Summary

Adds first-class Android APK support to the Tauri shell: mobile-safe runtime boundaries, reproducible ARM APK builds, signed release packaging, CI coverage, and live emulator/physical-device validation. The final review pass also preserves in-app routing/login, prevents native-engine handshake hangs, and hardens release signer identity and permissions.

Validation Failures

The full client suite still contains environment-bound Scryfall cases that require a service on localhost:3000; earlier full-suite attempts failed those cases with ECONNREFUSED. Android/review-focused suites, direct protocol/type checks, and all Tauri library tests pass. The composite pnpm run type-check also resolves a machine-global pnpm 11 from its nested script on this Windows host, so its two constituent checks were run directly with pnpm 9.15.9 and both passed.

CI Failures

None.

Walkthrough

This change adds Android Tauri builds and releases, separates mobile and desktop runtime behavior, centralizes native-engine contracts, adds host-platform detection, updates frontend platform gates, and replaces the shell plugin with the opener plugin.

Changes

Android Tauri support

Layer / File(s) Summary
Native engine contracts and mobile compatibility
client/src-tauri/src/native_engine_contract.rs, client/src-tauri/src/mobile_compat.rs, client/src-tauri/src/native_bridge.rs, client/src-tauri/src/native_engine.rs
Native-engine and bridge payloads use shared serialized contracts. Mobile commands return standardized unsupported-platform responses.
Platform-aware Tauri runtime and configuration
client/package.json, client/src-tauri/..., client/src/services/platform.ts, client/src/__tests__/main.bootstrap.test.tsx
Tauri startup, capabilities, configuration, and host-platform detection distinguish desktop, Android, and iOS execution.
Desktop-only frontend services and UI
client/src/services/*, client/src/components/*, client/src/pages/*, client/src/pwa/*, client/src/**/__tests__/*
Update, fullscreen, external-link, server-detection, native-engine, and desktop-only UI paths now require desktop Tauri detection. Tests cover mobile, desktop, and browser behavior.
Android CI and release delivery
.github/workflows/ci.yml, .github/workflows/shell-release.yml, README.md
CI builds and validates an ARM64 debug APK. Release automation builds signed ARM64 and ARMv7 APKs, validates them, and attaches them to releases.

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

Merge Risk: 🟡 Moderate · up to 31f52

This PR adds Android APK build and signing support, but the release instructions name different secrets than the workflow reads, so releases configured from the documentation fail before signing; an existing desktop capability permission concern also remains unresolved. Merge should wait for the secret contract to be corrected and that permission change to be explicitly confirmed.

P1: Release workflow Android build job uses shared caching

Release workflow caches pnpm and Rust toolchain, exposing signed release APKs to cache poisoning.

Remove cache: pnpm and cache-shared-key from the release workflow's Android build job.

Assert the value the mobile path resolves to.

This test proves only a negative: no probe of localhost:9374. Android has no sidecar, so the resolved address is the whole feature. The test never checks what detectServerUrl() returns on mobile, and it does not seed useMultiplayerStore.serverAddress. A regression that returns an empty string or an unreachable default still passes.

Add the positive cases: with no stored address, assert the production default; with a valid stored WebSocket address and a reachable health endpoint, assert the stored address is returned.

Assert the exact key payload, not expect.any(Object).

The Rust command deserializes key as an externally tagged NativeEngineKey, so the wire shape must stay {"release":{"version":"…"}}. client/src-tauri/src/native_engine_contract.rs locks that shape with byte-exact tests. This assertion accepts any object, so a future rename or extra wrapper on the JS side passes here and then fails at runtime with a Tauri deserialization error.

This test cannot prove the browser gate, and it leaks mocks.tauri into later tests.

Two problems.

First, installTauriExternalLinkHandler returns early on handlerInstalled before it evaluates isTauri(). beforeAll already set handlerInstalled to true. Both calls at Line 88 and Line 90 therefore return through the idempotency guard, and expect(add).not.toHaveBeenCalled() passes whether or not the isTauri() gate exists. Delete the isTauri() check from the implementation and this test still passes. Cover the browser case in a separate module registry: call vi.resetModules(), set mocks.tauri = false, re-import ../externalLinks, then assert no listener is added.

