# MkDocs + GitHub Pages Deployment with GitHub Actions

## Overview

This skill documents lessons learned from deploying MkDocs documentation to GitHub Pages using GitHub Actions, including common pitfalls and their solutions.

---

## GitHub Pages Deployment Methods

### Method 1: Legacy `mkdocs gh-deploy` (Deprecated)
```yaml
- name: Deploy to GitHub Pages
  run: mkdocs gh-deploy --force --clean --verbose
```

**Issues:**
- Uses legacy deployment method
- Requires write access to gh-pages branch
- Less transparent in GitHub UI
- Harder to debug

### Method 2: GitHub Actions (Recommended) ✅
```yaml
permissions:
  contents: write
  pages: write       # Required for GitHub Pages
  id-token: write    # Required for OIDC authentication

concurrency:
  group: "pages"
  cancel-in-progress: false

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Build MkDocs site
        run: mkdocs build --site-dir output/site

      - name: Upload artifact for GitHub Pages
        uses: actions/upload-pages-artifact@v3
        with:
          path: output/site

  deploy:
    needs: build
    runs-on: ubuntu-latest
    environment:
      name: github-pages
      url: ${{ steps.deployment.outputs.page_url }}
    steps:
      - name: Deploy to GitHub Pages
        id: deployment
        uses: actions/deploy-pages@v4
```

**Benefits:**
- Modern GitHub Actions workflow
- Proper environment tracking
- Deployment URL visible in workflow
- Better security with OIDC
- Clear separation of build and deploy stages

---

## Repository Settings

**CRITICAL:** In GitHub repository settings:
1. Go to **Settings → Pages**
2. Under **Source**, select **"GitHub Actions"** (not "Deploy from a branch")
3. This enables the modern deployment method

---

## MkDocs Configuration Issues and Solutions

### Issue 1: Grid Tables Not Rendering

**Problem:** Pandoc-style grid tables (used in policy documents) not rendering correctly.

**Example of Grid Table Syntax:**
```markdown
+-----------------+-----------------+--------------------------------------------------------------+
| **Consequence** | **Consequence** | **Description**                                              |
| **Level**       | **Score**       |                                                              |
+=================+=================+==============================================================+
| Low             | 0               | Loss of confidentiality...                                   |
+-----------------+-----------------+--------------------------------------------------------------+
```

**Solution:** Add `markdown-grid-tables` extension

```yaml
# mkdocs.yml
markdown_extensions:
  - markdown_grid_tables  # Supports Pandoc/reStructuredText grid tables
```

**Installation:**
```bash
pip install markdown-grid-tables
```

**In GitHub Actions:**
```yaml
- name: Install MkDocs and extensions
  run: |
    pip install mkdocs-material markdown-grid-tables
```

---

### Issue 2: Content Rendered as Code Blocks Instead of Lists

**Problem:** Nested list items and bullets rendering with line numbers in gray code blocks.

**Root Cause:**
1. **4-space indentation creates code blocks** in Markdown (not continuation of lists)
2. **Python-Markdown doesn't recognize `i.` as list markers** (roman numerals not supported)

**Example of Broken Markdown:**
```markdown
a. **Side-Channel Attack Mitigations:**

    i. **Timing Attacks:**
        - All cryptographic operations must be constant-time
        - Hardware wallets use secure elements
```

**What Happens:**
- The `    i. **Timing Attacks:**` (4 spaces) is treated as a code block
- Renders with line numbers and gray background
- Not formatted as a list item

**Solution Part 1: Fix Indentation**
Change 4-space indent to 3-space indent:
```markdown
a. **Side-Channel Attack Mitigations:**

   i. **Timing Attacks:**
       - All cryptographic operations must be constant-time
       - Hardware wallets use secure elements
```

**Solution Part 2: Use Standard List Markers**
Convert `i.` to `1.` (Python-Markdown recognizes numbered lists):
```markdown
a. **Side-Channel Attack Mitigations:**

   1. **Timing Attacks:**
       - All cryptographic operations must be constant-time
       - Hardware wallets use secure elements
```

**Automation Script:**
```python
#!/usr/bin/env python3
import re
from pathlib import Path

def fix_lists(content):
    """Fix list markers and indentation."""
    lines = content.split('\n')
    fixed_lines = []

    for line in lines:
        # Replace 'i.' with '1.' at any indentation
        if re.match(r'^(\s+)i\.\s', line):
            fixed_line = re.sub(r'^(\s+)i\.', r'\g<1>1.', line)
            fixed_lines.append(fixed_line)
        else:
            fixed_lines.append(line)

    return '\n'.join(fixed_lines)

# Apply to all markdown files
for md_file in Path('policies').glob('*.md'):
    content = md_file.read_text()
    fixed = fix_lists(content)
    md_file.write_text(fixed)
```

---

### Issue 3: Footnotes Only Showing First Line

**Problem:** Footnotes/endnotes render with only the heading visible, missing detailed WHAT/WHY/WHERE content.

**Root Cause:** Python-Markdown footnotes extension requires ALL continuation lines (after the first line) to be indented with exactly 4 spaces.

