* fix(lbug): serialize singleton connection to stop --pdg analyze double-free
LadybugDB is single-writer and its Connection is NOT safe for concurrent
query execution. The WAL-checkpoint driver (5s setInterval) issued
`conn.query('CHECKPOINT')` on the same module-singleton `conn` the analyze
pipeline used for COPY. With --pdg the extra BasicBlock / REACHING_DEF / CDG /
POST_DOMINATE / TAINTED / CALL_SUMMARY / TAINT_PATH table COPYs outlast the
5s tick, so a checkpoint executed concurrently with an in-flight COPY on one
connection -> two libuv workers mutate shared native state -> heap corruption
("double free or corruption (out)" / SIGABRT, detected at the final
"Saving metadata..." free).
Fix: add conn-lock.ts (`withConnLock`, a promise-chain mutex) and run every
singleton-`conn` helper's full query + result-drain inside it: queryAndDrain
(when targetConn === conn), executePrepared, executeWithReusedStatement,
flushWAL, tryFlushWAL, getLbugStats, deleteAllInterprocTaintPaths,
deleteAllCallSummaries. Add an `if (inflight) return` reentrancy guard to the
driver tick so overdue ticks don't stack checkpoints. streamQuery is
intentionally NOT wrapped (read path, re-entrant per-row callback).
Reproduced the crash with concurrent queries on one raw Connection (serial =
stable); verified the fix drives the same overlap through the locked adapter
without crashing.
Tests: conn-lock serialization (no overlap / FIFO / throw-releases) and
driver reentrancy guard.

* fix(lbug): lock deleteAllCommunitiesAndProcesses against the WAL driver (#2264)
The count + DETACH DELETE ran raw conn.query on the singleton connection during
incremental --pdg writeback while the WAL-checkpoint driver was live — the same
concurrent CHECKPOINT-vs-write double-free this branch fixes elsewhere. Wrap the
body in withConnLock, mirroring the already-wrapped deleteAllInterprocTaintPaths.
Adds test/integration/lbug-conn-serialization.test.ts (call-through withConnLock
spy) asserting the helper now acquires the lock, wired into the lbug-db vitest
project (and excluded from the default project so it doesn't run twice).

* fix(lbug): lock queryImporters against the WAL driver (#2264)
queryImporters issued a raw conn.query on the singleton connection inside the
importer-BFS loop of incremental --pdg writeback, while the WAL-checkpoint driver
could fire a concurrent CHECKPOINT — the same double-free class. Wrap the read
(query + getAll + drain) in withConnLock.

* fix(lbug): lock deleteNodesForFile count query on the singleton path (#2264)
The per-table count read used a raw targetConn.query while the sibling DETACH
DELETE already routed through the locked queryAndDrain — an asymmetry that left
the count racing the WAL-checkpoint driver during incremental --pdg writeback.
Gate the count through withConnLock when targetConn === conn (the singleton),
matching queryAndDrain; per-query/temp connections stay lock-free.
Test asserts the count loop takes the lock once per filePath-bearing node table.

* fix(lbug): drain DELETE results in the deleteAll* helpers (#2264)
deleteAllInterprocTaintPaths, deleteAllCallSummaries, and
deleteAllCommunitiesAndProcesses awaited conn.query(...DELETE...) but dropped the
returned QueryResult (only the count result was closed), leaking a native result
handle and violating the helpers' own "query + drain inside the lock" contract.
Close each delete result via closeQueryResults, matching the count handling.
Adds a seeded drain test (closeQueryResults fires for the DELETE result).

* fix(lbug): make the conn-lock non-reentrancy invariant enforced, not just documented (#2264)
A future withConnLock-wrapped helper calling another wrapped helper would await
its own holder's tail and hang silently. Add an AsyncLocalStorage-based re-entry
guard: withConnLock throws a clear error when invoked from within a holding fn's
async context. A boolean flag can't do this — a legitimately-queued top-level
caller also runs while the lock is held; only AsyncLocalStorage distinguishes a
true nested call from normal contention.
Tests: re-entry throws (not deadlocks); sequential and concurrent top-level calls
do NOT false-fire; the lock releases after a re-entry throw.

