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

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. MenuItem constructor instantiates menu items with run command, label, title, and state predicate specs
  2. MenuItem render throws RangeError when neither icon, label, nor custom render function is configured
  3. MenuItem render with custom render function returns dom element and updates active, disabled, and display states
  4. Standard editor icons provide SVG path or text display specifications with positive dimensions
  5. Built-in command items joinUpItem, liftItem, selectParentNodeItem, undoItem, and redoItem are pre-configured MenuItem instances
  6. wrapItem creates MenuItem configured with wrapIn command and selection predicate for target NodeType
  7. blockTypeItem creates MenuItem configured with setBlockType command and active state check for target NodeType
  8. Dropdown and DropdownSubmenu instantiate collapsible menu elements wrapping item lists
  9. menuBar returns a ProseMirror Plugin instance configuring editor menu bar view

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 pkg:npm/prosemirror-menu@1.3.2
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/prosemirror-menu@1.3.2

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.
