…ookkeeping helper New, self-contained plumbing for deep-link support (no behavioral wiring yet): - DeepLinkRequest/PendingFileRequest/DeepLinkOpenRequest models and the URL parser for https://www.appdevforall.org/device/open/project/{name}[/file/{f}[/line/{n}[/column/{n}]]]. - PendingDeepLinkOpen, an in-memory handoff for the close-then-reopen continuation. - resolveWithinDirectory, a path-traversal guard for the attacker-controllable {filename} segment, mirroring the existing zip-slip pattern in AssetsInstallationHelper.extractZipToDir. Also guards against InvalidPathException from an embedded NUL byte (a %00 in the URL decodes to a literal NUL character, which java.nio.file.Path.resolve() throws on if uncaught). - recordProjectOpenedBookkeeping, extracted from MainActivity.openProject so a deep-link-triggered project switch gets the same Recents/analytics bookkeeping. - New error strings for the above. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
DeepLinkActivity is a UI-less trampoline holding the only <intent-filter> for https://www.appdevforall.org/device/open/project/... links. It parses the incoming URI, checks whether a project is already loaded (IProjectManager.getInstance().workspace), and routes to MainActivity (nothing open) or the live, singleTask EditorActivityKt (one is, reused via onNewIntent), then finishes itself immediately. Kept as a plain Activity (matching the existing SplashActivity precedent), not BaseIDEActivity, since it never calls setContentView and has no theming needs of its own -- this avoids a visible flash of MainActivity's real UI in the common case where the actual destination is the already-running editor. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Wires DeepLinkRequest handling into MainActivity's onCreate/onNewIntent: resolves the project name via findValidProjects, flashes an error if it doesn't exist, and otherwise opens it directly via openProject (bypassing GeneralPreferences.confirmProjectOpen -- an explicit link tap is itself a specific request to open project X, so re-confirming it is redundant friction). openProject gains an optional pendingFileRequest param that rides along in the EditorActivityKt intent extras for file/line/column navigation once the project finishes loading; all existing call sites are unaffected since it defaults to null. Also reindents a pre-existing over-length line in startWebServer() that the Spotless ratchet now covers as a side effect of touching this file (no behavior change). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…dlerActivity This is the activity that owns both the confirm-close dialog and the open editor tabs, so it makes the same-project/different-project decision itself rather than MainActivity: - onNewIntent resolves the project name and compares it against IProjectManager's current workspace/projectDirPath. Same project already open -> no-op project-wise, just navigate to the requested file. Different project open -> reuse the existing, unmodified confirmProjectClose() dialog. - confirmProjectClose/performCloseAllFiles gain an optional trailing onClosed callback (default null, so both existing call sites -- back-press and the sidebar "Close Project" action -- are byte-for-byte unchanged in behavior). onClosed only records the pending request (PendingDeepLinkOpen); it does not call startActivity synchronously, because doing so immediately after finish() risks the framework redelivering the new PROJECT_PATH to the dying singleTask instance via onNewIntent instead of spawning a fresh one. Instead onDestroy() drains it once the instance is guaranteed torn down. - applyDeepLinkFileRequest resolves the file/line/column request through resolveWithinDirectory (path-traversal guard) and reuses the existing openFileAndSelect/validateRange clamping -- no new clamping logic needed. - postProjectInit consumes a pending file request once a freshly opened project (cold open, or the tail of a close-then-reopen) finishes loading. Also fixes a pre-existing race in openFileAndSelect, found while testing the above on-device: EditorFeatures.validateRange mutates its Position arguments in place, and a freshly-created CodeEditorView's own async content-load pipeline calls validateRange/setSelection on that *same* Range instance separately from this function's own call. If this function's postInLifecycle callback ran first -- while the document was still the just-constructed empty one line -- it permanently clamped the shared Position down to (0,0) before the real content ever loaded, so opening a file that wasn't already in a tab at a specific line silently landed the cursor at line 1 instead. Fixed with a defensive copy so this function can no longer corrupt the shared instance regardless of which side runs first. This is existing, general-purpose API, not deep-link-specific -- no other caller happened to combine "brand-new tab" with a non-origin selection before.

…rification Placed at the top level so it mirrors the real eventual absolute path (https://www.appdevforall.org/.well-known/assetlinks.json) exactly, meaning relocating it to the actual website later is a literal file copy, not a rename. sha256_cert_fingerprints is left as a TODO placeholder -- the real value belongs to whoever controls the release signing key / Play Console and can't be filled in from source. Until that's live, autoVerify will fail Digital Asset Links verification and Android may show a disambiguation chooser instead of auto-opening the app; expected per the ticket's own framing ("we will move it to the website later").

