Phase 3 — Community testing + reproducibility

[Zyrtnin]

Blocks on #1 (Glyph) and #2 (P2PKH hardening) being substantially complete. This is the multi-device, multi-firmware, multi-tester validation that turns "Eric's device works" into "any Nano S Plus holder's device works."

Recruit testers

• Post the Discord announcement (draft exists in conversation history)
• Recruit 3–5 testers from Radiant community — different Nano S Plus firmware versions ideally
• Provide each: INSTALL.md, release bin/app.hex, published SHA256, loadApp command

Reproducibility validation

• ≥1 non-author tester runs the reproducible build on their own machine, confirms sha256sum bin/app.hex matches the release SHA256. If it doesn't, reproducibility is broken — halt release, diagnose.
• Collect each tester's build environment details (host OS, Docker version, arch) for a "known-good environment" note

Firmware coverage

• Record each tester's Nano S Plus firmware version
• Collect ≥2 distinct versions (current + previous)

Host-OS coverage

• Linux primary (Eric's dev setup is Ubuntu 24.04 + Python 3.12)
• macOS primary (coverage goal for v1.0)
• Windows best-effort only — Zadig/WinUSB landscape is a v1.1 problem; accept tester reports but don't block release

Test matrix (assigned per tester)

Tester	Firmware	Tx shape	OS	Reproducibility check
#1 (lead dev)	current	1-in/1-out	Linux	Yes
#2	current	1-in/2-out (change)	Linux or macOS	Yes
#3	previous	5-in/2-out	any	No
#4	any	coinbase input	any	No
#5	any	Glyph mint (commit + reveal)	any	No

Release gate

• All testers' txids confirmed on mainnet
• ≥1 independent reproducibility match
• Zero reports of stuck funds, wrong-network signing, or signing of unintended addresses
• Test matrix results published in README
