Catalog tracking observation. This repository is measured with the same fixed window and ruleset, but it is not part of the published benchmark or its aggregate claims.

Provides a set of libraries which add service API versioning to ASP.NET Core Minimal APIs, Controllers, gRPC, OData, and Web API (Classic).

02Drivers

What shapes this result

Mode, timing, and detected signatures show whether the result reflects broad adoption or one concentrated workflow.

Assisted or autonomous

3assisted

1autonomous

Assisted — a developer’s identity authored the commit and the agent added itself as co-author. Autonomous — a bot identity authored the commit without a human identity attached.

Agent share by month

Peak month: 10.3%. Bars are scaled to that peak, not to 100%.

04Method

What entered the denominator

The result begins with commit history, removes merges and routine automation, and reports literal agent signatures as a lower bound.

Exclusion ledger

Commits in window	195
Merge commits removed	−0
CI / dependency bots removed	−4
Considered	191

Bots are excluded from the denominator entirely. Agent attribution requires a literal supported signature; no code-style inference is used.
