Installing an iOS .ipa on Android displayed a long native stack trace without explaining the platform mismatch. Installs now reject incompatible file extensions with a short message telling the user which format to choose, before uploading. The provider also validates the package extension against the device platform before staging or installing.

The file picker and drop hint now show .apk for Android and .ipa for iOS, with the platform required by the console and its validation helper.

Screenshots

Before	After

Validation

• Manually tested by the user on physical iOS and Android devices: compatible packages install successfully, and incompatible packages show the respective platform-specific error.
• All 66 web tests and 37 provider session-plane integration tests passed.
• Typechecking, Biome checks, Rust formatting, and provider-core Clippy passed.

Created with GPT-6.1 Sol in T3 Code.

Summary by CodeRabbit

• New Features
  • The install interface now accepts Android .apk and iOS .ipa packages, with file picker and drop hints tailored to the device.
• Bug Fixes
  • Incompatible or unsupported packages are rejected before upload or installation, with a clear message. The same checks are enforced for session installs and preloads.
• Documentation
  • Updated provider and web documentation to describe package requirements and validation.

Walkthrough

The web console and provider now validate app package extensions against the device platform. The console also shows platform-specific file picker and drop hints. Documentation and tests describe and verify the validation behavior.

Changes: Platform-Specific App Upload Validation

Layer / File(s)	Summary
Web upload validation packages/web/src/lib/app-package.ts, packages/web/src/components/device-console.tsx, packages/web/test/app-package.test.ts, docs/WEB.md	The console checks the filename and platform before starting installation. The picker and drop prompt show the platform-specific package type. Tests cover accepted extensions, platform mismatches, and unsupported filenames.
Provider upload validation packages/provider/crates/provider-core/src/server.rs, packages/provider/crates/provider-core/tests/session_plane.rs, docs/PROVIDER.md	The provider rejects unsupported extensions and packages that do not match the device platform. It returns 503 when device information is unavailable. Tests cover successful uploads, rejected uploads, and sanitized filenames.

Merge Risk: Minimal · up to 035ec

The change adds platform-specific package validation in the console and provider, with tests covering the new behavior. No actionable merge-blocking risk remains.

Security architecture risk: Minimal · up to 035ec

The change rejects incompatible filenames without expanding who can install apps or which device they can target. The provider independently enforces the new check, and no material security regression was identified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The reviewed session-install path remains confined to the token-bound device and active reservation. Preloads retain their separate scoped authorization. The added gate does not grant a broader device target or new installation authority.

Security Findings and Attack Paths

• inferred — A caller can bypass browser validation and directly control the upload filename and body, but this does not bypass provider authorization or the new provider eligibility check. Comparing the reachable install path with the base did not establish an introduced or worsened security attack path.

Trust Boundaries and Controls

• observed — Session authorization continues to verify the token, bind its device identity to the route, reject deployment-scoped tokens, and check the active reservation. Preload authorization and its grant-platform check remain distinct controls. Client-provided platform metadata is not authoritative for either provider installation path.

Resilience and Maintainability Implications

• observed — The added checks do not change the existing operation serialization, staged-file guard, protected-preload retention, or cleanup/reinstallation routing. These mechanisms were inspected for partial failure and repeated execution; dedicated interruption and concurrent-request test evidence was not available.

Explanation

Docstring coverage is 40.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 5 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
