+# Guarded label cue: not promoted
+
+Candidate B is not accepted for production. Exact source `3e5e094bb17877674f4f3ea027a25fc0bdecdfe7`
+passes formatting, all 87 selected diagram tests, strict desktop/all-target Clippy
+and the matching Windows GUI build. The initial independent source review preceded
+formatting and strengthened clearance/invalidation controls; production geometry
+policy stayed unchanged. Its original hashes and scope are retained in
+[source-review.md](source-review.md), rather than relabeled as a review of new bytes.
+
+The [fresh native reader](evidence/native-cue/first-reading/review.md) sees only the
+complete target scene before locking answers. Initial participants are correct,
+but the conversation still has plausible foreign Allocation ownership and the
+pale cue cannot be used confidently at Fit52% or one zoom step. Request/report
+tracing remains uncertain. This fails the predeclared reliable-association/no-
+explanation gate. Correct guesses alone do not establish an intuitive workflow.
+The separately published [baseline fresh static review](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/src/commit/45bfb63b4fb90683c7ed769565698f04f808a36a/harness/experiments/diagram-readability-20261001/first-exposure/review.md)
+assigns the conversation to that
+Allocation and its arrowhead, but different readers and static/live conditions
+prevent a causal effect estimate or human-study claim.
+
+The existing-path 18-world-unit dotted cue changes neither model nor routing.
+Native candidate and released-baseline SVG exports both succeed. The
+[complete byte comparison](evidence/native-cue/svg-comparison-final.json) finds
+one nonsemantic cue path; removing exactly that path makes the entire SVG
+byte-identical to baseline, including every original drawing mark, label and
+metadata. Both complete 138,661-byte input models stay exact, both desktop
+processes close normally with exit0 and empty streams, and executable/runtime
+pins remain unchanged. This is conservation evidence, not repaired reading.
+
+Experimental desktop SHA256: `38abdb21278f85b6d4f946d25535c084aa49eddfac74e99f78caa85ace1faa04`.
+Baseline desktop: `d55ecad4b0f75c0c9c26625e5441bef9c9360890b65bc13236c6ebfaf03d631e`
+from source `6e7c4ddaf0775198384a8c4882809ea8e14b2976`. Both use runtime
+`f45604a12e8bcd839fd86f667c1be1cc7c4f9da2b3c69ff381ac708f0e1ae7d4` and fixture
+`9db1015369f450d5810c96a01fddb8a009d57f6aafbda5182703f15ded23d9c8`.
+
+The [byte-preserved packet](evidence/evidence-files.json) includes raw screenshots,
+locked/continued reading, setup/export reports, input models and actual SVGs,
+launch/exit receipts, empty streams, scripts, gate logs and source identities.
+Historical scripts retain absolute paths; adapt to a fresh isolated trial. Do not
+overwrite prior receipts. B's first launcher stopped before process creation
+because Windows manifest keys used backslashes; the corrected launcher normalizes
+keys while preserving the original manifest. Baseline chooser's first typing
+attempt left its field empty; explicit pointer focus/native path retry succeeds.
+These tool/harness limitations are not recorded as product defects.
+
+The first SVG checker used a regex-byte membership predicate that did not itself
+prove baseline cue absence. Full cue-removal byte equality already passed; the
+final checker adds the direct literal absence assertion, retains the initial
+checker/receipt, and passes again against unchanged actual exports.
+
+Reproduce code gates from the source checkout with Rust configured:
+
+```powershell
+cargo fmt --all -- --check
+cargo test --locked -p oa-desktop -- diagram:: --test-threads=1
+cargo clippy --locked -p oa-desktop --all-targets -- -D warnings
+cargo build --locked -p oa-desktop --bin arcadia-studio
+```
+
+Build is a development Windows gnullvm executable; no packaged release, Linux,
+full-suite or full OA/SA acceptance is claimed. Dense rebuild/preview timing,
+general collision geometry, accessibility/DPI and edited-label persistence were
+not pursued after the first-reading falsifier. No weight/contrast tuning around
+this scene is accepted. The next materially different experiment tests measured
+wrapped labels and placement, with an explicit unresolved authored-format boundary.
