 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).

+## [6.1.0] - 2026-04-10
+
+### Added
+- **`--fail-on <severity>` flag** — CI-friendly exit codes: exit 1 when any finding at or above the specified severity exists (critical/high/medium/low). Configurable via `policy.json` `ci.failOn`
+- **`--compact` output mode** — One-liner per finding format (`[SEVERITY] scanner: title (file:line)`), reduces CI log noise. Configurable via `policy.json` `ci.compact`
+- **CI/CD pipeline templates** — Ready-to-use templates in `ci/`: GitHub Actions (`github-action.yml`), Azure DevOps (`azure-pipelines.yml`), GitLab CI (`gitlab-ci.yml`) with SARIF upload, Node 18 setup
+- **CI/CD integration guide** — `docs/ci-cd-guide.md` with 5-minute setup per platform, Schrems II/NSM compliance documentation, exit code reference
+- **npm publish preparation** — `files` whitelist in `package.json` (only `bin/` + `scanners/`), `.npmignore` safety net, `homepage` field
+- **Policy `ci` section** — New `ci: { failOn, compact }` section in `.llm-security/policy.json` for distributable CI configuration
+
+### Changed
+- Version bump: 6.0.0 → 6.1.0 across all files

+# CI/CD Integration Guide
+
+Integrate llm-security into your CI/CD pipeline for automated security scanning of AI/LLM projects. The standalone CLI runs 10 deterministic Node.js scanners — no AI models, no external API calls, no data leaves your pipeline environment.
+
+## Data Sovereignty
+
+**The standalone CLI makes zero network calls by default.** All 10 scanners operate locally on your source code using Shannon entropy analysis, regex pattern matching, AST traversal, and git log parsing. No data is transmitted to any external service.
+
+**Exception: supply-chain-recheck** — When scanning lockfiles for known vulnerabilities, this scanner optionally queries the [OSV.dev](https://osv.dev/) batch API. This sends only package names and versions (not source code) over HTTPS. To disable: set `LLM_SECURITY_SCR_OFFLINE=1`.
+
+**What about Claude Code integration?** The Claude Code plugin (hooks, agents, commands) uses AI models and sends data to Anthropic. These components are **not included** in the standalone CLI. When you run `npx llm-security scan`, only deterministic scanners execute.
+
+### Schrems II / NSM Compliance
+
+- Standalone CLI: **fully compliant** — no cross-border data transfer
+- OSV.dev queries (opt-in): sends package metadata to Google-operated API — evaluate per your organization's data classification
+- Claude Code plugin: sends code context to Anthropic (US) — requires data processing agreement for regulated environments
+
+### Norwegian Regulatory Context
+
+- **NSM Grunnprinsipper:** Automated security scanning fulfills GP 3.1 (vulnerability management) and GP 2.4 (secure development)
+- **Digitaliseringsdirektoratet:** Aligns with recommended practices for AI system development lifecycle security
+- **EU AI Act (expected Aug 2026):** Directly supports Art. 9 (risk management) and Art. 15 (cybersecurity) requirements
+
+## 5-Minute Setup
+
+### GitHub Actions
+
+Copy `ci/github-action.yml` to `.github/workflows/llm-security.yml`:
+
+```yaml
+name: LLM Security Scan
+on: [push, pull_request]
+jobs:
+  security-scan:
+    runs-on: ubuntu-latest
+    permissions:
+      security-events: write
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-node@v4
+        with:
+          node-version: '18'
+      - run: npx llm-security scan . --fail-on high --format sarif --output-file results.sarif
+      - uses: github/codeql-action/upload-sarif@v3
+        if: always()
+        with:
+          sarif_file: results.sarif
+```
+
+SARIF results appear in the repository's **Security** tab under **Code scanning alerts**.