* test(lbug): fix stale CHECKPOINT guard regex after the c.query refactor (#2264)
lbug-checkpoint.test.ts asserted exactly two CHECKPOINT sites by grepping the
literal `conn.query('CHECKPOINT')`. The connection-serialization refactor changed
flushWAL/tryFlushWAL to capture `const c = conn` and call `c.query('CHECKPOINT')`
inside withConnLock, so the literal grep found 0 and the test failed (expected 2).
Make the regex receiver-agnostic (`.query('CHECKPOINT')`) — preserves the guard's
intent (exactly two authorized CHECKPOINT sites; a third is a regression) while
tolerating the captured-receiver form.

* fix(lbug): skip native close on CLI exit to dodge LadybugDB destructor double-free (#2264)
THE actual fix for the `analyze --pdg` crash. gdb shows the abort is a double-free
inside LadybugDB's own destructor during conn.close():
"double free or corruption (out)" -> abort
lbug::main::ClientContext::~ClientContext()
lbug::main::Connection::~Connection()
NodeConnection::Close(...) <- conn.close() from safeClose
It reproduces with the WAL driver OFF and with serial load, so it is NOT the
checkpoint/COPY concurrency the rest of this branch serialized — it's a native
LadybugDB engine bug (@ladybugdb/core 0.17.1, latest stable) triggered by the
larger --pdg write set, firing during teardown AFTER a fully-written, checkpointed
index.
Fix: closeLbug({ skipNativeClose }) CHECKPOINTs for durability (flushWAL) then
skips conn.close()/db.close(), leaving the handles referenced so no GC finalizer
re-runs the destructor. The CLI analyze command (success, error, and SIGINT paths
all process.exit) opts in via skipNativeCloseOnExit; long-lived callers (MCP
server, tests) keep the real close. Mirrors the pool adapter's fire-and-forget
native close and the ONNX native-cleanup philosophy.
Validated end-to-end: `analyze --pdg --force` now exits 0 with a 193,876-node
index; re-opening it (no --force) reads clean and reports up-to-date, proving the
CHECKPOINT-only persistence is durable without db.close().
Workaround for an upstream LadybugDB bug (ClientContext destructor double-free).

* fix(lbug): keep conn.close()/db.close() literals out of the closeLbug comment (#2264 review P1-1)
The skipNativeClose comment in closeLbug contained the literal `conn.close()`/
`db.close()`, which the structural guard test (lbug-checkpoint.test.ts:52-53 —
"closeLbug must not inline conn.close()/db.close()") greps for and fails on.
Reword the comment to describe the native close without the literal tokens; the
code already delegates close exclusively to safeClose, so the guard's intent holds.

* fix(lbug): real close on the analyze error path to avoid a hang under skipNativeClose (#2264 review P1-2)
The CLI error handler soft-returns (process.exitCode = 1) instead of forcing
exit, relying on the released native handles to let Node terminate. The earlier
commit made runFullAnalysis's error-path closeLbug skip the native close, leaving
live LadybugDB handles that keep the event loop alive forever — a post-init
analyze failure would hang. Only the SUCCESS path (which guarantees a following
process.exit) skips the native close; the error path now always closes for real.
A late-error close could still abort in the destructor, but that terminates the
process — it does not hang.

* fix(server): skip native close in the analyze worker to avoid the LadybugDB destructor crash (#2264 review P2-3)
The forked server analyze worker runs runFullAnalysis then force-exits
(process.exit(0)). With a real native close inside runFullAnalysis, the LadybugDB
ClientContext destructor can double-free after --pdg writes and abort the worker
BEFORE it sends 'complete', failing the parent's analyze. Pass
skipNativeCloseOnExit: true so the worker checkpoints for durability and lets its
process.exit reclaim the handles — same about-to-exit contract as the CLI.

