Square keeps an event's created_at across every retry, and the receiver refused anything older than five minutes, so every retry of an event first sent while cloud was down (Recreate, ten rollouts a day) was refused until Square gave up. The verifier now lives in payment/providers/square and needs only the key and the URL; thirdparty/square is the API client and no longer registers itself or verifies anything, so every registry holds one Square type. Replay is stopped by the event id instead: each verified event is recorded once for the whole deployment, keyed on the verifying processor and the event id with an insert-if-absent swap, so a repeat is a duplicate under any path or org. The path names the one processor that verifies, and only one that holds its webhook secret may: an unknown name, or a verifier that needs no secret, is refused rather than tried. The books an event lands in are the verifying account's, else the deployment's brand — never a header or session, which on a replay are the replayer's. An effect that did not land (a store or the ledger did not answer) leaves the delivery open with a 503, so the provider redelivers; it used to be acknowledged and never retried. A settlement reads the payment index before the org's books, because an in-session charge's receipt is in the payer's org. POST /v1/commerce/webhooks/:provider is declared once, in setupRoutes, so standalone and embedded commerce serve the same address; the /v1/billing/webhooks spelling is gone. thirdparty/kms read /v1/kms/orgs/<org>/secrets/..., which cloud no longer serves, and was off in production anyway, so per-org payment credentials never loaded. It is deleted. secrets.Org reads orgs/<org>/<name> through the host's reader, the caller re-pointed at that org with zip.ActingAs so the KMS tenancy check admits it, and payment.Hydrate loads an org's credentials where the org receives the money: storefront checkout, storefront subscriptions and wire, and the brand's bank for the billing wire rail. Hanzo's own billing no longer reads the paying org's credentials; it charges the deployment's account, as it did. The standalone binary reads through hanzoai/kms/sdk/go.
