# Small SaaS Profile Proof

**Workplan:** ITC-WP-0004
**Profile:** `small-saas`
**Status:** executable proof

## Purpose

The `small-saas` profile demonstrates that the canon can guide a practical
service shape before the larger CARING benchmark exists. It connects service
ownership, users, tenants, access, data, runtime, deployment, governance,
observability, and task tracking.

## Validation Surface

```bash
PYTHONPATH=src python3 -m info_tech_canon profile inspect small-saas
PYTHONPATH=src python3 -m info_tech_canon profile validate small-saas
PYTHONPATH=src python3 -m info_tech_canon profile graph small-saas
```

## Graph Slice

The profile graph includes the profile artifact, the small SaaS example
artifacts, and their direct canon anchors.

## Result

The proof is suitable as a baseline for the upcoming `user-engine` evaluation
pack and for `railiance-fabric` entity/edge capture comparisons.