* fix(cli): force exit on a soft error-return when LadybugDB handles are open (#2264 review P1)
The full-analysis success path skip-closes LadybugDB (handles left open, reclaimed
by process.exit). If a post-finalize step (assertAnalysisFinalized) then throws,
the outer catch soft-returns (process.exitCode = 1) — and with native handles
open the event loop never drains, so the process HANGS instead of exiting 1.
Guard once at the analyzeCommand wrapper, after the try/finally: if isLbugReady()
(handles still open) the analyze actually ran and we must force the exit. The
success path never reaches here (analyzeCommandImpl process.exit(0)s itself);
early-validation errors and unit tests that mock runFullAnalysis never open the DB
(isLbugReady() false), so the soft return is preserved.
Adds analyze-finalize-failure-exits.test.ts (force-exits when handles open; does
NOT when they aren't). The analyze-*.test.ts that mock lbug-adapter now also mock
isLbugReady (vitest throws on accessing an undefined export of a mocked module).

* fix(lbug): skip the native close on the analyze error path too (#2264 review P2)
A real conn.close() on the error path after large --pdg writes can itself hit the
LadybugDB ClientContext destructor double-free → SIGABRT, degrading an actionable
exit-1 error into a raw native abort. Switch the error-path close to
skipNativeClose (mirroring the success path). Safe now that the CLI catch
force-exits when isLbugReady() (the prior commit): handles left open are reclaimed
by that guaranteed process.exit, so the process terminates without the abort and
without hanging. flushWAL keeps the partial index durable.
Depends on the prior commit (CLI force-exit guard).

read; no nested wrapped helpers.

comment wording — a prior commit had to reword a comment just to keep it green.

in safeClose) is preserved and no longer breaks on a comment edit.

The relationship COPY passed the module-level `conn` to copyCsvWithRetry while the
node COPY uses the captured `writeConn`. Use `writeConn` for both — one captured
reference for the whole bulk load, removing the latent identity dependency. Same
object during analyze (`conn` is only reassigned at open/close under the session
lock), so the queryAndDrain `targetConn === conn` lock gate still engages.

* fix(server): make the analyze worker's IPC send() failure-safe (#2264 review P3)
The worker's send() used `process.send?.(msg)` — the `?.` guards an undefined
channel but not a throw from an already-closed one (ERR_IPC_CHANNEL_CLOSED). A
throw in the catch-branch send() would escape the message handler and skip the
scheduled `setTimeout(process.exit(0))`, stranding the worker (with skip-close
leaving native handles open, #2264). Wrap process.send in try/catch so the exit
always fires; a vanished child is a failure to the parent regardless.
Not unit-tested: send() is module-private and importing the worker registers
process signal handlers; the change is a defensive try/catch around one call.

* fix(server): report analyze-worker errors over IPC, never swallow (#2264 P3)
The worker's send() swallowed IPC failures (and a prior pass logged them to
stderr). Per review, all worker errors must be reported back to the parent over
the existing IPC channel (send({ type: 'error' })) and nothing silently dropped.
- send() no longer catches: a dead channel (ERR_IPC_CHANNEL_CLOSED) throws
instead of being swallowed.
- Every handler (uncaughtException, unhandledRejection, SIGTERM, the analysis
message handler) reports its error via send() in try and schedules process.exit
in finally, so a throw from send() can no longer skip the exit and wedge the
worker — the P3 'schedule the exit so it always fires' fix, without a swallow.
- SIGTERM cleanup failures are now reported to the parent instead of an empty
catch {}.

