…nsitivity (colbymchenry#327)

Drop the no-op try/catch around insertNode.run, and lowercase the Windows
SENSITIVE_PATHS entries so validateProjectPath's case-insensitive check
actually blocks c:\windows. Adds a validateProjectPath test (POSIX +
Windows-gated); the Windows-gated case was validated on a real Windows 11 VM.

Closes colbymchenry#327

Validate projectPath in getCodeGraph so MCP clients can't open a codegraph in a
sensitive system directory. Guarded with existsSync so nested/not-yet-created
sub-paths still resolve up to the default project (preserves issue colbymchenry#238). Adds
MCP-handler rejection tests (POSIX + Windows-gated); validated on a real
Windows 11 VM.

O_NOFOLLOW is undefined on Windows (libuv ignores it), so the bitwise-OR
silently dropped it and markSessionConsulted would follow a pre-planted symlink
at the tmp marker path — the CWE-59 gap colbymchenry#280 closed on POSIX but not Windows.
Add a cross-platform lstatSync isSymbolicLink() refuse-check before openSync
(O_NOFOLLOW stays as the atomic, TOCTOU-free guard on POSIX). The existing
Session-marker-symlink-resistance test now passes on Windows.

…ry#286)

Add a PPID watchdog to the MCP server so a `codegraph serve --mcp` child terminates when its host (Claude Code, opencode, …) is force-killed — OOM killer, `kill -9`, container teardown — and the stdin close handlers don't fire. The child would otherwise linger indefinitely, holding inotify watches, file descriptors, and the SQLite WAL.

Also propagates the host PID across the `--liftoff-only` re-exec (CODEGRAPH_HOST_PPID) so the watchdog reaps the orphan on the from-source path too, not just the bundled launcher. Poll interval is CODEGRAPH_PPID_POLL_MS (default 5000ms, 0 disables).

…retrieval improvements (colbymchenry#365)

* feat(resolution): close dynamic-dispatch coverage holes (callback synthesis + django ORM)

Static tree-sitter extraction misses calls whose target is computed or indirect,
so flows through callbacks, observers, and descriptors were absent from the graph.

- callback-synthesizer.ts: whole-graph pass after base resolution. Detects
  registrar/dispatcher channels (field-backed observers + string-keyed
  EventEmitters), correlates registration sites, and synthesizes
  dispatcher->callback `calls` edges (provenance:'heuristic'). Records the
  registration site (registeredAt) in edge metadata. Precision guards: named
  handlers only, registrar-name match, event fan-out cap.
- frameworks/python.ts + resolution/{index,types}.ts: claimsReference hook +
  django ORM resolver (_iterable_class -> ModelIterable.__iter__).
- extraction/tree-sitter.ts: extract named nested functions so inline named
  handlers become linkable nodes.

trace(mutateElement, triggerRender) and trace(_fetch_all, execute_sql) now
connect; node count stable (no explosion).

* feat(mcp): self-sufficient flow output + fix explore budget regression

- Surface synthesized-edge evidence in trace, the node trail, and context call
  paths: a dynamic-dispatch hop now shows "callback via onUpdate @App.tsx:3148"
  with the registration site inline (and trace inlines each hop's call-site
  source line) -- the exact glue agents previously Read/Grep'd to reconstruct.
- Fix non-monotonic explore output budget: the 500-5000 file tier capped
  maxCharsPerFile at 2500, BELOW the <500 tier's 3800, so on god-file projects
  (excalidraw's 415 KB App.tsx) one explore returned <1% of the file and forced
  a Read. Raised to 6500/file, 28000 total.
- Stop explore from inviting Read: truncation/trim notes said "use Read for
  more"; they now steer to another codegraph_explore and treat returned source
  as already Read.

Measured on excalidraw: best-case flow answer went from 5 reads / 131s to
0 reads / 73s with ~3-4 codegraph calls.

* chore(agent-eval): coverage probes, block-read hook, and design docs

Dev-only validation harness for the dynamic-dispatch coverage work:
- probe-{trace,node,context,explore}.mjs: drive MCP tools against a built index
  without a full agent run.
- block-read-hook.sh + hook-settings.json: PreToolUse experiment that denies
  source Reads to measure codegraph sufficiency (forced Read-0).
- docs/design/: callback-edge-synthesis + dynamic-dispatch-coverage playbook.

* feat(resolution): bridge React boundaries — re-render + JSX child synthesis

Closes the two dynamic-dispatch hops that broke "state mutation -> on-screen
render" flows in React apps. Both are call-invisible (React-internal) but the
code between them is fully call-connected, so one synthesized edge each makes the
whole flow trace end-to-end.

- reactRenderEdges: setState(...) re-runs the component's render(). For each
  class with a render method, link sibling methods calling this.setState ->
  render. The setState gate keeps it to React class components.
- reactJsxChildEdges: a component that returns <Child .../> mounts Child. Link
  parent -> each capitalized JSX child, resolved to a component/function/class
  node (the resolution gate drops TS generics like Array<Foo>). File-oriented,
  capped per parent.
- Surface both in synthEdgeNote (trace + node trail) and context call-paths.

Validated on excalidraw: trace(mutateElement, renderStaticScene) now connects in
6 hops across callback -> react-render -> jsx-child; 1 + 46 + 280 synthesized
edges, node count stable (no explosion). Partial coverage is worse than none:
react-render alone raised agent reads (revealed a hop it then drilled); adding
the jsx hop closed the flow and dropped reads to 0-1.

