+"""AgentTrace — MatchDay's visible proof of agentic behavior (Best Agent).
+
+A MatchDay turn is genuinely multi-step: the Brain (Nemotron) extracts intent,
+grounds the match against verified WC2026 fixtures, picks tools, and Python
+(Hands) executes every API call and scores every price. Until now that decision
+chain lived only in logs / a disk JSONL trace (``record_trace.py``). This module
+captures it in one structured record that renders *in the live UI*, so a judge
+can see the agent actually reasoned — intent → grounding → multi-step tools →
+evidence → ranking formula → fallback status — not a static page.
+
+It adapts (reference-patterns-notes.md, the "Best Agent / production
+architecture" docs — NOT Layla, which is product-flow only):
+  - §3 TurnContext: intent → trip_request → api_results → scored_packages.
+  - §6 typed streaming events (presentation = transport, never truth).
+  - §9 FailoverReason taxonomy (status as a small enum, not free text).
+  - §5 code-enforced green-light (intent validated before green-light).
+
+Pure data, no I/O, no LLM. Accumulated by ``agent_loop`` (tool calls) and
+``app.py`` (intent/grounding/evidence/ranking/mode), then serialized by
+``render.render_trace`` into a collapsible, JS-free ``<details>`` panel + a
+``#md-trace`` JSON island. Every setter is defensive (best-effort; never raises)
