[PR] Add GeaFlowBackend backend vertical slice design document [geaflow]
Mugetsu-bankai opened a new pull request, #870:
URL: https://github.com/apache/geaflow/pull/870
### What changes were proposed in this pull request?
This PR adds the design/scoping document `Gearflow-backend-vertical-slice.md` for apache/geaflow#849.
The document defines the minimal vertical slice that lets a `GeaFlowBackend` treat the real GeaFlow engine as a backend of `geaflow-ai` through one shared, stable, testable interface. It covers:
- Current state and existing seams: `GraphAccessor`, `MutableGraph`, `GraphComputeEngine`, `GraphMemoryServer`, and the in-memory `MemoryGraph` path.
- Goals and scope of the first vertical slice.
- Three candidate approaches:
- Option A: read-only slice
- Option B: write-through slice (recommended)
- Option C: projector-based slice
- A decision matrix comparing write-path coverage, write → restart → read loop, runtime surface touched, effort, and fallback safety.
- Supported operations for the baseline assuming Option B, explicit non-goals, and mapping to existing GeaFlow DSL/runtime components.
- Checkpoint behavior, missing APIs/blockers to resolve, test strategy, rollback/compatibility paths, open questions, and the final recommendation.
- Recommendation: proceed with Option B (write-through) as the primary vertical slice, with Option A as a committed fallback. Resolve the open design questions in the design phase before implementation.
This is a documentation/design-only change. It does not implement the vertical slice, add production HA guarantees, or modify runtime code.
