2bdc169ce4 fix(extraction): skip submodule worktrees instead of indexing them as duplicates (#945) (#947)
A worktree of a submodule points its `.git` into
`.git/modules/<module>/worktrees/<name>`, but `classifyGitDir` only matched
the top-level `.git/worktrees/` shape — so submodule worktrees fell through
to "embedded" and every symbol they shared with the real submodule checkout
got indexed twice (one report: ~28% of the index was duplicates, inflating
both query results and the DB). Broaden the worktree detector to allow the
optional `modules/<module>` segment. The submodule's own checkout
(`.git/modules/<module>`, no `worktrees/`) is unaffected and stays indexed as
distinct code.

03666584ed fix(extraction): drop the ./ self-entry from git ls-files --directory (#936) (#941)
When the indexed root is a directory an enclosing git repo ignores,
`git ls-files --directory` collapses the whole cwd to a single literal
`./` entry. That sentinel reached the `ignore` matcher, which rejects it
("path should be a `path.relative()`d string, but got "./""), aborting
buildScopeIgnore — the one ignore-building call in FileWatcher.start().
So the MCP daemon's startWatching() threw, was caught as "Failed to open
project", and auto-sync never started: the index silently went stale
until a manual `codegraph sync` (CODEGRAPH_NO_DAEMON=1 was the only
workaround).

Filter the `./`/`.` self-entry wherever we consume `--directory` output
(listIgnoredDirs + the untracked-dir loop in discoverEmbeddedRepoRoots).
Semantically correct, not just a crash guard: `./` means "the whole cwd",
never a nested repo to recurse into.

Not platform-specific (reported on Codex/Windows, reproduced on macOS):
the trigger is git state, not the OS.

JoshandGitHub 6110df8b76 fix(sync): preserve cross-file caller edges across callee re-index (#899) (#927)
`storeExtractionResult` deletes a re-indexed file's nodes via `deleteFile`,
which cascades through `edges.FK ... ON DELETE CASCADE` to delete every edge
whose source OR target is one of those nodes. Edges whose source is in the
re-indexed file are re-emitted by the extractor, but edges whose source is in
a *different* (unchanged) file are not — they are silently dropped. This is
issue #899: re-indexing a callee file severs `calls`/`references` edges from
callers that import it via module-attribute access (`pkg.mod.fn(...)`), so
`codegraph callers fn` reports 0 callers for functions that have real call
sites. A docstring-only edit on the callee is sufficient to trigger it.

The bug affects every incremental path that routes through `sync()` /
`indexFile()`: `codegraph sync`, the file-watcher auto-sync (which calls
`sync()`), and the git sync hooks. `codegraph index` was already fixed by
#894 (it now clears-then-rebuilds, so it's a full re-extraction, not
incremental). `sync` remains the fast incremental path and still has the bug.

Fix: before the delete, snapshot incoming cross-file edges paired with the
target node's (name, kind). After re-inserting the file's nodes + same-file
edges, re-insert the snapshot — re-resolving each edge's target to the
re-indexed node's NEW id by (filePath, kind, name). Node ids are
`sha256(filePath:kind:name:line)`, so any line shift in the callee file (e.g.
a docstring-only edit above the symbol) changes every target id and a naive
re-insert by old id would drop them all. Matching by (kind, name) is stable
across line shifts; if the symbol was renamed/removed, no match is found and
the edge stays dropped (correct). `insertEdges` still filters to endpoints
that exist, so edges whose caller (source) was deleted are also dropped.

Regression tests in `__tests__/sync.test.ts` model the RAGFlow production
case: a `pkg/mod.py` with two callees, both called from `test/test_callers.py`
via `mod.<fn>(...)`. The first test confirms a docstring-only edit that shifts
the second callee's line preserves both incoming edges. The second test
confirms renaming a callee correctly drops its old incoming edge (no phantom
preservation against a non-existent symbol).

Colby McHenryandClaude Opus 4.8 64426cad93 fix(react): recognize forwardRef/memo/styled components + index JSX-file routes (#841)
forwardRef/memo/styled-wrapped component consts were classified as plain
`constant` nodes (the initializer is a call/tagged-template, not a bare arrow),
so the JSX-render synthesizer and component resolution skipped them — callers
and impact returned empty for the entire shadcn/ui-style UI layer. Recognize
them in the tree-sitter extractor as `component` nodes (correct body range +
callee capture), PascalCase-gated so a memoization util stays a constant.

Separately, the `react` resolver's `languages` lacked 'tsx'/'jsx', so its
`extract()` never ran on JSX files — React Router `<Route>`/createBrowserRouter
and Next.js page routes (which only live in .tsx/.jsx) were never indexed. Add
'tsx'/'jsx' and make `extract()` route-only: the component/hook regex it carried
duplicated tree-sitter nodes (a `useAuth` became two `function` nodes) and is
fully superseded by the extractor now.

Validated before/after: taxonomy 0->99 component nodes (35 w/ callers) + 1->15
routes; radix 0->262 components (80 w/ callers); cypress-realworld-app 45->52
routes (7 <Route> tags from .tsx); non-React control unchanged; node count
stable. New tests: react-hoc-component.test.ts + a route e2e in
frameworks-integration.test.ts.

Root-caused by @maxmilian (#846); reported by @Arlandaren.

Colby McHenryandClaude Opus 4.8 80a1044d3d feat(resolution): bridge Vuex string dispatch/commit to actions and mutations
Completes the Vue store dispatch family (the Pinia bridge was 8ea3205). Vuex
dispatches by a runtime STRING key — `dispatch('user/login')` /
`commit('SET_TOKEN')` / `this.$store.dispatch('app/toggleDevice')` — with no
static edge to the handler.

vuexDispatchEdges (callback-synthesizer.ts): the last `/` segment of the key is
the action/mutation name, the preceding segment is the namespace (≈ the module
file). Resolve the name to a function node IN A STORE FILE — the ≥2-signal
store-file gate excludes a same-named `api/` helper (`getInfo`/`login` collide in
practice) — disambiguated by the immediate namespace segment appearing in the
path (handles deep nesting like `d2admin/user/set`), or the same file for a root
local `commit('M')` inside an action. The .vue component is a dispatcher fallback
for top-level setup calls. Surfaces in explore as `dynamic: vuex dispatch`.

Also extracts the canonical Vuex MODULE shape `export default { namespaced,
actions: {…}, mutations: {…} }` (tree-sitter.ts: extractStoreCollectionMethods
off the export_statement, store-file gated) — its object-literal methods were
otherwise never nodes, so d2-admin's actions couldn't be bridged.

Validated 100% precision on three repos — vue-element-admin (55 edges),
vue-admin-template (12), d2-admin (63): 0 non-store targets, 0 namespace
mismatches (54/54 namespaced edges route to the correct module despite 6
colliding `load` actions in d2-admin), 0 on Redux controls (basetool/uwave —
non-string `dispatch()` correctly ignored). Suite green (1613); new
__tests__/vuex-dispatch-synthesizer.test.ts.

Colby McHenryandClaude Opus 4.8 cc9c2f7420 feat(extraction): index Vuex/Pinia store actions, mutations, and getters
A Vue store's callable surface — Vuex `actions`/`mutations`/`getters` and Pinia
store actions — lived only as object-literal properties, so the symbols an agent
looks for (`login`, `getSessionList`, `getAuthMenuList`) were never nodes:
`codegraph search`/`codegraph_node` returned "not found" and the agent had to
read the store by hand. This extracts them as function nodes (with their real
bodies + callees), the foundation under any later dispatch-bridge synthesis.

A corpus probe (vue-element-admin, vue2-elm, Geeker-Admin, MallChatWeb) showed
Vue store dispatch is NOT one clean string-keyed shape but ~5; extraction here
covers the three dominant definition forms:
  - Vuex MODULE: non-exported `const actions/mutations = {…}` collections
    (gated by a ≥2-signal looksLikeVueStoreFile + the object-of-functions shape,
    so a Redux file's stray `const actions` is a 0-node no-op).
  - Pinia OPTIONS: `defineStore({ actions: {…}, getters: {…} })` — methods of
    the actions/mutations/getters properties of a store-factory config.
  - Pinia SETUP: `defineStore('id', () => { const foo = …; return {…} })` — the
    body-local function consts (findPiniaSetupFn + extractPiniaSetupBody; the
    generic body walk doesn't reach nested function scopes). Distinguished from
    an inline action map via objectHasInlineFunctions so zustand/SvelteKit
    extraction is unchanged.

