[2f988f42] fix(company-explorer): Implement robust quantitative potential and atomic opener generation\n\n- Refactored ClassificationService for two-stage metric extraction (direct area and proxy).- Enhanced MetricParser for targeted value matching and robust number parsing.- Implemented persona-specific 'Atomic Opener' generation using segmented pains.- Fixed logging configuration and Pydantic response models.- Added dedicated debugging script and updated documentation (GEMINI.md, MIGRATION_PLAN.md).

     **Troubleshooting:**
     *   **"BaseModel" Error:** Usually a mix-up between Pydantic and SQLAlchemy `Base`. Check imports in `database.py`.
     *   **Missing Dependencies:** The CLI agent runs in `/app` but not necessarily inside the container's venv. Use standard tools (`grep`, `sqlite3`) where possible.

+## Critical Debugging Session (Feb 21, 2026) - Re-Stabilizing the Analysis Engine
+
+A critical session was required to fix a series of cascading failures in the `ClassificationService`. The key takeaways are documented here to prevent future issues.
+
+1.  **The "Phantom" `NameError`:**
+    *   **Symptom:** The application crashed with a `NameError: name 'joinedload' is not defined`, even though the import was correctly added to `classification.py`.
+    *   **Root Cause:** The `uvicorn` server's hot-reload mechanism within the Docker container did not reliably pick up file changes made from outside the container. A simple `docker-compose restart` was insufficient to clear the process's cached state.
+    *   **Solution:** After any significant code change, especially to imports or core logic, a forced-recreation of the container is **mandatory**.
+        ```bash
+        # Correct Way to Apply Changes:
+        docker-compose up -d --build --force-recreate company-explorer
+        ```
+
+2.  **The "Invisible" Logs:**
+    *   **Symptom:** No debug logs were being written, making it impossible to trace the execution flow.
+    *   **Root Cause:** The `LOG_DIR` path in `/company-explorer/backend/config.py` was misconfigured (`/app/logs_debug`) and did not point to the actual, historical log directory (`/app/Log_from_docker`).
+    *   **Solution:** Configuration paths must be treated as absolute and verified. Correcting the `LOG_DIR` path immediately resolved the issue.
+
+3.  **Inefficient Debugging Loop:**
+    *   **Symptom:** The cycle of triggering a background job via API, waiting, and then manually checking logs was slow and inefficient.
+    *   **Root Cause:** Lack of a tool to test the core application logic in isolation.
+    *   **Solution:** The creation of a dedicated, interactive test script (`/company-explorer/backend/scripts/debug_single_company.py`). This script allows running the entire analysis for a single company in the foreground, providing immediate and detailed feedback. This pattern is invaluable for complex, multi-step processes and should be a standard for future development.
