Second PR call follows dev-server stop and restart. Copilot resumed native session 5c2eba14-de42-43fc-adcb-3ed856735fcc in a new provider process; direct HTTP tool succeeded again.

NEARBY: Codex gpt-6.1-sol direct list_thread_pull_requests succeeded on main and PR, both returning {"pullRequests":[],"chains":[]}.

CHECKS: blacksmith-check: 126 focused ACP tests passed across AcpRegistryAdapterV2, AcpAdapterV2, AcpJsonRpcConnection and AcpRegistryProbe. check:changed aa11ef6783da81039e6646e2e96941748afb358e passed format, lint, knip, graphql, typecheck (13 packages), tests (17).

NOT VERIFIED: native Windows/macOS desktop and iOS/Android; remote/relay/tunnel connections; live no-HTTP and native-ACP providers; fork/replacement/explicit credential rotation outside server restart. Existing tests cover transport preference, fallback and rotated tokens.
