# ADR 0012: Zero tech debt policy for editor UI

## Status

Accepted

## Context

The production editor program commits to shipping one correct path per feature rather than parallel “temporary” implementations.

## Decision

| Anti-pattern | Policy |
|--------------|--------|
| Dual inspector (ECS dump + authoring) | **Removed** from default Inspector; actor inspector only |
| Monolithic hydration | **Replaced** by `shared/hydration/*`; delete old function in same change |
| Optional `ActorKind` inference at runtime | **Migration + validation** only; no long-term guesswork |
| Deferred sub-phases (“Phase 3b”) | **Not used**; sibling order and related features ship in their named phase |
| Dead code after refactor | **Deleted in the same PR** |

## Consequences

- Each phase ends with a debt gate (tests green, old path removed, docs updated).
- New subsystems get ADR or editor doc entries when behavior is user-visible.