+
+### Azure DevOps
+
+Copy `ci/azure-pipelines.yml` to your pipeline, or include the scan step in an existing pipeline:
+
+```yaml
+steps:
+  - task: NodeTool@0
+    inputs:
+      versionSpec: '18.x'
+  - script: npx llm-security scan . --fail-on high --format sarif --output-file $(Build.ArtifactStagingDirectory)/results.sarif
+    displayName: Run llm-security scan
+  - task: PublishBuildArtifacts@1
+    condition: always()
+    inputs:
+      pathToPublish: $(Build.ArtifactStagingDirectory)/results.sarif
+      artifactName: llm-security-scan
+```
+
+For Azure DevOps Advanced Security, replace `PublishBuildArtifacts@1` with `AdvancedSecurity-Publish@1`.
+
+### GitLab CI
+
+Add to `.gitlab-ci.yml`:
+
+```yaml
+llm-security-scan:
+  image: node:18-alpine
+  stage: test
+  script:
+    - npx llm-security scan . --fail-on high --format sarif --output-file results.sarif
+  artifacts:
+    paths:
+      - results.sarif
+    reports:
+      sast: results.sarif
+    when: always
+```
+
+SAST report parsing requires GitLab Ultimate. On Free/Premium tiers, download the SARIF artifact manually.
+
+## Configuration
+
+### CLI Flags
+
+| Flag | Description |
+|------|-------------|
+| `--fail-on <severity>` | Exit 1 if any finding at or above severity exists. Values: `critical`, `high`, `medium`, `low` |
+| `--compact` | One-liner per finding format. Reduces CI log noise |
+| `--format sarif` | Output OASIS SARIF 2.1.0 (default: JSON) |
+| `--output-file <path>` | Write full results to file. Stdout gets compact aggregate |
+| `--baseline` | Diff against stored baseline (show new/resolved findings) |
+| `--save-baseline` | Save current results as baseline for future diffs |
+
+### Policy File
+
+Configure defaults in `.llm-security/policy.json`:
+
+```json
+{
+  "ci": {
+    "failOn": "high",
+    "compact": true
+  }
+}
+```
+
+CLI flags always take precedence over policy file values.
+
+### Environment Variables
+
+| Variable | Description |
+|----------|-------------|
+| `LLM_SECURITY_SCR_OFFLINE=1` | Disable OSV.dev network calls in supply-chain-recheck |
+| `LLM_SECURITY_AUDIT_LOG=<path>` | Write structured JSONL audit trail (SIEM-ready) |
+
+## Exit Codes
+
+| Code | Meaning | When |
+|------|---------|------|
+| `0` | Clean / below threshold | No findings at or above `--fail-on` level, or ALLOW verdict |
+| `1` | Threshold exceeded | Findings at or above `--fail-on` level, or WARNING verdict (without `--fail-on`) |
+| `2` | Block | BLOCK verdict (only without `--fail-on`) |
+
+With `--fail-on`, exit codes are binary: 0 (clean) or 1 (threshold exceeded). Without `--fail-on`, the legacy tri-state (0/1/2) is preserved.
+
+## What Gets Scanned
+
+The 10 deterministic scanners cover:
+
+| Scanner | Detects |
+|---------|---------|
+| Unicode | Zero-width characters, homoglyphs, Unicode Tag steganography |
+| Entropy | High-entropy strings (potential secrets/tokens) |
+| Permission | Overly broad permissions, missing tool justification |
+| Dependency | Known vulnerable packages, typosquats |
+| Taint | Untrusted input flows to sensitive operations |
+| Git forensics | Force pushes, sensitive file history, author anomalies |
+| Network | Suspicious URLs, exfiltration endpoints, C2 patterns |
+| Memory poisoning | Injection patterns in CLAUDE.md, memory files, rules |
+| Supply chain | Lockfile audit, blocklists, OSV.dev (opt-in) |
+| Toxic flow | Lethal trifecta correlation (input + access + exfil) |
+
+## Local Testing
+
+Test the exact same command locally before adding to CI:
+
+```bash
+# With npx (requires npm publish)
+npx llm-security scan . --fail-on high --compact
+
+# With local clone
+node bin/llm-security.mjs scan . --fail-on high --compact
