• A model selection can occur while this promise is pending. The completing transition then unconditionally deletes pendingBySession, so the recursive request loses the newer transition and reaches recoverCurrentModel, which creates its checkpoint with basePayload set to undefined. Request-specific fields such as reasoning effort or text verbosity are therefore dropped for the newer model. Preserve/version the pending transition and only delete the transition that actually completed, so the recursive call takes the pending path and forwards this request's basePayload.

		const activeTransition = transitionBySession.get(sessionId);
		if (activeTransition) {
			await activeTransition;
			return prepareRequest(model, ctx, requestInput, basePayload);
