Initial native navigation trial — 2026-09-11

Codex-9e8r6t /root; issue 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 and integrated gate report. 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 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: 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.
