347 headers said "Licensed under the StarForth License, Version 1.0" -- a shortening (Captain Bob, 2026-11-08: "License file SL I think I shortened accidently"); LICENSE is, and has been since the first commit, the Starship License 1.0 (SL-1.0, SPDX LicenseRef-Starship-1.0). 349 files, 566 occurrences, now "Starship License, Version 1.0 (SL-1.0)". Left as they are, pending a ruling: docs/patent/ (the patent figures), docs/formal/ (the citable volumes) and the generated reports under docs/working/experiments/ (32 files). Comments and license text only: the amd64 kernel builds, every changed script parses.
