Approximate feed preview — check the final ad in Campaign Manager.

Use this brief for a company Page single-image ad with a website destination. Keep exact copy, URLs and source notes. Blank means Unknown.

[Full text here, even when the preview is collapsed.]

## Original and delivered creative

- Original asset ID / filename / MIME / bytes / SHA-256:
- Decoded, oriented source dimensions / EXIF orientation applied:
- Source and permission evidence ID:
- Output preset: Landscape 1200 × 628 / Square 1200 × 1200 / Portrait 720 × 900
- Fit or Crop: default Fit; no stretching
- Focal point: x / y in 0–1 coordinates
- Crop rectangle: x / y / width / height in oriented source pixels
- Solid export background:
- Removed edges / enlargement warning / important text or logo to inspect:
- Delivered asset ID / filename / MIME / pixel dimensions / actual bytes / SHA-256:
- Output status: Not generated / Generated
- Original retained unchanged: check actual bytes
- Placement consequence: Vertical paid images serve on mobile only

The production image contains only the selected artwork. The feed mockup includes the approximation label, mode and variant. Crop guides belong only in the inspection view. Do not label a planned output as generated.

## Destination and continuity

- Exact URL, including all tracking parameters:
- Syntax result: Pass / Needs changes / Unknown
- Expected arrival headline / action:
- Visitor commitment: read, download, register, demo or supplied action
- Access: Not inspected / Accessible / Inaccessible / Supplied excerpt only
- Observed arrival headline / actual next action:
- Inspected source link, file or exact excerpt:
- Check date / owner:
- Promise-to-destination judgment and reason:

A valid URL does not prove access or offer availability. An unvisited destination stays Not inspected. A supplied excerpt is not a live page inspection.

## Claim, quote and asset evidence

| Evidence ID | Exact claim, quote or asset | Source link/file/excerpt | What was inspected | Date | Factual status | Permission/approval status and reason | Reviewer / owner | Scope / provenance |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| EV- | Unknown | Unknown | Not inspected | Unknown | Unknown | Unknown | Assign owner | Current variant |

Known facts need inspected source evidence. Not applicable needs a route or evidence-specific reason. Hypothetical facts and simulated approvals must be labeled as such. Loading a sample clears real approval states.

## Review checks

| Check | Not checked / Pass / Needs changes | Applicable or derived Not applicable with reason | Variant / revision | Date | Evidence IDs | Reviewer | Provenance |
| --- | --- | --- | --- | --- | --- | --- | --- |
| Phone reading | Not checked | Applicable | | | | | |
| Desktop reading | Not checked | Applicable for landscape/square; portrait is mobile-only | | | | | |
| Image text and crop | Not checked | Applicable | | | | | |
| Copy, CTA and destination continuity | Not checked | Applicable | | | | | |
| Factual approval | Not checked | Applicable | | | | | |
| Asset-use approval | Not checked | Applicable | | | | | |
| Required legal copy | Not checked | Record any justified Not applicable reason | | | | | |

Only dated, scoped evidence supports Pass. Editing copy, file, crop, CTA, destination or evidence reopens affected checks and marks old exports stale. Preserve unrelated evidence. Presentation-only changes do not change content approval.

## External platform checks

| Check | Not checked / externally verified | Date | Account/campaign scope | Evidence source | Reviewer |
| --- | --- | --- | --- | --- | --- |
| LinkedIn approval | Not checked | | | | |
| Native rendering | Not checked | | | | |
| Objective-specific CTA availability | Not checked | | | | |
| Final tracking | Not checked | | | | |

This tool does not issue launch approval, submit an ad or authorize spending. Keep platform checks separate from production handoff.

## Technical results and exact open requests

- Hard requirement errors:
- Tool-cap errors, labeled separately:
- Recommendations:
- Unknowns, including ambiguous Unicode boundaries:

| Request ID | Subject / field | Owner or exact assignment request | Why needed | Exact evidence or action | Blocks technical, handoff or platform | Status |
| --- | --- | --- | --- | --- | --- | --- |
| REQ- | | | | | | Open |

Every required Unknown or Needs changes gets one stable request. Unsupported routes stay Hold with the relevant guide or native next step. Irrelevant fields are derived Not applicable with a reason.

## Attachment inventory and provenance

| Asset/export ID | Portable filename | MIME | Bytes | Oriented/output dimensions | SHA-256 | Included attachment or embedded state reference | Revision |
| --- | --- | --- | --- | --- | --- | --- | --- |
| | | | | | | | |

Include the original creative, logo and production image. A local path alone is not an attachment. Saved JSON must embed and verify the images; each image is capped at 5,000,000 bytes, all embedded decoded assets at 15,000,000 bytes, and serialized JSON at 22,000,000 bytes. These are tool caps. Decoded images are capped at 24,000,000 pixels before processing.

Reject malformed schema, missing/tampered assets or over-cap data without changing the accepted record. A sample clears actual reviews and approvals. Reset asks for a short confirmation.

## Dated guidance

Checked September 27, 2026. Refresh before publication; a failed refresh leaves current currency Unknown.

Counts use declared local grapheme clusters, with a disclosed codepoint fallback. LinkedIn's exact Unicode implementation is Unknown. Recommendations create warnings. Do not invent aspect-ratio tolerances, arbitrary-dimension rules or exact truncation points. JPG/PNG are supported here; LinkedIn also supports GIF, which this still-image tool rejects with a next step.
