Development record

The published abcd v0.15.1's prompt-router hook ran for 7 to 10 seconds at about 99% CPU per prompt in a busy session on 2026-10-25 (one sample: pid 98266, 9 s; another: pid 370, still running at 7 s), on a 10-core machine at load 25 where an endpoint scanner already takes about four cores. The hook has a one-second contract (TestThePromptHookReturnsInsideItsSecond), but on a loaded machine nothing holds it to that: a session that receives many messages pays a full core for most of every ten seconds, which slows every preflight on the machine and delays each reply.
