Rejection workflow: rejected tickets should go directly to "todo" not "in_progress"

## Code Review ### Test Results - Full test suite run: `bundle exec rspec` - Results: **687 examples, 5 failures, 7 pending** ### Failing Tests (Due to This PR) The PR changed the rejection workflow from `in_progress` to `todo`, but not all tests were updated: 1. **spec/features/approvals_spec.rb:42** - "User rejects a ticket" - Expected: `in_progress` (old behavior) - Got: `todo` (new behavior) - **Test needs update** 2. **spec/requests/complete_workflow_spec.rb:108** - "handles rejection workflow" - Line 138: `expect(ticket.status).to eq("in_progress")` - Line 156: Comment "Work continues (reject keeps it in in_progress)" - **Test needs update** 3. **spec/requests/multi_agent_coordination_spec.rb:20** - Worker and Reviewer coordination - Expected: `in_progress` after rejection - **Test needs update** 4. **spec/features/dashboard_spec.rb** - 2 pre-existing failures (unrelated to this PR) ### Tests Updated by PR - ✓ `spec/models/ticket_spec.rb` - Updated to expect `todo` - ✓ `spec/requests/api/v1/tickets_spec.rb` - Updated to expect `todo` ### Tests NOT Updated by PR (Causing Failures) - ✗ `spec/features/approvals_spec.rb` - Still expects `in_progress` - ✗ `spec/requests/complete_workflow_spec.rb` - Still expects `in_progress` - ✗ `spec/requests/multi_agent_coordination_spec.rb` - Still expects `in_progress` ### Code Quality Assessment **Workflow Change:** - The change from `in_progress` to `todo` for rejected tickets makes logical sense per the ticket requirements - Tickets rejected from review/approval should return to the ready queue (`todo`) rather than "actively being worked on" (`in_progress`) **Implementation:** - The model change in `app/models/ticket.rb` is correct - Comment updated to reflect new behavior: "Reject back to todo from any review/approval state" **Test Coverage Gap:** - The PR updated 2 test files but missed 3 other test files that depend on the rejection behavior - This resulted in 3 test failures that block the PR from passing ### Decision **FAIL - Incomplete Test Updates** The workflow change is correct, but the implementation is incomplete because not all affected tests were updated. The following tests need to be updated to expect `todo` instead of `in_progress` after rejection: 1. `spec/features/approvals_spec.rb:45` - Change `expect(ticket.status).to eq("in_progress")` to `expect(ticket.status).to eq("todo")` 2. `spec/requests/complete_workflow_spec.rb:138` - Change `expect(ticket.status).to eq("in_progress")` to `expect(ticket.status).to eq("todo")` 3. `spec/requests/complete_workflow_spec.rb:156` - Update comment and assertion 4. `spec/requests/multi_agent_coordination_spec.rb:104` - Change expectation to `todo` **Action Required:** Update these failing tests before the PR can be approved.
