When Skene indexes a repo, the output is a structured manifest: every analytics call with its library, event name, payload shape, file path, line number, and control-flow context. That manifest is the baseline. On the next PR, Skene rebuilds the manifest for the new state and diffs against the baseline.
How the baseline updates
When a PR with intentional changes merges, the baseline updates to reflect the new state. Changes you accepted are now the truth; future PRs only flag drift from there.
