5 new unit tests in filter::table::tests: - drop_rule_actually_drops (R33 bug regression test) - accept_rule_actually_accepts (R33 bug regression test) - rule_matching_other_hook_does_not_apply (hook isolation) - default_policy_applied_when_no_rules (fallback) - reset_counters_clears_metrics_keeps_rules (R34 method coverage) All 5 tests pass — proves the critical verdict bug from R33 is fixed and reset_counters from R34 works correctly. Also adds FilterTable::chain_summary() returning: 'input: pkts=12 bytes=5678 policy=ACCEPT' (per-chain line) for use by future netcfg summary extension.
