JSON-over-stdio loop on tokio with four ops:
- ping liveness
- resolve Tier 1 rustypipe → Tier 2 yt-dlp -j fallback. Typed
errors (age/region/private/not-found) short-circuit
Tier 2 so we don't double-hit a wall. Pass-through
serialization of player.details + selected streams,
so the Python addon parses what it needs without us
coupling to rustypipe's struct shape.
- rip Tier 3 yt-dlp downloads bestvideo+bestaudio to a
caller-supplied dest_dir, returns the resulting
path + size for the addon to play as a local file.
- sponsorblock SHA-256 prefix lookup (first 4 hex), filter to the
exact video_id locally. Categories default to
[sponsor, selfpromo, interaction]; caller can override.
Smoke ran in crafting-table against dQw4w9WgXcQ — rustypipe 0.11.4
still resolves cleanly in 2026-05, sig decoding intact, both 4K AV1
video and Opus 128kbps audio came back with valid signed URLs.
SponsorBlock returns empty segments for music videos (as expected).
