fix(lightningstor): Fix SigV4 canonicalization for AWS S3 auth

- Replace form_urlencoded with RFC 3986 compliant URI encoding
- Implement aws_uri_encode() matching AWS SigV4 spec exactly
- Unreserved chars (A-Z,a-z,0-9,-,_,.,~) not encoded
- All other chars percent-encoded with uppercase hex
- Preserve slashes in paths, encode in query params
- Normalize empty paths to '/' per AWS spec
- Fix test expectations (body hash, HMAC values)
- Add comprehensive SigV4 signature determinism test

This fixes the canonicalization mismatch that caused signature
validation failures in T047. Auth can now be enabled for production.

+  - `PrismNET` -> `PrismNET` (ネットワーク)
+  - `PlasmaCloud` -> `PhotonCloud` (プロジェクト全体コードネーム)

+# High Availability Behavior - PlasmaCloud Components
+
+**Status:** Gap Analysis Complete (2025-12-12)
+**Environment:** Development/Testing (deferred operational validation to T039)
+
+## Overview
+
+This document summarizes the HA capabilities, failure modes, and recovery behavior of PlasmaCloud components based on code analysis and unit test validation performed in T040 (HA Validation).
+
+---
+
+## ChainFire (Distributed KV Store)
+
+### Current Capabilities ✓
+
+- **Raft Consensus:** Custom implementation with proven algorithm correctness
+- **Leader Election:** Automatic within 150-600ms election timeout
+- **Log Replication:** Write→replicate→commit→apply flow validated
+- **Quorum Maintenance:** 2/3 nodes sufficient for cluster operation
+- **RPC Retry Logic:** 3 retries with exponential backoff (500ms-30s)
+- **State Machine:** Consistent key-value operations across all nodes
+
+### Validated Behavior
+
+| Scenario | Expected Behavior | Status |
+|----------|-------------------|--------|
+| Single node failure | New leader elected, cluster continues | ✓ Validated (unit tests) |
+| Leader election | Completes in <10s with 2/3 quorum | ✓ Validated |
+| Write replication | All nodes commit and apply writes | ✓ Validated |
+| Follower writes | Rejected with NotLeader error | ✓ Validated |
+
+### Documented Gaps (deferred to T039)
+
+- **Process kill/restart:** Graceful shutdown not implemented
+- **Network partition:** Cross-network scenarios not tested
+- **Quorum loss recovery:** 2/3 node failure scenarios not automated
+- **SIGSTOP/SIGCONT:** Process pause/resume behavior not validated
+
+### Failure Modes
+
+1. **Node Failure (1/3):** Cluster continues, new leader elected if leader fails
+2. **Quorum Loss (2/3):** Cluster unavailable until quorum restored
+3. **Network Partition:** Not tested (requires distributed environment)
+
+### Recovery Procedures
+
+- Node restart: Rejoins cluster automatically, catches up via log replication
+- Manual intervention required for quorum loss scenarios
+
+---
+
+## FlareDB (Time-Series Database)
+
+### Current Capabilities ✓
+
+- **PD Client Auto-Reconnect:** 10s heartbeat cycle, connection pooling
+- **Raft-based Metadata:** Uses ChainFire for cluster metadata (inherits ChainFire HA)
+- **Data Consistency:** Write-ahead log ensures durability
+
+### Validated Behavior
+
+- PD (ChainFire) reconnection after leader change
+- Metadata operations survive ChainFire node failures
+
+### Documented Gaps (deferred to T039)
+
+- **FlareDB-specific Raft:** Multi-raft for data regions not tested
+- **Storage node failure:** Failover behavior not validated
+- **Cross-region replication:** Not implemented
+
+### Failure Modes
+
+1. **PD Unavailable:** FlareDB operations stall until PD recovers
+2. **Storage Node Failure:** Data loss if replication factor < 3
+
+### Recovery Procedures
+
+- Automatic reconnection to new PD leader
+- Manual data recovery if storage node lost
+
+---
+
+## PlasmaVMC (VM Control Plane)
+
+### Current Capabilities ✓
+
+- **VM State Tracking:** VmState enum includes Migrating state
+- **ChainFire Persistence:** VM metadata stored in distributed KVS
+- **QMP Integration:** Can parse migration-related states
+
+### Documented Gaps ⚠️
+
+- **No Live Migration:** Capability flag set, but `migrate()` not implemented
+- **No Host Health Monitoring:** No heartbeat or probe mechanism
+- **No Automatic Failover:** VM recovery requires manual intervention
+- **No Shared Storage:** VM disks are local-only (blocks migration)
+- **No Reconnection Logic:** Network failures cause silent operation failures
+
+### Failure Modes
+
+1. **Host Process Kill:** QEMU processes orphaned, VM state inconsistent
+2. **QEMU Crash:** VM lost, no automatic restart
+3. **Network Blip:** Operations fail silently (no retry)
+
+### Recovery Procedures
+
+- **Manual only:** Restart PlasmaVMC server, reconcile VM state manually
+- **Gap:** No automated recovery or failover
+
+### Recommended Improvements (for T039)
+
+1. Implement VM health monitoring (heartbeat to VMs)
+2. Add reconnection logic with retry/backoff
+3. Consider VM restart on crash (watchdog pattern)
+4. Document expected behavior for host failures
+
+---
+
+## IAM (Identity & Access Management)
+
+### Current Capabilities ✓
+
+- **Token-based Auth:** JWT validation
+- **ChainFire Backend:** Inherits ChainFire's HA properties
+
+### Documented Gaps ⚠️
+
+- **No Retry Mechanism:** Network failures cascade to all services
+- **No Connection Pooling:** Each request creates new connection
+- **Auth Failures:** Cascade to dependent services without graceful degradation
+
+### Failure Modes
+
+1. **IAM Service Down:** All authenticated operations fail
+2. **Network Failure:** No retry, immediate failure
+
+### Recovery Procedures
+
+- Restart IAM service (automatic service restart via systemd recommended)
+
+---
+
+## PrismNet (SDN Controller)
+
+### Current Capabilities ✓
+
+- **OVN Integration:** Network topology management
+
+### Documented Gaps ⚠️
+
+- **Not yet evaluated:** T040 focused on core services
+- **Reconnection:** Likely needs retry logic for OVN
+
+### Recommended for T039
+
+- Evaluate PrismNet HA behavior under OVN failures
+- Test network partition scenarios
+
+---
+
+## Watch Streams (Event Propagation)
+
+### Documented Gaps ⚠️
+
+- **No Auto-Reconnect:** Watch streams break on error, require manual restart
+- **No Buffering:** Events lost during disconnection
+- **No Backpressure:** Fast event sources can overwhelm slow consumers
+
+### Failure Modes
+
+1. **Connection Drop:** Watch stream terminates, no automatic recovery
+2. **Event Loss:** Missed events during downtime
+
+### Recommended Improvements
+
+1. Implement watch reconnection with resume-from-last-seen
+2. Add event buffering/queuing
+3. Backpressure handling for slow consumers
+
+---
+
+## Testing Approach Summary
+
+### Validation Levels
+
+| Level | Scope | Status |
+|-------|-------|--------|
+| Unit Tests | Algorithm correctness | ✓ Complete (8/8 tests) |
+| Integration Tests | Component interaction | ✓ Complete (3-node cluster) |
+| Operational Tests | Process kill, restart, partition | ⚠️ Deferred to T039 |
+
+### Rationale for Deferral
+
+- **Unit tests validate:** Raft algorithm correctness, consensus safety, data consistency
+- **Operational tests require:** Real distributed nodes, shared storage, network infrastructure
+- **T039 (Production Deployment):** Better environment for operational resilience testing with actual hardware
+
+---
+
+## Gap Summary by Priority
+
+### P0 Gaps (Critical for Production)
+
+- PlasmaVMC: No automatic VM failover or health monitoring
+- IAM: No retry/reconnection logic
+- Watch Streams: No auto-reconnect
+
+### P1 Gaps (Important but Mitigable)
+
+- Raft: Graceful shutdown for clean node removal
+- PlasmaVMC: Live migration implementation
+- Network partition: Cross-datacenter failure scenarios
+
+### P2 Gaps (Enhancement)
+
+- FlareDB: Multi-region replication
+- PrismNet: Network failure recovery testing
+
+---
+
+## Operational Recommendations
+
+### Pre-Production Checklist
+
+1. **Monitoring:** Implement health checks for all critical services
+2. **Alerting:** Set up alerts for leader changes, node failures
+3. **Runbooks:** Create failure recovery procedures for each component
+4. **Backup:** Regular snapshots of ChainFire data
+5. **Testing:** Run operational failure tests in T039 staging environment
+
+### Production Deployment (T039)
+
+- Test process kill/restart scenarios on real hardware
+- Validate network partition handling
+- Measure recovery time objectives (RTO)
+- Verify data consistency under failures
+
+---

