 ## Project Overview

It provides an interface to the `expert_op4grid_recommender` library, allowing operators to simulate element disconnections, visualize network overflow graphs, and receive prioritized remedial action recommendations.

 ### Session Save/Load
 - **Save**: `buildSessionResult()` in `sessionUtils.ts` serializes all state (config, contingency, actions with status tags, combined pairs) -> `POST /api/save-session` writes to disk
 - **Load**: `POST /api/load-session` reads `session.json` -> frontend restores all state without re-simulating actions
-- **Output folder**: `<output_folder>/expertassist_session_<contingency>_<timestamp>/` contains `session.json` + overflow PDF
+- **Output folder**: `<output_folder>/costudy4grid_session_<contingency>_<timestamp>/` contains `session.json` + overflow PDF
 - **Interaction logging**: Every user interaction is logged as a timestamped, replay-ready event via `interactionLogger`. Saved as `interaction_log.json` alongside `session.json`.
 - See `docs/save-results.md` for session save/load and `docs/interaction-logging.md` for the replay contract

 ## Overview
 
-ExpertAssist logs every user interaction during a session as a timestamped, **replay-ready** event log. The log contains enough data for an automated agent (e.g. browser automation) to deterministically reproduce the exact same session — same clicks, same selections, same analysis runs — without human input.

The log contains enough data for an automated agent (e.g. browser automation) to deterministically reproduce the exact same session — same clicks, same selections, same analysis runs — without human input.

 ## Overview
 
-ExpertAssist renders pypowsybl Network Area Diagrams (NAD) for power grids with 11,000+ lines and 500+ voltage levels. At this scale, naive rendering causes multi-second tab switches, invisible line colors at zoom-out, and zoom lag/crashes. This document traces the critical rendering features, their rationale, and regression risks.
