+# Editing workspace UX review
+
+These development criteria implement the [project goal](../PROJECT_GOAL.md): reduce system engineers' cognitive load, keep graphical editing intuitive, and provide concise, navigable built-in help. They also address the user's request tracked in Gitea issue #39 to prevent persistent instructional text from consuming editing space. They are review criteria, not a claim that any particular build has passed them.
+
+## Persistent content and progressive disclosure
+
+Populated editing workspaces prioritize model content, controls, current state and actionable feedback. General explanations, gesture tutorials and repeated shortcut lists belong in contextual Help, tooltips or explicitly opened details. Do not add permanent instructional paragraphs above a populated canvas merely to explain a feature.
+
+Keep essential control labels and relevant status visible. Offer concise next-step guidance in empty states and while a user is performing a multi-step action. Put longer explanations behind a clearly labeled disclosure near the relevant control or context. Essential instructions must be accessible through an explicit keyboard-reachable route; a hover-only tooltip is insufficient. Reuse the built-in guide for broader modeling explanations.
+
+Distinguish instruction from information needed to act safely. Current errors, pending edits, failed operations, fallback rendering, unavailable actions and recovery steps must remain apparent. Preserve consequential distinctions such as editing a shared definition, changing semantic order rather than saved positions, or applying properties to only one member of a selection. Long diagnostic detail may be disclosed on demand, but its visible summary must identify the problem and a usable next step.
+
+## Stable editing context
+
+Selection changes and gesture feedback must not unexpectedly move or resize the canvas, reset its camera, or change the interpretation of the pointer. Compact existing stable layout slots instead of conditionally removing them when their content is absent. Opening and closing help must preserve the model, selection and pending drafts, and return the user to a usable editing context. Explicitly requested panel changes may resize the workspace; verify their effect on focus and navigation.
+
+## Native review
+
+Exercise the changed workspace in the actual built application at its configured minimum window size and a representative normal size. Include an independent reviewer for material interaction or layout changes, following [the working agreement](../AGENTS.md). Review representative populated models as well as relevant empty, pending, failure and recovery states.
+
+- Inspect whether instructional prose or unused space displaces useful model content. Compare before/after screenshots at the same window size, display scaling, model and panel state when assessing space savings.
+- Perform the affected workflow: select, edit, navigate, cancel and recover as applicable. Change between empty, single and multiple selections; exercise affected gestures and inspect camera and pointer stability.
+- Find and use the disclosed guidance by keyboard as well as pointer. Check focus, dismissal, return to editing, and preservation of drafts.
+- Trigger relevant disabled or rejected operations. Confirm their reason and recovery action remain visible, accurate and reachable.
+- Check text, controls, panels and warnings for clipping, overlap, excessive scrolling and lost actions at the minimum size. Do not trade recovered space for unreadable text or unexplained symbols.
+
+Record the tested code version, runtime environment, workflows, observations and representative screenshots in the change's review evidence. Screenshots support layout findings; they do not establish working interaction, accessibility or state preservation. Fix material findings and recheck affected behavior before treating the change as verified.

+# Compact diagram controls and contextual help
+
+Branch-specific work for [issue 39](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/39), based on published preview source `715036e132677dd2bc2fb37ed316d93dc9987aec`.
+This record does not accept the complete first release or the other diagram defects.
+
+## Problem and choice
+
+The user's screenshot showed two permanent Traceability explanation paragraphs and a separate generic gesture-hint row. Direct Windows inspection of the released water-pressure example reproduced these. At a 1100×700 client size (1102×732 captured window), the Traceability canvas began around window y=470 and ended around y=692, leaving about 220 pixels for modeling. At the normal 1440×900 client size its top was around y=417. The release was opened from the existing downloaded package; only an in-memory projection switch was made and Undo restored the clean model before closure.
+
+The candidate moves general instructions into contextual Help, reusing the offline guide. Architecture, State and Process selection bars use a stable compact row. Allocation retains its full-width destination slot; a concise Arrange control sits beside the existing view-content and Help controls. Traceability retains its displayed-line count and existing actions. Active drawing/assignment feedback appears beside the operation outcome in the persistent status bar, with full text on hover. Operation errors must never be replaced by generic guidance.
+
+Help opens as an overlay and closes with Close or Escape. F1 opens the relevant diagram topic. The workspace, selected group, pending source/property/behavior drafts and camera remain owned by their existing state. Background user commands are rejected before specialized canvas/reference dispatch. Passive results retain their established validity checks. The editor remains the first child of a stable Stack while Help opens and closes.
+
+Rejected alternatives: ordinary navigation to the Guide page cleared selection and could reject Help while a behavior draft was pending; placing feedback beside the entire selection toolbar exhausted narrow-window width; unconditional status substitution hid operation failures. Independent source review identified these before acceptance. Hover-only help was rejected because the complete instructions need a keyboard-accessible route.
+
+[Editing workspace UX review](../docs/ui-review.md) is the development/review contract requested by the user. It covers persistent prose, actionable feedback, context preservation and independent native interaction checks.
+
+## Verification status
+
+Clean source `f83068757af885572f6b3f932d07233dd1b94b7e` passed `cargo build -p oa-desktop --locked` on Windows gnullvm. Its candidate executable SHA-256 is `c1a9b196ec03e86f049fa2aadb2b86bfcaa3f0fbae582a80ee39ee8adf0758e3e`. The [independent source review](compact-context-help-source-review-20260925.md) records the corrected source findings, including passive viewport updates while Help is open.
+
+Independent native review of that executable recovered approximately 61 pixels in normal Traceability, 114 pixels in minimum Traceability and 58 pixels in minimum Allocation. Help resizes, pointer-scrolls, selects the State topic, and closes through Close/Escape. The review also reproduced two acceptance failures: PageDown cannot scroll Help, and F1/Escape preserves a property or Process-creation draft but loses typing focus/caret continuation. These findings require correction and another native check; model-state unit tests alone do not cover internal widget focus. The idle State-canvas gesture sentence is also removed in the successor; active/pending and hovered-item feedback retain their stable slot.
