One sponsor. One page. One day.
One sponsor, one page, one day. The slot is labeled everywhere it appears — including to AI engines — and it cannot touch a score, a ranking, or anything in the citation layer.

settlement is fail-closed: 1 commissioning requirement(s) outstanding. Checkout stays fail-closed until the stablecoin commissioning gates clear. Blocking requirements: a named PSP/custody provider contract, mainnet custody evidence, a manual recovery and refund drill, and named legal and compliance approvals.
Crypto settlement has no chargeback. A misrouted payment at this price is unrecoverable, which is why the gate exists rather than a warning label.
You can still reserve a page and date below. The request reaches a human, who will confirm availability and arrange settlement directly, no payment is taken through this page until the gates clear.
What 10,000 USD does not buy
Index and score pages carry rankings, and governance pages carry the rules that make the rankings trustworthy. Neither is ever for sale, so neither can carry a sponsor.
- A score, a ranking position, or inclusion in any Index
- A favourable finding, or the softening of an unfavourable one
- Faster correction handling, or the removal of a correction
- Placement on an Index, score, or governance page
- Any change to an article's abstract, sources, cluster, or citation metadata
- Editorial review of the sponsor's own copy before it publishes
- Exclusivity beyond the single page and day purchased
How the slot appears
On the page: Rendered as a labeled aside marked data-sponsored, visually distinct from editorial, never inside the article body.
To machines: Declared as schema.org WebAdvertisement. Never described as editorial, and never added to abstract, about, isBasedOn, citation, or any ranking field.
To AI readers: Markdown only, in a dedicated sponsor block on /sponsors.md. No HTML, no schema injection, no placement inside the citation layer — an AI reader sees plainly labeled sponsorship text and nothing that resembles a finding. See /sponsors.md.
A human confirms every slot
A booking is a request, not an automatic placement. The operator confirms every slot by hand before it renders. No sponsor goes live without a human saying yes. At this price, on a desk whose whole asset is trust, an unattended placement is the one failure that cannot be corrected after the fact.
The operator is notified on every booking request, without exception.
Repricing
A rate change never applies retroactively to a booked slot; a confirmed booking holds the rate it was booked at. Repricing is done by the operator.
Reserve a page
Exclusive for the day you choose. Index, score, and governance pages are not listed because they are never for sale.
Public sponsor ledger
Every sponsorship is public: who, which page, which day, what they paid. A sponsorship a reader cannot see is indistinguishable from influence. Publishing the ledger is what keeps the slot honest and keeps the desk answerable for taking the money.
No page on this site currently carries a paid sponsor.
