Summary

Paired draft docs: TableProApp/docs#169

• Add a downloadable macOS HydraDB driver with Cypher editing, native node and relationship browsing, scoped connections, supported property filters and export. Reuse the existing Bolt transport without changing PluginKit.
• Discover export property keys across the complete label or relationship type so properties beyond the 1,000-entity column sample are preserved. Reject unsupported grid operations and concurrent export schema changes explicitly.
• Requires the unreleased server compatibility change tracked in Support entity results and metadata discovery for Bolt database clients hydra-db/hydradb#297. Earlier HydraDB builds do not supply the entities and catalog needed by the browser. Grid edits, DDL, import, explicit transactions and cluster routing/failover are unavailable.

Test plan

• Real patched HydraDB server: Python compatibility assertions and 12 native production-driver checks pass, including two distinct parallel relationship identities and sparse export of 1,002 rows with a property beyond the column sample.
• Real Neo4j 5.26.0 regression probe passes, including export, error recovery and cancellation. Existing isolated graph-core tests: 45 passed in five suites.
• Project generation, touched Swift lint, plugin provides/registry checks and localization extraction pass. Supplemental unsigned HydraDB plugin build passes.
• Required plugin build fails because the official development signing certificate is unavailable. Required full package test command fails before running tests at an unchanged TabularSorter.swift compiler type-check error. These are unresolved failures, not passing checks.
• Supplemental unsigned AllPlugins build fails in unchanged RedisPluginConnection.swift because RedisReply does not conform to Sendable. The HydraDB bundle builds and dlopens; PluginKit duplication checks pass. This does not establish a full app build.
• Draft: GUI installation, HydraDB TLS/cancellation, file export round-trip, full app acceptance and cross-provider review remain pending. The configured Claude review profile is logged out. No merge or publication is requested.
