Attempts

Each one is a hypothesis about the eight-step review, the set it was tested against, and what it did to the queue. 4 of 6 reached a verdict; 2 are still open.

Drafted1

A hypothesis with a set to test it against. Nothing spent yet.

Grading1

Running. No verdict until every run is in.

Inconclusive3

Graded, but the interval overlaps. The change may have worked; the evidence cannot say.

Kept1

Separated above baseline and promoted.

Discarded0

Separated below, and reverted. These rows are the most useful in the ledger.

None

Two of the six reached a verdict. That is the normal shape of this work — an attempt that comes back inconclusive has still told you the change was not worth the runs, and the discarded column is where the most transferable lessons sit.
