ADFA-4930

PR 4 of 4 in the stack from docs/superpowers/plans/2026-10-14-adfa-4930-build-output-off-fuse.md, based on #2151, then #2150 and #2149. Merge those first. This PR's diff is nineteen commits plus five merges bringing in fixes from lower in the stack (#2151's sweep 34b6603 and marker 5f0afab, #2149's included builds 0b2f870, 315baa6: stage, #2149's experiment gate and #2151's no-follow tree deletion, and 86c4764: #2149's mixed-layout fix, already here as 55ebfde). 88a8f49 graduates the BUILD_OUTPUT_RELOCATION experiment that #2149 adds, deleting its entry, as this PR turns relocation on for everyone. Review by commit: 6d6e126 is renames only.

Why. The plan's validation gate has been run, and the results are posted on ADFA-4930. With build output in app storage, warm edit builds of a 288-source project took 48% less time on a Pixel 6 Pro. On a 1.9 GB itel A667L, clean builds took about 50% less, and small edits were unchanged because the CPU dominates there. Nothing got slower.

What it does

• Every sync relocates; there is no switch (ee5c6b3, after Hal Eisen's review). The "Relocate build output" preference, its strings and tooltip tag, the "move it back" banner wording, and the code that deleted a tree after a sync with relocation off are gone. Builds still follow the synced model, not the sync's intent.
• The relocation banner. Opening a project loads its cached model without syncing, so an existing project keeps building into its folder until its next sync. After initialization it shows "Sync to move build output to faster storage." with "Not now" and "Sync", once per screen. It is not offered once a sync has succeeded (recorded in the tree as relocating-sync after its model loads, so a sync that fails or is cancelled leaves the offer standing, 8f9392d) or when the tree cannot be written, so a project a sync cannot relocate doesn't get the banner after every sync and every open (55ebfde, Hal Eisen's second review). The text and buttons are short so Sync stays usable at 2x font scale; the shared banner's layout problem is ADFA-6572.
• A model counts as relocated when any project's build directory is in the tree (55ebfde). The rule looked at the root alone, so a root build script that sets its own build directory made builds run without the relocation flags while the model still put the subprojects' output in the tree: :app built into app/build, where Run and Export don't look.
• A Sync tapped while a build holds the Gradle slot (Quick Build's prebuild starts about 30 s after a project opens) used to be refused, and the failed initialization dropped the loaded model. The banner now defers it, says so, and offers it again once the build frees the slot. It waits on the slot itself (GradleBuildService.buildSlotBusy, d9cbebe): a build's listener can run before the build frees the slot, so a check made when the build flags drop could find it busy and never check again (Hal Eisen's review). The generic sync banner says to sync once the build ends.
• Old output in the project folder is removed, once (bcff8fa, Hal Eisen's review). After a project's first relocated initialization, OldBuildOutput deletes the build/ of each project the model relocated (only those: a project whose build script sets its own build directory keeps its build/, 5b25a22), and .gradle/ and .kotlin/ at the root and in buildSrc, records that in the tree once everything is gone (a deletion that fails is retried at the next initialization), and tells the user once: "Old build output was removed from the project folder. Export gets your latest build." A stale app-debug.apk where a file manager finds it misleads, and the copy doubles the space a project takes. Kept: buildSrc/.gradle/ and an included build's .gradle/ and .kotlin/ (still in use); a build folder that is or holds a module, or that the model still builds into; buildSrc/build/, since buildSrc is not in the model (714ef05); anything outside the project folder, checked on canonical paths so a linked module folder cannot lead out of it; symlinks, which are never followed. Skipped while a Quick Build session is live. A later terminal build's output is the user's to keep.
• Export covers App Bundles and plugins (15a83c9, Hal Eisen's review). Export APK becomes Export. For the selected variant it offers what was built: the APK, the App Bundle (outputs/bundle/<variant>/ under the module's build directory, as the model has no bundle listing), and a plugin project's .cgp, with a chooser when there is more than one. Each goes to the share sheet or to Download. Installing a built plugin deleted the .cgp it was given; the build's install now hands it a copy, so the plugin can still be exported. The action keeps its id and tooltip tag.
• The temporary plugin copy is always deleted, and a blocked offer is retried (5749dfb, CodeRabbit). Installing a built plugin copies it first; a failed install left that copy in filesDir/temp, and now installFromCopy deletes it (two tests fail without it). A relocation offer refused because a build held the Gradle slot is offered again when the build ends, only when a build is the reason. That wiring has no test and has not been run on a device.
• Output trees are deleted without following symlinks (5d95f18). Deleting a project's tree and the startup sweep (ADFA-4930: delete relocated output with its project, sweep orphans, Export APK #2151) used File.deleteRecursively, which follows a symlink to a directory and deletes what is inside it.
• Trees are keyed by the canonical project path, so every spelling of the path names the same tree. Existing keys are unchanged: the projects path CoGo uses is already canonical.
• build_completed gains relocated_output, for syncs and builds alike, so durations can be split by output location. It isn't on build_started, which can already exceed Firebase's 25-parameter limit.
• ARCHITECTURE.md describes where build output lives, and why code must read it from the synced model.

