Nothing listened to the player's item objects after they changed. Action and trade slots diffed snapshots, so an addon missed restacks, enchants and destroys.
- **The seam.** `item_watch` emits one notice per reference handler run, in wire order. The handlers are destroy `0x5d8660`, stack `0x5d9400`, charges, entry, enchant `0x5d9a90`, record `0x5d8440`, seats `0x4f8db0`/`0x4f90d0`/`0x4f8ec0` and visible items `0x5dee30`.
- **Action bar.** Each notice recounts every item slot holding the entry and fires `ACTIONBAR_SLOT_CHANGED`, with no change test (`0x4e5c70`, 16 callers). Arrival recounts quietly, then fires slot 0 (`0x5dea50`). The per-frame poll is gone.
- **Trade.** Our slot re-sends or clears its item and fires `TRADE_PLAYER_ITEM_CHANGED` (`0x4bfb10`, `0x4bfb60`). Slot 7's enchant spell signals its side and names the enchantment (`0x4bf2b0`). `ClickTradeButton` refuses bound, quest and bag items (`0x4bfeb5`).
Tests cover every watcher, consumer order and refusal.
