# D&D Shared Helper Refactor Completed

The D&D shared helper refactor is implemented.

Implemented package ownership:

- `internal/modules/sharedassets`: generic prompt filesystem composition and
  domain-neutral shared asset plumbing.
- `internal/modules/sharedassets/dnd`: reusable D&D prompt fragments, prompt
  filesystem composition for D&D modules, D&D reference slot helpers, prompt
  input assembly, reference rendering, and D&D shared prompt hash parts.
- Concrete D&D modules: stage contracts, module registration, module-local
  prompt definitions, response schemas, validators, request validation,
  response conversion, and manifest metadata ownership.

The refactor preserved module keys, prompt IDs, prompt versions,
Scriptorium-visible message order, response schema IDs and names, CLI/config
semantics, manifest shape, diagnostics redaction policy, and D&D scene/spell
interpretation behavior.
