Wires the phase's shared architecture end to end through one main tab
(Marketplace, the worst-measured revisit per 02-FINDINGS.md):
- keepAliveRoutes.ts: exact-match route classifier (shouldKeepAlive,
KEEP_ALIVE_PATHS, KEEP_ALIVE_MAX=6), seeded with only the tracer tab's
path. Deliberately not KeepAlive `include` name-matching (async
components under `<script setup>` have no inferable name).
- DashboardRouterView.vue: extracts Dashboard.vue's nested RouterView into
a host where <KeepAlive> is a permanent element (never torn down by
v-if) with its child conditionally present via shouldKeepAlive(route);
a sibling Transition renders non-cached routes. Both original wrapper
shapes (full-bleed chat/mesh vs. padded/scrollable default) are
preserved via computed helpers on one stable, unkeyed wrapper div; the
:key moves onto <component> itself. Adds per-route scroll retention
since the scroll container is now stable across navigations.
- useCachedResource.ts: registers onActivated(() => refreshIfStale())
alongside the existing onScopeDispose block, closing the gap where a
kept-alive tab would otherwise never revalidate on reactivation
(onScopeDispose doesn't fire on deactivate; window focus doesn't fire
on an in-SPA tab switch). No-ops safely for all 8 existing consumers
outside a KeepAlive boundary.
- useRouteTransitions.ts: exports TAB_ORDER so 02-04 can widen
KEEP_ALIVE_PATHS from the same source of truth.
- Dashboard.vue: renders DashboardRouterView in place of the inline
block; removes the now-superseded detail-route scroll save/restore
(querySelector target no longer exists post-restructure — the new
per-route Map in DashboardRouterView.vue is a strict superset).
Tests: keepAliveTabs.test.ts proves an included path's instance survives
a round trip (1 mount, 2 activations) while a detail path remounts (2
mounts); useCachedResource.test.ts proves no refetch inside the TTL,
exactly one refetch after it lapses, safe use outside KeepAlive, and
keep-last-value + sticky-ready semantics on a rejected refresh.
Full suite (706 tests), type-check, and build all green; built bundle
carries the new KeepAlive wiring (web/dist/neode-ui/assets).
