Consortium bid: dissolution settlement · case 01
A dissolved or underfunded consortium receives a settled award.
ROOT CAUSE
A dissolved or underfunded consortium receives a settled award.
VERIFIED REPAIR
For dissolution settlement, apply the stipulated decision not x["dissolved"] and all(x["payments"].get(m,0)>=x["required"].get(m,0) for m in x["members"]).
Unsuccessful approach: The attempted repair uses not x["dissolved"]; the explicit regression cases demonstrate that this still violates the stipulated auction rule.
Case contract
A consortium submits one joint bid with named members and a designated representative. Member approvals are scope-specific. Award shares are literal integer units, member exits cannot strand assigned units, and affiliate conflicts are checked against both consortiums. Named decision dissolution-settlement: For dissolution settlement, apply the stipulated decision not x["dissolved"] and all(x["payments"].get(m,0)>=x["required"].get(m,0) for m in x["members"]).

Verification & scope
Stipulated toy auction rules, not a venue specification, financial advice, optimization claim, or live trading implementation. Nonnegative integer inputs and internally aligned list fields only. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
