From 91dc4414f9d7b378d8109e5550b355e51c300533 Mon Sep 17 00:00:00 2001 From: Tin Chi Lo Date: Sat, 26 Sep 2026 20:07:29 -0700 Subject: [PATCH 1/7] feat(auto-router): Bespoke Nimble as a Jev classifier provider jev_classifier_config.provider selects typesafe (default) or bespoke_nimble, a self-hosted server on the same /v1/systemone API. The provider picks the env credential pair, the default base, whether a key is required and the log/cost prefix. Nimble may run keyless and never receives an env key at a config-set base. Dashboard saves carry the stored provider forward.
