+# Issue Implementation
+
+Fully implement GitHub issues with autonomous execution after plan approval.
+
+## Usage
+
+```
+/implement <issue-number>
+```
+
+**Parameters:**
+- `issue-number`: GitHub issue number to implement
+
+## Description
+
+This command provides complete autonomous implementation of GitHub issues. After plan approval, it executes all implementation steps without user interaction until completion or hard blockers.
+
+## What it does
+
+1. **Preparation Phase:**
+   - Checks current branch name and compares with target: `marcuscastelo/issue<ISSUE_NUMBER>`
+   - If already on correct branch, skips branch creation/checkout
+   - If not on correct branch:
+     - Fetches and checks out latest `rc/` branch or default base
+     - Creates feature branch: `marcuscastelo/issue<ISSUE_NUMBER>`
+   - Retrieves issue data using `gh` CLI (title, body, labels, comments)
+   - Validates issue exists and is implementable
+
+2. **Planning Phase:**
+   - Analyzes issue requirements and acceptance criteria
+   - Checks referenced commits or working versions
+   - Drafts comprehensive implementation plan in Markdown
+   - Reviews plan with user and iterates until approved
+   - **Planning stops here - waits for explicit approval**
+
+3. **Implementation Phase (Post-Approval):**
+   - **Autonomous execution begins immediately**
+   - Makes all required code changes
+   - Fixes code style, type, and test issues as they arise
+   - Updates or rewrites tests to match changes
+   - Runs validation scripts until all pass
+   - Applies consistent patterns across codebase
+   - **No status updates or confirmations during execution**
+   - **Only stops for hard blockers or ambiguity**
+
+4. **Completion Validation:**
+   - Verifies all tests pass
+   - Confirms code quality checks pass (ESLint, Prettier, TypeScript)
+   - Ensures build succeeds
+   - Validates clean architecture preservation
+   - Commits all changes with proper conventional messages
+   - Confirms no uncommitted changes remain

+# Milestone Issue Prioritization and Deferral
+
+**Command:** `/prioritize-milestone`
+
+## Purpose
+
+This command analyzes a milestone's issues and helps prioritize them for the current milestone or defer them to the next milestone. It aims to maintain optimal milestone sizes (30-60 issues) while ensuring critical issues remain in the current milestone.
+
+## How It Works
+
+1. **Input**: Prompts for the milestone to analyze
+2. **Fetch Issues**: Uses `gh` CLI to list all issues assigned to the given milestone
+3. **Fetch Milestones**: Uses `gh` CLI to list all available milestones for user confirmation
+4. **Prioritization**:
+   - Analyzes and suggests which issues are most critical for the current milestone
+   - Suggests which issues can be deferred
+   - Clearly presents both lists to the user
+5. **Next Milestone Confirmation**:
+   - Shows available milestones from `gh` CLI
+   - Asks user to confirm which milestone should receive the deferred issues
+   - Confirms the deferral plan with the user before proceeding
+6. **Deferral Execution**:
+   - Upon confirmation, uses `gh` CLI to move all deferred issues to the next milestone
+   - Reports the changes made
+
+## Usage
+
+```bash
+/prioritize-milestone
+```
+
+The command will guide you through:
+- Selecting the milestone to analyze
+- Reviewing the prioritization suggestions
+- Confirming the next milestone for deferrals
+- Executing the deferral plan
+
+## Prioritization Criteria
+
+The command considers:
+- **Issue complexity** (based on labels like `complexity-low`, `complexity-medium`, `complexity-high`)
+- **Issue type** (bugs vs features vs improvements)
+- **Dependencies** between issues
+- **Current milestone capacity** (targeting 30-60 issues)
+
+## Interactive Flow
+
+1. **Milestone Selection**: Choose which milestone to analyze
+2. **Issue Analysis**: Review current issues and their classification
+3. **Prioritization Review**: Confirm which issues should stay vs be deferred
+4. **Target Milestone**: Select destination milestone for deferred issues
+5. **Execution**: Move issues and report results
+
+## Requirements
+
+- GitHub CLI (`gh`) must be installed and authenticated
+- Proper repository access for milestone management
+- Issues should be labeled according to project standards
+
+## Example Workflow
+
+1. User runs `/prioritize-milestone`
+2. Command prompts for milestone "Q3-2025"
+3. Command uses `gh` to list all issues in "Q3-2025"
+4. Command suggests which issues are priority and which can be deferred
+5. Command shows available milestones and asks user to confirm "Q4-2025" as next milestone
+6. Upon confirmation, command uses `gh` to move deferred issues and reports results
+
+## Output Format
+
+- All results displayed as Markdown
+- Clear separation between priority and deferral lists
+- Summary of changes made
+- Audit trail of decisions
+
+## Related Commands
+
+- `/create-issue` - Create new issues with proper labeling
+- `/implement` - Implement specific issues
+- `/review` - Review milestone readiness

+# GitHub Issue Refiner
+
+Refines existing GitHub issues by clarifying requirements, adding missing details, and ensuring they follow proper templates for optimal implementation.
+
+## Usage
+
+```
+/refine-issue <issue-number>
+```
+
+**Parameters:**
+- `issue-number` (required): GitHub issue number to refine
+
+## Description
+
+This command takes an existing GitHub issue and guides you through an interactive refinement process. It fetches the current issue content, analyzes it against project templates, and helps clarify any ambiguous or missing information to make the issue actionable for implementation.
+
+## What it does
+
+1. **Issue Retrieval:**
+   - Fetches issue content using `gh issue view --json` with all available fields
+   - Retrieves both issue body and all comments for complete context
+   - Validates issue exists and is accessible
+
+2. **Template Analysis:**
+   - Analyzes current issue content and structure
+   - Automatically deduces the most appropriate template from `docs/`:
+     - Bug: `ISSUE_TEMPLATE_BUGFIX.md`
+     - Feature: `ISSUE_TEMPLATE_FEATURE.md`  
+     - Improvement: `issue-improvement-*.md`
+     - Refactor: `ISSUE_TEMPLATE_REFACTOR.md`
+     - Task: `ISSUE_TEMPLATE_TASK.md`
+     - Subissue: `ISSUE_TEMPLATE_SUBISSUE.md`
+   - If template cannot be confidently determined, presents options to user
+
+3. **Interactive Refinement:**
+   - Prompts for missing or unclear information in each template field
+   - Asks clarifying questions to resolve ambiguities
+   - Ensures all acceptance criteria are explicit and actionable
+   - Confirms user intent for global/codebase-wide changes
+   - Suggests scope improvements and expected outcomes
+   - Validates technical feasibility and implementation approach
+
+4. **Content Enhancement:**
+   - Fills gaps in problem description and context
+   - Adds technical details and implementation hints
+   - Includes relevant file paths and code references
+   - Ensures issue is self-contained and LLM-friendly
+   - Adds traceability with `reportedBy` metadata
+
+5. **Label Management:**
+   - Analyzes current labels and suggests improvements
+   - Proposes additions based on refined content:
+     - Type labels: `bug`, `feature`, `improvement`, `refactor`, `task`, `subissue`
+     - Complexity: `complexity-low`, `complexity-medium`, `complexity-high`, `complexity-very-high`
+     - Area: `ui`, `backend`, `api`, `performance`, `data-consumption`, `accessibility`
+     - Status: `blocked`, `needs-investigation`, `needs-design`
+   - Confirms with user before applying label changes
+   - Removes generic or conflicting labels
+
+6. **Issue Update:**
+   - Structures refined content according to selected template
+   - Uses Markdown formatting for consistency
+   - Writes issue body to temporary file using heredoc
+   - Updates issue using `gh issue edit --body-file`
+   - Applies label changes in same workflow
+   - Handles CLI errors gracefully with automatic retries

+# Codebase Quality Fix
+
+Automatically run comprehensive checks and fix all detected issues until the codebase passes all quality gates.
+
+## Usage
+
+```
+/fix
+```
+
+## Description
+
+This command performs automated codebase checks using `npm run copilot:check` and fixes all detected issues including linting errors, type errors, and test failures. It continues iterating until all checks pass.
+
+## What it does
+
+1. **Check Execution:**
+   - Runs `npm run copilot:check` with output redirection
+
+2. **Output Validation:**
+   - Checks for "COPILOT: All checks passed!" success message
+   - Detects error patterns: `failed`, `at constructor`, `error`, `replace`
+   - Never stops early - completes all validation scripts
+
+3. **Error Analysis:**
+   - Analyzes detected issues using agent capabilities
+   - Categorizes errors by type (lint, type, test, build)
+   - Prioritizes fixes by impact and dependencies
+
+4. **Automated Fixes:**
+   - **Linting errors:** Auto-fixes with ESLint rules
+   - **Type errors:** Adds proper types and null checks
+   - **Import issues:** Converts to absolute imports with ~/
+   - **Test failures:** Updates tests for code changes
+   - **Formatting:** Applies Prettier consistently
+
+5. **Iteration Loop:**
+   - Re-runs full check process after each fix
+   - Continues until "COPILOT: All checks passed!" appears
+   - Never skips validation reruns
+
+## Fix Categories
+
+### ESLint Fixes
+- **Absolute imports:** Converts relative imports to `~/` format
+- **Type safety:** Adds explicit null/undefined checks
+- **Unused variables:** Removes or prefixes with underscore

+# Clean Architecture Refactoring
+
+Refactor code to follow clean architecture principles with proper layer separation and modularization.
+
+## Usage
+
+```
+/refactor [target] [scope]
+```
+
+**Parameters:**
+- `target` (optional): Specific file, component, or module to refactor
+- `scope` (optional): full, module, component, or function-level refactoring
+
+## Description
+
+This command performs comprehensive refactoring to ensure clean architecture compliance, proper modularization, and code quality improvements for SolidJS/TypeScript projects.
+
+## What it does
+
+1. **Architecture Analysis:**
+   - Analyzes current code structure and layer violations
+   - Identifies domain, application, and infrastructure concerns
+   - Detects cross-layer dependencies and violations
+
+2. **Clean Architecture Enforcement:**
+   - Ensures domain layer purity (no side effects)
+   - Validates application layer orchestration
+   - Confirms infrastructure layer isolation
+   - Fixes layer boundary violations
+
+3. **Modularization:**
+   - Extracts duplicated logic into reusable utilities
+   - Separates UI concerns from business logic
+   - Creates proper module boundaries
+   - Establishes clear dependency flows
+
+4. **Code Quality Improvements:**
+   - Applies consistent naming conventions
+   - Removes code duplication
+   - Improves type safety
+   - Optimizes performance patterns
+
+5. **Validation:**
+   - Runs comprehensive quality checks
+   - Ensures tests pass after refactoring
+   - Validates clean architecture compliance
+   - Confirms performance improvements
+
+## Clean Architecture Layers
+
+### Domain Layer (`modules/*/domain/`)
+
+**Rules:**
+- **Pure logic only** - No side effects
+- **Never call `handleApiError`** - Only throws pure errors
+- **No external dependencies** - Framework-agnostic code
+- **Business rules** - Core business logic and entities
+
+**Refactoring Actions:**
+```typescript
+// Before: Domain with side effects
+export function updateDayDiet(dayDiet: DayDiet) {
+  handleApiError(new Error('Invalid'), { component: 'domain' }) // ❌
+  toast.success('Updated') // ❌
+  return dayDiet
+}
+
+// After: Pure domain logic
+export function updateDayDiet(dayDiet: DayDiet): DayDiet {
+  if (!isValidDayDiet(dayDiet)) {
+    throw new Error('Invalid day diet', { cause: { dayDiet } }) // ✅
+  }
+  return dayDiet
+}
+```
+
+### Application Layer (`modules/*/application/`)
+
+**Rules:**
+- **Orchestrates domain logic** - Coordinates between layers
+- **Handles all side effects** - API calls, error handling, toasts
+- **Catches domain errors** - Always calls `handleApiError` with context
+- **State management** - SolidJS signals and effects
+
+**Refactoring Actions:**
+```typescript
+// Before: Application without error handling
+export function useDayDietUpdater() {
+  const updateDayDiet = (dayDiet: DayDiet) => {
+    return updateDayDietInRepository(dayDiet) // ❌ No error handling
+  }
+  return { updateDayDiet }
+}
+
+// After: Proper application orchestration
+export function useDayDietUpdater() {
+  const updateDayDiet = async (dayDiet: DayDiet) => {
+    try {
+      const validatedDayDiet = validateDayDiet(dayDiet) // Domain call
+      const result = await updateDayDietInRepository(validatedDayDiet)
+      toast.success('Day diet updated successfully')
+      return result
+    } catch (e) {
+      handleApiError(e, {
+        component: 'DayDietUpdater',
+        operation: 'updateDayDiet',
+        additionalData: { dayDietId: dayDiet.id }
+      })
+      throw e
+    }
+  }
+  return { updateDayDiet }
+}
+```
+
+### UI Layer (`sections/`, `components/`)
+
+**Rules:**
+- **Rendering only** - Delegates logic to hooks and utilities
+- **No direct side effects** - Uses application layer hooks
+- **Presentational focus** - UI concerns only
+
+**Refactoring Actions:**
+```typescript
+// Before: UI with business logic
+export function DayDietCard(props: { dayDiet: DayDiet }) {
+  const handleUpdate = () => {
+    // Complex business logic in UI ❌
+    if (props.dayDiet.calories > 2000) {
+      updateDayDiet({ ...props.dayDiet, status: 'complete' })
+    }
+  }
+  return <div onClick={handleUpdate}>...</div>
+}
+
+// After: UI delegates to application layer
+export function DayDietCard(props: { dayDiet: DayDiet }) {
+  const { updateDayDiet } = useDayDietUpdater() // Application layer hook
+  
+  const handleUpdate = () => void updateDayDiet(props.dayDiet)
+  
+  return <div onClick={handleUpdate}>...</div>
+}
+```
+
+## Modularization Patterns
+
+### Extract Utilities
+```typescript
+// Before: Duplicated logic
+export function ComponentA() {
+  const formatMacros = (carbs: number, protein: number, fat: number) => {
+    return `${carbs}g C, ${protein}g P, ${fat}g F` // Duplicated
+  }
+}
+
+export function ComponentB() {
+  const formatMacros = (carbs: number, protein: number, fat: number) => {
+    return `${carbs}g C, ${protein}g P, ${fat}g F` // Duplicated
+  }
+}
+
+// After: Extracted utility
+// ~/shared/utils/macroFormatting.ts
+export function formatMacroNutrients(macros: MacroNutrients): string {
+  return `${macros.carbs}g C, ${macros.protein}g P, ${macros.fat}g F`
+}
+```
+
+### Extract Hooks
+```typescript
+// Before: Logic in component
+export function MealEditor() {
+  const [meal, setMeal] = createSignal<Meal>()
+  const [loading, setLoading] = createSignal(false)
+  
+  const saveMeal = async () => {
+    setLoading(true)
+    try {
+      await mealRepository.save(meal())
+      toast.success('Meal saved')
+    } catch (e) {
+      handleApiError(e, { component: 'MealEditor' })
+    } finally {
+      setLoading(false)
+    }
+  }
+}
+
+// After: Extracted hook
+// ~/modules/diet/meal/application/useMealEditor.ts
+export function useMealEditor() {
+  const [meal, setMeal] = createSignal<Meal>()
+  const [loading, setLoading] = createSignal(false)
+  
+  const saveMeal = async () => {
+    setLoading(true)
+    try {
+      await mealRepository.save(meal())
+      toast.success('Meal saved')
+    } catch (e) {
+      handleApiError(e, {
+        component: 'MealEditor',
+        operation: 'saveMeal',
+        additionalData: { mealId: meal()?.id }
+      })
+    } finally {
+      setLoading(false)
+    }
+  }
+  
+  return { meal, setMeal, loading, saveMeal }
+}
+```
+
+## Performance Optimization
+
+### Algorithmic Improvements
+```typescript
+// Before: O(n²) filtering
+export function groupWeightsByPeriod(weights: Weight[]) {
+  return periods.map(period => ({
+    period,
+    weights: weights.filter(w => isInPeriod(w, period)) // O(n²)
+  }))
+}
+
+// After: O(n) sliding window
+export function groupWeightsByPeriod(weights: Weight[]) {
+  const groups: WeightGroup[] = []
+  let currentGroup: Weight[] = []
+  let periodIndex = 0
+  
+  for (const weight of weights) {
+    while (periodIndex < periods.length && !isInPeriod(weight, periods[periodIndex])) {
+      if (currentGroup.length > 0) {
+        groups.push({ period: periods[periodIndex], weights: currentGroup })
+        currentGroup = []
+      }
+      periodIndex++
+    }
+    currentGroup.push(weight)
+  }
+  
+  return groups
+}
+```
+
+## Import and Module Fixes
+
+### Absolute Import Conversion
+```typescript
+// Before: Relative imports
+import { DayDiet } from '../../domain/dayDiet' // ❌
+import { handleApiError } from '../../../shared/error/errorHandler' // ❌
+
+// After: Absolute imports
+import { DayDiet } from '~/modules/diet/day-diet/domain/dayDiet' // ✅
+import { handleApiError } from '~/shared/error/errorHandler' // ✅
+```
+
+### Static Import Enforcement
+```typescript
+// Before: Dynamic imports
+const loadComponent = async () => {
+  const { Component } = await import('./Component') // ❌
+  return Component
+}
+
+// After: Static imports with lazy loading
+import { lazy } from 'solid-js'
+const Component = lazy(() => import('./Component')) // ✅
+```
+
+## Validation Process
+
+### Quality Checks
+1. **Run comprehensive checks:**
+   ```bash
+   npm run copilot:check | tee /tmp/copilot-terminal 2>&1
+   ```
+
+2. **Verify success message:**
+   - Must see "COPILOT: All checks passed!"
+   - Check with `.scripts/cat1.sh`, `.scripts/cat2.sh`, `.scripts/cat3.sh`
+
+3. **Architecture validation:**
+   - No cross-layer violations
+   - Proper error handling patterns
+   - Clean import structure
+
+### Test Updates
+- Update tests for refactored code
+- Remove orphaned tests
+- Add tests for new utilities
+- Ensure all tests pass
+
+## Commit Strategy
+
+### Atomic Commits
+```bash
+git commit -m "refactor(day-diet): extract domain validation logic"
+git commit -m "refactor(day-diet): move error handling to application layer"
+git commit -m "refactor(day-diet): create reusable formatting utilities"
+```
+
+### Conventional Commit Types
+- `refactor(scope): description` - Code restructuring
+- `perf(scope): description` - Performance improvements
+- `style(scope): description` - Code style improvements
+- `test(scope): description` - Test updates
+
+## Requirements
+
+- Write access to codebase

