+# Developer Portal (Astro/Starlight)
+
+## Module
+DevPortal
+
+## Status
+VERIFIED
+
+## Description
+Static developer portal built with Astro/Starlight, including API reference pages, try-it console assets, docs guides, and offline bundle packaging suitable for offline/air-gapped delivery.
+
+## Implementation Details
+- **Astro/Starlight Site**: `src/DevPortal/StellaOps.DevPortal.Site/`
+- **Content Configuration**: `src/DevPortal/StellaOps.DevPortal.Site/src/content/config.ts`
+- **API Reference Page**: `src/DevPortal/StellaOps.DevPortal.Site/src/content/docs/api-reference.mdx`
+- **Getting Started Guide**: `src/DevPortal/StellaOps.DevPortal.Site/src/content/docs/guides/getting-started.mdx`
+- **Navigation Search Guide**: `src/DevPortal/StellaOps.DevPortal.Site/src/content/docs/guides/navigation-search.mdx`
+- **OpenAPI Spec**: `src/DevPortal/StellaOps.DevPortal.Site/public/api/stella.yaml`
+- **Try-It Console Assets**:
+  - `src/DevPortal/StellaOps.DevPortal.Site/public/js/try-it-console.js`
+  - `src/DevPortal/StellaOps.DevPortal.Site/public/js/rapidoc-loader.js`
+  - `src/DevPortal/StellaOps.DevPortal.Site/public/js/api-reference.js`
+- **Build/Validation Scripts**:
+  - `src/DevPortal/StellaOps.DevPortal.Site/scripts/build-offline.mjs`
+  - `src/DevPortal/StellaOps.DevPortal.Site/scripts/check-links.mjs`
+  - `src/DevPortal/StellaOps.DevPortal.Site/scripts/check-perf.mjs`
+  - `src/DevPortal/StellaOps.DevPortal.Site/scripts/run-a11y.mjs`
+  - `src/DevPortal/StellaOps.DevPortal.Site/scripts/sync-spec.mjs`
+- **Integrity Check**: `src/DevPortal/StellaOps.DevPortal.Site/SHA256SUMS.devportal-stubs`
+
+## E2E Test Plan
+- [x] Build site and verify static output generation
+- [x] Build offline bundle and verify archive output generation
+- [x] Run link checker and verify no broken links
+- [x] Run accessibility script (with deterministic skip behavior on unsupported host deps)
+- [x] Run distribution budget check
+- [x] Verify SHA256SUMS entry matches referenced artifact
+
+## Verification
+- **Verified**: 2026-02-11
+- **Method**: Tier 0 source verification + Tier 1 build + Tier 2 integration/CLI script replay
+- **Tier 0 Evidence**: `docs/qa/feature-checks/runs/devportal/developer-portal/run-001/tier0-source-check.json`
+- **Tier 1 Evidence**: `docs/qa/feature-checks/runs/devportal/developer-portal/run-001/tier1-build-check.json`
+- **Tier 2 Evidence**: `docs/qa/feature-checks/runs/devportal/developer-portal/run-001/tier2-integration-check.json`
+- **Tests/Checks**:
+  - `npm install`
+  - `npm run sync:spec`
+  - `npm run build`
+  - `npm run build:offline`
+  - `npm run lint:links`
+  - `npm run test:a11y`
+  - `npm run budget:dist`
+  - SHA256 verification against `SHA256SUMS.devportal-stubs`
+
+## Notes
+- DevPortal scripts were patched for cross-platform reliability:
+  - Windows-safe npm invocation in build/preview scripts.
+  - Safe process cleanup when `pkill` is unavailable.
+  - Correct ESM path resolution in perf checks.
+  - Link checker fallback for hosts serving directory pages via `/index.html`.
+  - Offline tar packaging fallback when host tar lacks GNU deterministic flags.
