Walkthrough

Introduces a DM ID-based guard in group webhook processing to skip DM-derived groups and marks webhooks completed. Updates chat/group description strings to embed a “DM ID: {userId}::{dreamsyncUser.id}” pattern during mutual chat creation. No public API/signature changes.

Changes

Cohort / File(s)	Summary
DM-derived group early-exit guards platforms/dreamsync-api/src/controllers/WebhookController.ts, platforms/dreamsync-api/src/web3adapter/watchers/subscriber.ts	Add checks to skip processing when group description starts with "DM ID:"; logs and returns early (200 in controller), mirroring existing Match ID safeguards.
DM ID-based metadata for mutual chats platforms/dreamsync-api/src/services/ConsentService.ts, platforms/dreamsync-api/src/services/MatchNotificationService.ts	Replace generic chat/group descriptions with "DM ID: {userId}::{dreamsyncUser.id}" and update chat name to include targetUserId; no control-flow or signature changes.

Poem

I thump my paw—DMs in the dew,
A tidy tag: “DM ID” guides us through.
Webhooks hop past déjà-vu lanes,
Chats renamed with breadcrumb chains.
Carrot logs crisp, the garden clean—
Early exits swift and lean.
Onward, ears up, code serene.
