Input from Gemini 3 Pro:
✦ I have completed the tasks for this issue:
- Created the new technical guide
learn/guides/devindex/data-factory/DataEnrichment.md.- Documented the mathematical implementation of the Heuristics Engine (Velocity, Acceleration, Consistency), explicitly explaining the use of the median baseline for calculating acceleration.
- Documented the multi-tiered parsing strategy of the Location Normalizer, detailing the regex boundary matching, the US State abbreviation collision handling, and the fallback city map.
- Updated
learn/guides/devindex/tree.jsonto insert the new guide into the Data Factory section.The code has been committed and pushed to the
devbranch. Closing this issue.

The
Heuristics.mjsandLocationNormalizer.mjsservices provide critical data enrichment during the Updater phase. While the high-level concepts are mentioned inMethodology.md, the technical implementation details—such as the median calculation for acceleration or the regex boundary logic for locations—belong in thedata-factoryengineering documentation.Tasks:
learn/guides/devindex/data-factory/DataEnrichment.md.Heuristics.mjs(Velocity, Acceleration, Consistency).LocationNormalizer.mjs.learn/guides/devindex/tree.jsonto include the new guide under the Data Factory section.