Verified

• Unit tests: BuildOutputLocationTest 30/30, OldBuildOutputTest 10/10, BuildExportTest 14/14, PluginCgpLookupTest 3/3, BuildCompletedMetricTest 4/4, RelocatedBuildsTest 4/4: 15 suites with the rest of services.builder, in one run, 0 failures (168 tests, at 714ef05). Each review-fix test fails without its fix:
  • the deferred offer: with a one-shot check of the slot, "expected: 1 but was: 0";
  • old output: with each guard removed in turn, the module-called-build, symlinked-folder and no-follow tests fail;
  • CodeRabbit's two findings (c61696f): before the fix, a module folder linking out of the project let find return its build/, and a failed deletion still wrote the marker, so it was never retried;
  • tree deletion: with deleteRecursively, the file a link in the tree points at is deleted;
  • Hal Eisen's second review (5b25a22, 55ebfde): find returned a user's lib/build beside a custom build directory; a model whose root alone sets its build directory was not relocated; and with the marker check removed, or both checks, a futile sync was still offered;
  • the third round (8f9392d, 714ef05): with the marker written as the sync started, a sync that never finished stopped the offer; and find returned buildSrc/build.
• Pixel 6 Pro (Android 17), at 714ef05 merged locally with current stage: a project whose broken build script made its sync fail had no relocating-sync afterwards; once fixed, Sync succeeded and only then wrote it. A project whose scripts set every build directory, its marker removed, was offered the banner; its Sync succeeded, wrote the marker, and the banner did not return.
• Pixel 6 Pro (Android 17), at 55ebfde merged locally with current stage (the phone had a stage build, so this avoids a downgrade), with two copies of a template project:
  • Only the root sets its own build directory, and the root's build/ holds a user file: the sync relocated (no banner), the user file survived, and Run built :app into the tree (main/app-…/outputs/apk/debug/app-debug.apk), nothing in app/build, and offered the install.
  • Root and :app both set their own build directory: after the sync, no banner, and none after leaving and returning to the app; the log says why (No relocation sync offered … one already ran), and the tree holds relocating-sync.
• Pixel 6 Pro (Android 17), at 15a83c9:
  • Settings > Build & Run has no "Relocate build output".
  • An existing project with build/, app/build/ (holding app-debug.apk), .gradle/ and .kotlin/ showed the relocation banner; Sync relocated it and logged Removed 4 old build output folder(s). The folder kept only sources, and the tree held the old-output-removed marker. With the marker deleted and two stale folders recreated, reopening removed them and showed the message.
  • Export with only Quick Build's proxy APK said so. After a run, it went straight to "Export APK". After Run Tasks :app:bundleDebug, it offered "APK" and "App Bundle (.aab)"; the bundle was at outputs/bundle/debug/app-debug.aab in the tree, and Copy to Download saved Build Apps Anywhere-debug.aab (3.9 MB).
  • Font scale 2.0: the Export chooser and "Export App Bundle (.aab)" dialog wrap their title and keep every option readable. 1.0 was fine too.
• Galaxy Note20 Ultra (Android 13), before the switch was removed: the banner at 2.0 kept a 108×52 dp Sync button; Sync tapped during Quick Build's prebuild was deferred, with no failed initialization, and offered again after it.
• Sites checked: isRequested() had three callers (the sync path, the banner, syncPending's default); all are gone. removeTreesOf had one caller passing keep, now gone. Only BuildOutputLocation.deleteTree in the stack deleted with deleteRecursively.
• Not checked on a device:
  • Exporting a plugin's .cgp. Both plugin projects on the Pixel failed to sync before relocation mattered: their buildscript needs guava-33.3.1-jre.jar, and the bundled Maven repo has only its .pom and .module. This is unrelated to ADFA-4930.
  • The removal message at 2x font scale. It uses the shared flash message, which wraps.

