# THE FIRST COLD RUN — the four-guardians function (2026-09-02)
# Owner's order: "I want to see how the code executes what the Mishnah
# says it does."
#
# This machine reads the CODE (Exodus 22:6-14) from the raw word
# database, with no tradition loaded, and:
#   1. PARSES the paragraph structure by the code's own case keyword
#      (verse-initial KI = case opener; the medial-KI senses are the
#      Gittin 90a dictionary's other meanings, excluded).
#   2. EXTRACTS each branch's event and outcome from ink tokens
#      (probe-tested per the zero-report law).
#   3. APPLIES the teacher's RECORDED moves, each labeled with its
#      source: the role diff (Bava Metzia 94b:8-9), the benefit seal
#      (94b:10), the loss a-fortiori (94b:15), the borrower-theft
#      comparison (94b:19), the renter routing (Mishnah Bava Metzia
#      7:8, hooked on the hire-clause in the ink of 22:14).
#   4. EMITS the liability matrix and GRADES it against the Mishnah's
#      recorded table (Shevuot 8:1 / Bava Metzia 7:8).
# Read-only; touches no unit; model layer.
