Exec Plan

Goal

Remove duplicated normalization ownership without changing the existing Interpreter, metric, or lexical-retrieval contracts.

Scope

In scope:

• Shared distribution and compatibility re-exports.
• A 50-case Vietnamese clinical characterization suite.
• CI, Docker, and setup instructions for the shared editable install.

Out of scope:

• Metric-baseline changes and matching-policy changes.

Risk Classification

Risk flags:

• Cross-module architecture and validation behavior.

Hard gates:

• Interpreter safety eval and risk fixtures remain unchanged.
• Existing metric and retrieval characterizations pass.

Work Phases

1. Capture contracts with deterministic cases.
2. Move the canonical Interpreter implementation to shared/.
3. Replace variants with direct imports.
4. Install shared package in every runtime path.
5. Run proof and record the Harness trace.
