-- No-op placeholder. This migration's real content (sticker_sets.system_key
-- uniqueness) already applies via 20260901000006_sticker_set_system_key_unique
-- (identical SQL, applied earlier under our fork's own timestamp-based
-- migration numbering). The version number 181 itself must still exist as a
-- migration, though: internal/store/postgres/postgres.go's Migrate() calls
-- m.Migrate(phoneIdentityPredecessorVersion) (=181) to step a fresh database
-- to exactly this version before running the Go-side phone-identity
-- canonicalization pass, and golang-migrate requires that version to be a
-- real, reachable migration file. Do not reapply the sticker_sets change here
-- -- 20260901000006 already owns it, and repeating it would fail on an
-- already-unique index for any install that runs both.
