Verified against Shopify's live rate engine: samples free, redundant $24.95 gone,
>$30 roll not free, $0-30 band intact, accepted 8-sample cliff confirmed. All 5
invariants PASS x3 consecutive sweeps. Read-only; no store writes.

+# /5x REPORT — TK-11333 sample free-shipping (live Shopify)
+
+Target: LIVE shipping behavior on designer-laboratory-sandbox (no web app — verified
+against Shopify's authoritative rate engine `draftOrderAvailableDeliveryOptions`, the
+same engine checkout uses; real-browser storefront checkout omitted because it would
+create live carts on the production store).
+
+| Sweep | Passed | Caught | Fixed | Result |
+|------|--------|--------|-------|--------|
+| 1 | 5/5 | 0 | 0 | CLEAN |
+| 2 | 5/5 | 0 | 0 | CLEAN |
+| 3 | 5/5 | 0 | 0 | CLEAN |
+
+Stop condition met: 3 consecutive clean sweeps (≥2 required). Cap not reached. No
+fixes were applied — nothing was caught, so nothing was papered over.
+
+## Invariants verified each sweep
+- INV1 samples free — 6-sample cart ($25.50) offers "Free Shipping (No Tracking)" $0.00 ✅
+- INV2 redundant rate gone — no "Priority Sample Only" $24.95 in profile OR on a $17 cart ✅
+- INV3 no over-generous leak — $168 / 4 lb roll gets NO free shipping ✅
+- INV4 free band intact — General Domestic "Free Shipping (No Tracking)" $0, condition $0–$30 ✅
+- INV5 accepted cliff (expected, not a defect) — 8-sample cart ($34) is NOT free ✅
+
+## Open items
+None from verification. Known/accepted by Steve: GAP 1 (8+ samples charged) and GAP 2
+(regular products ≤$30 ship free untracked) — both structural to a price band, no cheap
+clean fix (weight band refuted; dedicated profile broken; Plus overkill).
