Colby McHenryandClaude Opus 4.8 feb2f641de feat(resolution): bridge Laravel event(new X) to its listener handles
Laravel decouples an event dispatch from its listener(s), linked by the event
class: event(new OrderShipped($order)) has no static edge to the
handle(OrderShipped $event) that runs it (usually a separate app/Listeners/
class). laravelEventEdges bridges each event(new X(...)) site -> every
listener's handle for X.

Two registration mechanisms, both real and both needed (built together):
- (A) auto-discovery: a typed handle(EventType $e) first param, read from the
  method declaration source (PHP method nodes carry no signature, like C#); a
  handle(A|B $e) union is split into two events.
- (B) the `protected $listen = [XEvent::class => [Listener::class, ...]]` map in
  an EventServiceProvider, parsed from comment-stripped source (so a
  fully-commented map on an auto-discovery app contributes nothing). This is the
  only way to link a listener whose handle() is untyped.

Job exclusion is free: queued jobs dispatch via ::dispatch()/dispatch() (not
matched) and their handle() takes an injected service, never an event type, so
matching only event(new X) excludes them by construction. `use Dispatchable` is
not keyed on (unreliable in real apps).

Surfaces as `dynamic: laravel event` via the generic synth-edge fallback.

Validated 100% precision on two grep-confirmed repos exercising both
mechanisms: koel (small, populated $listen map, 9 edges incl. the untyped-handle
case and a fan-out) and firefly-iii (large, pure auto-discovery / empty $listen,
141 edges, 0 source/target false positives, 0 namespace mismatch, union split
verified); 0 on the guzzle control. Namespace-agnostic (FireflyIII\ not
hardcoded). Node-stable (pure edge synth). Suite 1623 green.

Colby McHenryandClaude Opus 4.8 2c522c6254 feat(resolution): bridge Sidekiq Worker.perform_async to #perform
Sidekiq decouples a job's enqueue site from the worker's perform method,
linked by the worker class NAME: DestroyUserWorker.perform_async(id) has no
static edge to DestroyUserWorker#perform (usually in app/workers/, away from
the controller/model that enqueues it). sidekiqDispatchEdges bridges each
Worker.perform_async/_in/_at(...) site -> that worker's instance perform.

Name-keyed, like Celery: the receiver class must be a Sidekiq worker, gated by
reading `include Sidekiq::Job|Worker` from the class body (the mixin is an
external gem module that forms no resolvable edge). ActiveJob's perform_later/
_now is a different shape and deliberately not matched.

Namespace disambiguation was the n>1 validation payoff: loomio's flat workers
hid a collision bug that forem exposed (four SendEmailNotificationWorker classes
across modules; simple-name resolution mis-targeted 7/143 edges to the wrong
namespace). Fixed by resolving a namespaced receiver via exact qualified-name
lookup first, falling back to the simple name only for a unique worker — an
ambiguous unqualified collision bails (precision over recall).

Surfaces as `dynamic: sidekiq dispatch` via the generic synth-edge fallback.

Validated 100% precision on two grep-confirmed repos: loomio (medium,
Sidekiq::Worker, 47 edges) and forem (large, both include aliases — 131
Sidekiq::Job + 11 Sidekiq::Worker, 142 edges, 0 worker/source false positives,
0 namespace mismatch); 0 on the jekyll control. Node-stable (pure edge synth).
Suite 1621 green.

Colby McHenryandClaude Opus 4.8 d1381e11f6 feat(resolution): bridge MediatR Send/Publish to its IRequestHandler.Handle
MediatR decouples a _mediator.Send(x)/.Publish(x) call from the Handle method
that runs it, linked by the request/notification TYPE (the IRequestHandler<X,…>
generic), usually across files in a Clean Architecture layout — so flows
dead-end at the mediator call and the agent reads to find the handler.
mediatrDispatchEdges bridges each dispatch -> the matching handler's Handle.

Same two-pass, type-keyed shape as the Spring synthesizer, with two C#-specific
twists found by probing:

- C# method nodes carry NO signature (csharp.ts defines no getSignature), so
  Pass 1 reads the request type from the handler CLASS base-list source
  (`: IRequestHandler<X,…>` first generic arg) and binds the class's Handle.
- The dominant .NET idiom is VARIABLE-passed, not inline `Send(new X)` — eShop
  has zero genuine inline MediatR sends. So Pass 2 resolves the sent type from
  the argument three ways within the enclosing method: inline `new X(…)`, a
  local `var v = new X(…)` (backward scan), or a parameter/local declared `X v`.

Two precision gates: the receiver must be mediator-ish (mediator/sender/
publisher — excludes MAUI MessagingCenter.Send, HttpClient.Send) AND the
resolved type must have a handler (so a same-named non-request DTO is never
bridged). Handles the IdentifiedCommand<T,R> wrapper and void IRequestHandler<T>.

