Audits every ContextEntry producer against PromptRenderer's three real
render destinations (system fold / inline / trailing user slot). Finds
four escalation-grade entries roled SYSTEM and therefore buried in the
leading system message: recoveryTicket, remainingDelta, groundingFeedback,
rejectionFeedback. remainingDelta additionally mutates the cached system
prefix every turn.
Report only, no code changes. Re-role work filed as #313.
