CLAUDE.md@public/files/bun/src/jsc/bindings/v8 claudeA

This file is byte-identical to the first copy the registry indexed. Same content hash, same audit grade.

CLAUDE.md@public/files/bun/src/jsc/bindings/v8 is agent-read markdown (claude) from modem-dev/ossrules.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# V8 C++ API Implementation Guide

This directory contains Bun's implementation of the V8 C++ API on top of JavaScriptCore. This allows native Node.js modules that use V8 APIs to work with Bun.

## Architecture Overview

Bun implements V8 APIs by creating a compatibility layer that:

- Maps V8's `Local<T>` handles to JSC's `JSValue` system
- Uses handle scopes to manage memory lifetimes similar to V8
- Provides V8-compatible object layouts that inline V8 functions can read
- Manages tagged pointers for efficient value representation

For detailed background, see the blog series:

- [Part 1: Introduction and challenges](https://bun.com/blog/how-bun-supports-v8-apis-without-using-v8-part-1.md)
- [Part 2: Memory layout and object representation](https://bun.com/blog/how-bun-supports-v8-apis-without-using-v8-part-2.md)
- [Part 3: Garbage collection and primitives](https://bun.com/blog/how-bun-supports-v8-apis-without-using-v8-part-3.md)

How to install

Latest version
mdr add modem-dev/ossrules/public/files/bun/src/jsc/bindings/v8/CLAUDE.md@git:20260915.977fced
Exact content
mdr add modem-dev/ossrules/public/files/bun/src/jsc/bindings/v8/CLAUDE.md@sha256:2292b9544ff31adc

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
