+# v0.3.4 Feature Expansion & Hardening - Implementation Summary
+
+8 improvements across error hardening, CRUD expansion, watch enhancements, and documentation.
+
+## Error Hardening (3 fixes)
+1. **export.rs** — Replaced `file.unwrap()` with `if let Some(ref path)` in CSV and Markdown export paths
+2. **main.rs** — Moved issue ID regex to `OnceLock` pattern (matching output.rs convention)
+3. **main.rs** — Improved `--filter` help text: documented dot-notation, `~=` operator, case-insensitivity, AND logic
+
+## CRUD Expansion (5 new subcommands)
+4. **roadmaps create** — `roadmapCreate` mutation with `--description`
+5. **roadmaps update** — `roadmapUpdate` mutation with `--name`, `--description`, `--dry-run`
+6. **initiatives create** — `initiativeCreate` mutation with `--description`, `--status`
+7. **initiatives update** — `initiativeUpdate` mutation with `--name`, `--description`, `--status`, `--dry-run`
+8. **documents delete** — `documentDelete` mutation with `--force`, `--dry-run`, confirmation prompt
+
+## Watch Expansion (2 new watch targets)
+9. **watch project** — Polls project `updatedAt` with state and progress display
+10. **watch team** — Polls team with active cycle info, resolves team key to UUID
