When the basis of an action is withdrawn
A requirement is amended, a grant is revoked, a fact goes stale. Which dependent actions are refused before their effect, which become findings after it, and what do simpler checks already cover?
Where this stands
What the evidence shows 1
- On constructed cells, an argument bound to a value derived from a declared source was refused when the true basis moved, passed when an input moved without changing the derived value, and was refused when the agent's number differed from it. CAU-02 re-checked.
What remains open 3
- Under today's default, where the budget is the agent's judgement, the action executed when the basis moved and when the source disappeared; citing the source for reread refused lawful work where the derived value had not changed. CAU-02 re-checked.
- Today's at-most comparison refused a raised ceiling and a lowered one that still held the value. The derived binding is parked because no shipped declaration has a pure ceiling, and it makes the deriver a new trusted party. CAU-02 re-checked.
- Reread reaches 20 of 64 reference slots in the 20 shipped declarations and is off by default there; 16 slots reach objects only through paged lists. Of 21 judgement slots, 3 rest on read content the guard cannot see. FRS-08 re-checked.

30 of the 32 studies in this direction are not yet published, mostly because they ran on stands whose source material cannot be published; a few also rest on records not yet in the repository.

Derived values in a guard declaration: judged, cited and derived arms on constructed cells
A derived binding refused when the true basis moved and passed when an input moved without changing the output, while citing the source refused both; today's at-most comparison refuses a raised ceiling.
Does it work? Guard study
How far an action-time reread reaches in the shipped declarations
20 of 64 reference slots in 20 shipped declarations have a reread road; 3 of 21 judgement slots rest on read content the guard cannot see. Reread is off by default in shipped declarations.
