Engine versions and what changed

Second wave of the independent scoring audit

Sixteen findings from the 2026-08-20 independent audit closed in one release. Two of them can move a page grade; the other fourteen are internal corrections with no visible effect on scores.

• Recency: the date you show readers must match a date you declare to machines. A date-shaped string anywhere on the page used to be enough.
• A+ now requires an unrounded full score. Pages that rounded up from 99.5 to 100 were getting A+; your points are unchanged, only A+ eligibility tightened — so a report can show 100 points with an A.

Measured — Measured before release: in our frozen reference set one target of six moved (Wikipedia, 100 → 94, because it declares 2001 to machines and shows 2026 to readers); the broken-page corpus did not move at all.

First wave of the independent scoring audit

An independent review of the scoring engine produced 23 confirmed findings. This release closed the high-severity half.

• Pages that read like an article but carry no article markup are now graded as articles. Deleting markup no longer raised a grade.
• The robots.txt and X-Robots-Tag readers were corrected, and robots rules are now evaluated against the page a redirect actually lands on.
• A crashed rule can no longer inflate a score silently — the report is marked degraded instead.

Page-type detection: dominance instead of counting

A page with several <article> elements was blindly treated as a listing, which under-measured real articles that happen to embed related cards.

• If the largest article carries at least 60% of the page text (and at least 500 characters), the page is measured as an article rather than a collection.

Four layers instead of three

The score was restructured so that each layer answers one question a reader can check.

• Layers became Access 25 · Indexability 25 · Answerability 30 · Recency 20. Recency became a layer of its own instead of a check inside another layer.

Semantic section signals

Two scored checks were added using a frozen multilingual embedding model, pinned to a fixed revision and run on CPU so the same page always yields the same number.

• Answerability now measures whether a section actually answers its own heading, and whether sections stand on their own when quoted out of context.

A+ means a full score

The grade definitions were tightened to match the published plan.

• A+ now requires a full score and zero warnings. A page scoring 97–99 without warnings is an A.
• Warnings do not change the number; their only effect is on the grade.

First prototype

The first working engine: an AI-crawler matrix over robots.txt, a JavaScript dependency measure, content freshness, a severity-weighted score and the partial-coverage cap.

No change that moves an existing grade.
