# R22 clean-fleet verify. EXCLUSIVE BY CONSTRUCTION, and it CLEARS THE DEFERRED-CHECK DEBT.
#
# `make clean` deletes asm/ AND build/. Four separate times in P31 S68 that raced a live lane:
#   * a subagent authorised to splice src/800.c -> a FALSE "212 passed, 1 failed" red;
#   * three drafting agents reporting "asm/<binary> is MISSING from the tree" mid-draft (one
#     survived only by finding an old snapshot under .run/s46 and still returned MATCH -- luck).
# Drafting agents never WRITE src/, which is exactly why a dirty-tree check does not catch them:
# they DEPEND on state this operation destroys. R54 -- a guard that is not running is not a guard,
# so this REFUSES rather than relying on the operator remembering.
#
# `.run/R22_DEBT` is written by `parallel_gate --r22` whenever it SKIPS its own clean-fleet check
# for the same reason. A deferred check that nobody tracks reads as "verified" at session close
# (R32's corrected form), so it is a file, the session checkpoint quotes it, and only a GREEN run
# here deletes it.
