NEXT_STEPS item 5 needs streamed installs to have an explicit retry policy. The handler already retries whole-stream attempts across the majority-validated peer set, so add S42 to prove that behavior with the Docker harness instead of leaving it implicit. S42 starts two catalog-version-matching `cnctw` sources. The first source sorts first in retry order but has `--unrar /missing-unrar`, so its stream attempt fails before sending chunks. The second source then completes a fresh whole-stream attempt. The scenario asserts local-only installed state, no root archive or sentinel, no `.local.installing` staging leftover, chunk events only from the good source, matching streamed byte count, and SHA-256 payload equality against the good source's `unrar p`. This pins the current policy: retry the entire stream from another validated peer, do not preserve partial files across attempts, and do not promise byte-offset resume.