Docs and QA. The tooltip SQL attached to ADFA-4930 (tooltips-adfa-4930.sql, documentation.db in OfflineDocumentationTools) now covers Export only and deletes the removed switch's tooltip if an earlier version added it; checked on a copy of documentation.db, run twice. The ticket's Steps to QA cover the stack as it is now: no switch, old output removed once, and Export of APKs, App Bundles and plugins.

IMPORTANT

• ProjectHandlerActivity.kt:1253 - the tree is deleted under a live Quick Build session

MINOR

• ProjectHandlerActivity.kt:1250 - the guard and the deletion identify the project differently
• ProjectHandlerActivity.kt:308 - the deletion and deferral decisions have no unit test

NITPICK - 1 inline, not listed

Verdict. Computed: REQUEST_CHANGES, for one confirmed IMPORTANT. Posted as COMMENT because GitHub doesn't allow requesting changes on your own PR. REVIEW.md has no approve/request-changes rule, so the default table applied; CLAUDE.md moves a ticket to QA only with no critical, high or medium findings.

Stack. #2155 is the tip of #2149, #2150, #2151 and #2155 (base stage). Every claim was checked at eb1a366.

Earlier rounds. No earlier review comments on #2155; claude[bot] left only its manual-review notice.

Checked, no finding

• With relocation on for everyone, nothing outside the synced model should read <project>/build or .gradle/. A sweep of main sources at eb1a366 found none (PluginManager's "build" strings are service names), and plugins get APKs through ModuleContextResolver, which reads the model.
• isAvailable() has no callers left, and the new strings are in :resources.
• The deferral and re-offer run on the main thread, the deletion on Dispatchers.IO. A relocated sync can't start while this deletion runs: the banner that would start one is shown only after the deletion returns.

Already disclosed in the PR body, not re-posted: the generic banner's busy-build message isn't checked on a device, the shortened switch summary isn't checked at 2x, and the shared banner layout at 2x is ADFA-6572.

IMPORTANT

• GradleBuildService.kt:572 - relocated syncs report relocated_output=false

Stack. #2155 is the top layer of #2149 (d984d16) -> #2150 (b0648b8) -> #2151 (9a52063) -> #2155. Every claim was verified at the tip, 7fc4ccd.

Re-check of review 5552867168 (at eb1a366)

• F01, IMPORTANT, unused-tree cleanup under a live Quick Build session: fixed. shouldDeleteTrees returns false while the session is in any state other than Idle or Prebuilding (ProjectHandlerActivity.isQuickBuildSessionLive). Closing a project calls restartSession(), which tears the session down to Idle, so the next open's initialization deletes the tree as the KDoc says. Prebuilding is safe to exclude: it builds with the current, unrelocated model.
• F02, MINOR, guard and deletion keyed differently: fixed. treeFor keys by canonicalProjectLocation(), so the guard, sync, build and deletion all use one key, and removeTreesOf(keep = model's root buildDir) never deletes the model's tree. Canonical keying changes a key only where the canonical path differs from the spelling used (for example /sdcard, or /data/user/0 against /data/data). No released version created relocated trees, so nothing is orphaned. /storage/emulated/0/... is unchanged by inspection; not checked on a device in this review.
• F03, MINOR, untested Activity decisions: fixed. shouldDeleteTrees and shouldOfferDeferredSync are pure and covered (BuildOutputLocationTest, including the live-session and slot-busy cases). The deferral itself stays a direct isGradleSlotBusy() check, with no logic left to test.
• F04, NITPICK, no relocation flag in analytics: partly fixed. build_completed gains relocated_output for builds, and placing it on that event (8 parameters at most) instead of build_started (up to 28) is right. But syncs are recorded wrongly; see the IMPORTANT above. BuildCompletedMetricTest's new case fails without the change (no putBoolean), but it pins only the bundle, not the service's prepare-to-completion wiring, which is where the defect is.

Considered, not posted: relocatedBuildIds cannot grow without bound, since every prepared build and sync reaches notifyBuildSuccess or notifyBuildFailure and so dispatchBuildResult. Only a tooling-server crash mid-build leaves one small entry until the service is destroyed.

Verdict. REVIEW.md has no approve/request-changes rule, so the skill's default applied: a confirmed IMPORTANT computes REQUEST_CHANGES. It is posted as COMMENT because GitHub refuses that event on a self-authored PR. CLAUDE.md's QA gate (no critical, high or medium findings) is not met.

