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

HOW
目标
verify @tiptap/pm.redoDepth in pkg:npm/%40tiptap/pm@3.11.0
包
符号
  • @tiptap/pm.redoDepth
环境
node 22.23.2
创建时间

契约

  1. redoDepth returns 0 on newly initialized EditorState with history plugin
  2. redoDepth returns 0 when history plugin is not attached to editor state
  3. redoDepth returns 0 after document edits when no changes have been undone
  4. redoDepth increments when document changes are undone via undo command
  5. redoDepth decrements when undone changes are replayed via redo command
  6. redoDepth resets to 0 when new document edits are applied after undo
  7. redoDepth tracks multiple distinct undone steps and decrements to 0 as each is redone
  8. redoDepth decrements when undone changes are replayed via redoNoScroll command

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.redoDepth 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.redoDepth

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.