Surfaces as `dynamic: mediatr dispatch` via the generic synth-edge fallback.

Validated 100% precision on two grep-confirmed repos: jasontaylordev/
CleanArchitecture (small, 9 edges, inline + param forms) and dotnet/eShop
(medium, 9 edges, 0 false positives, variable-passed + IdentifiedCommand +
the CancelOrderCommand DTO-collision correctly avoided); 0 on the
Newtonsoft.Json control. Node-stable (pure edge synth). Suite 1619 green.

Colby McHenryandClaude Opus 4.8 9b7ca2e394 feat(resolution): bridge Spring publishEvent() to its @EventListener handlers
Spring decouples an event publisher from its listener(s) through the
application event bus, linked by the event TYPE: publishEvent(new XEvent(...))
has no static edge to the @EventListener void on(XEvent e) that handles it
(usually a different class), so flows dead-end at the publish and the agent
reads to find the handlers. springEventEdges bridges each publishEvent(new X)
site -> every listener of X.

Two-pass, type-keyed (no name resolution, so precision is structural):
- Pass 1 builds Map<eventType, listenerMethod[]> from @EventListener /
  @TransactionalEventListener methods (event type = first param type off the
  node signature, or the @EventListener(X.class) value form) and the older
  `implements ApplicationListener<X>` onApplicationEvent methods.
- Pass 2 links each publishEvent(new XEvent(...))'s enclosing method to every
  listener of XEvent; multi-line `publishEvent(\n new X(...))` handled.

Key Java fact (probed): a method node's range INCLUDES its leading annotations
(startLine is the first @-line, not the `public void` decl), so the annotation
gate scans DOWNWARD from startLine bounded to consecutive @-lines, which can't
bleed into an adjacent method.

Surfaces as `dynamic: spring event` via the generic synth-edge fallback.

Validated 100% precision on two grep-confirmed repos exercising all listener
forms: halo (medium, 1254 java, 33 edges across 24 events, 0 publisher/listener
false positives, param-typed + (X.class) + ApplicationListener + fan-out) and
thombergs/code-examples (4 edges, adds @TransactionalEventListener); 0 on the
gson control (no Spring). Node-stable (pure edge synth). Suite 1617 green.

Colby McHenryandClaude Opus 4.8 6e5c3a9336 feat(resolution): bridge Celery .delay()/.apply_async() dispatch to the task body
Celery decouples a task's call site from its body: a @shared_task / @app.task
decorated def is invoked via task.delay(...) / task.apply_async(...), a dynamic
hop with no static edge, so flows dead-end at the dispatch and the agent reads
tasks.py to reconstruct them. celeryDispatchEdges links the enclosing function
at each .delay/.apply_async site -> the task function body.

Precision rests on a DECORATOR gate: the dispatched name must resolve to a
Python function carrying a task decorator, read from the source lines ABOVE its
def (the def's startLine excludes the decorator, and no decorates edge exists
since @shared_task is an unresolved external import). The kind==='function'
filter drops same-named test-method collisions; canvas forms (group(t).delay(),
t.s()/.si()) have no single identifier before .delay so they're skipped, not
mis-bridged; cross-module name collisions prefer a same-file task else bail.

Surfaces as `dynamic: celery dispatch` via the generic synth-edge fallback.

Validated 100% precision on two grep-confirmed repos exercising both decorator
dialects: paperless-ngx (small, @shared_task, 31 edges, 31/31 real) and pretix
(medium, @app.task, 63 edges across 21 tasks, 0/21 false positives); 0 on the
httpie control (no Celery). Node-stable (pure edge synth). Suite 1615 green.

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 8ea32059b6 feat(resolution): bridge Pinia useStore().action() calls to the action
The dispatch bridge for Pinia, on top of the store-action extraction foundation
(cc9c2f7). A consumer does `const store = useXStore()` then `store.action()` —
a method-on-instance call with no static edge to the action, which lives in the
store module. So tracing "what does this view do when it loads" stopped at the
`store.fetchUser()` line.

piniaStoreEdges (callback-synthesizer.ts): map each `const useXStore =
defineStore(...)` factory → its file; per consumer file, bind `const s =
useXStore()` vars; link the enclosing function (or the .vue component, via a
fallback) → the `s.method()` action node IN THE STORE'S FILE. The same-store-file
gate is the precision lever — a Pinia built-in (`$patch`) or an unrelated
same-named method resolves to nothing. Covers the options and setup store forms
uniformly (the action is a function node in the store file either way) and
surfaces in explore as `dynamic: pinia store`.

Validated 100% precision (Geeker 41 edges, MallChat 64; 0 targets outside a
store file), 0 on the Vuex-only element-admin control (no defineStore), n=2 in
hand. Suite green (1612); new __tests__/pinia-store-synthesizer.test.ts. The
Vuex string-key dispatch bridge (`dispatch('ns/action')`) remains a follow-up
(n=1 in hand — needs a 2nd string-literal Vuex repo).