* fix(workers): report every caught parse-worker error over IPC (#2264)
The parse worker swallowed or only-locally-logged several caught errors, so they
never reached the pool: the per-language-group catch was an empty catch {} that
silently dropped the whole group on any throw (not just an unavailable grammar),
the per-file parse/query-execution catches only logger.warn'd (worker-thread
local), and the C++ template-constraint catch swallowed silently.
Route all work-path catches through a new reportWarning() helper that posts
{ type: 'warning', message } to the pool (which logs it on the main thread AND
resets the worker idle timer, so a worker grinding through failing files isn't
falsely idle-evicted), with a logger.warn fallback for the non-worker path. The
existing inline warning sites (query-compilation, the extractParsedFile callback,
CFG build) are migrated to the same helper.
The 4 optional-grammar module-load guards (Swift/Dart/Kotlin/C) stay silent: they
run before the 'ready' handshake and their absence is already surfaced via
result.skippedLanguages + the isLanguageAvailable gate. Fatal/group-aborting
errors continue to flow through the message handler's { type: 'error', errorStack }.

* test(cli): harden finalize-failure test against forked-worker death (#2264)
analyzeCommand calls installFatalHandlers(), which registers global
unhandledRejection/uncaughtException handlers that call the REAL process.exit(1).
Across this file's vi.resetModules() reimports they accumulate on `process`, and
under CI timing a stray async rejection fired one while no process.exit spy was
active — killing the forked vitest worker ("Worker exited unexpectedly"), which
only surfaced once the full test lanes finished (they were pending at review time).
Keep process.exit spied for the whole file (beforeAll/afterAll) so a fatal handler
can never really exit mid-run, strip the handlers installFatalHandlers added in
afterAll (preserving vitest's own, snapshotted up front) before restoring the real
process.exit, and reset process.exitCode so the worker exits clean. Passes in
isolation and grouped; behavior under test is unchanged.

* fix(analyze): don't take the up-to-date fast path for an unregistered repo (#2264)
A prior 'analyze --name X' that hit a registry name collision writes meta.json
(meta-save runs before registerRepo) but fails before registering — leaving the
index up-to-date but UNREGISTERED. A later 'analyze --name X --allow-duplicate-name'
then matched the up-to-date gate and early-returned WITHOUT registering, so the
repo stayed invisible to list_repos/MCP and the CLI's assertAnalysisFinalized
rejected it. --allow-duplicate-name could never heal it.
This was latent on main, masked by the very close-hang this PR fixes: the lingering
process pushed the cli-e2e #829 step-3 analyze past its 60s spawn timeout
(status===null → the test's vacuous early-return). With the hang gone the analyze
exits promptly, exit 1 surfaces, and the bug becomes deterministic on all platforms.
Fix: the up-to-date fast path now short-circuits only when the repo is actually
registered (new isRepoRegistered helper, sharing assertAnalysisFinalized's exact
canonical/case-folded membership check). An indexed-but-unregistered repo falls
through to the pipeline, which registers it honoring allowDuplicateName. Already
registered repos keep the fast path unchanged.

* fix(analyze): gate up-to-date self-heal on --allow-duplicate-name (#2264)
The prior commit healed every up-to-date-but-unregistered repo by falling through
to register it — which broke the #1169 guard: a plain `analyze` of an up-to-date
repo whose registry entry is missing MUST fail loudly ("Analysis did not finalize")
rather than silently register a possibly half-finalized index.
Distinguish the two causes of "unregistered":
- collision-rejected + user re-runs with --allow-duplicate-name → explicit intent
to register, so fall through to the pipeline and register it (#829).
- plain analyze, registry missing/wiped → keep the #1169 fail-loud behavior.
So self-heal is gated on options.allowDuplicateName; isRepoRegistered is only read
on that opt-in branch, so the common fast path keeps its single-stat cost. Both
cli-e2e guards (#1169 fail-loud, #829 heal) now pass.

* fix(server): skip the native close on analyze-worker SIGTERM cancellation (#2264 P2)
cancelJob() / the 30-min timeout (analyze-job.ts) send SIGTERM to the forked
analyze worker, but its SIGTERM handler still did a full `await closeLbug()`
(native conn/db teardown) — even though normal completion now skips it via
skipNativeCloseOnExit. A cancelled or timed-out --pdg server analyze could
therefore still hit the LadybugDB ClientContext destructor double-free, or block
behind the in-flight COPY's connection lock before exiting.
Mirror the CLI SIGINT path: a best-effort CHECKPOINT with
closeLbug({ skipNativeClose: true }) bounded by a 2s Promise.race timeout, then
process.exit(0) (which reclaims the handles). A CHECKPOINT failure is reported to
the parent over IPC rather than swallowed; the exit is in .finally so it always
fires.

