Marc-André Bombeck 6b3d3fd840 feat(auth): branch login through a second-factor challenge
When a password is accepted for an account with a confirmed TOTP factor, the
login route no longer mints a session or token. It creates a single-use,
~5-minute MfaChallenge (the opaque ticket is stored only as a hash) and
returns HTTP 200 with data:null, error:null and meta.mfaRequired + mfaTicket +
methods. The client completes the login at POST /api/auth/mfa/verify with the
ticket + a TOTP or recovery code, receiving the exact same token bundle the
password path issues, with the session stamped second-factor-verified.

- The ticket is claimed once, atomically, only after the factor verifies, so
  two concurrent submissions can mint at most one session; no session ever
  exists before factor two.
- Wrong codes increment the ticket attempt counter and burn it at the cap
  (throttle, not an account lock); the anonymous verify surface is also
  rate-limited per IP.
- meta.mfaRequired is returned only after a valid password and the
  invalid-credentials response is identical regardless of MFA state, so an
  attacker without the password cannot enumerate MFA.
- The session/token tail is extracted to login-response.ts and shared by both
  the password path and the verify path, keeping the transport contract
  identical. OpenAPI registers the verify endpoint, the MFA management
  endpoints, and the mfaRequired login variant.

docs/ — internal reference + operator playbooks

The user-facing documentation lives at https://docs.healthlog.dev — that's the canonical surface for self-hosting guides, integration walkthroughs, AI-provider setup, and the doctor-report workflow.

The files in this directory are the internal operator playbooks, audit notes, and machine-readable specs that ship alongside the source:

  • api/ — the OpenAPI 3.1 spec for the native-client subset (iOS DTO codegen target). See api/README.md for the preview commands.
  • ops/ — backup / restore + encryption-key-rotation playbooks. These are the runbooks an operator reaches for during an incident.
  • self-hosting/ — horizontal-scaling notes (HEALTHLOG_PROCESS_TYPE=web|worker|all) and the deploy-pipeline recipe. Routine install steps stay on docs.healthlog.dev.
  • migration/ — release-by-release migration notes. Read the entry for the version you're upgrading from.
  • audit/ — per-release audit summaries archived for forensic traceability.
  • apple-store-connect-checklist.md — the iOS submission gate.
  • doctor-report.md — PDF generator design notes.
  • codex-protocol-spec.md — Codex / ChatGPT OAuth protocol reverse-engineering notes.
  • ui-guidelines.md — UI / a11y house style.