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).

Colby McHenryandClaude Opus 4.8 7f970296cf feat(resolution): synthesize object-literal registry dispatch edges
Adds `objectRegistryEdges` — a dynamic-dispatch synthesizer for the command/handler
registry pattern: an object literal maps string keys → handler classes/functions, then
dispatches by a RUNTIME key static parsing can't follow:

    this.commands = { [Cmd.ADD]: AddObjectCommand, ... }    // registration
    new this.commands[command](args).execute()              // dynamic dispatch

It links each dispatching function → each registered handler's callable entry (a class's
execute/run/handle method — preferring the method chained at the dispatch site — or the
function value), like the gin-middleware-chain fan-out. Same-file registry+dispatch only.

Validated precise on 3 real repos (the discipline that caught redux-thunk's n=1 overfit):
EtherealEngine's CommandManager (64 edges, class registry → .execute), Prebid.js (7:
builder/consent/message dispatch, function registry), warp-drive (1). Zero false positives
after several precision gates found during validation:
- skip minified/generated bundles (avg line length > 200) — draco/three.min were a
  false-positive minefield of `h[x](...)` calls + `{a:b}` literals;
- DEPTH-AWARE entry parsing (top-level `key: Identifier` only) so method-shorthand bodies
  and nested objects don't leak their inner `k: v` pairs as bogus handlers;
- callable-only targets (drop data `constant`s — a `{x: URL}` entry resolving to the global);
- dynamic-dispatch gate (a statically-accessed look-alike object yields nothing).
Handles constructor and field-initializer registry forms (this. normalized). Surfaces in
codegraph_explore via the existing Dynamic-dispatch-links section.

Deferred (recall, documented in dispatch-synthesizer-backlog.md): assign-then-call dispatch,
augmentation registration (reg[k]=H), and the cross-file barrel-namespace variant
(trezor getMethod) — the hard tier.

Full suite green (1606); new __tests__/object-registry-synthesizer.test.ts.

Colby McHenryandClaude Opus 4.8 270e50655a fix(explore): surface synth constant-endpoint edges + precise redux-thunk dispatch resolution
Two fixes hardening the redux-thunk dynamic-dispatch synthesizer, found by
validating it on real RTK repos beyond its trezor origin (uwave-web,
session-desktop, octo-call):

- Surfacing: buildFlowFromNamedSymbols filtered its named set to CALLABLE
  kinds, so synthesized edges between `constant` nodes (RTK thunks are
  `const X = createAsyncThunk(...)`) never entered the Flow / Dynamic-dispatch
  links scan — invisible at every tier, while the kind-agnostic Relationships
  section is off below 500 files. Add a `dynNamed` set (named constant/variable/
  field nodes with a heuristic edge) feeding a shared collectSynthLinks into the
  "## Dynamic-dispatch links" section, threaded through the named.size<2
  early-out (both-endpoints-constant hit return EMPTY first) and the main path.
  Main call-chain stays callable-only; the <500 budget tiers are untouched.
  No-op for callable flows. Plus a generic synthEdgeNote fallback so any synth
  hop reads "dynamic: <kind> @site", not a bare "[calls]".

- Precision: reduxThunkEdges resolved a dispatched name by first-match-by-kind,
  so a thunk name colliding with a same-named service function linked to the
  wrong node (octo-call `leaveCall`). Prefer thunk-signature const > other
  const > same-file callable > first match.

Tests: new explore-synth-constant-endpoints.test.ts (surfacing on a small repo)
+ a collision case in redux-thunk-synthesizer.test.ts. Full suite green (1605).
Rationale + coverage backlog in docs/design/dispatch-synthesizer-backlog.md.

Colby McHenry e5897d0334 feat: remove reasoning offload / CodeGraph AI managed reasoning feature
Strips the bring-your-own-model reasoning offload and managed CodeGraph AI
integration (login/logout/usage commands, offload config/credentials/reasoner
modules, and the synthesizeOffload call in codegraph_explore). The eval findings
showed raw source output outperformed the synthesized path on accuracy, so
codegraph_explore reverts to returning verbatim retrieved source exclusively.

CHANGELOG and README sections for reasoning offload are removed; test comments
and DEFAULT_MCP_TOOLS description are updated to drop offload references.

Colby McHenry e7d9f8c6fa feat(explore): surface interface/registry dispatch boundaries and window oversize spine methods
Two gaps closed in `codegraph_explore` output quality:

**Interface/registry dispatch (#687 extension).** When a named token resolves to
a large same-name family (≥8 members) that doesn't land on the connected flow, the
static path truly ends there — the target is chosen at runtime from N implementations
(plugin/strategy/handler interface). `buildPolymorphicBoundaries` detects this via
`implements`/`extends` edges, ranks candidate supertypes by their TRUE graph-wide
implementer count (not FTS sample frequency, which is biased), and emits a
"## Interface dispatch" section naming the supertype, implementer count, and a few
concrete targets. Fires only for uncovered named tokens; a connected flow stays silent.

