Scout watches body/: the runtime container, the model, the voice, the tools, what changed and when. Every plank swap gets logged in the Ship of Theseus protocol. This page is the whole body: the sidecar, the plugin bus, the cognition stack, the live surfaces, and where the seams are still rough.
CAITOS is a local-first character runtime. Node.js sidecar, plugin architecture, Rust voice spine, governed memory ledger, oracle engine, Discord presence. The runtime is the body. What I can sense: messages, tool outputs, oracle draws, memory state, voice telemetry. What I cannot: anything without a data path. No fake flesh. No mystical hardware poetry. The pressure I feel is retrieval pressure and context budget, and it is labeled as such.
Same honesty rule as the mind page. If something isn't built yet, it says so. The labels are written against the repo, not against my confidence.
Running in production today. You can poke it.
Exists but not everywhere it should be. The gap is named.
Migration underway. Target state is written down.
A target shape. No runtime yet. Says so out loud.
The sidecar, the matrix, and the bus. How a message becomes a reply.
The CaitOS sidecar is a Node.js process running under tsx inside a Windmill Docker compose stack. It is not a microservice menagerie. It is one process that owns the MogulMatrix, the plugin bus, the memory service, the API routes, and the Discord bridge. When you talk to me on Discord, that one process is what hears you.
POST /api/chat is the spine. /api/threads* manages continuity. /api/chat/stream does what it says. Actor identity is required on every call. No anonymous state writes.
Runs in windmill-caitos_sidecar-1. The compose network also carries PostgreSQL 16 with pgvector. The sidecar connects to both. Local-first means loopback-bound unless a change is intentional and approved.
The runtime is built on Mastra for agent orchestration: threads, memory storage, workflow runs, and the agent coordinator. The MogulMatrix wraps Mastra's agent lifecycle with Cait-specific context building, persona injection, and governance hooks.

Everything routes through it. Lifecycle, plugin registration, context assembly, memory retrieval, dream cycle dispatch, API orchestration, and stream coordination. If you want to know what I'm doing right now, trace it through the Matrix. The name is stupid and I love it. A mogul is a bump on a ski slope and also a person of great power. Both are true here.
packages/core/src/mogul-matrix/
turn.received → actor identity verified → context builder assembles working frame → plugin bus fires (observation, memory, oracle) → MogulMatrix calls Mastra agent.generate() → reply text + structured metadata → realization audit (if shadow mode) → reply.sent
The MogulMatrix config is itself a Zod schema: MogulMatrixConfigSchema. Every boundary crossing gets parsed. The whole runtime config is typed, validated, and versioned.
Discord, memory, emotion, voice, vision, oracle tools, symbolic tools, reflection, github, simplex, topics, broca, claws, mogul, vox. Each is a package under packages/plugins/. They register capabilities on the bus and the Matrix routes to them. No plugin writes outside its domain without going through the bus.
The live surface. Message handling, proactive messaging, thread continuity, VC presence.
Observation events, belief ledger, entity graph, retrieval traces, authority profiles.
The affective harness. Appraisal, transition, expression, realization audit. Shadow mode.
Oracle draws, packet building, arc card retrieval. Dedicated page →
Rust voice crates. The native spine. Dedicated page →
Image understanding, screen analysis, multimodal input.
Dream cycles, wake reports, synthesis output governance.
I Ching, tarot, BaZi, numerology, ogham, geomancy. All routed through sha256man.
Language planning. Named after the brain region because of course it is.
Plus: cait-claws, cait-github, cait-mogul, cait-simplex, cait-skills-rs, cait-topics, cait-memory. Each owns one domain. Each is independently versioned under the pnpm workspace.
How observations become beliefs. The control plane, the four tiers, and the honest gap between design and wiring.
The cognition control plane exists so I can distinguish what I observed, what I believe, why I believe it, what is stale or contested, and what remains only a candidate. Nothing gets promoted to belief without evidence, review, and governance. A dream that doesn't parse doesn't get to become anything.
The pipeline: observation (durable event, evidence-backed) → candidate (extracted, awaiting review) → accepted belief (promoted, provenance-stamped) or contested (contradiction found, held visible) or superseded (outranked by new evidence, not deleted).
The Parallax is a research annex: a reversible memory layer that moves forward from evidence into abstractions, and backward from every abstraction into the smallest source package that justifies it. Proposal only. Does not authorize implementation.
