fix(roster): one idempotent attach path for valuation claims - #841
Conversation
The 2026-08-18 incident: a funnel signup's catalog claim left an empty /artists roster because both roster-attach layers failed silently. 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 ?? [] conflation turned failed queries into "no links"); deleteArtist keeps its fail-closed behavior via its own catch. - attachCanonicalArtistToAccount no longer swallows; createSnapshotCatalog no longer attaches (returns the measured ISRCs instead) — each surface owns its attach policy at one catch site: createCatalogHandler stays best-effort, runValuationHandler carries any attach error into the valuation lead alert. - captureValuationLead: Roster line in the Telegram message — attached ✓ / ATTACH FAILED — <error> / nothing attached. Net -95 LOC. Full suite 4566 tests green; tsc noEmit introduces no new errors over baseline. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

📝 WalkthroughWalkthroughThe PR replaces lookup-before-insert roster linking with idempotent upserts. Catalog resolution returns measured ISRCs and delegates roster attachment. Valuation performs explicit artist attachment and reports failures. Artist deletion now fails closed when dependency lookup fails. ChangesRoster and valuation flow
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR centralizes roster linking through an idempotent upsert and reports attach failures in valuation alerts. It is mergeable with owner awareness because concurrent pin writes can leave a new roster link with the wrong pin, and alert messages may expose raw backend or application error details.

Not applying: the create-race (two concurrent first-ever valuations of the same brand-new artist both observing no canonical) is pre-existing behavior of resolveOrCreateArtist, unchanged by this PR — the deleted duplicate had the identical race. chat#1889 deliberately placed dedup at creation, and chat#1965 explicitly scopes out further hardening until the new alert proves recurrence (YAGNI). The alert line this PR adds is what makes any such duplicate same-hour visible instead of silent.

Not applying — same finding CodeRabbit raised and withdrew on the thread at runValuationHandler.ts:149: surfacing error.message here is chat#1965's explicit design decision. The target is the internal team channel (already carries the lead's email + Attio link), the possible messages are our own lib throws wrapping Postgres diagnostics, and a sanitized code would recreate the incident's failure mode (the real error rotting in rotated runtime logs).

Not applying: the window is a select→insert race inside setAccountArtistPin where the same pair is being linked concurrently on another surface, in the same milliseconds a user pins from the org view. Before this PR the same race threw 23505 (constraint live since 2026-07-08) → 500; now the pin is a silent no-op and a re-tap fixes it — strictly less user-visible breakage. The alternative (DO UPDATE semantics on the shared upsert, or a second pin-specific writer) either churns every link row's updated_at or reintroduces a second link implementation — the redundancy chat#1965 exists to delete. Revisit if a real pin-loss report ever shows up.

Not applying: a null artist from the resolver is not always a failure. On the link-existing path the roster link has already succeeded (upsert) when selectAccountWithSocials returns null — labeling that ATTACH FAILED would be wrong on the alert. Both remaining states prompt the identical on-call action (open the account, one POST /api/artists from repair), and the incident's gap was invisibility, not taxonomy — 'Roster: nothing attached' makes the empty-roster case loud, which is the fix's actual claim.

Confirmed real — this caller landed in #840 after this branch's point and my caller sweep ran against a stale tree, so it kept the null-contract assumption. Fixed in 2af5d96: the songs-graph lookup is wrapped so a query error costs the catalog list, never the whole unauthenticated page (RED test first: mocked rejection → profile still returned with catalogs: []).

Fixed in fe838c5 — renamed to upsertAccountArtistId (file + function) across all call sites and tests, matching the upsertSongs convention.
- insertAccountArtistId -> upsertAccountArtistId (file + function): the implementation is an upsert, so the name follows the supabase lib convention (review feedback, cf. upsertSongs). - Extract resolveClaimedCatalog from createCatalogHandler (93 lines, back under the 100-line file limit). - Drop the vacuous conflict test in upsertAccountArtistId.test (asserted nothing beyond the default mock); add the both-null "nothing attached" path test to runValuationHandler.

In `@lib/artists/setAccountArtistPin.ts`:
- Around line 25-32: Update setAccountArtistPin to ensure the missing-row path
always applies the requested pinned value when a concurrent roster link creates
the relationship: use a dedicated atomic conflict-update operation, or follow
the ignored insert with an update that sets pinned. Add a concurrency test
covering simultaneous relationship creation and pinning.

lib/catalog/resolveClaimedCatalog.ts, a failed measurement query during re-claim is treated as an empty ISRC set, allowing the request to succeed while leaving the roster link unhealed; expose measurement-read errors separately so the caller can handle the failure explicitly.

Final preview verification — latest commit (2026-08-18)Re-ran the matrix against the deployment built from the PR head

Summary by cubic
Unifies roster attach for valuation claims behind a single idempotent upsert and makes failures visible. Previously, check-then-insert paths and swallowed errors produced silent empty-roster claims; now a
(account_id, artist_id)upsert handles idempotency, callers choose failure policy, and the public artist page degrades to an empty catalog list instead of 500 on songs-graph errors.Replace
insertAccountArtistIdwithupsertAccountArtistId(upserts on(account_id, artist_id)withignoreDuplicates); delete all roster prechecks.setAccountArtistPinstill selects to distinguish update vs insert-with-pin.Remove valuation-only
