What

Text-only corrections in paper/Sections/{model,intro,static,conclusion}.tex; no code or artifact changes.

  1. £100k dominated width. model.tex said raising the threshold to £100,000 "relocates the region without altering its width: it is the same £21,250 band, transported to the new cutoff". The paper's own formula gives a = 100,000 × 0.20/0.80 = £25,000, so the region becomes (£100k, £125k); only the proportional width a/T* = 25% is unchanged. Corrected here and in the three places that repeat "relocates" (intro finding 2, the static relocation paragraph, the conclusion).
  2. Band counts. The reduced-rate primary/secondary counts in model.tex (111,900 / 77,300; 34,200 / 65,500; totals 146,100 / 142,900 "within 3.3%" of a 147,700 baseline) do not match results/dominated_region_mass.txt (130,991 / 88,767; 26,682 / 52,517; totals 157,674 / 141,284 against 156,747). The same section quoted both 157,000 and 147,700 for the baseline band. Replaced with the checked values (rounded to hundreds); the baseline band is now quoted once as 156,700 in that paragraph, while the "about 157,000" rounding elsewhere (intro, Section 6 opening, summary table) is consistent with it and left as is.
  3. £21,562£21,563 (exact value 21,562.50).

Why now

These are algebra and internal-consistency fixes that hold regardless of the #37 regeneration. The counts will be re-synced again when the population is regenerated; the ESS/max-weight numbers in data.tex are deliberately left for that pass (#40) to avoid re-numbering twice.

Checks

  • Each replaced string matched exactly once in its file.
  • The Paper workflow renders on paper/** PRs; no new macros or references introduced.

…with the checked artifact

The width a = T*·tau/(1-tau) is proportional to the threshold, so raising
T* to £100,000 widens the dominated region to £25,000 (£100k–£125k); the
text said the £21,250 band was "transported" unchanged. Cascade the
correction to the intro, static section and conclusion.

Replace the reduced-rate primary/secondary band counts, which came from an
older run, with the values in results/dominated_region_mass.txt, and use
one baseline count (156,700) instead of 157,000 and 147,700 in the same
section. Round £21,562.50 to £21,563.
