1 Scope
Complete baseline ephemeris evaluation of legacy engine.
2 Audited artifact
@quizzman/qm-calendar v1.0.0-legacy
3 Environment
Node.js 18.x
4 Method
Cross-comparison against Hong Kong Observatory and USNO tables.
5 Reference datasets
- HKO Historical Tables (1901-2050)
6 Test coverage
85% baseline coverage.
7 Findings
The computational audit evaluated boundary conditions and confirmed resolutions for the following defect items:
| Code | Item | Severity | Status | Resolution |
|---|---|---|---|---|
| DISC-01 | Detected 9 systematic deviations | Critical | Superseded | Identified defects categorized as A01–A09, superseded by AUD-CAL-2026-003. |
8 Deviations
Found divergences on golden date 01/09/2026 and historical timezone conversions.
9 Reproducibility
Historical baseline archived in test suite.
10 Conclusion
Legacy engine required systematic overhaul; led to specification QP-CAL-001.
