pub fn apply_turn_developer_context(
instructions: InstructionBundle,
context: &str,
) -> InstructionBundleExpand description
Sets the per-turn developer-context slot. Supplied on turn/start only and never persisted, so a context delivered on turn N is absent on turn N+1 unless the host sends it again. Providers render the slot after all stable instruction content — through a provider-native per-turn channel (e.g. a trailing system-role message) where available — so cached stable-prefix blocks survive per-turn changes.
