+# Nightdrive sign corridor follow-up
+
+Status date: 2026-09-03
+
+This bounded follow-up corrects two rendered regressions without changing the portfolio content layer or the established sign lifecycle. The supplied captures showed the Experience sign under the left-side Experience card and the navigator sign at only phone-scale on a 692×793 viewport.
+
+## Implemented contract
+
+- Experience now owns the right roadside corridor. A wide navigator arrival uses the established right dwell pose beside the left Experience card.
+- During passive Profile-to-Experience travel, both the outgoing right Profile panel and incoming left Experience panel are visible. Stable lower/nearer right-side poses for wide and short-landscape projections keep the complete face clear of both panels instead of merely changing corridor metadata.
+- Tall navigator arrivals preserve the existing pose through 480px viewport width. From 480px to 720px, scale and mounting height interpolate with a smoothstep curve from `0.25 / y 3.0` to `0.44 / y 4.5`, then remain capped. The larger sign therefore stays in the world-visible slot between stacked content panels rather than growing underneath one.
+- Width changes use the existing 320ms responsive reflow. They do not relatch a target, redraw a visible label, duplicate a lifecycle, or allocate geometry, material, or texture resources.
+- Candidacy, navigation idempotency, 1,400ms minimum dwell, pass-by departure, phone composition, quality behavior, and motion suppression are unchanged.
+
+## Measured projection
+
+The authenticated browser instrumentation and an independent production-preview capture agreed on the corrected geometry. Full values are in [`measurements.json`](measurements.json).
+
+| Scenario | Sign face bounds | Nearby content | Minimum measured separation |
+| --- | --- | --- | ---: |
+| 692×793 Profile navigator | 151.56–299.37 × 538.49–579.23; 147.82px wide | Profile bottom 518.38; Experience top 614.38 | 20.12px |
+| 1440×900 passive Experience | 1032.44–1276.55 × 556.44–619.16; 244.11px wide | Profile bottom 536.28; Experience top 680.28 | 20.16px |
+| 844×390 passive Experience | 640.50–780.92 × 231.91–266.39; 140.42px wide | Profile bottom 194.41; Experience right 540.14 | 37.50px vertical / 100.36px horizontal |
+
+Both scenarios exceed the existing 16px opaque-content separation contract. The 692px sign was 88.68px wide before the responsive correction in the deterministic renderer test. The ≤480px branch retains the previous phone pose exactly.
+
+The complete browser matrix also exposed a 3px Profile-panel graze at 844×390 after Experience moved right. The short-landscape pose was brought lower and nearer, then verified in an isolated authenticated production-camera flow at 844×390. A dedicated browser regression now covers that exact transition without depending on every earlier route in the larger sequential matrix. No safety margin, timeout, or lifecycle assertion was relaxed.

+- Supplied undersized 692×793 navigator: [`before/medium-navigator-too-small.png`](before/medium-navigator-too-small.png)
+- Corrected 692×793 Profile navigator: [`after/profile-navigator-692x793.png`](after/profile-navigator-692x793.png)
+- Corrected Experience navigator arrival: [`after/experience-navigation-right-1440x900.png`](after/experience-navigation-right-1440x900.png)
+- Corrected passive Profile-to-Experience transition: [`after/experience-passive-right-1440x900.png`](after/experience-passive-right-1440x900.png)
+- Corrected short-landscape passive transition: [`after/experience-passive-right-844x390.png`](after/experience-passive-right-844x390.png)
+
+## Verification record
+
+- The production gate passed type checking, 43 unit files / 567 tests, client and SSR builds, prerender validation, and transfer budgets.
+- The focused sign-controller/world run passed 79 tests in 2 files. The browser specification compiles and discovers the dedicated 692×793 and 844×390 regressions.
+- The unchanged pass-by departure browser check passed with one worker in 6.3 seconds of test time. The isolated authenticated 692×793, 1440×900, and 844×390 flows produced the measurements and full-resolution captures above with `fontReadyWhenDrawn: true`.
+- The final privileged full-matrix and authenticated-allocation launches could not start because the host approval service returned HTTP 404 before execution. A restricted retry was invalid because Chromium terminated at launch with `sandbox_host_linux ... Operation not permitted`; none of those instant launch failures are represented as portfolio failures or passes.
+- The patch creates no geometry, material, texture, render-target, or scene-graph objects. The most recent authenticated High-tier sign-system trace therefore remains the applicable allocation baseline: 5,608,790 texture bytes, 755,916 geometry bytes, 161,344,784 render-target bytes, a 33,554,432-byte allowance, and 201,263,922 total accounted bytes. The current transfer-only gate reported no violations.
+- Deployment verification remains outside this sign fix: 5/9 checks passed in the restricted run, two security-evidence checks stopped at the repository's expired evidence timestamp, and two HTTP-fixture checks could not bind localhost in the sandbox. No assertion, timeout, security timestamp, or budget was changed.
+
+## Ownership
+
+No Blender work or new asset was justified. The authored finite car remains Blender-owned and unchanged. Dynamic text, sign behavior, responsive placement, road, terrain, atmosphere, sun, camera, and motion remain Three.js-owned.
