The term “post-exposure” refers on this website to any time after the exposure is ended.
TCQ’s definition of “post-exposure” (“anytime after the exposure is ended”) matters because the end of the recording process marks an important transition point in the making of a TCQ photograph.
When it comes to non-“light”-related aspects of photographs, TCQ makes a strong distinction between visual effects determined by things that occur before the exposure is ended vs. visual effects determined by things that occur after the exposure is ended.
The background brief on “before vs. after”
It’s either “pre-shutter” or “post-exposure”
There is by definition no interval of time between the end of the “pre-shutter” period and the beginning of the “post-exposure” period.
Everything that affects a photograph happens during one of those two periods.
On this website the term “post-exposure changes” covers anything done to the photograph after the exposure is ended.
That is true regardless of whether those actions occur in the picture-taking device, on a computer, in a darkroom, or by any other means, and it is true regardless of whether the changes are done intentionally or by accident.
In some contexts, post-exposure changes are commonly referred to simply as “post” (e.g., “I’ll fix that problem in post”).
However, because some photographers do not like the shorter term (and because it may be confusing to non-English speakers), the longer phrases “post-exposure changes” or “post-exposure processing” are preferred on this website.

The list of TCQ’s Allowable Changes section details all of the changes that can be made to TCQ photographs after they are recorded.
