Row 1 of recoupable/chat#1968. Approved design: Artist Profile V2 canvas.

Extends GET /api/artists/{id}/profile additively:

  • ArtistPublicProfileCatalog gains songs[] — new ArtistPublicProfileSong schema: isrc, name, album (nullable), artwork_url (nullable, Apple Music), plays (latest capture, staleness documented), est_value_usd (mid of the published Recoup valuation model). Sorted by plays desc, capped at the top 50; song_count documented as possibly exceeding songs.length.
  • The response gains nullable valuation {low, mid, high} (new ArtistPublicProfileValuation schema) — the band across all credited songs.

No v1 field changes; both new response fields are additive. releases.json parses after anchored additive edits.

Merge order

First of the chat#1968 fleet: docs → database → api → chat.


Summary by cubic

Extends GET /api/artists/{id}/profile to power Artist Profile V2: each catalog now returns its top songs and the response includes a nullable catalog valuation band. Previously catalogs exposed counts only and no valuation; now each catalog includes up to 50 songs sorted by plays and the response includes low/mid/high valuation.

  • Review notes:
    • OpenAPI: adds songs[] to ArtistPublicProfileCatalog (ArtistPublicProfileSong: isrc, name, album nullable, artwork_url nullable, plays, est_value_usd) and adds valuation (ArtistPublicProfileValuation: low, mid, high; nullable) to the root profile.
    • Behavior: songs sorted by plays desc and capped at 50; song_count may exceed songs.length; valuation null when no measured songs exist.
    • Compatibility/migration: additive only; no v1 field changes. Clients must not assume songs.length equals song_count.

Written for commit 5bb3799. Summary will update on new commits.

Summary by CodeRabbit

  • Documentation
    • Updated the public artist profile API specification to include valuation details with low, mid, and high estimates.
    • Added song-level information to artist catalogs, including identifiers, titles, albums, artwork, play counts, and estimated values.
    • Documented the new song and valuation response structures, including nullable valuation data.

…rk and $ estimates

Contract for the artist page V2 (recoupable/chat#1968): each catalog carries
its songs (isrc, name, album, artwork_url, plays, est_value_usd), sorted by
plays and capped at the top 50, and the response gains a nullable valuation
band from the published Recoup model. Additive; v1 fields unchanged.

📝 Walkthrough

Walkthrough

The OpenAPI document expands public artist profiles with nullable catalog valuation data and per-catalog song details. It adds schemas for song metadata and low, mid, and high valuation amounts.

Changes

Artist profile schema expansion

Layer / File(s) Summary
Artist profile response and catalog contract
api-reference/openapi/releases.json
ArtistPublicProfileResponse now requires nullable valuation. ArtistPublicProfileCatalog now requires songs. New schemas define song metadata, estimated song value, and catalog valuation bands.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 5bb37

The API documentation currently does not correctly represent nullable valuations and does not enforce the documented 50-song response cap, which can cause client validation or generated-model mismatches. Merge should wait for these schema corrections.

Represent nullable valuation with a 3.1 null union.

releases.json declares OpenAPI 3.1.0, where nullable is not a JSON Schema keyword. The required valuation property therefore does not accept null, despite its documented contract. Use oneOf with ArtistPublicProfileValuation and { "type": "null" }, as in CatalogListItem.valuation.

Preview verification — local Mintlify dev server

Ran npx mintlify@latest dev on docs/artist-profile-v2-songs @ 5bb3799 and drove it with Chrome DevTools MCP at 1440×900. All checks against the rendered site.

Documented vs actual

# Check Expected Actual
1 Generated 200 example songs array + valuation band render from the spec Example carries catalogs[].songs[] with all six fields (isrc: "QZTPX2553097", name, album, artwork_url, plays, est_value_usd) and the top-level valuation {low, mid, high}
2 catalogs.songs field docs Cap + caveat "sorted by plays descending and capped at the top 50 — song_count reflects the full catalog and may exceed songs.length" renders on the field
3 Nested song field docs All six children with descriptions catalogs.songs.{isrc,name,album,artwork_url,plays,est_value_usd} all render behind the child-attributes disclosure — ISRC with the real example, artwork nullable ("or null when artwork has not been resolved yet"), plays staleness ("Captures are periodic, so this can lag the live number"), est_value_usd naming the published model
4 valuation field docs Nullable band + children Top-level field renders object | null with the model description; low/mid/high children each documented
5 v1 intact No changes to existing fields id/name/image/socials docs and the 404 {status, error} example unchanged; cURL still auth-free
6 Links + console Clean All internal links 200; 0 console errors
7 Spec integrity parses, additive releases.json parses; diff is purely additive (4 anchored inserts)

