero READY. So after any resize the live hero repainted at the new size while the twin went on stretching its old frame into the new box -- an overlay visibly off the photograph, and permanent until the next hero happened to re-bake it. It re-bakes when the measured box changes now, debounced past the renderer's own settle so it copies the canvas already repainted at the new size, and dimension-guarded so it costs nothing during the moving part of a drag. Verified: live store and baked twin agree at 3186x1629, then both at 2856x1607, then both back, with one frame throughout. |

hero: repaint on a resize instead of rebuilding the canvas for it
Collapsing the sidebar dropped frames only on the artist page. The cause was one observer: the app grid animates its columns for 280ms, a ResizeObserver fires on every frame of that, and this canvas answered each one with a full resize() -- 171-224ms of main thread per toggle, 10-12 frames over 16ms, worst frame 54ms. Muting that single observer took the worst frame to 4.3ms; muting every other observer changed nothing. Two independent per-frame stalls inside it. Reallocating the ~3200x1630 backing store was 115-205ms of the total, and the box moved about a pixel per frame, so every one of those reallocations bought an invisible sharpness change. gl.getError() after every draw is a synchronous round trip to the GPU process, and it stalls hardest exactly when the GPU is busy compositing the animation that provoked it. reflow() is the observer's path now: it repaints into the CURRENT store and matches the store to the box once, 140ms after the box settles. What makes that correct is taking the cover crop from the DISPLAYED box while outSize normalizes by the store -- the two may then disagree, because a crop chosen for a 1.80 box drawn into a 1.96 store is stretched by exactly the ratio the compositor undoes painting store into box. Geometrically exact at every intermediate width, no reallocation. The error check is skipped on that path only; the settle pass that follows is checked, so a real failure still surfaces. After: 1.5-2.4ms per toggle across 46 calls, max 0.2ms each. No frame over 33ms, 0-2 over 16ms. The Now Playing collapse rides the same transition and improved with it. resize is no longer exposed: every caller outside this file is reacting to a box that may still be moving, and that is reflow's job. |

now playing: collapse to a rail, and rebuild the panel around the record
The right-hand panel disappeared when you closed it. It collapses to a rail
now, exactly as the left nav does -- same 0.28s curve, same crossfade clock
for its contents -- so the record, its progress and its transfer stay on
screen at 64px instead of sliding off.
THE RAIL carries the album as a full-height bleed behind a real glass bar
(the app's own recipe: rgba(20,20,24,.28), blur(12px) saturate(1.7), 46px),
with the expand chevron in that bar, a left-edge progress line, the cover,
an equaliser while playing, stacked icons badged with what is behind them
-- tracks left, releases -- and the title set vertically.
THE PANEL stops saying "Now playing", which was the only permanently
visible line it had and told you nothing. It names what you are playing
FROM, and carries the transfer as a hairline along the glass bar's bottom
edge -- the same object in both states, so a download reads identically
whether the panel is open or collapsed. The hairline fills linearly (it
tracks progress rather than easing past it), sweeps indeterminately while
there is no byte count to be honest about, and fades out when cached rather
than sitting full forever. Hovering the header drops the whole detail:
peer, transferred, rate, and saving what you are streaming. A library track
has no peer, so none of it appears -- zeroes would read as a stalled
transfer.
Below the record, one long undifferentiated scroll becomes four shallow
panes -- Queue, Lyrics, Artist, About -- behind a sticky segmented control.
Sticky because keeping your scroll position across a switch is worthless if
the control you just used has scrolled out of reach. Queue gains an up-next
card, library ticks, and per-track Last.fm listeners past 396px; Artist has
the artist as one full-width pill whose figures spread once there is room,
the same branded social circles the artist page draws, releases with Show
all, and fans-also-like; About carries the record's description and the
album page's RELEASED block verbatim, so a record reads the same in both
places. Lyrics is a placeholder -- there is no source in the app and
pretending otherwise would be worse than saying so.
The panel is drag-resizable from its left edge, 272-560, with a 10px magnet
at the default and a width tag while dragging; the width is remembered,
because one you set by hand and lost every launch is worse than not being
able to set it.
Five things this fixed on the way, four of them mine:
- `playerArtSource` resolved a "better" cover by ARTIST + TITLE. A name
cannot identify a record: every self-titled Weezer album is "Weezer", the
resolver returned whichever one the provider answered with, and all of
them played back showing the Green Album's art. The substitution is gone;
the record's own asset is rewritten to its 1000x1000 variant instead --
a real quality win, no identity risk, and more than the panel needs even
at its widest. Verified: Blue and Green now resolve to their own hashes.
- The panel body was torn down 300ms after closing, an optimisation from
when it slid off-screen. The rail shows that artwork, so it blanked the
rail's cover and its bleed.
- An inline --nowplaying-width would have outranked the collapse rule and
made the panel un-collapsible; the dragged width goes through a
--np-open-width indirection instead.
- The segmented control was an opaque strip painted straight over the album
bleed, reading as a grey band across the artwork. It is glass now.
- The waveform was a picture of a scrubber with no way to seek, while the
player bar carried the only one. It seeks now, on the same semantics
(75ms throttle dragging, exact seek on release), and the second time
reads remaining rather than total -- the total is already implied by the
bar's length.
`soulseek:stream` reports {received, total, done} and no rate, unlike the
download path's speed_bps, so the speed behind the hairline is measured
here: a rolling 1.5s window, because a per-event delta reads as a number
flickering between 0 and several MB/s rather than a speed. There is
deliberately no "queued at peer" state -- the streaming path reports no
queue place, and the panel will not claim to know one.
`discovery` keeps the artist page's socials rather than discarding them;
they were already being fetched. 29 CSS rules for the removed sections are
gone with them.
Verified in the running app over CDP: collapse to exactly 64px and back,
rail contents and bleed at blur(17px), all four panes, sticky segments,
social chips carrying the artist page's own brand tints, the release grid
going to three columns past 430px and the pill's stats spreading past
372px, and About reading "Released May 9, 1994 - 10 tracks - 41 min / DGC -
Alternative Rock". 85 JS tests pass, production build clean with no unused
selectors. The drag gesture itself is not CDP-drivable and wants a
hands-on check.

