The forms a goal-directed conversation takes
ATLAS is a structural readout of goal-directed conversations. It does not read text; it reads motion form.
Each bar is an observed conversation shape. Each node in the tree is a shape the grammar allows: a filled node is a shape we have seen, a dashed node is one the grammar allows but we have not seen yet. A paired block is two agents in one exchange; ? means their coupling limit is not measured yet.
386 measured conversations (clean half-chiasm) → 228 exact shapes
C converging S holding M drifting · length = turns · thickness = conversations sharing the shape.
Across these shapes, motion returns to holding 400 times — a move back into S from C or M, where a conversation re-stabilises after converging or drifting.
The grammar, as a tree
Two negations generate every shape: no shape starts with M, no M→C inside. What survives is counted by Fibonacci. A node is a valid shape — filled if we have seen it, dashed if the grammar allows it but we have not seen it yet. The colour of a branch is the move it just made: one of the five allowed transitions.
CS C→SCM C→MSC S→CSM S→MMS M→S
The shapes run out while the grammar keeps allowing more
At each length: the grey bar is how many distinct shapes actually appear; the small number above it is how many the grammar allows. They diverge — the real shapes saturate and die out, the allowed set keeps exploding.
seen (bar, lower number) saturates at 6 for length 4–7, falls from length 8, hits 0 at length 12. allowed (upper number) keeps growing 2, 4, 6, 10, 16, 26, 42… The base shapes are few; long chromosomes are rare tails.
Chiasm loci · paired rails
Two agents in one exchange, drawn as two rails by turn count (they dialogue, so their lengths match). The lock is 1 when the two shapes fuse, Ø when the border is impossible, ? when it cannot yet be decided. S is never auto-declared: it needs the coupling limit, which the product does not measure per turn.
