Name	Kind	Summary
`terrain_cell_changed`	Signal	Fires on every GridMap cell edit made through this service (paint, replace, or erase — erase reports [constant GridMap.INVALID_CELL_ITEM]). Games can connect to re-validate placed objects after terrain edits; the policy stays with the game, placement-time validation remains authoritative.
`fail_on_identical_repaint`	Property	When true, repainting identical terrain fails loudly (legacy behavior). Default false: identical repaints read as valid placements that changed nothing — silent, with PlacementReport.placed left null and a "No tiles placed" note for logs. Rule rejections and config errors always fail loudly regardless of this flag.
