siera ships a plain-text library of analysis-method code templates (the `templateCode` + parameters + valueSource recipes that drive ARD generation) under `inst/method-library`. This accessor lists the available methods and resolves the on-disk location of a method's files, so you do not have to call [system.file()] directly. Each method's stable `id` is the key intended for an ARS file to reference.
Value
When `id` is `NULL`, a character vector of available method ids. Otherwise, the path to that method's directory (containing `method.json` and `template.R`).
Details
The human-readable catalog (`METHODS.md`) and the valueSource registry (`constructs.json`) live at the library root, i.e. `system.file("method-library", package = "siera")`.