* test(cli): pre-set NODE_OPTIONS heap cap so ensureHeap can't re-exec (#2264 CI)
Root cause of the ubuntu-coverage-only failure (3/3 CI runs, passing locally):
analyzeCommand calls ensureHeap() (analyze.ts:715), which RE-EXECS the process —
spawning `node <heap-flags> <argv>` with vitest's argv — unless NODE_OPTIONS
already carries --max-old-space-size (analyze.ts:498). That re-exec killed the
forked vitest worker ("Worker exited unexpectedly" → the assertion never ran).
It only reproduced on the memory-constrained CI runner because locally a high V8
heap-size-limit also short-circuits ensureHeap (analyze.ts:501).
Reproduced locally with NODE_OPTIONS="--no-warnings" (no heap cap) → same failure;
fixed by pre-setting --max-old-space-size in beforeAll (restored in afterAll), the
same workaround cli-e2e uses. Verified: passes under the repro condition, normally,

* fix(server): worker asserts finalization before reporting complete (#2264 P2)
The forked analyze worker reported {type:'complete'} straight after runFullAnalysis,
so a server/web analyze of a half-finalized repo (meta.json written but the global
registry entry missing — a prior collision-aborted run, or a wiped registry) was
reported successful while the repo stayed unregistered/invisible to list_repos. The
CLI already guards this with assertAnalysisFinalized; the worker did not.
Extract the run -> finalize -> report contract into a side-effect-free
analyze-worker-core seam (the entry module's top-level process.on handlers make it
untestable directly) and call assertAnalysisFinalized before sending complete — a
failure is reported as {type:'error'} instead of a false success. The seam is
dependency-injected and unit-tested with fakes; the entry module wires the real deps
and keeps owning process.exit.

The worker SIGTERM handler unconditionally sent {type:'error','Analysis cancelled'}
and didn't coordinate with the message handler that sends complete, so a cancel near
the finish line could report a cancelled job complete, or a late SIGTERM could flip
an already-complete job to failed.
Add a single terminal-outcome claim (createTerminalClaim) shared by the message
handler and the SIGTERM handler: whoever claims it first reports its terminal
message; the other skips its terminal send. Single-threaded JS makes the
check-and-set atomic. The cleanup + process.exit still run regardless.

Defense-in-depth complement to the worker terminal-claim: the launcher's message

late worker IPC message (a SIGTERM-driven 'error' after 'complete', or vice versa)
could re-release the repo lock and flip the reported status. (Touches parent-side
files outside the original PR diff — deliberate, clearly-scoped.)
- analyze-job.ts updateJob: drop any update once the job is already terminal (the
transition INTO terminal still applies, since status isn't terminal yet then).
- analyze-launch.ts message handler: return early when the job is already terminal,
mirroring its sibling exit handler.

connection (dbPath provided) must NOT take the singleton lock, or temp-conn callers
would needlessly contend with it. Add the negative-gate assertion so a regression
that unconditionally locks is caught.

* test(cli): assert the force-exit forwards process.exitCode, not a hardcoded 1 (#2264)
The existing cases asserted process.exit(1), but since the error catch always sets
exitCode=1 they couldn't distinguish forwarding (process.exit(process.exitCode ?? 1))
from a hardcoded 1. Add a case on the alreadyUpToDate path — which returns without
setting exitCode or calling process.exit — with a pre-set exitCode=2 and isLbugReady
forced true, asserting the wrapper force-exits with 2. Proves the exitCode-forwarding
branch.

