1// nx_cms_forum.nx -- CMS COMMUNITY FORUMS (sovereign threaded discussions). The bbPress/BuddyPress class, 2// made Nishi-native and DRY: a forum reply is moderated by the EXISTING nx_cms_comments engine (rule 15 -- 3// the forum does NOT re-implement spam scoring or visibility, it COMPOSES the proven module), so the same 4// privacy-native on-box moderation that protects comments protects forum posts. The forum adds only what is 5// genuinely its own: per-thread STATE (open/locked) gating new replies, and a DETERMINISTIC ordering rank 6// where pinned/sticky threads sort above the rest. license_tier: ORIGINAL 7import "nx_cms_comments.nx" 8import "nx_syscalls.nx" 9 10// thread states 11const NX_FORUM_OPEN: i64 = 0 12const NX_FORUM_LOCKED: i64 = 1 13 14const NX_FORUM_REFUSED: i64 = 0 - 1 // a reply rejected because the thread is locked 15 16// ordering bands / recency horizon (the data-driven seam; prod = svc-config, rule 11) 17const NX_FORUM_BAND: i64 = 1000000000 18const NX_FORUM_HORIZON: i64 = 1000000000 19 20// can a new reply be posted to a thread in this state? 21func forum_can_reply(state: i64) -> i64 { if state == NX_FORUM_OPEN { return 1 } return 0 } 22 23// post a reply to a thread: REFUSED (-1) if the thread is locked; otherwise returns the moderation 24// status the reply lands in by COMPOSING nx_cms_comments (clean -> PENDING, link/banned -> SPAM).
