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: Detecting Ransomware Encryption Behavior

Shannon Entropy

Formula: H(X) = -Sum p(x) log2(p(x)). For byte data range is 0.0 to 8.0.

Python Implementation

import math
from collections import Counter

def shannon_entropy(data):
    freq = Counter(data)
    length = len(data)
    return -sum((c / length) * math.log2(c / length) for c in freq.values())

Entropy Thresholds

Range	Interpretation	Example
0.0-1.0	Nearly uniform	Null files
1.0-4.0	Low entropy	Plain text
4.0-6.0	Mixed content	Office docs
6.0-7.0	Compressed	PDF
7.0-7.5	Highly compressed	ZIP JPEG
7.5-7.9	Block cipher encrypted	AES-CBC
7.9-8.0	Stream cipher encrypted	AES-CTR ChaCha20

psutil Process IO Monitoring

import psutil
proc = psutil.Process(pid)
io = proc.io_counters()
# Fields: read_bytes write_bytes read_count write_count

Behavioral Scoring

Signal	Weight	Threshold
Files modified per min	30 pts	Over 50
Entropy delta	30 pts	Over 3.0
Extension changes	20 pts	Over 10
Ransom note creation	20 pts	Any

Score Interpretation

Score	Severity	Action
0-25	INFO	Log
25-50	LOW	Alert SOC
50-75	HIGH	Suspend process
75-100	CRITICAL	Kill and isolate

Shadow Copy Deletion

Command	Method
vssadmin delete shadows /all /quiet	VSS Admin
wmic shadowcopy delete	WMI
bcdedit /set recoveryenabled no	Disable recovery
wbadmin delete catalog -quiet	Delete backup

watchdog Library

Method	Trigger
on_created	File created
on_modified	File modified
on_deleted	File deleted
on_moved	File renamed

Double Extension Detection

parts = filename.rsplit(".", 2)
if len(parts) >= 3:
    original_ext = "." + parts[-2]
    appended_ext = "." + parts[-1]
