Summary

Opening a .cgp (plugin) or .cgt (template collection) file from outside CoGo — e.g. an email attachment — now prompts to install it, instead of doing nothing (ADFA-4934).

  • New ExternalFileInstallActivity with a VIEW intent-filter for .cgp/.cgt (both content:// and file://, typed and untyped — see manifest comments for why each variant is needed).
  • .cgp files are copied to a temp file and forwarded into the existing PluginManagerActivity install flow (conflict/signature-check, overwrite confirmation) — reused verbatim, no new plugin UI.
  • .cgt files get a new TemplateCollectionRepository, since no import/conflict backend existed for template collections before: validates the archive via the existing ZipTemplateReader, and on a filename collision offers overwrite / rename & install / ignore, using the archive's filename as its identity (templates.json has no collection-level name field).
  • The .cgt install/conflict/rename dialogs are built in Jetpack Compose per ADR 0009 (caught by an architecture-review pass before opening this PR) — first Compose UI in the app module itself, reusing floating-window's FloatingTheme for visual consistency with the IDE's XML theme.
  • Mechanical prep: introduced a shared PLUGIN_ARCHIVE_EXTENSION constant, replacing ~7 duplicated .cgp string literals.

Test plan

  • :app:testV8DebugUnitTest — full suite passes, including 18 new tests (ExternalFileInstallViewModelTest, TemplateCollectionRepositoryImplTest)
  • :app:assembleV8Debug builds and installs cleanly
  • Verified end-to-end on a physical arm64 device (Galaxy Note20 Ultra, Android 13):
    • "Open with" chooser correctly lists Code on the Go for both .cgp and .cgt
    • Fresh .cgt install → confirm dialog shows filename + parsed template names → installs, template picker sees it without restart
    • Colliding .cgt → all three paths (Overwrite / Rename & Install / Ignore) verified
    • .cgp → forwards into Plugin Manager's existing install dialog; invalid file correctly rejected with no crash and no broken entry
    • No crashes anywhere in logcat across the session

Two things were found and fixed during on-device testing (not caught by unit tests or a clean build):

  1. A rendezvous effect channel could silently drop the first UI effect on a fast synchronous path — switched to a buffered channel.
  2. dumpsys package showed a mimeType on any <data> tag applies to the whole <intent-filter>, not just that tag, breaking untyped file:// matching — split into dedicated typed/untyped filters (see manifest comments).

Consolidates the ".cgp" literal duplicated across ~7 sites into a single
constant, mirroring the existing TEMPLATE_ARCHIVE_EXTENSION. Prep work for
the external file-install feature, which needs a canonical way to
recognize .cgp files.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Adds a VIEW intent-filter (ExternalFileInstallActivity) so opening a
.cgp/.cgt attachment (e.g. from email) prompts to install it, instead of
doing nothing.

.cgp files are copied to a temp file and forwarded into PluginManagerActivity,
reusing its existing install/conflict/signature-check flow verbatim rather
than duplicating it.

.cgt files get a new TemplateCollectionRepository, since no import/conflict
backend existed for template collections before now: it validates the
archive via the existing ZipTemplateReader, and on a filename collision
offers overwrite / rename-and-install / ignore (the ticket's requested UX),
using the archive's filename as its identity since templates.json has no
collection-level name field.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
On-device testing (dumpsys package) showed a mimeType on any <data> tag
applies to the WHOLE intent-filter, not just that tag - so a single filter
mixing content's mimeType-bearing variant with file's mimeType-less variant
silently broke matching for untyped file:// intents (confirmed via
`pm query-activities`: 0 matches before this fix, 2 after).

content:// keeps a single filter (the OS resolves an implicit type for it
regardless), but file:// now gets two dedicated filters, one typed and one
not. Verified end-to-end on a physical device: the "Open with" chooser lists
Code on the Go for both .cgp and .cgt, and the full install/conflict-resolve
flow (fresh install, rename, overwrite, invalid-file rejection) works.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
ADR 0009 requires new dialogs to be Compose, not MaterialAlertDialogBuilder
- caught by an architecture-review pass before opening the PR. Enables
Compose in the app module (mirroring floating-window's setup) and rewrites
the three .cgt dialogs (install-confirm, name-conflict, rename) as
composables, reusing FloatingTheme so they stay visually consistent with
the IDE's XML theme. The .cgp path is untouched: it still forwards into
PluginManagerActivity's existing (pre-ADR) dialog rather than duplicating
it.

Fixed two things surfaced by this rewrite:
- compose-rules ktlint caught the ViewModel being forwarded into a nested
  composable; fixed via state hoisting (a plain suspend lambda instead).
- The rename dialog's suggested name no longer visually clips its first
  character - that was a View EditText auto-scroll artifact from
  selectAll(), gone now that Compose's TextFieldValue sets the cursor
  position explicitly.

Re-verified end-to-end on the physical device: fresh install, rename,
overwrite, and the .cgp forwarding path all work with the new dialogs.

📝 Walkthrough
  • Added support for installing external .cgp plugin and .cgt template collection files.
  • Added typed and untyped content:// and file:// intent filters for lowercase and uppercase extensions.
  • Added .cgt validation, conflict detection, overwrite, rename, ignore, retry, and cleanup flows.
  • Added Compose dialogs using FloatingTheme.
  • Added path-traversal protection, safe staging, failed-write preservation, and rename fallback handling.
  • Improved cold-start, process-recreation, duplicate-event, cancellation, and temporary-file cleanup handling.
  • Added shared archive-extension and FileProvider utilities.
  • Added regression tests for installation safeguards, URI handling, collisions, cleanup, and retry behavior.
  • Builds and physical-device verification completed successfully.
  • Known limitation: Filename-less content:// URIs cannot match manifest filters.
  • Risk: The exported activity processes external file intents. URI validation and temporary-file cleanup must remain correct.
  • Risk: Confirmed overwrite replaces an existing template archive. The reserved core archive remains protected.

Walkthrough

The change adds external .cgp and .cgt installation through exported intents and Compose UI. It adds template collection storage, source-aware plugin cleanup, shared FileProvider utilities, archive-extension centralization, flashbar support, and Robolectric coverage.

