+-- of 1779500000000 (2026-05-23). drizzle-orm@0.38.4
+-- (pg-core/dialect.js#migrate) only applies a migration when
+-- `migration.folderMillis > lastDbMigration.created_at`, so on prod —
+-- whose last applied entry was 0033 at created_at=1779500000000 — 0034
+-- was silently skipped, leaving `pets.temperament_score` (and friends)
+-- missing. The migrate Job still exits 0 ("migrations applied
+-- successfully!") because the journal high watermark *was* advanced by
+-- 0038, but no schema change ever ran for 0034. Seed/reset then crash on:
+--   PostgresError: column "temperament_score" does not exist (42703)
+--
+-- Same pattern as GRO-1999 (0037 → 0038): do NOT modify 0034 in-place
+-- (UAT/dev have already applied it via their lower watermarks). Add a
+-- new idempotent migration with a monotonic `when` instead so existing
+-- DBs apply it cleanly and fresh DBs are a no-op-after-no-op.

+-- Migration: 0040_register_missing_coat_type_values.sql
+-- GRO-2033: re-register the 'short' / 'medium' / 'silky' coat_type enum
+-- values that 0036 added with `when` = 1751480000000 — *below* the 0033
+-- high-water mark of 1779500000000. drizzle-orm@0.38.4
+-- (pg-core/dialect.js#migrate) silently skipped 0036 on prod for the same
+-- reason it skipped 0034 (see 0039). 0036 itself was idempotent
+-- (`ADD VALUE IF NOT EXISTS`), but its journal entry was never applied,
+-- so the values are not in the prod enum.
+--
+-- Same pattern as GRO-1999 (0037 → 0038) and 0039: do NOT modify 0036 in
+-- place. Add a new entry with a monotonic `when` (1780000000002) so
+-- existing prod re-applies it; UAT/dev are a safe no-op because the
+-- statements are `IF NOT EXISTS` and the values are already there.
+--
+-- Postgres restriction: `ALTER TYPE ... ADD VALUE` cannot run inside a
+-- transaction block, so we emit individual auto-commit DDL statements
+-- (no BEGIN/COMMIT). drizzle-kit migrate executes inside a tx; with
+-- `ADD VALUE IF NOT EXISTS` Postgres is permissive and treats it as a
+-- regular DDL statement that *can* run inside a tx in 9.6+ when no new
+-- value is actually added. If you ever rename this to add a value that
+-- doesn't exist on every target DB, lift it out of the journal
+-- transaction (single-statement file) — see GRO-1999 commit 423d4bf.
