Introduce a notifications subsystem for LWS with three channels: Server-Sent Events, WebSocket, and Webhooks. Key design decisions: - Single NotificationService with subscriptionType array - LWS-specific envelope wrapping Activity Streams 2.0 events - phase property (post-commit) for future admission controller extensibility - topic property for subscription targets (avoids items collision) - Webhook authentication via HTTP Message Signatures (RFC 9421) - inbox aligned with access-request-grant-proposal pattern Files: - lws10-notifications/index.html: New subspecification - lws10-core/Discovery.html: Updated NotificationService example - README.md: Added notifications to specs list
- Clarify MAY support / MUST advertise pattern for notifications - Make phase OPTIONAL, use PascalCase (PostCommit) - Remove forward references to future specifications - Add Subscriber to terminology, use consistently throughout - Add Subscription Scope section (recursive container subscriptions) - Add Subscription Authorization section (delivery-time authz, subcontainer filtering, authorization change handling) - Tighten object structure normatively (nested id/type requirements) - Add authentication verification relationship per CID 1.0 - Add Activity Streams 2.0 terms to vocabulary table - Add PostCommit as vocabulary term - Source external terms from CID-1.0 instead of generic Security Vocab
Replace the Webhook Endpoint term with Inbox — a URL controlled by a subscriber or other agent to which a server delivers notifications via HTTP POST. This aligns with the inbox concept used in the access-request-grant-proposal and makes the term reusable across LWS subspecifications.
Reference the lws10-notifications specification with a summary of the three notification channels (SSE, WebSocket, Webhooks) and shared data model.
Remove WebSocket and Server-Sent Event notification channels from the base notifications specification. These client-server streaming channels will be introduced in a separate specification. Remove the phase property from the notification envelope and subscription request. This concept may be re-introduced at a later point.

Resolves #103
This is a class 4 change to the protocol. It will need discussion and a WG vote before merging.
This PR introduces the base LWS Notifications specification, scoped to Webhook notifications only. Client-server streaming channels (WebSocket, Server-Sent Events) will be introduced in a follow-up PR (
notifications-streaming) that targets this branch.Changes:
