Rebuild the complete portable resource

Use Python3 with bytecode writing disabled: python3 -B CREATE.py /absolute/absent/output. Then python3 -B /absolute/absent/output/CHECK.py. The creator checks admitted seed hash, complete source/art/rights contracts and literal output/ancestor paths before its first mkdir. Occupied, linked, special and overlapping destinations are rejected. Preserve an interrupted .BUILD-IN-PROGRESS destination and inspect it; do not overwrite it. Completed files, directories and parents are fsynced. This is finite normal execution protection, not a forced crash or hostile concurrent-swap guarantee.

SOURCE-MANIFEST binds full namespace/body/mode/nanosecond properties; the checker reads every reconstructed member, local door, field, source-own-staff/fullalt and national/rights relationship. Current and sole fresh reconstruction are source evidence; different whole source/art review and actual Browser remain separate. Static hosting may be needed under browser local-file rules. No external assistant/API is enabled. Start here.