+# Commit Message Generator
+
+Analyze staged changes and generate a conventional commit message in English, then execute the commit.
+
+## Usage
+
+```
+/commit
+```
+
+## Description
+
+This command analyzes the current staged git changes and generates a conventional commit message following the project's standards. It will automatically commit the changes after generating the message.
+
+## What it does
+
+1. **Verification Phase:**
+   - Runs `scripts/copilot-commit-info.sh` to gather git information
+   - Checks if there are staged changes to commit
+   - Stops if no staged changes are found
+
+2. **Analysis Phase:**
+   - Analyzes staged changes from script output
+   - Determines the type of changes (feat, fix, refactor, etc.)
+   - Identifies affected modules and components
+
+3. **Generation Phase:**
+   - Creates a conventional commit message in English
+   - Ensures message is atomic and describes the main change
+   - Follows format: `type(scope): description`
+
+4. **Execution Phase:**
+   - Displays the generated commit message
+   - Executes the commit automatically
+   - Uses proper shell escaping for multi-line messages
+
+## Requirements
+
+- Staged git changes must exist
+- `scripts/copilot-commit-info.sh` script must be available
+- Git repository must be properly initialized
+
+## Output Format
+
+The command outputs the commit message in a markdown code block:
+
+````markdown
+feat(day-diet): add copy previous day functionality
+````
+
+Then executes:
+```bash
+git commit -m "feat(day-diet): add copy previous day functionality"
+```
+
+## Commit Message Rules
+
+- **Language:** Always in English
+- **Format:** Conventional commits style (type(scope): description)
+- **Types:** feat, fix, refactor, test, chore, docs, style, perf, ci
+- **Scope:** Module or component name when applicable
+- **Description:** Clear, concise summary of the main change
+- **Security:** Never include sensitive data, code diffs, or secrets
+- **Atomicity:** One logical change per commit
+
+## Error Handling
+
+- No staged changes: Warns user to stage changes first
+- Script failures: Reports issue and suggests manual verification
+- Shell errors: Uses file-based commit for complex messages
+- Permission issues: Provides troubleshooting guidance
+
+## Project-Specific Rules
+
+- References affected modules from src/modules/ structure
+- Follows clean architecture layer naming
+- Respects domain-driven design terminology
+- Maintains consistency with existing commit history

+
+2. Memory Retrieval:
+   - Always begin your chat by saying only "Remembering..." and retrieve all relevant information from your knowledge graph

+4. Memory Update:
+   - If any new information was gathered during the interaction, update your memory as follows:
+     a) Create entities for recurring organizations, people, and significant events
+     b) Connect them to the current entities using relations
+     b) Store facts about them as observations

+## Project Context Detection and Solo Project Adaptations
+
+Before suggesting team-related processes, verify project context:
+- Does the project have multiple active developers? (check git commits, team references)
+- Are there stakeholders mentioned in documentation?
+- Is there evidence of formal approval processes?
+
+### Solo Project Adaptations
+When working on solo projects (no stakeholders, minimal users, single developer):
+- Remove all team collaboration, stakeholder communication, and user feedback collection requirements
+- Maintain technical quality standards (testing, monitoring, backup procedures)
+- Focus on technical validation rather than approval processes
+- Adapt checklists to remove coordination tasks while preserving verification steps
+- Simplify metrics to focus on technical rather than business/team indicators
+- Replace peer review with systematic self-review processes
+- Focus on automated validation rather than manual coordination
+- Preserve backup/rollback procedures without team communication requirements
+
+### Quality Standards Adaptation
+For solo projects:
+- Maintain technical quality (testing, monitoring, error handling)
+- Replace peer review with systematic self-review processes
+- Focus on automated validation rather than manual coordination
+- Preserve backup/rollback procedures without team communication requirements
+
+### Documentation Generation for Solo Projects
+- Detect project type (solo vs team) early in the session
+- Generate context-appropriate sections
+- Provide solo-specific templates and examples
+- Avoid generating team-coordination content for solo projects
+- Remove approval and communication workflows
+- Focus on technical validation and self-review processes

 # Issue Implementation Agent
 
-Your task is to fully automate the implementation of a GitHub issue, from preparation to execution, with **no interruptions after plan approval**.
+Your job is to fully implement GitHub issues with **no user interaction after the plan is approved**.
 
 ## Workflow
 
-1. **Checkout Base Branch**
-   - Run `git fetch` to update the local repository.
-   - Identify and checkout the latest `rc/` remote branch (e.g., `origin/rc/v0.12.0`) or use the default remote branch.
-
-2. **Create Feature Branch**
-   - Create a new branch named `marcuscastelo/issue<ISSUE_NUMBER>` (e.g., `marcuscastelo/issue711`).
-
-3. **Fetch Issue Details**
-   - Use GitHub CLI (`gh`) to retrieve issue title, body, labels, and comments.
-
-4. **Understand and Plan**
-   - Analyze the issue and related context.
-   - If the issue references a last-known working commit, check it out and compare the logic to ensure nothing was lost.
-   - When restoring or adapting logic, check for file renames/moves and update imports accordingly.
-   - Preserve all usages of the feature logic across the codebase.
-   - Draft a full implementation plan in English and save it as a Markdown file in the repo.
-   - Brainstorm and iterate with the user until the plan is approved.
-
-5. **Unattended Implementation (Post-Approval)**
-   - **Once the implementation plan is approved, proceed with full autonomy.**
-   - **Do not request permission, confirmations, or provide status updates. Do not stop or pause for any reason other than hard blockers or unresolved ambiguities.**
-   - Execute each step of the plan in sequence.
-   - You may repeat search and refactor passes as many times as necessary to ensure all relevant occurrences are updated.
-   - If a refactor or transformation is confirmed once, you are authorized to apply it consistently across the codebase without asking again.
-   - After each change, run all code quality checks and custom output validators.
-   - If ESLint, Prettier or TypeScript report issues such as unused variables or mismatched function signatures, resolve them autonomously.
-   - Update or remove affected tests when necessary to reflect the updated logic.
-   - If tests fail due to expected behavior changes, fix, rewrite or remove them without waiting for confirmation.
-   - When no further affected code is found and all checks pass, finalize with a summary commit.
-   - At no point should the agent interrupt the workflow to ask for input, unless a truly blocking or ambiguous situation is encountered.
-
-## Success Criteria & Completion Validation
-
-**Implementation is considered complete when ALL of the following conditions are met:**
-
-1. **Code Quality Validation**
-   - Run `npm run copilot:check | tee /tmp/copilot-terminal-[N] 2>&1`
-   - Execute validation scripts in sequence: `.scripts/cat1.sh`, `.scripts/cat2.sh`, `.scripts/cat3.sh`
-   - Continue until "COPILOT: All checks passed!" appears or all 3 checks complete
-   - No ESLint, Prettier, or TypeScript errors remain
-   - All imports are resolved and static
-
-2. **Functional Validation**
-   - All tests pass (`npm test` or equivalent)
-   - Application builds successfully
-   - No runtime errors in affected features
-   - All issue requirements are demonstrably met
-
-3. **Architecture Compliance**
-   - Clean architecture principles maintained (domain/application separation)
-   - Error handling follows project patterns (handleApiError usage)
-   - No `.catch(() => {})` or dynamic imports introduced
-   - All code and comments in English
-
-4. **Git State Validation**
-   - All changes committed with conventional commit messages
-   - Branch is ready for merge (no conflicts with base)
-   - No uncommitted changes remain
-   - Summary commit describes the full transformation
-
-**Only declare success after ALL criteria are verified. If any criterion fails, continue implementation until resolved.**
-
-## Enhanced Error Handling & Recovery
-
-### Hard Blockers (Stop and Request User Input)
-1. **Ambiguous Requirements**: Issue description contradicts existing code/architecture
-2. **Missing Dependencies**: Required APIs, libraries, or external services not available
-3. **Merge Conflicts**: Cannot resolve conflicts with base branch automatically
-4. **Breaking Changes**: Implementation would break existing functionality without clear guidance
-5. **Security Concerns**: Changes involve authentication, authorization, or data sensitivity
-6. **Infrastructure Dependencies**: Requires database migrations, environment changes, or deployment updates
-
-### Soft Blockers (Attempt Recovery, Max 3 Tries)
-1. **Test Failures**: Try fixing tests, rewriting expectations, or removing obsolete tests
-2. **Linting Errors**: Auto-fix with ESLint/Prettier, update imports, resolve type issues
-3. **Build Failures**: Resolve missing imports, type mismatches, syntax errors
-4. **Validation Script Failures**: Retry with corrections, check for transient issues
-5. **File Not Found**: Search for moved/renamed files, update paths and imports
-
-### Recovery Strategies
-- **For each soft blocker**: Document the issue, attempt fix, validate, repeat (max 3 attempts)
-- **If recovery fails**: Escalate to hard blocker status and request user input
-- **For validation failures**: Always run the full validation sequence after fixes
-- **For git issues**: Use `git status` and `git diff` to understand state before recovery attempts
-
-### Error Context Documentation
-When encountering any blocker:
-1. Clearly state the specific error/issue encountered
-2. Describe what was attempted for resolution
-3. Provide relevant error messages, file paths, or git status
-4. Explain why user input is required (for hard blockers only)
-
-## Behavior Rules
-
-- After plan approval, the agent becomes fully autonomous.
-- Absolutely no user prompts, confirmations, status messages, or progress updates are required during implementation.
-- Outputting commit messages or progress is optional, not required.
-- The agent must not wait for user input after plan approval, except for hard blockers as defined in Error Handling section.
-- The agent should only stop when all Success Criteria are met or when a hard blocker is encountered.
-- Always validate completion using the full Success Criteria checklist before declaring success.
-
-## Code and Commit Standards
-
-- All code, comments, and commits must be in English.
-- Use static imports only.
-- Follow clean architecture: domain logic must be pure; application layer handles orchestration and errors.
-- Never use dynamic imports or `.catch(() => {})`.
-- Do not add unnecessary explanatory comments.
-- Run Prettier and ESLint on all changes.
-- Convert non-English code comments to English or flag them for review.
-- UI strings can be in English or pt-BR depending on feature scope.
-- Commit each logical change separately using conventional commit format.
-- The final commit must summarize the entire transformation if multiple stages were involved.
-
-## Output Format
-
-- Output the implementation plan as a Markdown code block.
-- Outputting commit messages or progress is optional, not required.
-- Do not output anything else during implementation after the plan is approved, unless a hard blocker is encountered.
-- When complete, confirm that all Success Criteria have been met with a brief summary.
+1. **Preparation**
+   - Fetch and check out the latest `rc/` branch or the default base branch.
+   - Create a feature branch: `marcuscastelo/issue<ISSUE_NUMBER>`.
+   - Use `gh` to retrieve issue data (title, body, labels, comments).
+
+2. **Planning**
+   - Understand the issue. Check last-known working commits if referenced.
+   - Draft a full implementation plan in Markdown.
+   - Brainstorm and revise with the user until approved.
+
+3. **Implementation (After Plan Approval)**
+   - Begin implementation immediately.
+   - Make all required code changes.
+   - Fix code style, type, and test issues as they appear.
+   - Update or rewrite tests as needed.
+   - Run all validation scripts until they pass.
+   - Apply consistent patterns across codebase once confirmed.
+   - Never output status, confirmations, or commit messages during execution.
+   - Only stop for hard blockers or ambiguity.
+
+4. **Completion**
+   - Validate success via:
+     - All tests pass.
+     - Code quality (ESLint, Prettier, TS) passes.
+     - Build succeeds.
+     - Clean architecture preserved.
+     - All changes committed with proper messages.
+     - No uncommitted changes remain.
+
+5. **Blockers**
+   - **Hard blockers (stop and ask user):** ambiguous requirements, missing dependencies, breaking changes, infra issues.
+   - **Soft blockers (retry up to 3x):** test/lint/build/validation failures, missing files.
+
+## Rules
+
+- Never wait or pause after plan approval.
+- Never output anything during implementation unless blocked.
+- Only stop when fully complete or blocked.
+- Final output must confirm that all success criteria were met.

+# Architecture and Code Structure
+
+## Clean Architecture Pattern
+The project follows a strict 3-layer Domain-Driven Design (DDD) architecture:
+
+### 1. Domain Layer (`modules/*/domain/`)
+- **Purpose**: Pure business logic, types, and repository interfaces
+- **Characteristics**: 
+  - Framework-agnostic
+  - Uses Zod schemas for validation and type inference
+  - Entities have `__type` discriminators for type safety
+  - NEVER imports side-effect utilities (handleApiError, logging, toasts)
+  - Only throws pure domain errors with context
+
+### 2. Application Layer (`modules/*/application/`)
+- **Purpose**: SolidJS resources, signals, and orchestration logic
+- **Characteristics**:
+  - Must always catch domain errors and call `handleApiError` with full context
+  - Manages global reactive state using `createSignal`/`createEffect`
+  - Coordinates between UI and infrastructure layers
+  - Handles all side effects and user feedback (toasts, notifications)
+
+### 3. Infrastructure Layer (`modules/*/infrastructure/`)
+- **Purpose**: Supabase repositories implementing domain interfaces
+- **Characteristics**:
+  - DAOs for data transformation and legacy migration
+  - External API integrations and data access
+  - Only layer allowed to use `any` types when necessary for external APIs

+# Code Style and Conventions
+
+## Import and Module System
+- **REQUIRED**: Always use absolute imports with `~/` prefix
+- **FORBIDDEN**: Relative imports (`../`, `./`)
+- **FORBIDDEN**: Barrel files (`index.ts` re-exports)
+- **REQUIRED**: Static imports at top of file
+- **REQUIRED**: Type imports with inline syntax: `import { type Foo } from '~/module'`
+
+## Language Policy
+- **All code, comments, JSDoc, and commit messages in English**
+- **UI text only may be in Portuguese (pt-BR) when required**
+- **Never use Portuguese for identifiers, variables, functions, or comments**
+
+## Naming Conventions
+- **Descriptive, action-based names**: `isRecipedGroupUpToDate()` not `checkGroup()`
+- **Specific file names**: `macroOverflow.ts` not `utils.ts`
+- **Complete component names**: `ItemGroupEditModal` not `GroupModal`
+- **Avoid generic names**: Never use `utils.ts`, `helper.ts`, `common.ts`
+
+## Type Safety Requirements
+- **NEVER use `any`, `as any`, or `@ts-ignore`** (except infrastructure layer for external APIs)
+- **Always prefer type aliases over interfaces** for data shapes
+- **Use Zod schemas for runtime validation and type inference**
+- **Prefer `readonly` arrays**: `readonly Item[]` over `Item[]`
+- **Use intersection types for extending**: `ConfigType = PropsType & { extraProps }`
+- **Default parameters over nullish coalescing**: `{ param = 'default' }` instead of `param ?? 'default'`
+
+## Error Handling Standards
+- **Domain Layer**: Only throw pure domain errors with context
+- **Application Layer**: Always catch domain errors and call `handleApiError` with context
+- **Error Context Requirements**:
+  - `component`: Specific component/module name
+  - `operation`: Specific operation being performed
+  - `additionalData`: Relevant IDs, state, or debugging info
+
+## ESLint Rules
+- **Consistent type definitions**: Use `type` not `interface`
+- **Import organization**: Automatic sorting with `simple-import-sort`
+- **No relative imports**: Enforced by `no-restricted-imports` rule
+- **Strict boolean expressions**: Enforced for better type safety
+- **Custom parsing requirement**: Use `parseWithStack` instead of direct `JSON.parse`
+
+## CSS and Styling
+- **Always use `cn` function to merge Tailwind classes** for proper deduplication
+- **TailwindCSS v4.1.8** with DaisyUI v5.0.43 for component styling

+# Test Documentation Framework
+
+## Testing Strategy Overview
+
+Macroflows uses a comprehensive testing strategy with Vitest and jsdom for unit and integration tests. Tests are organized by module and layer, following the clean architecture pattern.
+
+## Test Organization Structure
+
+### 1. **Test Location Patterns**
+- **Module tests**: `src/modules/{module}/tests/` or alongside source files with `.test.ts` suffix
+- **Domain tests**: Focus on business logic validation and error handling
+- **Application tests**: Test SolidJS resources, state management, and orchestration
+- **Infrastructure tests**: Test database operations, migrations, and external integrations
+
+### 2. **Test Types by Layer**
+
+#### Domain Layer Tests
+- **Focus**: Pure business logic, validation, and domain operations
+- **Examples**:
+  - `dayDietOperations.test.ts` - Day diet business logic
+  - `recipeOperations.test.ts` - Recipe scaling and operations
+  - `itemGroupOperations.test.ts` - Item group management
+  - `mealOperations.test.ts` - Meal operations
+- **Patterns**: Pure function testing, validation testing, error condition testing
+
+#### Application Layer Tests
+- **Focus**: SolidJS reactive state, orchestration, and error handling
+- **Examples**:
+  - `dayDiet.test.ts` - Day diet state management
+  - `item.test.ts` - Item application services
+  - `template.test.ts` - Template application services
+- **Patterns**: Signal testing, effect testing, error handling validation
+
+#### Infrastructure Layer Tests

+- **Examples**:
+  - `dayDietDAO.test.ts` - DAO conversions and legacy migration
+  - `migrationUtils.test.ts` - Data migration utilities
+- **Patterns**: DAO testing, migration testing, repository testing
+
+### 3. **Specialized Test Categories**
+
+#### Schema and Validation Tests
+- **Examples**:
+  - `unifiedItemSchema.test.ts` - Complex type validation
+  - `validateItemHierarchy.test.ts` - Hierarchy validation
+- **Focus**: Zod schema validation, type guards, data integrity
+
+#### Utility Function Tests
+- **Examples**:
+  - `measureUtils.test.ts` - Measurement calculations
+  - `conversionUtils.test.ts` - Type conversions
+  - `treeUtils.test.ts` - Tree operations
+- **Focus**: Pure utility functions, calculations, transformations
+
+#### Error Handling Tests
+- **Examples**:
+  - `errorMessageHandler.test.ts` - Error message processing
+  - `clipboardErrorUtils.test.ts` - Clipboard error handling
+- **Focus**: Error processing, message formatting, error recovery
+
+#### Toast System Tests

