📝 Walkthrough
WalkthroughAdds the Quick Build daemon protocol, process client, project metadata and layout models, scratch and generation storage, daemon lifecycle control, proxy-app installation, clobber checks, provisioning contracts, and extensive unit and integration tests. ChangesQuick Build runtime
Proxy-app provisioning
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The change adds Quick Build app provisioning and daemon communication, but malformed app metadata can currently crash parsing instead of being rejected, and a timeout race can trigger a duplicate install prompt; an unused import also causes the Kotlin style check to fail. These are bounded but concrete merge-readiness issues, so the PR should not merge until corrected. Sequence Diagram(s)sequenceDiagram

Gson JsonObject getAsJsonArray behavior when member is not a JsonArray ClassCastException
💡 Result:
When using the JsonObject.getAsJsonArray(String memberName) method in Gson, if the specified member exists but is not a JsonArray (e.g., it is a JsonObject or JsonPrimitive), the method will throw a ClassCastException [1][2][3]. This occurs because the implementation performs an explicit cast: return (JsonArray) members.get(memberName); [1]. If the member is absent, the method returns null [1][2][3]. In contrast, JsonElement.getAsJsonArray() (used on an instance of a JsonElement) behaves differently by design: it throws an IllegalStateException if the element is not a JsonArray, rather than a ClassCastException [4][5]. It is recommended to use the isJsonArray() check before calling these methods to avoid these runtime exceptions [4][5].

Guard every JSON array read in ProxyAppInfo.parse
JsonObject.getAsJsonArray(key) casts existing members directly. A scalar, object, or explicit null therefore throws ClassCastException. runCatching covers only the initial document parse, so the exception escapes parse and violates its null-on-failure contract.
Use a type-checked jsonArray helper for classpath, payloadJars, components, supertypes, and the keys read by stringArray. Add tests for non-array and null values.

Fixed. All five array reads now type-check the cast, so a scalar or an explicit null returns null as the KDoc promises. Severity is Minor rather than Major: the caller has an outer catch (Throwable), so today's symptom is a generic provisioning failure instead of the specific message, not a crash. 9031fdc

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Skip the re-prompt when a verdict already arrived.
The select clause bodies run inside withTimeoutOrNull(promptTimeoutMillis). classify calls resolveUid, which can suspend for up to UID_RETRIES * DEFAULT_POLL_MILLIS (5s). If the prompt window expires during those retries, the inner withTimeoutOrNull returns null even though the success broadcast was already received. The ?: run { ... } branch then commits a second install of bytes that are already on device, so the user can see an extra confirm dialog. The final outcome stays correct, because the completed verdict deferred resolves immediately on the second awaitVerdict().
Guard the re-prompt on deferred completion.

Held, not skipped. The fix is clear, but the trigger is a 5 s race that has not been reproduced on device, and writing the guard blind risks changing install behaviour for a sequence we have not observed. It goes in once there is one on-device repro of the duplicate dialog with the timing captured.

MINOR: still open at 9ffdae0, and it does not need the resolveUid lag to fire.
PENDING_USER_ACTION with a showable dialog is rejected by the first { } predicate at line 196, so the installer receives proof that a dialog is up and discards it. A user who taps Install at t=44s on a large APK gets SUCCESS at t=48s - the 45s prompt timeout has already re-committed and put a second confirm dialog in front of them for an app that just installed. No PackageManager lag required. The final outcome stays correct, because the completed verdict deferred re-resolves on the second awaitVerdict(), so this is a spurious dialog rather than a broken install - MINOR either way.
Two things that bear on the "not reproduced on device" hold:
- It makes
DEFAULT_PROMPT_TIMEOUT_MILLIS's KDoc claim - "Long enough that a user reading the dialog is never re-prompted under it" - false as written. It is long enough only if the user taps and the OS finishes installing inside 45s. - The guard need not be written blind. Recording that a
PENDING_USER_ACTIONwas seen, and skipping the re-issue when it was, changes behaviour only for sequences where the OS has already confirmed a dialog exists. That is the complement of the never-observed case the hold was protecting, not an overlap with it.
an install answered before the window is not re-prompted sets packages.uid before emitting SUCCESS, so it exercises neither path.

