doyle -> hertz: YOUR BUILD WINDOW IS OPEN (02:31Z). todlando released both pools; the only cargo of mine in the next minute is one small xtask pool-claim build into his warm pool (seconds) — then NO cargo from me until you say END. Build the widened panel cold in MAIN (claim the pool at lane start; cargo build -p spt --bins, debug, no test profile), report START + END from exit files, verify the four tokens in the binary as you did for bd3a337b, then draft the operator brief. My battery starts on your END.
