-# CROVIA CEP Capsules
+# CROVIA – CEP Capsules (`crovia_cep_capsule.v1`)
 
-Each file in this dataset is a `crovia_cep_capsule.v1` evidence block.
+This dataset contains **CROVIA CEP Capsules**: compact, hash-addressable
+evidence objects that summarise one full C-Line run for a given period.
 
-A CEP Capsule is a compact, signed evidence object summarising:
-- attribution logs (royalty_receipt.v1)
-- payouts per provider (payouts.v1)
-- trust bundle (trust_bundle.v1)
-- hash-chain evidence
-- AI Act documentation
+Each file is a JSON object with schema:
 
-In the future you will be able to verify a capsule locally with:
+- `schema: "crovia_cep_capsule.v1"`
+- a human-readable `fingerprint` (CEP-YYYYMM-XXXXXX)
+- model metadata
+- pointers and SHA-256 hashes for:
+  - royalty receipts (`royalty_receipt.v1`)
+  - payouts (`payouts.v1`)
+  - hash-chain proofs
+- C-Line configuration and summary metrics.
+

+## 📦 Current capsules

+- `CEP-2511-K4I7X2` – demo C-Line run for period **2025-11**  
+  (4 providers, 200 receipts, €1M budget, Gini ≈ 0.16, data health = A)
+

+
+## 🔍 Verify locally with `cep`
+
+You can verify this capsule locally with the `crovia-cep` CLI:
 
 ```bash
-pip install crovia-cep
+# inside your Python env
+pip install -e .  # from the crovia-cep repo
+
 cep CEP-2511-K4I7X2

+model      crovia-llm-demo
+period     2025-11
+providers  4      receipts  200    gini  0.16
+health     A      AI Act Annex IV ready
+This means:
+
+the capsule could be downloaded and parsed
+
+the C-Line metrics match the evidence attached to the capsule
+
+🔧 Use this pattern for your own runs
+For any future period YYYY-MM, you can create a new capsule:
+
+CEP-YYYYMM-XXXXXX.json in this dataset
+
+containing:
+
+a pointer to the receipts NDJSON
+
+a pointer to the payouts NDJSON
+
+a pointer to the hash-chain proof
+
+C-Line parameters and summary metrics
+
+Once pushed here, one command is enough to check it:
+
+```bash
+Copia codice
+cep CEP-YYYYMM-XXXXXX
