Document Transcription System Overview (Version 4)

This directory is the single source of truth for current V4 behavior and architecture.

Canonical Reading Order

1. System Architecture for runtime topology, boundaries, and lifecycle ownership.
2. System Requirements for verifiable current-state requirements.
3. Data Model for entities, constraints, and evidence persistence rules.
4. Error Handling Policy for category, translation, and retry behavior.
5. V4 Revision History for superseded scope and implementation documents.

Baseline Statement

The current V4 baseline includes behavior delivered through V4.7 architectural cleanup. Versioned V4.x scope and implementation documents are retained as historical records only at git tag docs-v4x-archive and do not define active contracts.
