jaeko44 · 2026-03-26T10:05:35Z

Add "Select source port" placeholder option to source port select in ui/tabs/workflows.js
Add "Select target port" placeholder option to target port select in ui/tabs/workflows.js
Both failing tests now pass (workflow-run-history-ui-regression.test.mjs and workflow-heavy-runner-integration.test.mjs)
Syntax check passes

Pull request overview

This PR introduces a “delegation watchdog” concept intended to detect/recover from stalled delegated workflows (especially non-task delegations), and updates workflow templates/tests to support the new behavior and Bosun-created PR detection.

Changes:

Added delegation watchdog defaults/config plumbing in action.run_agent, task lifecycle variables, and GitHub templates.
Added engine-side watchdog-based decisioning during interrupted-run recovery (resumeInterruptedRuns()).
Updated/added tests and mocks around templates and delegation recovery behavior.

Reviewed changes

Copilot reviewed 9 out of 9 changed files in this pull request and generated 8 comments.

File	Description
workflow/workflow-nodes/actions.mjs	Adds delegation watchdog config and retry loop to `action.run_agent` (but appears not wired into the main node registration path).
workflow/workflow-engine.mjs	Adds env-backed defaults + watchdog-based retry/exhaust decision during interrupted-run recovery.
workflow-templates/task-lifecycle.mjs	Adds watchdog variables + passes them into `agentPhase(...)` config.
workflow-templates/github.mjs	Expands “Bosun-created PR” detection to include body marker/phrase checks.
tests/workflow-templates.test.mjs	Loosens template-variable “is referenced” detection logic.
tests/workflow-templates-e2e.test.mjs	Extends `child_process` mock to include `execFileSync`.
tests/workflow-task-lifecycle.test.mjs	Adds an assertion test for newly installed watchdog defaults.
tests/workflow-run-history-ui-regression.test.mjs	Updates UI regression expectations for run-history labels/copy.
tests/workflow-engine.test.mjs	Adds engine watchdog recovery tests and `action.run_agent` stall recovery tests (currently contains a syntax-breaking stray block).

workflow/workflow-nodes/actions.mjs:322

workflow/workflow-nodes/actions.mjs does not appear to be imported/used anywhere in the repo (tests and runtime import workflow/workflow-nodes.mjs). As a result, the new delegation watchdog behavior and schema here likely won't take effect, and the new watchdog tests will still run against the implementation in workflow/workflow-nodes.mjs. Please mirror these changes into workflow/workflow-nodes.mjs (or wire this module into the registration path) so there's a single authoritative action.run_agent implementation.

Workflow template changes here will affect the generated demo defaults bundle. The repo has a sync test that expects ui/demo-defaults.js and site/ui/demo-defaults.js to match the output of node tools/generate-demo-defaults.mjs, so these files likely need to be regenerated and committed as part of this PR.

tests/workflow-templates.test.mjs

        const used = strings.some((text) =>
          text.includes(`{{${key}}}`) ||
          text.includes(`$data?.${key}`) ||
-          text.includes(`$data.${key}`),
+          text.includes(`$data.${key}`) ||
+          text.includes(`?.${key}`) ||
+          text.includes(`.${key}`),


Expanding the “variable is referenced” check to text.includes(?.${key}) / text.includes(.${key}) makes the test prone to false positives (e.g. a variable named id, sdk, timeoutMs will match many non-variable property accesses or JSON snippets). This weakens the guardrail and can let genuinely unused template variables slip through. Prefer a more targeted pattern (e.g. regex for {{key}} or $data access paths that end in the key) rather than any .${key} substring.

+    const mockEngine = {
+      list: vi.fn().mockReturnValue([
+        {
+          id: "wf-backend",
+          name: "Backend Agent",
+          enabled: true,


This block leaves a stray const mockEngine = { ... } outside of any it(...)/function scope, which will cause a syntax/runtime error and prevent the test suite from running. Remove the orphaned block or wrap it in the intended test case (and ensure braces/parentheses are balanced).

+    Math.trunc(Number(
+      watchdog.maxRecoveries
+      ?? watchdog.delegationWatchdogMaxRecoveries
+      ?? detail?.data?.delegationWatchdogMaxRecoveries
+      ?? DEFAULT_DELEGATION_WATCHDOG_MAX_RECOVERIES,

+  const recoveryAttempts = Math.max(
+    0,
+    Math.trunc(Number(watchdog.recoveryAttempts)
+      || (watchdog.recoveryAttempted === true ? 1 : 0)),


buildDelegationWatchdogDecision() currently uses Number(...) || DEFAULT... when parsing maxRecoveries and recoveryAttempts. That means explicit 0 values are ignored (e.g. setting maxRecoveries: 0 will be treated as the default, not "disable retries"). Use nullish coalescing / explicit Number.isFinite checks so 0 is honored and only null/undefined/NaN fall back to defaults.

Conflicts in all 4 files have been resolved in commit 39059d6. In addition to the conflict resolution, the following reviewer feedback was addressed: Number.isFinite checks in buildDelegationWatchdogDecision, tighter variable reference pattern in the template test, removal of unused watchdog variables from template-bosun-pr-watchdog, fixed stray const mockEngine orphan block in the test file, and demo-defaults regenerated. All 318 affected tests pass.
