Lift composer substrate from upstream v1.3.0
...
Twelve packages lifted from seedhammer/seedhammer @ v1.3.0
(commit 2f071c1d8f23eb7fd39b15fc0acb8874113f801e):
address/ — bitcoin address parsing
backup/ — v1 plate dimensions + UR-coded multi-plate backup
bc/ — Blockchain Commons: ur, fountain, bytewords, urtypes,
xoshiro256 (5 subpkgs)
bip32/ — HD-key derivation
bip39/ — mnemonic seed phrases + 2048-word wordlist
engrave/ — text/QR → MoveTo/LineTo command stream conversion
seedqr/ — SeedQR / CompactSeedQR encoders
image/ — paletted, rgb565, alpha4, ninepatch image formats
nonstandard/ — bitcoin descriptor + script parsing
font/ — bitmap + vector font runtime
font/{comfortaa,poppins,constant,bitmap,vector}/ — actual fonts
driver/mjolnir/ — MarkingWay USB-serial engraver driver
Plus an earlier-aside backup_test.go restored (its deps are now lifted).
Import paths globally rewritten seedhammer.com → mineracks namespace
via single sed pass; verified no orphan refs remain. go.mod adopts
upstream's full dep set plus the replace-directive for the patched
kortschak/qr fork.
go build ./... clean (all 27 packages)
go test ./... clean (12 packages with tests, all passing)
NOT lifted in this commit:
- driver/{wshat,drm,libcamera} (hardware-specific GPIO/LCD/camera —
will be platform-v1/-shaped abstractions instead)
- gui/ (depends on the above; lifts in Phase 2)
- cmd/{controller,...} (Pi binary entrypoints — not needed for the
companion repo)
- zbar/ (QR scanner — needs libcamera)
Next:
- Write the SH1E reference encoder/decoder in engrave/wire/sh1e/
- Lift Gangleri42's cmd/webnfc/ shell + retune to v1 plates
- First buildable composer WASM with a working preview

Lift bezier/ + bspline/ from Gangleri42 fork
...
First batch of code lifts: hardware-agnostic curve math packages.
- bezier/: cubic + quadratic Bezier curve representation +
tessellation. Lifted verbatim from Gangleri42/seedhammer
@ 0a3c63ef path bezier/. Stdlib only.
- bspline/: B-spline curves + an LP-based optimiser that finds the
smallest engrave-stroke representation of a path. Lifted from
Gangleri42/seedhammer @ 0a3c63ef path bspline/. Depends on
bezier/ + gonum (BSD-3, brought in transitively).
Import paths rewritten from `seedhammer.com/X` to
`github.com/mineracks/seedhammer-v1-companion/X`. No other changes.
go build ./... and go test ./bezier/... ./bspline/... both clean.
Doc.go stubs updated to reflect LIFTED status with the source
commit pinned.
Deferred to next commit:
- backup/ (needs bc/fountain + bc/ur transitively for UR codes)
- font/{comfortaa,poppins,constant}/ (needs font/bitmap runtime)

Initial skeleton — Phase 1 scaffolding
...
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.