Second, Line 89 sets mocks.tauri = false and afterEach never restores it. The tests at Lines 94-110 then run with mocks.tauri === false. They pass today only because the installed closure does not re-read isTauri() per click. Reset mocks.tauri in afterEach, as openExternal.test.ts does.

♻️ Reset the shared mock state

   mocks.bundled = false;

cargo test now fails when node_modules is absent.

installed_android_config_schema_admits_only_the_four_real_properties reads ../node_modules/@tauri-apps/cli/config.schema.json and unwraps the read. Any Rust-only job or a local cargo test before pnpm install panics with a file-not-found error rather than a clear signal.

Add an explicit skip or a descriptive failure when the schema file is missing, so the test states the prerequisite instead of panicking on unwrap.

         let schema_path = Path::new(env!("CARGO_MANIFEST_DIR"))

Pin the version through the base config, not a literal.

verify_android_config compares config.version against the literal "0.60.0", and desktop_config_is_typed_and_preserves_the_base_authority repeats the same literal. Every release bump breaks both tests, and cargo-release bumps this version.

Read the expected product name, version, and identifier from the parsed base tauri.conf.json. The test then still proves that the Android merge inherits the base authority, without a literal that goes stale.

Make the capability test match Tauri’s ACL semantics.

resolve_capabilities only supports trailing-* URL prefixes and exact window labels. Tauri uses URLPattern matching for remote URLs and glob matching for window labels. It also panics when a valid platforms: null value is present. Use the available Tauri capability types where practical; otherwise document the supported subset and add tests for these valid patterns.

Assert Android gating through rendered behavior.

Both Android component tests inspect source text instead of rendering the component. In MenuPage.android.test.tsx, this can miss alternate ungated exit paths; in PreferencesModal.android.test.tsx, harmless JSX refactors can fail the test while an actual native-engine control remains unguarded. Mock isDesktopTauri() and render each component, asserting the controls are absent on Android and present and functional on desktop.

Inline comments:
In @.github/workflows/shell-release.yml:
- Around line 474-479: Update the APK verification flow around APKSIGNER and
signer_digest to load the protected expected SHA-256 certificate digest and
require each extracted digest to match it, in addition to retaining the existing
non-debug and cross-APK consistency checks. Fail the workflow when the expected
digest is missing or either APK signer differs from it.

In `@client/src-tauri/capabilities/default.json`:
- Around line 17-23: Update the local-shell-desktop capability permissions to
include updater:default, process:allow-exit, and process:allow-restart, and
extend the associated local desktop capability test to assert all three
permissions are present.

In `@client/src/services/__tests__/nativeEngineSocket.test.ts`:
- Around line 62-70: Update NativeEngineSocket.connect() so non-desktop terminal
events are deferred until openPhaseSocket() has assigned its onerror and onclose
handlers, allowing the handshake promise to reject instead of remaining pending.
Add a regression test covering handshake rejection and use vi.waitFor for the
asynchronous state transition.

In `@client/src/services/externalLinks.ts`:
- Around line 46-48: Update the click handler around isOpenableExternalUrl so
relative, fragment, and other non-external href values return without calling
event.preventDefault(). Only prevent the default after resolving an absolute
HTTP(S) URL that is handled by the opener plugin, preserving normal internal and
fragment navigation.

In `@README.md`:
- Around line 170-177: Update the release signing documentation to identify
ANDROID_KEYSTORE_BASE64 as the CI secret, noting that CI decodes it into a
runner-local keystore file; distinguish this from the local Gradle
PHASE_ANDROID_KEYSTORE_FILE path variable while preserving the other
signing-input requirements.

---

Nitpick comments:
In `@client/src-tauri/src/lib.rs`:
- Around line 260-292: Update
installed_android_config_schema_admits_only_the_four_real_properties to handle a
missing config.schema.json explicitly: skip the test or fail with a descriptive
prerequisite message instead of unwrapping the file read. Preserve the existing
schema assertions when the file is present.
- Around line 176-183: Update verify_android_config and
desktop_config_is_typed_and_preserves_the_base_authority to derive the expected
product name, version, and identifier from the parsed base tauri.conf.json
rather than hard-coding "0.60.0"; compare the merged configuration against those
base values while preserving the existing inheritance assertions.
- Around line 386-424: Update resolve_capabilities to follow Tauri ACL
semantics: use URLPattern matching for remote URLs and glob matching for window
labels instead of suffix-prefix and exact comparisons, and handle platforms:
null without panicking. Reuse available Tauri capability types where practical;
otherwise document the supported pattern subset and add tests covering valid
URL, window-glob, and null-platform cases.

