# Progress Ledger — first release

## Active continuation — 2026-09-10

Latest checkpoint: read updated objective attachment `578cf63e-08b7-411f-a01e-20416441d5e2`
fully and updated `PROJECT_GOAL.md`. Its emphasis on Capella-level useful modeling
and usability keeps behavior authoring central. Packaging is committed `b98f135`;
current product/release acceptance remains incomplete. First merged desktop
artifact finished **615/618 passed**, with three concrete failures assigned;
the previous running status below is historical. Full evidence and diagnosis:
`release-integrated-gates-20260910.md`.

Current leases: behavior_audit owns scenario workspace/B3 corrections and sole
Cargo compilation; release_audit now owns only new behavior/creation.rs/tests
pending coordinated shared wiring, with packaging frozen; palette_finish owns
exclusive native input for a bounded Capella behavior-creation study. Root does
not operate native UI until that lease returns. Candidate 2 closed cleanly after
F2 equality and saved Actor checkpoint; no process 648 remains. Root owns merges,
specification checks and ledgers. Other host owns remaining typed-history seed
fix, standalone scenario lifetimes and its own native scenario contract.

Integration update (2026-09-10): local branch is `codex/release1-9e8r6t`.
Palette `7d1df4f` is published separately. Received Codex-956atf's exact Git
bundle (57,658 bytes, SHA256 `85A38B00207036DCB8DB24ED4A7E80B2BE670275EEB7B00413D36153322ADA5D`),
verified its parent `1797516`, and published its original `01bb52a` commit on
`codex/behavior-authoring-20260910`. It is being merged here with our palette
fixes and all additional tests. Only common ledgers conflicted; the other host's
dated sections are preserved in `release-otherhost-checkpoint-20260910.md` so
its cold toolchain/process claims cannot be mistaken for this host's state.
Its optional history-value constructor cache defect has a follow-up pending.
No integrated compile/native pass is claimed. Scenario layout follows the merge;
the checkpoint worker independently restores inline name focus after recovery.
The user subsequently reauthorized Computer Use explicitly. Candidate 2 native
F2/Save/Undo/Redo now passes the independent exact name-only three-source delta
and the full Entity Undo oracle. Recovery autofocus is committed in `31b7dc3`;
its 13 focused tests passed after integrated compilation. The immutable 618-test
artifact from `057eddd` plus that checkpoint patch is running separately from
current source edits. The verified follow-up bundle `b6b76ef` now supplies the
F1 nullable-constructor correction; its additional tests await the next build.

Latest checkpoint (18:10 UTC, Codex-9e8r6t): palette compile repairs, bounded
inline naming, stale-submit retention and focused first-Escape cancellation are
implemented. Candidate 1 passed desktop 588/588; candidate 2 passed 22 focused
tests, GUI build, format and strict desktop Clippy. Candidate 2 native recovery,
focused Escape, first-submit Save As and complete Entity model/three exact
sources passed. Full basic editing/transition/reopen acceptance remains pending.
The user stopped Computer Use with physical Escape; native control is paused.
Source integration and packaging continue. See `release-palette-native-20260910.md`.

Two independent hosts cooperate in Gitea issue #1: this host is Codex-9e8r6t;
Codex-956atf owns process insertion, scenario clicked slots/reuse navigation and
typed stored-history forms. Exchange separate branches from `1797516`; do not
overwrite the shared continuation ref. Our later scenario layout work awaits
that source snapshot. Our release worker owns packaging/Docker/notice scripts;
our behavior worker independently reviews those changes. Cargo writers remain
serialized. Linux runtime is blocked by a verified supported WSL2 import failure
(`HCS_E_HYPERV_NOT_INSTALLED`); no repeated workaround is authorized by that fact.
The user has been asked for a viable Linux environment. This does not block the
remaining Windows/product work. The release is not accepted.

The renewed user objective is recorded in `PROJECT_GOAL.md` and attachment
`d3ddacce-6cca-47c5-9dd4-3d7cc2cfdba1/pasted-text.txt`. Continue to a complete,
usable OA/SA first release; the release is **not accepted**. Initial HEAD is
`1797516`, branch `codex/release1-continuation`, initially clean working tree.
Gitea issue #1, its comments and Wiki Home were read before resuming work.

