The documents
This site was commissioned by a brief pack, and the pack is published here whole rather than summarised away. Each document has a reader page with its summary, key concepts and key ideas, and then renders the original markdown in place. The raw markdown under /briefs/ is the source of truth, and it is fetchable at a stable constructed path.
The pack, in reading order
The brief pack: what it is and how to read it
The corpus behind the material, the reading order, and the three things worth the most attention: one working twin, one naming collision, one uncomputed number.
Read → Start here · 1.3k wordsThe brief: twins.sgit.ai
The thesis, the four original ideas, what is actually built, the naming collision, the corpus numbers, and the build order.
Read → Tier 0 · 0.9k wordsThe twin primitive
Definition, doorway, connectedness, the discipline of reality, fractal structure and stacking, twins as actors, testability.
Read → Evidence · 0.7k wordsWhat is built, and where twins are applied
The S3 container as the worked proof, the AWS twins, and the nine-application map with owner sites.
Read → Tier 0 · 0.7k wordsThe broker, and the naming collision
The execution broker, the boundary it closes, its two costs, and the ruling that keeps the word usable. Carries a provenance note.
Read → Build · 0.4k wordsSite architecture
Page by page, the house pattern, and the name-watch check that became this site's release gate.
Read → Governance · 0.4k wordsBoundaries and licensing
Licence, provenance notes, do-not-publish trees, network boundaries, and house style.
Read → Gaps · 0.7k wordsGaps, open questions and honest tensions
Six build-fresh items, five open questions, five tensions, five loose ends.
Read →The source manifest
The pack carries a manifest of the corpus documents behind it, tiered 0 to 3, with every path verified on disk at the time it was assembled. Two rows are marked do-not-publish: an investor tree, and the governance records that name a private individual. Neither is quoted anywhere on this site.
09__source-manifest.csv — the manifest, as supplied.
