"""
TD Lang — Domain-specific language for Time Dilation project.

Compiles .td files into Python code that calls td_fuse.
Write simple scripts instead of complex Python.

Phase 1: load, merge, heal, eval, commit
Phase 2: diagnose, synth, train, debate
Phase 3: fork, reset, prune, edit
Phase 4: snapshot, report, data_contract, reward_contract
Phase 5: CLI polish, --version, info command, --verbose
Phase 6: fuse, absorb (easy merge)
Phase 7: repeat, if/else (loop control)
Phase 8: setup, on_error, notify, save (autopilot)
Phase 9: schedule (time-based execution)
Phase 10: download, log, compare, verify (toolbox)
Phase 11: vote, prompt, distill, rollback (intelligence)
Phase 12: curriculum, star, best_of, exploit (RL & fine-tuning)
Phase 13: arena (real RL with memory, curiosity, anti-lying, cross-check)
Engine upgrades: QLoRA training, self-contained eval, model-generated synth problems
Mega diagnose: self-diagnosis + domain profiling + layer speed testing

Designed from interviews test_14 (10 commands) and test_17 (ForgeSpec 2.0).
