Instrument · one set of controls, three published studies

The Oversight Simulator

Set how deep your agents delegate, how many reviewers stand behind them and what share of the work gets verified. The lab's measured curves move as you go. A further panel joins on 13 October.

01 · Delegation Cliff coefficients

What the levers do to the quality margin

Modelled change in the quality margin

0.00

Each bar is your change in that lever times its coefficient. The pale bar behind it is one full increment. A negative total spends margin and a positive total buys it. The other nine levers in the article stay at zero here. Pricing Agent Autonomy, numbers table · linear-probe coefficients, Sobol sample, band-only, n = 4,948 · unit: band-standardised increment

Each lever alone, the other two held where you set them

Every strip shares one vertical scale, so a steeper line is a stronger lever. Because the article fits straight slopes, each sweep draws a straight line and leaves out the interactions it mentions. Pricing Agent Autonomy, numbers table · coefficients −1.499, +1.456, +0.308

02 · A further panel, and the audit desk

A further panel joins on 13 October

The panel takes this space on publication day.

publishes 13 October

The audit desk

Published on 1 October. Its budget counts tokens per audit. It has its own axis and its own two controls, and nothing else on the page reads them.

A Trial Balance for Agent Omissions, figure 3 · threshold from section 4 · 24 audits per cell

Share of injected omissions named correctly, 24 audits per point, one auditor model. The dashed line is the 0.80 threshold the paper uses. Click or press Enter on a budget to pick it. A Trial Balance for Agent Omissions, figure 3 · synthetic seeds 1 and 2

03 · SIGIL irreversibility tiers

How much of the worker's error a blocking reviewer can reach

A blocker stops approvals. At each tier SIGIL counted how many of the worker's errors were wrongful approvals, the kind a blocker can stop, and how many were wrongful rejections.

Each bar splits the unsupervised worker's errors at one tier into the two kinds. Hover or focus a row for the counts behind its share. Tier 3 produced no worker errors. Click or press Enter on a row to pick its tier. SIGIL paper, figure 2 · convex campaign, pooled over three seeds · net values from the SIGIL executive piece, the one table

    Simulation from published coefficients, not a deployed system

    This page watches no agents. Each panel takes numbers the lab has already printed and moves them with your settings, and every number keeps its source in small type beside it.

    Panel 01 adds three slopes from one study. Panels 02 and 03 read other studies, and nothing on the page converts one study's units into another's.
