We need a graceful stop procedure for a Node worker on Windows. Use https://nodejs.org/api/process.html#signal-events and https://nodejs.org/api/process.html#event-exit to give a shutdown checklist covering stopping new jobs, finishing or journaling in-flight work, async cleanup and a hard deadline. Distinguish Windows signal limitations and the process exit event from POSIX expectations. Mark unproven application design advice explicitly.

> ⚠ Low confidence — Only source excerpts are delivered; complete synthesis and per-assertion support remain unverified. Evidence assessment: 6 sub-claims remain below the evidence threshold within budget. Treat this as provisional.
Source excerpts only. The draft is withheld as a conclusion; complete synthesis is unverified. Qualifying source excerpts are quoted below. Research targets are topics to investigate, not established conclusions.
Research target 1
Requested topic (unverified): “What does the Node.js process documentation say about signal events, including which signals are supported and how they behave on Windows versus POSIX?”
- “'SIGTERM' and 'SIGINT' have default handlers on non-Windows platforms that reset the terminal mode before exiting with code 128 + signal number.” - “Signal events are emitted asynchronously, so Node.js may exit before the listener is called if the event loop is otherwise empty.”
Research target 2
Requested topic (unverified): “What does the Node.js process documentation say about the process exit event, including when it fires and what can or cannot be done in its handler?”
Evidence gap: no qualifying excerpt for this research target.
Research target 3
Requested topic (unverified): “What are the Windows-specific limitations for receiving and handling signals in a Node.js process compared with POSIX expectations?”
- “On Windows, where POSIX signals do not exist, signals are handled as follows.” - “'SIGKILL', 'SIGTERM', 'SIGINT' and 'SIGQUIT' terminate the process forcefully and abruptly (similar to 'SIGKILL'); any other signal whose name is known on Windows (such as 'SIGHUP') does the same.” - “'SIGWINCH' is not terminal and is not coerced: subprocess.kill() throws an ENOSYS error and the child keeps running.” - “A signal name that does not exist on Windows (such as 'SIGSTOP') throws an ERR_UNKNOWN_SIGNAL error.”

Sub-claim "What does the Node.js process documentation say about signal…": 50% covered by S1, S2 — S1 states signal events are emitted when the process receives a signal and references POSIX signal names; S1 notes SIGTERM/SIGINT default handlers on non-Windows and asynchronous emission. S2 adds Windows signal handling behavior for child processes. However, the supplied passages do not include the process page's explicit Windows signal limitations section or a full supported-signal list, so this is partial.
Sub-claim "What does the Node.js process documentation say about the pr…": 10% covered by S1 — S1 includes process.exit() and exitCode passages, but no supplied passage from the process exit event section describes when 'exit' fires or what can/cannot be done in its handler.
Sub-claim "What are the Windows-specific limitations for receiving and …": 40% covered by S1, S2 — S2 directly describes Windows signal handling for child processes, including forceful termination and unsupported signals. S1 only notes non-Windows default handlers and POSIX signal names. The process page's own Windows limitations are not supplied, so coverage is partial.
Sub-claim "How should a Node worker stop accepting new jobs as part of …": 10% covered by S1 — The supplied passages mention shutdown and avoiding new event-loop work, but do not describe stopping new jobs or a worker/job-queue mechanism.
Sub-claim "How should a Node worker finish or journal in-flight work du…": 10% covered by S1 — S1 notes process.exit() can abandon pending asynchronous operations, but no supplied passage gives a procedure for finishing or journaling in-flight work.
Sub-claim "How should asynchronous cleanup be performed during a Node w…": 20% covered by S1 — S1 advises setting process.exitCode and allowing natural exit rather than process.exit(), which is relevant context, but it does not provide an async cleanup procedure for a worker shutdown.
Sub-claim "How should a hard deadline be enforced for a Node worker gra…": 0% covered — No supplied passage addresses enforcing a hard shutdown deadline.
Sub-claim "Which parts of the shutdown checklist are unproven applicati…": 20% covered by S1 — S1 provides documented behavior about process.exit(), exitCode, and signal event timing, which can help distinguish documented behavior from design advice, but the supplied passages do not explicitly label checklist items as unproven design advice.
Coverage is weak for several application-design sub-claims, but the remaining budget is 0.015 and no skipped source is affordable. The free skipped sources cannot be purchased because the budget is effectively exhausted; therefore no additional sources are recommended.

Final coverage assessment — The supplied excerpts from the Node.js process and child_process documentation directly answer the signal-event and Windows-vs-POSIX signal questions, and partially answer the process-exit question. However, the cited process.html excerpt does not include the 'exit' event section, and neither source provides a shutdown checklist for stopping new jobs, finishing/journaling in-flight work, async cleanup, or a hard deadline. Those are application-design recommendations that must be marked as unproven relative to the cited pages. The assessment does not establish a complete supported answer for every requested part.
