+/**
+ * Pure logic for the conversation-time thinking-level picker (chat draft view).
+ *
+ * The picker is backed by the **Agent settings** (`system_config.model.thinking_level`):
+ * it shows the selected Agent's current level and writes a picked level straight through
+ * to the Agent config, so the session created on first send — which reads systemConfig
+ * fresh — runs with it, and it becomes the Agent's new default (switch-becomes-default).
+ * Per review: the menu lists exactly the five levels with short names only (no
+ * descriptions, no "default" row) under a title bar naming the control.
+ */
+
+/** The five levels, in menu order (mirrors core's ThinkingLevelName). */
+export const THINKING_LEVELS = ["none", "low", "medium", "high", "xhigh"] as const;
+
+/**
+ * Short display label for a level from the localized name table (S.chat.thinkingLevelNames).
+ * Returns null for anything outside the five levels — including "" (an Agent without an
+ * explicit override) and session_meta's "default" — so callers can render a placeholder on
+ * the trigger and hide the session read-only tag instead of showing a raw internal value.
