Inline comments:
In `@README.md`:
- Around line 80-92: The runtime cache path description is incomplete: the dex
filename pattern in the README should match DexFactory.getDexFile. Update the
documentation around ClassResolver and DexFactory to state that the generated
dex is written with the thumb suffix (class name plus dex thumb) rather than
just <name>.dex, so the troubleshooting guidance reflects the actual on-disk
path.

In `@test-app/runtime/src/main/cpp/CallbackHandlers.cpp`:
- Around line 1348-1361: Wrap CallbackHandlers::TerminateAllWorkersCallback in
the same V8 exception handling pattern used by the neighboring worker callbacks
so any exception from WorkerWrapper::TerminateChildren or child->Terminate() is
converted to NativeScriptException instead of escaping across V8. Locate the fix
in TerminateAllWorkersCallback and apply the same try/catch boundary and
rethrow/forwarding behavior already used in the adjacent callback handlers that
call into WorkerWrapper.

In `@test-app/runtime/src/main/cpp/HMRSupport.cpp`:
- Around line 1249-1251: configureRuntime() is leaving stale resolver state
behind because SetImportMapEntries() and SetVolatilePatterns() are only called
when the parsed lists are non-empty. Update the logic in configureRuntime() so
an explicit empty import map or volatile pattern list still invokes the
համապատասխան setter and replaces any previous session values. Keep the existing
parsing helpers like ReadImportMapEntries() and ReadVolatilePatterns(), but
remove the empty-check gate before SetImportMapEntries() and
SetVolatilePatterns() so cleared runtime config truly resets resolver state.
- Around line 1044-1063: The detached prefetch worker in
HMRSupport::KickstartHmrPrefetchUrlsSync can still update g_prefetchCache after
the request has timed out or global HMR state has been cleaned up. Add a
cancellation/liveness check tied to the current prefetch context (for example in
the ctxCopy worker path before writing to the cache) so stale workers exit
without mutating shared state. Apply the same guard to the matching detached
fetch path referenced by the related block, and keep the cache write under
g_prefetchMutex only when the context is still valid.
- Around line 664-668: The per-fetch URL entry trace in HMRSupport’s HTTP-ESM
fetch path is still guarded by the script-loading flag instead of the new
httpFetchUrlLog setting. Update the conditional around the DEBUG_WRITE in the
fetch entry flow to use the httpFetchUrlLog-backed check (for example, the
getter or helper associated with httpFetchUrlLog) so enabling that setting alone
turns on the URL trace. Keep the existing fetch entry logging in the same
location, just swap the gate used by the HTTP fetch diagnostics path.
- Around line 580-586: `g_prefetchCache` is using raw URLs instead of the same
canonical identity used by `MarkUrlsForCacheBust()`, so equivalent URLs can miss
cache hits or leave stale prefetched bodies behind. Update the prefetch cache
read/write/eviction paths in `HMRSupport.cpp` to normalize URLs before using
them as keys, and make the affected prewarm and invalidation flows use the same
canonicalized key consistently. Use the existing `MarkUrlsForCacheBust()` logic
as the reference for canonicalization and apply it wherever `g_prefetchCache` is
accessed.

In `@test-app/runtime/src/main/cpp/MetadataNode.cpp`:
- Around line 1798-1816: The module-name normalization in
MetadataNode::GetModulePath should strip any query string or fragment before
checking for .mjs/.js suffixes, since cache-busted URLs can bypass the current
extension trimming. Update the logic around the normalized/fullPathToFile
handling to remove everything after ? or # first, then keep sanitizing all
non-identifier characters (including ?, =, &, #) before the Util::SplitString
step.

In `@test-app/runtime/src/main/cpp/ModuleInternal.cpp`:
- Around line 292-321: The promise-drain logic in ModuleInternal.cpp currently
exits successfully when evalResult remains kPending after the maxAttempts loop.
Update the HTTP module evaluation path in the promise handling block to detect
the still-pending state after the loop and throw a timeout/pending-evaluation
NativeScriptException instead of falling through. Keep the existing
rejected-path behavior intact and make the new error message clearly identify
the module path and that evaluation never completed.

In `@test-app/runtime/src/main/cpp/Runtime.cpp`:
- Around line 101-113: The fatal signal handler in Runtime.cpp currently
heap-allocates via abi::__cxa_demangle and frees the result, which makes the
crash path depend on the allocator. Update the backtrace formatting logic around
the symbol lookup to avoid any allocation in this handler: keep info.dli_sname
unchanged for logging, remove the demangling/freeing work from this path, and
move demangling to an offline or non-signal-handling context if needed. Use the
existing backtrace loop and __android_log_print call site as the place to
preserve safe, allocator-free logging.

In `@test-app/runtime/src/main/cpp/URLImpl.cpp`:
- Around line 55-86: The URL.searchParams getter caches a URLSearchParams
instance, but the SetSearch path does not refresh that cached object when
url.search is reassigned, so it can become stale. Update the URLImpl URL/search
handling so the existing _searchParams object is synchronized with the new
search string in SetSearch instead of replacing or leaving it unchanged, and
keep the URLSearchParams methods on the cached instance consistent with the
updated URL.