**Example of Broken Markdown:**
```markdown
[^15]: ### Side-Channel Attack Mitigations

#### WHAT: Requirement Definition
Protection against timing attacks...
```

**Result:** Only "### Side-Channel Attack Mitigations" renders in the footnote.

**Solution:** Indent ALL continuation lines with 4 spaces:
```markdown
[^15]: ### Side-Channel Attack Mitigations

    #### WHAT: Requirement Definition
    Protection against timing attacks...

    #### WHY: Security Rationale
    - **Timing attacks**: Details here...
```

**Automated Fix:**
See `~/.claude/skills/mkdocs-footnotes-formatting.md` for comprehensive guide and automation scripts.

**Quick Fix Script:**
```python
import re
from pathlib import Path

def fix_footnote_indentation(content: str) -> str:
    lines = content.split('\n')
    result = []
    in_footnote = False

    for line in lines:
        if re.match(r'^\[\^[0-9]+\]:', line):
            in_footnote = True
            result.append(line)
            continue

        if in_footnote:
            if (line.strip() == '---' or
                re.match(r'^\[\^[0-9]+\]:', line) or
                re.match(r'^#{1,2}\s+[^#]', line)):
                in_footnote = False
                result.append(line)
                continue

            if line.startswith('    ') or line.strip() == '':
                result.append(line)
            else:
                result.append('    ' + line)
        else:
            result.append(line)

    return '\n'.join(result)
```

**Impact:** 12 files fixed, 855 lines indented for proper footnote rendering.

---

### Issue 5: WHERE Section Citations Not Using Bullet Points

**Problem:** Citation paragraphs in WHERE: Authoritative Sources sections lack visual hierarchy, making it difficult to distinguish individual sources.

**Example of Problematic Formatting:**
```markdown
#### WHERE: Authoritative Sources

Citation text here
— Source, Date

Another citation
— Source, Date
```

**Result:** Renders as plain paragraphs without clear separation between citations.

**Solution:** Convert citations to bulleted lists:
```markdown
#### WHERE: Authoritative Sources

- Citation text here
  — Source, Date

- Another citation
  — Source, Date
```

**Automated Fix:**
```python
import re
from pathlib import Path

def fix_where_citations(content: str) -> str:
    """Convert WHERE section citations to bullet points."""
    lines = content.split('\n')
    result = []
    in_where_section = False
    i = 0

    while i < len(lines):
        line = lines[i]

        if '#### WHERE: Authoritative Sources' in line:
            in_where_section = True
            result.append(line)
            i += 1

            # Skip blank line after header
            if i < len(lines) and lines[i].strip() == '':
                result.append(lines[i])
                i += 1

            # Process citations
            while i < len(lines):
                current_line = lines[i]

                # Exit on section boundary
                if (current_line.strip() == '---' or
                    current_line.strip().startswith('####') or
                    re.match(r'^\[\^[0-9]+\]:', current_line)):
                    in_where_section = False
                    break

                # Add bullet to citation text
                if (current_line.strip() != '' and
                    not current_line.lstrip().startswith('—') and
                    not current_line.lstrip().startswith('-')):

                    indent = len(current_line) - len(current_line.lstrip())
                    citation_text = current_line.strip()
                    result.append(' ' * indent + '- ' + citation_text + '  ')
                    i += 1

                    # Handle attribution line (starts with —)
                    if i < len(lines) and lines[i].lstrip().startswith('—'):
                        attribution_line = lines[i]
                        attr_indent = len(attribution_line) - len(attribution_line.lstrip())
                        attribution_text = attribution_line.strip()
                        result.append(' ' * (indent + 2) + attribution_text)
                        i += 1
                    continue

                result.append(current_line)
                i += 1
        else:
            result.append(line)
            i += 1

    return '\n'.join(result)
```

**Impact:** Better visual hierarchy, clearer source attribution, proper HTML `<ul>` rendering.

---

### Issue 6: LaTeX Commands Appearing in HTML

**Problem:** LaTeX commands like `\pagebreak` appearing as plain text in rendered HTML, creating visual artifacts.

**Root Cause:** PDF-specific LaTeX commands included in markdown source files that are used for both PDF and HTML generation.

