Official-source verification, or nothing

COFFER publishes confident claims only when an official issuer, airline or hotel source can be cited, captured and traced. Everything else is hedged, blocked, hidden or redirected.

Last updated · June 2026

The standard

Every confident public claim on this site — a benefit, fee, transfer ratio, eligibility rule, posting time, redemption rule — must satisfy all of the following before it appears:

  • It originates from an official source: the card issuer's own published documentation, the partner airline or hotel's own published documentation, or a written confirmation from those institutions.
  • An official source link and recorded verification datehave been captured: the source URL, the exact extracted claim, and the date the claim was verified.
  • The claim carries a verbatim quote from that document, and the engine has read it a second timeagainst the same source and reached the same answer.
  • The claim is officially verified or approved-fact-backedon the page that renders it.

What we explicitly do not do

  • We do not cite third-party blogs, forum posts or aggregators as evidence for confident claims.
  • We do not treat user submissions as verification. User submissions are a demand signal — they tell us which facts deserve verification effort, not what is true.
  • We do not publish a fact that failed its second reading, or whose quote could not be found in the official document. It stays hedged until the document says otherwise.
  • We do not publish redemption values, INR-per-point estimates, transfer bonuses, or "best for X" rankings unless the underlying inputs are themselves officially verified.
  • We do not accept payment to alter a fact, hedge, or ranking.

How a claim becomes public

  1. The engine reads the issuer's own official documents — the product page, the terms, the fee schedule, the tariff.
  2. It extracts each fact with the verbatim sentence it came from, the source URL and the date it was read.
  3. It reads the source again and checks the fact against its own quote.
  4. A fact that survives that double-check is published automatically. A fact that does not stays hedged and is not stated with confidence.
  5. The public page renders the fact with its source trace and last-verified date.

There is no human approval queue standing between a verified fact and this site. Where a document is genuinely ambiguous — two readings, both defensible — the engine stops and puts a single either-or question to the owner. That is rare, and it is the only point a person enters the process.

What you see when a claim is not verified

Pages where official evidence does not yet exist are intentionally hedged, blocked, hidden from the public sitemap, or redirected to a verified hub. You will not see a confident transfer ratio, a confident INR value, or a confident "best card" recommendation unless that specific claim has cleared the workflow above.

Corrections

If you spot a confident claim that is not source-traced, email editorial@coffer.gold — we hedge or remove within 48 hours and rebuild only after the official source is captured.
