Modifications from upstream

Codex Switch is a modified derivative of Frank Song/dsh-codex-connect, which itself includes software derived from 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 and LICENSE.

Codex Switch changes

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

• a new package and plugin identity, dsh-codex-switch;

• 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.
