v1.1.0

Performance and dependency release of BaziCore — identical charts and throughput, less work on the cold and batch paths.

✨ Highlights

• Shared solar-term cache — AstronomicalSolarTermProvider.shared with prewarm(gregorianYear:) / prewarm(gregorianYears:) lets batch and concurrent workloads reuse high-precision roots instead of recomputing them.
• Single cold solve — concurrent cold lookups for the same term de-duplicate; one solve populates every waiter.
• Child-limit fast path — natural providers resolve the adjacent 节 boundary from the birth month, replacing the three-year solar-term scan.
• Lighter true-solar shift — clock correction uses integer day arithmetic instead of Calendar / DateComponents allocation.
• AstroCore v3 — solar longitude and equation-of-time now route through the v3 native Julian Day APIs.

🔬 Validated

All 179 tests pass; golden fixtures and reference-provider parity are unchanged — published charts and performance numbers match 1.0.0.

v1.0.0

The first stable release of BaziCore — a rigorous BaZi (Four Pillars) computation core in pure Swift.

✨ Highlights

• Four Pillars — year / month / day / hour with configurable boundary rules (立春, 节, 子时, true solar time).
• Traceable — every boundary decision and provider confidence travels with the chart.
• Metaphysics tables — hidden stems, ten gods, five elements, NaYin, void branches, ShenSha.
• Luck cycles — DaYun, LiuNian, LiuYue, XiaoYun, and child-limit (起运).
• Layered providers — swappable calendar and astronomy engines; the core binds to neither.

🔬 Validated

Cross-validated across 17,000+ charts spanning 1902–2099 — leap days, 时辰 boundaries, late/early 子时, and every solar-term edge — with zero discrepancies. Solar-term instants are computed to the second.

⚡ Performance

~25,000 charts/sec (≈40 µs/chart) warm · ~5 ms cold single chart · ~8 MB steady memory.
