Replication package for the manuscript "A Deterministic Acceptance Boundary for LLM-Assisted Multilingual Web Production: An Engineering-Research Case Study," submitted to Empirical Software Engineering. The package contains the primary machine evidence (Level A), derived datasets (Level B), study materials, and manuscript source for an embedded single-case study of a deployed multilingual static web-production chain in which human edits and LLM-assisted proposals traverse the same deterministic acceptance gates. The studied release is website version V296 (deployed 18 June 2026); the legacy-to-static cutover occurred 11 June 2026. Included are the 16-sub-event V296 deployment decomposition, an incident register coded by gate family, a claim-support matrix mapping each headline claim to its supporting evidence and stated limitation, a 40-period cutover-aware Chrome User Experience Report (CrUX) classification, the archived schema.org vocabulary used for build-time semantic validation (with SHA-256 pin), minification-equivalence reports, the full deployment transcript, and a SHA-256 manifest of the entire package. A redaction policy (REDACTION.md) documents removal of security-sensitive and identifying information; no quantitative result is affected by redaction.
