From e239ff27f66314cac25e4963e6992cec60a4b7bc Mon Sep 17 00:00:00 2001 From: "Grace (Clawdbot)" Date: Tue, 27 Jan 2026 18:08:08 +0100 Subject: [PATCH] feat(exec-events): add top-level runId to payload - Added runId?: string to ExecEventBase type in exec-events.ts - Added runId to all three emitExecEvent calls (exec.started, exec.output, exec.completed) - Fixes Crabwalk mismatch where it expects exec.runId but Gateway sent context.runId - runId is sourced from session.execEvents.context?.runId for backward compatibility Resolves: Crabwalk exec nodes not displaying due to schema mismatch --- AUDIT_REPORT.md | 246 ++++++++++++++++++++++++++++++++++ CONTINUITY.md | 49 +++++++ src/agents/bash-tools.exec.ts | 3 + src/infra/exec-events.ts | 20 +-- 4 files changed, 308 insertions(+), 10 deletions(-) create mode 100644 AUDIT_REPORT.md create mode 100644 CONTINUITY.md diff --git a/AUDIT_REPORT.md b/AUDIT_REPORT.md new file mode 100644 index 000000000..260c6b5fb --- /dev/null +++ b/AUDIT_REPORT.md @@ -0,0 +1,246 @@ +# Exec Events E2E Audit Report + +**Date:** 2026-01-27 +**Auditor:** Grace (via Codex analysis) + +## Executive Summary + +The exec events flow is fundamentally working (Gateway emits β†’ WebSocket broadcasts β†’ Crabwalk receives), but **there's a critical `runId` schema mismatch** that prevents proper session linking. + +### Critical Finding +**Gateway sends `runId` nested in `context` object (optional);