navigation: one glass bar for the app's life, not one per page
The bar was rendered by each view, so `<CurrentView />` swapping on every
navigation destroyed it and built a new one. Measured: the `.glassbar`
element is not the same node on either side of an artist -> album move, and
the old one is disconnected.
That broke the crumb entrance animation, which is what this was noticed
from. The `seen` set exists so only a genuinely ARRIVING crumb slides in,
and it is component state -- so it was empty on every mount and every crumb
looked new. Instrumenting Element.animate across one navigation:
AC/DC -> Highway to Hell should animate: the album
actually animated: all three crumbs
Back to AC/DC should animate: nothing
actually animated: both crumbs
So the whole trail re-flew in from the right on every page change, and Back
animated crumbs that had never left -- the exact opposite of the
direction-of-travel cue the animation was written for.
The bar is app chrome, not part of a page, so App.svelte now mounts it once
as the scroll pane's first child and pages no longer carry it. Views that
do not show it yet hide it with `display: none` rather than an {#if}: the
element leaves the layout and measures zero -- scrollbar.js reads this
bar's height to start the thumb below it, and correctly gets 0 -- while the
component stays alive and keeps its crumb memory across the round trip.
Geometry is unchanged, which the negative-margin bleed made easy to get
wrong: the bar's net flow height is zero either way, so moving it from
first-child-of-the-page to previous-sibling-of-the-page leaves the page's
top exactly where it was. Verified against the live pane -- bar top/left/
width flush with the pane and 46 high, page top at pane + 24, z-index 40
and elementFromPoint at the bar's centre still returning the bar rather
than the hero underneath.
After: arriving at an album animates only the album's own crumb, Back
animates nothing, and a trip out to Library and back animates nothing. The
backdrop-filter layer is no longer recomposited on every page change, and a
bar element can now transition between pages at all, which was impossible
when each side was a different node.
Two consequences worth stating. The resolver pulse takes the GLOBAL accent
everywhere now; on the album page it used to inherit that page's extracted
palette, because the bar sat inside `.album-page`. The artist page always
gave it the global accent, so the two now agree rather than disagreeing.
And putting the bar on the remaining pages is now widening BAR_VIEWS plus
deciding how it sits against each page's existing header -- the mounting
question is settled.
85 JS tests pass.

