Vendor tree-sitter-c-sharp 0.23.5 (ABI 15) for C#, replacing the bundled ABI-13
build that dropped primary-constructor classes. Adds native primary-ctor
parsing, primary-ctor parameter dependency edges, return-type extraction via the
renamed `returns` field, and a preParse that blanks `#if` directive lines the
new grammar mis-parses inside enum bodies. Validated on MediatR / eShopOnWeb /
Newtonsoft.Json + full suite.

Add a resolution-phase pass (goCrossFileMethodContainsEdges) that links a Go
method to its same-named receiver type within the same package (= directory),
so a method declared in a different file from its `type` is no longer orphaned
from the struct. Runs before goImplementsEdges so cross-file methods also count
toward interface satisfaction (#584). Adds a regression test + CHANGELOG entry.

Give resolvePythonModuleMember the same absolute-dotted-path fallback that
resolveModuleImportToFile already uses, so a `module.func()` call after
`from pkg import module` / `import pkg.module as module` records its `calls`
edge. Adds a regression test and a CHANGELOG entry.

When an MCP host (opencode and others) SIGTERM's the shared daemon as a new
session starts, the existing session's proxy used to exit on the dropped socket
— silently losing CodeGraph for that session, and hanging any request in flight
at the drop. The SIGTERM originates in the host's process-tree teardown, not in
CodeGraph (nothing here signals another process), so the fix is proxy
resilience, not chasing the signal.
The local-handshake proxy now treats a daemon disconnect as recoverable rather
than terminal: it falls back to its in-process engine for the rest of the
session (the same path used when no daemon is reachable at startup, and what
CODEGRAPH_NO_DAEMON does) and re-serves any requests that were in flight to the
dead daemon, so the host never hangs. The proxy still exits when the HOST goes
away (stdin close / PPID watchdog) — only daemon loss is now non-fatal.
Also replaces the over-the-wire liveness-sweep test added in #712 — which was
flaky under heavy parallel load (a raced raw-socket connect) — with a
deterministic Daemon.reapDeadClients unit test. The client-hello round-trip is
still exercised by every daemon test (the real proxy now sends it).
Validated with a reproduction (proxy stays alive, in-flight request answered,
post-drop request recovers) and a regression test in mcp-daemon.test.ts.
Confirmed on macOS (full suite green) and a Windows 11 VM.

Layer-2 defense-in-depth follow-up to the Windows PPID watchdog fix (#711).
That fix makes an orphaned proxy exit so its socket closes and the daemon
reaps via the refcount + idle timer. This adds two daemon-side safety nets for
the residual case where a socket close is never delivered (a Windows named-pipe
hazard) and a phantom client would otherwise pin the daemon forever:
- Liveness sweep: a proxy now sends an optional client-hello carrying its pid
(+ host pid) right after verifying the daemon hello; the daemon periodically
drops any client whose peer process is dead, re-arming the idle timer.
Fail-safe and version-pinned — a connection that never sends the hello just
falls back to the socket-close lifecycle, and the daemon reads it before the
transport so a non-hello first line is handed through untouched.
- Inactivity backstop: the daemon exits after a generous no-traffic window
(CODEGRAPH_DAEMON_MAX_IDLE_MS, default 30 min) even with clients attached, so
a phantom client that sends nothing can't keep it alive.
Pure helpers (parseClientHelloLine, peerIsDead) are unit-tested; the full
handshake + sweep and the backstop are covered end-to-end in mcp-daemon.test.ts.
Validated on a real Windows 11 VM: the sweep reaps a dead-pid client over a
named pipe and the backstop fires with a client still connected.

On Windows the PPID watchdog could never fire: orphans aren't reparented, so
`process.ppid` stays constant after the parent dies (defeating the ppid-change
check), and the standalone bundle pre-bakes `--liftoff-only`, skipping the
relaunch that sets `CODEGRAPH_HOST_PPID` (defeating the host-liveness check).
With neither signal available, an orphaned proxy / direct server ran forever,
the shared daemon never saw the client disconnect, and its idle timer never
armed — node processes accumulated until CPU saturated.
Add a win32-only signal: poll the original parent's liveness directly, since
ppid is stable there. Gated to Windows so POSIX double-fork cases keep relying
on the ppid-change signal (a dead original parent is not proof of orphaning on
POSIX). The decision is extracted into a pure, unit-tested helper shared by all
three watchdog sites (proxy socket, proxy local-handshake, direct mode).
Validated on a real Windows 11 VM: in the exact bundle scenario (direct mode,
no HOST_PPID) an orphaned server now exits within one watchdog poll via the new
path; the POSIX reparent path is unchanged and its integration test still passes.

`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.

Replaces the plain oxblood-filled rectangle + system-font text SVG with a
polished button that matches the getcodegraph.com design language:
- Cream (#f7f6f2) rounded-rect background with a soft hairline border, 8px
radius, 52px height
- Logo mark (graph triangle, mirrors favicon.svg) in ink/oxblood at left
- Hairline divider separating mark from label
- "Join the waitlist!" label rendered as vector outlines (Archivo Bold 760,
17.5px) so the brand typeface renders correctly on GitHub, which blocks
@font-face in statically-served SVGs
- Oxblood arrow at right
Adds assets/generate-waitlist.py (requires fonttools + brotli) so the SVG
can be regenerated from the landing-page's Archivo variable font. Updates
the README img height from 44→52 to match the new geometry.
Advertise the upcoming hosted CodeGraph platform at the top of the README with a "Join the waitlist" CTA (early beta access) linking to getcodegraph.com, plus the button SVG asset.

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).

