M3 milestone: write → Loop2 observe → failover → readback verify. Continuity runtime (continuity_runtime.go): - ExecuteReplicatedContinuity: composes mirror write + sync + Loop2 observation + failover + readback verify into one bounded path - ReplicatedContinuityResult: captures pre-failover Loop2 snapshot, failover result, selected primary, readback length, data match Runtime manager extensions: - Local node registry for write/readback during continuity verification - RegisterNode now stores node reference for local I/O access Tests prove two paths: - Happy: write on source → failover → promoted node reads correct data - Gated: degraded peer → failover gate stops → continuity reports failure Phase 18 docs: M3 delivered, M4 next.

sw-block
Private WAL V2 and standalone block-service workspace.
Purpose:
- keep WAL V2 design/prototype work isolated from WAL V1 production code in
weed/storage/blockvol - allow private design notes and experiments to evolve without polluting V1 delivery paths
- keep the future standalone
sw-blockproduct structure clean enough to split into a separate repo later if needed
Suggested layout:
design/: shared V2 design docsprototype/: code prototypes and experiments.private/: private notes, phase development, roadmap, and non-public working material
Repository direction:
- current state:
sw-block/is an isolated workspace insideseaweedfs - likely future state:
sw-blockbecomes a standalone sibling repo/product - design and prototype structure should therefore stay product-oriented and not depend on SeaweedFS-specific paths
