02 Hardcode Inventory Audit

Verdict FAIL. Inventory is incomplete and its no-go guard false-passes.

Missing/misclassified: fn_qt001_build_plan_registry hardcodes tier derivation with literal CASE/tier codes; tier eligibility rules are non-executed text; known-bad divergence is actual Tier3 decision despite claim signal-only; all plan rows get same literal blocked_reason; signoff SAFE semantics are weak hardcoded scope matching without current checksum; scale_not_safe literal true absent from inventory.

Hardcode guard PASSes while dangerous authority HC-05 is OPEN_NEXT_LAYER. A dangerous finding inside current Plan/Tier scope cannot count as eliminated.
