Verified milestone sync handlers against SQLite schema: ## Schema Analysis Milestone fields in schema.py (lines 112-138): - id TEXT PRIMARY KEY (NOT NULL) - name TEXT NOT NULL - description TEXT (nullable) - status TEXT NOT NULL DEFAULT 'planned' - project_id TEXT (nullable, REFERENCES projects) - due TEXT (nullable) - created_at TEXT NOT NULL - updated_at TEXT NOT NULL - version INTEGER NOT NULL DEFAULT 1 - deleted_at TEXT (nullable) ## _insert_from_server Handler Verification (lines 1003-1022) All fields properly handled: - id: data["id"] - Required field, will raise KeyError if missing ✓ - name: data.get("name", "Untitled") - Default for NOT NULL ✓ - description: data.get("description") - Returns None for nullable ✓ **FIXED** - status: data.get("status", "planned") - Matches schema default ✓ - project_id: data.get("project_id") - Nullable, returns None ✓ - due: data.get("due") - Nullable, returns None ✓ - created_at: data.get("created_at", now_iso()) - Default for NOT NULL ✓ - updated_at: data.get("updated_at", now_iso()) - Default for NOT NULL ✓ - version: data.get("version", 1) - Matches schema default ✓ ## _update_from_server Handler Verification (lines 798-822) All fields properly handled: - name: COALESCE(?, name) - Preserves existing if None ✓ - description: COALESCE(?, description) - Preserves existing if None ✓ - status: COALESCE(?, status) - Preserves existing if None ✓ - project_id: direct assignment - Allows NULL ✓ - due: direct assignment - Allows NULL ✓ - updated_at: direct assignment - Always has value ✓ - version: COALESCE(?, version + 1) - Increments properly ✓ - deleted_at: set to NULL - Un-deletes entity ✓ ## Issue Found and Fixed **client/sync.py line 1014**: Changed description default from empty string "" to None - Old: data.get("description", "") - New: data.get("description") - Reason: description is nullable in schema, should default to None not empty string ## Test Results All sync tests pass: - test_create_milestone_syncs_to_server ✓ - test_update_milestone_syncs_to_server ✓ - test_delete_milestone_syncs_to_server ✓ - test_create_milestone_syncs_to_other_client ✓ - test_update_milestone_syncs_to_other_client ✓ Full test suite: 20 passed, 0 failed ## Summary Milestone sync handlers are now complete and correct. All fields match schema constraints, nullable fields default to None, and all tests pass.
