- listChildren contains per-child projection faults on both ladder rungs (any registered unit's fold/schema rejection maps to that child's corrupt diagnostic) and pins the whole-enumeration listing-failure rethrow - the base bundle mounts session-projection (web-app's own insert retired to avoid the double mount); stale composition comment updated - the shared projections-unavailable wire face is pinned across list/history/prompt; retired session-query arms removed from the catalog paths - the design note records the unknown-parent semantics shift and the fold-fault isolation rule
