A browser-based companion for SeedHammer v1 hardware. Three coordinated PWAs (composer, emulator, combined-sim) plus an optional Android wrapper, inspired by Gangleri42's SeedHammer II fork but retargeted to v1's Pi-Zero / WaveShare / MarkingWay hardware. What's in this commit: - LICENSE: Unlicense (matching upstream) - README.md: project overview + status + roadmap - CREDITS.md: upstream provenance + pinned baseline SHAs - docs/architecture/: five authoritative design docs (lifted from the prep work in mineracks-infrastructure): * BASELINES.md — pinned SHAs, license audit, path-mapping table * v1-engrave-spec.md — MarkingWay USB-serial wire protocol audit * v1-buttons-and-ui.md — GPIO map, UI screen flow, keyboard map * sh1e-spec.md — composer-to-Pi envelope format spec * seedsigner-reuse.md — Pyodide strategy + jumbo (SeedSigner+) support - Go package skeleton with doc.go contracts: backup, bezier, bspline, engrave, engrave/wire, engrave/wire/sh1e, font (+ comfortaa, poppins, constant), gui, input, internal/golden, platform/v1 - cmd/ entrypoints with stub main(): composer, emulator, combined-sim, seedsigner-sim - web/ static-shell skeleton - go.mod (module github.com/mineracks/seedhammer-v1-companion, Go 1.22) - go build ./... + go vet ./... both clean Next: lift universal packages (backup, font, bezier, bspline) from upstream seedhammer/seedhammer at v1.3.0 verbatim.

// Package backup defines SeedHammer v1 plate dimensions and layout

// constants.
|
||
//
|
||
// Three plate types are supported, matching upstream's stainless plate SKUs:
|
||
//
|
||
// SmallPlate 85 × 55 mm — single seed (12 or 24 words)
|
||
// SquarePlate 85 × 85 mm — single seed + title
|
||
// LargePlate 85 × 134 mm — seed + descriptor for multisig
|
||
//
|
||
// The engraver's origin sits 97mm in the X axis from the plate edge (a
|
||
// fixed offset of the physical machine). outerMargin = 3 mm and
|
||
// innerMargin = 10 mm define the engrave-safe area.
|
||
//
|
||
// All constants are mm; the engrave/ package converts to machine steps
|
||
// (1 step ≈ 0.00796 mm) at command-generation time.
|
||
//
|
||
// Status: STUB — to be lifted verbatim from upstream's backup/backup.go
|
||
// at v1.3.0. The constants are stable across all v1.x releases.
