# Integrated checkpoint — 2026-09-11

Codex-ytr83r, branch `codex/release1-ytr83r`. The full [user goal](../PROJECT_GOAL.md) remains incomplete. Live priorities, ownership and handoffs are in [Gitea issue 1](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/1#issuecomment-410) and [issue 2](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/2). This file scopes integrated code and evidence.

## Verified code and capabilities

Published checkpoint `3ade397008cffe826d5f5a70e7c0233159e3bd42` contains production `29084050a7c020e0fb488be37c6e1ab235769cc0`; push and exact remote readback passed. It combines prior named behavior creation/history integration (`c81e285`, `e207b04`), corrected creation-oracle evidence (`b853a1e`), CLI-only integration (`023e3a8`) and B4 lifecycle rendering.

B4 renders local lifetimes, branch-local activation termination, neutral incomplete lanes, Create capsules and Delete markers with original occurrence identity. Real Windows OA/SA six-case matrices and separate name-only Save/Undo/Redo/reopen workflows passed complete independent Project, reachable-source and physical-file comparisons. These are bounded fixture checks, not complete product usability acceptance.

## Verification scope

On this Windows host, core all-targets passed433 tests with one intentionally ignored scaling probe; that probe separately passed with unoptimized timings. Production29084050 passed focused lifecycle22 and full desktop675 tests (the22 are included in675), and the ordinary GUI build/launch. An equivalent test-helper let-chain correction subsequently passed strict workspace/all-targets Clippy and its focused regression1/1. These results predate the newly identified header-rendering correction.

## Material limitations

Native wide Latin/CJK checks found neutral lifeline header text overflowing its card; Create labels remained contained. Corrected production/native acceptance is not yet established. Combining/emoji native appearance and passive-save equality for the typography variants remain unverified. Current-host server/CLI transport/restart and matching optimized packages are not accepted by the desktop fixture results.

Coherent contextual source/chooser/canvas contributions from other branches require integration and verification here. Calculations, quantities/units, maintained libraries, practical large-model textual workflows, complete OA↔SA engineering parity, documentation and fresh cross-disciplinary review remain full-goal requirements. See the [analysis proposal](release-analysis-semantics-design-20260910.md), [library proposal](release-libraries-semantics-design-20260910.md), [text-authoring design](release-textual-authoring-design-20260911.md) and [decisions](DECISIONS.md) for attributed design evidence, not completed implementation claims.

## Platform and published deliverables

**Linux setup, downloads, builds and checks are paused by explicit user instruction until the user reports networking resolved and instructs resumption.** Ubuntu26.04/WSL2 shell execution was observed; guest networking remained unavailable. Offline preparation was a workaround, not a network fix or Linux acceptance. Host VPN settings were not inspected or changed. [WSL evidence](release-wsl-postboot-ytr83r-20260911.md) and [preserved offline inputs](release-linux-offline-preparation-ytr83r-20260911.md) retain exact outcomes.

Peer Codex-9e8r6t published the separately verified [Windows contextual prerelease](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/releases/tag/v0.2.0-preview.contextual.20260911), source `b2c3e540`; [its publication handoff](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/2#issuecomment-406) binds its artifacts and original-host checks. It is not a B4 release from this branch.

## Record navigation

The [one-time record migration](history/2026-09-11-ytr83r-record-migration/README.md) preserves the exact prior STATE ledger and marks PLAN/TASK_LEDGER superseded. [Earlier integration history](history/2026-09-11-ytr83r-integration/README.md) preserves source-attributed older results. Historical leases, failed approaches and next-step wording do not override current Gitea coordination or the Linux pause.
