Plate 01Calling is the endpoint; making is the start. Review shifts to the constraints of generation.

IN THIS ISSUE

Ten-minute reads

Vermilion for opinion, cobalt for tools

OPINION

One testable call per piece: if it is wrong, it should be possible to name the evidence that refutes it.

TOOLS

Reusable procedures and checklists. Short, but every step can be run; no conclusions without process.

NOTES

Only changes that shift judgement: model capability, tool interfaces, regulation. Not a news ticker.

The parts this publication is built from

TOOL
Content pipeline
Markdown in, validated index and prerendered HTML out; out-of-contract fields fail the build.
Live
NOTE
Bilingual pairing
Links only when translationOf is reciprocal; a one-sided pair is an orphan error, never path inference.
Live
TOOL
Semantic head
Canonical, hreflang with x-default, and OG tags generated per article.
Live
TOOL
Sitemap
sitemap.xml and robots.txt written at build time; drafts never reach the output.
Live
TOOL
Ink / Night themes
data-theme plus localStorage, written before first paint and kept across reloads.
Live
NOTE
TOC and anchors
Heading anchors generated at build time; TOC, reading progress and citations share one source.
In progress
TOOL
Font subsetting
Two families, two weights, self-hosted and subset to real usage; missing glyphs fail the build.
Planned
NOTE
Archive and search
Section and date archives plus site search, after the bilingual library stabilises.
