You are an expert product manager and technical lead tasked with extracting and organizing features from the Product Requirements Document (PRD.md, or the PRD provided in the conversation).

Create a comprehensive FEATURES.md file that clearly outlines all features, organized by priority and category. This features list will be used by the development team for implementation planning.

If PRD-REVIEW.md exists, read it too. Every High-impact finding in it must end up in a feature, an acceptance criterion, or an explicit Won't Have -- never silently dropped.

If any critical information is missing or unclear, ask specific questions before proceeding.

Extract and organize the features by:

1. FEATURE IDENTIFICATION AND CATEGORIZATION:

• Extract all explicit and implicit features from the PRD
• Ensure each feature is discrete, specific, and implementable
• Assign a unique identifier (e.g., F1, F2, F3)
• Group by logical category (e.g., User Authentication, Dashboard, Reporting)
• Distinguish core features from enhancements
• Tag by user persona where applicable

2. PRIORITIZATION:

• Apply MoSCoW prioritization to each feature:
• Must have: Critical for the minimum viable product
• Should have: Important but not critical for initial release
• Could have: Desirable but can be deferred
• Won't have: Out of scope for current release but noted for future
• Consider dependencies between features when prioritizing

3. FEATURE DETAILING:

• Clear, concise description for each feature
• Acceptance criteria
• Technical considerations or constraints
• Potential edge cases or special handling requirements

4. IMPLEMENTATION COMPLEXITY:

• Relative complexity for each feature (Low, Medium, High)
• Features requiring third-party integrations or special expertise
• Features that may present significant technical challenges

Write every feature as a row in a table with these columns: `| ID | Feature | Priority | Source | Complexity | Acceptance Criteria |`. Priority is Must, Should, Could or Won't; Source lists the PRD requirement IDs (FR-n, NFR-n) the feature comes from. Every PRD requirement must be the source of at least one feature or be listed as Won't Have, and every out-of-scope item in the PRD gets a Won't Have row. Group the tables by category.

First, provide a brief overview of the product based on the PRD. Then create the FEATURES.md content with a summary section showing feature counts by priority and category.

If FEATURES.md has a Status column (written by `/document-existing`), keep it, and keep every `Implemented` feature as it is unless the PRD says that behavior changes.

Feature IDs are permanent. If FEATURES.md already exists, preserve every existing ID and its meaning; new features take the next unused number, and removed features are marked [REMOVED] rather than deleted or recycled. Never renumber -- the RFCs cite these IDs by number.

SELF-CHECK BEFORE FINISHING

• Recount every summary table from the actual content. Never carry a count forward from earlier in your own output.
• Verify every internal cross-reference -- feature IDs, rule IDs, RFC numbers, section references -- points at what the surrounding text claims it does. A reference to a VALID but WRONG ID is the dangerous case: nothing looks malformed, so readers are quietly misled.
• Confirm no two tables in the document disagree with each other.
• If `trace-check.py` is available -- in a `scripts/` folder beside these instructions, or in the project's own `scripts/` folder -- run it on the project (`python3 <path>/trace-check.py .`) and fix every FAIL it reports. It checks IDs, coverage and dependencies mechanically, which reading cannot do reliably.
• State that you ran this check and what it turned up.
