# HARMONIZE-wave1

# Wave 1 harmonization

Done 2026-10-10 over the 13 wave-1 pages, from manuals/REVIEW-wave1.md sections 1 to 4. The three descriptor-* pages
were not edited. Line numbers are those of the page before this pass, as in the review (cat -n). Quotes are shortened
with "..." where the cell would otherwise run long. Rules applied throughout: no em-dashes, no names, no chat quotes,
exact firmware strings, and the new STYLE.md Vocabulary rule (the machine engraves; jobs are restarted or resumed).

## Single statements and where they live

| 14 Passphrase and seed-to-descriptor check | Nothing compares a seed with a descriptor in the source; Check: on a machine | multisig-and-fit#descriptor | SYNTHESIS F1, F2 |
| 15 Status line position | "for about one second"; Check: where it sits | power-and-first-start#start-screen | device-screen-map 1.2 ("above the version") disagrees with the code reading (bottom centre) |
| 16 What v1.4.1 and v1.4.2 left out of the QR | The master fingerprints and the origin paths before each key; like v1.4.3, no checksum | multisig-and-fit#differences | v1.4.3 release note "The checksum is still stripped" (research/hardware-signers.md section 4) |

Measured after the pass (120-column wrap of front matter and visible text, capture comments and the maintenance block
left out; this count equals or exceeds the review's by one line): every how-to page is at or under 140 lines (power 139,
nfc 139, seed-entry 140, firmware-upgrade 140, multisig 137, recovery 140, hardware 138, plates 122, engraving-quality
140, titles 140). The longer pages are capability sheet 279, troubleshooting 245 and security FAQ 264, now mostly tables
and short paragraphs.

## Decided, not changed

- Line wrapping: the upstream firmware-upgrade.md (fetched from website-content 2026-10-10) puts each bullet or
  paragraph on one line and has no line over 106 characters, so it settles neither style. The pages keep their
  current wrapping. Upstream also uses the title "Firmware Upgrade", so that title stays.
- The silkscreen text "NFC CUT HERE" on security-faq is quoted as printed on the board; every prose use of the word
  was replaced.
- The capability-sheet wallet table stays: descriptor-mobile-wallets links to capability-sheet#wallets.
- Terminology for the right-edge controls ("tab", "touch buttons", "touch slots") and the machine's name ("SH II"
  or "SeedHammer II") was not unified; "company", "controller board" and "engraving solenoid plug" were.
