Cleanup: removed redundant TargetLSNAtStart from CatchUpBudget. FrozenTargetLSN on RecoverySession is the single source of truth. Acceptance traceability (acceptance_test.go): - A5: 3 evidence tests (unrecoverable gap, budget escalation, frozen target) - A6: 2 evidence tests (exact boundary, contiguity required) - A7: 3 evidence tests (snapshot history, catch-up replay, truncation) - A8: 2 evidence tests (convergence required, truncation required) Rebuild-source decision evidence: - snapshot_tail when trusted base exists - full_base when no snapshot or untrusted - 3 explicit tests 13 new tests total.

V2 Prototype
Experimental WAL V2 prototype code lives here.
Current prototype:
fsmv2/: pure in-memory replication FSM prototypevolumefsm/: volume-level orchestrator prototype abovefsmv2distsim/: early distributed/data-correctness simulator with synthetic 4K block values
Rules:
- do not wire this directly into WAL V1 production code
- keep interfaces and tests focused on architecture learning
- promote pieces into production only after V2 design stabilizes
Windows test workflow
Because normal go test may be blocked by Windows Defender when it executes temporary test binaries from %TEMP%, use:
powershell -ExecutionPolicy Bypass -File .\sw-block\prototype\run-tests.ps1
This builds test binaries into the workspace and runs them directly.
