Self-Curating Wiki (CONCEPT:KG-2.19)

Overview

The Self-Curating Wiki continuously ingests a markdown knowledge vault into the graph but only when pages change — each file's SHA-256 is tracked so unchanged pages are skipped, and state is written crash-safely. Assimilated from memory-os (scripts/wiki_continuous_ingest.py). Extends KG-2.7 (Research Intelligence / Ingestion).

How it works

• Delta-skip ingest. WikiCurator.changed_files returns only new/modified pages (by content hash) vs the stored state; curate ingests just those via an injected ingest_fn and commits the new hash state. Re-running an unchanged vault ingests nothing.
• Reuses existing ingestion. curate_wiki routes changed pages through IngestionEngine.ingest (which already does concept/entity extraction, KG-2.8 delta hashing, and linking); the existing SynthesisEngine auto-curates promotions (episode→preference, decision→principle).
• Crash-safe state. State is written via tempfile → fsync → atomic os.replace, so a crash mid-write never corrupts the ingest ledger.
