Update System Knowledge Map

Perform a codebase archaeology investigation and update docs/SYSTEMKNOWLEDGEMAP.md with current system state.

Investigation Plan

Phase 1: Reconnaissance (Tech Stack)

1. Read package.json for dependencies and scripts
2. Read nuxt.config.ts for framework configuration
3. List app/ directory structure

Phase 2: Data Model Discovery (The Nouns)

1. Read content.config.ts for collection schemas and content types
2. Count items in content/, content/authors/, content/podcasts/
3. Identify any new entity types or schema changes

Phase 3: Capabilities Discovery (The Verbs)

1. List app/pages/ for route handlers
2. List server/api/ for API endpoints
3. Read key pages to understand features
4. List app/composables/ for reusable logic

Phase 4: Business Rules

1. Grep for validation logic in content.config.ts
2. Check for any new business rules in server/api handlers
3. Review any constants or config files

Phase 5: Generate Report

Update docs/SYSTEMKNOWLEDGEMAP.md with:

# System Knowledge Map

> Auto-generated codebase archaeology report for non-technical stakeholders
> Last updated: [current date]

## 1. High-Level Overview

- What this system does (1-2 sentences)
- Tech stack table

## 2. Core Business Entities (The Nouns)

- Content (with all type variants and key attributes)
- Authors
- Podcasts
- Tweets
- Any new entities

## 3. Key Capabilities (The Verbs)

- Content management features
- Discovery & navigation features
- Visualization features
- Reading experience features

## 4. Business Rules & Logic

- Validation rules with file:line references
- Workflows (e.g., reading status)
- Naming conventions

## 5. Integrations

- External services
- Internal modules

## 6. API Surface

- All endpoints with methods and purposes

## 7. File Structure

- Key directories and their purposes

## 8. Current Scale

- Approximate counts of content, authors, etc.

Important Guidelines

• Be thorough: Read actual files, don't assume
• Include counts: Provide real numbers for scale section
• Add line references: For business rules, include file.ts:line
• Update timestamp: Always update the "Last updated" date
• Preserve structure: Keep the same section headings for consistency