📝 Walkthrough
WalkthroughAdded verified HTTPS App Links for project and file navigation. The change adds deep-link parsing, project resolution, editor handoff, lifecycle-safe state handling, recent-project bookkeeping, save-result propagation, and traversal-safe filesystem validation. ChangesDeep-link navigation
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to Deep-link project switching can be silently dropped during activity teardown, and file navigation can receive corrupted selection state; an additional process-death edge case may replay an older link.

Route on ActionContextProvider.getActivity() (tracks the live EditorHandlerActivity instance) instead of IProjectManager's workspace, which stays null for the whole duration of a Gradle sync even while EditorActivityKt is already open -- a link tapped mid-sync was mis-routed to MainActivity instead of the running editor. Found in code review of PR 1651.
Only handle a deep-link request when savedInstanceState == null, and clear the DeepLinkRequest extra afterward, matching postProjectInit's existing "don't reapply on a later config-change recreate" guard. Without this, a font-scale/dark-mode/locale change or a process-death restore re-triggered handleDeepLinkRequest and redundantly relaunched EditorActivityKt. Found in code review of PR 1651.
…p link confirmProjectClose() now dismisses any dialog it previously showed before showing a new one. Without this, two deep links for different projects arriving in quick succession (onNewIntent can fire repeatedly on the singleTask editor activity) could stack two confirm-close dialogs; confirming either one overwrote the single PendingDeepLinkOpen.value, silently dropping whichever project the user actually confirmed opening. Found in code review of PR 1651.
Replace repeated whole-list segments.indexOf(keyword) lookups with a cursor-based forward scan (indexOfFrom). indexOf always returns the first occurrence in the entire path, so a project name that happened to equal "line"/"file"/"column" was mistaken for that keyword later in the path, corrupting the file/line/column split. The cursor-based scan only matches occurrences at or after the previously consumed segment, so an already-consumed segment can never be re-matched. Adds a regression test for a project literally named "line". Found in code review of PR 1651.
The existing guard only normalized the path lexically, so a symlink physically present inside the project directory (e.g. from a git clone, which supports symlinks) pointing outside it was never detected -- the OS would follow it at actual file-open time. Add a third layer mirroring AssetsInstallationHelper.extractZipToDir's zip-slip guard: resolve the nearest existing ancestor of the requested path to its real, on-disk path via toRealPath() and re-verify containment. Skipped when the base directory itself doesn't exist, since there's nothing on disk to symlink-escape through. Adds a regression test with a real symlink pointing outside the base directory, and a companion test that a plain file inside a real base directory still resolves. Found in code review of PR 1651.

The doc still described the routing check as IProjectManager.getInstance().workspace, which the prior commit in this branch replaced with ActionContextProvider.getActivity() (see "Fix deep-link routing race in DeepLinkActivity").
recordProjectOpenedBookkeeping() called RecentProjectRoomDatabase.getDatabase(context, scope) directly instead of the RecentProjectDao already wired into Koin's coreModule (the same instance MainViewModel/RecentProjectsViewModel inject) -- a second, DI-bypassing acquisition path for the same singleton database, against ADR 0001/0006's "persistence is provided through Koin". recordProjectOpenedBookkeeping() now takes a RecentProjectDao parameter; both call sites (MainActivity, EditorHandlerActivity) inject it the same way they already inject analyticsManager. Found in architecture review of PR 1651.
DeepLinkActivity silently finished on an unparseable URI with no feedback to the user. Uses a Toast rather than the existing flashError helper -- this activity finishes immediately after, tearing down its window before a view-based Flashbar could ever render. Also adds msg_deeplink_scan_failed, used by the next commit. Addressed from inline PR review comments.
findValidProjects() can throw SecurityException (e.g. a storage permission revoked mid-session) inside the IO coroutine launched by MainActivity.handleDeepLinkRequest and EditorHandlerActivity.onNewIntent. Uncaught, that would crash the coroutine's scope instead of just failing this one deep link. CancellationException is rethrown; other failures are logged and reported to the user on the main thread. Addressed from inline PR review comments.
recordProjectOpenedBookkeeping()'s recentProjectDao.insert() ran with no error handling on ProcessLifecycleOwner's app-wide scope -- a transient Room/SQLite failure would crash the whole process instead of just failing to record one Recents entry. CancellationException is rethrown; other failures are logged. The in-memory project-open state (ProjectManagerImpl.projectPath, GeneralPreferences.lastOpenedProject) is set synchronously before the coroutine launches, so it's unaffected either way. Addressed from inline PR review comments.
resolveWithinDirectory()'s InvalidPathException/IOException catches intentionally discard the exception (the caller only needs null-or-not for attacker-controllable input) -- name the bindings "_" rather than "e" to make that explicit instead of reading as an accidentally swallowed exception. Addressed from inline PR review comments.
