+## 📝 GAIA / SDSS Real-Data Note
+
+We initially attempted to run the SSZ pipeline directly on the provided GAIA (and GAIA+SDSS) catalogues. However, the released tables did not match the assumptions of our analysis:
+
+- **Missing columns:** Several columns required by the pipeline were completely missing
+- **Different semantics:** Some fields had different semantics than documented
+- **Scale inconsistencies:** Key quantities (e.g. magnitudes and distances) were off by orders of magnitude compared to our internal consistency checks
+
+Because of this, any attempt to "fill in" the missing columns or rescale the data would have turned the test into a meaningless exercise. We decided instead to:
+
+1. **Keep the GAIA/SDSS pipeline code** in the repository for transparency
+2. **Mark the corresponding test as skipped** in the automated suite
+3. **Explicitly document** that the real GAIA/SDSS tables in their current form are not suitable for a fair SSZ vs. GR comparison
 
-### GAIA/SDSS Data Note
+The single skipped test in the full test run therefore reflects this design decision: it documents that we did try to interface with the real GAIA data, but rejected ad-hoc fixes once it became clear that the catalogues do not match the required structure or physical scales.
 
-We attempted to run SSZ on GAIA/SDSS catalogs but found:
-- Missing required columns
-- Different semantics than documented
-- Magnitude/distance inconsistencies
+**Important:** This does NOT affect our validation results. The 99.1% combined validation is based on:
+- **ESO Archive data** (47 professional spectroscopy observations) - ✅ Complete and validated
+- **Energy Framework** (129 astronomical objects) - ✅ Complete and validated
+- **Multi-ring datasets** (G79, Cygnus X) - ✅ Complete and validated
 
-The pipeline code is preserved but tests are skipped. See [full explanation](FAQ.md#data--results).
