Ownership
Own meaningful stakes and record them: an ownership claim carries an instrument, a percentage and a date, or it is not a claim.
Ownership is a record before it is a philosophy. A claim carries an instrument, a percentage and a date, or it does not enter the register — and the register is kept by the parent rather than by the property, because a property is not the authority for how much of itself somebody else owns.
Control and ownership are held apart on purpose. The directory format publishes a control edge stating which organisation answers for another with no quantum disclosed, precisely so a structure can be published by a group that will never publish a cap table. Minority positions are ordinary here; what is not ordinary is a claim about one that cannot be grounded.
Ownership is also plural where the facts are plural. A company incubated at the canonical incubator and formed alongside a vertical’s own arm is held by both, and publishing a single owner to keep a diagram tidy would put a false structural claim into the one record whose entire value is being trusted about exactly this.
And it is answerable. Every property names one accountable human, which is a rule of the standard this group publishes rather than a courtesy: an organisation that cannot name who answers for it does not launch.
What it refuses
An ownership claim without an instrument, a percentage and a date. A position that cannot state all three is not recorded at all rather than recorded loosely, and no quantum is published where the office holds a stake it has not been given permission to disclose.
Where it is practised
The estate register is maintained by the parent, and a position that cannot state those three things is not recorded at all.
