A PTC dispatch block retains its event's `parentCallId`; a root Session call has no such field, so descendants route through the same keyed dispatch — a registered view such as `read_image` renders its card there, and unregistered descendants keep the generic flattened form. Path summaries relativize to the Session cwd first, then replace a leftover POSIX Host home with `~`; `filePath` and Host open prefer the operation-time absolute result path while displayed labels keep the authored argument. Successful older root results retain their argument fallback; pending relative paths wait for a result. The registration receives the normal Session slot runtime share but no React node or Runtime service.
