v0.42.0 Release Recap

v0.42.0 is a non-breaking review workflow release that adds explicit synchronous execution for review handoff webhooks.

What Changed

Area	New in v0.42.0	Why it matters
Go SDK execution	ReviewHandoffWebhookDeliver	Lets clients send saved handoff snapshots after explicitly opting in with Execute: true
REST execution	POST /v1/namespaces/{ns}/review/handoff-webhooks/deliver	Gives operators a controlled HTTP delivery path with timeout and response capture
GraphQL execution	deliverReviewHandoffWebhook(...)	Gives debugger UIs and automation tools a mutation for push-style handoff delivery
Feature metadata	review-handoff-webhook-execution	Lets live deployments advertise explicit handoff webhook execution support

Compatibility

This release only adds an opt-in execution path. Dry-run planning remains unchanged, and execution does not add background retries, queues, or stored delivery receipts.

Operator Flow

curl -X POST http://localhost:7701/v1/namespaces/my-app/review/handoff-webhooks/deliver \
  -H 'Content-Type: application/json' \
  -d '{
    "owner": "alice",
    "escalation_level": "review_overdue",
    "target_url": "https://ops.example.test/contextdb/handoffs",
    "secret": "webhook-signing-secret",
    "execute": true,
    "timeout_ms": 5000
  }'

Each matching saved handoff is sent as one synchronous POST. The response records executed, status_code, response_body, and error for each delivery.