In `@client/src/pages/__tests__/MenuPage.android.test.tsx`:
- Around line 5-10: Replace the source-text assertions in the MenuPage test with
rendered behavior coverage: mock the platform helpers from
../../services/platform, render MenuPage with isDesktopTauri returning false and
assert the process-exit control is absent, then return true and assert it is
present and dispatches process exit. Follow the mocking and rendering pattern
used by the sibling Android tests.

Apply the same fix in
`@client/src/components/settings/__tests__/PreferencesModal.android.test.tsx`
around lines 5 - 9: The same source-text testing pattern and rendered-behavior
remediation apply to the preferences control.

In `@client/src/services/__tests__/externalLinks.test.ts`:
- Around line 86-92: Update the externalLinks tests so the browser gate is
exercised in a fresh module registry: reset modules, set mocks.tauri to false,
re-import the module, and verify installTauriExternalLinkHandler adds no
listener. Restore mocks.tauri in afterEach so later tests, including the
existing handler tests, retain the default mock state.

In `@client/src/services/__tests__/nativeEngine.test.ts`:
- Line 42: Update the assertion for invokeMock in nativeEngine.test.ts to verify
the exact ensure_native_engine payload, including the externally tagged key
shape release with its version value, instead of accepting any object. Preserve
the existing command name and derive the expected version from the test setup.

In `@client/src/services/__tests__/serverDetection.test.ts`:
- Around line 26-30: Extend the mobile-path test for detectServerUrl with
positive return-value coverage: when useMultiplayerStore.serverAddress is unset,
assert the production default is returned; when it contains a valid stored
WebSocket address and its health endpoint is reachable, assert detectServerUrl
returns that stored address. Keep the existing assertion that localhost:9374 is
never probed.

/review-impl — Add Android APK support (PR #7612)

Reviewed the diff against merge-base(origin/main, HEAD) = 875986b14e, head 9633de818e. Scope reviewed: the Rust shell, the frontend platform boundary, the capability matrix, and both workflows. Generated Android assets (icons, gradle wrapper, gen/schemas/*) were spot-checked, not line-reviewed.

The mobile-safe boundary design is sound: a single host_platform IPC latch resolved once before React mounts, a shared native_engine_contract so the mobile stub emits the identical wire ABI, and a four-way capability split that keeps updater/process/fullscreen off mobile. Two findings block, and I have verified both against sources outside this diff.

Blocking

  1. The pre-host_platform desktop fallback can never fire (client/src/services/platform.ts:16). Tauri rejects the invoke through the ACL gate, not the command-dispatch gate, so the error string is "Command host_platform not allowed by ACL" — never the "Command host_platform not found" this compares against. Every already-installed desktop shell therefore resolves null, and isDesktopTauri() stays permanently false: the updater never registers (self-sealing — the updater is the only channel that could ship a shell with the command), and fullscreen, exit, the native-engine toggle, the native bridge, and sidecar detection all silently disappear. Details inline.

  2. release-shell now depends on build-android, which cannot pass (.github/workflows/shell-release.yml:510). The five Android secrets it requires are not configured on the repository. The next shell release publishes nothing at all — desktop artifacts included. Details inline.

Non-blocking

Seven inline findings on test instrument validity, source-text-grep tests, redundant guards, a triplicated versionCode formula, and an unguarded hand-edited generated Gradle file.

Outside the rubric, for the maintainer

android-debug-apk becomes a required 30-minute job on every PR (ci.yml:695), with a cold sdkmanager NDK+platform download each run and no SDK caching. On a merge-queue repo that is a material latency and flake surface; worth a deliberate decision rather than a side effect of this PR.

One caveat on faithful reporting: I could read repository and environment secrets but not organization-level secrets (403). Finding 2 assumes the Android secrets are not org-level.

Blocking — this fallback is unreachable, and its failure silently disables the desktop shell for every already-installed user.

The premise is that an older shell without the host_platform command rejects the invoke with "Command host_platform not found". That string does exist in Tauri, but it is produced by a branch this call can never reach.

