+# Delta Refinery
+
+Hub note for cross-project-relevant knowledge about Delta Refinery, a Ruby (Sequel + SQLite,
+Thor CLI) multi-level agent pipeline project. Local repo: `~/dev/delta-refinery`.
+
+Local codebase structure, ADRs, and stopgap-removal tracking live in the repo itself
+(`CLAUDE.md`, `docs/adr/`, `docs/delta-refinery-snapshot.md`) — this note indexes only vault
+knowledge that generalizes beyond this repo (tool behavior, conventions, patterns discovered
+while working on it).
