Sprint 02 - Platform Core Libraries¶
| Status | Progress | Last updated |
|---|---|---|
| DONE | 6/6 | 2026-06-22 |
Legend: DONE / IN PROGRESS / TODO / BLOCKED / DEFERRED. Cross-sprint rollup: ../STATUS.md.
Objective¶
Build the framework-agnostic internal platform (platform-core/*): the response/exception/context
primitives, the CQRS contracts, the in-process Mediator with its pipeline behaviors, and the
outbox/inbox cores. These modules MUST NOT import Spring (PLATFORM-SPEC hard rules). Starters
(Sprint 03) wrap them for Spring Boot.
Included Epics¶
- Epic 2: Platform Core Libraries (
platform-common,platform-cqrs,platform-mediator,platform-outbox,platform-inbox)
Cross-cutting constraints (apply to all tasks here)¶
platform-core/*may import only: JDK, slf4j-api, jakarta.validation-api (optional), jakarta annotations, Jackson annotations. No Spring.- GroupId
com.telco.platform, version1.0.0-SNAPSHOT. Base packages per PLATFORM-SPEC Section 1. - Records for immutable value types; every public type gets a short Javadoc.
Features (one file per top-level task)¶
| ID | Feature | Status | File |
|---|---|---|---|
| 2.1 | platform-common | DONE | 2.1-platform-common.md |
| 2.2 | platform-cqrs | DONE | 2.2-platform-cqrs.md |
| 2.3 | platform-mediator | DONE | 2.3-platform-mediator.md |
| 2.4 | platform-outbox | DONE | 2.4-platform-outbox.md |
| 2.5 | platform-inbox | DONE | 2.5-platform-inbox.md |
| 2.6 | Build and Verification | DONE | 2.6-build-and-verification.md |
Sprint Deliverables¶
platform-common(API contract, exceptions, context),platform-cqrs,platform-mediator(dispatcher + behaviors),platform-outboxcore,platform-inboxcore.- Unit-tested, Spring-free, building as a reactor.
Exit Criteria¶
- Platform-core reactor builds and tests pass.
- No Spring imports anywhere in
platform-core/*. - Mediator ordering/short-circuit, outbox record building, and inbox first-seen logic are covered by passing unit tests.
