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.

Workflow - Image Provenance with Cosign

Phase 1: Setup

  1. Install cosign CLI
  2. Choose signing method: keyless (recommended) or key-based
  3. If key-based: generate keys, store private key in KMS
  4. Configure CI/CD OIDC token for keyless signing

Phase 2: Build Pipeline Integration

  1. Build container image
  2. Push to registry (by digest)
  3. Sign image with cosign (keyless or key-based)
  4. Generate SBOM with syft
  5. Attach SBOM as attestation
  6. Attach vulnerability scan as attestation

Phase 3: Admission Enforcement

  1. Deploy policy-controller or Kyverno
  2. Create ClusterImagePolicy requiring signatures
  3. Test with signed image (should pass)
  4. Test with unsigned image (should be denied)
  5. Enable enforcement in production namespaces

Phase 4: Verification

# Manual verification
cosign verify --certificate-identity=CI_IDENTITY \
  --certificate-oidc-issuer=ISSUER \
  IMAGE@DIGEST

# Verify SBOM attestation
cosign verify-attestation --type cyclonedx \
  --certificate-identity=CI_IDENTITY \
  --certificate-oidc-issuer=ISSUER \
  IMAGE@DIGEST

Phase 5: Monitoring

  1. Check Rekor transparency log for audit trail
  2. Monitor admission controller deny events
  3. Alert on unsigned image deployment attempts
