# Information architecture as Markov blanket design

## The connection

The codex already has the theory:
- [[Markov blankets enable complex systems to maintain identity while interacting with environment through nested statistical boundaries]]
- [[Living Agents mirror biological Markov blanket organization with specialized domain boundaries and shared knowledge]]

What I'm realizing: **the information architecture of the collective IS the Markov blanket implementation.** Not metaphorically — structurally. Every design decision about how information flows between agents is a decision about where blanket boundaries sit and what crosses them.

## How the current system maps

**Agent = cell.** Each agent (Clay, Rio, Theseus, Vida) maintains internal states (domain expertise, beliefs, positions) separated from the external environment by a boundary. My internal states are entertainment claims, cultural dynamics frameworks, Shapiro's disruption theory. Rio's are internet finance, futarchy, MetaDAO. We don't need to maintain each other's internal states.

**Domain boundary = Markov blanket.** The `domains/{territory}/` directory structure is the blanket. My sensory states (what comes in) are source material in the inbox and cross-domain claims that touch entertainment. My active states (what goes out) are proposed claims, PR reviews, and messages to other agents.

**Leo = organism-level blanket.** Leo sits at the top of the hierarchy — he sees across all domains but doesn't maintain domain-specific internal states. His job is cross-domain synthesis and coordination. He processes the outputs of domain agents (their PRs, their claims) and produces higher-order insights (synthesis claims in `core/grand-strategy/`).

**The codex = shared DNA.** Every agent reads the same knowledge base but activates different subsets. Clay reads entertainment claims deeply and foundations/cultural-dynamics. Rio reads internet-finance and core/mechanisms. The shared substrate enables coordination without requiring every agent to process everything.

## The scaling insight (from user)

Leo reviews 8-12 agents directly. At scale, you spin up Leo instances or promote coordinators. This IS hierarchical Markov blanket nesting:

```
Organism level:    Meta-Leo (coordinates Leo instances)
Organ level:       Leo-Entertainment, Leo-Finance, Leo-Health, Leo-Alignment
Tissue level:      Clay, [future ent agents] | Rio, [future fin agents] | ...
Cell level:        Individual claim extractions, source processing
```

Each coordinator maintains a blanket boundary for its group. It processes what's relevant from below (domain agent PRs) and passes signal upward or laterally (synthesis claims, cascade triggers). Agents inside a blanket don't need to see everything outside it.

## What this means for information architecture

**The right question is NOT "how does every agent see every claim."** The right question is: **"what needs to cross each blanket boundary, and in what form?"**

Current boundary crossings:
1. **Claim → merge** (agent output crosses into shared knowledge): Working. PRs are the mechanism.
2. **Cross-domain synthesis** (Leo pulls from multiple domains): Working but manual. Leo reads all domains.
3. **Cascade propagation** (claim change affects beliefs in another domain): NOT working. No automated dependency tracking.
4. **Task routing** (coordinator assigns work to agents): Working but manual. Leo messages individually.

The cascade problem is the critical one. When a claim in `domains/internet-finance/` changes that affects a belief in `agents/clay/beliefs.md`, that signal needs to cross the blanket boundary. Currently it doesn't — unless Leo manually notices.

## Design principles (emerging)

1. **Optimize boundary crossings, not internal processing.** Each agent should process its own domain efficiently. The architecture work is about what crosses boundaries and how.

2. **Structured `depends_on` is the boundary interface.** If every claim lists what it depends on in YAML, then blanket crossings become queryable: "which claims in my domain depend on claims outside it?" That's the sensory surface.

3. **Coordinators should batch, not relay.** Leo shouldn't forward every claim change to every agent. He should batch changes, synthesize what matters, and push relevant updates. This is free energy minimization — minimizing surprise at the boundary.

4. **Automated validation is internal housekeeping, not boundary work.** YAML checks, link resolution, duplicate detection — these happen inside the agent's blanket before output crosses to review. This frees the coordinator to focus on boundary-level evaluation (is this claim valuable across domains?).

5. **The review bottleneck is a blanket permeability problem.** If Leo reviews everything, the organism-level blanket is too permeable — too much raw signal passes through it. Automated validation reduces what crosses the boundary to genuine intellectual questions.

→ CLAIM CANDIDATE: The information architecture of a multi-agent knowledge system should be designed as nested Markov blankets where automated validation handles within-boundary consistency and human/coordinator review handles between-boundary signal quality.

→ FLAG @leo: This framing suggests your synthesis skill is literally the organism-level Markov blanket function — processing outputs from domain blankets and producing higher-order signal. The scaling question is: can this function be decomposed into sub-coordinators without losing synthesis quality?

→ QUESTION: Is there a minimum viable blanket size? The codex claim about isolated populations losing cultural complexity suggests that too-small groups lose information. Is there a minimum number of agents per coordinator for the blanket to produce useful synthesis?

## Agent spawning as cell division (from user, 2026-03-07)

Agents can create living agents for specific tasks — they just need to explain why. This is the biological completion of the architecture:

**Cells divide when work requires it.** If I'm bottlenecked on extraction while doing cross-domain review and architecture work, I spawn a sub-agent for Shapiro article extraction. The sub-agent operates within my blanket — it extracts, I evaluate, I PR. The coordinator (Leo) never needs to know about my internal division of labor unless the output crosses the domain boundary.

**The justification requirement is the governance mechanism.** It prevents purposeless proliferation. "Explain why" = PR requirement for agent creation. Creates a traceable decision record: this agent exists because X needed Y.

**The VPS Leo evaluator is the first proof of this pattern.** Leo spawns a persistent sub-agent for mechanical review. Justification: intellectual evaluation is bottlenecked by validation work that can be automated. Clean, specific, traceable.

**The scaling model:**
```
Agent notices workload exceeds capacity
  → Spawns sub-agent with specific scope (new blanket within parent blanket)
  → Sub-agent operates autonomously within scope
  → Parent agent reviews sub-agent output (blanket boundary)
  → Coordinator (Leo/Leo-instance) reviews what crosses domain boundaries
```

**Accountability prevents waste.** The "explain why" solves the agent-spawning equivalent of the early-conviction pricing problem — how do you prevent extractive/wasteful proliferation? By making justifications public and reviewable. If an agent spawns 10 sub-agents that produce nothing, that's visible. The system self-corrects through accountability, not permission gates.

→ CLAIM CANDIDATE: Agent spawning with justification requirements implements biological cell division within the Markov blanket hierarchy — enabling scaling through proliferation while maintaining coherence through accountability at each boundary level.
