The operator caught what no check had ever tested: nobody had LOOKED at
the rendered pages. A ten-inspector visual audit of all 129 pages (every
page opened as an image) found 40 defects, including didactic
correctness bugs invisible to the text layer:
BAD, fixed:
- ch03 printed WRONG Lean operators: \lean{P /\ Q} lost its backslash
('P / Q') and \lean{P \/ Q} lost the operator entirely ('P Q') —
TeX ate them inside the non-verbatim macro. Now the unicode ∧/∨ the
book uses everywhere else.
- ch12: the doubling display overflowed its box border, slicing the
math; stacked on two lines.
- toolkit Card 6: the headroom-audit display was clipped by the page
edge; now an align* stack.
UGLY, fixed:
- title page: the 'pyramid motif' at 5% white opacity on near-black
rendered as smudge artifacts, plus a clipped ∀ glyph in the corner
— redrawn with solid mixed colors (no transparency), glyph removed;
the footer's mid-word paragraph gap was a \vspace landing inside
horizontal mode; fixed with \par
- ch06: both clock diagrams' wrap-around arrows ran counterclockwise,
retracing over earlier arcs — target position expressed as 12 (one
revolution) so the arc continues clockwise, landing on 0 (mod 12)
and 1 (mod 11) correctly
- ch04: two_mul'' printed as two_mul" (quote ligature)
- one-line orphaned box fragments and stranded solution headings
throughout: bigidea/tryit/pitfall/aha/checkpoint are now unbreakable
(none exceeds half a page), worked boxes announce '(continued)' after
a break, \solhead keeps four lines with \Needspace
- --all/--receipt flags printed as one merged dash: \ddash macro
- inline code no longer hyphen-breaks at underscores (codeguards)
- ch09's 2^{...} smudge, glossary margin overflow, ch08 orphaned
listing line, ch13 command-line layout, three >10pt overfulls
THE STRUCTURAL LESSON, encoded: the two worst clipping bugs had been
announced as 80pt/73pt overfull warnings in every build log and ignored.
check-book.sh now FAILS on any overfull box past 10pt — the machine was
telling us; now it is allowed to stop us.
132 pages; publication-history and README counts synced; every fixed
page re-rendered and verified by eye. Button: ALL GREEN (96 checks).

New Chapter 13, 'The Second Summit: A Hash-Based Pyramid' — SLH-DSA
(FIPS 205) as the transfer experiment for the whole method:
- opens on leaf 18 as the anomaly; correctness-vs-security across the
quantum divide ('a correct implementation of a broken lock is still a
broken lock')
- Lamport -> Winternitz chains with the checksum see-saw run twice on
real w=16 numbers, including a concrete failed forgery (480 -> 479,
digit 14 -> 13)
- FORS worked at napkin scale (k=2, a=2, one reuse = one forgery) and
real scale (28 of 57,344, exponent 14)
- the virtual hypertree: digest split 21/7/2 to the bit, the 54-bit
meter peeled 9 bits per layer, verification priced exactly (254 fixed
oracle calls; the see-saw itself caps a layer at 510, so worst case
3,824 — the naive 525*35 bound is unreachable, and the chapter says
why); ~2^72 to build vs ~2^12 to check
- the eleven certificates, the loop-to-fold bridges, the honest
'visible, not correct' boundary (no second semantics — and why the
natural move fails), the cone-growth table, the t_l/t_len naming
inversion told as the war story it was, the apex as an audit
invitation with the verbatim theorem named
- 'The leaf, live': leaf-vs-head precision ('plausible, and wrong
twice'), the three-clause self-reference ledger (attested machinery /
attested scheme / honest gap), one-command tryit
- six exercises with pathway'd solutions; checkpoint hands the
who-checks-them question to the finale
Structural: attestation renamed ch14 and now carries the book's single
ending (where-to-go, further reading, final reframe, prospective
checkpoint — moved from ch12); its two interior checkpoints demoted to
bigidea/tryit so the terminal checkpoint stands alone; opening now
receives ch13's baton. ch12 ends as a chapter. Front matter: three-summit
arc, fourteen-week plan, honest discussion-exercise count; ch01 promise
ladder extended to Chapters 13/14; glossary +5 entries (and the
pre-existing Hasse-bound misordering fixed); README fourteen chapters +
build.sh recipe.
Every constant verified against fips205-slhdsa-verified and
lean-transparency-log by four adversarial checkers; arithmetic
independently recomputed; didactic panel scored the chapter 9/8 —
the book's high-water mark. Build: 128 pages, zero unresolved refs.
