/content/npcs
Per-NPC knowledge lists — an explicit list of what each NPC knows (charter §6). This is the entire content the NPC has to draw on, injected as knowledge: [...]. Not a prompt suggestion — the whole design.
POC scope (§17): two NPCs with authored knowledge lists.
Companions (Cadwyn, Brannoc) are voiced too but carry more (approval, humiliation log) — see charter §9.
