AI Summary

This SDK release improves video export tracking by using duration and frame rate for progress estimation instead of capped metadata. It introduces `--video-timeout-ms` as an inactivity timeout and adds CLI reporting for throttled phases, AI reuse, and a new `--video-bitrate-mbps` flag.

Key Highlights

  • Video progress now estimates complete export from duration and sampled frame rate.
  • `--video-timeout-ms` is now an inactivity timeout for active long-running exports.
  • CLI reports throttled phase, percentage, frame count, and AI reuse progress.
  • Adds `--video-bitrate-mbps` parameter to the CLI.
  • Publishes progress callback contract in TypeScript declarations.

New Features

  • Improved video progress estimation algorithm
  • New CLI flag for video bitrate configuration
  • Enhanced TypeScript API for progress callbacks

Full Release Notes

## Package / SDK release

### Highlights

- Video progress now estimates the complete export from duration and sampled frame rate instead of treating the capped metadata probe as the total.
- `--video-timeout-ms` is now an inactivity timeout: active long-running exports can exceed it, while genuine stalls still fail with progress context.
- The CLI reports throttled phase, percentage, frame count, and AI reuse progress; adds `--video-bitrate-mbps`; and publishes the progress callback contract in TypeScript declarations.

### Verification

- Production build passed.
- SDK smoke suite: 8 passed, 0 failed.
- Complete serial suite: 1,698 total; 1,666 passed; 32 skipped; 0 failed.
- Pull-request CI and post-merge `main` CI passed.
- A real 240-frame video completed in 61.9 seconds with a 60-second inactivity timeout because frames continued advancing; a 100 ms no-progress interval failed as expected.
- Tarball SHA-256: `4e15ae8802047cc60ac8ccfa03b6cac6d683f44b23174f0f0d3a79fc65384237`.

Based on the original implementation and tests contributed by @shantz1 in #110, completed through #135 and #137.

This is a package/SDK-only release. It does not contain a new userscript or Chrome extension artifact. The website is a separate deployment surface.
