Phase 6. Beliefs are propositions with a prior set by epistemic kind and a confidence computed from typed evidence: sigmoid(logit(prior) + slope × (support × diversity − opposition)), where support from a single source is discounted so repetition cannot manufacture certainty, and bounds keep the mind away from absolute certainty. Every evaluation stores its breakdown and appends a version row protected by the append-only trigger; the belief page shows the arithmetic, evidence for and against, alternatives, contradictions and history. Contradiction detection is deterministic first (negation plus token overlap): a hit emits contradiction_detected, links both beliefs and makes each counter-evidence for the other so both trend to contested. Operators can assert beliefs (their statement is the evidence), add evidence, mark a belief wrong (pinned rejected, history kept) and forbid an inference; do-not-infer corrections block matching hypotheses. Retracting a memory retracts the evidence that cited it and re-evaluates the beliefs concerned. The associate process proposes low-confidence causal hypotheses from co-occurring notable observations, and the hypothesis handler turns admitted ones into beliefs with automatic alternatives, closing demo scenarios 1 and 2 without any model call.

## [Unreleased]
|
|
|
|
### Added
|
|
- Phase 6 beliefs: evidence-derived confidence with inspectable arithmetic, statuses, alternatives, append-only history, deterministic contradiction detection, temporal-association hypotheses, operator corrections (wrong, do-not-infer, inaccurate memory), belief explorer and CLI.
|
|
- Phase 5 memory: episodic/semantic/procedural/autobiographical memory with epistemic status, fused retrieval with inspectable component scores, optional pgvector embeddings, decay without deletion, attention-gated encoding, retrieval process, memory explorer and CLI.
|
|
- Phase 4 cognition core: deterministic attention scoring with inspectable breakdowns, global workspace and working memory with decay, per-mind cognitive runtime with bounded concurrent processes, loop detection, operator controls, live workspace page and CLI.
|
|
- Phase 3 events: append-only cognitive event store with provenance links, filtered queries, durable cursors, live SSE streams with resume, forensic event explorer UI, thought stream page, operator observations and CLI.
|
|
- Phase 2 minds: structured personalities with append-only version history, diff, restore, templates with preserved overrides, self-model, mind lifecycle (create, clone, disable, archive), API, UI editor and CLI.
|
|
- Phase 1 foundation: configuration, structured logging, metrics, migrations, local authentication (Argon2id, sessions, CSRF, lockout, roles, API tokens), audit log, JSON API skeleton, server-rendered admin UI with light/dark theme, `noemad` and `noemactl`.
|
|
- Repository foundation: plan, architecture, security model, threat model, ADRs, Makefile, container files.
