Executive Summary — Read This First
A Proof-of-Diligence record is evidence that independent review occurred.
It is not a guarantee that every issue was found. It is not a legal certification. It is a structured, time-stamped record that shows a reasonable independent review process happened — that platform-reported metrics were not blindly accepted, but reviewed against independent verification signals.
Every Ad IntellX report includes a Proof-of-Diligence record. Every Agency Proof-of-Stewardship Ledger includes one for each client account reviewed.
Definition
What Proof of Diligence is
Proof of Diligence is a documented record showing that an independent verification process occurred at a specific point in time for a specific ad account.
The concept parallels what exists in other high-stakes verification contexts. A car inspection creates a record. A financial audit creates a record. A building inspection creates a record. These records do not guarantee the absence of all problems — they document that a reasonable, independent review process took place.
In digital advertising, no such record has existed by default. Advertisers have accepted platform dashboards as both the source of activity data and the proof that activity was healthy. Ad IntellX creates a third-party Proof-of-Diligence record that sits outside the platform's own reporting system.
"The audit shows what happened. The Proof-of-Diligence record shows that an independent reviewer looked at what happened and documented their findings."

Record Structure
The 10 fields in every Proof-of-Diligence record
Every Ad IntellX Proof-of-Diligence record contains the following fields. These fields are fixed — they cannot be omitted or modified after generation.
Proof-of-Diligence Record — Sample Structurev1.0 Format
01
Account Reviewed
The Meta Ad Account ID of the account reviewed. Displayed as the last 4 digits for privacy in shared contexts (e.g., Ad Account ending in ····4821).
02
Date Reviewed
The UTC timestamp when the verification process completed. Format: ISO 8601 (YYYY-MM-DDTHH:MM:SSZ). This timestamp is immutable once set.
03
Data Source
How the verification data was obtained: "Advertiser-authorized Meta Marketing API (OAuth read-only)" or "Advertiser questionnaire (no API connection)." Source type affects the confidence classification of the report.
04
Review Period
The date range covered by the verification review (e.g., "March 24, 2026 — June 22, 2026 — 90-day window"). All findings are scoped to this period.
05
Findings Identified
The number of risk signals identified, broken down by severity: X Critical, X Elevated, X Low. Does not list the specific findings (which are in the full report).
06
Actions Recommended
The number of recommended actions included in the report. Confirms that the verification produced actionable output, not just observations.
07
Follow-up Status
For Monthly Ad Health Reports: whether prior-period findings were resolved, partially resolved, or remain open. Initial audits show "N/A — first review."
08
Reviewer / System ID
The Ad IntellX verification system identifier and report version number. Enables Ad IntellX to reconstruct and validate any report record.
09
Report Version
The Ad IntellX report format version used to generate the findings (e.g., Report Format v3.1). Enables interpretation of the report structure against the corresponding methodology documentation.
10
Limitations Acknowledged
A confirmation that the advertiser or reviewer was shown the methodology limitations statement, and the version of that statement that was in effect at the time of the review.
Scope
What Proof of Diligence is not
The Proof-of-Diligence record is designed with intentional limitations to ensure it cannot be misrepresented.
It is not a guarantee that all issues were found
The Proof-of-Diligence record confirms that a reasonable independent review occurred. It does not guarantee completeness. Verification has known limitations (documented in the Methodology page). The record explicitly acknowledges these limitations.
It is not a legal certification
A Proof-of-Diligence record is not a legal audit, a regulatory certification, a court-admissible document by itself, or evidence of legal compliance. It is a verification record created by a private verification service. Any legal interpretation of this record requires qualified legal counsel.
It is not a performance guarantee
The existence of a Proof-of-Diligence record does not guarantee campaign results, revenue, return on ad spend, or any specific business outcome. It documents that independent review occurred, not that the account will perform at any particular level.
It is not immutable after revocation
If an advertiser revokes their OAuth authorization, Ad IntellX can no longer refresh or update the verification record. Prior records remain valid for the period they cover. Future records cannot be generated without re-authorization.
Product Integration
Where the Proof-of-Diligence record appears
The Proof-of-Diligence record is embedded in every Ad IntellX product that produces a verification output.
Ad Spend Verification Report
Every paid report unlock includes a Proof-of-Diligence record at the bottom of the report
Monthly Ad Health Report
Each monthly report includes a fresh Proof-of-Diligence record for that month's review
Agency Proof-of-Stewardship Ledger
Each monthly ledger includes a Proof-of-Diligence record for every client account reviewed
Agency Use
How agencies use Proof of Diligence
The Proof-of-Diligence record is a core component of the IntellX Seal agency verification system. Agencies use it to demonstrate active, documented account stewardship.
Every month, verified agencies generate a Proof-of-Stewardship Ledger for each client account under their management. The ledger contains a Proof-of-Diligence record showing that independent verification of that client's account occurred during the month — not just that the agency ran campaigns.
"Do not just tell clients you are watching their ad spend. Show them a monthly Proof-of-Stewardship Ledger."
Ad IntellX Agency Positioning
The Proof-of-Diligence timestamp in the ledger cannot be backdated or manually created. It is generated by the verification system at the time verification occurs. This makes it a credible, tamper-evident record of agency stewardship.
What the Proof-of-Diligence Record Does Not Prove
The presence of a Proof-of-Diligence record confirms that verification occurred. It does not prove:
That the agency made good campaign decisions
That the advertiser's budget was spent optimally
That all issues were identified and resolved
That platform-reported performance is accurate
Legal compliance or financial audit completion