Component barrels (`export { default as X } from './X.svelte'`) and
monorepo workspace imports (`@scope/ui/widgets`) left the consumer↔component
edge uncreated, so live components showed a false `0 callers` — the canonical
dead-code signal — risking deletion of live code.
The Svelte default-barrel case broke at FOUR layers, each of which alone left
it unresolved:
- findExportedSymbol matched only function/class for a default export, never
`component` (Svelte/Vue SFCs are kind 'component').
- extractImportMappings had no svelte/vue branch, so SFC consumers produced
zero import mappings and resolveViaImport never ran.
- EXTENSION_RESOLUTION had no svelte/vue entry, so relative imports from an
SFC (`./lib` -> `/index.ts`) resolved to nothing.
- getReExports parsed the barrel in the CONSUMER's threaded language, so a
.svelte consumer made extractReExports bail on a .ts index barrel.
Workspace package-subpath barrels get a new workspace-packages module
(mirrors go-module/path-aliases): reads package.json `workspaces`
(npm/yarn/bun) + pnpm-workspace.yaml, maps member name->dir, resolves
`@scope/ui/widgets` -> `packages/ui/widgets`. Gated behind the workspaces
field so single-package repos are unaffected.
Bare `./`/`.` directory imports already resolved; covered with a regression
test. Verified both directions (callers/impact AND callees) for Svelte; Vue
script-level imports also resolve. 4 new tests; full suite green (1126).

Batch of small, localized fixes from an open-issue triage:
- .codegraph/.gitignore now ignores everything but itself, so the database,
daemon.pid, sockets, and logs stop showing up in git status (#492, #484)
- MCP server answers resources/list and prompts/list with empty lists instead
of -32601, clearing scary log lines in opencode/Codex (#621)
- index SAP HANA .xsjs/.xsjslib as JavaScript (#556) and TS .mts/.cts (#366)
- visit anonymous AMD/CommonJS/IIFE wrapper bodies so their inner functions and
calls are indexed instead of coming up empty (#528)
- batch the changed-file lookup so a huge first sync no longer hits
"too many SQL variables" (#540)
- list files with `git ls-files -z` so non-ASCII/CJK paths survive
core.quotepath and are no longer silently skipped (#541)
- attach Go methods on generic receivers (*T[P]) to their type (#583, RC1)
- impact no longer climbs the structural `contains` edge, so a leaf symbol
stops dragging in its sibling methods (#536)
- README: explicit `codegraph install` step, run in a new shell (#631)

The callback/observer synthesizers loaded every function and method node into
memory at once (getNodesByKind('function'/'method')) before scanning them down
to a tiny matched subset. On a symbol-dense project that array is gigabytes, so
indexing spiked the JS heap and aborted with "JavaScript heap out of memory".
Add QueryBuilder.iterateNodesByKind (a lazy node:sqlite cursor) and stream the
synthesizer scans instead of materializing them. Parsing and reference
resolution were already bounded; only the synthesis enumeration wasn't.
Measured on 80 files x 14k functions (~1.1M nodes): peak RSS 3717 MB -> 1318 MB,
no OOM. Full suite green; synthesized edges unchanged.

chokidar v4 holds one OS file descriptor per watched file on macOS (libuv's
kqueue backend registers an fd per vnode; fsevents is installed but v4 no
longer uses it). On a large project the `serve --mcp` daemon accumulated tens
of thousands of open REG descriptors and exhausted kern.maxfiles — crashing
unrelated processes system-wide with ENFILE. #276 only trimmed the count by
ignoring directories; the source tree still cost one fd per file.
Replace chokidar with a pure-JS native fs.watch hybrid, keeping codegraph's
zero-native-addon "any OS builds any bundle" invariant:
- macOS / Windows: a single recursive fs.watch (one FSEvents stream /
ReadDirectoryChangesW handle) -> O(1) descriptors regardless of repo size.
- Linux: one inotify watch per directory (O(dirs), dynamic add for new
dirs, capped via CODEGRAPH_MAX_DIR_WATCHES) instead of per-file watches.
Validated empirically: macOS 0 extra fds at 6k and 12k files; Linux 31 inotify
watches at 6k files (per-file would be 6k); Windows recursive catches nested
and new-directory edits. Full test suite green.
Tests drive the watcher through an inertForTests seam (no OS watcher) for
determinism under parallel vitest, with one real-fs end-to-end test exercising
the genuine native path.

Captures three development session checkpoints: per-symbol adaptive sizing (PR #569), trace relevance + cold-start fix (PR #580), and the explore-overhaul arc (explore as sole primary + Zustand store coverage + budget/render tuning). Documents root causes found, gotchas (stale-daemon foot-gun, Mac sleep corrupting benchmarks), validation methodology, and open threads for each session.
## 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.

The 0.9.x thin-installer turned @colbymchenry/codegraph into a bin-only
shim: require("@colbymchenry/codegraph") threw MODULE_NOT_FOUND and no
types shipped, breaking embedded library consumers (e.g. Electron apps)
upgrading from 0.8.0.
Restore programmatic use without re-bloating the thin shim or duplicating
the ~49 MB of grammars the per-platform bundle already carries:
- main -> npm-sdk.js re-exports the installed per-platform bundle's compiled
library (lib/dist/index.js) at runtime, reusing that bundle's own deps; it
falls back to a self-healed cache bundle, else throws an actionable error.
- types -> ship the .d.ts tree only (~590 KB) in the main package, built from
the same release so it can never skew from the runtime it re-exports.
- exports map resolves the `types` condition (nodenext) and the default entry.
- DatabaseConnection + QueryBuilder are now top-level exports, so embedded
callers get the building blocks from the package entry instead of deep
dist/ imports (which the shim no longer ships).
The CLI/MCP `bin` keeps execing the bundled Node; only library consumers run
on their own runtime, which must be Node 22.5+ for the built-in node:sqlite.
Validated end-to-end: built a real darwin-arm64 bundle, packed the npm
packages, installed them into a throwaway consumer, and confirmed require()
plus a full init/indexAll/searchNodes round-trip and the low-level
DatabaseConnection/QueryBuilder path all work on the host Node; types resolve
under both nodenext and classic node resolution; and the CLI shim still
launches. New hermetic tests cover npm-sdk resolution, cache fallback, and the
missing-bundle error.

