timothyandClaude Opus 5 6fdf48de2d docs(849): drop a duplicated clause from the record, and record the sweep's yield ...

The `mechanics:` field ended with the same sentence twice — the enumeration of the
unreachable clauses was appended without removing the tail it replaced. Found by the
mutation-sweep agent while reading the record it was checking its own results against.

In its place, the number that makes the technique worth its cost: 60 mutants, 40 red, 20
survivors, on a tree that had already been through three per-finding review rounds by two
model families.
