IndustryForge 0.3.0 — the code of the deposited build of record First tagged release. This is the version that produces the 2023 build of record 2023_20260907-1114, deposited at Zenodo under 10.5281/zenodo.21979417 (CC BY 4.0) and described in the accompanying Data Descriptor submitted to Nature Scientific Data. Reproducibility, checked 2026-09-14: a fresh build of 2023 from a clean worktree, re-pulling every upstream source a week after the deposit, reproduces the published build exactly — grade warn, 69 QA checks pass / 9 warn / 0 fail, identical row counts on all 22 artefacts, and carrier totals equal to machine precision (electricity 1021.980, methane 995.000, oil 1084.209, biomass 277.072, coal 394.509 TWh). One deliberate mismatch: the deposited manifest records industryforge_version 0.2.0, which is what the package called itself when the build ran, no release having been cut. A build from this tag writes 0.3.0 into that field; nothing else differs. Input licences settled for this release: Light Metal Age (2026-09-12), SFOE/BFE ENSTAT (2026-09-08) and worldsteel (2026-09-07) granted re-use in writing; Concawe is unanswered and its fallback is documented in the deposit's LICENSE.txt.
