WalkthroughAdds the core Quick Build live-reload pipeline. The changes define reload decisions, build orchestration, asset packaging, proxy deployment and recovery, generation persistence, session messages, and telemetry. JVM tests cover concurrency, deployment, parsing, retention, and save coalescing. ChangesLive-reload build pipeline
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to Quick Build deployment can fail for certain asset layouts, interrupt the editor during restart, lose an active proxy connection, or report deployment success for a different generation. These behaviors should be resolved before merge. Sequence Diagram(s)sequenceDiagram

- Around line 57-60: Update packageAssets to deduplicate the mapped entries by
their normalized relative path before writing the ZIP and constructing
relativePaths. Use the rel value produced by relativeAssetPath as the uniqueness
key, while retaining one corresponding file for each path so ZipOutputStream
receives no duplicate entry names.

- Line 7: Update the E2eTimeline entry in the README to remove the nonexistent
parse API, leaving the format() reference and the remaining timeline description
unchanged.
In
`@quickbuild/core/src/main/java/org/appdevforall/cotg/quickbuild/service/deploy/PayloadDeployer.kt`:
- Around line 248-259: Update the reconnect-generation branching in
PayloadDeployer so every reconnectGeneration value unequal to generation is
treated as a mismatch, including newer generations; retain the existing success
path only for exact equality and preserve the outdated-baseline rebuild outcome
for mismatches.
- Around line 209-234: The restart handling around ProxyAppLauncher.launch must
not foreground the proxy app when userInitiated() is false. Defer relaunch until
an explicit Quick Build action, or use a non-foregrounding restart mechanism,
while preserving the existing reconnect and failure behavior for user-initiated
deploys.
In
`@quickbuild/core/src/main/java/org/appdevforall/cotg/quickbuild/service/deploy/QuickBuildHostService.kt`:
- Around line 147-154: Update disconnect and the registration flow around
HostBinder.enforceCaller and ProxyAppConnections so each successful connect
records a per-registration caller identity or token, then disconnect validates
that identity before invoking clearDeathWatch and connections.onDisconnected.
Ignore stale disconnects from superseded proxies, while preserving disconnect
behavior for the currently registered proxy.
In
`@quickbuild/core/src/main/java/org/appdevforall/cotg/quickbuild/service/telemetry/MetricsReporting.kt`:
- Around line 19-24: Update report to rethrow CancellationException before
logging, and catch only ordinary reporting failures rather than all Throwable
values; ensure JVM Error types and coroutine cancellation propagate while
regular metrics sink exceptions still produce the existing warning.
In
`@quickbuild/core/src/test/java/org/appdevforall/cotg/quickbuild/domain/reload/LiveReloadOrchestratorTest.kt`:
- Line 14: Remove the unused report import from LiveReloadOrchestratorTest,
leaving the remaining imports and test code unchanged.
In
`@quickbuild/core/src/test/java/org/appdevforall/cotg/quickbuild/domain/telemetry/E2eTimelineGroupsTest.kt`:
- Around line 57-65: Update the singles list in `each HostSpans field alone
makes the group non-empty and counts toward the total` to include
`E2eTimeline.HostSpans(queueMillis = 7)`, covering the queue-only `isEmpty` and
total behavior alongside the existing fields.

Java ZipOutputStream putNextEntry duplicate entry ZipException official documentation
💡 Result:
In Java, the ZipOutputStream.putNextEntry(ZipEntry e) method throws a ZipException if a ZIP format error occurs [1][2]. While the official documentation does not explicitly detail every possible condition for a "duplicate entry" error in the text of the method description, it is a well-established behavior of the implementation that attempting to add an entry with a name that already exists in the ZIP archive will trigger this exception [1][3]. This behavior occurs because the ZIP file format maintains a central directory, and duplicate entry names are generally considered invalid or ambiguous within a single ZIP file structure. When you call putNextEntry with an entry name that has already been processed and closed in the current stream, the underlying implementation detects this conflict and throws a ZipException to indicate the violation of the ZIP format requirements [1][4]. To avoid this, ensure that your application logic tracks the names of entries already added to the ZipOutputStream (e.g., using a Set) and checks for duplicates before calling putNextEntry [1][2].

Deduplicate asset-relative paths before writing the ZIP.
packageAssets accepts a Collection<File>, and relativeAssetPath normalizes each path. Two lexical aliases can produce the same ZIP entry name. ZipOutputStream.putNextEntry rejects the duplicate and can abort asset packaging. Deduplicate by rel before writing the ZIP and constructing relativePaths.