In tauri-2.11.5/src/webview/mod.rs the ACL gate runs before command dispatch:

// mod.rs:1818-1851
if (plugin_command.is_some() || has_app_acl_manifest || !is_local)
  && request.cmd != FETCH_CHANNEL_DATA_COMMAND
  && invoke.acl.is_none()
{
  #[cfg(not(debug_assertions))]
  invoke.resolver.reject(format!("Command {} not allowed by ACL", request.cmd));
  return;   // <-- returns here
}
...
// mod.rs:1913 — only reachable past the gate above
if !handled { resolver.reject(format!("Command {command} not found")); }

On the base commit 875986b14e, all three arms of that gate are armed for an old shell:

  • has_app_acl_manifest is true — client/src-tauri/permissions/ already contains audio-health.toml and legacy-storage.toml.
  • is_local is false — the shell loads https://phase-rs.dev remotely via the remote-shell capability.
  • invoke.acl.is_none() is true — the base capabilities/default.json has no allow-host-platform (this PR introduces it).

So the rejection is "Command host_platform not allowed by ACL" in release builds, or the long resolve_access_message text in debug builds. Neither is === to the expected literal, so hasProvenDesktopUserAgent() is never consulted and initializeHostPlatform() returns null.

Blast radius on the existing desktop fleet, the moment the new web build deploys to phase-rs.dev/preview.phase-rs.dev:

consumer effect
tauriUpdater.ts:191 registerTauriUpdater() no-op — and the updater is the only channel that could deliver a shell containing host_platform, so this is self-sealing
FullscreenButton.tsx:30 mobileTauri becomes true → component returns null, button vanishes
MenuPage.tsx:84 exit button vanishes
PreferencesModal.tsx:441 native-engine toggle vanishes
nativeEngine.ts:49,87 native engine unreachable; NativeEngineSocket throws
serverDetection.ts:69 localhost sidecar probe skipped

The cleanest fix keeps the fail-closed intent while removing the string coupling: treat any probe failure as "unknown" and let the user-agent evidence decide, rather than gating the UA check behind an exact Tauri-internal message. That also stops the check from silently rotting the next time Tauri edits either message.

Non-blocking — the positive fallback path is only proven for one of three desktop platforms.

This suite is otherwise the strongest test in the PR: it covers the shared-promise latch, the malformed-payload matrix, and three fail-closed ambiguity cases. But the fallback it guards is the entire compatibility story for already-installed shells, and only the Windows WebView2 user agent is exercised on the success path.

The two untested branches of hasProvenDesktopUserAgent() are:

  • macOS WKWebView — Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 … with maxTouchPoints === 0. The suite tests the negative of this (touchPoints 5 → null) but never the positive, so a regression in the Macintosh; Intel Mac OS X alternation would pass.
  • Linux WebKitGTK — X11; Linux x86_64. The X11; (?:Linux|Ubuntu) and Linux x86_64 alternations are entirely unexercised.

Two more it.each rows would close it. (This is separate from the platform.ts:16 blocker — even once the error-matching is fixed, these branches decide whether macOS and Linux users keep their updater.)

Blocking — this makes the whole desktop release depend on secrets that do not exist.

build-android is now a hard prerequisite of release-shell. Its "Configure fail-closed Android signing" step (line 419) exits 1 unless all four of ANDROID_KEYSTORE_BASE64, ANDROID_KEYSTORE_PASSWORD, ANDROID_KEY_ALIAS, ANDROID_KEY_PASSWORD are non-empty, and the inspect step additionally requires ANDROID_CERTIFICATE_SHA256 to be a 64-hex digest.

gh secret list -R phase-rs/phase returns 29 secrets; none begins with ANDROID_. The workflow declares no environment:, so environment secrets cannot supply them either. With needs: [resolve-shell-ref, build-shell, build-android], a failed build-android skips release-shell entirely — so the next shell release publishes no GitHub release and no desktop artifacts, not merely no APKs.

The PR body's "Throwaway signed release build - PASS" is consistent with this: that validation used a local throwaway keystore, which proves the Gradle path works but says nothing about repository secret configuration.

Two ways out, either is fine:

  • Provision the five secrets before merge, or
  • decouple: drop build-android from release-shell's needs and attach the APKs opportunistically, so a missing-secret Android failure degrades to "no APKs this release" instead of "no release".

