Search and Discovery

The read path a data consumer actually experiences, and where entitlements are applied.

Decisions

Entitlements are resolved before ranking, not after. Filtering results afterwards leaks existence through counts, facets and totals.
Certification and quality are ranking signals, not just badges. The trusted asset should win the search, not merely look better once found.
Popularity is logged asynchronously so telemetry can never slow or fail a search.

Targets

Search p95 under 300 ms at 5 million indexed assets.
Faceting on domain, platform, owner, classification, certification and quality band.
Read cache holds hot asset profiles for 15 minutes, which also covers a search-index outage (view 22).

Assumption

Visibility is attribute-based on domain plus sensitivity label. Asset-level access-control lists were rejected as unmanageable at this scale.
