The workcell may have adequate capacity over the full closing period yet become fragile during this synchronized arrival: several cassettes occupy the handoff surface, staff reach for the same counter, and material from different tills can be placed within the same working area. The resulting physical overlap can cause cassette-order ambiguity, mixed cash batches, interrupted counts, recounts, or weakened chain-of-custody evidence.","actors":["Sealed, uniquely marked till cassettes","Cashiers or secure-courier staff delivering cassettes","Cash-office reconciler","Currency counter and reconciliation work surface","Secure cash-office partition and pass-through","Mechanical buffer rack, escapement, and completed-cassette cradle"],"observable_state":"Observable indications are a narrow arrival window after shift close, multiple unopened or partly processed cassettes simultaneously present at the counting surface, more than one cassette accessible through the handoff, cross-cassette material proximity, recounts or identity exceptions concentrated in that window, and average-period throughput that remains within the workcell's capacity.","consequence":"Synchronized physical access can degrade batch identity and custody continuity even when total closing-period workload is serviceable, impairing timely and supportable cash-to-ledger reconciliation.","affected_objective":"Preserve one-to-one association between each till cassette, its physical contents, and its reconciliation record while completing end-of-shift cash control without a release-time pileup.","intervention":"Install a secure gravity buffer as the sole normal physical pass-through into the counting enclosure. Incoming sealed cassettes enter bounded, individually separated lanes. A mechanical escapement exposes exactly one cassette in the pickup bay while blocking every following cassette. After the reconciler closes the current cassette and places it in a locked output cradle, the cassette's weight moves a linkage that clears the pickup bay and releases the next cassette. A rotating mechanical selector alternates occupied lanes to avoid repeatedly favoring one lane. The enclosure prevents reaching around the gate, and an externally accessible keyed release permits removal after a jam or emergency without opening cash batches. No software determines admission or cassette order.","structural_mapping":[{"archetype_element":"Shared Release Signal","domain_realization":"The common end-of-shift closing time causes many tills to release their sealed cash cassettes toward the cash office together."},{"archetype_element":"Waiting Population Boundary","domain_realization":"The enclosed rack physically bounds the set of delivered but not yet admitted cassettes and keeps each cassette in a separate lane."},{"archetype_element":"Finite Choke Point","domain_realization":"One secure currency-counting and reconciliation workcell can maintain controlled custody for only one till batch at a time."},{"archetype_element":"Release Correlation","domain_realization":"Correlation appears as many cassette arrivals and attempts to access the workcell within the same short closing-time window."},{"archetype_element":"Dispersion Policy","domain_realization":"The escapement converts the clustered arrivals into successive physical admissions."},{"archetype_element":"Admission Gate","domain_realization":"A mechanical interlock makes only one cassette reachable from inside the counting enclosure."},{"archetype_element":"Capacity Recovery Signal","domain_realization":"Weight in the completed-cassette cradle mechanically indicates that the prior cassette has left the active work position and permits the next release."},{"archetype_element":"Fairness and Starvation Guard","domain_realization":"A ratcheting lane selector rotates admission among occupied lanes, and lane capacity supplies a visible upper bound on waiting population."},{"archetype_element":"Priority Escape Lane","domain_realization":"A controlled keyed extraction path permits emergency or jam recovery without defeating the normal one-cassette aperture."}],"mechanism_mapping":[{"mechanism_slug":"semaphore_limited_release","role":"The pickup bay is a one-permit physical semaphore: occupancy blocks the linkage, and transfer to the completed cradle restores the permit.