* docs(claude): retrieval performance contract + coverage validation methodology

Add a "Retrieval performance & dynamic-dispatch coverage" section so future
changes/PRs don't silently regress agent retrieval:
- the explore call+output budget table by repo size, with the monotonic-per-file
  invariant (the bug that started this: <5000 tier's 2500 < <500 tier's 3800).
- the "partial coverage is worse than none" principle.
- the required validation methodology (small/medium/large x >=3 prompts per
  language x framework; deterministic probes + agent A/B; pass bar).
- the Excalidraw worked example (before/after numbers) as the template to
  replicate for every language/framework.

* docs(claude): use full n=4 measured range in Excalidraw worked example

Best run 0 Read/3 cg/76s; typical ~1 Read/~4 cg; occasional over-drill outlier.
Report the range, not a single run — run-to-run variance is large.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(mcp): steer flow questions to codegraph_trace first (tightens variance)

codegraph_trace was absent from every steering intent map — all three guidance
files routed "how does X reach Y" to context+explore, never to the trace tool.
So agents used trace only by chance; when one didn't, it floundered
reconstructing the path with search+callers (an 18-call run vs ~6 for trace-users).

Add codegraph_trace to the intent map + a "flow" common chain (trace from->to
FIRST = the whole path in one call, then ONE explore for bodies) across all three
synced files (server-instructions, instructions-template, .cursor rule).

Validated on excalidraw (hard "to the screen" Q, n=4 before/after):
- call count 3-10 -> 3-4 (over-drill outlier gone)
- duration 64-112s -> 51-74s
- trace adoption 3/4 -> 4/4; search+callers path-reconstruction -> 0
- fully-clean runs (0 Read, 0 Grep) 0/4 -> 2/4; best 3 cg / 0 / 0 / 51s

* feat(resolution): Vue SFC template coverage (events + kebab components)

The .vue extractor only parses <script>, so template usage is invisible —
handlers and kebab child components used only in <template> have no edge. Add a
vueTemplateEdges channel (scoped to the <template> block of .vue files):
- event bindings: @click="onClick" / v-on:submit="save" -> handler method/function
  (skips inline arrows and $emit; resolves same-file first to avoid cross-app
  mis-match in monorepos).
- kebab child components: <el-button> -> ElButton (PascalCase children like
  <VPNav/> are already caught by the JSX channel via the SFC component node).

Surface vue-handler in synthEdgeNote (trace/node trail) + context call-paths.

Validated on vue repos (reindex, no node explosion):
- vue-handler edges: vitepress 15, vben 404, element-plus 603 — all precise
  (code-login @submit -> handleLogin, register @submit -> handleSubmit, ...).
- callers(handleLogin) now includes the login component (was 0); each monorepo
  app's login resolves to its own same-file handler.
- composition: PascalCase + kebab work; element-plus's el-/filename naming
  (el-button -> button.vue) is a known library-prefix limitation.

* docs(playbook): record Vue validation in coverage matrix + limits

Vue / Nuxt row → ✅ template events + composition (vitepress S / vben M /
element-plus L); 🔬 reactive→render (vue-core Proxy runtime, deferred).

§7: Vue results + the two real limits — composable-destructure handlers
(@click="closeSidebar" from useSidebarControl, a data-flow frontier) and
prefix-convention kebab (el-button→button.vue). Agent reads dropped in every
size; strongest where handlers are local functions.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(resolution): resolve Vue composable-destructure template handlers

@click="closeSidebar" where `const { close: closeSidebar } = useSidebarControl()`
previously didn't resolve — the handler is a destructured composable return, not a
local fn node. Now: parse the SFC's `use*()` destructures into alias→{composable,
key}, and for an unresolved template handler follow alias → composable → the
returned member (`close`) defined in the composable's file. Precise-only: no
fallback to the composable itself (the component already has a static useX() call
edge), so we add an edge only when the specific returned fn is found.

Validated: vitepress Layout @click→close / @open-menu→open (in composables/
sidebar.ts); sidebar-flow agent run dropped 6→0 reads (best case). element-plus's
fallback-only matches correctly drop to 0; node counts stable; direct handlers
(vben handleLogin) unaffected.

* feat(extraction): extract function-valued properties of exported-const objects

`export const actions = { default: async () => {...} }` (SvelteKit form actions,
and general JS handler/route/reducer maps) left the arrow functions unextracted —
the walker skips object-literal functions (deliberately, to avoid inline-object
noise like `ctx.set({...})`). So an action's body (and its calls) was invisible.

Now: for an EXPORTED const whose initializer is an object literal, extract each
function-valued property (arrow / function expression) as a function named by its
key and walk its body. extractFunction gains a nameOverride so ONLY this explicit
path names pair-arrows — inline-object arrows reached by the general walker still
fall through to the <anonymous> skip, so no noise returns. JS/TS-gated.

Validated: fixtures extract the actions + walk bodies (default→helper, default→
api.post resolve); SvelteKit detection doesn't break it. Blast radius tiny:
excalidraw +1 node, Python (django) +0, Vue repos +0, realworld +11 (the actions).

Known residual: a `$lib`-alias namespace-member call (`api.post`) from an extracted
action node doesn't resolve even though the same alias resolves for `load` — a
deeper resolver interaction, separate from this extraction change. Local/relative
calls from actions connect fine.

