The guides explain enduring questions. This page is for the other thing a research operation produces: findings. A rate move and which tiers it actually reached, a provider whose own channels disagree, a measured result from the register. Each note is dated, each links to the permanent page it touches, and when there is nothing worth publishing, nothing is published.
What "who offers Islamic mortgages" actually resolves to once residency scopes, minimum finance amounts, waiting lists and unverifiable routes are read out of the providers’ own published pages.
Updates: the provider register, the comparison.
A note is published when the register produces something genuinely new: a verified change, a contradiction between a provider's own sources, or a measured answer to a question nobody had measured. There is no schedule, because a schedule is how findings get invented. The permanent state of the market always lives on the provider register, the rates page and the comparison; a note records the moment something moved, and the change log records every correction we have ever made.
