Coverage, including the gaps.

2024–2025 and 2027–2028 remain unloaded. Stock Connect is excluded. SGX/CME/ICE need product-specific calendars. Source checking does not confer human verification or rights approval.

Traceable sources. Honest review dates.

DCE/CZCE use complete secondary reproductions cross-checked against two annual copies and all holiday night notices; official originals remain pending. Discovery links alone are not evidence. Human and rights approvals remain pending.