* docs(playbook): record Svelte validation (already well-covered) + actions fix

Svelte/SvelteKit row → already strong (template calls/composition/namespace/load);
+ exported-const object-of-functions extraction. Lesson: measure before assuming
a hole — modern Svelte barely uses on:click={fn}; Svelte needed far less than Vue.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(resolution): connect Express inline arrow route handlers to their services

The Express resolver created route nodes but linked handlers via a single regex
whose `[^)]+` broke on inline arrows — so `router.post('/x', async (req,res) =>
{...})` (the dominant modern pattern) connected to NOTHING, and the anonymous
handler's body (the actual request→service flow) was lost. The whole inline-handler
API was unreachable: e.g. realworld's `POST /users/login` route → 0 edges.

Now: match the route head, span the full call with a string-aware balanced-paren
scan, and for an inline arrow handler extract its body's calls (string-aware brace
scan) and attribute them to the route node as `calls` edges. A RESERVED denylist
drops res/req/builtin methods (json, next, status, ...) to keep only business calls.
Named-handler routes keep the existing reference behavior.

Validated: realworld POST /users/login → login (auth.service); 19 precise
route→service edges (was 0) — POST /articles→createArticle, .../favorite→
favoriteArticle, etc., no json/next noise. ghost +65 inline-handler edges. No node
explosion (ghost 40767, parse 3394 unchanged). Framework-scoped: zero blast radius
off Express.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs(playbook): record Express validation (inline-handler fix)

Express/Koa row → resolver already handled named handlers; the real hole was
inline arrow route handlers (router.post('/x', async (req,res)=>{...})) — fixed:
route→service body calls (realworld 19 / ghost 65 edges, no explosion). Agent A/B
muddied by repo size (realworld tiny) / complexity (ghost layered API). Lesson
inverse of Svelte: Express's dominant pattern WAS the uncovered one.

* docs(playbook): record NestJS validation (already well-covered)

NestJS row → resolver handles @decorator routes; DI controller→service
(this.svc.method) resolves correctly at scale (immich: addUsersToAlbum→addUsers,
etc.). Agent A/B: codegraph eliminated Grep (0 vs 3). No dynamic-dispatch hole.
Surfaced a general hygiene gap (not NestJS): committed dist/ build output gets
indexed (no default build-dir ignore) — narrow (real apps gitignore dist/),
deferred as a core-indexer follow-up.

* feat(resolution): Rails RESTful resources routing → controller#action

The rails resolver only saw explicit `get '/x' => 'c#a'` routes, so apps using
the dominant `resources :articles` / `resource :user` RESTful routing had ZERO
route nodes (realworld + spree: 0 routes despite full routes.rb files). The whole
request→controller flow was disconnected.

Fix (frameworks/ruby.ts):
- extract: expand `resources`/`resource` into their REST actions (only/except
  filters; pluralize the singular `resource :user` → users_controller), emit a
  precise `controller#action` ref per action. Explicit routes now also reference
  `controller#action` instead of a bare ambiguous `action`.
- resolve: new `controller#action` pattern → the action method in
  <ctrl>_controller.rb (file convention + controller-class fallback).
- claimsReference: claim `controller#action` refs so resolveOne's pre-filter
  doesn't drop them before resolve() runs (same hook the django ORM work needed —
  these refs name no declared symbol).

Validated: realworld 0→16, forem 0→635 precise route→action edges (GET /articles→
index, resource :user→users#show, etc.), pluralization correct, no node explosion
(route nodes proportional to resources). Agent A/B (forem, large): with codegraph
1-4 reads / 0 grep / 47-53s vs without 4-5 reads / 2-3 grep / 66-85s. Framework-
scoped (zero blast radius off Rails). Residuals: Rails Engine routing (spree
mounts an engine), ActiveRecord dynamic finders (metaprogramming frontier).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(resolution): Spring bare + class-prefixed route mappings → controller method

The Spring resolver required a string path in the mapping regex, so BARE method
mappings (`@PostMapping` with the path on the class-level `@RequestMapping`) were
missed — the dominant multi-method-controller pattern. realworld's two-action
ArticleFavoriteApi only linked one method; halo had 28 routes for 2444 files.

Fix (frameworks/java.ts):
- Treat class-level `@RequestMapping` as a PREFIX (not a bogus route) and join it
  onto each method's path.
- Match verb-specific mappings (@GetMapping/@PostMapping/...) BARE or with a path.
- Also handle method-level `@RequestMapping(value=..., method=RequestMethod.X)`
  (older style) — restored after an initial cut dropped it (mall regressed 292→1;
  caught by the regression check).

Validated: realworld 13→19, mall 246 (all precise, class prefix joined:
GET /subject/listAll→listAll, POST /articles/{slug}/favorite→favoriteArticle +
DELETE→unfavoriteArticle), no node explosion. DI controller→service resolves
(article→findBySlug, updateArticle→canWriteArticle). Agent A/B (mall cart flow):
with codegraph 0 reads/0 grep vs without 2/2. Residuals: halo's complex custom
patterns (9/29 resolve); Spring Data JPA derived queries (metaprogramming frontier).

route-count regression check. Residuals: halo custom patterns, JPA derived queries.

* feat(resolution): Django DRF router.register → ViewSet

Django's ORM (_iterable_class, prior work) and URL routing (path/url/as_view→view)
were already covered. The remaining hole: DRF `router.register(r'articles',
ArticleViewSet)` — the core CRUD endpoints — wasn't extracted (only path()/url()),
so a DRF API's main resources connected to nothing (realworld's ArticleViewSet:
0 callers).