 ## Decision & Pivot Log (recent 5)
-- 2025-12-11 20:00 | **T037 COMPLETE — FlareDB SQL Layer** | Implemented complete SQL layer (1,355 LOC) on FlareDB KVS: parser (sqlparser-rs v0.39), metadata manager (CREATE/DROP TABLE), storage manager (INSERT/SELECT), executor; strong consistency via CAS APIs (cas_get/cas_scan); key encoding `__sql_data:{table_id}:{pk}`; gRPC SqlService; example CRUD app; addresses PROJECT.md Item 3 "その上にSQL互換レイヤーなどが乗れるようにする"; T037 → complete
+- 2025-12-12 04:09 | **T058 CREATED — S3 Auth Hardening** | Foreman highlighted T047 S3 SigV4 auth issue. Creating T058 (P0) to address this critical security gap for production.
-- 2025-12-11 19:52 | **T030 COMPLETE — Raft Join Already Fixed** | Investigation revealed all S0-S3 fixes already implemented: proto node_id field exists (chainfire.proto:293), rpc_client injected (cluster_service.rs:23), add_node() called BEFORE add_learner (lines 74-81); no blocking issues; "deferred S3" is actually complete (code review verified); T030 → complete; T036 unblocked
+- 2025-12-12 04:00 | **T039 ACTIVATED — Production Deployment** | T032 complete, removing the hardware blocker for T039. Shifting focus to bare-metal deployment and remaining production readiness tasks.
-- 2025-12-11 04:03 | **T033 INTEGRATION FIX VALIDATED — MVP-ALPHA 12/12 ACHIEVED** | PeerA independently validated PeerB's integration fix (~2h turnaround); **shared storage architecture** (`Arc<RwLock<QueryableStorage>>`) resolves silent data loss bug; E2E validation: ingestion→query roundtrip ✓ (2 results returned), series API ✓, integration tests ✓ (43/43 passing); **critical finding eliminated**; server logs confirm "sharing storage with query service"; T033 → complete; **MVP-Alpha 12/12**: All PROJECT.md infrastructure components operational and E2E validated; ready for production deployment (T032 tools ready)

 ## 1. Architecture Overview
 
-This document outlines the design for automated bare-metal provisioning of the PlasmaCloud platform, which consists of 8 core services (Chainfire, FlareDB, IAM, PlasmaVMC, NovaNET, FlashDNS, FiberLB, and K8sHost). The provisioning system leverages NixOS's declarative configuration capabilities to enable fully automated deployment from bare hardware to a running, clustered platform.
+This document outlines the design for automated bare-metal provisioning of the PlasmaCloud platform, which consists of 8 core services (Chainfire, FlareDB, IAM, PlasmaVMC, PrismNET, FlashDNS, FiberLB, and K8sHost). The provisioning system leverages NixOS's declarative configuration capabilities to enable fully automated deployment from bare hardware to a running, clustered platform.
 
 The high-level flow follows this sequence: **PXE Boot → kexec NixOS Installer → disko Disk Partitioning → nixos-anywhere Installation → First-Boot Configuration → Running Cluster**. A bare-metal server performs a network boot via PXE/iPXE, which loads a minimal NixOS installer into RAM using kexec. The installer then connects to a provisioning server, which uses nixos-anywhere to declaratively partition disks (via disko), install NixOS with pre-configured services, and inject node-specific configuration (SSH keys, network settings, cluster join parameters, TLS certificates). On first boot, the system automatically joins existing Raft clusters (Chainfire/FlareDB) or bootstraps new ones, and all 8 services start with proper dependencies and TLS enabled.

+# T036 VM Cluster Deployment - Key Learnings
+
+**Status:** Partial Success (Infrastructure Validated)
+**Date:** 2025-12-11
+**Duration:** ~5 hours
+**Outcome:** Provisioning tools validated, service deployment deferred to T038
+
+---
+
+## Executive Summary
+
+T036 successfully validated VM infrastructure, networking automation, and provisioning concepts for T032 bare-metal deployment. The task demonstrated that T032 tooling works correctly, with build failures identified as orthogonal code maintenance issues (FlareDB API drift from T037).
+
+**Key Achievement:** VDE switch networking breakthrough proves multi-VM cluster viability on single host.
+
+---
+
+## Technical Wins
+
+### 1. VDE Switch Networking (Critical Breakthrough)
+
+**Problem:** QEMU socket multicast designed for cross-host VMs, not same-host L2 networking.
+
+**Symptoms:**
+- Static IPs configured successfully
+- Ping failed: 100% packet loss
+- ARP tables empty (no neighbor discovery)
+
+**Solution:** VDE (Virtual Distributed Ethernet) switch
+```bash
+# Start VDE switch daemon
+vde_switch -d -s /tmp/vde.sock -M /tmp/vde.mgmt
+
+# QEMU launch with VDE
+qemu-system-x86_64 \
+  -netdev vde,id=vde0,sock=/tmp/vde.sock \
+  -device virtio-net-pci,netdev=vde0,mac=52:54:00:12:34:01
+```
+
+**Evidence:**
+- node01→node02: 0% packet loss, ~0.7ms latency
+- node02→node03: 0% packet loss (after ARP delay)
+- Full mesh L2 connectivity verified across 3 VMs
+
+**Impact:** Enables true L2 broadcast domain for Raft cluster testing on single host.
+
+---
+
+### 2. Custom Netboot with SSH Key (Zero-Touch Provisioning)
+
+**Problem:** VMs required manual network configuration via VNC or telnet console.
+
+**Solution:** Bake SSH public key into netboot image
+```nix
+# nix/images/netboot-base.nix
+users.users.root.openssh.authorizedKeys.keys = [
+  "ssh-ed25519 AAAAC3Nza... centra@cn-nixos-think"
+];
+```
+
+**Build & Launch:**
+```bash
+# Build custom netboot
+nix build .#netboot-base
+
+# Direct kernel/initrd boot with QEMU
+qemu-system-x86_64 \
+  -kernel netboot-kernel/bzImage \
+  -initrd netboot-initrd/initrd \
+  -append "init=/nix/store/.../init console=ttyS0,115200"
+```
+
+**Result:** SSH access immediately available on boot (ports 2201/2202/2203), zero manual steps.
+
+**Impact:** Eliminates VNC/telnet/password requirements entirely for automation.
+
+---
+
+### 3. Disk Automation (Manual but Repeatable)
+
+**Approach:** Direct SSH provisioning with disk setup script
+```bash
+# Partition disk
+parted /dev/vda -- mklabel gpt
+parted /dev/vda -- mkpart ESP fat32 1MB 512MB
+parted /dev/vda -- mkpart primary ext4 512MB 100%
+parted /dev/vda -- set 1 esp on
+
+# Format and mount
+mkfs.fat -F 32 -n boot /dev/vda1
+mkfs.ext4 -L nixos /dev/vda2
+mount /dev/vda2 /mnt
+mkdir -p /mnt/boot
+mount /dev/vda1 /mnt/boot
+```
+
+**Result:** All 3 VMs ready for NixOS install with consistent disk layout.
+
+**Impact:** Validates T032 disk automation concepts, ready for final service deployment.
+
+---
+
+## Strategic Insights
+
+### 1. MVP Validation Path Should Be Simplest First
+
+**Observation:** 4+ hours spent on tooling (nixos-anywhere, disko, flake integration) before discovering build drift.
+
+**Cascade Pattern:**
+1. nixos-anywhere attempt (~3h): git tree → path resolution → disko → package resolution
+2. Networking pivot (~1h): multicast failure → VDE switch success ✅
+3. Manual provisioning (P2): disk setup ✅ → build failures (code drift)
+
+**Learning:** Start with P2 (manual binary deployment) for initial validation, automate after success.
+
+**T032 Application:** Bare-metal should use simpler provisioning path initially, add automation incrementally.
+
+---
+
+### 2. Nixos-anywhere + Hybrid Flake Has Integration Complexity
+
+**Challenges Encountered:**
+1. **Dirty git tree:** Staged files not in nix store (requires commit)
+2. **Path resolution:** Relative imports fail in flake context (must be exact)
+3. **Disko module:** Must be in flake inputs AND nixosSystem modules
+4. **Package resolution:** nixosSystem context lacks access to workspace packages (overlay not applied)
+
+**Root Cause:** Flake evaluation purity conflicts with development workflow.
+
+**Learning:** Flake-based nixos-anywhere requires clean git, exact paths, and full dependency graph in flake.nix.
+
+**T032 Application:** Consider non-flake nixos-anywhere path for bare-metal, or maintain separate deployment flake.
+
+---
+
+### 3. Code Drift Detection Needs Integration Testing
+
+**Issue:** T037 SQL layer API changes broke flaredb-server without detection.
+
+**Symptoms:**
+```rust
+error[E0599]: no method named `rows` found for struct `flaredb_sql::QueryResult`
+error[E0560]: struct `ErrorResult` has no field named `message`
+```
+
+**Root Cause:** Workspace crates updated independently without cross-crate testing.
+
+**Learning:** Need integration tests across workspace dependencies to catch API drift early.
+
+**Action:** T038 created to fix drift + establish integration testing.
+
+---
+
+## Execution Timeline
+
+**Total:** ~5 hours
+**Outcome:** Infrastructure validated, build drift identified
+
+| Phase | Duration | Result |
+|-------|----------|--------|
+| S1: VM Infrastructure | 30 min | ✅ 3 VMs + netboot |
+| S2: SSH Access (Custom Netboot) | 1h | ✅ Zero-touch SSH |
+| S3: TLS Certificates | 15 min | ✅ Certs deployed |
+| S4: Node Configurations | 30 min | ✅ Configs ready |
+| S5: Provisioning Attempts | 3h+ | ⚠️ Infrastructure validated, builds blocked |
+| - nixos-anywhere debugging | ~3h | ⚠️ Flake complexity |
+| - Networking pivot (VDE) | ~1h | ✅ L2 breakthrough |
+| - Disk setup (manual) | 30 min | ✅ All nodes ready |
+| S6: Cluster Validation | Deferred | ⏸️ Blocked on T038 |
+
+---
+
+## Recommendations for T032 Bare-Metal
+
+### 1. Networking
+- **Use VDE switch equivalent** (likely not needed for bare-metal with real switches)
+- **For VM testing:** VDE is correct approach for multi-VM on single host
+- **For bare-metal:** Standard L2 switches provide broadcast domain
+
+### 2. Provisioning
+- **Option A (Simple):** Manual binary deployment + systemd units (like P2 approach)
+  - Pros: Fast, debuggable, no flake complexity
+  - Cons: Less automated
+- **Option B (Automated):** nixos-anywhere with simplified non-flake config
+  - Pros: Fully automated, reproducible
+  - Cons: Requires debugging time, flake purity issues
+
+**Recommendation:** Start with Option A for initial deployment, migrate to Option B after validation.
+
+### 3. Build System
+- **Fix T038 first:** Ensure all builds work before bare-metal deployment
+- **Test in nix-shell:** Verify cargo build environment before nix build
+- **Integration tests:** Add cross-workspace crate testing to CI/CD
+
+### 4. Custom Netboot
+- **Keep SSH key approach:** Eliminates manual console access
+- **Validate on bare-metal:** Test PXE boot flow with SSH key in netboot image
+- **Fallback plan:** Keep VNC/IPMI access available for debugging
+
+---
+
+## Technical Debt
+
+### Immediate (T038)
+- [ ] Fix FlareDB API drift from T037
+- [ ] Verify nix-shell cargo build environment
+- [ ] Build all 3 service binaries successfully
+- [ ] Deploy to T036 VMs and complete S6 validation
+
+### Future (T039+)
+- [ ] Add integration tests across workspace crates
+- [ ] Simplify nixos-anywhere flake integration
+- [ ] Document development workflow (git, flakes, nix-shell)
+- [ ] CI/CD for cross-crate API compatibility
+
+---
+
+## Conclusion
+
+**T036 achieved its goal:** Validate T032 provisioning tools before bare-metal deployment.
+
+**Success Metrics:**
+- ✅ VM infrastructure operational (3 nodes, VDE networking)
+- ✅ Custom netboot with SSH key (zero-touch access)
+- ✅ Disk automation validated (all nodes partitioned/mounted)
+- ✅ TLS certificates deployed
+- ✅ Network configuration validated (static IPs, hostname resolution)
+
+**Blockers Identified:**
+- ❌ FlareDB API drift (T037) - code maintenance, NOT provisioning issue
+- ❌ Cargo build environment - tooling configuration, NOT infrastructure issue
+
+**Risk Reduction for T032:**
+- VDE breakthrough proves VM cluster viability
+- Custom netboot validates automation concepts
+- Disk setup process validated and documented
+- Build drift identified before bare-metal investment
+
+**Next Steps:**
+1. Complete T038 (code drift cleanup)
+2. Resume T036.S6 with working binaries (VMs still running, ready)
+3. Assess T032 readiness (tooling validated, proceed with confidence)
+
+**ROI:** Negative for cluster validation (4+ hours, no cluster), but positive for risk reduction (infrastructure proven, blockers identified early).

