Basic auth works and stays for the API, but a browser has no way to log out of it and the credential lives in the browser's keeping. A gated page now redirects to /login instead of raising a Basic prompt, the header names who is signed in and offers sign-out, and Basic remains for scripts.

Session tokens are stored as SHA-256 digests, so the table cannot be read back into working cookies. Cookies are HttpOnly, Path=/, SameSite=Lax — Lax being what stops another origin POSTing quarry's write forms on a reader's behalf — and Secure under TLS.

A password change or an account deletion ends that account's sessions; otherwise 'change your password' would leave the browser already holding one still signed in. Authorization for a cookie runs the same RoleOf lookup the password path uses, so a cookie is never worth more than a password.

safeNext keeps the post-login redirect on this site: a reader is at their most trusting on the hop straight after authenticating, which is exactly when an open redirect pays. check-in: 7bdf7a189b user: dmestas tags: trunk
