+## Isolated post-reboot machine reopen
+
+After the user resumed, root copied only the immutable first machine checkpoint
+into a fresh `contextual-source-20260911-reopen2/work` and used a fresh profile.
+The unchanged GUI52DE82 and F456 runtime hashes were checked before launch.
+The preceding `reopen` attempt reached only the Open picker before another
+user reboot and supplies no acceptance. Latest actual Windows boot was
+13:59:33.500 UTC; the successful new app PID was5804.
+
+The real Open picker loaded the isolated project. Selecting SA displayed the
+saved machine and first state view, owner and earlier Function/Chain. Ctrl+S
+reported all source files saved. The unchanged independent evaluator passed
+the complete Machine prediction using the original first Lifeline/Chain/Machine
+role carriers, followed by exact same-model/identity/six reachable and physical
+file comparison with the original machine checkpoint. There were zero retained
+detached files in this complete accepted state. This is persistence across a
+fresh process/profile after reboot, not a Redo or a corrected-layout pass.
+
+The file picker returned a16×16 auxiliary screenshot before its actual1108×633
+dialog capture. The first coordinate input was refused outside those auxiliary
+bounds; no model mutation resulted. An attempted UIA value operation was also
+unsupported. A fresh capture and the actual large screenshot then allowed
+ordinary filename click/type/Open. Both tool failures precede the successful
+native path and do not change the oracle expectations.
+
+Raw launch records, screenshot, full/same oracle logs and result are in
+`.local/native-qa/contextual-source-20260911-reopen2`; the six saved source bytes
+are identical to the already archived first machine payloads.
+Exact preserved output and source mapping are now in
+[postboot reopen evidence](experiments/contextual-source-reopen-20260911/README.md).
+The app closed normally and refreshed window inventory confirmed its absence.