Two more cases for the indexOfFrom cursor-scan fix (045aa00): a project named "line" with no line suffix, and a project named "file". Both already passed before this commit -- this only adds coverage. A third proposed case, a project's file *path* itself starting with a segment literally named "line" (e.g. .../file/line/Main.kt), is not addressable by any segment-based fix: with no delimiter between the optional line/column suffix and the preceding filename, "the file path happens to start with 'line'" and "there's a real line/{n} suffix" are the same shape at the segment level. Not tested here -- a real fix would need a schema change (e.g. line/column as query parameters). Addressed from inline PR review comments.
Three related fixes in EditorHandlerActivity, all in the deep-link close-then-reopen path: - confirmProjectClose(): a generation token now guards the "Save and close" async callback. saveAllAsync completes asynchronously, so an older deep-link request's callback could still fire (contentOrNull stays non-null until onStop()/onDestroy(), well after finish()) after a newer request's dialog was already answered, overwriting PendingDeepLinkOpen.value with the superseded project. Only the request owning the current token is allowed to act. - Same callback no longer closes files unconditionally after "Save and close": saveAll()'s return value is gradleSaved (whether a build file changed), not "everything saved successfully". Now checks hasUnsavedFiles() and reports a failure instead of silently discarding unsaved changes on a failed write. - applyDeepLinkFileRequest(): require file.isFile, not just file.exists() -- a deep link resolving to an existing directory was passed straight to openFileAndSelect(). Addressed from inline PR review comments.
The previous fix (045aa00) searched for the line/column keywords forward from just after `file`, which still mismatched a file path that legitimately contains "line" or "column" as an early segment (e.g. a directory named "line") when a real trailing line/{n} suffix also follows it -- the forward search would still latch onto the first, coincidental occurrence. line/column are trailing modifiers, so match them from the end of the path backward instead: check for "column" immediately before the last segment, then "line" in whatever remains. This correctly keeps an early, coincidental "line"/"column" segment as part of the filename as long as a real trailing pair follows it. The one shape still unresolvable: a file path whose entire content is just the keyword plus one segment, with nothing else following (e.g. `file/line/Main.kt` alone) -- indistinguishable from a real line suffix with no delimiter in this URL scheme; documented as a known limitation with a locked-in test rather than silently misbehaving. Addressed from inline PR review comments.
…file Adds regression tests for the end-anchored line/column matching (df705c9): a file path segment literally named "line" or "column" is now preserved when a real trailing line/column suffix follows it, plus a test locking in the one remaining unresolvable shape (documented in the previous commit) so a future change doesn't alter it silently. Also converts this file's assertions from raw JUnit to Google Truth, per ARCHITECTURE.md's testing guidelines -- Truth is already available to :app's test source set transitively via testing:unit, so this is a same-file, no-build-config-change cleanup. Addressed from inline PR review comments.
…ight The generation-token fix (a451470) stops a stale "Save and close" completion from overwriting PendingDeepLinkOpen, but doesn't stop a second request from doing real damage while the first is still running: saveAllAsync iterates and mutates editorViewModel's file/editor state on a background coroutine, and "Close without saving" calls performCloseAllFiles synchronously on the main thread against that same state -- a second deep link answered with "Close without saving" while an earlier one's save is still in flight would race that save. confirmProjectClose() now drops a new request outright while closeInProgress is true (set for the duration of the async save), rather than showing a dialog whose buttons could trigger a concurrent mutation. This also protects the ordinary manual "close project" path against racing a deep-link-triggered save. Addressed from inline PR review comments.
…eepLinkOpen
Two small cleanups deferred from the original code review:
- MainViewModel.saveProjectToRecents() has had zero callers since the
deep-link work replaced it with recordProjectOpenedBookkeeping() --
delete it along with the now-unused RecentProjectDao constructor
parameter it existed only to serve.
