Use Python3 with bytecode writing disabled. CREATE.py takes an absent absolute ordinary output folder and checks the literal path/ancestors before its first mkdir. It rejects occupied, linked, special or overlapping paths. If interrupted, preserve the .BUILD-IN-PROGRESS folder and inspect it; do not overwrite it or rerun against that occupied destination. This is finite prewrite protection, not defence against every concurrent hostile swap.
Run: python3 -B CREATE.py /absolute/absent/output from your retained bank. Then run python3 -B /absolute/absent/output/CHECK.py. The checker reads complete namespace, bodies, full modes and nanosecond stamps, local doors, fields, numbering and source relationships. It creates no output. Completed files/directories/parents are fsynced; this is not a forced power-loss guarantee.
Use README.html for the ordinary entry or interactive/index.html for the temporary bench. Static HTTP hosting may be needed for a browser’s local-file policy. No external assistant/API is required. Source reconstruction passes are distinct from actual Browser, publication, native export, classroom evidence and annual coverage. Preserve licence/source notice files with adaptations.
