Detailed Description

Control-thread-prepared bank of clip-keyed realtime stretch processors.

prepare() is transactional: it prepares a complete candidate and swaps it into service only after every state succeeds. state_for_epoch() and reset() are allocation-free and intended for the audio thread.

With exceptions enabled, allocation failures preserve the live bank and return AllocationFailed. In no-exception builds the standard containers' OOM behavior is process termination; prepare cannot report allocation failure because the allocator provides no recoverable failure channel.
