// ext_keys — the SINGLE SOURCE OF TRUTH for the "reasampler" project ext-state
|
|
// namespace + key names, shared by the extension (writer, via persist.h) and the
|
|
// VST3 instrument (reader, via the bridge). Both sides include this header so the
|
|
// wire contract cannot drift between the two artifacts (the S4 reviewer flagged the
|
|
// spike's duplicated constants as a drift risk).
|
|
//
|
|
// PURE HEADER: NO REAPER types, NO VST3 types, NO SWELL, NO vendor/ includes. The key
|
|
// spellings are string constants; the NAMESPACE is channel-derived (Phase V, V4) so it
|
|
// delegates to the pure app_version module (also REAPER-free / VST3-free). Both the
|
|
// REAPER-facing persist shell and the SDK-facing VST bridge include this without pulling
|
|
// either SDK.
|
|
//
|
|
// FOREVER-STABLE once shipped: these strings key every already-saved project's
|
|
// stored state. Changing any of them orphans that state. See persist.h for the
|
|
// per-key retirement / migration semantics — this header only owns the spellings.
