docs(rfc): external EHDB driver MVP built + kind-validated (2026-07-10) 3 PRs open (ehdb#272, worker#180, ops#236). End-to-end kind validation: external pyarrow Flight SQL client read real projection rows from the dedicated endpoint; auth + read-only + fail-closed all enforced. Refs noetl/ai-meta#184
docs(rfc): external EHDB driver — decisions RESOLVED, status Accepted (MVP) All five forks resolved 2026-07-10 (recommended defaults accepted): Flight+Flight SQL, hybrid surface, dedicated data-plane endpoint fronting the worker, scoped read-only tokens (keychain/GSM), read-only committed-only MVP. Status → Accepted — implementing. Refs noetl/ai-meta#184
docs(rfc): external EHDB driver — outward-facing read access (design) Design-first RFC for an external driver/client so third-party apps and BI tools can read EHDB's engine tiers. Recommends Arrow Flight + Flight SQL over a dedicated data-plane endpoint fronting the worker (loose coupling preserved), scoped read-only API tokens, committed-only reads. Five decision forks surfaced. Grounds on the existing ehdb-service Flight scaffold + the #178 internal read contract. Registered in _Sidebar + Home. Tracks noetl/ai-meta#184.
