  withheld — the ergonomics check `authentication_documented` asks whether a
  developer-facing API documents how to authenticate. Apartments.com exposes
  no such API, so no `Authentication` pointer is wired. This artifact records
  the ONLY credential models that exist, both of which are partner seams.

- name: digital-feeds-ftp
  direction: inbound (vendor -> Apartments.com)
  mechanism: FTP username/password issued out-of-band
  evidence: >-
    https://propertyhelp.apartments.com/article/1041-how-do-i-connect-my-listing-to-apartmentscom-using-mri-market-connect
    (HTTP 200): "Prerequisites — You must identify the following FTP server
    information from the ILS you wish to add: FTP Server Name, FTP Login
    (Username), FTP Password."
  gate: >-
    Requires (a) a paying Apartments.com advertising contract, (b) application
    via Feeds@apartments.com or
    https://www.apartments.com/advertise/advfeeds, and (c) an approved
    third-party feed vendor. No API key is ever issued and no data returns to
    the caller.
- name: mls-syndication-optin
  direction: inbound (MLS -> Apartments.com)
  mechanism: >-
    No credential is issued to the publisher at all — a licensed agent toggles
    Apartments.com syndication inside their own MLS system.
  evidence: https://propertyhelp.apartments.com/collection/1201-mls-integrations (HTTP 200)
  gate: MLS membership (Bright MLS, ARMLS, REcolorado, OneKey MLS, SmartMLS,
    NorthstarMLS, MLS PIN, Garden State MLS, New Jersey MLS, Aspen Glenwood MLS
    documented) plus, in practice, a real-estate licence.
- name: web-session-login
  direction: human
  mechanism: ordinary web session login (no documented developer scheme)
  urls:
  - https://www.apartments.com/prosumer/login/
  - https://www.apartments.com/customers/login
  note: >-
    Both return HTTP 403 to non-browser clients; they are account portals for
    landlords and renters, not an identity provider a developer can integrate.
