# 0008 — Native processors and source release preparation
Status: accepted, Phase 9.
Add a versioned copied C descriptor with control-thread prepare/destroy and
single-owner realtime reset/process. Prove effects/sources in the existing graph,
with two independent mono instances for stereo, and event instruments rendered
through the public instrument-source buffer boundary. Keep trusted code statically
linked. Native project serialization and graph event ports need more contracts;
reject unsupported saves without replacing files. Defer LV2/CLAP/VST3 after a
concrete evaluation rather than linking SDKs speculatively.
Keep format v4 and test migration plus process-crash/write-failure behavior.
Provide deterministic source exports and optimized release builds, staged
core/GUI installation, exact uninstall and installed C/C++ consumer tests. Use
Python standard-library tools only for packaging/testing; no application runtime
dependency or system changes. Document dependency licenses, Linux routing and
measured offline performance separately from unverified hardware/endurance.
See NATIVE_API.md, PLUGIN_HOSTING.md, RELEASING.md and RECOVERY.md.
