Documents two issues discovered 2026-08-19:
- C1: review #008 fix (commit 4ab8c51) never deployed to dev1; the
running binary still leaks FDs (433/1024 after 8 days, ~9 FDs/min).
- C2: the watchdog in IdleTrackingService decrements in_flight when
the handler returns the Response, but for streaming responses (e.g.
git clone) the body is still in flight, so the watchdog can kill
the connection mid-stream. Requires an IdleTrackingBody wrapper
that owns the decrement until the body reaches EOF or is dropped.
