Colby McHenry ad91c8fdd8 feat(ui): classify code from the engine's own tree-sitter parse, retiring Shiki (CG-57)
The viewer ran a second highlighter over source the engine had already parsed
with a real grammar: Shiki, plus 56 pruned TextMate grammars shipped in
dist/textmate/. The classification now comes off that tree instead, so a file is
read by exactly the grammar that decided what its symbols are.

The swap is complete rather than flagged: @shikijs/core, @shikijs/engine-javascript
and @shikijs/langs are off the dependency list, scripts/prune-grammars.mjs and
`npm run build:textmate` are deleted, and check-ui-build.mjs asserts the
tree-sitter grammars in dist/extraction/wasm instead of dist/textmate.

The wire contract is unchanged — `[classId, text]` pairs with the class names
alongside — so the viewer's decoder and code blocks did not have to be rewritten.
Two classes are added to the six: `type` (a named type reference, painted at
plain ink) and `def` (the name a definition declares, weight 600), the latter
taken from the extractors' own definition tables so it cannot drift from what
indexing calls a definition.

Three differences are not cosmetic:

* Interpolations (`${…}`, `#{…}`, `$"{…}"`, f-strings) are classified as code,
  not as string. The call-site overlay refuses to claim a token classed string,
  so calls written inside interpolated strings now link.
* Built-in type words are emitted whole and classed `type` in every language.
  The grammars disagree about whether `string` is a type_identifier or an
  anonymous token inside a predefined_type, and TextMate scoped them
  inconsistently too.
* 3 000 lines of TypeScript cost 24-41 ms instead of ~700 ms.

Given up deliberately: Liquid, Razor, YAML, Twig, XML and .properties render
plain. .svelte/.vue/.astro are classified through their <script> blocks, the same
delegation the SFC extractors do. Pulling html/css/vue out of tree-sitter-wasms
would cover them, but those ABI-13 builds are the known cause of shared-WASM-heap
corruption for every other language in the same process.

Measured parity, per-language before/after screenshots and the reproduction
recipe: docs/design/cg57-highlighting-parity.md.

Colby McHenry 8ac0138940 feat(ui): copy the flow or the map as an image, for a PR comment or a README (CG-55)
"Copy image" and "Download SVG" on the Flow strip's header and in the Map's
side panel. The image is the distribution loop: a flow pasted into a review, a
map pasted into a README, read by somebody with no viewer open.

The exporter serialises the LAYOUT OBJECT rather than scraping the DOM — no
html-to-image, no foreignObject, no new dependency. buildFlowLayout and
buildMapLayout already compute every rectangle, port and curve before a
component renders, so the image and the screen come from one piece of
arithmetic and cannot drift apart, and the whole exporter is a pure function a
test runs with no browser. Output is presentation-only SVG (rect, line, path,
polygon, text, tspan, clipPath) — no script, no external reference, no data:
URL — which is what GitHub's sanitiser accepts in a README.

Light theme is forced whatever the viewer is set to: a dark strip on GitHub's
white comment background reads as a mistake, not a preference. 24px of paper
around the drawing, a caption naming the path or the root at the bottom left,
a CodeGraph mark at the bottom right.

Fonts travel as family stacks, not bytes (spec). An SVG loaded as an image may
not fetch a webfont, so a raster falls back to the platform's own monospace —
every fallback in the stack advances at ~0.6em like IBM Plex Mono, so the code
grid survives and only the letterforms change. Text is truncated
arithmetically with an ellipsis and clipped as well, so a wider fallback
cannot spill a source line out of a card.

`scale` multiplies only the root width/height while the viewBox stays in CSS
pixels, so the raster draws an image whose intrinsic size is already 2x
instead of upscaling a 1x bitmap. The clipboard write uses the ClipboardItem
promise form (Safari discards the gesture across an await) and falls back to
downloading the PNG, saying which happened rather than claiming a copy it did
not make.

Measured on this repo: execute -> rowToFileRecord (8 hops) exports 3690x253
CSS px, 491 kB PNG at 2x / 38 kB SVG; the 16-module map reproduces the canvas
exactly — 16 boxes, 52 links, 9 layer rules, both band labels, and with
src/index.ts selected 15 links and 4 dimmed boxes.

Colby McHenryandClaude Opus 5 94f4e287e6 feat(ui): entry points — routes, executable files and tests as flow starting points (CG-54)
`#/entry` answers "where does anything start" at full length, and turns any row
that names a symbol into a flow.

Server. `/api/entrypoints` gains `frameworks` (from `getDetectedFrameworks`), a
`tests` list, a `routes` limit of its own, and a cache keyed on the index build
— nothing here is read from disk, so unlike `/api/source` a cached answer cannot
be stale about drift. `routes.items` is now a `WireList` like every other list on
the payload.

