Adds sw-block/ directory with:
- distsim: protocol correctness simulator (96 tests)
- cluster model with epoch fencing, barrier semantics, commit modes
- endpoint identity, control-plane flow, candidate eligibility
- timeout events, timer races, same-tick ordering
- session ownership tracking with ID-based stale fencing
- enginev2: standalone V2 sender/session implementation (63 tests)
- per-replica Sender with identity-preserving reconciliation
- RecoverySession with FSM phase transitions and session ID
- execution APIs: BeginConnect, RecordHandshake, BeginCatchUp,
RecordCatchUpProgress, CompleteSessionByID — all sender-authority-gated
- recovery outcome branching: zero-gap, catch-up, needs-rebuild
- assignment-intent orchestration with epoch fencing
- design docs: acceptance criteria, open questions, first-slice spec,
protocol development process

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
