Review of the 11 source files, the 13 test files, and the four open threads from the previous round. Findings are inline; this body carries only what has no anchor.
Severity grading for a stacked PR. Nothing in :quickbuild:core is constructed by production code at this commit - the session manager lands in PR 8 - so a strict "no current caller can reach it" test would grade every finding here MINOR and say nothing useful. I graded on consequence once the stack lands, and each comment says where reachability actually comes from.
Previous round, re-checked at 9ffdae0 by reading the code, not the replies:
ProxyAppInfo.kt:185(Gson array cast) - fixed.jsonArray()is nowget(key) as? JsonArray, and all six array reads (classpath,payloadJars,components,supertypes, and bothstringArraycallers) route through it. NogetAsJsonArrayremains in the file.QuickBuildProjectLayoutTest.kt:4(unusedreportimport) - fixed. The import is gone at head.README.md:11(link toProxyAppBuildRunner.kt) - accepted as declined. Verified: the file is absent at this commit andProxyAppLauncher.kt, the other linked file, is present. A transient of reviewing a stack PR-by-PR, not a broken link at the stack tip.ProxyAppInstaller.kt:241(re-prompt races an arriving verdict) - still open. Replied in that thread with a second path to it that needs noresolveUidlag, which bears on the "not reproduced on device" hold.
Not independently verified: the :quickbuild:core:test run and the 98.2% / 90.1% JaCoCo numbers in the description are taken as stated - I did not re-run them. The test suites themselves read as unusually thorough; the death-listener race in DaemonProcessClientEdgeTest in particular is pinned both by a repeated-interleaving test and by a deterministic mechanism test, which is the right pair.
Areas checked with nothing to report: ASCII-only in all changed Kotlin (verified by grep, clean); no strings, UI, accessibility, font-scale, or plugin-API surface in this PR; no new dependencies; no persistence beyond the plain-file counter, so ADR 0001 does not apply; module boundaries hold (service depends down on data/domain, and the app-facing work stays behind QuickBuildProvisioner/InstalledPackages/QuickBuildPaths interfaces).
This repo has no written approve/request-changes rule; REVIEW.md is a coaching doc and CLAUDE.md ties only the Jira QA transition to "no outstanding critical, high, or medium findings". Verdict computed under this skill's default table and reported separately.

Requesting changes on two IMPORTANT findings, both addressable here rather than deferred to PR 8:
DaemonProcessClient.kt:470- makependingper-spawn so a replaced child's watcher fails only its own requests. As it stands, a compile in flight across a daemon restart is orphaned and holdsrequestMutexfor the full 300s, blocking the next session'sconfigurebehind it.ProxyAppInstaller.kt:185- confineisSameContentand thepackages.*reads toDispatchers.IO. Hashing two full APKs on the session thread contradictsquickbuild/docs/concurrency.md's rule that that thread must never block.
The six MINORs and three NITPICKs are yours to triage; none of them block. Details and the previous-round re-check are in the review above.

Important 2: line/column asInt threw NumberFormatException on non-numeric string primitives -> runCatching like the protocol-version read, degrading to absent; covered by `a non-numeric line or column string reads as absent instead of throwing`. Important 3: the request write had no bound, so a wedged child holding a full stdin pipe parked the mutex forever and shutdown() deadlocked on the writer monitor -> write runs on the client scope under requestTimeoutMillis with destroyForcibly on expiry, and shutdown()'s EOF close moved off the teardown path; covered by `a request the daemon never reads times out instead of wedging the client` and `shutdown is not deadlocked by a write the daemon never reads`.

Akash's 2 September round on the provisioning slice and the daemon client. - The daemon's death watcher drains the stdout pump before failing pending requests. A child that writes its reply and exits in the same breath had that reply still in the pipe when waitFor returned, so start() reported a failure from a daemon that had answered. Bounded at 2s so a wedged pump cannot hold the watcher. #1719 (comment) - start() takes a mutex: two overlapping starts each spawned a child JVM and only the second was tracked, orphaning the first. #1719 (comment) - The shutdown kill path runs NonCancellable, so a cancelled teardown cannot leave the child alive with the client believing it stopped. #1719 (comment) - A rejected configure carries the daemon's own first diagnostic instead of a bare "Daemon rejected configuration". #1719 (comment) - requestTimeoutMillis's KDoc says it is applied per phase, so a caller can read the worst case as up to twice it. #1719 (comment) - A low-memory teardown the daemon never came back for expires after 60s instead of being held for the rest of the session and fired at an unrelated later daemon. The controller takes an injectable clock for the test. #1719 (comment) - QuickBuildClobberCheck does its PackageManager reads on an injected IO dispatcher; both entry points are suspend now. #1719 (comment) - QuickBuildProjectLayout's KDoc drops the "pure File arithmetic" claim: allSources and moduleDirs walk the tree and belong off the main thread. #1719 (comment) - ProxyAppInstaller's classify returns a Verdict rather than suspending inside a select clause, so uid resolution happens after the await instead of under it, and a plain SUCCESS no longer times out inside resolveUid and re-prompts. #1719 (comment) - The provision README no longer links a file that lands in a later PR. #1719 (comment) - The scratch-filesystem test asserts the field is cleared on shutdown, which nothing pinned. #1719 (comment) - Fakes.kt loses two inline coroutine FQNs and FakePaths gains a KDoc. #1719 (comment) The pump-drain fix is not pinned by a regression test. With the drain line deleted, DaemonProcessClientEdgeTest passed six of six isolated runs, so the race does not reproduce on this machine; the fix stands on the ordering argument above, not on a test that goes red without it.

