Set by the leaf skill on every finding it emits. The super-skill preserves it verbatim when rolling a sub-skill's finding into its top-level `findings[]`, and sets it to `"Agent"` for the agent findings it emits about cross-cutting concerns. Consumers SHOULD render it verbatim and MUST tolerate its absence (older producers may not emit it).

 **`findings[].suggested-code`** — optional in the schema but **expected for mechanical findings**. It is a concrete code-replacement payload for the lines indicated by `location`. When present, the string MUST be a literal replacement for the source lines covered by `location.line` (or `location.range` if set) — i.e., what the file would contain after the fix, with no surrounding diff markers, fences, or commentary. Consumers MAY render it as a one-click suggestion in the delivery surface (for example, a GitHub ```` ```suggestion ```` block).
 
 Emit `suggested-code` whenever the fix is small, local, and mechanical: deleting unreachable code; replacing one expression (`Count() > 0` → `not IsEmpty()`); moving a local `Label` to object scope; adding a missing property such as `ToolTip`, `OptionCaption`, or `DataClassification`; replacing a string-concatenated `Error` with a Label-backed call; changing a permission token; or adding a missing `else`/guard branch whose replacement is unambiguous from the surrounding diff. When a `.good.al` companion exists and the diff context matches the `.bad.al` shape, prefer adapting the `.good.al` replacement into `suggested-code`.
