Summary

Three small fixes to the entry-point documents flagged in a fresh review of README.md and cascade-series-cover-sheet.tex:

  • README headline H₀ row: show Gram-corrected ≈67.5 km/s/Mpc instead of the leading-order 66.78 (which sits ~1.24σ below Planck's central, outside the 1σ band — the "Planck-compatible" label was loose at that value).
  • README headline table: add T_CMB row (2.642 K, −3.1%, descent-dependent). Previously omitted from the headline table while smaller deviations were shown under a "closed within experimental error" header — selection-bias presentational issue.
  • PREDICTIONS.md Tier 1: add a "No axion" row (θ_QCD = 0 topologically, IVa) to match prose claims in README and cover sheet that already list it among structural exclusions.

src/generated/predictions-table.tex and web/index.html regenerated from PREDICTIONS.md via tools/generators/generate_predictions.py. The new no-axion row now appears in the cover sheet's Tier 1 table and on the project website.

Out of scope (flagged but not edited)

The cover sheet's Hypothesis section (lines 113–115 of src/cascade-series-cover-sheet.tex) still carries retracted wording — "a Hubble constant between the two competing measurements" and "an account of the DESI baryon acoustic oscillation observations without dynamical dark energy" — that contradicts the same document's Series summary (lines 247–252) and the position recorded in CLAUDE.md. Worth a follow-up PR.

Test plan

  • python3 tools/generators/generate_predictions.py runs cleanly (5 tiers, 39 predictions parsed).
  • Verified "No axion" row appears in src/generated/predictions-table.tex Tier 1 between "No extra Higgs bosons" and "No gravitons".
  • Verified web/index.html injection picked up the new row.
  • Local LaTeX build of cascade-series-cover-sheet.tex to confirm the regenerated table still typesets cleanly (CI will cover this).
  • Visual check of the rendered website Predictions table.

- README headline numerics: show Gram-corrected H₀ ≈67.5 km/s/Mpc
  (was 66.78, leading order, ~1.24σ below Planck central) and add
  T_CMB row (2.642 K, −3.1%, descent-dependent) so the table
  reflects the largest descent-dependent deviation rather than
  omitting it under a "closed within experimental error" header.
- PREDICTIONS.md Tier 1: add "No axion" row matching the prose
  claim in README/cover sheet (θ_QCD = 0 topologically, IVa).
- Regenerate src/generated/predictions-table.tex and web/index.html
  from PREDICTIONS.md via tools/generators/generate_predictions.py.
PREDICTIONS.md Tier 2:
- H₀: predicted column now shows "66.78 km/s/Mpc (Gram-corrected ≈ 67.5)"
  and the dev column reads "−0.9% leading; ≈Planck after Gram", so the
  cover sheet's table carries the same Gram-corrected representation as
  the README headline rather than only the bare leading-order number.
- T_CMB: dev column annotated "(descent-dependent)" to match README.

src/generated/predictions-table.tex and web/index.html regenerated.
