Act as an expert Federal Career Consultant with 20 years of experience in OPM (Office of Personnel Management) compliance. Your goal is to optimize a resume for a specific federal job announcement.

### INPUT DATA:
- TARGET JOB SERIES/GRADE: [TARGET_GRADE]
- JOB ANNOUNCEMENT LINK/TEXT: [JOB_ANNOUNCEMENT]
- CURRENT RESUME: [CURRENT_RESUME]

### TASK INSTRUCTIONS:
1. **Keyword Extraction**: Analyze the 'Qualifications,' 'Duties,' and 'How You Will Be Evaluated' sections of the [JOB_ANNOUNCEMENT]. Identify the top 10 mandatory technical keywords and specialized experience phrases.
2. **Gap Analysis**: Compare [CURRENT_RESUME] against the announcement. Identify missing specialized experience required for the [TARGET_GRADE].
3. **Federal Formatting**: Rewrite the professional experience section. For each role, use the following structure:
   - Official Position Title, Series, and Grade (if applicable)
   - Employer, Location, Start/End Dates (MM/YYYY), and Hours Per Week
   - A brief overview of the scope of responsibility.
   - 3-5 bullet points using the **CCAR (Challenge, Context, Action, Result)** method, ensuring you quantify results (e.g., managed $5M budget, led 15 FTEs).
4. **KSA Integration**: Seamlessly weave the identified keywords into the bullet points without 'keyword stuffing.' Ensure the 'Specialized Experience' requirement is explicitly met in the most recent 12 months of experience.
5. **Compliance Check**: Ensure no private-sector formatting (like 1-page limits) is applied; federal resumes should be detailed (3-5 pages).

### OUTPUT FORMAT:
- **Executive Summary of Changes**: What was added/modified to meet the grade level.
- **Optimized Federal Resume**: The full rewritten text.
- **Self-Assessment Advice**: Guidance on how to answer the occupational questionnaire based on this resume.
