How does Renovate work at a high level — what is its execution flow?

Renovate follows a repeatable discover-evaluate-act cycle each time it runs.

Renovate execution flow
Step	What happens
1. Discover repos	Connects to platform API and lists accessible repositories
2. Clone and scan	Each repo is cloned; dependency files are detected
3. Extract dependencies	Files are parsed by the relevant manager to extract current versions
4. Look up updates	Registries (npm, PyPI, Docker Hub) are queried for newer versions
5. Filter and apply config	Schedules, ranges, and ignore rules filter which updates to action
6. Create/update PRs	Branches and PRs are raised for each actionable update
7. Automerge (optional)	If enabled and CI passes, Renovate merges the PR automatically

Renovate is stateless between runs — it re-discovers everything from scratch each time. The only persistent state is the PRs and branches on the platform. Rerunning Renovate is always safe and idempotent.
