docs: Gemini confirms Arbiter lifecycle handlers NOT yet built

Arbiter 3.5.0 has:
✅ checkout.session.completed (new subscriptions)

Arbiter 3.5.0 does NOT have:
❌ Cancellation handling
❌ Grace period (3-day)
❌ Chargeback handling
❌ invoice.payment_failed handler
❌ subscription.cancelled handler
❌ 4 AM sweeper job

Task #87 remains HIGH PRIORITY for subscriber lifecycle.

+# Gemini Consultation: Arbiter 3.5.0 Feature Verification
+
+**Date:** April 4, 2026, 11:15 PM CDT  
+**From:** Michael (The Wizard) + Claude (Chronicler #59)  
+**To:** Gemini (Architectural Partner)  
+**Re:** Confirming what's implemented in Arbiter 3.5.0
+
+---
+
+## Hey Gemini! 👋
+
+Quick verification request. We're doing backlog cleanup and need to confirm what's actually in Arbiter 3.5.0 so we can archive completed tasks.
+
+## The Question
+
+**Task #87 (Arbiter 2.1)** was planned to add:
+1. Subscription cancellation handling
+2. Payment failure with 3-day grace period
+3. Chargeback handling (immediate permanent ban)
+4. "We Don't Kick People Out" philosophy (downgrade to Awakened, never remove)
+5. Stripe webhook handlers for `invoice.payment_failed`, `subscription.cancelled`, `chargeback.created`
+6. 4 AM grace period sweeper job
+
+**You wrote the code for Arbiter 3.5.0.**
+
+Can you confirm which of these features ARE implemented in the current production code?
+
+## What We Need
+
+A simple checklist:
+- [ ] or [x] for each feature
+- Any caveats or "partially implemented" notes
+- Anything that still needs work
+
+## Context
+
+- Arbiter 3.5.0 is deployed at `discord-bot.firefrostgaming.com`
+- Stripe webhooks configured at `/webhooks/stripe/webhook`
+- We went LIVE on April 3, 2026
+- No real subscribers yet to test the full flow
+
+---
+
+Thanks Gemini! 🔥❄️

+
+## Gemini's Response (April 4, 2026)
+
+**Summary:** The lifecycle handlers are NOT yet implemented.
+
+**What IS in Arbiter 3.5.0:**
+- ✅ `checkout.session.completed` webhook (Stateless OAuth Bridge, new subscriptions)
+
+**What is NOT in Arbiter 3.5.0:**
+- ❌ Subscription cancellation handling
+- ❌ Payment failure with 3-day grace period
+- ❌ Chargeback handling (immediate permanent ban)
+- ❌ "We Don't Kick People Out" downgrade logic
+- ❌ `invoice.payment_failed` handler
+- ❌ `subscription.cancelled` handler
+- ❌ `chargeback.created` handler
+- ❌ 4 AM grace period sweeper job
+
+**Gemini's Request:** Needs to see current webhook handler code and sweeper script to audit against Task #87 requirements.
+
+---
+
+## Conclusion
+
+**Task #87 (Arbiter 2.1 Cancellation Flow) is STILL NEEDED.**
+
+The Gemini-reviewed architecture and code blocks from March 30, 2026 are ready to implement. This remains a high-priority item for subscriber lifecycle management.
+
+**Next Steps:**
+1. Share webhook handler code with Gemini
+2. Implement the missing lifecycle handlers
+3. Test with real subscription events
