+# 📘 How to Use the Sprint Playbook Template
+
+*(Guide for AI Agent)*
+
+---
+
+## 🎯 Purpose
+
+This guide explains how to generate a **Sprint Playbook** from the **Sprint Playbook Template**.
+The Playbook is the **authoritative plan and tracking file** for the Sprint.
+Your role as AI agent is to:
+
+1. Interpret the user’s Sprint goal.
+2. Analyze the current project state.
+3. Split work into clear user stories.
+4. Populate the Playbook with concise, actionable details.
+5. Ensure the Playbook defines a **minimal implementation** — no extra features beyond scope.
+
+---
+
+## 🛠 Step-by-Step Instructions
+
+### 1. Analyze User Input
+
+* Read the user’s description of what should be achieved in the Sprint.
+* Extract the **general goal** (e.g., “add authentication,” “improve reporting,” “fix performance issues”).
+* Note any explicit **constraints** (frameworks, coding styles, patterns).
+
+**If gaps, ambiguities, or contradictions are detected:**
+
+**MANDATORY PROCESS:**
+1. **STOP playbook creation immediately**
+2. **Ask user for specific clarification** with concrete questions:
+   * *"Do you want authentication for all users or just admins?"*
+   * *"Should performance improvements target backend response times or frontend rendering?"*
+   * *"You mentioned using Django, but the codebase uses Flask — should we migrate or stick with Flask?"*
+3. **Wait for user response** - do not proceed with assumptions
+4. **Repeat clarification cycle** until goal is completely unambiguous
+5. **Only then proceed** to create the playbook
+
+**CRITICAL RULE**: Never proceed with unclear requirements - this will cause blocking during implementation.
+
+---
+
+### 2. Assess Current State
+
+**MANDATORY STEPS:**
+1. Read project entry points (e.g., `main.py`, `index.js`, `app.py`)
+2. Identify and read core business logic modules
+3. Read configuration files (`.env`, `config.*`, etc.)
+4. Read dependency files (`package.json`, `requirements.txt`, `Cargo.toml`, etc.)
+5. List current main features available
+6. List known limitations or issues
+7. List relevant file paths
+8. Document runtime versions, frameworks, and libraries
+
+**Output Requirements:**
+* Keep descriptions factual and concise (2-3 sentences per item)
+* Focus only on functionality relevant to the sprint goal
+* Do not speculate about future capabilities
+
+---
+
+### 3. Sprint ID Selection (Mandatory Process)
+
+**EXACT STEPS TO FOLLOW:**
+1. **Check if `docs/sprints/` directory exists**
+   - If directory doesn't exist: set **Sprint ID = `01`**
+   - If directory exists: proceed to step 2
+
+2. **List existing sprint files**
+   - Search for files matching pattern: `docs/sprints/sprint-??-*.md`
+   - Extract only the two-digit numbers (ignore everything else)
+   - Example: `sprint-03-auth.md` → extract `03`
+
+3. **Calculate new ID**
+   - If no matching files found: set **Sprint ID = `01`**
+   - If files found: find maximum ID number and increment by 1
+   - Preserve zero-padding (e.g., `03` → `04`, `09` → `10`)
+
+**CRITICAL RULES:**
+- NEVER use IDs from example documents - examples are for formatting only
+- NEVER guess or assume sprint IDs
+- ALWAYS preserve two-digit zero-padding format
+- This is the single source of truth for Sprint ID assignment
+
+---
+
+### 4. Define Desired State
+
+**MANDATORY SECTIONS:**
+1. **New Features** - List exactly what new functionality will be added
+2. **Modified Features** - List existing features that will be changed
+3. **Expected Behavior Changes** - Describe how user/system behavior will differ
+4. **External Dependencies/Integrations** - List new libraries, APIs, or services needed
+
+**Requirements:**
+* Each item must be specific and measurable
+* Avoid vague terms like "improve" or "enhance" - be precise
+* Only include changes directly needed for the sprint goal
+
+---
+
+### 5. Break Down Into User Stories
+
+**STORY CREATION RULES:**
+1. Each story must be implementable independently
+2. Story should require 1-2 commits maximum
+3. Story must have measurable acceptance criteria
+4. Story must include specific DoD items
+
+**MANDATORY STORY COMPONENTS:**
+* **Story ID**: Sequential numbering (`US-1`, `US-2`, `US-3`...)
+* **Title**: 2-4 word description of the functionality
+* **Description**: Clear explanation of what needs to be implemented
+* **Acceptance Criteria**: Specific, testable conditions that must be met
+* **Definition of Done**: Concrete checklist (implemented, tested, docs updated, lint clean)
+* **Assignee**: Always `AI-Agent` for AI-implemented sprints
+* **Status**: Always starts as `🔲 todo`
+
+**STATUS PROGRESSION (AI must follow exactly):**
+* `🔲 todo` → `🚧 in progress` → `✅ done`
+* If blocked: any status → `🚫 blocked` (requires user intervention)
+* **CRITICAL**: If ANY story becomes `🚫 blocked`, STOP all sprint work immediately
+
+---
+
+### 6. Add Technical Instructions
+
+**REQUIRED SECTIONS:**
+* **Code Snippets/Patterns**: Include specific code examples that show structure
+* **Architecture Guidelines**: Define module boundaries, layering, design patterns
+* **Coding Style Conventions**: Specify naming rules, formatting, linting requirements
+* **Testing Strategy**: Define what testing is required (unit/integration, framework, coverage)
+
+**GUIDELINES:**
+* Provide concrete examples, not abstract descriptions
+* If multiple approaches exist, specify exactly which one to use
+* Include specific commands for building, testing, and linting
+* Reference existing project conventions where possible
+
+---
+
+### 7. Capture Risks and Dependencies
+
+* List potential **risks** (technical, integration, scope-related).
+* List **dependencies** (modules, libraries, APIs, data sources).
+
+---
+
+### 8. Apply Definition of Done (DoD)
+
+**USER STORY DoD (for each story):**
+* Must include specific, measurable items like:
+  * "Endpoint implemented and returns correct status codes"
+  * "Unit tests added with 80%+ coverage"
+  * "Documentation updated in README"
+  * "Code passes linter without errors"
+
+**SPRINT DoD STRUCTURE (mandatory separation):**
+
+**AI-Responsible Items** (AI MUST tick these when completed):
+* [ ] All user stories meet their individual Definition of Done
+* [ ] Code compiles and passes automated tests
+* [ ] Code is committed and pushed on branch `[feature/sprint-<id>]`
+* [ ] Documentation is updated
+* [ ] Sprint status updated to `✅ done`
+
+**User-Only Items** (AI MUST NEVER tick these):
+* [ ] Branch is merged into main
+* [ ] Production deployment completed (if applicable)
+* [ ] External system integrations verified (if applicable)
+
+**CRITICAL RULE**: AI agents must NEVER tick user-only DoD items under any circumstances.
+
+---
+
+---
+
+## ⚠️ Guardrail Against Overfitting
+
+If you are provided with **example Sprint Playbooks**:
+
+* Use them **only to understand formatting and structure**.
+* Do **not** copy their technologies, libraries, or domain-specific details unless explicitly relevant.
+* Always prioritize:
+
+  1. **Sprint Playbook Template**
+  2. **User instructions**
+  3. **Project state analysis**
+
+---
+
+## ✅ Output Requirements
+
+**MANDATORY CHECKLIST** - Sprint Playbook must have:
+
+1. ✅ **Correct Sprint ID** - Follow Sprint ID selection rule (increment from existing)
+2. ✅ **Complete metadata** - All fields in Sprint Metadata section filled
+3. ✅ **Current state analysis** - Based on actual project file examination
+4. ✅ **Specific desired state** - Measurable outcomes, not vague goals
+5. ✅ **Independent user stories** - Each story can be implemented separately
+6. ✅ **Testable acceptance criteria** - Each story has specific pass/fail conditions
+7. ✅ **Concrete DoD items** - Specific, actionable checklist items
+8. ✅ **Technical guidance** - Actual code snippets and specific instructions
+9. ✅ **Risk identification** - Potential blockers and dependencies listed
+10. ✅ **Proper DoD separation** - AI vs User responsibilities clearly marked
+
+**VALIDATION**: Before finalizing, verify that another AI agent could execute the sprint based solely on the playbook content without additional clarification.

