Main: 575579d68ac4bae09f8426a345d4a3eac1e90c67 (github/main)
PR: 9f99f3d446787f5dd4a6daf16ed4627b34e9727e

Setup: installed dependencies with vp i in both checkouts. One background dev server at a time. Main worktree /home/user/main; PR checkout /home/user/t3code. Main app created isolated source state; target state /tmp/pr28405-target created by dev server. Enabled Linked environments using Settings > Labs. Added real /home/user/t3code project using Add project > Local folder. No fixtures, mocks, demo provider, or direct database writes.

BLACKSMITH
65 focused tests passed across PeerLinks, PeerMcpClient, PeerForwarding, RemoteDelegation, PeerLinkRequests, including real HTTP cancellation regression.
check:changed initially lacked base history in source snapshot. Fetched PR head with depth 2, then ran vp run check:changed 9f99f3d^ through blacksmith-check.

  CI also runs: full test suites, build

  pass not cached: files changed during the run



Limits: no claim about latency, CPU or memory improvement; debugger confirms API construction scope only. Native desktop/mobile, relay/WAN transport, remote delegated provider turns, and cancellation against a stalled live peer were not exercised manually. Cancellation passed the existing real HTTP regression on Blacksmith.
