+# Processing-monitor translation fallbacks — 2 November 2026
+
+CONFIRMED functional defect: runtime status/stage/task/event/worker names matching inherited Object properties bypassed existing unknown-value fallbacks. Six EN/Bokmål cases using constructor, toString and __proto__ failed before the fix. No prototype mutation, privilege escalation or backend validation bypass is asserted.
+
+Minimal shared fix: the five existing label dictionaries now use null-prototype objects, retaining their exact entries and Record typing. All callers, Object.keys filter controls and existing fallback expressions remain intact. No auth/role, API, polling, account-isolation, queue, model or production behavior changed. Known fields translate normally; unknown names reach the existing localized Unknown/Other operation/Unregistered worker/Not recorded labels.
+
+PASSED: all 17 admin-processing-page tests, zero failures/pending, native exit 0. Six new cases exercise all five map domains, open the collapsed worker-details section, then check timeline event/status/stage fallbacks; eleven existing cases cover normal monitor workflows and safety. An intermediate rerun failed only because the new worker-label visibility assertion inspected a closed details element; the test now opens its summary through the normal UI. That run is not counted as passing or added to the final total.
+
+PASSED: full typecheck and scoped two-file ESLint, native exits 0. Thirty-eight distinct map/fallback keys asserted present in both catalogues. Local native report: job-tracker-ui/.artifacts/processing-label-fallbacks.json. AST-only graph update required after code edits; keep generated graph separate from the implementation commit. Full build/browser and final integrated security acceptance are not claimed for this patch.
+
+Five historical call sites resolved: AdminProcessingPage.tsx:130/131/175/191/212. Machine register binds each expression and reviewed source hash: 131 resolved / 57 pending of 188. The earlier safe map iterators retain their coverage with updated source hashes. This is key-domain/fallback evidence, not complete locale or native-language acceptance.
+
+Rollback: revert the five dictionary constructions and six regression cases; no data migration or restoration needed. Continue remaining owner-map review; preserve unapproved final design and live/security/release gates.