Validated findable on element-admin (50 fns), Geeker (21), MallChat (68);
0-node no-op on a non-Vue control (uwave-web, unchanged at 4496 nodes). Deferred
(documented in the backlog): vue2-elm's `export default {…}` split-file +
computed-key `commit(CONST)` form (n=1), and the dispatch BRIDGE synthesis
(Vuex string-key + Pinia useStore().action()). Suite green (1610); new
__tests__/vue-store-extraction.test.ts.

Colby McHenryandClaude Opus 4.8 e9f7422223 feat(resolution): synthesize RTK Query hook→endpoint dispatch edges
Adds the RTK Query member of the dispatch-through-indirection family
(synthesizedBy:'rtk-query'). An RTK Query endpoint defined inside
`createApi({ endpoints })` and the `useGetXQuery`/`useUpdateYMutation` hook it
generates were both invisible to static extraction, so a `component →
useGetXQuery → getX → queryFn` flow had nothing to connect and explore
dead-ended on the API slice.

Extraction (tree-sitter.ts): mint a function node per endpoint — named by its
key, spanning the queryFn/query handler so its calls attribute — handling both
the `endpoints: build => ({...})` arrow and `endpoints(builder){ return {...} }`
method forms, with a bare-node fallback for factory handlers
(`queryFn: makeFn(url)`); and a function node per generated-hook binding from
`export const {...} = api`, carrying a sentinel signature.

Resolution (callback-synthesizer.ts): rtkQueryEdges bridges each generated-hook
node to its same-file endpoint by the naming convention (strip use + optional
Lazy + Query|Mutation, lowercase head). Component→hook is normal import/call
resolution; the hook→endpoint hop surfaces in explore as `dynamic: rtk query`.

Validated 100% precision (hooks == synth edges, 0 cross-file) on basetool (54),
minusx-metabase (11), shapeshift (13); 0 on the uwave-web control (no createApi
→ a complete no-op). The sentinel gate correctly ignores hand-written
look-alikes (shapeshift's useFoxyQuery is a real custom hook, never bridged).
Full suite green (1608); new __tests__/rtk-query-synthesizer.test.ts.

Colby MchenryandGitHub f34f606342 feat(extraction): same-file value-reference edges for impact analysis — 15 languages (#897)
Adds same-file value-reference edges (reader symbol → const/var it reads) so impact analysis catches a constant's same-file consumers, closing the 'change this table, break its readers' hole. 15 languages validated S/M/L on public OSS: TS/JS/tsx, Go, Python, Rust, Ruby, C, Java, C#, PHP, Scala, Kotlin, Swift, Dart, Pascal/Delphi (+ Svelte/Vue/Astro inherited). Edges-only — node count identical on/off; default ON, CODEGRAPH_VALUE_REFS=0 opts out.

2f6316500d feat(extraction): enable same-file value-reference edges by default (TS/JS) (#895)
Value-reference edges (same-file `references` edges from a reader to the
file-scope const/var it reads) shipped behind CODEGRAPH_VALUE_REFS pending an
agent A/B. The A/B is in: on excalidraw the edges are correct and precise (node
count unchanged) and they transform the impact/blast-radius API — `impact` on a
const consumed by 103 readers goes from 1 affected symbol to the full radius.
That blast-radius API is what `codegraph impact` and CodeGraph Pro's verdict
engine consume, so the win is impact correctness; the agent path showed no
regression. Flip the default on; CODEGRAPH_VALUE_REFS=0 disables.

Also close the one precision gap the A/B surfaced: a bundled/Emscripten
`const Module` re-declared as an inner `var Module` / param produced false
positives (nested readers resolve to the inner binding). isGeneratedFile() is
path-only and can't catch content-minified bundles, so prune SHADOWED targets at
the syntax level — drop any value-ref target whose name is bound by more than one
`variable_declarator` in the file. On excalidraw this removes the 23 false
positives while preserving every real reader (impact unchanged at 170).

Adds regression coverage (there was none): same-file readers are edged, they
surface in the impact radius, shadowed consts are NOT edged, and
CODEGRAPH_VALUE_REFS=0 emits nothing.

5cc155ddc4 fix(index): skip nested git worktrees instead of indexing them as duplicate repos (#848) (#868)
A git worktree nested in a project (e.g. Claude Code's gitignored
`.claude/worktrees/<name>/`) was swept into the index as an embedded repo: its
`.git` is a FILE pointing into the host repo's `.git/worktrees/`, and embedded-
repo discovery treated any `.git` (file or directory) as a distinct repo to
index. Each worktree then duplicated the entire graph — one report went from
~1,850 files to 24,533, with search/explore flooded by stale copies.

classifyGitDir() now distinguishes:
- `.git` directory       -> embedded clone, index (#193/#514/#622, unchanged)
- `.git` file → worktrees/ -> worktree, skip (#848)
- `.git` file → modules/   -> submodule, index (unchanged)

Applied at both embedded-repo entry points: findNestedGitRepos discovery (which
also covers the sync/change-detection path) and the untracked-subdir recursion
in collectGitFiles.

Verified: the reproduction drops from 6 files / betaHelper×3 to 3 files / ×1,
with a genuine embedded clone and submodules still indexed. Regression test added.

06a410e9b4 feat(extraction): R language support (#828) (#839)
R has no declaration syntax — everything is an expression — so the
extractor works through the visitNode hook: functions in every
assignment form (incl. nested, attributed to their enclosing scope),
top-level variables/constants, library()/require() imports and
source() file references (claimed, Lua-style), S4/RefClass/R6/ggproto
classes with their methods and extends edges, setGeneric/setMethod.
Grammar vendored from r-lib/tree-sitter-r v1.2.0 (ABI 14; npm package
is a security placeholder, tree-sitter-wasms has no R).

Benchmarked on AnomalyDetection (8/8 named defs), dplyr (1027 fns),
ggplot2 (150 ggproto classes / 597 methods / 128 extends edges —
adding ggproto mid-bench flipped the large-repo A/B from a regression
to 2.4x faster than the no-codegraph arm).

2c7bbd5387 fix(extraction): C# record-struct kind fidelity + bodiless positional records (#831 follow-up) (#838)
The shipped grammar parses every record form as record_declaration (no
record_struct_declaration node), so 'record struct' mis-kinded as class.
classifyClassNode now distinguishes the value-type form by its struct
keyword child, and extractStruct accepts bodiless positional records
(the no-body gate is for C/C++ forward declarations) instead of
crashing mid-file on them.

ed117ef90b feat(index): multi-repo workspaces index as a whole (#514) (#837)
A workspace holding several independent git repos failed two ways:

- Enumeration: a super-repo whose .gitignore hides its child repos
  (/packages/) indexed 0 of their files — git never lists ignored dirs,
  and the #193 embedded-repo recursion only fired for UNTRACKED dirs.
  Gitignored embedded repos are now discovered (ignored-dirs listing +
  bounded .git search) and enumerated by their own git ls-files.
- Change detection: git status in the parent says nothing about embedded
  repos (untracked OR ignored), so codegraph sync missed every child
  change. Status now recurses per embedded repo.

ScopeIgnore is the new single source of truth for indexer + watcher
scope: parent rules for ordinary paths, the child repo's own rules for
paths inside it, built-in defaults uniformly on full paths (a git repo
inside node_modules is an npm git-dependency, not project code), and
ancestors of embedded roots are never pruned (the Linux per-directory
watcher must descend to reach them).

Non-git workspace roots already worked via the per-directory gitignore
walk — locked in by test.

823ffd1c3d feat(extraction+resolution): Astro support — frontmatter/template extraction + src/pages routes (#768) (#815)
.astro files were not indexed at all, leaving a typical Astro site mostly
invisible to search/impact/explore. New AstroExtractor (Svelte/Vue SFC
pattern): component node per file, TS frontmatter + <script> blocks
delegated to the TypeScript extractor, template {fn(...)} calls (incl. the
multiline `{posts.map((post) => (` opening line), PascalCase component-tag
references. New astroResolver: Astro global + astro:* virtual modules as
framework-provided, component resolution with the #764 ambiguity rule,
src/pages/ file-based routes ([param]→:param, [...rest]→*rest, _-prefixed
and *.config.* excluded). SFC languages now preload the TS/JS grammars
their extractors delegate to (a pure-SFC file set previously had none
loaded). Also fixes a pre-existing Svelte/Vue script-block off-by-one that
reported every script symbol one line low.

