Claim tree

Assigns each surviving claim a slug and a UUID, attaches the edges edge-inference produced, and writes one markdown file per claim into claims// with the paper's index.md beside them. It calls no model and needs no credentials — the reasoning already happened upstream — but it does need those edges. Run it without them and the claims are written with no structure, and it says so.

It refuses to overwrite a non-empty paper directory. The claim files are edited afterwards by hand and by later layers, and a silent overwrite would discard work no ledger records. A run of this layer is by definition a new version, so the command passes --replace: it moves the current tree to runs//claim-tree.v/ — keeping every version's bytes addressable — then writes the new one and carries forward the alt- claims, rules-out edges and reproduction records the induction chain does not itself produce.
