# Isolated canvas union checkpoint — 2026-09-11
|
|
|
|
Codex-ytr83r; root owns review, publication and native acceptance. Local source `a57c334b302eb13352b4bb65df1c75d94d002348` on `codex/canvas-union-ytr83r-20260911` identifies this source checkpoint and **is not a release**. Main checkpoint `32334c66317692befb6517a917dc7ae90641c11a`, production `865483b4c66361a01fe0d9e731859220bafb4136` and its existing BF9 package remain preserved.

The union selectively integrates 42 source files from peer `a31b40d0f8551ed87c8cd66250b9afb4809b3a79` and its chooser/form/session prerequisites. It retains root B4 lifetimes and marker selection, contextual source/minimum-card corrections and child-work responsibility/history behavior. Header and Create-label clips now apply the same camera pan/scale as their text; pointer inversion remains in canvas-local coordinates. Independent frozen App/prerequisite and renderer reviews found no material integration issue. The [source-review archive](experiments/canvas-union-a57c334-20260911/README.md) preserves exact hashes, primary Iced evidence and the distinction between source review and runtime proof. Its historical “tests pending” text predates the results below.

## Windows gates and new artifact
|
|
|
|
| Gate | Result | Completed UTC |
|
|
| --- | --- | --- |
|
|
| Focused lifecycle | 27 passed, exit 0 | 19:55:46.4531913 |
|
|
| Full desktop all-targets | 752 passed; zero failed/ignored/filtered; exit 0 | 20:06:06.1170595 |
|
|
| Strict desktop all-target Clippy | `-D warnings`, offline/locked, exit 0 | 20:13:49.0390005 |
|
|
| Studio build | offline/locked, unoptimized dev profile, exit 0 | 20:20:48.7677661 |
|

|
|
The focused tests overlap the full suite and are not an additional total. Root ran the test gates; the delegated remaining-gates worker ran Clippy then build sequentially. All **529 inputs / 9,712,849 bytes** matched worktree HEAD and remained unchanged through the gates; final verification was 20:20:58.775988 UTC. Input manifest SHA256: `47FEC9CADC0E7FAE99D789376C111C02EEAAB7FAC3740DE48174A06F61FE16B3`.

The [closed-gate archive](experiments/windows-gates-a57c334-20260911/README.md) carries the terminal logs/statuses, exact gate commands, input checks and artifact provenance separately from the source-only archive. Its original/copy manifests and second readback retain archival verification without claiming another gate execution.

New preserved Studio: **69DBB90FA299B3B3D90140C7934891F79166025893AF9B35B2B8D754A37A0D40**, 113,028,608 bytes. Adjacent libunwind: **AA282FA47BB2C4E210CEA5E470CDBDCA58568F0BE0BC73E404D86AB9CD95EF6A**, 190,464 bytes. Source-before/copy/source-after hashes and lengths matched; both copies were marked read-only. **The matching a57/69DB GUI has not been launched for native acceptance.** Peer 729 and earlier root 707 results keep their original source scope.

## Separate old-GUI native continuation
|
|
|
|
The existing packaged GUI **BF9C2E618D4A4AC55E6A7EBB3738736659FC35A6465522C7B5AB975238938808** belongs to old source 865483b. Its [original OA child-work archive](experiments/native-child-oa-865483b-20260911/README.md) covers first child, sibling and grandchild with exact Save/Undo/Redo comparisons. The [closed continuation archive](experiments/native-child-continuation-865483b-20260911/README.md) adds confirmed OA reopen/Save and SA first/sibling/grandchild, each Undo/Save and Redo/Save, then SA reopen/Save. The [independent review](release-native-child-continuation-review-20260911.md) found no material archive/evidence issue: all 111 original/copied payloads, closed receipts, original identity carriers and nine complete snapshot-directory comparisons matched.
|
|
|
|
That continuation supersedes the former current-state claim that OA remained stopped in an Open dialog and SA was unverified. It does not erase the failed/pending attempts: the first OA `reopened-1948` pair and misleading screenshot filename remain explicitly data-only. Confirmed later screenshots show Source project opened and All source files saved. These receipts establish bounded 865/BF9 behavior; they do not establish a57/69DB native acceptance or explain backend causes of capture failures.

|
|
|
The [old865 typography observations](experiments/lifecycle-header-correction-native-865483b-20260911/README.md) show bounded wide-W/CJK headers in the recorded cases, with exact unchanged source after passive Save. Cluster checks expose scalar shortening that drops an accent or splits a joined emoji; full Unicode presentation is not accepted. Remaining native work includes contextual-source workflows, packaged Home/Guide/normal-close behavior and the new canvas's pan/zoom/clipping, hits, focus and history. The [full user goal](../PROJECT_GOAL.md) also retains broader graphical manipulation, textual engineering, analysis/units, libraries, OA↔SA parity and independent discipline review requirements; this checkpoint is not completion.

Live scope/ownership remains in [issue2](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/2), [issue4](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/4) and [issue5](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/5). Linux setup/build/check activity remains paused by explicit user instruction. This documentation update performs no source integration, compiler/UI action, staging, push or release publication.
