Use Python 3 with no third-party package. Copy this complete source directory, then run python -B CREATE.py /absolute/absent/output. An occupied or linked/overlapping output is refused before the first directory creation. If interrupted, preserve and inspect the marked partial output; do not rerun over it. Source authoring checkpoints and pair closure have separate registered resume records.

Run python -B CHECK.py inside the completed edition for the complete local source/default check. The seed binds all preferred page/asset bodies and per-item rights; the creator renders native closed help, original list ordinals and all table cells. The manifest records complete four hashes, modes and decimal nanoseconds for every other regular member. Directory/root stamps occur after final manifest writing.

The checks do not establish Browser, live delivery, classroom efficacy, audio, translation or whole-year completion. Rights · Portable full software licence · Complete terms