Fix (frameworks/python.ts): match `.register(r'prefix', XViewSet)` → route→ViewSet
class. The STRING first arg distinguishes DRF router.register from
`admin.site.register(Model, Admin)` (model class first arg); View/ViewSet suffix
keeps it to viewsets. The ViewSet class resolves via the existing View/ViewSet
pattern.

Validated: realworld VIEWSET /articles → ArticleViewSet (was 0). Narrow in corpus
(realworld 1 router; wagtail=path, saleor=GraphQL) but real for DRF-router APIs.
Agent A/B (wagtail Page flow, medium): with codegraph 4-7 reads / 1-4 grep / 58-81s
vs without 7-9 reads / 6 grep / 82-86s. No regression (wagtail/saleor route counts
unchanged — purely additive). Residuals: signals, DRF inherited viewset actions,
GraphQL resolvers.

* feat(resolution): Laravel route → precise Controller@method (not bare action)

extractLaravelHandler discarded the controller: `Route::get([UserController::class,
'index'])` and `'UserController@index'` both emitted a BARE `index` ref. With the
route in routes/api.php (not the controller file), name-matching mis-resolved every
common action to the WRONG controller — realworld's GET user → ArticleController.index
(should be UserController), GET articles/feed → ArticleController (should be
FeedController), etc. The routes existed but pointed at the wrong handler.

Fix (frameworks/laravel.ts): emit precise `Controller@method` (array + string
syntax, namespace-stripped) and `claimsReference` it so resolveOne's pre-filter
doesn't drop it before Pattern-4 resolveControllerMethod runs (the recurring hook,
also needed by django ORM + Rails routing).

Validated: realworld all routes now resolve to the correct controller; bookstack
267/332 precise (GET pages → PageApiController.list, array syntax). No node
explosion. Agent A/B (bookstack page-view, large): with codegraph 2-3 reads / 1-2
grep / 51-60s vs without 4-6 / 3-5 / 60-74s. Residuals: firefly's fluent
->uses()/['uses'=>...] handler format (3/568 resolve), Eloquent dynamic finders.

* feat(resolution): Gin/chi routes on group vars (any receiver, not just r/router)

The route regex matched only `(router|r|mux|app|e).METHOD(...)`, but real Gin/chi
apps route on GROUP variables — `v1.GET`, `PublicGroup.GET`, `userRouter.POST` —
so group-routed apps connected almost nothing: gin-vue-admin had 4 routes for 625
files. Broaden the receiver to ANY identifier; the verb + string-path + handler-arg
gates keep it route-specific (e.g. `http.Get(url)` has no handler arg, so it's
excluded).

Validated: gin-vue-admin 4→259 routes, 257 resolve precisely (POST createInfo→
CreateInfo, GET getInfoList→GetInfoList); realworld stable 24→25 (no regression);
no garbage (257/259 resolve, not false positives), node count proportional. gitness
(chi, custom handlers) is a residual (26/321). Inline `func(c *gin.Context){...}`
handlers still lose their body (anonymous, like Express was) — separate residual.

cleanest backend win yet. Residuals: inline func handlers, gitness chi custom.

* feat(resolution): ASP.NET feature-folder detection + bare attribute routes

Two holes left ASP.NET apps disconnected:
1. detect() only fired on a /Controllers/ dir, root Program.cs/Startup.cs, or a
   .csproj (which often isn't in the indexed source set). Feature-folder apps
   (realworld: Features/*/FooController.cs, subdir Program.cs) were never detected
   → 0 routes despite a full set of controllers. Broaden: scan Controller/Program/
   Startup .cs source for ASP.NET signatures ([ApiController]/[Route]/[Http*],
   ControllerBase, MapControllers, WebApplication, Microsoft.AspNetCore).
2. The attribute regex required a string path, so BARE [HttpGet] (route on the
   class [Route("[controller]")]) was missed — eShopOnWeb was 24 bare / 2 string.
   Match bare-or-with-path + join the class [Route] prefix (like the Spring fix).

No claimsReference needed: ASP.NET attribute routes are co-located IN the controller
with the action, so the bare method-name ref resolves same-file.

Validated: realworld 0→19 routes (all precise: GET /articles→Get, POST /articles→
Create, class prefix joined), eShopOnWeb 9→33. Route→action correct + co-located.

* feat(resolution): Flask/FastAPI route holes + Python builtin-name handler guard

Three fixes that connect the request→route→handler flow for Flask and
FastAPI. Validated S/L: fastapi-realworld 12→20, flask-microblog 6→27,
Netflix dispatch 290/290 (100%), redash decorator routes 6/6; canonical
flows trace end-to-end (login→get_user_by_email, create_user→from_dict).

- Flask: the route regex required `def` immediately after `@x.route(...)`,
  so an intervening decorator (@login_required, @cache.cached) or stacked
  @x.route lines (one view bound to several URLs) dropped the route.
  Switch to the findHandler scan (match the decorator, then find the next
  def) like FastAPI — skips intervening decorators.
- FastAPI: the path regex `[^'"]+` rejected the empty path `@router.get("")`
  (router/prefix-root routes, frequently multi-line). Allow empty path +
  guard the route name against a trailing space.
- Python builtin-name guard (src/resolution/index.ts): a handler named
  after a Python builtin method (index/get/update/count…) was filtered by
  isBuiltInOrExternal and lost its route→handler edge. Mirror the
  dotted-method branch's knownNames guard onto the bare branch — a bare
  name a declared symbol owns is a real target, not a builtin call.
  +2 legit edges on realworld, 0 change on the django control (precision held).

