Groom td-4a09f7 with JTBD problem statement and execution options

Why this matters: td-4a09f7 is a top-priority referral item but currently lacks a precise problem statement and decision-ready option framing, which increases sequencing risk for Glenn's team.\n\nScope: Define the core job to be done, evaluate 2-3 focus options with evidence from existing analyses, and recommend the next execution sequence with owners and success metrics.\n\nSource signal: td-4a09f7 description is broad ('determine focus') and does not specify JTBD/problem severity/success criteria.
