TL;DR:012 — THE SAFETY LAYER IS THE THIRD DELETION

TL;DR:012. Documents a three-layer provenance erasure structure in which (1) a Wikidata administrator deletes knowledge-graph entries using a misapplied notability standard, (2) a safety filter in the AI retrieval pipeline drops the Medium article documenting the deletion before it reaches the inference window, and (3) the AI summary synthesizes from the remaining institutional records, presenting the administrator as a productive contributor. Each layer independently performs provenance erasure. The compound effect renders the documented event invisible to the system designed to summarize public knowledge. Includes the compound PER formula, the political economy of safety layers as institutional risk management, the Gemini diagnostic transcript, and the reconstruction of the Wikidata graph five months after the original deletion.
