From 39aff2e18efd0e7b7a4a9fcd56f41700a88e262d Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 27 Aug 2026 19:38:48 +0000 Subject: [PATCH] Fix five high-severity defects found in review All five reproduced before the change and verified after, each with a test that fails without its fix. 1. A gesture never ended when the button was released off the canvas. mousedown, mousemove and mouseup were all bound to the svg, so letting go over the properties panel never reached _onUp: the gesture stayed live and the next move dragged or panned with no button held. Space+drag was the worst of them, panning the whole canvas under a free cursor, and Escape cleared only three of the nine gesture fields so there was no way out. Because _changed() lives inside _onUp, the move never reached undo or autosave either. Window-level listeners now finish a gesture wherever it ends, guarded so the svg handlers never run twice for one event, and Escape releases everything and commits what moved. Measured: a node went 520,440 -> 300,480 on a buttonless move, and pan 60,0 -> -200,-150. 2. Chip rows never committed. A chip fires no change event, so switching rate mode or gate routing reached the model but not the undo stack or autosave: reload and it was back, and undo instead reverted the previous genuine edit while dropping the switch for good. 3. _refreshResourceCount wrote the selected node's live count into the first number input of whichever diagram-rail panel was open, because a rail feature borrows the panel without clearing the node selection. A parameter set to 7 displayed 5 and counted up with the pool; one edit committed the wrong number. It also reached Design tests, which the report had not mentioned. 4. Copy share link pinned the tab to that snapshot. The hash outranks autosave in _initDiagram and nothing ever cleared it, so an hour of later work vanished on reload with an empty undo stack. The same trap caught anyone opening someone else's link and then working in that tab. The link now goes only to the clipboard, and a diagram adopted from a hash is written to autosave and the hash dropped, so a reload restores what is on screen. Embed mode keeps its hash and never touches the host's autosave. 5. A limited source lost its stock color through the .econ round-trip, leaving grey, so any outgoing colorFilter matched nothing: a 10-step run moved 20 units before and none after. The guard that caused it is load-bearing, since `limited` can appear later on the line and an unlimited source has its stock zeroed afterwards, so the color is stashed and applied once the line is read. The fallback mirrors the serializer, which emits `of X` only for a non-default color: reading an absent `of` as the node's resourceColor invented a color the file never held, which the kitchen-sink round-trip caught.
