The cast-failure reporter skipped arms of 1.12.1's errorId chain and its pet text. A move also cancelled a cast from the wire word, not from the press.
- The player's chain now runs whole, in the bytes' order (`0x6e1aab`-`0x6e1c5f`). Every id, 0x2c included, formats through its key's live global (`0x4967d7`), and an empty line is still logged.
- Spells aimed at the pet show their `_PET` text (`0x6e1b1b`). An item-target refusal reads `ERR_INVALID_ITEM_TARGET`.
- The full-power line names the player's own power (`0x6e211f`). The pet's handler stays silent when it has no record or finds no name.
- A movement command press cancels the cast whoever drives (`0x515090`). Only a channel needs the player as the mover (`0x515180`).
Tests pin each arm, the pet lines and the cancel through the controller.
