Substrate Event Bus (SEB)
The universal signaling layer of the EcoEchoSystem#
The Substrate Event Bus (SEB) is the EcoEchoSystem’s cross‑domain communication system.
It is the mechanism through which Structure (S), Activation (E), and Relational Time (R) changes propagate across agents, domains, and scales.
Where the Triadic Substrate defines the grammar, and Regime Awareness/Transitions define the dynamics, the SEB defines the flow of information — the substrate’s way of saying:
“Something changed. Here’s how it affects everything else.”
The SEB is the backbone of cross‑domain coherence.
Purpose#
The Substrate Event Bus exists to:
- propagate activation spikes
- broadcast structural changes
- signal regime transitions
- coordinate cross‑domain responses
- support multi‑scale simulation
- maintain substrate‑level coherence
Without the SEB, domains would drift apart and the EcoEchoSystem would lose its unified behavior.
Core Concepts#
1. Event Types#
The SEB supports several canonical event types, each aligned with the triadic substrate:
a. Structural Events (S‑Events)#
Triggered when:
- identity changes
- architecture reorganizes
- boundaries shift
- invariants update
These events anchor long‑arc coherence.
b. Activation Events (E‑Events)#
Triggered when:
- energy spikes
- volatility increases
- emotional/market/physical activation rises
- instability emerges
These events often precede regime transitions.
c. Relational‑Time Events (R‑Events)#
Triggered when:
- developmental arcs shift
- memory integrates
- temporal context changes
- long‑arc trajectories realign
These events shape identity and evolution.
d. Regime Events (REG‑Events)#
Triggered when:
- entering a regime
- exiting a regime
- approaching a boundary
- cascading transitions begin
These are the substrate’s most consequential signals.
2. Event Payloads#
Each event carries:
- S/E/R deltas (what changed)
- regime context
- scale context (agent, group, city, civilization)
- domain context
- causal metadata
Payloads allow domains to respond intelligently.
3. Event Propagation#
Events propagate:
- vertically (agent → group → city → civilization)
- horizontally (psychology ↔ economics ↔ governance ↔ AI ↔ biology ↔ physics)
- temporally (past → present → future via relational‑time corrections)
Propagation respects:
- dimensional invariants
- regime boundaries
- stability constraints
4. Event Prioritization#
The SEB prioritizes events based on:
- activation intensity
- structural importance
- regime proximity
- cross‑domain impact
- multi‑scale relevance
High‑activation events propagate fastest.
5. Event Filtering#
Domains can filter events by:
- scale
- type
- intensity
- regime
- domain relevance
Filtering prevents overload and maintains coherence.
SEB Across Domains#
Psychology#
- emotional spikes
- cognitive shifts
- identity transitions
Economics#
- volatility surges
- resource‑flow changes
- market regime shifts
Governance#
- legitimacy changes
- institutional stress
- societal activation
Physics#
- energy transitions
- field reconfigurations
- phase changes
Biology#
- metabolic shifts
- environmental stress
- adaptation signals
AI#
- learning‑rate spikes
- stability warnings
- architecture transitions
All domains communicate through the same substrate bus.
SEB in Multi‑Scale Simulation#
The SEB enables:
- cascading transitions
- cross‑domain coupling
- predictive modeling
- stability analysis
- civilization‑level dynamics
It is the substrate’s circulatory system.
Design Principles#
The SEB follows five core principles:
- Triadic Alignment — all events must be S/E/R coherent
- Regime Awareness — events carry regime context
- Dimensional Stability — propagation respects vST invariants
- Cross‑Domain Compatibility — all modules can subscribe
- Multi‑Scale Continuity — events propagate across scales
