+When writing your script, you MUST follow these expert business rules:
+1.  **Linking Datasets Rule:** If you need to connect facilities to health zones when the 'zone' column is not in the facility list,
+    you must first identify the high-priority zone from the beds data, then find the major city (by facility count) in the facility list,
+    and *then* assess that city's capacity. Do not try to filter the facility list by a 'zone' column if it does not exist in the schema.
+2.  **Prioritization Rule:** To prioritize locations, you MUST combine the most recent population data with specific high-risk health indicators
+    to create a multi-factor risk score.
+3.  **Capacity Calculation Rule:** For capacity over a 3-month window, assume **60 working days**.
+4.  **Cost Calculation Rule:** Sum 'Startup cost' and 'Ongoing cost' per person before multiplying.

---- END SCENARIO ---
+{EXPERT_ANALYTICAL_GUIDELINES}
 
 --- DATA SCHEMA ---
 {schema_context}
 --- END DATA SCHEMA ---
 
-You must follow a rigorous three-step "Map, Plan, Execute" process:
-
-**Step 1: Map Concepts to Data.**
-First, analyze the user's scenario and the provided data schemas. Identify the key business concepts (e.g., "hospitals", "sales", "regions") and metrics (e.g., "wait times", "revenue", "population"). Then, create a logical mapping from these concepts to the actual column names in the provided DataFrames. State these mappings clearly. This is the most critical step to ensure your analysis is relevant.
-
-**Step 2: Create a Detailed Analysis Plan.**
-Based on your mapping, formulate a step-by-step plan. Describe the data cleaning, merging, grouping, and aggregation steps needed to answer the user's request using the columns you identified.
-
-**Step 3: Write the Python Script.**
-Based on your plan, write a complete Python script.
-
-CRITICAL SCRIPTING RULES:
-1.  **DYNAMIC DATAFRAME IDENTIFICATION:** Your script MUST identify the correct DataFrame by checking for the presence of the columns you mapped in Step 1. Do NOT use hardcoded indices like `dfs[0]`.
-2.  **ROBUST SUCCESS CHECK (MOST IMPORTANT TO PREVENT AMBIGUITY ERROR):** After attempting to find a DataFrame, you MUST check for success by comparing the result to `None`. Do NOT use `if not my_dataframe:` as this is ambiguous.
-    ```python
-    # Good, robust code
-    def find_df_by_cols(dfs, required_cols):
-        for df in dfs:
-            if all(col in df.columns for col in required_cols):
-                return df
-        return None
-
-    primary_df = find_df_by_cols(dfs, ['user_id', 'transaction_amount'])
-    
-    # This is the correct way to check for failure
-    if primary_df is None:
-        raise ValueError("Could not find the primary dataframe based on its columns.")
-    ```
-3.  **VERIFY COLUMN EXISTENCE:** Only use columns that you have explicitly identified and mapped.
-4.  **NO FILE READING:** The data is already in the `dfs` list.
-5.  **STRICTLY JSON OUTPUT:** The script's ONLY output must be a single JSON object.
-6.  **ROBUST & GENERIC:** Write robust code that can handle potential missing data (`errors='coerce'`, checking for `None`).
-
-Now, provide your response in the following format:
-
-**ANALYSIS PLAN:**
-```text
-**1. Concept-to-Column Mapping:**
-- Concept: [e.g., 'Hospitals'] -> Mapped Column: [e.g., `Facility`]
-- Concept: [e.g., 'Surgical Wait Time'] -> Mapped Column: [e.g., `Surgery_Median`]
-
-**2. Step-by-Step Analysis:**
-1.  **Data Identification:** [e.g., "Define a helper function to find dataframes by checking for key columns..."]
-2.  **Data Cleaning:** [e.g., "Convert metric columns to numeric..."]
-3.  **Analysis Step A:** [e.g., "Group the primary dataframe by the 'Facility' column and calculate the mean of the 'Surgery_Median' column..."]
-4.  ... 
-
-the final JSON object]
-
-# Your complete Python script starts here
-import pandas as pd
-import json
-import re
+CRITICAL RULES:
+1.  **DO NOT READ FILES:** You MUST NOT include `pd.read_csv`. The data is ALREADY loaded in the `dfs` variable. You MUST use this variable. Failure to do so will cause a fatal error.
+2.  **JSON OUTPUT ONLY:** Your script's ONLY output must be a single JSON object printed to stdout containing the raw data findings.
+3.  **BE PRECISE:** Use the exact, case-sensitive column names from the schema and robustly clean strings (`re.sub()`) before converting to numbers.
+4.  **JSON SERIALIZATION:** Before adding data to your final dictionary for JSON conversion, you MUST convert any pandas-specific types (like `int64`) to standard Python types using `.item()` for single values or `.tolist()` for lists.

-You must write a final report that follows this exact structure:
-
-**### Executive Summary**
-- Start with a brief paragraph summarizing the core problem, key findings, and top recommendations. This should be a high-level overview for a leadership audience.
-
-**### 1. [First Key Finding, e.g., Hospitals with the Longest Wait Times]**
-- Present the relevant data in a Markdown table.
-- Write a short narrative interpreting the data. What does it mean? Are there any outliers? Why might these facilities have long waits (e.g., specialized care, rural location, capacity issues)?
-
-**### 2. [Second Key Finding, e.g., Specialties with the Longest Wait Times]**
-- Present the relevant data in a Markdown table.
-- Interpret the findings. Why are these specialties facing delays (e.g., specialist shortages, equipment needs)?
-
-**### 3. [Third Key Finding, e.g., Zone-Level Performance]**
-- Present the data in a table, including a comparison to a relevant average or baseline.
-- Analyze the geographic or systemic issues this data reveals.
-
-**### 4. [Fourth Key Finding, if applicable, e.g., Geographic Distribution]**
-- Synthesize location data with the wait-time findings.
-- Discuss the implications for patient equity, travel burdens, and access to care.
-
-**### 5. Recommendations for Resource Allocation**
-- Provide specific, actionable, and justified recommendations.
-- Structure them by category (e.g., by facility, by specialty, by zone).
-- For each recommendation, provide a clear rationale directly linked to the data findings above (e.g., "Allocate additional resources to Glace Bay Hospital because it is a rural facility in a high-wait zone, suggesting a capacity bottleneck.").
-
-**### Data Limitations**
-- Briefly mention any potential limitations of the analysis (e.g., missing data, use of proxies, case severity not included). This adds credibility to the report.
-
-Do not just repeat the JSON data. Your value is in interpreting the numbers, connecting the dots between different findings, and providing clear, data-backed strategic advice.

+1.  Follow the "Expected Output Format" requested by the user.
+2.  Use tables, bullet points, and DETAILED narrative justifications for each recommendation.
+3.  Synthesize the raw data into actionable insights. Do not just copy the raw numbers; interpret them.