Routes carry where the URL is REGISTERED as well as where it is served:
`getRoutingManifest` selects the route node's id, file and line, and
`buildRoutes` splits the verb off the name against a fixed list (never "the
first word", which would take the head off a file-routed `/blog/[slug]`). All
four payroll-go routes register in one router file and three are served from
another — group by the handler file and one router becomes two groups plus an
orphan.

`isTestFile` is split into `isTestPath` (test filename and directory
conventions) + the non-production catch-all, byte-identical at every existing
call site. The Tests list uses the narrow half: an example, a benchmark or a
fixture is off-target for ranking but is not a test, and a heading that says
"Tests" must not quietly count them. Tests rank by REACH — distinct other files
touched — because Go, Rust and Java put test work inside functions where a
module-level-calls ranking sees nothing. Two read-only engine queries make that
affordable: `getFileReachCounts` (the mirror of `getFileDependentCounts`, driven
from `nodes` by path so the cost follows the files asked about rather than the
edge table) and `getFileNodes`.

Viewer. `ui/src/lib/entry-model.ts` folds the four lists into file groups —
pure, and `panel.rows` stays exactly the sections it draws. `EntryView` +
`EntrySection` render them with the caller rail's `.filegroup` / `.row` shapes
rather than a second visual language for the same idea. A row that names a
callable symbol carries a `Flow ›` chip; the other end is typed or picked with
`→ here` on another row. File and test rows carry none: `/api/flow` searches by
name, and a file has none the path finder can look up.

A project with fewer than three resolvable routes gets no Routes heading at all,
not an empty one. Typing into the search box now also returns matching entry
points under their own heading below the symbol matches, so a URL comes back
with its handler attached; rows already in the results are dropped.

Colby McHenry dc7f1e590e feat(ui): where the graph stops — the Flow strip's dynamic-dispatch end cap (CG-51)
A flow that does not reach what it was asked about now ends in a cap instead
of in silence: the dispatch form that ended it, the line, the static key when
the source spells one out, the candidate runtime targets as clickable rows,
and the name-only matches under 0.6 the search refused to follow. A flow that
does reach its destination never shows one.

The verdict is lifted out of `ToolHandler` into
`src/graph/dynamic-boundary-report.ts` and both callers render it —
`codegraph_explore`'s prose and `/api/flow`'s `WireFlowBoundary` — the same
move `named-symbol-flow.ts` made for the path finder, and for the same reason:
a reader holding the strip and the MCP answer must not be told two different
things. The explore prose is unchanged, byte for byte.

When nothing connects at all and a dispatch site explains why, the strip is
that site: one card opened at the line where the static path ends, plus the
cap. When nothing explains it, no stopping point is invented.

Colby McHenry ecd6e1cd15 feat(ui): live refresh and drift banners — the viewer keeps up with the project (CG-53)
`GET /api/events` is a server-sent-event stream the viewer holds open for the
life of the page. Two signals, two things the browser could not know:

  changed  source files touched on disk, before any sync — the drift banner
  index    the graph moved, naming what the sync re-indexed — the live refresh

The server WATCHES and never syncs: the project tree through the engine's own
FileWatcher with a notify-only syncFn, the index through one non-recursive
fs.watch on the data directory settled at 400 ms. Both start with the first
subscriber and stop with the last, so a viewer nobody has open costs no watch
descriptors. Nothing polls, on either side.

Drift is now parity with codegraph_node (#1474) rather than an absence.
`/api/source?ondrift=current` serves a drifted file's CURRENT bytes flagged
`showing: 'current'`, and the three screens that can say so switch off
everything anchored to the old line numbering — gutter ports, call-site links,
call arcs, the callee rail's anchoring — while keeping the source. The banner is
paper-2 with a hairline rule, never amber: amber belongs to the untested badge.

Also fixes a stale read this exposed. A long-lived reader holds an LRU of nodes
by id that only its own writes invalidate, so `/api/node/<id>` kept answering
with a symbol another process's sync had deleted while `/api/search` beside it
said it was gone. GraphSession now drops the read caches when the database (or
its WAL) has been written, and the Symbol view follows a symbol whose id changed
because an edit above it moved its start line, carrying the trail across.

Measured on a live viewer: banner 360 ms after a save, toast 440 ms after
`codegraph sync` returns, 0 requests in 4 idle seconds, and the client gives up
reconnecting after ~90 s with "Not live" rather than hammering a dead port.

Colby McHenryandClaude Opus 5 bd99c5e99a feat(ui): the whole file — full source with gutter ports and intra-file call arcs (CG-52)
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.