Not taking it. assetRoots() returns exactly one root, so two live files cannot map to the same rel via different roots, and changedFiles is a union of two Set, so identical paths collapse before they arrive. The lexical-alias mechanism is ruled out at both producers: relativeAssetPath normalizes both sides, and the only two path sources emit canonical paths.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Do not foreground the proxy app for a save-triggered restart.
When userInitiated() is false, this path still calls ProxyAppLauncher.launch(). The launcher resumes the proxy app task and interrupts the editor. PayloadDeployerTest lines 91-108 confirms this behavior.
Defer the relaunch until an explicit Quick Build action, or implement a restart path that does not foreground the app.

Not taking it. The test cited as evidence is titled "the deferred focus steal" and its KDoc pins this deliberately: a restart cannot finish without the process coming back, so suppressing the relaunch needs a decision about what a half-restarted app does. The proposed gate is the exact one that KDoc rules out, and it is worse than today, because the restart has already killed the process, so deferring the relaunch leaves the user's app silently dead until they tap Quick Build. The underlying UX question is live and owned by the team, not by this PR.

Require the exact deployed generation after restart.
A reconnectGeneration greater than generation reaches the success branch. This returns BuildOutcome.Success(generation) although the proxy app reported a different generation.
Treat every reconnectGeneration != generation result as a mismatch, unless the protocol explicitly supports advancing to a newer generation here.

Not taking it. CoGo is the only minter of generations, and GenerationTracker.adoptAtLeast is called with the installed baseline at every session start, so the generation just deployed is always the highest in existence and the greater-than case cannot occur. The one-character hardening is harmless if we want it; the stated failure does not happen.

IMPORTANT: this is the only union that bypasses unionPendingLocked, so a failed build silently drops the sticky Gradle verdict.
Every other merge into pending (onFilesChanged, onCancelRequested, onProxyAppRebuildFailed, onBaselineUntrusted) goes through unionPendingLocked, which latches stickyInvalidation when the union collapses to Unknown. This one uses bare +.
Concrete sequence:
onFilesChanged(ChangedFiles.Unknown)(or a save followed byonDaemonReplaced) starts build ADFA-319 - Welcome Screen Test #1 withflight.batch == Unknown--classify(Unknown)isCodeAndResources, so nothing latches.- Mid-build the user edits
app/src/main/AndroidManifest.xml.onFilesChangedsetspending = Known({manifest}); the union staysKnown, solatchInvalidationLockednever fires, andmaybeStartBuildLockedreturns early because a build is in flight. - Build ADFA-319 - Welcome Screen Test #1 fails. Here:
pending = Unknown + Known({manifest})=Unknown, and becauseunionPendingLockedis skipped,stickyInvalidationstays null -- the manifest path is gone. newSavesArrivedMidBuildis true, so the follow-up runs withroute = classify(Unknown) = CodeAndResources: it compiles, relinks, deploys and reportsSuccesswith the manifest change never absorbed.
That is exactly the silent-staleness stickyInvalidation exists to prevent -- LiveReloadOrchestratorTest pins the onFilesChanged and onBaselineUntrusted routes into the collapse (lines 2093 and 2120) but not this one, so the gap is untested.

IMPORTANT: t3 is stamped after the retention copy, so the headline save-to-live number includes disk I/O the user never waited for.
retain() copies the dex, the relinked arsc and the assets zip into the staging dir and writes meta.json before clock() is read on the next line. Those copies are the full payload -- on a low-end device with the scratch tree on FUSE-backed emulated storage (the 52x case E2eTimeline.scratchFsType documents) that is tens to hundreds of milliseconds.
The comment right below claims t3 is the moment "reportReloaded came back from the recreated activity's onResume, so the new code is live", and BuildOutcome.Success(generation, liveAt - loopStartedAt) is the duration shown to the user. Both are inflated by retention, and because no HostSpans field covers it the excess lands silently in E2eTimeline.unaccountedMillis -- the residual this PR added to keep unmeasured work visible.
Read the clock first, then retain:

Confirmed: retention runs inside the timed span on both confirmed-deploy paths, and no span covers it, so it lands in the unaccounted residual. One correction to the magnitude: the retention dir lives under the scratch work dir, which is required to be on app-private storage, so the copies are ext4, not FUSE — we estimate low tens of milliseconds on a warm code edit rather than hundreds. Fixing in this stack by reading the clock before retain at both sites; it also keeps timings comparable with the pre-retention pass the published numbers came from.

SHOULD FIX: notifyBuildStatus 20 lines below catches broad Exception with the note that "binder proxies can throw beyond RemoteException", but the payload call here catches only RemoteException and IOException.
A SecurityException, a parcel-side RuntimeException, or anything else the generated stub raises escapes deploy() entirely. LiveReloadExecutor's contract says the executor must not throw, so it surfaces as BuildOutcome.InfrastructureFailure rather than DeployResult.Failed -> BuildOutcome.DeployFailure. That is not cosmetic: LiveReloadOrchestrator.recordFailureLocked only tallies InfrastructureFailure, so two identical throws in a row escalate to a full Gradle proxy app rebuild, while the same failure routed as a deploy failure would not.
Either widen this to the same Exception catch notifyBuildStatus uses, or say in a comment why the payload call is held to a narrower set.

