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: Implementing GCP VPC Firewall Rules

Libraries

google-cloud-compute

Key Classes and Methods

Class Method Description
FirewallsClient list(project) List all firewall rules
FirewallsClient get(project, firewall) Get rule details
FirewallsClient insert(project, firewall_resource) Create rule
FirewallsClient patch(project, firewall, firewall_resource) Update rule
FirewallsClient delete(project, firewall) Delete rule
NetworksClient list(project) List VPC networks

Firewall Rule Object Fields

  • name -- Rule name (unique per project)
  • network -- VPC network path
  • direction -- INGRESS or EGRESS
  • priority -- 0 (highest) to 65535 (lowest)
  • allowed[] -- Protocol and port combinations to allow
  • denied[] -- Protocol and port combinations to deny
  • source_ranges[] -- Source CIDR ranges for ingress
  • destination_ranges[] -- Destination CIDRs for egress
  • target_tags[] -- Network tags to apply rule to
  • source_tags[] -- Source instance tags
  • disabled -- Boolean to disable without deleting
  • log_config.enable -- Enable firewall rule logging

Priority Ranges (Best Practice)

  • 0-999: Emergency/override rules
  • 1000-9999: Organization policies
  • 10000-49999: Application-specific rules
  • 50000-64999: Default deny rules
  • 65534: Implied allow egress (GCP default)
  • 65535: Implied deny ingress (GCP default)

gcloud CLI Equivalents

  • gcloud compute firewall-rules list
  • gcloud compute firewall-rules create NAME --allow tcp:22 --source-ranges 10.0.0.0/8
  • gcloud compute firewall-rules delete NAME
  • gcloud compute firewall-rules update NAME --disabled

Hierarchical Firewall Policies

  • Organization-level: compute.firewallPolicies
  • Folder-level: Applied via compute.firewallPolicies.addAssociation
  • Evaluation order: Organization > Folder > VPC rules
