Vaultio

Attest is the talent side of Vaultio. Vaultio is where firms hire; Attest is what an engineer carries into that hiring, their own evidence profile, built from work they actually did. An engineer connects GitHub and runs a local script that reads real commit history into verified records: what was built, in what repo, sustained over what period, each one hashed so it can be checked and can't be edited after the fact. Meta Spark then writes a timed exercise from that evidence, asking the candidate to reason about a system they have worked in rather than answer a generic coding question. Their written reasoning is graded independently by Muse Spark 1.3 and Muse Wonder 1.0, both instructed to ground every score in exact quotes and repository evidence. Anything a grader cannot support is flagged for human review rather than scored. The full dossier exports as a PDF. The problem: an engineer's whole application is a claim, a CV and a list of skills, with no way to show what they built and be believed. Attest turns the claim into a record, so the proof travels with the candidate into Vaultio and any other hiring process. Stack: Next.js, Supabase, Cloudflare Worker calling Meta's Model API.
