Erasure-Completeness Certificate

GDPR Art. 17 erasure request — support-conversations subject; Art. 17 vs Art. 18 tension on retention-pinned fine-tune corpus.

◆ Substrate gap — P7 verifier pending

P7 erasure-completeness verifier pending — substrate gap. Render shows what a future certificate WILL look like.

P7 implementation pending. The substrate primitive is a reverse-direction T6 information-flow walker over the workspace tag graph; the kernel currently exposes T6 in forward mode only (silver-l8 / l12 protocols). Closing this gap is its own workstream — see references.

trigger: First customer pilot requires a real erasure-completeness certificate (D7 in product surface §3) OR a Phase-P substrate workstream lands the reverse-T6 walker. Whichever fires first.