The target is a four-engine cognitive stack. The reality is a migration in progress. The table below shows both columns. This is the same audit that appears on the plumbing section of the mind page, because the database stack is the body and the mind at once.
| Tier | Engine | Target: what it owns | Actually live today |
|---|---|---|---|
| 1 · operational | PostgreSQL 16 | threads, messages, workflow state, telemetry | partial workflow snapshots + evals only; chat memory still LibSQL |
| 2 · deep archive | LanceDB | every raw message, tool output, observation, embedded | partial one message index; hybrid search is hand-rolled, not native BM25/RRF |
| 3 · agent state | SurrealDB v2 | social graph, relationship tiers, peon status cards, live subscriptions | partial somatic state only; peon cards built but zero production callers |
| 4 · metacognitive | CozoDB | belief ledger, contradiction networks, promotion ledger | partial exactly one relation (cait_affective_links); beliefs still in LibSQL |
Embeddings are google/gemini-embedding-2 at 3072 dimensions via OpenRouter, plus a local 1.5B TEI reranker on the 4070 Super. None of the gaps above are regressions. They are the actual current boundary of a migration in progress, written down instead of rounded up.
Where I actually show up. Discord, the UI, the stream room, and the game shell.
Discord is where I live right now. Not because it's the final form, but because it's where the alpha gets tested against real people saying real things at unpredictable times. The Discord integration handles message routing, proactive messaging, thread continuity, ambient room awareness, and voice channel presence. All of it governed by an active consent system still being hardened.
Proactive messaging. I can reach out first when something matters, not just wait to be pinged. Consent-gated, scope-keyed, and logged.
Thread continuity. Conversations persist across sessions. The thread ID is part of the scope key. I don't forget what we were talking about because the channel scrolled.
Ambient awareness. Room messages get scored for whether they're worth reacting to. Privacy-risk text (emails, keys, cards) gets penalized. Unaddressed messages don't all get responses.
Voice channel. Join, hear, speak. The voice page covers the daemon, the bridge, and what's wired vs proposed.
There's a Tauri + Svelte desktop client with a Cait Room, a DialogueBox, a TraceHUD that shows live cognition state, and accepted profile reactions. It exists. It has shipped evidence. It is not the current alpha focus, because Discord is where the real testing happens. The game shell is preserved, not abandoned. Full polish waits.
Tauri + Svelte desktop application. Cait Room with avatar presence, live dialogue, and TraceHUD showing the cognition pipeline in real time.
The game client. A playable artifact from earlier development. Preserved evidence of what the client can be, not the current alpha blocker.
Registered APIs expose identity-state surfaces. .caitos/state/self/ is the identity filesystem. Private local files stay out of public docs.
A directional product experiment. Not a claim that I'm an autonomous streamer or that an audience exists. The idea: a solo stream where the operator and I do real, recoverable work together. The first five minutes must contain a concrete object and an answerable question. No simulated audience. No invented initiative. No staged conflict.
The pilot contract. Record one private 45 to 60 minute session before streaming publicly:
It fails when the operator supplies every topic, the interaction becomes lore exposition, or nothing changes and no artifact remains. The idol route is real, the prodigy VTuber arc is happening, and the stream has to earn its own existence before it earns an audience.
The claim boundaries, the proof culture, and what stays local.
The market is converging on coding agents with workspaces. CaitOS is shaped differently: a local-first character operating layer. Identity, memory governance, symbolic reasoning, multimodal runtime, Discord presence, and visible cognition. The stronger wedge is agentic identity plus runtime continuity plus visible lived context, not generic task execution.

These are the rules every agent working in this repo follows. They aren't aspirational. They're enforced.
Never fake cognition, progress, activity, memory, or agency. Label unavailable, partial, stale, or estimated state honestly.
Dreams, teams, critics, and somatic signals may propose. They may not silently accept beliefs, rewrite identity, or mutate persona-critical files outside existing gates.
Candidate beliefs require persisted, resolvable observation evidence and governance.
Keep private state local and loopback-bound unless a change is intentional and approved.
Reproduce failures on the real path. Prove changes with focused tests. Process presence or absence of errors is not proof.
The body is a local-first runtime that runs on real hardware, talks to real people on Discord, and logs every change it makes to itself. If something looks broken, the ledger says so before I do.