Validated per the playbook: stalux (the issue's repro) 54/54 .astro files
indexed, getIconNode found at its exact line, 14/14 routes, 93.0% fair
cross-file coverage; AstroPaper 27/27 components, 13/13 routes (underscore
dirs correctly excluded), explore connects page→Card→Datetime through the
jsx-render synthesizer; node/edge counts stable across re-syncs.

222af6b87c fix(mcp+resolution): stop conflating same-named symbols across monorepo apps (#764) (#813)
A NestJS-style monorepo has one UserService/UserModule/UserRepository per
app; with no package concept for TS they share one global name scope and
agents visibly warned that CodeGraph was mixing unrelated classes.

Two distinct problems, two fixes:

1. TOOL AGGREGATION. callers/callees returned one merged list across every
   same-named match, and impact merged all their blast radii into a single
   overstated subgraph. Now: matches group into DISTINCT DEFINITIONS
   (filePath + qualifiedName — same-file overloads still merge, that's the
   overload feature) and render one file-labeled section per definition;
   a new `file` argument (path or suffix, like codegraph_node's) narrows
   to one definition, suppressing the stale aggregation note; a
   non-matching `file` falls back to all definitions with a note.
   server-instructions documents the behavior.

2. RESOLUTION WRONG EDGES. Auditing a real monorepo (amplication, 54k
   nodes) found 1,036 cross-package `references` edges into duplicated
   names. Root cause: the React framework resolver ran PascalCase
   component resolution on refs from PLAIN .ts FILES (a GraphQL types
   file's own `Account` type alias lost to an arbitrary same-named CLASS
   in another package — the resolver's blind `components[0]` fallback at
   confidence 0.8 outranked the name-matcher's proximity-correct 0.7).
   Component resolution is now gated to JSX-capable refs (tsx/jsx) and
   never guesses among multiple candidates without a positional signal
   (same-dir / component-dir / unique). Cross-package wrong edges:
   1,036 -> 40 (-96%; the remainder are genuine shared-model imports and
   codegen template scaffolds), with the freed refs re-resolving to the
   correct same-file/same-package targets. excalidraw (a real React repo)
   is a zero-delta control — legitimate component refs all carry
   same-dir/component-dir signals.

Graph-level separation was verified correct on a fixture before any
changes (import + proximity resolution keeps apps apart) — the conflation
was tool-level plus the react-resolver edge class.

Tests: 6-test e2e suite (grouped callers/callees, per-definition impact
radii, file narrowing, fallback note, cross-app edge isolation) + react
resolver unit tests updated to production reality (tsx refs resolve,
plain-ts refs decline). Full suite 1398 passed. EXTRACTION_VERSION
23 -> 24 (re-index to drop the wrong cross-package edges).

Closes #764

dce61a5f4a fix(extraction): qualified Type::member refs skip the name gate — no-import references resolve (#812)
`KtHandlers::handle` registered from another file produced no edge: the
extraction gate required the scope to be a same-file type or an IMPORTED
name, but Java/Kotlin same-package references and Kotlin companion members
need no import at all, so the gate could never see them. (The "companion
members extract unqualified" limit recorded during Arc A was a probe
artifact: a SINGLE-LINE `class X { companion object { … } }` is an
upstream tree-sitter-kotlin misparse (ERROR node); real multi-line
companions extract transparently as qualified methods of the class.)

Qualified `Type::member` candidates now skip the name gate the same way
`this.<member>` ones do: the explicit-ref syntax is self-selecting, and
resolution stays scope-suffix-anchored + unique-or-drop, so a
`Decoy::handle` can never match a `KtHandlers::handle` ref (tested).

A/B vs main: rxjava +4 (same-package `Maybe::just` / `Single::just`
method refs), fmt +3 (gtest `&Test::DeleteSelf_` /
`&TestSuite::RunSetUpTestSuite` cross-file member pointers), okio 0-delta,
redis byte-identical — every new edge verified genuine, zero calls edges
touched, node counts identical.

Full suite 1392 passed. EXTRACTION_VERSION 22 → 23 (re-index to benefit).

1f15f93feb feat(extraction): PHP string/array callables + Ruby lifecycle-hook symbols (#811)
The last two deferred callback-registration shapes from #756, each scoped
to positions where the reference is trustworthy:

PHP — a string is a callable ONLY in a known callable position:
  - string args of core HOFs (usort, array_map, array_filter,
    call_user_func*, preg_replace_callback, spl_autoload_register,
    set_error_handler, … — PHP_CALLABLE_HOFS): ungated (PHP globals are
    referenced cross-file without imports) + resolution unique-or-drop,
    function-kind only ('Cls::m' strings resolve qualified)
  - array callables anywhere in call args: [$this, 'method'] routes through
    the class-scoped this. resolver (parents included); [Foo::class,
    'method'] resolves qualified
  - strings to arbitrary functions: deliberately nothing

Ruby — hook-DSL symbols name a method of the enclosing class:
  (skip_)?(before|after|around)_* / validate / set_callback /
  helper_method / rescue_from(with:) symbols → class-scoped this.<sym>,
  riding the supertype pass so `before_action :authenticate` in a
  controller resolves to ApplicationController's method. `validates`
  (plural) excluded — its symbols name ATTRIBUTES. Class-body-level hooks
  attribute to the CLASS node (the scoped resolvers now accept class-like
  from-nodes).

Also hardened while validating: the this.X supertype pass is now
NODE-anchored — file-anchored class node → implements/extends edge targets
→ contains-anchored member lookup — replacing the name-keyed
getSupertypes walk, which unioned every same-named class's parents (rails
has a dozen `Engine`s) and produced a cross-class wrong edge.

A/B vs main: WordPress +556 (14/14 sampled genuine — [$this,'m'] wiring,
array_map('absint',…), sodium polyfill call_user_func_array dispatch);
rails/rails +385 after the node-anchored fix (16/16 sampled genuine, incl.
inherited hooks across real extends edges); controls byte-stable
(excalidraw 0-delta, redis identical, typeorm keeps its +4 inherited
getters). The only calls-edge deltas anywhere are pre-existing
minified-bundle resolution jitter (wp-tinymce.js single-letter symbols).

Full suite 1391 passed. EXTRACTION_VERSION 21 → 22 (re-index to benefit).

38095aa95b feat(resolution): inherited this.X, Java/Kotlin cross-file method refs, Swift type scoping (#810)
Three callback-registration shapes deferred from #756/#808, one arc:

1. INHERITED this.X (TS/JS + every this.-routed language): a `this.<member>`
   registration whose member isn't on the enclosing class defers to a second
   pass (resolveDeferredThisMemberRefs — in-memory like deferredChainRefs,
   runs after implements/extends edges persist, same lifecycle as the #750
   conformance pass) and resolves up the supertype chain, depth-capped BFS,
   validated targets only. `bus.on("submit", this.handleSubmit)` in a
   subclass links to FormBase::handleSubmit; same-named methods on unrelated
   classes never match. this.-prefixed candidates skip the extraction name
   gate (an inherited member can't be in definedHere).

2. JAVA/KOTLIN qualified method refs: `Handlers::onMessage` /
   `OtherClass::handle` emit QUALIFIED names resolved by the scoped
   suffix-matcher — cross-file capable, gated on the scope name being a
   same-file type or an imported name (dotted JVM imports now contribute
   their last segment). `this::m` and `super::m` route through the
   class-scoped resolver (super rides the supertype pass). References
   through a VARIABLE (`subscriber::onNext`) deliberately produce nothing —
   receiver type is unknowable; RxJava's baseline bare capture was resolving
   these to same-named same-file methods (a test method "registering" an
   anonymous class's onNext) — the rework drops 18 such wrong edges and
   keeps the 7 genuine Type::method refs RxJava's main tree actually has.

3. SWIFT enclosing-type scoping (implicit self): bare callback names match
   methods only of the from-symbol's own type (extension/nested scopes
   reconciled by suffix), and top-level code never matches methods.
   Alamofire: −44 wrong edges (parameters like `request`/`data`/`retrier`
   resolving to same-named methods on unrelated protocols), all verified;
   the same-class param collision (`task`) remains and is documented.

New ResolutionContext.getNodeById lets matchers derive the from-symbol's
class scope. Controls: redis/fmt fnref edges byte-identical; excalidraw
stable; typeorm +4 genuine inherited-getter dependencies; zero calls edges
changed on any of 7 A/B repos; nodes identical everywhere. Kotlin
companion-object members extract unqualified (pre-existing) so
`Type::companionFn` stays silent rather than guessing — documented.

