ADR — PMS-owned customers; no Arsi integration at launch

TL;DR

m_customer lives in pms_schema and is authored in PMS (POST /customers or inline on projects). Arsi integration is deferred (no API). Conexus/CMS company catalogs are optional reference only.

Context

• 2026-05-21 emergency call: accelerate PMS; deprioritize non-urgent integrations.
• Arsi will not provide an API in time.
• Conexus t_comp_list is clean for existing transactional companies; PMS projects often target new prospects never in Conexus.
• Prior ERD/docs treated Conexus as SoT for m_customer.

Decision

1. Physical table: pms_schema.m_customer (unique code).
2. TypeORM: src/entity/pms/customer.entity.ts on uam connection — remove entity/conexus/.
3. API: GET + POST /customers; project create resolves customer_id from inline customer or customer_name.
4. No Arsi read/sync until an API exists.
5. CMS counterParties / Conexus — optional lookup helpers only.

Consequences

• Frontend must support full customer capture on create project (not Conexus picker-only).
• Duplicate codes rejected at DB (uq_m_customer_code).
• Future Conexus link can add optional conexus_code or import job without blocking MVP.
