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: Implementing DMARC/DKIM/SPF Email Security
## dnspython Lookups
```python
import dns.resolver
# SPF
answers = dns.resolver.resolve("example.com", "TXT")
# DMARC
answers = dns.resolver.resolve("_dmarc.example.com", "TXT")
# DKIM
answers = dns.resolver.resolve("selector._domainkey.example.com", "TXT")
```
## SPF Record Syntax
| Mechanism | Example | Meaning |
|-----------|---------|---------|
| `include:` | `include:_spf.google.com` | Authorize sender |
| `ip4:` | `ip4:203.0.113.0/24` | Allow IP range |
| `-all` | End of record | Hard fail others |
| `~all` | End of record | Soft fail (weak) |
| `+all` | End of record | Allow all (insecure) |
## DMARC Policy Levels
| Policy | Action | Severity if Missing |
|--------|--------|---------------------|
| `p=reject` | Reject failing mail | Recommended |
| `p=quarantine` | Send to spam | Acceptable |
| `p=none` | Monitor only | HIGH risk |
## Recommended DNS Records
```
# SPF
v=spf1 include:_spf.google.com -all
# DMARC
v=DMARC1; p=reject; pct=100; rua=mailto:dmarc@example.com; adkim=s; aspf=s
# DKIM (provider-specific key)
selector._domainkey.example.com TXT "v=DKIM1; k=rsa; p=MIIBIjAN..."
```
