+ * Voice result envelope: what a tool result should SAY and what it should
+ * SHOW, composed by code rather than by prompt prose.
+ *
+ *   { say, display, referents?, schedule? }
+ *
+ * - `say` is one short spoken line (≤25 words, numbers verbatim). Material
+ *   caveats are folded in as one or two words ("stale", "feed unavailable").
+ *   `null` means the model continues naturally with nothing extra to say.
+ * - `display` is for the voice card and is never read aloud unless the user
+ *   asks why, how sure, or which source.
+ * - `referents` number the things the card lists, so "the second one" can
+ *   resolve later.
+ * - `schedule` is `speak` (default) or `silent` (a lookup the model uses to
+ *   continue, not something to read back).
+ *
+ * Builders are small pure functions keyed by tool name. Tools without one are
+ * returned unchanged.
