Search: `/` or ⌘K focuses the box; results arrive grouped by kind with their
glyph, signature and file:line, ↑/↓/Enter walk them, Esc dismisses. A group
appears where its best result did, so flattening the groups reproduces the
ranking the keyboard walks — the panel's flat item list IS that concatenation.
A flow question ("how does X reach Y", "X -> Y") is recognised and searches
both endpoints with a note, rather than offering a row that would land on the
phase-2 Flow view.
Entry points answer "where do I start" on the empty screen and in the resting
palette, all derived from the graph: routes, files that run something at module
level (the engine records a top-level statement as an edge out of the file node,
which is what makes src/bin/codegraph.ts the root of the CLI flow — ranked by
calls x the files they reach, so a registration table calling into itself does
not outrank the CLI), and the most depended-on symbols. Tests are excluded from
both derived lists.
Trail: hops record the direction they were walked (→ into a call, ← up to a
caller), clicking one truncates back to it, Clear keeps the place instead of
throwing it away, and the whole walk travels in the URL. A shared or reloaded
trail arrives as ids, so hops learn their names back through a new batch
endpoint and a session name cache — without it, walking back across a
truncation redrew earlier hops as raw hashes. "Read as flow" stays hidden until
there is a Flow view to send it to.
New endpoints: /api/entrypoints and /api/nodes. New engine reads:
getTopCallingFiles, getFileDependentCounts.

A row's position comes from measuring the laid-out DOM, so between Svelte
creating it and the first relayout it has no place to be. Drawing it at
top: 0 stacks the whole rail at its head for a frame; keeping the previous
symbol's coordinates is worse. It stays invisible until it has been placed.

The core screen of `codegraph ui`: who calls a symbol on the left, its
verbatim body in the middle with a port on every line that has an outgoing
edge, and what it calls on the right — each callee row placed beside the line
that makes the call, with a hairline connector between them.
The callee rail is the part that is not a list. A row wants to sit at the
centre of its first call-site line and is pushed down only when that would
collide with the row above, so the rail keeps source order; the connector
still runs to the real line, so the displacement is visible rather than
silent. Positions come from measuring the laid-out DOM, so they are
recomputed on resize, on font load and whenever a fold opens.
Honesty is carried in the drawing, not in a footnote: a filled port means the
resolver matched something on that line and a hollow one means it only
guessed; uncertain connectors are dashed and their targets fold away behind
their count; synthesized edges are dashed differently and tagged with the
mechanism that made them; references that leave the index are text with a
soft underline rather than links to nowhere, and they are counted. Long
bodies keep their head plus a window round every call site — windowed on
graph edges only, since a function calling `console.log` two hundred times
would otherwise window round every line and buy nothing. Containers over 80
lines show a members outline with per-member fan-in/fan-out instead of 700
lines of braces.
Two small additions to the read-only API this needed:
* `/api/node` gives every outline member its own fanIn/fanOut (two batched
queries for the whole outline). A class's own fan-out is nearly always
zero because its methods do the calling, so without these the outline
cannot say which member carries weight.
* `/api/stats` gains `blastScale` — the denominator the blast bar is drawn
against, so one symbol's radius reads as wide or narrow *for this repo*.
It is measured across the index's 24 most-depended-on symbols (found with
a new `getTopDependedOn`, distinct dependents rather than edges), memoised
against the index stamp, and reported as sampled; a symbol wider than the
sample becomes the scale instead of overflowing the track.
Verified against a real index in a real browser: parity with the prototype on
`CodeGraph.sync` (259 lines, 27 callee rows, no overlaps), `GraphTraverser`
(20-member outline), a 773-line function (26 windows, 78 connectors), light
and dark, hover linking in both directions, keyboard-only navigation, and
reflow on resize and on fold toggles.

Adds `ui/` as an npm workspace (Svelte 5.56 + Vite 7, devDependencies only —
the engine's runtime dependencies are untouched) and chains its build into
`npm run build`, so the browser viewer ships inside `dist/` with everything
else: `build-bundle.sh` already copies `dist` wholesale and `pack-npm.sh`
packs that bundle.
Output is `dist/viewer/`, NOT `dist/ui/`: `src/ui/` is the engine's terminal
ui (shimmer progress + its worker) and tsc compiles it to `dist/ui/`, so
emitting there both deletes those modules — the CLI then dies at startup with
`Cannot find module '../ui/shimmer-progress'` — and would leave the static
server handing out compiled engine internals. The design spec is corrected to
match.
`scripts/check-ui-build.mjs` is the release guard: index.html must exist, be
non-trivial, and every local asset it references must be on disk, and the
compiled engine next door must still be intact. It runs after every UI build,
again in `build-bundle.sh` once the bundle stage has copied `dist`, and again
in `pack-npm.sh` once each archive is unpacked — so a broken viewer fails the
release instead of shipping a CLI that serves a 404.
`vite build` does not override an ambient NODE_ENV, so a shell or runner with
NODE_ENV=development silently shipped dev-mode Svelte (~13 kB of dev-only
runtime checks, warning in the user's console). The config now pins production
for `command === 'build'`; macOS and Windows ARM64 then emit byte-identical
bundle hashes.
The shell itself follows docs/design/codegraph-ui-design-spec.md §2–§3.1:
design tokens as CSS custom properties (light on bare `:root`, dark under both
`prefers-color-scheme` and `[data-theme="dark"]`), square corners, hairline
rules, one oxblood accent; top bar 48px / trail bar 34px / main; a hash router
over `#/s/<id>`, `#/file/<path>`, with `#/map` and `#/flow` reserved for phase
2. Fonts are vendored through @fontsource rather than fetched, so a local
reader works offline and never announces the project to a CDN.
Verified: clean `npm run build` from an empty dist on macOS and on the Windows
ARM64 VM (forward-slash asset URLs, CLI still starts, both assertion failure
modes exit 1); `dist/viewer` present in a real darwin-arm64 bundle and in the
packed npm platform package; shell geometry, tokens, all seven routes, both
themes and font loading checked in headless Chromium with no console errors;
`npm test` unaffected.
