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 27 — Provenance DAG — Who Touched What, Provably
+
+**Fingerprint:** `23064887b1469b19fa562e8afdee5e9046bedf99aa9cd7142c35e38f91e6fef2`
+
+## Aim
+Maintain an immutable history of data and model lineage with cryptographic integrity.
+
+## Core
+- Model each transformation as a node \(v\) in a DAG with incoming edges from its inputs.
+- Hash node contents so any tampering breaks path verification.
+- Sign lineage updates and anchor digests to transparency logs for public verification.
+
+## Runbook
+1. Hash inputs, code, and environment metadata; sign and append new nodes to the provenance graph.
+2. Support impact analysis via graph reachability and automate recalls of contaminated outputs.
+3. Periodically anchor the DAG root hashes to append-only transparency or blockchain logs.
+
+## Telemetry
+- Latency of path verification queries.
+- Count of orphan nodes or unverifiable edges.
+- Time to recall or quarantine affected outputs.
+
+## Failsafes
+- Block publication of artifacts with unverifiable provenance paths.
+- Quarantine entire subtrees when signatures or hashes mismatch expectations.
+
+**Tagline:** Every lineage, logged and locked.
