It adds regression tests and patch changesets for these features. ChangesWeb access origin handling
Agent telemetry and subagent recovery
Session journal shutdown
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The change improves journal shutdown coordination, but post-close event handling lacks direct regression coverage, leaving a bounded risk of shutdown-time journal writes. Sequence Diagram(s)sequenceDiagram

- Line 52: Update browserOpenOrigin to detect raw IPv6 hosts and wrap them in
brackets before constructing or returning the origin, while preserving existing
wildcard and non-IPv6 behavior. Add a regression covering --host ::1 --open to
ensure openUrl receives a valid URL.
In `@packages/agent-core-v2/src/agent/tools/agent/agentTool.ts`:
- Around line 358-363: Update AgentLifecycleService.doCreate so
sessionMetadata.registerAgent() completes before setting managed.active and
exposing the handle, ensuring handleOf and resolveResumeTarget always see
registered metadata. Preserve ownership validation through the metadata parent
check and remove any obsolete ensureOwnedIdleSubagent references.

Summary
Agent(resume=<id>)now rebuilds a persisted subagent from session metadata when it is not live in the current process, instead of failing with "does not exist". The rebuilt subagent syncs to the caller's current permission mode (unless tower-pinned) and approval rules match its persisted profile label.pfc_*events carrymodelalongsideprovider_type/protocol.--opennow rewrites a wildcard bind origin (0.0.0.0/::) tolocalhostfor the browser, and the ready banner parses the port withoutnew URL(which throws on::).Risk