Changes

External Archive Installation

Layer / File(s) Summary
Shared archive extension
composite-builds/.../constants.kt, app/src/main/java/.../actions/file/*, app/src/main/java/.../handlers/*, app/src/main/java/.../repositories/*, plugin-manager/.../PluginManager.kt
The shared archive extensions replace hardcoded plugin checks across discovery, validation, installation, editor handling, and file actions.
Template collection repository
app/src/main/java/.../repositories/TemplateCollectionRepository*.kt, app/src/test/java/.../repositories/TemplateCollectionRepositoryImplTest.kt
The repository inspects archives, detects collisions, validates names and paths, installs collections, reloads templates, and reports feature availability.
External archive intake and UI
app/build.gradle.kts, app/src/main/AndroidManifest.xml, app/src/main/java/.../activities/ExternalFileInstall*.kt, app/src/main/java/.../viewmodels/ExternalFileInstallViewModel.kt, resources/src/main/res/values/strings.xml
The exported activity accepts archive intents. The ViewModel validates and stages files. The Compose screen handles confirmation, conflict, rename, retry, success, and error states.
Source-aware plugin installation
app/src/main/java/.../ui/models/PluginManagerUiState.kt, app/src/main/java/.../viewmodels/PluginManagerViewModel.kt, app/src/main/java/.../activities/PluginManagerActivity.kt, ARCHITECTURE.md
Plugin installation distinguishes content URIs from local files, suppresses duplicate forwarded dialogs, and applies source cleanup across installation outcomes.
Shared FileProvider routing
common/src/main/java/.../FileProviderUtils.kt, app/src/main/java/.../dnd/*, app/src/main/java/.../utils/{ApkInstaller,IntentUtils}.kt, common/src/main/java/.../{FeedbackEmailHandler,FeedbackManager}.kt
FileProvider authority and URI creation move to shared context utilities used by drag-and-drop, installers, intent helpers, and feedback attachments.
Flashbar synchronization and support
common/src/main/java/.../Flashbar{Activity,}Utils.kt
Flashbar success and error helpers can await display completion with a bounded timeout and foreground-activity handling.
Validation coverage
app/src/test/java/.../viewmodels/ExternalFileInstallViewModelTest.kt, app/src/test/java/.../repositories/TemplateCollectionRepositoryImplTest.kt, common/src/test/java/.../utils/FileProviderUtilsTest.kt
Tests cover archive validation, feature availability, forwarding, conflicts, retries, cleanup, sanitization, unique-name generation, repository safety, and FileProvider authority generation.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 8bfe6

The new external archive installation flow still has unsafe overwrite, cancellation, retry, and request-lifecycle paths that can lose template collections, bypass conflict handling, or disrupt an active install. Merge should be blocked until these correctness and data-preservation issues are addressed.

Rethrow CancellationException and catch only expected validation or I/O failures.

Code review (PR #1682) findings, mechanical/data half:

- The app's FileProvider authority string ("<packageName>.providers.fileprovider")
  was duplicated inline across 7 call sites (IntentUtils, ApkInstaller,
  FileDragStarter, DragAndDropExtensions, FeedbackManager, FeedbackEmailHandler,
  and the new IDEFileProvider helper) - a rename would have needed 7 manual
  updates with no compiler check. Consolidated into common/FileProviderUtils.kt,
  shared across app and common (which can't depend on app's IDEFileProvider).

- Manifest: android:pathPattern has no case-insensitive mode, so a .CGP/.CGT
  (uppercase) attachment previously never matched. Added uppercase variants,
  and combined .cgp/.cgt into 3 shared filters (down from 6) since every
  <data> tag within one filter already had to share the same mimeType-bearing
  shape. Documented, as an explicit known limitation, that a sender whose
  content:// Uri path never carries the filename (e.g. some email providers'
  attachment Uris) can't match a pathPattern-based filter regardless of type -
  the alternative (a pathPattern-less mimeType="*/*" filter) would register
  this app as a candidate for every file-view intent on the device, which is
  a worse tradeoff than missing those senders.

Verified on a physical device: `pm query-activities` now matches both cases
of both extensions via content:// and file://, typed and untyped.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Behavioral half of the review findings:

- "Delete installation file after install" silently did nothing for a .cgp
  forwarded from ExternalFileInstallActivity: DocumentsContract.deleteDocument()
  only works against a real SAF DocumentsProvider (it calls a special
  METHOD_DELETE_DOCUMENT via ContentProvider.call(), returning true
  unconditionally unless an exception is thrown), and our own IDEFileProvider
  doesn't implement that call. Now dispatches to plain contentResolver.delete()
  for our own authority (confirmed via decompiling FileProvider.class that its
  delete() correctly deletes the mapped file) and keeps deleteDocument() for
  real picker-sourced Uris. Forwarded installs also no longer show the
  checkbox at all - there's no source worth optionally keeping, since it's
  our own hidden temp copy - so it's now always cleaned up.

- Cold-start race: isPluginManagerAvailable()/isTemplatesFeatureAvailable()
  could run before IDEApplication's async setup finishes if the OS
  cold-starts straight into ExternalFileInstallActivity. Both are now polled
  briefly (up to 3s) instead of failing on the first check.

- Two process-death drops: ExternalFileInstallActivity and PluginManagerActivity
  both only acted `if (savedInstanceState == null)`, which also (incorrectly)
  skips a process-death-recreated instance - the one case that most needs to
  reprocess the restored intent, since it lost all in-memory state. Replaced
  with idempotency tracked inside each ViewModel instance (survives rotation,
  resets on process death, matching real recreation semantics).

- Rename dialog: an in-flight async name suggestion could clobber whatever
  the user had already started typing.

- installCollection()'s own collision check was case-sensitive, bypassing
  findExistingCollision()'s case-insensitive matching - both now share one
  lookup.

- A failed template install used to delete the temp file and close the
  screen, forcing the user to re-open the original attachment to retry.
  Failure now just shows an error and leaves the current dialog open.

- Wired ShowTemplateNameConflict.info into the conflict dialog instead of
  dropping it silently (it now shows contained template names, matching the
  fresh-install dialog).

- Hardened temp/session file naming from timestamp to UUID (collision risk
  under rapid concurrent opens), moved UriFileImporter.getDisplayName() onto
  Dispatchers.IO (was running unguarded on Main), and stopped conflating
  CancellationException with real copy failures (now always cleans up the
  partial file either way, and doesn't show a bogus error for an ordinary
  cancellation).

- installCollection() also tried File.renameTo() as an "atomic move" - this
  round-tripped through on-device testing: it silently fails on this device
  even within the app's own private storage (a well-known Android
  unreliability), so a real .cgt install regressed to always failing until
  a copy+delete fallback was added back.