- PendingDeepLinkOpen was a hand-rolled Kotlin `object` singleton,
against ADR 0006 ("no hand-rolled singletons -- prefer Koin"). Now a
Koin-provided `single`, injected into EditorHandlerActivity the same
way as analyticsManager/recentProjectDao. Same one-process-wide
instance either way; this just keeps it substitutable in tests and
out of the pattern the ADR asks new code to avoid.
AppModule.kt's diff also reformats the whole file to tabs -- it wasn't
previously tab-indented, and editing it at all pulls the whole file
under the Spotless ratchet (file-level, not line-level).
Addressed from deferred code-review findings.
…anning all
MainActivity.handleDeepLinkRequest and EditorHandlerActivity.onNewIntent
both did findValidProjects(PROJECTS_DIR).find { it.name == name } --
duplicated across both call sites, and findValidProjects itself
validates every project under PROJECTS_DIR just to find one by a
known name.
Adds findValidProjectByName(), the O(1) counterpart to
findValidProjects() for a caller that already knows the exact name,
and uses it at both call sites -- deduplicating the expression and
skipping the full-directory scan.
Addressed from deferred code-review findings.
applyDeepLinkFileRequest() had two copy-pasted 8-line blocks for line/column parsing, differing only in the target var, the error string resource, and which PendingFileRequest field was read. Collapsed into one zeroBasedOrFlashError() helper. Also folds in a stray PendingDeepLinkOpen.value -> pendingDeepLinkOpen rename left over from 9741df7's Koin conversion. Addressed from deferred code-review findings.

Data loss / lost-work fixes in the project-switch and deep-link flow: - DeepLinkActivity: drop FLAG_ACTIVITY_CLEAR_TOP when routing to MainActivity. ActionContextProvider.getActivity() can miss a live, backgrounded EditorHandlerActivity (a documented gap), and CLEAR_TOP would then destroy that live editor to clear the path to MainActivity, discarding unsaved work with no prompt. - EditorHandlerActivity: MainActivity.openProject's bookkeeping call mutates the process-wide projectDirPath global to the NEW path before EditorHandlerActivity ever compares against it, so its same-project/different-project detection could never actually fire a genuine switch - tapping a different project from Recents while one was already open showed no confirm-close and silently kept displaying the old project. Threads the pre-mutation path through a new PREVIOUS_PROJECT_PATH intent extra instead. - EditorHandlerActivity.onDestroy: gate the pending-close-callback drain on isFinishing. A non-finishing recreate (a config change EditorActivityKt doesn't declare, or "Don't keep activities") could land while a confirm-close dialog was still showing and silently confirm/discard the project it was showing. - EditorHandlerActivity.saveAllAsync: bail before invoking runAfter if the activity is finishing/destroyed. Wrapping the whole save in NonCancellable (needed so the write itself survives teardown) also made the Main-dispatcher runAfter hop survive teardown, touching a dying window/cleared ViewModels. - EditorHandlerActivity: don't drain a pending file request until the project is actually ready (workspace != null) - draining unconditionally left postProjectInit's deferred retry with nothing once a mid-sync request's apply attempt silently failed. - EditorHandlerActivity.restoreIntentToStayingProject: reset the switch-capture fields before the blank-path bail, not after, so a blank projectDirPath doesn't leave them stuck for the rest of the instance's life. - MainActivity: track deep-link consumption via a field persisted in onSaveInstanceState, not by mutating the Intent's own extra. A process-death recreate redelivers the original, unmutated launch Intent, so the old signal didn't survive it and the same request force-reopened a project the user had already navigated away from. Other confirmed bugs: - BaseEditorActivity.preDestroy: guard BuildOutputProvider/plugin snippet-listener teardown on a new didCompleteLiveOnCreate flag, matching the sibling guards EditorHandlerActivity/ ProjectHandlerActivity already have. A doomed duplicate instance whose onCreate bailed early never registered as their owner, so its teardown was wiping out a live sibling's registration instead. - EditorHandlerActivity.checkForExternalFileChanges: recompute areFilesModified after markAsSaved(). It's a cached flag only refreshed as a side effect of a successful per-file write, so it could stay stale-true after an external-change reload, permanently blocking GitBottomSheetFragment's save-before-git-action gate. - ZipUtils.unzipFile: reject a `..