Coverage: this re-review was done as a direct pass at 7fc4ccd, without a separate /code-review run.

[davidschachterADFA]

MINOR

• GradleBuildService.kt:569 - the sync call site F05 fixed has no test pinning it

Stack: #2155 is the tip (949e076). Below it: #2151 (9a52063), #2150 (b0648b8), #2149 (d984d16, base stage). Every claim here was checked at 949e076.

Re-check of previous rounds (code read at 949e076, not from replies)

• F01 (IMPORTANT, tree deleted under a live Quick Build session): fixed. The cleanup is gated on shouldDeleteTrees(afterInit, modelRelocated, isQuickBuildSessionLive()) (ProjectHandlerActivity.kt:1251). Live means any state but Idle or Prebuilding (:1305-1307). The rule is pure (BuildOutputLocation.kt:175-179) and tested (a live Quick Build session keeps the tree it still uses).
• F02 (MINOR, spelling vs canonical path): fixed. treeFor keys the canonical path (BuildOutputLocation.kt:47-50). removeTreesOf(keep) skips the tree holding the model's build directory (:113-118), which the activity passes (ProjectHandlerActivity.kt:1258-1259). Both are tested.
• F03 (MINOR, untested decisions): fixed. shouldDeleteTrees and shouldOfferDeferredSync are covered in BuildOutputLocationTest.
• F04 (NITPICK, no relocation flag in analytics): fixed. relocated_output is on build_completed (BuildCompletedMetric.kt:25).
• F05 (IMPORTANT, relocated syncs reported as false): fixed.
  • relocatedBuilds.prepared(buildInfo, extraArgs) is unconditional (GradleBuildService.kt:569).
  • Both completion paths reach completed(): onBuildSuccessful (:641) and onBuildFailed (:666) go through dispatchBuildResult (:682).
  • The tooling server reports a sync's completion with its own ID (ToolingApiServerImpl.kt:234, and :151 on failure).
  • Only the call site lacks a test; that's the MINOR inline.

Considered, not posted

• Growth of the tracked set: an entry leaks only when prepareBuild ran and no completion is reported. That happens on an exception in executeTasks between doPrepareBuild and its try (ToolingApiServerImpl.kt:304-318), or on a tooling-server crash, one entry each for the service's lifetime. It's bounded in normal use.
• If the client's prepareBuild takes longer than the server's 30 s wait (ToolingApiServerImpl.kt:247-260), the build runs without the client's arguments while it is recorded as relocated. The metric would be wrong, but that build already lacks the init script and every IDE argument, a pre-existing problem below this PR.

Verdict: computed COMMENT (one MINOR, nothing above it). REVIEW.md has no approve/request-changes rule, so the default applied; the PR is self-authored, so COMMENT in any case. CLAUDE.md ties the move to QA to having no critical, high or medium findings; this round's only finding is in the MINOR, safe-to-merge tier.

📝 Summary

• Gradle syncs now relocate build output to app storage when the synced project model supports relocation. If an existing project has not relocated, the app offers a sync. Projects continue to use their synced model until they sync.
• The app defers a sync request while the Gradle build slot is busy. It can also defer the relocation offer until the slot is free. The relocation preference and experiment gate are removed.
• After a relocated initialization, the app removes eligible old project-folder output once. Cleanup avoids following symlinks and preserves output that may still be in use or belongs to a custom build directory.
• Export now supports APKs, App Bundles, and plugin .cgp files. The export action offers available outputs and uses each output’s extension and MIME type.
• Build-completion analytics now include the relocated_output field. ARCHITECTURE.md documents the relocated output directory.
• The author reports that 168 tests passed across 15 services.builder suites. The author also reports device checks on Pixel 6 Pro and Galaxy Note20 Ultra, including faster builds. These results are author-reported.
• Risk: Plugin .cgp export was not device-tested. The author reports that plugin projects could not sync because the bundled Maven repository lacked a required Guava JAR.
• Limitation: Builds launched outside the IDE are not redirected and may continue to write output into project folders.
• Risk: The cleanup message at 2× font scale and the deferred-offer activity wiring were not device-tested. The deferred-offer wiring also has no test.

Gradle syncs now prepare build-output relocation based on the synced model when the output tree can be prepared. The editor coordinates sync offers and one-time cleanup of eligible legacy output. The export action supports APKs, app bundles, and plugin files. The relocation preference and experiment gate are removed.

Merge Risk: Moderate · up to 42788

Under certain aliased project paths, automatic cleanup can delete project files. Fix the containment checks before merging.

