Which model each app runs today, and when it last changed

Which entries never mention the version before

Three entries promote a numbered house generation and say nothing about the versions it replaced. A number tells every reader that lower numbers existed, so each of these pages raises a question it does not answer, and a production already working on an earlier line cannot plan from anything public. As of 2026-09-12.

Where a numbered generation is promoted with no mention of its predecessors. Recorded 2026-09-12.

Inclusion rule. An entry appears when its own public page promotes a numbered generation and does not address earlier ones. A version reachable behind a login does not fill a cell. Order. By entry name, with the summary row last.

1A blank beside a number is a sharper blank

Most empty cells in this register record an unasked question. These record a page passing over an obvious chance to answer one, because numbering is itself a claim that a sequence exists.

The register keeps that distinction because it changes what a reader can do. A blank with no context is a question; a blank beside a version number is a question with a reason to ask it.

2Silence is not removal

Assuming the earlier lines are gone would be as unfounded as assuming they remain, and the two assumptions lead to different plans. The register records what the page says and nothing more.

What a production can act on is narrow: record the version behind each delivered file while a page still names it, because no page here will confirm afterwards what was available when.

3One entry in this table is quiet for a different reason

A single house model with no version numbering raises no question about predecessors, because nothing implies a sequence. That is a thinner page and a cleaner one.

It also means a version change there would leave no trace at all, which the default reading for that entry sets out.
