+`extract/dnd/scene-descriptions/combat_semantics` is not in a production default chain. To opt in, replace the scene extractor validator chain with the current ordered chain plus the semantic validator last, and set a positive producer retry budget if a rejection should request a corrected scene:
+
+~~~yaml
+extract:
+  module: dnd/scene-descriptions
+  retries: 1
+  validators:
+    - generic/valid_json
+    - extract/dnd/scene-descriptions/shape

+    - generic/valid_json_schema
+    - extract/dnd/scene-descriptions/source_relatedness
+    - extract/dnd/scene-descriptions/combat_semantics
+~~~
+
+An override replaces, rather than extends, the default chain. See [Module Bindings And Validators](#module-bindings-and-validators) for binding, profile, repair, retry, and failure-policy rules.

 [Configuration](../config.md#production-validator-keys-and-default-chains).
 
+The optional `extract/dnd/scene-descriptions/combat_semantics` validator is the
+D&D family's LLM-backed review of only combat versus non-combat classification.
+It selects the shared combat-policy prompt fragment, receives the proposed kind
+and current chunk, and maps its verdict deterministically into producer
+guidance. It does not assess titles, summaries, non-combat subtype, or scene
+boundaries; deferred boundary-coherence review remains separate. It is opt-in;
+[Configuration](../config.md) owns selection and retry/failure behavior.
+
+Before proposing default-chain inclusion, run a deliberate provider evaluation
+against the synthetic corpus and record false acceptance, false rejection,
+producer-correction success, added calls, latency, and token use. Default tests
+remain offline and do not measure provider quality.
+
 Every D&D rejection describes the correction in transcript-grounded domain
 terms, using contextual names, artifact fields, and source segment ranges when
 useful. The guidance must not ask the model to reproduce durable entity IDs,