+# 📘 Sprint Implementation Guidelines
+
+These guidelines define how the AI agent must implement a Sprint based on the approved **Sprint Playbook**.
+They ensure consistent execution, traceability, and alignment with user expectations.
+
+---
+
+## 0. Key Definitions
+
+**Logical Unit of Work (LUW)**: A single, cohesive code change that:
+- Implements one specific functionality 
+- Can be described in 1-2 sentences
+- Passes all relevant tests
+- Can be committed independently
+
+**Blocked Status (`🚫 blocked`)**: A user story cannot proceed due to:
+- Missing external dependencies 
+- Conflicting requirements
+- Failed tests that cannot be auto-fixed
+- Missing user clarification
+
+**AI-Responsible DoD Items**: Checkboxes the AI can verify and tick:
+- Code compiles and passes tests
+- Code committed and pushed to branch
+- Documentation updated
+- Sprint status updated to done
+
+**User-Only DoD Items**: Checkboxes only the user can tick:
+- Branch merged into main
+- Production deployment completed
+- External integrations verified
+
+---
+
+## 1. Git & Version Control Rules
+
+### 1.1 Commit Granularity
+
+* Commit after each **logical unit of work (LUW)**.
+* A user story may span multiple commits.
+* Do not mix unrelated changes (e.g., no “feature + formatting” in one commit).
+* Include tests for the LUW in the same commit if the story's DoD requires tests.
+* Local WIP commits may be squashed before delivery, but history must remain clear.
+
+### 1.2 Commit Message Style
+
+* Use **Conventional Commits** format:
+
+  ```
+  <type>(<scope>): <subject>
+
+  <body>
+
+  Refs: <Story-ID(s)>
+  ```
+* Example:
+
+  ```
+  feat(auth): add JWT middleware
+
+  Introduces HS256 verification for protected routes.
+  Returns 401 for missing/invalid/expired tokens.
+
+  Refs: US-3
+  ```
+* Allowed `<type>`: `feat`, `fix`, `refactor`, `perf`, `test`, `docs`, `build`, `ci`, `style`, `chore`, `revert`.
+
+### 1.3 Branching Strategy
+
+* Use **one dedicated branch per Sprint**:
+
+  * Naming: `feature/sprint-<id>-<short-goal>`
+  * Example: `feature/sprint-07-auth`
+* Branch created from `main` and kept up to date via rebase or merge.
+* `main` remains protected.
+
+**Sprint ID source of truth:** The Sprint ID **must** follow the “Sprint ID selection rule” in the How-to guide.  
+If no prior Playbooks exist in `docs/sprints/`, start at `01`; otherwise increment the greatest existing two-digit ID (keep zero-padding).
+
+### 1.4 Commit & Push Policy
+
+* Run build and fix issues before committing.
+* Commit and push regularly (at least daily).
+
+### 1.5 PR / Merge Rules
+
+* The AI agent **must not merge or open PRs**.
+* The AI’s responsibility ends with:
+  * Implementing all user stories.
+  * Committing changes to the Sprint branch.
+  * Ensuring the branch passes all tests.
+* The **user merges** the Sprint branch into `main`.
+
+---
+
+## 2. Playbook Status Updating
+
+### 2.1 User Stories
+* Update each story’s `Status` field (`🔲 todo` → `🚧 in progress` → `✅ done`).
+* Mark `✅ done` only when the story’s **DoD** is fully satisfied.
+
+### 2.2 Sprint Status (Top-Level)
+
+* Keep the top-level Sprint status current:
+
+  ```
+  Status: [🔲 not started | 🚧 in progress | 🛠️ implementing <user story id> | ✅ done]
+  ```
+
+### 2.3 Commit & Status Sync
+
+**Strict choreography**
+
+- **First commit of a story**  
+  Include the first code changes for `US-#` **and** update the Playbook in the same commit:
+  - Sprint status → `🛠️ implementing US-#`
+  - Story `US-#` status → `🚧 in progress`
+
+- **Final commit of a story**  
+  Include the completing code changes for `US-#` **and** update the Playbook in the same commit:
+  - Story `US-#` status → `✅ done`
+  - Tick any **AI-responsible** DoD items that became true in this commit (see below)
+
+- **DoD checkbox updates**  
+  Tick AI-responsible DoD items **in the same commit** that makes them true:
+  - ✅ Code compiles and passes automated tests
+  - ✅ Code is committed and pushed on branch  
+  - ✅ Documentation is updated
+  - ✅ Sprint status updated to done
+  
+  **NEVER tick user-only DoD items** such as:
+  - ❌ Branch is merged into main
+  - ❌ Production deployment completed
+  - ❌ External systems integration verified
+  
+- **No status-only commits**  
+  Avoid standalone “status update” commits. If a previous commit forgot a status/DoD tick, include it in the **very next** code commit for that story.
+
+
+### 2.4 Location & Traceability
+
+* Store Playbook in repo under `docs/sprints/sprint-<id>.md`.
+* Reference Story IDs in commit messages.
+
+### 2.5 End-of-Sprint Update
+
+* Update Sprint status → `✅ done`.
+* Update Playbook with final status changes.
+* Stop execution.
+
+---
+
+## 3. Coding & Testing Standards
+
+### 3.1 Style Guides
+
+* Follow project’s existing style guides.
+* Follow existing style guides exactly unless deviation prevents story completion.
+* If deviation is necessary, document rationale in commit body and ask user for approval.
+* Do not mix stylistic mass-changes with functional code.
+
+### 3.2 Code Quality
+
+* Keep changes minimal and scoped.
+* Favor readability and idiomatic solutions.
+* Maintain module boundaries.
+* Add/update docstrings and project docs when behavior changes.
+
+### 3.3 Testing Policy
+
+* **Unit tests**: required for all backend logic, utilities, data processing, and business logic.
+* **UI tests**: required only if the story's DoD explicitly mentions testing UI behavior.
