"""Messaging topology constants + builders (REQ-021, dcy-006 OQ-2).
|
|
|
|
Three patterns:
|
|
1. slots RPC — direct queue `trex.slots.req`, reply via amq.rabbitmq.reply-to
|
|
2. intent RPC — direct queue `trex.intent.req`, reply via amq.rabbitmq.reply-to
|
|
3. events — topic exchange `trex.events`, routing key {event_type}.{strategy_id}.{symbol}
|
|
|
|
Mapping principle: requests carry filter/spy in *payload*; events carry
|
|
strategy_id/symbol in the *routing key* so brokers can filter per-strategy
|
|
queues with patterns like `*.{strategy_id}.#`.
