+Overpass query validation, geometry simplification, disk caching and upstream
+transport now have separate modules; military-installation search reuses that
+transport. Regional briefing combines separate place, news and weather sources,
+while weather effects uses only the weather source. Existing process-scoped
+caches, rate limits, stale fallbacks and route ordering are preserved.
+
+Local voice has separate HUD-summary, debug-log and Realtime-token handlers,
+with tool definitions and instructions in dedicated files. The factory accepts
+an optional `annotationGuidance` paragraph; its default instructions and all 28
+tool definitions remain unchanged. `sourceRoot` resolves debug logs against the
+application directory. Standalone key setup accepts the same directory option
+for its environment store and preserves boot provenance, loopback/origin guards,
+atomic credential writes and development-only registration.
+
+Node-only package entries expose Overpass, military installations, regional
+services, local voice and standalone key setup. Importing them starts no network
+acquisition. Browser layer lifecycle, rendering and voice execution stay in their
+existing modules.
