OpenEconometrics Codex plugin 0.1.3

Install the local OpenEconometrics plugin in Codex to inspect imported datasets, fit supported models, manage background analyses and read saved results. Supported runtimes return publication LaTeX, inference/sample notes and package requirements without refitting.

Extract openeconometrics-codex-0.1.3.zip and follow INSTALL.md. The archive includes a complete local marketplace and ten source-identical plugin files. Configure your own existing local runtime/workspace; no research data, credentials or runtime are included. Restart the Codex connection after installation.

Version 0.1.3 points to the public repository and preserves plugin identity. 154 focused cases, manifest checks, ZIP readback and two fresh Codex connections passed. Saved synthetic OLS readback is identical across restart and keeps the existing workspace unchanged. Public provenance records the exact package hash.

The selected runtime determines methods and optional LaTeX support. Older separately installed runtimes may provide structured output until upgraded. This plugin archive does not upgrade the desktop app, establish Windows execution or provide an account marketplace listing.
