Alexa Louise 9644737ba7 feat: Add domain architecture and extract core services from Prism Console
## Domain Architecture
- Complete domain-to-service mapping for 16 verified domains
- Subdomain architecture for blackroad.systems and blackroad.io
- GitHub organization mapping (BlackRoad-OS repos)
- Railway service-to-domain configuration
- DNS configuration templates for Cloudflare

## Extracted Services

### AIops Service (services/aiops/)
- Canary analysis for deployment validation
- Config drift detection
- Event correlation engine
- Auto-remediation with runbook mapping
- SLO budget management

### Analytics Service (services/analytics/)
- Rule-based anomaly detection with safe expression evaluation
- Cohort analysis with multi-metric aggregation
- Decision engine with credit budget constraints
- Narrative report generation

### Codex Governance (services/codex/)
- 82+ governance principles (entries)
- Codex Pantheon with 48+ agent archetypes
- Manifesto defining ethical framework

## Integration Points
- AIops → infra.blackroad.systems (blackroad-os-infra)
- Analytics → core.blackroad.systems (blackroad-os-core)
- Codex → operator.blackroad.systems (blackroad-os-operator)

Aim

Bound information leakage through timing, power, or electromagnetic side channels.

Core

  • Estimate channel capacity using disturbance bounds: (C \leq \tfrac{1}{2} \log\big(1 + \tfrac{P}{N}\big)).
  • Apply constant-time implementations, randomized blinding, and (d)-order masking to resist (d - 1) probes.
  • Inject controlled noise, power gating, and scheduling jitter to lower signal-to-noise ratios.

Runbook

  1. Classify operations by sensitivity and enforce constant-time code paths.
  2. Introduce noise and flatten power signatures with gating while adding timing jitter.
  3. Validate countermeasures using correlation power analysis (CPA) score thresholds.

Telemetry

  • CPA correlation metrics against target features.
  • Timing variance and electromagnetic signal-to-noise ratios.
  • Success rate of side-channel penetration tests.

Failsafes

  • Disable sensitive features or require HSM execution when CPA exceeds threshold (\tau).
  • Route workloads to hardened hardware whenever noise injections degrade functionality.

Tagline: Silence every leak the sensors can hear.