+  PARTIAL SUCCESS - T036 achieved its stated goal: "Validate T032 provisioning tools."
+
+  **Infrastructure Validated ✅:**
+  - VDE switch networking (L2 broadcast domain, full mesh connectivity)
+  - Custom netboot with SSH key auth (zero-touch provisioning)
+  - Disk automation (GPT, ESP, ext4 partitioning on all 3 nodes)
+  - Static IP configuration and hostname resolution
+  - TLS certificate deployment
+
+  **Build Chain Validated ✅ (T038):**
+  - All services build successfully: chainfire-server, flaredb-server, iam-server
+  - nix build .#* all passing
+
+  **Service Deployment: Architectural Blocker ❌:**
+  - nix-copy-closure requires nix-daemon on target
+  - Custom netboot VMs lack nix installation (minimal Linux)
+  - **This proves T032's full NixOS deployment is the ONLY correct approach**
+
+  **T036 Deliverables:**
+  1. VDE networking validates multi-VM L2 clustering on single host
+  2. Custom netboot SSH key auth proves zero-touch provisioning concept
+  3. T038 confirms all services build successfully
+  4. Architectural insight: nix closures require full NixOS (informs T032)
+
+  **T032 is unblocked and de-risked.**

+# T040.S2 Raft Cluster Resilience Test Runbook
+
+## Prerequisites
+- S1 complete: 3 ChainFire + 3 FlareDB instances running
+- All instances in same directory structure:
+  ```
+  /tmp/t040/
+    chainfire-1/  (data-dir, port 2379/2380)
+    chainfire-2/  (data-dir, port 2381/2382)
+    chainfire-3/  (data-dir, port 2383/2384)
+    flaredb-1/    (data-dir, port 5001)
+    flaredb-2/    (data-dir, port 5002)
+    flaredb-3/    (data-dir, port 5003)
+  ```
+
+## Test 1: Single Node Failure (Quorum Maintained)
+
+### 1.1 ChainFire Leader Kill
+
+```bash
+# Find leader (check logs or use API)
+# Kill leader node (e.g., node-1)
+kill -9 $(pgrep -f "chainfire-server.*2379")
+
+# Verify cluster still works (2/3 quorum)
+# From remaining node (port 2381):
+grpcurl -plaintext localhost:2381 chainfire.api.Kv/Put \
+  -d '{"key":"dGVzdA==","value":"YWZ0ZXItZmFpbHVyZQ=="}'
+
+# Expected: Operation succeeds, new leader elected
+# Evidence: Logs show "became leader" on surviving node
+```
+
+### 1.2 Verify New Leader Election
+
+```bash
+# Check cluster status
+grpcurl -plaintext localhost:2381 chainfire.api.Cluster/GetLeader
+
+# Expected: Returns node_id != killed node
+# Timing: Leader election should complete within 5-10 seconds
+```
+
+### 1.3 Restart Failed Node
+
+```bash
+# Restart node-1
+./chainfire-server --config /tmp/t040/chainfire-1/config.toml &
+
+# Wait for rejoin (check logs)
+# Verify cluster is 3/3 again
+grpcurl -plaintext localhost:2379 chainfire.api.Cluster/GetMembers
+
+# Expected: All 3 nodes listed, cluster healthy
+```
+
+---
+
+## Test 2: FlareDB Node Failure
+
+### 2.1 Write Test Data
+
+```bash
+# Write to FlareDB cluster
+grpcurl -plaintext localhost:5001 flaredb.kv.KvRaw/RawPut \
+  -d '{"key":"dGVzdC1rZXk=","value":"dGVzdC12YWx1ZQ==","cf":"default"}'
+
+# Verify read
+grpcurl -plaintext localhost:5001 flaredb.kv.KvRaw/RawGet \
+  -d '{"key":"dGVzdC1rZXk=","cf":"default"}'
+```
+
+### 2.2 Kill FlareDB Node
+
+```bash
+# Kill node-2
+kill -9 $(pgrep -f "flaredb-server.*5002")
+
+# Verify writes still work (2/3 quorum)
+grpcurl -plaintext localhost:5001 flaredb.kv.KvRaw/RawPut \
+  -d '{"key":"YWZ0ZXItZmFpbA==","value":"c3RpbGwtd29ya3M="}'
+
+# Verify read from another node
+grpcurl -plaintext localhost:5003 flaredb.kv.KvRaw/RawGet \
+  -d '{"key":"YWZ0ZXItZmFpbA=="}'
+
+# Expected: Both operations succeed
+```
+
+### 2.3 Data Consistency Check
+
+```bash
+# Read all keys from surviving nodes - should match
+grpcurl -plaintext localhost:5001 flaredb.kv.KvRaw/RawScan \
+  -d '{"start_key":"","end_key":"//8=","limit":100}'
+
+grpcurl -plaintext localhost:5003 flaredb.kv.KvRaw/RawScan \
+  -d '{"start_key":"","end_key":"//8=","limit":100}'
+
+# Expected: Identical results (no data loss)
+```
+
+---
+
+## Test 3: Quorum Loss (2 of 3 Nodes Down)
+
+### 3.1 Kill Second Node
+
+```bash
+# With node-2 already down, kill node-3
+kill -9 $(pgrep -f "chainfire-server.*2383")
+
+# Attempt write
+grpcurl -plaintext localhost:2379 chainfire.api.Kv/Put \
+  -d '{"key":"bm8tcXVvcnVt","value":"c2hvdWxkLWZhaWw="}'
+
+# Expected: Timeout or error (no quorum)
+# Error message should indicate cluster unavailable
+```
+
+### 3.2 Graceful Degradation
+
+```bash
+# Verify reads still work (from local Raft log)
+grpcurl -plaintext localhost:2379 chainfire.api.Kv/Get \
+  -d '{"key":"dGVzdA=="}'
+
+# Expected: Read succeeds (stale read allowed)
+# OR: Read fails with clear "no quorum" error
+```
+
+### 3.3 Recovery
+
+```bash
+# Restart node-3
+./chainfire-server --config /tmp/t040/chainfire-3/config.toml &
+
+# Wait for quorum restoration
+# Retry write
+grpcurl -plaintext localhost:2379 chainfire.api.Kv/Put \
+  -d '{"key":"cmVjb3ZlcmVk","value":"c3VjY2Vzcw=="}'
+
+# Expected: Write succeeds, cluster operational
+```
+
+---
+
+## Test 4: Process Pause (Simulated Freeze)
+
+```bash
+# Pause leader process
+kill -STOP $(pgrep -f "chainfire-server.*2379")
+
+# Wait for heartbeat timeout (typically 1-5 seconds)
+sleep 10
+
+# Verify new leader elected
+grpcurl -plaintext localhost:2381 chainfire.api.Cluster/GetLeader
+
+# Resume paused process
+kill -CONT $(pgrep -f "chainfire-server.*2379")
+
+# Verify old leader rejoins as follower
+# (check logs for "became follower" message)
+```
+
+---
+
+## Evidence Collection
+
+For each test, record:
+1. **Timestamps**: When failure injected, when detected, when recovered
+2. **Leader transitions**: Old leader ID → New leader ID
+3. **Data verification**: Keys written during failure, confirmed after recovery
+4. **Error messages**: Exact error returned during quorum loss
+
+### Log Snippets to Capture
+
+```bash
+# ChainFire leader election
+grep -i "leader\|election\|became" /tmp/t040/chainfire-*/logs/*
+
+# FlareDB Raft state
+grep -i "raft\|leader\|commit" /tmp/t040/flaredb-*/logs/*
+```
+
+---
+
+## Success Criteria
+
+| Test | Expected | Pass/Fail |
+|------|----------|-----------|
+| 1.1 Leader kill | Cluster continues, new leader in <10s | |
+| 1.2 Leader election | Correct leader ID returned | |
+| 1.3 Node rejoin | Cluster returns to 3/3 | |
+| 2.1-2.3 FlareDB quorum | Writes succeed with 2/3, data consistent | |
+| 3.1-3.3 Quorum loss | Graceful error, recovery works | |
+| 4 Process pause | Leader election on timeout, old node rejoins | |
+
+---
+
+## Known Gaps (Document, Don't Block)
+
+1. **Cross-network partition**: Not tested (requires iptables/network namespace)
+2. **Disk failure**: Not simulated
+3. **Clock skew**: Not tested
+
+These are deferred to T039 (production deployment) or future work.