` path *segment*, not a substring (a filename like "notes..txt" was wrongly rejected); skip extracting over an existing symlink instead of aborting the whole archive (a user's legitimately symlinked gradlew broke Gradle wrapper install). - PathTraversal.resolveWithinDirectory: use Files.exists(_, NOFOLLOW_LINKS) in the ancestor walk. Plain Files.exists() follows symlinks, so a dangling one read as absent and the walk stepped past it instead of rejecting it. Cleanups: - Extract RecentProjectRepository so MainActivity/EditorHandlerActivity no longer inject RecentProjectDao (a Room data source) directly, per ARCHITECTURE.md's UI -> ViewModel -> Repository -> data source layering. - EditorHandlerActivity: use Range's existing copy constructor instead of hand-rebuilding one from raw Positions (equivalent today). - Correct a KDoc claiming MainActivity's exported="true" is "required for the launcher" - SplashActivity holds the actual MAIN/LAUNCHER filter; MainActivity has none, which is exactly why it's the actual attack surface the surrounding paragraph describes. - Remove .well-known/assetlinks.json and .well-known/README.md: now served from an R2 bucket via a Cloudflare Worker (#1693), making these repo-committed copies dead weight. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The intent-filter only matched www.appdevforall.org, so a hand-typed or shared apex link (no www) opened in a browser instead of the app. Per hal-eisen-adfa's review: both hosts already serve an identical, verified assetlinks.json via the Cloudflare Worker from #1693 with no redirect, so this is a second <data> element plus accepting the same host in DeepLinkRequest.parse's own re-validation (DeepLinkActivity is exported, so that re-check - not the manifest declaration alone - is what actually gates a request).

…ember every consumed request Two findings from the review, both real. The liveness guard in saveAllAsync skipped runAfter wholesale, which threw away the non-UI half of a callback's work. Its own comment names the case: a confirmed "Save and close" arms a process-wide pending deep-link switch that has to outlive this instance, so with the guard in place the requested project never opened and nothing was logged. runAfter is invoked unconditionally again, and the two callbacks in this file guard what actually needs a live window -- the same shape GitBottomSheetFragment's _binding check already had. Save-and-close gets an explicit teardown branch that still performs the handoff, mirroring the contentOrNull == null branch beside it. A single consumedDeepLinkRequest slot let a first link re-fire after process death: consuming link B leaves the task's launch Intent still carrying A, and that is the Intent a recreate is handed, so A no longer matched and reopened its project. Every consumed request is remembered now, in a new ConsumedDeepLinkRequests kept outside the activity so this bookkeeping is testable -- three separate lifecycle paths depend on it. Capped at 32 with oldest-first eviction so a looping sender cannot grow the saved Bundle. 7 tests on the new class, all of which fail against single-slot semantics.

…silent This is the branch that used to lose a confirmed deep-link project switch, and it is invisible from the UI -- the only symptom was a project that never opened. An on-device attempt to exercise it could not trigger it: the phone declines to destroy the activity while the app holds a foreground service, so the line is also how we will know if it ever fires in the field.

… dots resolveWithinDirectory rejected any relative path containing ".." as a substring, so a deep link to a legitimately named file -- notes..txt, a..b/c.kt -- failed with no explanation. The old test called this an acceptable trade-off on the grounds that project files never need consecutive dots; the sibling guard in ZipUtils.unzipFile had already concluded the opposite for the same pattern, and it is right. Nothing is given up. Only a literal ".." segment can name a parent directory, so the per-segment check catches every traversal the substring check did, and the normalize + startsWith + toRealPath layers below remain what actually enforce containment. The traversal-rejection tests pass identically before and after. Percent-decoding happens in Uri.pathSegments before this function runs, so an encoded traversal arrives as a literal ".." segment and is caught; a double-encoded one arrives as the filename "%2e%2e", which cannot name a parent. Both now have tests. The three copies of this containment algorithm are still three copies. That is a separate change: this one has no Android dependency and `app` already depends on `common`, so it can be shared rather than mirrored by hand.

