Tier 2 (autonomous) hit a dilemma in Phase 9:
Plan said: do not change the audit heuristic.
Plan also said: classify-as-suspicious laundering is forbidden.
Reality: 6 of 8 Phase 9 sites migrated via narrowing are now classified as
UNCLEAR by the audit because the existing heuristics don't recognize
their drain patterns (return ErrorInfo, set empty default, err_item dict).
This contradicts the plan's preconditions for completing the track.
Options documented for Tier 1:
A) Add 1-2 audit heuristics (recommended, ~5-10 min work)
B) Full Result[T] migration of 6 sites (~30-60 min work)
C) Defer to Phase 11 (plan-divergent)
No source code changed. Awaiting Tier 1 decision before Phase 10.
