+# Navigation and source selection: closed native440 checkpoint
+
+The Windows trial on **44095f78c28b79d6d085863dc928adba8e24d955** closed normally
+with saved source invariants intact. It also found a **P2 Details-to-Preview
+viewport loss**, preserved in frames043–045. That failure remains part of this
+checkpoint. No later scroll correction, final feature acceptance, fresh-package
+acceptance, or release is claimed here.
+
+The [independent final review](review/navigation-native-final-independent-review-20260913.md)
+inspected all24 new frames056–079 in addition to the39 images covered by the
+unchanged [partial review](review/navigation-native-partial-independent-review-20260913.md).
+It checked all14 immutable saved snapshots, complete file inventories and raw
+oracle bindings, then compared all four final work trees after closure with
+their latest snapshots. The two reports distinguish actual images, operator
+notes, source checks, and recorded process observations. They retain their
+original local-only wording; this portable copy makes their evidence reviewable
+once the parent publishes this commit.
+
+## Observed scope
+
+| Workflow | Actual evidence and bounded outcome |
+| --- | --- |
+| Source selection and alias rename | Operational Word/Line replacement and restoration; six-token alias-only preview, Cancel, acceptance, Save, Undo/Redo, and project reopen. Seven saved snapshots equal either the complete baseline or an independently reconstructed six-token expectation. Source↔diagram and chooser/Find dismissal retain the demonstrated target and recover deliberate invalid drafts. |
+| Placement and state row | Compact placement UUID `de1e7e00-0000-4000-8000-000000000029` is hidden, restored, hidden and finally restored while its represented work remains. Five saved snapshots establish the expected two removed states and three exact baselines. Both state-row Delete dialogs name relation UUID ending0036 and are cancelled; actual state-row deletion is not claimed. |
+| Lifecycle integration smoke | OA1 selects the exposed outer activation, inner endpoint, creation capsule and deletion cross as distinct occurrences. SA2 samples Unicode containment and selected outer activation at100% and Fit87%; a tooltip partly obscures the Fit header. SA6 shows unresolved-lifetime cues. The four-file final fixture snapshot is exact baseline. |
+| Repeated/nested topology navigation | The chooser distinguishes OA first/second occurrences; revealing the second selects oa_r2, and Open source/F12/Back reaches its exact occurrence/use/definition identities. SA nested navigation agrees on sa_inner/sa_a across chooser, canvas, tree and Inspector. Both source files remain exact baseline. |
+
+The scroll failure is a same-destination review interruption: after deliberate
+scrolling, Full details→Preview returns to the top while the proposal/file/hunk
+remain unchanged. Separately reviewed correction bebf and subsequent test work
+belong to another source/gate sequence and are not native accepted by this trial.
+Initial Delete after placement navigation was also ineffective until an explicit
+canvas click; that bounded focus friction remains an unresolved usability/policy
+question. Absence of a placement-hide confirmation is intentional, not a defect.
+
+## Provenance and closure
+
+The [launch receipt](raw/trial/launch.json) binds the original staged GUI:
+117,171,712 bytes, SHA256
+`95f0c3e9ea1521dbc555e5330f26e105bd9065b9fb4207980f6d7ae62d2ef99a`.
+The build profile is **unoptimized development**. All72 staged payloads matched
+the original manifest at independent readback. The original successful build
+and its actual Cargo artifact/profile records are referenced from the
+[cccd Windows archive](../navigation-440-windows-20260913/README.md); all615
+recorded source inputs matched440 Git bytes. These build records are reused
+without relabeling their source or duplicating large evidence.
+
+The oracle remains source **e1240295bd114d23d3f67a69e6b38bdb2e25bb0d**, binary
+SHA256 `8937a59a0e1c51619087b43ab059a6e9af3eef9d69dd2735601143ece3452ada`.
+Its exact111 core/config/lock inputs match both e124 and440 Git blobs. The oracle
+compares the complete Project and exact SourceBundle; removal uses core Delete
+and its ordinary source patch, while the six-token source expectation is also
+reconstructed independently from fixed baseline offsets. Expected fixture
+warnings remain in raw stderr; a comparator pass does not mean warning-free
+engineering content. No parser, oracle or GUI was rerun for this archive.
+
+[Closure](raw/trial/closure.json) records owned GUI PID6772 exiting0 at
+**2026-09-13T10:20:14.983254Z**, unchanged stage and empty stdout/stderr.
+The supervisor log contains the same terminal record. The hash-bound launcher
+waits for its child before writing closure; no supervisor failure record was
+present. The parent separately observed terminal94544's exit0 and the missing
+native window; the independent reviewer did not perform a fresh process/UI
+inspection. Normal closure is established by the saved owned-process evidence,
+not inferred from a launch or screenshot.
+
+## Limits and portable verification
+
+This trial does not establish the corrected scroll behavior, automatic keyboard
+focus after chooser navigation, native port targeting, new-file creation, Up
+cycling, every geometry/accessibility/scale state, all lifecycle scenarios,
+general modal/race behavior, optimized performance, Linux, schema8, complete
+OA/SA semantics, or fresh extracted-package GUI/REST acceptance. Historical
+geometry evidence and automated gates retain their own source pins.
+
+The [manifest](manifest.json) preserves exact original bytes for79 notes,78 JPEGs,
+14 checkpoint trees and raw records, baselines/expected fixtures, closure/launch,
+reviews, audit and necessary helper/binding source. Its15 external references
+are pinned to **cccd66c5d522497dbecb28ce722644848943d009** and checked against Git.
+Run the explicit-check, optimization-rejecting [verifier](verify.py) as described
+in the [README](README.md). It checks portable bytes and receipts only; it cannot
+upgrade the known failure or skipped scope into acceptance. Root owns integration
+and publication; no live task ledger or user-owned specification is changed.
