The floor logic looks right to me, and the tests check the right direction: the floor never goes above the measured width.
Same gap as on #887, just on the width side. workflow_ops.add_node doesn't pass n_multiline, so a multiline node gets saved at width 270 instead of 400, and the next call places against 270. The #887 fix covers both. I'll approve once that lands.

… the node Review was right, and the bug was worse than a missed argument. add_node calls estimate_size a SECOND time and writes that result into the node's `size`. That saved size is what every later collision check reads, so the planner was correct and the persisted state was not: a batch placed cleanly, then the next call placed a node against a record of the first that was 142px too short. Both callers now derive the count through one helper, layout.count_multiline, which was the reviewer's preferred shape. Having two call sites each compute it their own way is what allowed them to disagree in the first place. Also takes the nit: _widgets_height clamps n_multiline to n_widgets. The old test asserted that a one-widget node could be charged five multiline areas, codifying a 700px over-measure as intended. It only arises from a bad catalog or a caller bug and silently over-measuring hides both. New tests assert the SAVED artefact rather than the planner's return value -- every existing layout test exercised assign_positions, which is exactly why this got through. Two are verified red with the add_node argument removed. NOT included: the reviewer's two-batches-then-one-more overlap repro. On this branch the height is fixed but width is still text-derived (249.9 for CLIPTextEncode), so the third node lands clear and the case cannot go red -- he reproduced it at the #888 head, where the 400px width floor makes it overlap. It goes there. Asserting it here would have passed for the wrong reason, which I only caught by checking that it failed without the fix.

Use widget_order_default when planning fresh nodes.
assign_positions uses graph.widget_order, which includes only the dynamic-combo selector. add_node uses graph.widget_order_default, which expands the first option for a fresh node.
A fresh dynamic-combo node can therefore be planned with fewer widget rows than the persisted node. The planner uses that smaller rectangle for batch spacing, while add_node persists the larger rectangle at the same position. Later nodes can overlap.
The mismatch is caused by the extra widget rows. The current count_multiline implementation scans only top-level inputs, so the claimed 270px-versus-400px floor difference does not apply to a nested dynamic-combo sub-widget.
Proposed fix
- widget_names = tuple(graph.widget_order(spec["class_type"]))
+ widget_names = tuple(graph.widget_order_default(spec["class_type"]))Add a regression that compares planned and persisted sizes for a fresh dynamic-combo node with a nested multiline sub-widget.

…ender The width model under-estimates, and under-estimating width is what produces the overlap users report: the placer puts the next column a node-width away and the real node reaches past it. LiteGraph's own formula is NODE_WIDTH * (1.5 if widgets else 1.0) = 210, which no widget-bearing node actually renders at. Measured across 27 classes in a real browser: every node carrying a widget renders at 270 or wider, every node carrying a MULTILINE widget at 400 or wider. Fourteen of fourteen non-multiline widget classes land at exactly 270 when their content is narrower, and seven of seven multiline classes at exactly 400 -- the shape of a floor, not a fixed width. KSamplerAdvanced 312, ControlNetApply 317.9 and CheckpointLoader 396.9 exceed it on content, which is what confirms it. Before this, on the eight classes in the release fixtures, five were under-estimated: CLIPTextEncode by 150, EmptyLatentImage and CheckpointLoaderSimple by 60, LatentUpscale by 48, SaveImage by 40. After, zero are. The three over-estimates (KSampler +19, ConditioningCombine +48, VAEDecode +6) are left alone: over-spacing wastes canvas, which nobody has filed. Effect on the release fixtures, scoring placer output against measured width AND height: txt2img 16,123 -> 0 px^2, four-prompts 0 -> 0. #886 and #887 fixed the height term; this is the width term of the same defect, and txt2img needs all three. Known over-estimate, accepted: Note and MarkdownNote carry a multiline widget but render at 140 because they are annotation nodes with no slots. They get floored to 400 and will be over-spaced. Left deliberately -- the direction argument above applies, and special-casing them on "no inputs and no outputs" is a guess I have not measured. 17 parametrized cases assert the floor never exceeds what a class renders, plus four behavioural tests. All verified red on the parent.
…roduces Two multiline nodes in one batch, then one more in a second call. The second call measures against the SAVED sizes, so under-measuring places the new node inside the first. This test belongs here rather than on the height PR. With a text-derived width (249.9 for CLIPTextEncode) the third node lands at x=369.9 and clears -- the case passes for the wrong reason. At the 400px floor the first node truly spans 40..440 and the overlap is real, which is why the reviewer saw it at this head. Scored against the size the node TRULY renders at, not the size that was saved. Scoring against the saved size is how the bug hides: an under-measured node "does not overlap" precisely because the record of it is too small. That is the same error that made the first release-gate numbers wrong, so the test carries an explicit guard that the floor is in effect before it claims to mean anything. Verified red with the width floor reverted, green with it.

Stacked on #887. The third and last term of the same defect — and txt2img needs all three.
Why
Under-estimating width is what produces the overlap users report: the placer puts the next column a node-width away, and the real node reaches past it.
LiteGraph's own formula is
NODE_WIDTH * (1.5 if widgets else 1.0)= 210, which no widget-bearing node actually renders at. Measured across 27 classes in a real browser:KSamplerAdvanced312,ControlNetApply317.9,CheckpointLoader396.9 exceed it on content, which is what confirms this is a floor and not a fixed widthI originally read the first five samples as "widget nodes are exactly 270". That was wrong — it held by luck on a small sample, and the next nine classes disproved it. The floor is the rule that survives all 27.
Effect
On the eight classes in the release fixtures, five were under-estimated:
CLIPTextEncodeby 150,EmptyLatentImageandCheckpointLoaderSimpleby 60,LatentUpscaleby 48,SaveImageby 40. After this, zero are.Scoring placer output against measured width and height:
#886 and #887 fixed the height term. This is the width term of the same root cause — multiline widgets modelled as ordinary rows — showing up in the other axis. txt2img does not reach zero without all three.
What is deliberately not fixed
The three over-estimates (
KSampler+19,ConditioningCombine+48,VAEDecode+6) are left alone. Over-spacing wastes canvas; nobody has ever filed that. Under-spacing is the bug.NoteandMarkdownNotecarry a multiline widget but render at 140, because they are annotation nodes with no slots. They get floored to 400 and will be over-spaced. Left deliberately: the direction argument above applies, and special-casing them on "no inputs and no outputs" is a guess I have not measured.Tests
17 parametrized cases asserting the floor never exceeds what a class renders (a floor above the rendered width would over-space every node of that shape), plus four behavioural tests covering each branch. All verified red on the parent; 62 pass in the layout suite.
