The CLI's `fusion_electron_run` help points here via its `note` field. No rebuild required.++## Traps that cost a board (2026-10-08, the TPS54202 buck)++- **DELETE at a point can delete a whole part.** In the board editor a point that lands on a part's own tPlace artwork picks the PART, and DELETE removes the element with its connections (J4 and MP4 went this way during a silkscreen cleanup). Delete only at a plain text's or a smashed name's exact origin (that removes just the text), never on a line, and compare the element count before and after.+- **CHANGE at a point does not land** in Fusion's board editor (CHANGE LAYER 51 (x y), CHANGE SIZE (x y)), and neither does CHANGE by name ('R1>NAME'). Move and rotate by name (MOVE 'R1>NAME' (x y), ROTATE =R90 'R1>NAME') inside a SCRIPT; remove a text with DELETE at its origin.+- **`fusion_board_source` saves a new cloud version** each time it reads the board, so an edit is never left unsaved and closing without saving does not undo it. To undo, promote the earlier version: `fusion_aps_versions {query}`, then in `fusion_run_modeling_script`: `app.data.findFileById(<lineage urn>).versions` and `.promote()` on the clean one; close the open copy with `fusion_close_document {name, save:false}` and reopen.+- **`fusion_close_document` with no name closes the ACTIVE document.** Always pass `{name, save:false}` (or `save:true`).+- **Never close the bridge's "ADOM" panel window with a window-close call** (`desktop_close_window`): it closes Fusion with every open document. Click the panel's own Close button, or leave it; it is parked small at the lower right.+- **A SCRIPT stops at a dialog.** When a script's command raises a Fusion dialog, the rest is refused with "dialog is up"; check the reply and the board after every script.
