+### Q-057: Composable behavior generation — decompose culture × role × context into assembled behaviors
+
+- **Status:** Open
+- **Raised:** Sprint 25, ticket #630 review discussion
+- **Priority:** High (blocks scaling beyond hand-authored content)
+- **Context:** Current behavior pools are hand-authored per culture×zone×role combination (`typical_behaviors` arrays in zone spec RON files). At ~50 behaviors per role × 4 roles × N zone types × M cultures, this is O(roles × zones × cultures) custom content. Each cell is effectively a unique location — "rural zone spec" is really "Krenn rural settlement content" with the name filed off. This doesn't scale to multiple cultures or zone types.
+- **Question:** Should the generator compose observable behaviors from smaller primitives instead of drawing from pre-written complete sentences? Proposed decomposition: (1) **role action templates** — generic observable stage directions per role, culture-neutral, (2) **culture modifier sets** — culture-specific flavoring (Krenn mannerisms, speech patterns, social norms) that overlay role actions, (3) **context tags** — on-shift, off-duty, break-room, social-site-type that filter/weight which behaviors are available. The generator assembles these at runtime.
+- **Implications:** Changes the content authoring model from "write 50 sentences per role per zone per culture" to "write role actions once, write culture modifiers once, compose at runtime." Server needs a composition engine (#633); copy needs to author the decomposed format (#634). Part of the Sprint 25 PoC spike.
+- **Cross-reference:** #630 (behavior pool expansion), #633 (server: composition engine), #634 (copy: decomposed content format), D-121 (voice is culture-driven), D-122 (all NPCs generated)
+- **Assigned to:** Tyre, Mellanie, Miri