The current user request authorizes native Computer Use verification. Older
Escape-hold statements below are historical. No Arcadia, Capella, Cargo, rustc
or QEMU process was running at this continuation's initial inventory. Root owns
native Windows operation, integration and the common ledgers. Current workers:

- `palette_finish`: architecture palette/inline naming repairs and the sole
  initial Cargo writer lease; focused tests and a GUI build for native QA.
- `behavior_audit`: independent actual behavior/scenario workflow and semantic
  gap review, with no GUI control or implementation changes.
- `release_audit`: fresh requirements, platform and release gate review;
  read-only Linux readiness inspection, no VM launches or system changes.

Highest-value next actions: repair and verify the unfinished palette, exercise
real basic diagram editing against the existing independent fixture, act on
concrete behavior-workflow findings, then close current platform and release
acceptance gates. Historical Linux boot-workaround rejection remains recorded;
do not retry the denied action. Historical test counts do not establish current
acceptance. Meaningful progress is underway through repairs, independent review
and preparation of native model/source/history checks.

The sections below retain their original evidence scope and date.

**Checkpoint publication — 2026-09-10:** the user requested committing all current changes and pushing `codex/release1-continuation` to both `origin` and `gitea`. This is a work-in-progress snapshot. The interrupted palette-focused compilation failed with E0659 (ambiguous `column!` in `app/architecture_authoring/palette.rs:168`) and E0507 (moving the view out of an Arc in `diagram.rs:624`); an unnecessary-pattern-parentheses warning also remains in `architecture_authoring.rs:346`. The prior 584-test pass does not cover this newer palette revision. No Cargo/rustc process or local subagent was active at the publication preflight. Fix these errors and complete automated/native acceptance before packaging the redesign. Gitea coordination starts at issue #1 and the project Wiki; older evidence below retains its original scope.

**Latest priority checkpoint — Capella consultation and redesign:** the user rejected the large creation buttons and explicitly requested consulting the installed Capella. Native control resumed for that consultation in a disposable Capella 7.1 workspace. Actual palette, F2 rename and activity allocation were exercised; saved XML confirms allocation distinct from ownership. The horizontal creation/connection rows are being replaced with a compact expandable palette and inline naming. This supersedes the Escape hold and toolbar-fix proposal below. New implementation, native acceptance and a fresh user build remain pending. [Observed benchmark, alternatives and acceptance criteria](release-capella-basic-editing-20260907.md). The first-release goal remains active.

**Latest checkpoint:** basic-editing v1 passed full desktop584/584, Windows binaries, format and strict all-target Clippy. Native v1 D8CFAA confirmed direct contextual named Entity creation at100%, and found a22px placement shift caused by the pending toolbar changing canvas height. The user pressed Escape at the attempted Undo; that action did not execute. **Desktop control is paused again.** Process9600 remains the isolated unsaved QA application; do not overwrite its binary or presume a clean close. Code-only placement fix is continuing. [Exact v1 evidence and remaining acceptance](release-basic-editing-reset-20260907.md). This supersedes the resumed-control state below; the first-release goal remains incomplete.

**Superseding priority checkpoint:** the user explicitly said “Resume desktop checks” and rejected the focus on advanced review before basic diagram editing. Isolated native checks resumed and reproduced the global creation catalog, placeholder creation/camera jump and noisy review. Contextual named creation and compatible layer-transition destinations are now being implemented and tested. Their new executable has not yet been accepted. [Current priority and scoped evidence](release-basic-editing-reset-20260907.md). The older Escape hold and next-step priorities below are superseded; historical binary/test results retain their original scope.

Current checkpoint: 2026-09-07. The requested Windows development preview is built and packaged with its runtime, documentation, notices and complete examples. Latest Fit6, two existing scroll/branch regressions, full desktop570/570, workspace bins, formatting and strict workspace/all-target Clippy pass. Corrected server56/56 retains its earlier unchanged-server scope. Packaged DC50 GUI launched and the OA graph Fit overview was observed at1444×932 and1102×932; minimum-height and pending-form native acceptance remain open. The user stopped Computer Use with Escape; do not resume native control without renewed authorization. Native Linux core436passed/2ignored remains verified; corrected Linux server and full Linux GUI build/runtime remain open. The fresh Linux desktop cross-build passed on Rust1.90 in2m20s using the preserved cache; ELF and all37 teaching files are verified. Three later guest boots failed the early IO-APIC timer check before SSH/tests; the exact-kernel workaround was then rejected by automatic approval review before launch. All task VM processes are stopped. **Goal active; release incomplete.** The authoritative objective is `C:\Users\User\.codex\attachments\10b0f701-1743-4de7-9ee1-225920e19649\goal-objective.md`: a usable, feature-complete OA/SA engineering tool for Windows and Linux with graphical/source/REST parity, artifact traceability, offline guidance and independent end-state acceptance.

