This desk follows companies reporting LTC, their original filings and the share basis behind per-share calculations. A shorter verified list is more informative than an invented twenty-company league table.
The notebook / 01
One historical checkpoint is not a live register
Each filing belongs to a reporting date. If a press release arrives later, show both dates. A ratio computed from a historical holding and share count stays attached to that same checkpoint; today’s share price does not refresh the numerator.

Separate the claims
Maintain a record for issuer-reported holdings, a record for tracker attribution and a record for our own calculation. The calculation should expose units and rounding. Missing dilution or ownership information remains a limitation, not a reason to fill a cell with a guess.
