fix(proxy): invoke onPayment after confirmed settlement (rebase of #325) - #330

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Settlement callbacks may report an empty model for Request-based calls, while an async callback failure can become an unhandled rejection after payment. These issues should be fixed before enabling the new notifications. Sequence Diagram(s)sequenceDiagram

- Line 110: Update the request-model preparation in the FetchFn flow to parse
request.clone() when init?.body is absent, while preserving the existing
init?.body handling; ensure notifyAcceptedPayment receives the parsed model for
Request inputs and add a regression test covering new Request(...) without init.
- Line 109: Update notifyAcceptedPayment and both onPayment callback contracts
to support void or Promise<void>, and attach a non-awaited rejection handler to
each observer invocation so asynchronous failures are handled without changing
settlement flow. Add coverage for an observer that rejects asynchronously.

Handle rejected asynchronous observers.
The synchronous try/catch in notifyAcceptedPayment does not handle a rejected Promise from an async onPayment observer. The ignored rejection can become unhandled after settlement. Change both callback contracts to void | Promise<void>, attach a non-awaited .catch(...), and add a test for an asynchronously rejected observer.

Parse the request body for Request inputs.
requestModel is assigned only in the if (init?.body) branch. When FetchFn receives new Request(... ) without init, the request body remains valid, but notifyAcceptedPayment sends model: "" after the paid response. Parse request.clone() when init?.body is absent, and add a regression test for this call form.

Supersedes #325 — same commit, authored by @twzrd-sol, rebased onto
main. Opened here because #325's head is on a fork and a rebase needs a force push GitHub will not let a maintainer make.Closes #321.
ProxyOptions.onPaymentis declared atsrc/proxy.ts:1533and was invoked nowhere. This puts the notification at the layer that owns both paid paths (normal 402 → signed retry, and cached pre-auth → paid first request), gated on the v2PAYMENT-RESPONSE/ v1X-PAYMENT-RESPONSEsettlement header. A rejected 402 does not fire it, and an observer that throws cannot turn a paid response into a retry.What changed in the rebase
mainlanded the API-key rail (v0.12.268), which routesauthMode === "api-key"aroundcreatePayFetchWithPreAuthentirely.onPaymentis wired on the wallet branch only, with a comment saying why: the API-key rail is billed server-side against account credit, so there is no per-request settlement for an observer to report.Known gap, not fixed here
createApiKeyFetch(src/api-key.ts:166-179) still never notifies. After this lands the documented callback works for wallet users and stays silent for card-funded ones. Worth a follow-up issue.Verification (on the rebased tree, merged with the #322 successor)
npm run typecheck,npm run lint: cleannpm test: 982 passed, 1 skipped, 0 failednpm run build+ dist smoke: passnpm run test:e2e: 20 passed, 1 skipped, 0 failednpm run test:e2e:tool-ids: proxy boots, binds, closes cleanLive-paid e2e skipped (empty wallet). One thing still unproven: no live evidence BlockRun's gateway actually emits the settlement header — the test gateway fabricates it. If it does not, this is inert and every test still passes. A single ~$0.003 probe settles it.
