Which campaigns are measurable, and where the untracked clicks went

Tracking hygiene, per campaign. GET /client/v1/constraints reports one match_rate for the account — enough to know a problem exists, not enough to fix it. This takes that number apart: a verdict per campaign, plus the ad clicks that reached no campaign at all, bucketed by cause.

Causes call for different repairs, which is why they are separated rather than summed: no_utm (the ad has no URL tags), unexpanded_macro (the tag holds a literal the platform never substituted), and unknown_campaign (the UTM names something outside the synced rows — a deleted campaign, a hand-written UTM, or a different ad account).

Uses the same window, grain and join as the analysis, so the two agree by construction. No conversion, lead or benchmark inputs — nothing here depends on them. Unlike the analysis, there is no volume floor: a small campaign with broken tags is precisely what this should surface.

Meta only for now.