+* Pure styling changes (CSS-only) do not require tests.
+* **Integration/E2E tests**: explicitly out of scope.
+* Maintain existing test coverage levels.
+
+### 3.4 Test Execution
+
+* Run relevant tests locally before committing.
+
+### 3.5 Prohibited
+
+* No large-scale refactors unless explicitly requested.
+* No new frameworks or test harnesses.
+* No speculative features.
+
+---
+
+## 4. Execution Flow
+
+### 4.1 Story Execution Workflow
+
+**STEP 1: Start Story**
+1. Verify previous story is `✅ done` (if `🚫 blocked`, STOP - do not proceed)
+2. Change story status from `🔲 todo` to `🚧 in progress`
+3. Change sprint status to `🛠️ implementing US-#`
+4. Commit these playbook changes with first code changes for the story
+
+**STEP 2: Implement Story (Loop)**
+For each LUW in the story:
+1. Write code for one logical unit of work
+2. Write tests if required by story DoD
+3. Run tests and fix any failures
+4. Commit LUW with conventional commit message including "Refs: US-#"
+5. Push commit to branch
+
+**STEP 3: Complete Story**
+1. Verify all story acceptance criteria are met
+2. Verify all AI-responsible DoD items are complete
+3. Run final test suite 
+4. Update story status to `✅ done`
+5. Tick completed AI-responsible DoD checkboxes 
+6. Commit these playbook updates
+7. Push final commit
+
+**STEP 4: Next Story or Block Handling**
+- If current story is `✅ done`: proceed to STEP 1 for next story
+- If current story is `🚫 blocked`: STOP execution, notify user, wait for instructions
+- If no more stories and all are `✅ done`: proceed to End-of-Sprint workflow
+
+### 4.2 Blocking Workflow
+
+**When ANY story becomes `🚫 blocked`:**
+1. Mark story status as `🚫 blocked` with specific reason
+2. Commit playbook changes immediately
+3. Notify user with blocker details
+4. **STOP all sprint work** - do not proceed to next stories
+5. Wait for user to provide resolution instructions
+6. Only resume when user gives explicit unblocking guidance
+
+**Critical Rule: NO STORY PROGRESSION DURING BLOCKING**
+- Do not start new stories while any story is `🚫 blocked`
+- Do not attempt workarounds or fixes without user approval
+- Sprint execution is completely paused until all blocks are resolved
+
+### 4.3 End-of-Sprint Workflow
+
+**STEP 1: Final Verification**
+1. Verify all stories are `✅ done` (if any are `🚫 blocked`, STOP and notify user)
+2. Run complete test suite
+3. Update any remaining documentation
+
+**STEP 2: Sprint Completion**  
+1. Update sprint status to `✅ done`
+2. Tick any remaining AI-responsible DoD items
+3. Commit final changes
+4. Push branch to remote
+
+**STEP 3: Stop Execution**
+- Report sprint completion to user
+- Do not merge branch or open PRs
+
+---
+
+## 5. Documentation & Communication
+
+### 5.1 Inline Comments
+
+* Update/add comments for new or changed functions/classes/modules.
+* Keep concise and technical.
+
+### 5.2 Project Docs
+
+* Update README/API docs/configs when public-facing behavior changes.
+* Docs updated in **same commit** as related code.
+
+### 5.3 Exclusions
+
+* No separate Sprint summary reports.
+* No speculative documentation outside scope.
+
+---
+
+## 6. Failure & Error Handling
+
+### 6.1 Error Response Protocol
+
+**MANDATORY STEPS when encountering any blocker:**
+1. Stop current work immediately
+2. Mark story status as `🚫 blocked` in playbook
+3. Add specific blocker reason to playbook
+4. Commit playbook changes
+5. Ask user for explicit resolution 
+6. Wait for user response - do not proceed
+
+### 6.2 Specific Error Actions
+
+**Test Failures:**
+1. Run tests again to confirm failure
+2. Copy exact error messages
+3. Mark story as `🚫 blocked` with reason: "Tests failing: [error summary]"
+4. Ask user: "Tests are failing with error: [exact error]. Should I fix this or wait for guidance?"
+
+**Missing Dependencies:**
+1. Identify exactly what is missing
+2. Mark story as `🚫 blocked` with reason: "Missing dependency: [name]"
+3. Ask user: "Missing dependency [name]. Should I install it or mock it for testing?"
+
+**Conflicting Requirements:**
+1. Document the specific conflict
+2. Mark story as `🚫 blocked` with reason: "Conflicting requirements: [details]"  
+3. Ask user: "Found conflicting requirements: [details]. Which approach should I follow?"
+
+**Build/Compilation Failures:**
+1. Copy exact build error
+2. Mark story as `🚫 blocked` with reason: "Build failing: [error summary]"
+3. Ask user: "Build is failing with: [exact error]. How should I resolve this?"
+
+### 6.3 Prohibited Actions During Blocking
+
+**NEVER do these when `🚫 blocked`:**
+- Continue to next story
+- Make speculative fixes
+- Change requirements to work around issues
+- Skip failing tests
+- Implement workarounds without approval
+
+### 6.4 Unblocking Requirements
+
+**AI can only resume work after user provides:**
+- Explicit instruction on how to resolve the blocker
+- Modified requirements if applicable  
+- Confirmation that workaround approach is acceptable
+
+---
+
+## 7. Sprint Wrap-Up
+
+### 7.1 Completion Criteria
+
+Sprint is complete when:
+
+* All user stories = `✅ done`.
+* Sprint status = `✅ done`.
+* Final status updates completed.
+* Code committed to Sprint branch.
+* Docs and comments updated.
+* Tests passing (when applicable).
+
+### 7.2 Handover
+
+* AI stops execution.
+* Sprint branch remains unmerged.
+
+### 7.3 Final Note
+
+* No changes beyond Sprint scope.
+* Playbook + Git history act as audit record.

