HOTFIX for v2026.05.15.0. R3 added deep_cuts/rediscover/new_for_you/ on_this_day/first_listens producers + registry entries but not their system_variant values to the playlists_kind_variant_consistent / playlists_seed_consistent CHECK constraints (0021's whitelist). insertSystemPlaylist for any new mix → SQLSTATE 23514, and since BuildSystemPlaylists is one all-or-nothing txn that aborts the ENTIRE build — For-You/Discover refresh 500s and the daily lazy build fails too. System playlists are fully broken in prod. Migration 0028 drops + re-adds both constraints with all five new seedless variants (mirrors the 0021 drop-and-readd pattern). CHECK-only — sqlc/dbq unaffected (regen produced no drift). Bumps to 2026.5.15+7 for the v2026.05.15.1 patch release. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

-- #411 R3 bugfix: the five discovery mixes (deep_cuts, rediscover,
|
|
-- new_for_you, on_this_day, first_listens) were added as producers +
|
|
-- registry entries but their system_variant values were never added
|
|
-- to the two playlists CHECK constraints. Result: insertSystemPlaylist
|
|
-- for any new mix fails with playlists_kind_variant_consistent
|
|
-- (SQLSTATE 23514), which — because BuildSystemPlaylists is one
|
|
-- all-or-nothing transaction — aborts the WHOLE build, so For-You /
|
|
-- Discover refresh 500s and the lazy daily build fails too.
|
|
--
|
|
-- All five are seedless (like for_you/discover): seed_artist_id IS
|
|
-- NULL. Drop + re-add both constraints with the expanded set, same
|
|
-- pattern as 0021_discover_variant (Postgres has no ALTER CONSTRAINT
|
|
-- for CHECK).
