+title: Examples & Snippets
+description: Ready-to-copy requests with deterministic headers and pinned versions.
+---
+
+## cURL quick starts
+
+The snippets below are deterministic: pinned versions, explicit headers, and scope hints.
+
+```bash
+curl -X GET \\
+  https://api.stellaops.local/authority/health \\
+  -H 'Accept: application/json' \\
+  -H 'User-Agent: stellaops-devportal/0.1.0' \\
+  --retry 2 --retry-delay 1
+```
+
+```bash
+curl -X POST \\
+  https://api.stellaops.local/orchestrator/jobs \\
+  -H 'Content-Type: application/json' \\
+  -H 'Authorization: Bearer $STELLAOPS_TOKEN' \\
+  -d '{\"workflow\":\"sbom-verify\",\"source\":\"registry:example/app@sha256:...\"}'
+```
+
+## How snippets are generated
+- Targets align to the aggregate spec (`/api/stella.yaml`).
+- Headers: `Accept`/`Content-Type` always explicit; User-Agent pinned to portal version.
+- Retries kept low (`--retry 2`) to preserve determinism while tolerating transient sandboxes.
+
+## Coming next
+- Language SDK equivalents (DEVPORT-63-002).
+- Operation-specific examples sourced directly from tested fixtures.

+title: Try-It Console
+description: Run authenticated requests against the sandbox API with scoped tokens and offline-ready tooling.
+---
+
+import 'rapidoc/dist/rapidoc-min.js';
+
+> Use this console to exercise the sandbox API. It runs fully client-side with no external assets. Supply a short-lived token with the scopes shown below. Nothing is sent to third-party services.
+
+## Token onboarding
+- Obtain a sandbox token from the Platform sandbox issuer (`/auth/oidc/token`) using the `client_credentials` flow.
+- Required scopes (minimum): `stellaops.read`, `stellaops.write:sandbox`.
+- Tokens should be short-lived (<15 minutes); refresh before each session.
+- Paste only sandbox tokens here—**never** production credentials.
+

+  </div>
+  <p class="hint">Token is stored in-memory only for this tab. Reload to remove.</p>

+
+## Sandbox server
+- Base URL: `https://sandbox.api.stellaops.local`
+- Operations remain namespaced by service (e.g., `/authority/health`, `/orchestrator/jobs`).

+## Tips
+- Set the server dropdown to `https://sandbox.api.stellaops.local` before sending requests.
+- Use small payloads; responses are truncated by RapiDoc if excessively large.
+- Keep retries low to preserve determinism (default is none).

 # stella-forensic-verify (preview)

-Minimal dotnet tool for offline HMAC verification of provenance payloads.
+Minimal .NET 10 global tool for offline verification of provenance payloads signed with an HMAC key. No network access; deterministic JSON output.

 ## Usage

-/mnt/e/dev/git.stella-ops.org /mnt/e/dev/git.stella-ops.org
-/mnt/e/dev/git.stella-ops.org
+```
+stella-forensic-verify \
+  --payload payload.bin       # or '-' to read stdin
+  --signature-hex DEADBEEF... # hex-encoded HMAC
+  --key-hex 001122...         # hex-encoded HMAC key
+  [--key-id hmac]             # optional key id
+  [--content-type application/octet-stream]
+  [--signed-at 2025-11-21T12:00:00Z]
+  [--not-after 2025-12-31T23:59:59Z]
+  [--max-skew-minutes 5]
+```

-Outputs deterministic JSON:
+Output (single line, deterministic field order):

+```
+{"valid":true,"reason":"verified","verifiedAt":"2025-11-22T12:00:00.0000000Z","keyId":"hmac","contentType":"application/octet-stream"}
+```

 ## Exit codes
 - 0: signature valid
- 2: signature invalid
- 1: bad arguments/hex parse failure
+- 2: signature/time invalid
+- 1: bad arguments or hex parse failure
+
+## Offline kit packaging (manual)
+1. `dotnet pack src/Provenance/StellaOps.Provenance.Attestation.Tool/StellaOps.Provenance.Attestation.Tool.csproj -c Release -o out/tools`
+2. Copy the produced nupkg into the offline kit under `tools/`.
+3. Install in air-gap host: `dotnet tool install --global --add-source tools stella-forensic-verify --version <pkg-version>`.
+4. Document expected SHA256 of the nupkg alongside the kit manifest.
