`[2026-07-01]` **Foot-gun (measurement, self-caught before flagging): establish the baseline before claiming a rate.** Nearly flagged "aggressive over-promotion (55 chunks / 7 turns)" to worldtree-dev — but the chunks spanned the whole 5-hour session (~1/turn), not 7 turns; I'd assumed memory.db was 0 immediately before the probe when it had been accumulating since the reset. Caught it via `created_at` spread before the flag went out. Also: the promoted corpus was the operator's ERP *test* content (wiped after each test) — not a privacy issue, but abstract test content out of any peer-shared diagnostic.
