From db1044717f2bdc7c50ff6bb04da68b8eed230a17 Mon Sep 17 00:00:00 2001 From: Ebin Date: Sun, 6 Sep 2026 16:18:11 +0530 Subject: [PATCH 1/2] Generate README figures from the artifacts, and gate them with the explainer explainer/build.py now writes six standalone SVG figures under explainer/figures/: the T1 and T4 full-chain rows side by side, and each scenario across its three safeguard arms, in a light and a dark variant. They are drawn by the same gate-chain code as the explainer page, which was split into a view derivation and a drawing step so a one-step T1 leg and a three-step T4 leg render through one path. Every value in them is read from the committed artifacts; nothing is hand-typed. build() returns the figures beside the two page wrappers, so main() writes them and --check compares them byte for byte, and the Pages workflow now refuses to deploy if a figure has drifted. Its operator hint names the figures directory. The figures carry an inline stylesheet, system font stacks and no external references, so GitHub can render them, and labels that sit on a gate bar are painted with a background halo. Two tests are added: each figure states the outcomes and side-effect counts of the rows it draws, read independently from the artifacts, and no figure carries a script, a link, or an external URL.

A new section, "How the experiment works", carries two Mermaid diagrams: the gate chain from the frozen contract to the checkers, and the capture-and-replay path that makes the three arms comparable. Every number, link target and fenced block from the previous revision is unchanged; the numeric claims were compared as a multiset before and after. tests/test_readme_figures.py pins that every relative image path in the README resolves to a file, that each picture element pairs a light file with its -dark variant, and that each Mermaid fence names a diagram type.
