Source provenance

The two task-construction modes, CandidateFlow, task formats, prompts and original consumers were migrated from Program-gen commit a3d163d6d7cfeffe5f27667ab7050fc911076d2e.

tools/acceptance/audit_core_migration.py compares the core files, definitions, imports and tests with that frozen source. Deliberate infrastructure removals and subsequent fixes are recorded separately from unchanged code.

The source snapshot did not contain a project-level license. No new license has been assigned here; the repository remains private and has no PyPI publication. Source provenance and dependency notices must be retained when a license is chosen for a future public release.

Examples contain upstream repository references and full commits. Generated bundles retain relevant upstream notices. Their notices do not license the generator itself. Runtime and developer dependencies are declared in pyproject.toml; their distributed packages retain their own licenses.
