The workspace had no single verification entrypoint, so every claim of
'green' rested on an ad-hoc command chosen after the fact. ./check makes it
one command, mirroring the convention already used by the original build.
./check fmt + tests + clippy -D warnings
./check quick tests only
./check mount the above + live FUSE end-to-end (root, 27 assertions)
The FUSE adapter compiles in every stage (--features cubefs/mount) so the
kernel-facing code can never silently rot behind a feature flag. The live
mount stage is opt-in because it needs root, /dev/fuse and attr — but it is
the only stage that exercises the real kernel VFS path, and it encodes the
two Package 3 regressions (mkdir -p to depth 4, cross-user ACLs) that every
unit test missed.
Adopting clippy -D warnings immediately paid for itself: it failed on two
pre-existing Package 1 defects that per-crate greps had let through —
a needless_range_loop in TriEnc::unpack_6 and a doc comment orphaned by a
blank line in HeaderFlags. Both fixed.
Verified: ./check green; ./check mount green (27/27, no leftover mounts).
