+### Delivered
+
+- Split the public landing foundation from the lazy workbench and MapLibre
+  styles. The initial production CSS payload dropped from roughly 219 kB to
+  38.38 kB while the authenticated workbench keeps its complete styling.
+- Extended the reproducible browser audit to cover the landing and workbench at
+  390 x 844, 1366 x 768 and 2560 x 1080, including mobile navigation,
+  keyboard tabs, loading state, advanced map flow and every guest workspace.
+- Corrected the smartphone shell hierarchy: topbar, guest banner and page
+  heading no longer overlap, and the live Selecteer/Bronnen/Verwerk/Controleer
+  rail now sits below the map actions instead of behind the fixed navigation.
+- Kept full workspace titles for headings and accessible names while shortening
+  the two mobile navigation labels to `AI-beeld` and `Export`; the browser gate
+  now rejects any visible sidebar label whose text box is clipped.
+- Made map-analysis failures outrank empty states and added an explicit retry;
+  new selections clear stale coverage immediately.
+- Replaced synchronous browser inference with governed async detection and
+  segmentation queues, project-bound job polling and persisted-run
+  reconciliation. Detection has NVIDIA preflight; segmentation now fails
+  closed under the same server CUDA contract. Zero-result runs are communicated
+  without claiming that the AOI is object-free.
+- Bound guest detection, segmentation and export reads/writes to the signed
+  demo project at the resource level. Matching query parameters can no longer
+  authorize another project's run, dataset, result or download.
+- Closed stale-response races in temporal comparison and the local GeoAI
+  assistant, plus detection/segmentation run, result and QA flows across project
+  switches. Previously visited workspaces no longer reload together after every
+  navigation change.
+- Added keyboard-complete pipeline tabs and React-driven model-dialog state,
+  initial focus and trigger-focus restoration. Landing scrolling now respects
+  `prefers-reduced-motion`.
+- Hardened outbound acquisition redirects before the redirected request is
+  opened, including origin/port and embedded-credential rejection, and fixed
+  bounded pagination for segmentation result lists.
+- Fixed segmentation readiness and section status: configured production
+  models now require a real tile manifest before queueing, fixture mode is
+  visibly test-only, and queued/running NVIDIA work has an explicit live state.
+- Localised known model registrations and availability states in the Dutch UI;
+  raw English backend placeholder copy no longer leaks into the primary model
+  selector or readiness guidance.
+
+### Verification
+
+- Frontend TypeScript check and production build passed.
+- Complete frontend suite: 36 files / 151 tests passed.
+- Relevant backend release set: 121 tests passed, covering async analysis jobs,
+  atomic claims, guest/resource isolation, redirect policy, segmentation
+  pagination, NVIDIA runtime enforcement and current AI-lab contracts.
+- Ruff passed over every changed backend Python module and test.
+- Browser evidence passed across three landing and three authenticated
+  workbench viewports with zero horizontal overflow, console errors or failed
+  API requests in `.codex-artifacts/sol-ultra-final-l/manifest.json`; focused
+  AI-workspace and segmentation screenshots are stored beside it.
+- Production build passed. Initial landing CSS remains 38.38 kB (8.22 kB
+  gzip); the lazy workbench JS is 479.76 kB (129.25 kB gzip) and MapLibre stays
+  isolated in its own lazy chunk.
+
+### Boundaries
+
+- This pass improves runtime correctness and presentation; it does not invent a
+  new accuracy claim or promote a model checkpoint. Existing governed model
+  evidence and regional release gates remain authoritative.
+- Physical touch-device and screen-reader certification remain human QA. No
+  commit or deployment was performed because the active execution brief
+  explicitly forbids committing unless requested.
