Jev: second full-scope source pass

Direct-source update to the earlier full rebuild. Newly found projects are discoveries on 25 September, not proof they were created in the preceding 24 hours. Earlier reports remain dated snapshots.

Result: more Jev integration paths and independent model artifacts are documented, but no audited product was independently verified operating in production. No authenticated Jev call, bill or same-workload benchmark was run.

New project evidence

Project and direct sourceEvidence / formRole and limit
JevmailB · Gmail applicationRead-only OAuth; Vercel Jev sorts trays and urgency. No-key preview simulated; speed/cost author estimates.
DocJevB · document applicationExtract text then category/split judgment; optional cloud OCR changes data path. Comparison excludes OCR time.
Jev Comment TriageB · WordPress applicationHolds comments, retries failures, human fallback. Default author identity fields sent; speed/accuracy author-run.
Jev for ChromeB · browser extensionChooses observed actions/targets. Store listing proves distribution, not task success or active users.
Jev TradeB/C/P · high-risk live claimCreator claims live fills; default MODEL=mock and keyless mode dry-run. Public desk was Offline, positions blank; no live Jev call or order verified.
Project and direct sourceEvidence / formRole and limit
pg-jevB · Postgres extensionSQL judgments require plpython3u/superuser; row data may leave host. Author batch tests degrade at larger sizes.
sqlite-jevB · SQLite extensionBatched jev_rows and max_rows guard; calls TypeSafe, not a local model.
sqlite3-jevA · distinct SQLite C extensionDirect libcurl source path; SQL input may leave local database.
WordPress AI Provider for JevB · provider pluginServer key and authenticated REST/PHP primitives. Manual install; fallback differs from separate comment plugin.
jev-reranker CLIB · retrieval CLIReranks JSON candidates; answer still needs source verification.
Python jev-rerankerB · distinct RAG libraryConcurrent passage reranking; no independent retrieval gain measured.
Jev WorkbenchB/C · local judgment serviceHTTP/MCP functions; no-key demo simulated; maintainer claims keyed test. No idempotency/retry protection.
TypeSafe routerA/C · official-repo exampleServer Choice call and review fallback; no-key demo uses mockCallJev. Not customer deployment.
computer-use-jevB · macOS prototypeAccessibility target/action selection with stops; fake-worker tests do not prove live task success.
jev-androidB · Android SDK/sampleRechecks controls and action policy; DONE unverified absent host OutcomeVerifier. API unstable.
Jev LogsB/C · observabilityVercel live mode but default fixed offline demo; evidence note says live test skipped. Savings modelled.
openclaw-typesafe-aiB · optional agent tooltypesafe_decide calls direct endpoint; no installation/adoption proof.
omp-jevens-classifierB · permission gate prototypeCritical patterns, env and call failures still prompt. Judgment is not authorization.

A = inspected call path; B = first-party documentation; C = mock/simulation; P = author live-use claim. These describe evidence, not deployment. Older projects remain in the products inventory.

Alternatives by layer

Independent model artifacts include Kev, CLM, Open-Jev (Zefan-Cai), system-one (mpuig), NanoJev. A Jev-shaped endpoint does not mean TypeSafe weights or equivalent calibration. LocalJev generates JSON probabilities, not direct logit readout. GPT-AGI/OpenJev starts with a mock and has no shipped endpoint or trained head; it is distinct from Zefan-Cai/Open-Jev. Jeff/GliFormer is distinct from Gestalt-Lab Jeff. Check the layered matrix for licences and limitations.

Use-case boundaries

Project examples include read-only Gmail triage, WordPress comment review, SQL row judgments and document splitting. The official semantic-find cookbook pairs line Choice with answer-presence Noul because Choice alone must pick a line. Candidate extraction chooses observed spans; absent values and exact date logic stay in code. Citation checks are review signals, not independent source verification.

Preceding 24 hours: bounded monitor

Window: 24 September 18:20 to 25 September 18:20 UTC. Scans began 17:39 UTC on 25 Sep, so initial searches included a 41-minute wider superset. Relative dates and cache gaps do not establish exact-hour changes. AgentRun Show HN may be inside the window, but exact source time and live Jev calls remain unresolved. Laya model API shows 24 Sep 05:39:22Z, outside this window. GitHub topic shows date-only 25 Sep updates for AnyJev/JevAny, not exact content or hour.