SHOULD FIX: the table is missing two of the seven files this PR adds to the folder -- ProxyAppPriorityHold.kt and RetainedPayloadStore.kt.
Both are load-bearing (the freezer hold is what keeps saves from timing out after ~66 s, and the retained store is what a below-deployed reconnect replays instead of forcing a rebuild), and the folder README is the map a reader uses to find them. CLAUDE.md asks for docs updated in the same change as the code.

…edates the rebuild A filesystem that truncates mtimes to whole seconds can stamp a save made just after a proxy app rebuild started with an mtime just before it. The echo split then folded it into the absorbed set and onBaselineReset dropped it: the edit never built and nothing said so. An mtime on a whole-second boundary is now taken as truncated and must predate the rebuild start by 2 s (the FAT step) to absorb. A flat margin on every mtime would instead strand a genuinely pre-start save on every filesystem, because the watcher's debounce (150 ms quiet, 1 s cap) puts such a save's mtime within a second of the start; four of the existing F4 echo tests go red under it. A file the rebuild already holds keeps the exact cutoff, since its arrival is the echo the split exists to absorb.

… an outdated runtime awaitDisconnect only watched the connection registry, which clears when linkToDeath fires. A loaded device can deliver that notification after the 5 s disconnect wait, and the deployer then reported a current runtime that had exited as one that "predates restart support" and forced a multi-minute Gradle rebuild. On timeout the channel now pings the registered binder. A ping is a transaction, so it fails as soon as the process is gone; the channel then clears the registry as the late notification would and reports the runtime gone, and the restart path proceeds to relaunch. A runtime that still answers keeps the outdated-runtime verdict.

… an outdated runtime awaitDisconnect only watched the connection registry, which clears when linkToDeath fires.

…icy, the binder deploy channel, stage-cost telemetry Co-Authored-By: Claude Fable 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01Kj9YeCDHGp9DU8LPtfWJ7W
…icity, deploy teardown - Swallowed linkToDeath failure -> a binder dead at connect is reported as an instant death and never registered, so deploys fail fast as NotConnected instead of timing out with the freezer hold kept on a dead package (tests: "a binder that is dead at connect is not left registered", "a dead binder's stale connect retry does not clobber a live registration"). - Non-atomic connect watch/registration -> registration and death watch are one @synchronized step, and death delivery shares the lock, so the watched binder and the registered target can never disagree and a death cannot slip between link and registration (test: "a death delivered while connect is registering still clears the target"; wiring: "a reconnect moves the watch, and firing it clears the registration"). - Restart payload retained with hot-swap metadata -> a confirmed restart deploy clears the retained set instead of retaining it, so a reconnect catch-up can never hot-swap over the live restart-sensitive component and falls back to the forced rebuild (test: "a confirmed restart deploy clears the retained payload instead of retaining it"). - endSession leaving an in-flight deploy to time out -> endSession routes through onDisconnected, whose Disconnected report answers the waiter deterministically (test: "ending the session answers a deploy awaiting its verdict as Disconnected"). - Adjacent minor: disconnect() now unlinks the death watch, so no stale recipient outlives a graceful disconnect (test: "a graceful disconnect unlinks the death watch").

