Alpha Compose Proto changelog

Released changes for the independent Alpha Compose Proto playback harness.

0.8.0 - 2026-07-30

Added

• Authenticated fixed-folder source discovery and private owner-bound playback.
• Recording-clock inspection, range-aware media streaming, and bounded browser diagnostics.
• On-demand private H.264 browser previews with durable preparation, cancellation, retry, reconciliation, and cache reuse.

Changed

• Browser previews now adapt supported source streams while preserving requested playback ranges.
• Proto infrastructure, deployment, identity, and spend controls remain isolated from the main Alpha Compose release.

Fixed

• Recovered media loads clear stale failure diagnostics.
• Timecode and auxiliary-stream handling no longer prevents otherwise valid browser previews.
