+# Five-minute reviewer path
+
+This path checks the integrity and internal consistency of the released
+synthetic fixture bundle. It does **not** evaluate a provider or establish a
+security, conformance, or certification outcome.
+
+## 1. Download and extract the synthetic fixture bundle
+
+Download the bundle linked from the dataset card, then extract it in an empty
+directory. The bundle contains synthetic data only.
+
+## 2. Verify the bundle before using it
+
+```bash
+python3 scripts/verify_bundle_manifest.py
+```
+
+This checks every bundled file's SHA-256 digest, byte size, and expected file
+set against `bundle-manifest.json`. A mismatch is a stop condition.
+
+## 3. Validate the profile and viewer index
+
+```bash
+python3 scripts/validate_profile.py
+python3 scripts/validate_viewer_split.py
+```
+
+The first validator binds the Markdown coverage matrix to the profile and
+complete synthetic run. The second binds every flat viewer row to that run.
+
+## 4. Inspect one receipt
+
+Open `examples/synthetic-characterization.json` and inspect an observation, or
+paste a redacted observation into the Field Guide's browser-only Receipt
+Inspector. The Inspector checks structural completeness only. It does not
+verify evidence bytes, target authorization, target behavior, or any external
+security outcome.
+
+## 5. State only the supported conclusion
+
+After all checks pass, the supported conclusion is limited to: the downloaded
+synthetic profile artifacts are internally consistent with their declared
+version and manifest. It is not a claim about a provider, an untested
+environment, or the absence of undiscovered authority paths.
