+- Move CS Major autochess public game data out of `cs_autochess.py` and into
+  package data files under `jwebot_official_extensions/data/cs_autochess/`.
+  Player cards, coach cards, narrative fragments, shop/economy odds, draft
+  pacing, synergy thresholds, match formats, MR15/overtime settings, and
+  special event rewards are now data driven.
+- Add startup validation for the externalized data so missing fields,
+  duplicate card IDs, invalid schema versions, or an undersized narrative
+  library fail fast before the command engine runs.
+- Add regression coverage that verifies the JSON files are packaged, readable,
+  and consistent with the runtime card, coach, match-format, and narrative
+  inventories.
+- Add virtual coin transfers with `/转账 对方 金额` and `/transfer name amount`.
+  Transfers are single-transaction ledger updates, require the receiver to
+  initialize `/金币` first, reject self-transfers, and replay safely by event ID.