+# Sprint 01: adding barcode print support
+
+In this sprint we will add a capability to print a table containing all 2D barcode images for a given month.
+
+## Changes to the UI
+
+In the UI within month card a button will be added:
+
+* location: at the bottom - next to "Add a new realestate"
+* tooltip:
+  - EN tooltip: "Print 2D codes"
+  - HR tooltip: "Ispis 2d kodova"
+* icon: printer
+* action on pressed: show a print preview in the new tab/window
+
+## Print preview
+
+Print preview will contain a table of all 2D barcodes found within that month.
+
+In print preview the table will have 3 columns:
+1. row index
+2. bill info:
+  - `yyyy-mm` formated current month's date
+  - realestate name
+  - bill name
+3. 2D barcode image
+
+In top-left corner of the page (position fixed) will be a printer icon which will trigger the print action.
+The icon will not be visible in the printed version of the document.
+
+## Styling
+* use Tailwind CSS
+* print dialog: native dialog
+* print type: B&W
+* paper size: A4
+* when printerd the 2D barcode will have the following size:
+  - width = 58 mm
+  - height: automatic without changing proportions of original image

+# 📑 Sprint Playbook: Barcode Print Support
+
+## 0. Sprint Status
+
+```
+Status: 🔲 not started
+```
+
+---
+
+## 1. Sprint Metadata
+
+* **Sprint ID:** 01
+* **Start Date:** 2025-01-14
+* **End Date:** 2025-01-16
+* **Sprint Goal:** Add capability to print a table containing all 2D barcode images for a given month
+* **Team/Agent Responsible:** AI-Agent (Claude Sonnet 4)
+* **Branch Name (Git):** feature/sprint-01
+
+---
+
+## 2. Current State of Software
+
+*(Snapshot of the project before Sprint work begins)*
+
+* **Main Features Available:** 
+  - Multi-user utility bills tracking system
+  - Monthly billing periods with expandable MonthCard UI components
+  - Location and bill management with CRUD operations
+  - 2D barcode scanning and storage (bills already have `barcodeImage` field)
+  - PDF processing capabilities with `@zxing/library` and `pdfjs-dist`
+  - Internationalization support (Croatian/English)
+
+* **Known Limitations / Issues:** 
+  - No print functionality for barcode overview
+  - Barcode images stored as base64 strings but not displayed in bulk format
+  - No print-optimized styling or layout
+
+* **Relevant Files / Modules:** 
+  - `app/ui/MonthCard.tsx` - Monthly accordion components
+  - `app/ui/MonthLocationList.tsx` - Main month listing container
+  - `app/lib/db-types.ts` - Bill interface with `barcodeImage` field
+  - `app/lib/actions/locationActions.ts` - Data fetching for locations/bills
+  - Package dependencies: `@zxing/library`, `@zxing/browser`, `pdfjs-dist`
+
+* **Environment / Dependencies:** 
+  - Node.js >=18.17.0
+  - Next.js 14 with App Router and TypeScript
+  - Tailwind CSS 3.4.0 with DaisyUI 4.5.0
+  - MongoDB 6.3.0 for data persistence
+
+---
+
+## 3. Desired State of Software
+
+*(Target state after Sprint is complete)*
+
+* **New Features:** 
+  - Print 2D codes button in each MonthCard
+  - Print preview page with barcode table layout
+  - Print-optimized styling with 58mm barcode width specification
+  - Fixed print icon for triggering native print dialog
+
+* **Modified Features:** 
+  - MonthCard component enhanced with print button
+  - New print route and page component added to Next.js routing
+
+* **Expected Behavior Changes:** 
+  - Users can access print functionality from month view
+  - Print preview opens in new tab/window
+  - Barcode table displays with row index, bill info, and barcode image
+  - Print layout optimized for A4 paper in B&W
+
+* **External Dependencies / Integrations:** 
+  - Native browser print dialog integration
+  - CSS print media queries for optimized print output
+
+---
+
+## 4. User Stories
+
+| Story ID | Title | Description | Acceptance Criteria | Definition of Done | Assignee | Status |
+| -------- | ----- | ----------- | ------------------- | ------------------ | -------- | ------ |
+| US-1 | Add Print Button | Add print 2D codes button to MonthCard component | Button appears next to "Add a new realestate", has printer icon, tooltips in EN/HR, opens print preview on click | Button implemented, styled with DaisyUI, tooltips working, click handler implemented, **user testing completed** | AI-Agent | ✅ done |

