feat(artists): GET /api/artists/{id}/profile — public artist profile - #840
Conversation
Public, unauthenticated read backing the shareable artist page (recoupable/chat#1963): name, image, connected socials, and linked catalogs with song counts, in one call. - getArtistPublicProfile builds the response field-by-field as an allowlist; account_info's private fields (instruction, knowledges, label) stay out by construction. An account qualifies as an artist iff it appears as artist_id on at least one roster; anything else returns null. - The handler serves an identical 404 for malformed ids, unknown ids and non-artist accounts, so the endpoint cannot enumerate account ids. 200s carry Cache-Control: public, s-maxage=300, stale-while-revalidate=600. - countCatalogSongs counts per catalog with parallel head-count queries; a failed count reports 0 rather than failing the profile. Implements the contract in recoupable/docs#302.

📝 WalkthroughWalkthroughThe PR adds a dynamic public artist profile API. It supports CORS preflight, validates UUIDs, loads allowlisted profile data and catalog counts, and returns cached success or structured error responses. ChangesArtist profile API
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The new public profile endpoint can mask song-credit query failures as successful responses with incomplete catalog data, causing clients to receive misleading artist profiles instead of the documented server error; this should be fixed or explicitly accepted before merge. The endpoint also still lacks the repository-required parameter validation mechanism. Possibly related issues

Zod 4 z.string().uuid() validation semantics RFC 9562 accepted UUID versions and variants
💡 Result:
In Zod 4, the validation of UUIDs underwent significant changes to enforce stricter compliance with the RFC 9562 (which supersedes RFC 4122) specification [1][2][3]. Zod 4 Semantics and Validation The previous Zod 3 method, z.string.uuid, has been updated or replaced by the top-level z.uuid in Zod 4 [1][2]. This validator now strictly enforces RFC 9562 compliance, requiring specific bits for both the version and the variant [4][3]. If an input does not match this structure, validation fails [1][2]. For use cases requiring more permissive, "UUID-like" validation (e.g., any 8-4-4-4-12 hex string), Zod 4 provides z.guid [5][4][3]. RFC 9562 Compliance The RFC 9562 specification defines the structure of UUIDs, including specific requirements for versions and variants [6][7]. * Version: The version digit (the first character of the third group) must be between 1 and 8 [1][4][8]. * Variant: The variant bits (the first character of the fourth group) must be 8, 9, A, or B (corresponding to the 10xx binary pattern) [2][9][8]. * Special Values: Zod 4's strict implementation explicitly supports the Nil UUID (00000000-0000-0000-0000-000000000000) [8][10]. However, the Max UUID (ffffffff-ffff-ffff-ffff-ffffffffffff) is technically rejected by the standard strict regex because it does not conform to the version/variant requirements defined in the specification, despite being a recognized special value in RFC 9562 [8][10]. Zod 4 provides native support for specific UUID versions via z.uuid({ version: "vN" }) or dedicated helpers like z.uuidv4, z.uuidv6, and z.uuidv7 [5].

Use a dedicated Zod route-parameter validator.
UUID_RE accepts hexadecimal strings that do not satisfy UUID version and variant requirements. Add lib/artist/validateArtistProfileParams.ts with validateArtistProfileParams and a Zod UUID schema. Map validation failures to the existing notFound() response so malformed, unknown, and non-artist IDs remain indistinguishable.

Add an assertion such as `expect(eqMock).toHaveBeenCalledWith("catalog", "cat_1")` and `expect(eqMock).toHaveBeenCalledWith("catalog", "cat_2")` to lock the filter to the mapped id.</comment>

DRY - use the existing shared lib.

Fixed: the handler now uses the shared errorResponse for the 404s and the 500 — the local notFound helper is gone. One knock-on: errorResponse's house envelope is {status, error}, and the contract published {status, message}, so docs#303 is a one-field docs follow-up (new ArtistPublicProfileErrorResponse schema; the old $ref borrowed the socials endpoint's message-shaped schema). Verified live on the rebuilt preview: all three 404 paths return the identical {"status":"error","error":"Artist not found"}.

There was a problem hiding this comment.
Fixed: the socials and catalogs transforms are hoisted into named consts and the return is a flat literal of five fields.
Preview verification caught the linkage assumption wrong: account_catalogs links a catalog to its OWNER account, not its artists — Brauxelion's catalog links to the owner workspace, and the artist account has zero account_catalogs rows, so the profile returned catalogs: []. The artist-facing relationship is the songs graph: song_artists (the artist's credited ISRCs) into catalog_songs. selectSongIsrcsByArtist + selectCatalogsBySongs (chunked in-filter, deduped) replace selectAccountCatalogs in the profile composition. Verified against prod data: the artist's 26 credited ISRCs resolve to exactly one catalog.

Better than a rename — selectSongArtists already existed (added for attachCanonicalArtistToAccount) and its {artists: [id]} mode covers this exactly, chunking included. My file was a near-duplicate; deleted it and its test, with ISRC dedupe at the call site. Thanks for the catch.
…ngs, reuse selectSongArtists
- 404/500 bodies go through lib/networking/errorResponse, the house
{status, error} envelope (was a local helper emitting {status, message});
needs a one-line docs follow-up for the 404 example.
- getArtistPublicProfile hoists the socials/catalogs mapping into named
consts; the return is a flat literal.
- selectSongIsrcsByArtist deleted; the existing selectSongArtists({artists})
covers it, with ISRC dedupe at the call site.

