Consolidate 22 sibling repos into layered organism structure
Place useful parts of the surrounding repos into sica-fondt by layer, per the
body model (Ada = membrane; brain/endocrine/capabilities/knowledge non-Ada):

- brain/        LLM reasoning + providers (dapr, hermes, MoMoA)
- capabilities/ REPRAG sidecars: hermes tools/skills, dapr tools, parallel
                dispatch, A51 channels, and the OSINT cluster
- knowledge/    LORAG corpus: 754 cyber-skills, agency personas, secure-coding,
                MITRE ATT&CK data
- reference/    defensive threat-reference (C3, shhbruh doc) + AdaYaml parser

License handling: AGPL sources (worldosint, advanced_evolution, mercury,
Reticulum) and GPL DeTTECT are SPEC-only clean-room/port descriptions — no
copyleft code copied. MIT/Apache/data parts copied as working trees.

Safety: shhbruh escape/persistence material and C3 covert-C2 kept as reference
only, not wired into the running organism. See CONSOLIDATION.md.

# API Reference: Broken Link Hijacking
## Concept
Broken Link Hijacking (BLH) occurs when a website links to external resources
that no longer exist. An attacker can register the expired resource (domain,
GitHub repo, npm package) to serve malicious content via the trusted site.
## Hijackable Platforms
| Platform | Hijack Vector |
|----------|---------------|
| GitHub | Register abandoned username/repo |
| npm | Publish unclaimed package name |
| PyPI | Register unclaimed package |
| Twitter/X | Claim abandoned handle |
| BitBucket | Register abandoned team/repo |
| Custom domain | Register expired domain |
## Python requests — Link Checking
### HEAD Request
```python
import requests
resp = requests.head(url, timeout=10, allow_redirects=True, verify=False)
# 404 = broken link, potential hijack
```
### Connection Error = Domain Takeover
```python
try:
requests.head(url, timeout=5)
except requests.ConnectionError:
print("Domain may be unregistered - takeover possible")
```
## HTML Link Extraction
### Regex Patterns
```python
import re
# href links
re.finditer(r'href=["\']([^"\']+)', html)
# src links
re.finditer(r'src=["\']([^"\']+)', html)
```
## Domain Availability Check
### WHOIS Lookup
```bash
whois expired-domain.com
# "No match for" = available for registration
```
### DNS Check
```bash
dig expired-domain.com +short
# Empty = no DNS records (likely available)
```
## GitHub API — Check Username Availability
### Check user exists
```http
GET https://api.github.com/users/username
```
- 200 = exists
- 404 = available for registration
### Check repo exists
```http
GET https://api.github.com/repos/owner/repo
```
## npm Registry — Check Package
```http
GET https://registry.npmjs.org/package-name
```
- 200 = exists
- 404 = available for registration
## Subdomain Takeover Indicators
### CNAME to Unclaimed Service
```bash
dig CNAME old-service.example.com
# old-service.example.com. CNAME unregistered.herokuapp.com.
```
### Common Vulnerable Services
| Service | Indicator |
|---------|-----------|
| GitHub Pages | 404 "There isn't a GitHub Pages site here" |
| Heroku | "No such app" |
| AWS S3 | "NoSuchBucket" |
| Azure | "404 Web Site not found" |
| Shopify | "Sorry, this shop is currently unavailable" |