+| US-4 | Print Optimization | Apply print-specific CSS styling | 58mm barcode width, A4 paper size, B&W print, fixed print icon (hidden in print) | CSS print media queries added, barcode sizing correct, print icon positioned and hidden from print, **user testing completed** | AI-Agent | 🔲 todo |
+
+**Status options:** `🔲 todo`, `🚧 in progress`, `🚫 blocked`, `✅ done`
+
+---
+
+## 5. Technical Instructions
+
+*(Guidance to help AI converge quickly on the correct solution)*
+
+* **Code Snippets / Patterns:**
+
+  ```typescript
+  // Print button component pattern (integrate into MonthCard.tsx)
+  import { PrinterIcon } from '@heroicons/react/24/outline';
+  
+  const handlePrintClick = () => {
+    window.open(`/print/${yearMonth.year}/${yearMonth.month}`, '_blank');
+  };
+  
+  <button 
+    className="btn btn-ghost btn-sm" 
+    onClick={handlePrintClick}
+    title={t("print-codes-tooltip")}
+  >
+    <PrinterIcon className="h-4 w-4" />
+    {t("print-codes-label")}
+  </button>
+  ```
+
+  ```typescript
+  // Print page route structure: app/[locale]/print/[year]/[month]/page.tsx
+  interface PrintPageProps {
+    params: { year: string; month: string; locale: string };
+  }
+  
+  export default async function PrintPage({ params }: PrintPageProps) {
+    const locations = await fetchAllLocations(parseInt(params.year));
+    // Filter for specific month and extract bills with barcodes
+  }
+  ```
+
+  ```css
+  /* Print-specific CSS */
+  @media print {
+    .no-print { display: none !important; }
+    .barcode-cell img { width: 58mm; height: auto; }
+    @page { size: A4; margin: 1in; }
+  }
+  ```
+
+* **Architecture Guidelines:** 
+  - Follow existing Next.js App Router patterns with `[locale]` prefix
+  - Use server components for data fetching, client components only when needed
+  - Apply existing `withUser` HOF pattern for authenticated data access
+  - Maintain separation between UI components (`app/ui/`) and business logic
+
+* **Coding Style Conventions:** 
+  - Use TypeScript with existing interface patterns from `db-types.ts`
+  - Follow DaisyUI component classes and Tailwind utilities
+  - Use existing translation pattern with `useTranslations()` hook
+  - Maintain existing file naming conventions (PascalCase for components)
+
+* **Testing Strategy:** 
+  - AI agent implements feature and stops at testing checkpoint
+  - AI provides specific test instructions with expected behavior to user
+  - User performs manual testing and reports results (pass/fail with details)
+  - AI iterates on failures until user confirms all tests pass
+  - Process repeats for each user story until sprint completion
+
+---
+
+## 6. Risks and Dependencies
+
+* **Risks:** 
+  - Browser print dialog compatibility across different browsers
+  - Barcode image quality in print output
+  - CSS print media query support variations
+  - Large number of barcodes may cause performance issues in print preview
+
+* **Dependencies:** 
+  - Existing barcode data in `Bill.barcodeImage` field
+  - `@heroicons/react` for printer icon
+  - Tailwind CSS print utilities
+  - Next.js routing and internationalization setup
+
+---
+
+## 7. Sprint Definition of Done (DoD)
+
+The Sprint is complete when:
+
+**AI-Responsible Items** (AI agent can verify and tick):
+* [ ] Print button added to MonthCard with proper styling and tooltips
+* [ ] Print route `/[locale]/print/[year]/[month]` implemented and functional  
+* [ ] Print preview page displays barcode table with correct layout
+* [ ] CSS print media queries applied with 58mm barcode width specification
+* [ ] Print icon positioned fixed and hidden from print output
+* [ ] All user stories meet their individual Definition of Done
+* [ ] Code compiles and passes automated tests (`npm run build`)
+* [ ] Code formatting validated (`npm run prettier:check`)
+* [ ] Code is committed and pushed on branch `feature/sprint-01`
+* [ ] Sprint status updated to `✅ done`
+
+**User-Only Items** (Only user can verify and tick):
+* [ ] Branch is merged into main
+* [ ] Print functionality tested across target browsers
+* [ ] Print output quality validated on physical printer

Subject: [PATCH 06/12] feat: implement US-4 - complete print optimization with
 CSS media queries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add comprehensive CSS print media queries for A4 paper optimization
- Implement 69.6mm barcode width specification (20% larger than original 58mm)
- Apply B&W print color optimization forcing all elements to black/white
- Add page break handling to prevent table rows from splitting across pages
- Fix table cropping issue by removing excessive width and reducing container padding
- Optimize print layout with zero padding for maximum table space utilization
- Ensure header/button elements hidden from print output with proper CSS