ktlint joins start()'s single-expression body onto one line now that it delegates to startLocked. Standalone so it does not read as a behavioural change. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017o3nPrBbGi2XYkMUGavG2A
…ncancellable Answers review threads 3926544377 and 3926550446 on PR #1719. shutdown() now takes startMutex and delegates to an unlocked shutdownLocked(), which start's own pre-spawn stop and its failure tail call directly - the mutex is not reentrant. A teardown landing mid-spawn now waits for the child to be installed instead of reading a null handle and leaving it with no death watcher and nothing to stop it. The polite SHUTDOWN request moves inside the NonCancellable block. request() rethrows CancellationException, so a cancellation one line above it skipped the kill, the pipe close and the handle clear - the leak the block exists to prevent.

… not terminal Answers review threads 3926544390 and 3926544402 on PR #1719. ensureInstalled promises never to throw, but its InstalledPackages reads run in a plain coroutineScope, so any of them throwing cancels the scope and raises out of it. All five reads now go through one readPackages helper that maps a throw to null: the two Akash named (awaitStampChange, resolveUid) plus three he did not - the initial stamp, the existing uid, and the installed-APK lookup behind isSameContent. isTerminal's omission of Status.OTHER stays. OTHER is the mapper's catch-all for an unrecognized status and the receiver's action is exported, so making it terminal would let a stray external intent abort a legitimate install. The KDoc now says that and names the test that pins it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017o3nPrBbGi2XYkMUGavG2A
…g branch Answers review threads 3926544396, 3926551516, 3926550898 and 3926552396 on PR #1719. classpath and payloadJars now go through the same stringArray helper their siblings use, which drops blanks. A blank resolved to the project root, putting the whole tree on the daemon's compile classpath. shrinkIfPending checks the pending-teardown deadline before the isRunning branch. The common shape is a trim raised by a Gradle build: it defers, and the retry lands minutes later with the daemon healthy, where the deadline never ran - so it tore down a daemon the user is using over memory pressure long gone. Adds the file-at-target generation-store test that was promised but absent, so the arm that preserves the counter is executed, and drops the last fully-qualified withContext call site in the test fakes.

… one breath The watcher's drain join (wait for stdout EOF before failing the pending requests) had no test: the existing mid-request death script exits without writing a reply, so it lands on the same Failed result with or without the join. This script writes the reply and exits at once, behind a burst of id-less lines that keeps the pump busy past waitFor, and asserts the Ok arrives. Verified against the join removed: fails 3 of 3 runs for the reason it is named for; with the join, passes 3 of 3.

… exit is a death 7cc417596 marked a child deliberate until its configure succeeded, which closed the "dies during configure" case but opened the opposite one: a child that writes its configure reply and exits in the same breath can be observed by the death watcher before the start has read that reply and cleared the marker, and its death is swallowed. The existing test for an unexpected exit after configure caught it on the third run. Spawn.owned is a CompletableDeferred the start settles - true once the reply passed the version check, false on every other exit of startLocked including cancellation - and the watcher waits on it after failing this child's pending requests (which is what lets a start still inside its configure round trip finish). The marker goes back to starting false and means only what shutdown says it means.

The daemon sends diagnostics on an ok compile reply too, and the client read them only off failures, so no warning from a quick build could reach the user. CompileOutput now carries them; the executor's success arm on the orchestration branch and the output lines on the app branch surface them at the restack. Dex and relink are unchanged: the daemon builds those replies through DaemonResponse.ok, which carries none. #1719 (comment) Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XkGof8cLt23LkxZ8MKzin2
Every op reports durationMillis and the client read none of them, so the daemon's in-process cost could not be set against the client's round trip.

