Declare logical Evidence sources once and resolve exact retained inputs through
shared application workflows across 20 composition tools. Preserve domain-owned
authentication, source closure, caller choices, coverage and resource admission.

and fresh-import real-artifact workflows. Measurements, failed attempts and
coverage limits are recorded in docs/verification/evidence-input-composition-2026-10-31.md.