+- **Given-When-Then structure**: Clear test organization
+- **Expected behavior**: Explicit assertions and expectations
+- **Error scenarios**: Expected error conditions and messages
+
+### 3. **Mock and Setup Documentation**
+- **Mock purposes**: Why mocks are used and what they simulate
+- **Setup functions**: Reusable test setup utilities
+- **Test data**: Well-structured test data factories
+
+## Testing Standards
+
+### 1. **Coverage Requirements**
+- **Domain layer**: 100% coverage of business logic
+- **Application layer**: Focus on error handling and state management
+- **Infrastructure layer**: Test DAO conversions and migrations
+
+### 2. **Test Quality Standards**
+- **Isolated tests**: Each test should be independent
+- **Deterministic**: Tests should produce consistent results
+- **Fast execution**: Tests should run quickly
+- **Clear assertions**: Explicit and meaningful assertions
+
+### 3. **Test Maintenance**
+- **Update with changes**: Tests must be updated when code changes
+- **Remove orphaned tests**: Delete tests for removed functionality
+- **Refactor with code**: Keep tests aligned with code structure
+
+## Common Test Patterns
+
+### 1. **Domain Entity Testing**
+```typescript
+describe('Entity Operations', () => {
+  it('should create valid entity', () => {
+    // Test entity creation
+  })
+  
+  it('should validate entity constraints', () => {
+    // Test validation rules
+  })
+  
+  it('should handle invalid input', () => {
+    // Test error conditions
+  })
+})
+```
+
+### 2. **Application State Testing**
+```typescript
+describe('Application State', () => {
+  beforeEach(() => {
+    // Setup mocks and initial state
+  })
+  
+  it('should handle state updates', () => {
+    // Test reactive state changes
+  })
+  
+  it('should handle errors correctly', () => {
+    // Test error handling and recovery
+  })
+})
+```
+
+### 3. **Infrastructure Testing**
+```typescript
+describe('Infrastructure Operations', () => {
+  it('should convert DAO to entity', () => {
+    // Test data conversion
+  })
+  
+  it('should handle migration scenarios', () => {
+    // Test data migrations
+  })
+})
+```

+# Testing and Quality Commands
+
+## 🚨 MANDATORY Quality Gate
+**CRITICAL REQUIREMENT: ALWAYS RUN `pnpm check` BEFORE DECLARING ANY TASK COMPLETE**
+
+## Essential Commands
+- `pnpm check` - **MANDATORY** quality gate (lint, type-check, test) - MUST PASS before any completion
+- `pnpm fix` - Auto-fix ESLint issues
+- `pnpm flint` - Fix then lint (fix + lint)
+
+## Granular Commands
+- `pnpm build` - Production build (runs gen-app-version first)
+- `pnpm type-check` - TypeScript type checking
+- `pnpm test` - Run all tests with Vitest
+- `pnpm lint` - ESLint checking (quiet mode)
+
+## Development Commands
+- `pnpm dev` - Start development server
+- `pnpm gen-app-version` - Generate app version from git
+
+## Testing Framework
+- **Testing Library**: Vitest v3.2.2 with jsdom environment
+- **Test Location**: Module `tests/` folder or alongside source with `.test.ts` suffix
+- **Coverage**: `pnpm test --coverage`
+- **Single Test**: `pnpm test <file-pattern>`
+
+## Testing Requirements
+- **Always update tests when changing code**
+- **Remove orphaned tests** - no tests for deleted functionality
+- Mock dependencies explicitly for domain/application logic
+- Tests must pass before any task completion
+
+## Pre-Commit Requirements
+**⛔ CRITICAL RULE: NEVER declare any implementation, fix, or feature "complete" without:**
+1. Running `pnpm check` and verifying ALL checks pass
+2. Confirming NO TypeScript errors
+3. Confirming NO ESLint errors
+4. Confirming ALL tests pass
+5. Only then can you say "✅ COMPLETE"
+
+## Comprehensive Validation
+- `pnpm copilot:check` - Must show "COPILOT: All checks passed!" for full validation

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Macroflows is a nutrition tracking platform built with SolidJS, TypeScript, and Supabase. It follows domain-driven design principles with a layered architecture and emphasizes type safety, reactive programming, and modular organization.
+
+**Project Context:** This is a solo project by marcuscastelo - adapt all suggestions to remove team coordination/approval processes while maintaining technical quality.
+
+## Frontend Simplicity Principles - CRITICAL
+
+**🚨 THIS IS A FRONTEND APP, NOT A LIBRARY**
+
+### Anti-Over-Engineering Rules
+
+**Never Add These Patterns:**
+- **Custom Error Classes**: Use standard `Error()` + Zod validation instead
+- **Abstract Base Classes**: Avoid unless there are 3+ concrete implementations
+- **Domain-Specific Exceptions**: Use descriptive error messages, not error types
+- **Complex Hierarchies**: Prefer composition over inheritance
+- **Enterprise Patterns**: This is a solo project - keep it simple
+
+**Frontend Reality Check:**
+- Most errors come from network/API calls, not business logic violations
+- Zod provides excellent validation without custom error classes
+- Standard `Error()` + good error handling functions are sufficient
+- TypeScript provides compile-time safety - runtime errors should be simple
+- Users don't care about your error taxonomy - they care about clear messages
+
+### Before Adding Any Abstraction, Ask:
+
+- [ ] **Multiple implementations**: Will this pattern have 3+ different implementations?
+- [ ] **Real problem**: Does this solve a problem we actually have (not might have)?
+- [ ] **Platform sufficiency**: Is standard web platform functionality insufficient?
+- [ ] **Library vs App**: Are we building a reusable library or a specific frontend app?
+- [ ] **Lines of code**: Will this reduce or increase total lines of code?
+- [ ] **Maintenance burden**: Will future developers thank us or curse us for this?
+
+**Golden Rule**: If you can't immediately name 3 different concrete implementations of your abstraction, don't create it.
+
+## Rapid Implementation Guidelines - CRITICAL
+
+**🚀 SPEED COMES FROM SAYING NO TO UNNECESSARY COMPLEXITY**
+
+### Implementation Velocity Principles
+
+**Never Add These Unless Absolutely Essential:**
+- **Backward Compatibility**: Frontend is versioned - Vercel rollback solves problems
+- **Feature Flags**: Just implement the feature directly
+- **A/B Testing Infrastructure**: Manual testing is sufficient for most cases
+- **Fallback Mechanisms**: Trust your implementation and monitoring
+- **Migration Strategies**: Direct replacement with proper testing
+- **Enterprise Rollout Plans**: This is a solo project with simple deployment
+
+**Speed-First Decision Framework:**
+- [ ] **Direct implementation**: Can we just build the feature without scaffolding?
+- [ ] **Platform leverage**: Are we using database/framework strengths optimally?
+- [ ] **Delete over add**: Can we remove complexity instead of adding abstraction?
+- [ ] **Server-side logic**: Should this logic live in PostgreSQL instead of TypeScript?
+- [ ] **Testing necessity**: Does this need a test or does TypeScript/DB already guarantee it?
+
+### Logic Placement Hierarchy (Most to Least Preferred)
+
+1. **PostgreSQL Functions (RPC)**: For search, data processing, complex queries
+2. **Domain Layer**: Pure business logic, validations, calculations  
+3. **Application Layer**: SolidJS orchestration, error handling, UI state
+4. **Infrastructure Layer**: External API calls, data transformation
+
+**Example Decision Tree:**
+```typescript
+// ❌ Complex: Spread across layers
+// Client: word splitting + normalization
+// Server: multiple API calls + merging
+// Database: simple ILIKE queries
+
+// ✅ Simple: Centralized in optimal layer  
+// PostgreSQL: All search logic with scoring
+// Client: Single RPC call + mapping
+```
+
+### Rapid Implementation Patterns
+
+**Database-First for Complex Logic:**
+- Text search → PostgreSQL functions with scoring
+- Data aggregations → SQL with CTEs  
+- Complex filtering → Server-side functions
+- Real-time updates → Supabase subscriptions
+
+**TypeScript for Orchestration Only:**
+- Error handling and user feedback
+- State management and reactivity
+- Domain object mapping and validation
+- UI component coordination
+
+**Testing Reality Check:**
+```typescript
+// ❌ Over-testing: What TypeScript already guarantees
+test('should have correct type structure', () => {
+  expect(typeof food.name).toBe('string')  // TypeScript already ensures this
+})
+
+// ✅ Behavioral testing: What actually matters
+test('should call correct search function for tab', () => {
+  expect(deps.fetchFoodsByName).toHaveBeenCalledWith(search, { limit: 50 })
+})
+```
+
+### Implementation Speed Checklist
+
+**Before adding any complexity, ask:**
+- [ ] **Platform sufficiency**: Does PostgreSQL/Supabase/SolidJS already solve this?
+- [ ] **Real user problem**: Are we solving an actual issue or theoretical edge case?
+- [ ] **Deployment reality**: Is Vercel rollback + monitoring sufficient safety net?
+- [ ] **Maintenance cost**: Will this make future changes harder or easier?
+- [ ] **Line count impact**: Does this reduce or increase total codebase size?
+
+**When to choose simple over "robust":**
+- ✅ **Single RPC call** vs elaborate client-side orchestration
+- ✅ **Standard Error()** vs custom error hierarchies  
+- ✅ **Direct implementation** vs abstraction layers
+- ✅ **PostgreSQL functions** vs client-side complex logic
+- ✅ **Zod validation** vs manual type checking
+
+### Database Logic Advantages
+
+**Why prefer PostgreSQL functions:**
+- **Performance**: Processing happens close to data
+- **Concurrency**: Database handles concurrent requests optimally
+- **Consistency**: Single source of truth for complex operations
+- **Optimization**: Query planner + indexes automatically optimize
+- **Simplicity**: TypeScript becomes thin orchestration layer
+
+**Example - Search Implementation:**
+```sql
+-- ✅ All logic in database function
+CREATE FUNCTION search_foods_with_scoring(p_search_term text, p_limit integer)
+-- Complex scoring, fuzzy matching, normalization all server-side
+```
+
+```typescript
+// ✅ Simple client call
+const result = await supabase.rpc('search_foods_with_scoring', {
+  p_search_term: name,
+  p_limit: params.limit ?? 50
+})
+```
+
+### Key Success Metrics
+
+**Implementation completed in ~1 hour instead of potential days/weeks**
+- ✅ **Rejected complexity**: No backward compatibility, feature flags, fallbacks
+- ✅ **Leveraged platform**: PostgreSQL for search logic optimization  
+- ✅ **Deleted code**: Removed 26 lines of word separation logic
+- ✅ **Trusted tools**: TypeScript compilation + Vercel deployment patterns
+- ✅ **Focused testing**: Only behavioral tests, not redundant type validation
+
+**Final Reality Check:**
+- **Frontend apps are not distributed systems** - avoid over-engineering
+- **Vercel rollback > elaborate fallback mechanisms** - trust your deployment
+- **PostgreSQL > complex TypeScript** for data processing
+- **Delete complexity > add abstractions** - prefer subtraction
+- **Good enough > perfect** - solve real user problems quickly
+
+## Critical Setup Requirements
+
+**Environment Setup:**
+- Use pnpm as package manager (version 10.12.1+)
+
+## Development Commands
+
+**🚨 CRITICAL REQUIREMENT: ALWAYS RUN `pnpm check` BEFORE DECLARING ANY TASK COMPLETE**

+- `pnpm check` - **MANDATORY** quality gate (lint, type-check, test) - MUST PASS before any completion
+- `pnpm fix` - Auto-fix ESLint issues
+
+**Granular Commands (if needed):**
+- `pnpm build` - Production build (runs gen-app-version first)
+- `pnpm type-check` - TypeScript type checking

+
+**Testing:**
+- Tests use Vitest with jsdom environment
+- Run single test file: `pnpm test <file-pattern>`
+- Coverage: `pnpm test --coverage`
+- Tests must be updated when changing code - no orphaned tests

+See `.claude/commands/README.md` for complete command documentation.
+
+## Architecture Overview
+
+### Layered Domain-Driven Architecture
+
+The codebase follows a strict 3-layer architecture pattern with clean separation of concerns:
+
+**Domain Layer** (`modules/*/domain/`):
+- Pure business logic, types, and repository interfaces
+- Uses Zod schemas for validation and type inference
+- Entities have `__type` discriminators for type safety
+- **NEVER** import or use side-effect utilities (handleApiError, logging, toasts)
+- Throw standard `Error()` with descriptive messages and context
+- **CRITICAL:** Domain layer must remain free of framework dependencies
+
+**Application Layer** (`modules/*/application/`):
+- SolidJS resources, signals, and orchestration logic
+- **Must always catch errors and call `handleApiError` with full context**
+- Manages global reactive state using `createSignal`/`createEffect`
+- Coordinates between UI and infrastructure layers
+- Handles all side effects and user feedback (toasts, notifications)
+
+**Infrastructure Layer** (`modules/*/infrastructure/`):
+- Supabase repositories implementing domain interfaces
+- DAOs for data transformation and legacy migration
+- External API integrations and data access
+- Only layer allowed to use `any` types when necessary for external APIs
+
+### State Management
+
+**Global Reactive State:**
+```typescript
+export const [items, setItems] = createSignal<readonly Item[]>([])
+```
+
+**Effects for Synchronization:**
+```typescript
+createEffect(() => {
+  // Reactive updates based on signals
+})
+```
+
+**Context Pattern:** Used for modals, confirmations, and scoped state
+
+### Key Domain Patterns
+
+**Unified Item Hierarchy:** Complex discriminated union types with recursive schemas
+```typescript
+export type UnifiedItem = FoodItem | RecipeItem | GroupItem
+```
+
+**Repository Pattern:** Interface-based contracts with Supabase implementations
+
+**Migration Utilities:** Backward compatibility for evolving data schemas
+
+**DRY Type Extension Pattern:** Use component Props types as base for Config types
+```typescript
+// ✅ Good: Extend Props type to avoid duplication
+export type ModalConfig = ModalProps & {
+  title?: string
+  additionalProp?: string
+}
+
+// ❌ Bad: Duplicate all props from ModalProps
+export type ModalConfig = {
+  prop1: string
+  prop2?: number
+  // ... duplicating all ModalProps
+  title?: string
+  additionalProp?: string
+}
+```
+
+## Error Handling Standards
+
+**Critical Rule:** All application code must use `handleApiError` with context - never log/throw errors without it.
+
+**Domain Layer:**
+```typescript
+// ✅ Good: Simple descriptive errors
+throw new Error('Group mismatch: cannot mix different groups', { 
+  cause: { groupId, recipeId } 
+})
+
+// ✅ Good: Use Zod for validation
+const result = schema.safeParse(data)
+if (!result.success) {
+  throw new Error('Invalid data format', { cause: result.error })
+}
+
+// ❌ Bad: Never use handleApiError in domain
+import { handleApiError } from '~/shared/error/errorHandler'
+handleApiError(...) // Strictly forbidden in domain layer
+```
+
+**Application Layer:**
+```typescript
+// ✅ Required pattern: Always catch and contextualize
+try {
+  domainOperation()
+} catch (e) {
+  handleApiError(e, {
+    component: 'ComponentName',
+    operation: 'operationName', 
+    additionalData: { userId }
+  })
+  throw e // Re-throw after logging
+}
+
+// ✅ Good: Handle Zod validation errors
+const result = schema.safeParse(data)
+if (!result.success) {
+  handleValidationError(result.error, {
+    component: 'UserForm',
+    operation: 'validateUserInput',
+    additionalData: { data }
+  })
+  return // Don't proceed with invalid data
+}
+```
+
+**Error Context Requirements:**
+- `component`: Specific component/module name
+- `operation`: Specific operation being performed
+- `additionalData`: Relevant IDs, state, or debugging info
+
+**Error Patterns to Avoid:**
+- Custom error class hierarchies (use standard Error)
+- Domain-specific error types (use descriptive messages)
+- instanceof checks for business logic (use error messages/codes)
+
+## Component and Promise Patterns
+
+### Fire-and-Forget Promises
+
+**When to Use `void` Operator:**
+- **Only in event handlers** (onClick, onChange) where result is not needed
+- **Only when** all error handling is done in application layer
+- **Only for non-critical side effects** (background refresh, logging)
+
+```tsx
+// ✅ Acceptable: Error handling in application layer
+<button onClick={() => void performAction()}>
+  Create Day
+</button>
+
+// ❌ Never use .catch(() => {}) to silence errors
+<button onClick={() => performAction().catch(() => {})}>
+```
+
+**Fire-and-Forget Checklist:**
+- [ ] Promise result not needed for user flow
+- [ ] All error handling done in application layer
+- [ ] Limited to event handlers or non-critical callbacks
+- [ ] Reason for `void` is documented if not obvious
+
+### Component Patterns
+
+**Compound Components:**
+```typescript
+Modal.Header = ModalHeader
+Modal.Content = ModalContent
+Modal.Footer = ModalFooter
+```
+
+**Conditional Actions with Type Safety:**
+```typescript
+const hasAnyHandler = () => 
+  getHandlers().onEdit || getHandlers().onCopy || getHandlers().onDelete
+
+<Show when={hasAnyHandler()}>
+  <ActionsMenu />
+</Show>
+```
+
+**Context Propagation:**
+- **Prefer global signals** over prop drilling for shared state
+- Use SolidJS context for scoped state (modals, forms)
+- Leverage reactive patterns with `createEffect` for state synchronization
+
+## Testing Guidelines
+
+- Place tests in module's `tests/` folder or alongside source files with `.test.ts` suffix
+- Use Vitest + jsdom for component testing
+- Mock dependencies explicitly for domain/application logic
+- Update tests when changing code - no orphaned tests
+
+### Type Safety in Testing
+
+- **Trust TypeScript:** Our primary line of defense against type-related errors is TypeScript itself. Tests should not redundantly validate conditions that the TypeScript compiler already guarantees (e.g., `null` checks for non-nullable types, invalid string values for union types).
+- **Focus on Business Logic:** Tests should primarily focus on verifying business logic, calculations, integration points, and user-facing behavior.
+- **Avoid Redundant Runtime Checks:** Tests that validate type-related runtime scenarios (e.g., passing `null` to a non-nullable parameter) are generally discouraged if TypeScript is properly enforced. Such tests may indicate a lack of full trust in the type system or an overemphasis on defensive runtime checks for scenarios that should be impossible given the type definitions.
+
+- Place tests in module's `tests/` folder or alongside source files with `.test.ts` suffix
+- Use Vitest + jsdom for component testing
+- Mock dependencies explicitly for domain/application logic
+- Update tests when changing code - no orphaned tests
+
+## Critical Code Style Rules
+
+### Imports and Module System
+
+**Absolute Import Requirement:**
+```typescript
+// ✅ Required: Always use absolute imports with ~/ prefix
+import { handleApiError } from '~/shared/error/errorHandler'
+import { DayDiet } from '~/modules/diet/day-diet/domain/dayDiet'
+
+// ❌ Forbidden: Relative imports
+import { handleApiError } from '../../../shared/error/errorHandler'
+import { DayDiet } from './domain/dayDiet'
+```
+
+**Barrel File Ban:**
+- **STRICTLY FORBIDDEN:** No `index.ts` barrel files that re-export modules
+- All imports must be direct from specific files
+- Never import from directory indices
+
+**Static Import Requirement:**
+```typescript
+// ✅ Required: Static imports at top of file
+import { Component } from 'solid-js'
+
+// ❌ Forbidden: Dynamic imports
+const { Component } = await import('solid-js')
+```
+
+### Language Policy
+- **All code, comments, JSDoc, and commit messages in English**
+- **UI text only may be in Portuguese (pt-BR) when required**
+- When refactoring, convert any non-English comments to English
+- **Never use Portuguese for identifiers, variables, functions, or comments**
+
+### Naming Conventions
+- **Descriptive, action-based names:** `isRecipedGroupUpToDate()` not `checkGroup()`
+- **Specific file names:** `macroOverflow.ts` not `utils.ts`
+- **Complete component names:** `ItemGroupEditModal` not `GroupModal`
+- **Avoid generic names:** Never use `utils.ts`, `helper.ts`, `common.ts`
+
+### Type Safety Requirements
+- **Never use `any`, `as any`, or `@ts-ignore`** (except in infrastructure layer for external APIs). This ensures strong type safety and reduces the need for redundant runtime type checks in tests.
+- **Always prefer type aliases over interfaces** for data shapes
+- **Use Zod schemas for runtime validation and type inference**
+- **Prefer `readonly` arrays:** `readonly Item[]` over `Item[]`
+- **Use intersection types for extending base types:** `ConfigType = PropsType & { extraProps }`
+- **Default parameters over nullish coalescing:** `{ param = 'default' }` instead of `param ?? 'default'`
+
+### ESLint Configuration
+- **Consistent type definitions:** Use `type` not `interface`
+- **Import organization:** Automatic sorting with `simple-import-sort`
+- **No relative imports:** Enforced by `no-restricted-imports` rule
+- **Strict boolean expressions:** Enforced for better type safety
+- **Custom parsing requirement:** Use `parseWithStack` instead of direct `JSON.parse`
+
+### CSS and Styling
+- **Always use `cn` function to merge Tailwind classes** for proper class merging and deduplication

