The engine scores readiness and, on the next get_todays_session, reshapes the workout accordingly (reduce volume / reduce intensity / recovery day). Returns the readiness score + modifier.
regenerate_program
Rebuild the whole program from the stored profile (~20s AI generation). Use after a profile change or a plateau. Rebuild the whole program from the stored profile (~20s AI generation). Use after a profile change or a plateau.