Tests: new Flask (intervening/stacked decorator) and FastAPI (empty-path,
multi-line) extractor cases + a Flask end-to-end integration test (a view
named `index` behind @login_required). Also corrects 6 pre-existing stale
Laravel/Rails route-ref assertions surfaced by the suite — they expected
the old bare action name, but the resolvers now emit precise
controller@action / controller#action (from earlier precision commits).
Full suite green (781 passed).

* feat(resolution): Drupal route-handler resolution (claimsReference, single-colon controllers, contrib detection)

The *.routing.yml extractor and _controller/_form resolver existed but two
gaps left most routes unlinked. Validated S/M/L: admin_toolbar 0→14 (14/14),
webform 144/208, drupal-core 536→731/836 (87%); canonical flow traverses
(getAnnouncements ← /admin/announcements_feed); node count unchanged.

- claimsReference: Drupal handler refs are FQCNs (\Drupal\…\Class::method),
  bare form classes (\…\SettingsForm), or single-colon controller-services
  (\…\Controller:method). Only the ::method shape survived resolveOne's
  pre-filter (its member is a known method name); the bare-FQCN forms and
  single-colon controllers were dropped before resolve() ran. Claim FQCN /
  Class:method / hook_* refs (same pattern as Rails controller#action).
- Single-colon controller match: broaden the controller regex from :: to
  :{1,2} and tighten the _form branch to !name.includes(':').
- Detection: detect() only checked composer `require` for a drupal/* dep, but
  a contrib module often has an empty require and is identified only by
  "name":"drupal/<m>" + "type":"drupal-module" (admin_toolbar → 0 routes).
  Broaden to composer name/type + a *.info.yml fallback.

Remaining unresolved is the entity-annotation handler frontier
(_entity_form: type.op) and OOP #[Hook] attributes (Drupal 11 moved ~all
procedural hooks to attribute methods — out of scope here). Tests: contrib
detection, *.info.yml fallback, claimsReference, single-colon controller.
Full suite green (787 passed).

* feat(resolution): Axum chained methods + namespaced handlers

The Axum route extractor used a flat regex that captured only the first
method(handler) of a .route() call and only a bare \w+ handler, so two
dominant Axum idioms broke:
- method chains: .route("/user", get(get_current_user).put(update_user))
  emitted no node for the .put arm — half the API was missing.
- namespaced handlers: get(listing::feed_articles) captured `listing`
  (the module), so the route resolved to nothing.

Rewrite with a balanced-paren scan of each .route(...) call, a route node
per chained method, and last-::-segment handler names. realworld-axum
12→19 routes, 19/19 resolved (every chained PUT/DELETE/POST now present,
feed_articles resolves). Rocket needed nothing (550/556, 99%, attribute
macros); crates.io confirms namespaced axum handlers resolve.

Residual frontier: actix runtime routing web::get().to(handler) (the
dominant actix style, unextracted; attribute macros 35/51). Fix is
Axum-scoped — the attribute/actix/Rocket path is untouched. Tests: chained
methods + multi-line namespaced handler. Full suite green (789 passed).

* feat(resolution): Vapor grouped/RouteCollection routing (was 0 routes on real apps)

The Vapor extractor only matched (app|router|routes).METHOD("path", use:
handler), but real Vapor apps route on a grouped builder inside
RouteCollection.boot(routes:): `let todos = routes.grouped("todos");
todos.get(use: index)` — any var receiver, no path arg (the path is the
group prefix). Every real app tested extracted 0 routes (template,
SteamPress, SwiftPackageIndex-Server, penny-bot, Feather).

Rewrite the extractor:
- any receiver (\w+), not just app/router/routes;
- optional path segments that may be non-string (User.parameter, :id, a
  path constant) — the `use:` keyword discriminates a route from
  Environment.get("X") / req.parameters.get("X");
- a group-prefix map from `let X = Y.grouped("a")` and
  `Y.group("a") { X in }` so a grouped/nested route gets its full path
  (todo.delete(use: delete) -> DELETE /todos/:todoID).

Result: vapor-template 0→3 (3/3, nested path exact), SteamPress 0→27
(27/27), SwiftPackageIndex-Server 0→14 (14/14 handler resolution).
Canonical flow traverses (createPostHandler <- GET /createPost ->
createPostView). Route names now carry a leading slash (GET /users),
consistent with the other frameworks.

Frontier: typed-route enums (SPI's SiteURL.x.pathComponents — handler
resolves, path label only) and closure handlers (app.get("x"){ } —
anonymous). Tests: grouped RouteCollection, self.handler + non-string
segments, use:-discriminator. Full suite green (792 passed).

* feat(resolution): React Router <Route> JSX route extraction

react.ts extracted components/hooks and Next.js file routes but returned
references: [], so React Router <Route> declarations produced no route
nodes or route→component edges. Add <Route> JSX extraction: scan a window
after each <Route (so the nested > in element={<Comp/>} doesn't truncate
the match), pull path="…" + component={C} (v5) or element={<C/>} (v6) in
any attribute order, emit a route node + component reference (resolved by
the existing PascalCase resolveComponent). The <Routes> container is
excluded via the \b boundary.

react-realworld 0→10 routes, 10/10 resolved (/login→Login,
/editor/:slug→Editor, /@:username→Profile). No regression on excalidraw
(9,290 nodes, 46 react-render synth edges intact, 0 false routes). Tests:
v5 component=, v6 element=, <Routes>-container guard. Suite green (794).