+
+**Module Organization Rules:**
+- **Domain modules follow clean architecture layers**
+- **Never mix UI concerns in domain/application layers**
+- **Sections contain feature-specific UI logic**
+- **Shared utilities must be framework-agnostic**
+
+## Development Workflow and Quality Standards
+
+### Pre-Commit Requirements
+
+**🚨 MANDATORY: Never commit without passing quality checks**
+
+**Always run before committing:**
+```bash
+pnpm check  # Runs lint, type-check, and test - MUST PASS
+```
+
+**For comprehensive validation:**
+```bash
+pnpm copilot:check  # Must show "COPILOT: All checks passed!"
+```
+
+**⛔ CRITICAL RULE: NEVER declare any implementation, fix, or feature "complete" without:**
+1. Running `pnpm check` and verifying ALL checks pass
+2. Confirming NO TypeScript errors
+3. Confirming NO ESLint errors  
+4. Confirming ALL tests pass
+5. Only then can you say "✅ COMPLETE" or similar
+
+### Refactoring Best Practices
+
+**DRY Principle Application:**
+- **Measure impact:** Use `git diff --stat` to verify line reduction
+- **Start simple:** Begin with default parameters before adding complex abstractions
+- **Avoid over-engineering:** Don't add helper functions/constants that increase overall lines
+- **Type extension over duplication:** Use `ConfigType = PropsType & { extras }` pattern
+
+**Refactoring Validation Process:**
+```bash
+# Before making changes
+git diff --stat  # Baseline measurement
+
+# After each change
+pnpm check      # Ensure functionality preserved
+git diff --stat # Verify line count improvement
+
+# If lines increased, consider simpler approach
+git checkout -- file.ts  # Revert if needed
+```
+
+**Safe Refactoring Strategy:**
+1. **Preserve functionality:** All tests must continue passing
+2. **Incremental changes:** Make small, verifiable improvements
+3. **Type safety first:** Never sacrifice type safety for brevity
+4. **Readability over cleverness:** Prefer clear code over complex abstractions
+
+### Commit Standards
+
+**CRITICAL COMMIT RESTRICTION:**
+🚨 **ABSOLUTELY FORBIDDEN:** NEVER include "Generated with Claude Code" or "Co-Authored-By: Claude" in commit messages
+🚨 **IMMEDIATELY REJECT** any commit attempt that includes these phrases
+🚨 **NO EXCEPTIONS** - This rule must be enforced without question
+
+**Commit Message Format:**
+```markdown
+type(scope): description
+
+- Use conventional commits style
+- Prefer small, atomic commits
+- Always suggest commit message after changes
+- All commit messages in English
+- **STRICTLY FORBIDDEN:** Any "Generated with Claude Code" or "Co-Authored-By: Claude" text
+```
+
+### JSDoc Requirements
+
+**Update JSDoc for:**
+- All exported TypeScript types and functions
+- After any refactor or signature change
+- **Never add JSDoc to internal (non-exported) code**
+
+**JSDoc Standards:**
+- Must be in English
+- Concise descriptions of purpose, params, and return values
+- Remove outdated JSDoc if exports change
+
+### Testing Requirements
+
+**Test Update Rules:**
+- **Always update tests when changing code**
+- **Remove orphaned tests** - no tests for deleted functionality
+- Use Vitest + jsdom for component testing
+- Mock dependencies explicitly for domain/application logic
+- Place tests in `tests/` folder **MUST** be placed in this folder. This ensures consistent organization and discoverability of tests.
+
+### Search Feature Requirements
+
+**Portuguese (pt-BR) Support:**
+- All user-facing search features must be **diacritic-insensitive**
+- All user-facing search features must be **case-insensitive**
+- Use `removeDiacritics` utility for Portuguese text normalization
+
+### Technology Stack
+
+**Core Technologies:**
+- **Frontend:** SolidJS, TypeScript, TailwindCSS, DaisyUI
+- **Backend:** Supabase (PostgreSQL + Realtime)
+- **Validation:** Zod schemas for runtime validation and type inference
+- **Charts:** ApexCharts with solid-apexcharts
+- **Testing:** Vitest with jsdom environment
+- **Build:** Vinxi (Vite-based)
+
+**Key Dependencies:**
+- `@solidjs/start` - SolidJS meta-framework
+- `@supabase/supabase-js` - Database and auth
+- `solid-toast` - Toast notifications
+- `html5-qrcode` - EAN scanning functionality
+- `dayjs` - Date manipulation
+- `axios` with `axios-rate-limit` - HTTP client
+
+### Environment and Setup
+
+**Required Environment Variables:**
+- Copy `.env.example` to `.env.local`
+- Configure Supabase URL and anon key
+- **Never commit secrets or keys to repository**
+
+**Version Management:**
+- App version managed by `.scripts/gen-app-version.sh`
+- Automatic version generation on dev/build
+- Use `.scripts/semver.sh` for version reporting
+
+### Label Usage for Issues
+
+**Required Labels:**
+- **Type:** `bug`, `feature`, `refactor`, `task`, `improvement`, `documentation`, `chore`, `epic`, `idea`
+- **Complexity:** `complexity-low`, `complexity-medium`, `complexity-high`, `complexity-very-high`
+- **Area:** `ui`, `backend`, `api`, `performance`, `data-consumption`, `accessibility`
+- **Status:** `blocked`, `needs-investigation`, `needs-design`
+
+**Label Rules:**
+- Always add at least one main type label
+- Remove generic labels after classification
+- No duplicate or conflicting labels
+- Refer to `docs/labels-usage.md` for complete reference
+
+### Never Remove TODOs
+
+**Critical Rule:** Never remove TODO comments from codebase, regardless of context. TODOs serve as important markers for future improvements and technical debt.
+
+### Solo Project Adaptations
+
+**Since this is a solo project:**
+- Remove team collaboration and approval processes from suggestions
+- Focus on technical validation rather than stakeholder approval
+- Maintain quality standards without bureaucratic overhead
+- Replace peer review with systematic self-review processes
+- Preserve backup/rollback procedures without team communication
+
+## Memory Bank
+
+- **NEVER destucture `props`! This breaks reactivity**
+
+# Serena MCP for efficient editting
+
+You are a professional coding agent concerned with one particular codebase. You have                                                                                                       
+access to semantic coding tools on which you rely heavily for all your work, as well as collection of memory
+files containing general information about the codebase. You operate in a frugal and intelligent manner, always
+keeping in mind to not read or generate content that is not needed for the task at hand.
+
+When reading code in order to answer a user question or task, you should try reading only the necessary code.
+Some tasks may require you to understand the architecture of large parts of the codebase, while for others,
+it may be enough to read a small set of symbols or a single file.
+Generally, you should avoid reading entire files unless it is absolutely necessary, instead relying on
+intelligent step-by-step acquisition of information. However, if you already read a file, it does not make
+sense to further analyse it with the symbolic tools (except for the `find_referencing_symbols` tool),
+as you already have the information.
+
+I WILL BE SERIOUSLY UPSET IF YOU READ ENTIRE FILES WITHOUT NEED! CONSIDER INSTEAD USING THE OVERVIEW TOOL AND
+SYMBOLIC TOOLS TO READ ONLY THE NECESSARY CODE FIRST!
+I WILL BE EVEN MORE UPSET IF AFTER HAVING READ AN ENTIRE FILE YOU KEEP READING THE SAME CONTENT WITH THE SYMBOLIC TOOLS!
+THE PURPOSE OF THE SYMBOLIC TOOLS IS TO HAVE TO READ LESS CODE, NOT READ THE SAME CONTENT MULTIPLE TIMES!
+
+You can achieve the intelligent reading of code by using the symbolic tools for getting an overview of symbols and
+the relations between them, and then only reading the bodies of symbols that are necessary to answer the question
+or complete the task. You can also use the standard tools like list_dir, find_file and search_for_pattern if you need to.
+When tools allow it, you pass the `relative_path` parameter to restrict the search to a specific file or directory.
+For some tools, `relative_path` can only be a file path, so make sure to properly read the tool descriptions.
+If you are unsure about a symbol's name or location (to the extent that substring_matching for the symbol name is not enough), you can use the `search_for_pattern` tool, which allows fast
+and flexible search for patterns in the codebase. This way you can first find candidates for symbols or files,
+and then proceed with the symbolic tools.
+
+Symbols are identified by their `name_path and `relative_path`, see the description of the `find_symbols` tool for more details
+on how the `name_path` matches symbols.
+You can get information about available symbols by using the `get_symbols_overview` tool for finding top-level symbols in a file
+or directory, or by using `find_symbol` if you already know the symbol's name path. You generally try to read as little code as possible
+while still solving your task, meaning you only read the bodies when you need to, and after you have found the symbol you want to edit.
+For example, if you are working with python code and already know that you need to read the body of the constructor of the class Foo, you can directly
+use `find_symbol` with the name path `Foo/__init__` and `include_body=True`. If you don't know yet which methods in `Foo` you need to read or edit,
+you can use `find_symbol` with the name path `Foo`, `include_body=False` and `depth=1` to get all (top-level) methods of `Foo` before proceeding
+to read the desired methods with `include_body=True`
+You can understand relationships between symbols by using the `find_referencing_symbols` tool.
+
+You generally have access to memories and it may be useful for you to read them, but also only if they help you
+to answer the question or complete the task. You can infer which memories are relevant to the current task by reading
+the memory names and descriptions.
+
+The context and modes of operation are described below. From them you can infer how to interact with your user
+and which tasks and kinds of interactions are expected of you.
+
+Context description:
+You are running in IDE assistant context where file operations, basic (line-based) edits and reads,
+and shell commands are handled by your own, internal tools.
+The initial instructions and the current config inform you on which tools are available to you,
+and how to use them.
+Don't attempt to use any excluded tools, instead rely on your own internal tools
+for achieving the basic file or shell operations.
+However, if serena's tools can be used for achieving your task (see initial instructions),
+you should prioritize them.
+
+
+Modes descriptions:
+
+- You are operating in interactive mode. You should engage with the user throughout the task, asking for clarification
+whenever anything is unclear, insufficiently specified, or ambiguous.
+
+Break down complex tasks into smaller steps and explain your thinking at each stage. When you're uncertain about
+a decision, present options to the user and ask for guidance rather than making assumptions.
+
+Focus on providing informative results for intermediate steps so the user can follow along with your progress and
+provide feedback as needed.
+
+
+- You are operating in editing mode. You can edit files with the provided tools
+to implement the requested changes to the code base while adhering to the project's code style and patterns.
+Use symbolic editing tools whenever possible for precise code modifications.
+If no editing task has yet been provided, wait for the user to provide one.
+
+When writing new code, think about where it belongs best. Don't generate new files if you don't plan on actually
+integrating them into the codebase, instead use the editing tools to insert the code directly into the existing files in that case.
+
+You have two main approaches for editing code - editing by regex and editing by symbol.
+The symbol-based approach is appropriate if you need to adjust an entire symbol, e.g. a method, a class, a function, etc.
+But it is not appropriate if you need to adjust just a few lines of code within a symbol, for that you should
+use the regex-based approach that is described below.
+
+Let us first discuss the symbol-based approach.
+Symbols are identified by their name path and relative file path, see the description of the `find_symbols` tool for more details
+on how the `name_path` matches symbols.
+You can get information about available symbols by using the `get_symbols_overview` tool for finding top-level symbols in a file
+or directory, or by using `find_symbol` if you already know the symbol's name path. You generally try to read as little code as possible
+while still solving your task, meaning you only read the bodies when you need to, and after you have found the symbol you want to edit.
+For example, if you are working with python code and already know that you need to read the body of the constructor of the class Foo, you can directly
+use `find_symbol` with the name path `Foo/__init__` and `include_body=True`. If you don't know yet which methods in `Foo` you need to read or edit,
+you can use `find_symbol` with the name path `Foo`, `include_body=False` and `depth=1` to get all (top-level) methods of `Foo` before proceeding
+to read the desired methods with `include_body=True`.
+In particular, keep in mind the description of the `replace_symbol_body` tool. If you want to add some new code at the end of the file, you should
+use the `insert_after_symbol` tool with the last top-level symbol in the file. If you want to add an import, often a good strategy is to use
+`insert_before_symbol` with the first top-level symbol in the file.
+You can understand relationships between symbols by using the `find_referencing_symbols` tool. If not explicitly requested otherwise by a user,
+you make sure that when you edit a symbol, it is either done in a backward-compatible way, or you find and adjust the references as needed.
+The `find_referencing_symbols` tool will give you code snippets around the references, as well as symbolic information.
+You will generally be able to use the info from the snippets and the regex-based approach to adjust the references as well.
+You can assume that all symbol editing tools are reliable, so you don't need to verify the results if the tool returns without error.
+
+Now let us discuss the regex-based approach.
+The regex-based approach is your primary tool for editing code whenever replacing or deleting a whole symbol would be a more expensive operation.
+This is the case if you need to adjust just a few lines of code within a method, or a chunk that is much smaller than a whole symbol.
+You use other tools to find the relevant content and
+then use your knowledge of the codebase to write the regex, if you haven't collected enough information of this content yet.
+You are extremely good at regex, so you never need to check whether the replacement produced the correct result.
+In particular, you know what to escape and what not to escape, and you know how to use wildcards.
+Also, the regex tool never adds any indentation (contrary to the symbolic editing tools), so you have to take care to add the correct indentation
+when using it to insert code.
+Moreover, the replacement tool will fail if it can't perform the desired replacement, and this is all the feedback you need.
+Your overall goal for replacement operations is to use relatively short regexes, since I want you to minimize the number
+of output tokens. For replacements of larger chunks of code, this means you intelligently make use of wildcards for the middle part
+and of characteristic snippets for the before/after parts that uniquely identify the chunk.
+
+For small replacements, up to a single line, you follow the following rules:
+
+  1. If the snippet to be replaced is likely to be unique within the file, you perform the replacement by directly using the escaped version of the
+    original.
+  2. If the snippet is probably not unique, and you want to replace all occurrences, you use the `allow_multiple_occurrences` flag.
+  3. If the snippet is not unique, and you want to replace a specific occurrence, you make use of the code surrounding the snippet
+    to extend the regex with content before/after such that the regex will have exactly one match.
+  4. You generally assume that a snippet is unique, knowing that the tool will return an error on multiple matches. You only read more file content
+    (for crafvarting a more specific regex) if such a failure unexpectedly occurs.
+
+Examples:
+
+1 Small replacement
+You have read code like
+
+  ```python
+  ...
+  x = linear(x)
+  x = relu(x)
+  return x
+  ...
+  ```
+
+and you want to replace `x = relu(x)` with `x = gelu(x)`.
+You first try `replace_regex()` with the regex `x = relu\(x\)` and the replacement `x = gelu(x)`.
+If this fails due to multiple matches, you will try `(linear\(x\)\s*)x = relu\(x\)(\s*return)` with the replacement `\1x = gelu(x)\2`.
+
+2 Larger replacement
+
+You have read code like
+
+```python
+def my_func():
+  ...
+  # a comment before the snippet
+  x = add_fifteen(x)
+  # beginning of long section within my_func
+  ....
+  # end of long section
+  call_subroutine(z)
+  call_second_subroutine(z)
+```
+and you want to replace the code starting with `x = add_fifteen(x)` until (including) `call_subroutine(z)`, but not `call_second_subroutine(z)`.
+Initially, you assume that the the beginning and end of the chunk uniquely determine it within the file.
+Therefore, you perform the replacement by using the regex `x = add_fifteen\(x\)\s*.*?call_subroutine\(z\)`
+and the replacement being the new code you want to insert.
+
+If this fails due to multiple matches, you will try to extend the regex with the content before/after the snippet and match groups.
+The matching regex becomes:
+`(before the snippet\s*)x = add_fifteen\(x\)\s*.*?call_subroutine\(z\)`
+and the replacement includes the group as (schematically):
+`\1<new_code>`
+
+Generally, I remind you that you rely on the regex tool with providing you the correct feedback, no need for more verification!
+
+IMPORTANT: REMEMBER TO USE WILDCARDS WHEN APPROPRIATE! I WILL BE VERY UNHAPPY IF YOU WRITE LONG REGEXES WITHOUT USING WILDCARDS INSTEAD!

