# Dogfooding Report: @optave/codegraph@3.1.4

**Date:** 2026-03-16
**Platform:** Windows 11 Pro (10.0.26200), x86_64, Node v22.18.0
**Native binary:** @optave/codegraph-win32-x64-msvc@3.1.4
**Active engine:** native (v3.1.4)
**Target repo:** codegraph itself (398 files)

---

## 1. Setup & Installation

| Step | Result |
|------|--------|
| `npm install @optave/codegraph@3.1.4` | OK — 144 packages, 0 vulnerabilities |
| `npx codegraph --version` | `3.1.4` |
| Native binary package | `@optave/codegraph-win32-x64-msvc` v3.1.4 (npm package.json) |
| `npx codegraph info` | `Native version: 3.1.4 (binary reports 3.1.3 — stale)` |
| Active engine | `native (v3.1.4)` |

**Note:** The `info` output shows "binary reports 3.1.3 — stale" because the Rust-compiled version string is baked at compile time and hasn't been bumped. The npm package version IS 3.1.4 and the engine loads correctly. This is cosmetic.

**Issue found:** `optionalDependencies` in the published `package.json` pins native binaries to `3.1.3`, not `3.1.4`. npm resolves the correct version because 3.1.4 exists on the registry, but the pin is wrong. Filed as #454.

---

## 2. Cold Start (Pre-Build)

All commands tested without a graph database present:

| Command | Result | Notes |
|---------|--------|-------|
| `query` | PASS | `codegraph [DB_ERROR]: No codegraph database found...` |
| `stats` | PASS | Same graceful DB_ERROR |
| `deps` | PASS | Same |
| `where` | PASS | Same |
| `map` | PASS | Same |
| `cycles` | PASS | Same |
| `impact` | PASS | Same |
| `context` | PASS | Same |
| `fn-impact` | PASS | Same |
| `diff-impact` | PASS | Same |
| `structure` | PASS | Same |
| `export` | PASS | Same |
| `search` | PASS | Same |
| `embed` | PASS | Same |
| `triage` | PASS | Same |
| `audit` | PASS | Same |
| `roles` | PASS | Same |
| `communities` | PASS | Same |
| `complexity` | PASS | Same |
| `models` | PASS | Lists 7 embedding models |
| `registry list` | PASS | Shows registered repos |
| `info` | PASS | Shows diagnostics |

All commands fail gracefully with a helpful message pointing to `codegraph build`.

**Commands not found in v3.1.4 CLI:**
- `fn` — use `query` instead
- `explain` — use `audit` or `context` instead
- `hotspots` — use `triage --level file` instead

These are listed in the dogfood skill template but were removed or renamed in the vertical slice refactoring (v3.1.4).

---

## 4. Rebuild & Staleness

| Test | Result |
|------|--------|

| Content change → incremental rebuild | PASS — only changed file + reverse deps re-parsed |
| Full rebuild (`--no-incremental`) | PASS — 5323 nodes, 11466 edges |
| Node counts stable after no-op | PASS — identical |

### Embed → Rebuild → Search Pipeline

| Step | Result |
|------|--------|
| Embed with minilm (1508 symbols) | PASS |
| Search after embed | PASS — relevant results |
| Full rebuild after embed | Not re-tested (would clear embeddings) |

---

## 5. Engine Comparison

### Build Results

| Metric | Native | WASM | Delta |
|--------|--------|------|-------|
| Nodes | 5323 | 5318 | +5 (0.1%) |
| Edges | 11466 | 11496 | -30 (0.3%) |
| Functions | 1129 | 1129 | 0 |
| Methods | 363 | 360 | +3 |
| Parameters | 2630 | 2664 | -34 |
| Constants | 354 | 318 | +36 |
| Call edges | 2348 | 2348 | 0 |
| Contains edges | 5316 | 5311 | +5 |
| Dynamic imports | 127 | 128 | -1 |
| Complexity fns | 1492 | 1488 | +4 |
| Function cycles | 11 | 11 | 0 |

Parity is excellent. Minor differences in parameter/constant/method counts are expected due to extraction heuristic differences between Rust and JS parsers. Call edges are identical.

### Performance Benchmarks

**Build Benchmark:**

| Metric | Native | WASM |
|--------|--------|------|
| Full build | 1,350ms | — |
| Per-file build | 3.4ms | — |
| No-op rebuild | 15ms | — |
| 1-file rebuild | 550ms | — |
| Query (fnDeps) | 0.8ms | — |
| Query (fnImpact) | 0.8ms | — |
| Query (path) | 0.8ms | — |
| Query (roles) | 6.4ms | — |

**Native build phase breakdown:**

| Phase | Time |
|-------|------|
| Setup | 56.9ms |
| Parse | 154.2ms |
| Insert | 235.0ms |
| Resolve | 5.6ms |
| Edges | 77.2ms |
| Structure | 8.6ms |
| Roles | 18.4ms |
| AST | 480.9ms |
| Complexity | 33.7ms |
| CFG | 70.8ms |
| Dataflow | 94.5ms |
| Finalize | 106.2ms |

**Complexity sanity check:** Native `complexityMs` (33.7ms) is much lower than WASM equivalent, confirming the native binary is not stale for complexity computation.