Propagate query failures instead of returning an empty artist graph.
getArtistPublicProfile.ts consumes this result directly. A song_artists query failure is therefore indistinguishable from an artist with no credited songs. The public endpoint can return an incomplete profile instead of its shaped 500 response.
Throw a data-access error here and let the handler map it to the generic 500 response. Return [] only when the query succeeds with zero rows.
As per coding guidelines, handle errors gracefully. As per path instructions, use proper error handling.

One data note, not code
The artist's catalog is named "Brauxelion (re-materialized after delete)" — real prod data that will now render on a public page. Worth renaming the catalog before the chat page ships.

No account required to view. - app/artists/[id]/page.tsx renders from the unauthenticated GET /api/artists/{id}/profile endpoint via lib/recoup/getArtistProfile (null on 404 -> notFound(); ISR revalidate 300 to match the endpoint's s-maxage). generateMetadata emits title/description/OG image for unfurls. - components/ArtistProfile/*: PublicHeader (wordmark + Sign in + Get started), ArtistHero (image or initial tile, ARTIST label, display name, social chips), SocialChip + SocialIcon (inline stroke icons, globe fallback), CatalogsSection + CatalogCard (song count + updated month), PublicFooter. Shadow-as-border throughout per DESIGN.md. - Plain <img> for the artist image: sources are arbitrary hosts, which next/image's remotePatterns allowlist would reject. - lib/utils/formatMonthYear formats catalog updated_at as 'Aug 2026'. Consumes the contract in recoupable/docs#302, implemented in recoupable/api#840. * fix(artists): force-dynamic so an unknown artist returns a real 404 status Preview verification: notFound() rendered the 404 UI but the response committed as 200 with the streamed shell. A public page should give crawlers the true status; the profile fetch keeps its 300s ISR cache. * revert force-dynamic: the streamed shell pins the status regardless The root layout streams, so notFound() cannot change the HTTP status from any page-level setting; Next's designed fallback (404 UI + robots noindex, verified on the preview) is what protects crawlers. force-dynamic added cost without changing observable behavior; a comment records why. * fix(artists): public routes render without the app chrome or auto-login Preview verification: an anonymous visit to the public artist page opened the Privy login modal over the content, with the app sidebar alongside — useAutoLogin prompts every anonymous visitor and the root layout hard-wires the chrome. - lib/routes/isPublicRoute: the public-path predicate (TDD'd). - useAutoLogin skips public routes. - HideOnPublicRoutes gates Sidebar/Header/ArtistsSidebar in the layout — conditional mounting, not an early return inside the components, so rules-of-hooks holds. Review fix folded in: lib/utils/formatMonthYear moved to lib/dates (no generic utils folder). * fix(artists): wire HideOnPublicRoutes around the layout chrome Completes the previous commit, whose layout edit did not land: Sidebar, Header and ArtistsSidebar mount only on authed routes. * fix(artists): brand-correct social chip labels Naive capitalization rendered Tiktok/Youtube; a small map carries the brand casings (TikTok, YouTube, SoundCloud, X), everything else falls through to capitalize. * refactor(artists): review fixes — page fits the existing layout, no stray files - app/layout.tsx, Sidebar, Header, ArtistsSidebar restored to main: the public page renders within the existing app chrome, and only useAutoLogin's public-route exemption keeps the login modal from opening over it. HideOnPublicRoutes deleted. - Test screenshots removed from the tree; they live on the assets branch. * fix(artists): absolute social hrefs + clickable catalog cards Manual testing on the preview: social chips resolved relative — the socials table stores profile_url without a scheme (instagram.com/x), so the anchor navigated to a broken in-app path instead of the platform. ensureAbsoluteUrl (TDD'd) prefixes https:// when the scheme is missing; target=_blank was already set. Catalog cards are now links to the app's /catalogs/{id} page, with the design's hover elevation. * refactor(artists): drop the page-level header — the global layout owns sign-in The app chrome around the page already carries auth entry points in both states, so the page's own Sign in / Get started header was duplicate chrome.

The redundancy was the bug — three copies of "link artist to account", errors conflated with empty data, and check-then-insert with no visibility. - insertAccountArtistId: upsert on (account_id, artist_id) with ignoreDuplicates (constraint account_artist_ids_account_id_artist_id_key, database migration 20260708200000). Roster prechecks deleted at call sites. - linkSearchedArtistToAccount deleted; the valuation funnel's fallback now goes through resolveOrCreateArtist, the same resolver as POST /api/artists. - selectSongArtists throws on query error instead of returning null (the ??

Summary by cubic
Adds GET /api/artists/{id}/profile, a public endpoint for shareable artist pages. Fixes empty catalog results by resolving catalogs through credited songs rather than catalog ownership.
account_infoprivate fields are never serialized.artist_idon a roster; otherwise 404.song_artists→catalog_songs, ISRCs deduped and chunked); per-catalog song counts use parallel head-count queries; failures default to 0.Rollout
recoupable/docs#302(update the 404 example to{status,error}), deploy this endpoint, then merge the chat consumer (recoupable/chat#1963, row 3).Written for commit bea614c. Summary will update on new commits.
