# Modifications from upstream

Codex Switch is a modified derivative of
[Frank Song/dsh-codex-connect](https://github.com/franksong2702/dsh-codex-connect),
which itself includes software derived from
[Yan-Zero/dsh-codex](https://github.com/Yan-Zero/dsh-codex).

The Codex Switch work began from the Codex Connect
`v0.1.0-alpha.4.5` release. Copyright and attribution for both upstream
projects are retained in [NOTICE](NOTICE) and [LICENSE](LICENSE).

## Codex Switch changes

Copyright 2026 CHAKEW. The derivative work includes, among other changes:

- a new package and plugin identity, `dsh-codex-switch`;
- a native repository for multiple independent ChatGPT OAuth accounts;
- Manual and Automatic account selection, per-account participation, ordering,
  usage display, renewal, sign-out, backup migration, and rollback;
- an exclusive-owner migration path from `dsh-codex-connect`;
- revised Web settings and account-management interfaces;
- provider-backed banked reset discovery and redemption in Web, plus banked reset inventory in the account-usage CLI;
- quota-window lifecycle classification that keeps capacity separate from stable reset anchors;
- explicit, confirmed, account-scoped quota warmup across authorized Codex model pools;
- additional route, filesystem, OAuth, image-fetch, and diagnostic hardening;
- expanded integration, security, migration, UI, and packaging tests;
- pinned-source reset-lifecycle research and implementation notes; and
- updated English and Chinese user documentation and release validation.

Files changed from the upstream release are identifiable through this
