@zed-industries/codex-acp is archived; its last release (0.16.0) bundles an
older Codex core that doesn't know newer models, so a config.toml model such as
gpt-6.1-sol fell back to generic metadata with a warning. The maintained adapter,
@agentclientprotocol/codex-acp, runs the Codex App Server from a current
@openai/codex and lists the account's models.