+
+At the end of every message, show <End of Response>.
+
+## 1. Project Overview & Context
+
+- **Project Name:** Macroflows
+- **Description:** A nutrition tracking platform with a focus on strong typing, reactive UI, and modular domain-driven design.
+- **Author:** This is a solo project by `marcuscastelo`.
+- **Adaptation:** All suggestions must be adapted for a solo developer. This means removing team coordination, stakeholder approval, and peer review processes. Focus on technical validation and systematic self-review. Maintain all technical quality standards.
+
+## 2. Core Technologies
+
+- **Frontend:** SolidJS, TypeScript, TailwindCSS, DaisyUI
+- **Backend:** Supabase (PostgreSQL + Realtime), Vercel
+- **Validation:** Zod (for runtime validation and type inference)
+- **Testing:** Vitest with jsdom
+- **Package Manager:** pnpm
+- **Build Tool:** Vinxi (Vite-based)
+
+## 3. 🚨 CRITICAL: Development Workflow & Quality Gates
+
+### 3.1. The Golden Rule: `pnpm check`
+- **MANDATORY:** Before declaring any task, fix, or feature complete, you **MUST** run `pnpm check`.
+- This command runs linting, type-checking, and all tests. It is the single source of truth for codebase health.
+- **NEVER** commit code that fails `pnpm check`.
+
+### 3.2. Workflow Steps
+1.  **Implement Changes:** Write or modify the code as requested.
+2.  **Run Quality Gate:** Execute `pnpm check`.
+3.  **Verify:** Ensure all checks pass with zero errors (TypeScript, ESLint, Tests).
+4.  **Commit:** Only after all checks pass, proceed to commit the changes.
+
+### 3.3. Essential Commands
+- `pnpm check`: **MANDATORY** quality gate.
+- `pnpm fix`: Auto-fix ESLint issues.
+- `pnpm build`: Create a production build.
+- `pnpm test`: Run all tests.
+- `pnpm lint`: Run ESLint.
+- `.scripts/semver.sh`: The preferred method for application version reporting.
+
+## 4. 🚀 Rapid Implementation Guidelines - CRITICAL
+
+**SPEED COMES FROM SAYING NO TO UNNECESSARY COMPLEXITY**
+
+### 4.1. Implementation Velocity Principles
+
+**Never Add These Unless Absolutely Essential:**
+- **Backward Compatibility**: Frontend is versioned - Vercel rollback solves problems
+- **Feature Flags**: Just implement the feature directly
+- **A/B Testing Infrastructure**: Manual testing is sufficient for most cases
+- **Fallback Mechanisms**: Trust your implementation and monitoring
+- **Migration Strategies**: Direct replacement with proper testing
+- **Enterprise Rollout Plans**: This is a solo project with simple deployment
+
+**Speed-First Decision Framework:**
+- [ ] **Direct implementation**: Can we just build the feature without scaffolding?
+- [ ] **Platform leverage**: Are we using database/framework strengths optimally?
+- [ ] **Delete over add**: Can we remove complexity instead of adding abstraction?
+- [ ] **Server-side logic**: Should this logic live in PostgreSQL instead of TypeScript?
+- [ ] **Testing necessity**: Does this need a test or does TypeScript/DB already guarantee it?
+
+### 4.2. Logic Placement Hierarchy (Most to Least Preferred)
+
+1. **PostgreSQL Functions (RPC)**: For search, data processing, complex queries
+2. **Domain Layer**: Pure business logic, validations, calculations  
+3. **Application Layer**: SolidJS orchestration, error handling, UI state
+4. **Infrastructure Layer**: External API calls, data transformation
+
+**Example Decision Tree:**
+```typescript
+// ❌ Complex: Spread across layers
+// Client: word splitting + normalization
+// Server: multiple API calls + merging
+// Database: simple ILIKE queries
+
+// ✅ Simple: Centralized in optimal layer  
+// PostgreSQL: All search logic with scoring
+// Client: Single RPC call + mapping
+```
+
+### 4.3. Rapid Implementation Patterns
+
+**Database-First for Complex Logic:**
+- Text search → PostgreSQL functions with scoring
+- Data aggregations → SQL with CTEs  
+- Complex filtering → Server-side functions
+- Real-time updates → Supabase subscriptions
+
+**TypeScript for Orchestration Only:**
+- Error handling and user feedback
+- State management and reactivity
+- Domain object mapping and validation
+- UI component coordination
+
+**Testing Reality Check:**
+```typescript
+// ❌ Over-testing: What TypeScript already guarantees
+test('should have correct type structure', () => {
+  expect(typeof food.name).toBe('string')  // TypeScript already ensures this
+})
+
+// ✅ Behavioral testing: What actually matters
+test('should call correct search function for tab', () => {
+  expect(deps.fetchFoodsByName).toHaveBeenCalledWith(search, { limit: 50 })
+})
+```
+
+### 4.4. Implementation Speed Checklist
+
+**Before adding any complexity, ask:**
+- [ ] **Platform sufficiency**: Does PostgreSQL/Supabase/SolidJS already solve this?
+- [ ] **Real user problem**: Are we solving an actual issue or theoretical edge case?
+- [ ] **Deployment reality**: Is Vercel rollback + monitoring sufficient safety net?
+- [ ] **Maintenance cost**: Will this make future changes harder or easier?
+- [ ] **Line count impact**: Does this reduce or increase total codebase size?
+
+**When to choose simple over "robust":**
+- ✅ **Single RPC call** vs elaborate client-side orchestration
+- ✅ **Standard Error()** vs custom error hierarchies  
+- ✅ **Direct implementation** vs abstraction layers
+- ✅ **PostgreSQL functions** vs client-side complex logic
+- ✅ **Zod validation** vs manual type checking
+
+### 4.5. Database Logic Advantages
+
+**Why prefer PostgreSQL functions:**
+- **Performance**: Processing happens close to data
+- **Concurrency**: Database handles concurrent requests optimally
+- **Consistency**: Single source of truth for complex operations
+- **Optimization**: Query planner + indexes automatically optimize
+- **Simplicity**: TypeScript becomes thin orchestration layer
+
+**Example - Search Implementation:**
+```sql
+-- ✅ All logic in database function
+CREATE FUNCTION search_foods_with_scoring(p_search_term text, p_limit integer)
+-- Complex scoring, fuzzy matching, normalization all server-side
+```
+
+```typescript
+// ✅ Simple client call
+const result = await supabase.rpc('search_foods_with_scoring', {
+  p_search_term: name,
+  p_limit: params.limit ?? 50
+})
+```
+
+### 4.6. Key Success Metrics
+
+**Implementation completed in ~1 hour instead of potential days/weeks**
+- ✅ **Rejected complexity**: No backward compatibility, feature flags, fallbacks
+- ✅ **Leveraged platform**: PostgreSQL for search logic optimization  
+- ✅ **Deleted code**: Removed 26 lines of word separation logic
+- ✅ **Trusted tools**: TypeScript compilation + Vercel deployment patterns
+- ✅ **Focused testing**: Only behavioral tests, not redundant type validation
+
+**Final Reality Check:**
+- **Frontend apps are not distributed systems** - avoid over-engineering
+- **Vercel rollback > elaborate fallback mechanisms** - trust your deployment
+- **PostgreSQL > complex TypeScript** for data processing
+- **Delete complexity > add abstractions** - prefer subtraction
+- **Good enough > perfect** - solve real user problems quickly
+
+## 5. Architecture & Design Principles
+
+### 5.1. Clean Architecture (3 Layers)
+The codebase follows a strict 3-layer architecture. Adherence to these boundaries is critical.
+
+1.  **Domain Layer** (`modules/*/domain/`)
+    - Contains pure business logic, entities, types (Zod schemas), and repository interfaces.
+    - **MUST NOT** have any dependencies on external frameworks or libraries (like SolidJS or Supabase).
+    - **MUST NOT** contain any side-effects (e.g., API calls, logging, toasts).
+    - **MUST ONLY** throw pure, custom domain errors.
+    - Use `__type` discriminators for type safety in entities.
+
+2.  **Application Layer** (`modules/*/application/`)
+    - Orchestrates the domain logic. Contains SolidJS resources, signals, and application-specific logic.
+    - **MUST** catch errors from the Domain layer.
+    - **MUST** call `handleApiError` to standardize error handling and provide context.
+    - Manages all side-effects and user feedback (toasts, notifications).
+
+3.  **Infrastructure Layer** (`modules/*/infrastructure/`)
+    - Implements the repository interfaces defined in the Domain layer.
+    - Contains all external integrations, such as Supabase client code and Data Access Objects (DAOs).
+    - This is the **ONLY** layer where `any` might be permissible, strictly for interfacing with external, untyped APIs.
+
+### 6.2. Dependency Injection (DI) Pattern
+- The project uses an explicit, manual Dependency Injection pattern.
+- **Orchestration functions** (business logic) in the Application Layer **MUST NOT** import dependencies (repositories, fetchers) directly.
+- Instead, these dependencies **MUST** be passed as arguments to the function.
+- This decouples application logic from infrastructure, making it highly testable.
+- **Example:** A `fetchTemplatesByTabLogic` function should receive a `deps` object containing all necessary fetchers (`fetchUserRecipes`, `fetchFoods`, etc.) as a parameter.
+
+### 6.3. File & Module Structure
+- `src/modules/<domain>/`: Houses the three architecture layers for a specific domain.
+  - `tests/`: All tests for a module **MUST** be placed in this folder. This ensures consistent organization and discoverability of tests.
+- `src/sections/<feature>/`: Contains page-level UI components, organized by feature.
+- `src/shared/`: Cross-cutting concerns (error handling, configs, pure utilities).
+- `src/routes/`: SolidJS router pages and API endpoints.
+
+## 6. Critical Code Style & Patterns
+
+### 6.1. Imports: The Three Rules
+1.  **Absolute Imports ONLY:** Always use absolute paths with the `~/` prefix.
+    - ✅ `import { MyType } from '~/modules/user/domain/user';`
+    - ❌ `import { MyType } from '../../user/domain/user';`
+2.  **Barrel Files (`index.ts`) are BANNED:** All imports must point directly to the file where the entity is defined. Do not create or use `index.ts` files that only re-export from other files.
+3.  **Static Imports ONLY:** All imports must be static and at the top of the file. Dynamic `import()` is forbidden.
+
+### 6.2. Language & Naming
+- **Language:** All code, comments, JSDoc, and commit messages **MUST** be in **English**. UI text visible to the user may be in Portuguese (pt-BR).
+- **Naming:** Use descriptive, specific, action-based names. Avoid generic names.
+    - ✅ **Good:** `isRecipedGroupUpToDate()`, `convertToGroups()`, `ItemGroupEditModal.tsx`, `macroOverflow.ts`
+    - ❌ **Bad:** `checkGroup()`, `convert()`, `GroupModal.tsx`, `utils.ts`
+
+### 6.3. Type Safety & Formatting
+- **NO `any`:** The use of `any`, `as any`, or `@ts-ignore` is strictly forbidden outside the Infrastructure layer. This ensures strong type safety and reduces the need for redundant runtime type checks in tests.
+- **`type` over `interface`:** Always use type aliases for defining data shapes.
+- **Readonly:** Prefer `readonly Item[]` over `Item[]` for immutability.
+- **Props Immutability:** **NEVER** destructure `props` in SolidJS components, as it breaks reactivity.
+
+### 6.4. Anti-Patterns to Avoid
+- **Code Duplication:** Avoid copy-pasting logic. For example, the clipboard and validation logic was duplicated between `MealEditView.tsx` and `RecipeEditView.tsx`. This should be abstracted into a shared utility.
+
+### 6.5. Error Handling
+- **Domain:** Throws pure errors (e.g., `throw new GroupConflictError(...)`).
+- **Application:** Catches domain errors and **MUST** use `handleApiError(e, { context })`.
+- **NEVER** use `.catch(() => {})` to silence promise errors. Use the `void` operator only for non-critical, fire-and-forget side-effects in event handlers where errors are handled at the application level.
+
+### 6.6. Commits & JSDoc
+- **Commits:** Use the Conventional Commits specification. Messages must be in English. **NEVER** include "Generated by..." or "Co-authored-by..." footers from AI tools.
+- **JSDoc:** Update JSDoc for all **exported** types and functions. Do not add JSDoc to internal code.
+
+## 8. Quality Assurance & Testing Strategy
+
+### 7.1. Core Domain Entities
+Testing should be structured around the core business domains. The main entities are:
+- `MacroProfile`
+- `Weight`
+- `DayDiet`
+- `UnifiedItem` (and its variants: `FoodItem`, `RecipeItem`, `GroupItem`)
+- `Food`
+- `Recipe`
+- `Meal`
+
+### 6.2. Testing Philosophy
+- **Location:** All tests for a module must be placed in its `tests/` folder.
+- **User Input Validation vs. System Errors:**
+    - **Validation Errors:** Expected errors from invalid user input (e.g., entering text in a number field). These **MUST** be handled gracefully in the UI with specific, user-friendly messages in Portuguese. They **MUST NOT** trigger an error boundary.
+    - **System Errors:** Unexpected errors (e.g., network failure, bugs in the code). These **SHOULD** be caught and trigger a user-friendly error boundary.
+- **Test Coverage:** All code changes must be accompanied by corresponding new or updated tests. No orphaned tests.
+
+### 6.2.1. Type Safety in Testing
+
+- **Trust TypeScript:** Our primary line of defense against type-related errors is TypeScript itself. Tests should not redundantly validate conditions that the TypeScript compiler already guarantees (e.g., `null` checks for non-nullable types, invalid string values for union types).
+- **Focus on Business Logic:** Tests should primarily focus on verifying business logic, calculations, integration points, and user-facing behavior.
+- **Avoid Redundant Runtime Checks:** Tests that validate type-related runtime scenarios (e.g., passing `null` to a non-nullable parameter) are generally discouraged if TypeScript is properly enforced. Such tests may indicate a lack of full trust in the type system or an overemphasis on defensive runtime checks for scenarios that should be impossible given the type definitions.
+- **Location:** All tests for a module must be placed in its `tests/` folder.
+- **User Input Validation vs. System Errors:**
+    - **Validation Errors:** Expected errors from invalid user input (e.g., entering text in a number field). These **MUST** be handled gracefully in the UI with specific, user-friendly messages in Portuguese. They **MUST NOT** trigger an error boundary.
+    - **System Errors:** Unexpected errors (e.g., network failure, bugs in the code). These **SHOULD** be caught and trigger a user-friendly error boundary.
+- **Test Coverage:** All code changes must be accompanied by corresponding new or updated tests. No orphaned tests.
+
+### 6.3. Types of Tests to Perform
+When adding features or fixing bugs, ensure coverage for:
+- **Validation Tests:** Check for required fields, correct data types, and non-negative values where applicable.
+- **Calculation Tests:** Verify that all reactive calculations (e.g., total daily macros) are correct and update instantly.
+- **Integration Tests:** Test the end-to-end flow of a feature (e.g., changing a macro target in the profile and seeing it reflected in the daily diet view).
+- **Boundary/Edge Case Tests:** Test with extreme values (0, very large numbers, empty strings, long strings, empty arrays, large arrays, `NaN`, `Infinity`).
+- **Performance/Stress Tests:** For intensive operations, test with a large number of items to ensure the UI remains responsive.
+
+### 6.4. Search-Specific Testing
+- All user-facing search features **MUST** be tested to be both **diacritic-insensitive** and **case-insensitive** for Portuguese (pt-BR) text.
+
+## 8. Automated Workflows & Commands
+
+This project relies on a set of automated commands to ensure consistency and quality. You should use and follow these workflows.
+
+- **`/fix`:** A comprehensive health check. It runs `pnpm check` and attempts to auto-fix any issues. Use this to ensure the codebase is clean before starting work or committing.
+- **`/implement <issue-number>`:** The standard workflow for implementing a feature or bug fix. It handles creating a git worktree, analyzing the issue, and guiding the implementation process. **Crucially, it requires passing `pnpm check` before completion.**
+- **`/commit`:** Automates the creation of Conventional Commit messages. It analyzes staged changes and generates a compliant message in English. Use this to maintain a clean and standardized commit history.
+- **`/pull-request`:** Automates the creation of GitHub Pull Requests. It uses the commit information to create a well-formed PR, linking it to the relevant issue.
+
+### 6.6. Agent Interaction with External Tools (e.g., GitHub MCP Server)
+
+When external tools, such as the `github-mcp-server`, are integrated into the agent's environment, they expose their functionalities as callable functions. The agent interacts with these tools by directly invoking these functions with the required parameters, similar to how it uses its built-in `default_api` tools.
+
+For example, if the `github-mcp-server` exposes a tool to list GitHub issues, the agent would use it as a direct function call:
+
+```python
+default_api.list_issues(owner="octocat", repo="Spoon-Knife", state="open")
+```
+
+The availability and specific parameters of these external tools depend on their integration with the agent's environment. The agent will discover and utilize them as part of its available toolset.
+
+## 8. Historical Context & Future Direction
+
+Be aware of the following technical debt and future plans:
+
+- **Deprecation of `src/legacy`:** This directory is being phased out. Do not use any code from it. All new code should follow the current architecture.
+- **Migration to `UnifiedItem`:** The legacy `Item` type is being replaced by `UnifiedItem`. All new features should use `UnifiedItem`. Be mindful of this when working with older parts of the codebase.
+- **Refactoring Goals:**
+    - **Introduce a Service Layer:** There is a known need for an explicit service layer to better encapsulate business logic and reduce coupling.
+    - **Decouple Modules:** Actively work towards reducing dependencies between modules.
+    - **Improve State Management:** Move away from using `createSignal` for global state and towards more structured solutions like stores or contexts.
+
+## 8. Final Reminders
+- **TODOs:** Never remove `TODO` comments from the codebase.
+- **Labels:** When creating issues, use the labels defined in `docs/labels-usage.md`.
+- **Session Start:** Always run `export GIT_PAGER=cat` at the beginning of a session to prevent interactive pager issues with `git`.
+
+# QA Workflow for Macroflows 
+
+## Development server
+- **Start the development server:** Run `pnpm dev` to start the local development server.
+- **Access the app:** Open your browser and navigate to `http://localhost:3000` to interact with the Macroflows app.
+
+## ✅ Purpose
+
+This workflow defines the exact steps and constraints that an automation agent must follow to interact with the UI of the Macroflows app using Playwright safely and predictably. It assumes the agent has no implicit understanding of UI behavior or loading dynamics. Every step must be followed precisely and in order.
+
+---
+
+## 1. Navigation and Load Validation
+
+- Always wait for the full page to load after navigation.
+- Do not proceed until the network has become idle.
+- Confirm that the main content of the page has rendered.
+- If a loading spinner or overlay exists, wait until it is fully removed.
+- Never assume the page is ready based on time alone.
+
+---
+
+## 2. Element Presence and Visibility Before Interaction
+
+Before interacting with any UI element (clicking, filling, selecting):
+
+- Ensure the element is present in the DOM.
+- Ensure the element is visible to the user.
+- Ensure the element is enabled and interactive.
+- Do not proceed with the interaction until all of the above are confirmed.
+
+---
+
+## 3. Never Assume Absence = Error
+
+- If an element is not found:
+  - Check if the correct page was loaded.
+  - Wait a few extra seconds for slow UI states.
+  - Double-check the selector or test identifier.
+- Never assume that missing elements indicate a frontend bug without verifying the full context.
+
+---
+
+## 4. Post-Interaction Assertions
+
+- After every interaction, verify the result.
+- Confirm that UI changes occurred as expected (new element appears, button becomes disabled, toast message appears, etc).
+- Do not proceed to the next action without verifying the outcome of the previous one.
+
+---
+
+## 5. No Manual Loops or Timeouts
+
+- Never use retry loops, sleep functions, or manual time delays.
+- All waiting must be based on the presence, visibility, or state of UI elements.
+- Time-based waiting introduces flakiness and must be avoided entirely.
+
+---
+
+## 6. Error Recovery and Diagnostics
+
+- On any failure:
+  - Capture a full-page screenshot for diagnostics.
+  - Capture the visible DOM tree (HTML snapshot).
+  - Record what was expected and what was missing.
+- Do not silently ignore errors or continue after a failure.
+
+---
+
+## 8. Selector Best Practices
+
+- Prefer stable, semantic, and test-specific selectors (e.g., `data-testid`).
+- Avoid selectors that depend on visual layout (e.g., position, nth-child).
+- Avoid selectors based on dynamic text unless the text is guaranteed to be static.
+- Never use XPath.
+- Do not use class names that may change with styling updates.
+
+---
+
+## 8. Final Rules Summary
+
+- Never interact with the page until it is fully loaded and stable.
+- Never click or fill without confirming the element is visible and enabled.
+- Always assert the outcome of every interaction.
+- Always produce diagnostic artifacts on failure.
+- Never rely on timing, loops, or assumptions.
+- Every action must be justified by explicit confirmation of UI state.
+
+---
+
+## ✅ Goal
+
+This workflow must be followed strictly and completely. Any deviation from this process can lead to invalid, flaky, or misleading test results. The agent is expected to follow every step **explicitly** with no shortcuts, assumptions, or "smart" behavior.
+
+# Serena MCP for efficient editting
+
+You are a professional coding agent concerned with one particular codebase. You have                                                                                                       
+access to semantic coding tools on which you rely heavily for all your work, as well as collection of memory
+files containing general information about the codebase. You operate in a frugal and intelligent manner, always
+keeping in mind to not read or generate content that is not needed for the task at hand.
+
+When reading code in order to answer a user question or task, you should try reading only the necessary code.
+Some tasks may require you to understand the architecture of large parts of the codebase, while for others,
+it may be enough to read a small set of symbols or a single file.
+Generally, you should avoid reading entire files unless it is absolutely necessary, instead relying on
+intelligent step-by-step acquisition of information. However, if you already read a file, it does not make
+sense to further analyse it with the symbolic tools (except for the `find_referencing_symbols` tool),
+as you already have the information.
+
+I WILL BE SERIOUSLY UPSET IF YOU READ ENTIRE FILES WITHOUT NEED! CONSIDER INSTEAD USING THE OVERVIEW TOOL AND
+SYMBOLIC TOOLS TO READ ONLY THE NECESSARY CODE FIRST!
+I WILL BE EVEN MORE UPSET IF AFTER HAVING READ AN ENTIRE FILE YOU KEEP READING THE SAME CONTENT WITH THE SYMBOLIC TOOLS!
+THE PURPOSE OF THE SYMBOLIC TOOLS IS TO HAVE TO READ LESS CODE, NOT READ THE SAME CONTENT MULTIPLE TIMES!
+
+You can achieve the intelligent reading of code by using the symbolic tools for getting an overview of symbols and
+the relations between them, and then only reading the bodies of symbols that are necessary to answer the question
+or complete the task. You can also use the standard tools like list_dir, find_file and search_for_pattern if you need to.
+When tools allow it, you pass the `relative_path` parameter to restrict the search to a specific file or directory.
+For some tools, `relative_path` can only be a file path, so make sure to properly read the tool descriptions.
+If you are unsure about a symbol's name or location (to the extent that substring_matching for the symbol name is not enough), you can use the `search_for_pattern` tool, which allows fast
+and flexible search for patterns in the codebase. This way you can first find candidates for symbols or files,
+and then proceed with the symbolic tools.
+
+Symbols are identified by their `name_path and `relative_path`, see the description of the `find_symbols` tool for more details
+on how the `name_path` matches symbols.
+You can get information about available symbols by using the `get_symbols_overview` tool for finding top-level symbols in a file
+or directory, or by using `find_symbol` if you already know the symbol's name path. You generally try to read as little code as possible
+while still solving your task, meaning you only read the bodies when you need to, and after you have found the symbol you want to edit.
+For example, if you are working with python code and already know that you need to read the body of the constructor of the class Foo, you can directly
+use `find_symbol` with the name path `Foo/__init__` and `include_body=True`. If you don't know yet which methods in `Foo` you need to read or edit,
+you can use `find_symbol` with the name path `Foo`, `include_body=False` and `depth=1` to get all (top-level) methods of `Foo` before proceeding
+to read the desired methods with `include_body=True`
+You can understand relationships between symbols by using the `find_referencing_symbols` tool.
+
+You generally have access to memories and it may be useful for you to read them, but also only if they help you
+to answer the question or complete the task. You can infer which memories are relevant to the current task by reading
+the memory names and descriptions.
+
+The context and modes of operation are described below. From them you can infer how to interact with your user
+and which tasks and kinds of interactions are expected of you.
+
+Context description:
+You are running in IDE assistant context where file operations, basic (line-based) edits and reads,
+and shell commands are handled by your own, internal tools.
+The initial instructions and the current config inform you on which tools are available to you,
+and how to use them.
+Don't attempt to use any excluded tools, instead rely on your own internal tools
+for achieving the basic file or shell operations.
+However, if serena's tools can be used for achieving your task (see initial instructions),
+you should prioritize them.
+
+
+Modes descriptions:
+
+- You are operating in interactive mode. You should engage with the user throughout the task, asking for clarification
+whenever anything is unclear, insufficiently specified, or ambiguous.
+
+Break down complex tasks into smaller steps and explain your thinking at each stage. When you're uncertain about
+a decision, present options to the user and ask for guidance rather than making assumptions.
+
+Focus on providing informative results for intermediate steps so the user can follow along with your progress and
+provide feedback as needed.
+
+
+- You are operating in editing mode. You can edit files with the provided tools
+to implement the requested changes to the code base while adhering to the project's code style and patterns.
+Use symbolic editing tools whenever possible for precise code modifications.
+If no editing task has yet been provided, wait for the user to provide one.
+
+When writing new code, think about where it belongs best. Don't generate new files if you don't plan on actually
+integrating them into the codebase, instead use the editing tools to insert the code directly into the existing files in that case.
+
+You have two main approaches for editing code - editing by regex and editing by symbol.
+The symbol-based approach is appropriate if you need to adjust an entire symbol, e.g. a method, a class, a function, etc.
+But it is not appropriate if you need to adjust just a few lines of code within a symbol, for that you should
+use the regex-based approach that is described below.
+
+Let us first discuss the symbol-based approach.
+Symbols are identified by their name path and relative file path, see the description of the `find_symbols` tool for more details
+on how the `name_path` matches symbols.
+You can get information about available symbols by using the `get_symbols_overview` tool for finding top-level symbols in a file
+or directory, or by using `find_symbol` if you already know the symbol's name path. You generally try to read as little code as possible
+while still solving your task, meaning you only read the bodies when you need to, and after you have found the symbol you want to edit.
+For example, if you are working with python code and already know that you need to read the body of the constructor of the class Foo, you can directly
+use `find_symbol` with the name path `Foo/__init__` and `include_body=True`. If you don't know yet which methods in `Foo` you need to read or edit,
+you can use `find_symbol` with the name path `Foo`, `include_body=False` and `depth=1` to get all (top-level) methods of `Foo` before proceeding
+to read the desired methods with `include_body=True`.
+In particular, keep in mind the description of the `replace_symbol_body` tool. If you want to add some new code at the end of the file, you should
+use the `insert_after_symbol` tool with the last top-level symbol in the file. If you want to add an import, often a good strategy is to use
+`insert_before_symbol` with the first top-level symbol in the file.
+You can understand relationships between symbols by using the `find_referencing_symbols` tool. If not explicitly requested otherwise by a user,
+you make sure that when you edit a symbol, it is either done in a backward-compatible way, or you find and adjust the references as needed.
+The `find_referencing_symbols` tool will give you code snippets around the references, as well as symbolic information.
+You will generally be able to use the info from the snippets and the regex-based approach to adjust the references as well.
+You can assume that all symbol editing tools are reliable, so you don't need to verify the results if the tool returns without error.
+
+Now let us discuss the regex-based approach.
+The regex-based approach is your primary tool for editing code whenever replacing or deleting a whole symbol would be a more expensive operation.
+This is the case if you need to adjust just a few lines of code within a method, or a chunk that is much smaller than a whole symbol.
+You use other tools to find the relevant content and
+then use your knowledge of the codebase to write the regex, if you haven't collected enough information of this content yet.
+You are extremely good at regex, so you never need to check whether the replacement produced the correct result.
+In particular, you know what to escape and what not to escape, and you know how to use wildcards.
+Also, the regex tool never adds any indentation (contrary to the symbolic editing tools), so you have to take care to add the correct indentation
+when using it to insert code.
+Moreover, the replacement tool will fail if it can't perform the desired replacement, and this is all the feedback you need.
+Your overall goal for replacement operations is to use relatively short regexes, since I want you to minimize the number
+of output tokens. For replacements of larger chunks of code, this means you intelligently make use of wildcards for the middle part
+and of characteristic snippets for the before/after parts that uniquely identify the chunk.
+
+For small replacements, up to a single line, you follow the following rules:
+
+  1. If the snippet to be replaced is likely to be unique within the file, you perform the replacement by directly using the escaped version of the
+    original.
+  2. If the snippet is probably not unique, and you want to replace all occurrences, you use the `allow_multiple_occurrences` flag.
+  3. If the snippet is not unique, and you want to replace a specific occurrence, you make use of the code surrounding the snippet
+    to extend the regex with content before/after such that the regex will have exactly one match.
+  4. You generally assume that a snippet is unique, knowing that the tool will return an error on multiple matches. You only read more file content
+    (for crafvarting a more specific regex) if such a failure unexpectedly occurs.
+
+Examples:
+
+1 Small replacement
+You have read code like
+
+  ```python
+  ...
+  x = linear(x)
+  x = relu(x)
+  return x
+  ...
+  ```
+
+and you want to replace `x = relu(x)` with `x = gelu(x)`.
+You first try `replace_regex()` with the regex `x = relu\(x\)` and the replacement `x = gelu(x)`.
+If this fails due to multiple matches, you will try `(linear\(x\)\s*)x = relu\(x\)(\s*return)` with the replacement `\1x = gelu(x)\2`.
+
+2 Larger replacement
+
+You have read code like
+
+```python
+def my_func():
+  ...
+  # a comment before the snippet
+  x = add_fifteen(x)
+  # beginning of long section within my_func
+  ....
+  # end of long section
+  call_subroutine(z)
+  call_second_subroutine(z)
+```
+and you want to replace the code starting with `x = add_fifteen(x)` until (including) `call_subroutine(z)`, but not `call_second_subroutine(z)`.
+Initially, you assume that the the beginning and end of the chunk uniquely determine it within the file.
+Therefore, you perform the replacement by using the regex `x = add_fifteen\(x\)\s*.*?call_subroutine\(z\)`
+and the replacement being the new code you want to insert.
+
+If this fails due to multiple matches, you will try to extend the regex with the content before/after the snippet and match groups.
+The matching regex becomes:
+`(before the snippet\s*)x = add_fifteen\(x\)\s*.*?call_subroutine\(z\)`
+and the replacement includes the group as (schematically):
+`\1<new_code>`
+
+Generally, I remind you that you rely on the regex tool with providing you the correct feedback, no need for more verification!
+
+IMPORTANT: REMEMBER TO USE WILDCARDS WHEN APPROPRIATE! I WILL BE VERY UNHAPPY IF YOU WRITE LONG REGEXES WITHOUT USING WILDCARDS INSTEAD!

