Figure 11, Conservation status patterns; category changes; trajectory

1. Data inputs derived

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

Redistributable

No. IUCN Red List terms do not permit redistribution of the categories. The assessment identifiers and the rebuild route are deposited instead; this table carries counts, not categories.

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 2 artifacts below is served here, and carries a download link; the rest are named so the chain can be read, not followed.

1. Read the frozen intermediate. data/processed/iucn_historic_timeline.json
2. Compute and write the frozen numeric source data. visualizations/source_data/figureB_source_data.csv, download

3. LLM involvement: none

No generative model participated in producing this figure. The generator imports only csv, json, sys, collections, pathlib and the project's redlist_scale module, which is the one Red List scale and holds no model call either. 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: generated 2026-10-06; no named person has signed the binding and it is not yet independently confirmed. 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.