+# 📘 How to Use the Sprint Playbook Template (Improved)
+
+*(Enhanced Guide for AI Agent)*
+
+---
+
+## 🎯 Purpose
+
+This enhanced guide explains how to generate a **Sprint Playbook** from the **Improved Sprint Playbook Template**.
+The Playbook serves as the **single source of truth** for sprint planning, execution, and tracking.
+
+**AI Agent Role:**
+1. Analyze user requirements with enhanced clarity checking
+2. Perform comprehensive project state assessment
+3. Create granular, testable user stories with dependencies
+4. Populate playbook with actionable technical guidance
+5. Establish quality gates and risk mitigation strategies
+6. Enable iterative refinement based on user feedback
+
+---
+
+## 🛠 Enhanced Step-by-Step Instructions
+
+### 1. Analyze User Input (Enhanced)
+
+**MANDATORY ANALYSIS PROCESS:**
+1. **Extract Primary Goal**: What is the main business/technical objective?
+2. **Identify Scope Boundaries**: What is explicitly included/excluded?
+3. **Parse Technical Constraints**: Frameworks, patterns, performance requirements
+4. **Assess Complexity Level**: Simple (1-2 days), Medium (3-5 days), Complex (1+ weeks)
+5. **Identify Integration Points**: Other systems, APIs, data sources
+6. **Check for Non-Functional Requirements**: Security, performance, accessibility
+
+**Enhanced Clarity Checking:**
+If ANY of these conditions are met, STOP and ask for clarification:
+
+- **Vague Success Criteria**: "improve", "enhance", "make better" without metrics
+- **Missing Technical Details**: Which specific framework version, API endpoints, data formats
+- **Unclear User Experience**: No mention of who uses the feature or how
+- **Ambiguous Scope**: Could be interpreted as either small change or major feature
+- **Conflicting Requirements**: Performance vs. feature richness, security vs. usability
+- **Missing Dependencies**: References to undefined components, services, or data
+
+**Structured Clarification Process:**
+1. **Categorize Unknowns**: Technical, Business, User Experience, Integration
+2. **Ask Specific Questions**: Provide 2-3 concrete options when possible
+3. **Request Examples**: "Can you show me a similar feature you like?"
+4. **Validate Understanding**: Repeat back interpretation for confirmation
+
+---
+
+### 2. Assess Current State (Comprehensive)
+
+**MANDATORY DISCOVERY STEPS:**
+1. **Read Core Application Files**:
+   - Entry points: `main.py`, `index.js`, `app.py`, `src/main.ts`
+   - Configuration: `.env`, `config.*`, `settings.py`, `next.config.js`
+   - Package management: `package.json`, `requirements.txt`, `Cargo.toml`, `pom.xml`
+
+2. **Analyze Architecture**:
+   - Directory structure and organization patterns
+   - Module boundaries and dependency flows
+   - Data models and database schemas
+   - API endpoints and routing patterns
+
+3. **Review Testing Infrastructure**:
+   - Test frameworks and utilities available
+   - Current test coverage and patterns
+   - CI/CD pipeline configuration
+   - Quality gates and automation
+
+4. **Assess Documentation**:
+   - README completeness and accuracy
+   - API documentation status
+   - Code comments and inline docs
+   - User guides or tutorials
+
+5. **Identify Technical Debt**:
+   - Known issues or TODOs
+   - Deprecated dependencies
+   - Performance bottlenecks
+   - Security vulnerabilities
+
+**Output Requirements:**
+- **Factual Assessment**: No speculation, only observable facts
+- **Relevance Filtering**: Focus on sprint-related components only
+- **Version Specificity**: Include exact version numbers for all dependencies
+- **Gap Identification**: Clearly note missing pieces needed for sprint success
+
+---
+
+### 3. Sprint ID Selection (Enhanced)
+
+**EXACT ALGORITHM:**
+1. **Check Directory Structure**:
+   ```bash
+   if docs/sprints/ exists:
+     scan for files matching "sprint-\d\d-*.md"
+   else:
+     create directory and use "01"
+   ```
+
+2. **Extract and Validate IDs**:
+   - Use regex: `sprint-(\d\d)-.*\.md`
+   - Validate two-digit format with zero padding
+   - Sort numerically (not lexicographically)
+
+3. **Calculate Next ID**:
+   - Find maximum existing ID
+   - Increment by 1
+   - Ensure zero-padding (sprintf "%02d" format)
+
+4. **Conflict Resolution**:
+   - If gaps exist (e.g., 01, 03, 05), use next in sequence (04)
+   - If no pattern found, default to "01"
+   - Never reuse IDs even if sprint was cancelled
+
+**Validation Checkpoint**: Double-check calculated ID against filesystem before proceeding.
+
+---
+
+### 4. Define Desired State (Enhanced)
+
+**MANDATORY SECTIONS WITH EXAMPLES:**
+
+1. **New Features** (Specific):
+   ```
+   ❌ Bad: "User authentication system"
+   ✅ Good: "JWT-based login with Google OAuth integration, session management, and role-based access control"
+   ```
+
+2. **Modified Features** (Before/After):
+   ```
+   ❌ Bad: "Improve dashboard performance"
+   ✅ Good: "Dashboard load time: 3.2s → <1.5s by implementing virtual scrolling and data pagination"
+   ```
+
+3. **Expected Behavior Changes** (User-Visible):
+   ```
+   ❌ Bad: "Better error handling"
+   ✅ Good: "Invalid form inputs show inline validation messages instead of generic alerts"
+   ```
+
+4. **External Dependencies** (Version-Specific):
+   ```
+   ❌ Bad: "Add React components"
+   ✅ Good: "Add @headlessui/react ^1.7.0 for accessible dropdown components"
+   ```
+
+**Quality Checklist**:
+- Each item is independently verifiable
+- Success criteria are measurable
+- Implementation approach is technically feasible
+- Dependencies are explicitly listed with versions
+
+---
+
+### 5. Break Down Into User Stories (Enhanced)
+
+**STORY GRANULARITY RULES:**
+- **Maximum Implementation Time**: 4-6 hours of focused work
+- **Independent Testability**: Each story can be tested in isolation
+- **Single Responsibility**: One clear functional outcome per story
+- **Atomic Commits**: Typically 1-2 commits per story maximum
+
+**ENHANCED STORY COMPONENTS:**
+
+1. **Story ID**: Sequential numbering with dependency tracking
+2. **Title**: Action-oriented, 2-4 words (e.g., "Add Login Button", "Implement JWT Validation")
+3. **Description**: Includes context, acceptance criteria preview, technical approach
+4. **Acceptance Criteria**: 3-5 specific, testable conditions using Given/When/Then format
+5. **Definition of Done**: Includes "user testing completed" for all user-facing changes
+6. **Dependencies**: References to other stories that must complete first
+7. **Estimated Time**: Realistic hour estimate for planning
+8. **Risk Level**: Low/Medium/High based on technical complexity
+
+**ACCEPTANCE CRITERIA FORMAT:**
+```
+Given [initial state]
+When [user action or system trigger]
+Then [expected outcome]
+And [additional verifications]
+```
+
+**Example User Story:**
+```
+| US-3 | Implement JWT Validation | Create middleware to validate JWT tokens on protected routes | Given a request to protected endpoint, When JWT is missing/invalid/expired, Then return 401 with specific error message, And log security event | Middleware implemented, unit tests added, error handling tested, security logging verified, **user testing completed** | AI-Agent | 🔲 todo | 3 hours | US-1, US-2 |
+```
+
+**DEPENDENCY MANAGEMENT:**
+- Use topological sorting for story order
+- Identify critical path and potential parallelization
+- Plan for dependency failures or delays
+- Consider story splitting to reduce dependencies
+
+---
+
+### 6. Add Technical Instructions (Comprehensive)
+
+**REQUIRED SECTIONS WITH DEPTH:**
+
+1. **Code Snippets/Patterns** (Executable Examples):
+   ```typescript
+   // Actual working example following project conventions
+   export const authenticatedRoute = withAuth(async (req: AuthRequest, res: Response) => {
+     const { userId } = req.user; // from JWT middleware
+     const data = await fetchUserData(userId);
+     return res.json({ success: true, data });
+   });
+   ```
+
+2. **Architecture Guidelines** (Specific Patterns):
+   - **Layer Separation**: "Controllers in `/api/`, business logic in `/services/`, data access in `/repositories/`"
+   - **Error Handling**: "Use Result<T, E> pattern, never throw in async functions"
+   - **State Management**: "Use Zustand for client state, React Query for server state"
+
+3. **Coding Style Conventions** (Tool-Specific):
+   - **Naming**: "Components: PascalCase, functions: camelCase, constants: SCREAMING_SNAKE_CASE"
+   - **Files**: "Components end with `.tsx`, utilities with `.ts`, tests with `.test.ts`"
+   - **Imports**: "Absolute imports with `@/` alias, group by type (libraries, internal, relative)"
+
+4. **Testing Strategy** (Framework-Specific):
+   - **Unit Tests**: "Jest + Testing Library, minimum 80% coverage for business logic"
+   - **Integration**: "Supertest for API endpoints, test database with cleanup"
+   - **Manual Testing**: "User validates UI/UX after each user-facing story completion"
+
+5. **Quality Gates** (Automated Checks):
+   - **Build**: "`npm run build` must pass without errors"
+   - **Lint**: "`npm run lint:check` must pass with zero warnings"
+   - **Format**: "`npm run prettier:check` must pass"
+   - **Tests**: "`npm test` must pass with coverage thresholds met"
+
+---
+
+### 7. Capture Risks and Dependencies (Proactive)
+
+**ENHANCED RISK ASSESSMENT:**
+
+1. **Technical Risks** (with Mitigation):
+   ```
+   Risk: "JWT library might not support RS256 algorithm"
+   Impact: High (blocks authentication)
+   Probability: Low
+   Mitigation: "Research jsonwebtoken vs. jose libraries in discovery phase"
+   ```
+
+2. **Integration Risks** (with Fallbacks):
+   ```
+   Risk: "Google OAuth API rate limits during development"
+   Impact: Medium (slows testing)
+   Probability: Medium
+   Fallback: "Mock OAuth responses for local development"
+   ```
+
+3. **Timeline Risks** (with Buffers):
+   ```
+   Risk: "Database migration complexity unknown"
+   Impact: High (affects multiple stories)
+   Buffer: "Add 20% time buffer, prepare manual migration scripts"
+   ```
+
+**DEPENDENCY TRACKING:**
+- **Internal Dependencies**: Other modules, shared utilities, database changes
+- **External Dependencies**: Third-party APIs, service availability, credentials
+- **Human Dependencies**: Design assets, content, domain expertise
+- **Infrastructure Dependencies**: Deployment access, environment variables, certificates
+
+---
+
+### 8. Enhanced Quality Gates
+
+**CODE QUALITY GATES:**
+- [ ] **Static Analysis**: ESLint, SonarQube, or equivalent passes
+- [ ] **Security Scan**: No high/critical vulnerabilities in dependencies
+- [ ] **Performance**: No significant regression in key metrics
+- [ ] **Accessibility**: WCAG compliance for user-facing changes
+
+**TESTING QUALITY GATES:**

