Summary

• Serializer and canvas card now pass the block's canonical mode overrides (__canonicalModes) to sub-block conditions, like the editor and autolayout already did
• Fixes Video Generator settings being dropped when a start frame sits in the inactive reference input: conditions guessed the active member from which one held a value, hid prompt-only settings (fal aspect ratio, Runway ratio), and the request fell back to the model default
• New shared withCanonicalModes helper in lib/workflows/subblocks/visibility.ts replaces the inline copies in the editor layout hook, autolayout and dropdown options
• Only the Video Generator reads __canonicalModes, and the key never reaches serialized params

Type of Change

• Bug fix

Testing

• New field-analysis.test.ts cases (frame left in the inactive upload / inactive reference input) and a new canvas-card-fields.test.ts case; all three fail on the pre-fix code and pass now
• Ran serializer, subblock, workflow blocks, autolayout, editor and video_generator suites (46 files, 379 tests), bun run lint, check-block-registry.ts origin/staging

[Medium impact] The PR appears safe to merge; no actionable issues were found.

Summary

Passes the block’s saved basic/advanced choices to video field conditions so an inactive start frame no longer hides settings.

• The Video Generator uses the selected start-frame input for its settings.
