* test: close resolution graphs before removing Windows fixtures
Close ArkTS and JVM graph connections in afterEach, including failed assertions. Verified both files on Windows 11 and macOS (32 tests).
* test: compare explore source lines across LF and CRLF checkouts
Normalize only line endings when matching emitted source against checked-out fixtures. Preserve the closure coverage and whole-line assertions. Both files pass on Windows 11 and macOS (15 tests).
* test: exercise old Git fallback without a POSIX shell shim
Inject only the unsupported ls-files invocation and run every other Git command against real repositories. Assert that each rejected call retries, use portable graph paths, and clean up fixtures. Passes on Windows 11 and macOS.
* test: normalize Python fixture before generating CRLF cases
The tests added in #2004 produced CRCRLF from a Windows checkout. Normalize the input to LF before constructing either variant. All 28 native and WASM cases pass on Windows 11 and macOS.
* test: allow time for eviction fixture indexes on Windows
The #2036 eviction test builds and reconciles nine real indexes and consistently exceeds its default five-second timeout on the VM. Allow 15 seconds for this test alone, preserving every assertion. The full file passes on Windows 11 and macOS (21 tests).
* test: finish MCP processes before resetting Windows fixtures
Launch actual servers with their runtime flags and await termination before directory removal. Use asynchronous removal retries for daemon fixtures. Establish a ready daemon and stop its first proxy before simulating PID reuse, then make source stale without opening a competing SQLite writer. Preserve lock and database byte-equality assertions. All touched files validated on Windows 11 and macOS.
* test: allow Windows named-pipe fallback polling to finish
The VM takes up to 25.7 seconds to complete the nominal six-second retry loop. Allow 30 seconds for the three fallback waits and 40 seconds for the two shorter enclosing tests, retaining their lock-preservation and read-only assertions. The full daemon file is validated on Windows 11 and macOS.
* fix(daemon): retry transient Windows PID-file sharing violations
A transient EPERM replacing daemon.pid aborted startup, observed in the quiet-client test and reproduced with a real locked handle at ba3c21e5. Retry only Windows sharing errors with five bounded delays, rechecking ownership each time and cleaning temporary files. Keep publication synchronous before client processing. Cover transient/permanent failures, changed ownership, non-retryable errors, and a real Windows handle; require a confirmed daemon round-trip before measuring a quiet session. Validated on Windows 11 and macOS.
* fix: safely stop daemon before reindex
* fix(index): coordinate rebuilds with running MCP daemons (#1325)
Stop verified project daemons and confirm termination before recreating SQLite.
Fence daemon and proxy reopening throughout rebuilds while preserving foreign and newer locks.
Add Windows lifecycle coverage and cross-platform shutdown regressions.

Cover watched, unwatched, and read-only engines blocking during a foreign rebuild and recovering after the fence is released.
* fix(mcp): answer a running index rebuild as guidance, not a tool error (#1325)
A projectPath call during `codegraph index` hit assertNoRebuild's plain Error
and returned isError; it is an expected, temporary condition, so it now uses a
RebuildInProgressError that the tool handler answers success-shaped.

A vitest pool worker is the one launch path that never received
`--liftoff-only`, so the suite compiled tree-sitter grammars on the
turboshaft tier. Once ~640 extraction tests have warmed a grammar function
up, its background tier-up job (Turboshaft LoopUnrollingPhase, symbolized
from the native stack) exhausts a compiler Zone and aborts the worker:
`Fatal process out of memory: Zone`, which vitest reports only as "Worker
exited unexpectedly" with the file's remaining tests unrun.
Pass WASM_RUNTIME_FLAGS through poolOptions.forks.execArgv, so the test
process matches the bundled launcher, the CLI re-exec and refresh-launcher.
V8 flags are process-global, so parse worker threads are covered too.
Linux x64, Node 24.15, `__tests__/extraction.test.ts` (655 tests):
without the flag 3 of 4 runs died at the same test (639 passed);
with it 2 of 2 passed, in 19–24s instead of 34–41s. Neither
`--no-wasm-loop-unrolling` nor `--no-wasm-dynamic-tiering` prevents it.

