# Work OS V2

The interaction target for the real Work OS operator: one room for consequential work, with proof, Nathan's word, machine work, outcomes, and receipts kept on one causal line.

  Not wired; five arcs remain

Selected room

## One causal field, not an AI chat home

Binding contract

## What the next team must preserve

consequence proof your word machine work outcome receipt

### One room

Line, Watch, field, selected causal line, tape, one drawer, and the mobile machine strip. No pages, tabs, assistant pane, or permanent navigation rail.

### Truth over theater

Facts and maybes remain distinct. Progress uses named stages and real units. Every claimed action reaches a trace or receipt.

### Nathan keeps authority

Suggestions are free; acting requires his word. Mail stops at a reviewed, receipted draft. Sending is never automated.

### History is append-only

Words remain verbatim. Machine interpretation stays separate. Corrections, undo, close, and reopen append rather than erase.

Handoff library

## Open these in order

1. Clickable prototype The selected interaction target. Exercise it before reading implementation detail.
2. Prototype-to-product implementation handoff Production owners, component boundaries, five build arcs, tests, and invariants.
3. Complete design guide Room hierarchy, visual constitution, interaction grammar, mobile, motion, and copy.
4. Internal Work OS tool guide How to build useful internal tools without creating maintenance work or fake automation.
5. Mobbin research addendum What current AI products taught us, what we borrowed, and what geography we rejected.
6. Completion and verification audit Requirement-level evidence, repaired gaps, honest production boundary, and remaining gate.

Production sequence

## Build the real product in five arcs

01

### Word

Real append-only words, options, judgments, correction, and receipts.

02

### Work

Editable effort proposals, approval, factual runs, stop, replay, and rejection.

03

### Memory

Dig, sourced deltas, promises, learned arithmetic, and corrections.

04

### Custody

Draft review and placement, provider receipts, close, and reopen.

05

### Daily driver

Real data, responsive behavior, keyboard, observability, rollout, and rollback.

Current proof

## What the prototype actually proves

36 end-to-end checkpoints
153 control and safety checks
44/44 declared actions exercised
0 external requests or console errors

It proves the interaction design and local behavior. It does not prove authenticated persistence, live source freshness, provider effects, production orchestration, or deployment readiness.