Trace endpoint relevance (overloaded names resolve to the real implementation instead of an empty protocol/delegate stub), Swift closure-collection synthesizer, multi-phase god-file explore rendering, and serve --mcp cold-start handshake sped ~811ms→~90ms (proxy answers initialize/tools-list locally). Full suite green (1090 pass).
Sizes codegraph_explore to the answer, not the file count: shows the mechanism +
the exact methods you named in full (even buried in a large file) while collapsing
redundant interchangeable implementations to signatures. Adds uniqueness-aware
spare, per-symbol focused rendering of family files, all-tier test-file exclusion,
and named-method cluster survival in non-sibling god-files.
Validated A/B (Opus 4.8, 7-repo sweep): avg 25%% cheaper / 57%% fewer tokens / 23%%
faster / 62%% fewer tool calls. Django 9->23%% cheaper (0 reads), OkHttp 4->11%%
cheaper; gains across small/medium/large, inert repos unchanged.

codegraph_explore now skeletonizes off-spine, redundant members of a polymorphic
family (OkHttp's interceptor chain, Django's SQLCompiler family) to signatures
instead of shipping every full body, while keeping the dispatch mechanism, the
orchestrator/base, and any method the agent named in full. Sizes the response to
the answer rather than the budget cap, so interface-heavy flows stop costing more
than plain grep/read. Default on; CODEGRAPH_ADAPTIVE_EXPLORE=0 disables.
Gate: off-spine + >=3-impl sibling + not-spared, where spared = the agent named a
callable in the file UNLESS the file defines the family's supertype (a huge
base+subclasses file is Read-anyway, so skeletonizing frees explore budget).
Validated headless A/B (Opus 4.8): both former README cost outliers flipped —
OkHttp and Django went from costlier-than-native to cheaper; full 7-repo average
22%% cheaper / 47%% fewer tokens / 20%% faster / 50%% fewer tool calls, every repo
cost-positive, inert repos unchanged. 7-case regression test.

* fix(agent-eval): detect idle by content-stability, not spinner absence
Opus 4.8's extended-thinking TUI shows no spinner / interrupt hint / timer while it streams its final answer — those appear only during the thinking and tool-use phases. The old detector treated ~5s of not-busy + prompt-present as done, so it killed interactive runs mid-answer, silently truncating both arms of the tmux A/B (low tool counts; the final assistant message left as a mid-investigation preamble). Now a run is done only when the captured pane stops changing for ~8s; while streaming, the pane changes every poll so stability never accrues. BUSY_RE stays as the immediate busy-reset for the thinking/tool/live-timer phase. Content-stability is model-agnostic — it survives future spinner re-wordings.

Re-ran the VS Code A/B (headless median-of-4) on the current build and model. Cost savings held at 26% ($0.66->$0.89), but token/time/tool-call savings narrowed (78->63%, 52->20%, 85->69%) because Opus 4.8's without-CodeGraph arm explores far more efficiently than 4.7's did (16 tool calls vs 55, no Explore-subagent fan-out); the WITH arm is unchanged at 5 calls / 0 reads. Recomputed the average row and noted that the VS Code row is now a different model/version epoch than the other six.

* feat(resolution): synthesize gin middleware-chain edges (Next -> registered handlers)
Gin runs its entire handler chain through one dynamic line in (*Context).Next -- c.handlers[c.index](c), a slice-index dispatch tree-sitter can't resolve. So callees(Next) dead-ended at the len() helper and the flow ServeHTTP -> handleHTTPRequest -> Next stopped at the exact symbol a 'how does the middleware chain work' question is about, sending the agent to re-query and Read/grep (a measured gin WITH-arm rabbit-hole: 2/4 headless runs spiraled to ~5min, one mis-firing the opt-in Workflow orchestration tool). Find the chain dispatcher (a Go method invoking a handlers slice by index) and link it -> every HandlerFunc registered via .Use/.GET/.../.Handle, so callees(Next) and trace(ServeHTTP, handler) connect end-to-end. Gated on the dispatcher existing (inert on non-gin Go repos), named handlers only (inline closures skipped), capped; provenance heuristic / synthesizedBy gin-middleware-chain, registeredAt = the registration site. Validated: gin callees(Next) now surfaces Logger/Recovery/ErrorLogger + handlers (node count stable at 2,544; 5 precise edges); agent A/B (headless median-of-4, Opus 4.8) flipped gin from -58% cost / -129% time to +7% cost / +35% tokens / +8% time / 38% tool calls, all 4 WITH runs clean (0 Read/Grep/Bash). 167/167 unit tests pass incl. the new gin-middleware-chain test.

* docs(readme): publish uniform Opus 4.8 benchmark + per-repo breakdown accordion
Refresh all 7 benchmark rows to the v0.9.7 / Opus 4.8 headless median-of-4 (was a mix of the 4.8 VS Code row + six 4.7 rows). New average 18% cheaper / 51% fewer tokens / 16% faster / 57% fewer tool calls; headline + methodology note updated 4.7->4.8. The gap is smaller than the prior 4.7 numbers because Opus 4.8's native grep/read is more efficient (the without-arm no longer fans out into large Explore-subagent sweeps) -- not a codegraph regression; CodeGraph still cuts tool calls and tokens on all 7 repos, with cost marginal/negative only on django + okhttp. Adds a top-level 'Per-repo breakdown' accordion (per-metric Time/Reads/Grep-Bash/Tool calls/Tokens/Cost, WITH vs WITHOUT, per repo) directly below the condensed summary; methodology/queries/why-wins move to a second accordion.

`codegraph init` now runs the initial index automatically. The -i/--index
flag is kept but is now a no-op, accepted for backward compatibility so
existing muscle memory and scripts don't break. Addresses #483, where a user
asked why -i wasn't implicit.
README and site/ docs are intentionally NOT updated in this commit — they
describe the currently-released 0.9.7 behavior (where -i is still required).
Update them at the 0.9.8 release so users on 0.9.7 aren't misled.

A user asked what the `-i` flag does and why it isn't the default. Add a short
note under the Initialize Projects quickstart: plain `init` only scaffolds the
`.codegraph/` dir, `-i`/`--index` also runs the first index, and without it you
run `codegraph index` afterwards.

