When an EC volume's .vif was missing, NewEcVolume wrote a stub holding
only the version. That stub implies the default 10+4 ratio with
DatFileSize=0 and no encode identity, which the custom-ratio resolver
and the startup credibility checks then read as an authoritative config
-- masking the real ratio of a custom-ratio volume and defeating the
byte-exact .vif gate. Mount with in-memory defaults instead and leave
the real .vif to the encoder or a recovery tool. The Rust volume server
already behaves this way.
