// CLAUDE: Refactor this package into the constants package. Rename all constats moved to the constants package so that they all have a suffix Protocol.... e.g. MessageDelimiter => ProtocolMessageDelimiter, and so on.
// Package protocol defines the communication protocol constants used throughout
// the DTail distributed log processing system. This package contains the
// delimiter characters and protocol version that enable proper message parsing
// and serialization between DTail clients and servers.
//
// The protocol uses specific Unicode characters as delimiters to avoid conflicts
// with typical log file content while maintaining human readability during debugging.
package protocol

// ProtocolCompat defines the compatibility version string used to ensure
// client-server protocol compatibility. Both client and server must have
// matching protocol versions to communicate successfully.
ProtocolCompat string = "4.1"
// MessageDelimiter is the byte used to separate individual protocol messages
// in the communication stream. Uses the Unicode "not sign" (¬) character to
// minimize conflicts with log file content.
MessageDelimiter byte = '¬'
// FieldDelimiter separates fields within a single protocol message.
// Uses the pipe character (|) for field separation within structured messages.
FieldDelimiter string = "|"
// CSVDelimiter is used when outputting results in CSV format, providing
// standard comma-separated value formatting for tabular data export.
CSVDelimiter string = ","
// AggregateKVDelimiter separates key-value pairs within MapReduce aggregation
// messages. Uses the Unicode "colon equals" (≔) character for clear separation
// of keys from their corresponding values in aggregation results.
AggregateKVDelimiter string = "≔"

// such as separating metadata from data or different aggregation groups.
// Uses the Unicode "double vertical line" (∥) character.

// single composite key when performing GROUP BY operations in MapReduce queries.
