+- **PR:** Fixed via reverse-dependency cascade in `builder.js:444`
 - **Symptoms:** Touching one file (appending a comment) and running incremental build drops 46 edges (33 calls, 12 imports, 1 reexport). Full rebuild restores them.
-- **Root cause:** The incremental edge deletion query (`DELETE FROM edges WHERE source_id IN (changed file) OR target_id IN (changed file)`) removes ALL edges touching the changed file — including incoming edges from other files. The edge rebuilding phase only processes changed files, so edges from other files that reference the changed file's exports are lost.

+- **Root cause:** The incremental edge deletion query removed ALL edges touching the changed file — including incoming edges from other files. The edge rebuilding phase only processed changed files.
+- **Fix applied:** Reverse-dependency cascade — when a file changes, files that import it are identified and their outgoing edges are re-resolved. Edge deletion now only removes outgoing edges for reverse-dep files (nodes/IDs preserved).

 ## 9. Suggestions for Improvement
 
-### 9.1 Add `--db` flag to `embed` command
-Currently `embed` doesn't support `--db`, unlike all other commands. This makes it harder to test against specific databases.
+### 9.1 ~~Add `--db` flag to `embed` command~~ — DONE
+~~Currently `embed` doesn't support `--db`, unlike all other commands.~~ Fixed: `embed` now supports `-d, --db <path>`.
 
-### 9.2 Redirect HuggingFace library console output
-The `@huggingface/transformers` library prints "dtype not specified..." via `console.warn` which goes to stderr, but the library may have other `console.log` calls that could leak to stdout. Consider monkey-patching `console.log` during model loading or using the library's logging configuration.
+### 9.2 ~~Redirect HuggingFace library console output~~ — DONE
+~~The `@huggingface/transformers` library prints "dtype not specified..." via `console.warn` which goes to stderr.~~ Fixed in PR #117: `loadModel()` messages switched from `console.log` to `info()` (stderr-routed logger). The HF library's own `console.warn` goes to stderr naturally and doesn't affect stdout pipe consumers.
 
-### 9.3 Incremental rebuild needs reverse-dep edge cascade
-The most impactful fix would be making incremental rebuilds re-resolve edges for files that import changed files (reverse dependency cascade). This would fix Bug #4 and ensure incremental builds produce identical results to full builds.
+### 9.3 ~~Incremental rebuild needs reverse-dep edge cascade~~ — DONE

 Codegraph v2.4.0 is a solid release with compelling new features — co-change analysis and node role classification add meaningful value. The tree-sitter Query API migration delivers measurable performance gains. Engine parity remains perfect.
 
-**However**, two high-severity bugs were found:
+**All 4 bugs found during dogfooding have been fixed:**
 
-1. Windows users get no native engine due to a missing `optionalDependencies` entry — easy fix, already submitted.
-2. Incremental rebuilds silently drop edges — this is the most concerning issue as it produces incorrect graph data without any warning. Users relying on incremental builds may have missing edges.
+1. ~~Windows users get no native engine~~ — Fixed in PR #117 (added win32 to optionalDependencies)
+2. ~~extractLeadingComment crashes~~ — Fixed in PR #117 (bounds check)
+3. ~~search --json leaks to stdout~~ — Fixed in PR #117 (switched to stderr logger)
+4. ~~Incremental rebuild drops edges~~ — Fixed via reverse-dep cascade in builder.js
 
-The 3 simpler bugs are fixed in PR #117. Bug #4 (incremental edge drop) needs deeper work.
+3 of 4 improvement suggestions also addressed (9.1 `--db` on embed, 9.2 HF output, 9.3 reverse-dep cascade). Only 9.4 (update notification testing) remains open as low priority.

-Justification: All commands work correctly, engine parity is perfect, and the new features (co-change, roles) work well. The deduction is for: the missing win32 binary (-1, high impact for Windows), the incremental edge drop (-1.5, silently produces wrong results), and the stdout pollution in search --json (-0.5, minor but affects tooling integration).
+Original deductions were: missing win32 binary (-1), incremental edge drop (-1.5), stdout pollution (-0.5). All three are now fixed. Remaining -1: update notification untested, and the HF library's `console.warn` to stderr is cosmetic but not fully silenced.