Caveat on my evidence: I can read repository and environment secrets but got a 403 on organization secrets. If these are provisioned org-wide and inherited, this finding dissolves — worth confirming explicitly, because the failure mode is otherwise invisible until a release is attempted.

Non-blocking — this test asserts against a reimplementation of the thing it is meant to verify.

resolve_capabilities re-derives Tauri's capability resolution in the test: the local default, remote URL matching via strip_suffix('*') + starts_with, the platforms filter, and the windows filter. capability_matrix_resolves_exact_local_remote_mobile_and_desktop_authority then checks capabilities/default.json against that model.

The consequence is that the test can only fail when the JSON disagrees with the model — never when the model disagrees with Tauri. The URL matching is the clearest gap: Tauri resolves remote.urls with urlpattern semantics, whereas the model does a naive prefix compare, so a pattern Tauri would reject or match differently still passes here. The permission-identifier assertions are also string comparisons against the raw JSON, not against resolved ACL entries, so a permission name that no permissions/*.toml actually defines would pass while failing at runtime.

The adjacent android_config_uses_tauri_rfc7396_merge_and_exact_typed_values test shows the pattern that does work here — it calls Tauri's real read_from(Target::Android, root) and deserializes into the real tauri::Config. If an equivalent real-resolver entry point isn't reachable from a unit test, a narrower assertion (every permission identifier in default.json resolves to a permissions/*.toml entry or a known plugin prefix) would carry more signal than the current matrix at a fraction of the size.

Non-blocking — source-text grep instead of a behavioral test.

This reads MenuPage.tsx as a string and asserts on its literal characters. PreferencesModal.android.test.tsx does the same thing. Both are decoupled from behavior in both directions:

  • False green: wrapping the guard in a helper ({shouldShowExit() && () keeps the intent but changes the string → test fails on a correct refactor. Conversely, changing the body to render the exit button unconditionally inside the guard keeps the string and the test stays green.
  • False red: prettier rewrapping to {isDesktopTauri() && <button …>} (no paren) breaks it with zero behavior change.
  • Unrelated coupling: expect(source).not.toContain("{isTauri() && (") fails if any future, unrelated isTauri() conditional is added to this file — a legitimate one, e.g. a Tauri-only-but-platform-agnostic affordance.

The PR already contains the right shape twice: BuildBadge.android.test.tsx and the new FullscreenButton.test.tsx cases mock ../../../services/platform and assert on rendered output. Both of these files convert to that in a few lines — render MenuPage with isDesktopTauri mocked false, assert the exit button is absent; mocked true, assert it is present and that clicking it reaches @tauri-apps/plugin-process.

This also matters beyond style: a source-grep test would not have caught the platform.ts:16 blocker, whereas a render test with the platform latch left unresolved would have.

Non-blocking — the rewrite is exactly equivalent to a two-line form.

The new shape duplicates checkForServiceWorkerUpdate() across two branches and needs two early returns to stay correct:

if (isDesktopTauri()) {
  checkForTauriUpdate();
  if (isBundledTauriOrigin()) return;
  checkForServiceWorkerUpdate();
  return;
}
if (!isTauri() || !isBundledTauriOrigin()) checkForServiceWorkerUpdate();

All four cases (desktop-bundled, desktop-remote, mobile-bundled, mobile-remote, web) collapse to:

if (isDesktopTauri()) checkForTauriUpdate();
if (!isTauri() || !isBundledTauriOrigin()) checkForServiceWorkerUpdate();

I checked the truth table both ways and they agree on every row. The three tests in BuildBadge.android.test.tsx pass unchanged against the shorter form.

const { t } = useTranslation();
const [isFullscreen, setIsFullscreen] = useState(!!document.fullscreenElement);
const desktopTauri = isDesktopTauri();
const mobileTauri = isTauri() && !desktopTauri;

Non-blocking — the name asserts something the expression does not establish.

mobileTauri reads as "this is a mobile Tauri shell," but isTauri() && !desktopTauri is really "Tauri, and not proven desktop." The platform latch has three outcomes — desktop, android/ios, and null (probe failed or returned something unrecognized) — and this expression folds the third into the second.

That conflation is what turns the platform.ts:16 blocker into a visible desktop regression rather than a silent capability loss: an existing shell that resolves null is classified mobileTauri, so if (mobileTauri) return null removes the fullscreen button outright.