Re-verified end-to-end on a physical device after each fix: fresh install,
rename, overwrite, and the delete-checkbox's absence for forwarded installs
all confirmed working; the retry-after-failure behavior was directly
triggered and observed holding the dialog open.

Ran /code-review on this PR and fixed everything it found (2 more commits):

Real correctness bugs:

  • "Delete installation file after install" silently did nothing for a .cgp forwarded from ExternalFileInstallActivityDocumentsContract.deleteDocument() only works against a real SAF DocumentsProvider; our own IDEFileProvider isn't one, so it returned true unconditionally without deleting anything. Now dispatches to contentResolver.delete() for our own authority (verified via decompiling FileProvider.class) and no longer even shows the checkbox for forwarded installs — there's no source worth optionally keeping.
  • Cold-start race: isPluginManagerAvailable()/isTemplatesFeatureAvailable() could run before IDEApplication's async setup finished if the OS cold-started straight into the trampoline activity. Now polled briefly instead of failing on the first check.
  • Two process-death drops (ExternalFileInstallActivity and PluginManagerActivity both gated on savedInstanceState == null, which is wrong for exactly the recreation case that most needs to reprocess). Replaced with per-ViewModel-instance idempotency.
  • installCollection()'s collision check was case-sensitive, bypassing findExistingCollision()'s case-insensitive matching.
  • A failed template install used to delete the temp file and close the screen, forcing a full re-open of the original attachment to retry. Now the dialog stays open and just shows an error.
  • Rename dialog: an async name suggestion could clobber in-progress user input.
  • ShowTemplateNameConflict.info was computed but silently dropped instead of shown.

Manifest gaps:

  • .CGP/.CGT (uppercase) never matched — pathPattern has no case-insensitive mode. Added uppercase variants and consolidated 6 filters down to 3.
  • Documented (as an explicit, accepted limitation) that a sender whose content:// Uri never carries the filename in its path — some email providers' attachment Uris look like this — can't match regardless; the alternative (a pathPattern-less mimeType="*/*" filter) would register this app for every file-view intent on the device, which is worse.

ADR 0009 violation, fixed before any of the above: the three new .cgt dialogs were MaterialAlertDialogBuilder (View-based); ADR 0009 requires new dialogs to be Compose. Rebuilt them as composables, reusing floating-window's FloatingTheme.

One regression caught by re-testing on-device after the review fixes: installCollection() tried File.renameTo() as an "atomic move" — this silently fails on the test device even within the app's own private storage (a known Android renameTo() unreliability), so template installs would have always failed. Fixed with a copy+delete fallback.

Re-verified the full flow on a physical device after every fix: fresh install, rename, overwrite, retry-after-failure, and the delete-checkbox's absence for forwarded installs.

Rethrow coroutine cancellation.

runCatching captures CancellationException in both repository operations. A canceled caller can receive a failure Result instead of cancellation.

Catch CancellationException explicitly and rethrow it. Catch only expected recoverable I/O and archive parsing failures for the Result path.

As per coding guidelines: “In coroutine code, catch exceptions inside the launching coroutine, rethrow CancellationException, and avoid broad catches where narrower types suffice.” Based on learnings: “prefer narrow exception handling that catches only the specific exception type reported in crashes ... instead of a broad catch-all.”

Use the shared plugin archive extension.

The .cgp literals duplicate the archive-extension contract. Build this suffix from PLUGIN_ARCHIVE_EXTENSION so intake, validation, and temporary-file handling cannot diverge.

As per coding guidelines: “Reuse existing helpers, extract duplicated logic, replace repeated magic values with named constants, and maintain loose coupling with one owner per concern.”

Correctness:
- TemplateCollectionRepositoryImpl: refuse to install/overwrite the
  reserved "core" basename so an external .cgt named "core" can no
  longer delete the bundled default templates archive; wrap
  findExistingCollision() in try/catch like its siblings.
- ExternalFileInstallViewModel: guard confirmTemplateInstall() against
  a double-tap race; give the Flashbar entrance animation time to
  render before Finish tears the activity down.
- Add uiMode/locale/fontScale/density to both activities'
  configChanges so a config change mid-dialog can't strand the
  forwarded-install flow behind a one-shot guard that already fired.
- PluginManagerViewModel: clean up the forwarded source file on
  install failure, a conflict abort, or the user cancelling either
  confirmation dialog - not just on success.

Reuse/simplification:
- Forward a .cgp as a plain file path instead of a minted FileProvider
  Uri, so PluginManagerViewModel can install directly from it instead
  of copying it a second time; drops the now-redundant
  IDEFileProvider.getUriForFile wrapper.
- Replace Uri-authority sniffing in deleteSourceDocument() with an
  explicit PluginInstallSource (ContentUri vs LocalFile) from the
  caller.
- Extract a shared LastValueGate for the two "run at most once per
  forwarded value" guards that were previously duplicated with
  slightly different shapes.
- Dedupe the template-name joinToString() formatting between dialogs.
- Wire long-press help into ExternalFileInstallScreen.kt via a small
  reusable Compose/idetooltips interop helper, per ADR 0009/REVIEW.md
  guidance for a first Compose screen ahead of the ADFA-4381 bridge.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
- Use collectAsStateWithLifecycle() instead of collectAsState() per
  ADR 0009's explicit guidance, adding the lifecycle-runtime-compose
  dependency it calls for (the app had none yet).
- Update ARCHITECTURE.md's PluginManagerUiEvent.InstallPlugin example
  to match the PluginInstallSource change from the prior commit.

Match the archive extension case-insensitively.

findCollisionFile filters with file.extension == TEMPLATE_ARCHIVE_EXTENSION. This comparison is case-sensitive. The base-name comparison on the next line is case-insensitive, so the two checks disagree. The manifest accepts uppercase .CGT files, so a stored MyTemplates.CGT is not detected as a collision and a second, case-differing collection can be created.

🐛 Proposed fix
 			templatesDir
-				.listFiles { file -> file.extension == TEMPLATE_ARCHIVE_EXTENSION }
+				.listFiles { file -> file.extension.equals(TEMPLATE_ARCHIVE_EXTENSION, ignoreCase = true) }
 				?.firstOrNull { it.nameWithoutExtension.equals(baseName, ignoreCase = true) }

Announce the long-press help action to accessibility services.

combinedClickable receives an empty onClick and no labels. Two effects follow. First, the element becomes a focusable click target that performs no action. Second, screen readers cannot discover the long-press help action, because onLongClickLabel is not set.