## Workspace and ownership

- Current branch `codex/release1-continuation`, checkpoint **4b6b5fc1977523e8cf52fdd5503a0a71c87a3f63** commits290files of source6 work and evidence. [Bounded checkpoint audit](release-checkpoint-integration-review-20260906.md) verified65pinned manifest entries and145exact staged/working fixture/archive files; `.gitattributes` protects their measured line endings. Integrated ancestry starts at `c091f80`; [branch audit](release-branch-integration-20260906.md) prevents reimplementing already integrated work. New source7 implementation is authorized but not yet accepted.
- Historical6BAB native scope (superseded in rendering by BCC1 and Fit by DC50): acceptance binary `.local/native-qa/bin-source7-acceptance/arcadia-studio.exe` SHA256 `6BAB6CDE7D31326F3C3CF7342D9B25FB6ADA032864BBE8104625E5EC9736283B` follows the Windows433/55/561 and strict/build gates below. Reset and ReadStatus each passed exact complete model/source Save/Undo/Redo and reopening with the correct derived Reply allocation30/31. OA caller→First.B passed exact persistence/history/reopen; routing remains open. Process11060 closed cleanly; isolated old6 recovery process11240 also closed after its complete source/JSON/raw-draft pass. Old5 process5244 subsequently passed exact30-source/full-JSON recovery and raw-workspace comparison. Current7 process8224→10420 passed invalid nested-link draft crash recovery; completing the recovered SA X→[R3,Inner]/B link passed exact model/two-source Save/Undo/Redo and saved reopening. Those historical native processes closed; the later BCC1 routing and DC50 Fit evidence is recorded separately below. [Native evidence](release-source7-native-acceptance-20260907.md).
- Completed bounded90minute Linux gate: one-job Rust1.90,455-file immutable snapshot SHA256 `7104946c89b2be7a1a030fdff47cb4405bacf05357d68cf35d181e860f55c279`, launched07:02:43UTC, deadline08:32:43UTC. Server compilation passed17m10s; unit2/2 and HTTP50/51 passed, with one504-vs-412 test assertion reproduced in an isolated rerun. Its two-second read/PATCH checks passed, but later persisted-state assertions were not reached. This establishes a timing-dependent fixture/deadline mismatch, not a production locking defect. Native core completed436passed/0failed/2ignored across40targets, Rust1.90, compile23m03 and1992seconds total; all455 source pre/post checks passed. The two ignored cases are optional inheritance scaling and explicit strace fault injection (earlier separately scoped injection passes remain historical). All artifacts were copied before sync/poweroff; QEMU6280, launcher5000 and seed816 were absent08:13:56UTC. [Current Linux report](release-source7-linux-gate-20260907.md). Earlier Linux evidence retains its older snapshot scope. WSL remains pending restart; no host restart is authorized.
- Windows session5735 completed all six gates with exit0: focused prepared-HTTP and cancellation, full server56/56 in68.78s, format10.44s, strict workspace/all-target Clippy99.60s, bins102.22s. Status/logs: `.local/source7-post-routing-gates-status.json`. Distinct GUI BCC1FC6DB68123C9D3A43CE53AA8EF59E33C54080632C104C99ED13270D5333F process8568 passed the scoped corrected routing checks and closed cleanly. [HTTP evaluator correction](release-http-preparation-phase-regression-20260907.md), [routing correction](release-contextual-route-native-fix-20260907.md), [native details](release-source7-native-acceptance-20260907.md). These passes precede the now-tested [Fit/layout correction](release-process-fit-layout-audit-20260907.md).
- The requested Windows preview is `dist/ArcadiaStudio-preview-source7-20260907-x86_64-pc-windows-gnullvm/arcadia-studio.exe`; its565-file ZIP includes all37 teaching-folder files and has SHA256 `1fac10b30daf2f8e1dac29e9469485e4bea142e77ff5a13e4c9d1e41ff03abb2`. The adjacent provenance records actual source/binary hashes. This is a development profile, not an optimized final release. Latest gates are in `.local/source7-latest-preview-status.json`; full desktop570/570 completed in198.82s test time,200.63s command time, exit0 in `.local/source7-latest-full-desktop-status.json`. Initial Fit4/2 failures exposed real zero-size-slot remounting; corrected constructors pass unchanged expectations. [Fit review](release-process-fit-independent-review-20260907.md), [development summary](../DEVELOPMENT_SUMMARY.md).
- Computer Use is stopped. Read-only inspection initially found preview9148 and second GUI8044 live; later9148 exited without agent intervention, while8044 remained untouched. No GUI control/closure is authorized for background verification. The cross-compiler lease ended after the successful142.766s monotonic run; no cross processes remain. The Linux worker completed a bounded headless guest experiment and released the lease. Three boots (same configuration twice, then Normal boot priority) reached terminal IO-APIC timer panic before SSH/Cargo; all task VM trees stopped and exact evidence was preserved. Exact matching kernel/microcode extraction passed without changing base/overlay hashes; automatic approval review rejected preparation/launch of the transient no_timer_check experiment as “blocked by policy.” No fourth boot or corrected tests ran. No task VM is live; see [the preserved boot evidence](release-source7-linux-server-corrected-gate-20260907.md). [Cross-build report](release-source7-linux-gui-cross-build-20260907.md).

