Ports @solana-mobile/webshell-cli into this CLI as webshell init and webshell build, per docs/plans/2026-09-02-webshell-port.md. Rewritten to house conventions (clack prompts, DI-injectable runners, bun:test — 52 new tests); the Android template is vendored at templates/webshell-android/ and shipped in the npm tarball; a new Webshell workflow builds a real APK nightly and on webshell changes. Template toolchain and library versions are aligned with the kotlin-compose-minimal template from solana-mobile/templates#9 (AGP 9.3.2, Kotlin 2.4.10, Gradle 9.7.1, Compose BOM 2026.08.00, compile/targetSdk 37), and its Gradle config keys use the SOLANA_MOBILE_* vocabulary. Verified end-to-end locally: fully-flagged init runs prompt-free and build produces a signed app-release.apk on this toolchain.

Deliberately dropped from the reference: the JDK/Android-SDK auto-installer and ~/.webshell state dir, the webshell doctor subcommand, the arbitrary Node ≥ 24 gate (nothing needed it — verified empirically), and the WEB_SHELL_* env vars (now SOLANA_MOBILE_KEYSTORE_PASSWORD / SOLANA_MOBILE_KEY_PASSWORD, no fallback).

Future doctor checks (suggestions only, doctor untouched here): JDK 17+ present, ANDROID_HOME/SDK dir resolvable, platforms;android-37, build-tools;37.0.0.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 0a5f9

The PR adds WebView-shell generation and APK builds, but the current implementation has merge-blocking reliability and security issues: its automation invokes unsupported flags, some valid inputs can produce broken or partially generated projects, and generated apps can mishandle URLs, popup schemes, host matching, and backed-up browser state. These should be fixed before merging.

Keep the path filter aligned with all Webshell dependencies.

This job also depends on src/app.ts, src/core/data-access/command-types.ts, src/core/data-access/run-executable.ts, package.json, and ./.github/actions/setup. Changes in those paths can break webshell build or packaging without triggering this APK check. Add the relevant paths to pull_request.paths.

Add a packed-artifact smoke test.

findWebshellTemplateDir resolves templates/webshell-android from the published package, but the workflow runs checkout dist/cli.mjs and existing tests mock this lookup. Pack and install the artifact in a temporary directory, then run webshell init.

Remove the duplicated foreground cleanup.

Lines 234-239 delete sibling-extension assets by name. clearPreviousForegroundAssets (lines 242-251) performs the same cleanup through readdir and covers extensions outside SUPPORTED_ICON_EXTENSIONS. Keep only the clearPreviousForegroundAssets call.

Verify the template directory before you return it.

The walk stops at the first ancestor that contains package.json and returns the templates path without checking it. If a nested package.json appears above this module in a published or bundled layout, the function returns a path that does not exist. The error then surfaces later as an ENOENT from readdir in copyWebshellTemplate, not as the clear message on Line 14.

♻️ Continue the walk when the template directory is missing
-    if (existsSync(join(current, 'package.json'))) {
-      return join(current, 'templates', 'webshell-android')

Share one package-segment normalizer.

normalizeSuggestionSegment repeats the logic of normalizeApplicationIdSegment in src/webshell/data-access/rename-android-package.ts (lines 396-431). The two copies already differ, because only the second one handles reserved segments. If one copy changes, the suggested application ID and the derived Kotlin package can drift apart. Export one helper and let each caller add its own extra rules.

In @.github/workflows/webshell.yml:
- Line 34: Update the actions/checkout step to set persist-credentials to false,
preventing the GITHUB_TOKEN from being stored in local Git configuration while
preserving the existing checkout behavior.

In `@src/webshell/data-access/apply-branding.ts`:
- Around line 259-269: Update the color normalization logic to convert CSS
alpha-last hex values to Android alpha-first ordering before writing colors:
reorder 8-digit `#RRGGBBAA` values to `#AARRGGBB`, and expand 4-digit `#RGBA` values
as `#AARRGGBB`. Keep 3-, 6-digit handling and uppercase output unchanged, using
the existing normalization function as the change point.

In `@src/webshell/data-access/keystore.ts`:
- Around line 87-90: Update ensureKeystore, runCommand, and runExecutable so
keystore and key passwords are delivered through a target-JDK-supported secret
mechanism rather than keytool/spawn arguments; preserve prompt resolution while
removing both passwords from argv and do not use stdin piping.

In `@src/webshell/webshell-feature-build.ts`:
- Line 70: Update runWebshellBuild so Windows invokes gradlew.bat through
cmd.exe with safely quoted arguments, while preserving the existing direct Unix
gradlew invocation on non-Windows platforms. Add a Windows-specific build test
covering the command and argument handling.

