GitHub reports a 5,000 concurrent agent and 7,200 pushes/second INTERNAL stress test, and limited private preview rather than general availability. The technical publication and limited preview are the milestone; internal test capacity is not independently verified production performance or a broadly shipped feature.","creator_entities":[],"released_at":"2026-11-05T00:00:00.000Z","content_hash":null,"metadata":{"rts_finding_id":"rts_finding_982b53c0b7114da5aebaa2bdc840d3e9","epistemic_scope":"dated_publication_official_action_or_historical_incident_disclosure_only","source_bound":1,"evidence_only":1,"no_relation_onset":1,"no_layer_state":1,"no_civilization_snapshot":1,"global_novelty_not_exhaustively_established":1,"original_occurrence_date_preserved":1},"created_at":"2026-11-07T15:26:50.071Z","updated_at":"2026-11-07T15:26:50.071Z"},"sources":[{"id":"src-20261107-rubicon-1","dedupe_key":"36034c376c4e4f621a0c3d35f8e3d33d119477955e60a6c8146afb3a15aecea5","name":"","publisher":"GitHub Engineering","url":"https://github.blog/engineering/architecture-optimization/inside-githubs-new-git-storage-architecture/","evidence_locator":"","source_type":"primary","primary_or_secondary":"","retrieved_at":"2026-11-07T15:22:59.096Z","published_at":"2026-11-05T00:00:00.000Z","author":null,"metadata":{"rts_finding_id":"rts_finding_982b53c0b7114da5aebaa2bdc840d3e9","epistemic_scope":"dated_publication_official_action_or_historical_incident_disclosure_only","source_bound":1,"evidence_only":1,"no_relation_onset":1,"no_layer_state":1,"no_civilization_snapshot":1,"global_novelty_not_exhaustively_established":1,"original_occurrence_date_preserved":1},"created_at":"2026-11-07T15:26:50.064Z","updated_at":"2026-11-07T15:26:50.064Z"}]}
