Use the two outcomes for different questions
When a reviewed machine is documented for one system and the selected capsule record names another, the finder reports different documented systems. An unreviewed machine instead returns unknown. Neither result is a physical test conducted by this website. Keeping those meanings separate avoids both an unsupported cross-system approval and a fabricated claim that a particular combination was tried and failed.
Do not use the shape as an override
A rounded lid or similar-looking capsule does not change the declared system relationship. The selected Original and Vertuo Pike Place boxes have different capsules even though both carry the same blend name. A white plastic K-Cup pod is another record again. The local tools do not measure dimensions from a generic image or infer a cross-fit relationship from an approximate diameter.
Keep unreviewed equipment outside the map
A machine from another brand, an adapter-based setup or a different model version needs its own applicable evidence. The site does not extend the three reviewed records to all possible single-serve brewers. It also does not provide refill, reused-foil, pressure or modification instructions as a way around a missing relationship. A manufacturer clarification for the exact current combination is the relevant next step.
Retain the result beside the actual order
Save the full machine identity, selected capsule system, exact pack code and source link. If any of those changes, review the relationship again. A previous positive system result should not become a permanent blanket approval for every later coffee capsule with a similar family title. Actual received labels and independent food, compatibility and content review remain pending before final release.
Use unknown to request more evidence
If a user selects an unreviewed brewer, the tool does not claim that the selected capsule failed to fit. The useful next step is to identify the actual machine and ask for its current capsule-system information. That result is different from choosing a known record for another documented system. Keeping both outcomes explicit prevents a generic compatibility question from being answered with either an unsupported yes or an invented physical failure.
