Full V2 fetch handshake (ls-refs + fetch with done + sideband pack) runs between real git 2.43 and a Rust listener over the alkcall Connection -> BiStream -> tokio-util compat -> gix-packetline path. Verification: git ls-remote, git clone (fsck --strict clean), incremental git fetch, annotated-tag checkout, in-process duplex selftest. All over alkcall 0.8 core types; the flagged futures-io risk resolved with a two-line tokio-util compat adapter. Findings: docs/research/poc-1-findings.md (deliverable; POC source stays disposable at /workspace/alkgit-poc1 per the standalone POC mode). Also records in the research docs: - git-protocol.md: observed done-path shape (no acknowledgments section), git:// first-request framing, advertise-once rule - gitoxide.md: gix-packetline async stop-delimiter + reset() contract - alk-stack.md: POC-1 verification item marked resolved - pocs.md: POC-1 status -> proceed
