The claim and the proof are different objects
“We manufacture this” is a supplier statement. It is evidence that a statement was made, attributed to whoever made it. It is not evidence that a specific factory produces your exact target at the specification you scoped.
The failure is rarely dishonesty. It is compression: three distinct entities — the organization that replied, the factory that produces, and the exact product you intend to buy — get collapsed into one sentence, and every later claim inherits the compression.
Keep three layers separate
Record each layer with its own source and state. A supported claim at one layer never promotes a claim at another layer.
- 01Organization: the legal entity that responded, and what it says about itself
- 02Factory: whether independent evidence attaches production to a site
- 03Exact product: whether the evidence covers your scoped target, not an adjacent variant
The smallest useful next request
When maker role is unsupported, do not escalate to a broader search. Ask for the narrowest artifact that would move the state: line-level production evidence for the named SKU, a process description tied to the scoped tolerance, or a third-party record that names the site.
If the request is refused or unanswered, that is a recorded state too. An unreached input is more useful than an assumed one.