Pass an onLongClickLabel from a cd_* string resource that describes the action. If the tooltip is the only action, keep the empty onClick but label the long press.

As per coding guidelines: "Content descriptions must use cd_* string resources, describe the action rather than the icon, and be state-aware for toggles."

Addressed the remaining CodeRabbit findings in f896c47:

Fixed:

  • Path traversal via targetBaseName in TemplateCollectionRepositoryImpl.installCollection (reject separators/./.., plus a canonical-path containment check).
  • Data-loss risk on overwrite: the incoming archive is now staged fully under templatesDir before the existing file is deleted.
  • PluginManagerViewModel.installPlugin no longer converts cancellation into an install-failure toast; cleanup runs under NonCancellable.
  • Switched the two new files' logging to SLF4J (ExternalFileInstallViewModel, TemplateCollectionRepositoryImpl), per REVIEW.md.
  • Added FileProviderUtilsTest, path-traversal + preserve-existing-on-failure tests, and switched ExternalFileInstallViewModelTest to use tempFolder.root.

Dismissed (with reasoning in-thread):

  • "Hostless file:// URIs are rejected by host=\"*\"" - verified on-device this is incorrect for the standard file:///path form (empty-string authority, not null); pm query-activities resolves ExternalFileInstallActivity as isDefault=true for exactly that URI shape.

Already fixed by earlier commits on this branch (confirmed against current code, marked resolved): long-press tooltips on the three dialogs, and CancellationException rethrow in findExistingCollision.

Verification: full relevant unit test suite green (ExternalFileInstallViewModelTest, TemplateCollectionRepositoryImplTest, FileProviderUtilsTest), plus a fresh on-device regression pass on the .cgt install/overwrite/rename flows on the physical Note20 Ultra (no stray .tmp/temp files left behind in any path).

- Rethrow CancellationException in inspectCollection and installCollection
  (both used runCatching, which was swallowing it into a Result.failure).
- Fix a retry-ability regression the previous commit's staging fix
  introduced: installCollection now copies (rather than moves) the
  candidate into staging and only deletes it after the whole install
  succeeds, so a failed install leaves the source file intact for the
  caller to retry with the same file.
- Add KDoc to TemplateCollectionRepositoryImpl and FileProviderUtilsTest.
- Broaden test coverage: uppercase-collision install/overwrite, the
  remaining invalid targetBaseName cases (backslash, ".", blank), byte-
  content assertions on install/overwrite, and a retry-ability test.

- PluginRepositoryImpl: case-insensitive .cgp extension check, fixing
  permanent data loss for uppercase-named plugin files.
- PluginManagerViewModel: await the first loadPlugins() completion before
  checking for a same-ID conflict, closing a race that could skip the
  signature check on a cold-started install; only ever delete a forwarded
  LocalFile temp copy on decline/failure, never a user-picked ContentUri
  (matches the "delete after install" checkbox's success-only meaning);
  corrected a comment that overstated the deletion invariant.
- PluginManagerActivity: route back-press/tap-outside through
  CancelPendingInstall on both install dialogs, so a forwarded temp file
  is never leaked by a silently-cancelable dialog.
- TemplateCollectionRepositoryImpl: replace the existing collection via a
  backup-swap-restore instead of delete-then-write, so a failed final
  copy can no longer destroy it; give staging/backup files unique names
  so concurrent installs of the same collection don't race on the same
  path.
- TemplateProviderImpl: case-insensitive .cgt scan, matching the
  repository's case-insensitive install/collision handling.
- AndroidManifest: add keyboard/keyboardHidden/navigation to both
  install-flow activities' configChanges, closing the same
  dialog-dropped-on-recreation class of bug for another config axis.
- ExternalFileInstallScreen: disable dismiss/cancel on all three dialogs
  while an install is in flight, so a fast tap can't race a delete
  against the in-progress install; new Flashbar await-shown helpers
  replace a fixed delay with the real animation-complete signal before
  finishing the activity.
- ExternalFileInstallViewModel: widen the setup-wait budget from ~2.7s to
  ~8s to better match a real cold-start's unbounded init chain.

Deferred: TemplateProviderImpl's per-archive parse errors are still only
logged, not surfaced to installCollection's caller - closing that
requires exposing per-archive load state across the templates-api/impl
module boundary, which is disproportionate for this PR relative to how
speculative the failure mode is.

Ran a max-effort /code-review pass over the whole PR and fixed everything it found (commit 6fbf4c1):

Data-loss / security fixes:

  • PluginRepositoryImpl: case-sensitive .cgp check could permanently delete an uppercase-named plugin file - now case-insensitive.
  • PluginManagerViewModel: the same-ID signature check could be skipped if Install was tapped before the async plugin list finished its first load - now awaits that load first.
  • PluginManagerViewModel: declining an overwrite, or a failed install, no longer deletes a user-picked file (only our own disposable forwarded-temp copies are ever cleaned up before a success) - matches the "delete after install" checkbox's actual meaning.
  • TemplateCollectionRepositoryImpl: replaced delete-then-write with a backup-swap-restore, so a failed final copy can no longer destroy the existing collection; staging/backup filenames are now unique per call so concurrent installs of the same collection can't race on the same path.

Other correctness fixes:

  • PluginManagerActivity: both install dialogs route back-press/tap-outside through the same cancel path as their buttons, so a "silently cancelable" dialog can no longer leak a forwarded temp file.
  • AndroidManifest.xml: added keyboard|keyboardHidden|navigation to both install-flow activities' configChanges - closes the same class of bug (a config change silently dropping the forwarded-install dialog) for another axis.
  • ExternalFileInstallScreen.kt: all three dialogs now disable dismiss/cancel while an install is in flight, so a fast tap can't race a file delete against the in-progress install.
  • TemplateProviderImpl: template directory scan is now case-insensitive, matching the repository's already-case-insensitive install/collision logic (an uppercase .CGT collection could previously install successfully but never actually appear in the template list).
  • Replaced a blind 300ms delay before finishing ExternalFileInstallActivity with a real Flashbar "entrance animation finished" signal (new flashSuccessAwaitShown/flashErrorAwaitShown in common), and widened the IDE-setup-wait budget from ~2.7s to ~8s to better match a real cold start.

Deferred, with reasoning: TemplateProviderImpl's per-archive parse failures are still only logged, not surfaced back to installCollection's caller. Properly closing that needs exposing per-archive load state across the templates-api/templates-impl module boundary - a larger change than proportionate for how speculative that specific failure mode is. Flagging rather than silently skipping.

