notes

--enable-log-requests is log-LEVEL dependent: at INFO it logs request id, params and LoRA request; prompt text and token ids require DEBUG. --max-log-len truncates. This is the concrete finding for the compliance slice: prompt bodies land in the application log stream at DEBUG, and --max-log-len is the only truncation control - there is no redaction or PII filter in the engine.
