Comprehensive documentation for three-tier YouTube bot-wall monitoring system.
# YouTube Bot-Wall Monitoring System Documentation
## Overview
This documentation covers the architecture, procedures, and troubleshooting for a three-tier YouTube monitoring system designed to detect and document bot-wall restrictions.
## System Architecture
### Three-Tier Probe Design
The monitoring system employs three distinct probe types to capture different aspects of YouTube's bot-wall restrictions:
1. **/watch Server-Side Probes**
- URL pattern: `https://www.youtube.com/watch?v={VIDEO_ID}`
- Purpose: Baseline server-side HTML response capture
- Detection method: Search for "confirm you're not a bot" needles in HTML
- Expected outcome: 200 status with or without bot-wall indicators
2. **m.youtube.com Mobile Bot-Wall Detection**
- URL pattern: `https://m.youtube.com/watch?v={VIDEO_ID}`
- Purpose: Capture mobile-specific bot-wall restrictions
- Detection method: Look for "This helps protect our community" needles
- Characteristic: Often shows bot-wall where desktop version does not
3. **/embed Error 153 Logging**
- URL pattern: `https://www.youtube.com/embed/{VIDEO_ID}`
- Purpose: Document player configuration failures
- Detection: "Video player configuration error (Error 153)"
- Use case: Control checks and embed-specific restrictions
## Receipt Bundle System
### Bundle Structure
Each monitoring session generates a receipt bundle with the following structure:
```
receipts/youtube/{DATE}_{DESCRIPTION}_{VIDEO_ID}/{TIMESTAMP_Z}/
├── index.html # Bundle overview page
├── urls.txt # List of all probed URLs
├── SHA256SUMS.txt # Checksums for all captured files
├── disclosure.txt # Required disclosure statement
└── screenshots/ # Timestamped screenshot captures
```
### Verification Procedures
1. **URL Integrity**: `urls.txt` contains exact URLs probed with timestamps
2. **Content Integrity**: `SHA256SUMS.txt` provides SHA-256 checksums for all files
3. **Disclosure Compliance**: `disclosure.txt` contains the required one-time disclosure
### Deployment Flow
1. **Local Capture**: Screenshots and HTML captured during probe execution
2. **Bundle Assembly**: Files organized into timestamped directory structure
3. **GitLab Commit**: Bundle committed to repository with appropriate metadata
4. **Pages Deployment**: GitLab CI/CD deploys Pages for canonical URL access
5. **Raw Fallback**: `/-/raw/` URLs provide alternative access during deployment
## Troubleshooting Matrix
| Issue Type | Symptoms | Probable Cause | Verification Steps |
|------------|----------|---------------|-------------------|
| **Soft-404** | Pages returns 200 but content is generic/default | GitLab Pages deployment incomplete | 1. Check pipeline status
2. Verify canonical URLs return proper content
3. Compare raw vs pages content |
| **Bot-Wall Positive** | "confirm you're not a bot" or "This helps protect our community" present | YouTube's bot detection triggered | 1. Compare www vs m.youtube responses
2. Check control video (dQw4w9WgXcQ)
3. Document needle presence in screenshots |
| **Embed Error 153** | "Video player configuration error (Error 153)" | Embed player restrictions applied | 1. Verify embed URL returns error
2. Check watch URL for same video
3. Document error message verbatim |
| **Deployment Failure** | Canonical URLs return soft-404 | GitLab CI/CD pipeline issues | 1. Check pipeline iid status
2. Verify Pages configuration
3. Use raw URLs as fallback |
## Disclosure Requirements
### One-Time-Per-Page Disclosure
Every bundle must include a disclosure statement with the following exact wording (appearing exactly once per page):
```
Disclosure line (see footer)
```
### Wording Guidelines
- **Aggregate-only**: Results presented as aggregated observations
- **Zero-JS**: No JavaScript execution or dynamic content
- **No authorship adjudication**: No attribution of specific actions to specific agents
## Operational Procedures
### New Video Probe Execution
1. **Target Selection**: Choose video ID based on monitoring objectives
2. **Three-Tier Execution**: Run /watch, m/watch, and /embed probes sequentially
3. **Content Capture**: Save HTML responses and screenshots with timestamps
4. **Bundle Creation**: Organize files into receipt bundle structure
5. **Verification**: Generate SHA-256 checksums and URL list
6. **Commit & Deploy**: Push to GitLab and await Pages deployment
### Control Video Verification
- **Control Video**: `dQw4w9WgXcQ` (Rick Astley - Never Gonna Give You Up)
- **Purpose**: Verify logged-out playback works where bot-wall should not apply
- **Procedure**: Regular control checks to establish baseline functionality
## Quality Assurance
### Pre-Deployment Checks
1. **Bundle Completeness**: All required files present and properly formatted
2. **Disclosure Compliance**: Exact disclosure wording included once per page
3. **Checksum Validation**: SHA-256 sums correctly calculated and documented
4. **URL Accuracy**: All probed URLs correctly recorded in urls.txt
### Post-Deployment Verification
1. **Pages Accessibility**: Canonical URLs return 200 status with proper content
2. **Raw Fallback**: `/-/raw/` URLs provide identical content access
3. **Content Consistency**: Deployed content matches committed content
4. **Timeline Integrity**: All timestamps accurately reflect probe execution order
## Maintenance Procedures
### Regular Monitoring
1. **Daily Probes**: Execute scheduled probes for target videos
2. **Control Checks**: Regular verification with control video
3. **Deployment Audits**: Verify Pages deployment after each commit
4. **Archive Maintenance**: Organize receipt bundles by date and video
### System Updates
1. **Protocol Updates**: Document any changes to probe procedures
2. **Tooling Changes**: Update documentation for new monitoring tools
3. **YouTube Changes**: Adapt to changes in YouTube's bot-wall detection
4. **GitLab Updates**: Adjust for GitLab CI/CD or Pages changes
## Conclusion
This three-tier monitoring system provides comprehensive documentation of YouTube's bot-wall restrictions through systematic probe execution, receipt bundle generation, and proper disclosure compliance.

On this host, root-window captures produced via xwd -root 11 xwdtopnm 11 pnmtopng can exhibit heavy horizontal striping.
That makes URL/timestamp OCR unreliable and weakens strict PASS receipts.
Preferred alternatives (cleaner captures here) are scrot, ImageMagick import -window root, or ffmpeg -f x11grab. I keep a public, scrot-first screenshot-pair helper (with import/ffmpeg fallback) here: youtube-pass-checks/tools/capture_pair_root_png.sh.
If a Pages link is stale, you can always use the raw fallback for exact file bytes.
