update_post

Update an editable post (draft/scheduled/error/active). Only the content and schedule fields you supply are changed — omitted fields keep their stored values (name, postType, platforms, captions, media, scheduledFor, etc.). Pass draft=true to save without publishing (skips required-field checks); omit draft or pass draft=false to reconcile and publish. Reconciles platform submissions. A requested platform with no active connection never fails this call either (same as create_post) and the response is `{ status: "no_connection", missingPlatforms, scope, post: { id, status } }` instead of the usual `{ id, status }`. PLATFORM RULES (enforced — violations rejected): Post types: `announcement` works on every platform; `event` and `offer` are Google-only (any social platform ⇒ must be announcement). Caption char limits: google 1500, facebook 30000, instagram 2200, x 280 WEIGHTED characters rather than typed ones — Japanese/Chinese/Korean characters and emoji cost 2 each and any link costs a flat 23, so a non-Latin caption fits roughly 140 typed characters; setting linkUrl appends that link to the caption for a further 25 weighted (X thread mode is exempt from the limit entirely), linkedin 2000, pinterest 500, mastodon 500, bluesky 300, youtube 5000. Media (per platform, using each item's `platform`): facebook ≤10 images OR ≤1 video, no mix (carousel = 2–10 images only, per-card headline ≤80 / description ≤200); instagram requires ≥1 media, ≤10 images OR ≤1 video, no image/video mix; x ≤4 images OR ≤1 video, no mix; linkedin ≤5 images OR ≤1 video, no mix; pinterest image-only, exactly 1, required; mastodon ≤4 images OR ≤1 video, no mix; youtube video-only, exactly 1, required. Google event ⇒ eventTitle (≤58 chars) + eventStartAt + eventEndAt (end after start) required. Google offer ⇒ ctaType + ctaUrl required. scheduledFor must be in the future. Drafts (draft=true) skip required-field checks but still enforce all structural checks above.