The live-holder case wrote `pid: 1` and leaned on its own comment, "On Linux,
PID 1 is almost always alive". Windows has no PID 1, so tryAcquireWriterLock
read the holder as dead and acquired — the correct behaviour for a dead
holder, and a failing assertion. The platform-specific part was the fixture,
not the lock.
A parked child process is alive on every platform, and not stealing from a
live holder is what the lock actually promises, so the case now tests the
promise rather than a number that happens to name a running process. The child
is reaped in afterEach.
Fixes#1752.

Bisect identifies 5eaa6fed (#2034, #1820) as the first bad commit: its Python named-import fallback resolves task.delay() to the task function itself, hiding the queue effect in API steps. Require member resolution before returning a named Python import's target for attribute access.
Keep direct calls, callbacks, constructors, and known members working. Add absolute/relative aliased-import regression coverage without changing the existing steps assertions.
Validation: git bisect with preserved steps test, tsc and copy-assets at every step, CODEGRAPH_KERNEL=0 throughout bisect. 338 tests pass across ui-steps-api-servers, function-ref, rebuilt kernel-tsjs-parity, resolution, and ui-effects. Issue #1820 repro and tsc --noEmit pass.
Node runs a setTimeout delay above 2^31-1 ms after 1 ms instead, so a huge
CODEGRAPH_WATCHDOG_TIMEOUT_MS SIGKILLed a healthy server at once and a huge
CODEGRAPH_STARTUP_HANDSHAKE_TIMEOUT_MS abandoned the launch within
milliseconds. Both parsers now cap at 2147483647.

* fix(mcp): keep an explicit projectPath project in sync (#1835)
A project opened through a tool call's `projectPath` (a repository other
than the server's default — e.g. an indexed child of an un-indexed
workspace) was opened read-only: no catch-up sync on open and no file
watcher, so its answers went stale until someone ran `codegraph sync`.
The engine now owns the lifecycle of every project the ToolHandler opens
for an explicit path, mirroring the default project:
- the project's writer lock is acquired (#1740 single-writer rule); if
another live process holds it, that process keeps syncing and we only
read;
- a catch-up `sync()` runs on open and the first call against that
project awaits it, time-boxed like the default gate (#905);
- a file watcher runs for as long as the project stays cached.
Bounds: the cache is keyed by the canonical (realpath) root, so a
symlinked spelling shares one connection and one watcher; it is LRU with
`MAX_CACHED_PROJECTS = 8` — opening a ninth closes the least recently
used (watcher stopped, writer lock released, DB closed); `stop()` closes
them all. Un-indexed paths still get the success-shaped guidance.

* fix(cpp): macro invocations are not calls; local objects call their constructor
A function-like macro invocation (`TRACE_POINT(1)`) parses as a call, and
the resolver bound it to a same-named free function in another translation
unit — a caller and a callee that never existed (#1838). And local object
initialization (`Widget w;` / `Widget w(1);` / `Widget w{1};`) reached the
class node instead of a constructor, or nothing at all for the default
form (#1839).
Extraction (wasm walker and the Rust kernel, in parity):
- every `preproc_function_def` becomes a `constant` node whose signature
is the directive, so the index knows which names are macros;
- a C++ declaration emits one `calls` ref per constructed object, shaped
`ns::T::T/<arity>`; pointer, reference and function declarators,
`extern`, and array element braces construct nothing; the #1035
`instantiates` ref is unchanged;
- constructors carry their parameter list as the signature.
Resolution:
- `cpp-macro-visibility.ts` walks the translation unit (root file plus
in-repo includes, each file once) over per-file summaries of
function-like defines, undefs and includes, evaluating what each file
can decide itself (literals, its own defines, the include-guard idiom).
A call whose name is definitely a macro at that point, or a name that
only macros bear, resolves to nothing. A macro that exists in one build
configuration only (CMSIS's `__DSB()` under the ARM compilers, a
target's HAL compat header) keeps the call to the function the other
configuration compiles; a wrapper macro that calls its own name is how
that function gets called and hides nothing.
- `cpp-constructor.ts` resolves the constructor refs: the type in the
lexical namespaces of the call site, then the single overload whose
parameter count admits the arguments; two admitting overloads, an
initializer_list overload, or an aggregate yield no edge.
- a `#define` constant is never a `calls` target and does not count
toward the same-name ceiling.
Measured on a betaflight tree (4,017 files, wasm arm): 153 `calls` edges
lost — all fabricated (`MIN`/`MAX` bound to a CLI enum member, macros
misparsed as functions, a cross-vendor `SWAPBYTE`) — and 34 constructor
edges gained; indexing 34s vs 30s.

