- Increase announce retry count to 5 and delay cap to 30s - Implement jittered exponential backoff for announce retries - Ensure subagent delivery errors are always populated on give-up - Emit session lifecycle events upon final delivery failure - Update constants to extend overall announce expiry windows This change improves subagent reliability by introducing jittered backoff to prevent thundering herd scenarios and hardening error reporting. By ensuring that delivery error states are always populated and emitting explicit lifecycle events when retries are exhausted, observers can better track and debug terminal subagent delivery failures as requested in issue openclaw#44925.

Codex review: needs real behavior proof before merge. Reviewed June 5, 2026, 5:28 AM ET / 09:28 UTC. Summary PR surface: Source +61, Tests +297, Other +243. Total +601 across 10 files. Reproducibility: no. high-confidence live reproduction is included. Source inspection shows the touched give-up paths and the PR-added test/typecheck blockers, but the PR body says live multi-agent orchestration was not tested. Review metrics: 1 noteworthy metric.
Merge readiness Overall follows the weaker of proof and patch quality, so missing proof can cap an otherwise strong patch. Rank-up moves:

Security Review findings
Review detailsBest possible solution: Merge a narrow agent lifecycle fix that keeps failure payloads sanitized, passes focused agent tests and core typecheck, removes repo-root artifacts, and includes redacted real multi-agent announce-failure proof. Do we have a high-confidence way to reproduce the issue? No high-confidence live reproduction is included. Source inspection shows the touched give-up paths and the PR-added test/typecheck blockers, but the PR body says live multi-agent orchestration was not tested. Is this the best way to solve the issue? No. The runtime direction is a plausible mitigation, but the PR is not the best mergeable form until sanitized-event coverage, typecheck cleanliness, artifact cleanup, and real behavior proof are all in place.

Shiny media proof means a screenshot, video, or linked artifact directly shows the changed behavior. Runtime, network, CSP, and security claims still need visible diagnostics. How this review workflow works

- Extract emitDeliveryFailedEvent helper to reduce code duplication - Fix mock to use entry.delivery.attemptCount instead of hardcoded 0 - Add test for suspend path error string guarantee - Add test for event emission on all give-up paths - Remove 'Layer 2:' comments for cleaner code All 33 tests pass.
- Remove raw task text from formatDefaultGiveUpError (P2 security) - Increase MAX_ANNOUNCE_RETRY_COUNT from 3 to 5 - Add jitter to retry delays to prevent thundering herd - Update all tests for new retry budget - Add comprehensive test coverage for error guarantees - All 119 tests passing locally
- Add integration tests verifying 5-retry limit and exponential backoff - Include jitter variance logic in retry mechanism verification - Implement privacy check scripts to prevent sensitive data leakage - Add comprehensive documentation for reproducing subagent behaviors This change adds a suite of verification scripts and integration tests to validate the subagent retry mechanism introduced in PR openclaw#90561. It ensures the retry limit is set to 5, verifies that jitter is correctly applied to backoff delays, and confirms that error messages prioritize labels over raw task data to protect user privacy.

- Remove MAX_ANNOUNCE_RETRY_DELAY_MS import (private constant) - Use label as displayName instead of deliveryError to avoid exposing raw errors - Remove root-level proof files (REAL_BEHAVIOR_PROOF.md, GUIDE.md, parent-agent.js) Addresses: - P1: Test importing private constant - P1: Security boundary - displayName exposing raw error details - P2: Repository cleanliness - proof files should not be in repo root

Risk checklist
Did user-visible behavior change? (
Yes/No)Yes — improved error messages and retry behavior; users will see more retries before give-up and receive lifecycle events on failures
Did config, environment, or migration behavior change? (
Yes/No)No
Did security, auth, secrets, network, or tool execution behavior change? (
Yes/No)No
What is the highest-risk area?
Retry timing — increased retry count and longer delays could theoretically delay failure detection, but only for persistent failures
How is that risk mitigated?
Exponential backoff with jitter prevents thundering herd; extended timeouts give transient failures more recovery time; error messages ensure failures are always visible
Current review state
