This applies every MUST, SHOULD and NIT from the fourth audit (plain language, non-repetition, and consistency within the text and against the programs and figures). Each chapter group's edits were re-checked by an independent pass against the companion code.

Merge quicknode/solana-program-examples' claude/wonderful-hawking-5gg014-audit4 PR first. These chapters describe its changes. Squash-merge recommended: the branch's commits are work-in-progress snapshots.

Following the program changes

• Options: writers' accounts are created as needed, and buy_option() checks the terms.
• Lending: interest rounds up.
• Managed fund: the Pyth verification check, the deposit valuation rounding up, and the math heading.
• Perps: PnL, funding and pool shares round against the user.
• Prop AMM: close_market() is in the prose, the tests, and all six handler-list figures.

Claims narrowed or cut, because the programs don't support them

• The fundraiser's "any mint works" footnote.
• The betting market's cancel_event() exit, in the Offchain Truth chapter.
• The perps exit-rule claim.
• Prop AMM counterparty choice and size ladders, now credited to real venues.

Other

• Many plain-language, repetition and glossary fixes.
• "Fronts the rent" vs "pays the rent" is now right in every figure.
• A paragraph that Paged.js clipped in the paperback (Tokens) is fixed.

Print

PRINT-SPECIFICATION.md now has:

• 315 pages digital, 313 paperback interior, 273 Letter;
• a 0.705in spine and a 15.835 x 9.94in wrap.

The cover art implies a 0.690in spine, so re-export the Figma frame at 313 pages for production.

Checks

• npm run lint: clean.
• node scripts/check-figure-geometry.mjs: clean across 115 figures.
• build-pdf-digital, build-pdf-paperback and the Letter build: all succeed, with no clipped text.