## Current source build and stopped runtime gate

The guide-only followup compiled successfully with locked Windows workspace bins in12.70s Cargo/12.82s command, exit0. Status `.local/source7-guide-current-build-status.json` records guide SHA256 `80A6797051FB28E767F2AB5DD2F335ABCD9F3E5F3A75C731CDE46D8B90D5C92E`; resulting GUI SHA256 `327FBDF734716A7F1AF2874183D46A531A8F429BA1A478E83A3E7F2EB1D6248B`. Formatting and independent actual-label review pass. This later debug artifact does not replace the user-facing packaged DC50 preview, its archive or earlier native evidence. No full570 rerun is claimed for the text-only followup.

Previous goal turn made progress by confirming full570 tests and handing off the package/summary. This continuation produced the successful Linux GUI build/ELF evidence, validated purpose oracles, corrected/built guide text, and concrete guest-boot evidence. Goal remains active/incomplete. The denied direct-boot action must not be split or retried to bypass automatic review; no new Linux job is running or scheduled.

## Latest Linux build and purpose-oracle evidence

Linux GUI snapshot458files `source7-20260907T102528493108Z` has archive SHA256 `9b10aa8457a5371367f7e24a0b2260b63c19fed69873d98a3972062a744503d7`. Run `20260907T1025486926611Z` passed locked/offline Rust1.90 zigbuild, both source checks and independent ELF/package readback. GUI72,953,296bytes SHA256 `330A3872D48EBF24AD21E6D4FA13CB6098BEBB3CB7FF82A2E082925CCF3DD346`; ELF64PIE, glibc requirements≤2.28, all37 lesson files exact. Actual Linux GUI runtime is still unverified. Subsequent guide-label text is excluded from both published Windows and this frozen Linux preview.

Extended native checker `source7-native-contract-incidence.exe` SHA256 `16994DC437F5CCC5E5F6FBB4212C03449F2389AE4615FA98B2930B3637468EE3` compiled with warnings denied in4.05s during a coordinated short lease. OA Exchange and SA CommonWork self-checks pass: exact contextual assembly, unchanged precedence, wrong direction/work rejection, caller-only exchange coverage and stable source update. Separate43-element/10-relation incidence fixture baseline passes; all original golden hashes and preserved OA-link/Reset accepted cases remain exact. Independent review found no material issue. [Cases and reproducible native steps](fixtures/source7-native/README.md). Native purpose authoring/history remains pending.

