## Export decoder fix — 10 October 2026

The shared exporter uses sequential frame reading with lookahead for variable-frame-rate and late-start recordings. The former 1.067s failure was reproduced in Chromium, then the fixed worker produced WebM exports with audio, including trims, speed changes, gaps and repeated footage. Decoded file timing and pixels were checked. Extension build 0.1.3 includes the fix. Installed-extension and MP4 verification remain pending. See EXPORT-FIX.md for deployment instructions and full test scope.

# Feature status — Glidelo 0.1.0

This is a development implementation, not full product completion. A tested shared function does not mean its entire platform journey was tested. Original full requirements remain in docs/BUILD_BRIEF.md.