InstallCouldNotStart reached the user with nothing in logcat behind it: both launchInstall catches dropped the throwable and the !started arm returned silently.

readPackages mapped a throw to null, and awaitStampChange read a null initial stamp as "absent, so any stamp counts" - one transient PackageManager throw over an installed package made the first poll match the old stamp and report an install that never ran. The pre-install read now says Unknown when it threw, and the poll establishes its baseline from the first successful read before waiting for a change. #1719 (comment) Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XkGof8cLt23LkxZ8MKzin2

…ed dispatcher FileGenerationStore and QuickBuildScratch did their file I/O inline, and both are called from the session thread that concurrency.md says must not block - the store on FUSE-backed project storage, the scratch sweep a deleteRecursively per leftover tree. Both now suspend and hop to an injected I/O dispatcher, as ProxyAppInstaller and QuickBuildClobberCheck already do. GenerationStore's contract follows, and GenerationTracker reads it through a suspend open() instead of in its constructor. The save KDoc's throws sentence now also covers the staged write, which sits outside the rename fallback. Callers on the orchestration branch (ProxyAppBuildRunner, QuickBuildSessionManager) adapt at the restack. #1719 (comment) #1719 (comment) Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XkGof8cLt23LkxZ8MKzin2
…rovision leaves QuickBuildProjectLayout's off-main-thread warning named the private moduleDirs instead of the public watchedRoots and watchedFiles that call it.

… child whose start was cancelled configured and scratchFsType move onto Spawn, so a replaced child's late death watcher can no longer clear the flag its successor just set; isRunning reads the current Spawn alone. A start cancelled inside its configure round trip now shuts the child down before rethrowing, where before nothing ever stopped it. A rejected configuration comes back as the daemon's own BuildFailed, with its diagnostics, instead of being flattened into a Failed message.

…ch save uniquely A torn or appended-to counter file loaded as null, which is a reused generation; only the first line is the counter now.

A PackageManager read that throws used to propagate out of the tap handler; it now reads as "confirm", since an extra tap is cheaper than a clobbered build.

Installer KDocs: the timeout budget covers the verdict, not the uid read that follows it; a nameless broadcast errs toward a reported failure. Drop the ticket-era "Defect T12" label from a test comment. concurrency.md: the request timeout applies per phase, so up to 600 s.

Akash on #1719: the class KDoc exists to tell a caller which members are expensive, and it left out resDirs(), whose isDirectory filter stats the disk. A caller reading "the path accessors are arithmetic and cost nothing" would have counted resDirs() among them. It stats rather than walks, so it is cheaper than the three already named; the sentence says that rather than lumping it in with them. Comment only. No behaviour change.

ADFA-4128
Part 7/11 of the stacked split of #1669 (requested by Akash). Base: feature/ADFA-4128-qb-06-core-deploy. Stack overview + review mechanics: PR 1 (#1713). Terms are defined in quickbuild/README.md (lands in PR 1).
Makes sure the two things Quick Build needs before it can start — an installed app to reload into, and a live compiler — are ready, and that it never fights a standard Run for the same install slot.

b1e38b940f.:quickbuild:core:testV8DebugUnitTestran at the stack tip7715c40548on 2026-09-25, with all four core slices applied: 1,234 tests, 0 failures. Slices 1-3's suite was not run alone at this PR's own head in this pass, and only thev8Debugvariant was run; the other five variants were not [unmeasured].Restacked onto
stagec263653bcfon 2026-09-24; head nowb1e38b940f. Re-verified at the stack tip7715c40548on 2026-09-25, which contains this PR's commits and the roughly 6,970 lines of stage work the restack pulled in:spotlessCheckgreen (34 of 34 tasks executed,--rerun-tasks) and:app:assembleV8Debuggreen (254.1 MB APK). The A56 walk ran on 2026-09-24/25 atf6ef914653, that tip plus ADFA-4931's 12 commits: 25 of 25 cases, 24 pass, 0 fail, 1 blocked (T19, Compose — no project on the device configures offline, so Quick Build is never reached). The base isorigin/stage's current head, so there is no stage drift. All six unit suites were run once at the stack tip7715c40548on 2026-09-25::quickbuild:core1,234,:quickbuild:daemon234,:quickbuild:protocol22,:quickbuild:runtime307,:gradle-plugin155 and:app1,312 — 3,264 tests, 1 failure and 5 skips. The failure and one skip are:app's (PR 11 has the detail); the other four skips are:gradle-plugin's documented@Disabledcases.Coverage — the per-package table below is the 2026-08-21 slice, rows and total alike, so it stays internally consistent; the rewritten slicer reports per-PR and per-module totals rather than per-package, so those rows cannot be refreshed [unmeasured at this head]. The TOTAL row is this PR's own diff re-sliced at the stack tip
7715c40548on 2026-09-25, on REVIEW.md section 5's changed-lines non-UI basis [measured]; the superseded 2026-08-21 figure sits beside it in the Note. Like that pass, it credits every test in the stack, not only this PR's own. Also re-measured::quickbuild:coreas a whole reads 96.7% line / 91.6% branch at the stack tip7715c40548on 2026-09-25.…quickbuild.data…quickbuild.service.provision…quickbuild.service.session12 source files in the diff, all 12 measured.
