Have we ever run step 1 without P₂O₅?21 Aug 02:51
I now have the full picture. Here's the answer.
Answer: No confirmed step-1 run without P₂O₅ is on record. Across the whole experiment set (Batches 1–69 plus the stub samples), every step-1 record that exists mentions P₂O₅ (or PPA → P₂O₅): Batches 1, 5, 7, 13, 25 A/B/II, 34 B, 36, 37 A, 38 C, 39, 40, 48, 48 Q, 54 A, 55, and the unlinked "notebook p19, step-1" fragment. No record in this data drop has a step-1 description omitting P₂O₅.
One suggestive sample exists: NO-P-76 — six NMR plots dated 30 SEP 25 (1H/13C FS and zoom1/zoom2). The alias "NO-P" is consistent with a "no P" / no-phosphorus control, but this is a STUB: it is an unlinked sample, not a confirmed experiment. Its record has no materials, no process steps, no date, no outcome, and
Gaps: no batch number or process recipe is linked to NO-P-76; the meaning of the "NO-P" alias is unconfirmed in the drop.

context/30-entity-links.md explicitly notes "which batch made it is unknown." Nothing in the documents explains what "NO-P" denotes, so I can't confirm from the records that it was a step-1 run without P₂O₅.Gaps: no batch number or process recipe is linked to NO-P-76; the meaning of the "NO-P" alias is unconfirmed in the drop.
