Running `v1.0.25`.

# Changelog

## v1.0.25 - 2026-05-09

- Added an admin-only service provider selector for the public Codex Responses gateway so new starts/resumes can stay on GPT-5.5 Codex or route through DeepSeek v4 Pro via OpenRouter.
- Added a Responses-compatible OpenRouter adapter for `deepseek/deepseek-v4-pro` while keeping the client-facing model hidden behind the existing ChatPlus GPT-5.5 provider config.
- Added an admin model usage chart with provider/model request totals, token totals, and wallet deductions.
- Updated token wallet billing to $5 per million input tokens and $30 per million output tokens for both providers.

## v1.0.24 - 2026-05-08

- Updated the ChatPlus public Codex compatibility target to Codex CLI `0.129.0` and verified the host is already running `@openai/codex` `0.129.0` with current npm.
- Enabled Codex app-server `experimentalApi` negotiation so `permissions` profile payloads used by the new `/permissions` Full Access client toggle are accepted.

## v1.0.21 - 2026-05-03

- Hardened Stripe wallet top-ups so paid Checkout sessions are reloaded from Stripe, fulfilled idempotently, and credited as soon as the webhook or return confirmation succeeds.
- Preserved existing wallet API tokens during Stripe top-ups, low-balance SSO, and normal admin simulation so G2G buyers do not need to reconfigure Codex after adding credit.
- Added direct client simulation controls to the admin Access & Tokens page.

## v1.0.20 - 2026-05-03

- Repaired legacy G2G wallet-token state so each buyer account has exactly one active buyer API token.
- Hid expired/admin-impersonation tokens from buyer token summaries to avoid confusing G2G delivery credentials.
- Hardened dashboard login token reuse so existing active wallet tokens are preferred over creating extra buyer tokens.
- Kept the G2G creation success message visible after dashboard refresh so admins can see that the order was created.

## v1.0.19 - 2026-05-03

- Fixed G2G order creation so the admin page gives visible progress and creates a usable account from a single wallet-credit amount.
- Stopped customer dashboard logins from issuing a new wallet API token every time; existing active wallet tokens are now reused.
- Expanded the G2G delivery and token display areas so admins can read and copy the generated setup text without cramped fields.

## v1.0.18 - 2026-05-03

- Added a once-per-version release notes modal for admin and customer dashboard sessions.
- Preserved direct admin section links after login and made Access & Tokens load independently of the full dashboard refresh.
- Added wallet balances to the Access & Tokens API key list so admins can see remaining credit beside each token.

## v1.0.17 - 2026-05-02

- Corrected public Codex token billing so cumulative reported input context is stored separately and only newly added input tokens are charged.
- Added token usage idempotency by response ID to prevent duplicate wallet deductions for the same completion.

## v1.0.16 - 2026-05-01

## v1.0.15 - 2026-05-01

- Added plaintext token persistence for newly created managed API keys so admins can retrieve customer and G2G tokens after creation.
- Updated the admin Access & Tokens and Customers & Wallets tables to show full stored tokens with copy controls instead of only prefixes.
- Labeled legacy hash-only token rows clearly because older plaintext tokens cannot be reconstructed from their hashes.

- Fixed the G2G Orders admin layout so the create form and delivery preview use the intended 5/7 grid split instead of collapsed single-column cards.

## v1.0.6 - 2026-04-29

- Updated the public Codex startup commands shown on the client dashboard and install page.

- Corrected the official OpenAI `@openai/codex` CLI setup guide for ChatPlus provider usage.
- Added generated command variants that isolate ChatPlus with `CODEX_HOME="$HOME/.chatplus-codex"` so existing OpenAI/ChatGPT Codex logins are overridden for that run.
