From a86d304f0724f6554f0cac626cdf0cd6e6051cce Mon Sep 17 00:00:00 2001 From: Jason Woltje Date: Sat, 31 Jan 2026 14:01:42 -0600 Subject: [PATCH] feat(#139): build Gate Rejection Response Handler Implement rejection handling for tasks that fail quality gates after all continuation attempts are exhausted. Schema: - Add TaskRejection model for tracking rejections - Store failures, attempts, escalation state Service: - handleRejection: Main entry point for rejection handling - logRejection: Database logging - determineEscalation: Rule-based escalation determination - executeEscalation: Execute escalation actions - sendNotification: Notification dispatch - markForManualReview: Flag tasks for human review - getRejectionHistory: Query rejection history - generateRejectionReport: Markdown report generation Escalation rules: - max-attempts: Trigger after 3+ attempts - time-exceeded: Trigger after 2+ hours - critical-failure: Trigger on security/critical issues Actions: notify, block, reassign, cancel Tests: 16 passing with 80% statement coverage Fixes #139 Co-Authored-By: Claude Opus 4.5 --- apps/api/prisma/schema.prisma | 23 + apps/api/src/rejection-handler/index.ts | 3 + .../interfaces/escalation.interface.ts | 13 + .../src/rejection-handler/interfaces/index.ts | 2 + .../interfaces/rejection.interface.ts | 25 + .../rejection-handler.module.ts | 10 + .../rejection-handler.service.spec.ts | 442 ++++++++++++++++++ .../rejection-handler.service.ts | 408 ++++++++++++++++ 8 files changed, 926 insertions(+) create mode 100644 apps/api/src/rejection-handler/index.ts create mode 100644 apps/api/src/rejection-handler/interfaces/escalation.interface.ts create mode 100644 apps/api/src/rejection-handler/interfaces/index.ts create mode 100644 apps/api/src/rejection-handler/interfaces/rejection.interface.ts create mode 100644 apps/api/src/rejection-handler/rejection-handler.module.ts create mode 100644 apps/api/src/rejection-handler/rejection-handler.service.spec.ts create mode 100644 apps/api/src/rejection-handler/rejection-handler.service.ts diff --git a/apps/api/prisma/schema.prisma b/apps/api/prisma/schema.prisma index efe806e..5413525 100644 --- a/apps/api/prisma/schema.prisma +++ b/apps/api/prisma/schema.prisma @@ -1030,3 +1030,26 @@ model QualityGate { @@index([workspaceId, isEnabled]) @@map("quality_gates") } + +model TaskRejection { + id String @id @default(uuid()) @db.Uuid + taskId String @map("task_id") + workspaceId String @map("workspace_id") + agentId String @map("agent_id") + attemptCount Int @map("attempt_count") + failures Json // FailureSummary[] + originalTask String @map("original_task") + startedAt DateTime @map("started_at") @db.Timestamptz + rejectedAt DateTime @map("rejected_at") @db.Timestamptz + escalated Boolean @default(false) + manualReview Boolean @default(false) @map("manual_review") + resolvedAt DateTime? @map("resolved_at") @db.Timestamptz + resolution String? + + @@index([taskId]) + @@index([workspaceId]) + @@index([agentId]) + @@index([escalated]) + @@index([manualReview]) + @@map("task_rejections") +} diff --git a/apps/api/src/rejection-handler/index.ts b/apps/api/src/rejection-handler/index.ts new file mode 100644 index 0000000..25d0585 --- /dev/null +++ b/apps/api/src/rejection-handler/index.ts @@ -0,0 +1,3 @@ +export * from "./rejection-handler.module";
