Summary

add the new @tanstack/db-capacitor-sqlite-persisted-collection package with the Capacitor SQLite driver, persistence factory, tests, and README
move the native runtime harness into packages/db-capacitor-sqlite-persisted-collection/e2e/app and run the full persisted collection conformance suite inside a real Capacitor iOS app
extend the shared native harness to Android with a host runner that builds, installs, launches, and reads back native SQLite test results from the app sandbox

Restore db-electron-sqlite-persisted-collection with IPC bridge, ElectronCollectionCoordinator for cross-window sync, and full e2e test suite. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add a Capacitor SQLite runtime wrapper so persisted collections can reuse the shared core adapter and test coverage pattern across runtimes. Made-with: Cursor

Move the Capacitor persisted-collection runtime harness into the package, run the full conformance suite in a native iOS app, and share the suite registration lifecycle across the shimmed and native e2e paths. Made-with: Cursor

Extend the shared Capacitor test app to support Android, add a host runner that boots or reuses an emulator and reads the native SQLite results database, and document the new Android e2e workflow. Made-with: Cursor

Pass the detected Android SDK through native build commands, guard the Android runner's piped subprocess output, and align the shared harness teardown hook with the e2e contract's real cleanup path. Made-with: Cursor

PR Review: #1363 — feat: add Capacitor SQLite persisted collection package

Overall

Solid PR. The package structure, public API, test coverage (all four contract suites + bespoke tests + native e2e on both iOS and Android), and persistence wiring all follow established patterns correctly. The README has useful Capacitor-specific platform notes.

Issues to address

capacitor-sqlite-driver.ts:28 — Missing optional chaining on process.versions

return typeof process.versions.node === `string`

In Capacitor's webview, process may be polyfilled (e.g., by Vite/webpack) but process.versions could be undefined, which would throw at runtime. Should be process.versions?.node.

Worth considering

close() always closes the database — Since the caller creates and owns the SQLiteDBConnection externally, having the driver's close() unconditionally call database.close() could surprise callers who share a connection across multiple drivers. Consider either documenting this or leaving close() as a no-op and letting the caller manage the connection lifecycle.
e2e/app/src/runtime-vitest.ts (545 lines) — This custom test runner is a significant piece of infrastructure. If other native runtime packages need similar e2e harnesses in the future, it may be worth extracting into a shared package rather than duplicating.
tsconfig.json includes "jsx": "react" — No JSX in this package; unnecessary.

Summary

Approve with one fix — the process.versions?.node optional chaining bug. The rest are minor suggestions.
