Research: Distributed KVS Consistency Modes (003-kvs-consistency)

Decisions

Consistency scope: Namespace-level selection of strong or eventual consistency.
- Rationale: Different tenants/workloads can choose per requirement.
- Alternatives considered: Cluster-wide only (too rigid).
Eventual consistency conflict resolution: Default LWW (last-write-wins); allow alternative policies via config.
- Rationale: Simple baseline with deterministic resolution; extensible for advanced policies.
- Alternatives considered: Version vectors/CRDT as default (more complex to operate by default).
