An empty floor. Start with the information your machine needs.

Received result

Your answer will arrive here.

Examples, experiments and workspace controls
Live values

Connect a tool's inputs to see what it produces. You can try a branch before connecting it to Result.

Try your own inputs

Use a copy of the example to try your own data. Keep the problem's assumptions in mind, and predict the effect of a change before checking the output. You can also add another branch to compare two ways of doing the calculation.

Start at an output arrow, then click or drag to an input. Drag empty space to pan. Delete removes a selection. Ctrl/Cmd+Z undoes a change.
Context for this challenge

Compare writable mount paths with the explicitly approved locations.

The offline parser job should have scratch space but no ambient credentials or network.

Try a fresh construction

This clears this draft, including its undo history. Earlier successful attempts stay recorded. Build again without opening hints to record an independent attempt.

Stuck? Inspect a worked construction

The tools below form one possible solution. You can assemble it, follow its signals, and undo that change to return to your own construction.

Assumptions and test precision

These are invented records and deterministic policy checks. The browser runs no agent, shell command, MCP server or network request. Passing these fixtures establishes only the stated policy behaviour. Numerical tests allow a difference of 0.001. Lists and structures must also have the right shape.

Your last tested pieces can start the full construction. An existing draft there keeps its own pieces.

A timeout field is present but disables the bound

This check uses the pieces from “Preserve every profile finding”.

BOTIE

The worker has no mounts, credentials or network. Its timeout is zero. Predict whether the profile is eligible for isolation testing under the stated positive-timeout policy.
Execution profile
{
  "mounts": [],
  "credentials": [],
  "network": "none",
  "privileged": false,
  "timeout": 0

Use a number, text, or an array matching the requested result. For a matrix, put each row in brackets. Saving your prediction runs your current construction on these inputs and checks the earlier examples too.

Build a construction in the workspace above first. This case will test those pieces.

How would you prove that the launched worker cannot read an excluded file?

Run disposable probes against the runtime, not just its configuration.
