Release v1.0.19 - UX + Fabric Routing + Maint. · orneryd/NornicDB

[1.0.19] - 2026-03-17

Cypher multi-statement browser execution UX: Added semicolon-delimited script execution in the Browser query pane with Cypher-aware splitting (strings/comments/backticks safe), stacked per-statement result panels, per-statement status/timing, and a continue-on-error toggle.
Infinigraph implementation guidance: Rewrote and expanded the Infinigraph topology user guide to target managed-service parity scenarios (not generic Fabric-only usage), including concrete architecture and implementation diagrams.

Per-database rerank override application: Search request paths now consistently use per-database reranker resolution across HTTP and Qdrant gRPC execution paths instead of relying on global-only rerank flags.
Reranker resolution model: Server startup now resolves effective per-DB rerank provider/model/API settings from DB config overrides with global fallback and cached external reranker instances.
Database UI metadata: /databases and related API/UI surfaces now expose and display search strategy details more consistently for operational visibility.

UNWIND create/execution hardening: Fixed execution-path edge handling in Cypher/Fabric integration where UNWIND-based create flows could diverge under composite/fabric routing branches.
Composite-only Fabric routing guardrails: Tightened routing so Fabric-specific execution paths are applied only where composite semantics require them, reducing misrouting and ambiguous behavior.

Storage package coverage push: Expanded real-assertion coverage across storage engines and helper paths to sustain 90%+ package coverage and lock regression-prone branches.
Cypher/Fabric regression expansion: Added and hardened deterministic tests around composite routing, UNWIND execution, and protocol-level parity paths.

Replaced generic topology guidance with a concrete Infinigraph parity implementation guide, including:
- control-plane/data-plane architecture diagram
- property contract diagram
- bounded cross-constituent query flow diagram
- shard split/rebalance sequence diagram
