+# Task 02: Align Inbox feature-toggle terminology
+
+## Summary
+
+Align the runtime feature-toggle label and public configuration reference with
+the Inbox destination name. Keep the runtime flag identity and behavior unchanged.
+
+## Acceptance
+
+- The Feature Toggles page shows `Inbox` for `features.needsYouInbox`.
+- The label matches the Inbox destination copy contract outside the Office-mode
+  collision case described by D4.
+- The key, environment variable, route, defaults, persistence, restart behavior,
+  and effective feature value remain unchanged.
+- The public configuration reference uses `Inbox`.
+- The registry test pins the display label and its existing metadata.
+
+## Verification
+
+- `go test -tags fts5 ./internal/runtimeflags/...` passed.
+- `node --test .github/scripts/pr-docs.test.cjs` passed: 52 tests.
+- The local documentation coverage evaluator reported `status: covered` with no
+  errors for the changed runtime file and this delivery package.
+- `node --test scripts/validate-public-docs.test.mjs` passed: 62 tests.
+- `node scripts/validate-public-docs.mjs` passed: 46 published docs pages.
+- `git diff --check` passed.
+
+## Files
+
+- `apps/backend/internal/runtimeflags/registry.go`
+- `apps/backend/internal/runtimeflags/registry_test.go`
+- `docs/public/configuration.md`
+
+## Results
+
+The registry label is `Inbox`. The metadata test protects the label and stable
+runtime-flag metadata. The public configuration reference matches the label.
+No runtime behavior or route identity changed.