Verification: full relevant unit test suite green, spotlessApply clean, a self-run architecture-review pass (0 violations against ARCHITECTURE.md/ADRs), and a fresh on-device regression pass on the .cgt install/overwrite flow on the physical Note20 Ultra (no crashes, no stray temp/backup files).

- TemplateCollectionRepositoryImpl: escalate (rather than discard) a
  failed backup restore after a swap failure, and no longer report a
  spurious install failure when only the post-swap provider reload
  throws - the file swap is the operation's real postcondition.
- ExternalFileInstallViewModel: cap suggestUniqueBaseName's search so a
  pathological repository can't hang the Rename dialog forever.
- New InstallTempFiles util: shared filesDir/temp staging (extracted
  from near-identical code in ExternalFileInstallViewModel and
  PluginManagerViewModel's ContentUri branch) that also sweeps
  hour-old orphans - covers a temp file left behind if a forwarded
  .cgp's hand-off to PluginManagerActivity never completes.
- FlashbarActivityUtils: extracted a shared configureFlashbar() helper
  so showFlashBar() and showFlashBarAwaitShown() can't silently diverge
  in their builder setup.
- AndroidManifest.xml: documented two known, accepted limitations
  rather than fixing them - pathPattern can't match a mixed-case
  extension without an disproportionate enumeration of every case
  permutation, and suppressing recreation on uiMode/locale/etc. for
  dialog continuity means already-inflated View content can look stale
  until back-and-return (narrower on the Compose screen, which
  recomposes reactively on those axes).

Ran a follow-up /code-review high pass and fixed what it found (commit 0d899a7):

  • TemplateCollectionRepositoryImpl: a failed backup restore (after an already-failed swap) was silently discarding its return value - now logged loudly instead of leaving the user's original collection invisible under a .bak filename. Also stopped a ITemplateProvider reload failure from reporting the whole install as failed when the actual file swap had already succeeded (that was leaving destFile installed on disk while the caller believed nothing happened and would hit a spurious "already exists" on retry).
  • ExternalFileInstallViewModel.suggestUniqueBaseName: capped its search loop so a pathological repository can't hang the Rename dialog forever.
  • New InstallTempFiles util: extracted the near-identical filesDir/temp staging code duplicated between ExternalFileInstallViewModel and PluginManagerViewModel's ContentUri branch, and added an hour-old-orphan sweep - covers a temp file being left behind forever if a forwarded .cgp's hand-off to PluginManagerActivity never completes (e.g. process death mid-handoff).
  • FlashbarActivityUtils: extracted a shared configureFlashbar() so showFlashBar()/showFlashBarAwaitShown() (added earlier this PR) can't silently diverge in their builder setup - confirmed duplication from the previous round.

Documented rather than fixed (with reasoning in the manifest comments): a mixed-case .cgp/.cgt extension (e.g. Plugin.Cgp) won't match android:pathPattern's lowercase/UPPERCASE-only variants - full case-permutation enumeration would bloat the manifest disproportionately for how rare a genuinely mixed-case sender is; and suppressing Activity recreation for dialog continuity (uiMode/locale/etc.) means already-inflated View content can look stale until back-and-return - a pre-existing, already-accepted tradeoff this PR only extended to more config axes, not introduced.

Verified: relevant unit tests green (plus a new test for the suggestion-cap), spotlessApply clean.

- CodeEditorView, FileTreeActionHandler: this PR's own new "cgt" archive
  type was missing from two pre-existing extension allowlists. Opening a
  .cgt from the file tree would edit its raw zip bytes as text (silent
  corruption on save) and get blocked by the 10MB file-size guard that
  every other archive type is exempt from.
- ExternalFileInstallActivity: singleTask + onNewIntent, so a rapid
  double-tap on the same external file collapses into one
  Activity/ViewModel instance (whose receivedUriGate already dedupes by
  Uri) instead of spinning up a second instance that mints an
  independent temp file PluginManagerViewModel's path-based dedup can't
  recognize as the same source. Verified on-device: a duplicate launch
  now hits the same instance and shows one dialog, not two.
- PluginManagerActivity: check the forwarded temp file still exists
  before showing the install-confirmation dialog, so a file removed by
  InstallTempFiles' stale-file sweep surfaces a clear message instead of
  a generic install failure. Also merged the forced/normal dialog
  branches into one builder so a future button/copy change can't be
  applied to only one and reintroduce a leaked-temp-file bug.
- PluginManagerViewModel: clean up a forwarded LocalFile temp copy on
  cancellation too (previously only success/failure paths did), and
  stopped deleteSourceDocument() from swallowing CancellationException.

Another /code-review high pass, fixed what it found (commit 65c7003):

The headline bug: this PR introduces .cgt as a new installable archive type, but two pre-existing archive-extension allowlists elsewhere in the app were never updated to include it:

  • CodeEditorView's ARCHIVE_EXTENSIONS - opening a .cgt from the file tree would have edited its raw zip bytes as text, silently corrupting the archive on save.
  • FileTreeActionHandler's archive exemption - a .cgt over 10MB would get blocked by the "File is too big!" guard that every other archive type is exempt from.

Both fixed by adding TEMPLATE_ARCHIVE_EXTENSION alongside the existing PLUGIN_ARCHIVE_EXTENSION entries.

Other fixes:

  • ExternalFileInstallActivity: added singleTask + onNewIntent, closing a race where rapidly double-tapping the same external file could spin up two Activity/ViewModel instances - each minting an independent temp file that PluginManagerViewModel's path-based dedup guard couldn't recognize as the same source, risking two stacked install dialogs / concurrent installs. Verified on-device: a duplicate launch now hits the existing instance ("intent has been delivered to currently running top-most instance") and shows a single dialog.
  • PluginManagerActivity: checks the forwarded temp file still exists before showing its install-confirmation dialog (it could have been removed by InstallTempFiles' stale-file sweep from a couple commits ago); also merged the forced/normal install-dialog code paths into one builder so a future change can't be applied to only one branch.
  • PluginManagerViewModel: a cancelled install now cleans up its forwarded temp file too (previously only success/failure did), and deleteSourceDocument() no longer swallows CancellationException.

Not fixed, judged out of proportion: ITemplateProvider.reload() re-parsing every installed collection on each install (pre-existing architecture, not a regression), suggestUniqueBaseName's per-iteration directory scan (already bounded to 50 by the previous round's cap, and templates directories are realistically small), and a suggested cross-file "ArchiveType" abstraction spanning 6 files (the two concrete bugs it would have prevented are now fixed directly; the broader refactor is a separate, larger change).

