Release Notes

Container::check_payload_readable, which says whether this build can
decode the payload before anything is extracted. Container could already
state the payload's name and size without touching its bytes, and nothing
said whether those bytes were reachable: a caller found out by attempting the
extraction. That is the wrong shape for anything that commits to an operation
before performing it, such as a window putting an Open button on a payload
card.

It refuses with the same three Unsupported variants Container::payload
does, in the order that function meets them, so the two never name different
reasons for one refusal. Both facts come from the central directory entry
read when the container was opened, so it borrows shared, decompresses
nothing, and reads nothing further.

Ok says the decoder exists rather than that extraction will succeed:
truncated data, a failed checksum, and an i/o error are still ahead. And it
is a capability query rather than a verdict — SPEC 2.5 puts compression and
encryption outside the conformance question, so a container whose payload is
encrypted is conformant and its payload is out of reach, and validate goes
on saying the first of those.
