If renewal fails +or ownership becomes uncertain, stop all edits before committing and hand the +attempt back with its changed paths identified. Release the claim on success, +failure, or handoff; an expired lease may be acquired normally, but never delete +or rewrite claim refs by hand. `autoform claim list` is the inspection surface. +Claims are temporary operational state, never article frontmatter, and they do +not replace normal branch conflict checks. + +Each parallel agent uses its own Git worktree.

It does not prove a weaker +statement, add an unused hypothesis, or alter the public statement merely to +make tactics succeed. Inspect the declaration's axioms when the result or its +proof chain could conceal an assumption. If the exact theorem cannot be proved, +report the remaining goal and the smallest missing lemma; never mark it done. + +Use counterexample and proof-strategy agents after a failed route rather than +blindly retrying.

Re-read the derived state after each +wave, choose newly unblocked leaves, and stop when no dispatchable work remains +or every remaining node has an explicit mathematical or ownership blocker. +Report changed nodes, claims released, Lean checks, independent review results, +and blockers without claiming more coverage than was verified. + +For a concrete dependency-based handoff, read the concise +[Cabannes thesis walkthrough](references/thesis-worked-node.md).