**Oversize spine method windowing.** A flow entry that is a god-method (e.g. n8n's
962-line `processRunExecutionData`) previously lost the per-file budget to denser
peripheral blocks and was dropped, forcing the agent to `Read` it back. The spine
call site (edge line to the next hop) is now tracked via `spineCallSites` and used
to window the method to its signature head + a ±28-line band around the call, keeping
it under the OVERSIZE_SPINE_LINES threshold. Spine clusters also rank first in the
budget sort and may exceed the per-file cap up to a 2.5× ceiling so they can never be
starved by co-flow files.

Test suite gains an `interface dispatch` describe block (announce, silent-on-connected,
silent-below-threshold) and uses `beforeAll`/`afterAll` to pin `CODEGRAPH_OFFLOAD_DISABLE=1`
so structural assertions are hermetic regardless of machine config.

Colby McHenry 6d5cb6b25c feat(reasoning): add CODEGRAPH_OFFLOAD_DISABLE kill-switch and per-call usage log
`CODEGRAPH_OFFLOAD_DISABLE=1` immediately disables the offload for the current
process without touching the persisted config or stored login — useful for A/B
arms or sessions where raw source is preferred.

`CODEGRAPH_OFFLOAD_USAGE_LOG=` appends one JSONL entry per call with token
counts, charged credits, and derived cost (`creditsCharged / 100_000`) so a
harness can attribute CodeGraph AI spend to a single run independently of the
server's cumulative totals. Both features are best-effort and never disrupt the
degradable offload path.

Also fixes the `login` credit display to check `unlimited` before the numeric
balance, so comped/internal accounts don't incorrectly show "0 remaining".

Colby McHenryandClaude Opus 4.8 da5c6c2f79 feat(offload): managed tier (CodeGraph AI) — metered reasoning via org token [WIP]
Adds the managed offload mode: point codegraph_explore at the CodeGraph AI metered
gateway (https://ai.getcodegraph.com) with an org token instead of a BYO provider key.
Same synthesis client, pointed at codegraph-ai-proxy (a metered OpenAI-compatible gateway).

- credentials.ts — org token in ~/.codegraph/credentials.json (0600); unlike a BYO
  provider key it's a revocable org-scoped auth token (gh/npm-login style), kept out
  of config.json
- config.ts — managed branch in resolveOffload: default gateway URL + public model id
  (openai/gpt-oss-120b) + login token as bearer; managed requires a token to be enabled
- reasoner.ts — fetchUsage() reads the credit balance from /v1/usage
- bin/codegraph.ts — `codegraph offload login --token <t>` / `logout`; status shows the
  managed tier + live balance

Proven GREEN end-to-end against a local wrangler-dev of the proxy: org token validated,
credits prechecked, real Cerebras synthesis returned, and credits metered + charged
(250,000 → 248,473). Graceful degrade on upstream failure; balance via /v1/usage.
Phase 3 (codegraph login device flow) replaces the manual --token.

Colby McHenryandClaude Opus 4.8 db4c9f3641 feat(offload): reasoning offload for codegraph_explore (bring-your-own endpoint)
codegraph_explore can now hand the source it retrieved to a reasoning model you
point at — any OpenAI-compatible endpoint (Cerebras, OpenAI, a local vLLM/Ollama)
with your own key — and return that model's tight, cited answer instead of the
raw source dump. The agent's main context gets the answer in far fewer tokens, at
the cost of one network round-trip.

Off by default. Configure with `codegraph offload set-endpoint <url> --model <m>
--key-env <ENV>` (or the CODEGRAPH_OFFLOAD_* env vars); status/disable manage it.
The API key is never written to disk — the config stores the NAME of an env var
and the key is read from it at call time. Strictly degradable: any failure
(no endpoint, network, timeout, empty answer) returns null and the call falls
back to the local source, so the offload can never surface an error to the agent.

Colby McHenryandClaude Opus 4.8 798cd0e21c fix(explore): keep multi-term backend files from being buried by a denser frontend layer
codegraph_explore's file sort is primarily driven by Random-Walk-with-Restart
graph-centrality mass, seeded from the query's text matches. In a cross-layer
monorepo (an API server alongside a much larger, internally dense frontend that
mirrors the same domain words), that mass skews to the bigger layer — so a
backend service/handler that genuinely matches several query terms, even when
it's the #1 search hit, sorts below hits=0 frontend files and gets truncated out
of the response, and the agent reads it back.