In `@test-app/runtime/src/main/cpp/Version.h`:
- Around line 1-2: The checked-in fallback for the runtime commit SHA in
Version.h is still the placeholder string, so startup logs can show a bogus
value. Update the Version.h literal or make test-app/runtime/build.gradle
replace the exact symbol used by NATIVE_SCRIPT_RUNTIME_COMMIT_SHA so packaged
release builds include the real git SHA instead of the fallback.

Nitpick comments:
In
`@test-app/app/src/main/assets/app/tests/testNodeBuiltinsAndOptionalModules.mjs`:
- Around line 20-21: The assertion in testNodeBuiltinsAndOptionalModules.mjs is
too permissive because it accepts both leading-slash and no-leading-slash
results from mod.fileURLToPath. Update the test around the fileURLToPath check
to assert the exact expected Android value directly, using the same
mod.fileURLToPath symbol and expect call, so the test fails if the path handling
changes unexpectedly.

Inline comments:
In `@test-app/runtime/src/main/cpp/HMRSupport.cpp`:
- Around line 697-729: Remove the process-wide keep-alive workaround guarded by
sKeepAliveDisabled, including the System.setProperty("http.keepAlive", "false")
JNI calls. Preserve the existing per-request Connection: close header and retry
path so the workaround remains scoped to loader requests.
- Around line 1015-1044: Update KickstartScheduleUrls so it does not create one
detached thread per URL or call EnterPending before unbounded thread
construction. Build a shared URL queue and start at most maxConcurrent worker
threads that consume it, ensuring thread creation is bounded and construction
failures cannot leave pending state inconsistent.

In `@test-app/runtime/src/main/cpp/ModuleInternalCallbacks.cpp`:
- Around line 751-789: Update RemoveModuleFromRegistry and InvalidateModules to
also clear the corresponding handle in g_vendorModuleCache whenever the
canonical key is an ns-vendor://<id> entry. Keep registry removal and existing
URL eviction behavior unchanged, and ensure both APIs evict the vendor cache
entry so ResolveFromVendorRegistry cannot return the stale module.
- Around line 580-592: The declaration generation in ResolveFromVendorRegistry
must not use export names that are JavaScript reserved words, even when
IsValidJSIdentifier accepts them. Detect reserved keywords and emit a safe local
alias for the declaration, then re-export that alias under the original name;
retain direct declarations for non-reserved valid identifiers.
- Around line 1728-1741: Update the dynamic-import evaluation flow around
blobMod->Evaluate() to await its returned promise before resolving the module
namespace, propagating rejected evaluation promises to the import resolver.
Apply the same promise chaining and fulfillment-only namespace resolution to the
other dynamic-import branches, while preserving the existing synchronous error
handling.

In `@test-app/runtime/src/main/cpp/Runtime.cpp`:
- Around line 225-240: Update the signal-handler setup around sigaltstack and
the sigaction calls to check each return value and log or otherwise surface
registration failures. Ensure failures for the alternate stack and every signal
in this initialization path are reported, while preserving the existing handler
configuration.

Inline comments:
In `@test-app/app/src/main/assets/app/tests/testNsModule.js`:
- Around line 35-44: In test-app/app/src/main/assets/app/tests/testNsModule.js
lines 35-44, save global.__NS_HMR_BOOT_COMPLETE__ before the spec and restore
that saved value during cleanup instead of forcing false. In lines 88-104, move
configureLoader into beforeEach/afterEach so each spec restores the prior loader
configuration and re-installs the boot-time canonicalization vocabulary after
execution.

In `@test-app/app/src/main/assets/app/tests/testRemoteModuleSecurity.js`:
- Around line 146-153: Rename the spec describing
com.tns.Runtime.isRemoteUrlAllowed so its title reflects that it verifies the
helper exists and preserves the debug bypass, not refusal of lookalike-host
prefixes. Keep the assertions unchanged; do not claim boundary matching is
tested unless a separate directly reachable test is added.

In `@test-app/runtests.gradle`:
- Around line 70-77: Remove ignoreExitValue = true from the
android_unit_test_results.xml cleanup task so failures from the run-as removal
command stop the flow instead of allowing stale results to remain; keep the
existing rm -f cleanup behavior and platform-specific command handling
unchanged.