previews: the album button opens the record the previewed track came from
The third action in the preview modal's control row has been a disabled stub since the modal landed -- there was nowhere for it to go until the album page existed. It goes there now. The target is the item's own provider `albumId`, never a title match, so a top-tracks preview lands on the exact record the modal's metadata line is already naming: Elephant Gym's "Light" opens Angle, and AC/DC's "Highway to Hell" the album rather than any of the compilations carrying it. The manifest has carried `albumId` and an `actions.openAlbum` flag from the start; all 20 rows of a Deezer top-track payload declare one. The navigation lands on the previewed TRACK, not just the record -- the album page's existing pending-track flash does the scrolling and the highlight, the same landing the now-playing song link already gets. Three details that are not obvious: - The overlay must not import state.svelte.js (the module comment on previewSession explains the cycle), so the navigator is injected by the page exactly as `playFull` already is. - Both ids are read out of previewUi and the snapshot BEFORE the close, not after: closePreview() nulls the callback and drops the snapshot the active item came from. And the close happens first, because the session holds the audio focus and navigating under an open dialog would land the new page behind the scrim. - contracts.js freezes every manifest id as a String, while `catalog_album` takes a u64 -- a JSON string fails to deserialize -- and the album page's flash compares track ids with ===. Both cross back to numbers in openAlbumFromPreviewItem, once, rather than at each call site. An album session is already standing on the record it would open, so the button greys out there with "You're already on this album" rather than re-navigating to the page underneath. The decision is made from the manifest's own contextKey, so it holds for any future surface that opens an album-kind session. The album page still supplies the navigator, so a row that ever declares a different album goes somewhere instead of being silently dead. Verified in the running app over CDP: artist top-tracks preview -> click -> lands on Highway to Hell (id 9410086), pendingTrackId 92719900 as a Number, matching track found on the page, .trow.flash present, modal gone, and the glass bar trail reading Search -> AC/DC -> Highway to Hell. From an album session the button is disabled and a click changes nothing. 85 JS tests pass. |

listener bars: a bar is never narrower than the number standing on it
Two faults in the tracklist's listener column, both visible on any record with one runaway hit. The bar was a LINEAR share of the album's biggest song, so a single outlier took the whole column and pressed everything else into a sliver. Weezer's Green Album is the case: Island In The Sun has 11.9x the listeners of that record's quietest track, so nine of the ten bars lived inside the bottom 8% of a 168px column and stopped being tellable apart. And the fill was absolutely positioned with the number floating on top of it, so a short bar left its own digits hanging off the end onto the row background. Six of the ten rows on the Blue Album did this. The share is now raised to a power below 1 (0.42). That is strictly monotonic and still anchored to the PEAK, so the ordering survives and a genuinely flat record still reads flat -- a min/max normalisation against the album's own quietest track was rejected for exactly that reason, since it would stretch Maladroit to look as varied as Green Album. Measured in the running app, shortest bar of a 168px column: album top:bottom before after Weezer (Green Album) 11.9x 8% 38% Make Believe 6.7x 15% 45% Weezer (Blue Album) 3.9x 26% 56% Weezer (White Album) 2.3x 43% 70% Maladroit 2.2x 46% 72% The flat records move least, which is the point: the curve spends its lift on the albums that were squashed and barely touches the ones that were not. For the second fault the number moves INSIDE the fill, and the fill gets `min-width: max-content`. The floor is then per-row and measured by the browser in the real font -- nothing in JS could do that honestly -- and the width handed over is only ever a lower bound. Across the four albums above, numbers hanging off their bar went from 6 to 0 and every bar stayed monotonic in its count. Green Album lands at 38% rather than the 35% the curve alone gives, because the text floor takes over on its shortest row. A track Last.fm has no count for keeps its dash and now gets no paint at all; a floor-width pill behind an em dash would read as a measured tiny value rather than an absent one. The scale moves to src/lib/listenerBars.js because the album page and the artist page's open-in-place album panel draw this identical column, and a second copy would quietly disagree with the first about how big a record's hit was -- the same reason editions.js was lifted out of the artist page. Both call sites verified over CDP; 85 JS tests pass. |