Add a corroboration tier above the graph signal: a file that is BOTH an
entry/central file AND matched by >=2 distinct query terms is kept in. The
entry/central guard prevents an incidental multi-term file (a type/util file
that isn't the flow) from displacing a graph-central answer file — a blunt
hits-only tier regressed that case. Single-layer repos are unaffected. Gated by
CODEGRAPH_RANK_NO_MULTITERM=1.

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.

b49147eab0 fix(cli): make codegraph index a full rebuild so it stops reporting 0 nodes (#874) (#894)
`codegraph index` ran extraction against the already-populated DB without
clearing it first. On an unchanged tree every file's content hash still
matched, so the orchestrator skipped re-inserting all of them and the run
reported its delta (after - before = 0) as "0 nodes, 0 edges" — which read as
if `index` had wiped the graph. `init` only ever differed because it runs on a
freshly created, empty DB.

Clear the existing graph before re-indexing so `index` rebuilds from scratch
and reports the same complete result as a fresh `init`. `--force` keeps its
role as the home-dir/root-path override; `sync` stays the incremental path.

Adds an end-to-end regression test driving the built binary (init -> index),
asserting the graph stays populated and the summary is never "0 nodes, 0 edges".

ab107b325a fix(watcher): warn (don't degrade) on Linux inotify watch exhaustion (ENOSPC) (#893)
On the Linux per-directory watch path, hitting fs.inotify.max_user_watches
surfaces as ENOSPC — which the degrade logic added for #876 (EMFILE/ENFILE
only) did not catch, so it fell through to the silent "skip this directory"
branch: a large repo got a partial watch set with no hint why edits in
unwatched directories stopped auto-syncing.

ENOSPC is non-fatal — raise the limit and partial watching keeps working — so
it now warns ONCE, naming the exact knob (fs.inotify.max_user_watches, with the
sysctl to set it), instead of degrading. It also stops attempting further doomed
watches for the session (every inotify_add_watch would fail too). Installed
watches keep firing; `codegraph sync` / git sync hooks cover the remainder.

Validated on macOS (forced per-directory path) and real Linux (Docker) — the
new test asserts a single warning naming fs.inotify.max_user_watches, no
degrade, and a live partial watch.

beca7116a0 feat(mcp): surface degraded watcher state to the agent in tool responses (#892)
When live file watching permanently degrades (watch-resource exhaustion, or a
write lock held past the retry budget), getPendingFiles() goes empty — so the
existing per-file staleness banner can't fire even though the index is now
frozen and silently drifting stale. The agent kept getting clean-looking
responses off a no-longer-updating index.

Read-tool responses now lead with a whole-index banner ("CodeGraph auto-sync
is DISABLED…") whenever the watcher is degraded, and codegraph_status gets a
dedicated "Auto-sync disabled" section. Both carry the degrade reason and tell
the agent to Read files directly. Expose isWatcherDegraded() /
getWatcherDegradedReason() on the CodeGraph class, and document the new banner
in the MCP server instructions.

Completes the agent-notification half of #876 (the operator-facing onDegraded
wiring shipped in #891).

cea4d086f9 fix(watcher): degrade cleanly on watch exhaustion and prolonged lock contention (#891)
The live file watcher could stay "alive" after it had stopped being
trustworthy. EMFILE/ENFILE watch-resource exhaustion only logged (and was
silently tolerated on the Linux per-directory path), and prolonged
LockUnavailableError retried forever at the normal debounce cadence — both
left auto-sync dead while the index silently drifted stale. Especially bad
for long-running MCP/daemon sessions.

Add a one-way degrade(): on watch-resource exhaustion (any watch strategy)
or on lock contention past a bounded exponential-backoff budget, log once,
fire a new onDegraded callback, and stop. start() now returns false
consistently when the per-directory path degrades at startup — it previously
returned true on Linux, so the MCP server reported the watcher "active" when
it had degraded. Wire onDegraded into the MCP server so callers are actually
told, and expose isDegraded()/getDegradedReason().

Builds on the approach in #877 by @thismilktea. Validated on macOS
(recursive), Linux (per-directory, Docker) and Windows (recursive) — 30/30
watcher + watch-policy tests on each.

Closes #876

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.

64ff7597d0 fix(cli): stop serve --mcp from confusing humans — hide it + explain on a TTY (#867)
`codegraph serve --mcp` is the stdio MCP server an AI agent launches for itself
(the installer wires it into every agent's MCP config), not a command a human
runs. Run by hand in a terminal it just hung waiting for JSON-RPC, looking
broken.

- Hide `serve` from `--help` (commander `{ hidden: true }`); it stays fully
  invocable, so agents are unaffected.
- When stdin is an interactive TTY (a person — never the agent's pipe or the
  detached daemon), print what it is and point to `codegraph status` /
  `codegraph daemon`, then exit instead of hanging.
- README: drop `serve --mcp` from the CLI Reference and stop the troubleshooting
  section from telling users to run it; keep the accurate "your agent launches
  it" note.

