Authored structural fixtures for REA6.8.0, 2026-11-01. These are not runnable applications, a compiled BEAM module, or a Godot export. fixture.beam contains tables only and no Code chunk. fixture.pck declares engine4.4.1 but is hand-built. fixture-pyinstaller.elf has a minimal ELF header with no program or section table, followed by a synthetic CArchive; no bootloader/PYZ/bytecode. Truncated BEAM, mismatched MD5, and bare CArchive are deliberate negative controls. Python3 make-fixtures.py recreates the fixture bytes. No fixture executes code.