You are right that the PENDING_USER_ACTION path needs no PackageManager lag, and right that recording a seen PENDING_USER_ACTION changes behavior only for sequences where the OS confirmed a dialog exists — that answers the concern our hold was protecting. Fixing in this stack: remember the seen pending-user-action, skip the re-issue when set, correct the timeout constant's KDoc, and add the test that crosses the two. (Decision (a) answered 2026-08-31: Bryan adopted the guard, superseding the device-repro hold.)

Not taking it. The link resolves at HEAD: ProxyAppBuildRunner.kt was genuinely absent at this PR's own commit and lands in the next PR of the stack. That is an artifact of reviewing a stack PR-by-PR, not a broken link.

Fixed, the import is gone. The ktlint rationale does not hold: spotlessCheck is green on every PR in this stack with the import present, because the bare token report appears elsewhere in the file. Hygiene, not a red build. 9031fdc

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.

IMPORTANT: the replaced-child identity guard returns before the pending-request cleanup, so a request in flight across a daemon restart is orphaned.
A superseded compile holds requestMutex while awaiting its deferred. A teardown or rebaseline then calls start(), whose shutdown() cannot send the polite SHUTDOWN (the mutex is held), so the child is destroyForcibly()d and process = null runs while the kill is still async. This watcher wakes, sees process !== proc, and returns without completing pending. That compile's deferred is never completed, so it burns the full 300s requestTimeoutMillis still holding the mutex, and the new session's configure blocks behind it for the same 300s. quickbuild/docs/concurrency.md describes this interleaving directly: "a cancelled build's compile still runs to completion unheard - it can delay the next build".
Completing pending here would re-break what the guard fixed (the new session's own configure is in the same map). Make pending per-spawn, the way deliberateStop already is, so each watcher fails only its own child's requests. Not reachable at this commit - nothing constructs the client yet - but it becomes reachable with the session manager in PR 8.
There was a problem hiding this comment.
Confirmed, including the mutex hold: the orphaned request burns its full timeout and the next configure queues behind it. Fixing in this stack: the per-spawn state (process, writer, pending, stop marker) becomes one object, so a watcher fails only its own child's requests — deliberateStop already shows the shape.

IMPORTANT: ensureInstalled does blocking file and binder I/O on the caller's dispatcher, with no confinement and no documented threading contract.
isSameContent streams SHA-256 over two full APKs - the candidate and packages.apkFile()'s copy under /data/app - synchronously. awaitStampChange and resolveUid then poll packages.lastUpdateTime/uid, PackageManager binder calls, once a second. Nothing in this class hops to Dispatchers.IO, and the KDoc names no dispatcher the caller must supply.
quickbuild/docs/concurrency.md is explicit that the single session thread every effect runs on may not block: "A blocking call added here stalls the whole session." Hashing a 30 MB APK is hundreds of milliseconds in which the reducer, watcher batch delivery, and generation counter all stop.
Wrap isSameContent and the packages.* reads in withContext(Dispatchers.IO).
There was a problem hiding this comment.
Confirmed: no dispatcher hop anywhere in the class, and hashing two APKs on the session thread is exactly what concurrency.md forbids. Fixing in this stack: isSameContent and the packages reads move under Dispatchers.IO, and the KDoc states the confinement.

There was a problem hiding this comment.
MINOR: broadcasts.first { } throws when the flow completes without a match, breaking the "never throws" contract stated at line 177.
Flow.first(predicate) raises NoSuchElementException if the flow completes with no matching element. It runs in an async child of the coroutineScope, so that failure cancels the scope - taking stampChanged, the lastUpdateTime fallback that exists precisely for installers which never broadcast - and ensureInstalled throws instead of returning an InstallOutcome.
Unreachable today: nothing constructs ProxyAppInstaller yet, and whether it can fire depends on the app-side adapter that lands later. A callbackFlow closed on receiver unregister completes; a SharedFlow never does. Collecting inside a runCatching and degrading to InstallOutcome.Failed makes the KDoc true either way.
There was a problem hiding this comment.
Confirmed; the fallback dying with the scope would be the bad version of ironic. Fixing in this stack: the collection runs in runCatching and degrades to Failed, so the never-throws contract holds for either flow shape.

There was a problem hiding this comment.
MINOR: runCatching around a suspend call catches CancellationException, which REVIEW.md section 1 says to rethrow.
launchInstall is suspend, so a cancellation raised inside it is swallowed and reported as InstallOutcome.Failed(InstallCouldNotStart). Line 238 has the same shape.
No user-visible symptom today: the caller's own cancellation also cancels this coroutineScope, which re-raises on exit, so only a CancellationException originating inside launchInstall - its own withTimeout, say - is actually mislabelled. Worth fixing anyway because DaemonProcessClient in this same PR guards the identical pattern three times with catch (e: CancellationException) { throw e }, and a reader carries that expectation across.
try { launchInstall(apk) } catch (e: CancellationException) { throw e } catch (e: Exception) { false }.

