This brief is the INSIDE (credentialed account + DLA/AUA-fenced data). Do not re-catalog the public proxies.\n\n**Why.** Duplicating the register weakens the seam and the editorial discipline. The point of separating them is that the *same underlying sold/historical data now appears on both sides* — that tension IS the article. Re-cataloging buries it.\n\n**How to apply.** Reference the register; do not restate it. When the article wants to gesture at the public layer (e.g., \"the headline price is on HouseSigma; the relisting-chain pattern is not\"), point at the register rather than reproducing it.
