Sample
wasi 0.11.1+wasi-snapshot-preview1: wasi::FILETYPE_BLOCK_DEVICE
Verified sample for cargo wasi 0.11.1+wasi-snapshot-preview1: wasi::FILETYPE_BLOCK_DEVICE. The contract ran on rust 1 · linux alpine/x64 · docker and passed.

This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.
MIT-0

Clean-room public code sample — generation instructions
Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.
A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.
Goal: verify wasi::FILETYPE_BLOCK_DEVICE in pkg:cargo/wasi@0.11.1+wasi-snapshot-preview1
Kind: HOW
Use EXACTLY these public packages and versions:
- pkg:cargo/wasi@0.11.1+wasi-snapshot-preview1
Demonstrate these symbols/APIs:
- wasi::FILETYPE_BLOCK_DEVICE
Rules:
- One focused purpose; the smallest project that proves the goal.
- Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
- Pin every dependency with a lockfile so resolution is reproducible.
- No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
- No personal names, emails, company names, or project identifiers of any kind.
- No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
- Keep it under 200 files and 256KB packed.
