configuration_location

`importRoots` is an optional array of alias-to-directory mappings in `.reqlan/config.json`. Each mapping has: - `alias` ( required non-empty string ): prefix before `/` in aliased import paths. - `root` ( optional non-empty string ): directory for that alias. A relative `root` resolves against the base root ( the parent of `.reqlan` ), not against the `.reqlan` directory. An absolute path or `file://` URI is used as that alias' import-root directory directly. When `root` is omitted for a mapping, that alias uses the workspace folder that contains the `.rq` file. When `importRoots` is omitted, empty, or has no valid entries, the default is one mapping with alias `@` and no explicit root. When several aliases could match a path, the longest alias wins. Invalid or unreadable JSON, and a non-array `importRoots` value, fall back to defaults ( or no loaded config for discovery, then defaults at resolve time ). Language path forms and `@/` shorthand: ["../language/imports.rq".import_paths] and ["../language/imports.rq".configuration_import_root_alias]. Schema: [configuration_schema_file]. Applying file discovery: [configuration_location]. Editor completion of aliased import paths: ["./syntax/features-syntax.rq".code_completion].

The machine-readable JSON Schema for `.reqlan/config.json` is ["../../packages/extension/schemas/config.schema.json"]. The extension contributes that schema for `**/.reqlan/config.json` via `jsonValidation` in ["../../packages/extension/package.json"]. `.reqlan/config.json` is a JSON object. Unknown properties are not part of the schema and are ignored when loading.
