The active breadcrumb identifies the final actual drilldown step · case 01
The active breadcrumb identifies the final actual drilldown step is violated by the widget projection.
ROOT CAUSE
The active-crumb decision uses `len(d['trail'])` instead of the stipulated drilldown-trail projection.
VERIFIED REPAIR
Implement the declared active-crumb projection: `len(d['trail'])-1 if d['trail'] else None`.
Unsuccessful approach: The attempted correction `0 if d['trail'] else None` still violates the explicit contract fixtures.
Case contract
A facet drilldown trail records a sequence of scoped constraints; returning to a breadcrumb truncates later drilldowns while preserving independent global filters. This example checks: The active breadcrumb identifies the final actual drilldown step.
Why this case matters
Filter-widget state and serialization must preserve user constraints while the view changes.

Verification & scope
Deterministic bounded UI-state model only; no browser, query engine, network, or production-standard conformance is claimed. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
