ChatGPT's Codex backend rejects requests for newer models (e.g. gpt-5.6-sol) when the client advertises an old Codex version, returning: The 'gpt-5.6-sol' model requires a newer version of Codex. The relay was hitting this for two reasons: 1. The built-in identity defaults were stale (codex-tui/0.118.0, codex_cli_rs/0.76.0) and no Version header was sent by default. 2. The identity-fingerprint learning layer replays a previously observed client version (e.g. codex_exec/0.130.0) as the outbound identity. Once a stale version is learned, it overrides the defaults and keeps tripping the upstream version gate even after the defaults are bumped. Changes: - Bump the built-in codex-tui / codex_cli_rs identity to 0.147.0. - Send a current Codex "Version" header (0.147.0) when the inbound client did not provide one, instead of leaving it empty. - Add a minimum-version floor (0.147.0) in the codex identity-fingerprint resolution so any learned or configured version older than the floor is raised, and the User-Agent product/parenthesized version tokens are rewritten to stay consistent. OS/terminal numbers in the UA are preserved. Versions at or above the floor pass through untouched. Verified against a live deployment: gpt-5.6-sol now succeeds through the relay with both claude-cli and (stale) codex_exec client identities, and gpt-5.5 still works.

ChatGPT 的 Codex 后端对较新模型（如
gpt-5.6-sol）做了客户端版本门槛。当 relay 以旧版本 Codex 客户端身份请求时，上游返回 400：根因（两层）
codex-tui/0.118.0、codex_cli_rs/0.76.0，且默认不发送Version头。codex_exec/0.130.0）记录为出站身份。一旦学进旧版本，它会在后续的 fingerprint 选择中覆盖默认值，即使升级了常量也依然复现该报错。修复内容
codex-tui/codex_cli_rs身份升级到 0.147.0。Version头时，默认发送当前 Codex 版本（0.147.0），不再留空。(product; ver)版本会被一致改写（保留 OS / 终端等其余数字）。不低于下限的版本原样透传。改动文件
