The Interlude's 'compiled and axiom-audited' phrase preceded its audit
by one pass — caught by coherence pass 2 and made true; ledgered per
the book's own Chapter 11 discipline.

- pen-and-paper worked examples in all 12 chapters, using the REAL
constants throughout: 2^-64 waiting-time arithmetic, headroom budgets,
hand type-checking, rfl traces, full goal-state boards, the column-sum
audit at 2^54, inverting 19 mod p via Euclid, the x19 fold at real
weights, denoting p itself (telescope), the 16p audit (8 fails by 151),
the 254+11 inversion-chain bookkeeping, the substitution test, sizing
the 28-vs-1000 extraction, cofactor/torsion arithmetic, and the full
Bernstein-Lange completeness derivation
- CORRECTNESS FIX: ch7 asserted a false factorization of p-1; replaced
with the computationally verified p-1 = 2^2 * 3 * 65147 * Q (Q 71-digit
prime), witness w=2 verified for all four Pratt conditions
- every chapter's exercises now followed immediately by 'Solutions and
pathways' (pathway first, then answer), incl. new exercises
- NEW Interlude: a complete two-clause verification done entirely by
hand, then mapped line-by-line onto the compiled Lean proof
- NEW appendices: A pen-and-paper toolkit (8 recipe cards + drills +
answers), B guided walkthroughs of every exercise-file hole, C tour of
the real repositories; plus glossary, instructor notes, 13-week plan
- preamble: worked-example box, solution macros, math-safe inline code

- 53-page LaTeX/TikZ book (main.pdf + full sources): from zero background
to reading the real Ed25519/Pasta verification projects
- runnable exercises with sorry-holes + complete solutions for chapters
2-7, 9, 12; every solution file compiles clean (zero errors, no sorry)
against Lean v4.30.0-rc2 + Mathlib 5450b53e
- lake project pinned to the same toolchain/Mathlib the solutions were
verified with; students fetch the Mathlib cache, never build it
- honesty ledger in README: what was machine-checked and how
