Records with non-OSI license, restricted access, or experimental maturity without evidence are deferred to catalog-deferred.json.",
  "honesty_note": "v1 acceptance target is 5-10 cores. This file publishes 2 cores because (a) the upstream AccelFury cores.registry.json declares all entries under license 'AccelFury Source Available License v1.0', which is NOT on the OSI-approved list, and (b) the 4 fpga.chat internal demo cores in packages/sdk/src/build-v1.ts#buildV1DemoCatalog.cores carry a placeholder 'demo-catalog' license and are not reusable IP. The 21 AccelFury cores and the 4 internal demo cores are recorded in catalog-deferred.json with explicit reasons. The fpga-skillls restricted core (serdes-framing-engine) is also deferred. Demo scenarios continue to resolve against the SDK internal demo catalog at the fit-engine layer; they do not require public publication.",