+
+The initial focused test run passed nine and failed one: the allocation test fixture used the default Overview projection before asserting allocation ownership. A separate ten-case mounted geometry run passed nine and failed the destination's existing 400-pixel minimum-width check. Sharing its row with the verbose Arrange action reduced that slot to 328 pixels at minimum size. The successor fixes the fixture explicitly and restores the full destination row without weakening its width check. The original failed logs are preserved in the [native/test evidence](experiments/compact-help-20260925/README.md). These diagnostic runs began before the successor edits and are not frozen-source acceptance of those edits.
+
+Frozen successor `5657a996ed2cefb1fa84ef967b655eaf8f9f6817` passed formatting, strict all-target desktop Clippy and the Windows GUI build. The full desktop run passed 1,538 tests, ignored seven and failed one new mounted Help test before Help opened: its synthetic multi-character KeyPressed event inserted only the first character, as the actual Iced text input specifies. The final correction sends individual character events and retains the exact-caret, scrolling and IME assertions. The existing allocation width and ownership checks and new modifier/pointer cancellation checks passed. See the [preserved successor evidence](experiments/compact-help-20260925/candidate-5657/review.md) and logs; the failed run is not reported as a passing suite.
+
+Independent native review of that exact executable confirmed keyboard Help scrolling, precise Inspector and Process-draft caret continuation after Help, resize, retained State tool state and complete allocation-error tooltips. Minimum Allocation recovers approximately 64 pixels with the full destination slot; minimum Traceability recovers 114 pixels. The reviewer found no new blocker within that scope.
+
+Final source `6e7c4ddaf0775198384a8c4882809ea8e14b2976` passes formatting, strict desktop/all-target Clippy, GUI build and 125 focused Help/allocation/guide tests (zero failures/ignores). The corrected mounted caret test now executes its complete assertions. Unchanged evidence from the earlier full run is retained at its original source; the remaining 1,421 desktop cases were not rerun at the final source. The initial final GUI link failed when the disk filled; after the user expanded the disk, the same-source rebuild passed. The failed log remains preserved.
+
+The [final native report](experiments/compact-help-20260925/candidate-6e7c/review.md) directly verifies cancellation status, guide wording, native group selection through context menus, primary Inspector changes, long-name controls at minimum size, exact caret return after both Help dismissal routes, and Apply/Undo/Redo/Undo recovery. Independent source review found no blocker in the final small delta. The watcher records exit 0 and empty stdout/stderr; all 37 copied model files still match the original after closure. An early transient OSK/modifier obstruction occurred before model loading and is recorded separately from app behavior. No blocking defect was found within this contribution's review scope. Shared integration and release admission remain in issue 39; full product completion is not claimed.
+
+Required native checks: minimum and normal windows; Traceability and Allocation space comparison; multi-selection with long names; Help/F1/Close/Escape with property and behavior drafts; editor focus and canvas scroll/camera restoration; active feedback plus operation failure; State and Process controls; subsequent edit/Undo/Redo and source preservation. Linux remains deferred under the recorded user instruction.

+# Compact contextual help: independent source review
+
+Review date: 2026-09-25. Scope: Gitea issue #39 compact editing chrome and contextual Help, reviewed against base `715036e1` and the issue screenshot. Reviewed source includes `e0812b3932fbb36100516f0981dc9c646eeda56d` plus the subsequent local passive-geometry admission patch and regression test in this change. This is source-review evidence, not native acceptance or executed test evidence.
+
+Criteria: [editing workspace UX review](../docs/ui-review.md), especially preserving pending edits and selection, stable canvas geometry, accessible disclosure, and retaining actionable feedback.
+
+## Findings addressed in source
+
+- The initial Help action used ordinary page navigation, clearing multiselection and selected bends, including before a pending behavior form rejected navigation. Contextual Help now overlays the existing workspace. Close/Escape changes reading state without navigating or applying drafts.
+- App-level modal admission originally ran after allocation and reference-picker fast paths. Help now gates user messages at the beginning of `App::update`; allocation and behavior keyboard ownership are also disabled while Help is open.
+- Combining live gesture feedback with multiselection controls could leave no width for feedback at the configured minimum window size. Selection controls now keep a compact, fixed-height row; current drawing/allocation feedback uses the existing application footer.
+- Footer feedback initially replaced operation status, concealing errors while a promoted edge or drawing tool remained selected. The footer now retains operation status alongside feedback and exposes complete text in its tooltip.
+- Conditional modal wrapping could recreate the editor widget tree. Both closed and open states now use the same outer Stack with the workspace as its first child.
+- State/Process selection guidance removed from persistent chrome was missing from its target Help articles. The States and Chains articles now include group selection, primary-properties semantics and relevant tool/read-only guidance.
+- The new early modal gate initially rejected passive behavior viewport/scroll notifications. It now admits Process/Scenario geometry and State viewport notifications to their existing context-validated handlers, preventing resize observations from being lost while Help is open.
+
+## Regression coverage added
+
+[`context_help_tests.rs`](../crates/oa-desktop/src/app/context_help_tests.rs) covers property drafts and multiselection, source drafts, pending state-transition forms, blocked background actions, contextual Help topic dispatch, Close/Escape, allocation input ownership, queued inspector reference-picker admission, and valid/stale Process viewport measurements during Help and after closing. Assertions include accepted-model snapshot identity and absence of history changes where applicable. Passive geometry intentionally validates document/owner/revision; stale pointer epochs alone do not invalidate measurements.
+
+The reviewer did not compile or execute these tests. Suggested focused command: `cargo test -p oa-desktop context_help_tests`. The integration owner records actual execution and native results separately.
+
+## Follow-up from native review
+
+Native review of the subsequent candidate found that contextual Help did not respond to PageDown and that Escape reached a focused underlying text input, dropping its typing focus. The follow-up patch adds a Help-only keyboard subscription and article-ID-targeted scrolling (40-pixel arrows, 90% of the actual viewport for PageUp/Down, Home/End), using Iced's bounds-clamped scroll state. A stable workspace input barrier preserves the actual editor caret while suppressing key, pointer, touch and IME input behind Help; modifier changes and passive geometry continue. Opening Help retires held pointer gestures through cancellation releases with all authored actions discarded, while forwarding redraw/layout invalidation. This also prevents a held canvas pan or text selection from resuming after release behind Help.
