ISH-D Column D base ten.
The right column groups 11, 21, 19 and 9. These are 10+1, 20+1, 20-1 and 10-1. Their sum is 60.Referencing norms: OffsetEleven, OffsetNine, OffsetNineteen, OffsetTwentyOne, RightCanonicalSum

ISH-G Column G primes.
The left column of the Ishango bone groups 11, 13, 17 and 19 notches. These are the primes between 10 and 20. Their sum is 60.Referencing norms: PrimeColumnCanonical, PrimeColumnSum, PrimeOnOpenDecade

ISH-M Column M doubling and halving.
The middle column groups 3 then 6, 4 then 8, 10 then 5, and 5 then 7. Adjacent pairs witness doubling (3 to 6, 4 to 8) or halving (10 to 5). The remaining pair 5 and 7 sums to 12. The column sums to 48.Referencing norms: DoublingAdjacent, HalvingAdjacent, MiddleCanonicalSum, PairTwelve

ISH-T Global balance and Marshack total.
The left and right columns both sum to 60. The three columns together sum to 168. Marshack reads 168 marks as about 5.7 synodic months.Referencing norms: ColumnBalance, ColumnsBalanced, MarshackHalfYear, MidMultipleOfTwelve, MidTwelve, Total168, TotalMarks168

LEB-1 Sequential ledger.
The Lebombo bone is a baboon fibula from Border Cave (Lebombo Mountains). It bears 29 distinct notches cut successively. Each later notch presupposes the previous: the register is append-only and admits no gap in the index.Referencing norms: NoGap

LEB-2 Lunar cycle of 29.
The 29 notches correspond to a synodic month. Day 1 or 2 is new moon. Day 7 or 8 is first quarter. Day 14 or 15 is full moon. Day 21 or 22 is last quarter. Day 29 completes the cycle.Referencing norms: CycleByLength, CycleCompleted, StationFirstQuarter, StationFullMoon, StationLastQuarter, StationNewMoon

LEB-3 Overflow beyond 29.
A thirtieth notch on the same register without opening a new register exceeds the cycle. The overflow is a constraint, not a silent wrap-around.Referencing norms: CycleOverflow
The hash beside the text is the sha256 of its exact bytes. It is the check that the text shown matches the one pinned in the package: a divergence fails the oracle’s static analysis.
