giles	eda6806989	sx-git Phase 3: commit DAG — log/ancestry/merge-base SX-side + Datalog bridge (TDD) ... Topo log = reverse DFS postorder over parent edges from commit objects; reflexive is-ancestor?, all-LCA merge-bases (criss-cross verified). Datalog bridge exports (git-parent child parent) facts under a minimal 2-rule ancestor closure, cross-checked against the SX walk. 30/30, total 106/106.

giles	74c2521926	sx-git Phase 2: refs — branches/tags/HEAD over persist kv, CAS + reflog (TDD) ... Ref value = {:cid} | {:symref}; atomic moves via persist/kv-cas old-value expect, create-only branches via kv-put-new; bounded symref resolution; per-ref append-only reflog on the persist log facet. 38/38, total 76/76.

giles	9a85b52d1a	sx-git Phase 1: blob/tree/commit/tag as content-addressed typed objects (TDD) ... Objects are plain dicts over persist kv, addressed by sx1:<sha256> of the artdag/canon canonical form (sorted dict keys) — native CIDs, extensible fields participate in identity. 38/38.