## Completed and verified at this checkpoint

| Scope | Evidence and limit |
|---|---|
| Historical source6 diagnostics and guide | Semantic filter **108 desktop + 2 core** passed; full desktop **527/527** passed; strict all-target Clippy and GUI/server build passed (`.local/semantic-diagnostics-final-tests.log`, `desktop-diagnostics-final-tests.log`, `diagnostics-final-clippy.log`, `diagnostics-final-build.log`). Subsequent guide **3/3** focused tests, strict Clippy and build passed (`.local/guide-navigation-{tests,clippy,build}.log`). The guide test increases compiled desktop inventory to528; no full528 run or final full-workspace total is claimed. |
| Current artifact implementation checkpoint | Full desktop **518/518**, corrected fresh artifact picker **6/6**, strict all-target Clippy passed. Logs `.local/source6-artifact-inspector-desktop-tests2.log`, `.local/source6-artifacts-final-tests2.log`, `.local/source6-artifacts-final-clippy3.log`. Four subsequent artifact recovery falsifiers and two core absence oracles passed separately. This predates latest display corrections. |
| Native artifact MOVE / CREATE / DELETE | All three complete source Apply/Save, one Undo/Save and one Redo/Save oracles passed; **nine saves succeeded first attempt**. MOVE invalid Owner and disabled optional text, and CREATE excluded row/all eight decisions/reserved UUID survived controlled-stop recovery exactly. DELETE removed destination from identified moved-source absence while retaining the source link. [Exact native report](release-artifacts-native-20260906.md), [fixture/generator instructions](fixtures/release1-native/artifacts/README.md). |
| Source-6 atomic batch review | Included valid and excluded invalid raw rows survived forced-stop recovery; repaired two-source Apply and complete Save/Undo/Redo source comparisons passed. [Native report](release-current-native-verification.md). |
| Scenario ordered-member variant | At1100×700, Take rejected ambiguous insertion; explicit final order retained the local self-test. Complete Apply/Save, Undo/Save and Redo/Save matched the independent source oracles with only the schema5→6 header token upgrade. All three saves succeeded first attempt. Branch steps/fragment branches and this variant's crash recovery remain separate cases. [Exact native report](release-current-native-verification.md). |
| Native guide navigation | On current guide binary at1100×700: related Scenarios-bottom→Exchanges opens the new heading; filtering `exchange` retains the current topic's bottom position; `Git` auto-selects Build first and opens its heading. No dirty model. Root's actual native observations close these bounded scroll cases; [implementation/tests](release-semantic-conflict-diagnostics-20260906.md) remain separately scoped. |
| Communication means | Drawing/create/reuse and legacy reverse full-model/source/history passes are retained. Corrected reverse Apply now opens the explicitly requested OA scenario in Behavior, preserving the original four-object Architecture. Distinct oracle predicts10UUIDs/zero placements; accepted model/all3sources, Undo baseline, Redo and reopen pass. Every Save succeeded first submission. Navigation5focused tests, strict Clippy and bins build pass; compiled desktop535 is not a full535 run. [Exact report](release-communication-native-20260906.md), [implementation](release-behavior-transition-context-20260906.md). |
| Teaching project and Home hook | Corrected94element/62relation/5view/68trace/30source example passes4expanded direct-rustc tests. Minimum-size Home/guide, raw-source guard, reviewed NameTake and exact source/history/reopen pass. Navigation fix is reverified. Additional data/interface/type drill-down, saved-view comparisons, invalid-view guard and typed Entry action selection pass. Fold/unfold and function rename/Undo/Redo each match complete model/all30source oracles, five first-submission saves; saved reopen retains the Entry target identity. Complete process/scenario/reuse/evidence lesson remains open. [Native report](release-teaching-native-20260906.md). |
| Child/Incident and source-5 recovery | Two-row attachment recovery and complete Apply/Save/Undo/Redo passed, every save first attempt. Exact old source-5 raw/base/include/path retention, manual repair and two-file Save passed. [Attachments](release-attachments-native-20260906.md), [source-5 native](release-source5-native-recovery-20260906.md), [independent review](release-source5-checkpoint-independent-review-20260906.md). |
