bot.py:
- Run all yt-dlp/ffmpeg/ffprobe/file-IO/base64 work off the event loop via
asyncio.to_thread, bounded by a Semaphore(2); the loop no longer freezes
bot-wide during downloads/encodes.
- download_attachments=False; VideoTracker fetches only video attachments lazily
instead of the library base64-ing every attachment of every message.
- last_video keyed per (group, sender) with group-latest fallback so /speed and
/rev stop silently targeting a stranger's video; proactive TTL sweeps free the
big base64 blobs and bound recent_urls growth.
- _reencode guards 0/NaN ffprobe duration and adds -maxrate/-bufsize; /rev now
size-checks + re-encodes + faststart like the other paths.
- Twitter URL regex no longer merges space-separated links (keeps i/web/status);
dedupe repeated URLs within a message; mark-handled only on success/no-media so
a corrective edit can retry; 'unsupported url' surfaced instead of silently dropped.
- All sends wrapped (catch SendMessageError); base64 decode guarded; edit/sync
attachment envelopes handled; /cookies temp file created 0600.
deploy:
- Pin signalbot==1.1.0, yt-dlp floor, add missing yt-dlp-ejs.
- Pin signal-cli-rest-api by digest + add /v1/health healthcheck.
- Restart=always (the library never exits non-zero when wedged).

/clip <seconds> in a link's message overrides the default 60s clip
window (capped at 600s); with a ?t= it sets the window length, without
one it clips from the start. /help lists every command with examples.

When a YouTube link carries a t=/start= offset, download only a 60s
window around it via yt-dlp --download-sections instead of the whole
video. Hour-long uploads shared at a timestamp previously failed the
100 MB Signal limit even after re-encoding.

Group-chat bot that downloads videos from X/Instagram/YouTube/TikTok links
via yt-dlp and posts them back, plus /speed and /rev video toys.
