Final text preflight: C931 synthesis and companion

Disposition: PASS after the three C923 wording corrections. No unresolved material numerical error, overclaim, or source-scope issue remains in the reviewed text. Numerical models require no repair.

Review performed

Read the integrated synthesis and technical companion in full. Compared the principal claims with the current complete-field models, the frozen C831 synthesis, and relevant frozen File43, File58 and File63 source passages. Read the claim map and C918 reconciliation. All six independent-domain JSON records match the hashes recorded there; their170 checks are inherited review coverage, not170 additional checks performed by this preflight.

The semantic pass also covered the reading guide and the exact SVG text. Their family labels, operation examples and limits agree with the corrected prose. The P/J order witness is explicitly a diagnostic, the restored NT/MT edge measures remain70|70 versus35|130, and the map retains the distinction between equal total and equal interior. This review does not claim a new raster-layout inspection.

Corrections resolved at C923

1. The companion now correctly calls897Z and4485Z the intersections of the Keys’ input self-domains. They are not intersections of the output images. The individual domain generators and frozen numerical model were already correct.
2. The inherited SP/LXX cumulative field explicitly retains official SP Terah145 and excludes substitution of the separate Ideal205 cumulative lift. This protects the difference between full birth alignment and a particular cumulative realization.
3. The two decimal exceptions are now called trailing-zero cases, correctly distinguishing Adam/Jacob from zero-duration inputs.

Mathematical and source-role assessment

The full festival walks and their0/59/140/199 common prefixes agree with the model. Category margins preserve the stated totals without equating sex and purity or recovering species counts. The NT78-row display and its primary77-slot extent keep name, interval, carrier and figurative-bookend counts distinct. The49/70 common grid is derived from the supplied measures, while named BJ placements remain source premises.

The decimal formulas retain one pass per original input, placeholder zeros, and the32-row/64-endpoint manifest. Core digits and length are explicitly computed operational state under the fixed policy. The branch formulas agree with the frozen whole-field classifications, and no second inversion or expanded target search is claimed.

The grid theorem assumes an input already on the declared hZ grid; the reduced denominator determines the admissible input subgroup. The staged-prefix theorem and anchored-order formula address different issues. The File46 fractional head images remain exact rational outputs; failure of simultaneous integrality is not represented as arithmetic failure.

All six macro heads preserve their source and target roles. The2081/2051 pair remains author-designated/proposed,1936 remains the source whole-year cumulative boundary, and the large heads remain generated. The retained147 biography is distinguished from the uniformly transformed3430/23 interval. The shared12026 weighted coordinate retains different9890/9900 spans and does not collapse Actual/Rounded pairs.

The inherited MT rounding and BJ575 comparisons retain their original source tensions rather than silently repairing them. Latest File52c remains controlling. The text preserves the current Gear scope, deferred second inversion, and quarantined primers. It does not claim unique minimality, independent-success statistics, historical transmission, or theological causation from these reconstructions.

Boundary of this preflight

No numbered action, root deliverable, immutable packet, canonical source, or journal record was changed by the reviewer. Only this review and its JSON companion were written. Final portable prefix replay, cycle closure, packaging and saving remain separate operations for the root.
