PR Review: chore: gitignore napi-generated artifacts in crates/codegraph-core

Tasks:

• Gather context and read changed files
• Analyze against review criteria
• Post final review

Root Cause Analysis

Problem Being Solved: Running npx napi build --platform --release in crates/codegraph-core/ generates three build artifacts (index.js, index.d.ts, *.node) that are not committed to the repo but were previously missing from .gitignore, leaving the working tree dirty after a native build.

Why This Approach: Adding root-level .gitignore entries is the correct mechanism — these are build products analogous to grammars/*.wasm (already gitignored), dist/, target/, etc. A crate-local .gitignore would also work but would be less discoverable; the root-level pattern is consistent with how this repo already handles similar artifacts.

Risk Assessment: Zero risk. This is a purely additive configuration change to a non-code file. It does not silence warnings, relax rules, or hide real issues — it prevents untracked build artifacts from polluting git status.

Backlog Compliance

• Zero-dep: ✓ — no new dependencies of any kind
• Foundation-aligned: ✓ — pure housekeeping, no principle affected
• Problem-fit: 2/5 — infrastructure hygiene, does not directly reduce AI token waste or hallucinated deps, but it's necessary maintenance for the native engine workflow
• Breaking: No — no behavior changes, no API/CLI/DB schema impact
• Tier: 1 (zero-dep ✓ + foundation-aligned ✓)

Code Review

The diff is exactly right:

+crates/codegraph-core/index.js
+crates/codegraph-core/index.d.ts
+crates/codegraph-core/*.node

• Patterns are path-scoped to crates/codegraph-core/ — no unintended broad matching.
• *.node uses a glob, correctly covering all platform-specific binaries (e.g. codegraph-core.linux-x64-gnu.node).
• Placement in .gitignore is consistent with similar entries (grammars/*.wasm is the direct analogue).
• No crate-local .gitignore needed; root-level is appropriate for a monorepo.

One minor observation: the crates/codegraph-core/package.json likely specifies these same files as napi's output. Worth verifying nothing in that package.json tries to commit them (e.g. via files field), but this does not block the PR.

Final Recommendation

• Rating: ⭐⭐⭐⭐ (4/5)
• Action: APPROVE
• Reasoning: Correct, minimal, zero-risk fix for a real developer-experience issue. The patterns are appropriately scoped, consistent with existing ignore rules, and address exactly the problem described. The only reason it's not 5 stars is that it's purely infrastructure hygiene with low problem-fit to the core AI navigation mission — but that's inherent to the task, not a flaw in execution.

Greptile Summary

Adds three .gitignore entries for the artifacts emitted by npx napi build in crates/codegraph-core/, preventing them from appearing as untracked files after a local native build.

• crates/codegraph-core/index.js and crates/codegraph-core/index.d.ts are the napi loader and TypeScript declarations generated at build time.
• crates/codegraph-core/*.node catches the platform-specific native binary (e.g., codegraph-core.linux-x64-gnu.node), consistent with the existing grammars/*.wasm treatment for WASM grammar artifacts.

Confidence Score: 5/5

Safe to merge — adds only three targeted gitignore entries that ignore generated napi build artifacts and have no impact on runtime behavior.

The change is confined to .gitignore and correctly scopes each pattern to the crates/codegraph-core/ directory. The *.node glob matches all platform-specific binary names that napi emits, mirroring the existing grammars/*.wasm pattern. No logic, build system, or source file is touched.

No files require special attention.
