Phase 8, completing milestone M1. A user message is stored and appended as an observation event carrying trust, actor, channel and reference. The perceive process analyses it deterministically (intent, introspection kind, entities, claims, urgency) and, within the per-cycle model allowance, enriches it through the perceive prompt. Its handler writes a perception event, an episodic memory with participants, turns claims into beliefs whose evidence is the message, and builds a response intent from state: beliefs and memories for the topic, evidence rows for why-questions, the uncertain band, contested beliefs and their links, recent learning, status changes, and honest declines for subsystems that do not exist yet or for requests with no capabilities. The respond prompt phrases the intent when a model is assigned; otherwise the reply is a direct rendering of the intent. response_generated cites the message, the perception, every belief and memory used, the episode and the model call. API: conversations, messages with optional wait, one-shot ask; chat UI with live refresh and a per-reply intent view. Sample mind Dani as a strictly decoded seed document with an import endpoint and noemactl mind import. tests/m1 drives all fourteen milestone steps including restart.

# Noema
|
||
|
||
**Noema is a persistent, inspectable artificial cognitive runtime.**
|
||
|
||
It is an always-running daemon that hosts one or more *minds*: cognitive entities with their own identity, personality, memories, beliefs, goals, drives, affective state and history. Minds perceive events, compete internally for attention through a global workspace, retrieve and consolidate memories, form and revise beliefs with explicit evidence, make predictions and learn from prediction error, and act only through a policy-governed capability layer. Everything of consequence is recorded as an immutable cognitive event, so an operator can always ask *why*.
|
||
|
||
Language models are used by Noema as **cognitive service providers** for language understanding, concept extraction, hypothesis generation and narrative. They are not the mind. A mind keeps its identity, memories, beliefs and configuration when the underlying model provider changes.
|
||
|
||
## What Noema is not
|
||
|
||
Noema does **not** claim consciousness, sentience, self-awareness or personhood. It simulates *mechanisms associated with* cognition so that they can be studied and used. Behaviour that resembles emotion, curiosity, preference or identity is a property of the model being run and must not be read as evidence of subjective experience. See [docs/interpretation.md](docs/interpretation.md).
|
||
|
||
Noema is also not a chatbot with a memory bolted on. A user message does not go straight to an LLM. It becomes an observation, is perceived, triggers memory retrieval, competes in the workspace, is reasoned about, produces a response *intent* grounded in stored beliefs and uncertainty, and only then is turned into language.

Full description: [ARCHITECTURE.md](ARCHITECTURE.md). Decisions: [docs/adr](docs/adr). Plan and status: [PLAN.md](PLAN.md).
|
||
|
||
## Quick start
|
||
|
||
Requirements: Go 1.26+, Docker with Compose, `make`.
|
||
|
||
```sh
|
||
cp .env.example .env
|
||
# set NOEMA_MASTER_KEY (openssl rand -base64 32) and NOEMA_BOOTSTRAP_ADMIN_PASSWORD
|
||
make dev
|
||
```
|
||
|
||
This starts PostgreSQL (with pgvector) in a container, applies migrations, and runs `noemad` on http://127.0.0.1:8080. Log in with the bootstrap administrator, add an LLM provider under *LLM* and assign models to the `perceive` and `respond` roles, create a mind (or load the sample mind Dani with `noemactl mind import configs/minds/dani.json` after creating an API token under *Account*), and open its Conversation tab. Without a model the mind still answers, rendering its state directly.
|
||
|
||
## Configuration
|
||
|
||
Precedence: built-in defaults → JSON config file (`noemad -config path`) → environment variables (`NOEMA_*`) → runtime settings stored in the database and edited in the UI. Secrets come only from environment variables, secret files, or encrypted references; they are never included in exports or rendered back to HTML. See [docs/configuration.md](docs/configuration.md).
|
||
|
||
## Development
|
||
|
||
```sh
|
||
make tools # staticcheck, gosec, govulncheck
|
||
make test-race # unit tests
|
||
make test-db # tests that need PostgreSQL
|
||
make lint security
|
||
```
|
||
|
||
See [CONTRIBUTING.md](CONTRIBUTING.md) and [docs/ENVIRONMENT.md](docs/ENVIRONMENT.md).
|
||
|
||
## Security warning
|
||
|
||
Noema ingests untrusted data (documents, web pages, logs, repositories, model output) and can be granted capabilities that touch real systems. Read [SECURITY.md](SECURITY.md) and [THREAT_MODEL.md](THREAT_MODEL.md) before connecting it to anything you care about. Defaults are restrictive: every action capability starts as `ASK` or `DENY`, dreaming can never act, and shutdown is always under operator control.
|
||
|
||
## Cognitive concepts
|
||
|
||
| Concept | Meaning in Noema |
|
||
|---|---|
|
||
| Cognitive event | Immutable, typed record of anything that happened inside a mind, with provenance links |
|
||
| Epistemic kind | observation, fact, memory, claim, hypothesis, belief, prediction, assumption, inference, opinion. Never collapsed |
|
||
| Global workspace | Small, capacity-limited set of currently broadcast thoughts, selected by deterministic attention scoring |
|
||
| Working memory | Short-lived, decaying set of active items feeding every cognitive process |
|
||
| Memory systems | episodic, semantic, procedural, autobiographical; decay changes accessibility, never deletes |
|
||
| Belief | Proposition with confidence, status, evidence for/against, alternatives and version history |
|
||
| Prediction | Explicit expectation with window and criteria; resolution produces prediction-error events that recalibrate confidence |
|
||
| Drives and affect | Configurable scalar state that biases attention and style; inspectable and resettable |
|
||
| Self-model | What the mind can, cannot, and is currently doing; prevents false capability claims |
|
||
| Metacognition | Processes that audit the mind's own reasoning and emit warnings |
|
||
| Replay | Re-running a recorded cognitive sequence, labelled exact or approximate |
|
||
|
||
## CLI examples
|
||
|
||
```sh
|
||
noemactl status
|
||
noemactl mind list
|
||
noemactl mind create dani
|
||
noemactl ask dani "why was atlas slow yesterday?"
|
||
noemactl belief list --mind dani
|
||
noemactl event inspect <id>
|
||
noemactl replay <event-id>
|
||
noemactl provider test openai-main
|
||
noemactl approvals list
|
||
noemactl snapshot create dani
|
||
noemactl fork dani --snapshot <id> --name dani-test
|
||
```
|
||
|
||
## Status
|
||
|
||
Milestone M1 is complete: start, log in, create a mind, shape its personality, configure a model, chat, watch cognitive events live, inspect working memory, the workspace, memories, beliefs and provenance, restart, and continue the same mind. `go test ./tests/m1/` exercises that slice end to end. Phases 9–16 (goals, drives, predictions, metacognition, reflection, consolidation, relationship graph, capabilities, integrations, dreaming, snapshots, replay, experiments, hardening) are in progress; see [PLAN.md](PLAN.md) and [CHANGELOG.md](CHANGELOG.md). Screenshots will be added once the UI stabilises.
