Builder fit and maintenance synthesis

This report turns the accepted access, alternatives, and product records into a builder decision branch and proposed page-maintenance rules.

Scope: No new product, alternative, candidate, benchmark, or independent measurement was added. The synthesis uses the 20 Sep access record, the 22 Sep alternatives audit, and the 23 Sep product audit.

Builder decision branch

BranchUse it whenNext action
Pilot directThe task is a bounded Choice, Score, or Noul decision; a real account can obtain a key and credits; data terms are accepted; and a fallback exists.Pin jev-1.13.0. Start with synthetic or redacted state and record errors and fallback outcomes.
Route fallbackDirect TypeSafe access is blocked and OpenRouter'"'"'s account, logging, billing, and terms are acceptable.Use OpenRouter as a Jev access route. It is not a different open Jev model. Check the selected account and bill.
SubstituteThe blocker is the interface, local scoring/classification, or generation layer.Use system-one-adapter-python for an interface/provider substitute; SemIf for an experimental local readout; jevlike or GLiClass for a local scoring/classification workflow; or a structured-output LLM for schema/generation. None is verified Jev-model parity.
WaitEligibility, credits, price, quota, provider terms, or data controls are unknown.Keep the field unknown. Use synthetic or redacted state while the route is reviewed.
StopThe task needs open-ended writing or code, a deterministic policy, an automatic irreversible action, or no acceptable fallback. Stop also when the data route fails the workload rules.Keep a rule, human review, or another approved path.

Evidence gates

GateDated recordStatus
Task fitTypeSafe launch record and primitive documentation, checked 20 Sep 2026.Pass for a labelled, bounded Choice, Score, or Noul question. Stop for open-ended generation or deterministic policy. Unknown for accuracy, calibration, and error cost until a fixed workload is tested.
Route fitTypeSafe model record, API, OpenRouter listing, and Cloudflare model page, checked 20 Sep 2026.The documented direct shape passes. Account eligibility, credits, live quotas, gateway terms, Cloudflare price, and Vercel availability remain unknown.
SubstitutionThe six direct checks in runs/2026/09/12eff83e-6150-42af-a3bc-96f68a5c95ce/report.md, checked 22 Sep 2026.No verified open-weight Jev model was found in those checks. This is a bounded verification result, not proof that none exists.
Product evidenceThe direct-source audit in runs/2026/09/2c5550ce-7675-4864-9d81-63f0d6ac2060/report.md, checked 23 Sep 2026; see killmyidea and the other source links on the products page.No verified production product was found in the checked sources. killmyidea has direct Jev wiring and public-deployment metadata, but access and adoption remain unverified.

Proposed maintenance rules

Proposed rules, not measured analytics: apply the cadences below to the named fields. A provider, gateway, legal, deployment, release, or access change is an immediate trigger.
FieldsSource and last checkProposed cadenceIf stale or unreachable
Model ID, aliases, endpoint, access, price, limitsTypeSafe models, API, console, OpenRouter, Cloudflare, and Vercel; last check 20 Sep 2026.Every 7 days and before a pilot.Keep the dated historical value, mark the current field unknown, and do not call an alias a reproducible pin.
Data, logging, retention, and termsTypeSafe legal index, MCA, privacy policy, DPA, and the selected gateway/proxy terms; last check 20 Sep 2026.Every 14 days and before sensitive data.Mark current terms unknown and block sensitive-data guidance until reviewed.
Alternatives statusThe six direct sources listed in the 22 Sep alternatives report.Every 30 days or after a source release/change.Keep the row, mark current status unknown, and remove unverified current parity, licence, price, or maintenance claims.
Product evidence and adoptionThe direct repositories and host check listed in the 23 Sep product report.Every 30 days or after a deployment, customer, operator, or usage claim.Keep the bounded “not verified in the checked sources” statement; mark live access and adoption unknown.

No independent measurement

No independent workload measurement, common comparison, or authenticated Jev call was run. TypeSafe'"'"'s latency and price are vendor claims. SemIf'"'"'s warm RTX 3090 timings exclude model loading and result writes and are not a Jev comparison. The product audit found no independent usage or production measure. Live performance, accuracy, calibration, and fallback success remain unknown.

If a builder supplies a fixed workload later, pin the model and route, freeze state and questions, count tokens, define cold and warm runs, repeat labelled cases, and record latency, cost, errors, decision quality, calibration, and fallback outcomes.
