feat(engine): introduce StorageBackend abstraction layer
feat(engine): introduce StorageBackend abstraction layer by Codex
Feb 5, 2026
Both PRs tackle the same goal — migrating Labels off HBaseTables onto the StorageBackend/StorageBucket abstraction — but take fundamentally different approaches.
#175 (Claude): Compatibility-first. Keeps DefaultHBaseCluster/HBaseTables as a bridge with a deprecated getTable(), leaves existing Label implementations intact, and passes all 431 engine tests.
This: Full cutover. Removes DefaultHBaseCluster/HBaseTables entirely and migrates Labels directly to StorageBuckets + MutationRequest. Cleaner end-state structurally, but only storage-scoped tests have been run — full engine test suite hasn't been validated yet.
The full cutover is where we want to end up eventually, but #175 is the right merge today: lower regression risk with full test coverage, and we can do the legacy cleanup as a follow-up once the new abstraction has proven stable in the broader codebase.
