Reproducibility Grades and Open Items
Every claim on this site carries one grade: [F] forced by the substrate, [V] reproduced and checked, [L] anchored to a cited value, [O] open with a stated obstacle. The engine is deterministic (two-run identical sha256), and writing was gated on a green five-target stress battery. The open items are the absolute cancer-risk magnitude and absolute organ size.
Grades: [F] forced, [V] verified, [L] calibrated, [O] open (obstacle stated). Determinism is enforced by a two-run identical-sha256 check (current hash 25900a90079a…); the open items carry explicit obstacles.
Grades used on this site
Every claim carries one grade. [F] forced means it is forced by the substrate with no freedom; [V] verified means reproduced and checked numerically; [L] calibrated means anchored to a cited literature value; [O] open means not yet reproducible, and every [O] states its obstacle.
| grade | meaning | example on this site |
|---|---|---|
| [F] forced | forced by the R19 substrate | RR(0)=1; no-threshold slope √γ |
| [V] verified | reproduced and checked | shared oscillator; RSA lock; Cheyne–Stokes 2× delay |
| [L] calibrated | anchored to cited values | resting HR; baroreflex gain/latency; HF-HRV band |
| [O] open | not yet reproducible (obstacle stated) | absolute cancer relative-risk magnitude; absolute organ size |
Determinism
The engine is deterministic: a two-run check produces identical sha256, and the current circulation hash begins 25900a90079acef5…. The site cannot be written until the stress battery is green and research is signed off; that gate produced this site.
Open items (C3 ledger)
| open item | obstacle |
|---|---|
| absolute cancer relative-risk magnitude | noise temperature (scale) and dose-to-bias conversion need external population-hazard calibration |
| absolute organ size | DWELL fixes relative size only; absolute magnitude needs external calibration |
Reproduce
Run python repro/run_all.py to emerge the organs, confirm the oscillators, pass the five-target stress battery, and print the oncology curve and gate status. The per-section reproduction scripts live in the GitHub repository under the matching slug.
