Step 2 A.V. cell holds prose 'Iodine value' with no numeric value — emitted as an unlabelled measurement with confidence medium; treat as a stray extra (parameter name only, no result value). Step 2 Temp/Time read as a single stage '74-81 oC for 2 h' (no multi-line ramp present). Step 3 material list: 'Step - 1 Product' qty '0.8' and 'Phosphate' qty blank — quantity for 'Step - 1 Product' is suspiciously small for a Step-1 reaction mass (350 g charge in Step 1); kept verbatim with low confidence, flagged for cross-check against ELN. 'Phosphate' quantity column is empty in the printed block. Remarks column spans the whole experiment and reports pigment resolubility tests for Violet-23 and Black both failed."
