What the numbers mean
- Sessions counted
- Top-level sessions, including their subagent work. Support and guardian sessions are left out. The total also includes sessions that used no listed spell.
- Spell usage
- A spell counts once per root session when one of its log matches appears. Repeated calls do not add sessions. Missing matches or unsupported log formats can undercount.
- Sessions per month
- The root session's start month in UTC. Sessions without a known start time are left out of monthly counts.
- Harness split
- The harness of the root session, even when a child did the work.
- Seen together, in this order
- Every combo step appeared in the same root session. Order compares first-use times; equal times count as ordered.
- Test recoveries
- A failed test followed by a passing test from the same runner family in the same member session. This is an association, not proof that a spell fixed the test.
- Often used with
- Other listed spells recorded in the same root sessions.
