Aria — voice-first ID verification. Every KYC flow assumes you can read a screen and line up a document in a box. Blind and low-vision users are excluded.
 
Aria does the same verification work with the visual channel removed: a 10-stage voice-guided flow (consent → doc front/back → liveness challenge → selfie → verdict) where instructions are spoken, the document is read by the app, and the verdict is spoken back. Transcript on screen is for sighted observers only.

Built as Hono + TypeScript: deterministic check engine (verified iff all checks pass, inconclusive never approves), DVS stub gateway + risk tier, consent gate with full purge on deny, and 100% synthetic AU fixtures (VIC/NSW DL, AUS passport). Models narrate and perceive only — they never decide. --no-meta decides identically to --meta (parity tested).
