E.20:9 - Consequences
Benefits
- Mechanism introductions become trainable and reviewable (a repeatable governing-definition map).
- Reduces drift by requiring one subject pattern for each mechanism meaning and keeping semantics in their subject pattern.
- Keeps suites descriptive and the P2W planning-to-work boundary inspectable.
- Supports SoTA evolution without destabilizing kernel meaning.
Costs
- Introductions use more explicit assignment records (governing-definition map, PQG coverage).
- Some changes will be split into multiple governed edits (by design), which increases authoring overhead.
- Kernel stability discipline can feel “slow” when a team wants a quick mutation.