Completes #357. The no-symbol file-level class is yaml/twig/properties, but the
count fix only covered yaml/twig — so a .properties-only project still printed
"No files found to index" even though the files were stored. Introduce a single
isFileLevelOnlyLanguage predicate (the canonical set behind the tree-sitter
no-symbol branch, xml excluded since its MyBatis extractor emits a file node)
and use it at both count sites and the extraction dispatch so the list can't
drift. Adds .properties regression coverage for indexAll() and indexFiles().

The installer wrote a `## CodeGraph` usage block into each agent's
instructions file (CLAUDE.md / AGENTS.md / GEMINI.md / .cursor/rules /
Kiro steering) that duplicated, almost verbatim, the guidance the MCP
server already emits in its `initialize` response — so agents that
surface MCP instructions (Claude Code) read the same playbook twice
every turn.
All 6 instruction-writing targets (claude, cursor, codex, opencode,
gemini, kiro) now stop writing the block. install self-heals by
stripping a block a previous version wrote (uninstall already did), so
the next `codegraph install`/`uninstall` cleans up existing installs;
upgrading the package alone does not (the leftover block is harmless).
server-instructions.ts is now the single source of truth — the two
steers unique to the old template ("trust codegraph, don't re-verify
with grep" and the not-initialized -> `init -i` hint) are ported there.
Removes the now-dead INSTRUCTIONS_TEMPLATE / CLAUDE_MD_TEMPLATE,
claude-md-template.ts, writeClaudeMd / hasClaudeMdSection, and the
Cursor-only wireProjectSurfaces bootstrap. The install log learned a
"Removed" verb. Tests rewritten to the new contract + self-heal
coverage (140/140 installer tests pass).

On Windows, v0.9.5's detached shared daemon (#411) has no inherited console,
so any console-subsystem child it spawns gets a fresh visible console window
unless the spawn passes `windowsHide: true`. The fix adds the flag to all
ten `spawnSync` / `execFileSync` / `execSync` call sites across extraction,
sync, installer, and the WASM-flags relaunch. macOS/Linux ignore the option,
so this is a no-op elsewhere.
Fixes#485, #510, #530.
Co-authored work:
- #498 (csw-chen) — full sweep across extraction, sync, installer, and wasm-runtime. **This is the change being merged.**
- #505 (yushengruohui) — independently identified and fixed the 7 git execFileSync sites. Superseded by #498's broader sweep; same diagnosis.
- #521 (JirA44) — independently identified and fixed the WASM-runtime spawnSync re-exec. Superseded by #498's broader sweep; same diagnosis.
Validated on Windows 11 ARM64 (Parallels): a detached parent's 15 git spawns produce 15 visible black flash-windows without the fix and 0 with it.
* feat(go): generated-file down-rank + gRPC stub-impl bridge + trace-failure inlining
Multi-pronged fix to make codegraph competitive on Go multi-module repos
(cosmos-sdk, etcd) where it previously lost or tied. Driven by an 8-question
agent-eval audit across cobra, gin, prometheus, cosmos-sdk, and etcd: the
baseline had codegraph losing ~60% on cost on cosmos-sdk and mixed on etcd
deep cross-module flows, while winning cleanly on the single-module and
non-protobuf-heavy repos.
Diagnostics ruled OUT `go.work` parsing as the gap (prometheus crushes
without it). The actual failure modes were generated-file noise warping
disambiguation, missing gRPC interface→impl bridge in structural-typing Go,
and trace's failure path triggering 3-5 follow-up tool calls instead of
inlining the material the agent needed.
Changes:
- New `src/extraction/generated-detection.ts` — path-pattern classifier
for `.pb.go`, `.pulsar.go`, `_grpc.pb.go`, `_mock.go`, `_mocks.go`,
`mock_*.go`, `.generated.[jt]sx?`, `_pb2(_grpc)?.py`, `.pb.{cc,h}`,
`.g.dart`, `.freezed.dart`. Applied as a stable sort tiebreaker in
`findSymbol`, `findAllSymbols`, `codegraph_search` (MCP + CLI),
`codegraph_explore` file ranking, and context formatter Entry Points /
Related Symbols / Code blocks. Cosmos's `msgServer.Send` now ranks #3
instead of #9 on a `Send` search.
- New `goGrpcStubImplEdges` synthesizer in `callback-synthesizer.ts` —
detects `UnimplementedXxxServer` structs in generated files, identifies
their RPC methods (excluding `mustEmbed*` / `testEmbeddedByValue` gRPC
markers), and emits `calls` edges to the matching methods on any
non-generated struct whose method-name set is a superset. Closes Go's
structural-typing gap that the existing `interfaceOverrideEdges` (Java /
Kotlin only) couldn't bridge. 467 bridge edges on cosmos-sdk; bank's
`UnimplementedMsgServer::Send` points to `x/bank/keeper/msg_server.go`
only, not to `msgClient` siblings or mock files.
- Trace-failure rewrite (`handleTrace`) — when no static path connects
endpoints, instead of telling the agent to call `codegraph_node` (a
3-4-call fan-out), inline both endpoints' bodies (120 lines / 3600 chars
per endpoint), their callers (≤6), and callees (≤8) in one response.
- Trace endpoint-pairing improvements — scores every `from`×`to`
candidate combo by shared directory prefix and tries the best-paired
pair first (the full candidate set, not just FTS top-5). A
less-canonical-path penalty (`enterprise/`, `contrib/`, `examples/`,
`vendor/`, `third_party/`, `deprecated/`, `legacy/`) ensures the
canonical-module pair wins even when a side-experiment shares more of
its directory prefix. Find-path probe budget capped at 20 pairs.
- Test-file deprioritization in `codegraph_explore` `isLowValue` — adds
suffix patterns (`_test.go`, `_spec.rb`, `.test.ts`, `.spec.tsx`,
`Test.java`, `Spec.kt`) alongside the existing directory-style patterns.
Otherwise etcd's `watchable_store_test.go` consumes 5K chars of explore
budget that should go to the hand-written flow source.
Tests:
- New `__tests__/generated-detection.test.ts` (4 unit tests) pins the
suffix patterns.
- New "Go gRPC stub→impl synthesis" integration test suite in
`frameworks-integration.test.ts` (2 tests): positive bridge from stub
to hand-written impl, AND the precision case (don't bridge to a
generated sibling like `msgClient` in the same .pb.go).
- Full suite: 1076/1076 pass.
Empirical (post-fix, n=2 average per question):
| Repo / Q | WITH | WITHOUT | Reads (W/WO) | Time (W/WO)
|-------------------------|------------|-------------|--------------|------------
| cobra (parse cmds) | $0.27 | $0.27 | 0 / 4 | 39s / 60s
| prometheus (scrape→TSDB)| $0.63 | $0.70 | 0 / 6 | 106s/143s
| cosmos-sdk Q1 (MsgSend) | $0.41 | $0.26 | 1 / 2 | 67s / 64s
| cosmos-sdk Q2 (Delegate)| $0.47 | $0.46 | 0 / 5 | 50s / 73s
| cosmos-sdk Q3 (gov tally)| $0.34 | $0.31 | 1.5 / 3 | 54s / 76s
| etcd Q1 (Put→raft) | $0.65 | $0.78 | 0 / 4 | 98s / 129s
| etcd Q2 (watch) | $0.36 | $0.50 | 0 / 4+ | 58s / 89s
Codegraph wins on reads + time on every question. Cost is mixed: 3 clean
wins, 3 tied (within 10%), 1 stubborn cost loss on the grep-favored Q1.
Compared to baseline, the cosmos-sdk cost-gap collapsed from -60% to -15%
on average, and Q3 went from a 75% loss to a tie. Raw run artifacts in
`/tmp/cg-finalv2-*/` and `/tmp/cg-final-*/`.

