-Class assignment must be deterministic. For strict parity with bash v1, peer IP strings must be sorted lexicographically, exactly like `sort -u` in the old script, then assigned `class_start_id + index`. Do not silently switch this to numeric IPv4 sorting in v1: the production snapshot maps `10.8.1.10` before `10.8.1.2` because bash sorted text, not numeric addresses.

 `docker exec` should not be the architectural default. It can remain as compatibility fallback if `nsenter`/host tools are unavailable, but the design assumption is that the Rust binary has host authority and controls the relevant namespace.
