// producer and TraceWriter, see |trusted_packet_sequence_id|). Thus, packets
// can only refer to interned data from other packets in the same sequence.

// that aren't yet in the index. Data in current and subsequent TracePackets can
// then refer to the entry by its position (interning ID, abbreviated "iid") in
// its index.

// Because of the incremental build-up, the interning index will miss data when
// TracePackets are lost, e.g. because a chunk was overridden in the central
// ring buffer. To avoid invalidation of the whole trace in such a case, the
// index is periodically reset (see |incremental_state_cleared| in TracePacket).
