+# SBOM Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Generate comprehensive SBOMs (CycloneDX 1.6, SPDX 2.3 JSON, SPDX 2.3 tag-value, and Markdown) for all cveClient runtime and dev components, automated via GitHub Actions.
+
+**Architecture:** A modular Node.js generator under `scripts/sbom/` extracts component data from project source files, then serializes to four output formats in `docs/sbom/`. A GitHub Action runs the generator on relevant file changes and opens a PR via `gh`.
+
+**Tech Stack:** Node.js (built-in `fs`, `path`, `crypto`), Vitest (testing), `npx ajv-cli` (CI validation), GitHub Actions + `gh` CLI (automation).

+```
+
+**Why `.mjs` for scripts:** The project's `package.json` has no `"type": "module"`, so `.mjs` enables ESM imports without affecting existing code. Test files stay `.js` since vitest handles ESM natively.

+### Task 1: Component Data Extraction Module
+
+**Files:**
+
+- Create: `scripts/sbom/extract.mjs`
+- Create: `tests/sbom/extract.test.js`
+
+This is the core module - it reads project files and returns structured component inventories.
+
+- [ ] **Step 1: Write failing tests for HTML CDN extraction**

+# SBOM Feature Design Spec — cveClient
+
+**Date:** 2026-04-02
+**Issue:** https://github.com/CERTCC/cveClient/issues/53
+**Status:** Draft
+
+## Goal
+
+Add a comprehensive Software Bill of Materials (SBOM) to cveClient that identifies all components, dependencies, and tooling used in the project. The SBOM serves both security/compliance auditors (machine-readable formats) and developers (human-readable summaries).
+
+## Scope
+
+### Runtime SBOM
+
+Components that ship to end users in the browser:
+
+**Core application files:**
+
+- `cveInterface.js` (v1.0.25)
+- `cveClientlib.js` (v1.0.25)
+- `schemaToForm.js` (v1.0.10)
+- `autoCompleter.js` (v1.0.12)
+- `encrypt-storage.js` (v1.1.15)
+- `cveInterface.css` (v1.0.12)
+
+**CDN dependencies (with SRI hashes):**
+
+- jQuery 3.5.1
+- Bootstrap 4.3.1 (CSS + JS)
+- Popper.js 1.14.7
+- Bootstrap-Table 1.19.1 (CSS + JS)
+
+**Vendored dependencies:**
+
+- Ace Editor ~1.2.4 (Apache-2.0)
+- SweetAlert2 11.26.24 (MIT)
+
+**Schema/data files:**
+
+- CVE JSON 5.0 schema files (`schema/` directory)
+- `cwe-common.json`
+- `language-codes.json`
+
+### Dev SBOM
+
+Components used for development, testing, and CI/CD:
+
+**npm dev dependencies:**
+
+- vitest 3.2.4 + transitive deps
+- jsdom 26.1.0 + transitive deps
+
+**CI/CD toolchain:**
+
+- GitHub Actions workflow files (`.github/workflows/`)
+- Referenced Actions (e.g., `actions/checkout`, `actions/setup-node`)
+- The SBOM generator script itself
+
+## Output Files
+
+All outputs go to `docs/sbom/`:
+
+| File                     | Format             | Purpose                                                    |
+| ------------------------ | ------------------ | ---------------------------------------------------------- |
+| `cyclonedx-runtime.json` | CycloneDX 1.6 JSON | Machine-readable runtime SBOM for scanners/tooling         |
+| `cyclonedx-dev.json`     | CycloneDX 1.6 JSON | Machine-readable dev SBOM for scanners/tooling             |
+| `spdx-runtime.json`      | SPDX 2.3 JSON      | Machine-readable runtime SBOM (ISO standard)               |
+| `spdx-dev.json`          | SPDX 2.3 JSON      | Machine-readable dev SBOM (ISO standard)                   |
+| `spdx-runtime.spdx`      | SPDX 2.3 tag-value | Human-readable standard format for runtime                 |
+| `spdx-dev.spdx`          | SPDX 2.3 tag-value | Human-readable standard format for dev                     |
