The File view gains a Source tab: the file itself, top to bottom, with the Symbol view's line grid, gutter ports and call-site links, a line-anchored callee rail, and — in the left margin — an arc for every call that stays inside the file, drawn from the calling line to the callee's definition line. The arcs are the point. Source order is already a layout, chosen by whoever wrote the file, so a file's internal call structure can be drawn with no algorithm placing anything. Crabviz's idea, in the one place it is legible. Everything is arithmetic, not measurement. The Symbol view queries the laid-out DOM to place a callee row beside its line; a 6 820-line file cannot afford that. Here a line is exactly 20px at `10 + (n - 1) x 20`, so ~90 line elements exist at a time and the arcs, ports, rail rows and connectors are all functions of a line number. `src/mcp/tools.ts` scrolls at a 16.6ms median frame. - `GET /api/filecode/<path>` — outline, one call group per (caller, callee) PAIR with its call-site lines, unresolved references, and the file's length. The source is NOT in it: it pages through `/api/source` 800 lines at a time with a discarded 150-line lead-in, so a page starting inside a block comment does not render prose as code, and so the ports and arcs are complete from the first frame while the text fills in behind them. - `intraFileCalls` is counted over the groups actually returned, so the header and the picture under it cannot disagree once a cap bites. - Above 40 arcs the diagram narrows to the symbol under the pointer (or the one the scroll position is inside) and the header states the total. Accent is for the pointer only, never for the filter. - Sticky outline rail at >= 1400px, following the reader down the file. - `QueryBuilder.getUnresolvedReferencesInFile` — one indexed lookup instead of one per symbol; `buildOutlineEntries` lifted out of `/api/file` so both readings of a file draw the same rows.

🚀 Project Structure
Inside of your Astro + Starlight project, you'll see the following folders and files:
.
├── public/
├── src/
│ ├── assets/
│ ├── content/
│ │ └── docs/
│ └── content.config.ts
├── astro.config.mjs
├── package.json
└── tsconfig.json
Starlight looks for .md or .mdx files in the src/content/docs/ directory. Each file is exposed as a route based on its file name.
Images can be added to src/assets/ and embedded in Markdown with a relative link.
Static assets, like favicons, can be placed in the public/ directory.
