Firefly and Sora on who the readers of a mark actually are

Both entries write manifests in a published format, and they describe entirely different reading populations. One points outward at an ecosystem; the other points inward at its own tooling. As of 2026-09-22.

Inclusion rule. Two entries whose published answers to one column pull in different directions. Cells hold each vendor's own wording from the page its entry names; pairs that agree on the column are not filed at all. Order. Fixed order, and the two columns are in the order the heading gives them.

1Pointing at an ecosystem is the available proof

Interoperability cannot be demonstrated by one company. Evidence that others are involved is the substitute, and a founding year with a membership figure is that evidence at its most compressed.

It is also the weakest number to lean on. Membership of an initiative is not the same as shipping software that reads a manifest, and neither page here enumerates the software.

2An honest internal boundary beats an implied general one

A vendor could describe a detector without saying who may run it, and many do. Naming the boundary lets a reader plan around it, which is what documentation is for.

So the narrower statement is the better-written one. It is still a narrower statement, and a file in the hands of somebody with no vendor relationship gets nothing from it.

3The layer, not the vendor, is what travels

Both entries rely on the same kind of published format for the part that reaches outsiders. Their own tooling, coalitions and detectors sit on top of that and do not change what the file itself can be read for.

Which is the useful conclusion from this pair: what makes a mark readable by strangers is the specification. Everything else on either page is about who happens to have built a reader.
