`switch.sh --list` showed every slug regardless of topology, so a single-GPU box listed dual/multi configs it can't actually run — noise. Filter `--list` to the topologies the detected GPU count supports: 1 GPU -> single only, 2 -> single+dual, 4+ -> everything. Detection reuses switch_topology_from_gpus (CUDA/NVIDIA_VISIBLE_DEVICES, then nvidia-smi) mapped to a topology rank. - `--all` (and the `--list-all` alias) bypass the filter for discoverability; --list is deferred until args are parsed so `--list --all` works in either order. - Don't silently hide: print a one-line note naming the detected GPU count and exactly which topologies were hidden, plus a `(+N … hidden — --all)` tally in the header. No note under --all / when nothing is hidden. - Fail-open: with no detection signal (no selector, no nvidia-smi) show ALL — never hide off a guessed "single" fallback. - Counts (header + per-model) reflect the visible set; PR-A health markers/grouping and PR-B Defaults view unchanged. New test scripts/tests/test-list-topology-filter.sh covers 1/2-GPU filtering, --all, --list-all, order independence, the --all-without-list guard, and fail-open.
