Coordinate the HSSM ecosystem

HSSMSpine is the contributor front door for coordinated development across the HSSM ecosystem. It tells you which repository owns a change, starts coding agents with the right cross-repository context, and records shared contracts and maintenance procedures. It contains no importable library package.

Choose your path

• New contributor: follow the first ecosystem task, then learn how the development environment is arranged.
• Working on a change: select a task context, inspect workspace health, and create a worktree when parallel branches require one.
• Maintaining the ecosystem: use the release procedure, review freshness drift, and understand scheduled maintenance.
• Looking up a contract: start with commands, repository roles, or source ownership. The documentation platform and architecture decisions record shared contracts.

What Spine owns

Spine owns cross-repository coordination surfaces: the documentation platform contract, shared agent context, capability recipes, and procedures that span package boundaries. HSSM hosts the canonical public ecosystem map while Spine's source repository remains private. Package behavior, public APIs, tests, releases, and package-specific documentation remain owned by the corresponding package repository.

That boundary is the organizing principle for this site. The dependency flow explains how packages and artifacts connect; source ownership tells you where a durable change belongs.
