The 2026-09 change raised MEMPALACE_FEED_MINE_TIMEOUT_MS to 300 000 and
raced it against client.callTool("mempalace_mine"). But callTool() had no
way to carry a deadline, so every call went out under the transport's
generic per-request timeout (MEMPALACE_MCP_TIMEOUT_MS, 60 000), which fired
first on every honest 60 s+ mine. Operators saw
feed (tick) failed: mempalace remote request 'tools/call' failed:
timed out after 60000ms
instead of the message the change had aimed at, and the 300 s was
unreachable. On stdio it was worse than noise: that transport kills the
server child on timeout, so the mine was actually aborted at 60 s.
callTool(name, args, { timeoutMs }) now passes a per-call deadline to both
transports; feedPalace() uses it for the mine. Plain calls keep the short
default — a query taking 60 s is still wedged. The Promise.race stays as the
liveness guard for a transport with its timeout disabled (0).
scripts/test-mcp-call-timeout.sh cuts RemoteMcpClient out of the shipped
file (as test-owed-withdrawal.sh does for the mailbox predicates), drives it
against a local JSON-RPC server that delays tools/call, and asserts: plain
call rejects at the generic deadline; the override outlives it; the override
is itself a deadline. Fails on the previous commit (2 of 6), passes here.
Vendored-copy delta noted in the header; protocol untouched, sync token
unchanged (check-mcp-client-sync.sh passes against pi-extensions).
