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.
