| 2026-11-01 | Developing → Secure | adjudicated paper #10 Q10: 3/3, why:stretch, developing → secure — three 8-bit numbers added in columns, correct, unaided, 2 min, inside a timed section. Second independent occasion at the secure bar: 16 Oct handwritten two-number sum with carries 1/1 unaided. Overflow sentence 2/2 cold on 19 Oct. One level. | standalone |
| 2026-10-21 | Developing → Developing | paper #10 Q10: 3/3, loss=none — three 8-bit numbers added in columns, correct, 2 min | session 127 |
| 2026-10-20 | Developing → Developing | 19 Oct cold, first item, typed: extra digit is lost and the stored answer is too small. Name, mechanism and effect in one unaided sentence, 2/2 (16 Oct 1/2). With the 16 Oct handwritten sum, proposed secure for adjudication. | session 117 |
| 2026-10-16 | Developing → Developing | Correction to the 16 Oct line: the status is developing, not secure - 'stays secure' there should read 'stays developing'. The handwritten sum (1/1 unaided) is the first of the two unaided occasions secure needs; the overflow sentence at 1/2 is the other half still owed. | standalone |
| 2026-10-16 | Developing → Developing | Session 114, 16 Oct, by hand in pen, photo 13:16 (set 13:12, agreed 13:19): 10110111 + 01101101 -> 00100100 with carry marks, eight bits right, unaided - the sum owed since 2 Oct is done. Overflow: open -> 'an error and it won't compute' (0/2); 'right or wrong' -> wrong; 'kept or lost' -> 'it gets lost'; own sentence 'called overflow... extra diget and the diget gets lost' 1/2, effect on the answer not added when invited. Sum at the bar; sentence not. Stays secure. Retrieval: retry. | standalone |
| 2026-10-01 | Developing → Developing | 1 Oct starter, no notes: 01101110 + 00110111 → 10100101, six carries named by column (2, 4, 8, 16, 32, 64), checked as 165 in decimal unprompted. 1/1 unaided, typed; asked to work on paper, no photo seen. Overflow sentence not asked. | session 61 |
| 2026-09-29 | Not started → Developing | Correction (parent rule, 29 Sep): a topic taught and answered cannot stay notstarted — right → developing, wrong → gap. Session 58, 29 Sep: binary addition taught, carry rule in her own words; 45+22 → 01000011 and 103+93 → 11000100 with all seven carries named, 2/2 unaided. notstarted → developing, one level. | standalone |
| 2026-09-29 | Not started → Not started | 29 Sep: four addition rules taught; carry explained in her own words; 45+22 → 01000011 alone (no carry row shown), 103+93 → 11000100 with all seven carries named alone, 2/2. Overflow: named the idea ('the max number we can put'), term supplied by the tutor. Proposed developing; not moved — two items only, no independent exit item and overflow not yet produced by her. | session 58 |