In `@test-app/runtime/src/main/cpp/HttpLoader.cpp`:
- Around line 872-888: Replace the global JSON lookup and manual stringify
invocation in the importMap object branch with v8::JSON::Stringify, preserving
the existing result-to-UTF-8 conversion and jsonStr assignment only when
serialization succeeds. Remove the ToLocalChecked calls and unchecked JSON
object/function casts from this path.
- Around line 230-254: Replace the unsynchronized globals used by
SetCanonicalizationConfig, ResetCanonicalizationConfig, and
CanonicalizeHttpUrlKey with an atomically published immutable shared snapshot,
using the existing project conventions for atomic shared-pointer access. Publish
a new const CanonicalizationConfig on configure and a null snapshot on reset;
have CanonicalizeHttpUrlKey acquire one snapshot at entry, check it for
configuration state, and use that stable snapshot throughout the call instead of
g_canonConfigured or g_canonConfig.
- Around line 700-717: Update the read loop around HttpLoader’s
CallIntMethod(inStream, readMethod, buffer) to check for a pending JNI exception
immediately after each read; record the exception and break before handling n ==
0. Preserve normal EOF and successful reads, while ensuring the recorded
exception is propagated or handled by the surrounding loader flow after cleanup.
- Around line 765-806: Update FetchModuleBodyAsync’s worker thread to detach
from the JVM after invoking completion and completing all JNI-related work. Add
an exception-safe scope guard at the end of the thread lambda so detachment
occurs on normal completion and when an exception exits the lambda, without
changing the existing fetch or callback behavior.
- Around line 808-817: Remove the immediate boot pumping from
MaybePumpJSThreadDuringBoot, or defer its execution until ResolveModuleCallback
and the LoadHttpModuleForUrl/HttpFetchText/InvokeHttpFetch call chain has fully
returned. Ensure neither PerformMicrotaskCheckpoint nor ALooper_pollOnce can
re-enter JavaScript while module instantiation is still active.

In `@test-app/runtime/src/main/cpp/ModuleInternal.cpp`:
- Around line 53-85: Update PromiseRejectionMessage so property reads on the
rejection reason are enclosed in a local v8::TryCatch, covering the
errorObj->Get call and its result handling. Ensure any exception from a proxy or
throwing message getter is caught and does not remain pending on the isolate,
while preserving the existing diagnostic message behavior.

In `@test-app/runtime/src/main/cpp/Runtime.cpp`:
- Around line 342-355: Reduce the synchronous async-module drain deadline in
PumpPendingHttpModuleGraph in test-app/runtime/src/main/cpp/Runtime.cpp (lines
342-355) for the main thread and log when the deadline expires. Also update the
top-level-await handling in test-app/runtime/src/main/cpp/ModuleInternal.cpp
(lines 659-680) to reduce its 30-second main-thread bound or return the pending
promise instead of draining it inline.

In `@test-app/runtime/src/main/cpp/WorkerWrapper.cpp`:
- Around line 158-178: Bound the retry path in WorkerWrapper::DrainPendingTasks
using a looper-scheduled delay instead of spawning and detaching a std::thread
for each retry. Add the proposed kMaxDrainRetryAttempts and looper-thread-only
drainRetryAttempts_ state, increment attempts while onmessage is unavailable,
and reschedule only below the cap; once the cap is reached, fall through to the
existing per-message logging and discard handling. Reset drainRetryAttempts_ to
zero when a valid onmessage handler is found.

In `@test-app/runtime/src/main/java/com/tns/DexFactory.java`:
- Line 197: Update DexFactory.findClass so canonicalName only replaces '/' with
'.', preserving '$' for ordinary nested-class loading before
classLoader.loadClass. Apply underscore normalization only within
generated-proxy lookup, and add regression coverage for both nested-class
loading and proxy-name normalization.

In `@test-app/tools/try_to_find_test_result_file.js`:
- Around line 140-144: Update the result validation in
try_to_find_test_result_file to parse the file with the existing XML parser
before calling process.exit(0), and require a testsuites root so only
verifier-ready artifacts succeed. Replace the startsWith("<?xml") check in both
branches, preserving retry behavior when parsing or root validation fails and
accepting valid XML without an XML declaration.

Nitpick comments:
In `@test-app/runtime/src/main/cpp/HttpLoader.cpp`:
- Around line 525-532: Restrict the synchronous retry in
PerformHttpFetchOnceSync’s caller to transport failures by requiring status == 0
alongside !ok before sleeping and retrying. Apply the same status == 0 gate to
the retry condition in the asynchronous path, while preserving existing logging
and retry behavior for transport errors.
- Around line 841-848: Update InstallDevFunction to report installation failures
through a boolean result instead of using ToLocalChecked() and Check(), while
preserving successful registration behavior. Change each core-member call in
BuildNsModuleBinding to inspect and propagate that result, matching the existing
canonicalizeHttpUrlKey failure path and returning false when any installation
fails.
- Around line 775-776: Replace the per-call detached thread created around the
fetch logic in HttpLoader with a small fixed-size worker pool and synchronized
work queue. Route each URL/completion task through the queue, enforce a fixed
maximum number of concurrent requests, and preserve completion delivery and
existing fetch behavior while preventing one worker thread from being created
per module URL.

- Line 143: Validate runOnDeviceOrEmulator before constructing adbPrefix,
allowing only -d or -e, so the command passed to execAndStream cannot contain
shell metacharacters; alternatively replace the shell-based invocation with an
argument-array API such as execFile while preserving the existing adb pull
behavior.

pollForResults; catch the failure, emit a clear diagnostic, and preserve the
existing polling behavior by allowing the next scheduled poll to run.