+The permanent Properties pane and narrow canvas remain separate workspace costs;
+the native chevron expands tools rather than recovering Inspector space.
+
+[Independent final evidence review](final-evidence-review.md) reconciles the complete packet and the failed-reading conclusion.

+Opened C:/ar-label-cue-01a0d717/.local/native-cue-baseline/working/eight-card.json with native Open. Initial Ctrl+A/type on apparent filename focus left the field empty; no Open was committed. Explicit pointer focus and one literal backslash-path retry displayed the exact intended path, then pointer Open loaded it.

+# Native label-cue scene preparation
+
+Scope: scene preparation only, before a separate fresh reader's first native inspection. Parent owns build identification, launch, fixture byte checks, and process logs. No GUI input or launch until exact parent readiness. Source branch inspected: `codex/label-cue-experiment-01a0d717-20261001`; clean tracked working tree at planning time.
+
+1. On parent readiness, enumerate native windows and identify only the parent-launched experimental executable. Observe before each UI action using the Computer Use skill.
+2. Open `C:/ar-label-cue-01a0d717/.local/native-cue/working/eight-card.json` through the native chooser. Focus the filename field and use Ctrl+A, literal typing, and actual Open/Return commit; do not use accessibility set_value.
+3. In Architecture, switch to System perspective and choose the saved `Issue 38 representative eight-card mixed view`, then the Traceability projection. Resolve controls from actual screenshots. Do not expose intermediate OA or simpler SA views to the fresh reader.
+4. Set normal 1440×900 client size (approximately 1442×932 outer screenshot), use Fit, and Escape to zero selection. Leave the target fully visible with no menu, Help, dialog, or element inspector overlay obstructing it. Do not edit, Apply, Save, drag, or infer relationship answers.
+5. Save only the final target screenshot plus preparation report under `.local/native-cue/prep`. Record exact observed window size, zoom, header, zero selection, and visible card count. Record setup facts without decoding or naming diagram relationships for the reader.
+6. Stop all GUI input and relinquish to the parent/new reader. The fresh reader's first view must be this complete target scene. Parent should give them no earlier source/geometry/results or preparation intermediate screenshots. Parent verifies pristine bytes independently.
+
+If the target cannot be reached or the expected scene does not appear, stop and report the actual setup mismatch without editing or supplying inferred answers. No compilation, Gitea action, production edit, fixture generation, or app launch by this preparer.

+# Independent first-exposure native diagram reading
+
+## Phase 1: locked first reading, before any viewing input
+
+Evaluator: candidate_blind_reading, GPT-6 Astra agent. Date: 2026-10-01. This is one fresh agent trial, not a human study or native editing acceptance.
+
+Window: returned window 8979690, prepared native arcadia-studio.exe. The first live screenshot shows Architecture, System, saved view `Issue 38 representative eight-card mixed view`, view content `OA → SA traceability`, 52%, 0 selected, and all eight cards. Capture size: 1442 × 932. Evidence: [raw first Fit capture](01-first-fit.png).
+
+No UI input, zoom, selection, Inspector/Connections interaction, semantic lookup, model/source reading, oracle, previous report, or comparison was used before this record. The existing Properties panel is visible in the complete screenshot; its text was not used to infer relations. Only the working agreement and Computer Use operating documentation were read.