NonCancellable protects saveAllAsync's body only once it has started running. A launch on the IO dispatcher can still be queued when onDestroy() cancels the activity's scope, in which case the body never starts, runAfter never runs, and a confirmed deep-link project switch is lost -- the same loss as the liveness guard this PR already removed, through a narrower window. The application scope from AppModule has no such window. The activity is retained for the duration of the save, which is what NonCancellable already implied. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
MainActivity was exported="true" while declaring no intent-filter of its own -- SplashActivity holds MAIN/LAUNCHER -- so nothing outside the app ever needed to launch it. With deep-link support it became the component that accepts a parsed DeepLinkRequest as an Intent extra, which any co-installed app could send directly: DeepLinkActivity's URI validation bypassed, an arbitrary project forced open and an arbitrary file inside it navigated to, with no user interaction and no permission. The confirmation gate handleDeepLinkRequest relied on for exactly this reason is not one: GeneralPreferences.confirmProjectOpen defaults to false, so on a default install askProjectOpenPermission never runs and the open is immediate. That preference is a user convenience, not a security boundary, and its KDoc now says so. The boundary is the manifest. DeepLinkActivity is same-app, so the real handoff is unaffected; EditorActivityKt, the other target, already defaulted to not exported. DeepLinkTargetsNotExportedTest pins both halves: neither handoff target is exported, and DeepLinkActivity itself stays exported -- "fixing" that one would turn every deep link into a silent no-op. Confirmed to fail with exported="true" restored. The manifest is stored with CRLF line endings and Spotless does not enforce LF on it, so the edit preserves them; a text-mode rewrite silently converts all 390 and buries this two-line change in a 786-line whole-file diff. Found in review of PR #1651.

The other findings from this review pass — the OOBE bypass past |
Both of DeepLinkActivity's targets sit beyond SplashActivity and OnboardingActivity, which are the only things enforcing the terms, the permissions, the JDK and SDK install, the low-storage check and the x86 exit. A link on a fresh install -- or after Clear Data -- therefore opened the editor with no toolchain and no permissions, where builds and file access fail for reasons the user cannot connect to anything they did. On an x86 device it made the app reachable at all, past a guard that deliberately calls finishAffinity() and exitProcess(0). The link is now dropped when setup is incomplete: the user is told, and sent to SplashActivity, which decides what they actually need. Dropped rather than deferred, deliberately -- carrying a request through an onboarding that takes minutes and may not finish is a lot of machinery for a rare case. Nothing here re-decides storage or ABI; those stay SplashActivity's, so there is one place that knows the launch order. The readiness rule itself moves to isIdeSetupComplete() rather than being copied. OnboardingActivity had it privately and now calls the shared one; a second copy would let the two disagree about what "ready" means, and the copy that disagrees silently is the one that skips a gate. DeepLinkSetupGateTest covers both halves: the predicate is false with no toolchain installed, and a link arriving in that state routes to SplashActivity and finishes. Without the gate the same test lands on MainActivity, which is the bug. 308 app tests pass. Found in review of PR #1651.

…he one loaded The setup gate asked IJdkDistributionProvider.installedDistributions, which returns an empty list until loadDistributions() has run -- and that runs inside the loader coroutine IDEApplication launches on Dispatchers.Default. On a cold start an Activity's onCreate reaches the main thread first, so the gate answered "not set up" on a device that was, discarded the link, and told the user to finish a setup they had already finished. That is the ticket's first requirement, broken by the guard meant to protect it. It now reads the directory JdkUtils.findJavaInstallations scans -- one stat and one listing, cheap on the main thread, and true as soon as the bootstrap has unpacked regardless of what has loaded. An empty lib/jvm still counts as not installed. OnboardingActivity keeps its own, stricter predicate rather than sharing this one. It can afford to wait for a JDK the provider has loaded and validated -- it calls loadDistributions() itself when the list is empty -- and must not hand over to MainActivity until the toolchain is really usable. Two different questions, so two predicates, each with the reason recorded. Sharing them would have made this gate's cold-start problem onboarding's problem too, in the other direction: onboarding would hand over as soon as a directory existed. The existing test could not have caught this: Robolectric has no JDK, so asserting the gate returns false passed either way. The new test builds the cold-start state instead -- a toolchain on disk with nothing loaded -- and fails against the provider-based check. 310 app tests pass. Found in review of PR #1651.
This PR and #1736 both ship

| this PR | app/src/main/java/com/itsaky/androidide/utils/PathTraversal.kt |
Same package, same top-level resolveWithinDirectory, so both compile to com.itsaky.androidide.utils.PathTraversalKt. app depends on common, and app's own source shadows it.
Because the paths differ, git reports no conflict on this file — the merge that matters is the one it performs silently. I put both copies in one tree and compiled :app:compileV8DebugKotlin: BUILD SUCCESSFUL, no duplicate-class error, no warning. Then asserted behaviour:
resolveWithinDirectory(dir, ".") returned /tmp/which-copy9345358656880404820
expected null, but was:</tmp/which-copy...>
common's copy returns null there. This one returns the base directory, which proves both that app's copy wins and that the hole is live.
