+# Domus
+
+A household management system.
+
+## Overview
+
+Domus is where I keep household records. Today that's an inventory of the stuff we own and a filing cabinet for family documents. More may come; the name is broader than the current scope on purpose.
+
+Inventory replaces [homebox](https://homebox.software/). Documents replace [paperless-ngx](https://docs.paperless-ngx.com/). Both do more than I need, and I want to keep only the parts I'll actually use.
+
+Scope is one household. No multi-tenancy, no public sharing, no login screen — authentication happens at the network layer via a reverse proxy header, same pattern as [ketchup](https://github.com/kejadlen/ketchup).
+
+## Domain model
+
+### Assets
+
+An **asset** is something I own worth tracking. Each asset has:
+
+- a markdown description, with the first line as the display name
+- tags, primarily for location ("garage," "kitchen drawer")
+- purchase information: where I bought it, when, how much, optional receipt
+- a maintenance log for things that need periodic attention
+
+Purchase dates are fuzzy. Some receipts are decades old, and forcing an exact day when I only remember the year is friction I don't want. A purchase date can be a year, a year and month, or a full date.
+
+### Documents
+
+A **document** is any file the household wants to keep findable — tax returns, school records, contracts, warranties, manuals, medical paperwork. Documents don't have to relate to the home itself; the inventory is one source of documents, not the only one. Documents have tags. OCR comes later.
+
+Where a document does relate to an asset (a receipt, a manual), the two cross-reference each other.
+
+## Stack
+
+Same shape as [ketchup](https://github.com/kejadlen/ketchup): Roda for routing, Sequel and SQLite for persistence, Phlex for views, Alpine.js on the client, Puma serving it.
+
+## Status
+
+Early. No code yet — this README is the design sketch.