navigation: one glass bar for every page, with a history and a path in it
The glass bar was copied into two views and each carried its own contextual
back link — "Results" on the artist page, the artist's name on the album page.
It is a shared component now (src/components/GlassBar.svelte), and it carries
the app's navigation: back/forward arrows, and the trail to where you are.
**History and the trail are different things, and the file keeps them apart.**
History is a SEQUENCE — every place visited, in order — and it drives the
arrows. The trail is a HIERARCHY, derived from the current place, never from
history. That is why switching between two editions of a record adds a history
step but does not add a crumb: a breadcrumb built out of history would read
`Search › Weezer › Blue Album › Deluxe Edition`, which says the deluxe sits
inside the original. It does not.
Crumbs improve in place. An artist page opens on an id and learns its name and
portrait a moment later, so the crumb starts as a placeholder and is refreshed
through ONE call site (`rememberArtistSeed`), guarded so remembering a seed for
a row in some list can never rewrite where you are. Search results are the
journey's root rather than a bare "Search" — the crumb reads “weezer”, which
is the thing you actually want to get back to.
Arriving crumbs slide in from the right; only genuinely new ones animate, so an
ancestor that was already there does not re-run its entrance when the tail
changes. Chosen from four motions mocked against a real navigation stack.
Every navigation now goes through a recorder. A bare `ui.view = "…"` is a
destination the back arrow can never return to, so the sidebar routes through
`goToView` and the catalog openers record on arrival.
**Scroll position is remembered.** Going back returns you to the paragraph you
left; arriving somewhere new starts at its top. The difference is exactly
whether the move came from the arrows/trail or from a fresh click. Two details
that mattered: the offset is captured at the START of a navigation, because the
scroll pane outlives the view swap and by the time a page has been replaced its
scrollTop already belongs to its successor; and restoring is not one assignment
— the artist page paints a skeleton, then an overview, then the full
discography, so a single `scrollTop = 900` clamps to whatever height exists in
that frame and lands near the top. It re-applies until the target is reachable
and gives up the instant the reader touches wheel, key or trackpad. The album
page never reset its scroll at all, so a record opened from half-way down an
artist page began half-way down; it does now.
**The artwork lightbox serves any cover.** It was hardwired to the playing
queue item; `ui.fullscreenArt` (a boolean) is now `ui.artwork` (a descriptor),
so Now Playing, the artist page's expander rail and the album hero all open the
same viewer with their own `{src, local, title, subtitle}`. Each passes the
UPGRADED cover rather than the sized variant it paints — the point of the
viewer is the master resolution.
Hovering artwork offers it: the whole element lifts under a light wash with the
expand mark centred. `transform`, not a width change — on the album page the
copy column is sized to end level with the artwork, so a reflowing hover would
twitch the entire hero. The three numbers (--art-grow 1.035, --art-motion
160ms, --art-wash) live in global.css rather than being typed into three files.
Now Playing's corner expand disc is gone: one gesture for "open this artwork"
everywhere instead of a disc in one place and a lift in the others.
On the artist page the expander's album NAME now opens that record's page.
Also removed: the album page's scroll-triggered title takeover. The breadcrumb
names the record permanently, which made it redundant — the build was already
flagging its CSS as dead.
**And the fix this session actually turned on.** Kyle reported the album
tracklist's counts as "heavily glitched": Pinkerton showed El Scorcho at 636
listeners beside Tired Of Sex at 606,324. Switching the column from plays to
listeners changed nothing, because both were wrong for the same reason.
`artist.gettoptracks` returns a popular song many times over — once as itself,
then again for every "(Album Version)", live cut and remaster — listeners
descending. The fold meant to keep the first entry, and its comment said so,
but it was written `if by_key.insert(k, v).is_some() { continue }`.
`HashMap::insert` returns the previous value AND STILL OVERWRITES, so the guard
correctly skipped the ranked push while letting every later duplicate win the
map the album tracklist reads. The last re-listing — the most obscure pressing
— is what reached the screen.
Measured against the live API for Weezer: Buddy Holly is rank 1 at 2,351,642
listeners and rank 679 as "(Album Version)" at 1,919; the page printed 1,919.
My Name Is Jonas 1,100,251 → 870. El Scorcho 654,071 → 636. Pink Triangle
810,659 → 6,070. Only songs Last.fm lists exactly once — "Tired of Sex",
"Across the Sea" — were ever right, which is why the column looked plausible in
places and absurd in others. Twenty-four entries for "The Good Life", twenty
for "El Scorcho".
The fold is now `fold_lastfm_duplicates`, pinned by two tests using those real
figures. It also repairs Popular's plays and the album totals, which read the
same map. The tracklist column shows listeners in both places it appears — the
album page and the artist page's expander — because leaving one on plays would
have let one record disagree with itself.
152 Rust tests and 85 JS tests pass.

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.
150 Rust tests and 85 JS tests pass.

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. |