Even after that blocker is fixed, naming the third state honestly (unknownOrMobileTauri, or exposing hostPlatform(): HostPlatform | null and matching on it) makes the fallback behavior legible at each call site instead of hiding it behind a boolean that claims more than it knows. MenuPage.tsx and PreferencesModal.tsx make the same collapse implicitly by testing only isDesktopTauri().

Non-blocking — hand edits to a generated file with no guard, and the README points at documentation that does not exist.

This file is tauri android init output carrying three local modifications that are load-bearing for the release pipeline: the signingConfigs block (line 74), strictAndroidVersionCode (line 16), and the fail-closed tasks.configureEach release guard (line 118). Running tauri android init — the reflexive move for anyone whose Android build looks stale — overwrites all three silently. The result is a release build that produces an unsigned or debug-signed APK rather than failing, since the guard that enforces fail-closed is itself part of what gets clobbered.

The README addition says regeneration "is supported only by a documented deterministic reapply process," but no such document is in the diff and I found none in the repo. Right now the protection is a prose warning in a README section a contributor may never open.

A mechanical guard would cost a few lines and is exactly the kind of thing the Rust test suite here is already set up for — assert that app/build.gradle.kts contains the signing config and the fail-closed task, the way lib.rs already pins tauri.conf.json's window shape. Worth noting the asymmetry: this PR adds a source-grep test to protect a one-line JSX guard in PreferencesModal.tsx, but leaves the far more clobber-prone Gradle file unguarded.

Related: the major * 1_000_000 + minor * 1_000 + patch mapping now exists three times — strictAndroidVersionCode here, android_version_code in shell-release.yml, and Tauri's own default derivation that actually feeds tauri.properties. Two of the three are assertions about the third, so they are not strictly redundant, but a drift in Tauri's default would be caught only as a CI grep -F failure with no explanation.

Non-blocking — the gate rewrite tightens four unrelated pre-existing jobs.

The previous loop treated skipped as a pass for every job. The new required_results list demands exactly success from rust-lint, rust-test, card-data-gate, wasm-check and android-debug-apk, while tauri-check and draft-pools get bespoke skipped-tolerant branches.

The rewrite isn't needed for the stated goal. android-debug-apk has no if: condition, so it never reports skipped; adding it to the existing loop would have gated it identically in one line. What the rewrite actually changes is the contract for four jobs this PR doesn't otherwise touch — they now fail the gate if they are ever skipped, e.g. if a path filter or a conditional is added to any of them later.

I verified this is currently harmless: none of those four has an if: today, so the behavior is identical in practice. It is scope creep rather than a defect, but it means a future "only run card-data when card files change" optimization would break the gate in a way that reads as a test failure.

(The tauri-check comment is accurate — if: ${{ false }} at line 650 is pre-existing on the base commit.)

// every existing and future external link in the app works without changes.
// The release and preview origins stay inside a remote-origin shell so channel
// navigation keeps its service worker and Tauri IPC context.
// External link routing for Tauri. A capture-phase document handler covers

Non-blocking — the replacement comment drops the rationale, not just the length.

The removed block explained why the design is what it is: that <a target="_blank"> is silently swallowed inside a Tauri webview, that capture-phase + closest("a") was chosen over per-callsite onClick so future links work without changes, and that modifier-clicks are deliberately routed too because "open in new tab" has no meaning in a webview. The new three lines describe what the handler does, which is already legible from the code.

That rationale is what stops the next reader from "simplifying" this into per-link handlers or re-adding a modifier-key bail-out. Worth keeping, especially now that the behavior surface grew — the new !isOpenableExternalUrl(href) branch actively preventDefault()s non-HTTP(S) schemes (mailto:, tel:, protocol-relative //host/path), which is a deliberate deny that has no explanation anywhere in the file. I confirmed the app currently ships no mailto:/tel: anchors, so there is no live regression — but a future one would fail silently and the code says nothing about why.

Smaller point on the same change: openExternal.ts now imports its URL authority (isOpenableExternalUrl) from externalLinks.ts, i.e. the general-purpose opener depends on the DOM click-interception module. The dependency reads backwards; the validator would sit more naturally next to openExternal or in platform.ts.
