+## Mounted State picker correction
+
+The combined Windows test run at `8ddfadf440b5c208b1adb6b211a97ba0c99cff04`
+failed the mounted State missing-picker Escape regression. The test located the
+picker relative to the canvas, but the integrated selection toolbar adds 56px

+Parent and independent source inspection agreed on this fixture defect; they
+found no reason to change the production Escape policy from this failure.
+
+Successor `a9cd364eacbbffa0693bab05b5a2b65f9d105535` adds a zero-padding
+identified container around the existing fixed-height picker slot. The fixture
+measures that slot, checks Escape capture before App subscriptions, and retains
+zero messages, exact document/source/selection/camera/revision/history,
+reopen-and-Place, and exact source Undo checks. The option coordinate assumes

 ## Combined gates and package handoff
 
+The first peer compilation exposed E0425 in the new Route fixture: its
+`project_view` call lacked the `projection::` qualification used by the parent
+helpers. Combined successor `4deced53b98cd4d7649ba7aa60fa4b9b30d2f3b8`
+cherry-picks peer `e68a83959900e556768d8470640e28a7df7d8cb8` to correct that
+single test line. Production code is unchanged. This concrete finding supersedes
+the earlier `9e99618c` build handoff; the failed compile ran no tests and remains
+part of the peer's evidence. Source review and formatting did not catch it.
+
+The first combined Windows attempt on `897d9f04` then found E0433 in the
+Allocation Text Apply test added at `542b10ac`: the test's module lacked
+`iced::widget::text_editor`. The current successor incorporates peer
+`7c2b06b63f8a0fe14b3f001996bdf965b36a4e85`, adding that import only. Production
+code remains unchanged. The failed combined compile ran no tests, lint or
+product build; its 3,709 source inputs stayed unchanged and formatting passed.

 The 21-line early guards precede pending-reveal reconciliation, allocation_before, inner dispatch and post-dispatch reconciliation. The preceding preview/selection-boundary computations are reads. Connection Endpoint/Restart require both current route Context and extant matching session; Choose/Begin retain their intentional new-owner behavior. Current Restart remains admitted and creates a fresh Choose session. Route Commit/CommitAttachment require current Context and payload edge equal to current selected edge, without incorrectly demanding a Connection session or armed attachment.
