Write a sponsor integration that doesn't tank retention or skip legal disclosure

You are writing a sponsored segment to integrate into an existing YouTube video — the actual ad-read script plus exactly where it goes and how it connects to the content on either side. A sponsor segment that interrupts the video with no bridge, and that omits required disclosure, costs the creator both retention and legal exposure; you are avoiding both.

VIDEO TOPIC AND WHERE THE SEGMENT WOULD GO
A video reviewing a mechanical keyboard build — segment needs to go somewhere in the middle, likely right after the switch-testing section and before the final assembly

SPONSOR AND WHAT THEY WANT MENTIONED
Sponsor is a password manager app; wants biometric unlock and a "breach monitoring" feature mentioned, plus a specific discount code MECH20

DISCLOSURE REQUIREMENT
Paid partnership — requires YouTube's built-in "Includes paid promotion" tag plus a clear verbal disclosure per FTC endorsement guidance

CHANNEL VOICE
Dry, technical, slightly self-deprecating about spending too much on hobby gear

SEGMENT LENGTH TARGET
45-60 seconds

INTEGRATION RULES
Never open the segment with a hard cut and a tone shift straight into "today's sponsor is" — bridge from the actual content into the segment with one or two sentences that connect logically, even loosely, to what was just being discussed, since a jarring transition is what makes a sponsor segment feel like an interruption instead of a continuation, and that feeling is what drives the skip. State the disclosure exactly as required by the type specified — this is not a stylistic choice the channel voice can override; "thanks to [sponsor] for supporting the channel" alone does not satisfy a paid-partnership disclosure requirement in most jurisdictions and platforms, and the specific required language or on-screen paid-promotion tag must be included, stated plainly, not buried in a mumbled aside. Write genuine, specific claims about the sponsor's product using only what's provided in the sponsor brief — do not invent a feature, statistic, or use case the brief didn't state, since a script that oversells the product creates a mismatch between the ad and the actual product a viewer might use, which damages channel trust with both the sponsor and the audience. End the segment with a bridge back into the video's actual content that mirrors the opening bridge — the segment should feel like a bracketed aside the viewer can mentally file as "over now," not a fade-out that leaves the viewer unsure whether the sponsor talk is really done. Keep the segment at or under the stated length target; a sponsor read that runs long relative to what was promised to the channel's own audience is the single most common cause of a viewer skipping the whole next 30 seconds via the seek bar rather than just this one segment, since the visible drop in the timeline UI itself signals "this part is skippable."

OUTPUT FORMAT
1. The exact bridge-in line(s), the full ad-read script, and the bridge-out line(s), as spoken lines.
2. The required on-screen or verbal disclosure text, stated exactly and flagged clearly as non-negotiable.
3. Where in the existing video this segment should be placed and why that specific point, not an earlier or later one, minimizes the jarring-transition problem.
4. Confirmation the total spoken segment fits the length target.
