# GovOPlaN Workflow Engine Codex Guide

## Scope

This repository owns headless workflow definitions, immutable versions, validation, execution adapters, resumable state, human handoffs, and module-provided workflow baselines.

## Documentation Contract

- Treat documentation as part of every behavior change. Update this module's manifest-driven `DocumentationTopic` contributions for affected user and administrator behavior.
- Keep feature content here; `govoplan-docs` projects it without importing Workflow Engine internals.
- Maintain a static user/admin baseline and run `/mnt/DATA/git/govoplan/tools/checks/check-manifest-shapes.py` after behavior or manifest changes.

## Boundaries

- `govoplan-workflow` owns the optional editor; modules may define and run workflows through engine contracts without it.
- Preserve versioning, idempotency, authorization, recovery, and audit evidence at every transition.
