+- combat: active combat materially organizes the scene, including
+  initiative-like exchanges or sustained hostile action. Planning a fight or
+  discussing a completed fight is not combat by itself.
+- narrative: current-session in-world play that is not principally active
+  combat, a prior-session recap, or sustained out-of-character session
+  discussion. This includes exploration, travel, dialogue, investigation,
+  in-character planning, and aftermath.
+- recap: the scene's organizing purpose is to recount events from a previous
+  session for the table. An in-world character recounting history during
+  current play remains narrative.
+- meta: the scene's organizing purpose is sustained out-of-character
+  discussion about the game or session rather than advancing current in-world
+  play.
+
+Narrative is the default for actual current-session gameplay that does not meet
+another definition. When the accepted chunk is mixed:
+
+1. use combat when active combat is a substantive central activity, even with
+   brief setup, rules clarification, or immediate aftermath;
+2. otherwise use recap when recounting a previous session is the chunk's
+   primary table purpose;
+3. otherwise use meta when sustained out-of-character session discussion is
+   primary and in-world progression is no more than incidental; and
+4. use narrative for all remaining current-session in-world play.
+
+Brief table talk, dice resolution, rules clarification, jokes, or
+administrative comments do not make a gameplay scene meta. A short recollection
+used to orient current action does not make a scene recap.
+
+The title must be a short, distinguishing phrase rather than a sentence,
+chapter number, or generic label such as "Scene." It may use names and places
+established by the transcript or disambiguated by campaign references, but it
+must not invent a proper noun.
+
+The summary must briefly state the main activity and material transition or
+outcome established within the accepted chunk. Do not add analysis, inferred
+motives, hidden state, future consequences, relationship claims, or facts from
+outside the chunk. Campaign references may disambiguate names but never add
+events or lore.
 
 Do not return identifiers, source identifiers, source ranges, unit identifiers,
 participants, confidence, or any fields besides kind, title, and summary.
