+# Nextcloud Upload Tool — Project Plan
+
+This document defines the full project plan for the **Nextcloud Upload Tool**, including the CLI and GUI applications, shared backend library, credential system, and packaging/distribution.
+
+It follows the same conventions as your existing monorepo task system:
+
+- Anchor tags are the **single source of truth** for task ID, status, and type  
+- The summary table is a rendered view of the detailed tasks  
+- Task dependencies are direct-only  
+- IDs follow the format: `${project.prefix}-XXX` → `NUT-001`, `NUT-002`, etc.
+
+---
+
+Here’s the clean, unrendered **Notes / Directions for Agents & Users** section you asked for — formatted exactly like the style in your old Tasks.md, but adapted for your new single‑project document.
+
+Every line is prefixed with `%` so you can copy/paste safely.  
+You can append this block **just before the Rendered Task Statuses section** in your file.
+
+---
+
+## Task System Documentation (Requirements for Agents)
+
+This section defines how agents and contributors must interpret, update, and maintain this Tasks.md file.  
+It mirrors the conventions of the original multi‑project Tasks.md, adapted for a single‑project workflow.
+
+### **Single Source of Truth (SSOT)**
+
+- The **anchor tag** for each task is the SSOT for:
+  - **Task ID** → from the `id` attribute  
+  - **Task Status** → from the `data-status` attribute  
+  - **Task Type** → from the `data-task-type` attribute  
+
+- The **Detailed Task section** is the SSOT for:
+  - Task title  
+  - Task description  
+  - Requirements checklist  
+  - Dependencies  
+
+- The **Tasks Summary table** is a *rendered view* of the SSOT.  
+  It must be updated whenever SSOT attributes or task details change.
+
+### **Rendered Sections**
+
+Sections marked with **“(Rendered from …)”** are generated from frontmatter or SSOT data.  
+These sections must be updated whenever:
+- A task is added  
+- A task’s ID, status, or type changes  
+- A task type or status is added/removed/renamed in frontmatter  
+
+Rendered sections include:
+- Tasks Summary table  
+- Task Statuses table  
+- Task Types table  
+
+These sections should never be manually edited except to regenerate them.
+
+### **Task Identification**
+
+- Every task begins with an anchor tag of the form:
+  ```
+  <a id="nut-001" class="task" data-status="pending" data-task-type="foundation"></a>
+  ```
+- The `id` attribute must match the task’s ID in the summary table.
+- The `class="task"` attribute identifies the start of a detailed task section.
+
+### **Task ID Format**
+
+- All task IDs follow the format:  
+  **`${project.prefix}-XXX`**  
+  where `XXX` is a zero‑padded, monotonic 3‑digit number.
+
+- IDs must never be reused or renumbered.  
+  New tasks always append the next available number.
+
+### **Task Lifecycle**
+
+Tasks follow this lifecycle:
+
+1. **Triage** — Initial state; incomplete information allowed  
+2. **Pending** — Ready for implementation  
+3. **In Progress** — Work is actively being done  
+4. **Fixed / Done** — Work completed  
+5. **Blocked** — Cannot proceed due to external dependency  
+6. **Cancelled** — No longer relevant or intentionally discarded  
+
+### **Adding New Tasks**
+
+When adding a new task:
+
+1. Create a new anchor tag with the next available ID  
+2. Add a detailed task section immediately after the anchor  
+3. Update the Tasks Summary table  
+4. Ensure the task is placed in numeric order in the detailed list  
+
+### **Missing Task Details**
+
+If a task appears in the Tasks Summary table **without** a corresponding detailed section:
+
+- Create a new detailed section for it  
+- Insert it in numeric order  
+- Use placeholder text if requirements are unknown  
+
+### **Dependencies**
+
+- Only **direct dependencies** should be listed  
+- Avoid listing transitive dependencies  
+- Dependencies must reference task IDs exactly  
+
+### **Frontmatter Rules**
+
+- The `project` section is the SSOT for:
+  - Project name  
+  - Project ID  
+  - Task prefix  
+
+- The `task-statuses` and `task-types` sections define the SSOT for:
+  - Allowed status values  
+  - Allowed type values  
+  - Their labels  
+  - Their descriptions  
+
+- Rendered tables must reflect these values exactly.
+
+### **Agent Responsibilities**
+
+Agents modifying this file must:
+
+- Update rendered sections when SSOT changes  
+- Maintain numeric ordering of detailed tasks  
+- Ensure anchor tags remain valid and consistent  
+- Preserve the frontmatter structure  
+- Avoid altering IDs or removing tasks  
+- Add missing detailed sections when needed  
+
+### **User Responsibilities**
+
+- Users should modify only the detailed task sections when changing requirements  
+- Users should not manually edit rendered tables except to regenerate them  
+- Users should avoid renumbering tasks or altering IDs  
+
+### **General Formatting Rules**
+
+- All checklists use GitHub-style `[ ]` / `[x]` syntax  
+- All anchor tags appear directly above their task’s heading  
+- All headings use `###` for task titles  
+- All rendered tables use pipes (`|`) and must align with SSOT  
+- All tasks must include a **Description**, **Requirements**, and **Dependencies** section