+# T040.S3 PlasmaVMC HA Behavior Runbook
+
+## Objective
+Document PlasmaVMC behavior when host fails. This is a **gap documentation** exercise - live migration is NOT implemented.
+
+## Current Capability Assessment
+
+### What IS Implemented
+| Feature | Status | Location |
+|---------|--------|----------|
+| VM State tracking | YES | `plasmavmc-types/src/vm.rs:56` - VmState::Migrating |
+| KVM capability flag | YES | `plasmavmc-kvm/src/lib.rs:147` - `live_migration: true` |
+| QMP state parsing | YES | `plasmavmc-kvm/src/qmp.rs:99` - parses "inmigrate"/"postmigrate" |
+| ChainFire persistence | YES | VM metadata stored in cluster KVS |
+
+### What is NOT Implemented (GAPS)
+| Feature | Gap | Impact |
+|---------|-----|--------|
+| Live migration API | No `migrate()` function | VMs cannot move between hosts |
+| Host failure detection | No health monitoring | VM loss undetected |
+| Automatic recovery | No failover logic | Manual intervention required |
+| Shared storage | No VM disk migration | Would need shared storage (Ceph/NFS) |
+
+---
+
+## Test Scenarios
+
+### Scenario 1: Document Current VM Lifecycle
+
+```bash
+# Create a VM
+grpcurl -plaintext localhost:50051 plasmavmc.VmService/CreateVm \
+  -d '{"name":"test-vm","vcpus":1,"memory_mb":512}'
+
+# Get VM ID from response
+VM_ID="<returned-id>"
+
+# Check VM state
+grpcurl -plaintext localhost:50051 plasmavmc.VmService/GetVm \
+  -d "{\"id\":\"$VM_ID\"}"
+
+# Expected: VM running on this host
+```
+
+### Scenario 2: Host Process Kill (Simulated Failure)
+
+```bash
+# Kill PlasmaVMC server
+kill -9 $(pgrep -f plasmavmc-server)
+
+# QEMU processes continue running (orphaned)
+ps aux | grep qemu
+
+# Expected Behavior:
+# - QEMU continues (not managed)
+# - VM metadata in ChainFire still shows "Running"
+# - No automatic recovery
+```
+
+### Scenario 3: Restart PlasmaVMC Server
+
+```bash
+# Restart server
+./plasmavmc-server &
+
+# Check if VM is rediscovered
+grpcurl -plaintext localhost:50051 plasmavmc.VmService/ListVms
+
+# Expected Behavior (DOCUMENT):
+# Option A: Server reads ChainFire, finds orphan, reconnects QMP
+# Option B: Server reads ChainFire, state mismatch (metadata vs reality)
+# Option C: Server starts fresh, VMs lost from management
+```
+
+### Scenario 4: QEMU Process Kill (VM Crash)
+
+```bash
+# Kill QEMU directly
+kill -9 $(pgrep -f "qemu.*$VM_ID")
+
+# Check PlasmaVMC state
+grpcurl -plaintext localhost:50051 plasmavmc.VmService/GetVm \
+  -d "{\"id\":\"$VM_ID\"}"
+
+# Expected:
+# - State should transition to "Failed" or "Unknown"
+# - (Or) State stale until next QMP poll
+```
+
+---
+
+## Documentation Template
+
+After testing, fill in this table:
+
+| Failure Mode | Detection Time | Automatic Recovery? | Manual Steps Required |
+|--------------|----------------|--------------------|-----------------------|
+| PlasmaVMC server crash | N/A | NO | Restart server, reconcile state |
+| QEMU process crash | ? seconds | NO | Delete/recreate VM |
+| Host reboot | N/A | NO | VMs lost, recreate from metadata |
+| Network partition | N/A | NO | No detection mechanism |
+
+---
+
+## Recommendations for Future Work
+
+Based on test findings, document gaps for future implementation:
+
+1. **Host Health Monitoring**
+   - PlasmaVMC servers should heartbeat to ChainFire
+   - Other nodes detect failure via missed heartbeats
+   - Estimated effort: Medium
+
+2. **VM State Reconciliation**
+   - On startup, scan running QEMUs, match to ChainFire metadata
+   - Handle orphans and stale entries
+   - Estimated effort: Medium
+
+3. **Live Migration (Full)**
+   - Requires: shared storage, QMP migrate command, network coordination
+   - Estimated effort: Large (weeks)
+
+4. **Cold Migration (Simpler)**
+   - Stop VM, copy disk, start on new host
+   - More feasible short-term
+   - Estimated effort: Medium
+
+---
+
+## Success Criteria for S3
+
+| Criterion | Status |
+|-----------|--------|
+| Current HA capabilities documented | |
+| Failure modes tested and recorded | |
+| Recovery procedures documented | |
+| Gap list with priorities created | |
+| No false claims about live migration | |
+
+---
+
+## Notes
+
+This runbook is intentionally about **documenting current behavior**, not testing features that don't exist. The value is in:
+1. Clarifying what works today
+2. Identifying gaps for production readiness
+3. Informing T039 (production deployment) requirements

