Ticket 31691 - Check the included AUX cable and full seating before treating the whine as abnormal

• automation_draft_weakness: The earlier automation draft asked for video, power-supply label, and proof of purchase, but it did not explicitly test whether the reported AUX-triggered whine was partly caused by cable choice or a partially seated 3.5 mm connection.
• manual_reply_improvement: The newer public support reply narrowed the next test by asking the customer to use the included 3.5 mm audio cable and to make sure both ends are fully inserted before treating the persistent whine as abnormal and waiting on video.
• new_drafting_rule: For haptics whine tickets where the customer says noise starts when an AUX cable is inserted, first verify that they are using the included 3.5 mm cable and that both ends are fully seated; only then treat continued loud whine as abnormal and move toward the evidence/replacement branch.
• confidence_effect: Improves future diagnostic sequencing for unresolved haptics-whine cases without claiming the PSU is the final cause.
• storage_decision: reviewable learning proposal

Why this matters

This keeps future whine drafts from jumping too quickly to PSU review when the next high-signal branch is still a basic included-cable and full-seating check.
