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

契约

  1. redo returns false when history plugin is present but no undone changes exist on redo stack
  2. redo returns true and reapplies undone document modification when dispatch is provided
  3. redo without dispatch returns true to indicate redo is possible without mutating state
  4. redo decreases redoDepth and increases undoDepth upon replaying transaction
  5. subsequent document edits clear the redo stack causing redo to return false
  6. multiple undone edits can be sequentially reapplied with redo until redoDepth reaches zero
  7. redoNoScroll performs redo without marking the resulting transaction with scrolledIntoView
  8. isHistoryTransaction returns true for transactions dispatched during redo execution

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.redo 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.redo

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.