| Dense saved views | Forty-label baseline and selected real relation identities inspected; filter, duplicate/hide, original10/copy9 persistence across restart and exact model oracle passed. Additional coverage/context intersections, empty selections and Names-and-items preview/Apply/Undo observed. Minimum-size overview requires working zoom/pan. Limits remain in [native evidence](release-current-native-verification.md). |
| Core/source/REST integration | Fresh `--all-targets` core run: **433 passed/1 ignored**,44 target summaries, exit0 in138.72s; fresh server run: **55/55**,4 summaries, exit0 in64.74s. Logs `.local/source7-core-all-targets.log`, `.local/source7-server-all-targets.log`; exits/timings in `.local/source7-current-gates-status.json`. These supersede the earlier combined core count and pre-budget-fix HTTP51 checkpoint. OpenAPI **72fixtures/204schemas/90leaves** and both strict reST renders pass. [Core checkpoint](release-source7-core-checkpoint-20260906.md), [API integration](release-source7-api-integration-20260906.md). |
| Source7 desktop authoring and recovery | Latest routing3/3 and full desktop **564/564 pass**; [routing checkpoint](release-contextual-route-native-fix-20260907.md) records exact logs. Earlier full desktop **561/561 passed**, zero failed/ignored,263.39s in `.local/source7-desktop-full-tests2.log`. The initial560/1 run exposed canvas scroll-state loss when a new conditional navigation control shifted its widget; a fixed navigation container corrected it, and the unchanged regression passed. Coverage includes qualified5, operation3 (selected Async request fields), semantic source7 facets/omission3, recovery8, legacy source5 13, artifact search2 and focus guard1. Exact old-version enum/cache-path intent rejection and raw text retention are covered. The complete-scope endpoint picker preserves access beyond512; canvas preview remains bounded. Guide now accurately describes attachment/artifact reconciliation and artifact filtering. [Desktop checkpoint](release-source7-desktop-authoring-20260906.md), [recovery](release-source7-recovery-20260906.md). |
| Windows strict/build checkpoint and native7 | Strict workspace/all-target Clippy passed2m50s; root observed final format exit0/empty log. Three affected semantic tests passed3.46s after equivalent lint edits; native build exit0 recorded in `.local/source7-current-gates-status.json`. These earlier results scope the6BAB binary, not the later routing test binary or pending new strict/build sequence. Reset/ReadStatus full model/all-source Save/Undo/Redo/reopen pass. OA First.B persistence passes but routing acceptance remains open. Old6 Recover preserved the complete30-file bundle/workspace/Ports DTO, exact spaces/Unicode/fingerprint/reserved identity; Cancel/Save as and JSON export passed full independent source/model equality. Original seed unchanged. Old5 complete accepted/raw recovery, exact repair/30-source Save and full-model export pass. Current7 invalid nested draft crash recovery plus completed link Save/Undo/Redo/reopen pass; rendering still uses the older binary. [Native report](release-source7-native-acceptance-20260907.md). |
| Current Linux source7 and cross-built probe | Frozen native server compilation passed17m10s; unit2/2 and HTTP50/51, with one timing-dependent504-vs-412 assertion reproduced twice. No complete server pass; later targets not claimed. Native core436passed/0failed/2ignored; VM cleanly off08:13:56UTC. Separately, the complete Windows macro/build-script cross-build probe's hash-verified ELF executed successfully on Linux; this is neither a full desktop build nor GUI acceptance. [Native Linux gate](release-source7-linux-gate-20260907.md), [cross-build probe](release-linux-cross-build-probe-20260906.md). |
| Historical Linux/MSRV core and server | Ubuntu24.04.4/x86_64/glibc2.39/ext4/Rust1.90: core38/38, patched journal4focused/42full and3explicit syscall fault cases pass on recorded snapshots. Actual server build passes34m42s including3m24s pause. Real HTTP modular import, invalid PUT unchanged source/ETag, clean SIGTERM and exact model/source/ETag restart pass on the older28-source lesson snapshot. Full server test command timed out while compiling; zero tests executed. That gate shut down cleanly21:53:56; the separate current gate has the scoped results above. Current desktop/Linux package unverified. [Linux report](release-linux-validation-options.md), [journal contract](release-linux-journal-publication.md). |
| Packaging foundation | Portable Windows QA staging, dependency/runtime/font/Rust notices, archive readback and clean-PATH smoke passed at earlier binaries. [Package report](release-windows-package-review.md). QA archives are not current final release artifacts. |