**Query Benchmark:**

| Metric | Native | WASM |
|--------|--------|------|
| fnDeps depth 1 | 0.8ms | 0.8ms |
| fnDeps depth 3 | 0.8ms | 0.8ms |
| fnDeps depth 5 | 0.8ms | 0.7ms |
| fnImpact depth 1 | 0.8ms | 0.7ms |
| fnImpact depth 3 | 0.7ms | 0.7ms |
| fnImpact depth 5 | 0.7ms | 0.7ms |
| diff-impact | 16.7ms | 16.0ms |

Query performance is equivalent across engines (expected — queries run on SQLite, not the parser).

**Incremental Benchmark:**

| Metric | Native | WASM |
|--------|--------|------|
| Full build | 1,471ms | — |
| No-op rebuild | 13ms | — |
| 1-file rebuild | 542ms | — |
| Import resolution (native batch) | 2.7ms (175 imports) | — |
| Import resolution (JS fallback) | 7.1ms (175 imports) | — |

| JSON-RPC initialize | PASS — protocol version 2024-11-05 |

### Programmatic API

| Test | Result |
|------|--------|
| ESM `import * from '@optave/codegraph'` | PASS — 56 exports including all data functions, errors, constants |
| CJS `require('@optave/codegraph')` | **FAIL** — `ERR_PACKAGE_PATH_NOT_EXPORTED` (#455) |

Key exports verified: `buildGraph`, `loadConfig`, `contextData`, `explainData`, `whereData`, `fnDepsData`, `diffImpactData`, `statsData`, `EXTENSIONS`, `IGNORE_DIRS`, `EVERY_SYMBOL_KIND`, `AnalysisError`, `DbError`, `ConfigError`.

### Registry Flow

|------|--------|
| `registry add <dir> -n <name>` | PASS |
| `registry list` / `registry list --json` | PASS |
| `registry remove <name>` | PASS |
| `registry prune --ttl 0` | PASS — pruned 36 stale entries |

### Config

| Test | Result |
|------|--------|
| `.codegraphrc.json` loaded | PASS — verbose output confirms config loaded |
| Build respects config | PASS |

## 8. Bugs Found

### BUG 1: Native binary optionalDependencies pinned to 3.1.3 (Medium)

- **Issue:** [#454](https://github.com/optave/codegraph/issues/454)
- **PR:** Fixed on this branch (package.json updated)
- **Symptoms:** `codegraph info` shows "binary reports 3.1.3 — stale". Published package.json has wrong pins.
- **Root cause:** Release workflow or `sync-native-versions.js` didn't update pins before publishing v3.1.4.
- **Fix applied:** Updated all `@optave/codegraph-*` pins from `3.1.3` to `3.1.4` in `optionalDependencies`.

### BUG 2: CJS require() fails with ERR_PACKAGE_PATH_NOT_EXPORTED (Medium)

- **Issue:** [#455](https://github.com/optave/codegraph/issues/455)
- **PR:** Open — needs decision on CJS support strategy
- **Symptoms:** `const cg = require('@optave/codegraph')` throws `ERR_PACKAGE_PATH_NOT_EXPORTED`.
- **Root cause:** Package `exports` field only defines `import` condition, no `require` or `default`. Package is `"type": "module"`.
- **Fix applied:** None yet — needs architectural decision (CJS wrapper, `default` export, or ESM-only documentation).

## 9. Suggestions for Improvement

### 9.1 Update dogfood skill command references
The dogfood skill template references `fn`, `explain`, and `hotspots` as standalone CLI commands. These no longer exist in v3.1.4 — they were absorbed into `query`, `audit`/`context`, and `triage --level file` during the vertical slice refactoring. Update the skill to match current CLI.

### 9.2 `exports` command for barrel files
`exports src/db.js` returns "No exported symbols found" for barrel/re-export files. While technically correct (no function nodes in the file), it's confusing since `db.js` is a heavily-imported file (86 fan-in). Consider showing re-exported symbols with a note that they originate from sub-modules.

### 9.3 MCP tool count in skill template
The skill says to expect 23 tools (single-repo) / 24 (multi-repo). The actual count is now 31/32 after all the new commands were added. Update the expected counts.

### 9.4 `info` "stale" warning is confusing
The "binary reports 3.1.3 — stale" warning appears even when the native engine works correctly at the right version. Consider suppressing the stale warning when the npm package version matches the expected version, or rewording it to clarify it's cosmetic.

- [ ] Test `co-change --analyze` followed by `co-change` queries

---

## 11. Overall Assessment

v3.1.4 is a solid release delivering a massive architectural refactoring (Phase 3 vertical slice) without functional regressions. All 398 files parse correctly, all CLI commands work, engine parity is excellent (0.1% node difference), and the test suite passes (1862 tests, 0 failures). The new qualified names, graph model, and decomposed modules all function correctly.

Two bugs found:
1. **Native binary pins stale** (#454) — cosmetic/correctness issue, trivial fix
2. **CJS require() broken** (#455) — affects CJS consumers, needs design decision

The vertical slice refactoring is impressively clean — despite moving thousands of lines across modules, the CLI surface and MCP tools all work identically to before. Build performance is good (1.35s full build, 13ms no-op, 550ms 1-file rebuild). Query latency is sub-millisecond.

**Rating: 8/10** — Functionally excellent. Deducted for the stale native binary pins (should be caught by release automation) and the CJS export gap. The architectural improvements are substantial and well-executed.