* fix(extraction): record callers for methods passed as values (#1820)
pool.submit(obj.method), thread_pool_exec(self.store.fetch), and Go
Submit(c.store.Fetch) produced no callers/impact edge because only
obj.method(...) call expressions were captured. Member values are now
emitted as *.method function-refs and resolve unique-or-drop
(same-file first). Two methods of the same name still produce no edge.
Go go c.store.Fetch(ids) remains a calls edge (it is a call expression).
EXTRACTION_VERSION 27: MCP daemon catch-up rebuilds a stale index on
start so the watcher does not keep serving the hole after upgrade.
* fix(resolution): do not let test mocks veto #1820 method-value callers
A unique production method plus a unit-test double of the same name
was treated as ambiguous, so retrieve_vision_vectors still looked
callback-invisible on a real repo. Prefer the non-test file when
exactly one production target remains.
* fix(resolution): prefer a real override over a NotImplementedError base
#1820 unique-or-drop treated DocStoreConnection.delete_payload_fields
(the ABC stub) and QdrantConnection.delete_payload_fields as ambiguous,
so gc_stale_member_stamps stayed invisible. Skip short not-implemented
stubs when exactly one real implementation remains.

Python attributes and Go selectors used as callback values were dropped or reduced to bare method names.

* fix(resolution): stop expression-receiver calls from binding to unrelated methods
A method called on an expression receiver reached the resolver as the bare
method name, and exact-match bound it to any project method of that name:
`(await list()).map(...)` in TypeScript onto a UI adapter class's `map`
(0.9), and `v.iter().map(...)` in Rust onto the same TypeScript method
across languages (0.5).
TS/JS extraction (mirrored in the kernel): look through receiver wrappers
that keep the same object — parentheses, `!`, `as`/`satisfies`, `<T>x`,
`await` (including the grammar's `(a && b)!` parse of `a && b!`) — so
`x!.m()` is `x.m` and `(await f()).m()` is `f().m`; any other receiver with
no static type (`(a ?? b).m()`, `f().list.m()`, `arr[0].m()`) emits nothing
instead of the bare name. `this`/`super` (and chains rooted at them),
`window.*` chains and `new C().m()` keep their existing bare form.
Resolution: a bare-named call may cross a language family only through the
C ABI (a C/C++ symbol, or a free function a C/Objective-C/Swift caller
reaches, e.g. a cgo `//export`). A class member of another family, or a
function/class/variable outside that pair, is rejected as the candidate a
strategy commits to (exact-match single/best and fuzzy), never filtered out
of the pool, so no lone survivor is manufactured.

* fix(resolution): resolve same-file calls through object-literal aliases (#1932)
`api.getUser()` where `api` is `const api = { getUser }` (or
`{ getUser: fetchUser }`) and the function is declared outside the literal
resolved to nothing in the literal's own file: the #1573 containment lookup
only finds members defined inside the literal, and the binding-following
alias path existed only on the import side, so same-file callers were
missing from callers / impact / blast radius.
- Extract the member-binding read into `objectLiteralMemberBinding`, which
splits the literal into its own top-level members on comment- and
string-blanked source, so a nested object, a member body, a comment or a
string never donates a binding, and `{ fn: 1 }` names nothing. The import
path now uses it too.
- In the same-file object-literal receiver strategy, fall back to that
binding: a symbol of the file, else one of its imports, skipped when a
parameter or nested declaration shadows the name where the literal is
written.
Resolution-only change; extraction output (and kernel parity) unchanged.

