+This directory is the reconstructed source skeleton for the compiled admin dist.
+
+Goals:
+- preserve route/page/module boundaries discovered from the compiled bundle
+- provide a safe place to rebuild maintainable source without disturbing `src/`
+- gradually replace placeholders with reconstructed implementations
+
+Current state:
+- runtime module skeletons are in `runtime/`
+- route and navigation registries are in `config/`
+- page placeholders mirror the compiled route tree in `pages/`
+- recovered page descriptors with real API/state/table/form logic now exist for:
+  - `pages/DashboardOverviewPage.js`
+  - `pages/finance/FinancePlanPage.js`
+- the following route groups already have placeholder source files:
+  - auth
+  - dashboard
+  - config
+  - server
+  - finance
+  - user
+  - error pages
+
+This tree is intentionally incomplete at the implementation level, but complete at the
+module-boundary level for the routes identified so far.
