Go app for capturing and archiving HSA-eligible receipts: OIDC/PKCE auth against Authelia, SQLite storage with dual-write (filesystem + DB blob), mobile-first upload, and DB export. Adds AI receipt classification: a config.json catalog of people and categories (seeded into the DB on startup), a prompt builder that derives name-order/initial variants from the data (with same-surname ambiguity handling), and an Anthropic tool-use client behind POST /classify. Tests run against a mock endpoint; a live integration test is env-gated to the cheapest model. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
