nx_ims_monitor_gate.nx

nx_ims_monitor_gate.nx -- REFEREE for the IMS A1 orphan + link-rot monitor. Proves the PURE logic with in-memory fixtures (no I/O) AND with TEETH -- a monitor that always says "0 orphans / 0 dead" would pass a clean fixture, so every clean assertion is paired with a PLANTED-fault assertion that FORCES a specific non-zero finding at a known identity: T1 CLEAN corpus (every non-root page linked, no dead links) -> orphans == 0 AND dead == 0 T2 PLANTED ORPHAN (page "lonely" that NOBODY links) -> orphans == 1 AND the orphan is exactly rowid(lonely) [TEETH] T3 PLANTED DEAD LINK (a page hrefs "/wiki/ghost.html", no such page) -> dead == 1 AND the dead target is exactly "ghost" [TEETH] T4 NEG-CONTROL: the root (start) is linked by NOBODY but is NOT flagged -> start NOT in orphans, while a real orphan IS (proves the root exclusion is real, not "flag nothing") [TEETH] T5 NEG-CONTROL: the monitor does NOT touch the corpus -- a self-link does not rescue an orphan, and a present target is NOT a dead link. GREEN iff T1..T5 with EXACT counts + identities. exit 0 GREEN / 1 RED. Logs to knowledge/status/ims_monitor_gate.log.
