Stage Chat Codex 0.2.1

Install the Codex connector and its Stage Chat dependency through public Packagist packages. The operational examples use generic service paths, and the repository welcomes focused contributions from people and agents.

composer require skyyware/stage-chat-codex:^0.2.1

Requires PHP 8.4 or later within PHP 8 and ext-json. Real completions also need a separately installed, authenticated Codex CLI on macOS or Linux. CLI versions 0.159.2 and 0.159.3 remain supported. Development subprocess checks require ext-posix.

No connector API, execution profile, supported CLI, or retention behavior changes from 0.2.0. serviceTier: 'fast' still requests Fast independently of reasoning; rejection never substitutes a model or tier. The Stage Chat dependency remains compatible with 0.1. Existing applications pinned to 0.2.0 are unchanged.

Validation: Composer metadata, PHPStan at maximum level, and 26 tests with 98 assertions passed locally on PHP 8.4.26. This distribution/documentation patch does not repeat a paid provider batch or change the previously verified wire profile. Repository automation stays disabled.

The application owns retrieval, authentication, concurrency, and output/source validation. CLI metadata and provider processing remain separate from the connector's content-file checks. No served-tier or latency guarantee is exposed. See README.md, docs/operations.md, CONTRIBUTING.md, and RELEASING.md.

Distribution verified: a fresh anonymous Composer consumer installed this exact tag and compatible Stage Chat from Packagist without VCS/local overrides, plugins, or development dependencies. JSON completion and the explicit Fast command profile passed through real subprocess pipes with the synthetic fake CLI. No authenticated provider call was made for this distribution check.
