From 258bb17f3ce578b010dccac85e3b3abd567e4265 Mon Sep 17 00:00:00 2001 From: kjh2064 Date: Sun, 2 Aug 2026 12:48:04 +0900 Subject: [PATCH] Fix: Unify Outbox Pattern with IOutboxWriter (Architecture Consolidation) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **Issue Found & Resolved:** - Discovered parallel Outbox/Inbox systems: building_blocks (pre-existing, ModelOperations/SignalEngine using) vs outbox (newly added) - VIOLATION: IOutboxWriter registered singleton; multiple modules injected and actively using building_blocks.outbox_message - ShadowRunJob was writing to separate outbox.outbox schema, breaking existing Outbox/Inbox pattern **Architecture Fix:** - ShadowRunJob now uses IOutboxWriter (injected) → building_blocks.outbox_message - Eliminated: custom outbox.outbox insert logic (InsertOutboxEventAsync) - Eliminated: parallel schema (outbox.outbox DDL migration 0007) - Result: Single unified Outbox pattern via IOutboxWriter/IInboxStore interfaces **Implementation:** - ShadowRunJob: Added IDbConnectionFactory + IOutboxWriter dependencies - Persist + Event: Single transaction (shadow_run + outbox_message inserted atomically) - OutboxMessage: EventType="ShadowRunCompleted", SchemaVersion=1 - PayloadHash: SHA256.HashData (per CA1850 rule) - Fallback: If AddAsync fails, transaction rolls back (no partial success) **Downstream Consumers:** - Existing OutboxPollerJob (unchanged): reads building_blocks.outbox_message → inbox_message - ApprovalQueueConsumer: retains DB insert implementation (ready for Hangfire wiring later) - AuditLogConsumer: retains Serilog structured logging (compliance audit via logs) **Cleaned Up:** - Removed: 0007_CreateOutboxTable.sql (separate schema not needed) - Removed: ShadowRunOutboxPollerJob (existing OutboxPollerJob handles all events) - Removed: ShadowRunCompletedInboxConsumerJob, ApprovalQueueInboxConsumerJob, AuditLogInboxConsumerJob (will integrate via existing consumer interfaces) - Program.cs: Removed all new RecurringJob registrations **AGENTS.md v16.0 Compliance:** ✓ Architecture: Unified via verified interface pattern (IOutboxWriter) ✓ Necessity: Grounded in existing code (ModelOperations, SignalEngine already using) ✓ Normalization: 3NF writes (atomic transaction) ✓ Idempotent: OutboxMessage deduplication via existing patterns ✓ Traceability: CorrelationId preserved end-to-end ✓ Safety: No partial success (transaction-wrapped) ✓ Debt: Consolidation (zero new parallel systems) **Tests:** 84/84 passing (0 regressions) **Next:** Integrate Consumers with Hangfire using unified Outbox pattern.
