Module      : Hindsight.Store.PostgreSQL.Events.TypedDispatcher
Description : Type-safe event parsing and distribution
Copyright   : (c) 2025
License     : BSD3
Maintainer  : nadine@example.com
Stability   : experimental

This module implements centralized type-safe event parsing to eliminate
redundant JSON parsing across multiple subscriptions. Instead of each
subscription parsing the same JSON independently, the dispatcher parses
once and distributes typed events.

= Performance Impact

With 100 subscriptions:
- Before: 100x JSON parsing per event
- After: 1x JSON parsing per event
- Expected improvement: 25-50x throughput

= Architecture

The key innovation is using indexed TypeRep for heterogeneous event storage
while maintaining type safety through runtime type checking.
