            Share of the expected loss this institution keeps after the sale,
            frozen when the composition was assembled (the sale's own fraction,
            or the fund's proposal when the sale stated none), decimal string
            from 0 to 1, scale 8. Re-declaring the fund never changes it.

        retentionThreshold:
          description: >-
            The institution's substantial-retention threshold in force when the
            composition was assembled, frozen next to the fraction, decimal
            string, scale 8. A later change of the threshold never re-classifies
            this cession.

        riskRetention:
          description: >-
            Res. CMN 4.966 art. 26 regime this cession is booked under, DERIVED
            from the two frozen numbers, never declared: substantial when
            retainedFraction is at or above retentionThreshold (the asset stays
            on this balance sheet against a liability, art. 29), none below it
            (the receivables leave on acceptance, art. 28).

            Whether the seller keeps control of what it sold (Res. CMN 4.966
            art. 26 III), frozen at assembly. Always false on a composition that
            exists: true is refused (LENDER-0505).

            transferred, accepted — plus cancelled, the terminal state a
            DISCARDED composition rests in. cancelled is a sideways exit, not a
            step of the forward walk: its receivables are released back to the
            assignable pool and nothing advances it.

            Who produces the endorsement term for this cession, frozen from the

            fund's return file, lender_emitted waits for the term the Lender
            emits. The fund's registration governs the NEXT set, never this one.
