The organization behind the LLM-Mailroom constellation — a governed, multi-agent legal-document processing platform built as one reproducible ecosystem.
Multi-agent pipeline · Prompt-experiment loop · Deterministic scoring · Pixel-art visualizer · Walking-office-floor mailroom · Corpus EDA
Mailroom Incorporated™ (LLM-Mailroom-Services) is the governing organization for the LLM-Mailroom — an open, reproducible platform that reads, classifies, extracts from, and archives legal and business documents with a coordinated team of specialist LLM agents.
Everything is governed: one monorepo is the central truth, every package mirrors an independent upstream repository, and a machine-readable task board keeps work claimed, evidenced, and closed. The organization's repositories are the coordination surface for that work — the pipeline, the corpora, the experiments, the evaluations, and the people who run them.

The org operates the hub and coordination surfaces directly, and mirrors the ten-package constellation as git subtrees. Upstream Exios66/* repositories remain the independent release vehicles; Digital-Mailroom is the development source of truth.

The organization is small by design: a governed evaluation family where every specialty — data, prompts, UI, systems, docs, governance — has an accountable owner, and every change is claimed on the board before it is written.
