+### Added
+
+- **Ephemeral molecules** (bd-2vh3) - Spawn molecules as ephemeral by default
+  - `bd mol spawn` creates ephemeral issues that live only in SQLite
+  - Ephemeral issues never export to JSONL (prevents zombie resurrection)
+  - Use `--persistent` flag to opt out of ephemeral spawning
+  - `bd mol squash` compresses ephemeral children into a digest issue
+  - `--summary` flag allows agents to provide AI-generated summaries
+
+### Fixed
+
+- **Comments not deleted with issue** (bd-687g) - `DeleteIssue` now cascades to comments table
