G-102 record: composite scrubbed run verified at 4d9c8a26; echo finding recorded

The archived verification is corrected to the accurate history: the earlier
scrubbed passes proved each pipeline step green individually while the
single-invocation composite was failing on the decorative echo banner steps
(a pipeline-exit misread had over-claimed it). With the banners removed the
clean-clone composite now runs to a true exit 0 with all four shells landing
(incl tclsh90szip/tclsh90sprzip) and every smoke green; the echo-spawn hazard
joins the environment findings. The sprzip install residual is marked resolved
(user application released the file; copy completed).