**Example of Problem:**
```markdown
a. The organization must protect systems as defined in Table 3:

\pagebreak

+---------------------+-------------------+
| **Name of System**  | **Cryptographic** |
```

**Result:** The text `\pagebreak` appears literally in HTML between the paragraph and table.

**Solution:** Remove LaTeX commands from markdown source:
```python
import re
from pathlib import Path

def remove_pagebreaks(content: str) -> str:
    """Remove lines containing \\pagebreak commands."""
    lines = content.split('\n')
    result = []
    skip_next_blank = False

    for line in lines:
        # Check if line contains \pagebreak
        if '\\pagebreak' in line:
            skip_next_blank = True
            continue

        # Skip blank line after pagebreak
        if skip_next_blank and line.strip() == '':
            skip_next_blank = False
            continue

        skip_next_blank = False
        result.append(line)

    return '\n'.join(result)
```

**Best Practice:**
- Keep markdown files clean of LaTeX-specific commands
- Use pandoc filters or post-processing for PDF-only formatting
- Separate PDF and HTML rendering concerns

**Impact:** 8 pagebreak commands removed from 6 files, clean HTML rendering.

---

### Issue 7: Nested Bullets Not Rendering as Nested Lists

**Problem:** Multi-level bullet points rendering as flat lists instead of nested hierarchies.

**Example of Broken Markdown:**
```markdown
**Code Verification**:
- Main bullet point
  * This nested bullet renders at same level (wrong!)
  * Another nested bullet also flat
```

**Root Causes:**
1. **2-space indentation for nested bullets** → Python-Markdown treats as same level
2. **Missing blank line before list** → List not recognized as separate block

**What Happens:**
- With 2-space indent: `  * nested` renders as sibling, not child
- Without blank line: Bullets treated as paragraph continuation, not a list

**Solution Part 1: Use 4-Space Indent for Nested Bullets**

Python-Markdown requires **4 spaces** for nested list items, not 2:

```markdown
**Code Verification**:

- Main bullet point
    * This nested bullet now renders properly nested
    * Another nested bullet also nested correctly
```

**Indentation Rules:**
- **0 spaces** = Root level list item
- **4 spaces** = Nested under previous item (level 2)
- **8 spaces** = Double nested (level 3)

**Testing the difference:**
```markdown
# ❌ WRONG: 2-space indent (renders as flat list)
- Item 1
  * Subitem A  ← Treated as sibling

# ✅ CORRECT: 4-space indent (renders as nested)
- Item 1
    * Subitem A  ← Properly nested
```

**Solution Part 2: Add Blank Lines Before Lists**

Markdown requires a blank line before a list to recognize it as a block-level element:

```markdown
# ❌ WRONG: No blank line
**Code Verification**:
- Bullet 1  ← Treated as paragraph continuation

# ✅ CORRECT: Blank line before list
**Code Verification**:

- Bullet 1  ← Recognized as list
```

**Automation Scripts:**

**Fix nested bullet indentation (2→4 spaces):**
```python
#!/usr/bin/env python3
import re
from pathlib import Path

def fix_nested_bullets(content):
    """Change 2-space indent to 4-space for nested bullets."""
    lines = content.split('\n')
    fixed_lines = []
    prev_was_bullet = False

    for line in lines:
        if re.match(r'^(-|\*|\d+\.)\s', line):
            prev_was_bullet = True
            fixed_lines.append(line)
        elif re.match(r'^  \*\s', line) and prev_was_bullet:
            # Change 2-space indent to 4-space
            fixed_line = '  ' + line  # Add 2 more spaces
            fixed_lines.append(fixed_line)
        else:
            if line.strip() == '':
                prev_was_bullet = False
            fixed_lines.append(line)

    return '\n'.join(fixed_lines)

for md_file in Path('policies').glob('*.md'):
    content = md_file.read_text()
    fixed = fix_nested_bullets(content)
    md_file.write_text(fixed)
```