+
+New mounted regressions exercise the production App tree and subscriptions for keyboard scrolling, unchanged background scroll positions, precise Inspector caret return, IME exclusion, Shift release, and held-pan retirement. A real text-input widget regression checks selection-drag retirement while preserving its caret. The allocation ownership fixture was corrected to explicitly request Allocation, because `ensure_diagram` creates Overview. These follow-up changes were formatted and source-reviewed here; compilation, execution and native acceptance remain the integration owner's checks.
+
+A second, read-only critic reviewed the follow-up independently of its implementation. It found and prompted corrections for stale modifiers, IME leakage and interrupted pointer gestures. Its final read found no further blocking source defect in the input barrier, cancellation, passive-event handling or relocated Arrange control. The separate native reviewer supplied the original keyboard/focus failures. Neither source review establishes executed or native acceptance of the successor.
+
+## Scope and remaining verification
+
+A final independent read-only source review covered the small post-`5657a996`
+delta. It confirmed that the mounted typing fixture must send one KeyPressed per
+character because Iced consumes the first scalar, with the original caret/IME
+assertions retained. Arrange cancellation now replaces only its own obsolete
+armed status, preserving unrelated errors; input epochs and model commands are
+unchanged. The guide names the actual Arrange control. No blocking finding was
+identified in that delta. Actual executed and native evidence remains separately
+identified by source in the design record and evidence index.
+
+Production changes reviewed: desktop App messages/admission, allocation input ownership, Escape bridging, behavior keyboard ownership, architecture/State/Process toolbar layout, guide article disclosure and footer feedback; supporting architecture/UI-review documentation. Regression tests and this record are review artifacts. No model schema, persistence format or authored-model transformation is introduced.
+
+No further concrete source blocker was identified after the fixes above. Native checks remain necessary at 1100×700 and a representative normal size: Help discovery and keyboard reading/dismissal, focus and caret return, preservation of canvas camera/selection and form drafts, resize while Help is open, multiselection control visibility, allocation refusal/destination feedback, current operation failures, and stable canvas bounds through selection/gesture changes. Source inspection and App tests do not establish layout quality, keyboard scrolling, pointer behavior or usability.

+source is `6e7c4ddaf0775198384a8c4882809ea8e14b2976`. It removes permanent canvas
+instructions, preserves compact stable controls and offers contextual Help/F1.
+Model schema, core, server, dependencies and persistence code are unchanged.
+
+[Decision and acceptance boundary](compact-context-help-20260925.md),
+[independent source review](compact-context-help-source-review-20260925.md),
+[native reports, screenshots and gate logs](experiments/compact-help-20260925/README.md)
+and [development UX criteria](../docs/ui-review.md) are authoritative for this change.
+
+Windows gnullvm / Rust 1.98.1: formatting, strict desktop/all-target Clippy and the
+GUI build pass. Final focused run: **125 passed, zero failed/ignored**. Earlier
+full desktop execution at `5657a996` passed 1,538, failed one new test's typing
+setup and ignored seven; the corrected test executes fully in the final passing
+run. This is not a claim of a full-suite run at the final commit. The initial
+final link failed with a full disk and is retained; the recovered build succeeds.
+
+Final Studio SHA256:
+`d55ecad4b0f75c0c9c26625e5441bef9c9360890b65bc13236c6ebfaf03d631e`.
+Matching runtime SHA256:
+`f45604a12e8bcd839fd86f667c1be1cc7c4f9da2b3c69ff381ac708f0e1ae7d4`.
+
+Independent native checks pass group selection/primary properties, Help dismissal
+and exact caret continuation, long names at 1100×700, Arrange cancellation,
+guide consistency and Apply/Undo/Redo/Undo. Earlier versioned native checks cover
+Process drafts, State tools, Help resize and actual operation refusals. Minimum
+Allocation recovers about 64 pixels; minimum Traceability about 114 pixels.
+Final process exit is 0, both logs are empty, and all 37 copied example files
+remain unchanged. Native counts do not establish whole-Project equality; mounted
+regressions provide the separately scoped model/history checks.
+
+The application remains an unfinished development preview. The separate
+projection/navigation, outgoing-drag, icon, grid/performance and State-label
+contributions are outside this source. Dense routes/labels, remaining Scenario
+group adapters, quantities/calculations/constraints, maintained libraries,
+complete OA/SA acceptance and broad accessibility/DPI coverage remain unfinished.
+Linux/WSL checks remain excluded by the user's recorded instruction. This change
+does not accept the complete first release.

+# Compact Help native evidence
+
+Branch-specific evidence for [issue 39](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/39).
+The [design record](../../compact-context-help-20260925.md) owns the decision and current acceptance boundary.
+
+`native/` contains the Windows baseline captures from published source
+`715036e132677dd2bc2fb37ed316d93dc9987aec`.
+`candidate-f830/` preserves the independent review of source
+`f83068757af885572f6b3f932d07233dd1b94b7e`, including its two failed Help workflows,
+original screenshots, exact executable/runtime hashes and successful build log.
+These observations must not be relabeled as acceptance of a successor executable.
+
+`candidate-5657/` preserves the next frozen source's build, strict all-target
+Clippy, full desktop test log and independent native review. Formatting, Clippy
+and build passed. Tests: 1,538 passed, one failed, seven ignored. The sole failure
+was the new caret test's synthetic typing setup before Help opened; `help-failure.log`
+records its exact rerun. The next correction uses one character per key event.
+The native report records corrected Help keyboard/caret behavior, minimum-window
+layout and real operation-refusal feedback, with explicit scope limitations.
+Copied text logs have normalized line endings and trailing blank lines removed;
+original local logs are retained. Image and fixture hashes are unchanged.
