pingqiu 43dbebfa04 refactor: close bounded recovery drain and invalidation seams 
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.

pingqiu 5fd9ec0edf refactor: widen bounded multi-replica catch-up startup ownership 
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.

pingqiu 16ba70f856 refactor: make bounded recovery observation events replica-scoped 
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.

pingqiuandClaude Opus 4.6 b304b8e212 refactor: make bounded recovery command addressing replica-scoped 
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.

pingqiuandClaude Opus 4.6 11c6aaf316 feat: Batch 7 + Phase 16C-E — command dispatch extraction + engine refinements 
Batch 7: Command dispatch binding extraction
- New weed/server/blockcmd package: CommandHandler interface + DispatchCommands
- volume_server_block.go applyCoreCommandsWithAssignment delegates to dispatcher
- weed/server still owns RecordCommand, EmitCoreEvent, PublishProjection
- v2bridge NOT given command-switch or event-emission semantics

Phase 16C: Rebuilding assignment enters core command path
Phase 16D: Rebuild recovery-task startup is command-driven
Phase 16E: Catch-up recovery-task startup is command-driven

Engine refinements:
- RecoveryTarget on AssignmentDelivered event
- shouldStartRecoveryTask / shouldStartReceiver guards
- bootstrapReason: awaiting_rebuild_start

Bridge/contract updates:
- control_adapter.go: refined translation helpers
- contract.go: executor port alignment

Migration design docs (Batch 1-3 delivered, design artifacts):
- v2-first/second/third-migration-batch.md + task-pack.md
- v2-assignment-translation-unification.md
- v2-execution-muscles-inventory.md
- v2-separation-port-layer-audit.md
- v2-legacy-runtime-exit-criteria.md

pingqiuandClaude Opus 4.6 a6fc8545b9 feat: Phase 14A+14B — V2 core publication ownership + command semantics 
14A: Publication as explicit core-owned state
- state.go: PublicationView on VolumeState, explicit gate reasons
- engine.go: mode→readiness→publication chain with named gates
  (awaiting_role_apply, awaiting_shipper_configured, awaiting_barrier_durability)
- projection.go: PublicationProjection carries publication truth
- RF=1/no-replicas → allocated_only (CP13-9 constraint in core)
- phase14_core_test.go: strengthened publication closure + RF=1 proof

14B: Command emission bounded by semantic gap
- engine.go: repeated same-assignment skips redundant commands,
  repeated same-reason BarrierRejected skips duplicate invalidation,
  command-state tracking on VolumeState
- command.go: new command types for bounded emission
- event.go: new boundary events
- phase14_command_test.go: exact command sequences frozen as proofs
  (primary/replica repeated assignment, assignment changed, repeated failure)
- phase14_boundary_test.go: boundary/recovery structural tests

All tests pass in sw-block/engine/replication.
Phase 14 docs updated (14A accepted, 14B active→14C planned).

pingqiu fb0da91196 feat: start Phase 14 V2 core shell 
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.