In `@src/webshell/webshell-feature-init.ts`:
- Line 70: Update the default fetch implementation assigned to fetchFn so remote
manifest and icon requests have a finite timeout, causing stalled requests to
abort instead of hanging webshell init. Preserve the existing URL handling and
custom fetchFn behavior.

In
`@templates/webshell-android/app/src/main/java/com/solanamobile/webshell/MainActivity.kt`:
- Line 94: Update the WebSettings configuration in MainActivity so mixed content
defaults to WebSettings.MIXED_CONTENT_NEVER_ALLOW instead of permitting all
mixed content. Preserve mixed-content support only as an explicit opt-in through
a separate deliberate configuration path.

In
`@templates/webshell-android/app/src/main/java/com/solanamobile/webshell/WebShellChromeClient.kt`:
- Line 37: Update WebShellChromeClient.onConsoleMessage to return immediately
when isDebug is false, before any console message reaches Log.println. Preserve
the existing debug-only logging behavior and formatting for enabled debug
builds.
- Line 51: Update onCreateWindow to destroy the temporary newWebView after
launching the external navigation intent, and override onCloseWindow to destroy
the corresponding popup WebView when it closes. Ensure cleanup occurs for both
navigation and close paths without changing existing popup behavior.

In
`@templates/webshell-android/app/src/main/java/com/solanamobile/webshell/WebShellViewClient.kt`:
- Around line 25-58: Update every external activity launch in the
WebShellViewClient navigation handling to use the existing launchExternal
helper, including the solana-wallet branch, the external http/https branch, and
the fallback else branch. Ensure launchExternal catches missing handlers without
crashing and adds FLAG_ACTIVITY_NEW_TASK when required for non-activity
contexts.
- Around line 61-75: Update handleIntentScheme to sanitize parsed intents before
launching by clearing component and selector, adding CATEGORY_BROWSABLE, and
removing URI-grant flags; validate browser_fallback_url so only http and https
schemes are launched. Replace or support the current resolveActivity check for
API 30+ without manifest queries by launching directly and catching
ActivityNotFoundException, while preserving graceful handling when no handler
exists.

In `@templates/webshell-android/gradlew.bat`:
- Line 1: Convert gradlew.bat to CRLF line endings and add a .gitattributes rule
pinning this batch file to eol=crlf so the endings are preserved in checkouts
and npm tarballs; leave the upstream Gradle idioms unchanged.

In `@test/webshell.test.ts`:
- Around line 1325-1327: Await the rejection assertion in the test using
app.parseAsync for the --version-code validation, ensuring the expected error is
actually checked and the promise is not left floating.

Remove the duplicated stale-asset cleanup.

writeLauncherForeground deletes stale foreground assets by iterating SUPPORTED_ICON_EXTENSIONS. clearPreviousForegroundAssets then deletes stale assets by reading drawable-nodpi. The directory scan already covers every file the loop targets, so this block is redundant work that must be kept in sync with the extension set.

The extension parameter then becomes unused, so drop it from the signature and from the call site at line 61.

marker is a local constant and is never empty, so the if (marker.isEmpty()) branch cannot run. The function also takes only one parameter, so the named-argument call at Line 104 adds no clarity.

193-198: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Resolve the signing passwords before the template is copied.

Every other cancellation path returns before copyTemplate runs. The password prompt is the only one that runs after the project files are written. If the user cancels here, the target directory keeps a partially generated project with no twa-manifest.json, and the next init needs --force.

Consider resolving the passwords right after keystoreAlias, and keep createKeystore where it is.

Ports @solana-mobile/webshell-cli into this CLI as `webshell init` and `webshell build`. Init generates a native Android WebView-wrapper project from a vendored Gradle template (templates/webshell-android, shipped in the npm tarball): applies url/applicationId/version via SOLANA_MOBILE_* gradle.properties keys, renames the Kotlin package, seeds branding from a web manifest.json or Bubblewrap twa-manifest.json, creates the signing keystore when missing, and writes a Bubblewrap-compatible twa-manifest.json. Build runs the project's Gradle wrapper with signing passed as -P properties and passwords only via SOLANA_MOBILE_KEYSTORE_PASSWORD / SOLANA_MOBILE_KEY_PASSWORD env or prompt, surfacing Gradle errors raw. Rewritten to house conventions (clack prompts, DI-injectable runners, bun:test - 52 new tests) with a CI workflow that builds a real APK nightly and on webshell changes. Deliberately dropped from the reference: the JDK/SDK auto-installer and ~/.webshell state dir, the webshell doctor subcommand, the arbitrary Node 24 gate, and the WEB_SHELL_* env vars.
