Introduces the four rpc-layer seams docs/08-porting.md calls for this lane: platform::Wakeup (eventfd), platform::peer_of (SO_PEERCRED/struct ucred, same-UID check preserved unchanged), platform::acquire_instance_lock (abstract-namespace socket), platform::runtime_base_dir/data_base_dir (XDG lookups). Today's Linux code moves unchanged into daemon/src/rpc/platform/linux/; the seam headers carry no OS types and no #ifdef. No fifth interface for timerfd: EventLoop gains a portable add_timer() that folds the next deadline into poll()'s own timeout, replacing both timerfd instances in main.cpp — the loop already computes a deadline, so this needs no per-OS backend at all. Full suite 59/59 green; no #ifdef outside platform/linux/, no behaviour change. Co-Authored-By: Claude Sonnet 5 <[email protected]>
