- Major updates to README.md and docs/README.md for Pulse v5
- Added technical deep-dives for Pulse Pro (docs/PULSE_PRO.md) and AI Patrol (docs/AI.md)
- Updated Prometheus metrics documentation and Helm schema for metrics separation
- Refreshed security, installation, and deployment documentation for unified agent models
- Cleaned up legacy summary files
High-impact improvements based on Codex recommendations:
1. values.schema.json - JSON schema validation catches config errors at install time
2. helm-docs automation - Auto-generates documentation from values.yaml comments
3. kind smoke tests - Deploys and upgrades chart in real cluster to catch runtime issues
4. ServiceMonitor template - Built-in Prometheus integration for observability
5. Artifact Hub metadata - Changelog, links, and maintainer info for better discoverability
These improvements provide:
- Configuration validation before deployment
- Always up-to-date documentation
- Runtime validation in CI
- First-class monitoring support
- Better user experience on Artifact Hub
