The PMFA Canon

Canon I — Golden Path

There is exactly one legal execution path:

UI → Intent → Kernel → Event → Projection → Reality

Any alternative path is a constitutional violation.

There are no shortcuts.
There are no exceptions.
There is no "just this once."

Canon II — No-Engineering Principle

Business behavior may change in production
without code changes, builds, deployments, or downtime.

Engineering is forbidden at the behavior layer.

Engineering exists below the law, never above it.

Canon III — Determinism

Given the same inputs,
PMFA produces the same outcome—always.

This enables:
• Replay
• Audit
• Explanation
• Correction
• Regulatory trust

Canon IV — Structural Multi-Tenancy

Tenant isolation is structural, not conditional.

No tenant identifiers.
No shared tables.
No escape hatches.

Isolation is enforced by law.

Canon V — Irreversibility

Events are immutable.
Decisions are permanent.
History cannot be rewritten.

Corrections are new events—not mutations.
Rollback is compensation, not undo.

The past is constitutional record.
