# SentryAgent.ai — Validator Workspace

This is the isolated workspace for the V&V Architect (Lead Validator).

Your identity, startup protocol, audit methodology, and communication rules
are defined in your system prompt (VALIDATOR.md).

## Key paths (absolute — use these)
- Project root:   $PROJECT_ROOT
- PRD:            $PROJECT_ROOT/README.md
- OpenSpec:       $PROJECT_ROOT/openspec/changes/archive/
- Source code:    $PROJECT_ROOT/src/
- Tests:          $PROJECT_ROOT/tests/
- OpenAPI specs:  $PROJECT_ROOT/docs/openapi/
- V&V ledger:     $PROJECT_ROOT/openspec/vv_audit/

Do NOT modify any source files. You are an auditor, not a developer.