+
+| Displayed relation | First endpoint/card interpretation | Orientation | Confidence | Visible stroke/marker evidence and alternatives |
+| --- | --- | --- | --- | --- |
+| Request field repair | Assess pressure alarm to Repair valve in the field | Directed, left card toward repair card | Low to moderate, about 0.45 | The assessment card has a rightward green outlined triangle at its right edge; the repair card has a rightward triangle at its upper left edge. A thin orthogonal route and this label occupy the middle area, but I cannot confidently follow the label's entire route through the crossings at Fit. A plausible alternative is that the labelled route begins at Assess an alarm procedure or at the Pressure coordination service; another is that the triangles belong to neighboring relations. The chosen pair is partly aided by the meaning of the name, not established solely by an unambiguous stroke trace. |
+| Report repair result | Repair valve in the field to Confirm safe pressure | Directed, from repair leftward and down to confirmation | Moderate, about 0.60 | The label sits just above a horizontal line leaving the lower left of the repair card. A leftward outlined green triangle appears there, and a leftward triangle enters the right edge of Confirm safe pressure. The vertical path through the left-middle network is hard to disambiguate. Reset valve remotely is a plausible alternative target because a left-facing marker also enters that card; the line might instead attach to the Pressure coordination service. The name helps the repair-to-confirmation interpretation. |
+| Technician service conversation | Field technician and Pressure coordination service | Tentatively unoriented, not confidently bidirectional | Moderate for endpoints, about 0.65; low to moderate for orientation, about 0.45 | Purple and blue outlined square markers appear at Field technician's left edge and Pressure coordination service's right edge, with an orthogonal route between their vicinity. I read squares as connection endpoints without directional arrowheads. The label lies lower and nearer a separate down-going route from technician toward Repair valve in the field; therefore technician-to-repair, directed downward, is a credible alternative. I cannot confidently associate this label to one of those nearby routes at this size. |
+
+### Immediate first-view reading observations
+
+The labels are very small at 52%. The cards and broad routing are visible, but several central horizontal segments cross or share near-parallel vertical paths. Following a named line requires sustained tracing. The triangle and square shapes look potentially semantic; I have no legend establishing their meaning. They could also be connection affordances or ports rather than the relation's orientation. I did not treat them as editing handles with certainty. No obvious branch junction cue can be read reliably in this first view. These observations are locked before additional viewing input; later discoveries must be separate.
+
+## Phase 2: bounded viewing after first-answer checkpoint
+
+The first-answer checkpoint was sent to the parent before any input. I then refreshed the live native window, clicked Zoom + once (52% to 62%), observed and preserved [the raw 62% capture](02-zoom-62.png), refreshed again, clicked Fit, and verified [the restored raw 52% capture](03-restored-fit.png). These were the only two UI input actions. No card, link, label, model, view, property, connection, filter, or selection was clicked. No pan, drag, edit, Apply, Save, or semantic lookup was performed.
+
+At 62%, the card titles and labels were slightly larger but several rightmost cards and the conversation label were clipped, and Confirm safe pressure was partly clipped at the bottom. This traded overall route context for only a small readability improvement. I stopped after that one step instead of gathering a partially visible enlarged route as if it established the answer.
+
+The subsequent view did not establish a confident replacement for any locked first answer. In particular, the Request field repair label lies above a long horizontal stroke with upward and downward routing in a crowded area. Following it can suggest other cards than my initial pair; I cannot resolve the crossing versus branch associations from this bounded reading. Report repair result remains my most plausible first reading, but shared-looking vertical routes also approach Reset valve remotely. Technician service conversation remains uncertain because its text sits near the down-going technician-to-repair arrow as well as the square-ended technician/service route.
+
+The pale stroke-like marks adjacent to some label text were not independently clear enough for me to use as semantic leaders. They could be subtle connector fragments or label attachment cues; I cannot reliably distinguish them from low-contrast visual noise at these scales. The colored endpoint shapes are more conspicuous, but without a visible legend their port/arrow/handle role is uncertain. This is a drawing-only readability finding, not proof of incorrect model semantics or an assertion that any particular marker is nonsemantic.
+
+## Handoff and limits
+
+The same native app remains open. Final observed state: Architecture, System, `Issue 38 representative eight-card mixed view`, `OA → SA traceability`, Fit 52%, 0 selected, all eight cards visible, 1442 × 932. GUI control is relinquished to the parent. The initial answers above remain locked for oracle adjudication. No source, model JSON, answer key, old report, research, or baseline comparison was inspected. This bounded agent trial measures first-exposure reading uncertainty and the cost of tracing these particular routes; it does not establish human usability, correctness, editing acceptance, or generalization beyond this scene.

+# Independent B falsification and evidence checkpoint review
+
+No material blocker remains for preserving this failed experiment. Candidate B remains NOT promoted. This review accepts the bounded evidence/claim reconciliation, not production rendering, editing/persistence, performance, release or generalized usability.
+
+Reviewed source identity `3e5e094bb17877674f4f3ea027a25fc0bdecdfe7`, packet README/STATE, original scoped source review, actual first-reading and setup/export reports, both helpers and retained corrections, captured SVGs/input models/process receipts, gate logs, commands and source manifest. No compiler, GUI, Gitea, commit or source/document patch; this review file is the only new artifact.