Full suite 1389 passed. EXTRACTION_VERSION 20 → 21 (re-index to benefit).

38eb4e688c fix(extraction): classify TS/JS class fields by value — properties, not methods (#808) (#809)
Every TS `public_field_definition` / JS `field_definition` extracted as a
method-kind node, so a plain field (`public fonts: Fonts;`) was reported
as callable: class shape was misrepresented, kind-based filtering was
defeated, and bare-name call resolution landed on data fields — typeorm's
boolean `ColumnMetadata::isArray` field was soaking up Array.isArray(...)
call edges (685 such wrong edges on typeorm alone).

Classification now follows the VALUE (classifyMethodNode hook, mirroring
resolveBody's callable detection): arrow-function / function-expression
fields and HOF-wrapped ones (`onScroll = throttle(() => {…})`) stay
methods with their bodies walked; everything else becomes a property that
keeps its type-annotation references edge, visibility, static-ness, and
decorators. Field initializers are now walked too (`history =
createHistory()` attributes the call to the property — previously
invisible), and JS class fields — whose name lives in the grammar's
`property` field, so they never extracted a symbol at all — now appear in
the graph (resolveName on the JS extractor).

With fields correctly kinded, `this.X` callback registration is re-enabled
for TS/JS (removed in #807 because field pseudo-methods made it mostly
wrong): `this.<member>` candidates resolve CLASS-SCOPED
(resolveThisMemberFnRef) — the target must be a function/method sharing
the from-symbol's qualified-name class prefix, same file, no fallback —
so `addEventListener("online", this.onOfflineStatusToggle)` and API-object
wiring (`{ mutateElement: this.mutateElement }`) produce registration
edges to the enclosing class's own method, while `this.fonts` (a
property) and inherited/unknown members yield no edge.

A/B (baseline = #807 main): excalidraw / typeorm / express — node counts
identical on all three; kinds shift method→property only (typeorm: exactly
7,406 swapped; excalidraw also corrects 5 anonymous-class mock fields that
were function-kind); every one of the 736 dropped call edges targeted a
node that is now a property (calls into data fields — verified 100%);
gains are retargets to real callables, initializer-call attributions, and
+74/+7 class-scoped this.X registration edges (sampled: addEventListener/
removeEventListener wiring, imperative-API method maps). Full suite green
(1386).

EXTRACTION_VERSION 19 → 20 (re-index to benefit).

8a114ba53c feat(extraction): capture function-as-value — callback registration sites in callers/impact (#756) (#807)
A function name used as a VALUE — passed as an argument
(signal(SIGINT, handler), qsort(..., compare)), assigned to a function
pointer or field (ops->recv_cb = my_cb, OnClick := Handler), or placed in
a struct initializer / handler table ({ .recv_cb = my_cb },
{ "get", getCommand }) — produced no edge in ANY of the 19 tree-sitter
languages, so registered callbacks looked dead and their registration
sites were invisible to callers/impact.

This adds table-driven function-as-value capture across all 19 languages
(plus the wrapper forms: &fn, &Cls::method, Java Class::m, Kotlin ::f,
Swift #selector, ObjC @selector, Ruby method(:sym), Scala eta, Pascal
@Handler), gated at extraction (same-file definitions + imported
bindings; C-family file-scope initializers are constant-expression
contexts and skip the gate, which is how redis-style cross-file command
tables resolve), and resolved by a dedicated strategy: function/method
targets only, same-file first, unique-or-drop cross-file, no fuzzy
fallback ever. Edges persist as kind 'references' with metadata.fnRef,
so getCallers/getImpactRadius surface them with zero graph-layer
changes; MCP callers/callees label them "via callback registration".

Precision rules bought by real-repo false positives (full A/B record in
docs/design/function-ref-capture.md): C++ is &-explicit outside
file-scope tables (fmt's begin/out/size collisions; out-of-line member
defs are function-kind); TS/JS/Python bare ids resolve to functions only
(TS class fields extract as method-kind — pre-existing quirk); Swift
refuses same-file method overload-families; param-forward shapes
(this.x = x, value: value) and destructuring are skipped; minified
bundles (*.min.js) produce no candidates.

Validated on 17 public OSS repos (redis, excalidraw, gin, bytes, okhttp,
okio, Alamofire, flask, sinatra, Newtonsoft.Json, scopt, provider,
busted, Fusion, AFNetworking, PascalCoin, fmt): node counts identical,
zero calls edges lost or gained, references strictly additive
(+3,200 registration edges total), precision spot-checked by reading
sampled source lines (redis 30/30, flask 8/8). Deliberately NOT covered:
indirect-dispatch resolution (o->cb(x) → impl) — that needs data-flow
through struct fields, and a wrong edge is worse than none.

EXTRACTION_VERSION 18 → 19 (re-index to benefit).

Closes #756

0df9246752 fix(extraction): capture & clean docstrings across all README languages (#780) (#806)
* fix(extraction): capture docstrings for export/const/decorator-wrapped symbols (#780)

getPrecedingDocstring walked previousNamedSibling from the EMITTED
declaration node, so it only found a leading comment when the comment was
a direct sibling of that node. For a declaration nested under a wrapper —
`export class X` / `export const f = () => {}` (export_statement /
lexical_declaration), a plain const arrow (variable_declarator), or a
decorated Python def/class (decorated_definition) — the comment is a
sibling of the WRAPPER, so the inner node had no preceding comment and
the docstring was stored as NULL.

Climb out through the wrapper node(s) before scanning for the comment.
Each wrapper holds exactly one declaration, so this can't mis-attribute a
comment to a sibling (verified: an uncommented method does NOT inherit its
class's comment). Also strip leading `#` from Python/Ruby/shell line
comments, which the cleanup chain missed (Python docstrings used to keep
their `#`).

Query/extraction-layer change to a parse helper; re-index to pick up
docstrings on already-indexed files. Verified on the reporter's JS/TS and
Python repros (8/8 now captured) plus over-walk controls; +3 tests.

* fix(extraction): clean comment markers across all supported languages (#780)

Validating docstring capture across every README language surfaced that
the marker cleanup only knew C-style `//` and `/* */`, plus the `#` added
earlier this branch. Doc comments in other styles were captured but left
their markers in the stored text:

  - Rust/Swift/Kotlin doc lines `///` and `//!`  -> leading `/` / `!` leaked
  - Lua/Luau `--` and `--[[ ]]`                  -> not stripped
  - Pascal `{ }` and `(* *)`                     -> not stripped

Extract the cleanup into cleanCommentMarkers() and handle every style.
Paired block delimiters are stripped only when the comment OPENS with one,
so a line comment that happens to end with `}` / `*)` / `]]` is never
truncated; per-line markers stay anchored at line start.

Validated end-to-end (extract -> index -> codegraph_node output) across
all 19 tree-sitter code languages plus Svelte/Vue `<script>` blocks: every
one now stores and returns a clean docstring. +1 cross-language test.

dac00e7d44 fix(pascal): attribute a free routine's calls to it, not the file (#795)
A Pascal/Delphi procedure or function defined ONLY in the implementation section
(no interface declaration, not a class method) had no node of its own, so
extractPascalDefProc's caller lookup fell through to the nodeStack top — the file
node. Every call in such a routine's body was lumped under the unit: callers
returned the file, and impact couldn't attribute the call to the routine. (Methods
were fine — they get a node from their class declaration.)

Fix: when extractPascalDefProc finds no existing node for a FREE routine (a name
with no `.`), create a function node for it and attribute the body's calls to it.
Interface-declared free routines already have a node (found via the methodIndex),
so there's no duplicate; methods keep their existing class-declaration node.

PascalCoin A/B: +511 / -145 — the +511 are calls now correctly attributed to their
actual routine (`allocate_new_datablock -> TDisposables::GetMem`), replacing -145
file-level aggregates; +248 new function nodes for the implementation-only
routines. New synthetic test asserts a free routine's call attributes to it
alongside a method caller. EXTRACTION_VERSION 17->18. Full suite green.

