+# Edge Sync Completion Status
+
+**Status:** Complete for the planned Edge/S3 Sync implementation brief  
+**Branch:** `main`  
+**Governing docs:**
+- [`edge-s3-persistence.md`](./edge-s3-persistence.md)
+- [`edge-sync-artifact-contract.md`](./edge-sync-artifact-contract.md)
+- [`edge-sync-implementation-brief.md`](./edge-sync-implementation-brief.md)
+
+## Summary
+
+The Edge/S3 Sync track is complete for the planned six-slice scope defined in `edge-sync-implementation-brief.md`.
+
+```text
+Docs complete:                    3/3
+Implementation slices complete:   6/6
+Runtime integration:              intentionally not started
+Live network tests:               prohibited
+S3 in hot path:                   prohibited
+Credentials in repo:              prohibited
+Automatic epistemic promotion:    prohibited
+```
+
+The implementation establishes local contracts, validation, activation, journaling, an object-store seam, and an optional S3-compatible adapter. It does not integrate cloud/object storage into CORE's active cognition path.
+
+## Completed documents
+
+| Document | Status | Purpose |
+|---|---:|---|
+| `edge-s3-persistence.md` | Complete | Defines the edge-local / S3-cold split. |
+| `edge-sync-artifact-contract.md` | Complete | Defines artifact classes, authority boundaries, manifests, and sync semantics. |
+| `edge-sync-implementation-brief.md` | Complete | Defines the six-slice implementation plan. |
+
+## Completed implementation slices
+
+| Slice | Status | Files |
+|---|---:|---|
+| ES-0 / ES-1 — artifact authority model + contract tests | Complete | `core/sync/artifacts.py`, `tests/test_edge_sync_artifact_contract.py` |
+| ES-2 — manifest parser/validator | Complete | `core/sync/manifest.py`, `tests/test_edge_sync_manifest.py` |
+| ES-3 — activation ledger | Complete | `core/sync/activation.py`, `tests/test_edge_sync_activation.py` |
+| ES-4 — local sync journal | Complete | `core/sync/journal.py`, `tests/test_edge_sync_journal.py` |
+| ES-5 — object-store adapter seam | Complete | `core/sync/object_store.py`, `tests/test_edge_sync_hot_path_imports.py` |
+| ES-6 — optional S3 adapter | Complete | `core/sync/s3_store.py`, `tests/test_edge_sync_s3_store.py` |
+
+Package exports are collected in:
+
+```text
+core/sync/__init__.py
+```
+
+## Invariants now represented in code/tests
+
+The completed implementation codifies these rules:
+
+```text
+Downloaded != activated.
+Activated  != coherent.
+Signed     != true.
+```
+
+And proves:
+
+- artifact authority classes are closed;
+- no edge-sync artifact is hot-path allowed;
+- runtime-affecting artifacts require signature and activation;
+- signed artifacts do not become admissible evidence by signature alone;
+- fleet observations remain speculative unless promoted through proof/review;
+- unknown artifact types reject;
+- unsupported manifest schema versions reject;
+- hash mismatch rejects;
+- missing content digest rejects when bytes are supplied;
+- malformed epistemic status defaults to speculative;
+- downloaded artifacts remain inert until activated;
+- activation does not confer evidence authority;
+- activation and rollback emit audit records;
+- local journal failures preserve retryable local state;
+- hot-path packages are statically guarded from object-store/S3 imports;
+- optional S3 behavior is tested with an injected fake client only.
+
+## Verification command
+
+Run the Edge/S3 Sync test set with:
+
+```bash
+pytest \
+  tests/test_edge_sync_artifact_contract.py \
+  tests/test_edge_sync_manifest.py \
+  tests/test_edge_sync_activation.py \
+  tests/test_edge_sync_journal.py \
+  tests/test_edge_sync_hot_path_imports.py \
+  tests/test_edge_sync_s3_store.py
+```
+
+## Scope intentionally not implemented
+
+The following remain out of scope for this completed slice:
+
+- live S3 credentials;
+- live bucket access;
+- background sync daemon;
+- multipart upload;
+- object-lock enforcement;
+- fleet aggregation logic;
+- runtime pack activation against real pack stores;
+- motor/safety integration;
+- automatic teaching-pack promotion;
+- cloud-driven serving mutation;
+- S3/object-store calls from hot-path cognition.
+
+Any of the above requires a follow-on ADR, implementation brief, or explicit continuation plan.
+
+## Hot-path boundary
+
+The current static guard covers these hot-path directories:
+
+```text
+algebra/
+chat/
+generate/
+vault/
+core/physics/
+```
+
+They must not import:
+
+```text
+boto3
+botocore
+core.sync.object_store
+core.sync.s3_store
+```
+
+Future hot-path directories should be added to the guard if the runtime boundary expands.
+
+## Completion statement
+
+The Edge/S3 Sync track is complete for the planned local-contract scope.
+
+The result is a safe cloud/fleet persistence foundation that preserves CORE's edge-native law:
+
+```text
+Edge thinks and acts.
+S3 remembers and distributes.
+Truth still enters only by proof.
+```
