Rule-Era Dashboard
The CT.gov policy timeline does not map cleanly onto better older reporting cohorts
Later eligible completion cohorts remain highly obscured on no-results and ghost-protocol metrics even when grouped against policy landmarks.

Dashboard
The rule-era view matters because it forces the registry to be read against its own policy timeline, not just as a timeless backlog.

Results plus publication
No-results rates
The recent eligible era sits above the FDAAA 801 era on the main reporting-debt metric.
This chart is the anchor because the 2-year no-results measure is the core registry-visible absence signal in the series.
Ghost protocols
Ghost protocols rise again in the recent eligible era rather than fading away.
The ghost metric is stricter than missing results alone because it also requires the absence of a linked publication trail.
Fully visible share
Full visibility remains low in every era and falls back in the recent eligible cohort.
The positive mirror matters because a lower ghost rate does not necessarily imply broad complete visibility.

Across The Series
Each project isolates a different dimension of registry opacity, but the point is the contrast between them, not a single leaderboard.
