 - Spacing: Use two blank lines between detailed task blocks. Horizontal rules (`---`) are reserved for separating major top-level sections.
 
-### Maintenance Procedures
+### Table & Section Sorting Rules
 
-- **Adding a Task**: Append the next sequential ID, create the anchor tag and detailed section separated by two blank lines, and add the row to [Tasks Summary](#tasks-summary).
-- **Updating Status/Type**: Update the `data-status` and `data-task-type` attributes in the task anchor tag, the text fields in the task detail section, and the corresponding row in [Tasks Summary](#tasks-summary).
-- **Modifying Enums**: Any changes to available statuses or types must originate in the YAML frontmatter (`task-statuses` / `task-types`) and be re-rendered into the corresponding reference tables below.
+- **Tasks Summary Table**:
+  - Non-fixed/open tasks (`triage`, `pending`, `in_progress`, `blocked`) are positioned at the top.
+  - Fixed/done tasks are positioned at the bottom, sorted in **ascending numeric order** by task ID (`NUT-001`, `NUT-002`, `NUT-003`, ...).
+- **Detailed Tasks Section**:
+  - All detailed task sections remain in **strictly ascending numeric order** (`NUT-001`, `NUT-002`, `NUT-003`, ...).
+
+### Contributor & Agent Workflow
+
+1. **One Task at a Time**: Only one task is moved to `in_progress` and worked on per development turn.
+2. **Verification First**: All unit and workspace tests (`cargo test --workspace`) and frontend builds (`cd gui && npm run build`) must pass cleanly before marking a task Fixed.
+3. **Commit Handoff**: The agent updates [Tasks.md](#tasks-summary) upon task completion and pauses for the user to make the git commit. The agent does not execute commits or destructive git operations.
