Struct PromptFactsCache 

pub struct PromptFactsCache {
    pub triples: Vec<(String, String, String)>,
    pub formatted: String,
}

Cached prompt-facts surface: raw triples and a pre-formatted Markdown block.

Why: The get_prompt_context tool serves two access modes — unfiltered (returns the pre-formatted block directly) and filtered (re-runs the formatter on a query-matching subset). Caching only the formatted string would force a fresh gather_hot_triples pass for every filtered call; caching only the triples would force re-formatting for every unfiltered call. Holding both lets the hot path stay O(1) and the filtered path stay O(n) without ever re-walking the KG. What: A plain Default + Clone struct. triples holds the active (subject, predicate, object) rows for every hot predicate across every palace; formatted is build_prompt_context(&triples) cached for the no-filter case. Test: rebuild_prompt_cache_populates_triples_and_formatted (in tools::tests); get_prompt_context_filters_by_query.

Fields

triples: Vec<(String, String, String)>

All active hot-predicate triples: (subject, predicate, object).

formatted: String

Pre-formatted string of all triples (used when no query filter).
