Update or draft documentation for the specified scope.

Scope: $ARGUMENTS

Instructions

1. Read the relevant source files and any existing docs for the scope.
2. Determine what documentation is needed:
   • SDD update: if the implementation diverged from docs/specs/SDD_<slug>.md, update the spec to match reality.
   • Context README: if summary.md or README.md is missing or outdated for a bounded context, create/update it.
   • API docs: verify SpringDoc annotations (@Operation, @ApiResponse) are accurate and complete.
   • Architecture decision: if a notable design decision was made, document it with context and trade-offs.
3. Keep language consistent with the existing bounded context terminology.
4. All output must be UTF-8 Markdown.
5. Do not invent behavior — document only what the code actually does.