Screenshots

1. Field docs + generated example together — the catalogs.songs children on the left, the full songs array + valuation band in the 200 example on the right:

Songs docs and example

2. The catalogs.songs field — cap text and the expanded child attributes:

Songs field docs

Test-method note (no action needed)

The nested field docs live behind Mintlify's child-attribute disclosures, which collapse on tab switches and mis-toggle under bulk clicking — the verification expands them sequentially. Worth knowing for future doc passes on deeply nested schemas.

…rk and $ estimates (#842)

* feat(artists): profile v2 — per-catalog songs with plays, ISRC, artwork and $ estimates

Implements the extended contract in recoupable/docs#304 (chat#1968): each
catalog in GET /api/artists/{id}/profile carries its songs (isrc, name,
album, artwork_url, plays, est_value_usd), sorted by plays and capped at the
top 50, and the response gains a nullable valuation band.

- selectLatestSongPlays: latest spotify platform_displayed_play_count per
  ISRC via the existing measurements selector, chunked; failures degrade to
  no data, never a failed page.
- resolveSongArtwork + updateSongArtworkUrl: fetch-on-miss write-through
  from the Apple batch ISRC lookup to songs.artwork_url (database#58).
  Apple failure or a write failure degrades to null artwork.
- buildProfileSongs: pure composition — grouping, sort, cap, and every
  dollar delegated to computeValuationBand (per-song mid; artist-level band
  across all plays with the earliest release date across catalogs; null
  when nothing is measured). No copied constants.
- selectCatalogSongIsrcs: (catalog, song) grouping rows, chunked.
- getArtistPublicProfile orchestrates; allowlist construction unchanged.

* fix: resolve Apple artwork {w}x{h} template before persisting

Apple returns artwork.url as a size template; the profile stored and served
it verbatim, so artwork_url was not fetchable. resolveAppleArtworkUrl
substitutes a concrete 296x296 before write-through (TDD red->green).

* review: KISS renames — selectCatalogSongs, generic updateSong, plays composition to lib/songs

- lib/supabase/catalog_songs/selectCatalogSongs.ts (was selectCatalogSongIsrcs)
- lib/supabase/songs/updateSong.ts takes a column map, callers pass { artwork_url }
- selectLatestSongPlays composes over selectSongMeasurements, so it lives in
  lib/songs, not lib/supabase

* style: collapse import onto one line (prettier)

* review: simple supabase libs — chunking to lib/songs, typed updateSong

- selectCatalogSongs is now a plain .in() query; the 200-ISRC chunking
  lives in lib/songs/getCatalogSongs (TDD red->green)
- songs.artwork_url added to the generated types (database#58 is applied
  to prod), so updateSong takes TablesUpdate<"songs"> with no cast and
  the profile reads song.artwork_url directly

…lays and $ estimates (#1970)

* feat(artists): v2 songs UI — Spotify-style list with artwork, ISRC, plays and $ estimates

The V2 page per the approved canvas (#1968): the catalog
card grid becomes a SONGS section — one block per catalog with
column-labeled rows (# / artwork / title+ISRC / album / plays / est. value),
top 5 with a Show-all expander, and the hero gains the est. catalog value
band. Mobile stacks $ over compact plays per the Mobile artboard.

- SongsSection (client, expander state) + SongRow + ValuationBadge replace
  CatalogsSection/CatalogCard; valuation CTA stays below the list.
- Artwork <img> with a note-glyph tile when artwork_url is null.
- formatCompactNumber + formatUsdEstimate/formatUsdBand (TDD'd) render the
  counts and money; all values come from the api, no client math.
- getArtistProfile types extended for songs[] and the valuation band.

Consumes recoupable/docs#304 / recoupable/api#842.

* fix: pin compact-currency fraction digits across ICU builds

CI's Node/ICU renders $84.0K where local renders $84K; declare
minimumFractionDigits + trailingZeroDisplay so both agree.
