The closest text I found so far is from

IEEE Std 1003.1™-2024
XCU
1.4 Utility Description Defaults
CONSEQUENCES OF ERRORS

79953  • When an unrecoverable error condition is encountered, the utility shall exit with
79954  an exit status that indicates an error occurred.

79955  • A diagnostic message shall be written to standard error whenever an error
79956  condition occurs.

(the numbers are the total line numbers from the pdf instance of the standard).
