Struct RootIndex 

pub struct RootIndex {
    pub version: u64,
    pub updated_at: DateTime<Utc>,
    pub active_context: Vec<RootEntry>,
    pub recent_patterns: Vec<String>,
    pub historical_summary: Vec<HistoricalPeriod>,
    pub topics: Vec<TopicEntry>,
}

ROOT index — the “table of contents” for all agent knowledge.

Agents use this to understand what they know at a glance (O(1) lookup). Dream automatically rebuilds this on every run.

Fields

version: u64

Index version (incremented on each dream).

updated_at: DateTime<Utc>

Last update timestamp.

active_context: Vec<RootEntry>

Active context entries (recent ~7 days).

recent_patterns: Vec<String>

Recent patterns observed across sessions.

historical_summary: Vec<HistoricalPeriod>

Historical summary (monthly breakdowns).

topics: Vec<TopicEntry>

Topic index — all known topics with type and freshness.

Implementations
