Summary

  • The published tail word keeps the 4,058-event channel prefix. Its only add of X0 into Y34 is event 5759, with coefficient -1/2.
  • That value is 0 - G/2 for the same ports whose normalized inner product is 1. The channel prefix ends at +1/2, so the two published coefficients sum to 0.
  • No selected frontier change and no new exponent. The 280-column identity and the host schedule are not replayed.

Test plan

  • python3.12 -B research/p104-tail-flag0-coefficient/verify.py
  • python3.12 -B research/p104-tail-flag0-coefficient/test_verify.py
  • python3.12 -B scripts/research_package.py --package research/p104-tail-flag0-coefficient
  • Confirm the registered replay on the maintainer's Python 3.12 checkout

Made with Cursor

Event 5759 adds -1/2 times X0 into Y34 after the unchanged channel prefix. The channel ends at +1/2, and the two coefficients sum to 0.