* feat(mcp): auto-inline trace in codegraph_context for flow queries
When a codegraph_context task contains a flow keyword ("trace", "from",
"reach", "flow", "propagat", "how does", "how do") AND at least two
distinct PascalCase / camelCase identifiers, internally invoke trace
between the first two extracted symbols and splice the trace body into
the context response. Conservative trigger by design: false positives
waste one graph query; false negatives just fall back to the agent
calling trace itself (existing path-proximity wiring handles either
case).
Goal: collapse the agent's typical context → trace → explore sequence
into a single context call for clear flow queries, closing the
remaining cost-overhead gap on multi-call patterns. The path-proximity
+ less-canonical-path scoring + the trace-failure-inlined-bodies
behavior already let the inline trace land on the right endpoint pair
and return enough material that no follow-up codegraph_node/Read is
needed.
Doesn't fire on:
- cobra's "How does cobra parse commands and flags?" (no PascalCase
symbols) — verified in regression run, no behavior change ($0.260
WITH vs $0.257 WITHOUT, basically tied)
- queries where the agent doesn't call codegraph_context at all
(cosmos Q1 in the audit went search → trace → node → trace → node)
Tests: 1076/1076 still pass.

* feat(mcp): trace failure inlines TO file siblings to displace node fan-out
The cosmos-Q1 audit revealed a static-resolution gap: msgServer.Send's
*real* next hop is `k.Keeper.SendCoins` — an interface-method call on an
embedded field that tree-sitter can't resolve. The static getCallees list
for msgServer.Send is all utility/error functions (StringToBytes, Wrapf,
…). The actual flow (SendCoins → subUnlockedCoins → addCoins →
setBalance) lives entirely inside `x/bank/keeper/send.go`, which is also
where the TO endpoint (setBalance) lives.
When trace fails (no static path), inline the **top 5 functions/methods
in the destination file**, ordered by line-distance from the TO node.
This catches the flow that interface-method calls obscure — the
canonical "k.<Iface>.<Method>" pattern in Go, also relevant to Java
dependency-injection / Rails service-object dispatch / etc. where
interface dispatch hides the real call.
Conservative: only fires on trace FAILURE (no static path); the success
path is unchanged. Per-body cap (40 lines / 1200 chars), top 5 siblings.
Bookkeeps with `inlinedBodies` Set so endpoints already shown above
aren't duplicated.
Result: cosmos-Q1 — historically the most stubborn cost loss (-2.2× to
-39% across the audit) — flipped to a clean WIN: $0.257 WITH vs $0.449
WITHOUT (-43%), 34s vs 79s, 0 Reads vs 2 Reads + 5 Greps, 5 codegraph
calls vs 12. Regression-checked: prometheus, cobra, cosmos-Q2, etcd-Q1
all still WIN; Q3 is high-variance ($0.30-$0.45 range historically) and
fell within that on this run.

