pingqiuandClaude Opus 4.6 512bb5bcf6 fix: orchestrator owns full catch-up contract (budget + truncation) 
CompleteCatchUp now integrates:
- BeginCatchUp with start tick (freezes target)
- RecordCatchUpProgress (skips if already converged, e.g., truncation-only)
- CheckBudget at completion tick (escalates to NeedsRebuild + logs)
- RecordTruncation before completion (logs truncation_recorded)
- Logs causal reason for every rejection/escalation

CatchUpOptions: StartTick/CompleteTick (separate) + TruncateLSN.

3 new orchestrator-level tests:
- ReplicaAhead_TruncateViaOrchestrator: truncation through entry path
- ReplicaAhead_NoTruncate_CompletionRejected: logs completion_rejected
- BudgetEscalation_ViaOrchestrator: budget violation → NeedsRebuild + logs

Observability tests relabeled as sender-level (not entry-path).

pingqiuandClaude Opus 4.6 adaff8ddb3 fix: only log endpoint_changed when endpoint actually changed 
ProcessAssignment now compares pre/post endpoint state before
logging session_invalidated with "endpoint_changed" reason.
Normal session supersede (same endpoint, assignment_intent) no
longer mislabeled as endpoint change.

pingqiuandClaude Opus 4.6 5cdee4a011 fix: orchestrator owns zero-gap completion and per-replica invalidation logging 
Zero-gap completion:
- ExecuteRecovery auto-completes zero-gap sessions (no sender call needed)
- RecoveryResult.FinalState = StateInSync for zero-gap

Epoch transition:
- UpdateSenderEpoch: orchestrator-owned epoch advancement with auto-log
- InvalidateEpoch: per-replica session_invalidated events (not aggregate)

Endpoint-change invalidation:
- ProcessAssignment detects session ID change from endpoint update
- Logs per-replica session_invalidated with "endpoint_changed" reason

All integration tests now use orchestrator exclusively for core lifecycle.
No direct sender API calls for recovery execution in integration tests.

1 new test: EndpointChange_LogsInvalidation

pingqiuandClaude Opus 4.6 47238df0d7 fix: add RecoveryOrchestrator as real integrated entry path 
New: orchestrator.go — RecoveryOrchestrator drives recovery lifecycle
from assignment through execution to completion/escalation:
- ProcessAssignment: reconcile + session creation + auto-log
- ExecuteRecovery: connect → handshake from RetainedHistory → outcome
- CompleteCatchUp: begin catch-up → progress → complete + auto-log
- CompleteRebuild: connect → handshake → history-driven source →
  transfer → tail replay → complete + auto-log
- InvalidateEpoch: invalidate stale sessions + auto-log

All integration tests rewritten to use orchestrator as entry path.
No direct sender API calls in recovery lifecycle.

SessionSnapshot now includes: TruncateRequired/ToLSN/Recorded,
RebuildSource, RebuildPhase.

RecoveryLog is auto-populated by orchestrator at every transition.

7 integration tests via orchestrator:
- ChangedAddress, NeedsRebuild→Rebuild, EpochBump, MultiReplica
- Observability: session snapshot, rebuild snapshot, auto-populated log
