Code Review

This pull request renames the graph-storage crate to document-graph and updates all references, imports, and documentation across the codebase to reflect this change. The review feedback identifies minor layout alignment issues in the ASCII art diagrams within the document-format.md RFC document caused by the difference in name lengths, and provides suggestions to correct the formatting.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Confidence score: 5/5

• In node-graph/rfcs/document-format.md, the ASCII diagram border width is off by one character around document-graph, which can make the RFC harder to read or copy accurately but does not affect runtime behavior; this PR is safe to merge, and you can de-risk fully by fixing the box width/alignment before or immediately after merge.

<file name="node-graph/rfcs/document-format.md">

<violation number="1" location="node-graph/rfcs/document-format.md:214">
P3: The ASCII art box border is now misaligned — `document-graph` is one character longer than the previous `graph-storage`, so this line extends past the top/bottom borders. Remove one trailing space before the closing `│` to restore alignment.</violation>

<violation number="2" location="node-graph/rfcs/document-format.md:248">
P3: The ASCII art box right border is misaligned — `document-graph` is one character longer than the previous `graph-storage`, so this row is wider than the `┌───────────────┐` / `└───────────────┘` borders above and below. Remove the leading space before `document-graph` (or widen the entire box by 1 character) to fix the alignment.</violation>
