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

The fields every entry in this register carries

A field page covers one column of this register: what has to be published before a value goes in, which entries currently carry one, and what an empty cell means. As of 2026-09-12.

The fields every entry is read forEach entry in this register is read with the same short list of questions, and each question became a column. The pages in this section take one column each and say what fills it, what does not, and how a blank should be read.What every entry is read forNamed replacementDoes the notice that ends a model say what followsStored workWhat becomes of material kept inside the productNotice periodHow much warning is owed before the engine changesDefault tierWhich model runs when nobody touches the selectorFour questions, asked the same way each time
Fig. 1 A column exists here only where vendors sometimes publish into it, which is why the list is this short.

Every entry is read with the same questions. Does the notice that ends a model say what follows it. What happens to the material kept inside the product. How much warning is owed before the engine changes. Which model runs when nobody touches the selector.

Those questions became columns, the columns acquired names, and the names started turning up in the first cell of tables across the site with nowhere to point at. These pages are where they point. Each one says what fills a cell, what does not, and how the blanks should be read.

The list is deliberately short. A register that tracks what vendors publish can only carry columns vendors publish into, and adding a column for what a reader wishes were published is how a record of statements quietly becomes a record of guesses.

1The fields

  • Named replacement — A retirement notice can name the model that takes over.
  • Stored work — A model ending also ends the place its output was kept.
  • Notice period — No application here publishes how much warning arrives before its model changes.
  • Default tier — Whatever an untouched project runs on is where most delivered work comes from.
  • Lifecycle states — Three hosting platforms publish the states a model can sit in before it goes.
  • Ending early — A published date is one of several ways access ends.

A field earns a page once its name is already doing work in the first column of a table somewhere in this register.

Other notices: Apps, Models, Side by side, Questions, Terms, Learn, Data. Where each line comes from is set out on the sourcing page.
