mempalace.fact_checker

Source: mempalace/fact_checker.py

fact_checker.py — Verify text against known facts in the palace.

Checks AI responses, diary entries, and new content against the entity registry and knowledge graph for three classes of issue:

• similar_name — text mentions a name that's one/two edits away from another registered name, raising the possibility of a typo or mix-up.
• relationship_mismatch — text asserts a role between two entities (e.g. "Bob is Alice's brother") while the KG records a different current role for the same subject/object pair.
• stale_fact — text asserts a fact that the KG marks closed (valid_to in the past).

Purely offline. Inputs: entity_registry JSON + KG SQLite. No network.

Usage: from mempalace.fact_checker import check_text issues = check_text("Bob is Alice's brother", palace_path)

# CLI
python -m mempalace.fact_checker "Bob is Alice's brother" \
    --palace ~/.mempalace/palace

Functions

check_text

def check_text(text: str, palace_path: str = None, config = None) -> list

Return a list of issues detected in text.

Empty list means "no contradictions found" — absence of evidence, not evidence of absence. The detector is deliberately conservative: every issue is anchored to a specific KG fact or registry entry.
