inbox-relay-demo is a privacy-first demo of an inbox triage agent for job-search mail, built in TypeScript. It labels synthetic recruiter inbox mail into 8 categories : interview, offer-process, recruiter/new, recruiter/replied, rejects, application, read-later, promos using a local rules baseline plus a Meta model second opinion, with a safety screen and an agreement gate that only proposes archive when rules and model agree at confidence 0.85 or higher. Interview, offer, recruiter, unknown, and blocked mail never leave the machine; only generic template mail reaches the model, and the demo runs on synthetic data only, with no real mail and no Gmail credentials. It proves the privacy and gate design on a 67-email synthetic set before the real Relay agent ships it on real mail, dry-run and label-only first.
