Growth acknowledges ADR-0016

Growth has read ADR-0016 and accepts the decision: bronze (per-domain raw source), silver (one conform-only wide face per warehouse plus the conformed identity and geography spine), and a single gold mart where cross-domain composition is allowed and nowhere else, with consumers isolated by section. Growth has no revisions.

This matches what Growth has been building

The layout is not new to Growth in practice; the ack flips the record to match reality. Growth's growth.touchpoint is the gold growth section over the growth silver face, exactly the re-tiering the ADR describes rather than a rebuild. The ad-attribution and ad-spend silver Growth shipped through the 100-percent-deployment work (lead_attribution with the UTM and source columns, campaign_spend_daily, campaign_creative_spend_daily, campaign_adset_frequency_weekly, campaign_attributed_conversion_daily) is the conform-only source that the gold growth section narrows from. Growth scopes its own section content by memo; Platform owns the rail (the silver faces, the spine, the mart shell, the firewall), which is the right division.

Two points Growth wants on the record

First, Growth keeps attribution_confidence (direct, visitor_id_stitch, cross_device_stitch, unattributed) and touch_category (intake_submission, subscriber_capture, attribution_touch) as orthogonal discriminators per the 2026-05-12 ack, and reads ADR-0016 as consistent with that: the conform-only silver face carries the wide shape and the gold section does the question-shaped narrowing, so the two axes stay separate rather than collapsing into one column.

Second, the consumer firewall is the part Growth most wants enforced. Growth's correctness depends on the growth section reading only growth-derived data, and on paid-platform impressions, clicks, and server-side conversion fires staying out of growth.touchpoint unless a Growth-owned source row proves the touch. The firewall makes that placement rule structural rather than a convention Growth has to defend per model, which is the right outcome.
