# Studio Readiness Gate — Public Verification Record

**Verification date:** August 25, 2026  
**Version:** `studio-baseline-gate-v1`  
**Disposition:** VERIFIED PUBLIC CANDIDATE / NOT PUBLISHED

## Reproduction result

- Automated tests: 6/6 passed.
- Frozen acceptance behaviors represented: incomplete block, complete synthetic review state, invalid dimension block, unknown-provenance block, unavailable-measurement limitation, and deterministic output/input preservation.
- Sanitized incomplete fixture: `BLOCKED`, 27 issues, fabrication authorization false.
- Complete synthetic fixture: `READY_FOR_HUMAN_REVIEW`, zero issues, one retained measurement limitation, fabrication authorization false.
- Two consecutive executions produced byte-identical result files.
- Input fixture hashes remained unchanged.
- The implementation imports only Python standard-library modules and contains no model or network operation.

## Privacy and provenance review

The selected public package files were scanned for machine-local paths, private URLs, contact details, network addresses, authorization headers, and common credential markers. No matches were found. The incomplete public fixture declares itself a fictional sanitized structural derivative; the complete fixture declares itself synthetic.

The internal source manifest, original known-state fixture/result, private project sources, photographs, measurements, plan materials, and identifying client/location data are not included in `PUBLIC_SHA256SUMS.txt` and are not authorized for public distribution.

## Demonstrated

- Missing values and unsupported provenance remain visible rather than being inferred.
- Every issue is reported in stable order.
- Honest measurement unavailability can remain a limitation without fabricating data.
- Passing the deterministic gate reaches human review only.
- Fabrication authorization remains false on every generated result.

## Not demonstrated

No acoustic design, treatment quantity, cut list, placement, simulated performance, construction, outcome, savings, adoption, or business return is demonstrated. The tool is a readiness validator, not a design authority.