Verified: unit tests green, spotlessApply clean, and an on-device regression pass specifically targeting the singleTask fix (confirmed via dumpsys activity + a clean single-dialog screenshot) plus a .cgt install/cleanup re-check.

- ExternalFileInstallViewModel: fix a regression the singleTask change
  introduced - a rapid second VIEW intent for a *different* file could
  have its confirm-dialog effect overwritten by a slower first request
  that happened to finish its async work later, since the two
  onReceived() calls run as independent coroutines with no ordering
  guarantee. Added a generation counter, assigned synchronously so it
  always reflects real intent-arrival order; a request whose generation
  is no longer current abandons itself (and its temp file) instead of
  emitting a stale effect. Verified on-device: the previous ("clean up
  at start") approach left both files' temp copies on disk; this one
  leaves exactly one, matching whichever file's dialog is showing.
- PluginManagerViewModel: fixed an ownedTempFile assignment race (a
  cancellation landing exactly as the ContentUri copy finished could
  skip the `.also{}` that recorded it, leaking the copy past
  `finally`'s cleanup) by assigning it as a plain statement before the
  copy runs, not after the whole block returns.
- PluginManagerViewModel/PluginManagerActivity/PluginManagerUiState:
  extracted a deleteIfLocalFile() helper, replacing 6 copies of the
  same `if (source is PluginInstallSource.LocalFile) deleteInstallSource(source)`
  guard, and removed CancelPendingInstall's now-dead
  deleteSourceAfterInstall field (the handler stopped reading it once
  an earlier fix switched to checking the source type directly).

One more /code-review high pass turned up a genuine regression from my own previous fix - fixed now (commit 007ce66):

The regression: the singleTask fix from the last round (collapsing a duplicate VIEW intent into one Activity instance) traded one bug for a related one. My first attempt cleaned up the previous pending file at the start of a new onReceived() call - but two onReceived() calls run as independent coroutines with no guarantee the first one finishes (and registers its pending file) before the second one starts its own cleanup check. Verified on-device: sending two different .cgt files in quick succession left both temp files on disk instead of cleaning up the superseded one.

The fix: a generation counter, assigned synchronously (not inside the launched coroutine) so it always reflects real intent-arrival order. Each request checks, right before committing to show its dialog, whether it's still the current generation - if a newer request has since arrived, it abandons itself (and cleans up its own temp file) instead of emitting a stale effect. Re-verified on-device: now exactly one temp file remains, matching whichever file's dialog is actually showing.

Also fixed:

  • A narrower version of the same class of bug in PluginManagerViewModel: a cancellation landing exactly as a ContentUri copy finished could skip the .also{} that recorded the temp file, leaking it past the finally block's cleanup. Fixed by assigning the file reference as a plain statement before the copy runs.
  • Extracted a deleteIfLocalFile() helper replacing 6 copies of the same guard, and removed CancelPendingInstall's now-dead deleteSourceAfterInstall field.

Verified: unit tests green (including a new test locking in the supersession-cleanup behavior), spotlessApply clean, and the exact race re-tested on-device with the fix in place.

- TemplateCollectionRepositoryImpl: the backup step (moving an existing
  destFile aside before the swap) had no copy+delete fallback, unlike
  the swap and restore steps a few lines below - meaning an overwrite
  install could always fail on a device where renameTo() is unreliable
  even for a same-directory move (the exact issue this PR already fixed
  for the swap/restore steps). Applied the same fallback here too.
- ExternalFileInstallViewModel: extend the generation-gating from the
  previous fix to installation completion, not just dialog dispatch -
  confirmTemplateInstall() now captures its generation and checks it
  before sending Finish (so a slow install for an abandoned dialog
  can't tear down the Activity out from under a newer, unrelated
  dialog) and before touching `_isInstalling` (so a stale install
  completing can't re-lock a newer dialog's buttons). dispatchTemplateInstall()
  now also resets `_isInstalling` when committing to show a new dialog,
  so it isn't left stuck "true" by an abandoned generation's
  still-running install.
- InstallTempFiles: throttle sweepStale() to once per 10 minutes
  instead of a full directory scan on every single temp-file creation
  - stale entries can only appear once per hour (MAX_AGE_MS) regardless.

Verification note: the physical test device was unreachable this
round (disconnected mid-session) - verified via the full relevant unit
test suite (including a new test locking in the isInstalling-scoping
fix) and careful tracing of the generation-check logic, which builds
directly on the already on-device-verified mechanism from the previous
commit.

Another /code-review high pass, fixed what it found (commit 08202f8):

A genuine, higher-severity bug this time: TemplateCollectionRepositoryImpl's backup step (moving an existing destFile aside before the swap) had no copyTo fallback - unlike the swap and restore steps a few lines below it, which already have one specifically because renameTo() is known unreliable on-device even for a same-directory move (confirmed earlier in this PR). That meant every overwrite install could fail on exactly the device class this PR already fixed the same issue for elsewhere. Applied the identical fallback to the backup step.

Follow-on from the last fix: the generation-gating I added for the dialog-supersession race didn't cover the installation-completion path - a slow install for an abandoned dialog could still tear down the whole Activity (Finish) out from under a newer, unrelated dialog, and could re-lock that newer dialog's buttons via a shared _isInstalling flag. Extended the same generation check to confirmTemplateInstall()'s completion and to resetting _isInstalling whenever a new dialog is shown.

Also fixed: InstallTempFiles.sweepStale() was doing a full directory scan on every single temp-file creation despite only being able to find anything stale once an hour - throttled to once per 10 minutes.

Note on verification: the physical test device disconnected mid-session, so I couldn't re-verify this round on-device the way I did the last two. Verified instead via the full relevant unit test suite (including a new test locking in the isInstalling scoping fix) and careful tracing - the fix is a direct, narrow extension of the generation-check mechanism from the previous commit, which was verified on-device.

