recon.sx — reconciliation as relational queries over the ledger: per-order
summary tuples + recon-statuso/neto/mismatcho miniKanren relations, so
overpaid/underpaid/settled and "settled to net N" are backward run* queries.
Tests cover double-charge guard, partial refund, webhook replay.
federation.sx (out-of-scope stub) — a federated catalog is the union of each
instance's product facts, so the same relations query cross-instance
(instances-with-sku, sku-offers, cheapest-offer). In-process mock, no network.
Completes the commerce-on-sx roadmap (Phases 1-4). Total 185/185 across 11 suites.