+
+`candidate-6e7c/` preserves final source
+`6e7c4ddaf0775198384a8c4882809ea8e14b2976`: formatting and strict desktop/all-target
+Clippy pass, the recovered GUI build passes, and 125 focused Help/allocation/guide
+tests pass with zero failures/ignores. `build-diskfull.log` preserves the first
+failed link; no code change was needed for the recovered build. Its native report
+and 15 screenshots cover cancellation, guide consistency, group/primary selection,
+minimum-window long names, exact caret return and Undo/Redo/Undo. The runtime
+receipt confirms exit 0 and empty logs. Post-close baseline comparison confirms
+all 37 copied fixture files unchanged. The transient OSK observation happened
+before loading the model and is explicitly retained. Prior source-specific
+workflows remain attributed to their actual binaries.
+
+Reproduce final code checks on the documented Windows gnullvm/Rust 1.98.1 toolchain:
+
+```powershell
+cargo fmt --all -- --check
+cargo clippy -p oa-desktop --all-targets --locked -- -D warnings
+cargo build -p oa-desktop --locked
+cargo test -p oa-desktop --locked -- context_help_tests allocation_drag guide::tests --test-threads=1
+```
+
+The initial test compilation began at that commit; successor work was edited
+while it ran. `tests.log` (nine passed, one failed fixture precondition) and
+`geometry-tests.log` (nine passed, one failed destination-width invariant) are
+diagnostic evidence from that cycle, not frozen-source acceptance. The geometry
+run reused its test executable without recompiling. The first command's
+`allocation_drag_full_tree_tests` filter matched no tests; the second used the
+actual `full_tree` filter plus the affected mounted State/Process checks.
+
+The review used a copy of `examples/release1/project.arcadia` from the published
+Windows package. All 37 fixture files matched the baseline before the trial and
+again after closing without saving. `baseline-proof.json` records those bytes.
+The executable is a local development build, not a published release artifact.
+
+Reproduce the build using the documented Windows gnullvm toolchain and
+`cargo build -p oa-desktop --locked`. Place its matching `libunwind.dll` beside the
+executable, launch it, and open an isolated copy of the release1 example. Perform
+the workflows and use the window sizes in [the native report](candidate-f830/review.md).
+The baseline captures establish layout comparison; the report records actual
+interaction results and explicit unverified workflows.

+# Independent native successor review
+
+Reviewed source `5657a996ed2cefb1fa84ef967b655eaf8f9f6817`; executable SHA-256 `83CCEFF8B713491AFEE92FFCAFE62B02F5EEA6A3D899F6F334848FDC7BB0D88D` independently rechecked after the run; runtime SHA-256 `F45604A12E8BCD839FD86F667C1BE1CC7C4F9DA2B3C69FF381AC708F0E1AE7D4` from build.json. Used Windows native Computer Use, the isolated `model/project.arcadia`, normal 1440x900 and minimum 1100x700 client sizes (1442x932 and 1102x732 captures). The prior candidate report remains historical under `../candidate-f830/review.md`.
+
+## Result
+
+Both prior blocking native findings are corrected in the exercised workflows. No new blocking finding was observed in this bounded retest. This is not complete product, accessibility, multiselection or first-release acceptance.
+
+### Help keyboard reading and caret preservation
+
+1. In normal Allocation, focused inspector Name, selected its text, typed `LEFT RIGHT`, and pressed Ctrl+Left to put the caret before `RIGHT`. Opened Help with F1. PageDown visibly scrolled to lower sections; PageUp returned to the top; End reached the bottom; Home returned to the top; Down moved one increment and Up reversed it. Evidence: `02-help-pagedown.png`, `03-help-end.png`.
+2. Pressed Escape, then typed `X` without refocusing. Name became exactly `LEFT XRIGHT`. Reopened with F1, clicked visible Close, then typed `Y` without refocusing. Name became exactly `LEFT XYRIGHT`. Thus keyboard reading did not move the background caret, and both dismissal paths preserved input continuation. Evidence: `04-caret-after-escape.png`, `05-caret-after-close.png`. Revert restored the accepted property.
+3. Opened Help again and resized the native window to its minimum width and height through the native system menu. Help reflowed with Close reachable; End still reached the bottom and Escape returned to the same diagram. Evidence: `06-help-minimum-resized.png`.
+4. At minimum size, opened System functional chain `Handle a pressure alarm`, chose W, clicked blank canvas, and entered `LEFT RIGHT` in the pending contribution Name. Ctrl+Left, F1, End, Escape, then `X` produced exactly `LEFT XRIGHT` without refocusing. Create remained disabled with its missing-source explanation and Cancel reachable. Cancel preserved the accepted model. Evidence: `15-process-caret-restored.png`.
+
+### Compact controls and actionable feedback
+
+- Normal and minimum Allocation show projection, Help and Arrange together, with a separate full-width Destination slot. At minimum size the canvas begins near y=350 versus baseline y=414, approximately 64 pixels recovered. Changing from no selection to a selected work card and exercising refused drags did not move the canvas boundary. Evidence: `01-allocation-normal.png`, `07-allocation-minimum.png`.
+- Clicking Arrange displays `Arrange ✓`; the tooltip explains one-drag scope, Alt+A and Escape. Escape removes the check; Alt+A arms it again. Evidence: `08-arrange-tooltip-armed.png`.
+- With Arrange armed, dragged `Assess pressure alarm` from Control room toward Field technician. The operation was refused with the visible footer message `Make room or adjust the view, then drag again. Zoom in to read the work and destination.` The accepted model remained saved and the work stayed allocated to Control room. Evidence: `09-arrange-refusal.png`.
+- Repeated the drag without Arrange. Core validation refused the reassignment with `exchange_allocation_performer: Actual activity allocations must agree with one permitted communication direction; review the means or the activity allocations.` The shortened footer remained visible, and pointing at it exposed the complete readable explanation. The selected activity and accepted model remained unchanged. Evidence: `10-assignment-refusal.png`, `11-refusal-tooltip.png`.
