From 9afeb1a6d264da8b59d8d5103ae4a1c6b8ad5441 Mon Sep 17 00:00:00 2001 From: Darko Luketic <201112286+dlukt@users.noreply.github.com> Date: Sat, 19 Sep 2026 15:00:24 +0200 Subject: [PATCH 1/3] Make the Jev backend provider-agnostic (TypeSafe direct + Vercel AI Gateway) (#1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * refactor: move TypeSafe API behind a provider class TypeSafeJevProvider now implements JevPort; createSdkAdapter and classifyError keep their names and behavior. The SDK client is injectable so provider tests need no network. * feat: add Vercel AI Gateway Jev provider and JEV_PROVIDER selection VercelJevProvider translates Jev questions/answers to the gateway evaluation API (typesafe-ai/jev) via experimental_evaluate from the ai package. JEV_PROVIDER=typesafe (default) | vercel, validated at startup; each provider owns its classifier. Confidence absent from gateway answers is derived from the distribution (selected-choice mass / max level mass). * test: cover Jev providers and provider selection 22 tests: provider selection and startup failure, TypeSafe request forwarding and error mapping, Vercel question/answer translation, confidence derivation, padding, model-id reporting, missing keys, CLI-level JEV_PROVIDER behavior, and provider-independent review behavior. All network calls mocked. Docs: provider configuration in README and architecture.md. * fix: enforce the executor timeout in the Vercel provider experimental_evaluate has no timeout parameter, so the provider wraps the call in its own AbortController: a timer aborts at timeoutMs and forwards an external run signal, surfacing as AbortError/TimeoutError which classifyVercelError maps to aborted/transient. * fix: preserve TypeSafe confidence, bind gateway credentials, and secure defaults - Read TypeSafe's separate confidence statistic from providerMetadata.typesafe.confidence[questionId] (Choice/Score); derive from the distribution only when that metadata is genuinely absent, documented as an approximation. - createVercelAdapter now binds the supplied AI_GATEWAY_API_KEY via createGateway({apiKey}).evaluationModel(id) instead of relying on the process-global gateway; process.env is never mutated. Proven by a local-server test asserting the Bearer header actually sent. - Model namespaces stay separate: unqualified TypeSafe ids (jev-1.13.0) select the configured gateway model (JEV_GATEWAY_MODEL, default typesafe-ai/jev); slash-qualified gateway ids pass through. - gateway.zeroDataRetention=true by default (evaluations contain source code); JEV_GATEWAY_ZERO_DATA_RETENTION=0 opts out. - Already-aborted external signals now propagate before any evaluation. - Optional live smoke: npm run smoke:vercel (JEV_SMOKE=1), skips cleanly. - README/help updated to match actual behavior. * fix: tighten Vercel provider bookkeeping and smoke gating - ask() computes the effective gateway model once and uses it for both the model factory and the response.model fallback. - smoke-env JEV_SMOKE regex anchored as a group; '10', 'yes1', 'true1' no longer enable live smoke tests (covered by tests). - createVercelAdapter accepts test-injection options (baseURL, evaluate) so the credential test drives the adapter itself end-to-end against a local server; the Bearer assertion is unchanged. * fix: address review findings on budget accounting, classifier coupling, retries - P1: missing gateway usage no longer zeroes the input-token budget; the envelope reports the same deterministic estimate the executor reserved, so --max-input-tokens keeps guarding Vercel runs. - P2: createWorkflowDependencies now accepts a provider name and maps it through classifierFor; jevFromEnvironment(env) callers can no longer pair a Vercel port with the TypeSafe classifier. The CLI passes configuredProvider(io.env) directly. - P2: malformed gateway answers (missing/wrong-typed) throw ValidationError instead of plain errors, so the executor routes them through its invalid-response retry path instead of failing the frame. - Test env-leak hardening: the credential test asserts process.env is unchanged across construction rather than assuming the var is unset. * fix: address round-2 review findings on retries, classifier derivation, aborts - P2: malformed gateway answers now return a valid envelope with an empty answer map instead of throwing: the executor's response- validation path (which retries) rejects it via the frame parser, rather than the transport-error path (unknown, never retried). Verified end-to-end: a frame with a validating parser gets its configured retries (3 attempts with retries: 2). - P2: createWorkflowDependencies now derives the default classifier from the port itself (VercelJevProvider.classifyError) instead of an independent provider-name default, closing the two-argument pairing gap; the CLI returns to the two-argument call. - P2: caller-supplied abort reasons are normalized to abort-typed errors (DOMException AbortError) when forwarded and when thrown for an already-aborted signal, so classifyVercelError reports aborted instead of unknown. * fix: address round-3 review findings on transient failures and answer keys - P2: classifyVercelError recognizes plain connection failures as transient — TypeError: fetch failed (with ECONNREFUSED/ENOTFOUND/ EAI_AGAIN/ECONNRESET/EPIPE on the cause), retryable-flagged AI SDK errors, and network error names. - P2: unexpected gateway answer keys are no longer silently dropped; translation rejects