What this copy is missing
It is an earlier draft of the same code, without three fixes #1736 made:
- No
resolved == baseguard.".","./"and"./."resolve tobaseDiritself. This is the hole @itsaky-adfa reported on ADFA-5257: Share one path-containment check instead of two divergent copies #1736, fixed there inf364ccca6. Note this PR's own suite containsempty relative path is rejected instead of resolving to baseDir itself— it states the invariant it doesn't enforce for the dot spelling. if (!Files.exists(base)) return resolved.toFile().Files.existsreturning false conflates "absent" with "cannot be determined" (EACCES on a parent), so layer 3 is skipped and containment silently degrades to lexical. ADFA-5257: Share one path-containment check instead of two divergent copies #1736 splits these:NoSuchFileExceptionskips, any otherIOExceptionrefuses.- No log when a filesystem failure is turned into a
null, so a disk problem is reported to the user as a traversal attempt.
For EditorHandlerActivity.kt:2455 — the {filename} segment of a deep-link URL, i.e. the attacker-controllable input this work exists to guard — that means the hardened check sits unused in common while the draft handles the request.
The fix
Delete both files:
app/src/main/java/com/itsaky/androidide/utils/PathTraversal.kt
app/src/test/java/com/itsaky/androidide/utils/PathTraversalTest.kt
No coverage is lost: I diffed the two suites by test name and common's is a strict superset — all 13 cases here plus 8 more (symlink loops, a base that cannot be resolved, a symlink planted after construction, the normalizes to baseDir case). Both call sites keep working unchanged: EditorHandlerActivity already imports com.itsaky.androidide.utils.resolveWithinDirectory, and ProjectValidations is in that package.
I have not pushed this, because the deletion only compiles once common's copy exists — so this PR has to land after #1736, or merge it in. I stopped rather than merge #1736 here, for the reason below.
Separately: this PR no longer merges cleanly to stage
GitHub still shows MERGEABLE, but that is stale. stage moved to 02eeccc38 (ADFA-5125, #1742) which rewrote 1087 lines of GitBottomSheetFragment.kt; this PR rewrites 873 lines of the same file. A test merge gives 4 conflict blocks spanning 1078 lines — two independent refactors of one file. Resolving that means deciding what this PR's Git-fragment changes are for, which is yours to make, not mine to guess at. It is also the only one of the thirteen open PRs that conflicts with stage today.
Happy to push the two deletions the moment #1736 is on stage, or now if you would rather this PR stack on it.
Conflict was GitBottomSheetFragment.kt, where stage's ADFA-5125 (#1742) rewrote 1087 lines of the same file this branch had reindented. Almost all of this branch's 457/416-line change to that file was formatting: 77/35 ignoring whitespace, and the residual was ktlint output -- trailing commas, argument wrapping, brace restructuring -- from the "Reindent GitBottomSheetFragment.kt and IEditorHandler.kt to tabs" commit. #1742 has since reindented the file itself, so that work is redundant. Resolved by taking stage's version and re-applying the one semantic change this branch made: the saveAllAsync callback in checkUnsavedChangesAndProceed now bails when _binding is null (the callback outlives onDestroyView, and action() dereferences binding) and requires areFilesModified() to be false before running a git action, flashing save_failed otherwise -- succeeded only means saveAll() did not throw, so a silent per-file write failure would otherwise commit a tree whose edits never landed. Audited the resolution rather than trusting it: of the 44 lines present on this branch and absent from the merge result, 41 are in the merge base -- pre-existing code #1742 refactored -- and the other 3 are a ktlint suppression and two trailing commas. No behaviour from this branch is lost. Verified: spotlessApply is a no-op beyond the merge, :app:compileV8DebugKotlin succeeds, and the branch's own 56 tests pass (DeepLinkRequest 25, PathTraversal 13, ConsumedDeepLinkRequests 7, ProjectValidations 5, DeepLinkSetupGate 4, DeepLinkTargetsNotExported 2).

high — correctness: Environment.PREFIX is still null on the cold start this gate exists for
PREFIX is a plain public static File (common/src/main/java/com/itsaky/androidide/utils/Environment.java:57) assigned only in Environment.init() (:146). Both call sites of init() run inside an unawaited coroutineScope.launch(Dispatchers.Default) in IDEApplication — DeviceProtectedApplicationLoader.load() from IDEApplication.kt:187, and CredentialProtectedApplicationLoader.load() from :91 on unlock.
