fix: speak the shape the server actually sends - #203

Conversation
`src/lyrics.rs` renames the whole `LyricsList` struct to camelCase, envelope included. `api.ts` declared `track_id` / `structured_lyrics`, so `value?.structuredLyrics[0]` — written as `structured_lyrics` — threw on the first property and took the whole "now playing" page down with it. The `StructuredLyrics` type beside it was already correct: the inside was converted and the envelope forgotten. Nothing caught it because the e2e mock was written from that type rather than from the server, so the suite confirmed the client's account of the wire instead of testing it. The mock now answers the server's shape, and it can carry real words: an empty sheet renders the same "no lyrics" line under either name, so only an assertion on the words themselves tells the two apart.

`/api/v2/scans/{scan_id}/events` opened with a `snapshot` carrying a
`ScanJobRecord` and then sent a `progress` per step carrying the scanner's own
`ScanProgress`. The two agree on ten fields out of thirteen and disagree on
three: `id`/`scan_id`, `total_files`/`total`, `processed_files`/`processed`. A
watcher that bound the snapshot therefore showed its totals as absent from the
first progress frame on while its per-outcome counters kept working — which
reads as a display bug rather than as two shapes on one stream. The web client
showed "undefined files of undefined" above a correct "164 added".
The stream converts through `ScanProgress::record` now, and `ScanProgress` is
no longer `Serialize`: the other shape cannot come back, because there is no
way left to put that type on a wire. `ScanProgress` also leaves the OpenAPI
components, where it described nothing any route answers.
What the compiler cannot check is that the conversion puts each number where it
belongs — eleven of the thirteen fields are `i64` or `Uuid`, so a transposed
pair type-checks perfectly. That is what the new test pins, with thirteen
distinct values.

…sentence `GET /api/v2/scrobble-destinations` published finished English prose in `unavailable`, and every client printed it verbatim — including this one, which ships in English and French. A French reader was told, in English, what to change in a configuration file. A reason only helps whoever can read it. What crosses the wire is the case now and the wording belongs to whoever is doing the telling: `no_application_configured` and `browser_journey_needs_https`, both naming something an operator can change. **This changes the API shape**: the field is still `unavailable` on an unavailable destination, and its value is no longer a sentence. An unrecognised case must not become a blank — a server is free to be newer than the client reading it — so the screen falls back to saying the server did not say why, the way it already treats a queue failure cause it has not been taught. The e2e test asserted the server's own sentence, copied into the spec, so it agreed with the server about a string neither should have been sending. It asserts the words this client chose now: asserting on the code would be satisfied by a page printing the code raw.

`/api/v2/artwork/{hash}` requires an `Authorization` header, so `<img src>`
cannot fetch it and each thumbnail costs a `fetch` and an object URL of its
own. Every `Artwork` started its own on mount: opening the album page of a
164-track library sent 127 requests in half a second against a connection limit
of six, and the covers below the fold were queued ahead of the ones being
looked at, so the visible page filled last.
An `IntersectionObserver` with 300px of lead asks only for what is about to be
seen. This does not make the requests cheaper; it stops making the ones nobody
asked for. Where the browser has no observer — an old engine, a stubbed DOM —
every cover loads at once, which is exactly the previous behaviour: the other
direction would leave a page of empty squares nothing will ever fill.
A ticket like the stream's would let `<img src>` work and the HTTP cache serve
between sessions. That is the deeper fix and it is not this one.
The test asserts the property rather than a count: a count depends on the
viewport and would have to be loosened until it stopped meaning anything. The
card sixty rows down is not asked for, and scrolling to it asks. No e2e fixture
had ever carried an `artwork_hash`, so none of this was exercised at all.