Frontier: object data-router createBrowserRouter([{path,element}]) (modern
v6) is object-based not JSX — not covered.

* feat(resolution): actix-web builder-API routing (web::resource / .to(handler))

Actix's attribute macros were covered, but the dominant actix style is the
builder API — web::resource("/path").route(web::get().to(handler)),
web::resource("/").to(handler) (all methods), and App .route("/path",
web::get().to(handler)). The handler is in .to(handler), not get(handler),
so the Axum .route scan extracted nothing — actix-examples had 80
web::resource calls all unlinked.

Add an actix block: scan each web::resource("/path") (bounding its method
chain at the next resource) for web::METHOD().to(h) pairs, fall back to a
direct .to(h) (method ANY), plus the App-level .route("/x",
web::METHOD().to(h)) form. actix-examples 51→128 routes, 35→112 resolved
(GET /user/{name}→with_param, POST /user→add_user). No regression on Axum
(realworld-axum still 19/19). Tests: resource+route, resource direct .to,
App-level route. Suite green (797).

Frontier: web::scope("/api") prefixes not prepended; anonymous .to(|req|…)
closures have no named target.

* feat(extraction): Flutter setState→build synthesis + Dart method body ranges

Two changes that connect Flutter's reactive dispatch:

- Dart method ranges (foundational): Dart models a method body as a SIBLING
  of the method_signature node, so every Dart method node had endLine ==
  startLine (signature only) — body-level analysis (callees, context slices,
  the synthesizer's body scan) saw only `void f() {`. Extend endLine to the
  resolved body in the shared createNode, guarded to only ever extend
  (child-body grammars are a no-op; controls excalidraw 9,290 / django 302
  unchanged).
- Flutter setState→build synthesizer channel (the Dart analog of react-render):
  for each Dart class with a `build` method, link sibling methods whose body
  calls setState( → build. setState re-runs build (Flutter-internal, no static
  edge), so "tap → handler → setState → rebuilt UI" dead-ended at setState.

counter initState→build, books build→BookDetail/BookForm. Widget composition
needs no synthesis — Dart widgets are explicit constructor calls, already
static (compass_app build→ErrorIndicator/HomeButton). Tests: Dart method
spans its body; Flutter handler→build synthesis end-to-end. Suite green (798).

Frontier: MVVM Command/ChangeNotifier dispatch (no setState) + Navigator.push
route-as-widget navigation.

* feat(resolution): Spring Boot Kotlin routing (.kt + fun handlers)

Kotlin had zero framework coverage — no resolver listed kotlin, and the
Spring resolver was languages:['java'] with a .java-only extract gate and a
Java-syntax handler regex (public X name()). Spring Boot Kotlin apps (same
@GetMapping/@RestController annotations, .kt files) extracted 0 routes.

Extend the Spring resolver: languages ['java','kotlin'], accept .kt, and add
a Kotlin `fun name(` alternative to the handler-method regex (Kotlin has no
access modifier; the return type follows the name). Also allow Kotlin class
modifiers (open/data/sealed) in the class @RequestMapping-prefix detection,
and tag route/ref language per file.

spring-petclinic-kotlin 0→18 routes, 18/18 resolved; class @RequestMapping
prefixes join, stacked annotations skipped, DI controller→repo resolves
(showOwner ← GET /owners/{ownerId} → OwnerRepository.findById). Java Spring
unchanged (realworld 19/19 — the Kotlin fun and Java public-X alternatives
are disjoint per language). Jetpack Compose composition already works
(@composable→child are plain function calls). Tests: Kotlin @GetMapping+fun,
class-prefix + stacked annotation. Suite green (800).

Frontier: Ktor inline-lambda routing, Compose recomposition, coroutines/Flow.

matrix's assumed "callback synthesizer" hole isn't real — event-callback
registration (keymap/autocmd/:Connect) is predominantly inline anonymous
closures (corpus ~12 inline vs ~2 named), too rare to synthesize. A/B: 0
read/0 grep with codegraph vs 1 read without. No code change; validated.

* feat(resolution): Play Framework conf/routes → controller routing (Scala/Java)

Play declares routes in an extensionless conf/routes file (GET /computers
controllers.Application.list(p: Int ?= 0)) the file walk never indexed
(isSourceFile requires an extension), so Play apps had 0 route nodes.

- grammars.ts: add isPlayRoutesFile (conf/routes + *.routes), opt it into
  isSourceFile, and map it to the no-grammar (yaml-style) path in
  detectLanguage so the framework resolver extracts it. Narrow match — only
  ADDS Play routes files, never affects other indexing.
- play.ts: a Play resolver — detect (build.sbt/conf), extract (parse each
  METHOD /path Controller.action(args) line, drop package + args), resolve
  (Controller.action → the action method in that controller class),
  claimsReference for the dotted Controller.action handler.

computer-database 0→8 routes, 7/8 resolved (the 1 unresolved is
controllers.Assets.versioned — Play's framework controller, external);
starter 0→4 (3/4). Flow connects request→route→controller→DAO. No-regression
(excalidraw 9,290 / suite unchanged). Tests: routes parse + `->` include
skipped, conf/routes file detection.

