Methodology

AisleLens publishes versioned buying standards — the questions a competent buyer asks in a category, written as executable tests — and runs them against your real product pages, reporting every requirement as proven, not proven, or requires store access, with the evidence.

A buying standard is the set of questions a competent buyer asks in a category, written down, versioned, and executable. AisleLens publishes them, then runs them against a store's real product pages — reporting every requirement as proven, not proven, or requires store access, with the evidence that decided it.

A buying standard is fixed at a version and a content hash, so a result can cite the exact contract that produced it and that citation still resolves a year later. A superseded version keeps serving its original bytes forever; a new version says what changed and names the entry each of its own entries continues.

We publish what we cannot test, and why: every standard states its blocked and advisory entries in full, alongside the ones that run — and it publishes the measured rate at which the engine executing it gets a requirement wrong, with the method, the sample, and the defect classes behind it.
