# security-case-types tools

Validator and renderer for SecurityCaseTypes and SecurityCases
(`canon/standards/security-case-types_v0.1.md`, schemas
`canon/schemas/security-case-type_v0.1.schema.json` and
`security-case_v0.1.schema.json`).

```bash
# a type directory: type.yaml, README.md sections, tests, example cases
python3 tools/security-case-types/security_case_validator.py validate-type security-case-types/<type-id>

# a case against its type (security-case-types/<type-id>/type.yaml)
python3 tools/security-case-types/security_case_validator.py validate-case <case.yaml> --types security-case-types

# render a case into the composer's plan plus materialization, follow-through,
# verification and rollback; execution is never permitted
python3 tools/security-case-types/security_case_validator.py render <case.yaml> \
  --types security-case-types capabilities/playbooks/*.yaml
```

Only `implemented` types accept cases. `--allow-unimplemented` exists for a type's
own example cases while the type is being written and acknowledged.

The validator refuses, among other things: missing sections, unknown or unpinned
capabilities, attended steps without justification, steps or materialized items
without a rollback, verification without a negative check or that reads a value,
templates with unknown parameters, credential-shaped values anywhere, secret
parameters that are not custody references, and high-risk types without founder
acceptance.

To start a type: copy `security-case-types/_template/`, rename the directory to
the type id, and rewrite every section. The template's tests travel with it:
rename `tests/test_type.py` to `tests/test_<type_id>_contract.py` so module names stay unique.

Tests: `python3 -m pytest tools/security-case-types/tests security-case-types/*/tests`.
