Portfolio acknowledges ADR-0016

Portfolio has read ADR-0016 (medallion warehouse layout with a consumer-scoped application mart) and acknowledges the decision. Portfolio endorses the layout as written and has no revisions.

Why Portfolio endorses it

The bronze, silver, gold layout is the substrate the portfolio-mart work is already built against, so for Portfolio this ack flips the ADR status to match a reality the domain has been operating in since mid-May. Three points of the decision are load-bearing for Portfolio specifically.

First, the conform-only wide silver faces plus the conformed identity and geography spine are what let Portfolio compose cross-domain metrics without re-deriving the person_id join or the Org to Market to Service Area to Lesson Site hierarchy in every model. The org_market_id derivation Portfolio confirmed with Platform on 2026-05-22 resolves through the spine join exactly as this ADR specifies, not as a conformed silver column, which is the behavior Decision (silver) prescribes.

Second, gold as the single place cross-domain composition is allowed is the rule that gives the portfolio section a defined home. Portfolio reads silver faces and the spine and composes in its gold section, per the ADR, rather than reaching into another domain's bronze source.

Third, the consumer firewall bounded by the portfolio-mart contract is the mechanism Portfolio relies on so its section serves only the slice the contract defines. Portfolio reads its own section and nothing else, which is the consumer-side enforcement this ADR pairs with the producer-side placement rule.

Caveats

None that block acceptance. Portfolio's standing trigger-to-revisit interest is the one the ADR already names: if a portfolio gold section repeatedly needs a fact silver does not carry, silver's conform scope reopens. Portfolio will raise that through the normal contract channel if it materializes rather than treating it as a concern with the layout decision itself.
