1. Enforce the 12h session lifetime server-side in requireAuth (reject a
session older than the TTL even if the sealed cookie is intact), so a
leaked cookie value can't be replayed indefinitely. Shared sessionTTL
const drives both the cookie MaxAge and the check.
2. Send X-Content-Type-Options: nosniff when serving user-uploaded
receipt/attachment bytes, so the browser won't sniff past the declared
(upload-time allowlisted) MIME type.
Update SPEC §2 and §6 accordingly; tests cover stale-session rejection.

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.
