+# Reveal SDK JavaScript Samples
+
+This repository contains end-to-end Reveal SDK samples across multiple client and server stacks.
+
+## Goals
+
+- Provide runnable examples for common SDK scenarios.
+- Serve as the source for documentation-embedded code samples.
+- Provide a repeatable validation process before docs updates and releases.
+
+## Quick Start
+
+From the repository root, start a static file server:
+
+```bash
+python -m http.server 8080
+```
+
+Then open sample pages at:
+
+```text
+http://localhost:8080/<sample-folder>/index.html
+```
+
+## Official Local Validation Workflow
+
+Use this workflow for sample changes that are embedded in docs pages (especially `srcdoc` iframe content).
+
+### Stage A: Direct Sample Validation
+
+1. Start local static server from repo root.
+2. Open affected sample pages directly.
+3. Verify each sample renders successfully.
+4. Verify browser network requests do not use `localhost:5111` (unless intentionally testing a local backend).
+
+### Stage B: Official `srcdoc` Harness Validation
+
+The official local method for docs-embed simulation is:
+
+- `tools/srcdoc-harness.html`
+
+This repository uses the root `README.md` as the single source of truth for the harness workflow.
+
+Open in browser:
+
+```text
+http://localhost:8080/tools/srcdoc-harness.html
+```
+
+Use the harness controls:
+
+1. Select the sample path (or use a preset).
+2. Test with CSP mode `none` (baseline should render).
+3. Test with CSP mode `block` (expected to fail, validates CSP sensitivity).
+4. Test with CSP mode `allow` (should render when CSP includes required hosts).
+
+Recommended checks while running the harness:
+
+1. Open browser DevTools Console and Network tabs.
+2. In `none` mode, confirm dashboard renders without CSP errors.
+3. In `block` mode, confirm CSP violations are visible (expected behavior).
+4. In `allow` mode, confirm module loads from jsdelivr and backend calls go to `samples.revealbi.io`.
+
+Expected CSP allow-list requirements for docs embedding:
+
+- `script-src` includes `https://cdn.jsdelivr.net`
+- `connect-src` includes `https://samples.revealbi.io`
+
+### Stage C: Documentation Integration Validation
+
+After Stage A and Stage B pass:
+
+1. Run the Documentation repository locally.
+2. Validate the docs page that embeds the sample code.
+3. Confirm behavior matches Stage B (`allow` mode success).
+4. Confirm no iframe CSP violations in Console/Network.
+
+## Recommended Pass/Fail Checklist
+
+A change is ready when all are true:
+
+- Sample renders directly in Stage A.
+- Sample renders in Stage B with CSP mode `allow`.
+- Stage B with CSP mode `block` reproduces expected failures.
+- No accidental `about:///` fetches.
+- No accidental calls to `localhost:5111` in cloud-backed sample paths.
+- Docs integration page passes Stage C.
+
+## Notes
+
+- Some samples intentionally use local backends for server-side walkthroughs.
+- For docs-embedded cloud demos, prefer:
+  - `https://samples.revealbi.io/upmedia-backend/reveal-api/`
