# C0PY Upstream Capability Matrix

This matrix defines how C0PY consumes high-value upstream ideas without creating duplicate runtimes or conflicting sources of truth.

| Upstream | Classification | Adopt | Do not adopt |
|---|---|---|---|
| Mahanaicoach/ai-site-cloner | CHERRY_PICK / REIMPLEMENT | deterministic extraction, compact state deltas, responsive probes, canvas capture patterns, spec generation/linting, pixel + CSS root-cause QA, resumable manifests | duplicate orchestration/runtime ownership |
| jongko54/webEmbedding | CHERRY_PICK / REIMPLEMENT | HAR capture/replay contracts, authenticated storage-state capture, evidence artifacts, replay-readiness, failure taxonomy, verification patterns, MCP surface | a second canonical evidence model |
| tentenco/ai-website-clone | REIMPLEMENT / REFERENCE_ONLY | clone/adapt/blend modes, evidence-confidence model, reference ledger, motion audit, deterministic acceptance gates | duplicate capture pipeline |
| Omerfaruk-aydn/sitecloner | CHERRY_PICK / REIMPLEMENT | media discovery, yt-dlp/ffmpeg integration patterns, animation extraction, interaction maps, source/clone recording and frame comparison | duplicate browser crawler and visual diff core |
| microsoft/playwright | DEPENDENCY | canonical browser automation/runtime | custom replacement browser runtime |
| Chrome DevTools Protocol | DEPENDENCY | DOMSnapshot, CSS, Animation, Network, Runtime, Accessibility, Performance, Coverage | undocumented browser scraping where a typed CDP domain exists |
| apify/crawlee | DEPENDENCY | request queue, crawl graph, browser crawl orchestration | separate canonical route ontology |
| browser-use/browser-use | ADAPTER | semantic exploration, task/workflow discovery | low-level deterministic measurement |
| browser-use/browser-harness | ADAPTER | authenticated real-browser/CDP exploration | canonical IR ownership |
| rrweb-io/rrweb | DEPENDENCY / ADAPTER | DOM mutation timeline, interaction record/replay | replacing C0PY evidence contracts |
| BabylonJS/Spector.js | ADAPTER | optional WebGL frame forensics | mandatory core dependency |
| mapbox/pixelmatch | DEPENDENCY | deterministic pixel diff primitive | single release score |
| dequelabs/axe-core | DEPENDENCY | accessibility verification | copied implementation |
| Google Lighthouse | DEPENDENCY / TOOL | performance/runtime comparison | product behavior truth |
| gildas-lormeau/SingleFile | ADAPTER | archival/reference snapshot only | copied AGPL code in C0PY core |
| webrecorder/browsertrix-crawler | ADAPTER | optional WARC/WACZ archival service | copied AGPL code in C0PY core |
| Stagehand | ADAPTER | semantic observe/extract/act where deterministic selectors are insufficient | source-of-truth capture engine |

## Import rules

1. Every source-derived implementation must record repository, commit SHA, source files, license, integration method and tests.
2. MIT/ISC/Apache components may be integrated according to their license and notices.
3. Copyleft components must stay behind a separately deployable adapter unless a deliberate licensing decision says otherwise.
4. Prefer dependencies over vendoring when the upstream public API is stable and sufficient.
5. Prefer reimplementation from behavior/specification when importing code would create architectural duplication.
6. No upstream project may define C0PY's schema, ontology or release criteria.