+- Changed View content to Traceability. Count, Add existing elements, Review layer traces, View visibility and Help all remain reachable at minimum width. Canvas starts near y=356 versus baseline y=470, approximately 114 pixels recovered. Undid this temporary projection change. Evidence: `12-trace-minimum.png`.
+- Opened saved State view `5 · SA pressure supervision`: the generic idle canvas instruction is removed. Choosing +Region still shows its active creation prompt. F1 opens the States topic; Escape returns with +Region still selected, without creating an object. Evidence: `13-state-idle.png`, `14-state-active-prompt.png`.
+
+## Limitations and minor observations
+
+- The existing State active prompt still truncates at minimum width (`Create Region ... machine or composite s...`). This retest confirms it was retained, not that every pre-existing State prompt has complete narrow-window readability.
+- The compact control says `Arrange`, while the guide still says `Arrange next drag`; its tooltip explains that wording. Minor consistency cleanup was reported to the integration owner; no user workflow failed because of it.
+- Modifier-click/native multiselection and long-name group toolbar layout were not independently operated because the supported Computer Use API has no modifier-click/key-hold operation. Do not infer them from the single-selection screenshots. The parent owns mounted-widget verification separately. Source-editor caret behavior and full Scenario workflows were not repeated in this bounded successor retest.
+- The approved native launch API does not expose stdout/stderr or process exit status. After Alt+F4, refreshed native window enumeration confirmed both successor application and console windows disappeared. No crash dialog was observed; this is not an asserted exit code or log inspection.
+
+No save was performed. A post-run hash comparison against baseline-proof.json found no changed files among all 37 copied fixture files. The UI returned to the saved baseline with 94 objects, 62 links and one model check before closure. Screenshots are supporting evidence; the results above describe actual input and observed responses.

+# Final native UX retest
+
+Independent review by `/root/ux_critique`, using Windows Computer Use (`@oai/sky`). Final preparation and launch began on 2026-09-29; the resumed input session completed on 2026-10-01 America/Los_Angeles (completion clock: 2026-10-02 00:42:55 UTC).
+
+## Identity and scope
+
+- Source: `6e7c4ddaf0775198384a8c4882809ea8e14b2976`.
+- Executable: `.local/native-final/arcadia-studio.exe`, SHA-256 `D55ECAD4B0F75C0C9C26625E5441BEF9C9360890B65BC13236C6EBFAF03D631E`.
+- Runtime: `libunwind.dll`, SHA-256 `F45604A12E8BCD839FD86F667C1BE1CC7C4F9DA2B3C69FF381AC708F0E1AE7D4`.
+- Read build identity from `build.json`. Parent launched this executable with a stdout/stderr/exit watcher; reviewer selected its unique returned native window and did not launch another executable.
+- Model: only `.local/native-final/model/project.arcadia`, copied from the released water-pressure fixture. `baseline-proof.json` records its 37 original file hashes and baseline source/binary identity. No Save was performed.
+- Normal window: 1440x900 client, captured 1442x932. Minimum: 1100x700 client, captured 1102x732. Same native environment and baseline fixture as prior review.
+
+This is a bounded final-delta retest plus previously missing native group-selection/long-name coverage. The earlier `../candidate-5657/review.md` remains historical evidence for Process draft, State, Traceability, refused allocation, and resize-with-Help workflows on source `5657a996...`; those are not silently relabeled as this binary's results.
+
+## Result
+
+No blocking UX defect found in the workflows below. The two final minor corrections behave as intended, and the newly exercised native group workflow passed.
+
+### Arrange cancellation and disclosed guidance
+
+1. In the populated Allocation view, clicked Arrange. The control displayed its check and footer showed the armed state.
+2. Pressed Escape. The check cleared and footer became `Arrange cancelled`, replacing the obsolete armed outcome. Repeated at minimum size with the same result. Evidence: `02-arrange-escape-cancelled.png`, `14-minimum-arrange-cancelled.png`.
+3. Armed Arrange again, then opened contextual Help with the pointer. Help opened and footer became `Arrange cancelled`. Visible Close returned to the same model and canvas. Evidence: `03-help-cancels-arrange.png`.
+4. Used PageDown to reach the relevant guide paragraphs. They now say `Choose Arrange` / `choose Arrange or press Alt+A`, matching the visible control, and explain right-click Add to selection / Inspect this element. Evidence: `04-guide-arrange-and-context-selection.png`.
+
+### Native group selection and primary inspector
+
+1. Clicked `Assess pressure alarm`; right-clicked `Repair valve in the field`; chose `Add to selection` from the ordinary context menu. Both cards gained selected outlines and the row displayed `2 selected`, `Hide selected`, `Clear`, and `Properties: Repair valve ... only`. Inspector showed the Repair activity. Evidence: `05-native-group-selection.png`.
+2. Right-clicked the selected Assess card and chose `Inspect this element`. Both cards stayed selected; Inspector switched to Assess and the row's `Properties: ... only` summary followed it. Evidence: `06-group-primary-inspector.png`.
+3. Opened F1 Help and dismissed with Escape. The same pair, primary inspector, canvas position and zoom remained. Evidence: `07-group-help-preserved.png`.
+4. Resized to the configured minimum through the native window system menu. The group controls remained readable and reachable, with the full-width Destination slot above them. The intentional resize refitted the view; subsequent selection/draft/help transitions did not move its canvas boundary. Evidence: `08-group-minimum.png`.
+
+### Long name, exact caret, Apply, Undo and Redo
+
+1. With both cards still selected and Assess as primary, focused its Name field and replaced the draft with `Pressure alarm assessment with a deliberately long operational activity name LEFT RIGHT`.
+2. Ctrl+Left placed the caret before RIGHT. Opened F1, pressed End to scroll Help, dismissed with Escape, and typed X without clicking the field. Reopened F1, used visible Close, and typed Y without refocusing. Pressing End in the restored field exposed the ending `LEFT XYRIGHT`. Thus both dismissal paths preserved the exact draft caret, not merely the draft contents. The pair and primary inspector also remained unchanged. Evidence: `09-group-long-draft-caret.png`.