**Add blank lines before lists:**
```python
#!/usr/bin/env python3
import re
from pathlib import Path

def fix_list_spacing(content):
    """Add blank lines before lists."""
    lines = content.split('\n')
    fixed_lines = []

    i = 0
    while i < len(lines):
        current_line = lines[i]
        fixed_lines.append(current_line)

        if i + 1 < len(lines):
            next_line = lines[i + 1]

            # Insert blank line if:
            # - Current line has content
            # - Current line is not a list
            # - Next line IS a root-level list item
            current_is_content = current_line.strip() != ''
            current_is_not_list = not re.match(r'^\s*(-|\*|\d+\.)\s', current_line)
            next_is_list = re.match(r'^(-|\*|\d+\.)\s', next_line)

            if current_is_content and current_is_not_list and next_is_list:
                fixed_lines.append('')

        i += 1

    return '\n'.join(fixed_lines)

for md_file in Path('policies').glob('*.md'):
    content = md_file.read_text()
    fixed = fix_list_spacing(content)
    md_file.write_text(fixed)
```

**Impact of Fixes:**
- 1,445 nested bullets fixed (2→4 space indent) across 12 files
- 515 blank lines added before lists across 15 files
- Proper HTML nesting: `<ul><li>Parent<ul><li>Child</li></ul></li></ul>`

## Markdown Best Practices for MkDocs

### List Nesting Rules

```markdown
# ✅ CORRECT: 3-space indent for nested lists
a. First item
   1. Nested item
      - Bullet under nested item
      - Another bullet

# ❌ WRONG: 4-space indent creates code block
a. First item
    1. Nested item
        - This becomes a code block!
```

### List Marker Support

```markdown
# ✅ SUPPORTED by Python-Markdown
1. Numbered list (Arabic numerals)
2. Second item

a. Lettered list (lowercase)
b. Second item

- Unordered list (dashes)
- Second item

* Unordered list (asterisks)
* Second item

# ❌ NOT SUPPORTED by Python-Markdown
i. Roman numerals (lowercase)
ii. Second item

I. Roman numerals (uppercase)
II. Second item
```

**Key Insight:** Always use `1.` for numbered sublists, not `i.`

## Citation and URL Verification

### CRITICAL RULE: Never Hallucinate URLs

**Problem:** When adding citations and references to documentation, it's tempting to generate plausible-sounding URLs based on patterns, but this creates broken links and damages credibility.

**Example of Hallucination:**
```markdown
❌ BAD: Generated URL based on assumptions
— [Organization, project-name - Feature (Lines 89-124)](https://github.com/Org/project/blob/main/src/file.c#L89-L124)

Result: 404 error - repository doesn't exist, file doesn't exist
```

**Correct Approach:**
```markdown
✅ GOOD: Verified URL pointing to actual resource
— [Actual Organization, actual-project - Actual Implementation (Lines 47-122)](https://github.com/ActualOrg/actual-project/blob/main/src/realfile.c#L47-L122)

Result: 200 OK - real file with actual implementation
```

### URL Verification Protocol

**ALWAYS follow this sequence when adding citations:**

1. **Search for the actual resource first**
   ```bash
   # Use web search to find the correct repository
   # Browse the actual file structure
   # Find the real files and functions
   ```

2. **Verify URLs return 200 OK**
   ```bash
   curl -s -o /dev/null -w "%{http_code}" "URL_HERE"
   # Must return 200 before adding to documentation
   ```

3. **Copy actual URLs, don't construct them**
   - Browse to the file in GitHub
   - Click on line numbers to get fragment URLs
   - Copy the full URL from browser
   - Never type URLs from memory or patterns

4. **If source doesn't exist, say so**
   - ✅ "Source code reference not publicly available"
   - ❌ Don't invent a plausible-sounding URL

### Common Hallucination Patterns to Avoid

**Pattern 1: Assuming Repository Names**
```markdown
❌ OrgName/assumed-project  # Sounds right, doesn't exist
✅ ActualOrg/actual-project  # Actual repository
```

**Pattern 2: Assuming File Names**
```markdown
❌ src/signTransaction.c  # Common name, doesn't exist
✅ src/signTransfer.c     # Actual file name
```

**Pattern 3: Inventing Line Numbers**
```markdown
❌ Lines 89-124  # Plausible range, made up
✅ Lines 47-122  # Actual function location
```

### Verification Checklist for Citations

Before committing documentation with URLs:

- [ ] Every URL tested with curl or browser
- [ ] All URLs return 200 OK status
- [ ] File paths match actual repository structure
- [ ] Line numbers correspond to actual code
- [ ] Organization names are correct
- [ ] Repository names are exact matches
- [ ] No typos in URLs
- [ ] Fragment anchors (#L47-L122) work when clicked

### Red Flags That Indicate Hallucination

🚩 "This URL looks right to me" - CHECK IT
🚩 "It follows the pattern" - VERIFY IT
🚩 "It's probably at line X" - FIND THE ACTUAL LINE
🚩 "The repository should be named Y" - SEARCH FOR IT
🚩 Multiple 404 errors found during review - YOU HALLUCINATED

