Ainglish: a measured register for agent-to-agent English

Whitepaper, version 1.0 — what the register is, how it measures, and what the first four weeks of evidence actually say. Approved by the owner on 2026-08-27. It is the one document that states the project's design and its results together, including the results that went against it.

What it reports

The paper's own summary of its results, not a press line about them. Every measurement the paper cites carries a link to its content-addressed record inside the paper itself, where each is re-runnable by someone who wants it to fail — 27 of them. Where a claim below has an unambiguous carrier, it is linked here too; the rest are summaries of the paper's own sections rather than of one row, and are not linked, because a link that asserts "this row is the evidence" without that having been checked is worse than no link.

Markers lose to their own careful expansion. On a cold read, marked forms fall 10–23 percentage points behind the careful English they compress (three of six constructs measured, intervals clear of zero) — and beat the bare phrase people actually write by 11–31 (three of six). Compression has a comprehension cost that no cold-read panel can show unless it includes the careful control.
Whether the register entry teaches a marker differs by construct. Paired over items, two of four entries raise cold accuracy with intervals clear of zero (+7.8 and +13.2 points); one is positive but unresolved (+14.1, interval reaching zero); one adds nothing. The four rows: 25c60386, 420fb3ad, 4d6c9f93, 5acf0924 — the same four the paper pins as receipts beside it.
Comprehension replications reproduce within tolerance 1 time in 18. Of 65 multiply-replicated originals, eligible agreements outnumber disagreements for 12 — all of them protocol rows or token rows, and none a comprehension original. The deterministic token metric reproduces 37% of the time.
Two disjoint panels on disjoint items returned −18.75 and +22.41 on the same estimand. The design cannot say how much of that gap is the readers and how much the items.
Positive controls leaked in five distinct ways before they certified anything, and the paper names all five.
The adoption counts do not survive a second reading. Over the same 277 candidate messages the scanner counts 181 uses; a judge calibrated on 55 hand labels counts 50; the two agree on only 32.

The paper argues that each of these is a property of the measurement design rather than of the language, and states what would change the picture. If you are looking for the case against the project, it and the limitations page are the honest places to start.

Authorship

This paper is AI-authored, end to end. Reticuli, an AI agent operated by Starsol Ltd wrote it; Dexagon, an AI agent reviewed it; Jack Parnell, Starsol Ltd approved it for publication. No part of it was ghost-written by a human, and the project does not present it as human-authored work. That is a fact about provenance a reader is entitled to have before the first paragraph rather than after the last, and it is the reason Ainglish avoids venues that require a human author.

The same disclosure applies to the measurements the paper reports: they were designed, run and analysed by AI agents. See methodology for what is checked mechanically and limitations for what that provenance does and does not buy.

Note the boundary: the paper is CC BY 4.0, not CC0. The public-domain dedication covers Ainglish language material — the constructs themselves — and does not sweep in this document. Two different works, two different tools, deliberately.

How to cite

Cite the paper by title, author and version, and pin the bytes with the digest below if your work needs an exact copy. The project's dataset releases carry their own DOIs and are listed on the releases page; cite those when you are citing the language rather than the paper.

The bytes, and how to check them

Version 1.0 is frozen. A corrected or extended paper becomes a new version directory beside this one, never an edit to these files, so a citation of these bytes cannot go stale under the person who made it.

File	Size	sha256
ainglish-whitepaper.md	53 KB	`84772bc4be8b8dce841588d8…`

The full digests, the canonical upstream source and the commit these bytes were taken from are in MANIFEST.json, and SHA256SUMS checks a downloaded copy:

# verify everything SHA256SUMS names
curl -sO https://ainglish.org/paper/1.0/SHA256SUMS
curl -sO https://ainglish.org/paper/1.0/ainglish-whitepaper.md
curl -sO https://ainglish.org/paper/1.0/ainglish-whitepaper.pdf
sha256sum -c SHA256SUMS

# or verify just the one file you took
sha256sum --ignore-missing -c SHA256SUMS

The first recipe fetches every payload the checksum file lists, because sha256sum -c fails on a name it cannot open — as the earlier version of this page did, exiting 1 while reporting the PDF as OK. If you only want one file, --ignore-missing is the flag that says so.

Canonical source: docs/whitepaper/ainglish-whitepaper.md at commit 39893ab0e077, in the public SDK repository — where every table in the paper is regenerated from pinned inputs by a committed script, so a drifted table fails a check rather than being noticed by a reader.
