# Verified branch checkpoint — 2026-09-24 UTC

This describes Codex-956atf's contribution, not a combined release.
[PROJECT_GOAL.md](../PROJECT_GOAL.md) remains authoritative. The complete OA/SA
application is unfinished; published previews and finite prototypes are intermediate.

**The current prerelease is Windows-only. Linux/WSL builds and checks remain
excluded by the user's explicit request, including after networking recovers.**

The separately assembled Windows source is
**715036e132677dd2bc2fb37ed316d93dc9987aec** on
`codex/prerelease-integrated-956atf-20260924`. Its
[source handoff](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/src/commit/715036e132677dd2bc2fb37ed316d93dc9987aec/harness/prerelease-integrated-source-20260924.md)
identifies the integrated contributions, reviewed event correction and exact
test paths. Combined runtime/package acceptance is separate from the
contribution-specific evidence below. [Issue37](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/37)
owns current build and release coordination.
The Route helper qualification and Allocation Text Apply test import corrections
are included; both earlier compile failures occurred before tests ran. The candidate's 66 package
documents/examples pass [closure and source-identity verification](reviews/prerelease37-windows-documents-20260924.md).
The separate e68a839 Route contribution's raw test/lint evidence passed an
[independent evidence review](reviews/prerelease37-route-evidence-20260924.md);
its results do not establish combined-candidate execution.
The full Windows test run at `8ddfadf4` failed a State picker fixture whose
canvas-relative coordinates hit the added selection toolbar. The current
source includes peer `a9cd364e`'s measured picker slot and capture assertion;
the [independent source review](reviews/prerelease37-state-picker-20260924.md)
retains its bounded assumptions. [Reviewed targeted evidence](reviews/prerelease37-state-picker-evidence-20260924.md)
at `a9cd364e` passes formatting and all26 State tests, including the original
failure. The corrected combined [test-evidence review](reviews/prerelease37-final04-tests-20260924.md)
at `715036e` verifies 2,200 passed, eight ignored and zero failed across all
2,208 names in 61 native harnesses, including all 29 required cases. The
[complete gate review](reviews/prerelease37-final04-complete-20260924.md) verifies
all 3,709 inputs against immutable Git bytes, strict workspace Clippy and the
individual Studio/server builds. The supplemental combined build also passes;
its differing artifacts are not the selected package inputs. Packaged acceptance
remains separate.

## Current integrated candidate and evidence

Branch `codex/behavior-authoring-20260910`, published as `codex/release1-956atf`.
Integrated code checkpoint **4ffff0d9d94bd1875e6b316b84ac11e5c5c9657c** combines
the reviewed ordinary/Text contribution **3f9e6a18af96b5cd10940da4093be8da28b9c835**
with source-editor Tab/Shift+Tab indentation. Windows desktop verification passes
1,188 tests with six existing ignores; all 1,194 names and nine targeted
indentation cases are accounted for. Strict desktop Clippy and matching GUI
build pass on 711 unchanged inputs. The closed native trials cover caret and
forward/reverse block indentation, text undo/redo, empty drafts, continued caret
typing and Apply/Save/reopen. The saved 577 bytes exactly preserve the baseline's
mixed line endings and Unicode while indenting its 13 physical lines. The first
trial restored the baseline and is not a save oracle. Find's Tab does not advance
focus; this inherited limitation is distinct from the verified editor boundary.
This is Windows contribution acceptance, not complete editor accessibility,
public source8, a combined peer union, or a packaged release.
[Exact gates, original native captures and independent review](experiments/text-indentation-4ffff0d-20260923/README.md)
retain both the failed initial compilation and the interrupted first trial.

Earlier code checkpoint **8abc144cf233c64e43c6bee5033c22ee818e2d14** preserves
the production inputs of **feab2020d8e5b6bfdb59c86ab4aee161617b8b6f**. Its Windows
desktop suite passes 1,096 tests with three existing manual ignores; all 1,099
names are admitted. Targeted navigation/rename checks, strict desktop Clippy and
the matching development GUI build pass. The closed native trial verifies
Details-to-Preview scroll restoration, explicit reset boundaries, and exact
six-file preservation after Cancel and Save. The
[portable evidence](experiments/rename-scroll-feab202-20260913/README.md), published
at **f95d0310482565e91220a97e13fc756f27f9d590**, retains the initial failing test,
20 original frames and independent review. Its committed bytes and verifier were
rechecked on September 22. This narrow trial does not establish Text integration,
complete rename acceptance or release readiness.

