Trust is a build rule, not a writing style

AI may write the page. AI may not write the facts.

Useworthy separates sourced facts, deterministic calculations and editorial explanation. A release is blocked when protected facts drift, price maths disagrees, unsupported owner statistics appear, or market/canonical rules fail.

FACT

Source-controlled

Prices, market, currency, evidence level, source URL and snapshot date must match the approved Source of Truth.

CALCULATED

Recomputed

Price gaps, ratios and break-even boundaries are checked from locked inputs rather than copied from prose.

EDITORIAL

Explain, don’t invent

Editorial language may interpret a decision boundary but cannot create owner statistics, durability outcomes or unsupported facts.

What a release check looks for

UK transaction pages use GBP and UK price sources.
Displayed product prices match the approved price registry.
Comparison maths matches deterministic formulas.
Evidence levels match the product registry.
No owner aggregate is published before an owner dataset is established.
Canonical URLs and sitemap URLs resolve to the approved www host.
Unexpected fact changes block the build until explicitly approved with a source and reason.

What this does not claim

A release audit cannot make unknown evidence known. It is designed to prevent silent factual drift and calculation errors, not to manufacture certainty.
