# NORTHLINE five-card manual carousel brief

**FICTIONAL FILLED EXAMPLE — HOLD, NOT APPROVED FOR PUBLISHING**

This brief demonstrates a manual sequential carousel for one product. Replace every fictional value with your approved product, copy, rights, destination, platform, and measurement records. Confirm current format availability and preview every delivered placement in the account that will run it.

## Release identity

- Carousel ID: `NL-VITC-CAR-01`
- Version: `v1`
- Product: fictional NORTHLINE Vitamin C 30 ML pump bottle
- Sold configuration: exactly one bottle
- Sequence job: move from product identity → inspectable package → quiet context → purchase clarification → exact destination
- Order policy: `LOCKED_SEQUENCE`
- Release state: `HOLD`
- Hold reason: card `C3` uses a generated secondary candidate whose bottle, pump, and label geometry require product-owner approval or replacement
- Primary destination: `FICTIONAL:/products/northline-vitamin-c-30ml`

## Product authority

Approved source file: `public/images/blog/ai-product-photo-fidelity-test/source.webp`

Visible facts supported by that source:

- exactly one cylindrical clear bottle and clear cap;
- amber-orange liquid;
- silver stepped pump assembly;
- white rectangular label;
- exact visible text `NORTHLINE`, `VITAMIN C`, and `30 ML`.

Not established: ingredient list, concentration, efficacy, routine, skin result, certification, rating, testimonial, price, discount, stock, shipping, popularity, reverse label, package contents beyond the one bottle, or customer experience.

## Card sequence

### C1 — Identify the product

- Job: factual opener
- Asset: approved source
- Deterministic overlay: `NORTHLINE / VITAMIN C / 30 ML`
- Destination: exact fictional product page
- Acceptance: one product, exact visible label, no offer or result

### C2 — Make the package inspectable

- Job: detail crop of the approved source
- Asset: approved source crop, not a generated reverse or new angle
- Deterministic overlay: `30 ML / PUMP BOTTLE`
- Destination: exact fictional product page, optionally a product-details anchor after it is verified
- Acceptance: the pump, label, and quantity remain readable at final delivered crop

### C3 — Add one quiet context

- Job: secondary lifestyle context
- Asset: real Nano Banana 2 first return from job `f8ccc2d9-1d7e-420e-98c9-cf6e4e9929b9`, seed `2608162`
- Overlay: none
- Destination: exact fictional product page
- Acceptance: compare bottle, pump, cap, label size, and proportions with the approved source
- Current disposition: `SECONDARY_REVIEW`; blocks complete-carousel release until approved or replaced

### C4 — Clarify what the shopper is inspecting

- Job: product-clarity card
- Asset: approved source in a deterministic layout
- Deterministic overlay: `ONE 30 ML PUMP BOTTLE`
- Destination: exact fictional product page
- Acceptance: copy is supported by the source and matches the sold configuration

### C5 — Route to the exact destination

- Job: close the sequence without inventing an offer
- Asset: approved source in a deterministic layout
- Deterministic overlay: `VIEW THE EXACT PRODUCT`
- Destination: exact fictional product page
- Acceptance: no price, discount, urgency, stock, shipping, rating, or result is implied

## Platform preview gate

Record these checks from the actual account and placement before release:

1. Manual carousel format is available for the selected objective and setup.
2. All five cards are present; no catalog item or related media was inserted.
3. Card order is C1 → C2 → C3 → C4 → C5 in every placement where sequence matters.
4. Each card uses the declared image, headline, description, and exact destination.
5. Platform-generated crop, text, music, motion, layout, or enhancement does not change the approved meaning.
6. CTA overlays do not cover critical product or copy areas.
7. Mobile preview remains readable without relying on the previous or next card.
8. The exact released ad ID, preview evidence, file hashes, and reviewer are recorded.

## Measurement contract

- Decision: does this five-card sequence produce a better downstream business outcome than the declared control?
- Control: name the exact single-image or prior carousel asset and ad ID.
- Fixed: product, variant, offer, primary text, audience, placements, destination, optimization event, attribution treatment, budget rule, and test window.
- Primary outcome: purchase or the downstream event the campaign is genuinely optimized for.
- Diagnostics: impressions, delivered-card order where observable, outbound click, landing-page view, add-to-cart, checkout, and purchase.
- Guardrails: wrong-product questions, claim complaints, mismatched-variant sessions, support contacts, returns, and tracking failures.

Do not call one card or the sequence a winner from CTR alone. Report raw counts and denominators when the sample is small.
