The source of curvature comes from an anisotropic fluid with $p_{r} = -\\rho$ and fluctuating tangential pressures. The event horizon has zero surface gravity but the invariant acceleration of a static observer is finite there. The Tolman - Komar energy of the gravitational fluid changes sign on the horizon, equals the black hole mass at infinity and is vanishing at $r = 0$. There is a nonzero surface stress tensor on the horizon due to a jump of the extrinsic curvature. Near-horizon geometry resembles the Robinson - Bertotti metric "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1305.5964","kind":"arxiv","version":6},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
