Measured before writing: the book made ZERO references to the transparency
log, the live site, leaves, receipts, verify.py, or anything post-quantum —
two incidental uses of the word "accumulator" were the entire overlap with
the estate's flagship artifact. A book that teaches "who checks the checker"
never mentioned that a live log practicing every one of its principles is
publicly checkable.
New closing section of ch13, "Go and touch the real thing": what a leaf is in
the chapter's own vocabulary; the fifteen-minute exercise (clone the mirror,
verify.py --all, pin both trust anchors two independent ways, read leaf 18 in
full); the map from the log's nineteen leaves onto the book's chapters
(leaves 13-16 = the pyramid at 44 certificates with ch11's boundary-exact
apex cones in production; leaf 17 = ch13 made literal, the log carrying
proofs of its own Merkle machinery; leaf 18 = the first post-quantum subject,
FIPS 205 verify path); and the two boundaries a reader must hold — verify
proven / signing never, for both algorithms, and the frozen paper as an
honestly-aged snapshot contained byte-identical inside today's history.
Root cause of the staleness, named: the book has no button. Every other doc
surface in the estate is gated or audited; the book froze as a July-6
deliverable plus one chapter. Until it grows a gate, estate doc audits are
its only clock (last: 2026-08-08).
README: ch13 entry expanded accordingly. PDF still awaits a LaTeX host.

The book taught act one (getting a kernel to accept a proof) across twelve
chapters and never taught act two: the protocol that makes a green light mean
something to someone who was not present. ch11 armed the reader to interrogate a
CERTIFICATE and left the script that interrogates certificates — software the
author wrote, verified by nothing — entirely unexamined. That was the gap eight
rounds of external review found in the companion projects, and it is a didactic
failure of this book too.
ch13 teaches it from the war stories: the two acts and why act one is the easy
one (eleven theorems in two days, never disputed; eight review rounds and
eighteen defect classes to make the button over them credible); the single shape
every failure had (something load-bearing sat outside the binding), with the
demonstrated exploits including ALL GREEN over a repository proving False, a
certificate reduced to 'the loop equals the loop' with every fingerprint
byte-identical, and a stubbed compiler wrapper going green in 3.6 seconds over
destroyed proofs; completeness of binding and its four rules (derive the
population, fail closed on absence, exact not subset, a stranger must re-derive);
and the meta-defect of assertions that pass for the wrong reason, including the
tautological assert that appeared twice — the second time inside its own repair.
Closes with the habit to carry: ask both questions, and invite someone to attack
your button early, because none of the eighteen was found by the author.
ch11 now forward-references it at the point where the old blind spot sat.
