regenerateNode was not creating an AbortController or passing a signal
to _buildExecutionContext, so stopWorkflow() couldn't cancel in-progress
batch iterations. Now creates and stores _abortController on entry and
clears it on all exit paths (early returns, success, and error).

copySelectedNodes, pasteNodes, and AI captureSnapshot were still using
JSON.parse(JSON.stringify(...)) which duplicates multi-MB base64 blobs.
Switched to clonePreservingStrings which shares immutable string refs.
Also clarified docstring re: toJSON not being called.

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
in the same flex row as the Split select, preventing overlap at
narrow widths and ensuring vertical alignment.

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
capability badge renders in the model explorer. Add generateVideo to
AUDIO_TARGET_OPTIONS in ConnectionDropMenu so dropping an audio
connection offers Generate Video as a target node.

Add audio-to-video to VIDEO_CAPABILITIES, render audio input handles

Extend handleToSchemaName in getConnectedInputsPure() to map audio-0

The selected-node runner was treating audioInput and videoInput as no-ops,
so select-executing these nodes with upstream connections wouldn't pull

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.
Fixes#106

- 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
display parameters like all other providers.

If a debounced data-edit snapshot was pending when loading or clearing
a workflow, it could fire after undoManager.clear() and push stale
state into the new workflow's undo history. Now both paths cancel the
pending timer and snapshot before clearing.

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.

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.
