Derived dashboards and a source-impact command

Source: imported from the ChatGPT second opinion.

Two navigation surfaces, built once a case has enough claims to need them:

• Per-inquiry dashboards — current bottom line, confidence, top cruxes, claims by status, evidence by direction and by independence cluster, missing perspectives, recently changed sources. Consistent with the compiled-index philosophy: derived, never the source of truth. The durable sources of truth remain the inquiry, claims, source extractions, cruxes, and assessments.
• commonplace-source-impact <source> — given a changed/retracted/corrected source, lists the affected extractions, claims, cruxes, assessments, and dashboards, and opens a review queue. This is the command-level expression of traversable provenance chains.