* fix(scala): resolve extends/with to the trait, not its companion object
The Scala trait + companion object idiom puts two same-named symbols in
one file. Both were indexed as kind 'class', so an 'extends X' reference
tied between the trait and its companion and the winner was arbitrary.
When the companion won, every subtype was detached from the trait's
inheritance chain, and impact analysis on a widely-used trait stopped at
depth 1.
- classify Scala object_definition as 'module' (a singleton value, not a
type - 'extends' can never target it)
- add 'module' to the classifyClassNode contract and handle it in the
extractor dispatch
- in name matching, bias extends/implements references toward actual
type definitions and penalize 'module' candidates, so the trait wins
the tie deterministically
Regression test: trait + companion in one file, subclass in another -
the extends edge must land on the trait and impact must reach the
subtype through it.
* fix(scala): resolve companion inheritance to type definitions (#1824)
Scala objects and their companion types could tie during inheritance resolution, disconnecting subtype impact paths.

* fix(resolution): resolve this.#field.method() on the field's type (#1987)
A call through an ES private field fell outside the `this.<field>` shape
(#1496): the extractor accepted only a property_identifier, so
`this.#items.add(x)` was emitted as the bare `add` and exact-matched
whichever project method shared the name, often the calling method itself.
The extractor and its kernel mirror now keep `this.#items.add`, and the
resolver matches that shape and reads the field's type off the class
declaration. The field regexes open with a lookbehind instead of `\b`,
which never matches before `#`. A builtin or external field type
(`new Set()`, a `Map`, an array) now yields no edge.

call; in-process dispatch no longer depends on it (restores the oversized-output
truncation test).

* fix(watcher): auto-sync changes inside symlinked directories (#770)
The file watcher (Linux inotify strategy) did not follow directory
symlinks when building its watch set, so a project dir symlinked into
the workspace root was silently invisible to the watcher.
Changes:
1. watcher.ts: watchTree() now detects isSymbolicLink() entries,
resolves real targets with realpathSync(), and recursively watches
directory symlinks. Guards against cycles with a visitedRealDirs Set
— tracking regular dirs too so a symlink→already-visited-path is
also detected. Mirrors the indexer's walk() in extraction/index.ts.
2. utils.ts: Added allowSymlinkedDirs parameter to validatePathWithinRoot().
When true, skips the realpath check that would reject watched symlinks
whose targets live outside the lexical project root. All internal
sync/index paths pass true here; user-facing paths (MCP layer) keep
the existing strict validation.
3. extraction/index.ts: All internal sync/index paths now pass
allowSymlinkedDirs: true so the watcher can read files from
symlinked directories.
4. __tests__/watcher.test.ts: Added integration test for symlinked
directory auto-sync, plus a symlink-cycle detection test.

* test(mcp): reap the daemon-mode writer so the temp project can be removed
In daemon mode the writer is a third process spawned by the proxies and never recorded in children -- the test asserts its pid is neither child's. Killing only the proxies left it holding the index, so fs.rmSync failed and its catch swallowed the error: one temp directory and one live serve --mcp process leaked per run while both tests passed.
writer.pid already names the daemon and the test already parses it, so afterEach now reads it before killing the proxies and signals the writer too. The removal is no longer silenced, because the swallowed error is what made this invisible.
Measured on Windows 11 with TEMP redirected to a private directory: before, 1 leaked directory and 1 surviving process per run; after, 0 and 0, both tests still passing. Fixes#1782.
* fix(mcp): reap writer-lock test daemon and verify cleanup (#1782)
The writer-lock test stopped its proxies but left their daemon running, hiding directory removal failures.
Preserve the contributor fix and add verified daemon shutdown, bounded exit polling, and cleanup assertions.
Ensure the daemon test overrides inherited direct-mode configuration.

* test: build dist/ before the suite when it is missing or stale (#1879)
About thirty suites spawn dist/bin/codegraph.js, the parallel resolver loads
its worker from dist/, and the `codegraph ui` suites serve dist/viewer/. On a
fresh checkout `npm ci && npm test` failed them on spawn timeouts and a
missing-viewer error that never mentioned the build; after an edit without a
rebuild they quietly exercised the old code.
A Vitest globalSetup now rebuilds each half only when it is missing or older
than its sources: `tsc` + copy-assets when anything under src/ is newer than
dist/bin/codegraph.js, `build:ui` when ui/src/ is newer than
dist/viewer/index.html. A current dist/ costs one mtime walk.