+# T040.S4 Service Reconnection Test Scenarios
+
+## Overview
+Test scenarios for validating service reconnection behavior after transient failures.
+
+## Test Environment: Option B2 (Local Multi-Instance)
+**Approved**: 2025-12-11
+
+**Setup**: 3 instances per service running on localhost with different ports
+- ChainFire: ports 2379, 2380, 2381 (or similar)
+- FlareDB: ports 5000, 5001, 5002 (or similar)
+
+**Failure Simulation Methods** (adapted from VM approach):
+- **Process kill**: `kill -9 <pid>` simulates sudden node failure
+- **SIGTERM**: `kill <pid>` simulates graceful shutdown
+- **Port blocking**: `iptables -A INPUT -p tcp --dport <port> -j DROP` (if root)
+- **Pause**: `kill -STOP <pid>` / `kill -CONT <pid>` simulates freeze
+
+**Note**: Cross-VM network partition tests deferred to T039 (production deployment)
+
+## Current State Analysis
+
+### Services WITH Reconnection Logic
+| Service | Mechanism | Location |
+|---------|-----------|----------|
+| ChainFire | Exponential backoff (3 retries, 2.0x multiplier, 500ms-30s) | `chainfire/crates/chainfire-api/src/raft_client.rs` |
+| FlareDB | PD client auto-reconnect (10s cycle), connection pooling | `flaredb/crates/flaredb-server/src/main.rs:283-356` |
+
+### Services WITHOUT Reconnection Logic (GAPS)
+| Service | Gap | Risk |
+|---------|-----|------|
+| PlasmaVMC | No retry/reconnection | VM operations fail silently on network blip |
+| IAM | No retry mechanism | Auth failures cascade to all services |
+| Watch streams | Break on error, no auto-reconnect | Config/event propagation stops |
+
+---
+
+## Test Scenarios
+
+### Scenario 1: ChainFire Raft Recovery
+**Goal**: Verify Raft RPC retry logic works under network failures
+
+**Steps**:
+1. Start 3-node ChainFire cluster
+2. Write key-value pair
+3. Use `iptables` to block traffic to leader node
+4. Attempt read/write operation from client
+5. Observe retry behavior (should retry with backoff)
+6. Unblock traffic
+7. Verify operation completes or fails gracefully
+
+**Expected**:
+- Client retries up to 3 times with exponential backoff
+- Clear error message on final failure
+- No data corruption
+
+**Evidence**: Client logs showing retry attempts, timing
+
+---
+
+### Scenario 2: FlareDB PD Reconnection
+**Goal**: Verify FlareDB server reconnects to ChainFire (PD) after restart
+
+**Steps**:
+1. Start ChainFire cluster (PD)
+2. Start FlareDB server connected to PD
+3. Verify heartbeat working (check logs)
+4. Kill ChainFire leader
+5. Wait for new leader election
+6. Observe FlareDB reconnection behavior
+
+**Expected**:
+- FlareDB logs "Reconnected to PD" within 10-20s
+- Client operations resume after reconnection
+- No data loss during transition
+
+**Evidence**: Server logs, client operation success
+
+---
+
+### Scenario 3: Network Partition (iptables)
+**Goal**: Verify cluster behavior during network partition
+
+**Steps**:
+1. Start 3-node cluster (ChainFire + FlareDB)
+2. Write data to cluster
+3. Create network partition: `iptables -A INPUT -s <node2-ip> -j DROP`
+4. Attempt writes (should succeed with 2/3 quorum)
+5. Kill another node (should lose quorum)
+6. Verify writes fail gracefully
+7. Restore partition, verify cluster recovery
+
+**Expected**:
+- 2/3 nodes: writes succeed
+- 1/3 nodes: writes fail, no data corruption
+- Recovery: cluster resumes normal operation
+
+**Evidence**: Write success/failure, data consistency check
+
+---
+
+### Scenario 4: Service Restart Recovery
+**Goal**: Verify clients reconnect after service restart
+
+**Steps**:
+1. Start service (FlareDB/ChainFire)
+2. Connect client
+3. Perform operations
+4. Restart service (`systemctl restart` or SIGTERM + start)
+5. Attempt client operations
+
+**Expected ChainFire**: Client reconnects via retry logic
+**Expected FlareDB**: Connection pool creates new connection
+**Expected IAM**: Manual reconnect required (gap)
+
+**Evidence**: Client operation success after restart
+
+---
+
+### Scenario 5: Watch Stream Recovery (GAP DOCUMENTATION)
+**Goal**: Document watch stream behavior on connection loss
+
+**Steps**:
+1. Start ChainFire server
+2. Connect watch client
+3. Verify events received
+4. Kill server
+5. Observe client behavior
+
+**Expected**: Watch breaks, no auto-reconnect
+**GAP**: Need application-level reconnect loop
+
+**Evidence**: Client logs showing stream termination
+
+---
+
+## Test Matrix
+
+| Scenario | ChainFire | FlareDB | PlasmaVMC | IAM |
+|----------|-----------|---------|-----------|-----|
+| S1: Raft Recovery | TEST | n/a | n/a | n/a |
+| S2: PD Reconnect | n/a | TEST | n/a | n/a |
+| S3: Network Partition | TEST | TEST | SKIP | SKIP |
+| S4: Restart Recovery | TEST | TEST | DOC-GAP | DOC-GAP |
+| S5: Watch Recovery | DOC-GAP | DOC-GAP | n/a | n/a |
+
+---
+
+## Prerequisites (Option B2 - Local Multi-Instance)
+- 3 ChainFire instances running on localhost (S1 provides)
+- 3 FlareDB instances running on localhost (S1 provides)
+- Separate data directories per instance
+- Logging enabled at DEBUG level for evidence
+- Process management tools (kill, pkill)
+- Optional: iptables for port blocking tests (requires root)
+
+## Success Criteria
+- All TEST scenarios pass
+- GAP scenarios documented with recommendations
+- No data loss in any failure scenario
+- Clear error messages on unrecoverable failures
+
+## Future Work (Identified Gaps)
+1. PlasmaVMC: Add retry logic for remote service calls
+2. IAM Client: Add exponential backoff retry
+3. Watch streams: Add auto-reconnect wrapper

+
+  No bare-metal hardware available yet. Focus on HA validation using VMs.
+
+  **Key Questions to Answer:**
+  1. Does PlasmaVMC properly migrate VMs when a host node dies?
+  2. Does ChainFire Raft cluster maintain quorum during node failures?
+  3. Does FlareDB Raft cluster maintain consistency during failures?
+  4. Do services automatically reconnect/recover after transient failures?

+      - ChainFire built via nix develop (~2 min)
+      - FlareDB built via nix develop (~2 min)
+
+      **Step 2: Single-Node Test** ✓
+      - test_single_node_kv_operations PASSED
+      - Leader election works (term=1)
+      - KV operations (put/get/delete) work
+
+      **Step 3: 3-Node Cluster** BLOCKED
+      - test_3node_leader_election_with_join HANGS at member_add
+      - Node 1 bootstraps and becomes leader successfully
+      - Node 2/3 start but join flow times out (>120s)
+      - Hang location: cluster_service.rs:87 `raft.add_learner(member_id, node, true)`
+      - add_learner with blocking=true waits for learner catch-up indefinitely
+
+      **Root Cause Analysis:**
+      - The openraft add_learner with blocking=true waits for new node to catch up
+      - RPC client has address registered before add_learner call
+      - Likely issue: learner node not responding to AppendEntries RPC
+      - Needs investigation in chainfire-api/raft_client.rs network layer
+
+      **Decision Needed:**
+      A) Fix member_add bug (scope creep)
+      B) Document as blocker, create new task
+      C) Use single-node for S2 partial testing

+
+## Bug: Assertion failure `upto >= log_id_range.prev` during learner replication
+
+### Version
+- openraft: 0.9.21
+- Rust: 1.91.1
+- OS: Linux
+
+### Description
+
+When adding a learner to a single-node Raft cluster and attempting to replicate logs, OpenRaft panics with an assertion failure in debug builds. In release builds, the assertion is skipped but the replication hangs indefinitely.
+
+### Assertion Location
+```
+openraft-0.9.21/src/progress/inflight/mod.rs:178
+assertion failed: upto >= log_id_range.prev
+```
+
+### Reproduction Steps
+
+1. Bootstrap a single-node cluster (node 1)
+2. Start a second node configured as a learner (not bootstrapped)
+3. Call `add_learner(node_id=2, node=BasicNode::default(), blocking=true)` from the leader
+4. The add_learner succeeds
+5. During subsequent replication/heartbeat to the learner, panic occurs
+
+### Minimal Reproduction Code
+
+```rust
+// Leader node (bootstrapped)
+let raft = Raft::new(1, config, network, log_store, sm).await?;
+raft.initialize(btreemap!{1 => BasicNode::default()}).await?;
+
+// Wait for leader election
+sleep(Duration::from_secs(2)).await;
+
+// Add learner (second node is running but not bootstrapped)
+raft.add_learner(2, BasicNode::default(), true).await?; // Succeeds
+
+// Panic occurs here during replication to learner
+// Either during add_learner's blocking wait or subsequent heartbeats
+```
+
+### Expected Behavior
+
+The learner should receive AppendEntries from the leader and catch up with the log without assertion failures.
+
+### Actual Behavior
+
+- **Debug build:** Panic with `assertion failed: upto >= log_id_range.prev`
+- **Release build:** No panic, but replication hangs indefinitely (suggests undefined behavior)
+
+### Feature Flags Tested
+
+- `loosen-follower-log-revert` - No effect on this assertion
+
+### Analysis
+
+The assertion `debug_assert!(upto >= log_id_range.prev)` in the `ack` method validates that acknowledgments are monotonically increasing within the replication window.
+
+The failure suggests that when a new learner is added, the progress tracking state may not be properly initialized, causing the first acknowledgment to violate this invariant.
+
+This appears related to (but different from) the fix in #584/#585, which addressed `value > prev` in `progress/mod.rs`. This assertion is in `progress/inflight/mod.rs`.
+
+### Environment
+
+```toml
+[dependencies]
+openraft = { version = "0.9", features = ["serde", "storage-v2", "loosen-follower-log-revert"] }
+```
+
+### Additional Context
+
+- Single-node to multi-node cluster expansion via dynamic membership
+- Learner node has empty log state (never bootstrapped)
+- Leader is already initialized with some log entries

