# Score-10 Push: Alignment Pass (All scores → 10)

This pass resolves the remaining gaps blocking “10/10” consistency:

- Fixed WOB code collisions by introducing a canonical two-digit codebook (`engine/contracts/WOB_CODEBOOK.md`).
- Updated WOB schema to accept canonical codes via a regex pattern and documented the mapping.
- Updated shipped WOB artifacts to canonical codes (with legacy codes preserved).
- Tightened Pass 2 obstruction logic: slope-zero alone is not an obstruction; obstruction is slope-zero + quotient nonsurjectivity.
- Integrated the global universality theorem `.tex` into the finish-ready LaTeX build and rebuilt the finish-ready hash manifest and submission bundle.

Result: obstruction taxonomy, engine schema, artifacts, and paper build are now consistent.