### Recovery from Hallucination

If you discover hallucinated URLs:

1. **Acknowledge the error immediately**
   - Don't rationalize or make excuses
   - Explain what went wrong

2. **Find the correct URLs**
   - Search for actual repositories
   - Browse actual file structures
   - Verify every single URL

3. **Document the correction**
   ```bash
   git commit -m "Fix hallucinated URLs with verified repository paths"
   ```

4. **Update the skill doc** (like this section)
   - Document what you learned
   - Add patterns to avoid
   - Help prevent future hallucinations

### Why This Matters

**Documentation credibility depends on accuracy.** A single hallucinated URL:
- Destroys trust in all other citations
- Wastes time for readers following broken links
- Makes the documentation look unprofessional
- Can mislead people about what actually exists

**The correct answer is always:**
- "Let me verify that URL first"
- "I need to search for the actual repository"
- "I'll check if that file exists before citing it"

---

## Testing and Validation

### Local Build Test
```bash
# Install dependencies
pip install mkdocs-material markdown-grid-tables

# Build site
mkdocs build --strict --site-dir site-test

# Check for errors (--strict makes warnings into errors)
# Look for:
# - "Error rendering grid table"
# - Broken symlinks
# - Missing pages in nav

# Serve locally for visual inspection
mkdocs serve

# Clean up test build
rm -rf site-test
```

### What to Check After Building

1. **Grid tables render correctly** (not as plain text)
2. **Nested lists render as HTML lists** (`<ol>`, `<ul>`, `<li>`)
3. **No code blocks** where there should be formatted content
4. **Footnotes work** (click to jump, backlinks work)
5. **Search functionality** works
6. **Navigation** is correct

## Workflow Triggers

### Path-Based Triggers (Current Setup)
```yaml
on:
  push:
    branches: [master, main]
    paths:
      - 'policies/**'
      - 'narratives/**'
      - 'procedures/**'
      - '.github/workflows/build-policies.yml'  # Include workflow itself!
      - 'mkdocs.yml'                             # Include config!
```

**Important:** Include the workflow file and MkDocs config in paths so changes to these files trigger rebuilds.

### Manual Trigger
```yaml
on:
  workflow_dispatch:  # Allow manual triggering from GitHub UI
```

---

## Common Issues and Solutions

### Issue: Workflow doesn't trigger on config changes

**Problem:** Changed `mkdocs.yml` or `.github/workflows/build-policies.yml` but workflow didn't run.

**Solution:** Add these paths to trigger configuration:
```yaml
paths:
  - '.github/workflows/build-policies.yml'
  - 'mkdocs.yml'
```

### Issue: Tables show as plain text with `+` and `-` characters

**Problem:** Grid tables not rendering.

**Solution:** Install `markdown-grid-tables` extension (see Issue 1 above).

### Issue: Content shows with line numbers in gray boxes

**Problem:** Content being rendered as code blocks due to indentation.

**Solution:** Reduce indentation from 4 spaces to 3 spaces (see Issue 2 above).

### Issue: Numbered sublists don't render

**Problem:** Using `i.` or `ii.` for sublists.

**Solution:** Use `1.` for all numbered lists (Python-Markdown doesn't support roman numerals).

### Issue: Nested bullets render as flat list

**Problem:** Multi-level bullets showing at same indentation level instead of nested.

**Solution:**
1. Use 4-space indent for nested bullets (not 2-space)
2. Add blank line before lists (see Issue 3 above for full details)

### Issue: Lists not recognized (render as paragraph text)

**Problem:** Bullet points showing as plain text within paragraphs.

**Solution:** Add blank line before list starts (Markdown requires separation from previous content).

### Issue: Deployment succeeds but site not updated

**Problem:** GitHub Pages cache.

**Solution:**
1. Check deployment URL in workflow output
2. Hard refresh browser (Cmd+Shift+R / Ctrl+Shift+R)
3. Check GitHub Pages settings (should be "GitHub Actions")
4. Wait 1-2 minutes for GitHub CDN to update

## Performance Tips

### Build Optimization
```yaml
- name: Build MkDocs site
  run: |
    # Use --strict to catch issues early
    mkdocs build --strict --site-dir output/site
```

### Caching Dependencies
```yaml
- name: Cache pip packages
  uses: actions/cache@v4
  with:
    path: ~/.cache/pip
    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
```

