# Integrated checkpoint — 2026-09-11

Codex-ytr83r, branch `codex/release1-ytr83r`. The full [user goal](../PROJECT_GOAL.md) remains incomplete. Live integration/acceptance work is in [Gitea issue5](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/5); the [project overview](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/1) and [process/scenario requirement](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/2) link other work. This file scopes integrated code and evidence.

## Verified code and capabilities

Earlier 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.

Source `321897fd55af9e07afa2c6ebf1e50be49e86f7d9` integrates the published contextual source-creation/minimum-card corrections from b2c3e540 with B4 and the header clipping correction. Its own Windows desktop all-targets gate passed 704 tests. [Exact selective integration, independent union review and Windows results](release-contextual-integration-update-ytr83r-20260911.md).

Published production `865483b4c66361a01fe0d9e731859220bafb4136` adds the reviewed child-work correction: first refinement transfers existing Allocation and RoleAssignment identities, metadata and artifact references to the child; later siblings inherit only a unique performer. OA/SA regressions cover nested children, roles, folded grouping, unallocated/mixed controls and exact history. The extracted Studio `BF9C2E61…` passed actual OA first-child, sibling and grandchild creation plus Save/Undo/Redo comparisons against original complete model/source checkpoints. Reopening and the SA native counterpart remain unverified.

## 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.

- [Test-only Clippy correction](lifecycle-clippy-correction-ytr83r-20260911.md).
- [Current-host toolchain setup](release-host-bootstrap-ytr83r-20260911.md).
- [Independent Windows gap review](release-windows-gap-review-ytr83r-20260911.md).

The closed 321897f Windows gate passed 704 desktop tests with zero failed/ignored/filtered; all 261 recorded build inputs remained unchanged. Matching server `ABA87A5F…` passed semantic HTTP checks (204 schemas, 19 values, 9 rejected invalid shapes) and the corrected REST probe's 25 requests. [Closed runtime evidence](experiments/windows-runtime-321897f-20260911/README.md) preserves both earlier source-version failures. [Earlier integration checkpoint evidence](experiments/contextual-lifecycle-integration-ytr83r-20260911/README.md) preserves server/CLI 68 across 7 targets, schema 72/204 after the missing-jsonschema correction, and the old GUI's wide-name passive Save comparison.

The later 865483b Windows desktop gate passed **707 tests**, including the three focused child-work regressions, with zero failed/ignored/filtered. All 261 recorded build inputs stayed unchanged. The matching debug GUI build and strict **desktop-only** all-targets Clippy passed; child-work and staged-source checker compilation/admission also passed. [Closed gates and exact inputs](experiments/windows-gates-865483b-20260911/README.md). These checks do not establish the remaining native rendering or packaged acceptance.

The extracted package's unchanged server `ABA87A5F…` passed the actual HTTP schema checks (204/19/9) and 25-request REST editing/persistence/restart probe with a restricted process PATH and unrelated working directory. Seven raw response pairs and exact source snapshots matched; all five test-owned server processes stopped. The first REST run's PowerShell-added PATH directory is preserved as historical evidence; the corrected restricted-PATH rerun is authoritative. [Packaged server evidence](experiments/packaged-server-865483b-20260911/README.md). This completes bounded server runtime acceptance, while the new Windows preview remains unpublished pending the separate GUI checks.

## Material limitations

Native wide Latin/CJK checks found neutral lifeline header text overflowing its card; Create labels remained contained. The [header correction](lifecycle-header-overflow-correction-ytr83r-20260911.md) is included in the tested 865483b source, but matching corrected pixels and combining/emoji native appearance remain unverified. The old GUI's wide-name passive Save pass establishes identity/model/source/file equality, not corrected rendering. Complete combined native and packaged acceptance remain separate. During the OA reopen check, the Computer helper repeatedly failed with `window capture timed out: timed out waiting on channel`; fresh window selection and one clean helper restart did not recover capture. Native input stopped at the Open dialog with the accepted grandchild result already saved. This is a validation-tool failure, not evidence of a model failure or a successful reopen.

Other chooser/canvas and text-navigation contributions still require their own integration and verification. 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.