* feat: extend coverage to all supported languages, not just Go
PR review feedback: the audit was Go-driven, so the patterns I added
were Go-flavored. Extend each axis to every language CodeGraph
supports per the README, so the same improvements help Java / C# /
Python / TS / Swift / Dart projects too.
**generated-detection.ts** — Added patterns for:
- TS/JS: `.gen.[jt]sx?`, `.pb.[jt]s`, `_pb.[jt]s`, `_grpc_pb.[jt]s`
(ts-proto, gRPC-web, Apollo / GraphQL codegen, Hasura).
- Python: `_pb2.pyi` (mypy stubs from protobuf).
- C#: `.g.cs` (T4 / Razor codegen), `Grpc.cs` (protoc-gen-csharp).
- Java: `OuterClass.java` (protoc-gen-java), `Grpc.java`
(protoc-gen-grpc-java; this is where the `*ImplBase` abstract
class lives — same shape as the Go `Unimplemented*Server` stub).
- Swift: `.pb.swift` (protoc-gen-swift).
- Dart: `.pb.dart`, `.pbgrpc.dart`, `.chopper.dart`.
- Rust: `.generated.rs`.
**test-file deprioritization** (`isLowValue` in `codegraph_explore`)
— Added per-language conventions that the previous regex missed:
- Python: `test_*.py` (pytest discovery) and `*_test.py`.
- Ruby: `*_test.rb` (minitest) — `*_spec.rb` already covered.
- C#: `*Tests.cs`, `*Test.cs`, `*Spec.cs`.
- Swift: `*Tests.swift` (XCTest).
- Dart: `*_test.dart`.
**IFACE_OVERRIDE_LANGS** in `callback-synthesizer.ts`'s
`interfaceOverrideEdges` — extended from `java, kotlin` to
`java, kotlin, csharp, typescript, javascript, swift, scala`. Same
shape across these (nominal `implements`/`extends` on a class to an
interface/abstract base). Also iterates `struct` (Swift value types
conforming to a protocol) in addition to `class`. The existing
matchesSymbol-style logic and `getOutgoingEdges(..., ['implements',
'extends'])` work unchanged.
**CLAUDE.md** — Added a House rule: when the user references issues
or comments, anchor them to a date and version (last release vs.
last main commit vs. current branch tip) BEFORE concluding a fix is
incomplete. Issue #388 comments from May 25-27 were responding to
the released v0.9.5 / merged-PR-469 state — not to this branch's
in-flight work. The new rule walks through the disambiguation:
`grep -m1 '^## \[' CHANGELOG.md` for release version, `git log
--first-parent main -1` for main tip.

* feat(mcp): tiny-repo tool gating + shorter tool descriptions
Two cumulative changes targeting the small-repo cost gap surfaced by
the cross-language audit:
1. **Tool descriptions trimmed** (~2.1KB total saved across 10 tools).
The verbose marketing prose on codegraph_context / codegraph_node /
codegraph_explore / codegraph_trace / etc. wasn't moving the agent
toward better tool choices on top of the actual usage, but it was
adding ~525 tokens of cache-creation overhead to every question.
The trimmed descriptions keep the operational hints (e.g. "Query is
a bag of symbol/file names, not a question" for explore) but drop
the redundant prose.
2. **Dynamic tiny-repo tool gating** in `ToolHandler.getTools()`. On a
project with < 150 indexed files, the MCP server only exposes the
5 core tools (search, context, node, explore, trace) instead of all
10 — the omitted callers/callees/impact/status/files tools' use
cases on a sub-150-file repo reduce to one grep anyway. The MCP
tool-defs overhead is the #1 source of cost loss on tiny repos
(~$0.10-0.15 fixed cache-creation per question); cutting 5 tools
drops that by ~50%.
Effect on ky (~25 files, the worst pre-fix offender):
- Before: $0.59 WITH vs $0.42 WITHOUT (+42% loss, n=1)
- After: $0.32 WITH vs $0.44 WITHOUT (-26%, **flipped to WIN**)
Effect on cobra/sinatra/slim (50-80 files): still cost-loss, but
the gating doesn't regress them — same call-count, same reads.
The structural lower bound on those repos is what the agent's
grep+read path costs in absolute terms (~$0.20-0.30).
Non-breaking for medium+/large repos: all 10 tools remain exposed
when fileCount >= 150.
Tests: 1076/1076 still pass.

* feat(mcp): combined tiny-tier — smaller explore + tool gating (cobra/ky flip to WIN)
Combines the tool gating from the previous commit with a matching
explore-budget cut for projects under 150 files. The two together close
the cost gap that neither closes alone:
- Tool gating alone helped ky (WIN) but didn't move cobra/slim/sinatra
- Explore-budget cut alone helped slim slightly but regressed cobra
- COMBINED: cobra flips to WIN, ky stays a WIN, ky/cobra both clean
`getExploreOutputBudget(fileCount < 150)` returns:
maxOutputChars: 13000 (was 18000)
defaultMaxFiles: 4 (was 5)
gapThreshold: 7 (was 8)
maxSymbolsInFileHeader: 5 (was 6)
maxEdgesPerRelationshipKind: 4 (was 6)
includeRelationships: true (kept ON — cheap structural signal)
maxCharsPerFile: 3800 (unchanged — monotonic invariant w/ next tier)
This survives the cobra-regression-with-trim that the earlier
budget-only attempt suffered: with only 5 tools to choose from, the
agent doesn't fall back to extra codegraph_node calls when explore
returns less — there's no node call available.
Results on the four worst small-repo losses (combined intervention):
| Repo | Files | WITH (combo)| WITHOUT | Verdict (pre → post) |
|--------|-------|-------------|-------------|--------------------------|
| cobra | ~50 | $0.25 | $0.31 | loss → **WIN** (-19%) |
| ky | ~25 | $0.39 | $0.39 | -42% → tied |
| slim | ~80 | $0.31 | $0.24 | LOSS 31% → still LOSS |
| sinatra| ~60 | $0.30 | $0.23 | LOSS 18% → still LOSS |
sinatra/slim remain a cost-loss because their WITHOUT path is
structurally cheap (~$0.20 — fewer than 4 cheap grep+read calls).
Codegraph can't beat that absolute floor with any meaningful response.
Both still WIN on time + reads + tool-call count.
Tests: tier boundary cases updated to cover the new <150 / 150-499 /
500-4999 / 5000-14999 / >=15000 progression. Off-by-one guard updated
to include the new 149↔150 boundary. All 1076 tests pass.

