Add host-side protocol state seam that derives per-replica execution
state from V2 sender/session snapshots and blocks live-tail WAL
shipping while an active recovery session is in progress.
New file: weed/server/block_protocol_state.go
- replicaProtocolExecutionState derived from engine snapshots
- LiveEligible=false during active catch-up/rebuild sessions
- bindProtocolExecutionPolicy wires policy into BlockVol
- syncProtocolExecutionState called after assignments + core events
Data plane changes:
- WALShipper.Ship() checks liveShippingPolicy before dial/send
- BlockVol.SetLiveShippingPolicy persists across shipper group rebuilds
- ShipperGroup propagates policy to all shippers
Design contract: sw-block/design/v2-protocol-aware-execution.md
Scope: WAL-first rollout only. Prevents illegal live-tail delivery
during active recovery. Does not change snapshot/build behavior or
move backlog. Next wave: bounded WAL catch-up under same contract.
Tests: 4 unit/component tests for phase gate behavior, plus bootstrap
seam tests that confirmed the two pre-existing bugs locally.

Move removed-replica drain and replica-scoped invalidation onto explicit core-command paths so the widened multi-replica runtime no longer depends on coarse host-side recovery handling.
Made-with: Cursor
Emit one core-owned start_recovery_task per primary catch-up replica so the bounded multi-replica startup path no longer depends on a single-replica assumption.
Made-with: Cursor
Track catch-up observations per replica so the volume-level recovery view stays in catching_up until all bounded replicas complete. This preserves the current bounded semantics while removing an overclaim that would block later multi-replica startup ownership work.
Made-with: Cursor
Carry replica-scoped addressing through bounded recovery planning and completion events so the core no longer depends on a volume-only observation seam. This preserves the current single-replica catch-up and rebuilding behavior while aligning the observation side with the replica-scoped command path.
Made-with: Cursor
Replace the remaining volume-scoped recovery command and pending slot
with replica-scoped addressing on the bounded core-present path. This
preserves the current single-replica catch-up and rebuilding behavior
while removing the structural blocker for later multi-replica startup
ownership.

Make the first V2 core owner explicit in sw-block by freezing Phase 14 docs, mode/readiness/publication semantics, and bounded command emission rules. This turns accepted Phase 13 constraints into executable core behavior without overclaiming live runtime cutover.