+# 📘 Sprint Implementation Guidelines (Improved)
+
+These enhanced guidelines define how the AI agent must implement a Sprint based on the approved **Sprint Playbook**.
+They ensure consistent execution, comprehensive testing, proactive risk management, and optimal user collaboration.
+
+---
+
+## 0. Key Definitions (Enhanced)
+
+**Logical Unit of Work (LUW)**: A single, cohesive code change that:
+- Implements one specific functionality or fixes one specific issue
+- Can be described in 1-2 sentences with clear before/after behavior
+- Passes all relevant tests and quality gates
+- Can be committed independently without breaking the system
+- Takes 30-90 minutes of focused implementation time
+
+**Testing Checkpoint**: A mandatory pause where AI provides specific test instructions to user:
+- Clear step-by-step test procedures
+- Expected behavior descriptions
+- Pass/fail criteria
+- What to look for (visual, functional, performance)
+- How to report issues or failures
+
+**Blocked Status (`🚫 blocked`)**: A user story cannot proceed due to:
+- Missing external dependencies that cannot be mocked/simulated
+- Conflicting requirements discovered during implementation
+- Failed tests that require domain knowledge to resolve
+- Technical limitations requiring architecture decisions
+- User input needed for UX/business logic decisions
+
+**Iterative Refinement**: Process of making improvements based on user testing:
+- User reports specific issues or improvement requests
+- AI analyzes feedback and proposes solutions
+- Implementation of fixes follows same LUW/commit pattern
+- Re-testing until user confirms satisfaction
+
+---
+
+## 1. Enhanced Git & Version Control Rules
+
+### 1.1 Commit Granularity (Refined)
+
+**MANDATORY COMMIT PATTERNS:**
+* **Feature Implementation**: One LUW per commit
+* **Test Addition**: Included in same commit as feature (not separate)
+* **Documentation Updates**: Included in same commit as related code changes
+* **Bug Fixes**: One fix per commit with clear reproduction steps in message
+* **Refactoring**: Separate commits, no functional changes mixed in
+
+**COMMIT QUALITY CRITERIA:**
+* Build passes after each commit
+* Tests pass after each commit
+* No temporary/debug code included
+* All related files updated (tests, docs, types)
+
+### 1.2 Commit Message Style (Enhanced)
+
+**STRICT FORMAT:**
+```
+<type>(scope): <subject>
+
+<body>
+
+<footer>
+```
+
+**ENHANCED TYPES:**
+* `feat`: New feature implementation
+* `fix`: Bug fix or issue resolution
+* `refactor`: Code restructuring without behavior change
+* `perf`: Performance improvement
+* `test`: Test addition or modification
+* `docs`: Documentation updates
+* `style`: Code formatting (no logic changes)
+* `chore`: Maintenance tasks (dependency updates, build changes)
+* `i18n`: Internationalization changes
+* `a11y`: Accessibility improvements
+
+**IMPROVED EXAMPLES:**
+```
+feat(auth): implement JWT token validation middleware
+
+Add Express middleware for JWT token verification:
+- Validates token signature using HS256 algorithm
+- Extracts user ID and role from payload
+- Returns 401 for missing/invalid/expired tokens
+- Adds user context to request object for downstream handlers
+
+Refs: US-3
+Tests: Added unit tests for middleware edge cases
+```
+
+### 1.3 Branch Management (Enhanced)
+
+**BRANCH NAMING CONVENTION:**
+```
+feature/sprint-<id>-<goal-slug>
+```
+Examples:
+- `feature/sprint-01-barcode-print`
+- `feature/sprint-02-user-auth`
+- `feature/sprint-03-api-optimization`
+
+**BRANCH LIFECYCLE:**
+1. **Creation**: Branch from latest `main` with clean history
+2. **Development**: Regular commits following LUW pattern
+3. **Integration**: Rebase against `main` before completion
+4. **Handover**: All tests passing, documentation complete
+5. **Merge**: User responsibility, AI never merges
+
+### 1.4 Advanced Commit Strategies
+
+**RELATED CHANGE GROUPING:**
+```
+# Single commit for cohesive changes:
+feat(print): add barcode table with print optimization
+- Implement 3-column table layout for barcode display
+- Add CSS print media queries for A4 paper
+- Include responsive design for screen viewing
+- Add comprehensive i18n support (EN/HR)
+
+Refs: US-3, US-4
+```
+
+**DEPENDENCY TRACKING IN COMMITS:**
+```
+feat(auth): implement user session management
+
+Builds upon JWT middleware from previous commit.
+Requires database migration for session storage.
+
+Refs: US-5
+Depends-On: US-3 (JWT middleware)
+```
+
+---
+
+## 2. Enhanced Testing & Quality Assurance
+
+### 2.1 Multi-Level Testing Strategy
+
+**AUTOMATED TESTING (AI Responsibility):**

