コントラクト

  1. StepMap is exported by @tiptap/pm/transform as a class constructor
  2. StepMap maps untouched positions before and after the change range correctly
  3. StepMap maps insertion positions according to association parameter
  4. StepMap maps deleted ranges and marks positions as deleted in mapResult
  5. StepMap.invert creates an inverted mapping reversing old and new ranges
  6. StepMap.empty represents an identity mapping with no offset
  7. StepMap.offset shifts all positions by a given integer offset
  8. StepMap forEach iterates through replacement ranges with old and new offsets

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.StepMap 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.StepMap

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.