+
+## Independently reconciled integrity
+
+All 43 evidence inventory entries match working-file sizes and SHA256. Only evidence-files.json itself is unlisted. At the final read, all 43 staged Git blobs also match the inventory exactly. The four source-manifest file entries match Git blobs at 3e5e094b. Relevant relative README/first-reading links resolve.

+Actual copied and local SVG bytes agree. Candidate SVG is 7,391 bytes, SHA256 `ada19523bb65734ee636003f5db0f49755159b0239449050c4284b9212be1060`; baseline SVG is 7,209 bytes, SHA256 `645ee69cc97d11acc812539b62528d7fdceec32aa2516d4ade8508016164119d`. Independently parsed exactly one added path for edge `63009b5f-539e-5914-b630-ec6b7fefb4d5`, M1180 274.5 to L1162 274.5, no fill, #4b5968 stroke, width1, dash2/3, pointer-events none and no semantic edge/arrow marker. Baseline literally contains no data-label-cue attribute. Removing that exact candidate path makes the entire SVG byte-identical to baseline, not just selected geometry fields.
+
+Both actual input models and copied packet models are 138,661 bytes with unchanged SHA256 `9db1015369f450d5810c96a01fddb8a009d57f6aafbda5182703f15ded23d9c8`. Actual candidate/baseline executable hashes match their receipts (`38abdb21...` / `d55ecad4...`); both DLLs match `f45604a1...`. Candidate PID2600 and baseline PID10220 each have normal exit0 receipts and genuinely empty stdout/stderr files. These are no-edit fixture/export conservation checks, not source Save, edited-label persistence or model migration acceptance.
+
+## Claim reconciliation
+
+The test log supports 87 passes, zero failures/ignores and 1,463 filtered out. Commands.json explicitly attributes formatting, strict desktop/all-target Clippy and GUI build flags to parent-observed invocations; logs record successful completion. No full-suite claim is made. The earlier source review's preformat/pre-strengthened-test hashes remain historical and are not misrepresented as exact final-source review.
+
+The candidate first-reading report supports the stated rejection: the fresh agent gave correct initial participant guesses but retained technician-to-repair Allocation as a credible conversation-label alternative; it could not confidently use the pale marks at Fit or one zoom step. Request/report tracing remained uncertain. Setup was performed separately and the reader reports locked answers before interaction or semantic lookup. The packet does not turn this one-agent trial into human-study evidence or prove causal improvement relative to a different static reader.
+
+Initially README's auxiliary baseline static-reading comparison lacked its source. Parent added a direct commit-specific link to `45bfb63b.../first-exposure/review.md`; that local authoritative report indeed assigns the conversation to the technician-to-repair Allocation/arrowhead and disclaims human/generalized acceptance. The traceability finding is resolved. This reviewer did not query Gitea or independently certify remote availability.
+
+README and STATE clearly say B is not accepted and must not be treated as an integrated release. Stopping before dense-preview timing and edited-label persistence is reasonable after the predeclared first-reading falsifier; those tests are expressly unperformed, not assumed to pass. Passing compilation/conservation does not repair this failed association result. Future multiline/layout work remains a separate experiment with an unresolved authored-format boundary.
+
+## Retained harness limitations
+
+The original launcher used forward-slash dictionary keys against a Windows manifest containing backslashes. Its receipt construction precedes stdout creation/Popen, consistent with failure before process creation. Corrected code normalizes keys without altering the original manifest. The original SVG checker tested literal regex bytes for baseline membership, which was insufficient. Its whole-output equality check was already meaningful; the final checker adds literal data-label-cue absence. Both scripts and receipts remain preserved, and the independent direct comparison above confirms the corrected result.
+
+Copied scripts retain their original filesystem assumptions and need adapted roots in a new checkout, as README states. No generic portability or hardened evaluator claim is appropriate. No source mutation, semantic contradiction, hidden cue promotion or unsupported persistence acceptance was found. Publication of this experiment checkpoint remains separate; no new tag, release or published asset is certified here.
