Architecture Implementation Status

This page tracks implemented vs planned architecture capabilities.

Implemented

• Module-first lazy command registry (CommandRegistry, module package discovery).
• Bridge adapter contract and adapter registry usage in sync flows.
• ProjectBundle and change-tracking model support in core models.
• Mode detection and explicit mode selection.

Planned or Partial

• specfact architecture derive|validate|trace command family is planned.
  • Source: OpenSpec architecture-01-solution-layer.
• Protocol FSM runtime engine is partial (models/specs exist; full execution engine/guards are planned).
  • Source: OpenSpec architecture-01-solution-layer and dependent validation changes.
• Change tracking is adapter-dependent and not uniformly complete across all backlog providers.

Known limitations

• Documentation/specs may define forward-looking behavior before command implementation lands.
• Not all adapters implement the same depth for proposal/change-tracking persistence.
