Figure 4, Temporal heatmap of IUCN Red List status evolution

1. Data inputs derived

Computed from the figure pipeline's declared tables and query.

Database schema

arctic

Tables

iucn_assessments, species

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.

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.

1. Aggregate from Postgres. visualizations/data_processing/generate_iucn_timeline_pg.py
2. Intermediate JSON. data/processed/iucn_historic_timeline.json
3. Render. visualizations/scripts/figure5_status_heatmap.py
4. Frozen numeric source data. visualizations/source_data/figure5_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.
