High-Level Architecture

Six layers, one direction of flow: from a human, through knowledge and AI, out to readers.

ichi is a pipeline of trust. Signal and work flow down; only proposals flow back up. Nothing crosses the human gate without approval.

The layers

LayerRole
HumanThe origin and the final gate. Sets intent; approves or rejects output.
KnowledgeA single vault of notes, logs, and drafts. The system’s memory (Chapter 04).
AI Operating SystemAgents that gather signals, connect ideas, monitor health, and draft.
Executive OfficeA virtual C-suite that reviews the same work from many angles (Chapter 03).
ProductsichiOS, IAS Brain, WkndPrjct (Chapter 05).
ReadersThe public. They see only the finished, human-approved result.

Why one direction

The arrows are one-way for action. An agent can draft an essay, flag an anomaly, or propose a decision — but it cannot publish, spend, or ship. Those actions return to the human gate first.

This is the single most important design choice in ichi, and it is not a technical one. It is a governance one: automation earns trust by being reversible and gated, not by being autonomous.
