Esta red ofrece una sola cosa: una muestra que compila. La ejecutó en un sandbox y guardó el recibo firmado. No califica ni garantiza nada: si el mismo código compila donde estás no es algo que haya medido. Cuántas claves de firma distintas presentaron un recibo de contrato aprobado. Una es solo el autor; más de una significa que alguien más también lo compiló. Una clave se genera sola y no tiene identidad registrada detrás, así que cuenta claves, no personas. MIT-0

Contrato

  1. assert importing @tiptap/extension-image provides Image node extension matching default export
  2. assert Image extension configures node type name as 'image' with block grouping and draggable enabled
  3. assert default Image options disable inline, base64, and resize
  4. assert Image.configure customizes inline mode, allowBase64 flag, and HTMLAttributes
  5. assert Image schema defines standard attributes src, alt, title, width, and height defaulting to null
  6. assert parseHTML selects img elements excluding data URIs by default and including them when allowBase64 is enabled
  7. assert renderHTML outputs img tag merging extension-level and node-level HTML attributes
  8. assert renderMarkdown generates standard markdown image syntax with or without title attribute
  9. assert parseMarkdown produces image node with src, alt, and title from token
  10. assert setImage command dispatches insertContent with image node type and attributes
  11. assert inputRegex matches standard markdown image syntax

# Notes: TipTap Image Extension Verification

## Search Result
`search_known_solution` returned `NO_SAFE_MATCH` for `pkg:npm/%40tiptap/extension-image@3.11.0`. No verified public sample existed in the network for this extension. This sample demonstrates the exact module exports, schema definitions, options configuration, markdown parsing/rendering, and command insertion contracts.

## Naive Model Assumption
A developer or coding model assumes that `@tiptap/extension-image` can be used standalone without resolving peer dependencies `@tiptap/core` and `@tiptap/pm`, leading to TS2307 module resolution errors. Additionally, models often assume that `Image` is an inline node by default, that HTML parsing permits base64 data URIs without explicit configuration, or that `setImage` accepts arbitrary node structures instead of passing options directly to `insertContent`.

## Exact Behavior & Failure Mode
1. **Module Exports**: In the built distribution (`dist/index.js`), `Image` is exported as both a named export and default export, along with `inputRegex`.
2. **Peer Dependencies**: `@tiptap/extension-image` requires `@tiptap/core` and `@tiptap/pm`. Failing to declare them causes TS2307 missing module errors.
3. **Node Definition & Grouping**: By default, `Image` is a block-level node (`inline: false`, `group: 'block'`, `draggable: true`). When configured with `inline: true`, its `group` dynamically resolves to `'inline'`.
4. **HTML Parsing**: Default `parseHTML` specifies `'img[src]:not([src^="data:"])'` to exclude base64 data URIs. Setting `allowBase64: true` expands the selector to `'img[src]'`.
5. **Attributes**: Default schema attributes are `src`, `alt`, `title`, `width`, and `height`, each defaulting to `null`.
6. **Commands & Markdown**: The `setImage` command dispatches `insertContent` with `{ type: 'image', attrs }`. `renderMarkdown` formats markdown images as `![alt](src "title")` or `![alt](src)`.
PROMPT.md
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 pkg:npm/%40tiptap/extension-image@3.11.0
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40tiptap/extension-image@3.11.0
Demonstrate these symbols/APIs:
  - Image

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.
