Edge metadata (arrayBatchAll) was stamped at connection creation time and
went stale if the source node's batchMode was toggled later. Now
connectedInputs.ts reads batchMode directly from the source node, making
batch behavior always consistent with the current toggle state.

The batch textItems loop was only in executeWorkflow. regenerateNode and
executeSelectedNodes bypassed batch mode entirely, causing inconsistent
behavior when array nodes feed into generate nodes.
Extracted runBatchIfApplicable() into src/store/execution/batchExecution.ts
and wired it into all three execution entry points.

When dragging an audio connection and dropping to create a generateVideo
node, the audio input handle was not wired because the case was missing
from handleMenuSelect.

Removes the absolute-positioned header div and places the buttons

executeOutputGallery was reading gallery images from the stale node copy
captured during topological sort. When upstream batch execution pushed
images via appendOutputGalleryImage, the stale copy didn't reflect them,
so the gallery was overwritten with only the last generated image.

When batch mode is enabled on an array node, all parsed items are sent
through a single connection to a downstream generate node, which loops
through them sequentially. This eliminates the need to create separate
downstream nodes for each array item.

Replace JSON.parse(JSON.stringify(...)) in captureUndoSnapshot with
clonePreservingStrings — a custom deep-clone that creates new
object/array containers but returns string primitives by reference.
Since JS strings are immutable, snapshots safely share base64 blobs
instead of duplicating them. Reduces undo history memory from ~500MB
to ~12.5MB for workflows with 10MB of media data (97.5% reduction).

The handle dot color is set via data-handletype attribute selector in CSS.
Audio handles had no rule, so they fell back to the default appearance.

isImageInput() has permissive description heuristics (e.g. "data uri")
that false-positive on audio properties like audio_url whose description
mentions "base64 data URI". Reorder the checks so isAudioInput() — which
uses specific name patterns — runs first.

Add missing "audio-to-video" case to getCapabilityBadges() so the

The selected-node runner was treating audioInput and videoInput as no-ops,

The render guard at line 222 blocked all Gemini-provider models from
rendering parameters, including Veo models. Hoisted the isVeoModel
check to component scope and added the same exception used in the
fetch guard so Veo parameters (aspect ratio, duration, resolution)
display correctly.

- Fix redo shortcut by normalizing event.key to lowercase (Shift makes it "Z")
- Flush pendingDataSnapshot in undo/redo instead of discarding it, preserving
the pre-edit checkpoint so Cmd+Z doesn't skip states
- Recompute dimmedNodeIds after undo/redo to keep dimming in sync
- Set deleteCheckpointActive in removeEdge before clearStaleInputImages to
prevent split undo entries
- Wire videoInput in handleMenuSelect and isValidConnection for video connections
- Validate video MIME type against ACCEPTED_FORMATS whitelist instead of broad regex
- Use URL.createObjectURL(file) for metadata extraction instead of base64→Blob
- Add Shift+Y (Video Input) to keyboard shortcuts dialog
- Update executeNode JSDoc to include videoInput as data-source no-op
- Clear all *Ref/*Refs fields dynamically in clearNodeImageRefs

ModelParameters had an early return for all Gemini provider models,
skipping the API schema fetch. This was correct for Gemini image
models (which have built-in parameters) but prevented Veo video
models from loading their aspect ratio, duration, and resolution
parameters from the /api/models/[modelId] endpoint.
Closes#106

Veo models were excluded from ModelParameters rendering, hiding their
configurable properties. Remove the isVeoModel() guard so Veo models

React Flow v12's deleteElements fires onEdgesChange(remove) BEFORE
onNodesChange(remove), not after. The previous fix assumed the opposite
order, so the microtask-based nodeRemoveCheckpointActive flag was never
true when onEdgesChange ran.
Replace with deleteCheckpointActive — a bidirectional flag set by
whichever handler (edges or nodes) fires first. The second handler
skips its checkpoint. Use setTimeout(0) instead of Promise.resolve()
so the flag survives all microtasks in the current event-loop turn.
Also suppresses debounced undo snapshots from clearStaleInputImages
side effects during the same deletion cycle.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
When deleting a connected node, clearStaleInputImages calls updateNodeData
on target nodes to clear stale input images. Each updateNodeData call was
creating a debounced undo snapshot, resulting in 3-4 undos needed instead
of 1. Now updateNodeData skips undo tracking when nodeRemoveCheckpointActive
is true, since the node removal checkpoint already captured full pre-deletion state.

When deleting a node via the canvas (Delete key), React Flow fires
onNodesChange(remove) then onEdgesChange(remove) synchronously.
Previously this created two undo entries, requiring two undos and
leaving an intermediate state with orphaned edges.
Now onNodesChange sets a microtask-scoped flag that tells onEdgesChange
to skip its checkpoint, collapsing both into a single undo entry.
Added integration test verifying single-undo restores node + edges.

skippedNodeIds was in the Zustand store interface but never read by any
