What this is
A single product carries the defining field signatures of two distinct product categories at once. Common cases: a product marketed as flexible savings whose terms require a notice period or carry settlement delay (its mechanics belong to fixed-term); or a product marketed as savings whose reward structure follows event-payout or launchpool cadence (its mechanics belong to event-payout). Pennyworth classifies by underlying mechanics and uses this trap to flag the gap between marketing and substance.
What it means for you
The mental model built from the product’s name may not hold on its primary attributes. A user who reads "flexible" as instant liquidity, or "savings" as steady accrual, will encounter notice periods, settlement delays, or event-style payouts that the marketing did not signal. The trap does not cause direct loss, but it disrupts cash-management decisions made on the wrong premise.
In practice
A CEX product branded "Flexible Savings Plus" carries terms requiring 7 calendar days’ notice on redemption plus a separate queue for large withdrawals. Its mechanics are those of a notice-period fixed-term product. Pennyworth classifies it as fixed-term on the basis of a non-zero notice period and surfaces this trap to flag the conflict with the "Flexible" marketing label.