DeepLinkActivity.onCreate runs on the main thread as soon as Application.onCreate returns, so on a cold start it routinely wins that race. File(null, "lib/jvm") doesn't throw — it yields the relative path lib/jvm, isDirectory is false, and a fully set-up device gets msg_deeplink_setup_incomplete and is bounced to SplashActivity with the link discarded.
That is the same class of failure the KDoc above says this function was written to avoid. Moving off IJdkDistributionProvider fixed the provider-load race; Environment.init is a second race of identical shape, on the same coroutine, and the disk read still depends on it. Cold start is also the primary deep-link case — tap a link with the app not running — so this isn't an edge.
Two details that widen the window:
PREFIXis notvolatile, so even afterinit()completes onDispatchers.Defaultthere is no happens-before edge guaranteeing the main thread observes the write.&&short-circuiting inisIdeSetupCompleteis the only thing keeping this from an NPE —ANDROID_HOMEis assigned in the sameinit()(Environment.java:173) and is dereferenced on the next line.
Why the tests don't catch it. the setup predicate is false when no toolchain is installed passes for the wrong reason: Robolectric never runs Environment.init either, so PREFIX is null and the answer is false by accident rather than because no toolchain is on disk. The two tests that would expose it — the setup predicate is true from disk alone, with no distributions loaded and an empty lib-jvm directory does not count as installed — both assign Environment.PREFIX by hand, which is precisely the step a real cold start has not done yet. The uncovered case is "toolchain on disk, PREFIX still null": it should answer true and answers false.
Suggested fix — one line, no race. init() derives the prefix from constants, not from anything runtime: ROOT = new File(DEFAULT_ROOT) then PREFIX = new File(ROOT, "usr") (:145-146), and Environment.DEFAULT_PREFIX is already a public static final String holding that same path (:44). So:
val jvmDir = File(Environment.DEFAULT_PREFIX, "lib/jvm")Same directory, available at class-load time, independent of whether the loader coroutine has run. mkdirIfNotExists only matters for writers; this is a read.
A regression test for it would assert isIdeSetupComplete() is true with the JDK on disk and Environment.PREFIX left null — i.e. the field never assigned, rather than assigned to a temp folder.

high — correctness: a deep link into the already-open project is silently dropped while that project is syncing
The comment right above says the request "must stay armed for postProjectInit's deferred retry once that sync completes, or it's lost for good". Nothing in this branch arms it.
Walk the case !confirmCloseInProgress && !projectReady — same project, mid-sync, which is the exact state the comment is written for:
else if (projectReady)is false, soapplyDeepLinkFileRequestnever runs.- the
if (fileRequest != null && (confirmCloseInProgress || projectReady))block below is also skipped — that's the only place in the branch that touches the intent, and it removes the extra rather than storing one. - there is no
putExtra(PendingFileRequest.EXTRA_KEY, ...)anywhere on this path. The two places that do arm it areBaseEditorActivity.kt:738(cold open) andEditorHandlerActivity.kt:2047(restoreIntentToStayingProject);onNewIntenthas no equivalent.
So fileRequest lives only in the local variable and dies with the call.
What the user sees afterwards is worse than nothing happening. onNewIntent's carry-forward at :2247-2251 has already re-armed the previous, still-unconsumed request onto the intent. Since the newer request never displaces it, postProjectInit finds the stale one when the sync completes and navigates there — the deep link appears to work, at the wrong file. And no error is flashed on either outcome, unlike the confirmCloseInProgress arm which at least shows msg_project_close_in_progress.
The removal block's own comment names this exact hazard — "leaving it in place would have postProjectInit silently jump back to that stale target once the current sync completes, discarding this newer navigation" — but its guard excludes the one state where the newer navigation has nowhere else to live.
Fix shape: in the not-ready, not-closing case, store the request instead of dropping it:
} else if (projectReady) {
fileRequest?.let { applyDeepLinkFileRequest(it) }
} else {
fileRequest?.let { intent.putExtra(PendingFileRequest.EXTRA_KEY, it) }
}which also makes the removeExtra below redundant for this arm, since the put has already superseded the carried-forward value.
Worth a test: same project open, workspace == null, onNewIntent with a deep link naming file B while a carried-forward request for file A is on the intent — assert postProjectInit lands on B.
