On-device coach for free-form training questions in the PowerliftME app —
effort (RPE/RIR), recovery and readiness, technique cues, basic training
nutrition, and on-topic refusals.
Program-specific facts (today's prescribed load, peak timing, weeks to meet,
on-track status, …) are answered by a deterministic rules engine inside the
app, never by this model. The LLM handles the open-ended advice around it and
replies in the athlete's own language.
