feat: implement global workspace, working memory and the cognitive cycle
Phase 4 (ADR-0001). internal/attention scores thought candidates as a normalised weighted sum over ten named features with a per-term breakdown, ranked by (score, id) so ordering is total and replayable. internal/workspace holds the capacity-limited workspace (refresh by subject, decayed competition, explained admit/reject outcomes) and the decaying working memory. internal/brain runs one runtime per active mind: debounced wake-ups from the event bus (own output never re-triggers), a settle window so concurrently committing events are not skipped, bounded concurrent Observe calls with per-process isolation and timeouts, deterministic scoring, a loop detector that suppresses recurring thoughts and raises a metacognition warning, executive dispatch by thought kind, and one transaction per cycle whose events are published only after commit. Every candidate, selection, attention shift and broadcast is an event with provenance back to the triggering observation. Operators can run a cycle, pause, resume, reset transient state and change attention weights live; the manager reconciles runtimes with mind status. cognition/attend is the first process: deterministic candidates from external events using an urgency lexicon, novelty against context and trust-based operator priority.

### Added
|
||||
- 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`.

### Phase 4 – Working memory, global workspace, attention
|
||||
- ☐ `internal/brain`: `BrainState`, `Process` interface, registry, cycle loop, bounded pool, per-mind runtime lifecycle, modes, cursor advance, loop detector
|
||||
- ☐ `internal/attention`: feature extraction, weights, deterministic scorer, admission
|
||||
- ☐ `internal/workspace`: capacity-limited workspace + working memory with decay, persistence in `workspace_states`
|
||||
- ☐ `migrations/0004_workspace`
|
||||
- ☐ UI: workspace page (contents, candidates, scores, why won/lost), working memory panel
|
||||
- ☐ Tests: determinism, capacity, decay, cancellation, pool bounds, loop detection, restart continuity

||||
### Phase 4 – Working memory, global workspace, attention ☑
|
||||
- ☑ `internal/attention`: ten named features, per-mind weights, normalised weighted sum with per-term breakdown, total ordering by (score, id)
|
||||
- ☑ `internal/workspace`: capacity-limited workspace with refresh-by-subject, decayed competition, explained outcomes; working memory with activation decay and least-active eviction; token overlap for context relevance
|
||||
- ☑ `internal/brain`: `Process` interface and registry, per-mind runtime with debounced wake-ups, idle timer, settle window, cursor advance only on read events, bounded concurrent Observe with isolation and timeouts, deterministic scoring, loop detector with metacognition warning, executive dispatch by thought kind, single transaction per cycle with publish after commit, persisted snapshot, operator commands (cycle, pause, resume, reset, reload), cycle rate budget; manager reconciling active minds and waking on bus events (own output never re-triggers)
|
||||
- ☑ `internal/cognition/attend`: deterministic attention candidates from external events (urgency lexicon, novelty vs context, trust-based operator priority)
|
||||
- ☑ `migrations/0004_workspace`
|
||||
- ☑ API: workspace view, cycle now, mode, reset; config changes reload runtimes
|
||||
- ☑ UI: workspace page (contents with score breakdown bars, working memory, last cycle candidates with fate and reason, controls, attention weight editor) refreshing live on broadcasts
|
||||
- ☑ `noemactl workspace show|cycle|pause|resume|reset`
|
||||
- ☑ Tests: scoring determinism and bounds, ranking order, admission/refresh/capacity/decay/prune, provenance chain across a cycle, restart continuity, no self-triggered cycles, loop suppression, pause/reset/cancellation
|
||||
|
||||
### Phase 5 – Episodic and semantic memory
|
||||
- ☐ `migrations/0005_memory`: memories (kinds, tsvector), memory_relationships, memory_embeddings (conditional pgvector)