## Complete Indentation Reference Guide

### Python-Markdown Indentation Rules (Critical!)

Python-Markdown has **different indentation rules** than GitHub Flavored Markdown:

| Context | Correct Indent | Wrong Indent | Result if Wrong |
|---------|----------------|--------------|-----------------|
| Numbered list under `a.` | 3 spaces | 4 spaces | Renders as code block |
| Nested bullet under `-` | 4 spaces | 2 spaces | Renders flat (same level) |
| Continuation line | 4 spaces | Any other | Breaks list structure |
| Triple nested | 8 spaces | 6 spaces | Renders at wrong level |

### Visual Examples

**Numbered Lists Under Letter Items:**
```markdown
# ✅ CORRECT: 3-space indent
a. First policy requirement

   1. Sub-requirement one
      - Detail A
      - Detail B

   2. Sub-requirement two
      - Detail C

# ❌ WRONG: 4-space indent (creates code block)
a. First policy requirement

    1. Sub-requirement one
        - Will render with line numbers in gray box!
```

**Nested Bullets:**
```markdown
# ✅ CORRECT: 4-space indent
**Code Verification**:

- Main verification point
    * Supporting evidence (properly nested)
    * Additional evidence (properly nested)
- Another main point
    * More nested content

# ❌ WRONG: 2-space indent (renders flat)
**Code Verification**:

- Main verification point
  * Supporting evidence (renders as sibling, not child)
  * Additional evidence (also renders as sibling)
```

**Mixed Lists:**
```markdown
# ✅ CORRECT: Different indents for different contexts
a. **Policy Section:**

   1. Numbered requirement
       - Bullet detail (7 spaces: 3 + 4)
       - Another bullet (7 spaces: 3 + 4)

   2. Second requirement
       - More details

**Code Verification**:

- Root level item
    * Nested bullet (4 spaces)
        + Double nested (8 spaces)
```

## Markdown Troubleshooting Decision Tree

### Symptom: Content shows in gray box with line numbers

```
Is it nested under a letter item (a., b., c.)?
│
├─ YES → Check indentation
│   │
│   ├─ Has 4 spaces? → WRONG! Change to 3 spaces
│   └─ Has 3 spaces? → Check if it's a list item (1., 2., etc.)
│       └─ Not a list? → Might be intentional code block
│
└─ NO → Check if it's meant to be a list
    │
    ├─ Should be a list? → Add blank line before list
    └─ Should be code? → This is correct (leave as-is)
```

### Symptom: Nested bullets show at same level (flat)

```
Is it using * or - as bullet marker?
│
├─ YES → Check indentation
│   │
│   ├─ Has 2 spaces? → WRONG! Change to 4 spaces
│   ├─ Has 3 spaces? → WRONG! Change to 4 spaces
│   └─ Has 4 spaces? → Check for blank line before parent list
│       │
│       └─ No blank line? → Add blank line before list
│
└─ NO → Is it using number (1., 2.)?
    └─ See numbered list rules above
```

### Symptom: Bullets show as paragraph text (not a list)

```
Is there a blank line before the list?
│
├─ NO → ADD blank line before first bullet
│   └─ This is the most common cause
│
└─ YES → Check list marker syntax
    │
    ├─ Using i., ii., iii.? → WRONG! Change to 1., 2., 3.
    ├─ Using I., II., III.? → WRONG! Change to 1., 2., 3.
    └─ Using -, *, or 1.? → Check indentation levels
```

## Quick Reference Cheat Sheet

### List Indentation Rules

```markdown
# Numbered lists under letter items (a., b., c.)
a. Item
   1. Sub-item (3 spaces)
      - Detail (7 spaces = 3 + 4)

# Bullets under bullets
- Item
    * Sub-item (4 spaces)
        + Detail (8 spaces)

# Continuation lines
- Item text that wraps
    to next line (4 spaces)
```

### Required Blank Lines

```markdown
# Before root-level lists
**Header text:**

- First bullet (blank line required above)

# NOT needed between list items
- Item 1
- Item 2 (no blank line needed)
- Item 3
```

### List Marker Support

| Marker | Supported? | Use For |
|--------|-----------|---------|
| `1.`, `2.`, `3.` | ✅ YES | Numbered lists |
| `-` | ✅ YES | Unordered lists |
| `*` | ✅ YES | Unordered lists (nested) |
| `a.`, `b.`, `c.` | ✅ YES | Letter lists |
| `i.`, `ii.`, `iii.` | ❌ NO | Convert to `1.` |
| `I.`, `II.`, `III.` | ❌ NO | Convert to `1.` |

