+
+With `use-responses-api = true`, responder chat calls go to
+`/v1/responses` instead of chat/completions: same model selection
+(default / vision / factual / retry), the same strict envelope schema
+(as `text.format`), tools in the flat Responses shape, and
+`reasoning` = config `reasoning-effort` — tools + reasoning are
+allowed here (the chat/completions 400 from ENV-21 does not apply).
+Flag off (default) = the ENV-21 path, byte-identical behavior.
+Classifier, consolidation and task-proposal calls stay on
+chat/completions.
+
+### ENV-23 — Responses tool loop is stateless and keeps reasoning (coverage: test)
+
+The Responses path runs with `store=false` and
+`include=["reasoning.encrypted_content"]` (nothing retained
+server-side). On a function call, the reasoning and function_call
+output items are passed back as input — reduced to their input-shape
+fields, since response-only fields like `status` are rejected as
+unknown parameters (live 400, 2026-07-17) — together with one
+`function_call_output` per call (matched by `call_id`, result
+sanitized per SAF-03), so the model continues one chain of thought
+across tool rounds. Up to `responses-tool-rounds` (default 4) rounds
+may call tools; an exhausted loop forces a final tool-less answer.
+
+### ENV-24 — Responses refusals are failed attempts (coverage: test)
+
+A refusal content part in the Responses output yields no answer
