+# Initial DF71 native trial
+
+This is failed-trial evidence, not native release acceptance. See the
+[evaluation](../../../release-text-navigation-native-initial-20260911.md) for
+observed passes, four defects, counterevidence, saved-byte comparison and scope.
+
+`manifest.json` describes 52 exact copied payloads; this README and
+`.gitattributes` are explanatory/control files outside that payload list.
+Screenshots are numbered by the actual sequence. Launch, binary readback and
+oracle receipts retain their timestamps and exact commands. The final saved
+checkpoint is `valid-navigation-final-saved`; the earlier similarly named
+checkpoint proves disk equality only. No large executable, private runtime
+profile or credentials are included.

+# Initial native navigation trial — 2026-09-11
+
+Codex-9e8r6t `/root`; [issue 6](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/6).
+**Not accepted for release:** the actual Windows trial found four interaction
+defects. Useful checks below retain their narrower scope. Corrections and a new
+identified native run are required; the published contextual preview is unchanged.
+
+## Identity and isolation
+
+Source is `36db9356cce3c7614ae37eec9fe17678ca210afe`, built from unchanged
+`inputs4`; [build evidence](experiments/text-navigation-native-20260911/build/README.md)
+and [integrated gate report](release-text-navigation-integrated-20260911.md).
+The pinned GUI SHA256 is
+`df7126b8fc14c90985c2a0c55a640990f990e487d95a33f194aa7238754ceabd`
+(113,197,056 bytes). It ran from the private `text-navigation-native-20260911`
+directory, PID 6344, launched at 18:40:00 UTC. Runtime DLL, profile, test copies
+and oracle were pinned by the existing native helper. No WSL, Linux or VPN
+operations occurred.
+
+The earlier shared-desktop queue was based on an unverified assumption. Peer
+filesystem evidence differed; local Computer inventory showed no other Studio.
+[Issue 5 comments 473–478](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/5#issuecomment-473)
+record the correction and peers' independent inventories. Each helper saw only
+its own identified Studio. The trial touched only this returned application.
+
+The app was closed through its title-bar control after the final verified save.
+A fresh Computer inventory no longer contained Studio, and PID 6344 was absent.
+The final binary/DLL readback matched the prelaunch bytes. Stdout/stderr were
+preserved; there was no observed crash.
+
+## Observed behavior
+
+The four-file fixture uses UTF-8, CRLF, Unicode folder `救援`, stable UUIDs,
+one actual `@assess` reference, and five excluded comment/prose occurrences.
+
+| Action | Observed result | Screenshot |
+| --- | --- | --- |
+| F12 inside `links.arcadia`'s authored `@assess` | Opened `救援/assess.arcadia`, selected the alias at line 2, byte column 13 | 02 |
+| Shift+F12 from the declaration | One declaration and one authored use; comments/prose excluded | 03 |
+| Alt+Left | Returned to the originating file/caret | 04 |
+| Insert one comment character | Old rows became disabled and explicitly stale | 05 |
+| F12 in the changed draft | Stayed at origin; offered an explicit draft declaration choice | 06 |
+| Choose draft declaration, Back, Ctrl+Z | Reached the declaration, returned, then restored clean source without Apply | 07 |
+| F12 while Find owns focus | No source navigation | 08 sequence |
+| Minimum window, Find and results together | Actual outer size 1102×732, client 1100×700; source remained editable and tools scrollable | 08 |
+| Escape with Find and results open | Closed both | 09 |
+| Explicit Definition button | Reached and selected the same exact declaration | Native sequence before 10 |
+| Save all after undoing all trial edits | Status read “All source files saved”; full saved oracle passed | 16 |
+
+Navigation and draft choices did not implicitly Apply. Source Undo returned the
+fixture to its accepted baseline. This trial does not prove all focus races,
+ambiguous/missing-include repair, busy cancellation, or the larger engineering
+walkthrough; those remain for the corrected native run.
+
+## Defects and falsification
+
+1. **Diagnostics move the editor during typing.** One comment edit cleared
+   diagnostics immediately and moved the editor top from y518 to y393. Debounced
+   lint restored the rows before the next click, which consequently hit a
+   diagnostic and opened another file. No data was lost. Independent source review
+   confirmed count-dependent diagnostic height plus a max-height-only header.
+   Reserve the existing bounded, scrollable header height; keep stale diagnostics
+   cleared. Verify actual editor geometry remains constant across lint states.
+
+2. **Back reopens an empty panel after Close.** The explicit Definition action,
+   Close, then Back restored the origin but reserved a blank 300 px results column
+   (screenshot 10). Preserve a closed panel on successful Back without a notice;
+   useful refusal/change notices must remain visible.
+
+3. **Find alone needs two Escapes.** With results closed and Find focused, the
+   first Escape merely unfocused the field (screenshot 11); a second closed Find.
+   The captured-input bridge included symbols but omitted Find alone. Add Find
+   to that same bridge while preserving modal priority and route deduplication.
+   Returning focus to the editor must use existing guarded reveal behavior.
+
+4. **System-menu input can alter source later.** A clean focused comment caret,
+   Alt+Space, Escape, then a neutral header click inserted an ordinary space at the
+   original caret. Immediate captures after Escape, including one after a 1 s
+   wait, still looked clean; the next pointer input exposed the edit. The first
+   isolated result therefore appeared to falsify the suspicion (12–13), but the
+   settled sequence showed `is` becoming `i s` (14). A repeat with the caret after
+   `is` produced `is  excluded` after clicking a neutral header (15), without other
+   text entry. Native Size-menu trials had shown the same delayed dirtiness.
+   Exact Windows event payloads were not instrumented. Source review identified
+   Iced's printable Alt+Space fallback as a compatible cause. Test a narrowly
+   scoped Windows binding guard with ordinary Space and international-input
+   controls, then repeat this actual native sequence before claiming resolution.
+
+All these trial edits were undone. Existing clean snapshots and failed states are
+retained. Do not infer a successful action solely from the first captured frame
+after a native modal closes; observe the settled state before a dependent check.
+
+## Saved result and evidence
+
+The final `valid-navigation-final-saved` check ran after the visible successful
+Save all result. The pinned oracle reported exact equality of the complete model,
+identities, all four reachable source texts and all four physical Arcadia files.
+This checks more than selected aliases or reparsing. The earlier
+`valid-navigation-restored` check also compared disk bytes successfully, but it
+preceded a visibly settled successful save and is **not** save-action acceptance.
+
+[Raw trial archive](experiments/text-navigation-native-20260911/initial-trial/manifest.json):
+52 payload files, 1,603,662 bytes, manifest SHA256
+`22eb414ffb45cc68b2f57d9cf516be73c6c52815188839ad32d237eaee69bf0c`.
+It contains the launch and binary receipts, initial source hashes, screenshots
+with capture metadata, both exact source checkpoints, oracle commands/results and
+stdout/stderr. The large executable and private runtime profile are excluded;
+their pinned identity and build provenance remain linked above. Raw files were
+copied with exact byte readback and per-file SHA256s.
+
+Acceptance next: independent review of the bounded corrections; relevant mounted
+geometry/event tests and strict desktop Clippy; a matching preserved GUI; repeat
+the affected native flows, repair fixtures and realistic multi-file walkthrough;
+full saved-source/model comparison; then coordinate a versioned release. Current
+work ownership and timing remain in issue 6 rather than this historical report.