Review caught the type contradicting the code beside it: `ScrobbleUnavailable`
named exactly two cases while `unavailableReason` deliberately handled a third,
which it could only express by widening through `Partial<Record<string, …>>`.
That is the same fault the rest of this branch removes — an assertion about the
wire that the wire never made — reintroduced two commits later.
`KnownScrobbleUnavailable` is the closed union, and it is what the translation
table is checked exhaustively against, so a case added on the server still
fails to build until this client has words for it. `ScrobbleUnavailable` is
that union plus `string & {}`: open, autocomplete intact, and honest that a
server may be newer than the client reading it.
The fallback was already there and already right; nothing had ever shown that
it fires. A test does now — an unrecognised case reads "this server did not say
why" rather than leaving a blank where a reason belongs.

…iven Opening the union widened the lookup key to `string`, and a plain object answers for names nobody put in it: `toString`, `constructor` and every other inherited name come back off the prototype, truthy, and were handed to `t()` as if they were translation keys. The previous commit introduced this while fixing something else — the open type was right, the object read under it was not. A `Map`, for the reason `REASONS` above is a `Set`: it holds only what was put in it. The exhaustiveness check stays on the object, so a case added on the server still fails to build until this client has words for it. Three inherited names are now tested by name. They are not cases any server sends, which is the point — they are what an open key admits by accident, and each must read as a case this client does not know.

Closes the Phase 1.j loop on the web side. The DTO field was already there since 1.g.2, but the route previously rendered an ordered list with title + artist only — duration_ms was carried but ignored, and the page header showed neither a track count nor a runtime. Wire-side state today: - Server populates `tracks[]` from `playlist_track.snapshot_*` since PR #32 (1.j.a). - Desktop emits the snapshots since PR #203 (1.j.b). - Pre-1.j.b clients keep their playlists invisible to the public preview (server filters `snapshot_title IS NOT NULL`); the fallback "Track list preview is not available yet" message kicks in for those, unchanged. New rendering: - A "X tracks · 32 min" sub-header (1 track / N tracks singularisation; "Xh YY" for > 60 min, two-digit minute pad). - Tracks list switches from `<ol>` to a flex-row layout with position number + title/artist + right-aligned duration column, divided by hairlines. `tabular-nums` so `5:21` and `12:03` line up the same pixel width on a font that defaults to proportional digits. `truncate` on the title cell prevents long titles from pushing the duration column off-screen. - The duration column is dropped per-row when the value is non- positive (pre-1.j.b snapshot without a duration), so we never print `0:00`. - The `<meta name="description">` head tag uses the same "X tracks · 32 min" helper as the rendered header so the Discord / iMessage / Slack embed reads the same as the open tab. New module `src/lib/share-format.ts` holds `formatDuration` + `formatTrackCountAndRuntime` so a unit test can exercise the formatters without piggybacking on the TanStack file route. **10 unit tests pass** covering sub-hour mm:ss, hour h:mm:ss, ms rounding, non-positive / NaN / Infinity guard, singular/plural, empty list, all-zero-duration fallback, > 60 min "Xh YY", single-digit remainder padding, negative-duration clamp. Total suite: 76/76 tests pass. Server-fn DTO doc updated to drop the "currently always empty" qualifier on `tracks`. Signed-off-by: InstaZDLL <github.105mh@8shield.net>

…stimates The breakdown uses the repository's own size labels and states plainly that the figures are estimates. Two refusals to group are recorded with their reason, since grouping was the instruction: compression stays alone rather than wait behind a several-hundred-line Rust project, and the pull request that changes the wire stays apart from the interface work that sits on the same screen — mixing the two is how the four defects of #203 went unseen. Two estimates moved after checking rather than assuming. The songs list needs a server route: issue #179 was closed on 2026-09-10 by renaming the endpoint to `/api/v2/songs/by-genre`, which made the contract honest without making the listing exist, so only `by-genre` and `random` remain. And the artist page's external source is probably already designed elsewhere — the plugins repository describes sandboxed WebAssembly components with a host-enforced HTTP allowlist, claims the same file runs on the server, and already carries two plugins that fetch remote media. The server knows nothing of it. The right RFC is likely the plugin host, not a Last.fm client. The design pass gains the evidence it was missing: `styles.css` runs two naming systems at once, roles beside appearance-named surfaces, and carries no spacing scale at all. That is what produces a screen with no rule about which token to reach for. Signed-off-by: InstaZDLL <github.105mh@8shield.net>

