Bounded CatchUp: - CatchUpBudget: MaxDurationTicks, MaxEntries, ProgressDeadlineTicks - BudgetCheck: runtime consumption tracker (StartTick, EntriesReplayed, LastProgressTick) - Sender.CheckBudget: evaluates budget, escalates to NeedsRebuild on violation - RecordCatchUpProgressAt: tracks progress tick for stall detection - BeginCatchUp accepts optional startTick for budget tracking Rebuild state machine: - RebuildSource: snapshot_tail (preferred) vs full_base (fallback) - RebuildPhase: init → source_select → transfer → tail_replay → completed|aborted - SelectSource: chooses based on snapshot availability - Phase ordering enforced, transfer regression rejected - ReadyToComplete validates target reached 13 new tests: budget enforcement (duration, entries, stall, no-budget), sender budget integration, rebuild lifecycle (snapshot+tail, full base, abort, phase order, regression), E2E bounded catch-up → rebuild.

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.