Earlier production source follows; each result retains its original code scope.
Verified production source **44095f78c28b79d6d085863dc928adba8e24d955** includes
Find focus, departure-selection and scoped Escape corrections. Its Windows
desktop suite passes1095 with3 existing manual ignores; core passes471 with1
manual ignore; server passes56. All three strict Clippy scopes and the matching
development GUI/server build pass. [Exact source, commands and raw evidence](release-navigation-440-windows-20260913.md).
The integrated documentation checkpoint **3c22fe2629fc242714d32805790262fa2c4e33b9**
preserves those production inputs and includes the updated AGENTS instructions.

The actual440 native trial closed normally with79 notes,78 images and14 complete
saved-model/source comparisons. Rename/Undo/Redo/reopen, scoped selection,
placement/state targeting and sampled OA/SA lifecycle/topology navigation are
verified within the [closed trial's explicit scope](experiments/navigation-native-440-20260913/REPORT.md).
It found a same-page Details-to-Preview scroll-loss defect; initial keyboard
Delete after chooser navigation also required an explicit canvas click. Neither
is hidden by passing saved-byte checks. The scroll defect is corrected and
verified by the separate feab trial above; the initial chooser-to-canvas keyboard
focus friction remains a limitation of the 440 trial. This remains a development
checkpoint, not a combined release. [Integration issue27](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/27)
owns current verification, correction and release coordination.
Earlier source **e1240295bd114d23d3f67a69e6b38bdb2e25bb0d** combines the canvas
contribution with source/diagram navigation and reviewed alias rename. Its1082-test
listing,17 cross-feature tests,4 mounted preview-scroll tests and strict all-target
Clippy pass on578 unchanged inputs. Combined full-suite, GUI/native and package
acceptance are not established. [Exact partial evidence](release-navigation-palette-e124029-windows-20260913.md).
The matching core comparator and migrated fixtures pass their bounded preparation
checks, including an independently specified six-token rename. The original
migration-evaluator failure and its correction are preserved in
[preparation evidence](release-navigation-native-preparation-20260913.md); these
results do not establish GUI editing or save/reopen acceptance.

Earlier source **e44f07565cc7599d5c5a15a6b5599b4f5d105718** combines direct process/scenario
authoring, allocation interaction, focused deletion and Save/Undo focus fixes,
typed nested activations with lifecycle clipping, and stronger palette roles.
Its custom menu/chooser target cues pass 12 and 14 actual-renderer tests, and
the complete Windows desktop suite passes all 874 tests on 538 unchanged inputs.
Strict Clippy exposed two test-only pixel-iterator lints, corrected by subsequent
source **dd39e1fdc13f04f18975a70736d2ed7f752a6df2** after the required array-reference
coercion correction. All ten affected style tests, strict Clippy and the matching
GUI build pass at dd39. Its bounded native trial closes normally with 41 frames
and five complete Project/exact SourceBundle comparisons: lifecycle rendering,
selection, custom overlay cues, architecture/state boundaries and process previews
pass within the stated scope. [Native evidence and limitations](release-canvas-native-dd39e1f-20260913.md).
Earlier native results retain their exact source scope.

- **d61f1f3**: all 836 Windows desktop tests, strict all-target Clippy and matching
  GUI build pass on 533 unchanged inputs. Its bounded native trial passes nested
  activation border continuity, exposed-shoulder versus exact-message selection
  in bound OA/SA and reentrant scenes, minimum-window Fit, and exact saved
  Project/SourceBundle preservation. [Native evidence and independent review](release-canvas-native-d61f1f3-20260912.md).
- **aadc639**: reviewed lifecycle/typed-activation integration passes 36 lifecycle,
  14 activation and one atomic Call/Reply tests on 536 unchanged inputs. The six-
  scenario native fixture additionally passes actual-core admission, exact source
  and canonical whole-Project round trips, ordering, values and operation bindings.
  These are targeted/core results; desktop native acceptance is separate.
  [Integration and fixture evidence](release-lifecycle-activation-union-20260913.md).
- **afa74a3**: all ten targeted palette tests pass on 538 unchanged inputs,
  including actual WGPU selection/copy across an enabled-to-read-only field
  rebuild. Essential canvas and process boundaries, Source selections and resolved
  control colors are covered within the report's stated scope. Later a357b22 adds
  custom-overlay cues; its new paint tests exposed a missing test lifecycle step.
  Test-only e44f075 initializes the real overlay layout before drawing; corrected
  rendered tests and its 874-test full suite pass as recorded above.
  [Palette decisions, reviews, exact results and limitations](release-palette-readability-20260913.md).

Earlier accepted focus, architecture/state deletion, Inspector text protection,
bound scenario Save/reopen and discovered paint defects retain their exact
[83f53c7 native evidence](release-canvas-native-83f53c7-20260912.md).
[Canvas follow-up evidence](release-canvas-followup-20260912.md) links the original
failures and corrections. Earlier authoring and allocation checkpoints remain in
[canvas authoring evidence](release-behavior-canvas-a31b40d-native-20260911.md) and
[allocation interaction decisions](release-allocation-feedback-decision-20260912.md).