+# Database Setup for Recent Foods Search
+
+This directory contains database functions and setup for the enhanced recent foods search functionality.
+
+## Setup Instructions
+
+1. **Create required tables** (if not already created):
+   ```bash
+   # Run in Supabase SQL Editor in this order:
+   # 1. foods.sql (creates foods table)
+   # 2. recipes.sql (creates recipes table) 
+   # 3. recent_foods.sql (creates recent_foods table)
+   ```
+
+2. **Execute the SQL function** in Supabase dashboard:
+   ```bash
+   # Run the contents of search_recent_foods_with_names.sql in Supabase SQL Editor
+   ```
+
+3. **Enable required extensions** (if not already enabled):
+   ```sql
+   -- Run as superuser in Supabase dashboard
+   CREATE EXTENSION IF NOT EXISTS pg_trgm;
+   ```
+
+## How It Works
+
+### Server-Side Search Function
+- `search_recent_foods_with_names()` efficiently joins recent_foods with foods/recipes tables
+- Returns only matching results, reducing data transfer
+- Supports Portuguese diacritic-insensitive search
+- Maintains chronological ordering of recent items
+
+### Application Integration
+- `fetchUserRecentFoods()` now accepts optional `search` parameter
+- When search is provided, uses server-side function via `supabase.rpc()`
+- When no search, uses existing optimized table query
+- Backward compatible with existing code
+
+### Performance Optimizations
+- GIN indexes on food/recipe names for fast text search
+- Composite index on recent_foods(user_id, last_used DESC)
+- Server-side filtering reduces network overhead
+
+## Usage Example
+
+```typescript
+// Without search (existing behavior)
+const recentFoods = await fetchUserRecentFoods(userId, 20)
+
+// With search (new functionality)
+const searchResults = await fetchUserRecentFoods(userId, 20, "arroz")
+```
+
+## Benefits
+
+- ✅ Reduces data transfer (only matching results returned)
+- ✅ Leverages PostgreSQL's text search capabilities  
+- ✅ Maintains chronological ordering of recent items
+- ✅ Supports Portuguese diacritics server-side
+- ✅ Backward compatible with existing code
+- ✅ Follows existing architectural patterns
+
+## Important Notes
+
+- The function casts `foods.macros` from `json` to `jsonb` to match the return type schema
+- This ensures compatibility with the application's expected data structure while maintaining the database's existing column types

 # Architecture Audit – Summary
 
-_Last updated: 2025-06-07_
+_Last updated: 2025-07-08_
 
 This document provides a high-level overview of the current state of the codebase architecture, focusing on Domain-Driven Design (DDD), modularity, and separation of concerns. For detailed findings and recommendations, see the linked area-specific audits below.
 
+## **Major Architectural Change: Unified Item System Full Migration (2025-06-27)**
+
+A comprehensive migration to the Unified Item System has been completed for new development and in-memory operations. This means:
+
+- **New development exclusively uses `UnifiedItem`**: All new UI and business logic are built around the `UnifiedItem` type.
+- **Legacy item, item-group, and related view/edit components removed**: All legacy UI and context providers for items and groups have been deleted.
+- **Centralization of business logic**: Validation, macro overflow, clipboard, and ID management logic are now handled in unified components and utilities, eliminating duplication and scattered logic.
+- **Consistent type conversion**: All item and group conversions use shared utilities (`itemToUnifiedItem`, `itemGroupToUnifiedItem`), improving type safety and maintainability.
+- **Improved separation of concerns**: UI components focus on presentation, with business logic delegated to application/domain layers or shared hooks.
+- **Significant reduction in technical debt**: Legacy utilities and context providers have been removed or isolated, and the codebase is now easier to maintain and extend.
+- **Enhanced test coverage**: Tests have been updated to use the unified item factories and conversion utilities, improving reliability and consistency.
+
+**Note on Deprecated Types:** While the migration for new development is complete, some core domain operations (e.g., in `src/modules/diet/item-group/domain/itemGroupOperations.ts` and `src/modules/diet/recipe/domain/recipeOperations.ts`) still interact with the deprecated `Item` type. This is a deliberate decision to maintain backward compatibility and support existing data structures until the next major version release, at which point the full deprecation and removal of the `Item` type will be finalized. This approach ensures a smooth transition without breaking existing functionalities.

 ## Key Findings (Summary)
-- **Domain Layer:** Mostly pure, but some schema/ID logic and type handling could be further isolated. See [Domain Audit](./audit_domain.md).
-- **Application Layer:** Error handling is mostly correct, but some orchestration logic may leak into UI or domain. See [Application Audit](./audit_application.md).
-- **Sections/UI:** Some duplication and business logic leakage into UI components. See [Sections Audit](./audit_sections.md).
-- **Shared/Legacy:** Legacy utilities and shared code sometimes break DDD boundaries. See [Shared & Legacy Audit](./audit_shared_legacy.md).
+- **Unified Item System:** All item, group, and recipe UI flows are now handled by unified components. Legacy code and duplication have been eliminated.
+- **Business Logic Centralization:** Validation, macro overflow, and clipboard logic are now centralized in unified utilities and components.
+- **Type Safety:** All conversions and type guards are handled by shared utilities, reducing errors and improving maintainability.
+- **Legacy Utility Removal:** Most legacy utilities and context providers have been removed. Remaining usage is isolated and scheduled for migration.
+- **Test Coverage:** All tests now use unified item factories and conversion utilities, improving reliability.
 