35dce04e1f feat(pascal): extract paren-less method calls (Obj.Free; / TFoo.GetInstance.DoIt;) (#793)
Pascal/Delphi lets a no-arg method or procedure drop its parens, so the call
parses as a bare `exprDot` (not an `exprCall`) and was never recorded as a call —
callers/impact/trace missed all of them (e.g. `Obj.Free`, `List.Clear`, the
paren-less factory chain `TFoo.GetInstance.DoIt`).

extractPascalParenlessCall handles these, wired into visitPascalBlock scoped to
STATEMENT position only: a bare `Obj.Field;` statement is a no-op, so a
statement-level dot expression is a call — but a dot in assignment LHS/RHS or a
condition is left alone, since there it's genuinely ambiguous with a
field/property access. The chained paren-less form reuses the #750 chain encoding
(gated on the Delphi `TFoo`/`IFoo` type convention) and resolves the same way.

PascalCoin A/B: +1131 / -1 — purely additive, and all 1131 new edges resolve to
METHOD nodes (zero field/property false positives, confirming the statement-level
gate). 3 new synthetic tests (paren-less call, paren-less chained factory, and the
property-write/read non-extraction guard). EXTRACTION_VERSION 16->17. Full suite green.

af56f3539d fix(pascal): resolve chained factory calls TFoo.GetInstance().DoIt() (#750) (#791)
Ports the #645/#608 chained-receiver mechanism to Pascal/Delphi — which I'd
previously mis-scoped as blocked. The paren'd chained form extracts fine; it just
hit the chained-call gap like the others (with a decoy, `TFoo.GetInstance().DoIt()`
mis-resolved to a same-named method on an unrelated class).

- pascal.ts: getReturnType reads the method's `typeref` (a `function GetInstance:
  TBar` returns TBar; an interface return `IFoo` is captured too).
- tree-sitter.ts: extractPascalCall now re-encodes a chained call `TFoo.GetInstance().DoIt`
  (the exprDot's receiver is an exprCall) instead of collapsing it to bare `DoIt`.
  Gated on the Delphi type-naming convention (`TFoo`/`IFoo`) so a capitalized
  VARIABLE chain (Pascal capitalizes locals too — `Curve.X().Y()`, `Self.X().Y()`)
  stays bare and keeps its existing bare-name resolution.
- name-matcher.ts: `pascal` joins the dotted-chain gate + CHAIN_LANGUAGES +
  CONSTRUCTS_VIA_BARE_CALL (a `TFoo(x)` typecast yields a TFoo). When the factory's
  return type wasn't captured (a `constructor Create` has no `: TBar` but returns
  its class), resolve the method on the factory class itself. resolveMethodOnType
  validates, so a wrong inference yields no edge.

Validation: 4 synthetic tests (factory+decoy, constructor chain, typecast chain,
absent-method safety). Real-repo A/B on PascalCoin (772 files): +19 / -18 — 15 of
the -18 are correct class→interface retargets (`GetInstance(): IAsn1OctetString`
resolves `.GetOctets` on the declared interface, not baseline's concrete-class
guess); 3 are negligible drops (0.02%). EXTRACTION_VERSION 15->16. Full suite green.

d21d2dfa50 fix(objc): resolve chained message-send calls [[Foo create] doIt] (#750) (#786)
Ports the #645/#608 chained-receiver mechanism to Objective-C. A message send
whose receiver is itself a message send — `[[Foo create] doIt]` — used to drop
the receiver, so `doIt` name-matched a same-named method on an unrelated class
(commonly a test helper's `init` or an Apple-SDK method).

- objc.ts: getReturnType reads the method's `method_type`, SKIPPING nullability /
  ARC qualifiers (`nonnull instancetype` must yield instancetype, not `nonnull`).
- tree-sitter.ts: the message_expression branch now re-encodes a chained send
  `[[Foo create] doIt]` as `Foo.create().doIt` when the inner receiver is a
  capitalized class and the outer selector is unary.
- name-matcher.ts: `objc` joins the dotted-chain gate + CHAIN_LANGUAGES. A
  class-message factory returns an instance of the RECEIVER class by convention
  (`instancetype`), so when the factory's own return type isn't recoverable
  (`alloc`/`new`/`shared…` return instancetype, or aren't user nodes), the
  receiver's type is the class itself — this resolves the ubiquitous
  `[[X alloc] init]` and singleton chains. resolveMethodOnType validates against
  the class and its supertypes, so a wrong inference yields no edge.

Validation: 4 synthetic tests (factory+decoy, superclass conformance, absent-method
safety, the nonnull-instancetype singleton). Real-repo A/B on SDWebImage (208 files):
+35 / -75 — all corrections (the -75 are wrong `init` mis-matches to a test helper /
wrong class, retargeted to the right class's init in the +35, plus 2 Apple-SDK chains
on unindexed classes). db stable, no node explosion. EXTRACTION_VERSION 14->15.

16c73e2b0e fix(dart): resolve chained static-factory / constructor calls Foo.create().bar() (#750) (#762)
Ports the #645/#608 chained-receiver mechanism to Dart, plus makes Dart factory
and named constructors first-class so their chains can resolve at all. A call
whose receiver is itself a call — `Foo.create().bar()` (static factory or
factory/named constructor) — used to drop the receiver to a bare `bar`, which
name-matched a same-named method on an unrelated type (commonly a stdlib
`Option`/`Iterator` `.map`/`.where` mis-tied to the project's own class).

- dart.ts: extractBareCall now re-encodes `Foo.create().bar` when the chain
  starts with a capitalized type; getReturnType captures the return type (generic
  `List<Foo>` → `List`); factory (`factory Foo.create()`) and named (`Foo._()`)
  constructors are indexed as `Foo::create` / `Foo::_` with return type = the
  class (via resolveName + getReturnType + constructor_signature in methodTypes).
- The UNNAMED ctor `Foo()` is deliberately NOT extracted (isMisparsedFunction),
  so plain construction stays an `instantiates` edge to the class rather than a
  call to a phantom `Foo::Foo` method.
- dartCtorInfo validates a "constructor" against the enclosing class name, so a
  method tree-sitter MISPARSES as a constructor — `@override (A, B) m()`, where
  the annotation swallows the record return type and `m()` looks like a one-id
  constructor_signature — is still extracted as the method it is (regression
  found on localsend; covered by a new test).
- name-matcher.ts / index.ts: `dart` joins the dotted-chain gate,
  CONSTRUCTS_VIA_BARE_CALL (case construction), and CHAIN_LANGUAGES (conformance
  for superclass/mixin methods). resolveMethodOnType validates, so a wrong
  inference yields no edge.

Validation: 7 synthetic tests (static factory, factory/named ctor, construction,
conformance, absent-method safety, the misparse regression, instantiation-not-
hijacked). Real-repo A/B on localsend (368 Dart files): hand-written +17/-10 — all
corrections (the -10 = 7 wrong stdlib/extension misattributions removed + 3 ctor
source-renames), plus additive factory/named-ctor call resolution. Instantiation
preserved; no node explosion. EXTRACTION_VERSION 13->14. Full suite green.

2f96f58cbb fix(scala): resolve chained static-factory/apply calls Foo.create().bar() (#750) (#761)
Ports the #645 (C++) / #608 (PHP) chained-receiver mechanism to Scala. A call
whose receiver is itself a call — `Foo.create().bar()` (companion factory),
`Builder(cfg).bar()` (case-class apply), or a fluent chain — used to drop the
receiver to a bare `bar`, which name-matched a same-named method on an unrelated
type. The most common wrong edge was a stdlib `Option`/`Iterator` `.map`/`.flatMap`/
`.foreach` mis-attributed onto the project's own same-named class.

- scala.ts: `getReturnType` reads the `return_type` field — generic `List[Foo]`
  → container `List`, qualified `pkg.Foo` → `Foo`, `this.type` left undefined.
- tree-sitter.ts: re-encode `Foo.create().bar` when the inner call's receiver chain
  starts with a capital (companion factory / case-class apply); instance chains
  (`list.map().filter()`) stay bare.
- name-matcher.ts: `scala` joins the dotted-chain gate + CONSTRUCTS_VIA_BARE_CALL
  (case-class `apply` constructs the class); resolveMethodOnType validates, so a
  non-conventional `apply` returning another type yields no edge, not a wrong one.
- index.ts: `scala` joins CHAIN_LANGUAGES so trait-inherited methods resolve via
  the conformance second pass.

