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: Log Integrity with Blockchain Hash Chaining

hashlib - SHA-256 Hashing

import hashlib
hash_hex = hashlib.sha256("data".encode("utf-8")).hexdigest()
# Returns 64-char hex string

Chain Entry Structure

{
  "index": 0,
  "timestamp": "2024-01-15T10:30:00.000Z",
  "content_hash": "SHA256(log_entry_text)",
  "prev_hash": "0000...0000 (genesis) or previous chain_hash",
  "chain_hash": "SHA256(prev_hash + timestamp + content_hash)",
  "content_preview": "first 200 chars of log entry"
}

Chain Construction Algorithm

genesis_hash = "0" * 64
for each log_entry:
    content_hash = SHA256(log_entry)
    chain_hash = SHA256(prev_hash + timestamp + content_hash)
    store(index, timestamp, content_hash, prev_hash, chain_hash)
    prev_hash = chain_hash

Verification Algorithm

prev_hash = genesis_hash
for each entry in chain:
    expected = SHA256(prev_hash + entry.timestamp + entry.content_hash)
    if expected != entry.chain_hash:
        TAMPER DETECTED at index
    prev_hash = entry.chain_hash

Checkpoint Structure

{
  "timestamp": "2024-01-15T12:00:00Z",
  "chain_length": 1000,
  "head_hash": "chain_hash of last entry",
  "head_index": 999,
  "checkpoint_hash": "SHA256(chain_length + head_hash)"
}

Tamper Detection Properties

  • Modifying any entry invalidates all subsequent chain_hashes
  • First break index identifies the tampered entry
  • Checkpoint comparison detects retroactive modifications
