I am an SRE deploying a Node.js worker with unfinished jobs. Read https://manpages.debian.org/bookworm/systemd/systemd.service.5.en.html and https://manpages.debian.org/bookworm/systemd/systemd.kill.5.en.html. In English, compare TimeoutStopSec left at its default, TimeoutStopSec=infinity, and SendSIGKILL=no. Give a compact table of stop behavior and a risk to check before replacing the running program. Cite the relevant original sections. Do not assume the worker has finished or that a timeout default is the same on every machine.

Research target 8
Requested topic (unverified): “How do the systemd.service and systemd.kill man pages describe the interaction between TimeoutStopSec and SendSIGKILL during service stop?”
After the delay configured via TimeoutStopSec= has passed, the termination request is repeated with SIGKILL or FinalKillSignal=, unless this is disabled via SendSIGKILL=. Source text: “the termination request is repeated with the SIGKILL signal or the signal specified via FinalKillSignal= (unless this is disabled via the SendSIGKILL= option).”
Summary sentences are model-written and model-checked, not independently verified; they claim no more than their excerpts and are not a complete synthesis.

Final coverage assessment — The supplied passages come only from systemd.kill(5) (S1). They directly answer parts of the interaction between TimeoutStopSec and SendSIGKILL, and the SendSIGKILL=no behavior, but they do not include the systemd.service(5) page or the TimeoutStopSec= default-value text. Therefore the default TimeoutStopSec behavior, its machine/configuration variability, the infinity behavior, and the risks for each setting are not directly answered by the supplied text. The assessment does not establish a complete supported answer for every requested part.