Follow-up: the physical device reconnected, so I re-verified commit 08202f8 on-device after all — fresh install, overwrite (the fixed backup-fallback path), and the dialog-supersession race (two different files in quick succession) all still work correctly, no stray temp/backup files left behind, no crashes in logcat.

davidschachterADFA and others added 3 commits August 17, 2026 10:25
- PluginManagerActivity: a .cgp forwarded from ExternalFileInstallActivity
  could stack a second Plugin Manager instance on top of one the user
  already had open/backgrounded. ForwardToPluginManager's launch Intent
  now carries FLAG_ACTIVITY_CLEAR_TOP|FLAG_ACTIVITY_SINGLE_TOP, and
  PluginManagerActivity gained an onNewIntent() override (mirroring
  ExternalFileInstallActivity's own singleTask handling) so a reused
  instance still processes the forwarded install instead of silently
  dropping it.
- PluginManagerActivity: the forwarded-install file.exists() check ran
  synchronously on the main thread during onCreate()/onNewIntent(); moved
  onto Dispatchers.IO like the other file-system checks in this flow.
- PluginManagerActivity: dropped showInstallConfirmation's redundant
  forceDeleteSource parameter - it was 100% determined by source's
  runtime type at both call sites, so compute it internally instead.
- ExternalFileInstallViewModel: confirmTemplateInstall's success message
  now includes the target base name, so the toast is unambiguous even
  when a slow install completes after a newer, unrelated dialog has
  already taken over the screen (it must still fire per the existing
  isInstalling-scoping test - the install genuinely succeeded).
- ExternalFileInstallViewModel: collapsed the two structurally-identical
  plugin/template availability-check blocks into one.
- InstallTempFiles: lastSweepAtMs is read/written from coroutines
  PluginManagerViewModel and ExternalFileInstallViewModel can launch on
  different dispatchers - switched to AtomicLong with compareAndSet so
  two near-simultaneous callers can't both pass the throttle check.

Not fixed (out of scope / pre-existing, not regressions from this PR):
- InstallFileAction not recognizing .cgt for the in-editor "Install"
  action - a new feature (wiring TemplateCollectionRepository into that
  action), not a bug in the external-open flow this ticket covers.
- ITemplateProvider.getInstance(reload=true) rescanning all installed
  collections on every install - existing reload API behavior, not
  something introduced here.
- FeedbackManager/FeedbackEmailHandler's duplicated PixelCopy capture
  logic - pre-existing, unrelated duplication only touched by this PR's
  formatting pass.

Verification: full app unit test suite green; on-device (R5CN80KZCKD)
reproduction of the duplicate-instance scenario (two .cgp VIEW intents
in quick succession while the first's confirm dialog is still open)
confirms a single PluginManagerActivity instance (same ActivityRecord/
task) handles both, no crash.

- Around line 136-164: The replacement flow around installCollection() must
serialize concurrent installations targeting the same canonical destination
path. Hold a per-destination lock across collision detection, staging, backup,
swap, cleanup, and provider reload, so only one call can replace a given
destFile at a time while allowing different destinations to proceed
concurrently.

- Around line 32-33: Update newTempFile and its caller
ExternalFileInstallViewModel.onReceived so temp-directory creation and
sweepStaleIfDue filesystem work run on Dispatchers.IO, either by making
newTempFile suspend or invoking the sweep within the existing IO block; preserve
the current stale-file cleanup behavior.

- ExternalFileInstallViewModel: confirmTemplateInstall() captured the
  live currentRequestGeneration counter instead of the generation the
  on-screen dialog actually belongs to. A second VIEW intent bumps that
  counter synchronously before its own dialog is shown, so tapping
  Install/Overwrite/Rename on the still-visible (but now stale) prior
  dialog in that window got misattributed to the newer generation - on
  success this incorrectly sent Finish, tearing the Activity down (and
  its viewModelScope) out from under the newer, still in-flight request.
  Fixed by tracking pendingConfirmationGeneration alongside
  pendingConfirmationTempFile and keying confirmTemplateInstall() off
  that; also guards against acting on a tempFile that's already been
  superseded (and deleted) entirely.
- ExternalFileInstallViewModel: IgnoreTemplateInstall had the same root
  cause - a stale Cancel tap unconditionally sent Finish regardless of
  whether pendingConfirmationTempFile still matched. Now a no-op when
  it doesn't.
- ExternalFileInstallViewModel: suggestUniqueBaseName()'s attempt-bound
  check ran before the collision check, so the final candidate returned
  when MAX_SUGGESTION_ATTEMPTS is hit was never actually checked for
  collision. Reordered the && operands so the bound only short-circuits
  after that last check has run.
- ExternalFileInstallViewModel: template install failures showed a
  generic, non-actionable message; now includes the underlying reason
  (reserved name / already exists / swap failure) via a %1$s arg,
  matching PluginManagerViewModel's equivalent error path.
- PluginManagerViewModel: _uiEffect used the default rendezvous channel,
  the same latent drop-before-collector-attaches bug class this PR
  already fixed for ExternalFileInstallViewModel's channel. Switched to
  Channel.BUFFERED for consistency; not user-visible today, but the
  channel now also serves the forwarded-.cgp path.
- TemplateCollectionRepositoryImpl: extracted the renameTo()+copyTo()
  fallback (triplicated across the backup/swap/restore steps) into a
  single moveFile() helper.

Not fixed (narrow races / low-value at this stage, not regressions):
- installCollection() has no per-destination-name locking, so two
  concurrent installs to the same target name could race on the final
  swap. Requires two attachments sharing a name AND overlapping
  generations to hit; accepted as last-write-wins for now.
- InstallTempFiles' hour-old sweep could delete a pending confirmation's
  temp file if the user leaves a dialog open that long; would need
  cross-ViewModel "file in use" tracking to fix properly.
- installPlugin() awaits initialLoadCompleted before copying the
  incoming URI, when the two could run concurrently - a cold-start-only
  latency nicety, not a correctness issue.
- dispatchTemplateInstall() does its zip-read/collision-check I/O before
  its own generation check - inherent to check-then-act, the I/O can't
  be skipped without knowing in advance it'll be superseded.

Verification: full app unit test suite green, including two new
regression tests for the generation-capture fix (confirming a stale
dialog surfaces success without Finish-ing over a newer request;
ignoring a stale dialog doesn't Finish over a newer one) and a
strengthened suggestUniqueBaseName test asserting the give-up candidate
was actually checked. On-device (R5CN80KZCKD): fresh install and
overwrite (via the new moveFile()) both verified with a real .cgt
archive - correct dialog content, clean success, no crash, no stray
.tmp/.bak files left in the templates directory.

