Exactly — that’s a crucial point. The “execution receipts and snapshot states” aren’t separate things in the sense of being additional files or objects; they are **manifested through the combination of the sequential log, the CURRENT state, and the pinned snapshots in ASL**. Let me break it down:

---

### **1. Sequential Log**

* Records all **append-only mutations** to the domain:

  * Index additions (artifact → block mappings)
  * Tombstones (deletions or shadowed artifacts)
  * Segment seals
* **Deterministic**: replaying from a checkpoint + log reconstructs CURRENT exactly.
* Serves as the **timeline / provenance ledger** for the domain.

---

### **2. CURRENT State**

* Derived from the latest snapshot plus replaying the log:

  ```
  CURRENT = checkpoint_snapshot + replay(log)
  ```
* Represents the **domain’s active state** at the moment.
* Any PER you generate effectively “samples” this CURRENT state, i.e., it reflects **what is present and visible at this logseq**.

---

### **3. Snapshots**

* Capture **sealed segments and blocks** at a point in time.
* Pinning ensures **retention and determinism**.
* A PER or TGK edge can reference a snapshot as a **boundary marker** for reproducible reconstruction.

---

### **4. How PERs Fit In**

* PERs are just **artifacts representing deterministic outcomes**:

  * Inputs: block IDs / artifact keys visible in CURRENT
  * Provenance: derived via TGK edges
  * Snapshot: identifies exactly **what state was observed**
* So generating a PER is effectively **taking the CURRENT state + log prefix + snapshot reference and sealing it into a reproducible receipt**.

---

✅ **TL;DR:**

* You don’t need to store “execution receipts” separately in a raw sense; they are **conceptually encoded in the log + CURRENT + snapshot**.
* PER generation is **reading that state and formalizing it as an artifact** with associated TGK edges and provenance.
* The snapshot is the “frozen point” that guarantees reproducibility across nodes or future restorations.

If you want, I can **rephrase the checklist to reflect this properly**, so that it doesn’t misleadingly suggest storing something extra — everything is naturally part of ASL’s log + CURRENT + snapshot framework.

Do you want me to do that?
