-## Picking the advisor in the composer
+## Per session, off by default
+
+The advisor is chosen **per session**. Every session, new or existing, starts with the advisor **off**. Turning it on, or picking a model, in one session doesn't affect any other.
 
 The plugin adds an **Advisor** control to the composer bar, next to the model picker:
-- **Off**: no reviews.
-- **Same model as the agent**: the default.
+- **Off**: no reviews. This is the default.
+- **Same model as the agent**: turns it on with the session's own model.
 - **Any model from DSH's model picker**: the same provider-grouped list. **Hover** a model that has reasoning efforts to open a side menu and pick its effort; clicking the model uses its default effort. The keyboard works too (→ opens the effort menu, ← goes back, Esc closes).
 
-The trigger shows the current choice, e.g. `Claude Haiku · Low` or `Advisor off`. The choice is saved on the host (`<profile>/omp-advisor.json`, through `GET`/`POST /omp-advisor/settings`). It applies from the advisor's next review, with no restart, and it overrides `enabled`, `provider`, `model` and `reasoningEffort` from the config below. Picking an advisor never changes the agent's own model.
+The trigger shows this session's choice, e.g. `Claude Haiku · Low` or `Advisor off`.
+- **Where it's saved:** on the host in `<profile>/omp-advisor/sessions.json`, keyed by session id, through `GET`/`POST /omp-advisor/settings?session=<id>`. The newest 2,000 sessions are kept.
+- **When it applies:** from that session's next review, with no restart.
+- **What it overrides:** `enabled`, `provider`, `model`, `reasoningEffort` and `minLevel` from the config below, for that session only.
+- **What it never touches:** the agent's own model.
+
+Upgrading from 1.1: the old global `<profile>/omp-advisor.json` is ignored, so no session stays on without being turned on again.

-    enabled: true
+    enabled: false        # default for sessions that haven't been switched on in the composer
     provider: ''          # advisor model route; empty = same as the agent
     model: ''             #   e.g. provider: omni, model: claude-haiku-4-5 for a cheap fast reviewer
     reasoningEffort: ''   # optional effort for the advisor model
