The documentation for the ACL "decode" feature looks like it could do with
improving. In places, it is listed as a modifier; in other places, it is
listed as a condition (but nowhere, AFAICT, does it state what that condition
actually returns).
From a quick glance at the source, it looks like it's actually a condition,
and it fails if decoding is explicitly disabled (e.g. the RHS expands to "0");
defers if, say, the disk filled up; or succeeds if decoding was requested, and
was successful. Does that sound about right?