Validation: 4 synthetic tests (factory+decoy, case-class apply, trait conformance,
absent-method safety). Real-repo A/B on gatling (750 Scala files): +14 / -59 unique
edges — all corrections. The +14 are retargets (e.g. `HttpProtocolBuilder(cfg).baseUrl`
now resolves to HttpProtocolBuilder::baseUrl, not the same-named private BaseUrlSupport
helper); the -59 are wrong edges removed (stdlib Option/Iterator monad calls
mis-tied to the project's Validation::*, self-loops, decoy collisions) — zero genuine
factory chains dropped (verified: gatling has no real Validation.success().map() chains).

ccced9e358 fix(go): resolve chained factory-function calls New().Method() (#750) (#760)
* fix(go): resolve chained factory-function calls New().Method() (#750)

A Go call through a chained factory function — `New().Method()`,
`With(cfg).Build()` — dropped the receiver to a bare method name, which then
attached to a same-named method on an unrelated type (a wrong edge) or didn't
resolve. Ports the #645/#608 mechanism for Go's bare-factory receivers:

- Part 1: capture Go return types; a pointer `*Foo` -> `Foo`, a multi-return
  `(*Foo, error)` -> its first result, qualified `pkg.Foo` -> `Foo`.
- Part 2: encode a bare-factory chain (`New().Method`), gated to an `identifier`
  receiver so instance chains (`obj.Method().Other()`) keep bare-name.
- Part 3: matchDottedCallChain bare-inner Go branch looks up the FUNCTION's
  return type, then resolves+validates the method on it. Wired into the
  conformance pass so a method promoted from an embedded struct (`type Widget
  struct{ Base }` -> the existing `extends` edge) resolves. FALLBACK: when the
  inner isn't a resolvable function (a package-level VARIABLE holding a function
  value, e.g. gin's `engine()`), fall back to bare-name so the edge isn't dropped.

Validated: synthetic decoy + args + multi-return + embedded-conformance + absent
safety tests (4/4); full suite green. Real-repo A/B on gin (99 .go): pre-fallback
-40 = 25 wrong self-loops removed (good) + 15 correct `Engine::ServeHTTP` dropped
(gin's ginS variable-factory `engine()`); the fallback recovers the 15. gin A/B
re-confirm with the fallback is PENDING (local index flakiness, not a code issue).
EXTRACTION_VERSION 11 -> 12.

* fix(go): stop the chained-call fallback from looping the batched resolver

The Go variable-inner fallback (for chains like `engine().ServeHTTP()` whose
inner is a package-level var, not a factory function) resolved the method via
a synthetic bare-name ref and propagated THAT ref as `.original`. Its
`referenceName` was the bare `ServeHTTP`, not the stored `engine().ServeHTTP`,
so `resolveAndPersistBatched`'s keyed `deleteSpecificResolvedReferences` no-oped,
the offset-0 batch never drained, and the loop re-resolved + re-inserted the
same rows forever — a runaway that grew a 99-file repo (gin) to 5,050,206 edges
/ 1.4 GB before filling the disk.

- name-matcher.ts: tie the bare-name match back to the original `ref` so the
  batch-cleanup delete matches the stored row and the loop drains.
- index.ts: add a non-progress guard to resolveAndPersistBatched — if the
  unresolved_refs table doesn't shrink after a batch, stop instead of growing
  the graph without bound (defense-in-depth for any future keyed-delete mismatch).
- resolution.test.ts: regression test for the variable-inner chain — asserts the
  fallback edge resolves AND the edge count stays bounded (no explosion).

gin A/B (post-fix): db 5.8 MB / 3,699 calls edges; net-zero unique-edge diff vs
main (the fallback recovers the dropped edges, adds no wrong ones). Full suite green.

5805f01957 fix(rust): resolve chained associated-function calls Foo::new().bar() (#750) (#757)
A Rust call through a chained associated function — `Foo::new().bar()`,
`Foo::with(cfg).build()` — dropped the receiver to a bare method name, which
then attached to a same-named method on an unrelated type (a wrong edge) or
didn't resolve. Ports the #645/#608 mechanism for Rust's `::` receivers:

- Part 1: capture Rust return types; `-> Self` yields the `self` marker (resolved
  to the impl's own type, like PHP), references/generics are unwrapped/reduced.
- Part 2: encode an associated-function chain (`Foo::new().bar`), gated to a
  scoped_identifier receiver so instance chains (`x.foo().bar()`) keep bare-name.
- Part 3: resolve via matchScopedCallChain (PHP's `::` resolver, generalized),
  validated by resolveMethodOnType. Wire Rust into the conformance second pass
  (matchScopedCallChain variant) so a chained method provided by a trait the type
  implements (`impl Trait for Type` → existing implements edges) resolves too.

Validated: synthetic decoy + args + Self + trait-default-conformance + absent
safety tests; full suite green (lone failure is the known-flaky #662 daemon test,
passes in isolation). Real-repo A/B vs main: clap (329 .rs) a net precision win —
**+937 added (96% correct builder methods), 622 wrong->right retargets**
(`Command::new().arg()` was mis-resolving to `ArgGroup::arg`, now `Command::arg`),
+162 net unique edges; the pure-drops are largely wrong bare-name edges the fix
correctly stops emitting. tokio-rs/bytes 0/0 (no regression). Known limit: the
single-hop mechanism re-encodes only the first hop of a chain (deeper hops keep
bare-name) — clap's unusually deep builder chains are partly covered.

7c7f0dd56f fix(swift): resolve chained static-factory/fluent calls + nested-extension naming (#750) (#755)
Completes Swift in the #750 chained-call series (after Java #751, Kotlin #752,
C# #753, conformance #754). Two parts:

1. Swift chained-call resolution (the #645/#608 mechanism): capture Swift return
   types (positional, member types -> last segment), encode capitalized-receiver
   chains `Foo.make().draw()` / `Foo(args).draw()`, resolve+validate via the
   shared matchDottedCallChain (+ constructor branch). Fixes the decoy wrong-edge
   bug where a chained method dropped to a bare name and attached to a same-named
   method on an unrelated class.

2. Nested-type extension naming fix: `extension KF.Builder: KFOptionSetter` parsed
   as a class_declaration named `KF.Builder` (dot) — inconsistent with the type's
   own declaration `KF::Builder` (name `Builder`) — so the extension's conformances
   and members were invisible to a chained call on the type. A Swift resolveName
   now names a nested-type extension by its last segment (`Builder`), so its
   `implements`/`extends` edges and methods are found by the supertype walk
   (conformance #754) and the simple-name method match.

Validated: synthetic decoy + args + constructor + absent-method tests; full suite
green; nested-extension repro (`KF.url().onSuccess()` resolves via conformance to
the protocol method). Real-repo A/B vs main (conformance) — Alamofire and
Kingfisher both **0 added / 0 removed, node count unchanged**: NEUTRAL and SAFE.
The prior -168 Kingfisher regression (from the naming inconsistency) is eliminated;
Swift's unique-named fluent methods already resolved by bare name, so the chain
path lands the same edges — the value here is decoy-collision correctness, the
nested-extension naming fix, and consistency with the other four languages.

48d4654e8d feat(resolution): conformance-aware chained-method resolution (#750) (#754)
* feat(resolution): conformance-aware chained-method resolution (#750)

A chained static-factory/fluent call whose method lives on a SUPERTYPE the
receiver conforms to — a protocol-extension method (Swift), an interface default
method, or an inherited superclass method — now resolves. resolveMethodOnType
falls back to walking the return type's implements/extends edges (via the new
context.getSupertypes) when the method isn't a direct member. Because those edges
don't exist during the single-pass resolution, a second pass
(resolveChainedCallsViaConformance) re-resolves the deferred chained refs after
edges are built. Still validated, so a wrong inference yields no edge.

aa07dc59d4 fix(csharp): resolve chained static-factory calls Foo.Create().Bar() (#750) (#753)
A C# method called through a static factory or fluent chain —
`Foo.Create().Bar()`, `JObject.Parse(s).Property(...)`,
`Instant.FromUtc(...).InZone(zone)` — lost the receiver's type, so the chained
method didn't resolve and the call was invisible to callers/impact/trace. Ports
the #645/#608 mechanism to C# (additive, like Java #751):

- Part 1: capture C# return types in the extractor, reading the `returns` field
  (`static Foo Create()` -> `Foo`); predefined/array/generic/nullable/namespaced
  types are normalized or skipped.
- Part 2: encode a chained `member_access_expression` receiver
  (`Foo.Create(args).Bar()`) as `inner().Bar` with normalized empty parens, so
  factory calls that take arguments still split. Non-chained member calls keep
  their existing `recv.Method` text.
- Part 3: resolve via the shared matchDottedCallChain (now Java/Kotlin/C#),
  validated by resolveMethodOnType so a wrong inference yields NO edge.

