feat(embed): expose node-gyp bootstrap

[jdx]

Summary

• expose aube’s existing locked, in-process node-gyp bootstrap through the stable embedding facade
• return the resolved executable path so a host can service aube’s private lazy-shim command without duplicating cache or install policy
• route standalone aube’s hidden command through the same public API

This lets embedders such as mise keep only a small command adapter while aube continues to own the node-gyp version, cache layout, npmrc propagation, and cross-process locking. It requires neither an ambient npm executable nor a separately installed aube binary.

Verification

• cargo test -p aube node_gyp
• cargo clippy --all-targets -- -D warnings
• cargo fmt --check

Note

Medium Risk
Touches the public embed surface and native-addon bootstrap path (cache, locking, Windows binary resolution). Failure modes affect lifecycle installs, not auth or user data.

Overview
Exposes aube’s in-process node-gyp bootstrap on the embedding facade so hosts (e.g. mise) can service lazy shims without an aube or npm binary.

bootstrap_node_gyp materializes the cached install and returns the resolved executable path. Standalone aube’s hidden __node-gyp-bootstrap command now uses the same API. Binary lookup uses is_file() across platform names so Windows .exe/.cmd caches are found, with a clearer error if bootstrap succeeds but no executable is present.

📝 Walkthrough

Walkthrough

The node-gyp bootstrap API resolves and returns the existing platform-specific executable. The embedding module re-exports this API, and the NodeGypBootstrap command prints the returned path.

Changes

Node-gyp bootstrap API

Layer / File(s)	Summary
Path-returning bootstrap API crates/aube/src/commands/install/node_gyp_bootstrap.rs	The cache helper is crate-private. bootstrap_node_gyp resolves and returns the existing executable, including Windows .exe files. It reports ERR_AUBE_EMBED_INSTALL_FAILED when no executable exists. A Windows-only test covers exe-only caches.
Embedding and command integration crates/aube/src/embed.rs, crates/aube/src/lib.rs	The embedding API re-exports bootstrap_node_gyp. NodeGypBootstrap calls it and prints the returned path.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 4d74a

When installation reports success but no executable is produced, embedded hosts receive an inconsistent error instead of the expected install-failure classification, which can impair lazy bootstrap handling. Merge should wait for this error-path fix.

Poem

A rabbit checks the cached file,
Finds the path without delay.
Windows .exe joins the trail,
The embed API leads the way.
The command prints it bright today.

Greptile Summary

Exposes the existing locked node-gyp bootstrap through the embedding facade and routes the standalone hidden command through that API.

• Returns the resolved node-gyp executable path to embedding hosts.
• Resolves only regular files and supports the Windows .exe shim.
• Adds the required stable identifier to the post-bootstrap missing-executable error.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.

Important Files Changed

Filename	Overview

crates/aube/src/embed.rs	Re-exports the node-gyp bootstrap through the stable embedding facade.
crates/aube/src/lib.rs	Routes the hidden standalone bootstrap command through the public embedding API and prints the resolved path.

177-185: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Attach the install-failure code to the fresh-bootstrap failure path.

ensure_cached returns its own uncoded error at Lines [129]–[134] when installation reports success but leaves no candidate file. bootstrap_node_gyp therefore does not reach this code = ERR_AUBE_EMBED_INSTALL_FAILED expression for that failure case. Add the same code to the ensure_cached error, or move the final no-binary check into this public function. Add a test that asserts the returned error code.
