Architecture decisions explained

01
Why Integration-Heavy?
?

Is the "inverted pyramid" a problem?

No — it's deliberate. KagamiOS differs from CRUD apps:

1. CBF spans componentsh(x) ≥ 0 must hold across Spark → Forge → Flow → Nexus.
2. 7-Colony architecture — Interesting behaviors emerge at boundaries.
3. ML systems are different — Model behavior is emergent, not unit-testable.

7-Colony Architecture
Spark — Intent parsing
Forge — Asset generation
Flow — Workflows
Nexus — Memory & routing
Beacon — Observability
Grove — Knowledge
Crystal — World model

Colonies communicate via Fano plane routing: any two share exactly one path.
h

CBF: h(x) ≥ 0

Control Barrier Function ensures safety:
h(x) > 0 = safe
h(x) = 0 = boundary
h(x) < 0 = forbidden

Quality

Working Well

• Property-based testing (190+ Hypothesis tests)
• Contract testing (Syrupy snapshots)
• Chaos engineering (79 failure scenario tests)
• CBF safety explicitly tested
!

Needs Work

• Satellite coverage (import-only tests)
• Dependency conflict (124 tests blocked)
• World model stability (87 failures)
• Contract drift (37 snapshots)
