Corpus and context dependence of the Jacobian lens — artifact mirror
Fitted operators, experimental records and the corpus pool for the accompanying paper.
Licence. Everything here is CC BY 4.0, without qualification — see LICENSE. That is
true by construction, not by assertion: this repository contains only artifacts this work
produced. No third-party corpus text is distributed here. The corpus pool is rebuilt from its
public sources by repro/06_build_corpora.sh and verified against the manifests that ship here;
8 of 11 corpora rebuilt bit-identically when measured. ATTRIBUTION.md has the detail.
Layout
results/lenses/e28/ 166 operators + sidecars corpus x N ladder
results/lenses/plad/ 53 operators + sidecars per-layer activation dumps
results/lenses/ladder/ 15 operators + sidecars canonical model ladder (70m ... 2.8b)
results/lenses/misc/ 8 operators smokes and one-offs
results/<17 experiment dirs> per-experiment operators and records
results/*.json 190 experimental records
corpora/ 3 provenance manifests (NO corpus text — rebuild it, see ATTRIBUTION.md)
Every .pt is a corpus-averaged Jacobian J_l = E_x[dh_final/dh_l] fitted with the reference
implementation at pin 581d398, fp32, TF32 off, uncentered.
Reproducing
Every statistic in the paper recomputes from results/**.json alone — no operators, no GPU:
git clone <code repository>
uv sync && bash repro/01_setup_local.sh
bash repro/04_fetch_results.sh # pulls results/**.json from here, ~7 MB
bash repro/RUN_ALL.sh --tier T0 # 12 modules
--tier T1 re-scores the stored operators on CPU and needs the .pt from this repo
(bash repro/03_fetch_artifacts.sh --all). --tier T2 refits on GPU.
Provenance
Each results file carries a provenance block: the producing script and its SHA-256, the commit,
the argv, and the SHA-256 of every declared input. payload_sha256 covers the record excluding
the provenance block, so it is stable across reruns that change only environment metadata — rerun
and compare it, and a match means no number moved.
No hostname is recorded. Input hashes are the values at write time; where a record was later
redacted, payload_sha256_before_redaction retains the original so both remain verifiable.
No corpus plaintext is distributed — see ATTRIBUTION.md for the rebuild.