Frontier: SIRD programmatic routers (-> include + case GET(p"/x")) + Akka
actor message→handler.

* feat(extraction): C++ inheritance (base_class_clause) + virtual-override synthesis

C/C++ direct dispatch already resolves well (redis 29k / leveldb 1.4k
cross-file calls). Two changes close the C++ virtual-dispatch gap:

- extractInheritance handled base_clause (PHP) but not C++'s
  base_class_clause, so C++ `extends` edges were missing/partial. Add the
  C++ branch (emit an extends ref per base type, skipping access
  specifiers) — leveldb extends 219→298.
- cpp-override synthesizer channel (the C++ analog of react-render): for
  each extends edge, link each base method → the subclass override of the
  same name, so trace/callees from a virtual/interface method reach the
  implementation. Gated to C++, capped per class. leveldb 12 precise edges
  (Iterator::Next/Seek/Prev → MergingIterator), 0 on C (redis) and TS
  (excalidraw). Test: base virtual → subclass override bridge.

Frontier: C callback structs (cmd->proc() → 422-way fan-out, too noisy)
and C++ pure-virtual base methods (declarations aren't nodes, so those
overrides can't bridge). Suite green (804).

* feat(resolution): React Router object data-router + Next.js route precision

- Object data-router (v6.4+): createBrowserRouter([{ path, element: <Comp/> }])
  / { path, Component: Comp } — extract route + component (gated to files using
  the data-router API; requires a component so a stray `path:` field isn't a route).
- Next.js precision: filePathToRoute treated config files (next.config.mjs,
  vite.config.ts) and a `nextjs-pages/` dir (substring of "pages/") as routes.
  Require a real page extension (.tsx/.ts/.jsx/.js), exclude *.config.* and
  _app/_document, and match pages/ + app/ as path SEGMENTS. bulletproof-react
  4 bogus config "routes" → 0.

Frontier: lazy data-router routes (path: paths.x.path + lazy: () => import())
use variable paths + lazily-imported modules — no literal path/named component.
Tests: object-router literal form, config/nextjs-pages exclusion. Suite 806.

* feat(resolution): Flask-RESTful add_resource + tuple methods + broader detection

Three Flask gaps closed (redash Flask-RESTful 6→77 py routes; flask-realworld 0→19):
- Flask-RESTful: api.add_resource(ResourceClass, '/path') (+ redash's
  add_org_resource) now extracts a route per path referencing the Resource
  class, whose get/post verb methods resolve as the handlers.
- Tuple methods: @x.route('/p', methods=('POST',)) — the method regex only
  accepted a list [...]; now accepts a tuple (...) too, so POST/DELETE routes
  aren't mislabeled GET.
- Detection: detect() only checked root app.py for the literal Flask(__name__);
  broadened to requirements/pyproject/Pipfile/setup.py + any entrypoint file
  (root or subdir, e.g. conduit/app.py) that imports flask and instantiates
  Flask(...). flask-realworld (subdir app-factory) 0→19; django not falsely
  detected.

Tests: tuple methods, add_resource. Suite green (808).

tuple methods + detection, gorilla/mux confirmed), and the genuinely
hard/low-precision ones (C callback fan-out, metaprogramming finders, reactive
runtimes, Akka, anonymous closures, lazy data-router, C++ pure-virtual) left
documented with rationale. Adds a gorilla/mux subrouter-var HandleFunc test
(confirms the any-receiver handling already covers it).

* docs(benchmarks): A/B with/without codegraph across every language (S/M/L)

37-cell matrix (every flow-relevant language × small/medium/large indexed
repos): a headless agent answers one canonical flow question per repo, with the
codegraph MCP vs without any MCP. Fresh re-index per cell so the with-arm
reflects current resolvers.

Result: 75% fewer file reads with codegraph (40 vs 158 across cells), ~70%
fewer greps, never more reads in any cell. Biggest wins on medium/large
backends (excalidraw 0R vs 9R, spring-halo 0R vs 9R+8 Bash, jellyfin 4R vs 13R+
21 Bash + a spawned sub-agent); tie zone on tiny repos where the flow fits in
1-2 files.

* feat(mcp): self-sufficient codegraph_trace + CODEGRAPH_MCP_TOOLS allowlist

codegraph_trace now returns a complete flow dossier in one call: each hop with its full body inlined (not just the call-site line), plus the destination's own outgoing calls — the last mile agents otherwise explore/Read to get. Validated by A/B (arm I, 6 repos x 2): >= baseline on reads/turns/cost with no wall-clock regression, because one richer trace call displaces the explore+node+Read follow-ups. Sufficiency, not steering: complete context is what stops further investigation.

Also adds CODEGRAPH_MCP_TOOLS, an optional comma-separated allowlist that trims the exposed MCP tool surface (inert when unset); used to run the tool-ablation experiment cleanly, and useful for constraining an agent to a minimal surface.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs(benchmarks): call-sequence + tool-ablation analysis; agent-eval arms harness

Records why codegraph read savings (-75%) under-convert to wall-clock (-16%): the bottleneck is round-trips + the synthesis turn, not reads. Ablation (arms A-I) shows explore is 68% of payload but load-bearing, trace is path-scoped but under-adopted, instruction/description steering cannot match an append-prompt's salience (and regresses), and the shippable win is making the trace output sufficient (arm I). Adds harness: seq-matrix, run-arms/arms-*, parse-arms.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(mcp): line-number codegraph_node + codegraph_trace source output

node's code block and trace's inlined hop/destination bodies now carry cat -n line numbers (reusing numberSourceLines, matching codegraph_explore and Read), so the agent can cite or edit exact lines without re-Reading the file just to get them. Consistency across the code-returning tools + edit-workflow sufficiency.

