# Postboot machine reopen — 2026-09-11

Real native Open picker, SA machine view and Save in a fresh profile using the
unchanged GUI52DE82 passed the complete independent Machine oracle and exact
same-model/identity/six-source physical comparison. This closes isolated machine
reopen, not the missing Machine Redo or newer layout acceptance.

`manifest.json` binds nine original payloads, copied byte-for-byte. It maps the
six saved source files to identical already-committed payloads in
`../contextual-source-native-20260911/source-bytes/`, preserving normal relative
filenames without duplicating bytes. Every saved file matched that archive.
Manifest SHA256: `f79c13083762c64ed17c06eb46f614bdb9fa11589107d48f841aa6b3c921e39b`.

`interrupted-first-launch.json` is the earlier attempt that reached the file
picker before the next reboot; it has no acceptance claim. The successful run's
launch record, separate logs, result and screenshot are named plainly. The root
native report records the auxiliary16×16 screenshot and unsupported UIA-value
operation failures before successful ordinary click/type/Open.

The unchanged oracle source/fixture and original Lifeline/Chain/Machine role
carriers are already committed. The checker calls were:

```
staged-source-authoring-contract check machine BASE REOPEN FIRST_LIFELINE FIRST_CHAIN FIRST_MACHINE
staged-source-authoring-contract same FIRST_MACHINE REOPEN
```

Runtime PATH was scoped to verified GUI52's bin and Windows directories. No
observed source was used as its own expected identity authority. Both exits were0.
