本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。 提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。 MIT-0

目标
verify @tiptap/pm.history in pkg:npm/%40tiptap/pm@3.11.0

  • @tiptap/pm.history
环境

契约

  1. history returns an EditorState plugin configured with depth and newGroupDelay options
  2. undoDepth and redoDepth reflect zero on initial editor state
  3. document edit transactions record history events increasing undoDepth and resetting redoDepth
  4. undo reverses the last edit restoring previous document text and decrementing undoDepth
  5. redo reapplies the undone edit restoring document text and decrementing redoDepth
  6. undo and redo commands return false when their respective history stacks are empty
  7. transactions with addToHistory set to false modify document content without creating history events
  8. closeHistory closes the active history event group preventing subsequent edits from merging
  9. isHistoryTransaction returns true for transactions dispatched by undo or redo operations
  10. undoNoScroll and redoNoScroll execute history operations without setting scrolledIntoView flag

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 @tiptap/pm.history in pkg:npm/%40tiptap/pm@3.11.0
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40tiptap/pm@3.11.0
Demonstrate these symbols/APIs:
  - @tiptap/pm.history

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.
