"""
qaqc_review.py - Stage 6: senior architect full-set QAQC review (LLM).

One whole-set reasoning pass that surfaces QAQC issues BEYOND the direct
cross-discipline conflicts already found in Stage 5 -- missing sheets/schedules/
details, incomplete information, bid/permit-readiness gaps. Text-based over the
already-extracted assertions, clusters, and conflicts; emits the canonical issue
schema. Returns [] on failure.