- TemplateCollectionRepositoryImpl: installCollection() had no
  per-destination-name locking, so two concurrent installs targeting
  the same case-insensitive base name could both pass the collision
  check before either wrote destFile, and the later swap would silently
  clobber the earlier one. Wrapped the whole operation in a Mutex keyed
  by the lowercased target base name (independently flagged by both
  CodeRabbit and the prior code-review round, which this addresses).
- InstallTempFiles: newTempFile() ran mkdirs() and its periodic
  directory sweep/delete on whatever dispatcher the caller happened to
  be on - ExternalFileInstallViewModel.onReceived() called it without
  a surrounding withContext(Dispatchers.IO), so that filesystem work
  ran on the main thread. Made newTempFile() suspend and dispatch to
  Dispatchers.IO internally, so no caller can repeat the mistake.

Not changed (already-deliberated design decisions / false positive):
- CodeRabbit suggested a superseded install's completion should suppress
  its ShowSuccess effect entirely, since it can render over a newer
  request's dialog. This was already addressed in the prior commit by
  including the collection's name in the message so the toast is
  unambiguous regardless of what's currently on screen - suppressing it
  outright would mean a genuinely successful install never gets
  reported to the user. Replied on the thread with this reasoning.
- CodeRabbit's JUnit Jupiter migration suggestion doesn't correspond to
  any actual change in this PR - both flagged test files still use
  @RunWith(RobolectricTestRunner::class) and plain JUnit4 @Test/runTest,
  unchanged. Replied noting this appears to be a false positive.

Verification: full app unit test suite green. On-device (R5CN80KZCKD):
fresh install of a real .cgt archive after these changes - correct
dialog, clean success, no crash, no stray .tmp/.bak files in the
templates directory.

…h review round

- ExternalFileInstallViewModel: confirmTemplateInstall() clears
  pendingConfirmationTempFile on entry (transferring tempFile's
  "ownership" to the install attempt, per the sixth-round generation
  fix), but never restored it on install failure. The dialog is
  deliberately left open so the user can retry - but with
  pendingConfirmationTempFile left null, every subsequent tap
  (Install/Overwrite/Rename again, or Cancel/back) silently no-ops
  forever, since both confirmTemplateInstall() and IgnoreTemplateInstall
  key off it matching. The excludeFromRecents=true trampoline Activity
  has no other way out at that point short of force-stopping the app.
  Fixed by restoring pendingConfirmationTempFile/Generation in the
  onFailure branch (gated on isCurrentGeneration, same as everything
  else there) so a retry or cancel on the still-open dialog matches
  again.
- ApkInstaller: isValidApk's extension check was case-sensitive
  (`== "apk"`), inconsistent with every other extension check this PR
  touched. An uppercase .APK (common from browsers/email/file managers
  that preserve sender casing) silently failed with no error shown.

Not changed (pre-existing gaps, not regressions from this PR, larger
lifts than warranted at this point):
- InstallFileAction's file-tab "Install" for .cgp calls
  PluginRepository.installPluginFromFile() directly, bypassing the
  signature-mismatch/overwrite-confirmation check every other plugin
  install entry point goes through - pre-existing behavior, would need
  routing this action through the same ViewModel-level conflict
  resolution.
- PluginRepositoryImpl.installPluginFromFile has no backup/rollback or
  per-target locking, unlike TemplateCollectionRepositoryImpl - a
  structurally similar but substantially larger lift given plugin
  install's uninstall/restart semantics.
- Two distinct .cgp files forwarded to an already-open PluginManagerActivity
  in quick succession can each pass markPendingInstallHandled's
  per-value dedup and stack two native AlertDialogs - would need the
  same generation-tracking machinery ExternalFileInstallViewModel has,
  ported to the plugin flow's more complex dialog chain.

Verification: full app unit test suite green, including two new
regression tests (retrying Install after a failed install actually
re-attempts it; cancelling after a failed install still finishes) that
fail against the pre-fix code and pass against the fix.

On-device verification of d6eb6d0's stuck-dialog fix (R5CN80KZCKD, physical device):

  1. Opened core.cgt -> name-collision dialog ("core" already installed) -> tapped Overwrite -> failed with "reserved name" error, dialog stayed open as designed.
  2. Tapped Overwrite again (retry) -> logcat confirms a fresh installCollection() call fired and failed the same way - pre-fix, this second tap would have silently no-op'd (pendingConfirmationTempFile stayed null after the first failure).
  3. Tapped Cancel on the still-open dialog -> Activity finished cleanly - pre-fix, this would have also silently no-op'd.

No crashes. Confirms the fix works as intended.

AlertDialog's default confirmButton/dismissButton row can't fit three
actions (Overwrite / Rename & Install / Cancel) on one line, so it wrapped
awkwardly - one button alone on the first row, the other two crammed
together on a second row. Moved all three into the confirmButton slot as
a right-aligned Column instead, so they stack one per row.

…/ Uris

QA (Daniel Alome, ticket comment) found that opening a real .cgp
attachment from the Files app failed silently: Storage Access Framework
providers (Android's Downloads app, most file managers) hand out opaque
document IDs like content://.../document/msf%3A19, with no filename
anywhere in the Uri. Every existing intent-filter here requires a
pathPattern match, so none of them can ever match this - the OS instead
fell through to an unrelated app that happened to declare an
unconstrained VIEW+content+application/octet-stream filter (Google
Pay's pkpass handler), which claimed the single unambiguous match and
opened/closed with no chooser and no visible error.

This exact tradeoff was already called out as a "known limitation, not
fixable via manifest matching" in this file's own comment, on the
reasoning that the only pathPattern-less alternative was mimeType="*/*"
- which would register this app as a candidate for every file view
intent on the device. That reasoning missed a middle ground: a
pathPattern-less filter matching only the small, specific set of
mimeTypes a binary/zip attachment actually carries
(application/octet-stream, application/zip, application/x-zip-compressed)
is narrow enough to be worth it. Added as a fourth intent-filter block
and updated the manifest's own "known limitations" comment accordingly.

This does mean the app now offers itself as an "Open with" candidate
for any octet-stream/zip content from any app, not just .cgp/.cgt -
accepted since the real extension is still re-validated from
DISPLAY_NAME once opened (ExternalFileInstallViewModel.onReceived), so
a mismatched file is rejected gracefully rather than mishandled.

Verification: `./gradlew :app:processV8DebugMainManifest` succeeds. On
a physical device (R5CN80KZCKD), simulated a real Downloads-provider-
style opaque content Uri (content://com.android.providers.downloads.
documents/document/msf%3A999, type application/octet-stream) via `am
start` - confirmed via logcat/dumpsys and a screenshot that "Code on
the Go" now appears in the "Open with" chooser, where before this fix
it was completely absent from the candidate list (reproducing exactly
the bug QA reported). No crash when actually opened.
