Knowledge Engine bridges Obsidian wikis with Memvid

Strong idea, but only if you actually need both human curation and machine-speed retrieval; otherwise it risks duplicating the same knowledge in two places. The dual layer is sensible for teams that want readable markdown notes plus a fast programmatic retrieval path, and the content hashing plus drift detection are the right guardrails. The repo's scale guidance is believable: wiki-only is fine for small corpora, while the Memvid layer matters more once the document count grows and grep stops being enough. The main risk is operational complexity, since this replaces one simple wiki with a synchronized pipeline, so the payoff has to come from real retrieval needs rather than architecture aesthetics.
