Deterministic execution level structural context for next-auth

[Arc-a-it]

Goals

1.Provide a machine-derived, execution-level view of how next-auth actually coordinates internally

2,Surface hidden coordination hubs and blast-radius risks

3, Improve onboarding, architectural review, and AI-assisted reasoning about the codebase

Non-Goals

1 ,Not a feature request for next-auth

2 , Not documentation replacement

3 ,Not proposing changes to runtime behavior

Background

Large authentication systems accumulate implicit structure that is difficult to infer by reading files in isolation.

While next-auth appears modular, analysis shows strong coordination through adapter layers and example utilities that have broader impact than expected.

Current alternatives rely on human explanations or ad-hoc diagrams, which are non-deterministic and incomplete.

This context was generated directly from source code to reflect execution and dependency reality.

Proposal

This is not a proposal for next-auth itself, but a share of an external analysis artifact generated from the repository.

It highlights coordination hubs (e.g. packages/utils/adapter.ts with a 41-file blast radius), multi-framework adapter coupling, and structural layers across runtime code, adapters, and examples.

No changes proposed.
No action required.