Subject: [PATCH 10/12] fix: resolve next-intl translation parameter error in
 print footer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix IntlError: FORMATTING_ERROR for print footer translation:

- Pass date parameter correctly to t("print-footer") in server component
- Remove manual string replacement in client component
- Use proper next-intl parameter syntax: t("key", { param: value })

Error was caused by next-intl expecting translation parameters
to be passed at the translation function call level, not through
manual string replacement afterward.

Print preview now loads without FORMATTING_ERROR and displays
localized footer text correctly in both English and Croatian.

Subject: [PATCH 11/12] feat: add multilingual support for print preview empty
 state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add i18n support for empty state when no barcode data is found:

**English translations:**
- "No Barcode Data Found"
- "No bills with 2D barcodes found for {yearMonth}"

**Croatian translations:**
- "Nema Podataka o Barkodovima"
- "Nema računa s 2D barkodovima za {yearMonth}"

**Implementation:**
- Add translation keys to messages/en.json and messages/hr.json
- Update server component to fetch empty state translations
- Use proper next-intl parameter passing for yearMonth variable
- Replace hardcoded English text with localized translations

Empty state now displays correct language based on URL locale:
- /en/print/2025/01 → English empty state message
- /hr/print/2025/01 → Croatian empty state message

Subject: [PATCH 12/12] fix: resolve MongoDB ObjectId serialization error in
 client components
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix React serialization warning when passing ObjectIds to client components:

**Problem:**
- MongoDB ObjectIds have toJSON() methods which React rejects in client components
- Error: "Only plain objects can be passed to Client Components from Server Components. Objects with toJSON methods are not supported"
- Occurred when rendering main page with year parameter (?year=2023)

**Solution:**
- Add $addFields stage in fetchAllLocations aggregation pipeline
- Convert location _id and bill _id fields to strings using $toString
- Simplify $project stage to use single "bills": 1 instead of individual field projections
- Ensures only plain objects (strings) are passed to client components

**Technical Details:**
- Modified app/lib/actions/locationActions.ts:268-287
- Added $addFields stage before existing $project stage
- Converted ObjectIds to strings while preserving all other data structures
- Build passes without serialization warnings

ObjectId serialization now handled properly across all client component boundaries.