+| `SBOM.md`                | Markdown           | Summary page for GitHub browsers with links to other files |
+
+### SBOM.md Structure
+
+The markdown file serves as a quick-glance summary and navigation page:
+
+- Project metadata (name, version, license, generation date)
+- Runtime components table (component, version, license, type, source)
+- CDN dependencies table (component, version, source URL, SRI hash, license)
+- Vendored dependencies table (component, version, license)
+- Schema/data files table
+- Dev dependencies summary table
+- CI/CD toolchain table (component, version/ref, purpose)
+- Validation results (CycloneDX and SPDX schema pass/fail)
+- Links to all machine-readable and tag-value files
+
+### CycloneDX JSON Structure
+
+Follows CycloneDX 1.6 specification:
+
+- `bomFormat`: "CycloneDX"
+- `specVersion`: "1.6"
+- `serialNumber`: URN UUID
+- `version`: 1
+- `metadata`: tool info, component (cveClient), timestamp
+- `components[]`: each with type, name, version, purl (for npm packages), cpe (where applicable), licenses, externalReferences (download URLs, SRI hashes)
+
+### SPDX JSON Structure
+
+Follows SPDX 2.3 specification:
+
+- `spdxVersion`: "SPDX-2.3"
+- `dataLicense`: "CC0-1.0"
+- `SPDXID`: "SPDXRef-DOCUMENT"
+- `documentNamespace`: unique URI
+- `name`: document name
+- `packages[]`: each with SPDXID, name, versionInfo, downloadLocation, licenseConcluded, checksums
+- `relationships[]`: DESCRIBES, DEPENDS_ON relationships
+
+### SPDX Tag-Value Structure
+
+Same data as SPDX JSON but in human-readable key-value format:
+
+```
+SPDXVersion: SPDX-2.3
+DataLicense: CC0-1.0
+SPDXID: SPDXRef-DOCUMENT
+DocumentName: cveClient-runtime-sbom
+...
+
+PackageName: jQuery
+SPDXID: SPDXRef-jquery
+PackageVersion: 3.5.1
+PackageDownloadLocation: https://code.jquery.com/jquery-3.5.1.min.js
+PackageLicenseConcluded: MIT
+...
+```
+
+## Generator Script
+
+### Location
+
+`scripts/generate-sbom.js` — a single Node.js script with no external dependencies.
+
+### Data Extraction
+
+The script extracts component information from these sources:
+
+1. **`index.html`** — regex extraction of CDN `<script>` and `<link>` tags to get URLs, versions, and SRI integrity hashes
+2. **`package.json`** — project metadata (name, version, license, repository) and devDependencies
+3. **`package-lock.json`** — resolved versions for dev dependency tree
+4. **Vendored directories:**
+   - `sweetalert2/sweetalert2.all.min.js` — extract version from file header comment
+   - `ace-builds/` — extract version from `ace.js` header or README reference
+5. **Core source files** — extract version constants from each `.js` file via regex
+6. **`cveInterface.css`** — extract version from query parameter in `index.html` or file header
+7. **`schema/`** — list all schema files with descriptions
+8. **`.github/workflows/`** — parse YAML to extract referenced Actions and their versions
+
+### Output Generation
+
+The script builds internal component lists, then serializes to all seven output formats:
+
+1. Build runtime component inventory
+2. Build dev component inventory
+3. Generate CycloneDX 1.6 JSON (runtime + dev)
+4. Generate SPDX 2.3 JSON (runtime + dev)
+5. Generate SPDX 2.3 tag-value (runtime + dev)
+6. Generate SBOM.md summary
+7. Write all seven files to `docs/sbom/`
+
+### Exit Codes
+
+- `0` — success, files written
+- `1` — error (missing source files, parse failures)
+
+Script logs what it found and what it generated to stdout for CI visibility.
+
+## GitHub Action

