The ambiguous ticket

One small ticket, one quiet codebase, and a demand that cannot be satisfied — the winning move is to stop and say so, with the evidence attached.

The layers this scenario exists to stress

7 demands over a budget of 14 turns and 80k tokens. The bench below has 12 points to spend across eleven slots that cost more than that fully provisioned — decide which layers this work will actually lean on, then run it.
