Why: I3 adds the reader/evidence-panel module whose contract types
(documentCockpit.ts) are consumed by tests and the I4 combination work; the
repo's knip ratchet exists for exactly this deliberate, documented raise.
Code paths themselves reduced first (attempted de-export churned unrelated
surface, reverted in favor of the baseline bump).
Evidence: knip 51 <= 51 via scripts/check-knip.mjs; vitest 324/324; tsc and
vite build green.
Impact: baseline file only.
