+# Task 1 Report
+
+Status: DONE
+
+Files changed:
+- `scripts/check-sgs-hall-poi-adapter.mjs`
+
+Commands run:
+- `node scripts/check-sgs-hall-poi-adapter.mjs`
+- 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.
+
+Commits created:
+- `3f049f2` test: cover SGS hall POI display rules
+- `5478986` test: strengthen SGS hall POI smoke coverage
+
+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.
+
+Concerns:
+- None.
