HALTSEAL RC8.0.1 — historical public summary Public summary revision 2 / October 1, 2026 Source release: August 25, 2026 Source archive SHA-256: b86d43315c932e30054e7bb6a10c12ae4e25b5b18ff47af7bd1c86330ccc00dd Recorded scope: local, synthetic release validation. Local integrity, deterministic packaging, regression and synthetic control checks were reported as passing. No new canonical control semantics were introduced by this release. The synthetic replacement remained held while the original outcome was unresolved. Closure evidence restored eligibility without creating release authority. A fresh request was evaluated separately, and replay added no effect. These findings do not establish independent reproduction, actual buyer coverage, native-provider behavior, production reliability or commercial value. They do not validate later engine releases. No reliability percentage is claimed. Detailed validation records and reproduction materials are available by request: scott@haltseal.com. Current scope and evidence: https://haltseal.com/proof/
