Validation Roadmap

The first-class raw-output validation system is implemented. Current behavior is documented outside roadmap files, especially in Configuration, CLI Reference, Pipeline Internals, and JSON Output.

Implemented behavior includes:

a single raw module-output validator contract for chunk, extract, merge, and normalize outputs;
validator specs with deterministic and LLM-backed execution classes;
central production validator registration and default chain mappings;
stage-local config overrides that distinguish omitted, explicit empty, and explicit non-empty validator chains;
manifest provenance for resolved validator chains;
generic JSON validators and D&D spell validators under internal/validators;
production defaults for the dnd/spells extractor.

Future Work

Add production LLM-backed validators when there is a concrete review policy that benefits from model judgment.
Add validator diagnostics and timing summaries if operators need more detail than manifest.json, rejected.json, and warnings.json provide.
Add media-type validators for non-JSON module outputs when such modules are introduced.
Add compatibility metadata only if real deployments need config-time enforcement that a validator is suitable for a specific stage or module.
Add batching or context-window controls for LLM-backed validators if validator inputs become large enough to require them.
