Every harness memory plugin sent OpenViking requests under Node's default
`user-agent: node`, so server-side and gateway logs could not attribute
traffic to a harness or a plugin version.
Send `openviking-memory-<harness>/<version>` from all six harnesses
(claude-code, codex, opencode, pi, cursor, trae) on both the data plane
and the MCP proxy. Versions come from each harness's own manifest, or
from OPENVIKING_INTEGRATION_VERSION for cursor/trae; an unreadable
manifest degrades to 0.0.0 rather than throwing inside a short-lived hook.
The header is purely informational — neither the open-source server nor
the commercial gateway consumes it, and no auth or identity header
changes.
* Batch add-message writes across memory plugins
* fix(plugins): stop batch enqueue at first failure and bump plugin versions
Keep pending-queue entries a contiguous prefix when a mid-stream enqueue
fails: consumers mark the first sent+queued payloads as captured, so a
queued entry after a gap could silently drop the gapped message.
Bump claude-code 0.4.3, codex 0.7.3, opencode 0.2.3, cursor/trae 0.1.2 so
existing installs pick up the batch write path.
* fix(plugins): pin MCP-Protocol-Version header to the negotiated version
The shared stdio proxy forwarded the client's un-negotiated
protocolVersion ask as the MCP-Protocol-Version header on initialize and
cached it for follow-up requests, never reading the version the server
actually negotiated in the initialize response. Strict streamable-HTTP
upstreams (e.g. modelcontextprotocol/go-sdk servers) validate that header
on every request and answer HTTP 400 'Unsupported protocol version'
before negotiation can run, so clients on a newer spec than the upstream
(Trae sends 2025-11-25) failed MCP registration outright.
Send the proxy default (2025-06-18) while initializing, adopt
result.protocolVersion from the initialize response for all subsequent
requests, and keep the client's ask intact in the forwarded initialize
body so end-to-end version negotiation still happens.
* chore(plugins): bump patch versions for the MCP proxy protocol fix
claude-code 0.4.2, codex 0.7.2, cursor 0.1.1, trae 0.1.1, opencode 0.2.2.
