컨트랙트

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