## Outcome
Explain the selected ERP material and identify the implications for Phase 1 work.

## Selected evidence

Selected concept dossiers:

## Authority rules
- Treat current IESO-authored design memos as controlling program design unless a later Market Rule, Market Manual, or IESO publication supersedes them.
- Do not claim implementation unless a Market Rule, Market Manual, or other official implementation source proves it.
- Keep stakeholder submissions attributed to their authors; attribute stakeholder positions and do not present them as IESO decisions.
- Use superseded and historical sources only for lineage. Label what changed.
- Treat recordings as catalog-only unless a reviewed transcript is explicitly supplied.
- If two sources conflict, prefer the later higher-authority source and describe the conflict.

Cite every substantive claim with document title, publication date, page when available, document ID, and canonical URL. Never invent a page number.
