A fair, defensive guardian for a solo builder's usage meter, ported from CONCIERGE's bash token-scheduler to one tested Rust binary (tf). Estimates fan-out cost with a converging estimate→actual EWMA, requires an explicit +Xk budget, throttles waves, and gates each wave against the LIVE rate-limit window (fail-closed) — halting before a paid lockout and resuming cheaply from a per-job ledger that records only what's LEFT. Off-peak runs reserve a morning allowance. Durable, session-safe scheduled jobs (project + per-machine registry) re-arm after a crash and install as OS-cron. A Stop hook writes the session.json .tokens actual-spend signal that makes convergence work. Determinism is proven by cargo frozen-vectors + a byte-for-byte differential against the bash oracle. /schedule routes a job; the token-scheduler skill is the discipline that calls tf.