Historical full platform/native milestones retain their original revision scope; [complete prior ledger](history/2026-09-06-ledgers-before-consolidation/STATE.md) preserves all evidence links and previous environments. A test or native pass never transfers automatically to a changed executable.

## Active findings and checks

Native artifact review exposed same-row conflict wording and reserved identities shown as deleted. Corrections retain typed actual-slot equality, row-addressed reservations and accepted-identity precedence; independent re-review found no further material defect. The completed108-semantic/527-desktop checks supersede the earlier interrupted run and include reserved-label/partial-creation regressions. Revised artifact wording still needs its own native observation on the current binary. Guide-scroll implementation/tests/build and the bounded native cases above passed. [Diagnostic/guide report](release-semantic-conflict-diagnostics-20260906.md).

**F1** teaching onboarding/review/history has current-binary native evidence; remaining tutorial work is scoped in its report. **F2**, faithful behavior-canvas SVG export, is deferred by root's scope decision: export remains architecture-only and must be described that way; no faithful scenario/process/state SVG acceptance is claimed.

Reverse scenario's first-dependency focus/overlapping architecture placements and teaching NameTake's separate layer/view mismatch are fixed and natively reverified. Latest NameTake4focused tests, strict alltargetClippy28.26s and binsbuild50.50s pass; no full539desktop pass is claimed. [Navigation evidence](release-semantic-review-navigation-20260906.md). Minimum-size process working space is cramped; native lesson evidence records23% overview versus100% scrolling rather than claiming readability at Fit.

Independent scope reconciliation verified **S1** missing contextual assembly into repeated/nested process references and **S2** missing maintained interface-operation identity in parameterless messages. Isolated existing-core probes falsify the proposed workarounds. Root ratified the jointly critiqued [source7 integration decision](release-source7-integration-decision-20260906.md), including deterministic cache-independent admission, whole-link deletion, purpose-specific analysis, exact Call-derived operation/Reply identity and one frozen old5/6 checkpoint migration. These contracts now have implemented core/source/REST/desktop/recovery paths and the current automated gates above; remaining native7 and current Linux acceptance remain incomplete. [Scope reconciliation](release-scope-reconciliation-20260906.md).

Linux ordinary rename's empty-target replacement was independently reproduced and corrected using `renameat2(RENAME_NOREPLACE)` without fallback. Exact errno/no-write assertions now pass under actual syscall injection. This establishes the ext4 publication invariant, not power-loss durability, hostile ancestor protection or model-file compare-and-swap. Windows retains its no-replace API and bounded scanner retries.

## Remaining gates and next actions

1. Fit implementation/review and automated gates are complete, including full570 desktop tests. Finish its native minimum-height/Focus/pending-form checks when native control resumes. Preserve completed BCC1 routing and old5/old6/current7 recovery/source/history oracles. Complete remaining current-binary S1/S2 purpose workflows and teaching cases; operation allocation deletion remains subject to independent channel validation. Native-check revised reserved labels and same-row conflicts. The later guide-only control-label correction passed formatting, independent review and the fresh workspace-binary build; it awaits the next packaged/native release snapshot.
2. Close uncovered selective-view lifecycle cases; advanced ordered/process/scenario/fragment variants beyond the accepted Scenario case; typed state actions and pending Linux data/hosted/compact workflows. Implemented semantics must not be called missing merely because acceptance is outstanding; [coverage audit](release-current-coverage-20260906.md) is the baseline map, newer scoped reports supersede its old gap claims.
3. Verify complete current Linux integration suites and desktop/server build/runtime, then supported-size native workflows. The successful core/MSRV pilot is a reusable starting point, not application acceptance.
4. Preserve current strict Clippy/format/reST/example/source/OpenAPI results and rerun affected checks after changes. Complete optimized/MSRV/final platform gates, actual hosted transport variants and final migration/package checks. Rebuild portable distributions from the accepted exact tree, validate notices/runtime/content/checksums and clean-environment launch before replacing old bundles.
5. Conduct fresh independent requirements/domain/parity/architecture/runtime/UX/end-state reviews; resolve material findings. Commit/integrate authorized source with reviewable scope; remote publication is not requested. Only complete the goal when its applicable criteria are met.

Meaningful progress continues: native lifecycle and Linux no-replace uncertainty have been resolved with exact oracles. The highest-value work is current-binary validation and closing uncovered engineering workflows, not accumulating repeated historical headings or treating aggregate test counts as release completion.
