- POST/GET/PUT/DELETE /environments/{envSlug}/alerts/rules CRUD
- POST /{id}/enable, /{id}/disable, /{id}/render-preview, /{id}/test-evaluate
- Attribute-key validation: rejects keys not matching ^[a-zA-Z0-9._-]+$ at rule-save time
(CRITICAL: ExchangeMatchCondition attribute keys are inlined into ClickHouse SQL)
- Webhook validation: verifies outboundConnectionId exists and is allowed in env
- Null-safe notification template defaults to "" for NOT NULL DB constraint
- Fixed misleading comment in ClickHouseSearchIndex to document validation contract
- OPERATOR+ for mutations, VIEWER+ for reads
- Audit: ALERT_RULE_CREATE/UPDATE/DELETE/ENABLE/DISABLE with AuditCategory.ALERT_RULE_CHANGE
- 11 IT tests covering RBAC, SQL-injection prevention, enable/disable, audit, render-preview