and the empty-answer envelope routes the frame into the invalid-response retry path. - P3: README now documents the conservative input-size estimate reported when gateway usage is absent. * fix: address round-4 review findings on key validation and classifier binding - P2: answer-key unexpectedness uses Object.hasOwn, so prototype-named keys (constructor, toString) count as unexpected instead of passing through the inherited-property 'in' check. - P2: extra probability labels reject instead of being silently dropped — choice answers with probabilities for unknown choices and score answers with out-of-range level keys both route into the invalid-response retry path. - P2: defaultClassifierFor binds the port's classifyError to the port, so method-reference invocation through WorkflowDependencies keeps the right 'this'. * fix: address round-5 findings — canonical score keys, bound classifier, README accuracy - P2 (real miss caught by review): the round-4 classifier bind never landed (heredoc failure silently dropped it from that commit). defaultClassifierFor now genuinely binds the port's classifyError to the port; regression test invokes it through the dependencies layer and asserts instance state stays reachable. - P2: score probability keys are compared against exact canonical level keys ('0'..'n-1'), so '1.5', '01', '1e0' reject instead of coercing into range and being silently dropped. - P2: privacy guidance now discloses that the Vercel provider routes through the AI Gateway, which processes requests even under zero-data-retention; users are pointed at both services' terms. - P3: provider section no longer promises identical results across providers (confidence fallback can differ); describes shared schema and capability instead. - P3: requirements/setup are provider-neutral (either TypeSafe key or gateway key per JEV_PROVIDER). * fix: address round-6 findings — choice synthesis, env redaction, smoke pinning, docs - P2: choice answers that omit probabilities (an allowed gateway shape) now synthesize a point mass on the selected choice instead of an all-zero distribution that readChoice would reject, burning every retry on otherwise valid answers. - P2: redaction is env-aware — createRedaction(env) unions the supplied and process environments' credential values, and createWorkflowDependencies threads io.env through, so a custom environment's gateway key is redacted from evidence and errors. - P2: smoke-real forces JEV_PROVIDER=typesafe so the TypeSafe smoke never silently exercises Vercel (or fails parsing its error packet) when a gateway env is present. - P3: the workflow overview is provider-neutral (TypeSafe key or gateway key per JEV_PROVIDER). * fix: synthesize score distributions when probabilities are omitted - Score answers without probabilities (an allowed gateway shape) now get a distribution consistent with the reported score: point mass for integral scores, linear interpolation between adjacent levels for fractional ones (readScore accepts and expects both). Previously the all-zero fallback was rejected by readScore and burned every retry on valid answers. - Out-of-range scores (beyond the rubric) still reject into the invalid-response retry path; bounds match readScore's tolerance. - Regression tests cover integral, fractional, and out-of-range cases. * fix: redact port-owned credentials in the two-argument composition - Ports expose credentialSecrets (TypeSafeJevProvider and VercelJevProvider both populate them); portSecrets(jev) reads them. - createWorkflowDependencies unions the port's credentials into the redaction dependency, so createWorkflowDependencies(root, createVercelAdapter(customEnv)) scrubs the custom-env key from evidence and errors even though no environment was passed. - createRedaction(env, extraSecrets) accepts the extra values. - Tested for both providers through the plain two-argument call. --- README.md | 67 ++- docs/architecture.md | 8 +- package-lock.json | 123 ++++- package.json | 5 +- scripts/smoke-env.ts | 24 + scripts/smoke-real.ts | 2 +- scripts/smoke-vercel.ts | 47 ++ src/adapters/config.ts | 43 +- src/adapters/dependencies.ts | 34 +- src/adapters/jev.ts | 71 ++- src/adapters/redact.ts | 28 +- src/adapters/vercel-jev.ts | 393 ++++++++++++++ src/cli.ts | 24 +- src/index.ts | 26 +- src/workflows/run.ts | 4 +- test/providers.test.ts | 958 +++++++++++++++++++++++++++++++++++ 16 files changed, 1802 insertions(+), 55 deletions(-) create mode 100644 scripts/smoke-env.ts create mode 100644 scripts/smoke-vercel.ts create mode 100644 src/adapters/vercel-jev.ts create mode 100644 test/providers.test.ts diff --git a/README.md b/README.md index 206d382..b92a845 100644 --- a/README.md +++ b/README.md @@ -35,7 +35,8 @@ A common agent flow asks jev-code to find relevant files before editing, check c it into small, size-limited pieces, such as one changed block of a file or one failure from a log. 3. **Exact checks run first.** Plain rules catch things like an added `test.skip`, deleted assertions, deleted test files, and lockfile, CI or config changes. -4. **Jev answers fixed-choice questions about each piece.** Using your required TypeSafe API key, jev-code asks +4. **Jev answers fixed-choice questions about each piece.** Using your Jev credential (TypeSafe API key, or + an AI Gateway key with `JEV_PROVIDER=vercel`), jev-code asks [TypeSafe Jev](https://typesafe.ai), a model that answers multiple-choice questions, about one small piece at a time.
