Taken: the layered prompt model, the shot-contract structure, the failure taxonomy, and
the version/run/selection/iteration distinction. Rewritten in English and rebound to
TongFlow's own mechanics (workflow files, numbered outputs, `.runs.json`, `{{path}}`
includes, per-run billing confirmation).

Not taken: the upstream project-folder schema and its CSV tables, and the bundled Python
tools — a dsh-tongflow project has no fixed template, and its provenance is recorded
automatically next to each asset.

That upstream project notes its own method was informed by publicly accessible production
material for Higgsfield's *Hell Grind*, and carries no rights to that film, its assets or
its project-specific prompts. Neither does this. Do not copy characters, assets or source
prompts from it into a user's project.
