Both current catalog contracts were inspected before execution. The artifacts
were non-empty, decodable and non-truncated under machine checks. The prior
human selection of one voice on Eleven v3 remains recorded in
[the 2026-08-01 verification](2026-08-01-verification.md).

## Honest boundary

The current environment could not perform a semantic listen or transcription,
so this rehearsal does not replace the existing human judgement or extend its
review date. Publication must pause after 2026-09-01 unless a human listen-check
confirms the sample or a new full rehearsal supersedes it.
