+# Compliance Fixtures — NeatCode Setup
+
+Enable these settings on the **devzyai/test-code-review** GitHub installation before opening the compliance fixtures PR.
+
+## Required
+
+1. Open NeatCode **Action Settings** for the `test-code-review` repository.
+2. Turn on **Compliance Review** (`compliance_enabled: true`).
+3. Enable frameworks:
+   - GDPR
+   - OWASP Top 10
+   - PCI DSS
+   - HIPAA
+   - SOX
+
+**Shortcut:** apply the **fintech** or **healthcare** compliance template in settings (covers most rules).
+
+4. Keep default severity levels so **critical** and **high** violations set `action_required: true`.
+
+## Optional (export route extras)
+
+Enable these rules if testing SSRF, path traversal, and command injection in `app/api/workspace/export/route.ts`:
+
+- `owasp-ssrf-user-url`
+- `owasp-path-traversal`
+- `owasp-command-injection`
+
+## Validation
+
+After the PR is reviewed, compare reported `ruleId` values against [`compliance-fixtures-manifest.json`](./compliance-fixtures-manifest.json) and update the `lastRun` section.

 # Compliance Fixtures — NeatCode Setup
 
-Enable these settings on the **devzyai/test-code-review** GitHub installation before opening the compliance fixtures PR.
+Enable these settings on the **test-code-review** GitHub installation before
+opening the fixtures PR (onprem / SaaS Action Settings).
 
 ## Required
 
-1. Open NeatCode **Action Settings** for the `test-code-review` repository.
-2. Turn on **Compliance Review** (`compliance_enabled: true`).
-3. Enable frameworks:
-   - GDPR
+1. Turn on **Compliance Review** (`compliance_enabled: true`).
+2. Enable frameworks:
    - OWASP Top 10
+   - OWASP LLM Top 10
    - PCI DSS
-   - HIPAA
    - SOX
+3. Keep severity filters that include **critical** and **high**.
 
-**Shortcut:** apply the **fintech** or **healthcare** compliance template in settings (covers most rules).
-
-4. Keep default severity levels so **critical** and **high** violations set `action_required: true`.
-
-## Optional (export route extras)
-
-Enable these rules if testing SSRF, path traversal, and command injection in `app/api/workspace/export/route.ts`:
+Optional (already enabled in many onprem templates):
 
 - `owasp-ssrf-user-url`
 - `owasp-path-traversal`
 - `owasp-command-injection`
+- `gdpr-pii-detection` / `gdpr-logging-audit` (individual rules)
+
+## Feature surface in this branch
+
+- Team workspace billing charge + payment helpers
+- Workspace export API
+- Workspace Copilot (`/api/ai/chat` + assistant panel)
 
 ## Validation
 
-After the PR is reviewed, compare reported `ruleId` values against [`compliance-fixtures-manifest.json`](./compliance-fixtures-manifest.json) and update the `lastRun` section.
+After review, compare reported `ruleId` values against
