EXOCHAIN HardShell

HardShell is the environment + operations layer for EXOCHAIN: reproducible dev/test/staging scaffolding, controlled run wrappers, and evidence bundles (hashes, logs, configs) suitable for audits.

Design principles

• Lean + clean: minimal host assumptions; reproducible toolchains.
• Slow is smooth: we prefer explicit checklists and deterministic builds.
• Two is one: caching + fallbacks; evidence-by-default.

Local layout

• environments/ — environment-specific configs (dev/test/staging)
• scripts/ — build/run/evidence scripts
• evidence/ — exported evidence bundles (gitignored by default)

Today’s scope

• Build EXOCHAIN from source locally (inside our current container)
• Define conventions so we can later migrate to GitHub Actions + org repos cleanly