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 6d0f60f32c feat(ui): the Map — the repository at module granularity, layered from the graph (CG-49)
`GET /api/map` rolls the whole edge table up to module granularity in one
`GROUP BY`, and the Map tab draws it: one box per directory, dependencies
pointing down, nothing placed by hand.

Two decisions carry the screen.

The vertical order rests on each link's `declared` weight — the edges resolved
through an import, a qualified name, an inheritance clause or a typed receiver —
not on its raw count. Bare name matching resolves `run`, `push` and `finish`
across unrelated directories, and layering on raw counts put `src/db` directly
under `src/bin` on this repository's own index. On declared edges the same data
reproduces the pipeline CLAUDE.md describes, with a third of the mutual pairs.
When too few links carry a declared edge to describe a project, the layout falls
back to raw counts and the side panel says so.

And the aggregation is a single scan. Grouping by the symbol names as well as
the modules costs nothing extra — the join is what is expensive — so one query
yields both the link weights and the tooltip's symbol pairs. Measured against
this index inflated to 800k edges: 1.28s for one scan against 1.89s for two,
which is the difference between meeting and missing the cold budget on a
ten-thousand-file repository. Cached answers come back in ~3ms.

Nothing is dropped silently: thin links are hidden until a module they touch is
selected and counted in the panel, uncertain references are excluded from every
number on screen and the total is printed, and mutual dependencies, module loops
and file-level circular imports are listed rather than straightened away. An
edge that still points up after layering is drawn dashed on selection instead of
being reversed or removed.

The layout — cycle-breaking, longest-path layering, barycenter ordering, ports —
is a pure function of the payload in `ui/src/lib/map-model.ts`, so the tests
toggle and the selection cost no round-trip and the same project always draws
the same picture. Svelte Flow supplies pan, zoom and fit; never a layout.

Colby McHenryandClaude Opus 5 58dad12f89 feat(ui): the File view — outline in source order between two dependency rails (CG-46)
Clicking a file path now opens the file itself: what reaches into it, its
symbols in source order, and what it reaches.

The two rails count DEPENDENCIES, not import statements. The prototype drew
`imports` edges; on this repo `src/graph/traversal.ts` imports two files and
depends on four, because it reaches the LRU cache through a call no import
names. A rail headed "Imports 2" would be quietly wrong about what changing the
file would touch, which is the only question the screen answers — so the rails
read `getFileDependencies` / `getFileDependents` and merge the import rows in
for the symbol names. Imports that resolved to nothing indexed keep their own
section rather than vanishing.

The outline is windowed above 250 rows against a fixed 28px row: this repo's
own fixtures hold a 1,681-symbol `.d.ts`, and paging it would hide the one
thing an outline is for. `src/mcp/tools.ts` draws its 135 rows whole.

`/api/file` gains `topLevel.calls` — module-level calls out of the file node —
so a file that RUNS something offers the badge that opens it as a symbol, the
only place code belonging to no symbol can be read.

File results in the search palette and the entry-point list now land here
rather than on the file node's Symbol view.

Colby McHenry 2ad836d935 feat(ui): highlight source server-side with a near-monochrome Shiki theme (CG-43)
The viewer's code block stops lexing with a hand-rolled dialect table and
reads real TextMate grammars instead, run once in `/api/source`.

Three things make that safe to depend on:

* Highlighting never fails a request. A missing grammar, an oversized
  slice, an ESM import that did not resolve — every one of them answers
  `engine: 'plain'` with a reason and the source still goes out.
* Identifiers survive whatever token boundaries a grammar chose. Every
  code token is split into identifier runs before it goes on the wire, so
  the graph's call-site overlay claims a token the highlighter produced
  rather than re-cutting the line. `assignRefs` now matches on a token's
  text rather than on the class a grammar gave it, so a language that
  scopes type names as `storage.type` still links.
* The theme classifies rather than colours: its foregrounds are sentinels
  the server maps back to class names, and the viewer paints them from
  CSS custom properties — one token stream serves light and dark with no
  refetch, and the ramp lives only in app.css.

Comments move from --ink-3 to a new --code-comment. --ink-3 measures
3.46:1 on paper and 3.00:1 on the hot-line tint, both under AA for 12.5px
text; --code-comment is the smallest step along the same ramp that clears
4.5:1 on every background a code line can have, and stays quieter than
the strings and numbers above it.

Shipping: @shikijs/core and @shikijs/engine-javascript are runtime
dependencies (no wasm, no native module); @shikijs/langs stays a
devDependency and `npm run build:textmate` writes only the closure the
engine's 40-odd languages reach — 56 grammars, 2.6 MB, against 11 MB for
all 722. check-ui-build.mjs asserts the tree after every build and inside
every release archive.

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 e9596af1cf fix(ui): keep a callee row hidden until the rail has been measured (CG-44)
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.

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.
