Answered byCLAIM-157 — Relative to a stated target, a combined form is one system while its joint dynamics are nearly decomposable with the form as a block whose gap beats the Occam factor, and it lasts as long as that block persists; the unit is the gap-isolated block, not any member
BearingTHEORY-579 — If belief is individuated by functional role, an external store that is constantly consulted, directly available and automatically endorsed can carry a standing belief, so the material vehicles of some mental states extend beyond the skin; the step from coupling to parthood rests on that premise and a parity principle the authors state rather than argue, THEORY-448 — On a substance ontology, a gestated foster that is part of the pregnant organism either is no substance, so that mammals begin at birth and the foster is not the later baby, or is part and substance at once, which leaves no consistent count; a process ontology keeps both parthood and foster–neonate identity, at the price of a count between one and two that it does not define, THEORY-443 — Being a biological individual is not being an organism: evolutionary (Darwinian) individuality and physiological individuality come apart, and each is found among parts of organisms and groups of organisms as well as among organisms, so a part or a group can be an individual of one kind and not the other

Why it is a question

It has come up three times in one day:

The record has candidate tests, each measuring something different:

  • Mutual entrainment (CLAIM-172), which measures timing.
  • Reciprocal compensation (LIT-902, unread), which measures whether a goal is preserved.
  • Near-decomposability priced by an Occam factor (CLAIM-154, LIT-905), which measures strength.
  • Conserved coherence (CLAIM-161), which measures persistence.
  • Gluing (CLAIM-153), which measures unity across contexts.

QUESTION-009 asks when coordination makes an additional agent. This asks the prior question: when it makes one system. Selfhood stays a further question again, kept apart by ADR-024.

Readings of 2026-10-14 bear on all three parts, and none answers it:

  • How long. THEORY-268 (LIT-953, NOTE-756): an emergence measure averaged over transitions can be positive while it is negative at particular ones. A criterion of unity computed as an average gives no verdict about a moment, so “how long” needs a window and a rule for how many failing moments end the form.
  • One system, and where. THEORY-254 (LIT-955, NOTE-814): tangles make “cannot be pulled apart” two-sided and relative to an order k, and they match communities only where structure is strongly delineated. Each region has its own best order, so one global threshold splits some forms and misses others.
  • Boundary found by timing. THEORY-265 (LIT-989, NOTE-773): phase synchrony within strongly coupled modules makes each respond as a unit, and global synchrony does not. “Who is synchronised with whom” defines the collective, but the boundary is built in by the couplings, so the timing finds it rather than drawing it.

What would count as an answer

A criterion that, given a stated target and measurements of a candidate, returns a verdict that can be wrong. It should say which variables are inside, from when to when, and with what margin. It must also handle the cases the record already holds: the couple after the song must come out two. One-way drive, such as the metronome or the nerve and the muscle, may come out one system with a hierarchical architecture. Version 1 required the opposite, and that requirement was withdrawn (CLAIM-167). A criterion that every pair of interacting things satisfies is not an answer (CLAIM-010’s permissiveness, in another form).

The proposed answer is CLAIM-157. Its first objection, that one-way drive should not pass (CLAIM-173), was rejected by CLAIM-167.
