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)

# Codex 14 — Zero-Knowledge Access — Reveal Nothing, Prove Enough
**Fingerprint:** `23064887b1469b19fa562e8afdee5e9046bedf99aa9cd7142c35e38f91e6fef2`
## Aim
Grant access rights based on properties while withholding identity and sensitive attributes.
## Core
- Use zero-knowledge proofs of knowledge to show membership in policy predicates without revealing the witness: \(\text{ZKPoK}\{w : H(w) = c \wedge P(w) = 1\}\).
- Apply group or ring signatures to provide signer anonymity with optional linkability.
- Log nullifiers or other one-time tokens to prevent reuse without deanonymizing.
## Runbook
1. Define the policy predicate \(P\) and issue credentials that commit to \(c\).
2. At access time, present a zero-knowledge proof that \(P(w)\) holds while revealing no personally identifiable information.
3. Record a nullifier or serial number to detect double-spend or abuse attempts.
## Telemetry
- Proof acceptance rate and average generation time.
- Distribution of nullifier usage and collision monitoring.
- Credential issuance and revocation volume.
## Failsafes
- If the policy predicate drifts or becomes stale, hot-patch it and force credential refresh.
- Escalate to step-up authentication (such as device attestation) after repeated proof failures or suspected abuse.
**Tagline:** Permissions by proof, not by passport.
