Read the sources.
Keep their clocks.

The reference footer says S01–S24, but the page contains 26 entries. Its Bitcoin treasury heading says twenty, while the table contains 21 rows. Its Litecoin product universe has 20 rows and its corporate Litecoin table has 11; we do not add invented entries to reach 21.

The notes below reproduce the reference’s stated timing and limits. They do not certify those figures. One source was a private prior report; its private link is not repeated here. The published PDF preserves the review context. Current guide sources and accepted daily observations are identified separately.