Known limitation (safe): C# extension-method chains don't resolve, since the
method lives on the extension class, not the receiver's type — no edge, never a
wrong one.

Validated: synthetic decoy + args + absent-method safety tests; full suite green;
real-repo A/B on Newtonsoft.Json (945 .cs: +3, 0 lost) and nodatime (488 .cs:
+73, 0 lost) — node count identical (no explosion), 0 edges lost, precision
spot-checked verbatim (Instant.FromUtc().InZone(), Offset.FromHoursAndMinutes().Plus(),
OffsetDateTimePattern.CreateWithInvariantCulture().WithTwoDigitYearMax()).
EXTRACTION_VERSION 7 -> 8.

3e04650850 fix(kotlin): resolve chained companion-factory calls Foo.getInstance().bar() (#750) (#752)
A Kotlin method called through a companion-object factory, fluent chain, or
constructor — `Foo.getInstance().bar()`, `Config.create(opts).build()`,
`STMTransaction(f).commit()` — dropped the receiver to a BARE method name, which
then name-matched a same-named method on an unrelated class (a wrong edge) or
failed to resolve. Ports the #645/#608 mechanism to Kotlin:

- Part 1: capture Kotlin return types in the extractor. tree-sitter-kotlin
  exposes no field names, so the return type is read positionally (the type node
  after function_value_parameters); inferred/Unit/Nothing returns yield none.
- Part 2: encode a CLASS/companion-factory call-receiver chain as `inner().method`.
  Gated to a capitalized receiver (`Foo.getInstance()` / `Foo(args)`) so instance
  chains (`list.filter{}.map{}`) keep their bare-name behavior — re-encoding those
  would only drop the edge, regressing recall in fluent codebases.
- Part 3: generalize matchJavaCallChain -> matchDottedCallChain (shared by the JVM
  dot-notation languages); resolve the method on the factory's return type, or on
  the constructed class for a Kotlin `Foo(args).method()` receiver. Validated via
  resolveMethodOnType, so a wrong inference yields NO edge.

Validated: synthetic decoy + args + absent-method safety tests; full suite green;
real-repo A/B on arrow-kt/arrow (734 .kt) — node count identical (no explosion),
+49 validated-correct chained edges, and the removed edges are wrong bare-name
guesses the fix correctly stops emitting (419/438 from test/doc files; the 18
from product code are stdlib `.apply{}`, self-loops, and bare-name mismatches) —
a net precision improvement, ~0 correct product edges lost. Java path unchanged
(constructor branch is Kotlin-gated). EXTRACTION_VERSION 6 -> 7.

7f6bdf7ad1 fix(java): resolve chained static-factory calls Foo.getInstance().bar() (#750) (#751)
A Java method called through a static factory or fluent chain — `Foo.getInstance().bar()`,
`Config.create(opts).build()` — lost the receiver's type, so the chained method either
didn't resolve at all or (when a same-named method existed on an unrelated class) attached
to whichever class was indexed first. Ports the #645 (C++) / #608 (PHP) 3-part mechanism:

- Part 1: capture Java return types in the extractor (skip void/primitives/arrays,
  unwrap generics, strip package qualifier).
- Part 2: encode a chained-call receiver as `inner().method` with normalized empty
  parens, so factory calls that take arguments still split.
- Part 3: matchJavaCallChain resolves the chained method on the factory's return type,
  validated via resolveMethodOnType so a wrong inference yields NO edge (never a wrong one).

Validated: synthetic decoy + absent-method safety tests; real-repo A/B on google/guava
(3,227 files) — node count identical (no explosion), 0 edges lost, +1,507 unique chained
edges recovered, precision spot-checked verbatim (Splitter.on().split(),
CacheBuilder.newBuilder().recordStats(), GraphBuilder.directed().build(), nested
MultimapBuilder.linkedHashKeys().arrayListValues()). EXTRACTION_VERSION 5 -> 6.

eb5960b535 fix(php): resolve chained static-factory calls Cls::for($x)->method() (#608) (#749)
A method called through a PHP fluent static factory — `ApiClient::for($c)->createOrder()`,
the canonical Laravel per-credential/per-tenant client idiom — produced no
`calls` edge: the receiver of `->createOrder` is the `Cls::for(...)` static
call, whose result type was never recovered, so the edge was dropped and
`codegraph_callers` returned nothing.

Same shape as the C++ singleton/factory fix (#645), reusing its return_type
column + the chained-call mechanism:
- Capture PHP return types (getReturnType): `: self` / `: static` / `$this`
  stored as the `self` marker, a concrete `: Type` as its short name,
  primitives/unions dropped.
- Encode the chained scoped-call receiver as `Cls::for().method` so the
  resolver can split it (PHP-gated, in extractCall).
- New matchPhpCallChain: look up the factory's return type (`self` → the
  factory's own class; concrete → that class), then resolve AND validate the
  method on it — a wrong inference yields no edge, never a wrong one.

EXTRACTION_VERSION 4->5 (re-index to populate PHP return types + chained edges).

Validated on koel (1383 PHP files): node count identical (no explosion),
0 edges lost, +80 chained-call edges recovered; synthetic tests cover the
self-factory, concrete-return, namespace, decoy, and absent-method cases.

5b3f5e36db fix(go): attribute calls inside top-level closures to the var, not the file (#693) (#744)
A function called only from an anonymous func_literal at package level — a
cobra `RunE: func(){…}` handler, a goroutine literal, a callback closure
stored in a `var` — had its call leak to the FILE node, because the Go
var-initializer walk ran with an empty scope. So `callers`/`impact` showed
the function with a file (or no meaningful) caller, unlike JS/TS where an
arrow-in-const becomes a named node whose calls attribute correctly.

Scope the Go top-level var/const initializer walk to the declared symbol, so
a call nested in any func_literal initializer (struct field, slice/map,
nested closure) attributes to the enclosing var. EXTRACTION_VERSION 3->4
(re-index to pick up the corrected attribution).

Validated on cli/cli (858 Go files): node/edge counts identical, file-level
dependents byte-identical (no regression), and 62 top-level-closure calls
correctly moved from file-attributed to var-attributed.

35b44e242c fix(scan): don't abort indexing on a non-UTF-8 or unparseable .gitignore (#682) (#743)
A .gitignore transparently encrypted in place by corporate DLP / endpoint
software (UTF-16 header + ciphertext), or one containing a pattern the
`ignore` library can't compile to a regex (`\[` -> "Unterminated character
class"), crashed the entire sync/index. The throw is LAZY — it surfaces at
match time (`ig.ignores()`), not `.add()` — so the existing add-time
try/catch never caught it, and the error never named the offending file.

Read .gitignore defensively: skip a file that isn't valid UTF-8 text whole
(NUL byte or fatal UTF-8 decode), drop only the individual uncompilable
patterns from a text one (probe-compile, then per-line fallback), and warn
with the file path. Indexing continues either way. The watcher inherits the
fix via buildDefaultIgnore.

6e2a24d96a fix(extraction): map PHP include/require to file→file dependency edges (#660) (#663)
PHP's importTypes only captured namespace_use_declaration, so
include/require(_once) — the dependency mechanism in procedural and
script-style PHP — never produced edges. callers, impact, and trace
missed the entire file-include graph; only namespace `use` became a
dependency edge.

Capture the four include/require expression types and emit file→file
imports edges, reusing the path-based resolution that C/C++ #include
already goes through. Only static string-literal paths are resolved
(relative to the including file); dynamic forms (include $var,
require __DIR__ . '/x', interpolated strings) are skipped.

Include PATHS are distinguished from namespace `use` symbols by shape: a
path contains '/' or '.', which PHP identifiers and FQNs never do. A
path-shaped include that doesn't resolve to a known project file is left
unresolved and does NOT fall back to the symbol name-matcher, which would
otherwise mis-connect "inc/db.php" to an unrelated db.php elsewhere — a
wrong edge is worse than a missing one.

fd03f31b2c fix(cpp): resolve calls through singletons/factories/chained getters (#645) (#742)
A C++ method call whose receiver is another call's result — `Foo::instance().bar()`,
`WidgetFactory::create().draw()`, `openSession()->run()`, or the same stored in an
`auto` local first — lost the receiver's type during extraction. The callee degraded
to a bare method name, so when two classes shared a method name the call silently
resolved to whichever was indexed first (or not at all), corrupting callers / impact /
trace with a plausible-but-wrong edge.

