The script was added to package.json "check" in #129 but flake.nix buildPhase (the canonical hermetic gate) never ran it. Adds it early — after verify-vendor, before any page generation — so the deploy build fails closed on repeating identity keys in any data cut.

New post rendered by gen-blog.mjs like every other post: the color arc as narrative — perception has a resolution (JND) so the color space is finite; OKLCh axes (L=contrast, C=gamut-capped, H=free); the named-color collapse (maroon IS red, aliceblue lies); one-axis- multiply derivation; AAA mutes color by geometry; the pinned 8,149-color grid; construct- valid-not-validate, proven in Lean. Plain markdown, one github link. Verified locally: renders to dist/blog/colors-are-coordinates.html and appears in the blog index via gen-blog.mjs. Independent PR — blog content only; no build/script/token/nav changes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01V6j1N17T8exXeF8S6r99EM

A new blog post — the perceptual color model as an essay.
What it is:
blog/colors-are-coordinates.md— the whole color arc as narrative: perception has a resolution (the JND) so the color space is finite; the OKLCh axes (L spent on contrast, C gamut-capped, H free); the CSS named-color collapse (maroonisred,alicebluelies); one-axis-multiply derivation; AAA mutes color by gamut geometry, not taste; the 8,149-color pinned grid; and construct-valid, don't validate — proven in Lean.How it ships: plain markdown in
blog/, rendered byscripts/gen-blog.mjslike every other post — no new build steps, scripts, tokens, or nav. One external link (to the synopticcolor-model.mdon GitHub).PR checklist
blog/*.md. No build/script/token/nav changes.node scripts/gen-blog.mjsrenders it todist/blog/colors-are-coordinates.htmland lists it indist/blog/index.html(6 posts). Uses only the supported markdown subset (no tables).CI runs the full site gate suite (a11y, structure, SEO, semantic, link-graph); merge + the hermetic Nix/Cloudflare deploy remain gated behind that + human approval.
