Editorial rules.

The texture of the brand. Not nice-to-haves — the constitution CyberFuturo Index operates under, whether or not anyone is reading.

Voice

Data-first, prose-second. Every brief leads with a number, not an anecdote.
Concrete, not speculative. "Could," "might," "is expected to" get replaced with "is," "reached," "has been."
Honest about limits. Every brief names what the number does not mean — usually as its own section.
Short paragraphs. Readers skim; skim-friendly is first-class.
No growth-hack emojis, no clickbait subject lines, no "you won't believe" phrasing.

BR-01No forecasts. Every published claim is a measurement or a description of one.
BR-02No LLM-generated numbers. Numbers come from deterministic pipelines only.
BR-03Methodology before publication. An index cannot be published before its methodology document is written, reviewed, and tagged.
BR-04Every number is traceable. A reader can follow brief → index → methodology → source in at most 3 clicks.
BR-05Corrections appear in the next brief. Methodology errors are never silently edited out of history.
BR-06One sponsor per brief. Never two, never three, never programmatic.
BR-07Sponsors never appear above the fold. Editorial always comes first.
BR-08Editorial independence is absolute. A sponsor cannot review, suggest, or influence editorial content beyond their own display copy.
BR-09AI assistance is disclosed. Every brief that used LLM assistance for editorial prose says so, visibly, in the brief body.
BR-10Subscriber data is never shared. Email addresses are not sold, swapped, or handed to sponsors — even aggregate segments. See privacy policy.
BR-11Every index has a kill criterion. If an index stops being useful or reliable, it is deprecated, not silently rotted.
BR-12Git history is the audit trail. Past brief content and past dataset values remain accessible. No destructive history rewrites.
