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.

Field Type Description
ts time Timestamp of the DNS request
uid string Unique connection identifier
id.orig_h addr Source IP address
id.orig_p port Source port
id.resp_h addr Destination IP (DNS server)
id.resp_p port Destination port (usually 53)
proto enum Transport protocol (udp/tcp)
trans_id count DNS transaction ID
rtt interval Round trip time
query string The domain name queried
qclass count Query class value
qclass_name string Query class name (C_INTERNET)
qtype count Query type value
qtype_name string Query type name (A, AAAA, TXT, MX, CNAME, NULL)
rcode count Response code value
rcode_name string Response code name (NOERROR, NXDOMAIN, SERVFAIL)
AA bool Authoritative Answer flag
TC bool Truncation flag
RD bool Recursion Desired flag
RA bool Recursion Available flag
Z count Reserved field
answers vector Resource record answers
TTLs vector TTL values for answer RRs
rejected bool Whether query was rejected

zeek-cut Usage

# Extract specific fields from dns.log
cat dns.log | zeek-cut ts id.orig_h query qtype_name answers

# Filter TXT queries (common in DNS tunneling)
cat dns.log | zeek-cut query qtype_name | grep TXT

# Count queries per domain
cat dns.log | zeek-cut query | rev | cut -d. -f1-2 | rev | sort | uniq -c | sort -rn

Suricata DNS Exfiltration Rules

# Detect long DNS queries (potential tunneling)
alert dns any any -> any any (msg:"Possible DNS tunneling - long query"; \
  dns.query; content:"|00|"; byte_test:1,>,50,0,relative; \
  sid:1000001; rev:1;)

# Detect TXT record queries to unusual domains
alert dns any any -> any any (msg:"Suspicious DNS TXT query"; \
  dns_query; pcre:"/^[a-z0-9]{30,}\./i"; sid:1000002; rev:1;)
