# Directional Improvement Passes (Next 10)

These passes are designed to push SFT from a strong framework into a referee-hard, artifact-backed theory.

| Pass | Goal | Core deliverables | Acceptance gates |
|---|---|---|---|
| DI Pass A | Engine artifacts first | example WSC and WOB JSON files for each witness tier | every tier has at least one valid WSC or WOB passing `audit_wsc.py` |
| DI Pass B | Arena-level universality theorem | a lifted version of AWT from slice level to sliced arenas, including FEQ invariance | theorem statement is explicit; hypotheses checklist is complete |
| DI Pass C | Embedded witness library | a small library of canonical ESW templates (vortex loop, ring, latitude, waveguide) | each template includes a WCT and a WSC margin recipe |
| DI Pass D | Coupled atlas | parameterization of CST targets and coupled Haar baselines across coupling classes beyond SOL | at least two coupling classes beyond SOL are formalized |
| DI Pass E | NDB derivation track | one scoped derivation: noisy phase sampling ⇒ diffusion in phase density | the modeling bridge is stated as a proposition with assumptions |
| DI Pass F | Quantitative convergence bounds | explicit rates in SUD/FUD under MXC, including coupled targets | a rate table is added to `constants_thresholds.md` |
| DI Pass G | Obstruction engine | WOB taxonomy refined into an output-ready obstruction pipeline | every WOB code has an evidence checklist |
| DI Pass H | Referee map completion | a complete referee map for the paper skeleton with artifact pointers | no claim remains unsupported or unscoped |
| DI Pass I | Example pack | one fully audited worked example: Earth + SOL coupling + WSC + diagnostics | all artifacts validate; example is copy-ready for paper appendix |
| DI Pass J | Submission polish | paper skeleton upgraded into a draft with integrated universality section and engine artifacts appendix | claims discipline is tight; appendix references are correct |


## Status

- Completed: DI Pass A–J
- Next: convert PAPER_SKELETON.md into a full LaTeX draft using the integrated universality and engine appendix.
