- Unlink the temporary bootstrap launcher binary immediately after opening a read-only descriptor to it, then execute via `/proc/self/fd/<fd>` to ensure zero-disk footprint on execution.
- Unlink temporary `/tmp/resolvconf*` files immediately after successful bind-mounting over `/etc/resolv.conf`.
- Prune parent ephemeral profile directories when unpinning a namespace, leaving zero directories behind once empty.
- Propagate the exact exit status of the wrapped command to the host process using `errors.As` and `*exec.ExitError` instead of defaulting to exit code 1.
- Added E2E automated test `TestExitCodePropagation` to verify exit status delivery.
- Added the `$(BINARY)` target to `.PHONY` in the Makefile to delegate dependency tracking to Go's compiler cache, ensuring modified Go files are rebuilt during `make test`.

- Implement complete rootless network namespace bootstrap via C launcher using unshare(CLONE_NEWUSER | CLONE_NEWNS | CLONE_NEWNET).
- Resolve unprivileged network isolation blackhole via host-socket preservation (FD passing): open client UDP sockets on the host pre-isolation, clear O_CLOEXEC, and ingest them via custom `FDBind` inside the sandbox.
- Implement isolated routing table automation over `tun0` (addresses, MTU, default routes).
- Implement persistent, multi-process namespace sharing and joining using reference-counted PID files and the setns system call.
- Write robust, self-contained E2E data plane test suites in `tests/e2e/e2e_test.go` using a mock UDP listener.
- Update project documentation (`README.md` and `AGENTS.md`) to reflect completed milestones.
- Ensure 100% test passing rate and zero lint/staticcheck warnings.