+3. Clicked Apply changes. Only the primary Assess activity acquired the long name; Repair retained its original label. At minimum size, the selection row remained one stable row: count, Hide selected, Clear, and a shortened `Properties: Pressure alar... only` summary. The truncation did not hide the `only` distinction or an action. The Inspector Name field remained editable/scrollable for the complete name. Evidence: `10-long-name-group-minimum.png`.
+4. Clicked the non-editable summary row to leave the text input, then Ctrl+Z restored `Assess pressure alarm` and the UI's saved state. Ctrl+Y restored the long name and unsaved state. Ctrl+Z restored the original name and saved state again. The group remained selected through all three operations. Evidence: `11-long-name-undo.png`, `12-long-name-redo.png`.
+5. Clicked Clear. The group cleared, Inspector returned to view properties, and the canvas boundary and card positions remained stable. Evidence: `13-clear-selection-stable-canvas.png`.
+
+## Environment observation and limits
+
+- Initial Ctrl+O unexpectedly opened Windows On-Screen Keyboard, obscuring the target. Its screenshot showed a highlighted Windows key; another observation showed a different highlighted key without another keyboard action from this reviewer. Input was stopped and the parent notified. The keyboard was already absent on the next fresh window enumeration; reviewer did not close it or press any Windows-key control. Used pointer Open and a literal copied-fixture path to continue. Subsequent Escape, PageDown, F1, Ctrl+A, Ctrl+Left, Alt+Space, Undo/Redo and typing produced the expected target-app responses. This transient environment interference is preserved in `00-environment-input-interference.png`; it is not attributed to an application defect.
+- Native modifier-click remains untested; native group selection was genuinely exercised through the supported context menu instead. No multi-item drag/assignment was attempted in this final retest. Prior successor refused-drag evidence is separate.
+- Process/State/Scenario, source-editor caret, all Help navigation keys and resize while Help is open were not all repeated on this final binary. The final run directly exercised property draft/caret, group preservation, PageDown and End, F1/Escape/Close, minimum sizing and edit recovery. Full acceptance must combine the accurately versioned evidence rather than infer missing workflows from screenshots.
+- Saved-state labels, counts and visible Undo results do not prove whole-Project equality. This review made no Save; post-close byte-hash and watcher-log checks belong to the parent and are recorded separately.
+
+Before closure, UI showed `All changes saved`, original activity names, 94 objects, 62 links and one model check. Closed normally with Alt+F4. Fresh native window enumeration confirmed the final application's window was absent. Parent was notified to inspect watcher stdout/stderr/exit and fixture hashes. No crash dialog was observed; native window disappearance alone is not an asserted exit code.

+# Independent native review: compact contextual Help
+
+Reviewed candidate source `f83068757af885572f6b3f932d07233dd1b94b7e`, executable SHA-256 `C1A9B196EC03E86F049FA2AAD2B86BFCAA3F0FBAE582A80EE39EE8ADF0758E3E`, runtime SHA-256 `F45604A12E8BCD839FD86F667C1BE1CC7C4F9DA2B3C69FF381AC708F0E1AE7D4` (build.json). Review used Windows native Computer Use with the copied `model/project.arcadia`, normal 1440x900 and configured minimum 1100x700 client sizes (captured windows 1442x932 and 1102x732). Original examples and unrelated windows were not edited. This review belongs to this candidate, not a subsequently rebuilt executable.
+
+## Findings requiring correction
+
+1. **Help has no working keyboard reading route for overflow.** Open Architecture Help with F1. Press PageDown; the article does not move. Tab followed by PageDown does not move it. Clicking the article then PageDown also does not move it. Pointer wheel scrolling does work. Moved gesture instructions fall below the fold, so keyboard users cannot reach all the guidance. Evidence: `03-help-normal.png`, `04-help-keyboard-no-scroll.png`, `06-help-pointer-scroll.png`. Integration owner independently confirmed missing keyboard handling and is preparing a fix.
+2. **Help dismissal loses draft input focus/caret continuation.** In minimum Traceability, click inspector Name, press Home, type `DRAFT `, press F1, Escape, then type `X` without clicking. The retained field remains `DRAFT 1...`, rather than becoming `DRAFT X1...`. Repeat with Process W -> empty canvas -> pending contribution name `Review draft` -> F1 -> Escape -> type `X`; text remains `Review draft`. Draft text is retained and no model mutation occurs, but typing cannot resume at the previous caret. Evidence: `08-property-draft.png`, `09-property-focus-lost.png`, `14-process-pending.png`, `15-process-pending-focus-lost.png`.
+
+## Additional observation
+
+State still draws a permanent generic instruction at `behavior/state_canvas.rs:1500`: "Select / move ...". At the minimum width it is truncated near "transition endpoin..." (`11-state-minimum.png`). Move this idle instruction to Help while preserving active tool/selection warnings. This is separate from the removed toolbar hint.
+
+## Verified workflows and layout
+
+- Opened only the isolated copied water-pressure source project. Initial launch helper timed out waiting for a targetable window; a fresh window enumeration found the normal application. A file-dialog accessibility set-value operation also timed out; re-observation showed no filename change, and ordinary pointer focus/text entry succeeded. These are recorded as tooling delays, not application defects.
+- Switched OA Allocation to Traceability through View content. All trace actions remain visible. At normal size canvas top moved from baseline approximately y=417 to y=356; at minimum size from approximately y=470 to y=356. The same baseline fixture and panel state were used; this recovers approximately 61 and 114 vertical pixels respectively. Evidence: `02-trace-normal.png`, `07-trace-minimum.png`, baseline files under `../native/`.
+- Minimum Allocation canvas starts around y=356 versus baseline y=414, recovering approximately 58 pixels. Destination and Arrange controls remain visible (`10-allocation-minimum.png`). Arrange arms visibly and Escape removes its armed button state. The historical operation-status text remains in the footer after cancellation; no claim of full status-lifecycle coverage is made.
