SeedHammer II manualfirmware v1.4.3 · llms.txt

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).
