TypeDoc for @softcose/softchat

The /kotlin/ route is the generated symbol output for the Kotlin declarations shipped in the Android AAR. Android-specific threading, Rust-owned SQLite, packaging, files, lifecycle, and device performance guidance remains visible in the Android tab throughout the cookbook.

Verified workflows

The repository smoke/package suites compile and execute the authored surfaces, including complex multi-family workflows:

The site uses shortened recipes for clarity. The Android selector always renders the complete callable Kotlin recipe together with any Android integration note, so no navigation to a separate language tab is required. These checked-in consumers are executable evidence that generated internals are not required.

The assembled capability matrix records implementation, interoperability evidence, and release status independently for every target.

Performance reports

Contextual cards appear only beside operations present in the accepted benchmark corpus. They show median duration, p95 duration, equivalent single-thread calls per second, payload throughput where meaningful, allocations where available, comparison with the frozen old library where available, environment, and confidence.

Use the performance analysis to find relative median gaps, inspect p95 amplification, and see which evidence gates remain. The standalone audit reports preserve the exact records:

These are descriptive results for the recorded runner or device. They are not universal latency guarantees.
