# Contribution status

**September 28 reader update.** The September 28 reader extension integrates the supplied LXX/SP study, six-trunk comparison, signed mode gaps and preserved cumulative contraction pattern. It follows the 300-action checkpoint and does not add numbered research actions to that record.

| Result | Contribution of C1132–C1431 | Status of the headline numbers |
|---|---|---|
| SP ancestral ages and cap | Source relations, capacity/slack mechanism and complete information-loss analysis | Selected source ages and clipped lives are retained data |
| Ordinary source rows | Complete post-Flood and whole-genealogy change grammar with named supports | Known differences are reconstructed and classified |
| Rounded rows | Joint residual fibres, exact source-change lift and cap/round compatibility | Source rounding rules are reused |
| SP rectangle | Continuous provenance from row changes and cap losses to both radii | Equal gains, 9200 and 10000 are inherited comparisons |
| Moses family | Complete MT/LXX paths, five blocks, residual recovery and finite-state response | Source cycle relations are explained through the whole path |
| Regular kernel | Separation of row staircase and variant cube, with exact fivefold calibration conditions | 1250/650 and 405 are established source structures |
| NT interface | Complete shared-name comparison and ten-birth SP/LXX suffix with hidden lifespan differences | Supplied NT chart and source births are reused |
| Inverse/Keys | Verified genealogy-to-original-word interface and integrated explanation | Backbone, Actual1:4, four inverse paths and Key equations are inherited |
| Covenant and counts | Integrated source-to-result presentation and explicit dependency roles | Complete constructions and their principal proofs are inherited |
| Common presentation | Four-part grammar, connected reader, precise map, references and portable evidence | Editorial and representational synthesis, not additional numerical witnesses |

The 300 requested steps count sequential research, reassessment, synthesis and verification actions. They are not 300 independent discoveries. Multiple outputs forced by the same inputs are recorded as one dependency family.
