4c254883fd Phase 1 (miroir-cdo): Core Routing verification complete 
Complete Phase 1 Core Routing implementation with all DoD requirements met:

## Implementation Complete
- router.rs: Rendezvous hashing with XxHash64 (seed=0)
- topology.rs: Node health state machine with 7 states
- scatter.rs: Async fan-out orchestration trait
- merger.rs: Global sort, facet aggregation, offset/limit

## Test Results
- 87 Phase 1 tests pass (26 router + 15 merger + 7 scatter + 39 topology)
- All acceptance tests pass (determinism, reshuffle bounds, uniformity)
- Coverage exceeds 90% on all Phase 1 files

## Definition of Done ✅
- ✅ Rendezvous assignment is deterministic
- ✅ Adding 4th node moves at most ~50% of shards
- ✅ 64 shards/3 nodes/RF=1 → each node holds 15-27 shards
- ✅ Top-RF placement changes minimally on add/remove
- ✅ write_targets returns exactly RG × RF nodes
- ✅ query_group distributes evenly
- ✅ covering_set returns one node per shard
- ✅ Merger passes all merge/facet/limit tests
- ✅ Coverage ≥ 90% on all Phase 1 files

a046c3aff2 Phase 1 (miroir-cdo): Core Routing implementation complete 
Implements deterministic, coordination-free routing primitives that
everything else depends on. Any Miroir pod can independently compute
identical write targets and covering sets given a fixed topology.

Core routing (router.rs):
- score(): Rendezvous hashing with XxHash64 seed 0 (matches Meilisearch Enterprise)
- assign_shard_in_group(): HRW assignment with tie-breaking
- write_targets(): Returns exactly RG × RF nodes, one from each group
- query_group(): Round-robin query distribution across replica groups
- covering_set(): One node per shard with intra-group replica rotation
- shard_for_key(): Hash-based document-to-shard mapping

Topology management (topology.rs):
- NodeId, NodeStatus, Node, Group, Topology structs
- Node health state machine (Healthy/Degraded/Draining/Failed/Joining/Active/Removed)
- State transition validation
- Write eligibility logic (Draining nodes conditionally eligible)
- Healthy node filtering

Scatter primitives (scatter.rs):
- Scatter trait with StubScatter implementation
- ScatterRequest, ScatterResponse, NodeResponse structs

Result merger (merger.rs):
- Global sort by _rankingScore descending
- Offset/limit application after merge
- Facet count aggregation across shards
- Estimated total hits summation
- Conditional _rankingScore stripping
- Always strips _miroir_shard

Task registry (task.rs):
- TaskRegistry trait with StubTaskRegistry implementation
- MiroirTask, TaskStatus, NodeTask, NodeTaskStatus
- TaskFilter for listing

Acceptance tests (all passing):
- AT-1: Rendezvous determinism (1000 runs)
- AT-2: Reshuffle bound on add (2 × 1/4 × 64)
- AT-3: Reshuffle bound on remove (~RF × S / Ng)
- AT-4: Uniformity (64 shards, 3 nodes, RF=1 → 18–26 per node)
- AT-5: Top-RF placement stability
- AT-6: shard_for_key fixture verification
- AT-7: Tie-breaking on node_id
- AT-8: Canonical concatenation order (shard_id, node_id)

8535aa087c Phase 1 (miroir-cdo): Make Scatter trait async 
Update scatter.rs to use async_trait for async scatter execution.
This allows the scatter implementation to perform async I/O when
fanning out requests to nodes.

ad6bbb5af2 Phase 0 (miroir-qon): Close all child beads and complete Phase 0 
All 7 child beads (miroir-qon.1 through miroir-qon.7) verified complete:
- P0.1: Cargo workspace + toolchain pin (Rust 1.88)
- P0.2: miroir-core crate scaffolded (60 passing tests)
- P0.3: miroir-proxy crate scaffolded (axum HTTP server)
- P0.4: miroir-ctl crate scaffolded (clap CLI with credential loading)
- P0.5: Config struct mirroring plan §4 YAML schema
- P0.6: Repo hygiene (LICENSE, CHANGELOG, .gitignore)
- P0.7: CI smoke test (.github/workflows/test.yml)

Definition of Done status:
✓ cargo build --all succeeds
✓ cargo test --all succeeds (103 tests passing)
✓ cargo clippy --all-targets --all-features -- -D warnings passes
✓ cargo fmt --all -- --check passes
⚠ cargo build --release --target x86_64-unknown-linux-musl -p miroir-proxy fails (system dependency: x86_64-linux-musl-gcc not available on NixOS)
✓ Config round-trips YAML → struct → YAML

Foundation established for Phase 1 (routing logic).

783699b389 Phase 0 (miroir-qon): Fix openraft compilation issue on Rust 1.87 
- Remove openraft dependency (validit crate uses unstable let_chains)
- Comment out raft-proto module temporarily
- Fix benchmark targets: [[bin]] → [[bench]] to resolve duplicate target warnings
- Update Cargo.lock with dependency changes

This fixes the clippy --all-features build that was failing due to
openraft 0.9.22 not compiling on stable Rust 1.87.

Code improvements included:
- migration.rs: Fix in-flight write clearing to only affect migration shards
- score_comparability.rs: Add Serialize/Deserialize, clean up imports, formatting
- lib.rs: Alphabetize module declarations
- cutover_race.rs: Fix drain timeout test to fail writes on both old and new nodes

e47c1c2f73 P12.OP3: Validate 2× transient load caveat and add CLI schedule window guard 
- Add resharding load simulation model with real router hash functions
- Benchmark confirms storage amplification is exactly 2.0× and dual-write
  amplification is exactly 2.0× across all test matrix scenarios (1KB/10GB,
  10KB/100GB, 1MB/1TB), with hash distribution CV < 5% in all cases
- CLI window guard: resharding.allowed_windows config restricts resharding
  to named time windows (e.g. "02:00-06:00 UTC"), CLI refuses outside
  windows without --force
- Integration tests confirm rejection outside window, --force override,
  no-restriction mode, and disabled config handling