…efore retention, broad binder catch, doc corrections Akash's 08-31 review of #1718, all seven items: - LiveReloadOrchestrator: the failed-build merge goes through unionPendingLocked, so an Unknown batch collapsing over a mid-build invalidating edit latches the Gradle verdict instead of erasing it. Test pins the collapse (verified red: the manifest edit rode the fast daemon path). - PayloadDeployer: t3 is read before the retention copy (hot swap) and the retention clear (restart), keeping post-deploy bookkeeping out of the timed save-to-live span. Ordering tests verified red against the old order at both sites. - DeployChannel: the payload send rethrows CancellationException and degrades any other exception to DeployResult.Failed, mirroring notifyBuildStatus's binder rationale; escape would also dodge the not-connected escalation. Test verified red. - deploy/README: table gains ProxyAppPriorityHold and RetainedPayloadStore. - ComponentInfo: header rewritten to the declares-one-always-restarts rule; supertypes marked carried-but-unread. - ClassHeader: KDoc aligned with the README's "currently unused". - E2eTimelineRecorder: false class-header-parse claim dropped. quickbuild:core tests green (both flavors). Also: plain-language pass over the comments added by these fixes Co-Authored-By: Claude Fable 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01STCsdMzx9daNBcqMN424Ci
Non-blocking items from Akash's 2 September round; the PR itself is approved. - Two sibling docs still stated a "restart closure" rule the policy does not implement. Both now say what DeployPolicy does - a declared restart-sensitive component restarts every code-bearing deploy - and the stale-helpers notice says which deploys can still reach it. #1718 (comment) - An ask is no longer reported as AWAITS_DEPLOY without checking that a deploy is actually still coming. Every path that declines to start a build leaves the work queued, so this changes no outcome today; it stops a future early return from dropping the tap silently instead. #1718 (comment) - installPriorityHold releases the hold it replaces, which is what its KDoc already promised. #1718 (comment) - Dropped an unused import ktlint's substring match cannot see. #1718 (comment) - RetainedPayloadStore's KDoc claims the last deploy's own parts rather than a cumulative set, which is what retain writes. #1718 (comment) Co-Authored-By: Claude Fable 5.1 <[email protected]> Claude-Session: https://claude.ai/code/session_017o3nPrBbGi2XYkMUGavG2A
…edates the rebuild A filesystem that truncates mtimes to whole seconds can stamp a save made just after a proxy app rebuild started with an mtime just before it. The echo split then folded it into the absorbed set and onBaselineReset dropped it: the edit never built and nothing said so. An mtime on a whole-second boundary is now taken as truncated and must predate the rebuild start by 2 s (the FAT step) to absorb. A flat margin on every mtime would instead strand a genuinely pre-start save on every filesystem, because the watcher's debounce (150 ms quiet, 1 s cap) puts such a save's mtime within a second of the start; four of the existing F4 echo tests go red under it. A file the rebuild already holds keeps the exact cutoff, since its arrival is the echo the split exists to absorb.

absorbEchoesLocked treated a held ChangedFiles.Unknown as "every file is already held" and skipped the granularity margin for all of them. After an external Gradle build untrusted the baseline (pending = Unknown) and a rebuild started, a .kt saved 0.5 s into the rebuild on a 1 s-mtime filesystem stamped a whole second before the start, was absorbed, and onBaselineReset dropped it - the edit was never built. An Unknown held set names no file, so nothing proves an arrival is an echo; only an enumerated held set keeps the exact cutoff. New test pins the Unknown case; a second new test pins the margin's upper bound (an 8_000 stamp against a 10_000 start absorbs), which with the existing 9_000 case fixes the constant at 2 s.

…be deleted retain() and clear() discarded deleteRecursively's result, so a partial delete could leave a readable meta.json behind - contradicting this store's own "replaced wholesale by every retain" contract. Both now go through a private purge() that empties meta.json before the recursive delete and returns the delete's result. The order is the load-bearing part: unlinking a name needs write permission on the directory, rewriting a file's bytes needs it only on the file, so a truncated meta.json still fails load() closed in the case where the delete cannot proceed at all. load() keys off the metadata alone, so once that is unreadable the rest of the tree is inert. retain() checks the result into its existing catch; clear() warns when parts survive. Not propagated to callers: both are post-deploy bookkeeping on the success path, with the payload already live in the app. Failing a build for a retention housekeeping error would turn a cheaper-recovery optimisation into a build failure, and the documented fallback - the catch-up rebuild - still happens.

…ir cannot swallow it
purge() emptied meta.json inside a runCatching and then returned the delete's
result, so a store whose metadata write AND recursive delete both failed left
meta.json intact and readable. load() parsed it and handed a superseded
baseline's bytes to a reconnect re-send - the one thing this store exists not to
do. Emptying the metadata and unlinking it need different permissions, which is
why the class treated them as independent, but a read-only meta.json under a
read-only directory refuses both at once.
The invalidation is now recorded beside the directory when neither half took, and
load() refuses a set carrying that marker. The marker needs only the parent, which
retain() must be able to write anyway to rename its staging dir into place, and it
is cleared as soon as a purge removes the set.
Without the fix the new test reports:
value of: load()
expected: null
but was : RetainedPayload(generation=1, metadataJson={"gen":1}, ...)
Also corrects the purge() KDoc, which claimed a failed delete always leaves the
set unreadable (board task t-jwpRC46uvGrH). It now states the one case that is
still only logged - a store whose whole tree has gone read-only, where there is
nowhere left to record anything - and clear()'s warning no longer asserts an
invalidation it cannot guarantee.

Part 6/11 of the stacked split of #1669 (requested by Akash). Base: feature/ADFA-4128-qb-05-core-detection. Stack overview + review mechanics: PR 1 (#1713). Terms are defined in quickbuild/README.md (lands in PR 1).
Gets a finished build into the running app by the fastest route that is still correct, and keeps a record of where the time went.
