01 Notification Action Foundation

Branch

codex/v0.5-webhook-notification/01-notification-action-foundation

Start this branch from the chosen release base branch.

Create the backend foundation for project-scoped notification actions and delivery logs.

Add database tables for configured notification actions and delivery attempts.
Add models, factories, resources, enums, and reusable actions or services for notification action management.
A notification action belongs to a project.
A notification action has a name, enabled flag, event type, channel, channel configuration, optional message template, and secret delivery URL.
Supported event type for this release: ticket_status_changed.
Supported channels for this release: webhook and discord.
Store webhook and Discord URLs encrypted and hide them from serialized model/resource output.
Add delivery logs that can record action, event type, channel, delivery status, attempt count, HTTP status, response or error excerpt, payload metadata, and timestamps.
Keep the schema extensible for later event types and channels.

Notification action records can be created, updated, listed, and deleted through backend actions or services.
Secret URLs are encrypted at rest and are not exposed by resources.
Delivery log records can represent pending, succeeded, failed, and retryable attempts.
The foundation does not dispatch external HTTP requests yet.
Existing ticket, project, API, and MCP behavior is unchanged.

Model tests for relationships, casts, enum handling, and hidden secret URL output.
Factory tests or feature-backed assertions proving webhook and Discord action records can be created.
Action/service tests for create, update, delete, and project ownership behavior.
Delivery log tests for supported statuses and relationship integrity.
