-- Yumi Game King: canonical GAME_CONSUME_GOLD -> draw chances, deterministic ranking and settlement.
--
-- Performance review:
-- 1. The event path first resolves the very small set of enabled activities by
--    (sys_origin, enabled, start_time, end_time), then inserts a unique activity/event ledger row
--    and updates one aggregate primary key. It never scans wallet shards or arbitrary expenses.
-- 2. Ranking reads the materialized aggregate through
--    (activity_id, total_consumed DESC, consume_reached_time ASC, user_id ASC); settlement freezes
--    only Top 30 and does not GROUP BY the append-only ledger.
-- 3. Draw idempotency, settlement idempotency, finite-stock reservation and reward delivery claims
--    all use primary/unique keys. Unlimited stock (-1) is not updated and therefore avoids a hot row.
-- 4. Backfill binds sys_origin + GAME_CONSUME_GOLD and keysets by (occurred_at,id) through the added
--    index. The public lastId is resolved to its scoped occurred_at before each page, preserving the
--    lastId-only contract without sorting/rescanning the whole activity window.
-- 5. The activity tables are empty, but the backfill index targets the existing production
--    task_center_event_archive_outbox (about 35 million rows / 50 GiB at review time). Treat that ALTER
--    as an independent online DDL: run it before the application rollout, monitor metadata-lock waits,
--    temporary disk usage and replica lag until completion, and do not hide it inside a service restart.
-- 6. The ALTER explicitly requires ALGORITHM=INPLACE and LOCK=NONE. If the target MySQL version or table
--    state cannot honor those guarantees, the migration must fail instead of silently falling back to a
--    table-copy or write-blocking algorithm. It performs no UPDATE/DELETE/backfill.
-- 7. The one-row-per-sysOrigin scope lock is touched only by admin enable/save transactions; it keeps
--    concurrent overlap checks correct without serializing the high-volume game event path.