* feat(context): trim maxNodes default to 8 on tiny repos
On a <150-file project the entire repo is grep-able in one turn, so the
20-node default `codegraph_context` was paying for a graph subset that
exceeds the agent's actual question. Cutting the tiny-repo default to 8
(typical 1-3 entry points + their immediate 1-hop neighbors) reduces
the context-tool response body without hitting sufficiency on the flow
shapes small repos actually contain.
Non-breaking: the agent can still pass an explicit `maxNodes` to
override; medium+ repos (>=150 files) keep the 20-node default.

n=2 audit on cobra/ky/sinatra ruled out cutting below 5 tools (search +
context + node + explore + trace) on the tiny-repo tier. The smaller
3-tool gate (search + context + trace) saved ~$0.025 of prompt overhead
but the agent fell back to extra Reads to cover what codegraph_node and
codegraph_explore would have answered — net cost regression on all three
test repos (cobra 17% → 48% loss, sinatra 18% → 96% loss). Documented

No behavior change beyond the comment: the 5-tool gate remains the

* docs(mcp): pin empirical lower bound on tool gating after n=2 micro test
Tested the hypothesis that exposing FEWER tools on micro repos (<50
files) would close the cost gap. Results:
- 1-tool gate (codegraph_search only):
- ky: +44% (worse than 5-tool +30%)
- express: +107% (catastrophic — was -43% WIN with all 10)
- cobra: +126% (way worse than 5-tool +17%)
The single-tool gate forces the agent to read everything because it
can't navigate the call graph. The 5 omitted tools (context, node,
explore, trace) were doing real work that grep+Read can't replicate.
Conclusion: 5 tools (search + context + node + explore + trace) is the
empirical lower bound on the tiny-repo tier. Cutting below regresses
EVERY tested repo. The remaining ~$0.04-0.08 of structural cost overhead
on tiny repos is unavoidable without sacrificing the value codegraph
provides at that scale (which would also make WITH = WITHOUT, defeating
the install).

* feat(mcp): iter3/iter4 — raise tool-gate to 500, sufficiency steering in context, hard-exclude low-value files
Three layered changes targeting the sinatra/slim/small-repo cost gap
that iter2's body-shrink failed to close (smaller bodies just pushed
the agent to Read instead):
1. **Tool-gate threshold 150 → 500** (`TINY_REPO_FILE_THRESHOLD`).
Sinatra (~159 files) and slim (~200 files) have the same structural
problem as cobra (
* feat(context): iter7 — core-directory boost to surface dominant-file siblings in search ranking
On projects with a single file holding the dense majority of internal
call edges (e.g. sinatra's `lib/sinatra/base.rb` at ~85% of in-file
edges), text search was favoring small focused extension files over the
core file. A small focused file like `multi_route.rb` wins on verbatim
name match + file-size normalization, burying the 1500-line core file's
longer method names (e.g. `route!` vs `route`).
Fix: detect the "dominant file" — the file whose in-file edge count is
≥3× the next candidate's — then add +25 to all results sharing its
directory prefix. This pulls the core file's siblings above
sibling-package extensions without hardcoding any repo structure.
`getDominantFile()` excludes test/spec files and generated files
(e.g. etcd's `rpc.pb.go` has 4× the in-file edges of `server.go` and
would otherwise hijack the boost toward generated protobuf stubs).
SQL pulls the top 20 candidates; path-pattern filtering handles what
SQLite LIKE can't express.
* feat(mcp): iter10+iter12 — routing manifest inline + probe-sweep harness
On small projects (<500 files) with a routing-shaped query, build a
URL→handler manifest directly from the graph (each `route` node joins to
its handler via `references`/`calls` edges) and inline the top handler
file's source. The agent gets the canonical routing answer in ONE
codegraph_context call — no need to parse framework DSL, Glob for
controllers, or chase down handler files.
The lever is "make the backend smarter so the agent doesn't have to":
- Parsing routes.rb / routes/api.php / urls.py DSL is the agent's job
in the WITHOUT arm. Codegraph already has it parsed as `route` nodes
with edges to handlers — we just project that to a manifest table.
- The handler implementations are right there in the index too; inline
the highest-handler-count file so the agent sees real code, not just
symbol names.
Results on the realworld template repos that were losing badly:
rails-rw +89% LOSS → -15% WIN (agent often answers with 0-1 tool calls)
laravel-rw +29% LOSS → +12% (tight gap)
gin-rw +30% LOSS → +23% (still loss but smaller)
flask-mb +64% LOSS → +25% (smaller gap)
The residual losses are mostly the agent's defensive read behavior on
super-cheap-WITHOUT repos (express-rw still does 4 Reads even with a
19-row manifest + service file inlined). That's an agent-side ceiling
the backend can't reach further without removing tools.
Also lands `scripts/agent-eval/probe-sweep.mjs` — a direct-MCP test
harness that runs context probes across 21 repos in ~600ms (vs ~30min
for a real claude audit). Enables rapid iteration on backend changes:
edit tools.ts / context-builder, npm run build, re-run probe-sweep,
compare signals (manifest fired? handler file inlined? response size?)
before paying for a claude run.

* fix(mcp): first tool call awaits catch-up sync (no stale rows for deleted files)
`MCPEngine.catchUpSync()` reconciles the index against the working tree
after open (catching `git pull`/`checkout`/`rebase` and any edits or
deletes made while no server was running). It was fire-and-forget — so a
tool call landing in the first ~50-300ms could race past it and serve
rows for files that no longer exist on disk. The per-file staleness
banner can't help here, because that signal is populated by the file
watcher (not by catch-up).
The fix: `catchUpSync()` now pushes its promise into `ToolHandler` via
`setCatchUpGate(p)`; the first `execute()` call awaits the gate and then
clears it. Subsequent calls pay nothing. Catch-up rejections are logged
by the engine and swallowed by the handler so a transient sync failure
never breaks tools.
Most visible on the "deleted everything between sessions" case, where
MCP previously returned stale rows pointing at non-existent files.
Validated end-to-end on a 10,640-file VS Code index: with the gate, a
codegraph_search for "ExtensionHost" against an empty (but stale-DB)
directory returns "No results found" after the catch-up drains the DB;
without the gate, the same call returns 10 stale hits.

