sp-javy-cli-linux-arm64	Platform wrapper for Javy v8.1.1 CLI on linux-arm64 — downloads, verifies SHA-256, exposes getJavyBinary() path. Consumed by wasm-compiler-javy via optionalDependencies.

sp-javy-cli-linux-arm64

Symbol	Kind	Responsibility
getJavyBinary	Function	Returns the absolute filesystem path to the bundled Javy binary under bin/javy
JAVY_PLATFORM	Constant	Platform triple: "linux-arm64"
JAVY_VERSION	Constant	Pinned upstream version: "v8.1.1"

File Structure: packages/devtools/tooling/javy-cli-linux-arm64/src/index.ts

Sibling packages:

• @suaveplan/javy-cli-darwin-arm64 — macOS ARM64 variant
• @suaveplan/javy-cli-darwin-x64 — macOS x64 variant
• @suaveplan/javy-cli-linux-x64 — Linux x64 variant
• @suaveplan/javy-cli-win32-x64 — Windows x64 variant
• @suaveplan/wasm-compiler-javy — consumer that spawns the binary

Patterns:

Quick Start:

import { getJavyBinary } from "@suaveplan/javy-cli-linux-arm64";
const binaryPath = getJavyBinary(); // absolute path to bin/javy

Constraints:

• os: ["linux"], cpu: ["arm64"] — npm/bun skip installation on mismatched platforms
• postinstall script downloads the binary from GitHub releases and verifies SHA-256 (c160127f4f41000216790e24bcfda860c51b0c5cc12808eb3691a0de88faa53a)
• Set JAVY_SKIP_DOWNLOAD=1 to skip download for offline CI; you MUST manually seed bin/javy
• Throws if binary is missing (postinstall failed or skipped without seed)
• Consumed exclusively through optionalDependencies by @suaveplan/wasm-compiler-javy

Checklist:

• getJavyBinary() returns an absolute path that exists after postinstall
• JAVY_VERSION matches the upstream release pinned in postinstall
• Setting JAVY_SKIP_DOWNLOAD=1 without seeding causes a clear runtime error
