# Plugin Config Catalog

Every `config:` block a `cordis.yml` entry can set: for each loadable harness package, the verbatim config declaration (JSDoc included) its `apply` function or service constructor receives, with every referenced type pasted alongside (package-local types) or linked (everything else). The paste is the plugin's full declared config type — a field the runtime schema deliberately excludes is a runtime-only seam (its own JSDoc says so) and is not settable from `cordis.yml`. This is the **deployment**-axis reference — the wiring a plugin author works against is the cordis [events](cordis-catalog/events.md) + [services](cordis-catalog/services.md) catalogs, the model-facing tool schemas are the [tool catalog](tool-catalog.md), and [core-data-structures/](core-data-structures/core.md) documents the types these declarations reference.

This file is GENERATED from source (`scripts/gen-config-catalog.ts`) and verified fresh by `pnpm run verify-config-catalog` (part of `doc-sync`) — do not edit it by hand. Declaration blocks use a `ts config-catalog` fence (skipped by doc-typecheck, since a lone declaration referencing imports is not standalone-compilable). The generator also cross-checks the runtime schemastery schema against the pasted declaration — every schema-validated key, nested keys included, must be locatable on the declared config type — so the paste cannot hide a loader-accepted field.

A `Requires:` line lists the service keys the plugin `inject`s: its `cordis.yml` tree must also load providers for those services. Scope is the harness tier (`packages/`); the vendored cordis plugins a config tree may also load (`hmr`, the console logger, …) are pinned upstream source ([vendoring policy](../vendor/README.md)) and not catalogued here.