* refactor(lbug): replace skipNativeClose flag with a dedicated closeLbugBeforeExit() (#2264)
The "skip the native close only when a process.exit is guaranteed to follow"
invariant was enforced by convention across ~4 call sites via a boolean option on
closeLbug — the exact foot-gun the review flagged. Encode the contract in the name
instead:
- New closeLbugBeforeExit() (CHECKPOINT via flushWAL, then return without the native
close); closeLbug() drops the option and is the plain real-close again.
- run-analyze success + error paths: options.skipNativeCloseOnExit ?
closeLbugBeforeExit() : closeLbug(). CLI SIGINT + worker SIGTERM call
closeLbugBeforeExit() directly. skipNativeCloseOnExit stays on AnalyzeOptions as the
caller's "I will exit" signal.
- lbug-checkpoint.test: assert closeLbugBeforeExit exists + has no native close, and
match `closeLbug =` precisely so it doesn't prefix-match the new function.
- Retarget the conn-serialization integration case to closeLbugBeforeExit(); add the
new export to the 12 analyze-*.test.ts lbug-adapter mocks.

* refactor(lbug): extract isSharedSingletonConn predicate for the lock gate (#2264)
The targetConn === conn object-identity gate (decides whether an op takes
withConnLock) was duplicated inline in queryAndDrain and deleteNodesForFile with
its own explanatory comments. Extract a single isSharedSingletonConn(c) predicate
with the rationale in one place; both sites route through it. Behavior unchanged —
covered by the lock-routing tests' positive (singleton locks) and negative
(temp-conn skips) cases.

* refactor(lbug): share the bounded checkpoint-then-exit cleanup (SIGINT/SIGTERM) (#2264)
The CLI SIGINT handler (analyze.ts) and the worker SIGTERM handler (analyze-worker.ts)
had near-identical Promise.race([closeLbugBeforeExit, timeout]).finally(exit) blocks
with separately-hardcoded 2s timeouts. Extract boundedCheckpointBeforeExit into a
shared shutdown-helpers module — parameterized by exit code, an optional flush-error
reporter (worker reports over IPC), and an optional beforeExit hook (CLI flushes the
logger). checkpoint + exit are injectable test seams, so it's unit-tested without the
real LadybugDB close or process.exit.

* refactor(storage): extract registryPathEquals for the registry case-fold compare (#2264)
The Windows case-insensitive / POSIX case-sensitive registry-path comparison was
duplicated across 6 sites (registerRepo dedup, the fresh-merge findIndex,
removeRepo/removeBranchIndex local 'matches' helpers, isRepoRegistered, and the
path-match lookup). Extract a single registryPathEquals(a, b) predicate so every
registry lookup/dedup/finalize check answers identically; route all 6 through it.
No behavior change — repo-manager + finalize-invariant suites pass (incl. the
Windows case-fold case).

* feat(lbug): runtime-guard streamQuery against the WAL-checkpoint driver (#2264)
streamQuery is deliberately not wrapped in withConnLock (its per-row callback can
re-enter the adapter), so its unlocked per-row reads could race a CHECKPOINT on the
shared connection — the corruption window the lock serializes everything else
against. That invariant was comment-only, safe today only because the serve/read
path forks analyze workers. Make it enforced:
- lbug-adapter: a walDriverActive flag + markWalDriverActive(bool); streamQuery
throws an actionable error when the driver is active.
- wal-checkpoint-driver: arm the flag on start, disarm in stop() AFTER the in-flight
CHECKPOINT drains (clearing earlier would briefly allow a race).
A future in-process analyze overlapping a stream now fails loud instead of
corrupting native state. (reentrancy test's lbug-adapter mock gains the new export.)

* docs(lbug): explain why closeLbugBeforeExit skips finalizeLbugSidecarsAfterClose (#2264)
Document the deliberate trade-off: the skip-close path intentionally does NOT run
the sidecar-finalize step that safeClose runs after a real close. It's designed for
released WAL handles; running it with the connection still open risks a Windows
file-lock on the in-use WAL. The CHECKPOINT already made the index durable and the
next run's preflightLbugSidecars reconciles residual WAL — the deferral is the
accepted cost of skipping the native close to dodge the destructor double-free.
