Replace the shell-script-based logmockzfs wrapper with a Go-native multi-personality binary (busybox-style). The platformtest binary now acts as a safety interposer for zfs/zpool when invoked via symlinks, validating that all commands reference the hardcoded test pool before delegating through sudo. Key changes: - New interposer.go: SetupInterposerPath creates a tmpdir with symlinks and replaces PATH; RunInterposer validates args and delegates via sudo - Pool name, image path, and mountpoint are now hardcoded constants - Remove ZpoolCreateArgs, Zpool struct, and CLI flags for pool config - Remove logmockzfs/ shell scripts (logzfsenv, zfs wrapper) - Simplify Makefile: no more logmockzfs invocation or root check - Add -no-interposer flag for direct execution as root - Safety: block -a (all) flags without pool reference, validate mountpoint paths against traversal, command-aware flag parsing Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
