Sprint 09 - Subscription and Onboarding Saga

Status Progress Last updated
TODO 0/5 2026-06-22

Legend: DONE / IN PROGRESS / TODO / BLOCKED / DEFERRED. Cross-sprint rollup: ../STATUS.md.

Objective

Build subscription-service (9005) with its lifecycle state machine and MSISDN allocation, then wire the end-to-end new-line onboarding saga (order -> payment -> subscription -> fulfillment + welcome SMS) including compensation on failure. Completing this sprint delivers acceptance criterion AC-01.

Covers FR-13, FR-14, FR-15 (FR-16 MNP is post-MVP, scaffolded only) and the saga orchestration of FR-10/FR-12.

Sprint Deliverables

  • subscription-service (9005): lifecycle state machine, atomic MSISDN allocation/release, activation and lifecycle endpoints, MNP scaffold (deferred), and subscription events.
  • Fully wired onboarding saga across order/payment/subscription with compensation.
  • AC-01 end-to-end integration test (happy path and compensation).

Exit Criteria

  • AC-01 passes end to end: a registered, KYC-approved customer orders a postpaid tariff, pays via mock PSP, gets an automatically activated subscription with an allocated MSISDN, a welcome signal, and a FULFILLED order.
  • A forced activation failure compensates (refund + order CANCELLED) with no dangling MSISDN.
  • FR-13, FR-14, FR-15 pass; FR-10 and FR-12 saga behavior validated; FR-16 scaffolded as post-MVP.
