/**
 * Hard ceiling on reported issues. The decoder runs on the untrusted side of
 * the IPC boundary and its issue list is serialized straight into the error
 * response, so an input that is *wrong in many places at once* used to cost
 * far more memory than the input itself: one 8 MB frame carrying a two-million
 * entry `capabilities` array produced roughly four million issue objects (an
 * `invalid_value` and a duplicate report per entry), each holding its own path
 * and message string.
 *
 * A caller only ever acts on the first few issues, so the list is truncated
 * with an explicit marker instead of being allowed to outgrow its input. Every
 * issue is created through `issue()`, which makes this the single choke point.
