Phase 6, step 3. The app had no navigation component of any kind: 43 screens reached by pushing a route, and one home screen whose top app bar carried the only two peer surfaces -- a profile avatar in the leading slot, a search icon in the trailing one. **This is an information-architecture change and was taken as one.** With a single top-level destination, a navigation bar would have held one item and been strictly worse than the app bar it replaced -- M3's caution is to swap only functionally equivalent components. Promoting search and profile to peer destinations is what makes a navigation component mean anything here, and it was put to the product owner rather than inferred. Answered: promote them. The consequence is in `HomeScreen`: the app bar now carries a title and nothing else. Two routes to one destination is the thing the caution is about, and the navigation component is now the one route, at every breakpoint. **Which component, at which breakpoint**, straight from the layout foundation: | compact | navigation bar | | medium, expanded | collapsed rail | | large, extra-large | expanded rail | `NavigationSuiteScaffoldDefaults.navigationSuiteType` is not used, and the difference is the last row -- it stops at the collapsed rail, because it classifies with the three-value window size class rather than the five breakpoints the May 2026 revision published. Deriving from `Breakpoint` reaches the row the library's default cannot, and keeps one source of truth for window width in the app. `NavigationSuiteType.None` on everything else. A navigation bar belongs on the destinations it switches between; on a chat room, a signing screen or an onboarding step -- pushed to and left by coming back -- it is a permanent invitation to lose your place. **Two things the wiring needed.** `ActiveProfileRoute` is addressed by metadata event id, not by public key, and only the home screen ever had one. The nav host now observes it for as long as a key is signed in, and the profile item is *disabled* until it arrives rather than absent -- an item that appears late moves the two beside it, and a bar whose items move under a thumb is worse than one briefly unavailable. The item click pops to `HomeRoute`, not to the graph's start destination. The android docs give the second shape and it would be wrong here: this graph starts at `LoadingRoute`, and onboarding clears the stack with `popUpTo(0)` on its way to home, so by the time these items exist the start destination is not on the stack at all -- popping to it would leave the loading screen underneath as the thing back returns to. **Tests, and one that could not be written.** The breakpoint-to-component table is a pure function so all five rows are asserted; the two rail rows differ only in whether labels are drawn, and nobody opens a 1200dp window on purpose. Four more compose the component around a real nav graph, because `TopLevelDestination.of` matches by `hasRoute` -- reflection over the serialized route -- and a renamed route would fail by never showing the component at all. Navigation in those is driven through the controller rather than by tapping an item. That is a harness limitation, established rather than assumed: a click handler that navigates trips navigation-compose's own main-thread assertion under `runDesktopComposeUiTest`, reproducible in twenty lines containing no app code -- a `NavHost`, two routes and a `TextButton`. What an item's `onClick` builds is asserted where it is a pure function instead. Also `material3-adaptive-navigation-suite`, versioned with material3 rather than with the adaptive library: it is published by the material3 group, and its 1.10.0-alpha05 is what names adaptive 1.2.0 in the first place. Most of the `MantraNavHost` diff is indentation -- the `NavHost` call gained an enclosing composable. `git diff -w` shows the 38 lines that are not. 626 jvm tests green; android compiles.
