Add hoveredNodeId to store, set from BaseNode mouse events, read in
FloatingNodeHeader. Controls now appear when hovering any part of
the node, not just the floating header strip.

After disconnecting an image edge, the target node's inputImages data
was not cleared. On regeneration, useStoredFallback would pick up the
stale images and send them to the API, causing results to still resemble
the old reference. Now removeEdge and onEdgesChange call
clearStaleInputImages to reset inputImages when no image-source edges
remain on the target node.

The else-if chain in blockedTypes detection meant that when a switch/
conditionalSwitch node was itself dimmed but had an enabled output,
the finalDimmed.has(source) check was skipped entirely. Changed the
dimmed-source check from else-if to a standalone if so it runs for
all source types, including switch and conditionalSwitch.

The dimming algorithm processed potentially-dimmed nodes in arbitrary
order, causing nodes downstream of a rescued convergence point to stay
dimmed. Fix by topologically sorting the candidate set (upstream-first)
and checking finalDimmed instead of potentiallyDimmed, so rescued nodes
properly propagate their active status downstream.

Adds an evaluationPaused flag that lets users reset evaluation state
and un-dim all downstream paths. The flag auto-resets on workflow
execution or manual rule edits.

The customTitle and comment fields are typed as string | undefined in
ConditionalSwitchNodeData. The null values were masked by an 'as' cast
but caused strict type errors. These fields are optional and don't need
explicit defaults.

The same 20-line block for evaluating rules and updating node data before

ConditionalSwitch should act as a gate/trigger, not a data router.
Active outputs now trigger downstream execution without forwarding
the upstream text through the connection.

Nano Banana 2 (gemini-3.1-flash-image) supports a new searchTypes API

- Add executeConditionalSwitch passthrough executor
- Add conditionalSwitch to VALID_NODE_TYPES in validation
- Export ConditionalSwitchNode from components index (component created in next task)
When paths reconverge downstream of a Switch, dimmed nodes (from disabled
outputs) still held stale data from previous runs. getConnectedInputs now
accepts dimmedNodeIds and skips any source node in the dimmed set, preventing
disabled Switch paths from leaking data into downstream nodes.

A Prompt (text) connecting to a Generate node shouldn't prevent dimming
when the image input from a disabled Switch is blocked. The cascade now
only un-dims a node if an active input provides the same data type as
the blocked path (e.g., another image source replaces a disabled image).

- Capture prevUnsaved from hasUnsavedChanges before set() call
- Add hasUnsavedChanges to rollback set() call on save failure
- All three fields now properly restored: workflowId, workflowName, hasUnsavedChanges
- Prevents dirty flag from remaining stuck at true after failed save
- Remove directoryPath field from WorkflowFile literal in saveToFile
- Change loadWorkflow fallback chain to exclude workflow.directoryPath

- Add tests for wrapping behavior and empty array handling
Zundo-based undo/redo was causing image flickering, failing to restore
deleted nodes, and creating memory issues from large state snapshots.
Removes the entire workflow undo/redo system while keeping the
independent annotation canvas undo/redo intact.

Replace BINARY_DATA_KEYS (strips all binary) with BINARY_TO_REF mapping
that only strips binary data when a corresponding ref exists (recoverable
from disk). Fields without refs (imageA, imageB, capturedImage, etc.) are
kept in snapshots since they're unrecoverable. After undo/redo, hydrate
missing binary data from refs using existing hydrateWorkflowImages().

When importing a workflow via file picker, loadWorkflow had no way to
find the image files on disk because directoryPath was only stored in
localStorage (which doesn't survive browser switches or clears).
Now auto-save embeds directoryPath in the workflow JSON, and
loadWorkflow uses it as a fallback after the workflowPath parameter
and localStorage config.

Saved workflows can contain multiple edges with the same ID (from
repeated connections or migration normalization). React warns about
duplicate keys and may render edges incorrectly. Deduplicate by
keeping the last occurrence of each edge ID on load.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Saved workflows could contain edges targeting nanoBanana nodes with
indexed handle IDs (image-0, text-0) from a previous schema-based
handle format. GenerateImageNode now always renders non-indexed
handles (image, text), causing React Flow error #008 on every
interaction. Normalize these edge handles during loadWorkflow.
