The handoff catch in session-handoff.ts and the /handoff handler in
command-controller.ts mapped any error named AbortError to "Handoff
cancelled" regardless of whether the handoff signal was actually
aborted. Providers throw name-AbortError errors on non-user conditions
(stalls, idle timeouts, nested resolution failures), so a genuine
generation failure surfaced as a user cancellation and hid the cause.
Only report "Handoff cancelled" when handoffSignal.aborted is set;
re-throw the real error otherwise. The controller now trusts the
normalized "Handoff cancelled" message and drops its own AbortError
check so re-thrown provider failures render as "Handoff failed: ...".
Fixes#7903
- container stubs gained disposeChildren for the stale-renderer teardown paths
- login-stored API key assertions include the new source provenance field
- bash timeout test covers the zero-disable contract alongside the clamp
- skill keyword steering activates a task tool for the gated workflow notice
- Introduced `generateHandoffFromContext` to enable provider-aware oneshot generation and improved cache hit rates via the live-turn pipeline.
- Updated `buildSideRequestContext` to support pinning custom system prompts, preventing per-turn hook leakage during handoff.
- Added concurrency guards across CLI and RPC modes to block manual `/handoff` requests while a session is actively streaming.
- Standardized handoff execution to force `toolChoice: "none"` and enforce consistent cache-routing behavior.
- Reworked createAbortableStream to forward abort signals to the source stream reader.
- Added cleanup logic so abort/cancel/error paths release locks and emit AbortError consistently.
- Updated related tests to verify source-stream cancellation and handoff escape-handler behavior.
- Updated the catalog changelog by removing a duplicate `Fixed` heading and leaving the NVIDIA Qwen fix in the current release notes.
- Restructured the coding-agent changelog by moving unresolved fixes into Unreleased and removing duplicated historical entries.
- Added `requestComponentRender` to mocked `ui` objects in coding-agent controller tests to match the updated interface.
