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.

    • Tactic: Credential Access (TA0006)
    • Platforms: Windows
    • Data Sources: Active Directory (Credential Request), Logon Session (Logon Session Metadata)
    • Detection: MITRE DET0157

Kerberos Encryption Types

Etype Value Algorithm Crackable Hashcat Mode
0x17 (23) RC4-HMAC Fast cracking 13100
0x11 (17) AES128-CTS-HMAC-SHA1-96 Slower cracking 19600
0x12 (18) AES256-CTS-HMAC-SHA1-96 Slowest cracking 19700
