dsh-session-slm-router

dsh-session-slm-router

Shadow-mode SLM router plugin for DeepSeek Harness. Per-turn weak/strong prediction via the vertical-small-model CLI; writes a shadow JSONL log without changing the active session model (S1 only).

⚠️ S1 — default shadow mode: observe only, no model switching. weak-only mode (S3 grayscale) allows downgrade-to-weak switches but does not persist the user's original model.
