-- Output summary: smoke script passed. Current script validates whitelist enforcement, fallback POI emission for unmatched public exhibition spaces, entrance coordinate preference, space-center fallback when entrance coordinates are missing, and sourceConfidence semantics.

+Output summary:
+- Smoke script passed. Script now validates:
+  1. Finding 1: entrance-derived sourceConfidence branch — entrance-backed halls with nodeId must be `backend-sgs-sdk-hall-entrance`
+  2. Finding 2: enforce entrance/reachable-node semantics — entrances without nodeId that match spaces use space-center sourceConfidence, not hall-entrance
+  3. Finding 3: avoid hiding duplicate names via Map-by-name only — added assertion that result names are unique, indexed by both name and id for duplicate detection
+  4. Whitelist enforcement prevents unrelated types
+  5. Unmatched exhibition space with center emits fallback POI
+  6. Entrance with missing coordinates falls back to matched space.center
+  7. Entrance still recorded even with undefined positionGltf (no coordinates)

+- `test: assert SGS hall POI route semantics`
 
 Self-review notes:
 - The script is standalone Node coverage for the intended adapter rules because this repository has no configured test runner.
 - The production adapter implementation is covered by Task 2 in the plan.
+- Fixtures now include:
+  - Space 8 (古生物展厅) with entrance 105 that has nodeId n105 for backend-sgs-sdk-hall-entrance assertion
+  - Place 107 (自然科学展厅 出入口) without nodeId to assert space-center semantics when entrance lacks routing identity
+  - Name uniqueness validation prevents silent duplicate masking
 
 Concerns:
 - None.