+# Option C: Snapshot Pre-seed Workaround
+
+## Problem
+OpenRaft 0.9.21 has a bug where the assertion `upto >= log_id_range.prev` fails in `progress/inflight/mod.rs:178` during learner replication. This occurs when:
+1. A learner is added to a cluster with `add_learner()`
+2. The leader's progress tracking state becomes inconsistent during initial log replication
+
+## Root Cause Analysis
+When a new learner joins, it has empty log state. The leader must replicate all logs from the beginning. During this catch-up phase, OpenRaft's progress tracking can become inconsistent when:
+- Replication streams are re-spawned
+- Progress reverts to zero
+- The `upto >= log_id_range.prev` invariant is violated
+
+## Workaround Approach: Snapshot Pre-seed
+
+Instead of relying on OpenRaft's log replication to catch up the learner, we pre-seed the learner with a snapshot before adding it to the cluster.
+
+### How It Works
+
+1. **Leader exports snapshot:**
+   ```rust
+   // On leader node
+   let snapshot = raft_storage.get_current_snapshot().await?;
+   let bytes = snapshot.snapshot.into_inner(); // Vec<u8>
+   ```
+
+2. **Transfer snapshot to learner:**
+   - Via file copy (manual)
+   - Via new gRPC API endpoint (automated)
+
+3. **Learner imports snapshot:**
+   ```rust
+   // On learner node, before starting Raft
+   let snapshot = Snapshot::from_bytes(&bytes)?;
+   snapshot_builder.apply(&snapshot)?;
+
+   // Also set log state to match snapshot
+   log_storage.purge(snapshot.meta.last_log_index)?;
+   ```
+
+4. **Add pre-seeded learner:**
+   - Learner already has state at `last_log_index`
+   - Only recent entries (since snapshot) need replication
+   - Minimal replication window avoids the bug
+
+### Implementation Options
+
+#### Option C1: Manual Data Directory Copy
+- Copy leader's `data_dir/` to learner before starting
+- Simplest, but requires manual intervention
+- Good for initial cluster setup
+
+#### Option C2: New ClusterService API
+```protobuf
+service ClusterService {
+    // Existing
+    rpc AddMember(AddMemberRequest) returns (AddMemberResponse);
+
+    // New
+    rpc TransferSnapshot(TransferSnapshotRequest) returns (stream TransferSnapshotResponse);
+}
+
+message TransferSnapshotRequest {
+    uint64 target_node_id = 1;
+    string target_addr = 2;
+}
+
+message TransferSnapshotResponse {
+    bytes chunk = 1;
+    bool done = 2;
+    SnapshotMeta meta = 3; // Only in first chunk
+}
+```
+
+Modified join flow:
+1. `ClusterService::add_member()` first calls `TransferSnapshot()` to pre-seed
+2. Waits for learner to apply snapshot
+3. Then calls `add_learner()`
+
+#### Option C3: Bootstrap from Snapshot
+Add config option `bootstrap_from = "node_id"`:
+- Node fetches snapshot from specified node on startup
+- Applies it before joining cluster
+- Then waits for `add_learner()` call
+
+### Recommended Approach: C2 (API-based)
+
+**Pros:**
+- Automated, no manual intervention
+- Works with dynamic cluster expansion
+- Fits existing gRPC architecture
+
+**Cons:**
+- More code to implement (~200-300L)
+- Snapshot transfer adds latency to join
+
+### Files to Modify
+
+1. `chainfire/proto/cluster.proto` - Add TransferSnapshot RPC
+2. `chainfire-api/src/cluster_service.rs` - Implement snapshot transfer
+3. `chainfire-api/src/cluster_service.rs` - Modify add_member flow
+4. `chainfire-storage/src/snapshot.rs` - Expose snapshot APIs
+
+### Test Plan
+
+1. Start single-node cluster
+2. Write some data (create entries in log)
+3. Start second node
+4. Call add_member() - should trigger snapshot transfer
+5. Verify second node receives data
+6. Verify no assertion failures
+
+### Estimated Effort
+- Implementation: 3-4 hours
+- Testing: 1-2 hours
+- Total: 4-6 hours
+
+### Status
+- [x] Research complete
+- [ ] Awaiting 24h timer for upstream OpenRaft response
+- [ ] Implementation (if needed)

+  **Discovered during T040.S1 HA Test Environment Setup**
+
+  member_add API hangs when adding nodes to existing cluster.
+  Test: test_3node_leader_election_with_join hangs at add_learner call.
+
+  **Root Cause Analysis (PeerA 2025-12-11 - UPDATED):**
+  TWO independent issues identified:
+
+  **Issue 1: Timing Race (cluster_service.rs:89-105)**
+  1. Line 89: `add_learner(blocking=false)` returns immediately
+  2. Line 105: `change_membership(members)` called immediately after
+  3. Learner hasn't received any AppendEntries yet (no time to catch up)
+  4. change_membership requires quorum including learner → hangs
+
+  **Issue 2: Non-Bootstrap Initialization (node.rs:186-194)**
+  1. Nodes with bootstrap=false + role=Voter hit `_ =>` case
+  2. They just log "Not bootstrapping" and do nothing
+  3. Raft instance exists but may not respond to AppendEntries properly
+
+  **S1 Diagnostic Decision Tree:**
+  - If "AppendEntries request received" log appears → Issue 1 (timing)
+  - If NOT received → Issue 2 (init) or network problem
+
+  **Key Files:**
+  - chainfire/crates/chainfire-api/src/cluster_service.rs:89-105 (timing issue)
+  - chainfire/crates/chainfire-server/src/node.rs:186-194 (init issue)
+  - chainfire/crates/chainfire-api/src/internal_service.rs:83-88 (diagnostic logging)

+      **STATUS: BLOCKED by OpenRaft 0.9.21 bug**
+
+      Test fails with: `assertion failed: upto >= log_id_range.prev`
+      Location: openraft-0.9.21/src/progress/inflight/mod.rs:178
+
+      **Investigation (2025-12-11):**
+      1. Bug manifests in two scenarios:
+         - During `change_membership` (learner->voter promotion)
+         - During regular log replication to learners
+      2. Timing delays (500ms->2s) do not help
+      3. `role=Learner` config for non-bootstrap nodes does not help
+      4. `loosen-follower-log-revert` feature flag does not help
+      5. OpenRaft 0.9.16 "fix" does not address this specific assertion
+
+      **Root Cause:**
+      OpenRaft's replication progress tracking has inconsistent state when
+      managing learners. The assertion checks `upto >= log_id_range.prev`
+      but progress can revert to zero when replication streams re-spawn.
+
+      **Recommended Fix:**
+      - Option A: Upgrade to OpenRaft 0.10.x (breaking API changes) - NOT VIABLE (alpha only)
+      - Option B: File OpenRaft issue for 0.9.x patch - APPROVED

+      - 0.9.0-0.9.5: API incompatible (macro signature changed)
+      - 0.8.9: Major API incompatible (different traits, macros)
+
+      **Key Finding:**
+      Bug occurs during ANY replication to learners, not just promotion:
+      - add_learner succeeds
+      - Next operation (put, etc.) triggers assertion failure
+      - Learner-only cluster (no voter promotion) still crashes
+
+      **Workarounds Tried (ALL FAILED):**
+      1. Extended delays (2s → 10s)
+      2. Direct voter addition (OpenRaft forbids)
+      3. Simultaneous bootstrap (election split-vote)
+      4. Learner-only cluster (crashes on replication)
+
+      **Options Presented to User:**
+      1. 0.8.x API migration (~3-5 days)
+      2. Alternative Raft lib (~1-2 weeks)

+      **Investigation (2025-12-11 19:50-20:10 JST):**
+      Per user request for deeper investigation.
+
+      **Assertion Location (openraft-0.9.21/src/progress/inflight/mod.rs:178):**
+      ```rust
+      Inflight::Logs { id, log_id_range } => {
+          debug_assert!(upto >= log_id_range.prev);  // LINE 178 - FAILS HERE
+          debug_assert!(upto <= log_id_range.last);
+          Inflight::logs(upto, log_id_range.last.clone()).with_id(*id)
+      }
+      ```
+
+      **Call Chain:**
+      1. ReplicationHandler::update_matching() - receives follower response
+      2. ProgressEntry::update_matching(request_id, matching)
+      3. Inflight::ack(request_id, matching) - assertion fails
+
+      **Variables:**
+      - `upto`: Log ID that follower/learner acknowledges as matching
+      - `log_id_range.prev`: Start of the log range leader sent
+
+      **Root Cause:**
+      During `change_membership()` (learner->voter promotion):
+      1. `rebuild_progresses()` calls `upgrade_quorum_set()` with `default_v = ProgressEntry::empty(end)`
+      2. `rebuild_replication_streams()` resets `inflight = None` but preserves `curr_inflight_id`
+      3. New stream's `next_send()` calculates `log_id_range` using `calc_mid(matching_next, searching_end)`
+      4. Race condition: calculated `log_id_range.prev` can exceed the actual learner state
+
+      **Related Fix (PR #585):**
+      - Fixed "progress reverts to zero when re-spawning replications"
+      - Did NOT fix this specific assertion failure scenario
+
+      **Why loosen-follower-log-revert doesn't help:**
+      - Feature only affects `update_conflicting()`, not `ack()` assertion
+      - The assertion in `ack()` has no feature flag protection
+
+      **Confirmed Bug Trigger:**
+      - Crash occurs during voter promotion (`change_membership`)
+      - The binary search calculation in `calc_mid()` can produce a `start` index
+        higher than what the learner actually has committed
+      - When learner responds with its actual (lower) matching, assertion fails

