Target previously-uncovered functions in the path/file-operation files the
resolver restructure touches, confirmed hit under coverage:
preallocate --preallocate (syscall.c do_fallocate) and sparse hole-punching
via --preallocate --sparse and --inplace --sparse (do_punch_hole),
on a file several levels deep.
fuzzy-basis --fuzzy basis selection with similar-named candidates and no
exact match, so the generator scores them (util1.c fuzzy_distance).
delete-deep add a --backup --delete case so removing an extraneous
backup-suffixed file consults delete.c is_backup_file.
preallocate probes --preallocate support up front and skips where it is
unavailable: macOS, the *BSDs and Solaris build without fallocate/posix_fallocate
(and FALLOC_FL_PUNCH_HOLE is Linux-only), and reject the option outright. It runs
on Linux and Cygwin. fuzzy-basis and delete-deep are plain local transfers with
no skips. All green on master and under --protocol=29/30.

Cover the structure and link options at >=3 levels and across directories,
asserting each option's specific effect:
links -l keeps a symlink, -L dereferences it, -k follows a
directory symlink -- all on a symlink several levels deep.
dirs -d copies the top layer (file + empty dir) without recursing.
prune-empty-dirs -m drops empty chains and chains emptied by an exclude,
keeps populated ones.
hardlinks-deep -H preserves a hard link whose names live in different
directories at depth; without -H they become separate inodes.
delete-deep --delete removes a deep extraneous file/subtree; the four
delete-timing variants agree; --max-delete caps deletions;
--existing / --ignore-existing select/skip correctly.
relative-implied -R mirrors an implied directory's mode at depth;
--no-implied-dirs does not (proto 30+).
Green on master and under --protocol=29/30 (the --no-implied-dirs sub-case is
gated to protocol >= 30, where multi-component sender paths are accepted).