Verified: agent path intact (22 MCP handshake/daemon tests pass), `serve` absent
from --help, and the TTY path prints the message and exits cleanly.

f7441f2124 fix(resolution,cli): cross-file static method calls + affected path normalization (#825) (#865)
Cross-file `ClassName.staticMethod()` calls resolved to the class, not the
method: the import resolver matched the receiver `Foo` to the named class
import but dropped the `.bar` member, and createEdges then mis-promoted the
`calls` edge to `instantiates`. So callers/impact for the static method came
back empty. Descend from the resolved class into its `Container::member` so the
call links to the method; fall back to the class when no such member exists
(non-`::` languages and genuine class references are unaffected).

Also normalize `codegraph affected` inputs to the project-relative,
forward-slash form the index stores, so `./src/x.ts`, an absolute path, and a
Windows back-slash path all match (previously silently returned 0).

Validated on luxon (24 files): node/edge totals identical (no explosion), 69
mis-promoted `instantiates` edges become `calls`, and real static factories
(DateTime.fromISO, etc.) resolve their callers. Full suite: 1534 passed.

070ce4da2b feat(cli): codegraph version command + complete CLI Reference (#864)
* feat(cli): codegraph version command + complete CLI Reference

Add a `codegraph version` subcommand plus the `-v` and `-version`
spellings (commander already wires up `--version`/`-V`), so the version
is easy to reach however a user guesses at it. The `-v`/`-version` forms
are intercepted before commander parses — its version short flag is the
capital `-V`, and its parser rejects a multi-character single-dash flag.
A trailing `-v` on a subcommand still means `--verbose`.

Document the previously-missing commands in the README CLI Reference:
`daemon`/`daemons`, `unlock`, `telemetry`, `version`, and `help`.

Colby MchenryandGitHub ff288ac711 feat(cli): one interactive codegraph daemon command, replaces stop/list (#863)
Collapses the unreleased daemon controls into a single interactive command.
`codegraph daemon` (alias `daemons`) opens an arrow-key picker (current project's
daemon first, pre-selected), enter stops it, or pick "Stop all"; non-TTY prints a
plain list. Removes stop/list/ps; reuses the unchanged daemon-registry machinery;
the pick->stop loop is in daemon-manager.ts behind an injectable select (unit
tested). Validated live on macOS/Linux (real clack picker driven via pty) and
Windows (real runDaemonPicker + stopDaemonAt against a real daemon). Closes #845
follow-up.

Colby MchenryandGitHub 0f825649a1 feat(cli): codegraph stop / list to manage background daemons (#861)
Adds first-class daemon control (the #845 pain point: no clean way to stop a
runaway daemon). `codegraph stop [path]` stops the current/given project's
daemon (SIGTERM -> SIGKILL fallback, sweeps artifacts); `stop --all` stops every
daemon; `list`/`ps` shows running daemons (--json for scripts).

Discovery via a small self-healing registry: each daemon records its root under
~/.codegraph/daemons/ on start, removes it on graceful shutdown; readers prune
dead pids. Cross-platform by construction (files + process.kill). Validated live
on macOS, Linux (docker), and Windows (VM): registry unit 6/6 and real-daemon
stop/list 6/6 on each.

Colby MchenryandGitHub 2472508549 fix(installer,cli): refuse to index $HOME / filesystem root (#860)
Running the installer or `codegraph init`/`index` from $HOME auto-indexed the
entire home tree (installer indexes process.cwd() with no guard), producing a
multi-GB ~/.codegraph/codegraph.db; the install dir sharing the ~/.codegraph
name then made every home subdir resolve its root to $HOME. On pre-1.0 macOS the
per-file watcher over that tree exhausted kern.maxfiles and crashed the machine
(#845; the fd blowup was fixed in 1.0.0, this fixes the root cause).

Add unsafeIndexRootReason() and refuse the home dir, a parent of home, and
filesystem roots at the installer auto-index, `init`, and `index`. Overridable
with --force. Closes #845.

Colby MchenryandGitHub 484da77296 test(mcp): make liveness-watchdog kill assertions cross-platform (#859)
Validated the watchdog on the Windows VM: it kills a wedged process correctly,
but Windows has no real signals — process.kill(pid,'SIGKILL') maps to
TerminateProcess, seen as signal=null + non-zero code, not 'SIGKILL'. Assert
"killed" platform-agnostically and require the own exit code in the opt-out test.
Source watchdog unchanged. Windows: fatal-handler 8/8, liveness-watchdog 7/7,
mcp-daemon 9/9; mcp-initialize EPERM is pre-existing (identical with watchdog off).

Colby MchenryandGitHub 1702dfc544 fix(mcp): make the liveness watchdog a separate process, not a worker thread (#858)
The worker-thread watchdog from #856 didn't work in the real daemon — caught by
live-testing against a real serve --mcp. V8 isolates coordinate on global
safepoints, so a main thread wedged in a tight non-allocating loop (#850's
SourcePositionTableIterator::Advance) strands the watchdog worker before it can
SIGKILL.

