Echo Protocol

# Echo Protocol v0.4.0-alpha — False Memories

The world no longer remembers only what happened.
It begins remembering what never happened.

## Added

- False Memories that begin with authentic player recordings before deviating
- Panic Imprints based on dangerous moments survived by the player
- Rare Peripheral Echo sightings
- Audio Residue from familiar but empty locations
- Borrowed Habits for The Original
- Adaptive Event Director 2.0
- Six new hidden advancements
- New administrator and testing commands

## The Original Reworked

The Original has received a complete movement and behavior overhaul:

- Smooth continuous walking
- Acceleration and deceleration
- Natural body and head rotation
- Bounded local waypoint planning
- Observation-aware reactions
- Stuck detection and recovery
- Distinct behavior for all nine Original event types
- Real position-driven walking animation
- Purposeful pauses and bounded endings

## Improved

- Event pacing and repetition prevention
- Familiar-location behavior
- Safe movement around obstacles
- Multiplayer privacy
- Configuration migration
- Disconnect and dimension-change cleanup

## Safety

- No block modification
- No inventory or container modification
- No chunk force-loading
- No destructive Panic Imprint recreation
- Hardcore-safe defaults
- Private Echo data remains server-authoritative

## Requirements

- Minecraft Java Edition 1.21.1
- Fabric Loader 0.16.14 or newer
- Fabric API
- Java 21
- Installed on both client and server

## Known Limitations

- New event histories are session-scoped
- The Original uses bounded local navigation rather than full mob pathfinding
- Complex multi-floor paths, ladders, closed doors, and long routes may trigger a safe fallback
- Sound design primarily uses compatible vanilla sound events