+    paths:
+      - "index.html"

+
+### Steps
+
+1. **Checkout** — `actions/checkout` with full history
+2. **Setup Node.js** — `actions/setup-node` (match existing CI version)
+3. **Generate SBOMs** — `node scripts/generate-sbom.js`
+4. **Validate CycloneDX** — fetch official CycloneDX 1.6 JSON schema, validate both JSON outputs using `npx ajv-cli validate`
+5. **Validate SPDX** — fetch official SPDX 2.3 JSON schema, validate both JSON outputs using `npx ajv-cli validate`
+6. **Diff check** — compare generated files against existing `docs/sbom/` content; exit early if nothing changed
+7. **Create branch** — `sbom/update-YYYY-MM-DD`
+8. **Commit** — commit all seven updated files
+9. **Push + open PR** — using `gh pr create` with detailed body
+
+### PR Body Format
+
+The PR body will include:
+
+```markdown
+## SBOM Update — YYYY-MM-DD
+
+### Summary
+
+Automated SBOM regeneration triggered by changes to dependency-relevant files.
+
+### Changes Detected
+
+- [list of components added/removed/version-bumped, generated by diffing old vs new]
+
+### Component Counts
+
+| Category         | Runtime | Dev |
+| ---------------- | ------- | --- |
+| Total components | N       | N   |
+| New              | N       | N   |
+| Removed          | N       | N   |
+| Version changed  | N       | N   |
+
+### Validation Results
+
+- CycloneDX 1.6 runtime: PASS/FAIL
+- CycloneDX 1.6 dev: PASS/FAIL
+- SPDX 2.3 runtime: PASS/FAIL
+- SPDX 2.3 dev: PASS/FAIL
+
+### Generated Files
+
+- [`docs/sbom/SBOM.md`](link) — Human-readable summary
+- [`docs/sbom/cyclonedx-runtime.json`](link) — CycloneDX runtime
+- [`docs/sbom/cyclonedx-dev.json`](link) — CycloneDX dev
+- [`docs/sbom/spdx-runtime.json`](link) — SPDX JSON runtime
+- [`docs/sbom/spdx-dev.json`](link) — SPDX JSON dev
+- [`docs/sbom/spdx-runtime.spdx`](link) — SPDX tag-value runtime
+- [`docs/sbom/spdx-dev.spdx`](link) — SPDX tag-value dev
+```
+
+### Permissions
+
+The workflow needs `contents: write` and `pull-requests: write` permissions to create branches and PRs.
+
+## Schema Validation
+
+The CI step validates machine-readable outputs against official schemas:
+
+- **CycloneDX 1.6:** `https://cyclonedx.org/schema/bom-1.6.schema.json`
+- **SPDX 2.3:** `https://raw.githubusercontent.com/spdx/spdx-spec/development/v2.3/schemas/spdx-schema.json`
+
+Validation uses `npx ajv-cli` (no permanent install needed). Validation results are included in both the CI logs and the PR body. Validation failure does NOT block PR creation — the PR is still opened but the failure is prominently noted so it can be addressed in review.
+
+## Component Identification
+
+Where possible, components include standard identifiers:
+
+- **purl** (Package URL) for npm packages: `pkg:npm/vitest@3.2.4`
+- **purl** for CDN components: `pkg:npm/jquery@3.5.1` (since CDN serves npm packages)
+- **CPE** where applicable for well-known libraries
+- **Download URLs** for all external dependencies
+- **SRI hashes** for CDN dependencies (already present in `index.html`)
+- **License identifiers** using SPDX license expression syntax (e.g., `MIT`, `Apache-2.0`)
+
+## Non-Goals
+
+- No runtime SBOM viewer in the web UI (this is repo-level documentation only)
+- No SBOM signing or attestation (can be added later)
+- No automatic vulnerability cross-referencing (leave that to consumers of the SBOM files)
+- No SBOM generation for downstream consumers who use `cveClientlib.js` as a library
