buildRetryFeedbackEntry was L1/SYSTEM, so PromptRenderer folded it into the
leading system block — far from the assistant/tool transcript and weaker than
the original stage task. Flip it to USER role and give the renderer an explicit
trailing repair-mandate slot (a sourceType set, extensible for recovery later):
repair mandates are lifted out of the inline flow and emitted once as the final
message, after the tool evidence and the steering anchor. retryFeedback is
already in REQUIRED_SOURCE_TYPES so it stays unprunable. Golden renderer test
proves the final message is the repair USER mandate and leading system no longer
carries it.
