+## 2026-07-18 - Belgium/North Sea RC-8 release journey automation
+
+Implemented:
+
+- Added four Vitest suites with 12 executable tests for map selection,
+  coverage resolution, temporal comparison and bootstrap state.
+- Added a dry-run-first golden-area operator. It reuses Mol/Kempen and creates
+  only missing bounded Wallonia, Brussels, language-boundary, coast and
+  offshore Areas through canonical APIs, with deterministic geometry hashes.
+- Added a Playwright release runner and shell wrapper covering every golden
+  area, governed Mol metrics/provenance, compatible forest history, no-data,
+  partial coverage, unsupported maritime metrics, simulated provider failure,
+  persisted map export, real local Ollama context and explicit configured
+  local YOLO execution.
+- Fixed explicit demo seeding so its archived technical project is reactivated
+  before reuse. A direct service regression protects this lifecycle behavior.
+- Added the frontend tests and static E2E/script checks to readiness and copied
+  the golden-area operator into the all-in-one image.
+
+Validation:
+
+- Repository readiness passed backend compilation, 1,012 backend tests, four
+  frontend test files with 12 tests, frontend typecheck/build and Alembic head
+  `202607160001`.
+- The live runner completed all Belgium/North Sea journeys against PostGIS
+  3.6. It persisted an export, received a grounded Ollama answer and completed
+  configured local YOLO execution through Job and AnalysisRun persistence.
+- The successful evidence manifest reports no unexpected browser-console or
+  failed-request events. Re-running the area operator created zero duplicate
+  Areas and retained seven unique geometry fingerprints.
+
+Decision:
+
+- RC-8 is complete. RC-9 loading, accessibility and performance hardening is
+  active.
