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

# V2 Design
|
|
|
|
Current WAL V2 design set:
|
|
- `wal-replication-v2.md`
|
|
- `wal-replication-v2-state-machine.md`
|
|
- `wal-replication-v2-orchestrator.md`
|
|
- `wal-v2-tiny-prototype.md`
|
|
- `wal-v1-to-v2-mapping.md`
|
|
- `v2-dist-fsm.md`
|
|
- `v2_scenarios.md`
|
|
- `v1-v15-v2-comparison.md`
|
|
- `v2-scenario-sources-from-v1.md`
|
|
- `protocol-development-process.md`
|
|
- `v2-acceptance-criteria.md`
|
|
- `v2-open-questions.md`
|
|
- `v2-first-slice-session-ownership.md`
|
|
- `v2-prototype-roadmap-and-gates.md`
|
|
|
|
These documents are the working design home for the V2 line.
|
|
|
|
The original project-level copies under `learn/projects/sw-block/design/` remain as shared references for now.

|
Execution note:
|
|
- active development tracking for the current simulator phase lives under:
|
|
- `../.private/phase/phase-01.md`
|
|
- `../.private/phase/phase-02.md`
