+# Future Work
+
+Current Notarius behavior is documented in the canonical README, CLI,
+configuration, operations, internal, and integration docs. This roadmap records
+future work only.
+
+## Candidate Product Work
+
+- Additional input adapters, such as Markdown or note-export formats.
+- Additional D&D extractors beyond spell casts.
+- Cross-lane entity normalization.
+- Cross-chunk semantic deduplication.
+- Configurable validator chains with production validator modules.
+- Multiple effective LLM profiles in one run.
+- Parallel execution where it preserves deterministic manifests and diagnostics.
+- Additional output encoders.
+
+## Candidate Operational Work
+
+- Packaged release artifacts for alpha distribution.
+- A documented versioning and release process.
+- Optional generated example output fixtures with a regeneration procedure.
+- Additional diagnostics or reporting views if operator workflows need them.
+
+## Non-Goals To Revisit Deliberately
+
+- A general workflow language.
+- Structural module selection through ad hoc run flags.
+- Storing secrets in config files, diagnostics, manifests, or examples.
