# CASAN Higher-Level Criteria

## Level 1 - Curious

Minimum signs:

- Individual AI usage.
- No shared prompt library.
- No audit log.
- No official governance.

## Level 2 - Augmented

Minimum signs:

- Approved AI tools are used by teams.
- Some workflow productivity gain.
- Basic acceptable-use policy.
- Vendor-provided safety controls.

## Level 3 - Standard

Minimum signs:

- Shared AI-SDLC process.
- Reusable templates and agent definitions.
- Review gates.
- Basic context management.
- Repeatable test and review flow.

## Level 4 - Automated

Minimum signs:

- Multi-step workflow is agent-orchestrated.
- H4 Security, H5 Governance, and H6 AgentOps are automated runtime gates.
- Side-effecting actions have policy decisions and audit evidence.
- Prompt injection, PII leakage, and secret exposure are tested.
- Trace, metrics, cost, latency, retry, and failure alerts are captured.
- Human approval exists for high-risk actions but is non-interactive and auditable.

## Level 5 - Native

Minimum signs:

- Harness is reusable across projects and business domains.
- Agent workflows improve based on measured outcomes.
- Model fallback, drift detection, rollback, and self-healing are operational.
- Governance, security, and AgentOps are centralized across teams.
- Business KPIs are tied to agent decisions and quality gates.
- Human-led, AI-first delegation is explicit by risk tier.

## Concrete Level 5 Backlog

| Area | Level 5 requirement | Suggested implementation |
|---|---|---|
| Drift Detection | Detect behavior changes across model/prompt versions | Store golden run outputs and compare semantic/structural deltas on every run |
| Model Fallback | Route failed or low-confidence steps to another model/tool path | Add policy-based fallback matrix: primary model, fallback model, max retry, risk tier |
| Tool Registry | Central registry for all side-effecting tools | Add `tool-registry.yaml` with schema, owner, risk level, idempotency key, timeout, rollback |
| Rollback | Recover from failed write/deploy/db steps | Add transaction boundary records and rollback scripts for `write_code`, `migration`, `deploy` |
| Business Feedback | Optimize based on business outcomes, not only technical metrics | Track cycle time, defect leakage, review rejection rate, manual rework hours |
| Harness Registry | Reuse harness modules across projects | Package H4/H5/H6 as versioned shared assets with changelog and compatibility contract |
| Central AgentOps | Aggregate traces across teams/projects | Send trace/metrics JSONL to a central dashboard or log platform |
| Governance Federation | Cross-project policy enforcement | Use signed policy bundles and a centralized approval identity provider |
| Self-Healing | Agent can choose bounded recovery path | Add failure classifier, remediation playbooks, and max retry/backoff policy |
| Continuous Evaluation | Evaluation improves with production feedback | Convert incidents and reviewer comments into golden tests automatically |

## Level 5 Exit Criteria

- At least two projects use the same versioned Harness package.
- A golden dataset detects drift before production execution.
- A failed model/tool path successfully falls back without bypassing governance.
- A side-effecting failure demonstrates rollback.
- Business KPI report shows before/after improvement.
- Central dashboard shows cost, latency, failure, rejection, and drift trends.
- Policies are signed or centrally controlled, not locally editable only.

## Level 5 Status

This package now provides **Level 5 demonstration evidence** and working local implementations for the core Level 5 mechanisms. It should be presented as:

- Level 4: achieved.
- Level 5: demonstrated in a local/file-based environment.

To claim full enterprise production Level 5 outside this local package, connect these mechanisms to enterprise services: organization identity provider, WORM/signed log storage, real LLM provider usage APIs, and a deployed shared dashboard.