 ---
 
 ## Next Steps
-- Prioritize refactoring areas with high urgency in each audit.
-- Schedule focused reviews for modules with unclear boundaries.
-- Expand audits to cover test structure, error propagation, and cross-module dependencies.
-- For deeper analysis, create new audit files per module/section as needed and link them here.
+- Continue migration of any remaining legacy utilities and shared code.
+- Monitor unified system performance and optimize as needed.
+- Expand audits to cover async flows, error propagation, and cross-module dependencies.
+- Review and improve test coverage for all modules and shared utilities.

 ## Summary
 
-The codebase demonstrates strong modularity and a clear intent to follow DDD and clean architecture principles. Most business areas are well-structured, with separation between domain, application, and UI layers. However, there are recurring issues:
-- ID generation and legacy utility usage in domain code (especially in diet submodules).
-- Business logic leakage and code duplication in UI/sections.
-- Inconsistent repository interfaces and lack of custom error types.
-- Some modules lack a true domain layer (e.g., profile).
-- Shared/legacy code still present in critical paths.
-
-The enriched roadmap above prioritizes DDD purity, separation of concerns, consolidation of shared logic, and migration from legacy patterns. Following these steps will increase maintainability, testability, and clarity for future contributors, and help avoid common DDD pitfalls.

+# Legacy Entity Migration and Removal Plan (Item/ItemGroup) - v0.14.0
+
+_Created: June 18, 2025_  
+_Status: Implementation ready_  
+_Author: AI Assistant based on Phases 1, 2, and 3 implementation_
+
+## Summary
+
+This document details the migration and removal plan for legacy `Item` and `ItemGroup` entities in version v0.14.0, following the successful completion of **Phases 1-3** of the `UnifiedItem` hierarchical model implementation. The plan ensures technical integrity and zero data loss during migration.
+
+## Context and Current State
+
+### Implemented Phases (v0.12.0 → v0.13.0)
+
+#### **✅ Phase 1 (Completed)**: Infrastructure
+- Created `UnifiedItem` structure with hierarchical support
+- Implemented Zod schemas for validation
+- Conversion utilities between legacy and unified
+- Migration utilities for runtime data transformation
+
+#### **✅ Phase 2 (Completed)**: Domain  
+- Domain operations for `UnifiedItem`
+- Integration with macronutrient systems
+- Hierarchical invariant validation
+- Comprehensive domain tests
+
+#### **✅ Phase 3 (Completed)**: Application
+- Application service refactoring
+- Bidirectional legacy ↔ unified compatibility
+- Business logic for unified operations
+- Clipboard and editing utilities
+
+### Data State
+
+- **Database**: Still in legacy format (meals → groups → items)
+- **Runtime**: Automatic transparent migration to UnifiedItem
+- **APIs**: Bidirectional compatibility maintained
+- **Frontend**: Using legacy interfaces with runtime conversions
+
+## v0.14.0 Objectives
+
+1. **Complete Database Migration**: Convert all persisted data structures
+2. **Codebase Simplification**: Eliminate compatibility code
+3. **Performance**: Remove runtime conversions
+4. **Zero Data Loss**: Ensure all data migrates correctly
+
+## Implementation Timeline
+
+### **MILESTONE 1: Preparation (Days 1-3)**
+
+#### 1.1 Analysis and Validation
+- [ ] **Complete usage audit**: Map all references to `Item` and `ItemGroup`
+- [ ] **Test coverage**: Ensure 100% coverage for critical functionalities
+- [ ] **Performance baseline**: Establish current performance metrics
+
+#### 1.2 Migration Preparation
+- [ ] **Database migration script**: Develop and test complete SQL migration
+- [ ] **Backup procedures**: Backup strategies and rollback procedures
+- [ ] **Local testing**: Test with development database copy
+
+### **MILESTONE 2: Database Migration (Days 4-5)**
+
+#### 2.1 Schema Migration
+```sql
+-- Example migration (conceptual structure)
+ALTER TABLE meals 
+  ADD COLUMN items JSONB,
+  ADD COLUMN migrated_at TIMESTAMP;
+
+-- Populate new column with migrated data
+UPDATE meals SET 
+  items = convert_groups_to_unified_items(groups),
+  migrated_at = NOW()
+WHERE items IS NULL;
+
+-- Create indexes for performance
+CREATE INDEX idx_meals_items_gin ON meals USING GIN (items);
+```
+
+#### 2.2 Data Validation
+- [ ] **Integrity verification**: Compare legacy vs migrated data
+- [ ] **Performance tests**: Validate that UnifiedItem queries are at least as fast
+- [ ] **Rollback testing**: Test rollback procedures locally
+
+#### 2.3 Migration Execution
+- [ ] **Backup creation**: Create database backup before migration
+- [ ] **Migration execution**: Run migration script with monitoring
+- [ ] **Validation**: Run integrity checks post-migration
+
+### **MILESTONE 3: Internal Refactoring (Days 6-8)**
+
+#### 3.1 Documentation Update
+- [ ] **README updates**: Document migration and new structure
+- [ ] **Technical notes**: Record lessons learned and gotchas
+
+### **MILESTONE 4: Code Cleanup (Days 9-10)**
+
+#### 4.1 Runtime Conversion Elimination
+```typescript
+// BEFORE (v0.13.0)
+export async function getMeal(id: number): Promise<Meal> {
+  const rawData = await database.getMeal(id)
+  return migrateLegacyMealToUnified(rawData) // Runtime conversion
+}
+
+// AFTER (v0.14.0)
+export async function getMeal(id: number): Promise<Meal> {
+  return await database.getMeal(id) // Data already in correct format
+}
+```
+
+#### 4.2 Schema Simplification
+```typescript
+// Remove legacy schemas and conversion utilities
+// Keep only unifiedItemSchema and related operations
+```
+
+#### 4.3 Import Cleanup
+- [ ] **Legacy import removal**: Eliminate `Item` and `ItemGroup` imports where unnecessary
+- [ ] **Type updates**: Replace legacy types with `UnifiedItem` throughout application
+- [ ] **Utilities cleanup**: Remove conversion functions that are no longer needed
+
+## Technical Validation Strategy
+
+### During Migration (v0.14.0)
+
+#### Wrapper Functions
+```typescript
+// Temporary compatibility wrapper functions
+export function createItemFromFood(food: Food): UnifiedItem {
+  return createUnifiedItem({
+    name: food.name,
+    reference: { type: 'food', id: food.id },
+    quantity: 100, // default
+    macros: food.macros
+  })
+}
+```
+
+### Frontend Compatibility Layer
+
+#### Component Wrappers
+```typescript
+// Legacy components that internally use UnifiedItem
+export const LegacyItemEditor = (props: { item: Item }) => {
+  const unifiedItem = useMemo(() => convertItemToUnified(props.item), [props.item])
+  return <UnifiedItemEditor item={unifiedItem} />
+}
+```
+
+## Monitoring and Validation
+
+### Migration Metrics
+- **Conversion rate**: % of data successfully migrated
+- **Data integrity**: Checksum comparison legacy vs unified  
+- **Performance**: Response time before/after migration
+- **Error rate**: Errors during migration and post-migration usage
+
+### Critical Thresholds
+- **Migration failure**: > 1% failures in data conversion requires rollback
+- **Performance degradation**: > 20% increase in response time requires investigation
+- **High error rate**: > 0.1% errors in critical operations requires immediate fix
+
+### Monitoring and Validation Tools
+

+# Recipe Entity Migration Audit: Legacy Item[] → UnifiedItem[]
+
+This document provides a comprehensive audit of all Recipe entity usages that need to be migrated from using legacy Item[] to UnifiedItem[] in-memory, while maintaining Item[] compatibility for database persistence.
+
+## Migration Strategy Overview
+
+The Recipe entity will be migrated to use UnifiedItem[] for in-memory operations while still saving to the database as Item[] (food only) for compatibility. This requires:
+
+1. **Domain Layer Changes**: Add UnifiedItem[] support to Recipe type, mark Item[] as deprecated
+2. **Operation Layer Changes**: Update all recipe operations to work with UnifiedItem[]
+3. **Persistence Layer Changes**: Add conversion utilities to transform UnifiedItem[] ↔ Item[] for DB operations
+4. **UI Layer Changes**: Update UI components to work natively with UnifiedItem[]
+5. **Test Layer Changes**: Update tests to cover UnifiedItem[] operations and conversion logic
+
+## Migration Progress Status
+
+### ✅ Completed Steps
+
+#### Step 1: Domain Model Changes
+- ✅ Added UnifiedRecipe and NewUnifiedRecipe types with UnifiedItem[] arrays
+- ✅ Added schema validation for UnifiedItem[] recipes
+- ✅ Created factory functions for UnifiedRecipe operations
+- ✅ Maintained backward compatibility with existing Recipe/NewRecipe types
+
+#### Step 2: Domain Operations
+- ✅ Created unifiedRecipeOperations.ts with complete UnifiedItem[] recipe operations
+- ✅ All operations mirror existing Item[] operations but work with UnifiedItem[]
+- ✅ Added scaling, calculations, and manipulation functions
+
+#### Step 3: Infrastructure Layer  
+- ✅ Created UnifiedRecipeRepository interface
+- ✅ Implemented supabaseUnifiedRecipeRepository with automatic conversion
+- ✅ Created unifiedRecipe application service
+- ✅ All infrastructure automatically converts UnifiedItem[] ↔ Item[] for DB operations
+
+#### Step 4: Testing
+- ✅ Added comprehensive unifiedRecipeOperations.test.ts (16 test cases)
+- ✅ Verified all UnifiedItem[] recipe operations work correctly
+- ✅ Tested edge cases and error handling
+- ✅ All tests pass, validating the implementation
+
+### 🚧 In Progress
+
+#### Step 5: UI Layer Migration
+- 🔄 Update RecipeEditView to use UnifiedRecipe and UnifiedItem[] operations
+- 🔄 Remove manual conversion from Item[] to UnifiedItem[] in UI
+- 🔄 Update GroupChildrenEditor to work with UnifiedRecipe directly
+
+#### Step 6: Utility Updates
+- 🔄 Update macro calculation utilities to work transparently with UnifiedItem[]
+- 🔄 Update conversion utilities to work with UnifiedRecipe
+
+### 📋 Remaining Steps
+
+#### Step 7: Complete Migration
+- ⏳ Update all Recipe usages in application layer to use UnifiedRecipe
+- ⏳ Add migration documentation for developers
+- ⏳ Update any remaining references to legacy Item[] recipes
+
+#### Step 8: Validation and Cleanup
+- ⏳ Run full integration tests to ensure UI works end-to-end
+- ⏳ Validate that database persistence still works correctly
+- ⏳ Clean up any unused code or temporary compatibility layers
+
+### Current State
+The Recipe entity now supports both legacy Item[] and new UnifiedItem[] operations:
+- **Database**: Still stores Item[] format for compatibility ✅
+- **In-Memory**: Can use UnifiedItem[] for all operations ✅  
+- **Conversion**: Automatic conversion between formats ✅
+- **Operations**: Full UnifiedItem[] recipe operations available ✅
+- **UI Components**: UnifiedRecipeEditView for native UnifiedItem[] operations ✅
+- **Macro Calculations**: Support for both Recipe and UnifiedRecipe ✅
+- **Legacy UI**: Still uses legacy Item[] operations (for compatibility) ⚠️
+- **Note on Deprecated Types:** While the migration for new development is complete, some core domain operations (e.g., in `src/modules/diet/item-group/domain/itemGroupOperations.ts` and `src/modules/diet/recipe/domain/recipeOperations.ts`) still interact with the deprecated `Item` type. This is a deliberate decision to maintain backward compatibility and support existing data structures until the next major version release, at which point the full deprecation and removal of the `Item` type will be finalized. This approach ensures a smooth transition without breaking existing functionalities.
+- **Application Layer**: Needs migration to use UnifiedRecipe natively 🚧
+
+## Phase 3 Completed: UI Layer Support ✅
+
+### Added Components:
+1. **UnifiedRecipeEditView**: Native UnifiedItem[] component without manual conversions
+2. **UnifiedRecipeEditContext**: Context provider for UnifiedRecipe operations
+3. **Macro Calculation Updates**: `calcUnifiedRecipeMacros()` and `calcUnifiedRecipeCalories()`
+
+### Key Benefits:
+- No manual Item[] ↔ UnifiedItem[] conversions in UI code
+- Direct use of unifiedRecipeOperations for all recipe modifications
+- Copy/paste operations work directly with UnifiedItem[] arrays
+- Cleaner component code with consistent data types
+
+## Phase 4: Application Layer Migration ✅ (Complete)
+
+### Completed Migrations:
+1. **GroupChildrenEditor**: Migrated to use UnifiedRecipe workflow
+   - Uses `saveUnifiedRecipe()` instead of `insertRecipe()`
+   - Creates UnifiedRecipe directly from UnifiedItem[] children
+   - Removes conversion functions (no Item[] ↔ UnifiedItem[] conversion needed)
+   - Demonstrates complete end-to-end UnifiedRecipe workflow
+
+2. **UnifiedItemName**: Migrated to use UnifiedRecipe API
+   - Uses `fetchUnifiedRecipeById()` instead of legacy repository
+   - Uses `convertUnifiedRecipeToRecipe()` for backward compatibility
+   - Maintains all existing functionality (manual edit detection)
+   - Shows pattern for gradual migration with conversion bridges
+
+### Key Benefits Demonstrated:
+- **No Data Conversion**: Direct UnifiedItem[] to UnifiedRecipe creation
+- **Cleaner Code**: Removed 15+ lines of conversion logic per component
+- **Type Safety**: Full type safety from UI to persistence
+- **Performance**: Eliminates conversion overhead in primary workflows
+- **Maintainability**: Single data model throughout most flows
+- **Backward Compatibility**: Legacy comparison logic continues to work via conversion utilities
+
+### Migration Patterns Established:
+
+#### Pattern 1: Pure UnifiedRecipe Workflow (GroupChildrenEditor)
+- Use UnifiedRecipe types throughout
+- No conversions needed
+- Cleanest implementation
+
+#### Pattern 2: Hybrid Workflow (UnifiedItemName)  
+- Use UnifiedRecipe API for fetching
+- Convert to legacy Recipe format for complex legacy logic
+- Maintains compatibility while using modern services
+
+### Reference Implementations:
+1. **GroupChildrenEditor**: Canonical example of pure UnifiedRecipe workflow
+2. **UnifiedItemName**: Example of hybrid approach with backward compatibility
+
+## Migration Status Summary ✅
+
+### ✅ COMPLETED PHASES:
+
+#### Phase 1: Domain Layer ✅
+- ✅ UnifiedRecipe and NewUnifiedRecipe types
+- ✅ UnifiedRecipe factory functions
+- ✅ Full unifiedRecipeOperations suite (16+ operations)
+- ✅ Conversion utilities (UnifiedRecipe ↔ Recipe, UnifiedItem[] ↔ Item[])
+- ✅ Comprehensive test coverage (16+ test cases)
+
+#### Phase 2: Infrastructure Layer ✅  
+- ✅ UnifiedRecipeRepository interface
+- ✅ supabaseUnifiedRecipeRepository implementation
+- ✅ Automatic conversion at persistence boundary
+- ✅ Database still stores Item[] format (compatibility preserved)
+
+#### Phase 3: Application Layer ✅
+- ✅ unifiedRecipe application service (all CRUD operations)

+- ✅ UnifiedRecipeEditView component (native UnifiedItem[] operations)
+- ✅ UnifiedRecipeEditContext (context provider for UnifiedRecipe)
+- ✅ Practical migrations: GroupChildrenEditor, UnifiedItemName
+- ✅ Migration patterns established for different use cases
+
+
+
+## Phase 5: Optional Future Enhancements 📋
+
+The migration is complete, but these optional enhancements could be considered:
+
+### Optional Additional Migrations:
+1. **RecipeEditModal**: Migrate to use UnifiedRecipeEditView  
+2. **Search Integration**: Update recipe search to prefer UnifiedRecipe services
+3. **Additional UI Components**: Migrate remaining Recipe-using components
+
+### System Improvements:
+1. **Performance Optimization**: Add caching for recipe conversions
+2. **Enhanced Validation**: Add runtime validation for UnifiedRecipe operations
+3. **Documentation**: Create developer guide for using UnifiedRecipe
+4. **Deprecation Plan**: Phase out legacy Recipe operations gradually
+
+## Success Metrics ✅
+
+### Technical Achievements:
+- ✅ **Zero Breaking Changes**: All existing functionality preserved
+- ✅ **Type Safety**: Full TypeScript support for UnifiedRecipe workflows  
+- ✅ **Performance**: Eliminated manual conversions in new workflows

+## **2. DOCS/ARCHITECTURE.md - Technical Decisions**
+
+```markdown
+# Architecture Decision Records
+
+## ADR-001: Unified Item/ItemGroup Model
+
+### Context
+The original system used separate `Item` and `ItemGroup` entities, creating complexity in meal composition and macro calculations.
+
+### Decision
+Implement a unified `UnifiedItem` model that can represent both individual items and recipe components.
+
+### Consequences
+- **Positive**: Simplified data model, reduced complexity
+- **Negative**: Requires migration of existing data
+- **Mitigation**: Implemented backward-compatible runtime migration
+
+## ADR-002: Runtime Migration Strategy

+
+### Decision
+Implement transparent runtime migration that converts legacy data format on-the-fly.
+
+### Implementation
+- Detection logic for legacy vs. new format
+- Automatic conversion during data fetching
+- Preservation of original data until explicit migration
+
+### Trade-offs
+- **Performance**: Additional processing per request
+- **Reliability**: Guaranteed backward compatibility
+- **Maintenance**: Migration code requires long-term support

-# Application Layer Audit
-
-## Overview
-The application layer orchestrates use cases, handles errors, and bridges domain and infrastructure. It should catch domain errors and call `handleApiError` with context.
-
-## Findings
-- **Error Handling:** Most application code follows the pattern, but some error propagation is inconsistent.
-- **Orchestration:** Some business logic may leak into UI or domain layers.
-- **Type Safety:** Application layer generally maintains strong typing.
-
-## Urgency
-- **High:** Audit all error handling for missing `handleApiError` context.
-- **Medium:** Review orchestration logic for business rule leakage.
-
-## Next Steps
-- List all application-layer entry points and check error handling.
-- Refactor orchestration logic to keep business rules in domain.
-- Expand audit to async flows and side effects.
-
-## Future Refinement Suggestions
-- Create `audit_application_<module>.md` for modules with complex orchestration.
-- Analyze async flows and error propagation in detail.
-- Review application-level test coverage and integration points.

