functions. Add 13 new tests.

Move generateWithFalQueue, generateWithKie, generateWithWaveSpeed and all
their helpers into providers/fal.ts, providers/kie.ts, providers/wavespeed.ts.

route.ts reduced from 2,838 to 518 lines (POST handler + routing only).
Re-export clearFalInputMappingCache from route.ts for test backward compat.

The loopCount (1x/2x/3x) feature was only applied in executeWorkflow()
but not in regenerateNode(), which is the code path triggered by
clicking the "Stitch" button. This adds the blob duplication logic to
both code paths and includes the UI controls and type definitions.

Validate uploadUrl and fileUrl from fal CDN initiate response through
validateMediaUrl() and HTTPS check before performing the PUT request.
Throws if either URL is missing or fails validation.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Validate fal-provided status_url and response_url against validateMediaUrl()
and domain allowlist (queue.fal.run) before using them for polling. Falls back
to constructed URLs on validation failure.
Also updates mockFalCdnUpload test helper to match the two-step CDN upload
flow (initiate + PUT) introduced in 3fea13e.

WaveSpeed's CloudFront CDN returns `binary/octet-stream` which wasn't
caught by the old `!== "application/octet-stream"` check, producing
unplayable data URLs. Now only accepts content types starting with
`video/` or `image/`, falling back to `video/mp4` or `image/png`.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The old single-POST endpoint (fal.ai/api/storage/upload) returns 404.
Switched to the current fal.ai upload API: initiate via
rest.alpha.fal.ai/storage/upload/initiate, then PUT binary data to
the returned signed URL.

- Delete unused generateWithFal function (replaced by generateWithFalQueue)
- Add 20MB size guard in uploadImageToFal to prevent memory spikes
- Add refresh button to ModelSearchDialog that clears model and schema
localStorage caches plus in-memory fetch cache
- Wire "Try Again" error button to also clear stale caches

Replace blocking fal.run endpoint with async queue.fal.run + 1s polling
to match Replicate/WaveSpeed behavior. Upload base64 images to fal CDN
before queue submission to avoid large inline payloads. Cache schema
mappings in-memory (30min TTL) to eliminate redundant API calls per
generation. Also fix localStorage cache leaking between tests.

Derive provider capabilities from mediaType instead of hardcoding
text-to-image, so isVideoModel is correct for video generations.
Treat application/octet-stream as unhelpful content-type and fall back
to video/mp4 or image/png based on model type. Add safety net in
save-generation to override .bin extension when media type is known.

Adds 48-hour client-side caching to persist model data across dev server
restarts and page refreshes, eliminating repeated API calls during hot
reloading in development mode.

Add Veo 3 and Veo 3 Fast models (text-to-video + image-to-video) with
custom API integration using Kie's /api/v1/veo/ endpoints and numeric
successFlag polling. Also document Kie model integration SOP in CLAUDE.md.

non-HTTP protocols before server-side fetches (with tests)
- URL-encode Kie taskId in poll URL to prevent injection
- Validate WaveSpeed modelId against path traversal in both route.ts

- AudioInputNode: use named event handlers with removeEventListener in cleanup
- deduplicatedFetch: track setTimeout IDs and clear them in clearFetchCache()
- waitForPendingImageSyncs: clear timeout in finally block after Promise.race
- decodeWithMediaBunny: wrap in try/finally to close sink, input, blobSource

Update stale test mocks from currentNodeId to currentNodeIds in
AudioInputNode, EaseCurveNode, and VideoStitchNode tests. Replace
hard 401 return for missing FAL API key with console.warn, allowing
requests to proceed without auth (rate-limited) since
generateWithFal() already handles null keys gracefully.

The presets overlay was being clipped by BaseNode's overflow-hidden container.
Render it through createPortal to document.body with position tracking via
requestAnimationFrame, matching the existing pattern used for comment tooltips.

- Add nano-banana-pro model to Kie provider with schema and image input key
- Reorder Kie generation to process dynamicInputs before fallback image
uploads, preventing double-uploads when schema-mapped connections exist
- Update test mocks for deduplicatedFetch, useProviderApiKeys, and static
handle changes across GenerateImageNode, GenerateVideoNode,
ModelParameters, and ModelSearchDialog tests
- Add test commands to CLAUDE.md
- Fix SplitGridSettingsModal grid preview count (5 → 6 options)

handleNodeDragStop used a hardcoded 300x280 fallback for node dimensions,
causing miscalculated centers for non-standard nodes (easeCurve 340x480,
videoStitch 400x280, audioInput 300x200). Now uses the same 3-level
fallback (measured → style → defaultNodeDimensions) as createGroup.

Remove 36 unsupported Kie.ai models (14 image, 22 video) and add 2 new
ones (kling-2.6/motion-control, topaz/video-upscale), bringing the total
to 22 models. Fix parameter schemas to match official Kie.ai docs:
seedream quality param, flux-2 input_urls, grok-imagine video mode/duration,
kling sound param, wan resolution param, and singular vs array image keys.
Remove dead Veo/Kontext/Runway helper functions and endpoint branching —
all remaining models use the standard createTask endpoint.

Add ~38 new image/video models (Imagen 4, FLUX.2, Flux Kontext,
Grok Imagine, Ideogram, Qwen, Runway, Hailuo, Seedance variants,
Kling older, Wan older) with schemas and endpoint routing for
dedicated APIs (Flux Kontext, Runway). Add pageUrl to all Kie
models and update ModelSearchDialog to use it.

audio visualization, video stitching, and speed curve application.

- Added validation to ensure fal.ai API key is provided in requests, returning a 401 status with an appropriate error message if not configured.
- Updated related tests to reflect the new API key requirement and adjusted assertions for expected responses.
- Modified documentation to clarify that fal.ai API key is now mandatory for model access.
Merge feature/wavespeed branch, adding WaveSpeed as a new provider alongside
Kie. Fix shared integration bugs in both providers: standardize API key headers
to X-Kie-Key/X-WaveSpeed-Key, add both to handleSaveProviders, ModelParameters
headers, CostDialog filter, and ModelSearchDialog badges. Replace per-provider
icon buttons in FloatingActionBar with a single "Browse models" button.

HTML5 drag-and-drop doesn't work inside React Flow nodes because
