 - CHORE/UX: free-form params (python nodes) get no suggestions, since there is no schema to key them off.
 - PERF/UI: `BrainView` runs 300 force-layout ticks synchronously inside a `useMemo`, so the graph is laid out on the render thread.
 - FEAT/UI: the brain is a band on a scrolling page now, so it neither pans nor zooms — the fit keeps the whole graph in view instead. An installation with enough flows to make the labels unreadable at that fit needs a way to open the graph larger.
+- CHORE/UI: React Flow measures a node's handle bounds out of the DOM once and never again, and in the brain that one measurement falls inside the graph's `scaleIn` entrance — so every `sourceX`/`targetX` it hands an edge there is the entrance's 4% short of the centre, permanently. `BrainEdge` takes both ends from the layout instead (position + radius). Any future view that mounts a canvas inside a transform and reads node internals meets the same thing.
+- CHORE/UI: a value passing lights the brain's connection blue for the pulse, but its two end dots only follow the slower falloff, so the flash stops where the line does.
 - CHORE/UI: `flow.css` drops the focus outline on every `.react-flow__node`. Brain neurons now answer `:focus-visible` with the same border colour as hover, but the flow editor's own nodes still have no visible keyboard focus.
