UTFANSWF v23 integrated reproducibility validation environment
Initial integrated validation checkpoint: August 19, 2026
Final production verification date: August 30, 2026

Reference validation environment:
- Python 3.13.5
- numpy 2.3.5
- scipy 1.17.0
- pandas 2.2.3
- PyYAML 6.0.3
- mpmath 1.3.0 bundled locally

Canonical command:
  python -m harness.run_all_gates

The command executes:
- 18 canonical UTFANSWF gates
- Frog 8/8 research-overlay integrity check
- authoritative Aug. 19 new-prediction reproduction suite

Final production verification:
- Row 26 bundle-provenance / manuscript-PDF decoupling checks PASS; both main.tex and main.pdf are excluded from live executable acceptance
- prior Windows local canonical run PASS on August 24, 2026
- amended-bundle canonical rerun PASS on August 25, 2026 in the reference validation environment
- final manuscript/bundle release-layer synchronization completed August 30, 2026; current bundled manuscript companions are not live hash identities
- final canonical rerun PASS on August 30, 2026 after manuscript-companion/documentation synchronization
- 20/20 ledger entries PASS
- overall blocking verdict PASS

PASS under encoded gates is a reproducibility/integrity result, not independent scientific validation.