Four defects, one cause. Found by running a real server against a real library
rather than by reading code — none of them was reachable from the test suite as
it stood.
The cause
The types in
webapp/src/api.tsare hand-written assertions about the wire,and the mocks — e2e and unit alike — are built from those types rather than
from the server. A type that disagrees with the server is therefore invisible
to the whole suite: the mock confirms the client's account of the wire instead
of testing it. Four instances in one session, two of which take a page down.
Every mock this PR touches now answers the server's shape, and each fix
carries a test that fails without it.
What is fixed
1 — "Now playing" threw every time.
src/lyrics.rsrenames the wholeLyricsListstruct to camelCase, envelope included;api.tsdeclaredtrack_id/structured_lyrics. Sovalue?.structuredLyrics[0], writtenstructured_lyrics, threw on the first property.StructuredLyricsbeside itwas already correct — the inside was converted and the envelope forgotten. The
e2e mock sent the client's spelling, so it agreed.
2 —
undefined files of undefinedin the scan panel. The event stream senttwo shapes:
snapshotcarried aScanJobRecord,progresscarried thescanner's
ScanProgress. They agree on ten fields and disagree on three(
id/scan_id,total_files/total,processed_files/processed) — whichis why "164 added" was right and the line above it was not. The stream converts
through
ScanProgress::recordnow, andScanProgressis no longerSerialize, so the other shape cannot come back: there is no way left to putthat type on a wire. It also leaves the OpenAPI components, where it described
nothing any route answers.
3 — English prose in a French interface.⚠️ This changes the API shape.
GET /api/v2/scrobble-destinationspublished a finished English sentence inunavailable, which every client printed verbatim. It sends a case now —no_application_configuredorbrowser_journey_needs_https— and the wordingbelongs to whoever is doing the telling. An unrecognised case says "this server
did not say why" rather than going blank: a server is free to be newer than the
client reading it. Documented in the API guide.
4 — 127 artwork requests in 0.50 s, measured.
/api/v2/artwork/{hash}needs an
Authorizationheader, so<img src>cannot fetch it and everythumbnail costs a
fetchand an object URL. All of them started on mount, sothe covers below the fold were queued ahead of the ones being looked at and the
visible page filled last. An
IntersectionObserverwith 300px of lead asksonly for what is about to be seen. Where the browser has no observer, every
cover loads at once — exactly the previous behaviour.
How each fix was checked
Each one was removed again and its test watched to fall, on its own line:
structuredLyrics→structured_lyricsspec.ts:1677, the assertion on the wordsrecord()tests/scanner.rs:969,total_filesScanProgress: Serializeunsatisfiedspec.ts:1749, the assertion on the translated wordsspec.ts:879,hash-59asked for off screenTwo of these tests are new because the surface had none: no e2e fixture had
ever carried an
artwork_hash, so lazy or eager was untested either way, andnothing asserted that lyrics render at all — an empty sheet shows the same "no
lyrics" line under either spelling, so only an assertion on the words tells
them apart.
Gates:
cargo fmt --check,cargo clippy -D warnings,cargo test --all-features(all targets green),bun run typecheck,bun run lint,vitest119/119, Playwright 76/76 — built before each e2e run, sincevite previewservesdist/without building it.Deliberately not in this PR
useAsyncdoessetValue(null)beforerefetching, so the loading state reappears even when the answer is instant.
Real, but an interface judgement.
<img src>works and theHTTP cache serves between sessions. That is the deeper fix behind 4 and
deserves its own decision.
/openapi.jsonat build time. Theonly thing that would stop all four coming back. A tooling decision.