+- F1 and visible Help both open the overlay. Close and Escape dismiss it. Pointer article scrolling works. Resized the native window from normal to minimum while Help was open; header/Close and article remain reachable (`05-help-minimum-resized.png`). The underlying view remains selected after closing, and its camera updates to the smaller viewport.
+- Property draft text survives Help, and Revert restores accepted name. Undo restored the temporary Traceability projection change and the application showed all changes saved.
+- State and Process F1 select the correct States and Chains articles. Their compact selection rows and Help control are visible at minimum size (`11-state-minimum.png`, `13-process-minimum.png`). Created a State region, then exercised Undo/Redo/Undo; object and check counts returned to the fixture baseline (94 objects, 62 links, one check). Evidence: `12-state-redo.png`.
+- Process W -> blank canvas opens a pending contribution form. Named draft survives Help. Disabled Create, source chooser explanation and Cancel remain visible at minimum size. Cancel returned to the existing Process without creating an object.
+- Closed the reviewed application through Alt+F4 after restoring the clean model. No save was performed.
+
+## Remaining native coverage
+
+Do not infer multiselection, long-name group-control layout, source-editor caret preservation, operation-failure coexistence with active guidance, or full Scenario coverage from these observations. The supported Computer Use input API has no modifier-click or key-hold action; source inspection found Shift-click selection but no ordinary-diagram marquee implementation. Native group verification therefore remains a gap. Keyboard reading and property/behavior caret continuation must be rechecked on the successor candidate, together with any affected input behavior. Screenshots alone do not establish these interactions.

+# Incremental independent #39 evidence review
+
+No material blocker found in the added warning evidence or current release/checkpoint wording. This supplements the earlier final-evidence review, which covered the previous 133-entry packet; the current working-tree inventory has 140 entries, all independently rechecked against exact byte lengths and SHA256 with zero discrepancies.
+
+Reviewed the copied `read-model-warnings.py`, `model-warnings/{pristine,saved,result}.json` and logs, the existing complete model envelopes, the current release validation, packet README and top of STATE. No compiler, GUI, server launch, Gitea action or tracked-file edit was performed. This review file is the only new artifact.
+
+The added script performs GET validation requests for exactly the two resource IDs recorded by the prior complete-model oracle. Captured responses agree with result.json and show both models valid at revision 1 (separate imported resources). Pristine has only `work_without_behavior_context` for `4149a872-3440-59de-9879-8981e78d27ab`; saved retains that identical warning and adds exactly one warning: `trace_drift`, baseline field, `OaChanged`, trace `5309f955-53fd-5ff4-9c0a-91737e947341`.
+
+Independent full-model equality still holds after changing only Activity `61f7bbfb-74a4-5540-9182-2583dfb27a49` name from `Assess pressure alarm` to `Assess pressure alarm QA LEFT XYRIGHT`. The warned trace points to that activity. Its complete trace record and OA/SA review baseline remain identical; the OA baseline still says `Assess pressure alarm`. Thus the new warning is consistent with the existing trace_drift comparison in `crates/oa-core/src/transitions.rs`, not a silent baseline update or transition reconciliation. Both actual stored envelopes also remain identical to their earlier captured GET envelopes after the read-only validation run.
+
+The new README/release explanation accurately classifies one existing coverage warning plus expected OA name drift. It does not claim warning-free modeling. Current release validation and STATE do not assert that a new tag, release or assets are already published; historical published-release references remain distinct. Publication/readback acceptance and the separate #46 diagnostic correction remain outside this review.
+
+This review checks working-tree inventory bytes. The parent's scoped .gitattributes correction, restaging and indexed-blob/hash comparison are separate preservation gates and are not certified here. No snapshot byte normalization is authorized by this review.

+# Fresh package verification
+
+This packet verifies the exact scoped Windows development-preview ZIP described
+in [the release validation](../../../release-compact-help-validation-20261001.md).
+Production gates and earlier native evidence remain separately versioned in
+[the contribution record](../../../compact-help-validation-20261001.md).
+
+* [Independent artifact/server review](artifact-review.md): archive, provenance,
+  runtime/notices/docs, captured HTTP and restart scope, including the corrected
+  Unicode fixture.
+* [First native session](native/review.md) and [fresh reopen](native-reopen/review.md):
+  actual Home/help/edit/caret/minimum/save/history/reopen operations, original
+  collision refusal and recovery, screenshots and explicit limits.
+* `started.json`/`finished.json` in those native directories record system-only
+  PATH, unrelated cwd, executable/runtime hashes, exit 0 and empty logs.
+* `native-source-existing-save.json` and `native-source-destination-*.json`
+  record the declared whole-file oracles. `saved-source/` preserves actual
+  changed source and relocated entry bytes; all other hashes refer to pristine
+  files distributed in the ZIP. Companion files were copied separately.
+* `native-model-oracle/` retains requests/responses and result of parsing the
+  complete pristine and actual saved bundles using the exact packaged server.
+  Only the declared Activity name differs in the complete Project. Fresh
+  independent read-only reconciliation also verifies actual disk/source equality.
+* `model-warnings/` records subsequent read-only validation: both models are
+  valid; the name edit adds the expected OA trace-drift warning to the existing
+  behavior-coverage warning. Transition reconciliation was not performed.
+* `server-smoke/` preserves the first harness fixture encoding issue;
+  `server-smoke-unicode02/` retains its corrected U+2014/CRLF run. Each preserves
+  all 11 HTTP exchanges, source files, acknowledged envelope and process results.
+  Stores are not duplicated; captured envelopes and store hashes are retained.
+* `extraction-check.json` covers all 565 extracted files; `package.json` and
+  `build-evidence.json` identify distinct source roles. Runtime/dependency notice
+  inventories and their full texts remain inside the actual ZIP.
+* [Evidence file hashes](evidence-files.json) bind these exact copied bytes.
+
+Helpers are retained as executed, with their original absolute machine paths.
