/claim #16

Summary

• Adds a distinct unit and dimensional consistency assistant for issue #16.
• Checks incompatible dimensions, dose/time conversions, rate denominator mismatches, missing normalization bases, impossible concentration conversions, and over-precise derived claims.
• Includes synthetic measurement packets plus deterministic JSON, Markdown, and SVG reviewer artifacts.

Non-overlap

This is separate from existing broad assistant, external-validity, structured-abstract, Bayesian, image-integrity, assay-control/calibration, literature-freshness, and randomization/blinding submissions.

Verification

• node ai-research-assistant/unit-dimension-consistency-assistant/test.js
• node ai-research-assistant/unit-dimension-consistency-assistant/demo.js
• git diff --check

All data is synthetic; no credentials, private research data, or external services.
