-- ── module-uo's teardown ──────────────────────────────────────────────────
--
-- Destructive, and run ONLY by an explicit admin purge (MODULE_API.md §2.6).
-- Nothing on the boot path ever executes this file — uninstalling a module
-- leaves its data alone, and removing the data is a separate decision an
-- operator has to make on purpose.
--
-- It exists because `schema.sql` does. A module that can create tables and
-- cannot drop them leaves an operator with orphaned data and no supported way
-- to remove it, which is why core refuses to load a module that declares one
-- without the other.
--
-- **The order is the reverse of creation, and that is load-bearing**: two of
-- these tables carry a foreign key into core's `users`, and several reference
-- each other. Dropping a parent before its children fails on the constraint,
-- and a purge that fails halfway is worse than one that does not run — it
-- leaves exactly the orphaned data this file exists to remove. `IF EXISTS` on
-- every line so a partially-installed module still tears down cleanly.
--
-- What is NOT here, deliberately: rows this module wrote into core's tables.
-- `notification_subs` rows for `shard.*` streams and `announce_job_legs` rows
-- with leg `towncrier` belong to core's tables, and a module does not delete
-- from those — core prunes them when it drops the registrations, which it can
-- do because it knows which registrant owned what. The two `settings` rows
-- schema.sql seeds (`game_account_signup`, `uo_link_protocol_3_migrated`) are
-- the same case with an extra reason: the second is a one-shot MIGRATION
-- marker, and deleting it would re-arm a protocol bump against tables this
-- file has just dropped.