* feat(resolution): Java/Kotlin interface & abstract dispatch synthesis

A call through an injected interface (Spring @Autowired svc.list()) or an abstract base dead-ended at the interface method — no static edge to the implementation — so request->service->impl flows broke at the DI boundary. Adds interfaceOverrideEdges: for each class implementing an interface (or extending an abstract base), synthesize interface/base-method -> same-name override 'calls' edges (JVM-gated, capped per class, overload-aware), with an 'interface-impl' trace label. trace + callees now follow the flow into the implementation.

Validated on spring-mall: 310 synth edges, node count unchanged (edges only); trace(PmsProductController.getList, PmsProductServiceImpl.list) connects in 3 hops (controller -> service interface -> impl) where it previously dead-ended at the interface.

* feat(mcp): codegraph_explore surfaces the execution flow from its named symbols

Agents call explore far more than trace and pass a bag of symbol names that spans the flow they're after. explore now resolves those names and surfaces the longest call path AMONG them — riding synthesized dynamic-dispatch edges (callback/react-render/jsx/interface-impl) — leading the output with it, so a flow question answered via explore gets the trace-quality path without switching tools.

Precision: ambiguous tokens disambiguated by CO-NAMING (keep candidates whose qualifiedName SEGMENT matches another named token, so 'list' resolves to PmsProductServiceImpl::list not OmsOrderService::list); BFS anchored at named symbols on both ends with <=1 consecutive unnamed bridge (crosses a missing intermediate, never wanders a god-function's fan-out). Validated by probe: spring-mall getList->service-interface->impl (3 hops); excalidraw mutateElement->triggerUpdate->[callback]->triggerRender->[react-render]->render->[jsx]->StaticCanvas (full re-render chain). No flow section on fuzzy queries (safe). Suite green.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(mcp): explore-flow resolves qualified Class.method query tokens

The agent often passes fully-qualified names to explore (PostEndpoint.publishPost, PmsProductServiceImpl.list) — its most precise input. The tokenizer's file-extension strip mangled Class.method into Class (treating .method as an extension), then the identifier filter dropped anything with a dot, throwing the method away. Now strips only REAL file extensions and keeps qualified tokens, which findAllSymbols resolves exactly; disambiguates ambiguous SIMPLE names by whether their container class is also named (segment match). Validated: 'PmsProductController.getList PmsProductServiceImpl.list' now surfaces getList->interface->impl. (spring-halo's publish flow stays absent — it's reactive/reconciler dispatch with no static edges, a coverage frontier, not an explore-flow gap.)

* docs(claude): record the 'adapt the tool to the agent' retrieval principle

The lever that decides whether a retrieval change lands: make a tool the agent already calls do more with the input it already gives; changes that need the agent to behave differently (different tool, query, examples) hit codegraph's low-salience channels and don't land. Captures the validated evidence (sufficiency + explore-flow pass; steering + new-tools + context-fuzzy-flow fail) and points coverage as the remaining lever.

Fresh with-vs-without A/B on excalidraw (current build, n=3): 3x faster (49s vs 145s), 15x fewer tool calls, ~0 vs 23 reads, and -40% cost ($0.41 vs $0.68). Cost is neutral-to-lower, not flat — compact codegraph answers cache across turns while the without-arm's read/grep thrash is fresh, poorly-cacheable input. Recorded in call-sequence-analysis.md; corrected the CLAUDE.md optimization-target note (still: don't optimize for cost; target wall-clock + tool-call count).

* docs(benchmarks): current-build A/B on all 7 README repos + fix token-measurement bug

Re-ran the README benchmark on the current build (7 repos reindexed, median of 4): avg 35% cost / 57% tokens / 46% time / 71% tool calls saved — reproduces the published README (35/59/49/70), no regression. Adds bench-readme.sh + parse-bench-readme.mjs harness.

Fixes a token-measurement bug: result.usage is last-turn-only in current Claude Code; must sum per-turn assistant usage for cumulative tokens. Corrects the earlier excalidraw note (its '-34% tokens' was off this bug; real ~90%) and the cost MECHANISM (volume/fewer-turns, not cache-ability — the without-arm's huge token volume is mostly cheap cache-reads, so token savings 57% > cost savings 35%). Cost/time were always correct.

Docs · Languages · GitHub · star pill, in that order. Added via the
SocialIcons slot (no full header rebuild, so search/theme/mobile keep
working); the text links and star pill are hidden on mobile, where the
sidebar already covers navigation.

Starlight right-aligns the content against the TOC (margin-inline: auto 0)
on pages with both a sidebar and a TOC, dumping all the empty space on the
left edge — very lopsided on wide monitors. Center the content in its pane.

Lay out each landing feature as icon | divider | text — a 64px icon on the
left, a full-height vertical rule, then heading + description — instead of a
small icon stacked on top. Pure CSS grid (divider via ::before), with
smaller icon/gaps on mobile so the text stays readable.