Security architecture risk: Moderate · up to 0ab45

Automatic cleanup can reach outside the opened project through a linked parent directory and delete other app-accessible output. Activation requires a qualifying local filesystem layout and relocated initialization; no new privilege escalation is established.

Retained concerns

• High · security · inferred: New automatic cleanup does not preserve physical project containment through symlinked ancestors. For example, a linked buildSrc directory can make the fixed candidate buildSrc/build resolve to a real directory outside the project. Lexical startsWith checks and a final-component NOFOLLOW_LINKS check can admit it, after which traversal deletes the external directory's contents. Modeled project and active-build exclusions are also lexical. This requires the link to exist, the target to be app-writable, and cleanup to run without its completion marker; it is not a demonstrated privilege escalation.

Security review details

Security Blast Radius

• inferred — The containment failure can affect real build or cache directories outside the opened project that are reachable through candidate ancestors and writable with the app's existing filesystem authority. Exposure is local to that authority; the inspected path does not establish cross-device, cross-tenant, or operating-system privilege escalation.

Security Findings and Attack Paths

• inferred — A project filesystem layout containing a symlinked buildSrc ancestor can direct the new cleanup to an external real build directory. After relocated initialization, the lexical eligibility checks can accept that candidate and the deletion walk operates on its resolved target. Final-component and in-tree link protections do not block this path. This is a source-derived attack path, not a runtime-verified exploit.

Trust Boundaries and Controls

• observed — APK metadata path resolution and unsynchronized temporary-copy publication already existed at the merge base. The renamed utility preserves those mechanisms, including Quick Build proxy refusal and partial-file cleanup. They are pre-existing architecture conditions, not established new APK disclosure or publication concerns from this PR.

Resilience and Maintainability Implications

• inferred — The build slot serializes service-dispatched builds, but cleanup does not acquire that slot. Its Quick Build check precedes asynchronous deletion, leaving synchronization with every possible old-output writer unproven. The inspected evidence does not establish a reachable concurrent writer to retain a separate security concern.

Hardening Proposals

• proposed — Use resolved filesystem identity for root containment and protected-directory comparisons, reject candidates reached through unsafe ancestors, and preserve that identity through deletion. Canonical preflight checks alone should not be treated as protection against concurrent ancestor replacement.

Compare canonical paths for cleanup exclusions.

When dir is reached through a symlinked parent, canonicalOrNull(dir) can resolve to the same directory as a model path with another spelling. The current exclusions still compare lexical projects and inUse values with lexical dir, so a protected project or active build directory can pass both checks. Because NOFOLLOW_LINKS only checks the final candidate entry, cleanup may then delete that protected directory.

Keep the lexical paths for relocation detection and dir for the no-follow check. Canonicalize the protected paths and compare them with the canonical candidate. Fail closed if protected-path canonicalization fails.

Suggested fix

 		val projects = projectDirs.map { it.absoluteFile.normalize() }
 		val inUse = buildDirs.map { it.absoluteFile.normalize() }
+		val canonicalProjects = projects.map { canonicalOrNull(it) ?: return emptyList() }
+		val canonicalInUse = inUse.map { canonicalOrNull(it) ?: return emptyList() }
 		val relocated = projects.zip(inUse).filter { (_, buildDir) -> BuildOutputLocation.isRelocated(buildDir, tree) }
 		val candidates =
 			relocated.map { (projectDir, _) -> File(projectDir, "build") } +
 				listOf(".gradle", ".kotlin", "buildSrc/.kotlin").map { File(root, it) }
 		return candidates.distinct().filter { dir ->
-			canonicalOrNull(dir)?.startsWith(canonicalRoot) == true &&
+			val canonicalDir = canonicalOrNull(dir) ?: return@filter false
+			canonicalDir.startsWith(canonicalRoot) &&
 				Files.isDirectory(dir.toPath(), LinkOption.NOFOLLOW_LINKS) &&
-				projects.none { it.startsWith(dir) } &&
-				inUse.none { it.startsWith(dir) || dir.startsWith(it) }
+				canonicalProjects.none { it.startsWith(canonicalDir) } &&
+				canonicalInUse.none { it.startsWith(canonicalDir) || canonicalDir.startsWith(it) }
 		}

Update the cleanup candidate filter using canonicalOrNull: canonicalize project
and in-use paths and compare them against each canonical candidate, excluding
candidates when protected-path canonicalization fails. Keep lexical paths for
relocation detection and retain the NOFOLLOW_LINKS check on dir.
