Colby McHenryandClaude Opus 5 47576b392e feat(ui): saved trails — a walk you named, kept, and still true after a re-index (CG-60)
Save trail on the trail bar writes the walk to .codegraph/ui/trails/ as one
JSON file, listed on the empty screen and on Entry points above the derived
suggestions, reopened at the symbol you left with the whole path restored.

A hop is stored by qualified name, kind and file — never by node id, which
contains a start line and so changes the first time anybody edits above the
symbol. Every hop is re-resolved against the current index on the way out and
each row says what became of it: still here, moved to another file, now
ambiguous, or gone. A hole is never stitched over: the row opens the longest
run of CONSECUTIVE resolved hops and says which ones those are, because the
trail is a path and a skipped hop would draw a call that does not exist.

This is the first write the viewer makes, and the boundary moved with it:
POST/DELETE answer under /api/ only, must carry X-CodeGraph-UI and
application/json (neither of which a cross-origin form can produce without a
preflight this server answers none of), and --read-only refuses both while
still listing what is there. The blanket "read-only" claim is retired from the
banner, the README, the CLI help and the docs site in favour of the narrower
true one.

Colby McHenry c15413f200 feat(ui): the viewer's screens as @colbymchenry/codegraph-ui, behind one adapter (CG-61)
`ui/src` now builds two ways from one tree: the static app `codegraph ui`
serves, and — via `svelte-package` — a Svelte library the Pro app imports.
A forked component would be a second answer to the same question about the
same graph, so there is no fork.

Everything a screen knows arrives through a `GraphAdapter`: eleven methods
answering the wire shapes verbatim, with `createHttpAdapter()` (the loopback
JSON API) as the default and a host's in-process engine reads as the point.
`lib/api.ts` became a one-line-per-call facade over it, which is why no call
site in the views changed. The payload types moved to `lib/wire.ts` — no
imports, no runtime — so a host can depend on the vocabulary alone.

Two more seams and one guard:

- `lib/navigation.ts` holds the href builders behind a `NavigationDriver`, so
  a host addresses its own URL space. The app's half — the hash parser and the
  live route, which attach window listeners at module scope — stays in
  `router.svelte.ts` and is pruned out of the package: rendering a Symbol view
  must not install a hash router in somebody else's application.
- `lib/theme.css` carries the design tokens and maps Svelte Flow's `--xy-*`
  variables onto them, so a host never sees library defaults. Dark now also
  answers to a bare `[data-theme]`, which is how `<CodegraphUi theme>` themes
  a container rather than the document.
- `scripts/check-ui-package.mjs` prunes the app's shell, resolves the
  extensionless specifiers svelte-package leaves behind, and asserts that
  nothing but `lib/adapter.js` reaches the network.

The search box, its keyboard and its panel are one component now
(`SearchPalette`), because splitting them is what breaks a palette.

`__tests__/ui-package.test.ts` mounts the three screens from the package entry
against a mock adapter in jsdom; it runs as a second vitest project so the
`browser` resolve condition it needs cannot reach the engine's suites.

Versioned with the engine. Prepared, not published: `private: true` is the
guard and `pack-npm.sh` only packs a tarball under CODEGRAPH_PACK_UI=1.

Colby McHenryandClaude Opus 5 62e0a89b0e feat(ui): the Flow strip — how one symbol reaches another, one card per hop (CG-50)
Ask "how does execute reach getFile" in the search box and the viewer draws the
call path between them, left to right, opening every card at the exact line that
makes the next call. Dynamic-dispatch hops are dashed and name the site they
were wired at; "Read as flow" turns a trail walked by hand into the same strip.

The path finder is NOT new. `codegraph_explore` already leads its answers with
the longest call chain among the symbols an agent named, and a viewer that drew
a different path would get the two quoted against each other in a review. So the
search moved out of `ToolHandler` into `src/graph/named-symbol-flow.ts` and both
callers ride it — same tokens, same overload rules, same synthesized edges. What
stayed behind in `tools.ts` is the prose.

A pinned from/to question is the same search with two options changed, because
both ends being named is the evidence explore's one-unnamed-bridge cap stands in
for: it bridges freely, keeps twelve candidates per endpoint instead of six
(the CLI's own `main` sorts seventh of ten), and searches from both ends at once
— identical paths to the one-way walk on twelve measured pairs, 3-6x faster.

`/api/flow` is deliberately the one endpoint with no cache: its cards carry
source read from disk, and a drift verdict changes without the index changing.

Verified on this repo (`execute` to `rowToFileRecord`, 8 hops; `main` to
`resolveOne`, 7) and on a fresh excalidraw index, where `mutateElement` to
`renderStaticScene` crosses callback, react-render and jsx-child hops and lists
exactly the hops `codegraph_explore` prints.

Colby McHenryandClaude Opus 5 87afc50e76 feat(ui): the search palette, entry points and a trail that survives the URL (CG-45)
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.

Colby McHenryandClaude Opus 5 5cecaabfc2 feat(ui): the Symbol view — callers, gutter-ported source, line-anchored callee rail (CG-44)
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.

Colby McHenry a72f22a6d3 feat(ui): scaffold the codegraph ui viewer as a Svelte 5 + Vite workspace (CG-40)
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.
