🌙 Feature Spotlight: Generative Dreaming & Offline Sleep Consolidation

We are excited to spotlight one of Spector's most profound neurocomputational features: Generative Dreaming and Offline Sleep Consolidation.

💤 Why Do Artificial Minds Need to Dream?

In biological systems, episodic memories encoded during waking hours undergo Active Systems Consolidation during slow-wave and REM sleep. As proposed by neuroscientist Erik Hoel in The Overfitted Brain Hypothesis, dreaming injects structured stochastic noise into memory representations to prevent overfitting to idiosyncratic daily interactions.

Traditional static vector databases suffer from "memory overfitting"—retrieving literal conversational quotes rather than generalized semantic wisdom.

🔬 How Spector Implements Generative Dreaming

Spector introduces a dedicated offline sleep consolidation engine implementing the dream, simulate, and commit_simulation recall algebra operators:

1. Sharp-Wave Ripple (SWR) Replay

During idle or scheduled sleep phases, Spector triggers high-frequency replay sweeps across recent episodic logs, identifying clusters of high emotional valence, unresolved tasks (Zeigarnik open loops), and high prediction error (novelty z-scores).

2. Holonomic Stochastic Recombination

Replayed memory traces are passed through a 12-stage generative recombination pipeline that explores anti-centroid associative links and counterfactual scenarios ("What if the user had rejected the proposed migration?").

3. Cognitive Source Monitoring & Provenance (NF7)

To prevent confabulation and memory hallucination:

• Offline dreaming emits traces tagged exclusively as source = simulated.
• Default recall operations hard-gate and omit simulated traces (allow_simulated = false).
• Only through explicit commit_simulation can verified hypotheses be promoted to distilled semantic facts, maintaining an unbroken provenance DAG to the source episodes.

4. Memory Compaction & Hebbian Potentiation

Dreaming sweeps strengthen associative graph edges (Hebbian co-activation) and execute non-destructive storage strength updates ($S$) across the memory web.

🛠️ API & MCP Integration

Inspect or trigger dreaming through Spector's MCP interface:

• simulate: Execute an online counterfactual probe without mutating state.
• introspect: Inspect offline dream schedules, tier populations, and source counts.