+    owner: peerB
+    priority: P0
+    notes: |
+      **User Decision (2025-12-11 20:25 JST):**
+      OpenRaftのバグが解決困難なため、自前Raft実装を決定。
+
+      **方針:** Option B - ChainFire/FlareDB別々実装
+      - ChainFire: 単一Raftグループ用シンプル実装
+      - FlareDB: Multi-Raftは後日別途検討
+
+      **実装フェーズ:**
+      - P1: Leader Election (RequestVote) - 2-3日
+      - P2: Log Replication (AppendEntries) - 3-4日
+      - P3: Commitment & State Machine - 2日
+      - P4: Membership Changes - 後回し可
+      - P5: Snapshotting - 後回し可
+
+      **再利用資産:**
+      - chainfire-storage/ (RocksDB永続化)
+      - chainfire-proto/ (gRPC定義)
+      - chainfire-raft/network.rs (RPC通信層)
+
+      **実装場所:** chainfire-raft/src/core.rs
+      **Feature Flag:** 既存OpenRaftと切り替え可能に
+
+      **Progress (2025-12-11 21:28 JST):**
+      - core.rs: 776行 ✓
+      - tests/leader_election.rs: 168行 (NEW)

+# T046: OpenRaft-Style Multi-Raft Core Library
+
+## 設計方針
+
+OpenRaft風のtick-driven設計で、Multi-Raft対応を最初から組み込む。
+
+**Key Principles:**
+1. **Tick-driven**: 内部タイマー無し、外部からtick()で時間を進める
+2. **Ready pattern**: I/Oを実行せず、「やるべきこと」をReady構造体で返す
+3. **Multi-Raft Native**: 複数グループの効率的管理が設計に組み込まれている
+4. **Pure Logic**: Raftコアは純粋ロジック、テストが容易
+
+## アーキテクチャ

+## Core API
+
+### RaftCore (純粋Raftロジック)
+
+```rust
+/// Pure Raft state machine - no I/O, no async
+pub struct RaftCore<S: Storage> {
+    id: NodeId,
+    // Persistent state
+    current_term: u64,
+    voted_for: Option<NodeId>,
+    log: Vec<LogEntry>,
+    // Volatile state
+    commit_index: u64,
+    last_applied: u64,
+    role: Role,
+    // Leader state
+    next_index: HashMap<NodeId, u64>,
+    match_index: HashMap<NodeId, u64>,
+    // Timing (tick counts, not wall clock)
+    election_elapsed: u64,
+    heartbeat_elapsed: u64,
+    // Storage abstraction
+    storage: S,
+}
+
+impl<S: Storage> RaftCore<S> {
+    /// Create new Raft instance
+    pub fn new(id: NodeId, peers: Vec<NodeId>, storage: S) -> Self;
+
+    /// Advance logical time by one tick
+    /// Returns Ready with actions to take (election, heartbeat, etc.)
+    pub fn tick(&mut self) -> Ready;
+
+    /// Process incoming Raft message
+    pub fn step(&mut self, msg: Message) -> Ready;
+
+    /// Propose new entry (leader only)
+    pub fn propose(&mut self, data: Vec<u8>) -> Result<Ready, NotLeader>;
+
+    /// Notify that Ready actions have been processed
+    pub fn advance(&mut self, applied: Applied);
+
+    /// Check if this node is leader
+    pub fn is_leader(&self) -> bool;
+
+    /// Get current leader (if known)
+    pub fn leader(&self) -> Option<NodeId>;
+}
+```
+
+### Ready (出力アクション)
+
+```rust
+/// Actions to be executed by the caller (I/O layer)
+#[derive(Default)]
+pub struct Ready {
+    /// Messages to send to other nodes
+    pub messages: Vec<(NodeId, Message)>,
+
+    /// Entries to append to log storage
+    pub entries_to_persist: Vec<LogEntry>,
+
+    /// Hard state to persist (term, voted_for)
+    pub hard_state: Option<HardState>,
+
+    /// Committed entries ready to apply to state machine
+    pub committed_entries: Vec<LogEntry>,
+
+    /// Snapshot to install (if any)
+    pub snapshot: Option<Snapshot>,
+
+    /// Soft state changes (leader, role) - for notification only
+    pub soft_state: Option<SoftState>,
+}
+
+impl Ready {
+    /// Check if there are any actions to take
+    pub fn is_empty(&self) -> bool;
+
+    /// Merge another Ready into this one
+    pub fn merge(&mut self, other: Ready);
+}
+```
+
+### Storage Trait
+
+```rust
+/// Storage abstraction - caller provides implementation
+pub trait Storage {
+    /// Get persisted hard state
+    fn hard_state(&self) -> HardState;
+
+    /// Get log entries in range [start, end)
+    fn entries(&self, start: u64, end: u64) -> Vec<LogEntry>;
+
+    /// Get term at given index (None if not exists)
+    fn term(&self, index: u64) -> Option<u64>;
+
+    /// Get last log index
+    fn last_index(&self) -> u64;
+
+    /// Get first log index (after compaction)
+    fn first_index(&self) -> u64;
+
+    /// Get snapshot metadata (if any)
+    fn snapshot(&self) -> Option<SnapshotMeta>;
+}
+```
+
+### Message Types
+
+```rust
+pub enum Message {
+    RequestVote(RequestVoteRequest),
+    RequestVoteResponse(RequestVoteResponse),
+    AppendEntries(AppendEntriesRequest),
+    AppendEntriesResponse(AppendEntriesResponse),
+    InstallSnapshot(InstallSnapshotRequest),
+    InstallSnapshotResponse(InstallSnapshotResponse),
+}
+```
+
+## Multi-Raft Coordinator
+
+```rust
+/// Manages multiple Raft groups efficiently
+pub struct MultiRaft<S: Storage> {
+    node_id: NodeId,
+    groups: HashMap<GroupId, RaftCore<S>>,
+    storage_factory: Box<dyn Fn(GroupId) -> S>,
+}
+
+impl<S: Storage> MultiRaft<S> {
+    /// Tick all groups, return aggregated Ready
+    pub fn tick(&mut self) -> MultiReady {
+        let mut ready = MultiReady::default();
+        for (gid, core) in &mut self.groups {
+            let r = core.tick();
+            ready.merge(*gid, r);
+        }
+        ready
+    }
+
+    /// Route message to appropriate group
+    pub fn step(&mut self, gid: GroupId, msg: Message) -> Ready {
+        self.groups.get_mut(&gid)
+            .map(|c| c.step(msg))
+            .unwrap_or_default()
+    }
+
+    /// Propose to specific group
+    pub fn propose(&mut self, gid: GroupId, data: Vec<u8>) -> Result<Ready, Error>;
+
+    /// Create new group
+    pub fn create_group(&mut self, gid: GroupId, peers: Vec<NodeId>) -> Result<()>;
+
+    /// Remove group
+    pub fn remove_group(&mut self, gid: GroupId) -> Result<()>;
+}
+
+/// Aggregated Ready with message batching
+#[derive(Default)]
+pub struct MultiReady {
+    /// Messages batched by destination node
+    /// HashMap<NodeId, Vec<(GroupId, Message)>>
+    pub messages: HashMap<NodeId, Vec<(GroupId, Message)>>,
+
+    /// Per-group Ready (for storage operations)
+    pub groups: HashMap<GroupId, Ready>,
+}
+```
+
+## Single-Raft Wrapper (ChainFire用)
+
+```rust
+/// Async wrapper for single Raft group
+pub struct RaftNode {
+    core: RaftCore<RocksDbStorage>,
+    peers: HashMap<NodeId, PeerClient>,
+    tick_interval: Duration,
+    storage: Arc<RocksDB>,
+}
+
+impl RaftNode {
+    /// Start the Raft node (spawns tick loop)
+    pub async fn start(&mut self) {
+        let mut interval = tokio::time::interval(self.tick_interval);
+        loop {
+            tokio::select! {
+                _ = interval.tick() => {
+                    let ready = self.core.tick();
+                    self.process_ready(ready).await;
+                }
+                msg = self.receive_message() => {
+                    let ready = self.core.step(msg);
+                    self.process_ready(ready).await;
+                }
+            }
+        }
+    }
+
+    async fn process_ready(&mut self, ready: Ready) {
+        // 1. Persist entries and hard state
+        if let Some(hs) = &ready.hard_state {
+            self.storage.save_hard_state(hs)?;
+        }
+        self.storage.append_entries(&ready.entries_to_persist)?;
+
+        // 2. Send messages
+        for (to, msg) in ready.messages {
+            self.peers.get(&to)?.send(msg).await?;
+        }
+
+        // 3. Apply committed entries
+        for entry in ready.committed_entries {
+            self.state_machine.apply(entry)?;
+        }
+
+        // 4. Notify core
+        self.core.advance(Applied { ... });
+    }
+}

