The numbers in this figure
26 rows from figure2_source_data.csv, read out of source_data.zip in the deposit. Not a copy: the page reads the archive a reader downloads, so the two cannot disagree. The filename carries the pipeline's figure number, which is not this figure's number; the archive's index states the binding.
The archive's digest: 3558736147e731a25c113309a5af49e534421701d97c1324ddf703aed3d45266

Binding curated
trade-enforcement · pipeline artifact figure2 · binding confirmed by panel titles against the caption on 2026-08-14
Binding evidence, as the record states it: CONFIRMED 2026-08-14, and REBOUND from figure1. figure2_trade_enforcement.py builds three named panels: '(a) Top 10 Most-Traded Species', '(b) Trade by CITES Appendix', '(c) Trade by Purpose Category'. The manuscript caption is 'Top 10 species by trade volume; by IUCN status; purposes; appendix'. Three of the four elements match by name. figure1_publication.py builds wild-origin panels instead ('Top 15 species by wild-origin trade'), which is manuscript Figure 6's subject and is already bound to figure8. The earlier note said neither candidate carried a trade-purpose column. That was read off the Source Data header, where the column is named most_recorded_trade_use, and off the wrong artefact: the panel is built in the script, which references it explicitly at 'Panel C: Trade purpose categories'.
1. Data inputs derived
Computed from the figure pipeline's declared tables and query.
- Database schema
arctic- Tables
species,cites_listings,iucn_assessments,cites_trade_records- Database release
- CITES Trade Database v2025.1
- Extraction date
- 13 June 2025
- Redistributable
- No. IUCN Red List terms do not permit redistribution. Assessment identifiers and the extraction script are deposited instead.
The figure pipeline reads schema arctic (v1). The deposit is built from arctic_v2. Row counts can differ. A reader regenerating this figure from the deposit may not reproduce the published numbers exactly.
2. Processing steps derived
Each step is a path in the figure pipeline's own repository, which this site does not host. Regenerate and verify commands are literal. 1 of the 4 artifacts below is served here, and carries a download link; the rest are named so the chain can be read, not followed.
- Aggregate from Postgres.
visualizations/data_processing/export_cites_effectiveness_pg.py - Intermediate JSON.
data/raw/1_DATA_cites_effectiveness.json - Render.
visualizations/scripts/figure2_trade_enforcement.py - Frozen numeric source data.
visualizations/source_data/figure2_source_data.csv, download
Regenerate: ARCTIC_DATABASE_URL=... ./.venv/bin/python visualizations/make_all_figures.py
Verify: append --check. This regenerates the source data from the database and byte-diffs it against the frozen copy. Byte equality means the whole chain from database to figure numbers is deterministic.
3. LLM involvement: none
No generative model participated in producing this figure. The artifacts named above import only csv, json, numpy, pandas, plotly, pathlib, collections and the project's psycopg2 helper. No model API is called at any step, and there is no prompt because there is no model.
This is asserted mechanically rather than by declaration. visualizations/tests/test_no_model_calls.py reads this manifest, opens every script and generator it names, searches for model SDKs and API clients, and fails if it finds one. It covers every script and generator the manifest names.
The generative model in this project drafted 343 narrative prose sections about the 43 species. None of that prose reaches any figure, and none of it is displayed on this site: it is withheld pending expert review.
No review has begun, so there is no agreement statistic to report and no page reporting one. What can be checked is that the withholding is complete: the drafts are deposited unrendered as supplementary/species_narratives_no_citations.csv, every species page states how many of its sections are withheld, and the dataset page marks the table as unreviewed content.
4. Validation
Automated gate: passed. Byte-exact regeneration from the live database against the frozen source data.
Human review: no named person has signed this figure. withheld The automated gate establishes that the numbers are reproducible from the database. It establishes nothing about whether they are the right numbers to plot. That judgement requires a person, and no person has recorded it.
Known defects: none recorded. The automated regeneration gate passed and no defect has been recorded against this figure. That is a statement about what is known, not a guarantee that none exists.
