mcp.exec.WaitOutcome.PresentAtEntry
-
A wanted pattern was already in the pane's output before this began watching, on a row above the one still being typed into, and is not a line this server itself submitted moments earlier.
Description#
A wait only sees what a pane writes after it starts, so this is never folded into
Self::Matched: the same pattern printed moments earlier -- an earlier command's own output, say -- can already be sitting there, and a caller that treated that as a fresh match would act on something that happened before this call, not because of it. A line this server typed and submitted withsend_keysis discounted rather than reported here or asSelf::Matched, for a short time after it was submitted.
