The #211 admission batch traded 133 corpus fixes for 6 explained regressions (known_below_threshold.txt 195 -> 68). Each of the 6 is root-caused by the per-arm A/B and needs its own lever — none is fixable by gate tuning (all gate shapes were measured, see #211):
config/yaml/yaml_003_logging_config, config/yaml/yaml_012_queue_config, infrastructure/terraform/terraform_070_coalesce_function — the greedy itself admits naming-reachable junk while the gold file's channel is weaker: recall 0 with forbidden hits present, so the zero-context rescue escape never triggers. Lever: relevance ranking (why junk outranks gold at equal reachability), not admission.infrastructure/kubernetes/kubernetes_001_selector_edge_pulls_workload — no edge channel carries the k8s selector -> workload relation at all (rel=0, so even an ungated rescue cannot pick it). Lever: a dedicated kubernetes selector edge in config_edges/kubernetes.rs.synthetic/balanced/suite-2/one-hop/bal2_1hop_064_csharp_dto_mapping_bugfix, bal2_1hop_067_csharp_entity_config_change — gold context reachable only via lexical similarity; every declared-relation gate shape blocks it, and their selections carry some context so the zero-context escape does not apply. Lever: a dedicated dotnet channel for the missing relation, or a measured similarity escape.
Close condition: each case either leaves the baseline via its named lever, or its lever is measured and rejected with data.
