06 / RELATED CASE STUDIES

All work

Built and testedRVM CAD Job Portal and RVM CAD Scheduler

Both connectors are merged with full test suites. Production activation and the CEO acceptance test had not been verified when this was written (20 Oct 2026).

Doors, not keys: read-only AI access to production data

Two connectors that let an AI assistant answer operational questions from live systems — without a database credential, without write access, and without ever returning a half-right number.

11 read-only tools on the job portal connector

Built and testedRVM CAD Job Portal

Merged with 616 of 616 tests passing at 48c3cab1 (23 Jun 2026). RVM approved describing the behaviour on 15 Nov 2026; production rollout state was not independently verified.

Interviews that schedule, record and file themselves

One interview, end to end in the Job Portal: a Google Meet space and invites, a consent gate before recording, a recording state machine, and Drive filing with metadata. Built in one commit, with 616 of 616 tests passing at that commit.