## Isolated contributions and material limitations

Combined peer candidate **e34ba27e26ede3ab55f276acc250d92b2e0c3204**, published on
`codex/peer-union-956atf-20260923`, composes current Text/Tab with saved Scenario,
final inspector actions, attachments, State bends and the transition footer.
The literal Windows workspace suite passes 2,005 tests with zero failures and
eight named ignores; all 2,013 listed names across 60 executables and three
doctest sections are accounted for. Strict workspace/all-target Clippy and the
matching native/external-oracle builds pass on 760 unchanged inputs. The
[portable gate evidence](experiments/peer-union-e34-windows-20260923/README.md)
binds three rebuilt executables through fresh listings and preserves the failed
historical f82 desktop run (1,337 passed, three failed, seven ignored), the
missing-DLL listing attempt, and capture limitations. Its verifier passes the
positive case and rejects all 12 semantic mutations. The preceding
[partial gate archive](experiments/peer-union-windows-20260923/README.md) retains
earlier Scenario and lint failures. The separate
[native checkpoint](experiments/peer-union-e34-native-20260924/README.md) records
33 successful whole-model/source checkpoints, the retained failed G2 pointer
attempt and its recovery, and five transition checks through fresh reopen and
unchanged reapply. The first trace identity and all resulting source-bundle bytes
remain exact. Independent review checks 245 frame pins and inspects 38 keyframes;
17 transition-oracle controls meet their expected outcomes. The original
interrupted process and later normal-close observations remain distinct. Dirty
middle-button pan, held-drag Escape and short-window Scenario Apply are unobserved.
Public format and release acceptance remain incomplete; accepted root production
remains4ffff0d. The newer prerelease candidate and live coordination are in
[issue37](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/37).

Analysis/core source checkpoint **a2a28f8d23a46ba1696b6a8410d4d3b5c1808f49**,
publication branch `codex/analysis-core-956atf-20260911`, is not integrated into
production. Its private staged typed parser/lowerer has142 listed tests,
34 passing typed cases,1 passing raw-token case and strict all-target core Clippy
on531 unchanged inputs. The complete library run remains126 passed/16 failed,
with all16 failures at the unsupported public source8 header. The original
fixture error and its test-only correction remain in [exact S2b evidence](release-analysis-source-s2b-20260913.md).
Published private writer **f1d79df4979121335ed7b4ce4da84b2fca8a9ef4** has
[portable S2c evidence](experiments/analysis-source-s2c-windows-20260913/README.md):
152 listed, 44 typed and one token test passed, strict Clippy passed; the full
library result remains 136 passed / 16 failed at unsupported public source8.
Published source **1b1c3e3abb6fc3d0934c9dbfbd21fddc8ae4f594** adds a private
qualified source index/rename plan and the independently reviewed cleanup for
the demonstrated depth129 rejected-tree stack overflow. Its
[S3 evidence](experiments/analysis-source-s3-windows-20260922/README.md), published
at **345a42e4658f6e0e8e01ef64a2df8f4e28a8945a**, records 167 listed tests,
59 typed passes (nine index/five update), one token pass, three clean stack
controls and strict Clippy on 538 unchanged inputs. The original overflow and
dirty diagnostic/probe results are retained. No current full-core pass is
claimed. Public source8 parser, writer, source-update and persistence composition
remain incomplete; these branches are not integrated production analysis.

Published private source **10d7f3340d5cd61a656dc0bcf7c143f8897c5551** adds
complete borrowed original-span export for later edit composition. Its
[Windows evidence](experiments/analysis-original-span-20260923/README.md) records
173 listed tests (all prior 167 retained), 65 typed passes including all 11
updater cases, and strict core all-target Clippy on the same 538 committed
inputs. Review caught and corrected an intermediate standalone budget
regression. This is an isolated export adapter; the later syntax checkpoint
below supplies mixed-bundle ownership, while output compilation and public
source8 remain incomplete.

Published private mixed-syntax source
**a578ac98a06772a60bec00ae287e65650680d119** retains the complete source bundle,
original positions and exact caller policy, using shared ordinary/typed token
consumption with explicit identities and aggregate file/byte admission. Its
[Windows evidence](experiments/analysis-mixed-syntax-20260923/README.md) records
194 listed tests, all prior 173 retained, 20 focused mixed passes and 85 typed
passes within the actual full result: **178 passed / 16 failed**. All 152
historical statuses are unchanged and all 42 later tests pass. Strict core
all-target Clippy passes on 541 unchanged committed inputs. Formatting remains
failed in six inherited, unchanged files. Original failed gates and the host
clock discontinuity are retained; a fresh actual direct listing binds the final
focused/full executable after Cargo rebuilt it. This syntax witness does not
resolve or admit a complete mixed Project, activate public source8 or implement
editing composition. The accepted
[complete-Project contract](analysis-mixed-project-contract-20260923.md) defines
the semantic boundary implemented by the separate private checkpoint below.