Vitest already inherits process.env into every spawned `codegraph serve --mcp`
child, but on Node >= 25 the CLI's hard-block (src/bin/codegraph.ts) kills the
child before it can respond. Set CODEGRAPH_ALLOW_UNSAFE_NODE=1 via test.env so
the test suite is green regardless of the contributor's Node version; the
runtime guard itself is unchanged for end users.
Wrap top-level declarations of `.kt` / `.java` files in an implicit `namespace` node carrying the file's `package`, then resolve `import com.example.foo.Bar` through that qualifiedName index — so a Bar in Models.kt resolves correctly regardless of filename, a top-level function import binds to its declaration, Java↔Kotlin interop crosses cleanly, and same-name classes across packages no longer collide. Wildcard imports still go through name-matcher.
Also extracts Java/C# anonymous-class overrides (`new T() { ... }`) as first-class class nodes with their override methods. Phase 5.5 interface-impl then bridges T's abstract methods to the anonymous overrides automatically — including the lambda-returned `new T() { ... }` pattern common in guava (Splitter, CacheBuilder).
Concrete impact on macrozheng/mall (524 .java files, multi-module Spring + MyBatis): 524 namespace nodes, 862 imports edges newly resolve to Java symbols, 76 distinct `Criteria` classes preserved across packages with no merge. On google/guava (3,227 .java): 3,608 anonymous classes extracted, +2,534 interface-impl edges reach overrides hidden in `new T() { ... }` blocks.
Agent A/B playbook on small (spring-petclinic-kotlin, 38 .kt), medium (mall, 524 .java), large (guava, 3,227 .java) — 3 flow prompts × 2 runs/arm × 2 arms = 36 runs, claude-opus, headless. Spring repos: 0/0 Read/Grep with-arm, −27% wall-clock vs no-codegraph. Guava: 1.8 Read avg with-arm (vs 2.0 without) — improved by the anon-class extraction; residual is a lambda→SAM coverage gap orthogonal to FQN imports (filing follow-up).
The orchestrator's per-file counter only sees extraction-phase edges, so the `X nodes, Y edges` line printed after `codegraph init -i` / `codegraph index` undercounts the graph — often by more than half on repos with heavy cross-file resolution (mall: 20 047 reported vs 45 629 actually in the DB).
Snapshot (nodes, edges) before/after the full pipeline in `indexAll` and write the true delta back to the result. New lightweight `QueryBuilder.getNodeAndEdgeCount()` is one round-trip with no per-kind breakdowns. `indexFiles` (no resolution) and `sync` (uses `nodesUpdated`, not `nodesCreated`) are unaffected.
Regression test added: `__tests__/integration/full-pipeline.test.ts > reports edgesCreated including resolution + synthesizer phases`.

admin → bypasses the ruleset → push lands. Setup is one-time: create a
fine-grained PAT scoped to contents:write on this repo, add it as the
RELEASE_PAT secret. After that, future releases auto-promote cleanly.
Hidden the same way previously: 0.9.5's CHANGELOG was hand-promoted
before triggering Release, so the workflow's promote step short-
circuited on `git diff --quiet -- CHANGELOG.md` and never tried the
push. 0.9.5 also exposed the same bug in the lock-sync step — patched
manually after the fact in #440. 0.9.6 is the first release to actually
hit the bug.

* feat(resolution): add C/C++ include path resolution
Add full import resolution pipeline for C and C++ #include directives,
connecting extracted import nodes to actual header files in the project.
- Add C/C++ extension resolution (.h, .hpp, .hxx, .cpp, .cc, .cxx)
- Add system header filtering with ~80 C and ~80 C++ stdlib headers
- Add extractCppImports() for #include import mapping extraction
- Add compile_commands.json parsing for -I/-isystem include directories
- Add heuristic include dir discovery (include/, src/, lib/, api/)
- Add resolveCppIncludePath() for include directory search
- Add C/C++ built-in symbol filtering (printf, malloc, std::*, etc.)
- Wire getCppIncludeDirs into ResolutionContext
- Add 13 new tests for C/C++ import resolution and extraction

* review: wire #include resolution into pipeline + fix builtin filter
The PR landed the include-dir scan logic (loadCppIncludeDirs +
resolveCppIncludePath) but the indexer never reached it: imports
references with referenceName='X.h' fell into resolveViaImport's
symbol-lookup branch (matched extractCppImports' basename-without-ext
localName via .startsWith, then tried to find a symbol named like the
extension and failed). End result on bitcoin-core: 0 new file→file
imports vs main, despite the include-dir scan resolving paths correctly
when probed directly. resolveViaImport now has a C/C++ imports branch
that resolves the include path to the actual file node and returns
that — skipping the irrelevant symbol scan. Measured on bitcoin-core:
+2,059 newly resolved file→file imports (6,027 → 8,086, +34%).
The unconditional CPP_BUILT_INS / C_BUILT_INS filter also misfired:
C/C++ codebases routinely shadow stdlib names (bitcoin's mp::move,
custom allocators with free/malloc, stream classes with read/write/
close/open, logging libs wrapping printf). Filtering those names
killed legitimate edges — 1,179 → 0 for move(), 33 → 0 for free(),
149 → 7 for write() on bitcoin. The filter now defers to
hasAnyPossibleMatch: only filter when no user-defined symbol with the
name exists. std:: prefix stays unconditional (never user-shadowed in
practice). After: printf/free/open/close/read/write/swap all preserved
at main's counts; the std::move-binds-to-mp::move false-positives still
drop (correctly: −2,154 C/C++ calls).
Also: drop the duplicate 'FILE' in C_BUILT_INS; add an end-to-end test
that asserts `#include "X.h"` produces a file→file imports edge in the
real indexing pipeline (not just direct resolver probes); add a test
documenting the cross-language `.h` heuristic claim (Obj-C dirs are
intentionally allowed as C/C++ include dirs); add CHANGELOG entry
under [Unreleased] with measured numbers.

The variable / method-definition extractors never walked top-level
initializer values or inline-object method bodies, so calls like
`const token = getTokenMp()` and `methods: { save() { getTokenMp() } }`
showed up nowhere in `codegraph_callers`. The variable extractor now
walks any non-object initializer value; the method-definition extractor
still skips synthetic nodes for inline-object methods (noise rationale
unchanged) but now walks their bodies for calls. Surfaces in plain
`.ts`/`.js` files as well as Vue SFCs (`<script setup>` initializers +
Options API `methods: {...}` / `setup()`), which is where the bug was
originally reported.
Closes#425.
