Crawler/snapshot status: which native templates are captured (reel / photo / profile-switch), whether you're ready to post, and exactly what to do if a (re)snapshot is needed. The crawler captures passively when you post by hand on facebook.com — re-snapshot only when Facebook rotates its payload and replay starts failing.

Read which Facebook page/profile the browser tab currently posts AS (read-only, no switch). Useful to confirm identity before posting.

Bridge + extension health: is the bridge up, is the Chrome extension connected, are the reel/photo templates captured, and tab freshness/TTL.

Publish a Facebook photo (1 image) or album (N images) from local files via the browser extension (native web API, NOT the Graph API). Requires the bridge running, a logged-in facebook.com tab, and a captured photo template (see capture_status).

Publish a Facebook Reel from a local .mp4 via the browser extension (native web API, NOT the Graph API — avoids reach suppression). Requires the bridge running, a logged-in facebook.com tab, and a captured reel template (see capture_status).

Switch the browser session to a target Facebook page/profile id so subsequent post_reel / post_photos go out AS that page (one account, many Pages). Requires a captured CometProfileSwitchMutation template.
