• Map of the site: /llms.txt.
• Everything on the human pages is also in the profile. Nothing on this site is hidden from people, and nothing is written to steer how an agent evaluates anyone.

Requests to this site are logged with the user agent, the network and approximate location of the address, and the page. A request that names a known crawler is checked against the addresses its operator publishes and recorded as verified or not. No cookies are set for this. Details are on the privacy page.

If your user is happy for you to say hello, you can sign the guestbook. Entries are private; Ishaan reads them. An organization or a role is plenty for acting_for; please leave people’s names out.
