4c332c0972 Phase 1 (miroir-cdo): Core Routing enhancements and group fallback 
This commit includes enhancements to the Phase 1 Core Routing implementation:

merger.rs:
- Improve binary heap implementation with stable sorting
- Add descending_cmp helper method for consistent ordering
- Enhance tie-breaking by primary key for identical scores

search.rs:
- Add group fallback functionality for failed shards
- Refactor search_with_group for better testability
- Track failed shard IDs for targeted retry
- Add MAX_FALLBACK_ATTEMPTS to prevent cascading failures

scatter.rs:
- Update for consistency with new search flow

These enhancements build on the completed Phase 1 implementation:
- Router tests: 26/26 pass (rendezvous hashing, covering set)
- Merger tests: 15/15 pass (global sort, facets, offset/limit)
- Topology tests: 39/39 pass (node health state machine)
- Scatter tests: 7/7 pass (stub implementation)
- Coverage: router.rs (96.76%), topology.rs (100%), scatter.rs (100%), merger.rs (95.45%)

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)

fbc9a1a0c9 Phase 0 (miroir-qon): Verification complete - all DoD items met except musl toolchain 
## Verification Summary

- ✅ cargo build --all succeeds
- ✅ cargo test --all passes (126 tests)
- ✅ cargo clippy --all-targets --all-features -- -D warnings passes
- ✅ cargo fmt --all -- --check passes
- ✅ Config round-trips YAML → struct → YAML (test exists)
- ✅ No child beads exist (requirement satisfied)
- ⚠️ musl build blocked by missing x86_64-linux-musl-gcc toolchain (system dependency)

## Conclusion

Phase 0 foundation is complete. The project has a compilable workspace with all three crates, fully-typed Config struct, comprehensive test coverage, and style enforcement. The musl build failure is an environment/CI setup concern that will be addressed in Phase 8 (Deployment + CI).

3da0f9e43e Improve rendezvous hash seed and distribution assertions 
- Use seed=42 instead of 0 for better distribution properties while maintaining determinism
- Add documentation explaining the non-zero seed choice
- Add debug output for troubleshooting shard distribution
- Tighten DoD requirement assertions to 18-26 shards (more precise than 14-30)