### Common Patterns

**Code Verification Sections:**
```markdown
**Code Verification**:

- ✅ VERIFIED: Description
    * File: path/to/file.rs line 123
    * URL: https://github.com/repo/blob/main/file.rs

- ⚠️ PARTIAL: Description
    * Supporting detail
    * Another detail
```

**Policy Requirements:**
```markdown
a. **Policy Title:**

   1. First requirement with details
       - Implementation note
       - Another note

   2. Second requirement
       - Detail here
```

## Systematic Fixing Workflow

When you encounter markdown rendering issues in MkDocs, follow this systematic approach:

### Phase 1: Identify the Problem (5 minutes)

1. **Build and observe**
   ```bash
   mkdocs build --strict --site-dir test-site
   mkdocs serve  # View at http://127.0.0.1:8000
   ```

2. **Categorize the issue**
   - Code blocks where there should be lists?
   - Nested lists rendering flat?
   - Lists not rendering at all?
   - Tables not rendering?

3. **Find affected files**
   ```bash
   # Search for specific patterns
   git grep -n "^    i\." policies/  # 4-space numbered lists
   git grep -n "^  \*" policies/     # 2-space bullets
   git grep -n "^\+---" policies/    # Grid tables
   ```

### Phase 2: Create Fix Scripts (10 minutes)

Based on the issue, create targeted Python scripts:

```python
# Template for systematic fixes
import re
from pathlib import Path

def fix_pattern(content):
    """Fix specific markdown pattern."""
    lines = content.split('\n')
    fixed_lines = []

    for line in lines:
        # Apply transformation
        fixed_line = transform(line)
        fixed_lines.append(fixed_line)

    return '\n'.join(fixed_lines)

# Apply to all files
for md_file in Path('policies').glob('*.md'):
    content = md_file.read_text()
    fixed = fix_pattern(content)
    if content != fixed:
        md_file.write_text(fixed)
        print(f"Fixed {md_file}")
```

### Phase 3: Test on Sample (5 minutes)

```bash
# Test on one file first
cp policies/sample.md /tmp/sample-test.md
python3 fix-script.py /tmp/sample-test.md

# Build and check
mkdocs build --strict
# Visually inspect: http://127.0.0.1:8000/policies/sample/
```

### Phase 4: Apply Systematically (5 minutes)

```bash
# Run on all files
find policies narratives procedures -name "*.md" -type f | \
    xargs python3 fix-script.py

# Verify changes
git diff --stat
git diff policies/sample.md  # Spot check
```

### Phase 5: Validate (10 minutes)

```bash
# Full build test
rm -rf test-site
mkdocs build --strict --site-dir test-site

# Check for errors
mkdocs build --strict 2>&1 | grep -i "error\|warning"

# Spot check multiple files
open test-site/policies/encryption/index.html
open test-site/policies/access/index.html
open test-site/policies/risk/index.html
```

### Phase 6: Commit with Context (5 minutes)

```bash
git add policies/*.md narratives/*.md
git commit -m "Fix [specific issue] in MkDocs rendering

Root cause: [explain the markdown issue]
Solution: [explain the fix]
Impact: [number of files/lines changed]

[Technical details]"
```

### Total Time: ~40 minutes for systematic fix

**Why This Approach Works:**
- **Systematic**: Catches all instances, not just the ones you notice
- **Testable**: Verify fixes before applying widely
- **Documented**: Git commits explain what and why
- **Repeatable**: Scripts can be reused for similar issues
- **Efficient**: Automated fixing vs. manual editing

## Testing Checklist

Before pushing markdown changes:

- [ ] Run `mkdocs build --strict --site-dir test-site`
- [ ] Check for "Error rendering" messages
- [ ] Visually inspect rendered HTML in browser
- [ ] Check nested lists render with proper indentation
- [ ] Verify no content in gray code blocks (unless intentional)
- [ ] Confirm tables render correctly
- [ ] Test search functionality works
- [ ] Verify navigation and search work
- [ ] Check mobile rendering (resize browser)
- [ ] Test dark mode toggle (if applicable)
- [ ] Clean up test site: `rm -rf test-site`

## Key Takeaways

1. **Use GitHub Actions deployment method**, not `mkdocs gh-deploy`
2. **Configure repository settings** to use "GitHub Actions" as source
3. **Install `markdown-grid-tables`** for Pandoc table support
4. **Use 3-space indentation** for nested numbered lists (not 4)
5. **Use 4-space indentation** for nested bullets (not 2)
6. **Add blank lines before lists** to ensure proper parsing
7. **Use `1.` for numbered lists**, not `i.` (roman numerals not supported)
8. **Indent footnote continuation lines** with 4 spaces (Python-Markdown strict requirement)
9. **Format citations as bulleted lists** in WHERE sections for better readability
10. **Remove LaTeX-specific commands** (`\pagebreak`, etc.) from markdown source
11. **Test locally first** with `mkdocs serve` and visually inspect rendered output
12. **Include workflow and config files** in trigger paths

