  • VERSION = v1.0 — basis: First SocioLens materialized record for this Source identity; no predecessor record exists (Publication System Amendment v1.2 §4; ruling-backed production identity materialized under Issue #39).

  • CURRENT_POINTER = true — basis: Publication System Amendment v1.2 §4: the sole SocioLens record version for this Source identity; the materialization manifest explicitly designates SRC-LD07-XIE-SSDATABENCH-2026--v1.0 current.
  • VISIBILITY = PUBLIC_REFERENCE — basis: Explicit public provenance selection by LD07-HQ-C06--v1.0 (Issue #5 proof rendering (Architecture Proof Protocol v0.1 AP-08 / Amendment v1.2 §6): explicit version-pinned public provenance of this ClaimVersion — the pinned field-6 Source record "Xie et al. PNAS 2026"; Drive-derived identity authority (Issue #39 Source inventory): Batch 02 §3; ledger C06; KEY EVIDENCE.) (Amendment v1.2 §4, §6).
