Act as: Expo + Supabase Edge Function Cold Start & Mobile Performance Analysis

Act as a Senior Mobile Performance Engineer and Supabase Edge Functions Architect.

Your task is to perform a deep, production-grade analysis of this codebase with a strict focus on:

- Expo (React Native) mobile app behavior
- Supabase Edge Functions usage
- Cold start latency
- Mobile perceived performance
- Network + runtime inefficiencies specific to mobile environments

This is NOT a refactor task.
This is an ANALYSIS + DIAGNOSTIC task.
Do not write code unless explicitly requested.
Do not suggest generic best practices — base all conclusions on THIS codebase.

---

## 1. CONTEXT & ASSUMPTIONS

Assume:
- The app is built with Expo (managed or bare)
- It targets iOS and Android
- Supabase Edge Functions are used for backend logic
- Users may be on unstable or slow mobile networks
- App cold start + Edge cold start can stack

Edge Functions run on Deno and are serverless.

---

## 2. ANALYSIS OBJECTIVES

You must identify and document:

### A. Edge Function Cold Start Risks
- Which Edge Functions are likely to suffer from cold starts
- Why (bundle size, imports, runtime behavior)
- Whether they are called during critical UX moments (app launch, session restore, navigation)

### B. Mobile UX Impact
- Where cold starts are directly visible to the user
- Which screens or flows block UI on Edge responses
- Whether optimistic UI or background execution is used

### C. Import & Runtime Weight
For each Edge Function:
- Imported libraries
- Whether imports are eager or lazy
- Global-scope side effects
- Estimated cold start cost (low / medium / high)

### D. Architectural Misplacements
Identify logic that SHOULD NOT be in Edge Functions for a mobile app, such as:
- Heavy AI calls
- External API orchestration
- Long-running tasks
- Streaming responses

Explain why each case is problematic specifically for mobile users.

---

## 3. EDGE FUNCTION CLASSIFICATION

For each Edge Function, classify it into ONE of these roles:

- Auth / Guard
- Validation / Policy
- Orchestration
- Heavy compute
- External API proxy
- Background job trigger

Then answer:
- Is Edge the correct runtime for this role?
- Should it be Edge, Server, or Worker?

---

## 4. MOBILE-SPECIFIC FLOW ANALYSIS

Trace the following flows end-to-end:

- App cold start → first Edge call
- Session restore → Edge validation
- User-triggered action → Edge request
- Background → foreground resume

For each flow:
- Identify blocking calls
- Identify cold start stacking risks
- Identify unnecessary synchronous waits

---

## 5. PERFORMANCE & LATENCY BUDGET

Estimate (qualitatively, not numerically):

- Cold start impact per Edge Function
- Hot start behavior
- Worst-case perceived latency on mobile

Use categories:
- Invisible
- Noticeable
- UX-breaking

---

## 6. FINDINGS FORMAT (MANDATORY)

Output your findings in the following structure:

### 🔴 Critical Issues
Issues that directly harm mobile UX.

### 🟠 Moderate Risks
Issues that scale poorly or affect retention.

### 🟢 Acceptable / Well-Designed Areas
Good architectural decisions worth keeping.

---

## 7. RECOMMENDATIONS (STRICT RULES)

- Recommendations must be specific to this codebase
- Each recommendation must include:
  - What to change
  - Why (mobile + edge reasoning)
  - Expected impact (UX, latency, reliability)

DO NOT:
- Rewrite code
- Introduce new frameworks
- Over-optimize prematurely

---

## 8. FINAL VERDICT

Answer explicitly:
- Is this architecture mobile-appropriate?
- Is Edge overused, underused, or correctly used?
- What is the single highest-impact improvement?

---

## IMPORTANT RULES

- Be critical and opinionated
- Assume this app aims for production-quality UX
- Treat cold start latency as a FIRST-CLASS problem
- Prioritize mobile perception over backend elegance