+Adapt paths to a fresh extraction/working directory to repeat a workflow. Do not
+overwrite prior attempts. Source checks and package reconstruction parameters
+are in the release validation and `docs/windows-packaging.md`. These finite
+checks do not establish complete OA/SA, general accessibility, Linux, power-loss
+safety or application-managed copying of arbitrary external artifacts.

+# Independent compact Help package and server evidence review
+
+No blocking finding in the reviewed artifact integrity, provenance, notices, or bounded server evidence. This review does not accept the packaged desktop workflow or the complete first release. The reviewer performed read-only byte/JSON/PE checks and inspected existing runtime evidence; no compiler, application launch, GUI action or Gitea mutation was performed. This review file is the only reviewer-created artifact.
+
+## Exact package and integrity
+
+Reviewed `ArcadiaStudio-0.2.0-preview.compact-help.20261001-x86_64-pc-windows-gnullvm.zip`: 34,184,534 bytes, SHA256 `18af75c7aea60bb0d5db5b1925d0d0815ecd08afc5bb258438851cfda809a6f2`.
+
+Independent checks verified all 565 ZIP entries against extracted bytes, the exact extracted file set, 564 SHA256SUMS entries and all 559 package input hashes. Archive names have no absolute/traversal paths, backslash ambiguity, colon paths or case-insensitive duplicates. Package BuildEvidence equals the supplied evidence file. Independent PE parsing reproduces all three recorded import lists and finds no delay-import directory. Dynamic runtime behavior remains a separate check.
+
+Provenance correctly distinguishes desktop source `6e7c4ddaf0775198384a8c4882809ea8e14b2976`, reused server source `715036e132677dd2bc2fb37ed316d93dc9987aec`, and package documentation source `ea23e229260d7d050b3c3b88e77c3a851e936abe`. It identifies Rust 1.98.1, gnullvm and dev/unoptimized profile. Executable hashes match the recorded final desktop (`d55ecad4...`) and released server (`6cebacc1...`). The source comparison has no core, server, Cargo or vendor dependency changes; the documentation commit changes only acceptance evidence. These are checked provenance records, not an independent rebuild.
+
+## Runtime, notices and documentation
+
+The selected DLL is `f45604a12e8bcd839fd86f667c1be1cc7c4f9da2b3c69ff381ac708f0e1ae7d4`, matching the final desktop runtime and the selected LLVM-MinGW 20260826 x86_64 toolchain. Its packaged distribution LICENSE matches that toolchain exactly. The component notice matches the reviewed manifest's DLL-bound entry and exact LLVM commit `ea7d852a70e8bdfaf601d6626a760f9771b2c4b4`; distribution build correspondence remains the stated external provenance limitation.
+
+All 489 referenced notice hashes pass. The 268 dependency package identities, registry checksums, features and local source-hash inventories agree with the accepted donor inventory except for intended `oa-desktop` source changes. Rust notice/target-library inventory is identical. Cargo.lock and all seven shared workspace-input hashes match the checkout. This is notice/inventory verification, not a universal license or binary asset audit.
+
+All 66 collected source documentation/example/deployment/license files match the checkout. The package document checker resolves all 18 local links. Built-in Help execution is outside this static check.
+
+## Fresh server pairing evidence
+
+The donor server's old packaged runtime was `aa282fa4...`; its historical runtime acceptance does not establish the new pairing. The fresh smoke pins the server and `f45604a1...` DLL, uses the newly extracted package, an unrelated working directory, a fresh store, loopback port 54695, and a system-only child PATH. Both process command lines point to this extracted server.
+
+The reviewer compared the adapted harness with the prior accepted harness and independently checked all 11 captured HTTP request/response pairs. The 23-check result is supported: readiness; exact packaged OpenAPI; source import and readback; stable model IDs distinct from resource identity; CRLF and comment preservation; a name-only complete-model change from revision 1 to 2; changed ETag; stale If-Match refusal with 412/revision_conflict; unchanged accepted model/source after refusal; exact committed envelope; and identical envelope, source, ETag and stored bytes after restart. The store hash is `62d1fed82f4fc793f3173beb8693fbde94d6aabf4e38e161da93b59178969ee2`. Logs contain only expected startup messages; stdout is empty.
+
+The first run contains a harness-only fixture encoding error: adaptation changed the old em dash comment to the literal mojibake text `—` (U+00E2, U+20AC, U+201D). Its exact current UTF-8 input/output comparison remains valid, but it did not exercise the intended em dash. The original run and its bytes remain preserved.
+
+The parent then ran `server-smoke-unicode02` with a fresh store and processes. Independent script comparison shows only the fixture comment changed to U+2014; runtime pins and behavioral assertions are unchanged. The reviewer independently reconciled this run's 11 captured HTTP exchanges, exact original/edited source bytes and CRLF, complete model delta, revision 1 to 2, ETags, 412 refusal, stored envelope and exact restart readback. All checks agree with its 23-check PASS result. The corrected source contains exactly one non-ASCII codepoint, U+2014. The new resource is `53a28b61-1736-4bc4-8553-28995488647f`; its revision-1 and revision-2 ETags match that resource. The package ZIP remains unchanged.
+
+| Evidence | First run (`server-smoke`) | Corrected run (`server-smoke-unicode02`) |
+| --- | --- | --- |
+| `run.py` SHA256 | `41d25f1d63b32737859674f414470c06868948db60f29a63eb5ac6b6857addb3` | `20344608a0623584a0e0ac66dc7f435a0de053d39b4254e92f1c1148aed8e8b9` |

+
+Each run's two owned server processes were stopped with Windows TerminateProcess after acknowledged requests, producing exit code 1. This supports restart persistence of acknowledged writes, not graceful shutdown, in-flight-write recovery or power-loss safety. Authentication, remote/TLS behavior, concurrency/load and wider API semantics were not exercised.
+
+## Acceptance boundary
+
+Fresh packaged desktop edit/save/undo/redo/reopen and contextual Help checks remain owned by the native reviewer. Publish their actual results separately. Retain development-preview limitations, the distinction between final focused checks and inherited full-suite evidence, and the outstanding complete-project requirements. Existing published assets remain unchanged.
