Large git diff/exec responses (up to MAX_GIT_BUFFER=10MB) were sent as one JSON-RPC frame on the shared SSH channel. encodeJsonRpcFrame's synchronous JSON.stringify + Buffer.from of the whole payload, plus the multi-MB write, head-of-line-blocked interactive pty.data echo: opening a big diff (e.g. a lockfile) over SSH while typing in another pane stalled the echo for seconds. The 2026-07 fs.readFileStream fix added a per-client serialized bulk lane (RelayDispatcher.notifyBulk) honoring write()===false + waitWriteDrain, plus an ack credit window — but only fs streams used it; git responses never did. Stream the diff family (git.diff/branchDiff/commitDiff) and git.exec through the bulk lane in chunks with the same ack-window backpressure. The relay returns a small sentinel result and pumps git.responseChunk frames; the client reassembles and JSON.parses. Small responses stay single-frame. Cross-version safe via an opt-in capability gate (no handshake change): - client sends __streamResponse:true; old relays ignore it → single-frame. - new relays only stream when the flag is present → old clients get single-frame. - new client checks for the stream sentinel; a plain result (old relay) is returned directly. STREAM_CHUNK_SIZE is untouched; git chunking uses its own GIT_RESPONSE_CHUNK_SIZE and the client reassembles by concatenation, so chunk size is not baked into any cross-version offset math.
