4. Verification and reproduction

4.1 What is verified

Table	Rows	State
hed_task_to_atlas.tsv	103	Every row checked against the archived Atlas record
atlas_task_to_hed.tsv	857	Every row assigned a match type; every matched row checked
hed_process_to_atlas.tsv	172	Every row checked against the archived concept definition
atlas_concept_to_hed.tsv	918	Every row assigned a match type

Two things in these tables are not hand-checked. The scope_class on an unmatched Atlas task is derived from its name by rule. And the none verdicts on the reverse tables assert only that no counterpart exists in a catalog of 103 tasks and 172 processes, which is the expected answer for most of an 857-entry and 918-concept corpus.

4.2 Reproducing the tables

python src/fetch_cog_data.py        # refresh the API archive in .cog_data/
python src/build_atlas_maps.py      # refresh the mapping tables

The second command is non-destructive. It never overwrites a match type, a mapped id, or a curator note. It refreshes the descriptive columns, re-deriving them from whichever id the curator chose rather than from the automated candidate, and reports entities that have appeared in or disappeared from the Atlas since the last run. Running it twice leaves the tables byte-identical.