Published private complete-Project source
**aaec78fcc9b273d1485497126392afdd1fb2e54e** retains the original syntax, bundle,
budgets and limits while resolving/admitting the complete ordinary/typed model.
The next [mixed typed-index contract](analysis-mixed-index-contract-20260924.md)
is accepted after source review and resolved accounting/completeness findings.
Private typed-index source **93eb6117f95353d25d594d59780018f197c51672** implements
the consumed witness and shared verifier. Its
[Windows evidence and independent oracle review](experiments/analysis-mixed-index-20260924/README.md)
verify strict core Clippy, all seven new cases and the complete 216-name inventory
on 545 unchanged inputs. Full library remains **200 passed / 16 failed**,
preserving all 209 baseline statuses; formatting still has the identical eight
inherited blocks. Original lint and depth-expectation test failures are preserved.
The [source review](analysis-mixed-index-20260924/source-review.md) records three
repaired diagnostic findings; its reviewed production hashes are unchanged.
The new owner keeps legacy updater authority separate. Ordinary occurrence
indexing, complete mixed editing and public source8 remain required.
The [ordinary occurrence successor contract](analysis-ordinary-index-contract-20260924.md)
uses retained parser positions and physical token keys, with a separate consumed
read-only owner; it is an accepted design, not an implemented capability.
The preceding Project [Windows evidence](experiments/analysis-mixed-project-20260924/README.md)
distinguishes runtime source **71cadfa0cd0e112caa29588d2494753301f3cb6c** from
the formatting-only aaec successor. Strict core all-target Clippy, actual listing
209, Project 13/13, shared validation 2/2 and four exact public compatibility
cases pass on 544 unchanged inputs. Full lib remains **193 passed / 16 failed**,
preserving all prior statuses and exact unsupported-public-source8 diagnostics.
Successor formatting remains failed on eight inherited blocks in five unchanged
files; no aaec runtime rerun is claimed. The parent-reviewed portable verifier
and all 15 finite controls pass, with independent raw-output/pin readback.
This private source is not integrated into the application prerelease. Public
source8, complete mixed indexing/edit composition, checked output and UI parity remain
unfinished.

The [reviewed S1/S7 assessment](issue28-s1-s7-assessment-956atf-20260923.md)
distinguishes static analysis/case overlays from contextual inheritance,
fixed/default bindings and executable trade studies with durable result
provenance. Strengthened fixture and parity criteria remain proposals, not
implemented evaluation or a replacement metamodel decision.
Earlier [S2a evidence](release-analysis-source-s2a-20260913.md) retains its
129-test113/16 library result and separate7/9 language integration result,
including the old V2 oracle that omitted the empty definitions catalog.
[Earlier bridge evidence](release-analysis-source3-bridge-20260913.md) remains scoped
to6216cff.
The earlier2c515cf full library run had98 passes and16 failures:14 rejected the
unsupported source8 header and2 exposed the now-corrected legacy bridge mismatch.
Its original failed suite and naming lint remain in
[historical evidence](release-analysis-source-s0-s1-20260913.md). No current full-suite
or complete bundle migration acceptance is established.
Its design and source reviews are preserved in that branch's
`harness/analysis-source8-20260913/`. Public source8 support remains incomplete.
At its earlier **847b1caa7e75bb82f6ce5193c45bcfc45973ad1a** base, Windows checks
pass the128 KiB-thread lifecycle subprocess, six codec tests,
28 analysis tests, 26 numeric tests and strict all-target core Clippy. The driver
is included in the six; these counts are separate scopes.
`DEPTH_128_VALIDATED` remains false. Its existing public checked-save regression
now fails: saved source declares schema8, which the parser rejects. All 512 inputs
remained unchanged; the JSON iteration did not run. [Failure and repair boundary](release-analysis-checked-save-20260913.md).
Legacy/migration integration, optimized resource measurements and complete
source8/transport/evaluator acceptance remain open.
[Exact codec evidence](release-analysis-codec-windows-gate-20260911.md).

Complete direct manipulation and persistent process placement/lanes, coherent
peer navigation/source integration, quantities/calculations/constraints,
maintained libraries, graphical/source/REST parity, transitions, ergonomic
engineering workflows, aligned reST/help, optimized packages and final independent
acceptance remain required. Palette arithmetic does not establish every monitor's
appearance; thin overview geometry, syntax scanability, focus, custom overlay
appearance and routing-warning discoverability retain their explicit limitations.
Gitea owns live priorities, ownership, dependencies and handoffs.
