pingqiuandClaude Opus 4.6 6fea93e821 feat: Task H — PendingCoordinator extracted to sw-block/engine/replication/runtime
New reusable pending-execution coordinator with fail-closed command matching:
- Store/TakeCatchUp/TakeRebuild/Cancel/Has/Peek
- TakeCatchUp: fail-closed on target LSN mismatch (cancel + return nil)
- TakeRebuild: same fail-closed semantics
- Cancel callback invoked on mismatch or explicit cancellation

9 tests prove boundary behavior:
- match succeeds, mismatch cancels, explicit cancel, noop on empty,
  peek non-destructive, store replaces, take from empty

No weed/ imports. Pure coordination logic reusable by any adapter shell.
weed/server/block_recovery.go rebinding deferred to Task I.

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