* fix(mcp): share one connection across two spellings of one root (#1057)
A symlinked checkout, or a case-variant of a root on a case-insensitive
mount (macOS, NTFS, WSL DrvFs), resolved to two path strings and opened two
connections to the same .codegraph/codegraph.db.
The connection cache stays keyed by path, so a root recreated at the same
path still heals in place (#925). On a miss, an open root that is the same
index NOW (both data directories stat to one dev:ino, read as bigints) is
reused and the new spelling filed as its alias. Comparing live identities
means a deleted root never matches, even if a new directory reuses its
inode. Windows has no usable inode, so it compares the case-folded
realpath.native instead. statInode moves to directory.ts so the DB layer
and the cache share one reading, and closeAll closes an aliased instance
once.
* fix(mcp): keep root aliases out of the connection cache (#1057)
A second spelling of an open root was filed in projectCache under its own key,
so one CodeGraph sat under two keys. Anything that drops one key and closes its
connection (a bounded cache's eviction, as proposed in #1929) then left the
other key holding a closed handle: every query on that spelling, and through
the alias scan on the original spelling too, failed with "database is not
open" until restart.
Aliases now live in their own map (spelling -> projectCache key). projectCache
is back to one key per instance, and an alias whose entry is gone is dropped
and re-resolved instead of served.
* fix(mcp): deduplicate equivalent project paths (#1057)
Equivalent project paths could open duplicate cached connections.
Compare current filesystem identities using bigint inodes and native Windows paths.
Revalidate aliases and pin cached connection owners to symlink targets.
Preserve recreation recovery and single-owner cleanup.

* fix(installer): resolve Antigravity codegraph command out of fnm's ephemeral per-shell dir
- resolveCodegraphCommand resolved `command -v codegraph`, which under fnm returns an ephemeral ~/.local/state/fnm_multishells/<pid>/bin path that fnm removes when the installing shell exits, leaving a dangling MCP command
- realpath the containing directory so the written command survives shell exit
- preserve the `codegraph` basename so agents that validate the command by basename still match
- fall back to the raw resolved path if realpath fails
* fix(installer): preserve Antigravity command after fnm shell exit (#1443)
Antigravity saved an ephemeral fnm shell path that disappeared after shell exit.
Canonicalize the containing directory while preserving the codegraph basename and existing fallbacks.
Add macOS regression coverage for symlink removal, stable paths, and lookup failures.

* fix(dead-code): treat an ancestor outside the index as opaque (#1973)
An override is excluded from the dead-code report when its ancestor is in
the graph, or is present but declares no members we can read. An ancestor
outside the project (React.Component, stream.Transform, a NestJS
interface) creates no edge at all, so a lifecycle method the framework
calls looked like it overrode nothing and was listed as unreferenced.
The resolver does record such an ancestor, as a failed extends /
implements row. A container with one, or a project ancestor of one that
has it, now counts as having an opaque ancestor, and its members are
excluded under "overriding".

* feat(extraction): index Python docstrings, not just preceding comments (#1905)
getPrecedingDocstring only walks preceding comment siblings, so a Python
docstring — a bare string literal first in the body — never reached the
docstring column, never entered nodes_fts, and was never shown by
`codegraph node`. The identical sentence written as a leading `#` comment was
both. For a Python codebase that is most of the prose there is. (#1905)
Adds an optional getBodyDocstring() to LanguageExtractor, in the same shape as
getSignature(), and routes every docstring call site through one docstringFor()
helper that consults both sources. A node carrying a comment AND a docstring
keeps both, joined: they are two things the author wrote about the same symbol
and the column is free text.
The Python implementation reads the grammar`s string_content rather than
slicing quotes off the raw text, so r/u/b prefixes and both triple-quote forms
work without a regex per case; f-strings are skipped because an interpolated
string is code, not prose. Dedent follows PEP 257 (first line exempt).
Scoped to Python deliberately. Julia (a string sibling before the def) and
Elixir (@doc) fit the same hook and are left as follow-ups.
* fix(extraction): index Python body docstrings across backends (#1905)
Python extraction only consulted preceding comments, leaving body docstrings absent from search and rendered prose.
Extend the contributor's hook to module and definition docstrings, and mirror it in the native kernel.
Handle comments, concatenated literals, and indentation consistently while rejecting bytes, f-strings, and tuples.
Verify persistence, exact-name ranking, MCP/CLI rendering, and native/WASM parity.
