CodexSwitch v26.10.05.0943

Removed

• Removed all Claude Code support: the Clients pane, the claude launcher and
  settings merge, the Claude Messages proxy routes (/claude/...), the Python
  and Go Claude translators and the codexswitch-claude-token helper.
  CodexSwitch works with the Codex CLI only again.
• Removed the Microsoft Foundry provider, which only existed to serve Claude
  Code. Use the Azure provider instead. A Foundry entry that was saved in the
  credential vault is left untouched.
• codexswitch use and codexswitch run no longer take a codex|claude
  client argument: use codexswitch use PROVIDER MODEL [REASONING] and
  codexswitch run [ARGS...]. The obsolete client key is dropped from the
  switch state on the next activation.

Fixed

• Malformed, oversized or unrelated proxy health responses now report unhealthy
  instead of crashing status and activation.
• The Go proxy rejects null, multiple and trailing JSON request bodies and
  returns HTTP 413 for oversized requests.
• Forwarded SSE responses flush incrementally; truncated upstream responses
  abort the downstream connection. Retry-After and request IDs are preserved.

Changed

• Added GPT-6 Sol and GPT-5.6 Terra to the native OpenAI fallback model list,
  keeping both selectable when Codex cannot refresh its live catalog.
• Read the native Codex model catalog from the active Codex home so account-
  available models such as GPT-6 Sol appear in Commander.
• Upgraded Textual to the 8.2 series and cryptography to the 50.0 series,
  verified with the backend, vault and headless Commander test suite.
