Define explicit original, mixed and excluded file scope, credit nueex, and preserve historical MIT grants and third-party notices. Keep libjbc's redistribution permission unresolved and exclude third-party fonts, branding and imagery from the original-work grant. Retain the latest upstream build fixes and removal of obsolete tools. Application/build edits are licensing comments only; the production ELF and all 35 object files match the baseline byte for byte. No binaries or release artifacts are included.