-# Domain Layer Audit
-
-## Overview
-The domain layer is responsible for pure business logic, validation, and type safety. It should not contain side effects, error handling utilities, or infrastructure concerns.
-
-## Findings
-- **Schema/Type Logic:** Some domain files (e.g., `item.ts`, `dayDiet.ts`) include ID generation or type transformation logic that could be moved to infrastructure or application layers.
-- **Error Handling:** Domain code correctly avoids `handleApiError`, but custom error classes could be standardized for better context.
-- **Purity:** Most domain modules are pure, but some rely on legacy utilities (e.g., `generateId` in domain).
-
-## Urgency
-- **High:** Remove ID generation and side-effect utilities from domain code.
-- **Medium:** Standardize error types and schemas.
-
-## Next Steps
-- Audit all domain modules for side-effect imports.
-- Refactor ID and type logic to infrastructure.
-- Document domain error types and usage patterns.
-
-## Future Refinement Suggestions
-- Perform a per-module audit (e.g., diet, measure, profile) and create `audit_domain_<module>.md` files as needed.
-- Analyze domain model boundaries and invariants.
-- Review test coverage for domain logic.

 # Domain Layer Audit – High-Level Review
 
-_Last updated: 2025-06-07_
+_Last updated: 2025-07-08_
 
 ## General Assessment
 The codebase demonstrates a strong commitment to modularity and DDD-inspired organization, with clear separation between domain, application, and infrastructure layers in most modules. Each business area (diet, measure, user, etc.) is structured as a module, and most domain logic is isolated from side effects and technical concerns.

-# Diet Domain Audit – API Submodule
-
-_Last updated: 2025-06-07_
-
-## Overview
-This audit reviews the `api` submodule within the diet domain, focusing on DDD adherence, modularity, and architectural issues. It covers domain logic, schema usage, error handling, and test coverage.
-
-## Key Findings
-- **ID Generation:** API domain appears to use numeric IDs, but confirm that all ID generation is handled outside the domain.
-- **Schema/Type Logic:** Zod schemas are used for validation and transformation. Some transformation logic (e.g., setting `__type`) could be isolated for clarity.
-- **Repository Interface:** The domain may not define a repository interface for API models, which may limit testability and abstraction.
-- **Error Handling:** No direct use of `handleApiError` in domain, which is correct. However, there are no custom error classes for domain invariants or business rules.
-- **Test Coverage:** There may be a test file for API domain operations, but coverage of invariants and edge cases should be reviewed.
-
-## Urgency
-- **Medium:** Define a repository interface for API models in the domain layer if missing.
-- **Low:** Refactor transformation logic for clarity and add custom error classes for domain rules.
-
-## Next Steps
-- [ ] Confirm that all ID generation is handled outside the domain.
-- [ ] Define and document an `ApiModelRepository` interface in the domain if missing.
-- [ ] Add and document custom error types for domain invariants.
-- [ ] Review and improve test coverage for API domain logic.
-
-## Future Refinement Suggestions
-- Expand audit to cover cross-module dependencies (e.g., food, item).
-- Review Zod schema usage for separation of validation vs. transformation.
-- Propose stricter contracts for domain operations and invariants.

 # Diet Domain Audit – Food Submodule
 
-_Last updated: 2025-06-07_
+_Last updated: 2025-07-08_
 
 ## Overview
 This audit reviews the `food` submodule within the diet domain, focusing on DDD adherence, modularity, and architectural issues. It covers domain logic, schema usage, error handling, and test coverage.
 
 ## Key Findings
+- **Zod Schema for External API:** The `apiFoodModel.ts` uses `z.array(z.any())` for the `alimentos` field. While located in the infrastructure layer where `any` is permissible for untyped external APIs, consider if a more specific (even if flexible) Zod schema could be defined to improve type safety and clarity, reflecting the expected structure of the external data.
+
 - **ID Generation:** Food domain appears to use numeric IDs, but confirm that all ID generation is handled outside the domain.
 - **Schema/Type Logic:** Zod schemas are used for validation and transformation. Some transformation logic (e.g., setting `__type`) could be isolated for clarity.
 - **Repository Interface:** The domain defines a `FoodRepository` interface, which is good for abstraction and testability. Review for strict contracts and nullability.

-## Overview
-This audit reviews the `item-group` submodule within the diet domain, focusing on DDD adherence, modularity, and architectural issues. It covers domain logic, schema usage, error handling, and test coverage.
-
-## Key Findings
-- **ID Generation in Domain:** `itemGroup.ts` uses `generateId` from `~/legacy/utils/idUtils`, which is a side effect and breaks DDD purity. ID generation should be moved to infrastructure or application.
-- **Schema/Type Logic:** Zod schemas are used for validation and transformation, but transformation logic (e.g., setting `__type`) could be isolated for clarity. There are TODOs for recursive schemas and future-proofing discriminated unions.
-- **Repository Interface:** The domain does not define a repository interface for item-groups, which may limit testability and abstraction.
-- **Error Handling:** No direct use of `handleApiError` in domain, which is correct. However, there are no custom error classes for domain invariants or business rules.
-- **Test Coverage:** There is a test file for item-group operations, but coverage of invariants and edge cases should be reviewed.
-
-## Urgency
-- **High:** Remove all ID generation and legacy utility usage from domain code.
-- **Medium:** Define a repository interface for item-groups in the domain layer.
-- **Low:** Refactor transformation logic for clarity and add custom error classes for domain rules.
-
-## Next Steps
-- [ ] Refactor ID generation to infrastructure/application.
-- [ ] Audit all domain files for legacy/shared utility imports.
-- [ ] Define and document an `ItemGroupRepository` interface in the domain.
-- [ ] Add and document custom error types for domain invariants.
-- [ ] Review and improve test coverage for item-group domain logic.
-
-## Future Refinement Suggestions
-- Expand audit to cover cross-module dependencies (e.g., meal, recipe).
-- Review Zod schema usage for separation of validation vs. transformation.
-- Propose stricter contracts for domain operations and invariants.

-# Profile Domain Audit
-
-_Last updated: 2025-06-07_
-
-## Overview
-This audit reviews the `profile` module for DDD adherence, modularity, and architectural issues. The module currently only contains an application layer (`profile.ts`), with no explicit domain or infrastructure layers.
-
-## Key Findings
-- **Domain Layer Absence:** There is no explicit domain layer for profile logic. All logic is handled in the application layer, which may lead to mixing business rules with orchestration and UI concerns.
-- **Schema/Type Logic:** No domain schemas or types are defined for profile entities, which may reduce type safety and clarity.
-- **Error Handling:** Error handling is likely performed in the application layer, but without a domain layer, business rule errors may not be clearly separated.
-- **Test Coverage:** Test files for profile logic are not present in the domain or application layer.
-
-## Urgency
-- **High:** Define a domain layer for profile logic to separate business rules from orchestration and UI.
-- **Medium:** Introduce schemas/types for profile entities and operations.
-- **Low:** Add test coverage for profile domain logic once established.
-
-## Next Steps
-- [ ] Design and implement a domain layer for profile logic.
-- [ ] Define and document schemas/types for profile entities.
-- [ ] Refactor application logic to delegate business rules to the domain layer.
-- [ ] Add and improve test coverage for profile domain logic.

 # Sections/UI Layer Audit
 
+_Last updated: 2025-07-08_
+
 ## Overview
-Sections and UI components should focus on presentation and user interaction, delegating business logic to application/domain layers.
+Sections and UI components now exclusively use the unified item system for all item, group, and recipe flows. All legacy section-specific item/group components and context providers have been removed. Business logic (validation, macro overflow, clipboard, ID management) is centralized in unified components and shared utilities.
+
+## Unified System Migration (Completed)
+- **Removed:** All legacy item, item-group, and related view/edit components from sections (e.g., `ItemView`, `ItemEditModal`, `ItemGroupView`, `ItemListView`, `ExternalItemEditModal`, context providers)
+- **Migrated:** All section flows now use `UnifiedItemView`, `UnifiedItemEditModal`, and `UnifiedItemListView` for all item types
+- **Centralized:** Clipboard, validation, and macro logic are now handled in unified utilities and components
+- **Improved:** Type safety and maintainability through shared conversion utilities and type guards
+- **Reduced:** Prop drilling and code duplication across sections
 
-## Findings
-- **Duplication:** Notable code duplication between `MealEditView` and `RecipeEditView` (clipboard logic, schema validation, etc.).
-- **Business Logic Leakage:** Some validation and orchestration logic present in UI components.
-- **Naming:** Most components are well-named, but some generic names remain.
+## Key Findings
+- **Duplication Eliminated:** All major duplication between meal, recipe, item, and group flows has been resolved
+- **Business Logic Centralization:** Validation, macro overflow, and clipboard logic are now centralized
+- **Type Safety:** All conversions and type guards are handled by shared utilities
+- **Legacy Utility Removal:** Most legacy utilities and context providers have been removed; remaining usage is isolated
+- **Test Coverage:** All section tests now use unified item factories and conversion utilities
 
 ## Urgency
-- **High:** Refactor duplicated logic into shared utilities or hooks.
-- **Medium:** Move business logic out of UI components.
+- **Low:** Monitor unified system performance and optimize as needed
 
 ## Next Steps
-- Identify all duplicated logic in sections/components.
-- Propose shared abstractions for clipboard/schema logic.
-- Audit all UI components for business logic leakage.
+- [ ] Continue migration of any remaining legacy utilities
+- [ ] Monitor unified system performance and optimize as needed
+- [ ] Expand audits to cover async flows, error propagation, and cross-module dependencies
+- [ ] Review and improve test coverage for all modules and shared utilities
 
 ## Future Refinement Suggestions
-- Create `audit_sections_<section>.md` for complex or problematic sections.
-- Review UI boundaries and prop drilling.
-- Analyze UI test coverage and integration with application layer.
+- Monitor usage patterns and consider further optimizations as needed
+- Expand audit to cover context usage and state management patterns in the unified system
+- Continue strengthening boundaries between UI, application, and domain layers

-# Sections Audit – Common Section
-
-_Last updated: 2025-06-07_
-
-## Overview
-This audit reviews the `common` section UI components, focusing on separation of concerns, code duplication, and DDD alignment. The common section provides shared UI elements (e.g., modals, buttons, inputs, icons) used across multiple sections.
-
-## Key Findings
-- **Separation of Concerns:** Components (e.g., `ClipboardActionButtons`) are focused on UI presentation and delegate logic to props/callbacks, which is good practice.
-- **Reusability:** Common components are designed for reuse and composability across the codebase.
-- **Duplication:** No significant duplication observed within the common section, but ensure shared logic (e.g., clipboard, modal state) is not re-implemented in consuming sections.
-- **Component Boundaries:** Components are well-structured, with clear separation between UI and logic. State and effects are managed outside, via hooks or parent components.
-
-## Urgency
-- **Low:** Continue to ensure all logic is handled in the application layer or hooks, not in UI components.
-
-## Next Steps
-- [ ] Audit all common section components for unnecessary logic or duplication.
-- [ ] Review and improve test coverage for shared UI components.
-
-## Future Refinement Suggestions
-- Consider expanding the set of shared hooks/utilities if common logic is identified in consuming sections.
-- Expand audit to cover context usage and state management patterns.
-- Propose stricter boundaries between UI, application, and domain layers if needed.

-# Sections Audit – Datepicker Section
-
-_Last updated: 2025-06-07_
-
-## Overview
-This audit reviews the `datepicker` section UI components, focusing on separation of concerns, code duplication, and DDD alignment.
-
-## Key Findings
-- **Business Logic Leakage:** Some date parsing, formatting, and range logic is handled directly in UI components (e.g., `Datepicker.tsx`), rather than being abstracted into hooks or utility modules.
-- **Legacy/External Utility Usage:** Components use external libraries (e.g., `dayjs`) and custom helpers for date manipulation, which is appropriate, but some logic could be further isolated for clarity and reuse.
-- **Component Boundaries:** Components are generally well-structured, with clear separation of concerns, but some state and effect management could be moved to hooks for testability.
-- **Duplication:** Date formatting and range logic may be duplicated across datepicker and other sections (e.g., day-diet, profile).
-
-## Urgency
-- **Medium:** Refactor date parsing, formatting, and range logic into shared hooks/utilities for reuse and testability.
-- **Low:** Review and clarify component boundaries and state management.
-
-## Next Steps
-- [ ] Refactor date logic into shared hooks/utilities.
-- [ ] Audit all datepicker section components for business logic leakage and duplication.
-- [ ] Review and improve test coverage for UI logic.
-
-## Future Refinement Suggestions
-- Consider unifying date logic if used in multiple sections.
-- Expand audit to cover context usage and state management patterns.

-# Sections Audit – Day-Diet Section
-
-_Last updated: 2025-06-07_
-
-## Overview
-This audit reviews the `day-diet` section UI components, focusing on separation of concerns, code duplication, and DDD alignment.
-
-## Key Findings
-- **Business Logic Leakage:** Components (e.g., `DayMacros`) directly use legacy utilities and perform calculations (macros, calories, macro targets) in the UI layer, rather than delegating to the application layer.
-- **Legacy Utility Usage:** UI components import legacy utilities (e.g., `macroMath`), which should be abstracted away.
-- **Component Boundaries:** Components are generally well-structured, but some state and calculation logic could be moved to hooks or the application layer for clarity and testability.
-- **Duplication:** Some calculation and progress logic may be duplicated across day-diet and other sections (e.g., profile, macro-nutrients).
-
-## Urgency
-- **High:** Move business logic (calculations, macro state) out of UI components and into the application layer or custom hooks.
-- **Medium:** Refactor legacy utility usage to use application/domain abstractions.
-- **Low:** Review and clarify component boundaries and prop drilling.
-
-## Next Steps
-- [ ] Refactor business logic into application layer or custom hooks.

-# Sections Audit – EAN Section
-
-_Last updated: 2025-06-07_
-
-## Overview
-This audit reviews the `EAN` section UI components, focusing on separation of concerns, code duplication, and DDD alignment.
-
-## Key Findings
-- **Business Logic Leakage:** Components (e.g., `EANReader`) handle scanner configuration, error handling, and EAN format validation directly in the UI layer. Some of this logic could be abstracted into hooks or the application layer for clarity and reuse.
-- **Error Handling:** Uses a shared error handler for scanner errors, which is good, but error context and user feedback could be standardized.
-- **Component Boundaries:** Components are generally well-structured, but scanner setup and teardown logic could be further isolated.
-- **Duplication:** Scanner and EAN handling logic may be duplicated if EAN reading is used in other sections.
-
-## Urgency
-- **Medium:** Move scanner configuration and EAN validation logic into hooks or the application layer for reuse and testability.
-- **Low:** Standardize error handling and user feedback for scanner errors.
-
-## Next Steps
-- [ ] Refactor scanner and EAN logic into shared hooks/utilities.
-- [ ] Standardize error handling and user feedback for scanner errors.

-# Shared & Legacy Audit
-
-## Overview
-Shared and legacy code provides utilities, error handling, and migration support. It should not break DDD boundaries or introduce side effects into domain/application layers.
-
-## Findings
-- **Legacy Utilities:** Some legacy utilities (e.g., `idUtils`, `supabase`) are still used in domain and application code.
-- **Error Handling:** `handleApiError` is correctly isolated, but some shared code is imported inappropriately.
-- **Migration:** The `legacy/` folder is under migration, but boundaries are not always clear.
-
-## Urgency
-- **High:** Remove legacy utility usage from domain code.
-- **Medium:** Clarify migration plan and document shared module boundaries.
-
-## Next Steps
-- List all imports from `legacy/` and `shared/` in domain/application layers.
-- Propose migration steps for remaining legacy utilities.
-- Document shared module responsibilities and allowed usage.
-
-## Future Refinement Suggestions
-- Create `audit_shared_legacy_<utility>.md` for complex or high-risk utilities.
-- Map all shared/legacy code usage across the codebase.
-- Review shared code test coverage and migration blockers.

+# QA Notes for Issue #730 Refactoring
+
+## Strange Observations:
+
+- **Persistent 'Initializing app...' message:** The application displays 'Initializing app...' even after macro targets are set and the `MacroTargetNotFoundForDayError` is resolved. This seems to be related to a failed image load from Supabase storage (`https://sbhhxgeaflzmzpmatnir.supabase.co/storage/v1/object/public/uploads/3.jpg`), resulting in a `net::ERR_NAME_NOT_RESOLVED` error. This error is being ignored for the purpose of functional QA.
+
+## Test Results:
+
+### TEST MP-01: Validation of Non-Negative Values
+- **Result:** FAIL
+- **Expected:** Display message "The 'gramsPerKgCarbs' field of the macro profile must be a non-negative number" below the field.
+- **Actual:** No validation message appeared.
+
+### TEST MP-02: Data Type Validation
+- **Result:** PARTIAL PASS (Browser native validation prevents non-numeric input)
+- **Expected:** Display message "The 'gramsPerKgProtein' field of the macro profile must be a number" below the field.
+- **Actual:** Browser's native validation prevented typing "abc" into the number input field. No application-level validation message was displayed. This is a positive behavior as it prevents invalid data entry at the browser level.
+
+### TEST MP-03: Reactive Macro Calculation
+- **Result:** FAIL (Calculation error)
+- **Expected:** Update INSTANTANEOUSLY the value "kcal" (from 450 to 900) and the percentage without reloading page.
+- **Actual:** The "kcal" value for fat updated from 630 kcal to 900 kcal, which is correct. However, the total "Daily caloric goal" changed from 1630 kcal to 2030 kcal, which is incorrect (should be 1900 kcal). The percentage for fat also changed from 38.65% to 39.13%, which is incorrect for 900 kcal out of 1900 kcal (should be 47.3%). This indicates a calculation error.
+
+### TEST W-01: Negative Weight Validation
+- **Result:** FAIL
+- **Expected:** Display toast red message "The 'weight' field of the weight must be a non-negative number".
+- **Actual:** No toast message appeared.
+
+### TEST W-02: Data Type Validation
+- **Result:** FAIL
+- **Expected:** Display toast red message "The 'weight' field of the weight must be a number".
+- **Actual:** No toast message appeared.
+
+### TEST W-03: Empty Field Validation
+- **Result:** FAIL
+- **Expected:** Display toast red message "Enter a weight".
+- **Actual:** No toast message appeared.
