HyperFrames v0.8.17

Released on 2026-08-28.

Studio now exposes live editing state to agentic browsers, including browsers without native WebMCP. Renders now fail instead of silently succeeding when sub-compositions, media extraction, or artifact validation break, while nested runtime videos keep distinct identities.

Features

  • Studio: Fall back to a WebMCP polyfill where the browser has none (097d901d7, #3514).
  • Studio: Expose Studio's live state to an agentic browser (WebMCP) (94da403d6, #3511).

Fixes

  • Producer: Enforce video extraction failures by default (#3372) (4d87f8bba, #3526).
  • Core,producer: Stamp render ids on empty-src media and pair the snapshot by them (9eb84c91b, #3513).
  • Engine: Fail render on sub-composition script failures (#3352) (e69be30e9, #3528).
  • Producer: Assert render artifact duration and frame count before commit (05275c1e8, #3506).
  • Core: Read CSS animation opacity through color grading's own hide (#3329) (e5c7dc75e, #3507).
  • Studio: Let a failed DOM edit report that it failed (21bcd5745, #3510).