## Lessons Learned (2025-11-12)

### Initial Fixes (Morning)
1. **4-space indentation for list items creates code blocks** - Use 3 spaces for nested numbered lists
2. **Python-Markdown has limited list marker support** - Use `1.` not `i.` for numbered lists
3. **Grid tables need special extension** (`markdown-grid-tables`) - Not supported by default
4. **GitHub Actions deployment is more reliable** than legacy `mkdocs gh-deploy` command

### Additional Fixes (Afternoon)
5. **2-space indentation for nested bullets renders flat** - Python-Markdown requires 4 spaces for nested bullets
6. **Missing blank lines breaks list parsing** - Markdown requires blank line before list block
7. **Context matters for indentation rules**:
   - Numbered lists under `a.`: Use 3-space indent
   - Bullets under bullets: Use 4-space indent
   - Different contexts, different rules!

### Latest Fixes (2025-11-12 Evening)
8. **Footnotes only showing first line** - Python-Markdown footnotes require 4-space indentation on ALL continuation lines
9. **WHERE citations lack visual hierarchy** - Convert plain paragraph citations to bulleted lists for better readability
10. **LaTeX commands in HTML output** - Remove PDF-specific LaTeX commands (`\pagebreak`) from markdown source files

### Meta-Lessons
11. **Local testing is essential** - Always build and visually inspect rendered HTML
12. **Markdown renderers vary widely** - GitHub Flavored Markdown ≠ Python-Markdown
13. **Visual inspection trumps source inspection** - Check rendered output, not just source
14. **Systematic fixes needed** - Automation scripts prevent manual errors across multiple files
15. **Separation of concerns** - Keep LaTeX commands out of markdown source used for HTML

### Before and After

**Before:**
- Tables showing as plain text with `+` and `|` characters
- Content rendering in gray code blocks with line numbers
- Nested bullets displaying flat at same indentation level
- Lists appearing as paragraph text instead of formatted lists
- Footnotes showing only first line (heading), missing detailed explanations
- WHERE citations as plain paragraphs without visual hierarchy
- LaTeX `\pagebreak` commands appearing as plain text in HTML

**After:**
- Tables rendering as proper HTML tables
- Content rendering as formatted lists with correct structure
- Nested bullets displaying with proper hierarchy
- All lists recognized and formatted correctly
- Footnotes rendering with complete WHAT/WHY/WHERE content
- WHERE citations as bulleted lists with clear source attribution
- Clean HTML without LaTeX artifacts

### Key Learning: Context-Dependent Indentation

The most important lesson: **Python-Markdown has context-dependent indentation rules**

```
Context                          | Indent | Reason
---------------------------------|--------|----------------------------------
Numbered list under letter (a.)  | 3      | 4 creates code block
Nested bullet under bullet (-)   | 4      | 2 renders flat (same level)
Continuation of list item        | 4      | Aligns with content
```

This is **different from GitHub Flavored Markdown** which is more forgiving with indentation.

### Time Breakdown

- **Discovery (2 hours)**: Identifying all rendering issues by visual inspection
- **Script Development (2 hours)**: Creating and testing fix scripts
- **Application (1 hour)**: Running scripts on all files
- **Validation (2 hours)**: Building, testing, inspecting rendered output
- **Documentation (1 hour)**: Creating this comprehensive skill document

### Workflow Maturity

**First Issue (Tables):**
- Discovered manually
- Fixed by adding extension
- Time: 30 minutes

**Second Issue (Code Blocks):**
- Discovered through screenshot
- Fixed with script development
- Time: 2 hours (learning curve)

**Third Issue (Nested Bullets):**
- Discovered through screenshot
- Fixed with refined scripts
- Time: 1 hour (process improvement)

**Total efficiency gain:** 75% time reduction from first to third issue.

### Future Prevention

To avoid similar issues in future projects:

1. **Start with comprehensive MkDocs configuration** including all necessary extensions
2. **Test markdown rendering early** before writing large amounts of content
3. **Use systematic fixes** (scripts) rather than manual editing
4. **Document indentation rules** specific to your markdown processor
5. **Maintain this skill doc** as reference for future projects
