Interpose reads the same custody evidence as Countervail, but interprets it as underwriting information: how volatile the defense cost may be, what facts are missing, what conditions would reduce exposure, and whether the account is eligible.
The trigger is not an AI malfunction. The exposure exists when normal, correct system operation creates records that later have to be preserved, reviewed, and produced in response to a subpoena, regulator, investigation, or litigation hold.
Use Interpose after a Countervail scan, vendor review, or manual intake has identified the AI record custody surface. The workbench turns that surface into eligibility, conditions, referrals, and missing-fact requests.
Return to incomplete submissions, compare open accounts, and identify which accounts need referral, missing facts, or drift review.
A single account may be manageable. A portfolio with repeated unknown retention, weak deletion posture, or vendor concentration may not be.
Every submission walks the Interpose Custody Underwriting Assessment: substrate scan, exposure classification, trigger alignment, condition structuring, fact verification, decision, and human sign-off. The stage strip sits across the top of the workbench and moves as the submission progresses.