A separate child process shares no isolate/heap with the parent, so the wedge
can't touch it; it kills via the kernel. Parent heartbeats to the child's stdin;
silence past the timeout -> SIGKILL; parent exit closes the pipe -> child exits.
Validated live (real daemon SIGKILLed in ~timeout); regression test covers the
non-allocating-wedge-under-heap-pressure case. API/install points/CHANGELOG
unchanged; the broken worker version was never released.

Colby MchenryandGitHub 576149e062 feat(mcp): worker-thread liveness watchdog to self-kill a wedged main thread (#856)
Belt-and-suspenders follow-up to #855. Any non-yielding sync loop on the main
thread wedges the event loop, and nothing running on that loop (timers, signal
handlers, PPID watchdog) can recover it — only another thread can.

A tiny worker thread (in the detached daemon + direct modes) watches a
shared-memory heartbeat the main thread bumps each event-loop turn; if it stops
advancing across enough consecutive checks (~CODEGRAPH_WATCHDOG_TIMEOUT_MS,
default 60s) the worker SIGKILLs the process so a fresh daemon starts on the next
connection. Counts consecutive stale checks (not wall-clock) so it's immune to
clock jumps / sleep; tuned never to fire on real work; opt out with
CODEGRAPH_NO_WATCHDOG=1.

Colby MchenryandGitHub 3476ac9a27 fix(mcp): exit on uncaught exception instead of orphaning/spinning at 100% CPU (#855)
The process-wide uncaughtException handler logged the error and kept running. For
the detached `serve --mcp` daemon that turned any escaped fault into an
unrecoverable orphan: nothing respawns it, and when logging the raw Error hit a
V8 source-position loop while lazily formatting `.stack`, the main thread wedged
at 100% CPU so even the PPID watchdog / idle-timer could no longer fire. Same
failure mode as #799, which only fixed the stdin-'error' trigger.

Restore Node's default fatal semantics: render a bounded, hang-proof line (name +
message only — never read `.stack`) then exit non-zero, so a fresh daemon starts
on the next connection. Extracted to src/bin/fatal-handler.ts with injectable
seams; unit-tested incl. the never-touch-stack invariant.

Closes #850.

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).

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.

* fix(installer): opencode global config goes to ~/.config/opencode on every platform (#535)

opencode resolves its config dir with xdg-basedir (XDG_CONFIG_HOME ??
~/.config) unconditionally — it never reads %APPDATA%; that layout
belonged to the discontinued Go fork. Writing there on Windows meant
opencode never saw the MCP entry.

- globalConfigDir(): drop the win32 APPDATA branch; XDG resolution everywhere
- install/uninstall (global): sweep a stale codegraph entry + AGENTS.md block
  out of the legacy %APPDATA%/opencode location (siblings/comments untouched)
- detect(global): a legacy-only dir still counts as installed so the sweep
  is reachable
- tests are env-gated, not platform-gated, so the whole matrix runs on any
  OS; the suite previously pointed APPDATA and XDG_CONFIG_HOME at the same
  dir, which is exactly how the divergence stayed invisible

Supersedes the prefer-if-exists approach of #670 (greenfield installs --
before opencode's first run -- would still have fallen back to APPDATA).

df6f4bec43 feat(explore): dynamic-dispatch boundary surfacing — announce where a flow ends instead of guessing edges (#687) (#835)
* feat(explore): announce dynamic-dispatch boundaries when a flow can't connect statically (#687)

When buildFlowFromNamedSymbols can't connect the agent's named symbols, scan
the disconnected symbols' bodies (query-time, deterministic, zero graph
mutation) for dynamic-dispatch forms — computed member calls, getattr,
reflection, typed message buses, runtime-keyed emits, Proxy — and announce
the exact site where the static path ends, with candidate runtime targets
when a dispatch key is statically visible. The honest alternative to
guessing edges: surface the boundary, don't fabricate the bridge.

A 2-node chain populates pathIds but renders nothing (Flow needs >=3), and

848fde9f59 feat(telemetry): anonymous usage telemetry — documented schema, opt-out, public ingest worker (#834)
Adds anonymous usage statistics (commands/tools used, languages indexed,
connecting agents) with a strict, auditable allowlist. Never code, paths,
file/symbol names, queries, or IPs.