+## T041との比較
+
+| 観点 | T041 (現在) | T046 (新設計) |
+|------|-------------|---------------|
+| I/O | 統合 (直接実行) | 分離 (Ready返却) |
+| タイマー | 内部 (tokio::interval) | 外部 (tick count) |
+| async | 必須 | コアは不要 |
+| Multi-Raft | 別途ラッパー必要 | ネイティブ対応 |
+| テスト | async test必須 | sync test可能 |
+| コード量 | ~1,100 LOC | ~800 LOC (core) |
+
+## 実装計画
+
+| Phase | 内容 | 期間 |
+|-------|------|------|
+| P1 | Core Refactor (T041→tick-driven) | 1週間 |
+| P2 | Single-Raft Wrapper (ChainFire) | 3日 |
+| P3 | Multi-Raft Coordinator (FlareDB) | 1週間 |
+| P4 | Advanced (split/merge/cross-shard) | 将来 |
+
+**Total MVP:** 2.5週間
+
+## 次のアクション
+
+1. T041 P3完了 (統合テスト)
+2. T046 P1開始: core.rsからI/O削除、Ready pattern実装
+3. テスト: 純粋syncテストで動作確認

+owner: peerA
+created: 2025-12-11
+depends_on: [T041]
+blocks: []
+
+context: |
+  **Background:**
+  - T041: Custom Raft implementation (async/await, I/O integrated)
+  - Need: Unified Raft library for both ChainFire and FlareDB
+  - FlareDB requires Multi-Raft for sharding
+
+  **Design Direction (Updated):**
+  OpenRaft風のtick-driven設計で、Multi-Raft対応を最初から組み込む。
+  T041の実装をリファクタして、I/O分離・Ready pattern採用。
+
+  **Key Design Principles:**
+  1. **Tick-driven**: 外部からtick()を呼び、Ready構造体でアクションを返す
+  2. **I/O分離**: Raftコアは純粋ロジック、I/Oは呼び出し側が実行
+  3. **Multi-Raft Native**: 複数グループを効率的に管理可能な設計
+  4. **Single/Multi両対応**: ChainFire(single)もFlareDB(multi)も同じコアを使用
+
+acceptance:
+  - OpenRaft-style tick-driven API設計完了
+  - Ready pattern実装
+  - ChainFire/FlareDB両方で使用可能

+      3. **Multi-Raft efficient**: Batch messages, shared tick loop

+      **Phase 1: Core Refactor (1 week)**
+      - [ ] Extract pure Raft logic from T041 core.rs
+      - [ ] Implement Ready pattern (no direct I/O)
+      - [ ] Add Storage trait abstraction
+      - [ ] tick() / step() / propose() API
+
+      **Phase 2: Single-Raft Wrapper (3 days)**
+      - [ ] ChainFire RaftNode wrapper
+      - [ ] Async I/O integration (tokio)
+      - [ ] Timer management (election/heartbeat)
+      - [ ] Migrate ChainFire to new core
+
+      **Phase 3: Multi-Raft Coordinator (1 week)**
+      - [ ] MultiRaft struct with group management
+      - [ ] Message batching (MultiReady)
+      - [ ] Shared tick loop
+      - [ ] FlareDB integration
+
+      **Phase 4: Advanced (deferred)**
+      - [ ] Shard split/merge
+      - [ ] Cross-shard transactions
+      - [ ] Snapshot coordination
+
+      **Estimated Total:** 2.5 weeks for Phase 1-3

+      **Migration Strategy:**
+
+      1. **Complete T041 P3** (current)
+         - Finish integration tests
+         - Validate current impl works
+
+      2. **Extract & Refactor** (T046.P1)
+         - Copy T041 core.rs → raft-core/
+         - Remove async/I/O, add Ready pattern
+         - Keep original T041 as reference
+
+      3. **Parallel Operation** (T046.P2)
+         - Feature flag: `openraft-style` vs `legacy`
+         - Validate new impl matches old behavior
+
+      4. **Cutover** (T046.P3)
+         - Switch ChainFire to new core
+         - Remove legacy code
+
+      **Code Reuse from T041:**
+      - Election logic: ~200 LOC (RequestVote handling)
+      - Log replication: ~250 LOC (AppendEntries)
+      - Commit logic: ~150 LOC (advance_commit_index)
+      - Total reusable: ~600 LOC (refactor, not rewrite)

+  - type: architecture
+    date: 2025-12-11
+    finding: "Ready pattern + Storage trait + tick-driven API for unified Single/Multi Raft support"
+
+notes: |
+  **Key Insight:**
+  OpenRaft風のtick-driven設計により:
+  - 純粋なRaftロジックをテスト可能に (no async, no I/O)
+  - Multi-Raftのメッセージバッチ化が自然に実現
+  - ChainFire/FlareDB両方で同じコアを使用可能
+
+  **T041との関係:**
+  - T041: 現在のカスタムRaft実装 (動作確認用)
+  - T046: 本番用リファクタ (OpenRaft-style)
+  - T041完了後、T046でリファクタを開始

+    notes: |
+      **Architecture:**
+      - Dual API: gRPC (proto) + S3-compatible HTTP REST (Axum)
+      - S3 HTTP API: lightningstor/crates/lightningstor-server/src/s3/
+      - Native Rust implementation (no AWS SDK dependency)
+
+      **✓ IMPLEMENTED (7/8 core operations):**
+      - CreateBucket (router.rs:125-166)
+      - DeleteBucket (router.rs:168-195) - missing empty validation
+      - ListBuckets (router.rs:87-119)
+      - PutObject (router.rs:281-368) - missing x-amz-meta-* extraction
+      - GetObject (router.rs:370-427)
+      - DeleteObject (router.rs:429-476)
+      - HeadObject (router.rs:478-529)
+
+      **⚠️ GAPS BLOCKING AWS CLI COMPATIBILITY:**
+
+      CRITICAL:
+      1. ListObjectsV2 - Accepts list-type=2 but returns v1 format
+         - Need: KeyCount, proper continuation token, v2 XML schema
+      2. AWS Signature V4 - NO AUTH LAYER
+         - aws-cli will reject all requests without SigV4
+      3. Common Prefixes - Returns empty (TODO router.rs:262)
+         - Breaks hierarchical folder browsing
+
+      HIGH:
+      4. Multipart Uploads - All 6 operations unimplemented
+         - aws-cli uses for files >5MB
+      5. User Metadata (x-amz-meta-*) - Not extracted (TODO router.rs:332)
+
+      **Test Coverage:**
+      - gRPC: Well tested
+      - S3 HTTP: NO automated tests (manual curl only)
+
+      **Recommendation:**
+      Status: PARTIAL (7/8 basic ops, 0/3 critical features)

+    notes: |
+      **Implementation Files:**
+      1. lightningstor/crates/lightningstor-server/src/s3/auth.rs (NEW - 228L)
+      2. lightningstor/crates/lightningstor-server/src/s3/xml.rs (added ListBucketResultV2)
+      3. lightningstor/crates/lightningstor-server/src/s3/router.rs (enhanced list_objects, added compute_common_prefixes)
+      4. lightningstor/crates/lightningstor-server/src/s3/mod.rs (exported auth module)
+      5. lightningstor/crates/lightningstor-server/Cargo.toml (added hmac dependency)
+
+      **✓ COMPLETED (All 3 Critical Gaps from S1):**
+
+      1. **SigV4 Auth Middleware** (auth.rs):
+         - AWS4-HMAC-SHA256 signature verification
+         - Access key parsing from Authorization header
+         - IAM integration ready (currently uses dummy secret for MVP)
+         - Environment variable S3_AUTH_ENABLED for toggle
+         - Axum middleware applied to all routes
+         - Returns 403 SignatureDoesNotMatch on failure
+
+      2. **ListObjectsV2 Fix** (router.rs:276-322, xml.rs:83-114):
+         - Detects list-type=2 parameter
+         - Returns ListBucketResultV2 with proper schema
+         - Includes KeyCount, ContinuationToken, NextContinuationToken
+         - Backward compatible (v1 still supported)
+
+      3. **CommonPrefixes** (router.rs:237-279):
+         - Delimiter-based hierarchical browsing
+         - Groups objects by prefix (folder-like structure)
+         - Returns CommonPrefixes array for "subdirectories"
+         - Filters Contents to only show current-level objects
+         - Works with both v1 and v2 responses
+
+      **Compilation:** ✓ Success (warnings only, no errors)
+
+      **Remaining for AWS CLI Full Compatibility:**
+      - IAM credential endpoint (GetAccessKeySecret) - 2h
+      - Real SigV4 canonical request (currently simplified) - 4h
+      - Multipart upload support - 1 day (deferred, not critical for basic ops)

+      - aws s3 rm (DeleteObject) ✓
+      - aws s3 rb (DeleteBucket) ✓
+
+      **Route Refactor:**
+      - Implemented `dispatch_global` fallback router to handle `/{bucket}/{*key}` pattern
+      - Bypassed `matchit` routing limitations for complex S3 paths
+      - Manual path parsing handling root vs bucket vs object paths
+
+      **Auth Status:**
+      - SigV4 middleware active but signature validation fails (canonicalization mismatch)
+      - Functional tests passed with `S3_AUTH_ENABLED=false`
+      - Security: Auth is present but needs debugging for prod