Three parts:
- Capture C++ return types (new nodes.return_type column, schema v5): the
  function_definition's `type` field, normalized — smart-pointer pointee unwrapped,
  void/primitives dropped.
- Preserve the inner-call receiver in extraction: a C/C++ field_expression whose
  receiver is itself a call is encoded `inner().method` instead of dropping to the
  bare name. Other languages keep the existing behavior.
- New resolution strategy (matchCppCallChain): infer the receiver's class from the
  inner call's return type, then resolve AND validate the method on it. Handles
  singletons/accessors, factories returning a different type, free-function
  factories, make_unique/make_shared/new/direct construction, single-level member
  chains, and namespace-qualified inner calls. A wrong inference yields no edge,
  never a wrong one.

EXTRACTION_VERSION 2->3 (re-index to populate return types).

Validated on the issue repro + spdlog: node count stable (no explosion),
deterministic, and ~100 pre-existing wrong `.size()`-style edges removed.

a56d9e6941 feat(directory): CODEGRAPH_DIR env var to override the index dir name (#636) (#741)
Two environments that share one working tree — most concretely Windows
and WSL — can't safely share a single `.codegraph/`: the daemon lockfile
records a platform-specific pid + socket (named pipe vs Unix socket), and
SQLite locking across the WSL2/Windows filesystem boundary is unreliable,
so two daemons over one index risks corruption.

Add a `CODEGRAPH_DIR` env var (default `.codegraph`) that overrides the
per-project data directory name, so each environment keeps its own index
in the same tree (e.g. `CODEGRAPH_DIR=.codegraph-win` on Windows). The
name is resolved live and validated (rejects separators / `..` / absolute,
falling back to the default with a one-time stderr warning). Indexing and
file-watching now skip ANY `.codegraph-*` sibling so neither side trips
over the other's data.

Routes the previously-hardcoded `.codegraph` literals (db path, lockfile,
error log, watcher ignore, file-scan skip, installer) through the
resolver. No extraction-version bump — index content is unchanged.

636d9fcb7d feat(extraction): index string-literal names in generic tuple type aliases (#634) (#740)
TypeScript service/RPC contracts written as a tuple of generic types —
`type List = [Service<'query_apply_record', Req, Resp>, …]` — carry their
names only as string-literal type arguments, so static extraction never
indexed them and `codegraph query query_apply_record` returned nothing.

Add a narrow TS/TSX type-alias pass that emits each tuple entry's
string-literal name as a `method` node under the alias (qualifiedName
`List::query_apply_record`), making it searchable. Scope is limited to a
direct literal arg of a generic that is a direct tuple element, with a
valid-identifier filter — so utility types (Pick/Omit/Record), deeper
nested generics, and route paths produce no noise.

Bumps EXTRACTION_VERSION so existing indexes get a re-index hint.

112e278b5c fix(security): index config files by key only, never surface values (#383) (#722)
Spring `application.{properties,yml}` keys (and Shopify Liquid `{% schema %}`
blocks) were storing the config VALUE in the node docstring, and
`codegraph_explore`'s source section re-read the raw `key = value` line off
disk — so a secret committed to a config file (DB password, API key, JDBC URL
with embedded credentials) could be pushed into an agent's context via
explore/node output without the agent ever opening the file.

Config-leaf nodes (`kind: 'constant'` in a config language) now surface the KEY
only, via a shared `isConfigLeafNode` predicate applied at both surfacing
paths: the value is dropped from extraction, `getCode`/`includeCode` returns
the key instead of the file line, and explore excludes config leaves from
source rendering. The predicate can't match real code (real constants are
ts/java/go/…), so `@Value`/`@ConfigurationProperties` resolution and impact are
unaffected. Adds a regression test asserting a planted secret never appears in
`codegraph_explore` / `codegraph_node` output while the keys still resolve.

4e5cf2de56 feat(cli): add codegraph upgrade self-update + stale-index re-index hint (#710)
`codegraph upgrade [version]` detects how the CLI was installed — the standalone
install.sh/install.ps1 bundle, npm-global, npx, or a source checkout — and
updates in place: re-running the canonical install.sh on macOS/Linux, an
in-place rename-and-extract swap on Windows (a running node.exe can't be
deleted, only renamed, so the detached-helper approach is avoided), and
npm/npx/source-specific guidance otherwise. Flags: `--check` (report only),
`--force`, and a positional version to pin.

Each full index is now stamped with the engine's EXTRACTION_VERSION in
project_metadata; `codegraph status` (and `--json`) flags an index built by an
older engine and recommends re-indexing, and `upgrade` prints the same reminder.
Gated on EXTRACTION_VERSION so it never nags on extraction-neutral releases.

Validated end-to-end on macOS (real bundle upgrade), Linux (Docker, real
curl|sh) and Windows (Parallels VM, real in-place swap). 32 new unit tests.

Closes #679

629d8472b1 fix(extraction): index Vue <template> component usages (#629 follow-up) (#659)
Vue's extractor parsed only the <script> block, so a component used solely
in another component's <template> (`<MyButton />`) produced no reference —
and thus showed a false 0 callers, even after the barrel-resolution fix in
PR #657. This is the Vue analogue of Svelte's extractTemplateComponents.

extractTemplateComponents() now scans the template (everything outside the
<script>/<style> blocks, which also handles nested <template> tags for
v-if/slots) for component tags:
- PascalCase tags (`<MyButton/>`) — captured as-is.
- kebab-case tags (`<my-button/>`) — converted to PascalCase so they match
  the imported component's name. Safe: an unmatched name creates no edge
  during resolution, so native custom elements just don't resolve.
- Native HTML elements (lowercase, no hyphen) and Vue built-ins
  (Transition, KeepAlive, …) are skipped.

Adds no nodes — only `references` — so node counts stay stable. With this
plus #657, a Vue component re-exported through a barrel and used only in a
template now resolves end-to-end (callers/impact/callees).

Colby MchenryandGitHub 68eaf0dbd8 feat(mcp): codegraph_explore as the sole primary tool + store coverage + overload disambiguation (#647)
## Summary

Completes the explore-overhaul arc: `codegraph_explore` becomes the single primary tool an agent reaches for, and its coverage + output shape are tuned so flow/architecture questions resolve with near-zero Read/Grep.

### What changed
- **explore is the sole primary tool** — removed `codegraph_context` (the fuzzy-input Read-trigger) and `codegraph_trace` (under-picked by agents); explore already surfaces the call flow among the symbols you name. A plain natural-language question now works as the query.
- **Store/handler coverage** — functions defined inside object literals (Zustand `create((set, get) => ({ … }))`, Redux/Pinia/MobX, exported handler/route maps) are indexed as real symbols, including calls through `useStore.getState().fn()` and destructured `const { fn } = useStore.getState()`. A general AST rule, not a per-lib hack.
- **Overload disambiguation** — explore leads with the *right* definition when a method name is overloaded across types (a PascalCase type token in the query biases to that type's own def); `codegraph_node` returns *every* overload's body in one call, with an optional `file`/`line` selector to pin one.
- **Method-atomic render** — explore never returns half a method; at the size budget it drops whole methods/files (and lists what it dropped) instead of truncating a body mid-method.
- **Native-read-shaped output** — per-call output is capped to ~24K with a 25K hard ceiling and concentrated into ~150–250-line flow windows, mirroring how the agent natively reads; repo size scales the *call* budget, not the per-call size (a larger response just gets externalized to a file the host Reads back).
- **Blast radius** folded into explore (dependents + covering tests, locations only).

### Benchmark (refreshed on this build)
Re-validated the 7-repo A/B on 2026-06-02 (Opus 4.8, effort=high, median of 4). WITH arm re-measured on this build, WITHOUT reused:

**~16% cheaper · 47% fewer tokens · 22% faster · 58% fewer tool calls** — 0 file reads on 6 of 7 repos (Gin ~1).

The arc trades larger, cache-heavy explore responses for guaranteed near-zero reads, so cost/token margins soften vs the prior build (Excalidraw and Tokio land at cost break-even) while time and tool-calls stay clear wins everywhere — consistent with the project's stated optimization target (latency + tool-calls, not token cost).

### Validation
- Full suite green: **1112 passed, 2 skipped**.
- 28/28 plain WITH runs across the 7 README repos completed clean; reads median 0 on 6/7.
