Argon2id password hashing (PHC format, self-encoded/decoded without an external lib) with constant-time verification, UserStore (create/get by email and id) and SessionStore (opaque crypto/rand tokens, SHA-256 hashed in DB, create/lookup/revoke, last_seen_at bump on lookup). HTTP layer: Register/Login/Logout handlers + RequireAuth middleware. Login uses a dummy-hash path so unknown-email and wrong-password yield the same timing/shape, narrowing user enumeration. Tokens accepted via Bearer header (native clients) or session cookie (HttpOnly, SameSite=Lax). Routes wired in api.go: POST /auth/register, /auth/login, /auth/logout. Verified with go test, go vet and an end-to-end smoke test against a real PostgreSQL container (register/login/logout/duplicate/short-pw/wrong-pw). OIDC (Phase B part 2) follows next; the issueSession helper is reused.
