> Production-Level Validation Module & Frontend Improvements

# February 4th, 2026

**Building the Validation Foundation**

Today was focused on creating a robust, production-ready validation system for task drafts and improving the UI components to support proper error handling.

***

## What We Built Today

### 1. Time Set Screen Improvements (`time-set.tsx`)

| Change            | Details                                                     |
| ----------------- | ----------------------------------------------------------- |
| Save button logic | Now requires both days AND time slots to be enabled         |
| New derived state | `hasTimeSlots`, `canSave = hasDaysSelected && hasTimeSlots` |

### 2. Confirmation Modal Enhancement (`ConfirmationModal.tsx`)

| Change   | Details                                                    |
| -------- | ---------------------------------------------------------- |
| New prop | `singleButton?: boolean`                                   |
| Behavior | When true, hides cancel button, centers the confirm button |
| Use case | Error acknowledgement modals with just "Ok" button         |

### 3. Production-Level Validation Module (NEW FILES)

```
lib/validation/taskDraft.ts
├── Types
│   ├── ValidationResult (valid: true | false with error & errorCode)
│   └── ValidationErrorCode (TITLE_REQUIRED, TIME_REQUIRED, TIME_REQUIRES_X_CONDITION)
│
├── Validators
│   ├── validateTitle() - Checks title is non-empty
│   ├── validateTimeRequired() - Checks time condition exists
│   ├── validateTimeXRule() - Enforces Time + X rule
│   ├── hasCondition() - Helper to check metric in conditions
│   ├── hasPartnerCondition() - Check if partner assigned
│   └── hasAnyXCondition() - Check for any X condition
│
├── Main Entry Point
│   └── validateTaskDraft(draft) - Runs all checks in order
│
└── Utilities
    └── getConditionSummary() - Debug helper
```

```
lib/validation/index.ts
```

Central export file for clean imports.

### 4. Final Screen Validation (`final.tsx`)

| Change                | Details                                                          |
| --------------------- | ---------------------------------------------------------------- |
| Import                | `import { validateTaskDraft } from "@/lib/validation/taskDraft"` |
| `handleCommitPress()` | Uses centralized validation before showing confirm modal         |
| Error modal           | Shows validation errors with single "Ok" button                  |
| Confirm button text   | Dynamic: "Commit" for new, "Update" for edit mode                |

## Validation Rules Implemented

| Step | Check             | Error Message                                                                        |
| ---- | ----------------- | ------------------------------------------------------------------------------------ |
| 1    | Title required    | "Please enter a name for your commitment"                                            |
| 2    | Time required     | "Please set a time for your commitment"                                              |
| 3    | Time + X required | "Time + X combination is required. Please add Location, Partner, Picture, or Video." |

| `apps/native/app/(create-commit)/time-set.tsx`          | Modified - Save button logic        |
| `apps/native/app/(create-commit)/final.tsx`             | Modified - Validation + error modal |
| `apps/native/components/ui/modal/ConfirmationModal.tsx` | Modified - singleButton prop        |
| `apps/native/lib/validation/taskDraft.ts`               | NEW - Task draft validators         |

## Git Setup (From Previous Session)

```bash theme={null}
# Quick push command (in ~/.bashrc)
pp() { git add -A && git commit -m "$1" && git push origin HEAD:main; }

# Usage
pp "your commit message"

# Repo
https://github.com/Maajith9127/mono.git

# Branch: dev-maajith → pushes to main
```

## Convex Overview (For Next Session)

### Key Concepts Discussed

* `scheduler.runAt(timestamp, functionRef, args)` - Schedule function at specific time
* `scheduler.runAfter(delayMs, functionRef, args)` - Schedule after delay
* `internalMutation` / `internalAction` - Backend-only functions (for scheduled jobs)
* **Durability** - Jobs persist through restarts, auto-retry on failure
* **Limits** - 1M free function calls/month, 1M outstanding scheduled jobs

### Planned Architecture

```
User creates task → Save to DB → Calculate next occurrence 
→ Create taskInstance → Schedule check at deadline 
→ Scheduled function runs → Check if verified → Apply penalty or schedule next
```

***

## Next Steps

1. Look at current `tasks.ts` in `packages/backend/convex/`
2. Create `taskInstances` table - For individual occurrences
3. Implement recurrence calculation - Find next occurrence from rule
4. Add scheduling logic - Schedule verification check at deadline
5. Create `checkCompletion` internal function - Runs at deadline

## Key Takeaways

| Insight                         | Details                                                |
| ------------------------------- | ------------------------------------------------------ |
| Convex scheduler                | Durable, auto-retry, no Redis/BullMQ needed            |
| 1M free calls/month             | Enough for 10K+ users easily                           |
| Validation in `lib/validation/` | Testable, reusable, production-ready                   |
| Time + X rule                   | Time alone not valid, needs location/partner/pic/video |
