Avalanche Read

Tesseract's own documentation states it is "built by Contributors behind the successful Yield Yak platform", and the same page routes developer support to the Yield Yak contributors' own Telegram channel (t.me/yakdevs) — corroboration from a second direction inside one first-party document. ONE-DIRECTIONAL: Yield Yak's own docs do not mention Tesseract, and Yield Yak is a pseudonymous contributor collective with no named individual, so no founder edge is or ever should be proposed on the Yield Yak side.

Confidence is computed from the corroboration sources — anti-circular firewall: self-sourced claims never reach High alone.
