pingqiuandClaude Opus 4.6 5aedada53a feat: Phase 18 M3 — replicated data continuity closure
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-block product structure clean enough to split into a separate repo later if needed

Suggested layout:

  • design/: shared V2 design docs
  • prototype/: 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 inside seaweedfs
  • likely future state: sw-block becomes a standalone sibling repo/product
  • design and prototype structure should therefore stay product-oriented and not depend on SeaweedFS-specific paths
