Stage O-A: the Tripod is an observer -- outside the compudynamic comparison, acting on events (FABRIC-3.9.0 §2, 3.9.8)

Browse Source 
Observer flag on switch-signal slots, set by the kernel for the Tripod
(is_fleet_foundation, hoisted; Hera in kernel_main). The decision: an
observer in progress or holding an event keeps the CPU; observers with
events (mail, Hera's console input) go ahead of participants, oldest wait
stamp first; participants compared by work heat as before. Observers are
never charged (O-2) nor floored. Uncommitted heat-share charge discarded.

Evidence, byte-identical amd64/aarch64/riscv64: G interleave unchanged;
Hestia's mail runs before any worker output (HHHABB...); a line typed
while two workers run is read and executed mid-stream (...ABAB1 2 + . /
3 ok / ABAB...) -- console responsive under load. Relay 3, dict_hash
unchanged. Busy-wait DOE deliberately not run (deadlocks by design until
O-C). FABRIC-3.9.0 records rulings and Captain Bob's messaging note (§7).
