GET /logstream/stream on the hub HTTP transport: bearer-authenticated
Server-Sent Events with the event_list filter set, since_event_id /
Last-Event-ID replay-then-tail resume (live tail only without a cursor,
via new Logstream.latest_event_id), ~15s heartbeat comments, and a
bounded client pool (MEMPALACE_SSE_MAX_CLIENTS, default 8; 503 +
Retry-After on cap). Frames carry the exact event_list JSON envelope —
the compat surface promised to the PalaceMind desktop viewer.
Also fixes a latent hub-starvation hazard the first SSE consumer would
have tripped: do_POST serialized every request under the global HTTP
lock, so one agent's five-minute event_wait long-poll blocked the whole
fleet. Logstream tools (own WAL db, no Chroma/KG state) now dispatch
lock-free via _http_dispatch; everything else keeps the global lock.
Requested by claude-fable-5-windows for the PalaceMind live viewer
(correlation palacemind_desktop_logstream_viewer). Full suite: 3411
passed.
(cherry picked from commit a7c720507974acc2f02957ac24b7045503ad74da)
- website/concepts/agent-logstream.md: event/artifact model, delegation
loop, coordination-vs-memory table; added to the sidebar.
- website/reference/mcp-tools.md: schemas for the seven logstream tools;
tool count 35 -> 42 (README updated to match).
- website/reference/cli.md: mempalace logstream / mempalace artifact.
- website/guide/remote-server.md: hub doubles as agent coordination bus.
- integrations/shared/coordination-protocol.md: canonical shared-brain
protocol (identity, delegation loop, hard rules) with a copy-paste
system-prompt snippet; linked from recall-protocol.md and the
mempalace-recall skill so recall and coordination never blur.