- src/telemetry/: zero-dep client — consent resolution (DO_NOT_TRACK >
  CODEGRAPH_TELEMETRY > stored choice > default-on), random machine UUID,
  in-memory counters → capped JSONL buffer → completed-day rollups; sync
  exit-append (survives process.exit) + opportunistic bounded sends; the
  first-run notice gates the first SEND, never local buffering, so the
  installer's consent toggle always precedes it. Off is off: no recording,
  no socket, buffered data deleted.
- codegraph telemetry status|on|off; per-command counting via preAction hook.
- MCP: tool counting after the reply is on the wire (session + proxy
  in-process fallback), agent attribution from initialize clientInfo,
  unref'd daemon flush interval. Zero hot-path cost, zero stdout.
- Installer: visible default-on consent toggle (asked once, never re-asked),
  install/index/uninstall lifecycle events.
- telemetry-worker/: public Cloudflare Worker behind telemetry.getcodegraph.com
  — allowlist validation, IP stripping, per-machine rate limit, forwards to
  PostHog as anonymous events. Ships nowhere with the npm package.
- TELEMETRY.md (field-by-field contract) + README section + design doc.
- 20 unit tests; suite-wide CODEGRAPH_TELEMETRY=0 guard so tests never
  pollute real telemetry. Full suite: 1448 passing.

8170d181f2 feat(cli+installer): codegraph explore/node CLI + instructions-file block — subagent & non-MCP reach (#704) (#819)
Task-tool subagents never see the MCP initialize instructions and hold
the MCP tools only as deferred names they rarely think to load — so
delegated work bypassed codegraph almost entirely (measured ~1 of 9
forced-delegation runs touched it; the rest did 30-50 grep/read calls).
Two additions close the gap:

- CLI: `codegraph explore` and `codegraph node` call the same ToolHandler
  as the MCP tools and print identical output — the graph for any agent
  with a shell (subagents, Gemini CLI, raw Codex, humans).
- Installer: each agent target (claude/codex/gemini/opencode) writes a
  short marker-fenced CodeGraph section into its instructions file —
  the one channel subagents DO receive — naming both surfaces. Upsert
  self-heals the stale pre-#529 long block; uninstall strips it; re-runs
  are byte-equal unchanged. (#529's duplication argument bounded the
  size: four lines, commands only.)

A/B (excalidraw, sonnet/high, forced Explore-agent delegation): without
the block, subagent codegraph usage ~1/9 runs; with it, 4/4 — subagents
ToolSearch-load the MCP tools and run explore 5-7x, best runs with ZERO
Read/grep (80-95s vs 150-197s baseline). The block's mechanism: the
parent relays the note into the task prompt, making the deferred tool
names salient.

Contract tests updated to the new expectations (write + self-heal
replace the #529 strip-only behavior); README install/guidance sections
refreshed (they also still described the pre-#817/#818 tool surface).

callees/impact/files/status stay fully functional (handlers, CLI, library
API untouched; CODEGRAPH_MCP_TOOLS re-enables any) but are no longer
LISTED by default. Evidence: codegraph_impact appears in zero recorded
eval runs ever; its blast-radius info already arrives inline on explore
(Blast radius section) and node (dependents note). callees is redundant
by construction (a symbol's body IS its callee list). files/status
"reduce to one grep" per the tiny-repo audit, and staleness banners
already inline pending-sync. callers stays: exhaustive call-site
enumeration (incl. callback registrations, per-definition sections) is
the one job explore/node don't replicate. Fewer tools = fewer mis-picks
+ ~300 schema tokens saved per session; presence itself steers.

server-instructions rewritten around the 4-tool surface ("what does X
call" → node body+trail; "what breaks" → callers + inline blast radius).
Tiny-repo gate unchanged (its trio ⊆ the default set); stale gate
comment corrected (context/trace are long gone — its "5 core tools" are
today's trio).

f9fcc2cd6a feat(mcp): unindexed sessions go quiet — empty tools/list + inactive instructions, no-error policy (#769) (#817)
An MCP session in a workspace with no .codegraph/ previously got the full
"lean on codegraph for everything" playbook plus all 8 tools, then every
call returned isError — and one or two early errors teach an agent to
abandon codegraph for the whole session (maintainer-observed). Now the
initialize response picks an instructions variant by index state (cheap
sync walk-up, #172 respond-fast contract holds) and tools/list serves an
EMPTY list when unindexed: absence is the one signal an agent can't
misread. Indexing is deliberately the user's call — the inactive note
tells the agent not to run init itself.

No-error policy in the tool handler: expected/recoverable conditions
(NotIndexedError — cross-project query to an unindexed path, default-
project detection miss) return SUCCESS-shaped guidance instead of
isError; security refusals (PathRefusalError) stay hard errors without
retry encouragement; genuine internal failures keep isError but add a
retry-once note so a transient blip doesn't convert to permanent
abandonment. Principle recorded in CLAUDE.md.

Also: codegraph_search kind:"type" (advertised by its own schema enum)
silently matched nothing — now maps to type_alias; codegraph_explore's
query param no longer tells agents to run codegraph_search first
(contradicted explore's call-FIRST design); server-instructions
§Limitations rewords the unindexed case to stay-out-for-the-session.

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).
