Don't fall through to API-only when Jev is unsure — JEV Brief · Oct 4
Nothing TypeSafe-official moved the contract today. The useful noise is route floors: azumag/docich #1648 (open draft) puts Jev between api_only and web/code investigation, and AEALab/RefractRouter #173 (open) adds Jev split discrimination before auto-routing. If you only have four minutes, keep unsure Jev classifications off the cheap API-only fast path, then scan Top Repos.
- Don’t fall through to API-only when Jev is unsure — pin ≥0.80 and fail closed on timeout/unknown. docich #1648 (open draft) routes chat with Jev between
api_onlyvs read-only web/code investigation. Hard floors: API-only only when confidence is ≥ 0.80; timeout, low confidence, invalid, and unknown must not fall through to API-only; secrets fail closed before the provider; the Jev prompt strips persona/memory. Quiet-day Pro move: treat unsure System One labels as “investigate,” never as permission to take the cheap write path. - Split discrimination before auto-routing — zero-call precheck first. RefractRouter #173 (open) tightens the auto-route model catalog and adds Jev split discrimination plus a zero-call precheck before wiring. Same shape as docich: decide whether the cheap path is even eligible before you spend tokens or hit a provider.
- Watchlist only — not Based, not contract moves. wh000wh000/awesome-jev-live (~178 stars) is an evidence-graded index of TypeSafe System One doors (rebuilds every 2 hours). mc9max/jevos is a new 0-star CPU-only OSS alternative — not TypeSafe Jev. silex-ai-lab/jev-runtime-observability defaults to open-source Kev, not TypeSafe Jev. Do not re-lead on yesterday’s anvil #38 / standard-reader #192.

Live board: https://jev.pro/top-repos. Stars are public rank, not a quality award. Metrics still sit on the 2026-09-21 snapshot (midnight refresh has not moved), so 1-day deltas are flat and the tables show stars only.

Ultrafast still leads Jev-Based; QuantDinger still leads Integrations. Treat the alternatives track as local-door reading (Laya / NanoJev / Kev / von / jevos) — star rank is not a swap for TypeSafe Jev.
What moved
Nothing TypeSafe-official that changes the contract, model pin, price, or channel door. Reddit collect returned 403 (empty). HN still carries Luna Decision API / Decision Index competitive framing from prior days — already covered; not a fresh TypeSafe ship.
Worth one click
