From 746aa654574495b8225cae811b890af2dd1de1f4 Mon Sep 17 00:00:00 2001 From: "github-actions[bot]" Date: Sat, 28 Feb 2026 00:25:09 -0700 Subject: [PATCH 1/7] fix(cli): remove branch-compare references to non-existent module The branch-compare command was registered in cli.js and its exports added to index.js, but the implementation file src/branch-compare.js was never created. This caused two issues: 1. `codegraph branch-compare` crashed with ERR_MODULE_NOT_FOUND 2. `import('@optave/codegraph')` crashed entirely because index.js has a top-level re-export from the missing file, making the programmatic API completely unusable Remove the dead references until an implementation exists.

More critically, `import('@optave/codegraph')` also crashes because `index.js` has a top-level re-export from the non-existent `branch-compare.js`. This makes the entire programmatic API unusable. +- **Root cause:** The `branch-compare` command was registered in `cli.js` (lines 826–843) and its exports added to `index.js` (line 9), but the implementation file `src/branch-compare.js` was never created. +- **Fix applied:** Removed the `branch-compare` command from `cli.js` and the re-export from `index.js`. Tests pass (832/832), lint clean. + +--- + +## 10. Suggestions for Improvement + +### 10.1 Guard against missing module imports in index.js +Add a CI check or test that validates all re-exports in `index.js` resolve to existing files. A simple `node --input-type=module -e "import('./src/index.js')"` in CI would have caught this. + +### 10.2 Native complexity performance investigation +Native complexity computation (270.9ms) is 2.2x slower than WASM (125.9ms). Since complexity is a large fraction of build time, improving the native Rust complexity implementation would yield a meaningful overall speedup. + +### 10.3 Add a `--full` flag documentation hint to structure +The structure command shows "N files omitted. Use --full to show all files" but `--full` is not listed in `--help`.

Overall Assessment + +v2.5.0 is a substantial feature release that adds a full code quality suite — complexity metrics (cognitive, cyclomatic, Halstead, MI), community detection, execution flow tracing, manifesto rule engine, and shortest-path queries. All new features work correctly and produce meaningful output. + +Engine parity is **100%** — native and WASM produce identical nodes, edges, and quality metrics. Native parsing remains ~9x faster, and overall native build time is 28% faster. + +The one critical bug — `branch-compare.js` missing from source — breaks the programmatic API entirely (`import('@optave/codegraph')` crashes). This is a ship-stopping defect for any consumer using the package programmatically. The CLI is mostly unaffected since `branch-compare` uses a lazy import. + +All other 27 commands work correctly in both cold-start and post-build scenarios. Edge case handling is solid. Incremental rebuild is fast and accurate. The edge-drop bug from previous versions appears to be fixed. + +**Rating: 7.5/10** — The programmatic API crash is a critical regression that prevents a higher score. Once the `branch-compare` fix ships, this would be an 8.5/10 release given the breadth and quality of the new features. + +--- + +## 13.

Recovered the full implementation (568 lines) and integration test (192 lines, 7 tests) from git object 22c8185. This restores the cli.js command and index.js exports that were removed in 746aa65, now that the implementation file exists.

Investigation revealed the implementation (568 lines + 192-line integration test) existed but was lost in a git stash from the `fix/complexity-sql-sanitize` worktree and never committed.

All new features work correctly and produce meaningful output. Engine parity is **100%** — native and WASM produce identical nodes, edges, and quality metrics. Native parsing remains ~9x faster, and overall native build time is 28% faster. -The one critical bug — `branch-compare.js` missing from source — breaks the programmatic API entirely (`import('@optave/codegraph')` crashes). This is a ship-stopping defect for any consumer using the package programmatically. The CLI is mostly unaffected since `branch-compare` uses a lazy import. +All 28 commands work correctly in both cold-start and post-build scenarios. Edge case handling is solid. Incremental rebuild is fast and accurate. The edge-drop bug from previous versions appears to be fixed.
