chore: wip reengagement campaign

[codenameakshay]

Implementation Complete

Cloud Functions (TypeScript) — functions/src/

reengagementCampaign.ts (new)

• Triggered by reengagementCampaigns/{campaignId} Firestore writes
• Segments all 267K users by lastActiveAt into hot/warm/cold/frozen buckets
• Sequence 1: sends push + email to all segments
• Sequence 2: filters to seq1 non-openers only; credits 50 Prism Coins via coinTransactions before sending
• Sequence 3: filters to seq2 non-openers only
• Respects emailOptOut and pushSuppressed flags per user
• Paginates in batches of 200 with cursor continuation (handles 267K users)

emailReengagement.ts (new)

• Writes to the mail Firestore collection (picked up by Firebase Trigger Email extension)
• 3 inline HTML email templates (announcement, coins, farewell)
• RFC 8058 List-Unsubscribe headers on every email (Gmail/Yahoo compliance)
• CTA links to prismwalls.com/reengagement?seq=N&source=email&uid=... which should handle the app-link redirect

reengagementStateTracker.ts (new)

• onReengagementEventCreated: triggered by reengagementEvents/{eventId} (written by the app on deep link tap); records seqNOpenedAt, handles unsubscribe
• onEmailUnsubscribeRequested: triggered by emailUnsubscribeRequests/{requestId} (written by the web unsubscribe page); sets emailOptOut on user doc

index.ts — exports 3 new functions

onCampaignNotificationRequested.ts — accepts optional campaignId + sequence fields for traceability

---

Flutter/Dart — lib/

lib/auth/userModel.dart — added emailOptOut: bool and pushSuppressed: bool fields (parsed from Firestore, defaulting to false). make file-gen regenerated the .g.dart file.

lib/features/deep_link/domain/entities/deep_link_action_entity.dart — added ReengagementIntent with sequence, source, userId

lib/core/router/deep_link_parser.dart — parses prism://reengagement?seq=N&source=X&uid=Y

lib/core/router/deep_link_navigation.dart — maps ReengagementIntent → AiTabRoute and writes a reengagementEvents doc for server-side state tracking

lib/notifications/localNotification.dart — handles reengagement payload on cold-start notification tap; navigates to AI tab and records the open event

---

What still needs to be done before launch

1. Install Firebase Extension: Trigger Email from Firestore — connects mail collection to SendGrid/Mailgun
2. Configure SendGrid: Add noreply@prismwalls.com as a verified sender domain
3. Web unsubscribe page: prismwalls.com/unsubscribe?token=...&uid=... — validates token, writes to emailUnsubscribeRequests
4. Web reengagement redirect: prismwalls.com/reengagement?seq=N&source=email&uid=... — handles app-link redirect to prism://reengagement
5. Deploy functions: firebase deploy --only functions
6. Trigger campaign: Admin writes { sequence: 1, segments: ["hot","warm","cold","frozen"] } to reengagementCampaigns collection

Tip

You can make CodeRabbit's review stricter and more nitpicky using the `assertive` profile, if that's what you prefer.

Change the reviews.profile setting to assertive to make CodeRabbit's nitpick more issues in your PRs.
