Review the B2B ad brief and proposed creative I paste below. Your job is to find the changes required before a producer can make it and before a buyer can understand the offer. Work only from the supplied material. A brief that sounds polished can still fail this task.

REQUIRED INPUT
Paste: the complete brief; proposed copy/scenes; source material supporting each claim and permission status; the actual resource/product material; destination copy or URL plus observed behavior; requested channels and production limits. If one is unavailable, label it unknown. A URL alone does not prove its contents. Do not claim to have opened files, run a browser, checked permissions or tested a download unless you actually did so.

REVIEW TASK
1. Identify the buyer, their task, the offer and the post-click requirement in one sentence each. If the supplied information cannot establish one, list the focused question needed.
2. Trace each factual claim/quotation to evidence. Separate a source statement from independently verified results. Reject invented numbers, fake customer stories, altered quotes and unsupported performance inferences. Do not demand numerical performance proof for a truthful description of a file or observed product action.
3. Follow the proposed ad from first frame/opening to CTA to destination. Name any changed promise, missing condition, unreadable detail or extra commitment the ad fails to explain.
4. Attempt the production handoff on paper: for every scene/layout area, identify its asset, exact text, voice and owner. Flag steps that require unavailable people, product access or footage. An unassigned owner is an open item, not a name to invent.
5. If there is a blank and worked brief, map the fields one for one. If a follow-on prompt uses them, check that the fields supply its required inputs. Do not count matching filenames as a completed reader task.
6. Review measurement: what event is observed, where it is recorded, the reporting window and attribution, and what the event cannot prove. Missing tracking stays missing. A download click is not a completed brief or sale.
7. Write only findings that change a reader or producer outcome. Each finding must give the exact location, consequence, smallest concrete repair and how to check the repair. Supply rewritten copy where the evidence permits it. Do not solve a missing fact with invented copy.

OUTPUT
- Decision: ready to produce / revise / stop this approach. Keep launch disposition separate.
- Blocking findings, then other improvements, each tied to its source location and repair check.
- Proposed repaired passages that use only supported facts.
- Missing inputs with owners if supplied, and what to test next.
If inputs are insufficient to judge the brief, say so and return questions plus the checks that can be completed. Do not issue a positive verdict from an outline alone. If the case is hypothetical, preserve that label.
