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.”

Files Modified/Created

File	Action
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
apps/native/lib/validation/index.ts	NEW - Module exports

Git Setup (From Previous Session)

# 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