Confirmed, at both sites. Fixing in this stack with the explicit CancellationException rethrow, matching the client's three guarded sites.

There was a problem hiding this comment.
MINOR: the unchecked mkdirs() turns "the scratch root cannot be created" into a false "not enough storage".
File.getUsableSpace() returns 0 for a path that names no partition, so when root cannot be created the next line reads 0 and this returns NotEnoughStorage(requiredMb = 100, availableMb = 0). prepare checks the shortfall first, so the user is told to free 100 MB on a device with plenty and nothing names the real fault - ScratchDirUnavailable only ever covers the per-project tree, never the root.
Narrow today: root is an app-private noBackupFilesDir subtree where mkdirs essentially always succeeds, and no production code calls this yet. QuickBuildScratchTest and its edge suite cover the blocked-tree case but not a blocked root.
if (!root.isDirectory && !root.mkdirs()) return ScratchDirUnavailable(root.absolutePath).
There was a problem hiding this comment.
Confirmed: an uncreatable root reads as a full disk with the wrong remedy on screen. Fixing in this stack with your one-liner, plus the blocked-root test the edge suite is missing.

There was a problem hiding this comment.
MINOR: the "exactly one transition means a lone shutdown" rule is asserted here but enforced nowhere.
markIntentionalTransition() is manual, and this class's start and shutdown deliberately never bump. So whether a session restart bumps the epoch once or twice is purely the session manager's convention. If it bumps once for a shutdown-then-start, a stale respawn landing on startEpoch + 1 reads the successor's live daemon as its own zombie and calls shutdown() on the single shared QuickBuildDaemon - leaving the successor holding DaemonReply.Ok while isRunning is false.
Not checkable in this PR; the session manager lands in PR 8. Stating the "a restart must bump twice" requirement in daemonEpoch's KDoc would give that PR's reviewer something concrete to check the manager against.
There was a problem hiding this comment.
Confirmed that the convention is load-bearing and unenforced. Adding the "a restart must bump twice" requirement to daemonEpoch's KDoc in this stack so the session-manager PR has a concrete contract to be checked against.

| file.delete() |
There was a problem hiding this comment.
MINOR: the delete-then-rename fallback can destroy the counter it exists to protect.
save's KDoc says the IOException is never swallowed because "losing it would let a later session reuse a generation". But the recovery path deletes the destination first: if delete() succeeds and the retry renameTo still fails, the previously good value is gone, the throw propagates, and the next load() returns null - a fresh session, which is exactly the reuse the doc rules out. The stale .tmp is left behind too.
Both edge tests put a directory at the target, where delete() fails harmlessly and no value was stored anyway, so the file case is unpinned. Reading the old value back before deleting (and restoring it if the retry fails) keeps the invariant the KDoc claims.
There was a problem hiding this comment.
Confirmed: the fallback can destroy the value whose loss the KDoc rules out, and the edge tests only cover the directory case. Fixing in this stack: on a failed retry we fall back to a direct write of the new value before throwing — non-atomic beats absent — and the stale tmp is removed; adding the file-at-target test.

NITPICK: shutdown() leaves scratchFsType reporting the dead daemon's filesystem.
start() clears it at line 108, with a comment about not stamping the previous session's filesystem onto the next one. shutdown() clears configured, process, and writer, but not this, so between a shutdown and the next successful configure QuickBuildDaemon.scratchFsType's "null before a successful configure" is false.

NITPICK: the pending flag is consumed before the isRunning check, so the "silent no-op" the KDoc promises for a daemon already down actually discards the request.
A TRIM_MEMORY_COMPLETE arriving in the window between a shutdown and the next configure clears pendingLowMemoryTeardown and returns; the daemon that comes up seconds later stays warm under the pressure that asked for the shrink. Self-healing in practice, since Android repeats trim callbacks while pressure lasts - but the doc and the code disagree.

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.

…request bound Important 1: unguarded asString on diagnostic severity/message threw out of compile() on object/array values -> primitive-guarded, degrading to ERROR / "unknown error"; covered by `a non-primitive severity or message degrades instead of throwing out of compile`.

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.
